Technical realization elements of casing components for telescopic and adjustable fuel pumps

Technical realization elements:

4. The technical problem to be solved by the present utility model is to provide a telescopic and adjustable fuel pump casing assembly for the above-mentioned shortcomings of the prior art, so that the overall adaptability of the fuel pump is improved, and it is suitable for the installation of fuel tanks of multiple specifications.

5. In order to achieve the above purpose, the present invention provides the following technical solutions: a telescopic adjustable fuel pump casing assembly, including a top cover, a casing, characterized in that the casing includes an inner bracket and a detachable package An outer stent covering the outer circumference of the inner stent is provided with an adapting adjustment mechanism that can adjust the relative installation height of the outer stent and the inner stent between the outer stent and the inner stent.

6. Using the above technical solution, by improving the structure of the shell, it is divided into an outer bracket and an inner bracket, and an adapting adjustment mechanism is further provided, so that the overall height of the shell can be changed according to the actual assembly environment, without changing the acceptance of the shell Function, the function of the shell is increased-height is adjustable, which improves the overall adaptability of the fuel pump and is suitable for installation of multiple specifications and types of fuel tanks.

7. The aforementioned casing assembly for a telescopic adjustable fuel pump can be further configured as follows: the adaptation adjustment mechanism includes a plurality of sets of clamping members arranged in sequence along the axis of the inner bracket and arranged on the outer periphery of the inner bracket, The outer periphery of the outer bracket is provided with several groups of linkage holes that are arranged in sequence along its own axis and can be buckled with the clamping member. The inner bracket can be buckled with the outer bracket selectively through the clamping member and the linkage hole. Disconnect the connection.

8. With the above technical scheme, the clamping piece and the linkage hole are matched, on the one hand, the outer bracket and the inner bracket can be connected and fixed, which ensures the receiving function of the shell, and on the other hand, the clamping piece and the linkage hole are detachable The connection structure form, when the overall height of the shell needs to be adjusted, it can be realized by applying force in the direction perpendicular to the axis of the inner bracket to prompt the clip to exit the linkage hole. It is convenient to operate, saves time and effort, and improves the overall fuel pump Adaptability, suitable for installation of multiple specifications and types of fuel tanks.

9. The above-mentioned telescopic and adjustable fuel pump casing assembly can be further configured as: the clamping member includes a connecting arm whose one end is fixedly connected to the inner bracket and whose axes are parallel to each other, and a butt fixedly connected to the other end of the connecting arm. An arm, the abutting arm extends toward the outer periphery of the inner bracket relative to the other end of the fixed connection arm.

10. With the above technical solution, since the direction of the interaction force between the inner stent and the outer stent is mainly the axial direction of the two, the abutment arm perpendicular to the axis of the inner stent is provided to block the force in the direction perpendicular to the axis of the inner stent. , To ensure the tightness of the connection between the inner stent and the outer stent, and prevent loosening.

11. The above-mentioned telescopic and adjustable fuel pump casing assembly can be further configured as follows: a quick release arm is provided between the abutting arm and the connecting arm, and both ends of the quick release arm are respectively connected to the abutting arm and The arm is relatively fixed.

12. With the above technical solution, the quick release arm mainly plays two roles. One is that the quick release arm forms an inclined surface to facilitate the removal of both the inner bracket and the outer bracket. When the overall height of the housing needs to be adjusted, the direction is perpendicular to the inner bracket. The force is applied in the axial direction. Under the action of the inclined surface of the quick release arm, it can be quickly withdrawn and easy to disassemble. Since the direction of the interaction force between the inner bracket and the outer bracket is mainly in the axial direction of the two, the disassembly force is related to the inner bracket and the outer bracket. The two anti-loosening will not affect each other; second, the quick release arm acts as a reinforcing rib, delaying the deformation of the clamping part, and thus prolonging the service life of the inner bracket.

13. The aforementioned casing assembly for a telescopic adjustable fuel pump can be further configured as follows: the inner bracket is provided with a counterweight groove on the outer periphery of the clamping member.

14. By adopting the above technical scheme, the counterweight groove can reduce the weight of the inner bracket, thereby reducing the overall weight of the fuel pump, which is in line with the concept of automobile lightweight.

15. The aforementioned casing assembly for a telescopic and adjustable fuel pump can be further configured as: the top cover and the outer bracket are both integrally formed.

16. The use of the above technical solutions reduces the processing and assembly procedures, which is conducive to reducing production man-hours
