Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution: an accelerator auxiliary mounting structure, including an outer shell 1, a mounting member 2, a fixing rod 3, and a limit pin 4. Through grooves 12 are respectively formed in the middle parts of both sides of the outer shell 1. Threaded locking nuts 31 are installed at both ends of the fixing rod 3 outside the outer shell 1. The mounting member 2 includes symmetrically arranged mounting bases 21;

[0022] Positioning rods 22 are fixedly penetrated through one side of the tops of the two groups of mounting bases 21. Positioning balls 24 are respectively arranged at both ends of the positioning rods 22. The two groups of positioning balls 24 respectively extend into the inner side walls of the guiding grooves 12 on the same side. Rotating plates 5 are respectively rotatably installed on both sides of the outer shell 1. An inserting rod 41 is fixedly installed on the side of the limit pin 4 close to the rotating plate 5. The other end of the inserting rod 41 is fixedly connected to the mounting base 21 on the same side;

[0023] The mounting base 21 in the mounting member 2 is matched by a magnet on the side. After the mounting member 2 and the corresponding limit pin 4 on the outside are assembled, by rotating the limit pin 4, the positioning rod 22 in the mounting member 2 can slide along the guiding groove 12. And under the cooperation of the external spring and the top fixing rod 3, the mounting base 21 can make the rotation speed of the limit pin 4 uniform. The mounting member 2 and the limit pin 4 are used in cooperation to control the accelerator, which is a prior art solution and will not be elaborated here;

[0024] In the mounting member 2, two sets of mounting seats 21 are connected through the positioning rod 22 passing through. The positioning rod 22 can slide from the auxiliary chute 11 into the corresponding guiding chute 12. Under the elastic cooperation of the positioning spring 25, the positioning ball 24 at the end of the positioning rod 22 can enter the inner arc chamfer 13 of the guiding chute 12 to position the positioning rod 22. At this time, by touching the limit pin 4, the insertion rod 41 at one end of the limit pin 4 can be inserted into the mounting hole on the corresponding rotating plate 5 and inserted and fixed with the second through groove 26 on the side of the mounting seat 21. In this way, it is realized that the mounting member 2 can be assembled with the housing 1 as a whole, and can be quickly positioned corresponding to the corresponding limit pin 4 after assembly, realizing the convenience of disassembling and assembling the mounting member 2.

[0025] Among them, auxiliary chutes 11 are respectively opened on both sides of the inner wall of the housing 1. The auxiliary chutes 11 communicate with the guiding chutes 12 on the same side. An arc chamfer 13 is provided at the edge of the inner side surface of the guiding chute 12. When the end of the positioning rod 22 slides from the auxiliary chute 11 into the guiding chute 12, under the elastic cooperation of the positioning spring 25, the positioning ball 24 at the end of the positioning rod 22 can enter the inner arc chamfer 13 of the guiding chute 12 to position the positioning rod 22.

[0026] Among them, the end of the fixing rod 3 movably passes through the inner wall of the auxiliary chute 11 on the same side and extends to the outside of the housing 1. By disassembling the locking nut 31 at the end of the fixing rod 3, the fixing rod 3 can be disassembled from the top of the housing 1. In this way, the positioning of the return spring in the mounting member 2 can be released, and at the same time, the mounting member 2 can be integrally slid out from the auxiliary chute 11.

[0027] Among them, a first through groove 23 is penetrated and opened on the outside of the mounting seat 21. The end of the positioning rod 22 extends into the inner wall of the first through groove 23 on the same side. A positioning spring 25 is fixedly connected to the end of the inner wall of the positioning rod 22. The positioning ball 24 is fixedly connected to the positioning spring 25 away from the end of the positioning rod 22. When the end of the positioning rod 22 slides from the auxiliary chute 11 into the guiding chute 12, under the elastic cooperation of the positioning spring 25, the positioning ball 24 at the end of the positioning rod 22 can enter the inner arc chamfer 13 of the guiding chute 12 to position the positioning rod 22.

[0028] Among them, a second through groove 26 matching the insertion rod 41 is opened on one side of the mounting seat 21. The insertion rod 41 is fixedly inserted into the inner wall of the second through groove 26 through the fixed rotating plate 5. Under the elastic cooperation of the positioning spring 25, the positioning ball 24 at the end of the positioning rod 22 can enter the inner arc chamfer 13 of the guiding chute 12 to position the positioning rod 22. At this time, the limit pin 4 can correspond to the second through groove 26 on the side of the corresponding mounting seat 21. By touching the limit pin 4, the insertion rod 41 at one end of the limit pin 4 can be inserted into the mounting hole on the corresponding rotating plate 5 and inserted and fixed with the second through groove 26 on the side of the mounting seat 21.

[0029] Working principle: When assembling the mounting member 2 and the mounting housing 1 in the accelerator, firstly, the two sets of mounting seats 21 in the mounting member 2 are fixed and penetrated through the positioning rod 22, and the positioning rod 22 can slide from the auxiliary slide groove 11 to the corresponding guide groove 12. The positioning ball 24 at the end of the positioning rod 22 can enter the inner arc chamfer 13 of the guide groove 12 to position the positioning rod 22 under the elastic cooperation of the positioning spring 25;

[0030] Then, by abutting against the limit pin 4, the insertion rod 41 at one end of the limit pin 4 can be inserted into the corresponding mounting hole on the rotating plate 5 and the second through slot 26 on the side of the mounting seat 21 for fixing, so that the mounting member 2 can be assembled with the housing 1 as a whole, and can be quickly positioned with the corresponding limit pin 4 after assembly, so that the mounting member 2 can be conveniently disassembled and assembled;

[0031] Finally, the end of the fixing rod 3 is movable through the inner wall of the auxiliary slide groove 11 on the same side to extend to the outside of the outer shell 1, and the two ends of the fixing rod 3 are locked on the outer shell 1 with locking nuts 31. By pressing one end of the return spring on the mounting seat 21 against the outside of the fixing rod 3, the mounting part 2 in the accelerator and the outer shell 1 can be assembled.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments without departing from the principles of the present invention.
