[0018] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0019] Reference Figure 1-4 As shown, a novel automotive flanged bushing comprises a connecting member 1 and a bushing body 3 arranged on one side of the connecting member 1, and a fixing member 2 detachably connected to the connecting member 1 is fixed to one end of the bushing body 3 facing the connecting member 1;

[0020] Two positioning plugs 4 with cavities inside are symmetrically and vertically fixed on one surface of the fixing member 2 facing the connecting member 1. A socket adapted to the positioning plug 4 is provided on the connecting member 1. A control groove 8 connected to the inner cavity of the positioning plug 4 is provided in the inner wall of the fixing member 2. An elastic plug-in portion for locking the positioning plug 4 in the socket is provided in the positioning plug 4. A pressurizing portion for providing extrusion force to the elastic plug-in portion is provided in the control groove 8.

[0021] The elastic plug-in portion includes a pressure block 5 slidably arranged in the positioning plug block 4 and a positioning column 6 vertically fixed on one side of the pressure block 5. A through hole is provided on the outer wall of the positioning plug block 4, and the end of the positioning column 6 is inserted into the through hole. A fixing hole corresponding to the through hole is provided on the inner wall of the socket. Spring telescopic rods 7 are provided on both sides of the positioning column 6. The two ends of the spring telescopic rod 7 are respectively fixed to the pressure block 5 and the inner wall of the positioning plug block 4, and the other side of the pressure block 5 is inclined.

[0022] The booster part includes a positioning seat 10 vertically fixed between the inner walls of the two ends of the control groove 8 and an extrusion screw 9 threadedly penetrating the inner wall of the positioning seat 10. One end of the extrusion screw 9 is hemispherical and butted against the hypotenuse of the pressure block 5.

[0023] Through the arrangement of the positioning plug block 4, the elastic plug-in portion and the boosting portion, when the bushing body 3 is to be installed, the two positioning plug blocks 4 need to be aligned and inserted into the two sockets on the connecting member 1 when the fixing member 2 is fitted to the connecting member 1, and then the extrusion screw 9 in the boosting portion rotates, and the extrusion screw 9 can extend from the thread structure to the inside of the positioning plug block 4 during the rotation process and squeeze the inclined surface of the pressure block 5, so that the pressure block 5 is forced to carry the positioning column 6 to slide and compress the spring telescopic rod 7, so that the positioning column 6 can be inserted into the fixing hole through the perforation, and the positioning plug block 4 is locked in the socket, so as to achieve a fixed connection between the fixing member 2 and the connecting member 1;

[0024] On the contrary, the extrusion screw 9 rotates in the opposite direction, causing the extrusion screw 9 to shrink toward the inside of the control groove 8, reducing the extrusion on the pressure block 5. The pressure block 5 can then carry the positioning column 6 to quickly reset under the elastic force of the spring telescopic rod 7, allowing the positioning column 6 to withdraw from the fixing hole, thereby releasing the fixing effect of the positioning plug 4 in the socket.

[0025] Further, refer to Figure 1 , Figure 2 as well as Figure 4 As shown, it is worth noting that a power supply part for synchronously providing power to the two groups of boosting parts is provided on the outer side of the fixing member 2;

[0026] The force supply part includes a push-pull plate 14 slidably arranged on the outside of the fixing member 2 in an arc shape, and connecting rods 15 are fixed at both ends of the push-pull plate 14. A slideway 12 connected to the control groove 8 is opened on the outer wall of the fixing member 2. The end of the connecting rod 15 penetrates into the slideway 12 and is fixed with a tooth plate 13. The rod body at the other end of the extrusion screw 9 is fastened with a gear 11 meshing with the tooth plate 13.

[0027] Through the setting of the force supply part, by simply pushing and pulling the push-pull plate 14, the two tooth plates 13 can synchronously slide in the two control grooves 8 and mesh with the gears 11 on the two extrusion screws 9, providing synchronous rotational force for the two extrusion screws 9, so that the two extrusion screws 9 synchronously squeeze the elastic plug-in parts in the two positioning blocks 4, thereby achieving the synchronous fixing and disassembly effect of the two positioning blocks 4. Compared with the cumbersome fixing method of the fixing part 2 in the prior art, this can effectively omit the working steps, improve the working efficiency, and enhance the practicality.

[0028] Further, refer to Figure 1 and Figure 2 As shown, it is worth noting that a positioning screw 16 is vertically fixed on the outer wall of the fixing member 2, the end of the positioning screw 16 passes through the push-pull plate 14, and the end of the positioning screw 16 is also threadedly connected to a locking cap 17;

[0029] By setting the positioning screw 16 and the locking cap 17, after the push-pull plate 14 is pushed and pulled to complete the synchronous fixing effect of the two positioning plugs 4, the locking cap 17 is screwed into the end of the positioning screw 16 so that the locking cap 17 is pressed against the push-pull plate 14, and the push-pull plate 14 can be locked, thereby ensuring the stable meshing effect between the tooth plate 13 and the gear 11 and the extrusion effect of the extrusion screw 9 on the pressure block 5.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected.
