[0001] This utility model relates to the field of automobile trailer hitch technology, specifically to an automobile trailer hitch installation device. Background Technology

[0002] A car tow hook is an important towing device for automobiles, used to tow trailers such as caravans, motorboat trailers, and storage boxes. It can be installed on the front or rear of a car and is mainly used for towing and rescuing other vehicles, especially providing assistance when off-roading.

[0003] However, existing car trailer hitch installation devices typically require a screwdriver to remove the trailer cover from the car. However, if the screwdriver is lost, the trailer cover is difficult to remove from the car. In addition, the car trailer hitch body is relatively small, which limits its rotation during installation and affects the installation efficiency. Therefore, a new car trailer hitch installation device is proposed. Utility Model Content

[0004] The main purpose of this utility model is to provide a car trailer hitch installation device. This utility model solves the problem of low installation efficiency of existing car trailer hitch installation devices by setting up a drive frame, limit rod, fixing block, lead screw, bracket, fixing plate and threaded sleeve.

[0005] The technical solution adopted by this utility model to solve its technical problem is a car trailer hook installation device, including a car trailer hook body and a drive frame. A throttle handle for providing power is inserted into the outside of the drive frame. A lead screw is fixed to one side of the throttle handle, and a threaded sleeve is threadedly connected to the outside of the lead screw. A laterally movable fixing block is welded to the outside of the threaded sleeve. A limiting rod for fixing the car trailer hook body is welded to the outside of the fixing block. A bracket is welded to the side of the threaded sleeve away from the fixing block, and a fixing plate is welded to the end of the bracket away from the threaded sleeve.

[0006] By adopting the above technical solution, when installing the car trailer hook body, first place the car trailer hook body inside the drive frame, turn the throttle outside the drive frame, the throttle drives the lead screw inside the drive frame to rotate, the threaded sleeve outside the lead screw moves laterally outside the lead screw under the action of the external limiting structure, and then the fixing block outside the threaded sleeve drives the limiting rod into the inside of the car trailer hook body, thereby facilitating the fixing of the car trailer hook body. Then, after the car trailer hook body is placed in the installation position on the car, the throttle drives the drive frame to rotate, the drive frame drives the car trailer hook body to rotate, so that the car trailer hook body enters the car, thereby improving the installation efficiency of the car trailer hook body.

[0007] When the threaded sleeve drives the limiting rod on the fixing block to fix the main body of the car trailer hook, the bracket on the outside of the threaded sleeve drives the fixing plate to move, so that the fixing plate moves to the outside of the drive frame, and then the fixing plate contacts the trailer cover on the car, thereby improving the efficiency of separating the trailer cover from the car.

[0008] Specifically, the inner side of the drive frame is provided with a fixing hole for limiting the position of the limiting rod.

[0009] By adopting the above technical solution, when the limiting rod enters the inner side of the car trailer hook body, one end of the limiting rod enters the fixing hole opened on the inner side of the drive frame, so that the limiting rod is fixed and the stability of the car trailer hook body is improved.

[0010] Specifically, the bracket is symmetrically screwed with rings on the outside, and a fixing rod is slidably connected to the inside of the rings.

[0011] By adopting the above technical solution, when the bracket moves the fixing plate, the outer ring of the bracket slides outside the fixing rod, thereby improving the stability of the bracket's movement.

[0012] Specifically, the inner dimensions of the fixing hole match the outer dimensions of the limiting rod.

[0013] By adopting the above technical solution, when the limiting rod enters the fixing hole, the inner dimension of the fixing hole matches the outer dimension of the limiting rod, which facilitates the fixing of the limiting rod.

[0014] Specifically, the external screws of the throttle are fixed with a rubber sleeve to improve the friction of the throttle surface.

[0015] By adopting the above technical solution, when the throttle is to be turned, the rubber sleeve on the outside of the throttle increases the friction on the surface of the throttle, making it easier for the throttle to rotate.

[0016] The beneficial effects of this utility model are:

[0017] (1) The automobile trailer hook installation device of this utility model, when installing the automobile trailer hook body, first put the automobile trailer hook body into the inside of the drive frame, turn the handle outside the drive frame, the handle drives the lead screw inside the drive frame to rotate, the threaded sleeve outside the lead screw moves laterally outside the lead screw under the action of the external limiting structure, and then the fixing block outside the threaded sleeve drives the limiting rod into the inside of the automobile trailer hook body, so as to facilitate the fixing of the automobile trailer hook body.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] To improve the installation efficiency of the car trailer hitch body 1, as one embodiment of this utility model, such as Figure 1 , Figure 2 As shown, the present invention provides a car trailer hook installation device, including a car trailer hook body 1 and a drive frame 2. A throttle 7 for providing power is inserted into the outside of the drive frame 2. A lead screw 12 is screwed to one side of the throttle 7, and a threaded sleeve 13 is threaded to the outside of the lead screw 12. A laterally movable fixing block 10 is welded to the outside of the threaded sleeve 13. A limiting rod 8 for fixing the car trailer hook body 1 is welded to the outside of the fixing block 10. A bracket 6 is welded to the side of the threaded sleeve 13 away from the fixing block 10, and a fixing piece 3 is welded to the end of the bracket 6 away from the threaded sleeve 13.

[0025] When installing the car trailer hook body 1, first place the car trailer hook body 1 inside the drive frame 2, rotate the handle 7 outside the drive frame 2, the handle 7 drives the lead screw 12 inside the drive frame 2 to rotate, the threaded sleeve 13 outside the lead screw 12 moves laterally outside the lead screw 12 under the action of the external limiting structure, and then the fixing block 10 outside the threaded sleeve 13 drives the limiting rod 8 into the car trailer hook body 1, so as to facilitate fixing the car trailer hook body 1. Then, after the car trailer hook body 1 is placed in the installation position on the car, the handle 7 drives the drive frame 2 to rotate, the drive frame 2 drives the car trailer hook body 1 to rotate, so that the car trailer hook body 1 enters the car, thereby improving the installation efficiency of the car trailer hook body 1.

[0026] When the threaded sleeve 13 drives the limiting rod 8 on the fixing block 10 to fix the car trailer hook body 1, the bracket 6 on the outside of the threaded sleeve 13 drives the fixing plate 3 to move, so that the fixing plate 3 moves to the outside of the drive frame 2, and then the fixing plate 3 contacts the trailer cover on the car, thereby improving the efficiency of separating the trailer cover from the car.

[0027] To improve the stability of the trailer hitch body 1, for example, such as Figure 1 , Figure 2 As shown, the present invention also includes a fixing hole 11 on the inner side of the drive frame 2 for limiting the position of the limiting rod 8.

[0028] When in use, after the limiting rod 8 enters the inner side of the car trailer hook body 1, one end of the limiting rod 8 enters the fixing hole 11 opened on the inner side of the drive frame 2, so that the limiting rod 8 is fixed and the stability of the car trailer hook body 1 is improved.

[0030] When in use, when the bracket 6 moves the fixing plate 3, the outer ring 4 of the bracket 6 slides outside the fixing rod 5, which improves the stability of the movement of the bracket 6.

[0031] To facilitate the fixing of the limiting rod 8, for example, as shown... Figure 2 As shown, the present invention also includes a fixing hole 11 whose inner dimensions match the outer dimensions of the limiting rod 8.

[0032] When in use, when the limiting rod 8 enters the fixing hole 11, the inner dimension of the fixing hole 11 matches the outer dimension of the limiting rod 8, which facilitates the fixing of the limiting rod 8.

[0033] To facilitate the rotation of the throttle 7, for example, as follows: Figure 1As shown, the present invention also includes a rubber sleeve 9 for improving the surface friction of the throttle 7, which is fixed to the external screw of the throttle 7.

[0034] When in use, when the throttle 7 is to be turned, the rubber sleeve 9 on the outside of the throttle 7 increases the friction on the surface of the throttle 7, making it easier for the throttle 7 to rotate.

[0035] When using this utility model, when installing the car trailer hook body 1, first place the car trailer hook body 1 inside the drive frame 2, rotate the handle 7 outside the drive frame 2. A bearing sleeve is provided at the connection between the handle 7 and the drive frame 2 to make the handle 7 rotate stably. The handle 7 drives the lead screw 12 inside the drive frame 2 to rotate. A bearing seat is provided at the connection between the lead screw 12 and the inside of the drive frame 2 to make the lead screw 12 rotate stably. The threaded sleeve 13 outside the lead screw 12 moves laterally outside the lead screw 12 under the action of the external limiting structure. Then, the fixing block 10 outside the threaded sleeve 13 drives the limiting rod 8 into the inside of the car trailer hook body 1, thereby facilitating the fixing of the car trailer hook body 1. After the car trailer hook body 1 is placed in the installation position on the car, the handle 7 drives the drive frame 2 to rotate, and the drive frame 2 drives the car trailer hook body 1 to rotate, so that the car trailer hook body 1 enters the car, thereby improving the installation efficiency of the car trailer hook body 1.

[0036] When the threaded sleeve 13 drives the limiting rod 8 on the fixing block 10 to fix the car trailer hook body 1, the bracket 6 on the outside of the threaded sleeve 13 drives the fixing plate 3 to move, so that the fixing plate 3 moves to the outside of the drive frame 2, and then the fixing plate 3 contacts the trailer cover on the car, thereby improving the efficiency of separating the trailer cover from the car.

[0037] When the limiting rod 8 enters the inner side of the car trailer hook body 1, one end of the limiting rod 8 enters the fixing hole 11 opened on the inner side of the drive frame 2, so that the limiting rod 8 is fixed and the stability of the car trailer hook body 1 is improved.

[0038] When the bracket 6 moves the fixing plate 3, the outer ring 4 of the bracket 6 slides outside the fixing rod 5, which improves the stability of the movement of the bracket 6.

[0039] When the throttle 7 is to be turned, the rubber sleeve 9 on the outside of the throttle 7 increases the friction on the surface of the throttle 7, making it easier for the throttle 7 to be turned.
