A movable rod extends into the sliding groove, and one end of the movable rod extending into the sliding groove is provided with a connecting block extending upward from the stroke hole. The connecting block is connected to the pull handle. After the pull handle is pulled, the movable rod moves towards the fixed rod side in the sliding groove.

[0008] The connecting block is connected to the pull handle via a connecting screw.

[0009] The stroke adjustment mechanism consists of a first screw fixed on the connecting block, a second screw fixed on the pull handle, and a sleeve connecting the first screw and the second screw. After rotating the sleeve, the first screw and the second screw can move relative to each other.

[0010] The fixing box includes an upper top plate and a lower bottom plate, and a sliding groove is formed between the upper top plate and the lower bottom plate.

[0011] The pull handle includes a base fixed to the top plate and a handle hinged to the base, with one bottom end of the handle fixedly connected to the second screw.

[0012] The connecting mechanism is a positioning pin fixed to the outward end of the fixed rod and the movable rod.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not constitute a limitation thereof.

[0026] This invention provides a mounting device for the upper crossbeam of an automotive water tank, such as... Figure 1-2 As shown, it includes a movable rod 20, a fixed rod 10, and a clamping mechanism. The clamping mechanism movably connects the movable rod 20 and the fixed rod 10 together and keeps them in a straight line. The outward-facing ends of the movable rod 20 and the fixed rod 10 are provided with a connecting mechanism that connects to the crossbeam on the water tank. The clamping mechanism can make the movable rod 20 move a certain distance relative to the fixed rod 10 and then remain fixed.

[0027] Specifically, the clamping mechanism includes a fixed box and a pull handle 33 located on the fixed box. In this embodiment, the fixed box consists of an upper top plate 32 and a lower bottom plate 31. One end of the fixed box is fixedly connected to the fixed rod 10, and the other end of the fixed box is provided with a sliding groove 37 located inside the fixed box. The sliding groove 37 has a stroke hole 35 on the upper surface of the fixed box. A movable rod 20 extends into the sliding groove 37. One end of the movable rod 20 that extends into the sliding groove 37 is provided with a connecting block 21 that extends upward from the stroke hole 35. The connecting block 21 is connected to the pull handle 33. After pulling the pull handle 33, the movable rod 20 moves towards the fixed rod 10 in the sliding groove 37, thereby causing the connecting mechanism located at the outer ends of the movable rod 20 and the fixed rod 10 to move towards each other, thereby achieving clamping.

[0028] Preferably, the connecting block 21 is connected to the pull handle 33 via the connecting screw 34.

[0029] To ensure the water tank's upper beam mounting device is adaptable to different vehicle models, the clamping mechanism also includes a stroke adjustment mechanism. This mechanism adjusts the movement distance of the movable rod 20 relative to the fixed rod 10. Specifically, the stroke adjustment mechanism divides the connecting screw 34 into two sections: a first screw and a second screw. The first screw is fixedly connected to the connecting block 21, and the second screw is fixedly connected to the pull handle 33. The opposite ends of the first and second screws are connected by a sleeve. Thus, rotating the sleeve allows relative movement between the first and second screws, thereby changing the distance 'a' between the connecting block 21 and the pull handle 33. Preferably, 'a' is 30mm. Alternatively, the stroke adjustment mechanism can also be configured with sleeves at both ends and a screw in the middle. Figure 1 , Figure 2This is the case here. For those skilled in the art, this solution is easily understood based on the solution of the first screw, the second screw, and the sleeve, and will not be elaborated further here.

[0030] The pull handle includes a base fixed to the upper top plate 32 and a handle hinged to the base, with one bottom end of the handle fixedly connected to the connecting screw 34 or the second screw.

[0031] The aforementioned connecting mechanism consists of a positioning pin 40 fixed to the outward-facing end of the fixed rod 10 and the movable rod 20. The positioning pin 40 extends downwards and connects to the upper crossbeam of the headlight by inserting into a positioning hole on the upper crossbeam. In use, as follows... Figure 3 As shown, insert the positioning pin 40 into the positioning hole of the upper crossbeam 2 of the headlight, close the pull handle 33, and the movable rod 20 moves inwards towards each other, reducing the size of the engine compartment opening. Align the upper crossbeam 2 of the radiator with the installation position, tighten the bolts, and after assembly, open the pull handle 33 to remove the upper crossbeam mounting device 1, completing the entire installation process. When switching between different vehicle models, adjusting the stroke adjustment mechanism can meet the requirements.

[0032] The above detailed embodiments describe the basic principles and main features of the present invention. Those skilled in the art should understand that the scope of protection of the present invention is not limited to the above embodiments, and any variations or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
