[0026] like Figure 1 and Figure 3 As shown in the figure, an embodiment of this application provides a hood anti-fall support rod fixture for installation between a hood and a hood that are arranged vertically opposite each other. The fixture includes a connecting shaft 1 and an anti-opening hook 2. The anti-opening hook 2 is connected to the side wall of the connecting shaft 1. A first locking pin 3 is provided at the top of the connecting shaft 1. The first hooking part 32 of the first locking pin 3 passes through the sheet metal hole of the inner plate of the hood and hooks onto the back of the sheet metal of the inner plate of the hood. A second locking pin 4 is provided at the bottom of the connecting shaft 1. The second locking pin 4 is inserted into the top of the front crossbeam of the hood. The second hooking part 21 at the bottom of the anti-opening hook 2 hooks onto the side of the front crossbeam.
[0027] In conjunction with the above embodiments, the tooling includes a connecting shaft 1 and an anti-opening hook 2. When the tooling supports the machine cover, the connecting shaft 1 and the anti-opening hook 2 are located between the machine cover and the machine compartment, respectively. The two ends of the connecting shaft 1 extend vertically or slightly inclined. A first locking pin 3 is provided at the top of the connecting shaft 1, and a first hooking part 32 is provided at the top of the first locking pin 3. The first hooking part 32 is used to pass through the sheet metal hole of the machine cover and hook onto the back of the sheet metal, thereby hooking with the sheet metal of the machine cover through the first locking pin 3. For example, the overall shape of the first hooking part 32 can be an inverted "L" shape. A second locking pin 4 is provided at the bottom of the connecting shaft 1, and the bottom of the second locking pin 4 is inserted into the top surface of the front crossbeam of the machine compartment. In addition, the top of the anti-opening hook 2 is connected to the side wall of the connecting shaft 1, and the second hooking part 21 at the bottom of the anti-opening hook 2 hooks onto the side of the front crossbeam of the machine compartment.
[0028] Furthermore, the anti-opening hook 2 is rod-shaped, and its axis forms an acute angle (e.g., 10°-15°) with the axis of the connecting shaft 1. Through the three-point support provided by the connecting shaft 1 and the anti-opening hook 2 between the hood and the engine compartment, and with the connecting shaft 1 hooked to the back of the sheet metal via the first hook part 32, and the anti-opening hook 2 hooked to the side of the front crossbeam via the second hook part 32, the hood can effectively resist vibrations generated during painting or vehicle operation, thus providing stable support and effectively preventing the risk of the hood detaching during painting or vehicle operation.
[0029] Furthermore, the anti-opening hook 2 can generally be positioned at any height on the side wall of the connecting shaft 1, for example, the top of the anti-opening hook 2 can be connected to the side wall in the middle of the connecting shaft 1. In practice, placing the anti-opening hook 2 in the middle or higher of the connecting shaft 1 often results in the anti-opening hook 2 being too long, which may hinder the application of adhesive to the sheet metal inside the cover. Therefore, as a preferred embodiment, the anti-opening hook 2 is preferably positioned on the side wall of the connecting shaft 1 near its bottom end. For example, the distance from the top of the anti-opening hook 2 to the bottom end of the connecting shaft 1 is approximately one-fifth of the total length of the connecting shaft 1. In this way, the anti-opening hook 2 is in a lower position and will not hinder the application of adhesive to the sheet metal inside the cover.
[0030] The hood anti-fall support rod tooling of this application embodiment includes a first limiting part 31 for the first locking pin 3. The first limiting part 31 is connected to the top end of the connecting shaft 1 and the first hook part 32 respectively. The minimum size of the first limiting part 31 is larger than the diameter of the sheet metal hole, and is used to abut against the front of the sheet metal after the first hook part 32 passes through the sheet metal hole.
[0031] In conjunction with the above embodiments, the first limiting part 31 serves two purposes: firstly, it connects the top end of the connecting shaft 1 and the bottom end of the first hook part 32; secondly, it serves as a limiting part. Since the minimum size of the first limiting part 31 is larger than the inner diameter of the sheet metal hole, for example, if the first limiting part 31 is disc-shaped and its diameter is slightly larger than the inner diameter of the sheet metal hole, after the first hook part 32 is inserted into the cover to a certain depth through the sheet metal hole, the first limiting part 31 abuts against the front of the sheet metal, and at the same time, the first hook part 32 can also hook onto the back of the sheet metal.
[0032] The hood anti-fall support rod fixture of this application embodiment has a first connecting hole and a second connecting hole respectively provided on the top surface and side surface of the front crossbeam. The second locking pin 4 is inserted into the first connecting hole, and the second hook part 21 extends into the second connecting hole and hooks onto the inner side of the front crossbeam.
[0033] In conjunction with the above embodiments, the second locking pin 4 and the second hooking part 21 are used to connect with the front crossbeam of the cabin. The front crossbeam of the cabin is generally hollow and elongated, and the top surface and side surface of the front crossbeam are respectively provided with a first connecting hole and a second connecting hole. The bottom of the second locking pin 4 is inserted into the interior of the front crossbeam through the first connecting hole. The second hooking part of the anti-opening hook 2 is generally L-shaped, and the second hooking part 21 passes through the second connecting hole and hooks onto the inside of the front crossbeam.
[0034] In this embodiment of the hood anti-fall support rod fixture, the second locking pin 4 also includes a second limiting part 41 and a plug-in part 42. The second limiting part 41 is connected to the bottom end of the connecting shaft 1 and the plug-in part 42 respectively. The plug-in part 42 is used to extend into the first connecting hole. The minimum size of the second limiting part 41 is larger than the diameter of the first connecting hole, so that after the plug-in part 42 extends into the first connecting hole, it abuts against the top surface of the front crossbeam.
[0035] In conjunction with the above embodiments, the second limiting part 41 serves two purposes: firstly, it connects the bottom end of the connecting shaft 1 and the top end of the insertion part 42; secondly, it serves a limiting function. Since the minimum size of the second limiting part 41 is larger than the inner diameter of the first connecting hole, for example, if the second limiting part 41 is disc-shaped and its diameter is slightly larger than the inner diameter of the first connecting hole, after the insertion part 42 is inserted into the front crossbeam to a certain depth through the first connecting hole, the second limiting part 41 abuts against the top surface of the front crossbeam.
[0036] The anti-fall support rod fixture for the hood in this embodiment has an anti-opening hook 2 with an inverted "L" shape at the top. A nut 5 is provided on the side wall of the connecting shaft 1, and an external thread is provided on the outer side wall of the top of the anti-opening hook 2. The anti-opening hook 2 is threadedly connected to the nut 5 through the external thread. The top of the anti-opening hook 2 is connected to the connecting shaft 1 through a threaded connection. After the connecting shaft 1 is assembled with the hood and the hood respectively, the anti-opening hook 2 can be quickly installed by rotating it at a certain angle and adjusting the tilt angle of the anti-opening hook 2.
[0037] The hood anti-fall support rod tooling of this application embodiment is provided with an ear-shaped handle 6 on the side wall of the connecting shaft 1. The handle 6 makes it easy for the operator to hold the connecting shaft 1, and facilitates the installation or disassembly of the connecting shaft 1.
[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
