Description

Technical Field

[0001] This utility model relates to the field of truck support rod technology, and in particular to a novel truck support rod handle. Background Technology

[0002] In the loading and securing of cargo on trucks, cargo spreaders are crucial devices for ensuring cargo stability and preventing displacement during transportation. The cargo spreader handle, as its core operating component, directly impacts the efficiency and reliability of the cargo-supporting operation. Existing technologies, such as the cargo spreader handle proposed in Chinese Patent No. "CN202279038U," employ a design with teeth on both sides of the handle's rotating connection end. The intention is to achieve outward extension of the rack and tube through the meshing of these teeth with the rack on the support rod, thereby completing the cargo support and securing action.

[0003] However, this traditional structure with teeth on both sides of the handle has a limited stress-bearing area and weak structural strength during use. During truck transportation, road bumps and cargo shaking will cause the handle to be frequently stressed. The teeth will be subjected to alternating loads for a long time, which will easily lead to the failure of the teeth and rack meshing, resulting in the inability to effectively secure the cargo. At the same time, under continuous stress, the teeth will also bend and deform due to stress concentration. In severe cases, the entire handle will lose its driving function and must be scrapped. Therefore, we have proposed a new type of truck support rod handle to solve the above problems. Utility Model Content

[0004] This invention addresses the defect in existing technology where the teeth at the end of the handle are prone to failure in meshing with the rack during long-term use, and provides a new type of truck support rod handle.

[0005] This utility model is achieved through the following technical solution:

[0006] A novel truck support rod handle includes a handle body with a locking plate on one side and a hinge at one end. The hinge contains multiple parallel actuating plates, each with fan-shaped teeth protruding from the outer end of the hinge. The multiple actuating plates are mounted in the hinge via a mounting shaft, which has a through hole in the middle to provide mounting space for a pin during handle body assembly.

[0007] In a preferred embodiment of this utility model, the number of the toggle pieces is two to five, and a through hole is provided in the middle of the toggle piece. The mounting shaft is inserted into the through hole, and all the toggle pieces are fixedly installed by the mounting shaft.

[0008] In a preferred embodiment of this utility model, the hinge portion is provided with mounting holes, and both ends of the mounting shaft are fixed in the mounting holes to provide mounting positions for the actuating piece.

[0009] In a preferred embodiment of the present invention, a limiting boss is provided on the inner side of the hinge portion, and a limiting groove adapted to the limiting boss is provided on the actuating piece. The stability of the actuating piece between the hinge portion is ensured by the cooperation between the limiting boss and the limiting groove.

[0010] In a preferred embodiment of this utility model, a downward-facing flange is provided at the edge of the handle body, and a cavity is formed between the flange and the handle body to ensure the strength of the handle.

[0011] In a preferred embodiment of the present invention, the locking plate is located at the bottom of one side flange, and the locking plate, flange and handle body are integrally stamped.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model replaces the traditional two-sided toothed structure with multiple parallel actuating plates, which greatly improves the overall strength of the handle drive end, reduces failure problems such as stripping and bending, and extends the service life of the handle.

[0014] 2. In this utility model, when the toggle piece is damaged, it is not necessary to replace the entire handle; only the damaged toggle piece needs to be replaced, thus reducing maintenance and usage costs. Attached Figure Description

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0021] Example 1:

[0022] like Figure 1-2 The present invention relates to a novel truck support handle, comprising a handle body 1. To enhance the overall structural strength of the handle, a downwardly extending flange structure is provided at the edge of the handle body 1. The flange and the handle body 1 naturally enclose to form a concave cavity. By increasing the structural thickness and stress support surface at the edge of the handle body 1, the flange structure can effectively disperse the external force applied during hand operation, prevent the handle body 1 from deforming or breaking due to local stress concentration, and significantly improve the strength and durability of the handle under long-term repeated operation and the complex working conditions of truck operation, thus ensuring the stability of the handle structure.

[0023] Among them, a locking plate 2 is provided on one side of the handle body 1, which is used to fit and lock with the relevant structure of the truck support rod. The locking plate 2 is located at the bottom of the flange on one side. The locking plate 2, the flange and the handle body 1 are integrally stamped.

[0024] One end of the handle body 1 extends into a hinge part 3. The drive end of the hinge part 3 handle has two to five actuating plates 4 arranged in parallel inside. The number of actuating plates 4 can be adjusted according to the torque and strength requirements of the truck support rod to adapt to trucks of different tonnages. At the same time, the outer end of the actuating plate 4 is provided with teeth arranged in a fan shape. The teeth protrude from the outer end of the hinge part 3. Through the cooperation of the teeth and the external rack, a progressive drive is achieved when the handle is turned, making the rack extension action smoother.

[0025] The center of the actuating piece 4 has a through hole 41, and multiple actuating pieces 4 are integrated and assembled in the hinge part 3 via a mounting shaft 5. The mounting shaft 5 is inserted into the through hole 41, and a through hole 51 is provided in the center of the mounting shaft 5. The hinge part 3 has a mounting hole 31, and both ends of the mounting shaft 5 are fixed in the mounting hole 31 to provide a mounting position for the actuating pieces 4. The through hole 51 provides axial mounting space for the mounting pin of the handle body 1. When the handle is systematically assembled with the truck support rod, the pin can pass through the through hole 51 to connect with the external structure, which not only ensures the flexibility of the handle rotation around the pin, but also prevents axial movement of the mounting shaft 5 and the actuating pieces 4 through the radial limit of the pin, making the drive structure more stable.

[0026] Secondly, to further improve the installation stability of the toggle piece 4 in the hinge part 3, a limiting boss 32 is provided on the inner side of the hinge part 3, and a limiting groove 42 that matches the limiting boss 32 is provided on the toggle piece 4. The inner end face of the limiting groove 42 is "U" shaped. When assembling, the limiting boss 32 is precisely inserted into the limiting groove 42 to form a limiting structure. The cooperation between the limiting boss 32 and the limiting groove 42 ensures the stability of the toggle piece 4 in the hinge part 3 and prevents the toggle piece 4 from shaking in the hinge part 3 when using the handle body 1. In order to fix the toggle piece 4 in the hinge part 3, a pin can also be used for fixing.

[0027] Example 2:

[0028] like Figure 2-4 As shown, while ensuring the strength of the hinge part 3, in order to reduce the number of actuating pieces 4, teeth with the same shape as the outer end of the actuating piece 4 can be directly provided on the outer end of the hinge part 3. In this way, the existing handle can be directly modified without reproducing the handle body 1. The other structures are the same as those in Embodiment 1.

[0029] In this embodiment, by arranging multiple actuating plates 4 in parallel in the hinge part 3, the overall strength of the handle drive end is greatly improved, the failure problems such as stripping and bending are reduced, and the service life of the handle is extended.

[0030] It should be noted that, in the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "setting," "provided with," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
