Description

Technical Field

[0001] This application relates to the field of pallet trucks, and more specifically, to a pallet truck chassis structure. Background Technology

[0002] Handling vehicles are widely used in logistics, warehousing and other fields. Among them, small handling carts are frequently used in warehouses. The small size of the handling carts makes them easy to move within the warehouse. However, existing handling carts lack guardrail structures. When products are placed on the chassis of the handling cart and the cart is pushed, especially when turning or stopping suddenly, the products are prone to tipping over due to inertia. To address this, we have proposed a new handling vehicle chassis structure. Utility Model Content

[0003] To overcome the above shortcomings, this application provides a transport vehicle chassis structure, which aims to improve the problem that the existing transport vehicle chassis structure cannot protect the product.

[0004] This application provides a transport vehicle chassis structure, including a chassis body. Two protective plates are inserted into the middle part of the chassis body. Positioning components are installed on both end side walls of the chassis body. After the two protective plates are pulled out from the chassis body, they are respectively inserted into the two positioning components. Mounting plates are connected to the front and rear sides of the top of the chassis body. Two locking members are installed on one of the mounting plates, and the two locking members are respectively inserted into the two protective plates.

[0005] In one specific implementation, the chassis body includes a top plate and a bottom plate, with two fixing blocks connected between the top plate and the bottom plate, forming a receiving cavity between the top plate, the bottom plate and the two fixing blocks, and the two protective plates stacked and inserted into the receiving cavity.

[0006] In one specific implementation, limiting members are fixedly installed on both ends of the base plate, and the two limiting members are respectively in contact with the two protective plates.

[0007] In one specific implementation, the limiting member includes a first mounting block, which is fixedly mounted on one side wall of the base plate. A first sliding rod slides through the first mounting block. A first connecting block is fixedly mounted at the bottom of the first sliding rod. A limiting block is fixedly mounted at the top of the first sliding rod. A first spring sleeved on the first sliding rod is connected between the first mounting block and the first connecting block. The limiting block is in contact with the protective plate.

[0008] In one specific implementation, the positioning component includes a support block, a positioning block is fixedly mounted on the top of the support block, and the protective plate can be inserted into the positioning block.

[0009] In one specific implementation, the protective plate is T-shaped, and the head of the protective plate has several positioning grooves, which are respectively fitted onto several positioning blocks.

[0010] In one specific implementation, the locking element includes a second mounting block, a second slide rod that slides through the second mounting block, a second connecting block that is fixedly mounted at one end of the second slide rod, and the other end of the second slide rod that is inserted into the protective plate. A second spring that is sleeved on the second slide rod is connected to the second mounting block and the second connecting block.

[0011] In one specific implementation, a set of rollers is installed at the bottom of the chassis body.

[0012] The beneficial effects of this application are as follows: By setting a top plate and a bottom plate, and fixing two blocks are fixedly connected between the top plate and the bottom plate, a receiving cavity is formed between the top plate, the bottom plate and the two fixing blocks, so that two protective plates are inserted into the receiving cavity from both sides, and the two protective plates are stacked in the receiving cavity. When the protective plates are needed, the protective plates are pulled out and inserted into the positioning components, and then the protective plates are fixed by the locking parts on the mounting plate, thus realizing the installation of the protective plates. The two protective plates cooperate with the two mounting plates to protect the products on the chassis body, and at the same time, it achieves the purpose of facilitating the installation and removal of the protective plates.

Detailed Implementation

[0016] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0017] Please see Figure 1-6 This application provides a transport vehicle chassis structure, including a chassis body 10. When installed, a roller assembly is mounted on the bottom of the chassis body 10 to drive its movement. Two protective plates 20 are inserted into the middle of the chassis body 10. Positioning components 30 are installed on both end sidewalls of the chassis body 10. After the two protective plates 20 are pulled out from the chassis body 10, they are respectively inserted into the two positioning components 30. Mounting plates 40 are connected to the front and rear sides of the top of the chassis body 10. Two locking elements 50 are installed on one of the mounting plates 40, and the two locking elements 50 are respectively inserted into the two protective plates 20. Specifically, after the protective plates 20 are pulled out, they are inserted into the positioning components 30 and fixed by the locking elements 50. Thus, the two protective plates 20 cooperate with the two mounting plates 40 to protect the product. After removing the protective plates 20, the product can be easily removed.

[0018] See Figure 3 The chassis body 10 includes a top plate 110 and a bottom plate 120. Two fixing blocks 130 are connected between the top plate 110 and the bottom plate 120. A receiving cavity 140 is formed between the top plate 110, the bottom plate 120 and the two fixing blocks 130. Two protective plates 20 are stacked and inserted into the receiving cavity 140. Limiting members 60 are fixedly installed on both side walls of the bottom plate 120. The two limiting members 60 are respectively in contact with the two protective plates 20. After the two protective plates 20 are inserted into the receiving cavity 140, the two limiting members 60 limit the protective plates 20 to prevent the protective plates 20 from falling out of the receiving cavity 140.

[0019] See Figure 5The limiting component 60 includes a first mounting block 610, which is fixedly mounted on one side wall of the base plate 120. A first sliding rod 620 slides through the first mounting block 610. A first connecting block 630 is fixedly mounted at the bottom of the first sliding rod 620. A limiting block 640 is fixedly mounted at the top of the first sliding rod 620. A first spring 650 sleeved on the first sliding rod 620 connects the first mounting block 610 and the first connecting block 630. The limiting block 640 is in contact with the protective plate 20. By pulling the first connecting block 630 downward, the first connecting block 630 pulls the limiting block 640 through the first sliding rod 620, causing the limiting block 640 to disengage from the protective plate 20, thereby releasing the limiting of the protective plate 20 and allowing the protective plate 20 to be pulled out from the receiving cavity 140.

[0020] See Figure 5 The positioning component 30 includes a support block 310, a positioning block 320 fixedly installed on the top of the support block 310, a protective plate 20 that can be inserted into the positioning block 320, the protective plate 20 is T-shaped, the head of the protective plate 20 is in sliding contact with the receiving cavity 140, the head of the protective plate 20 is provided with a plurality of positioning grooves 210, the plurality of positioning grooves 210 are respectively fitted on the plurality of positioning blocks 320, after the protective plate 20 is pulled out from the receiving cavity 140, the positioning grooves 210 on the protective plate 20 are inserted into the corresponding positioning blocks 320.

[0021] See Figure 6 The locking component 50 includes a second mounting block 510, a second slide rod 520 that slides through the second mounting block 510, a second connecting block 530 that is fixedly mounted on one end of the second slide rod 520, and the other end of the second slide rod 520 that is inserted into the protective plate 20. A second spring 540 that is sleeved on the second slide rod 520 is connected to the second mounting block 510 and the second connecting block 530. In a specific configuration, an insertion hole (not shown in the figure) is provided on the side wall of the protective plate 20. The insertion hole is correspondingly set with the second slide rod 520, so that one end of the second slide rod 520 can be inserted into the insertion hole to fix the protective plate 20.

[0022] When using this pallet truck chassis structure: Place the product on the chassis body 10, with the product positioned between the two mounting plates 40. Then, pull down the first connecting block 630, causing the first connecting block 630 to move the limiting block 640 downwards via the first sliding rod 620. This separates the limiting block 640 from the protective plate 20, allowing the protective plate 20 to be removed. After removing both protective plates 20, align the positioning groove 210 on the protective plate 20 with the positioning block 320, thus installing the protective plate 20 onto the support block 310. Before this, pull the second connecting block 530, causing it to move the second sliding rod 520. After installing the protective plate 20 onto the support block 310, the insertion hole on the protective plate 20 aligns with the second sliding rod 520, allowing the second sliding rod 520 to be inserted into the insertion hole, thus fixing the protective plate 20. After this, the chassis body 10 can be moved.

[0023] It should be noted that the specific model and specifications of the chassis body 10 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0024] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
