Description

Technical Field

[0001] This utility model relates to the field of tooling vehicle technology, and in particular to a top cover protection device for tooling vehicles. Background Technology

[0002] The roof protection device for work vehicles is a structural protection component installed on the top of the vehicle. Its main function is to reduce accidental impacts, falling objects or mechanical collisions from above during vehicle driving or operation, thereby ensuring the safety of equipment, goods and personnel inside the vehicle, and improving the overall rigidity and durability of the vehicle. It is suitable for complex working environments such as logistics transportation, engineering operations and special vehicles.

[0003] Existing tooling vehicle top covers still have some problems during use. For example, most existing protective layers are fixed to the top of the cover by adhesive, which means that the entire device must be disassembled and cleaned when replacing it. This is not only cumbersome, but also increases maintenance costs and time. In addition, most protective layers use a single material such as a rubber sheet for protection, and the single protective material cannot effectively absorb the impact from the outside world, making it difficult to provide a stable protective effect under impacts of different intensities.

[0004] To address these issues, we provide a protective cover for tooling vehicles. Summary of the Invention

[0005] The technical problem to be solved by this utility model is that in the prior art, most devices are inconvenient to replace the protective layer later, and when protecting the top cover, most use a single protective layer, which makes it difficult to absorb impacts of different intensities. Therefore, we propose a top cover protection device for tooling vehicles.

[0006] To achieve the above objectives, this application adopts the following technical solution: a top cover protection device for a tooling vehicle, comprising a tooling vehicle body, a top cover body fixedly connected to the top of the tooling vehicle body, a first protective layer provided on the top of the top cover body, a second protective layer fixedly connected to the top of the first protective layer, a shell fixedly connected to the bottom of the first protective layer, a spring fixedly connected to one side of the inner wall of the shell, a sliding plate fixedly connected to one end of the spring, a limit block fixedly connected to one side of the sliding plate, an inclined block fixedly connected to the other side of the sliding plate, a threaded pin threadedly connected inside the shell, and a pushing block fixedly connected to the bottom of the threaded pin.

[0007] Preferably, the top cover body has mounting grooves on both sides of the top, and the outer shell is slidably connected to the inside of the mounting grooves.

[0008] Preferably, a limiting groove is formed on one side of the inner wall of the mounting groove, and the limiting block is slidably connected inside the limiting groove.

[0009] Preferably, a sliding groove is provided on one side of the outer shell, and the limiting block is slidably connected inside the sliding groove.

[0010] Preferably, push rods are fixedly connected to both sides of the tooling vehicle body, and push handles are fixedly connected to the surface of the push rods.

[0011] Preferably, the first protective layer is made of polyethylene foam, and the second protective layer is made of rigid rubber.

[0012] The technical effects and advantages of this utility model are as follows: 1. This utility model, through the setting of the spring, can move the limiting block into the limiting groove through its own elasticity, thereby fixing the first protective layer and the second protective layer. The threaded pin and the pushing block can limit the slide plate through the inclined block, thereby ensuring that it will not loosen due to external factors during fixing. 2. This utility model provides double protection for the top cover body by using polyethylene foam and rigid rubber. The polyethylene foam can absorb the impact force of small intensity due to its porous characteristics, playing a preliminary buffering role, while the rigid rubber can resist the impact of large intensity due to its high hardness and toughness, effectively dispersing the impact force and preventing the top cover from being directly damaged. This enables it to adapt to impacts of different intensities and extends the service life of the tool vehicle top cover. Attached Figure Description

[0015] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0016] Example 1 Please see Figures 1-5 This utility model is a top cover protection device for a tooling vehicle, including a tooling vehicle body 1, a top cover body 2 fixedly connected to the top of the tooling vehicle body 1, a first protective layer 3 provided on the top of the top cover body 2, a second protective layer 4 fixedly connected to the top of the first protective layer 3, a shell 5 fixedly connected to the bottom of the first protective layer 3, a spring 6 fixedly connected to one side of the inner wall of the shell 5, a slide plate 7 fixedly connected to one end of the spring 6, a limit block 8 fixedly connected to one side of the slide plate 7, an inclined block 9 fixedly connected to the other side of the slide plate 7, a threaded pin 10 threadedly connected inside the shell 5, and a push block 11 fixedly connected to the bottom of the threaded pin 10.

[0017] Specifically: the first protective layer 3 and the second protective layer 4 can provide double protection for the top cover body 2, thereby effectively resisting external impacts and wear. There are two springs 6, which can move the limiting block 8 into the limiting groove 13 through their own elasticity, thereby fixing and limiting the first protective layer 3 and the second protective layer 4. The pushing block 11 can limit the slide plate 7 through the inclined block 9, thereby ensuring that after fixing, the limiting block 8 will not move to the outside of the limiting groove 13 due to external factors.

[0018] Example 2 Please see Figures 1-5 Based on embodiment 1, the top cover body 2 has mounting grooves 12 on both sides of the top, the outer shell 5 is slidably connected to the inside of the mounting groove 12, a limiting groove 13 is opened on one side of the inner wall of the mounting groove 12, the limiting block 8 is slidably connected to the inside of the limiting groove 13, a sliding groove 14 is opened on one side of the outer shell 5, the limiting block 8 is slidably connected to the inside of the sliding groove 14, a push rod 15 is fixedly connected to both sides of the tooling carriage body 1, and a push handle 16 is fixedly connected to the surface of the push rod 15. The material of the first protective layer 3 is polyethylene foam, and the material of the second protective layer 4 is hard rubber.

[0019] Specifically: There are two mounting slots 12, which facilitate the initial top mounting of the first protective layer 3 and the second protective layer 4. The limiting slot 13 assists the limiting block 8 in fixing and limiting the first protective layer 3 and the second protective layer 4. The sliding slot 14 provides sufficient moving space for the limiting block 8. The push rod 15 and the push handle 16 facilitate the user to push the tooling cart. Polyethylene foam has good buffering performance and shock absorption effect. When subjected to external impact, it can absorb most of the impact energy through its own compression deformation. Hard rubber has high hardness and wear resistance. Its surface is smooth and its structure is dense. It can not only further block external friction and scratches, but also resist the puncture of sharp objects to a certain extent, thereby significantly improving the protection capability of the top cover body 2.

[0020] Working principle: When the protective layer needs to be replaced, the user first rotates the threaded pin 10, which drives the push block 11 to move upward, separating it from the inclined block 9, thereby releasing the restriction on the slide plate 7. Then, the spring 6 will use its own elasticity to drive the limit block 8 to move through the slider, moving it to the preset position. Subsequently, the user pulls the first protective layer 3 and the second protective layer 4 to move. During the movement, the first protective layer 3 will drive the outer shell 5 to move, and the outer shell 5 will drive the limit block 8 to move. When the limit block 8 contacts the inner wall of the limit groove 13, the limit groove 13 will squeeze the limit block 8 to move. The limit block 8 will then squeeze the spring 6 through the slide plate 7, causing the limit block 8 to move into the outer shell 5. Then, the user can continue to pull to remove the first protective layer 3 and the second protective layer 4.

[0021] When installing a new first protective layer 3 and a second protective layer 4, the user first aligns the first protective layer 3 and the second protective layer 4 together through the bottom outer shell 5 and pushes them into the mounting grooves 12 on both sides of the top cover body 2. When the limiting block 8 contacts the inner wall of the mounting groove 12, the mounting groove 12 will squeeze the limiting block 8 to move. The limiting block 8 will then squeeze the spring 6 through the sliding plate 7, causing the limiting block 8 to move into the outer shell 5. When the limiting block 8 is flush with the limiting groove 13, the spring 6 will use its own elasticity to move the limiting block 8 into the limiting groove. Inside the 13, the first protective layer 3 and the second protective layer 4 are limited. Then, the user rotates the threaded pin 10, which drives the push block 11 to descend. When the push block 11 contacts the inclined block 9, the push block 11 pushes the inclined block 9 to move. The inclined block 9 pushes the slide plate 7 to move. The slide plate 7 pushes the limiting block 8 to move, so that the whole thing moves into the limiting groove 13, thereby locking the first protective layer 3 and the second protective layer 4, so as to facilitate the replacement of the first protective layer 3 and the second protective layer 4.

[0022] When encountering external impact, the first protective layer 3 made of polyethylene foam is responsible for absorbing high-frequency, low-intensity impacts, while the second protective layer 4 made of hard rubber resists high-intensity impacts and friction. Through the cooperation of the two, the top cover body 2 can be well protected, preventing structural damage such as dents and cracks caused by external force collisions during use. At the same time, it can also prevent the protective layer itself from being rapidly worn or failing due to the limitations of a single material during long-term use.

[0023] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
