[0001] The utility model relates to the technical field of dust covers, in particular to a telescopic dust cover for a fork arm of an AGV forklift. Background Art

[0002] An AGV forklift is an important part of an automated logistics system and is used for material handling in an automated warehouse, a factory workshop or a logistics center. The AGV forklift includes a fork arm mechanism which can be telescopic, allowing the AGV forklift to extend the fork arm to contact distant goods or shelves without changing the position of the vehicle body and then retract to carry the goods; at the same time, it also has a vertical lifting function to place or pick up goods at different heights; in the fork arm mechanism, the lead screw structure is an important part to realize the conversion of linear motion, and the lead screw structure mainly consists of a lead screw, a lead screw nut, a guiding mechanism and a driving motor. There is a helix between the lead screw and the lead screw nut. When the lead screw rotates, due to the action of the thread, the lead screw nut will move linearly along the lead screw.

[0003] However, most of the existing lead screws are directly exposed, so in the later use, substances such as impurities and dust in the application environment are very likely to fall on the outside of the lead screw, which affects the later drive of the lead screw and further affects the later use of the whole device.

[0004] Therefore, it is necessary to provide a new telescopic dust cover for the fork arm of an AGV forklift to solve the above technical problems. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a telescopic dust cover for the fork arm of an AGV forklift.

[0008] Preferably, the protection component further includes fixing frames. There are two fixing frames which are respectively fixedly connected between the fork arm bottom cover and the fork arm top cover, and the vertical section end structure of the fixing frame is a horizontal U shape.

[0009] Preferably, the protection component further includes connecting frames. There are two connecting frames which are respectively fixedly connected to both ends of the bellows dust cover.

[0010] Preferably, two sets of symmetrically distributed insertion blocks are provided on the connection frame. The insertion blocks are slidably inserted into the fixed frame, and through holes are formed inside the insertion blocks.

[0011] Preferably, connection holes are formed at positions inside the fixed frame corresponding to the insertion blocks, and positioning blocks are provided at positions on the outer wall of the fixed frame corresponding to the connection holes.

[0012] Preferably, a connecting pin connected by threads is inserted between the positioning block, the connection hole and the through hole.

[0013] Preferably, the material of the bellows protective cover is nylon cloth material, polyester fiber material or plastic.

[0014] Compared with the related art, the telescopic dust-proof cover for the fork arm of the AGV forklift provided by the present utility model has the following beneficial effects:

[0015] By arranging a protective component between the fork arm bottom cover and the fork arm top cover of the fork arm mechanism in the present utility model, during the later use process, the bellows protective cover in the protective component can sleeve and protect the outside of the lead screw in the fork arm body when the fork arm mechanism is unfolded for use, thereby avoiding the phenomenon that external dust and other impurities fall on the outside of the lead screw during use, causing the lead screw to be blocked and affecting the later use of the device, and further making the later use of the fork arm mechanism smoother.

[0023] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] The following describes in detail the specific implementation of the present utility model in conjunction with specific embodiments.

[0025] Please refer to Figures 1 to 5 , a telescopic dust cover for the fork arm of an AGV forklift provided by an embodiment of the present utility model, the telescopic dust cover for the fork arm of the AGV forklift includes: a fork arm mechanism 1 and a protection component 2.

[0026] In an embodiment of the present utility model, please refer to Figure 1 , Figure 2 and Figure 3 , the fork arm mechanism 1 includes a fork arm bottom cover 11, a fork arm body 13 and a fork arm top cover 12, and the fork arm bottom cover 11 and the fork arm top cover 12 are connected by the fork arm body 13; the protection component 2 is arranged between the fork arm bottom cover 11 and the fork arm top cover 12, the protection component 2 includes a bellows protective cover 21, and the bellows protective cover 21 is detachably connected to the outside of the fork arm body 13.

[0027] It should be noted that: by arranging the protection component 2 between the fork arm bottom cover 11 and the fork arm top cover 12 of the fork arm mechanism 1, during the later use process, the bellows protective cover 21 in the protection component 2 can be sleeved on the outside of the lead screw in the fork arm body 13 when the fork arm mechanism 1 is unfolded for use, so as to avoid the phenomenon that external dust and other impurities fall on the outside of the lead screw during use, resulting in the blockage of the lead screw and affecting the later use of the device, and further making the later use of the fork arm mechanism 1 smoother. And by arranging the connecting frame 23 and the fixed frame 22 at both ends of the bellows protective cover 21 and inserting and connecting the connecting frame 23 and the fixed frame 22, when it is necessary to repair the fork arm body 13 in the fork arm mechanism 1 later, it can make it more convenient and fast for the staff to disassemble the bellows protective cover 21, so it is convenient for the staff to repair the fork arm body 13 later.

[0028] In an embodiment of the present utility model, please refer to Figures 1 to 5, the protective component 2 further includes a fixed frame 22. There are two fixed frames 22, which are respectively fixedly connected between the fork arm bottom cover 11 and the fork arm top cover 12. The vertical section end structure of the fixed frame 22 is a horizontal U-shape. The protective component 2 further includes a connecting frame 23. There are two connecting frames 23, which are respectively fixedly connected to both ends of the bellows protective cover 21. Two groups of symmetrically distributed insertion blocks 231 are provided on the connecting frame 23. The insertion blocks 231 are slidably inserted into the fixed frame 22. A through hole 233 is opened inside the insertion block 231. A connection hole 222 is opened at the relative position of the inside of the fixed frame 22 and the insertion block 231. A positioning block 221 is provided at the relative position of the outer wall of the fixed frame 22 and the connection hole 222. A connecting pin 24 connected by thread is inserted between the positioning block 221, the connection hole 222 and the through hole 233.

[0029] It should be noted that: by setting the vertical section end of the fixed frame 22 as a horizontally placed U-shaped structure, the insertion block 231 can be smoothly inserted into the fixed frame 22, which is convenient for connecting the fixed frame 22 and the connecting frame 23. By inserting the connecting pin 24 between the positioning block 221, the connection hole 222 and the through hole 233, the connecting pin 24 can smoothly limit the insertion block 231, avoiding the phenomenon that the insertion block 231 slides randomly inside the fixed frame 22, thereby improving the connection stability between the connecting frame 23 and the fixed frame 22;

[0030] Moreover, the specifications of the fixed frame 22 and the connecting frame 23 are smaller than those of the fork arm top cover 12 and the fork arm bottom cover 11. Therefore, when the fork arm mechanism 1 is folded and contracted later, the fork arm mechanism 1 can proceed smoothly.

[0031] In this embodiment, the material of the bellows protective cover 21 is polyester fiber material, which has the characteristics of waterproof, mildew-proof, anti-tensile, etc. It is a material suitable for making protective covers and is adapted to the working scenario of the AGV cart.

[0032] The working principle of the telescopic dust-proof cover for the fork arm of the AGV forklift provided by the present utility model is as follows:

[0033] In the later stage of using this device, when the fork arm body 13 in the fork arm mechanism 1 works, the fork arm top cover 12 can be smoothly unfolded upward. During the unfolding process of the fork arm top cover 12, it can smoothly drive the top of the bellows protective cover 21 in the protective component 2 to move, thereby enabling the bellows protective cover 21 to be unfolded and smoothly covering the outside of the fork arm body 13. Therefore, during the use of the fork arm mechanism 1, the lead screw in the fork arm body 13 is not exposed outside, and external dust and other impurities do not fall on the outside of the lead screw, causing the lead screw to be blocked and affecting the later work of the fork arm body 13. Therefore, the later use experience of this device can be improved;

[0034] When it is necessary to overhaul the fork arm body 13 in the fork arm mechanism 1 in the later stage, the staff can first make a certain opening in the fork arm top cover 12, and then turn the connecting pin 24 to smoothly move the connecting pin 24 out of the positioning block 221, the connecting hole 222 and the through hole 233, so as to release the limit on the insertion block 231. At this time, the connecting frame 23 can be directly slid outwards to separate the connecting frame 23 from the fixed frame 22, and then the fork arm top cover 12 and the fork arm body 13 can be disassembled to quickly expose the fork arm body 13, which is convenient for the staff to repair.

[0035] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
