DETAILED DESCRIPTION

[0020] The present application is further described in detail below in conjunction with the accompanying drawings.

[0021] In order to more clearly understand the technical solutions shown in the embodiments of the present application, the working principle of the existing end protection device for transferring large workpieces is first introduced.

[0022] During the transportation of this type of existing fine-machined parts, a thicker anti-collision layer needs to be tied to the end of the workpiece. This type of anti-collision layer is mostly made of sponge, foam and other materials, and some are made of rubber and other materials. On the one hand, this kind of protection structure has the problem of cumbersome operation during use, and needs to be manually bundled piece by piece, which has high labor intensity for workers. On the other hand, it has the disadvantage of high cost. Some consumables can only be used once or cannot be used on other workpieces. This requires the setting of a special structure to solve the problem of end protection.

[0023] See also Figure 1 and Figure 2 , disclosed in the embodiment of the present application, includes: a connecting seat 1, a sliding rod 2, a screw 3, a movable bar 4, a positioning nut group 5, an adjusting plate 6, a bottom connecting rod 7, a vertical connecting rod 8, a top connecting rod 9 and a gasket 10. A threaded hole and a sliding hole are provided on the connecting seat 1. The connecting seat 1 is symmetrically provided with two groups. The sliding rod 2 passes through the sliding holes on the two connecting seats 1 on the same side. The screw 3 passes through the threaded holes on each connecting seat 1 respectively. The end of the movable bar 4 is slidably connected to the sliding rod 2. The position of the movable bar 4 near the sliding rod 2 is respectively threadedly connected to the screw 3. The positioning nut The mother group 5 is respectively threadedly connected to the corresponding screws 3 on both sides of the movable bar 4, the adjusting plate 6 is fixedly connected to the inward end of the screw 3, the two ends of the bottom connecting rod 7 are respectively connected with the movable bar 4, the lower ends of the vertical connecting rod 8 are respectively connected with the movable bar 4, the top connecting rod 9 is respectively connected with the upper ends of the vertical connecting rods 8 at both ends, and the gasket 10 is connected to the surface of the inward side of the vertical connecting rod 8. A workpiece body 19 is arranged on the inner side of the gasket 10, and the gasket 10 is L-shaped. The gasket 10 contacts the surface of the edge position of the workpiece body 19 respectively.

[0024] Specifically, two connecting seats 1 are provided on each side, which can realize the support of the sliding rod 2 and the screw 3 respectively. The sliding rod 2 is relatively long, generally the length of the vehicle used or the length of the existing structure used by the pallet, tray, etc., which is easy to install and does not require subsequent cutting. When in use, after manually rotating the adjusting disk 6, the screw 3 can be rotated, so that the movable bar 4 slides to both sides. The ends of the movable bar 4 are respectively connected to the sliding rod 2, so as to realize the movement trajectory of the vertical screw 3. After adjusting to a length slightly larger than the workpiece body 19, the bottom connecting rod 7 is connected. On the bottom connecting rod 7, the vertical connecting rod 8 and the top connecting rod 9 in use, a large number of through holes are equidistantly opened, which are convenient for connection with each other. After being connected to each other, a frame structure with two sides slightly larger than the width of the workpiece body 19 is formed. When the structure is hit or collided, the external movable bars 4 transmits the impact to the lead screw 3, and then to the connecting seat 1, and when transmitting the impact force, it can be transmitted to the opposite side or the adjacent connecting seat 1. The set pad 10 can also support and isolate the edge corners of the workpiece body 19. The material is made of rubber, compressed foam and other materials that have a buffering effect. At the same time, the pad 10 can also play a secondary protective effect to enhance the overall protective effect. The set positioning nut group 5 is respectively connected to the lead screws 3 on both sides of the movable bar 4. More than two positioning nut groups 5 are respectively connected to the lead screws 3 on both sides of the movable bar 4, and the positions are fixed by the extrusion force to ensure that the adjusted movable bar 4 does not move and the lead screw 3 does not rotate; the structure is easy to install and has a wide range of applications. It can cope with different workpieces through adjustment. Compared with the existing welding support frame and bundled sponge protection forms, the efficiency is greatly improved, the protection performance is more stable, the practicality is good, and it has a good application prospect.

[0032] Specifically, the setting of the sliding sleeve 15 can limit the sliding trajectory of the movable bar 4, so that the movable bar 4 does not shake or get stuck during its movement, maintains the stability of the trajectory, and reduces its own wear, which helps to extend its service life.

[0033] See also Figure 2 As another specific embodiment provided in the application, it also includes a limiting nut 16, which is arranged on the surface of the outer side of the connecting seat 1 corresponding to the sliding rod 2, and the end of the limiting nut 16 is connected with the sliding rod 2 in a cooperative manner.

[0034] Specifically, the setting of the limit nut 16 can connect the slide rod 2 to facilitate its adjustment, and at the same time fix the slide rod 2 on the two connecting seats 1 to facilitate the transmission of force when subjected to force, making installation and adjustment more convenient.
