[0002] Patent application CN221007180U includes a nickel release abrasion tester body and a roller barrel located on the nickel release abrasion tester body. A placement box is fixedly connected to the inner wall of the roller barrel. Two clamping plates are slidably connected to the side of the placement box away from the roller barrel. A clamping assembly for controlling the clamping plates to hold an object is provided inside the roller barrel. Fixing components for securing the object are provided on the two clamping plates. The advantages are: This invention has the following beneficial effects: When an object needs to be tested, the clamping assembly drives the two clamping plates to fix the object inside the roller barrel. If a small object needs to be tested, the fixing components can fix it between the two clamping plates, thereby avoiding the problem of additional damage caused by the object colliding with the roller barrel during the use of the nickel release abrasion tester, and improving the testing effect.

[0003] In the prior art, including the aforementioned patent, the device lacks a protective device on the outside of the roller. As a result, during operation, the cover plate may accidentally open due to lack of locking, causing parts or objects to be detected inside the roller to fly out. Furthermore, during operation, it cannot prevent external debris from affecting the operation of the equipment, thus failing to provide a guarantee for the safety of the working environment. Utility Model Content

[0004] The purpose of this invention is to provide a protective device for a nickel release wear tester, in order to solve the problem that the device mentioned in the background art does not have a corresponding protective device and may pose a threat to the safety of nearby workers during operation.

Two sets of locking blocks and top blocks are symmetrically disposed along the center line of the protective cover, and the locking blocks and top blocks are located outside the rotating shafts at both ends of the rotating drum of the device.

[0006] Furthermore, a guide rail is slidably provided on one side of the top block. The guide rail is used to limit the movement trajectory and range of the top block, so that it can only slide up and down. One side of the guide rail is also fixedly connected to the main body. Guide rails are slidably provided on both sides of the lower end of the card block. The lower end of the guide rail is fixedly connected to the main body. The guide rail is also used to limit the movement trajectory and range of the card block.

[0007] Furthermore, a spring is fixedly installed at the lower end of the locking block between the guide rails. Two springs are symmetrically arranged along the center line of the locking block. A friction block is fixedly installed on the upper surface of the locking block. The friction block contacts the rotating shaft inside the device and is used to limit the rotation speed of the rotating shaft.

[0008] Furthermore, a sleeve is fixedly installed on one side of the protective cover inside the main body, and a mounting bracket is fixedly installed on the inner side of the sleeve. A telescopic rod is fixedly installed in the middle of the mounting bracket, and a sealing gasket is fixedly installed at the other end of the telescopic rod. A spring is installed on the outer side of the telescopic rod between the mounting bracket and the sealing gasket, and the sealing gasket can contact the outer edge of the mounting bracket to achieve a sealing effect.

[0009] Furthermore, a piston rod is slidably disposed inside the sleeve on the side away from the mounting bracket, and a top post is fixedly disposed at the other end of the piston rod. The top post passes through the main body and contacts the protective cover. A corresponding slot is opened on the side of the protective cover near the top post, so that the top post can be inserted into the slot. Springs are disposed around the sleeve, and the two ends of the springs are fixedly connected to the top post and the main body, respectively.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the protective device for the nickel release wear tester is reasonable and has the following advantages:

[0011] (1) The protective cover can prevent external factors from affecting the device detection. Furthermore, the setting of the top block and the locking block can prevent the roller inside the device from rotating too fast when the protective cover is opened. This can protect the safety of workers when loading or unloading materials or maintaining equipment, and will not hinder the normal operation of the device. In addition, the top block and the locking block and their related components are relatively common parts, which can also reduce the manufacturing cost of the device.

[0012] (2) The locking component on one side of the protective cover can prevent the protective cover from opening when it is subjected to a strong impact force without hindering the normal opening of the protective cover. This can prevent the device from throwing out the test object or other parts during operation, thus further enhancing the safety of workers. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-7 The present invention provides a technical solution as follows:

[0023] In this embodiment, a protective device for a nickel release wear tester includes a main body 1. A protective cover 2 is rotatably disposed on one side of the main body 1. A connecting rod 3 is rotatably disposed on the lower outer surface of the protective cover 2. A top block 4 is rotatably disposed at the lower end of the connecting rod 3. A locking block 6 is disposed at the lower end of the top block 4. Two sets of locking blocks 6 and top blocks 4 are symmetrically disposed along the center line of the protective cover 2. The locking blocks 6 and top blocks 4 are located outside the rotating shafts at both ends of the device's rotating drum.

[0024] In this embodiment, a guide rail 5 is slidably provided on one side of the top block 4. The guide rail 5 is used to limit the movement trajectory and range of the top block 4, so that it can only slide up and down. One side of the guide rail 5 is also fixedly connected to the main body 1. Guide rails 7 are slidably provided on both sides of the lower end of the card block 6. The lower end of the guide rail 7 is fixedly connected to the main body 1. The guide rail 7 is also used to limit the movement trajectory and range of the card block 6.

[0025] In this embodiment, a guide rail 5 is slidably provided on one side of the top block 4. The guide rail 5 is used to limit the movement trajectory and range of the top block 4, so that it can only slide up and down. One side of the guide rail 5 is also fixedly connected to the main body 1. Guide rails 7 are slidably provided on both sides of the lower end of the card block 6. The lower end of the guide rail 7 is fixedly connected to the main body 1. The guide rail 7 is also used to limit the movement trajectory and range of the card block 6.

[0026] In this embodiment, a sleeve 10 is fixedly installed on one side of the protective cover 2 inside the main body 1. A mounting bracket 11 is fixedly installed on one side of the sleeve 10. A telescopic rod 12 is fixedly installed in the middle of the mounting bracket 11. A sealing gasket 14 is fixedly installed at the other end of the telescopic rod 12. A spring 13 is installed on the outer side of the telescopic rod 12 between the mounting bracket 11 and the sealing gasket 14. The sealing gasket 14 can contact the outer edge of the mounting bracket 11 to achieve a sealing effect.

[0027] In this embodiment, a piston rod 15 is slidably disposed inside the sleeve 10 on the side away from the mounting bracket 11. A top post 16 is fixedly disposed at the other end of the piston rod 15. The top post 16 passes through the main body 1 and contacts the protective cover 2. A corresponding slot is opened on the side of the protective cover 2 near the top post 16 so that the top post 16 can be inserted into the slot. Springs 17 are disposed around the sleeve 10. The two ends of the springs 17 are fixedly connected to the top post 16 and the main body 1, respectively.

[0028] Working principle: During the use of the device, when the protective cover 2 is open, the top block 4 is positioned above the rotating shaft; at the same time, the locking block 6 and friction block 9 located below the rotating shaft are tightly pressed against the rotating shaft; this setting can effectively limit the rotation speed of the drum in the event of accidental start-up, thereby avoiding threats to the personal safety of workers; after the placement of the object to be tested is completed, during the closing of the protective cover 2, the top block 4 will press the locking block 6 downwards, at which point the rotating shaft can rotate freely, ensuring the normal operation of the device;

[0029] If the cover plate on the rotating drum inside the device fails to close completely, some smaller objects will be directly intercepted by the protective cover 2, while the impact force generated when some heavier objects hit the protective cover 2 will cause the protective cover 2 to move upward. Since the opening speed of the protective cover 2 under these circumstances will inevitably be greater than the normal opening speed of the worker, the top column 16 on one side of the protective cover 2 will move rapidly to one side, thereby driving the piston rod 15 to push the air in the sleeve 10 towards the sealing gasket 14. As a result, the air flow velocity on the sealing gasket 14 side increases, and the gap around the sealing gasket 14 cannot allow a large amount of air to pass through instantly. Under the action of air pressure, the sealing gasket 14 will be pushed against the mounting bracket 11. Based on this, the top column 16 cannot retract, and the protective cover 2 cannot be opened. When the impact force disappears, all components on one side of the protective cover 2 will return to their original positions under the action of the spring. When the worker opens the protective cover 2 at a normal speed, the gas flow velocity in the sleeve 10 is relatively slow and will not affect the sealing gasket 14 when it passes through it, thus allowing the protective cover 2 to be opened smoothly.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
