Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering operation tools, and in particular to a chain plate opening and closing tool. Background Technology

[0002] The applicant's prior invention patent application, number 2025106079481, discloses an oil bath type air intake filter, which mentions a link structure for connecting the curtain slats, as follows: Figure 4 As shown, since the chain is composed of multiple links connected end to end, only a brief description of the link structure is given here. Each link includes a pair of chain plates 1, with connecting pins 10 at both ends. A sleeve 11 is rotatably mounted on each connecting pin 10, positioned between the chain plates 1. A strip-shaped hole 12 is formed on the chain plate 1, with a notch 14 on the outer side of the hole 12. A concave hook 16 is inserted through each end of the strip-shaped hole 12, used to hang corresponding structural components. The notch 14 facilitates the insertion of the hook 16. After the hook 16 is inserted into the slot 12, to ensure that the hook 16 does not fall off when the chain moves, the slot 12 needs to be closed. This involves bending the notch 14 of the chain plate 1 inward. During closure, the operator uses conventional tools with a biting ability, such as pliers. However, using such tools for closure is inconvenient. While this is easier when the chain is not hooked, connecting the chain and sprocket with the existing structural components increases the difficulty due to the added weight. Connecting the chain and sprocket reduces the difficulty of connection, but the space and obstruction of the corresponding structural components make closure difficult. Utility Model Content

[0003] This utility model provides a chain plate opening closing tool to solve the shortcomings of the prior art and has strong practicality in addressing the problem of inconvenient closing of the chain plate opening.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A chain plate opening and closing tool includes a connecting part sleeved on a chain plate or a concave hook. The connecting part is provided with a pressing part. The pressing part acts on the chain plate to close the opening of the chain plate. The pressing part acts on the outside of the chain plate, thereby bending the notch of the chain plate inward, thereby achieving the effect of closing the strip hole.

[0005] Optionally, the connecting part includes an arc-shaped hook plate, which has a hook-shaped structure. One end of the arc-shaped hook plate is formed with a connecting plate. The hook part of the arc-shaped hook plate is fitted onto the horizontal section of the hook to facilitate the closing operation. The hook-shaped structure design ensures the stability of the connection between the hook and the connecting part when the tool is rotated.

[0006] The clamping part includes a clamping plate formed on the other end of the connecting plate. The width of the clamping plate is greater than the width of the connecting plate, so that the lower end of the clamping plate forms an action shoulder with the outer side of the connecting plate. In application, the action shoulder acts on the chain plate, and the arc-shaped hook plate is hung on the concave hook. When the connecting part rotates around the axial direction of the hook section, it can act on the outer wall of the chain plate through the action shoulder to perform a closing operation. In order to ensure the connection effect between the action shoulder and the chain plate during the closing operation, a corner groove is provided on the chain plate, and one edge of the action shoulder is engaged in the corner groove to facilitate bending operation.

[0007] Furthermore, the back side of the clamping plate is formed with reinforcing strips to improve the structural strength of the clamping plate and prevent the clamping plate from bending.

[0008] Optionally, the connecting part includes a lower block, with slots at both ends of the upper wall of the lower block, through which a chain plate passes. A rotating rod is rotatably mounted on the lower block, with a nut threadedly connected to the lower end of the rotating rod. The nut is located on the lower side of the lower block. An upper plate is welded to the upper end of the rotating rod, located on the upper side of the lower block. A rectangular post is welded to the upper plate, and a rectangular sleeve is fitted onto the rectangular post. A screw is welded to the upper end of the rectangular post, and a threaded sleeve is threadedly connected to the screw. A push plate is provided at the lower end of the threaded sleeve, and an actuating plate is provided at the upper end of the rectangular sleeve. The lower wall of the push plate abuts against the upper wall of the actuating plate. A connecting protrusion is formed on one side of the lower end of the rectangular sleeve, and a clamping rod is welded to the other end of the connecting protrusion. This solution closes the opening by connecting the lower block and the chain plate. During operation, the threaded sleeve pushes the rectangular sleeve downwards, which in turn acts on the chain plate through the clamping rod, thus achieving the closing operation. This operation method improves stability compared to the previous solution. In addition, the closing operation at both ends of the chain plate can be performed simultaneously by adjusting the position of the clamping rod.

[0009] Furthermore, multiple extension rods are welded to the outer periphery of the threaded sleeve to facilitate gripping when the threaded sleeve rotates.

[0010] Furthermore, a pin is provided at the outer end of the upper plate, and insertion platforms are formed on both sides of the lower block. The pin is inserted on the insertion platforms to lock the position of the clamping rod during operation, so as to avoid the problem of failure to close due to the clamping rod rotating to one side.

[0011] Furthermore, the upper end of the pin is welded with a head, and a hanging ring is provided on the head, which facilitates the insertion and removal of the pin.

[0012] The advantages of the above technical solution are: This invention facilitates the closing of the chain plate at the notch and the fixing of the hook position, and reduces the difficulty of hook connection. Attached Figure Description
