Description

Technical Field

[0001] The utility model relates to the technical field of roller presses, in particular to a double blind hole anchoring connection structure. Background Art

[0002] Anchors are devices used to fix or connect objects or structures to the ground or other stable supports. They can be mechanical, such as anchor rods, anchor bolts, expansion bolts, etc., or chemical, such as chemical anchoring glue. The purpose of anchors is to provide sufficient grip and stability to ensure that the fixed object or structure can withstand the predetermined load and moment.

[0003] When installing a roller press, anchors are required to fix the roller press to a wall or the ground. Currently, most existing fixing methods use expansion bolts as fixing parts to fix the roller press. When fixing, anchors such as expansion bolts are difficult to fix according to the length between the wall and the roller press, resulting in a narrow scope of application and poor practicality. Utility Model Content

[0004] The utility model aims to provide a double blind hole anchor connection structure, which can solve the problem that anchor pieces such as expansion bolts are difficult to fix according to the length between a wall and a roller press when fixing.

[0005] To achieve the above object, the utility model provides the following technical solutions: a double blind hole anchor connection structure, comprising a protective sleeve, a threaded sleeve and a mounting block, wherein a bidirectional screw rod is fixedly installed inside the protective sleeve;

[0006] There are two groups of threaded sleeves, which are respectively located on both sides of the bidirectional screw rod. The bidirectional screw rod is used to drive the two groups of threaded sleeves to move laterally.

[0007] A limiting block is arranged on the mounting block, a connecting plate is fixedly installed on one end of the threaded sleeve, and the limiting block is used to connect the connecting plate with the mounting block.

[0008] Preferably, a limiting support plate is fixedly installed on one side of the mounting block, a limiting spring is fixedly installed on one side of the limiting support plate, a limiting block is fixedly installed on one side of the limiting spring, a sliding rod is fixedly installed on one side of the limiting block, one end of the sliding rod extends to the other side of the limiting support plate and a handle is fixedly installed, and the sliding rod and the limiting support plate are slidably installed.

[0009] Preferably, a groove is provided inside for the limit block to move, and one side of the limit block extends into the groove on the connecting plate.

[0010] Preferably, an opening is provided inside the mounting block to allow the connecting plate to move.

[0011] Preferably, a groove is provided on the mounting block for the connection plate to move, the groove is located at the front side of the opening on the mounting block and the connection plate is located in the groove. This arrangement facilitates the positioning of the connection plate.

[0012] Preferably, one end of the bidirectional screw extends to the interior of the threaded sleeve and the bidirectional screw and the threaded sleeve are threadedly mounted, so that the distance between the two sets of connecting plates can be easily adjusted.

[0013] Preferably, a threaded groove matching the bidirectional screw rod is provided inside the threaded sleeve, so that the position of the threaded sleeve can be adjusted easily.

[0014] Compared with the prior art, the beneficial effect of the utility model is that the double blind hole anchor connection structure can adjust the distance between the two groups of connecting plates according to the distance between the two groups of mounting blocks through the setting of the two-way screw rod and the threaded sleeve. In this way, in the process of fixing the roller press, one group of connecting plates can be connected to the blind holes on the roller press first, and then the other group of connecting plates can be connected to the blind holes on the wall. Then, the distance between the two groups of connecting plates can be adjusted by rotating the two-way screw rod, and the wall and the roller press body can be tightened by the two-way screw rod and the threaded sleeve. In this way, the strength of the roller press after installation can be increased to avoid shaking and swaying of the roller press during operation. Then, the connecting plate and the mounting block can be connected through the setting of the limit block. Moreover, this connection method is relatively simple and convenient for workers to disassemble and reuse it, which improves the installation efficiency of workers and reduces the installation cost of the roller press.
