Description

Technical Field

[0001] The utility model relates to the field of screen fixing devices, in particular to a fast-disassembly and assembly screen clamping and fixing device. Background Art

[0002] The design of the swing screen is a high-efficiency screening machine specially designed to meet the needs of large-scale and high-precision screening. The swing screen is a mechanical simulation of this. It is currently the most effective simulation of the effective principle of artificial screening movement, which conforms to all fine and ultra-fine powders and particulate materials, and is particularly suitable for difficult-to-handle materials. The square swing screen can also be called a reciprocating vibrating screen or a precision vibrating screen. The vibration force generated by its motor drive device is an inertial force that rotates around a fixed axis and changes direction in a certain regularity. In essence, it is the reciprocating inertial force formed by the rotation of the eccentric wheel around the fixed axis. However, the existing screen is not convenient to disassemble, resulting in the inability to clean and repair the screen. After long-term use of the screen, the screening efficiency will slow down after the mesh is blocked, which cannot meet people's use needs, and it is impossible to ensure that the clamping force is sufficient, making the screen unstable, which can easily affect the convenience of use of the entire screen fixing device. Utility Model Content

[0005] Preferably, by setting a clamping assembly and the self-tension of the telescopic spring, the clamping connection between the limit rod and the first limit hole is made more stable, thereby avoiding the phenomenon of falling off and affecting the later use effect. The bottom of the limit rod is designed as a slope, which helps to guide the limit rod into the hole and reduce the difficulty of alignment. When the screen frame needs to be disassembled, the horizontal plate is pulled up to separate the limit rod from the first limit hole, so that the screen frame can be quickly disassembled, thereby greatly improving the convenience of use of the entire screen fixing device.

[0006] Preferably, the mounting assembly includes a fixing block, a mounting hole and a fastening bolt.

[0008] Preferably, a screen is provided inside the screen frame. The screen is made of a metal mesh material with good wear resistance and strength, and is suitable for occasions with high requirements for corrosion resistance.

[0009] Preferably, the clamping assembly includes a fixed rod, a fixed plate, a limit rod, a telescopic spring and a cross plate. The fixed rods are arranged in two groups, and the same group of fixed plates are installed on the top of the two groups of fixed rods.

[0010] Preferably, the bottom of the limit rod is designed with a bevel, so that the limit rod can be more easily found in the correct position and inserted into the first limit hole and the second limit hole. The bevel helps to guide the limit rod into the hole, reducing the difficulty of alignment.

[0011] Preferably, a transverse plate is provided at the upper ends of the three groups of limit rods. When the screen frame needs to be disassembled, the transverse plate is pulled upward to separate the limit rods from the first limit holes, so that the screen frame can be quickly disassembled.
