Embodiment Construction

[0008] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0009] in figure 1 In, the plastic two-way stretch grid mesh fixture, including the clamp body 6, the high temperature compression spring 3, the spring sleeve 2, the upper clamp 5, the lower clamp 7, the cylindrical pin 1 and the cylindrical pin 4, the upper part of the clamp body 6 is equipped with a cylindrical pin 1. The middle part of the upper jaw is equipped with a cylindrical pin 4, a spring sleeve 2 is installed between the cylindrical pin 1 and the cylindrical pin 4, and a high temperature resistant compression spring 3 is installed in the spring sleeve 2.

[0010] The jaw faces of the upper pliers 5 and the lower pliers 7 are stamped into fish-scale inverted teeth.

[0011] The specific working principle. When clamping the plastic sheet, use the clamp to gently press the upper pliers 5, the upper pliers 5 of the clamp will automatically close with the l...

Abstract

The invention relates to the technical field of plastic processing machinery, in particular to a plastic biaxially stretched grid net clamp. Including clamp body, high temperature pressure spring, spring sleeve, cylindrical pin, upper clamp and lower clamp, each of the upper part of the clamp body and the middle part of the upper clamp is equipped with a cylindrical pin, and a spring sleeve is installed between the cylindrical pins, high temperature resistant pressure type The spring is installed in the spring casing, and the jaw surfaces of the upper and lower jaws are stamped into fish scale inverted teeth. Compared with the prior art, the present invention can keep the fixture with a long-lasting and large clamping force. During the stretching process, the fixture does not change shape, the spring does not fall off, the plastic sheet does not come off the clamp, and does not swim. According to products of different thicknesses, It is very convenient to replace the spring.

Description

Technical field: [0001] The invention relates to the technical field of plastic processing machinery, in particular to a plastic bidirectional stretch grid mesh clamp. Background technique: [0002] Plastic biaxially stretched grid mesh is widely used in soft soil foundation treatment and reinforced soil structure in water conservancy, construction, transportation and other projects. It is made of plastic plates with holes punched in clamps and stretched by an oven. The traditional clamp is made of steel plate welding or casting split connection. The clamping force between the upper clamp and the lower clamp of the clamp is maintained by the leaf spring. During the stretching process, it is heated by the oven for a long time, and the elasticity of the leaf spring will be reduced. If it is weakened, the clamping force will be reduced, which often causes the spring sheet to fall from the clamp body, causing the failure of the plastic sheet to detach. The upper jaw surface and the ...
