Description

Straining device of screen cloth chair

Technical Field

The utility model belongs to the technical field of furniture, a straining device of screen cloth chair is related to.

Background

The mesh chair mainly comprises a bracket and mesh, wherein the bracket is generally made of stainless steel. The stringing pipe is connected to screen cloth both sides, if the screen cloth can not the tensioning, then can relax and look unattractive after long-term the use, also influences the comfort level simultaneously. The mesh cloth chair with the tensioning function is troublesome to assemble, and the mesh cloth and the cloth penetrating pipe are assembled by a factory and then leave the factory due to the fact that a user does not have a special assembling tool, so that the furniture packing carton is large in size.

SUMMERY OF THE UTILITY MODEL

The utility model aims at having the above-mentioned problem to current technique, provided a straining device of screen cloth chair, do not need specialized tool or equipment, the user just can easily assemble the screen cloth chair and with the screen cloth tensioning, does not increase the packing size again, saves a large amount of freight.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a straining device of screen cloth chair, its characterized in that, including connecting in screen cloth both sides and parallel arrangement's poling and being curved violently pipe, is equipped with the confession on the poling and violently manages the connecting piece that inserts and adjustable insertion depth, the connecting piece includes guide pin bushing, adjusting bolt and rivet nut, and it has the mounting hole to open on the poling, and rivet nut fixes in the mounting hole and with adjusting bolt threaded connection, and guide pin bushing one end has connecting plate and connecting plate can dismantle fixed connection on the poling, violently the tip inlay card of pipe portion has the end cap, violently the pipe portion insert in the guide pin bushing and the end cap offsets with the adjusting bolt tip and lean on.

During installation, the end of the transverse pipe is inserted into the guide sleeve, the guide sleeve is detachably connected with the cloth penetrating pipe, and no special installation tool or equipment is needed. When the tension degree of the mesh cloth needs to be adjusted, the adjusting bolt is rotated, when the front end of the adjusting bolt extrudes the plug, the arc-shaped transverse pipe is compressed, the bending degree is increased, the distance between the two cloth penetrating pipes is shortened, and the mesh cloth becomes loose; when the adjusting bolt moves backwards, the transverse pipe is unfolded to extend, the cloth penetrating pipes are pushed to move oppositely, and the mesh cloth is tensioned.

Furthermore, the inner diameter of the guide sleeve is 28mm, and the outer diameter of the transverse pipe is 26 mm.

Furthermore, the plug is made of rubber materials and is provided with a blocking edge.

Furthermore, the mounting hole on the cloth penetrating pipe and the guide sleeve are concentrically arranged.

Furthermore, the connecting plate is connected to the cloth penetrating pipe through a bolt and nut assembly.

As another scheme, the connecting plate is connected to the cloth penetrating pipe through a clamping and embedding structure, two L-shaped clamping plates are fixedly welded on the side face of the cloth penetrating pipe, and two ends of the connecting plate are clamped in the L-shaped clamping plates.

Compared with the prior art, the tensioning mechanism of the mesh chair has the following advantages:

1. the packaging and boxing occupy less space and reduce the transportation cost.

2. The adjustment is convenient, and the tensioning of the screen cloth can be realized only by rotating the adjusting bolt.

3. The installation is convenient, and the user can install the mesh chair by oneself.
