Description

Tarpaulin hanging buckle

Technical Field

The invention relates to an accessory for tarpaulin, in particular to a tarpaulin hanging buckle.

Background

With the rise of the logistics industry, the transportation industry develops faster and faster. As an effective covering facility, the application of the tarpaulin also increases the demand, and the fixation of the tarpaulin is also an important link in transportation. The common fixing method of the tarpaulin is to use a dotter to punch a row of tarpaulin rings with the same distance to thread ropes at the edge of the tarpaulin. The material of the tent ring is roughly divided into iron, stainless steel, aluminum and plastic. However, the tent ring has the problem of insufficient strength: the iron tarpaulin ring is easy to rust, the aluminum tarpaulin ring is easy to deform, the plastic tarpaulin ring is easy to crack, the stainless steel tarpaulin ring is relatively firm, but the tarpaulin ring damages the structure of the tarpaulin, thereby forming the weak point on the tarpaulin, and the tarpaulin is easy to tear when the stress is large, and the application is limited. And the dotter also has the potential safety hazard when operating, and improper operation easily causes the pressure injury of finger.

Detailed Description

The following further describes embodiments of the present invention with reference to examples.

Example one

As shown in fig. 1-3, the tarpaulin hanging buckle comprises a first connecting portion connected with the tarpaulin and a second connecting portion connected with the carrier, wherein the second connecting portion is connected with the first connecting portion, the first connecting portion comprises an upper gland 1 and a lower support cover 2, the lower end surface of the upper gland is provided with an upper groove 13, the upper end surface of the lower support cover is provided with a lower groove 23, the upper gland can be detachably and fixedly installed on the lower support cover, and the upper groove and the lower groove are matched to form a space 4 for placing the tarpaulin to be wrapped.

Wherein, the second connecting part is a tent ring 3 which is used for being connected and fixed with a rope or a hook.

Taking a cylindrical wrapping edge as an example, the upper groove and the lower groove are semicircular grooves, and a cylindrical space is formed after the upper groove and the lower groove are matched to fix the cylindrical wrapping edge, the diameter of the cylindrical space is preferably equal to that of the cylindrical wrapping edge and can be slightly smaller/larger, and after the wrapping edge is fixed, no obvious gap exists between the lower end surface of the upper gland and the upper end surface of the lower support cover, and between the lower end surface of the upper gland and the upper end surface of the lower support cover and the cylindrical wrapping edge.

Wherein, go up the both ends of gland, can fix under in the support and cover through following mode, if: 1. both ends are fixed in a screw fixing mode; 2. one end is fixed by a screw, and the other end is hinged and buckled.

The material of first connecting portion and second connecting portion is thermoplastic material injection moulding such as PE, PP, PA, PPS, TPEE, and the second connecting portion with hold in the palm the lid down through the integrated into one piece that moulds plastics for it has excellent comprehensive properties to hang the knot, hangs the knot like nylon: the weight is light, mechanical strength is high, the wear resistance is good, high temperature resistance, self-extinguishing property is achieved, the service life of the hanging buckle is greatly prolonged, the hanging buckle can be repeatedly used, and the hanging buckle can resist the pull force of 1400N at most without being damaged when being applied to the field of automobile tarpaulin.

One end of the upper gland is provided with a positioning connecting buckle, the other end of the upper gland is provided with an upper mounting hole 12, and in the embodiment, the mounting hole is a threaded hole.

One end of the lower supporting cover close to the first connecting part is provided with a button hole 21 used for being matched and installed with the positioning connecting button, the other end of the lower supporting cover is provided with a threaded hole 22, and a screw penetrates through the mounting hole to be connected with the threaded hole.
