Anti-stripping pipe clamp

Abstract

The invention belongs to the field of automobile connecting pieces, specifically relates to an anti-stripping pipe clamp. The anti-stripping pipe clamp comprises a nip used for clamping pipe fittings. The other side of the nip relative to a clamping interface used for clamping pipe fittings is reversely provided with inserting columns orderly. Each inserting column is distributed with right tapered through holes penetrating the inserting column. The through holes form a hollow expansive sleeve structure of the inserting column, and the inserting columns and automobile fixing pieces form an inserting type expansive nail match. The pipe clamp also comprises expansive pins used for forming an inserting match with the inserting columns which are in a shape of an expansive sleeve. The inserting ends of the expansive pins are forwardly provided with sheltering sections orderly along the axes. The sheltering sections and the top ends of the inserting columns form a unidirectional sheltering match. The separation distances of the sheltering sections on the expansive pins and the inserting ends are greater than or equal to the lengths of the through holes. The unidirectional stop performance is realized after the expansive pins are inserted in the inserting columns by arranging the sheltering sections at the inserting ends of the expansive pins, so that the storage and transportation cost of the pipe clamp is obviously reduced, and meanwhile the self-working performance of the pipe clamp is maintained.

Description

technical field [0001] The invention belongs to the field of automobile connectors, and in particular relates to an anti-loosening pipe clamp. Background technique [0002] The pipe clamp is a fixing device for fixing the oil pipe or other pipe fittings to the vehicle body or a relatively fixed position. When in use, one end is fixed at the fixed position of the vehicle body, and the other end is clamped on the automobile oil pipe or other pipe fittings to implement the purpose of fixing oil pipes and other pipe fittings. At present, the commonly used pipe clamp structure usually includes a jaw with a "Ω" structure. The opening end of the jaw forms a clamping interface that snaps onto the outer wall of the pipe. The middle of the other end of the jaw is opposite to the position of the opening end. An insertion column for inserting the body fixing parts is arranged in succession, and the insertion column is a hollow expansion sleeve structure. Of course, the pipe clamp also ...

Problems solved by technology

When the above-mentioned structure is in use, its own disadvantages gradually appear: due to the integrated structure between the jaw and the insertion column, the small expansion pin is isolated. On the one hand, it often leads to the need to Shipping and storage in separate boxes takes up a lot of transportation and storage space, resulting in a significant increase in its transportation and site costs; Low assembly efficiency

Some manufacturers also discovered the above problems during production, and began to put the expansion pins into the insertion columns to form an assembly to realize the overall boxing; however, because the expansion pins themselves have a cylindrical structure with the same diameter , if the insertion depth of the expansion pin is too shallow, during actual handling, the expansion pin will often slide off from the insertion column due to the bumping of the vehicle body or other factors; It is always in an inflated state, making it lose its elastic expansion characteristics in the subsequent assembly process, which ultimately affects its assembly efficiency and stability, thus causing great trouble to the staff
