Abstract

The utility model provides a connection clamping hoop structure for a two-wall straight corrugated pipe. The connection clamping hoop structure comprises the two-wall straight corrugated pipe and a connection piece, wherein the port of the two-wall straight corrugated pipe is not provided with a bellmouth, and the two-wall straight corrugated pipe is connected through the connection piece; the connection piece is a clamping hoop piece consisting of two opposite half arches, and two ends of the clamping hoop piece are fastened by bolts, or the connection piece consists of two opposite half arches, and one end of each of the two opposite half arches is movably connected, and the other end of each of the two opposite half arches is fastened by a bolt; and an elastic material is attached inside the clamping hoop piece. The connection clamping hoop structure has the advantages that: the operation for processing the bellmouth part is saved, and the straight pipe part is produced continuously, so that mechanically stable running is guaranteed, and extra loss of a machine is reduced. The two-wall straight corrugated pipe is connected through the connection piece; and the connection piece is produced independently, so that standard work with relatively high requirements is performed easily, and the rejection rate of pipes is reduced. The processing cost of the pipes is reduced, and the yield of the pipes is increased; furthermore, the operation for processing the pipes is subdivided, so that the standardized and normalized development of the pipes is promoted; and popularization of the pipes is facilitated.

Description

Double-wall corrugated pipe straight tube jointing clip structure

Technical field

The utility model relates to the structure that a kind of double-wall corrugated pipe straight tube connects, and especially relates to a kind of double-wall corrugated pipe straight tube jointing clip structure that can reduce processing cost, retrofit link, standard industry index.

Background technique

As shown in Figure 1 in existing technology, the cast of double-wall corrugated pipe straight tube 2 processes a bellmouth root 3 for band bellmouth 1 pattern between bellmouth 1 and the double-wall corrugated pipe straight tube 2.When tubing in course of working; Bellmouth 1 part will be passed through speed-change process, and this process has increased mechanical coefficient of losses, and defective appears in tubing bellmouth 1 easily; Because the newspaper of a large amount of tubing that bellmouth 1 defective causes decreases, strengthened the newspaper loss rate of the central tubing of course of working and follow-up use.

Summary of the invention

It is low that the problem that the utility model will solve provides a kind of processing cost, and the double-wall corrugated pipe straight tube jointing clip structure of the use up-to-standard rate of the tubing that can guarantee to dispatch from the factory.

For solving the problems of the technologies described above; The technological scheme that the utility model adopts is: a kind of double-wall corrugated pipe straight tube jointing clip structure, comprise double-wall corrugated pipe straight tube, link, and said double-wall corrugated pipe straight tube port is level and smooth; Do not have bellmouth, the double-wall corrugated pipe straight tube connects through link.

Said link is a clip spare; Said clip spare is two relative semi-archeds, and bolton is passed through at two ends, or is two relative semi-archeds; The one of which end flexibly connects; The other end is through bolton, and the flexible material of said clip spare built-in guarantees that double-wall corrugated pipe straight tube and clip spare are tightly connected.

Advantage and the good effect that the utlity model has are: owing to adopt technique scheme; Save the machining operation of bellmouth part in the middle of the production of double-wall corrugated pipe straight tube; Only produce straight-tube portion continuously; Thereby guaranteed mechanical stable operation, reduced the extra consume of machine, and can produce the tubing of random length.The double-wall corrugated pipe straight tube connects through link, produces connected element separately, carries out the normative operation of high requirement easily, thereby reduces tubing newspaper loss rate.Have the processing cost that reduces tubing, promote the up-to-standard rate of tubing, the machining operation of tubing is further segmented, promote the standardization and standardization development of tubing, help the advantages such as popularization of tubing.

Embodiment

Like Fig. 2,3, shown in 4; A kind of double-wall corrugated pipe straight tube of the utility model jointing clip structure comprises double-wall corrugated pipe straight tube 2, link, and said double-wall corrugated pipe straight tube 2 ports are level and smooth; Do not have bellmouth 1, double-wall corrugated pipe straight tube 2 connects through link.

Said link is a clip spare 4, and said clip spare 4 is two relative semi-archeds, and bolton is passed through at two ends; Or be two relative semi-archeds, the one of which end flexibly connects, and the other end passes through bolton; The profile of said clip spare 4 is the configuration designs of depending on double-wall corrugated pipe straight tube 2; Its outer wall 5 is a high tenacity outer wall 5, and the flexible material 6 of built-in guarantees that double-wall corrugated pipe straight tube 2 and clip spare 4 are tightly connected.

Said double-wall corrugated pipe straight tube 2 need not processed bellmouth 1, only produces straight-tube portion continuously, thereby has guaranteed mechanical stable operation, has reduced the extra consume of machine, and can produce the tubing of random length.

More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
