CN203686414U - Spalling-preventing pipe clamping hoop - Google Patents

Abstract

The utility model discloses a spalling-preventing pipe clamping hoop which comprises a semi-arc main pipe clamping piece and an auxiliary pipe clamping piece. The main pipe clamping piece and the auxiliary pipe clamping piece are buckled with each other. Auxiliary sides are arranged on the two sides of the main pipe clamping piece and the two sides of the auxiliary pipe clamping piece respectively. The wall thickness of the auxiliary sides is larger than the wall thickness of the arc parts of the main pipe clamping piece and the auxiliary pipe clamping piece. Thread through holes are formed in the auxiliary sides of the main pipe clamping piece. A clamping base for fixing is arranged in the middle of the main pipe clamping piece. The inner walls of the main pipe clamping piece and the auxiliary pipe clamping pipe are respectively provided with at least one elastic protrusion. The spalling-preventing pipe clamping hoop has the advantages that a pipe fitting can be well combined in an embracing mode through a pipe camp, so that the pipe clamp and the pipe wall are in tight and stable contact, and mounting difficulty caused by the fact that a nut is arranged on the back face of the main pipe clamping piece to fasten a screw is avoided.

Description

Expansion cracking proof pipe clip

Technical field

The utility model relates to pipe clamp technical field, relates in particular to a kind of expansion cracking proof pipe clip.

Background technique

The problems such as pipe clamp is the conventional pipe fitting for fixing tube during hot-water heating is installed, and in practice, needs to pacify dress ﹑ convenient disassembly, and what external environment caused expands with heat and contract with cold and premature aging, and pipe clamp and pipe engaging are tight.

Chinese utility model patent CN202972206U discloses a kind of Drop-proof band cushion course pipe clamp, and this Novel pipe clamp can effectively address the above problem.Described Drop-proof band cushion course pipe clamp, there are involutory main body dimerous and two-part main body locking mechanism, two-part main body forms circular arc after locking and clamp pipe fitting, one of two-part main body is greater than semi-circular arc, be attached with cushion course at two-part body inner surface, and the main body that is greater than semi-circular arc is exceeding the circular arc inside line of semicircle, be fixedly connected with the right hard card of left ﹑ prominent, the chord length between left and right hard card is prominent be less than adhere to after cushion course in the diameter of circular arc.The pipe clamp of this novel structure utilizes the elasticity of material and circular arc conveniently to clamp pipe fitting, makes pipe clamp obvolvent pipe fitting well.But the deficiency that adopts the pipe clamp of this technological scheme to exist is: complex structure, and raw material use more, and when construction, An Zhuan ﹑ dismounting is inconvenient.

For above-mentioned the deficiencies in the prior art, the present utility model people has proposed a kind of expansion cracking proof pipe clip.

Model utility content

The utility model provides a kind of expansion cracking proof pipe clip, can effectively solve complex structure, and raw material use more, when construction peace dress ﹑ dismounting inconvenient, the problem such as what external environment caused expand with heat and contract with cold and make pipe clamp premature aging, and pipe clamp and pipe engaging are not tight.

The technical problem that the utility model solves realizes by the following technical solutions.

Expansion cracking proof pipe clip, comprises that the semicircle arcuation of mutual fastening is responsible for card and looped pipeline card, be respectively equipped with secondary, and the wall thickness of described secondary is greater than the wall thickness at described supervisor's card and looped pipeline card circular arc position in the both sides of described supervisor's card and looped pipeline card;

On the secondary of described supervisor's card, be provided with tapped through hole;

Be provided with for fixing deck at the middle part of described supervisor's card;

On the inwall of described supervisor's card and looped pipeline card, be also provided with more than one elastic bumps.

Further, every group of described elastic bumps is made up of 4 above triangles.

Further, there is rounding on the top of described elastic bumps.

This advantage is:

1). in work progress, peace dress ﹑ convenient disassembly.

2). the tight close ﹑ of engaging of pipe clamp and pipe fitting is firm, prevents that pipe fitting from coming off.

3). delay pipe clamp because of the premature aging that expands with heat and contract with cold outward.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is expansion cracking proof pipe clip structural representation described in the utility model.

Fig. 2 is the partial enlarged drawing at A place in Fig. 1.

In figure, 1. supervisor's card, 2. looped pipeline card, 3. deck, 4. secondary, 5. tapped through hole, 8. bolt, 9. elastic bumps.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Shown in Fig. 1, expansion cracking proof pipe clip of the present utility model comprises deck 3 ﹑ supervisor's card 1 and looped pipeline cards 2, deck 3 is arranged on supervisor's card 1, the both sides of supervisor's card 1 and looped pipeline card 2 are respectively equipped with secondary 4, on the secondary 4 of supervisor's card 1, be provided with tapped through hole 5, so that supervisor's card 1 and looped pipeline card 2 fixing pipeline.In order to guarantee the intensity of clip, the thickness of secondary 4 is greater than the thickness of supervisor's card 1 and looped pipeline card 2.On the inwall of supervisor's card 1 and looped pipeline card 2, be respectively provided with more than one elastic bumps 9.When pipe clamp is installed, deck 3 at right angle settings, in metope, are fixed pipe clamp.Bolt 8 screws in tapped through hole 5, and this fastening means has been abandoned conventional tube and has been stuck in the back scheme of nut lockk bolt of being responsible for card, has greatly reduced An Zhuan ﹑ dismounting difficulty.

Every group of elastic bumps 9 is made up of 4 above triangles, improves the frictional force of protruding 9 and outer surface of pipe fittings of elasticity.

There is rounding on the top of elastic bumps 9, the top of avoiding elastic bumps 9 too tapering and with the engaging process of pipe fitting in cause bending, affect the elastic force of elastic bumps.

More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
