Description
Technical field
The present invention is that pipe fitting is used in a kind of pipeline connection, is specifically related to clamping and pressing fitting.
Background technique
Aluminium-plastic composite pipe is as a kind of novel tube, and development at home and abroad rapidly.At present, the supporting pipe fitting of domestic aluminium-plastic composite pipe is various informative, adopted tongs press type to be connected by comparatively ripe with the safe pipe fitting Placement of social recognition, the pipe box that soon can clamp compressive strain is inserted in aluminium-plastic composite pipe tubing connection mouth external diameter, the pipe fitting of pipe inner support and interconnect function is housed at tubing connection mouth internal diameter simultaneously, by instrument clamper tube cover, make pipe box be out of shape again, realization is fixedlyed connected with tubing.The tongs press type Placement on being applied in aluminium-plastic composite pipe, but can also be applied in that steel is moulded, on Copper-plastic Composite Pipe pipe fitting and other the clamper tube spares.
Prior art such as Figure of description are shown in Figure 1, for being pressed, pincers are in place reliably, be provided with an annular boss 4 ' that is not less than attachment portion 2 ' maximum outside diameter at the attachment portion of pipe fitting 1 ' 2 ' bottom end 3 ', on annular boss 4 ', be provided with an annular groove 5 '.One deck 6 ' is realized and the fixedlying connected of pipe fitting 1 ' by the bulge loop that cooperates with annular groove 5 ' that is provided with on its internal diameter 7 '; The stretch out toroidal extension 9 ' of band grab a 8 ' structure of deck 6 ' front-end face, the effect of toroidal extension 9 ' is to cooperate with pipe box 10 ', and, realize fixedlying connected of pipe box 10 ' and deck 6 ' by the fixing of part 11 ' that contract in grab 8 ' and the pipe box 10 ' front end.Structure similar to the above also just like the clamp-press type aluminium-plastic composite pipe pipe fitting of patent announcement CN 2839784Y.In tongs press type connects, include a deck, help the location and installation of pipe box, pipe box can not produce the problem of positioning, decentraction because of the effect of pincers pressure, improves installation reliability.In the tradition clamping and pressing fitting, deck all is a complete loop configuration, for deck being installed into link bottom end and fixing, all design an annular boss that is not less than attachment portion external diameter size at the pipe fitting bottom end, increased the pipe fitting material consumption like this; And after the pipe fitting pincers press fit, owing to the reason that deck is spacing can't be dismantled, this will make the pipe fitting of improper installation to reuse, and increase installation cost.
Summary of the invention
The present invention is directed to the defective on the clamping and pressing fitting of above-mentioned existing band deck, a kind of novel clamping and pressing fitting is provided, and this clamping and pressing fitting has improved the structure of deck, and the pipe fitting structure that deck is supporting is improved, solve the problem that prior art exists, had better practicability.
For achieving the above object, the present invention is by the following technical solutions:
A kind of clamping and pressing fitting with opening holder, comprise a pipe fitting, one is installed in the deck of pipe fitting attachment portion bottom end, one is assemblied on the pipe fitting and the pipe box that cooperates with deck, it is characterized in that: described bottom end is provided with an annular groove, one nicked deck is installed in the annular groove by the elasticity fastening force, and described deck is a plastic materials.
The present invention program can also be:
Above-mentioned deck front-end face has a toroidal extension, and toroidal extension is provided with part or all of hook structure, and the pipe box that contracts in the front end is played fixation.
Above-mentioned deck adopts the PP material.
Above-mentioned deck otch is ladder.
Above-mentioned pipe fitting adopts the PPSU plastic materials.
The clamping and pressing fitting of band opening holder of the present invention, deck has elasticity, and it is provided with otch, and is easy to assembly as long as the deck otch is widened the groove that can be inserted in the pipe junctor, and is subjected to the attachment portion external diameter size of pipe fitting to influence little.After the pipe fitting pincers are pressed, also convenient the disengaging, directly widen the deck otch, deck is taken out along pipe fitting axle center Vertical direction, make pipe box lose the spacing constraint on pipe fitting, easily pipe box is pulled out.Can make pipe fitting reuse like this, the pipe of connection can not be damaged yet, and realizes the recovery of pipe fitting parts, reduces installation cost, has advantages of high practicability.

Embodiment
Extremely shown in Figure 4 as Fig. 2, a kind of clamping and pressing fitting of the present invention with opening holder, comprise a pipe fitting 1, one is installed in the deck 2 of pipe fitting 1 attachment portion 10 bottom ends 11, one is assemblied on the pipe fitting 1 and the pipe box 3 that cooperates with deck 2, the deck 2 that bottom end 11 is provided with an annular groove 12, one band otch 20 is installed in the annular groove 12 by the elasticity fastening force.Above-mentioned clamping and pressing fitting can be directly, is that reducing is direct as Fig. 2, also elbow, threeway, internal thread tube piece etc., and at least one end adopts the tongs press type mounting type to connect, and the tubing of tongs press type has tubing such as aluminium-plastic composite pipe, steel-plastic composite pipe at present.
Pipe fitting of the present invention, its deck 2 front ends have a toroidal extension 21, and toroidal extension 21 is provided with hook structure 22, and hook structure 22 can be whole annular snap hook structures, as shown in Figure 6, the part annular snap hook structure that also can be, as shown in Figure 5.Hook structure 22 can play fixing effect with the part 30 that contracts in the front end of pipe box 3.
Above-mentioned deck 2 its otch 20 are stepped shaft, as shown in Figure 4.Also can being aligned shape, as shown in Figure 5, or an inclined plane shape, as shown in Figure 6, otch 20 forms can be various, satisfies and elastic clamp seat 2 can be drawn back along otch 20.
Above-mentioned deck 2 can adopt plastic materialss such as PP, PVC, nylon to make.
Above-mentioned pipe fitting 1 can adopt metallic material such as copper, brass to make, and also can adopt plastic materialss such as PPSU, PSU, nylon to make.
Above-mentioned pipe box 3 is metallic material such as stainless steel, steel, has certain intensity and deformation performance, to satisfy the pincers pressure request.
When pipe fitting is installed, as long as the otch of deck 2 is widened, be inserted in the annular groove 12 of pipe fitting 1 and get final product, the mode that need penetrate from the attachment portion of pipe fitting and fix by tolerance fit with respect to traditional deck, have characteristics easily are installed, be more suitable for automation production is installed.The change of the mounting type of deck in addition makes that the structure of pipe fitting is simpler, and the energy-conservation material of using has reduced cost of production more than 5%; In piping erection, this structure also is convenient to the utilization again of pipe fitting unloading back part, has higher utility simultaneously.
