CN201891712U - Plastic connecting plug of bracket - Google Patents

Abstract

The utility model discloses a plastic connecting plug of a bracket, which is assembled between a connecting pipe and a left support and a right support. Jacks I are formed at two ends of the connecting pipe; jacks II are formed at connecting ends of the left support and the right support; and the plastic connecting plug is provided with plug pins I tightly matched with the jacks I and plug pins II tightly matched with the jacks II; air discharge grooves are formed on surfaces of the plug pins I and the plug pins II; and chip grooves are formed between the plug pins I and the plug pins II. As the plastic connecting plug is added in a position where the left support, the right support and the connecting pipe are assembled and matched, the plastic connecting plug is not required to be plated, dimensional change after plating is avoided, the fit tightness between the plug pins I and the jacks I and the fit tightness between the plug pins II and the jacks II are identical, and firm connection between the connecting pipe and the left support and the right support is ensured.

Description

The plastic cement connection plug of support

Technical field

The utility model relates to a kind of support, and is special relevant with the structure of its plastic cement connection plug.

Background technique

In the prior art, the structure of support is made up of connecting tube 10, left support abutment 20 and right support abutment 30 roughly as shown in Figures 1 to 4.Two ends at connecting tube 10 directly form jack 40 by mould.Connecting end at left support abutment 20 and right support abutment 30 directly forms inserting column 50 by mould.

Because it all is to be come out by the mould rheo-die-casting with jack 40 that support connects the inserting column 50 of cooperation position, in the time of assembling, cooperate with jack 40 by inserting column 50, the two ends of connecting tube 10 directly are enclosed within on left support abutment 20 and the right support abutment 30, even connecting tube 10 is connected and fixed with left support abutment 20 and right support abutment 30, constitute complete support.

But the cooperation position of support is in die casting and electroplating process, and size and burr are difficult to control, and in assembling connecting tube 10, degree of tightness differs, sometimes even can't assemble.

In view of this, the inventor studies the structure of existing support, and this case produces thus.

The model utility content

The purpose of this utility model is to provide a kind of plastic cement connection plug of support, to realize that connecting tube is connected with the firm of left support abutment, right support abutment.

To achieve these goals, the technical solution of the utility model is:

A kind of plastic cement connection plug of support, be assembled between connecting tube and left support abutment and the right support abutment, the two ends of connecting tube form jack one, and the connecting end of left support abutment and right support abutment forms jack two, the plastic cement connection plug have with jack one friction tight inserting column one and with jack two friction tight inserting columns two.

The surface of described inserting column one and inserting column two forms air vent, so that exhaust during assembling avoids the air pressure relation to cause the plastic cement connecting sleeve can't be assembled in left support abutment and the right support abutment.

Form groove between described inserting column one and the inserting column two,, avoid burr to influence matching gap so that take in the burr that push out on plastic cement connecting sleeve surface when assembling.

After adopting said structure, in the utility model when assembling, is in the fastening jack one that is plugged on connecting tube of the inserting column one of plastic cement connection plug, in the fastening jack two that is plugged on left support abutment or right support abutment of inserting column two, even connecting tube and left support abutment and right support abutment are connected and fixed, constitute complete support.

The utility model increases a plastic cement connection plug because of the assembling cooperation position at left support abutment, right support abutment and connecting tube, this plastic cement connection plug does not need to electroplate, avoid electroplating the variation of back size, inserting column one is consistent with the elasticity that cooperates of jack two with jack one, inserting column two, guarantees that connecting tube is connected with the firm of left support abutment, right support abutment.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Embodiment

To shown in Figure 9, the plastic cement connection plug of a kind of support that the utility model discloses is assembled between connecting tube 1 and left support abutment 2 and the right support abutment 3 as Fig. 5.Connecting tube 1 two ends of support form jack 1, and the connecting end of left support abutment 2 and right support abutment 3 forms jack 25.Plastic cement connection plug 6 of the present utility model have with jack one 4 friction tight inserting columns 1 and with jack 25 friction tight inserting columns 2 62.The surface of inserting column 1 and inserting column 2 62 also forms air vent 63.Also form groove 64 between inserting column 1 and the inserting column 2 62.

During the utility model assembling, in the fastening jack 1 that is plugged on connecting tube 1 of the inserting column 1 of plastic cement connection plug 6, in the fastening jack 25 that is plugged on left support abutment 2 or right support abutment 3 of inserting column 2 62, because plastic cement connection plug 6 does not need to electroplate, avoid electroplating the variation of back size, inserting column 1 is consistent with the elasticity that cooperates of jack 25 with jack 1, inserting column 2 62, guarantees that connecting tube 1 is connected with left support abutment 2, the firm of right support abutment 3, constitutes complete, firm support.

Wherein, the major function of air vent 63 is: when avoiding assembling, because of the air pressure relation, cause plastic cement connecting sleeve 6 can't be assembled in left support abutment 2 and the right support abutment 3.

The major function of groove 64 is: when plastic cement connection plug 6 was enclosed within on connecting tube 1 and left support abutment 2, the right support abutment 3, the burr of avoiding plastic cement connecting sleeve 6 surfaces to push out influenced matching gap.

It below only is preferred implementation of the present utility model; it is not qualification to protection domain of the present utility model; key technology all and of the present utility model does not have to produce difference in essence, to the deduction or replace of above-mentioned mode of execution, all should be regarded as falling within the protection domain of this case.
