Abstract
The utility model discloses a pipe piece detachable quick joint which comprises a detachable end part, a check washer and a pre-buried base body. The embedded base body lower part is the platykurtic, and upper portion has the internal thread hole, can dismantle tip one end has the external screw thread, and the other end has the back taper structure, can dismantle tip external screw thread and embedded base body internal thread connection, it is locking to fasten through increasing locking gasket, the back taper connects and carries out the high-speed joint with the female head that matches. The base member is pre-buried in the section of jurisdiction preparation process, and the back will be dismantled the tip and pass through the screw thread and install on the base member before section of jurisdiction equipment after the preparation finishes, can dismantle the back taper structure that tip other end has and can carry out the high-speed joint with the quick-operation joint female head that matches, reach quick installation effect. The utility model can quickly realize duct piece connection and reduce the operation difficulty. The construction efficiency can be greatly improved, and the working period can be shortened. And the labor intensity of constructors can be reduced. The cost is greatly reduced. Meanwhile, the problem that the quick joint protrudes out of the segment to cause collision and abrasion of the quick joint in the segment carrying process and cause installation mismatching can be avoided.
Description
Technical Field
The utility model relates to the field of spare and accessory parts for constructional engineering, in particular to a detachable quick connector.
Background
The existing shield segment installation technology is mainly based on U-shaped screw nut installation. After the required pipe pieces are aligned, the U-shaped screw rods are inserted, and the mounting nuts are fixed. However, in the actual operation process, the duct pieces are difficult to align, the U-shaped screw rod is difficult to insert during installation, and multiple times of adjustment are needed. And may cause some damage to the tube sheet. The whole installation is difficult and the installation is not easy. The labor cost is high, and the construction period is long.
At present, the scheme of the quick joint in the shield segment market in China is blank, and the problem of the existing U-shaped screw nut scheme is urgently to be solved. To this end, we propose a new structure of detachable quick coupling to solve the above-mentioned problems. On the basis of solving the installation problem fast, can dismantle again, avoid the collision wearing and tearing problem in the handling.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects in the prior art and provides a quick connector capable of detaching a tube sheet.
In order to achieve the purpose, the utility model adopts the following technical scheme: a detachable quick connector comprises a detachable end part, a locking gasket and a pre-buried base body. The lower part of the embedded base body is flat, and the upper part of the embedded base body is provided with an internal thread hole. One end of the detachable end part is provided with an external thread, and the other end of the detachable end part is provided with an inverted cone structure. The detachable end part external thread is connected with the embedded base body internal thread hole, and fastening and looseness prevention are carried out by increasing the anti-loosening gasket. The detachable end inverted cone structure is quickly connected with the matched female head. The base body is pre-buried in the duct piece manufacturing process, and the detachable end part is installed on the base body through threads before the duct piece is assembled after the duct piece is manufactured. Can dismantle back taper structure that tip other end had and can carry out the high-speed joint with the quick-operation joint female head of matching, reach quick installation effect. According to the scheme, the segment connection can be realized quickly, and the operation difficulty is reduced. The construction efficiency can be greatly improved, and the working period can be shortened. And the labor intensity of constructors can be reduced. The cost is greatly reduced. Meanwhile, the problem that the quick joint protrudes out of the segment to cause collision and abrasion of the quick joint in the segment carrying process and cause installation mismatching can be avoided.
Drawings
Fig. 1 is a view of a detachable quick coupling structure of a duct piece.
In fig. 1: 1. can dismantle tip, 2, locking gasket, 3, pre-buried base member, 4, back taper structure, 5, external screw thread, 6, internal thread hole.
Detailed Description
The pre-buried base member all adopts stainless steel with can dismantle the tip.
In the figure, pre-buried base member (3) are pre-buried in the concrete segment, can directly carry, and the transportation is connected the operation when the section of jurisdiction is connected, and it is connected with external screw thread (5) that can dismantle tip (1) one end through inside internal thread hole (6) in pre-buried base member (3) upper end, and it is locking to add locking gasket (2) to fasten during the connection, can dismantle tip (1) other end and have back taper structure (4), and it carries out the high-speed joint with the female head of quick-operation joint who matches.
Compared with the prior art, the utility model has the beneficial effects that:
1. the pre-buried base member in the utility model all adopts stainless steel with can dismantling the tip, and the corrosion resistance is strong, and fatigue endurance is effectual, and each item performance test data is stable, can satisfy various service environment requirements.
2. The detachable quick connector structure in the utility model is symmetrical, so that the quick connector is uniform in all directions and firm and durable in use when stressed.
3. The quick-operation joint simple operation dismantled in this practicality can improve the efficiency of construction greatly, shortens the operation time limit for a project. And the labor intensity of constructors can be reduced. The cost is greatly reduced.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
