Abstract
The utility model provides a novel taper sleeve locking type connector, which mainly comprises an inner sleeve and an outer sleeve, wherein the inner sleeve and the outer sleeve are locked through conical surfaces, the inner sleeve adopts a split type structure and consists of two or more inner sleeve piece circumferential arrays, the inner cylinder wall of the inner sleeve is provided with protruding teeth for clamping reinforcing steel bars, and the protruding teeth are clamped into the reinforcing steel bars after the outer sleeve and the inner sleeve are pressed by a pressure device.
Description
Technical Field
The utility model relates to the technical field of steel bar connection in buildings, in particular to a novel taper sleeve locking type connector.
Background
Application number: 200820300434.3, name: the split joint sleeve is disclosed in the utility model application as the closest prior art to the present application. The following technical defects exist: the locking mode of double-end locking sleeve is adopted in the technical scheme, the lower locking sleeve needs to be manually held in the locking operation process, otherwise, the lower locking sleeve is easy to fall off; the inner wall of the sleeve is provided with threads, the threads are easy to generate staggered teeth when the split sleeve is combined with the sleeve, and the split sleeve is not smooth when screwed into the steel bar; in addition, threads are required to be machined at the end part of the steel bar to be matched with the sleeve, so that the production process and the cost are increased.
Disclosure of Invention
The utility model aims at overcoming the defects in the technology, and provides a novel taper sleeve locking type connector which is simple in structure and convenient to operate.
The purpose of the utility model is realized in the following way: the novel inner sleeve comprises an inner sleeve and an outer sleeve, wherein the inner sleeve is sleeved with the outer sleeve, the inner sleeve consists of two or more inner sleeve pieces in a circumferential array, the outer cylindrical surface of the inner sleeve is a conical surface, and an inner hole is provided with convex teeth; the inner hole surface of the outer sleeve is a conical surface;
further, one or more grooves are formed in the outer cylindrical surface of the inner sleeve, and rubber rings are arranged in the grooves;
further, the taper range of the inner hole surface of the outer sleeve and the outer cylindrical surface of the inner sleeve is 1-20 degrees, so that the novel taper sleeve locking type connector is formed.
The utility model has the beneficial effects that: the structure is simple, the operation is convenient, the inner hole of the inner sleeve is provided with the convex teeth, when the hydraulic equipment tightly presses the outer sleeve and the inner sleeve, the convex teeth can be clamped into the steel bars, the steel bars are prevented from falling off, the steel bars with or without threads can be clamped, and the procedure of processing threads by the steel bars is omitted;
the outer cylindrical surface of the inner sleeve is provided with a groove and a rubber ring, the split type inner sleeve is sleeved on the steel bar, the rubber ring can provide holding force to prevent the inner sleeve from falling off, the inner sleeve does not need to be held by hands in the compression process, and the injury of workers is avoided.
Description of the drawings:
FIG. 1 is an exploded pictorial view of the present utility model;
FIG. 2 is a schematic cross-sectional view of the present utility model;
fig. 3 is a schematic cross-sectional view of fig. 2 A-A.
Detailed Description
The present embodiment will be further described with reference to the accompanying drawings
Referring to fig. 1-3, the novel inner sleeve comprises an inner sleeve 2 and an outer sleeve 1, wherein the inner sleeve 2 is sleeved with the outer sleeve 1, the inner sleeve 2 is formed by two or more circumferential arrays of inner sleeve pieces 201, the outer cylindrical surface of the inner sleeve 2 is a conical surface, and a convex tooth 203 is arranged in an inner hole; the inner hole surface of the outer sleeve 1 is a conical surface 101, wherein the taper range of the inner hole surface of the outer sleeve 1 and the outer cylindrical surface of the inner sleeve 2 is 1-20 degrees, one or more grooves 202 are formed in the outer cylindrical surface of the inner sleeve 2, and rubber rings 3 are arranged in the grooves 202.
Principle of operation
The installation steps are as follows when in use: firstly, the rubber ring 3 is sleeved in the groove 202 of the inner sleeve, the inner sleeve piece 201 is tightly held to be cylindrical to form a complete inner sleeve 2, the inner sleeve 2 is sleeved at the joint of two steel bars to be connected, then the outer sleeve 1 is sleeved outside the inner sleeve 2, the two end faces of the inner sleeve and the outer sleeve are respectively abutted by using a hydraulic pressure equal pressure device, the pressure device is driven, after pressure is applied between the outer sleeve and the inner sleeve, the outer sleeve moves towards the inner sleeve direction and generates interference fit with the inner sleeve, when the outer sleeve moves, the diameter of the inner sleeve is gradually reduced, protruding teeth of an inner hole of the inner sleeve are clamped into the surface of the steel bars and play a role of fixed connection, and when the outer sleeve moves to be basically coincident with the end faces of the inner sleeve or the pressure value of pressure equipment reaches a preset value, the installation is completed.
Claims (3)
1. The novel taper sleeve locking type connector comprises an inner sleeve and an outer sleeve, and is characterized in that the inner sleeve and the outer sleeve are sleeved and in interference fit, the inner sleeve consists of two or more inner sleeve piece circumferential arrays, the outer cylindrical surface of the inner sleeve is a conical surface, and convex teeth are arranged in an inner hole; the inner hole surface of the outer sleeve is a conical surface.
