Abstract
The utility model discloses a jointing sleeve, comprising a sleeve body and an isolator in the sleeve body, wherein the sleeve body comprises two conical tubes whose bottoms are butted and the isolator is provided between the two conical tubes; the two conical tubes are respectively provided with an internal sliding tube which can slide along the inner walls of the conical tubes; the inner walls of the sliding tubes are cylinder; and two springs are mounted between the isolator and the sliding tubes. When in use, users should inserts the steel bars or steel tubes to be connected into the sliding tubes, select connecting sleeves of the type corresponding to the diameters of the steel bars or the steel tubes, tightly combine the inner walls of the sliding tubes with the steel bars or the steel tubes via the support function of the springs, and connect the two steel bars or steel tubes via the friction force between the steel bars or the steel tubes and the sliding tubes. The joint sleeve can be detached simply to be used again.
Description
Technical field
The utility model relates to a kind of splicing sleeve that is used to overlap reinforcing bar or steel pipe.
Background technology
In the engineering construction process, there are many temporary buildings to build.Sometimes need in the build process of temporary building reinforcing bar or steel pipe are overlapped temporarily, way commonly used adopts butt welding.The butt welding of reinforcing bar or steel pipe need be unfavorable for saving the quick construction of cost and engineering with equipment such as butt welding machine or electric welding machines, and can not dismantle after the welding and re-use.
The utility model content
The technical problems to be solved in the utility model provides a kind of splicing sleeve that is specifically designed to overlap joint reinforcing bar or steel pipe.
For solving the problems of the technologies described above, the splicing sleeve that is provided, comprise body and be contained in the interior partition of body, its design feature is: described body is two conically shapeds of bottom butt joint, partition is between two conically shapeds, being respectively equipped with in two conically shapeds can be along the slide cartridge of conically shaped inwall slip, and the inwall of slide cartridge is cylindrical, between described partition and the slide cartridge spring is housed.
After adopting said structure, body is two conically shapeds of bottom butt joint, being respectively equipped with in two conically shapeds can be along the slide cartridge of conically shaped inwall slip, the inwall of slide cartridge is cylindrical, between partition and the slide cartridge spring is housed, the reinforcing bar or the steel pipe of needs overlap joint can be injected in the slide cartridge, select the splicing sleeve of respective model according to the diameter of reinforcing bar or steel pipe, supporting role by spring is combined closely slide cartridge inwall and reinforcing bar or steel pipe, makes two sections reinforcing bars or steel tube lapping together by both frictional force.The utility model is simple in structure, can overlap various reinforcing bars or steel pipe fast, and can reuse by convenient disassembly.
Offer elongated slot on the described tube body wall, be connected with T shape sliding handle on the slide cartridge, sliding handle passes the outside that elongated slot is exposed at body.
As improvement of the present utility model, the inwall of described slide cartridge is provided with anti-skidding thorn, can increase the frictional force of slide cartridge inwall and reinforcing bar or steel pipe, has strengthened the tensile strength behind the overlap joint.
Description of drawings
The structural representation that Fig. 1 analyses and observe for the utility model;
The structural representation that Fig. 2 analyses and observe for slide cartridge;
Among the figure: 1 is body, and 2 for cutting off, and 3 is slide cartridge, and 4 is sliding handle, and 5 is elongated slot, and 6 is spring, and 7 is anti-skidding thorn, and 8 is reinforcing bar.
The specific embodiment
Splicing sleeve as shown in drawings, it comprises body 1, body 1 is two conically shapeds of bottom butt joint, is equipped with between two conically shapeds to cut off 2, cuts off 2 intensity that can strengthen body 1; Being respectively equipped with in two conically shapeds can be along the slide cartridge 3 of conically shaped inwall slip, the inwall of slide cartridge 3 is cylindrical, offer elongated slot 5 respectively on the two taper barrels, be fixed with two T shape sliding handles 4 on the symmetric position of slide cartridge 3 external surfaces, sliding handle 4 passes the outside that elongated slot 5 is exposed at body 1 conically shaped, symmetry is equipped with two springs 6 between partition 2 and each slide cartridge 3, and the inwall of slide cartridge 3 is provided with the incline direction anti-skidding thorn 7 opposite with reinforcing bar 8 direction of insertion.
This splicing sleeve is to use like this: under the inactive state, spring 6 can withstand slide cartridge 3 to from the position that cuts off 2 maximum distances, and at this moment, the internal diameter minimum of slide cartridge 3 is the minimum diameters that can overlap reinforcing bar 8; When spring 8 is compressed to the limit, slide cartridge 3 moves to from the position that cuts off 2 minimum distances, and at this moment, the internal diameter maximum of slide cartridge 3 is the maximum gauges that can overlap reinforcing bar 8.Drive slide cartridge 3 near cutting off 2 by sliding handle 4 earlier, compress spring 6 this moment, the reinforcing bar 8 of suitable diameter is filled in the slide cartridge 3, discharge sliding handle 4, make slide cartridge 3 tightly embrace reinforcing bar 8 in the process that spring 6 resets, anti-skidding thorn 7 can further strengthen the frictional force between slide cartridge 3 inwalls and the reinforcing bar 8, thereby realizes the fastening overlap joint of two end bars 8.
