Description

Technical Field

[0001] The utility model relates to the technical field of steel bar connection, in particular to a sleeve type steel bar connection device. Background Art

[0002] In construction projects, steel bars are an important element that constitutes the skeleton of a building, so the stability and reliability of the connection between steel bars are crucial to the safety of the entire building.

[0003] In order to facilitate the connection of steel bars, a ferrule connection method was initially used to connect the steel bars at both ends, and then a connecting device was used to fix the connection between the two. However, in actual use, the steel bar connection distance is prone to uncertainty, so that the traditional ferrule device cannot adapt well to the positioning connection. Utility Model Content

[0004] In order to solve the technical problem that the distance between two groups of steel bars is uncertain when they are connected, resulting in the inability of the equipment to be well connected and fixed, the utility model provides a sleeve-type steel bar connection device.

[0005] The utility model is implemented by the following technical scheme: a sleeve type steel bar connection device, comprising a mother piece, one end of the mother piece is limited by a steel bar piece, and a limiting mechanism is arranged near the steel bar piece on the mother piece;

[0006] A sub-component, one end of which is limited by another set of steel bars, and a second limiting mechanism is provided near the other set of steel bars on the sub-component;

[0007] The connecting mechanism is respectively arranged at the positions where the mother component and the child component are close to each other. The connecting mechanism includes a mother component and a child component, and the two are respectively arranged at the mother component and the child component.

[0008] Through the above technical scheme, two sets of limiting mechanisms are used to fix the steel bars to be connected at both ends respectively, and then the two sets of steel bars are adaptively connected with the cooperation of the connecting mechanism. When there is a certain error between the two, the connecting mechanism can be used to elastically adapt to abut against each other and lock them under rotation.

[0009] As a further improvement of the above scheme, the limiting mechanism includes a fixed sleeve, which is installed at one end of the mother part. The outer wall of the fixed sleeve is provided with a thread, and the fixed sleeve is threadedly connected with a nut. The outer wall of the fixed sleeve is symmetrically provided with vertical notches, and the inner wall of the fixed sleeve is evenly provided with protrusions to increase the limiting force with the steel bar.

[0010] As a further improvement of the above scheme, the second limiting mechanism includes a second fixed sleeve plate, which is installed at one end of the sub-component, and the outer wall of the second fixed sleeve plate is provided with a thread, and the outer wall of the second fixed sleeve plate is symmetrically provided with vertical notches, and the second fixed sleeve plate is threadedly connected with a second nut, and the inner walls of the second fixed sleeve plate are evenly provided with protrusions to increase the limiting force with the steel bar.

[0011] Through the above technical solution, the steel bar is first sleeved, and then the connection between the corresponding nut and the fixed sleeve is adjusted. As the nut rotates outward, the fixed sleeve will be squeezed inward, and the protrusion will be driven to further fix with the steel bar.

[0012] As a further improvement of the above solution, the mother component and the child component are both hollow so as to be used for sleeve installation and fixation of the reinforcement component.

[0013] As a further improvement of the above scheme, the female component includes a spring chamber 1 opened at the other end of the female component, a spring 1 is fixedly connected in the spring chamber 1, a slide 1 is fixedly connected to the other end of the spring 1, a connecting sleeve block is rotatably connected to the other end of the slide 1, the connecting sleeve block can be vertically moved in the spring chamber 1 by means of the slide 1, and a plurality of groups of grooves are evenly arranged in the inner wall of the other end of the connecting sleeve block.

[0014] As a further improvement of the above scheme, the subassembly includes a spring chamber 2 opened at the other end of the sub-component, a spring 2 is fixedly connected in the spring chamber 2, a slide plate 2 is fixedly connected to the other end of the spring 2, and a convex plate is evenly fixedly connected to the other end of the slide plate 2, and multiple groups of the convex plates can slide in the slot and be fixed on the inner side of the slot.

[0015] Through the above technical solution, by utilizing the telescopic characteristics of the two, it will be possible to better adapt to the fixation of steel bars with different spacings, and because only vertical telescopic sliding is possible, the connection effect is further guaranteed.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The utility model utilizes the cooperation of the matching limiting mechanism and the connecting mechanism to quickly fix and limit two groups of steel bars, and can carry out adaptive activities with the cooperation of the parent and child components in the connecting mechanism to meet the needs of fixing steel bars with different spacings.

[0028] The connecting mechanism is respectively arranged at the positions where the mother component 1 and the child component 2 are close to each other. The connecting mechanism includes a mother component and a child component, and the two are respectively arranged at the mother component 1 and the child component 2.

[0029] The limiting mechanism includes a fixed sleeve 11, which is installed at one end of the mother part 1.

The outer wall of the fixed sleeve 11 is symmetrically provided with vertical notches, and the inner wall of the fixed sleeve 11 is evenly provided with protrusions to increase the limiting force with the steel bar 3.

[0030] The second limiting mechanism includes a second fixing sleeve 21, which is installed at one end of the sub-component 2. The outer wall of the second fixing sleeve 21 is provided with threads, and the outer wall of the second fixing sleeve 21 is symmetrically provided with vertical notches. The second fixing sleeve 21 is threadedly connected with a nut 22, and the inner wall of the second fixing sleeve 21 is evenly provided with protrusions to increase the limiting force with the steel bar 3.

[0031] Both the mother component 1 and the child component 2 are hollow, so as to be used for sleeve installation and fixation of the reinforcement component 3.

[0032] The implementation principle of a sleeve-type steel bar connection device in the embodiment of the present application is:

[0033] The fixing sleeve 11 and the fixing sleeve 21 at both ends of the mother component 1 and the sub-component 2 are respectively sleeved on the outer wall of the steel bar 3, and then the corresponding nuts 12 and 22 are rotated respectively. Under the threaded connection between the nuts 12 and the fixing sleeve 11, and the nuts 22 and the fixing sleeve 21, the fixing sleeve 11 and the fixing sleeve 21 can be gradually made closer to the corresponding steel bar 3 as they are rotated toward the outward end, and then the steel bar 3 can be further fixed and limited under the action of the convex action.

[0034] Embodiment 2:

[0035] Combination Figure 2-4 Based on Example 1, this embodiment is further improved in that:

[0036] The female component includes a spring chamber 13 opened at the other end of the female component 1, a spring 14 is fixedly connected in the spring chamber 13, a slide plate 15 is fixedly connected to the other end of the spring 14, a connecting sleeve 16 is rotatably connected to the other end of the slide plate 15, the connecting sleeve 16 can be vertically moved in the spring chamber 13 by means of the slide plate 15, and a plurality of groups of card grooves 17 are evenly arranged in the inner wall of the other end of the connecting sleeve 16.

[0037] The subassembly includes a spring chamber 23 opened at the other end of the subcomponent 2, a spring 24 is fixedly connected in the spring chamber 23, a slide plate 25 is fixedly connected to the other end of the spring 24, and a convex plate 26 is evenly fixedly connected to the other end of the slide plate 25. Multiple groups of convex plates 26 can slide in the slot 17 and be fixed on the inner side of the slot 17.

[0038] The implementation principle of this embodiment is:

[0039] When the distance between the two steel bars is large, after fixing the mother component 1 and the child component 2, the protruding plate 26 and the connecting sleeve 16 are held and pulled close to each other, so that the protruding plate 26 can slide to the innermost side along the slot 17. The connecting sleeve 16 rotatably connected to the slide plate 1 15 is rotated so that the protruding plate 26 slides to the inner side of the slot 17, and then the connecting sleeve 16 and the slide plate 2 25 are loosened, so that the two will rebound and shrink under the action of the corresponding springs, so that the protruding plate 26 will fall to the innermost side of the slot 17 for limiting, so as to achieve good adaptability of the equipment.

[0040] Working principle:

[0041] The fixing sleeve 11 and the fixing sleeve 21 at both ends of the mother component 1 and the sub-component 2 are respectively sleeved on the outer wall of the steel bar 3, and then the corresponding nuts 12 and 22 are rotated respectively. Under the threaded connection between the nuts 12 and the fixing sleeve 11, and the nuts 22 and the fixing sleeve 21, the fixing sleeve 11 and the fixing sleeve 21 can be gradually made closer to the corresponding steel bar 3 as they are rotated toward the outward end, and then the steel bar 3 can be further fixed and limited under the action of the convex action.

[0042] When the distance between the two steel bars is large, after fixing the mother component 1 and the child component 2, the protruding plate 26 and the connecting sleeve 16 are held and pulled close to each other, so that the protruding plate 26 can slide to the innermost side along the slot 17. The connecting sleeve 16 rotatably connected to the slide plate 1 15 is rotated so that the protruding plate 26 slides to the inner side of the slot 17, and then the connecting sleeve 16 and the slide plate 2 25 are loosened, so that the two will rebound and shrink under the action of the corresponding springs, so that the protruding plate 26 will fall to the innermost side of the slot 17 for limiting, so as to achieve good adaptability of the equipment.

[0043] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention.
