Description

Technical Field

[0001] This utility model relates to the field of rebar sleeve technology, and in particular to a quick-installation rebar combination sleeve. Background Technology

[0002] A rebar sleeve is a metal sleeve used to connect rebars. It is widely used in construction engineering and is mainly used for the mechanical connection of rebars. It can quickly combine two rebars together so that they can work together under stress, effectively transferring the tensile or compressive force of the rebars and ensuring the integrity and stability of the structure.

[0003] Currently, in practical use, workers insert the threaded end of the rebar into the sleeve and connect it by rotating the sleeve. However, due to the complex environment of construction sites, strong vibrations are generated when equipment such as concrete vibrators and pile drivers are in operation. These vibrations propagate through the foundation soil. If the rebar sleeve is close to the vibration point, the vibration can easily loosen the connection between the sleeve and the rebar, leading to stripping and failure of the rebar connection, which endangers the safety of the building structure. To address these issues, we propose a quick-installation rebar combination sleeve. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a quick-installation steel bar combination sleeve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quick-install rebar sleeve includes a fixed cylinder with threaded sleeves symmetrically welded to both ends. Threaded segments are inserted into the interior of each threaded sleeve. A rebar body is fixedly connected to the side of each threaded segment that is furthest from the others. A strip-shaped groove is formed inside the fixed cylinder, and an insertion strip is inserted into the groove. A positioning block is connected to the side of the insertion strip. An annular groove is formed at the end of each threaded segment, and a limiting groove adapted to the positioning block is formed on the inner wall of the threaded segment on the side of the annular groove. A connecting rod is connected to the side of the insertion strip, and a pulling block is provided at the other end of the connecting rod. An insertion rod is connected to the inner side of the pulling block. A rectangular groove adapted to the insertion rod is formed at the end of the connecting rod, and a slider is connected to the end of the insertion rod. A sliding track adapted to the slider is formed inside the connecting rod. A positioning rod is connected to the inner side of the pulling block. A slot adapted to the positioning rod is formed inside the fixed cylinder. A T-shaped groove adapted to the connecting rod and the pulling block is formed inside the fixed cylinder.

[0007] Preferably, the inner wall of the rectangular groove is connected to a connecting spring, and the other end of the connecting spring is connected to the side of the insertion rod.

[0008] Preferably, a U-shaped plate is fixedly connected to the side of the fixed cylinder, and a fixed shaft is connected to the inner wall of the U-shaped plate, and a cover plate is movably sleeved on the outer side of the fixed shaft.

[0009] Preferably, torsion springs are symmetrically connected to the sides of the cover plate, and the other end of the torsion springs is connected to the inner wall of the U-shaped plate.

[0010] Preferably, the side of the positioning block is glued with a rubber plate, and the rubber plate is set in an inclined shape.

[0011] Preferably, the outer wall of the threaded sleeve is connected to a rotating plate, and the rotating plate is distributed in a ring array structure on the outer surface of the threaded sleeve.

[0012] Preferably, the pull block is configured as a rectangular structure, and a groove is formed inside the pull block.

[0013] Preferably, the insertion strips are provided in two sets, and the two sets of insertion strips are symmetrically distributed about the central axis of the fixed cylinder.

[0014] Preferably, the cross-sectional area of ​​the cover plate is larger than the cross-sectional area of ​​the T-slot opening, and a buffer pad is glued to the inner side of the cover plate.

[0015] Preferably, the pull block is connected to two sets of positioning rods on its side, and the two sets of positioning rods are symmetrically distributed about the central axis of the pull block.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This device, equipped with insertion strips and positioning blocks, allows for lateral positioning of the threaded sections when both sets of threaded segments are fully inserted into the two sets of threaded sleeves. This, combined with the positioning blocks and limiting grooves, effectively prevents the threaded sections from slipping due to vibration during insertion, thus ensuring the reliability of the reinforcing bar body during assembly.

[0018] The device is equipped with a U-shaped plate and a cover plate. During use, the cover plate with a large cross-sectional area can cover the T-shaped opening inside the fixed cylinder, thereby effectively preventing foreign objects from entering the interior of the fixed cylinder and the threaded sleeve. This ensures the stability of the threaded connection between the threaded section and the threaded sleeve, and also ensures that the operator can smoothly push the insertion strip and the positioning block to slide.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-6A quick-installation rebar sleeve includes a fixed cylinder 1, with threaded sleeves 2 symmetrically welded to both ends of the fixed cylinder 1. Threaded segments 3 are inserted into the interior of each threaded sleeve 2. A rebar body 4 is fixedly connected to the side of the threaded segments 3 that is furthest from each other. The threaded sleeves 2 have internal threads adapted to the threaded segments 3 to achieve quick connection between the threaded segments 3 and the threaded sleeves 2, thus enabling the device to have a quick-installation function. The fixed cylinder 1 has a strip-shaped groove inside, and an insertion strip 5 is inserted into the strip-shaped groove. A positioning block 6 is connected to the side of the insertion strip 5. An annular groove is formed at the end of each threaded segment 3, and a limiting groove adapted to the positioning block 6 is formed on the inner wall of the threaded segment 3 on the side of the annular groove. The strip-shaped groove allows for the movement of the insertion strip 5, facilitating the insertion of the positioning block 6 into or out of the limiting groove. After being pulled out of the limiting groove, the positioning block 6 is embedded in the annular groove. Therefore, through the annular groove opened at the end of the threaded section 3, the smooth rotation of the threaded sleeve 2 is not affected, and it is fitted on the outside of the threaded section 3 to meet the normal threaded connection requirements of the threaded section 3 and the threaded sleeve 2. The side of the insert bar 5 is connected to the connecting rod 7, and the other end of the connecting rod 7 is provided with a pull block 9. The inner side of the pull block 9 is connected to the insert rod 8. The end of the connecting rod 7 is provided with a rectangular groove that matches the insert rod 8. The end of the insert rod 8 is connected to the slider 11. The inside of the connecting rod 7 is provided with a slide that matches the slider 11. The inner side of the pull block 9 is connected to the positioning rod 10. The inside of the fixed cylinder 1 is provided with a slot that matches the positioning rod 10. The inside of the fixed cylinder 1 is provided with a T-shaped groove that matches the connecting rod 7 and the pull block 9. The sliding requirements of the connecting rod 7 and the pull block 9 can be met by opening the T-shaped groove.

[0029] Furthermore, refer to Figure 4 It can be seen that the inner wall of the rectangular groove is connected to a connecting spring 12, and the other end of the connecting spring 12 is connected to the side of the insertion rod 8. During use, the elasticity of the connecting spring 12 itself can effectively ensure the reliability and tightness of the positioning rod 10 when it is inserted into the slot inside the fixed cylinder 1.

[0030] Furthermore, refer to Figure 5 It can be seen that a U-shaped plate 13 is fixedly connected to the side of the fixed cylinder 1, and a fixed shaft 14 is connected to the inner wall of the U-shaped plate 13. A cover plate 15 is movably sleeved on the outer side of the fixed shaft 14. In use, the rotation requirements of the cover plate 15 can be met by the cooperation of the U-shaped plate 13 and the cover plate 15. This makes it convenient for the staff to cover the opening inside the fixed cylinder 1 or to open the opening to pull the moving block 9. The cover plate 15 reduces the amount of impurities entering the interior of the fixed cylinder 1 and the threaded sleeve 2, so as to ensure the normal operation of the internal components.

[0031] Furthermore, refer to Figure 5 It can be seen that torsion springs 16 are symmetrically connected to the side of the cover plate 15, and the other end of the torsion spring 16 is connected to the inner wall of the U-shaped plate 13. Through the elastic characteristics of the torsion spring 16, the tightness of the cover plate 15 when it covers the opening inside the fixed cylinder 1 can be effectively guaranteed, thereby effectively improving the sealing effect of the cover plate 15 on the opening.

[0032] Furthermore, refer to Figure 3 It can be seen that the side of the positioning block 6 is glued with a rubber plate 18, and the rubber plate 18 is set in an inclined shape. The inclined rubber plate 18 can protect the edge of the torsion spring 16 and ensure that it does not collide with the inner wall of the limiting groove when it is embedded in the limiting groove.

[0033] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the outer wall of the threaded sleeve (2) is connected to a rotating plate (17), and the rotating plate (17) is distributed in a ring array on the outer surface of the threaded sleeve (2). During use, the setting of multiple rotating plates makes it easy for the staff to quickly rotate the threaded sleeve (2), thereby satisfying the quick installation function of this device.

[0034] Furthermore, refer to Figure 4 It can be seen that the pull block 9 is set as a rectangular structure, and the inside of the pull block 9 is provided with a slot. During use, the slot makes it easy for the staff to quickly pull the pull block 9 so that it can drive the insertion rod 8 and the slider 11 to move simultaneously, thereby allowing the positioning rod 10 to be pulled out from the slot inside the fixed cylinder 1, thus effectively improving the convenience of using this device.

[0035] Furthermore, refer to Figure 3 and Figure 6 It can be seen that there are two sets of insertion strips 5, and the two sets of insertion strips 5 are symmetrically distributed about the central axis of the fixed cylinder 1. Since there are two sets of insertion strips 5, there are also two sets of components such as positioning block 6, connecting rod 7, insertion rod 8 and pulling block 9, so as to meet the movement requirements of the other set of insertion strips 5. The setting of two sets of positioning blocks 6 can effectively improve the limiting effect of this device on the threaded section 3.

[0036] Furthermore, refer to Figure 3 and Figure 5 It can be seen that the cross-sectional area of ​​the cover plate 15 is larger than the cross-sectional area of ​​the T-slot opening. The inner side of the cover plate 15 is glued with a buffer pad. The cover plate 15 with a larger cross-sectional area can achieve a sealing effect on the internal opening of the fixed cylinder 1. The buffer pad can protect the inner side of the cover plate 15 and prevent it from directly colliding with the outer wall of the fixed cylinder 1 during reset, so as to effectively ensure the service life of the cover plate 15.

[0037] Furthermore, refer to Figure 4 It can be seen that the side of the pull block 9 is connected to two sets of positioning rods 10, and the two sets of positioning rods 10 are symmetrically distributed about the central axis of the pull block 9. Since the pull block 9 is provided with two sets, in order to meet the limiting requirements of the pull block 9 and the connecting rod 7, the inside of the fixed cylinder 1 is provided with four sets of slots that are compatible with the positioning rods 10. Through the two sets of positioning rods 10 provided on the inner side of the pull block 9, the limiting effect of the pull block 9 on the connecting rod 7 can be further improved.

[0038] Working principle: When using this utility model, the worker can first bring the steel bar bodies 4 that need to be assembled close to each other, and then the worker can rotate the threaded sleeve 2 to put it on the outside of the threaded section 3 provided at the end of the steel bar body 4. Then the worker can completely insert the threaded section 3 connected to the end of another set of steel bar bodies 4 into the inside of the other set of threaded sleeves 2. At this time, the assembly of the steel bars can be completed through the two sets of threaded sleeves 2 provided between the two sets of steel bar bodies 4.

[0039] Then, the operator can first rotate the cover plate 15 so that it can slide along the outer wall of the fixed shaft 14 under force, thereby opening the T-shaped groove opening inside the fixed cylinder 1. Then, the operator can pull the pulling block 9 outward in sequence to pull out the positioning rod 10 connected to its inner side from the slot opened inside the fixed cylinder 1, thereby releasing the limitation on the connecting rod 7 and the insertion strip 5. Then, the operator can slide the pulling block 9 laterally. With the cooperation of the slider 11 and the slide rail opened inside the connecting rod 7, it can drive the insertion rod 8 / connecting rod 7 / insertion strip 5 and positioning block 6 to move simultaneously, and make the positioning block 6 engage in the corresponding limiting groove opened at the end of the threaded section 3. At this time, the positioning rod 10 connected to the inner side of the pulling block 9 can be aligned with the position of another set of slots. Therefore, the operator only needs to stop pulling the pulling block 9 outward to make the positioning rod 10 connected to the inner side of the pulling block 9 engage in another set of slots, thereby realizing the limitation work of the pulling block 9 and the connecting rod 7.

[0040] After both sets of positioning blocks 6 are inserted into the limiting grooves opened at the ends of the threaded section 3, the operator can stop rotating the cover plate 15, so that it can be reset by the force of the torsion spring 16, and cover and seal the opening inside the fixed cylinder 1 again. When the threaded sleeve 2 and the threaded section 3 are subjected to vibration during the connection process, the positioning blocks 6 inserted in the ends of the threaded section 3 can realize the transverse fibers of the threaded section 3, thereby effectively preventing the threaded section 3 and the threaded sleeve 2 from slipping during the connection. The above is the complete working principle of this utility model.

[0041] In this utility model, the installation, connection or setting methods of all the components mentioned above are common mechanical methods, and the specific structure, model and coefficient index of all the components are their own technologies.
