Description

Technical Field

[0001] The utility model relates to the technical field of steel bar connectors, in particular to a steel bar connecting sleeve with a split end at one end and a movable end at the other end. Background Art

[0002] Traditional steel bar connection methods are usually relatively cumbersome to operate. This type of connection device generally relies on a combination of a sleeve and two locking sleeves to achieve the connection function. For example, a typical steel bar connection device disclosed in patent application number 201922288914.3 requires the operator to screw the two locking sleeves onto the sleeve separately before connecting the steel bars. This process is not only time-consuming and labor-intensive, but also greatly limits the flexibility and convenience of the connection.

[0003] In view of the shortcomings of traditional connection methods in terms of operational convenience, flexibility and overall connection efficiency, we urgently need a more advanced and efficient steel bar connection solution. Therefore, we proposed an innovative steel bar connection sleeve with one end split and the other end movable. Utility Model Content

[0004] A technical problem to be solved by the present application is to solve the problem that the traditional steel bar connection method is insufficient in terms of operational convenience, flexibility and overall connection efficiency.

[0005] In order to solve the above technical problems, the embodiment of the present application provides a rebar connection sleeve with one end split and the other end movable, comprising a sleeve, wherein the opening diameter of one end of the sleeve is the same as the inner diameter of the sleeve, and the opening diameter of the other end of the sleeve is smaller than the inner diameter of the sleeve;

[0006] Also included are:

[0007] A straight-insert locking sleeve, which is directly inserted from the end of the sleeve opening with a larger diameter and is engaged with the end of the sleeve opening with a smaller diameter;

[0008] The threaded locking sleeve has an outer diameter that is the same as the inner diameter of the sleeve, and matching thread grooves are respectively provided on the outer periphery of the threaded locking sleeve and the inner wall of the sleeve, and the straight-insert locking sleeve and the threaded locking sleeve are also provided with thread grooves.

[0009] In some embodiments, the straight-insert locking sleeve is an integrally formed circular ring, the outer diameter of the circular ring is the same as the inner diameter of the end with the smaller diameter of the sleeve opening, and an annular protrusion is arranged on the outer side of one end.

[0010] In some embodiments, grooves are provided on opposite sides of the annular protrusion and the inner wall of the sleeve end, and the grooves on the annular protrusion and the inner wall of the sleeve end are offset from each other.

[0011] In some embodiments, one end of the thread locking sleeve is polygonal.

[0012] In some embodiments, the sleeve is a forged polygonal shape.

[0013] The utility model has at least the following beneficial effects:

[0014] 1. The design of the connecting sleeve greatly simplifies the operation process of steel bar connection. The straight-insert locking sleeve can be directly inserted from the end with a larger opening diameter of the sleeve and easily engaged with the end with a smaller opening diameter. There is no need to screw two locking sleeves separately as in the traditional way, thereby saving time and manpower and ensuring the efficient connection and use of steel bars.

[0015] 2. The design of split end and movable end makes the connecting sleeve more flexible when connecting steel bars. The combination of straight-insert locking sleeve and threaded locking sleeve not only ensures the firmness of the connection, but also allows quick disassembly and adjustment when necessary, meeting the needs of different construction scenarios.

[0016] 3. The polygonal design of the sleeve not only increases its aesthetics, but also improves the reliability and durability of the connection. At the same time, one end of the polygonal threaded locking sleeve is convenient for tightening with tools such as wrenches, further improving the convenience and efficiency of the connection.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1: The utility model provides a technical solution: See the attached Figure 1 As shown, a rebar connection sleeve with a split end and a movable end includes a sleeve 1, a straight-insertion locking sleeve 2 and a threaded locking sleeve 3;

[0028] in:

[0029] The diameter of the opening at one end of the sleeve 1 is the same as the inner diameter of the sleeve 1, and the diameter of the opening at the other end of the sleeve 1 is smaller than the inner diameter of the sleeve 1. Figure 2-Figure 3 As shown;

[0030] The straight-insertion locking sleeve 2 has an outer diameter smaller than the inner diameter of the opening of the sleeve 1 at the end with a larger opening diameter. Figure 2-Figure 3 As shown, when the end of the sleeve 1 with a larger opening diameter is not blocked, the straight-insertion locking sleeve 2 can be directly inserted from the end of the sleeve 1 with a larger opening diameter and snapped into the end of the sleeve 1 with a smaller opening diameter, thus abandoning the traditional threaded connection method and making the assembly and disassembly of the straight-insertion locking sleeve 2 more flexible and convenient;

[0031] The threaded locking sleeve 3 has an outer diameter that is the same as the inner diameter of the sleeve 1, and matching thread grooves are provided on the outer periphery of the threaded locking sleeve 3 and the inner wall of the sleeve 1, respectively. This design enables the threaded locking sleeve 3 to still be connected to the sleeve 1 by means of threads, thereby ensuring the stability of the overall connection.

[0032] It should be noted that if Figure 3 As shown, after the threaded locking sleeve 3 is installed in the sleeve 1, the end of the threaded locking sleeve 3 located in the sleeve 1 is in close contact with the straight-insertion locking sleeve 2, which can ensure the stability of the straight-insertion locking sleeve 2 in connecting the steel bars and effectively prevent its shaking from affecting the stability and safety of the steel bar docking;

[0033] In addition, both the straight-insert locking sleeve 2 and the threaded locking sleeve 3 are provided with thread grooves, but it should be noted that Figure 2As shown, the inner thread groove of the threaded locking sleeve 3 extends from one end to the middle position inside the threaded locking sleeve 3. Such a design allows the steel bars loaded from the straight-insertion locking sleeve 2 to be inserted into the threaded locking sleeve 3 when the steel bars are installed. At this time, it is necessary to reasonably adjust the inner diameter of the threaded locking sleeve 3, so as to ensure that the steel bars inserted into the straight-insertion locking sleeve 2 can obtain sufficient force points, that is, to ensure sufficient insertion depth, maintain effective fixed docking, and after the thread groove is processed at the end of the steel bar, the steel bar can be directly connected to two different locking sleeves.

[0034] It should be emphasized that Figure 2 As shown, the straight-insert locking sleeve 2 is specifically an integrally formed circular ring, the outer diameter of which is the same as the inner diameter of the end of the sleeve 1 with a smaller opening diameter, and an annular protrusion 4 is arranged on the outer side of one end, and the outer diameter of the annular protrusion 4 is larger than the inner diameter of the end of the sleeve 1 with a smaller opening, so that after the straight-insert locking sleeve 2 is directly inserted into the sleeve 1, the small diameter of the end of the sleeve 1 can be used to restrict the straight-insert locking sleeve 2 in the sleeve 1, and cooperate with the threaded locking sleeve 3 for stable installation.

[0035] Example 2: Please refer to Figure 4 As shown, on the basis of Example 1, the present application provides another technical solution of the straight-insert locking sleeve 2: a groove 5 is provided on the opposite side of the annular protrusion 4 and the inner wall of the end of the sleeve 1, and the annular protrusion 4 and the groove 5 on the inner wall of the end of the sleeve 1 are staggered with each other. Compared with the design of Example 1, such a design enables the straight-insert locking sleeve 2 to provide more stable docking and installation capabilities through stable engagement after being inserted into the sleeve 1, but the defect is that the processing of the straight-insert locking sleeve 2 is slightly more complicated than the straight-insert locking sleeve 2 of Example 1.

[0036] Example 3: Please refer to the attached Figure 5 As shown, the present application provides another technical solution based on Example 1 and Example 2: one end of the threaded locking sleeve 3 is a polygon. Compared with Examples 1-2, such a design can make the disassembly and assembly of the threaded locking sleeve 3 more convenient, but the disadvantage is that the processing is relatively troublesome.

[0037] Example 4: Please refer to the attached Figure 6 As shown, on the basis of embodiments 1-3, the sleeve 1 can be a forged polygonal shape, and the polygonal structure can be used to effectively increase the bearing capacity of the sleeve 1.

[0038] Example 5: Please refer to the attached Figure 7 As shown, on the basis of embodiments 1-4, a locking nut 6 is arranged on the outside of the threaded locking sleeve 3, and the outer diameter of the locking nut 6 is larger than the outer diameter of the sleeve 1 so as to abut against the outer side of the sleeve 1 for locking.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0040] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
