Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a connecting sleeve structure for deformed steel bars. Background Art

[0002] During the construction process on the construction site, deformed steel bars are often used, and the arrangement of deformed steel bars is often involved. After the arrangement of deformed steel bars is completed, there are often situations where two independent coaxial deformed steel bars need to be fixed (that is, two independent deformed steel bars are respectively fixed to the building, and the two deformed steel bars are coaxial and have the same thickness or different thicknesses). In the related art, when facing two coaxial and fixed deformed steel bars, the general method is to use welding for fixing.

[0003] The method of fixing by welding not only requires a welding machine and welding rods, but also needs to ensure the firmness of welding, which is time-consuming and laborious during the implementation process. The method of connecting through a threaded sleeve is relatively simple. However, when connecting with a threaded sleeve, one end of the threaded sleeve needs to be rotatably connected to one end of the deformed steel bar first. At this time, only by rotating the threaded sleeve can the deformed steel bar be connected to the threaded sleeve, and then the other end of the threaded sleeve is rotatably connected to another deformed steel bar. When connecting the second deformed steel bar, the deformed steel bar needs to be rotated to thread one end of the other deformed steel bar onto the other end of the threaded sleeve. Since the deformed steel bar is long and heavy, it is relatively laborious to rotate. Therefore, the present application proposes a connecting sleeve structure for deformed steel bars. Summary of the Invention

[0004] The purpose of the utility model is to propose a connecting sleeve structure for deformed steel bars in view of the problem in the background art that since the deformed steel bar is long and heavy, it is relatively laborious to rotate.

[0005] The technical solution of the utility model: A connecting sleeve structure for deformed steel bars, including a first threaded sleeve and a second threaded sleeve. One end of the first threaded sleeve is provided with a first circular groove, a limiting circular groove is opened in the first circular groove, an arc-shaped groove is opened on the inner wall of the first circular groove along the length direction of the first circular groove, and the arc-shaped groove communicates with the limiting circular groove. A stud is threadedly connected to the first threaded sleeve, and a plurality of fixing columns evenly distributed in a ring are fixedly connected to the first threaded sleeve. The arc-shaped groove and the stud are located on the side of the limiting circular groove away from the fixing columns, and one end of the stud extends into the first circular groove. A connecting column for inserting into the first circular groove is fixedly connected to the second threaded sleeve, a limiting block is fixedly connected to one end of the connecting column, and the limiting block is rotatably installed in the arc-shaped groove. A plurality of second circular grooves for inserting are opened at one end of the second threaded sleeve close to the first threaded sleeve.

[0006] Optionally, both ends of the limiting block are arc-shaped surfaces, the limiting block is fitted on the arc-shaped groove, and the limiting block is rotatably connected to the limiting circular groove.

[0007] Optionally, threaded connection holes are provided on the limit block, and the threaded connection holes are in threaded connection with the stud.

[0008] Optionally, threaded holes are provided on the first threaded sleeve, and a threaded steel main body is in threaded connection with the threaded holes. A first housing for lubricating the threaded steel main body is provided on the first threaded sleeve, and the internal space of the first housing is connected to the threaded holes on the first threaded sleeve.

[0009] Optionally, a first sealing plug is in threaded connection with the first housing.

[0010] Optionally, threaded holes are provided on the second threaded sleeve, and a threaded steel main body is in threaded connection with the threaded holes. A second housing for lubricating the threaded steel main body is provided on the second threaded sleeve, and the internal space of the second housing is connected to the threaded holes on the second threaded sleeve.

[0011] Optionally, a second sealing plug is in threaded connection with the second housing.

[0012] In summary, the present application includes at least one of the following beneficial technical effects:

[0013] The threaded sleeve is split into a first threaded sleeve and a second threaded sleeve. By rotating the first threaded sleeve and the second threaded sleeve to tighten them with the threaded steel, it is not necessary to rotate the relatively long threaded steel, making the connection between the sleeve and the threaded steel more labor-saving.

[0014] Through the detachable connection between the first threaded sleeve and the second threaded sleeve, the connection of the split threaded sleeves is realized, and the operation is convenient. Thus, the connection of two long-distance threaded steels is indirectly realized, improving the convenience of the connection between the threaded steel and the threaded sleeve.

[0027] Embodiment 1

[0028] As Figure 1-2 shown, the threaded steel connection sleeve structure proposed by the present utility model includes a first threaded sleeve 1 and a second threaded sleeve 2. The first threaded sleeve 1 is formed by welding two cylindrical bodies with internal threads. One end of the first threaded sleeve 1 is provided with a first circular groove 101. A limiting circular groove 102 is provided in the first circular groove 101. An arc-shaped groove 103 is provided on the inner wall of the first circular groove 101 along the length direction of the first circular groove 101. The arc-shaped groove 103 communicates with the limiting circular groove 102. A stud 104 is threadedly connected to the first threaded sleeve 1. A plurality of fixing columns 105 evenly distributed in a ring are fixedly connected to the first threaded sleeve 1. The arc-shaped groove 103 and the stud 104 are located on the side of the limiting circular groove 102 away from the fixing columns 105, and one end of the stud 104 extends into the first circular groove 101. A connecting column 201 for inserting into the first circular groove 101 is fixedly connected to the second threaded sleeve 2. A limiting block 202 is fixedly connected to one end of the connecting column 201. The limiting block 202 is rotatably installed in the arc-shaped groove 103, so that the second threaded sleeve 2 can be fixed. A plurality of second circular grooves 203 for inserting the fixing columns 105 are provided at one end of the second threaded sleeve 2 close to the connecting column 201. The insertion of the fixing columns 105 into the second circular grooves 203 is used to increase the overall strength of the threaded sleeve. Since the length and mass of the threaded steel are much larger than those of the threaded sleeve, it is very laborious to connect by screwing the threaded steel. In this solution, the threaded sleeve is split into two rotatable connection ends, namely the first threaded sleeve 1 and the second threaded sleeve 2. After connecting the first threaded steel to the first threaded sleeve 1 by rotating the first threaded sleeve 1, and then by rotating the second threaded sleeve 2, another threaded steel can be tightened onto the threaded hole on the second threaded sleeve 2. Because the mass and length of the second threaded sleeve 2 are much smaller than those of the threaded steel, connecting by screwing the second threaded sleeve 2 can achieve the effect of labor-saving installation.

[0029] As Figure 3As shown, both ends of the limit block 202 are arc-shaped. The limit block 202 is fitted on the arc-shaped groove 103 and is rotatably connected to the limit circular groove 102. When the limit block 202 is in the arc-shaped groove 103, the first threaded sleeve 1 and the second threaded sleeve 2 cannot rotate relative to each other. When the limit block 202 is in the limit circular groove 102, the first threaded sleeve 1 and the second threaded sleeve 2 can rotate relative to each other.

[0030] As Figure 3-4 shown, a threaded connection hole 2020 is provided on the limit block 202. The threaded connection hole 2020 is threadedly connected to the stud 104. By connecting the stud 104 to the threaded connection hole 2020, the limit block 202 can be fixed on the arc-shaped groove 103.

[0031] As Figure 1-2 shown, a threaded hole is provided on the first threaded sleeve 1. A threaded steel body 3 is threadedly connected to the threaded hole. A first housing 106 for lubricating the threaded steel body 3 is provided on the first threaded sleeve 1. The internal space of the first housing 106 is connected to the threaded hole on the first threaded sleeve 1. A first sealing plug 107 is threadedly connected to the first housing 106. By rotating the first threaded sleeve 1, the threaded steel body 3 is connected. Then, some lubricating liquid is injected into the first housing 106. This can not only lubricate the connection between the threaded steel body 3 and the first threaded sleeve 1, but also play an anti-rust role subsequently.

[0032] As Figure 3-4 shown, a threaded hole is provided on the second threaded sleeve 2. A threaded steel body 3 is threadedly connected to the threaded hole. A second housing 204 for lubricating the threaded steel body 3 is provided on the second threaded sleeve 2. The internal space of the second housing 204 is connected to the threaded hole on the second threaded sleeve 2. A second sealing plug 205 is threadedly connected to the second housing 204. By rotating the second threaded sleeve 2, the threaded steel body 3 is connected. Then, some lubricating liquid is injected into the second housing 204. This can not only lubricate the connection between the threaded steel body 3 and the second threaded sleeve 2, but also play an anti-rust role subsequently.

[0033] The above specific embodiments are merely several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
