Description

Technical Field

[0001] The utility model belongs to the technical field of steel bar connection, and particularly relates to a split straight thread steel bar connection sleeve structure. Background Art

[0002] The split straight thread rebar connection sleeve primarily consists of two symmetrical semi-cylindrical sleeves with tapered outer surfaces and two locking sleeves with tapered inner surfaces. The outer diameter of the semi-cylindrical sleeves tapers gradually from the center toward the ends, allowing them to better interlock with the rebar threads during connection. The locking sleeves securely lock the two sleeve halves together, ensuring a secure connection.

[0003] To connect, first place the two halves of the outer conical sleeve at the joint of the two straight-threaded rebars to be connected, ensuring that the outer conical surface of the sleeve tightly engages the threads of the rebars. Next, tighten the two inner conical locking sleeves from each end. The locking sleeves' taper angle is smaller than the self-locking angle, preventing them from falling off after tightening. In this way, the two rebars are securely connected via the split sleeve.

[0004] A potential problem with split-type straight-thread rebar connectors after connection is that their ends often lack a complete and effective sealing structure. This flaw is particularly prominent in certain operating environments, especially when they are exposed to humid, wet, or corrosive environments. Without the necessary sealing protection, external moisture and humidity can easily penetrate the interior of the connector, coming into direct contact with the rebar and connected components.

[0005] Over time, this constant exposure to moisture inevitably leads to rust and corrosion of internal metal components. Rust not only degrades the mechanical properties of the rebar and connecting sleeves, significantly compromising their load-bearing capacity, but can also cause loosening and failure of the connections, posing a serious threat to the stability and safety of the entire structure. In critical engineering projects such as bridges, high-rise buildings, and large-scale infrastructure, the corrosion of split straight thread rebar connecting sleeves is a serious concern. Utility Model Content

[0006] The purpose of this utility model is to provide a split straight-threaded rebar connection sleeve structure that addresses the problem of external moisture and humidity easily penetrating the interior of the connection sleeve due to the lack of necessary sealing protection, thereby coming into direct contact with the internal rebar and connection components. Over time, this continued moisture contact inevitably leads to rust and corrosion of the internal metal components. Rust not only degrades the mechanical properties of the rebar and connection sleeve, significantly reducing their load-bearing capacity, but can also cause the connection to loosen and fail, posing a serious threat to the stability and safety of the entire structure.

[0007] To achieve the above object, the present invention provides the following technical solution: a split straight threaded steel bar connecting sleeve structure, comprising a straight threaded steel bar, two straight threaded steel bars are connected together by a connecting sleeve, and a set of end sleeves are respectively bonded to both ends of the connecting sleeve;

[0008] Two clips are symmetrically mounted on the outer wall of the end sleeve.

[0009] In order to stir the alcohol ester raw materials, as a preferred structure of a split straight threaded steel bar connection sleeve of the utility model, the end sleeve is made of deformable hard rubber material, the side of the end sleeve is a C-shaped structure, and each group of end sleeves consists of two. A notch is provided on the outer wall of each end sleeve. An end plate is fixedly connected to the outer wall at both ends of the clip opening, and a bolt is threaded through one side of the end plate. The size of the clip is adapted to the size of the notch, and a clip is respectively sleeved on the two end sleeves of each group, and the two clips on the end sleeves of this group are locked on the end sleeves through the corresponding end plates and bolts.

[0010] In order to flush the funnel-shaped filter screen, as a preferred structure of a split straight threaded steel bar connection sleeve of the utility model, a circle of sealing ring is embedded in the inner wall of the end sleeve, and the inner wall of the sealing ring is tightened and wrapped around the outer wall of the straight threaded steel bar.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] When docking, the two straight threaded steel bars are respectively passed through a set of end sleeves and docked with the inside of the connecting sleeve. After the docking is completed, the two clips are put on the outer wall of the end sleeve, and then the two clips are tightened. As the two clips are tightened, the two clips will squeeze the end sleeves inward. When the end sleeves are squeezed, the sealing rings will be tightened and squeezed on the outer wall of the corresponding straight threaded steel bar. In this way, a good sealing structure can be formed through this structure at the connection end of the end sleeve and the straight threaded steel bar. Therefore, water stains will not flow to the connection part of the straight threaded steel bar and the connecting sleeve during use, so that the connection part of the straight threaded steel bar and the connecting sleeve has a good function of preventing water stains and rust.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4 The utility model provides the following technical solutions: a split straight threaded steel bar connecting sleeve structure, comprising a straight threaded steel bar 1, two straight threaded steel bars 1 are connected together by a connecting sleeve 2, and a group of end sleeves 3 are respectively bonded to both ends of the connecting sleeve 2;

[0021] Two clips 4 are symmetrically mounted on the outer wall of the end sleeve 3 .

[0022] Preferably: the end sleeve 3 is made of deformable hard rubber material, the side of the end sleeve 3 is a C-shaped structure, and each group of end sleeves 3 consists of two. A notch 301 is provided on the outer wall of each end sleeve 3. An end plate 401 is fixedly connected to the outer wall of the two ends of the opening of the clip 4, and a bolt 402 is threaded through one side of the end plate 401. The size of the clip 4 is adapted to the size of the notch 301, and each group of two end sleeves 3 is respectively sleeved with a clip 4, and the two clips 4 on the group of end sleeves 3 are locked on the end sleeve 3 by the corresponding end plate 401 and the bolt 402. A circle of sealing ring 302 is embedded in the inner wall of the end sleeve 3, and the inner wall of the sealing ring 302 is tightened and wrapped around the outer wall of the straight threaded steel bar 1.

[0023] In practical use, when connecting the straight threaded steel bars 1, first, two prepared straight threaded steel bars 1 need to be passed through a set of pre-configured end sleeves 3 and the inner space of the connecting sleeve 2 to ensure that they can be smoothly and tightly connected together. After the connection is successfully completed, the next step is to fit the two clips 4 into the notches 301 on the outer wall of the end sleeve 3;

[0024] Subsequently, the bolts 402 on the two clips 4 are tightened, so that the corresponding two end plates 401 are brought closer to each other, thereby tightening the two clips 4. As the clips 4 are gradually tightened, they will exert an inward force on the end sleeve 3, which in turn causes the end sleeve 3 to be squeezed into its internal space. During this process, the sealing ring 302 equipped inside the end sleeve 3 will also be subjected to a corresponding squeezing effect, tightly fitting and squeezing on the outer wall of the corresponding straight threaded steel bar 1. This mechanism is designed to create an efficient sealing effect through physical pressure, ensuring that the connection end of the end sleeve 3 and the straight threaded steel bar 1 can form a strong and tight sealing structure.

[0025] This design not only greatly enhances the stability and durability of the connection, but more importantly, it effectively prevents water or other liquids from the external environment from penetrating the connection between the straight threaded steel bar 1 and the connecting sleeve 2. This ensures that the connection between the straight threaded steel bar 1 and the connecting sleeve 2 will not rust due to water erosion, even when used in humid or water-rich environments. This significantly extends the service life of the entire structure and improves its overall safety and reliability.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
