[0002] During the construction process, the impact of steel bar engineering on structural safety is particularly important. Among them, large diameter steel bars are mostly connected mechanically. After the steel bar threading is completed, the protection of the steel bar wire head is particularly important. In order to effectively prevent the steel bar wire head from rusting, colliding and other series of situations, on-site construction requires the use of steel bar wire head protection caps for protection.
[0003] The steel wire head protection caps in the prior art are all of threaded design, and the steel wire heads are wrapped and protected by screwing in matching threads. However, this type of steel wire head protection cap requires the operator to rotate each steel wire head in little by little, which leads to slow construction speed and very low efficiency. During the mechanical connection process, it is necessary to rotate it out little by little, which requires a high sense of responsibility from the workers, especially when the number of steel wire heads is large, which greatly consumes labor costs. Due to this complicated construction process, operators often fail to protect the wire heads or forcibly remove them, causing steel corrosion, affecting the quality and safety of the structure and the construction progress, and reducing the turnover rate of the wire head protection cap. Therefore, it is necessary to provide a clamp-type steel wire head protection cap that can solve the problem of inefficient and inconvenient thread disassembly and assembly of the steel wire head protection cap in the prior art.

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0021] Please see attached Figure 1 To Attachment Figure 3 A clamp-type steel wire head protective cap comprises a protective cap body 1, a clamp handle 2, a sealing clamping assembly and an elastic opening and closing piece 4; one end of a pair of clamp handles 2 is symmetrically arranged in the protective cap body 1 and correspondingly connected to a pair of sealing clamping assemblies, and the other ends of the pair of clamp handles 2 extend to both sides of the outside of the protective cap body 1 respectively; a pair of sealing clamping assemblies are spliced in the protective cap body 1 to form a circular ring structure, so that when the protective cap body 1 is sleeved on the end of the steel wire head, the inner wall of the circular ring structure can be sealed and clamped on the steel wire head; a plurality of groups of elastic opening and closing pieces 4 are respectively embedded in the protective cap body 1 at intervals, and a plurality of groups of elastic opening and closing pieces 4 are connected between the protective cap body 1 and the outer wall of the circular ring structure.
[0022] Preferably, the protective cap body 1 can be a conventional steel wire head protective cap, and the clamp handle 2 can be made of hard materials such as plastic. When the pair of clamp handles 2 are pulled toward the outside of the protective cap body 1, the pair of sealing clamping components are separated, which is convenient for sleeve-fitting the protective cap body 1 onto the steel wire head. At this time, the elastic opening and closing member 4 is compressed and stored. When the pair of clamp handles 2 are released, the pair of sealing clamping components are brought closer to each other and spliced to form a circular ring structure under the elastic force of the elastic opening and closing member 4, thereby clamping on the steel wire head to prevent the protective cap body 1 from falling off, and the circular ring structure formed by the pair of sealing clamping components has good sealing performance, which effectively prevents water from penetrating into the gap between the protective cap body 1 and the steel wire head, causing the steel wire head to rust and corrode.
[0023] Please see attached Figure 1 To Attachment Figure 3The sealing clamping assembly includes a semicircular ring-shaped steel wire head clamping piece 301 and a steel wire head sealing piece 302. The steel wire head sealing piece 302 is embedded in the middle part of the steel wire head clamping piece 301 along the height direction; the outer wall of the steel wire head sealing piece 302 is connected to one end of the clamp handle 2, and the inner wall of the steel wire head sealing piece 302 is tightly attached to the surface of the steel wire head; the inner wall of the steel wire head clamping piece 301 is tightly attached to the surface of the steel wire head, and the elastic opening and closing piece 4 is connected between the outer wall of the steel wire head clamping piece 301 and the protective cap main body 1.
[0024] Preferably, the steel wire head clamping piece 301 can be made of rubber with low elasticity and small deformation, so as to ensure that the annular structure formed by a pair of steel wire head clamping pieces 301 can have good clamping force on the steel wire head and prevent the protective cap body 1 from falling off. The steel wire head sealing piece 302 can be made of soft rubber with high elasticity and good deformation performance, so as to ensure the clamping and sealing performance between the steel wire head sealing piece 302 and the steel wire head.
[0025] The inner diameter, outer diameter, height and other dimensions of the steel wire clamp 301 and the steel wire seal 302 can be made according to the specifications of the steel wire to ensure that the annular structure formed by the steel wire clamp 301 and the steel wire seal 302 can surround and clamp on the surface of the steel wire, and the deformation performance of the rubber can be used to ensure the clamping and sealing effect. The rubber specifications of the steel wire clamp 301 and the steel wire seal 302 can be adaptively selected according to actual use requirements, and the steel wire clamp 301 and the steel wire seal 302 can be integrally formed to ensure that the clamp handle 2 drives the overall movement of the sealing clamp assembly.
[0026] Please see attached Figure 1 To Attachment Figure 3 The inner wall of the steel wire head sealing member 302 protrudes from the inner wall of the steel wire head clamping member 301 .
[0027] Preferably, the inner diameter of the steel wire head clamp 301 is slightly smaller than the diameter of the steel wire head to ensure the clamping effectiveness, and the inner diameter of the steel wire head seal 302 is slightly smaller than the inner diameter of the steel wire head clamp 301, so that the steel wire head seal 302 protrudes from the inner wall of the steel wire head clamp 301.
[0028] When a pair of steel wire head clamping members 301 are clamped on the steel wire head, a small deformation is generated between the steel wire head sealing member 302 and the steel wire head due to the extrusion, and the deformation of the steel wire head sealing member 302 is used to ensure the clamping and sealing performance of the steel wire head.
[0029] Preferably, the inner wall of the steel wire clamping member 301 protrudes 1.5-3 mm from the inner wall of the steel wire seal 302. The size of the steel wire seal 302 can also be adaptively adjusted according to actual use requirements.
[0030] Please see attached Figure 1 and attached Figure 3 A circular clamp installation cavity 101 is formed on the protective cap body 1 along the circumferential direction, and a plurality of groups of elastic opening and closing parts 4 are respectively and spacedly embedded between the inner wall of the clamp installation cavity 101 and the outer wall of the steel wire head clamping part 301. One end of the clamp handle 2 is arranged through the clamp installation cavity 101, so that the sealing clamping assembly can be embedded in the clamp installation cavity 101.
[0031] Preferably, the clamp installation cavity 101 is protrudingly arranged near the open end of the protective cap body 1, which is convenient for the installation of a pair of clamp handles 2 and a plurality of groups of elastic opening and closing parts 4. The depth of the clamp installation cavity 101 is greater than the thickness of the sealing clamping assembly, which is convenient for the sealing clamping assembly to be embedded in the clamp installation cavity 101 under the pulling of the clamp handle 2, thereby facilitating the protective cap body 1 to be sleeved onto the steel wire head.
[0032] Please see attached Figure 3 Each group of the elastic opening and closing parts 4 includes multiple springs, and the multiple springs are arranged along the radial direction of the steel wire head clamping part 301.
[0033] Preferably, each group of elastic opening and closing parts 4 may include four springs, which are symmetrically arranged about the clamp handle 2 and are evenly stressed; the elastic coefficient of the spring can be adaptively selected according to actual usage requirements to ensure that the elastic force of the elastic opening and closing parts 4 can be used to press the sealing clamping assembly onto the steel wire head.
[0034] Several groups of elastic opening and closing parts 4 are arranged at equal intervals along the circumference of the clamp installation cavity 101. Since the deformation of the steel wire head clamping part 301 is very small and the hardness is high, multiple groups of elastic opening and closing parts 4 can be compressed at the same time when the clamp handle 2 is pulled to ensure the opening of a pair of steel wire head clamping parts 301. When the clamp handle 2 is released, the elastic force of the multiple groups of elastic opening and closing parts 4 can be used to close the pair of steel wire head clamping parts 301 and clamp the steel wire head.
[0035] Please see attached Figure 1 To Attachment Figure 3 The clamp handle 2 is sleeved with an anti-drop buckle 5, which is pressed tightly against the outer wall of the clamp installation cavity 101.
[0036] Preferably, an external thread can be set on the clamp handle 2, and an internal thread matching the external thread of the clamp handle 2 can be set on the inner wall of the anti-drop buckle 5, so that the anti-drop buckle 5 is pressed against the outer wall of the clamp mounting cavity 101 when the thread is screwed, preventing the clamp handle 2 from loosening.
[0037] Please see attached Figure 1 The protective cap body 1 and the fixture installation cavity 101 are an integrated structure.
[0038] The protective cap body 1 and the clamp installation cavity 101 are integrally formed, and have high structural strength and are not easily damaged, thereby ensuring the pulling stability of a pair of clamp handles 2 .
[0039] Please see attached Figure 1 To Attachment Figure 3 , the method of using the utility model is:
[0040] The construction worker holds the pair of clamp handles 2 with both hands and pulls the pair of clamp handles 2 outwards, and one end of the pair of clamp handles 2 located in the clamp installation cavity 101 drives the steel wire head seal 302 to move outwards synchronously, thereby pulling the sealing clamp assembly to be embedded in the clamp installation cavity 101. At this time, the pair of sealing clamp assemblies are separated, and the elastic opening and closing member 4 is compressed and stored.
[0041] The protective cap body 1 is sleeved onto the end of the steel wire head, and the pair of clamp handles 2 are released. Under the elastic force of the elastic opening and closing member 4, the pair of sealing clamping components are pushed out of the clamp installation cavity 101 and pressed against the steel wire head. The pair of sealing clamping components are spliced to form a circular ring structure, and the steel wire head is clamped by the steel wire head clamping member 301. The deformation of the steel wire head seal 302 ensures the clamping and sealing performance of the steel wire head seal 302 on the steel wire head.
[0042] During disassembly, it is only necessary to pull the pair of clamp handles 2 outwards to separate the pair of sealing clamping components and embed them into the clamp installation cavity 101, thereby separating the pair of sealing clamping components from the steel wire head and removing the protective cap body 1.
[0043] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
