Description

Technical Field

[0001] The utility model relates to the field of anchor clamp pieces, in particular to a self - absorbing anchor clamp piece. Background Art

[0002] An anchor is a tool used for anchoring prestressed steel strands, steel wires, and reinforcing bars of a drawing instrument for reinforcing bars. An anchor usually consists of parts such as an anchor ring, clamp pieces, and an anchor backing plate. Its clamp pieces can anchor wire rods to transfer tension, ensure the stability of prestress or tension, prevent the wire rods from sliding, and improve the reliability and durability of the structure. Currently, the anchor clamp pieces used in the market usually consist of 2 - 3 pieces. During the assembly of the anchor, the clamp pieces are prone to falling off and detaching after the force is removed. Especially during high - altitude installation, they are likely to fall off, be missing, and pose a safety hazard of falling and hitting, resulting in the anchor being unable to play an anchoring role in a short time, affecting the stress performance and anchoring effect. It cannot meet the construction requirements and economic benefits, so this phenomenon is solved through technical solution improvement.

[0003] Therefore, there is an urgent need for a self - absorbing anchor clamp piece that can maintain an adsorption connection during installation to avoid falling off. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a self - absorbing anchor clamp piece to solve the problem that there is no connection between existing clamp piece monomers and they are prone to falling off during installation.

[0005] To solve the above - mentioned technical problems, the utility model adopts the following technical solutions:

[0006] A self - absorbing anchor clamp piece of the utility model includes at least two clamp piece monomers. All the clamp piece monomers can be assembled into a clamp piece integral body. The external contour shape of the clamp piece integral body is a frustum - of - cone shape, and there is a through - hole at the central axis of the clamp piece integral body; each clamp piece monomer includes a fitting surface, and the fitting surfaces of adjacent two clamp piece monomers can be mutually fitted; a plurality of accommodating grooves are opened on the fitting surface, an activity plate is hinged in the accommodating groove, and the activity plate has magnetism; the activity plate has two states of flipping into and out of the accommodating groove. When the activity plate flips into the accommodating groove, the outer surface of the activity plate is flush with the fitting surface where it is located; the activity plates on the two mutually - fitted fitting surfaces face two opposite directions respectively, and the opposite sides of the activity plates on the two mutually - fitted fitting surfaces are N - pole and S - pole respectively.

[0007] In some embodiments, the activity plate is hinged in the accommodating groove through a rotating shaft.

[0008] In some embodiments, the rotating shaft is arranged on one side of the activity plate.

[0009] In some embodiments, the contour of the accommodating groove is larger than the contour of the activity plate, and the two contour shapes are the same.

[0010] In some embodiments, an isolation layer is inlaid in the accommodation groove.

[0011] In some embodiments, a plurality of accommodation grooves on the same clip monomer are arranged in sequence from top to bottom, and the sizes of the accommodation grooves become smaller from top to bottom.

[0012] In some embodiments, threads are formed on the inner wall of the through hole.

[0013] Compared with the prior art, the beneficial technical effects of the present utility model are as follows:

[0014] In the present utility model, opposite accommodation grooves are provided on the opposite joint surfaces of two adjacent clip monomers. An activity plate is hinged inside the accommodation groove. The opposite sides of the two opposite activity plates are respectively an N pole and an S pole, so that when the two adjacent clip monomers are installed, they are adsorbed and connected by the opposite activity plates, and are not easily dropped, and at the same time, it does not affect the mutual approach and clamping of the two adjacent clip monomers.

[0021] Among them, the drawings are only for illustrative purposes, showing only schematic diagrams, rather than physical diagrams, and should not be construed as a limitation of this patent; in order to better illustrate the embodiments of the present utility model, some components in the drawings will be omitted, enlarged or reduced, and do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0022] In the drawings of the embodiments of the present utility model, the same or similar reference numerals correspond to the same or similar components; in the description of the present utility model, it should be understood that if terms such as "upper", "lower", "left", "right", "inner", "outer", etc. are used to indicate the orientation or positional relationship, it is based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the drawings are only for illustrative purposes and cannot be understood as a limitation of this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0023] In the description of the present utility model, unless otherwise clearly specified and defined, if terms such as "connection" are used to indicate the connection relationship between components, this term should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] As Figures 1-4 shown, one specific embodiment of a self - sucking anchor jaw of the present utility model includes at least two jaw monomers 1, generally two or three jaw monomers 1 are used, and all the jaw monomers 1 can be assembled into a jaw assembly 2. The jaw monomers 1 in the same jaw assembly 2 have the same shape. The outer contour shape of the jaw assembly 2 is frustum - shaped, and there is a through - hole 3 at the central axis of the jaw assembly 2. When in use, the wire passes through the through - hole 3. The frustum - shaped jaw assembly 2 is stuck in the anchor ring. As the pulling force increases, the area of the jaw assembly 2 closes, and the through - hole 3 becomes smaller, clamping the wire tighter and tighter. A thread 9 is formed on the inner wall of the through - hole 3 to increase the friction with the wire.

[0025] More specifically, in order to prevent the clip monomer 1 from falling off easily during assembly, the clip monomer 1 includes a fitting surface 4, and the fitting surfaces 4 of two adjacent clip monomers 1 can be mutually fitted. A plurality of accommodation grooves 5 are formed on the fitting surface 4, and the accommodation grooves 5 on the two mutually fitted fitting surfaces 4 correspond to each other. An activity plate 6 is hinged in the accommodation groove 5 through a rotating shaft 7, and the activity plate 6 has magnetism; the rotating shaft 7 is installed on one side of the activity plate 6, so that the other side of the activity plate 6 can be turned outwards. The activity plate 6 has two states of turning inside and outside the accommodation groove 5. When the activity plate 6 turns inside the accommodation groove 5, the outer surface of the activity plate 6 is flush with the corresponding fitting surface 4, so that two adjacent clip monomers 1 can be completely fitted, and the clip assembly 2 can reach the smallest state. The activity plates 6 on the two mutually fitted fitting surfaces 4 face in two opposite directions respectively, and the opposite sides of the activity plates 6 on the two mutually fitted fitting surfaces 4 are respectively the N pole and the S pole, that is, the opposite side of the activity plate 6 on one fitting surface 4 is the N pole, and the opposite side of the activity plate 6 on the other fitting surface 4 is the S pole. Conversely, the opposite side of the activity plate 6 on one fitting surface 4 is the S pole, and the opposite side of the activity plate 6 on the other fitting surface 4 is the N pole. When the two fitting surfaces 4 approach each other, the two opposite activity plates 6 can be turned outwards due to the suction force and attracted together, so as to temporarily fix two adjacent clip monomers 1. When the distance between the clip monomers 1 is compressed, the two mutually adsorbed activity plates 6 will slide relative to each other under the action of an external force, without affecting the mutual fitting of the clip monomers 1.

[0026] The contour of the accommodation groove 5 is larger than that of the activity plate 6, and the two contour shapes are the same, so that the activity plate 6 can freely enter and exit the accommodation groove 5, which is relatively flexible. The plurality of accommodation grooves 5 on the same clip monomer 1 are arranged in sequence from top to bottom, and the sizes of the accommodation grooves 5 gradually decrease from top to bottom, so that each part of the clip monomer 1 is attracted by the activity plate 6, improving the suction force.

[0027] An isolation layer 8 is embedded in the accommodation groove 5 to reduce the influence of the material of the clip monomer 1 itself on the activity plate 6.

[0028] In some other embodiments, the clip monomer 1 itself also has magnetism, and the two adjacent joint surfaces 4 are respectively an N pole and an S pole, that is, if one of the two adjacent joint surfaces 4 is an N pole, then the other joint surface 4 is an S pole, and vice versa, if one of the joint surfaces 4 is an S pole, then the other joint surface 4 is an N pole. More specifically, the joint surface 4 and the outer side of the movable plate 6 on this joint surface 4 are of the same pole, so that they can be adsorbed on the opposite joint surface 4 and the movable plate 6 in the same way. During the construction preparation process, the overall clip 2 is relatively small and is likely to be lost during use. After the design is improved, the overall clip 2 of the self - absorbing type anchor clip in this embodiment can be self - adsorbed in the anchor ring at any time. During the installation process, the clip monomer 1 can be self - adsorbed on the linear magnetic material to quickly install and fix the anchor ring and bear the force. At the same time, two adjacent clip monomers 1 are adsorbed and connected by the movable plate 6. When the structural anchor releases the force, its clip monomer 1 is not likely to fall off and be lost either.

[0029] The embodiments described above are only descriptions of the preferred modes of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
