[0025] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0026] Combination Figure 1 and Figure 3 The embodiment of the utility model provides a clamp 100 for fixing a cable 210. The material of the clamp 100 includes cast iron, carbon steel, plastic, aluminum alloy, etc., and its surface can be treated with anti-corrosion to make it have good corrosion resistance and durability.

[0027] The clamp 100 includes a support member 110 and a fixing member 120. The support member 110 includes a first support portion 111, a second support portion 112 and a first limiting portion 113 which are connected in sequence. The first support portion 111 and the second support portion 112 are combined to form an installation groove 160. The support member 110 provides a stable platform for the installation of the cable 210 to prevent the cable 210 from shaking and dislocating due to external forces.

[0028] The fixing member 120 includes a fixing portion 121 and a second limiting portion 122 connected to each other. The fixing portion 121 is assembled in the mounting groove 160, and the fixing portion 121 abuts against the side of the first supporting portion 111 facing the first limiting portion 113. The first limiting portion 113 and the second limiting portion 122 enclose a limiting groove 130, and the limiting groove 130 is used for passing the cable 210. The fixing member 120 and the supporting member 110 cooperate with each other, and the limiting groove 130 clamps the cable 210 therein to prevent the cable 210 from shaking and dislocating.

[0029] The first support portion 111 abuts against the fixing member 120 in the radial direction of the cable 210 ( Figure 1 The fixing member 120 is squeezed in the left and right directions (in the center), thereby reducing the activity space of the cable 210 in this direction, thereby preventing the cable 210 from shaking and dislocating in the radial direction.

[0030] There are many ways to connect the support member 110 and the fixing member 120, the more common ones are threaded connection, plug-in connection, welding, and bonding. According to the actual situation, one connection method or a combination of multiple methods is selected, and no strict limitation is made here.

[0031] When installing cable 210, the following steps should be strictly followed:

[0032] 1. Determine the location and quantity of the clamps 100 to be used. Determine the location and quantity of the clamps 100 to be used according to actual needs to ensure the firmness and stability of the cable 210.

[0033] 2. Install the clamp 100. Install the clamp 100 at a suitable location of a building or other structure, and then fix it with parts such as bolts and washers, or use other connection methods.

[0034] 3. Clamp the cable 210 . Place the cable 210 into the clamp 100 , and clamp the clamp 100 using the above connection method to ensure that the cable 210 is firmly fixed in the clamp 100 .

[0035] 4. Adjust the position of the cable 210. Adjust the position of the cable 210 as needed to achieve an ideal fixing effect.

[0036] 5. Regular inspection: Regularly check the fixing conditions of the clamp 100 and the cable 210, and deal with any problems in a timely manner to ensure the safety and reliability of the construction.

[0037] Compared with the prior art, the embodiment of the utility model has the following beneficial effects: the first limiting portion 113 and the second limiting portion 122 are combined to form a limiting groove 130, and the cable 210 is inserted into the limiting groove 130, so that the connection position of the cable 210 is fixed, thereby preventing the cable 210 from being dislocated in the axial direction due to shaking; the second supporting portion 112 provides a stable installation platform for the fixing member 120, which facilitates the stable connection of the fixing member 120; the fixing member 120 is inserted into the installation groove 160, and the first supporting portion 111 provides an extrusion to the fixing member 120, thereby pressing the limiting groove 130, thereby preventing the cable 210 from being loosened in the radial direction and causing dislocation, that is, preventing the cable 210 from being loosened in the axial and radial directions, thereby improving the stability of the cable 210.

[0038] Combination Figure 2 In some embodiments, the first support portion 111 is formed with a side wall A toward the first limiting portion 113, and the second support portion 112 is formed with a side wall B toward the fixing portion 121. The side wall A and the side wall B enclose an installation groove 160. The installation groove 160 provides space for the assembly of the fixing member 120. The fixing member 120 is blocked on both sides in the installation groove 160, and the installation position is limited, which helps to firmly connect the fixing member 120 to the support member 110.

[0039] The fixing portion 121 is formed with a side wall C away from the second limiting portion 122, and the fixing portion 121 is formed with a side wall D toward the second supporting portion 112, the side wall C abuts against the side wall A, and the side wall D abuts against the side wall B. The side wall C can fit the side wall A and slide up and down on the inclined plane where the side wall A is located, so as to facilitate the positioning and installation of the fixing member 120. Since it can slide up and down, the aperture size of the limiting groove 130 can be appropriately changed, and the diameter of the cable 210 adapted thereto can be various, thus increasing the range of cables 210 adapted to the clamp 100 and improving the versatility of the clamp 100.

[0040] Generally speaking, when the fixing member 120 and the supporting member 110 are tightened, the side wall D abuts against the side wall B, and the two fit together to effectively limit the position of the fixing member 120, thereby limiting the position of the limiting groove 130 and the cable 210. If a gap is found between the side wall D and the side wall B during installation or maintenance, it is necessary to check the connection firmness of the clamp 100 and replace parts if necessary.

[0041] Specifically, in some embodiments, the side wall A and the side wall B form an angle α, 90<α≤170°.

[0042] Taking steel strands as an example, the most commonly used steel strands are galvanized steel strands and prestressed steel strands. The diameter of commonly used prestressed steel strands is in the range of 9.53mm-17.8mm, and there are a small number of thicker and larger diameter steel strands. Each prestressed steel strand generally has 7 steel wires, but there are also 2, 3, and 19 steel wires. The steel wires can have a metal or non-metal anti-corrosion layer. Therefore, the size of the limit groove 130 needs to be appropriately enlarged or reduced to cope with the installation of cables 210 of different sizes.

[0043] In this embodiment, considering that when α=90°, that is, when side wall A and side wall B form a right angle, the fixing member 120 and the supporting member 110 can only move vertically up and down, the accuracy and smoothness of installation are low, and the vertical movement is not conducive to the enclosure of the installation groove 160, this value is discarded.

[0044] The angle α is preferably an obtuse angle, because at an obtuse angle, the movement of the fixing member 120 includes two situations: up and down movement and left and right movement. The fixing member 120 can move from left to right while moving from top to bottom, that is, the installation of the fixing member 120 and the enclosure of the limiting groove 130 are taken into account; it can move from right to left while moving from bottom to top, that is, the disassembly of the fixing member 120 and the separation of the limiting groove 130 are taken into account, which facilitates the installation, disassembly and adjustment of the cable 210 and the clamp 100. The specific value of α can be selected from 120°, 135°, 150°, and 170°. When the value of α exceeds 170°, the side wall A and the side wall B are close to coplanar, and the first limiting portion 113 loses its meaning of being set.

[0045] It is understandable that in some embodiments, an anti-skid structure is provided between the side wall A and the side wall C. The optional manners include increasing the roughness of the surface of the side wall A and the side wall C, providing a concave-convex structure on the surface of the side wall A and the side wall C, or applying a blocking substance. The purpose of providing an anti-skid structure or performing an anti-skid treatment is to prevent the fixing member 120 from sliding along the side wall A under the action of an external force, causing the limit groove 130 to deform and the cable 210 to dislocate.

[0046] Combination Figure 3 In some embodiments, an anti-skid groove 117 is provided at the connection between the side wall A and the side wall B, and an anti-skid ridge 125 is provided at the connection between the side wall C and the side wall D, and the anti-skid ridge 125 is embedded in the anti-skid groove 117. When the fixing member 120 is installed on the supporting member 110, the two are easy to slide and misalign at the intersection of the horizontal plane and the inclined plane due to the small contact surface, so it is necessary to set a ridge structure to increase the contact surface. The working principle of the anti-skid groove 117 is similar to that of the mounting groove 160, which will not be repeated here. By embedding the anti-skid ridge 125 in the anti-skid groove 117, the firmness of the fixing member 120 on the supporting member 110 is improved.

[0047] Combination Figure 3Based on the same reason as the anti-slip groove 117, in some embodiments, a limiting groove 116 is provided inside the first limiting portion 113, and a limiting protrusion 124 is provided on the second limiting portion 122, and the limiting protrusion 124 is embedded in the limiting groove 116. The limiting protrusion 124 is embedded in the limiting groove 116, and the contact area of ​​the support member 110 and the fixing member 120 in the process of the limiting groove 130 is increased, which is beneficial to the stability of the connection between the support member 110 and the fixing member 120, and the limiting protrusion 124 and the limiting groove 116 can only be separated from the right to the left, while the first limiting portion 113 applies a force from the left to the right to the fixing member 120, so that the limiting protrusion 124 and the limiting groove 116 will not be separated in a normal state, that is, the position of the limiting groove 130 is stable and unchanged, which increases the stability of the installation of the cable 210.

[0048] Combination Figure 2 In some embodiments, the clamp 100 includes a first connecting member 140, and the support member 110 is provided with a first through hole 114. The first connecting member 140 is used to pass through the frame 220 and then cooperate with the first through hole 114 to clamp the frame 220. In this embodiment, the first connecting member 140 is a bolt, which passes through the frame 220 and the support member 110 to fix the two. The connection method is a threaded connection, which is simple and convenient and can quickly fix the position of the support member 110. In other embodiments, the first connecting member 140 can use an adhesive plate, which adheres the support member 110 to the frame 220, and the installation process is also very simple.

[0049] In some embodiments, the clamp 100 includes a second connecting member 150, the fixing member 120 is provided with a second through hole 123, the supporting member 110 is provided with a third through hole 115, the second through hole 123 and the third through hole 115 are arranged opposite to each other, and the second connecting member 150 is passed through the second through hole 123 and cooperates with the third through hole 115. In this embodiment, the second connecting member 150 adopts a bolt, and a through hole is provided at the position where the fixing member 120 and the supporting member 110 are connected. The fixing member 120 and the supporting member 110 are firmly connected by a threaded connection to prevent relative sliding between the two. In other embodiments, the second connecting member 150 can also adopt a buckle or a lock, and the support member 110 and the fixing member 120 can also be simply and quickly fixed by a buckle connection or a lock connection.

[0050] In some embodiments, the limiting groove 130 is circular or elliptical. If the limiting groove 130 is circular, the radial force received by the cable 210 is uniform and consistent, which can prevent the cable 210 from being severely worn at a specific position. If the limiting groove 130 is elliptical, the cable 210 can obtain a certain amount of activity space, which can prevent the cable 210 from being suddenly broken due to being too tight. The specific shape to be used needs to consider the actual use environment and purpose, and is not strictly limited here.

[0051] The utility model also proposes a support structure 200, which includes a cable 210, a frame 220 and the above-mentioned clamp 100. The clamp 100 is connected to the frame 220. The clamp 100 provides a determined installation position for the cable 210. The cable 210 is passed through the clamp 100, and the installation position is determined to avoid shaking and dislocation due to external force. The support structure 200 can be used in buildings, bridges, roads, photovoltaics and other directions, especially photovoltaic construction, and has the characteristics of simple structure, economical and cheap, quick installation, good stability and the like.

[0052] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0053] 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.
