Technical Field

[0001] This invention belongs to the technical field of fixing clamps, and particularly relates to a clamp. Background Technology

[0002] A clamp is a type of fastener. Currently, there are generally two types of clamps: one is composed of two semi-circular clamp plates, which are fixed at both ends with bolts; the other is a chain clamp composed of multiple clamp plates, which are fixed together at both ends with bolts to form a complete clamp. When in use, the clamp clamps tightly grip the support column.

[0003] Chinese Patent CN111197613A discloses a clamp for installing communication equipment, comprising at least two clamp units, internal connectors, edge connectors, and a locking device. The clamp units are connected in pairs via internal connectors to form a clamp chain. Edge connectors are installed at both ends of the clamp chain, and the edge connectors are connected to the locking device. The clamp units are provided with expansion connection holes for connecting other parts. In this technical solution, the clamp clamps hold a support member, and then connects to the fixed part through the expansion connection holes on the clamp units, thereby fixing the fixed part.

[0004] In the above technical solutions, when the fixed part is connected to the hoop unit through the expansion connection hole, bolt connection is usually used, which makes the operation of adjusting the position of the fixed part on the hoop cumbersome and inconvenient. Summary of the Invention

[0005] To address the problems mentioned above in the background art, the present invention provides a clamp that has the advantage of facilitating the adjustment of the fixed component.

[0006] This invention is achieved through the following technical solution:

[0007] A type of clamp, including,

[0008] A hoop chain, comprising at least two hoop plates that can be connected end to end;

[0009] The guide rail is mounted on the hoop chain;

[0010] The slider is slidably connected to the guide rail.

[0011] As a further explanation of the invention: each set of guide rails includes at least two guide blocks, which are arranged corresponding to the clamps.

[0012] As a further explanation of the invention: the slider includes a grooved plate and a limiting block disposed opposite to the inner side of the opening of the grooved plate, and a gap is left between the guide block and the slider.

[0013] As a further explanation of the invention: the slider includes a grooved plate and a limiting block and a limiting post disposed opposite to each other inside the opening of the grooved plate. At least one limiting post is provided, and the limiting post is detachably disposed. A gap is left between the guide block and the slider.

[0014] As a further explanation of the invention: the guide block is disposed on the hoop, and the guide block has a T-shaped cross-section along the transverse direction of the hoop chain.

[0015] As a further explanation of the invention: guide grooves are provided on the inner sides of the upper and lower ends of each of the hoop pieces, and guide blocks are formed on both the upper and lower sides of the hoop piece.

[0016] As a further explanation of the invention: pads are provided on the inner side of the hoop chain to form guide blocks at the upper and lower ends of the hoop chain.

[0017] As a further explanation of the invention: the guide block is disposed on the upper or lower side of the guide rail, and the distance between the guide block and the support column is greater than the thickness of the limiting block.

[0018] As a further explanation of the invention: the guide block is disposed on the upper or lower side of the guide rail, a pad is disposed on the inner side of the hoop chain, and the distance between the guide block and the support column is greater than the thickness of the groove plate.

[0019] As a further explanation of the invention: the guide block is disposed on the outside of the hoop, and the distance between the guide block and the support column is greater than the thickness of the limiting block.

[0020] As a further explanation of the invention: a pad is provided on the inner side of the hoop chain, and the distance between the hoop plate and the support column is greater than the thickness of the limiting block.

[0021] As a further explanation of the invention: one end of the guide block is provided with an inner tangent surface, and the other end is provided with an outer tangent surface that matches the inner tangent surface.

[0022] As a further explanation of the invention: one end of the guide block along the length of the hoop chain is provided with an arc-shaped groove, and the other end is provided with an arc-shaped protrusion corresponding to the arc-shaped groove.

[0023] As a further explanation of the invention: one end of the guide block along the length of the hoop chain is provided with an arc-shaped groove, and the other end is provided with an arc-shaped protrusion corresponding to the arc-shaped groove.

[0024] As a further explanation of the invention: a fixing device is provided between the guide rail and the hoop chain.

[0025] As a further explanation of the invention: one end of the hoop chain is connected to an edge connector, and the other end is connected to at least one telescopic rod I corresponding to the edge connector. The telescopic rod I is fixedly connected to the edge connector, and both ends of the telescopic rod I are set as lifting rings.

[0026] As a further explanation of the invention: a telescopic rod II is provided between the two ends of the hoop chain, one end of the telescopic rod II is set as a lifting ring, and the other end is set as a grooved lifting ring.

[0027] Compared with the prior art, the present invention has the following beneficial technical effects:

[0028] 1. After the hoop chain is connected end to end to form a closed loop, it will be fixed on the support. At this time, the slider can still slide along the length of the hoop chain through the guide rail to adjust the position of the fixed part, thus realizing the rapid adjustment of the fixed part.

[0029] 2. When the guide block is T-shaped along the transverse section of the hoop chain and is located on the outside of the hoop chain, an inner tangent and an outer tangent are respectively set at both ends of the guide block. After the guide rail bends with the hoop chain, the outer tangent part is still within the inner tangent, ensuring the continuity of the guide rail. Similarly, regardless of whether the guide rail is set as T-shaped or formed by inner tangents on the upper and lower sides of the hoop plate, when the guide rail is located on the upper and lower sides of the hoop chain, an arc-shaped protrusion is set at one end of the guide block and an arc-shaped groove is set at the other end, so that the guide rail can be bent without gaps between the guide blocks, and the guide rail has good continuity after bending.

[0030] 3. The slider includes a channel plate and a limiting block and a limiting post disposed opposite to each other inside the opening of the channel plate. At least one limiting post is provided to prevent the slider from falling off the guide rail, which improves the reliability of the device. After the limiting post is removed, even after the hoop chain forms a closed loop, the slider can still be installed at any point on the guide rail. It is not necessary to assemble the slider from the end of the hoop chain to the guide rail when the hoop chain is in the open state. At the same time, after the hoop is installed, the slider can be removed without disconnecting the hoop chain, which facilitates the disassembly and assembly of the slider.

[0044] like Figures 1 to 7 As shown,

[0045] Example 1:

[0046] A chain clamp, comprising:

[0047] The hoop chain includes at least two hoop plates 1 that can be connected end to end; one end of the hoop chain is connected to an edge connector 5, and the other end is connected to at least one telescopic rod I4 corresponding to the edge connector 5. The telescopic rod I4 is fixedly connected to the edge connector 5, and both ends of the telescopic rod I4 are provided with lifting rings. Specifically, multiple hoop plates 1 are provided, and the telescopic rod I4 includes a threaded tube and threaded rods threaded to both ends of the threaded tube. Pull rings are provided at the ends of the threaded rods that are far apart from each other. The threads of the two threaded rods have opposite directions, and the internal threads at both ends of the threaded tube are provided corresponding to the two threaded rods.

[0048] A guide rail is mounted on the chain; each set of guide rails includes at least two guide blocks 2, which are positioned corresponding to the hoop pieces 1. A fixing device is provided between the guide rail and the chain. Specifically, adjacent hoop pieces 1 are rotatably connected by cylindrical pins, the guide blocks 2 are positioned corresponding to the hoop pieces 1, and the fixing device is a set screw 31. The end of the set screw 31 away from its screw head can abut against the hoop piece 1 or the guide rail. The hoop piece 1 and the guide rail are integrally formed and milled by a lathe according to a mold.

[0049] The slider 3 is slidably connected to the guide rail. The slider 3 includes a grooved plate 32 and a limiting block 33 disposed opposite to the inner side of the opening of the grooved plate 32. A gap is left between the guide block 2 and the slider 3. Specifically, the grooved plate 32 and the limiting block 33 are integrally formed. The size of the slider 3 is determined according to the specific guide rail. The slider 3 can be drilled with holes as needed to connect the fixed component.

[0050] Guide block 2 is mounted on hoop 1, and its cross-section along the hoop chain is T-shaped. Guide block 2 is located on the outer side of hoop 1, with an inner tangent surface 221 at one end and an outer tangent surface 222 at the other end that matches the inner tangent surface 221. Specifically, the inner tangent surface 221 is positioned along the axial direction of the hoop chain after forming a closed loop, and is fan-shaped on the side of the guide plate near hoop 1; the corresponding outer tangent surface 222 is also fan-shaped.

[0051] The working principle of this invention is as follows:

[0052] First, slide the slider 3 into the guide rail from the end of the guide rail, and wrap the hoop around the support column. Then, connect the two ends of the hoop with the telescopic rod, and adjust the length of the hoop by the telescopic rod to make the hoop hug the support column. After the hoop forms a closed loop, the guide block 2 will also form a closed loop with the hoop. After the hoop forms a closed loop, part of the outer tangent 222 is still within the inner tangent 221, so that the guide rail is in a continuous state, which improves the reliability of the device. After sliding the slider 3 to the desired position along the guide rail, tighten the set screw 31 so that the end of the set screw 31 away from the screw head presses against the guide rail to complete the positioning of the slider 3. When it is necessary to adjust the position of the fixed part, it can still be achieved by adjusting the position of the slider 3 on the guide rail. When using this device, the slider 3 can also be connected to the support column, and the fixed part can be fixed by the hoop, which can also achieve the adjustment of the fixed part.

[0053] Example 2:

[0054] In this embodiment, except that "the guide block 2 is set on the upper or lower side of the guide rail, and a pad block 11 is set on the inner side of the hoop chain, and the distance between the guide block 2 and the support column is greater than the thickness of the groove plate 32; one end of the guide block 2 along the length of the hoop chain is provided with an arc-shaped groove 24, and the other end is provided with an arc-shaped protrusion 23 corresponding to the arc-shaped groove 24," the rest of the embodiment is exactly the same. Specifically, each guide block 2 is provided with a pad block 11 on its inner side. The pad block 11 is set in the shape of a frustum pyramid. The thickness of the limiting block 33 refers to the diameter direction in which the hoop chain is connected end to end to form a closed loop. Since one end of the guide block 2 is provided with an arc-shaped groove 24 and the other end is provided with an arc-shaped protrusion 23, after the hoop chain forms a closed loop, the arc-shaped protrusion 23 rotates in the arc-shaped groove 24 of the adjacent guide block 2, so that the guide rail is in a continuous state after bending, which has higher reliability.

[0055] Example 3:

[0056] In this embodiment, except that "the guide block 2 is located on the upper or lower side of the guide rail, and the distance between the guide block 2 and the support column is greater than the thickness of the channel plate 32," everything else is exactly the same as in Embodiment 2. Specifically, the thickness of the limiting block 33 refers to the straight line direction perpendicular to the diameter of the limiting block 33 after the hoop chain forms a closed loop.

[0057] Example 4:

[0058] In this embodiment, except that "guide grooves are provided on the inner sides of the upper and lower ends of each hoop 1, and guide blocks 2 are formed on both the upper and lower sides of the hoop 1," everything else is exactly the same as in Embodiment 2. Specifically, along the straight line direction perpendicular to the diameter of the limiting block 33 after the hoop chain forms a closed loop, the size of the guide groove is larger than the size of the limiting block 33.

[0059] Example 5:

[0060] In this embodiment, except for "a pad 11 is provided on the inner side of the hoop chain to form guide blocks 2 on the upper and lower sides of the hoop chain", everything else is exactly the same as in embodiment two. Specifically, the distance between the guide block 2 and the support column is greater than the thickness of the limiting block 33. The thickness of the limiting block 33 refers to the straight line direction perpendicular to the diameter of the limiting block 33 after the hoop chain forms a closed loop.

[0061] In all the above embodiments, slider 3 can be replaced with "slider 3 includes a grooved plate 32 and a limiting block 33 and a limiting post 34 disposed opposite to each other inside the opening of the grooved plate 32, at least one limiting post 34 is provided, and the limiting post 34 is detachably provided." Also, the telescopic rod and edge connector 5 can be replaced with "a telescopic rod II is provided between the two ends of the hoop chain, one end of the telescopic rod II is set as a lifting ring, and the other end is set as a grooved lifting ring." Specifically, three limiting posts 34 are provided, and the limiting posts 34 are hexagonal studs. The telescopic rod II includes a threaded tube and threaded rods threaded to both ends of the threaded tube. A lifting ring is provided at the end of one threaded rod away from the threaded tube, and a grooved lifting ring is provided at the end of the other threaded rod away from the threaded tube. The threads of the two threaded rods have opposite directions, and the internal threads at both ends of the threaded tube correspond to the two threaded rods.
