DETAILED DESCRIPTION

[0049] The utility model is described in detail below in combination with the drawings and examples.

[0050] Example 1

[0051] The embodiment provides a corner type clamp, as shown in the figure, which comprises a clamping assembly 100 and a protection assembly 200. Figure 1

[0052] The clamping assembly 100 comprises a main clamping arm 101 and an auxiliary clamping arm 102.

[0053] The main clamping arm 101 has a connecting portion A 103 and a clamping portion A 104.

[0054] The auxiliary clamping arm 102 has a connecting portion B 105 and a clamping portion B 106.

[0055] The top of the connecting portion A 103 is hinged to the top of the connecting portion B 105. The clamping portion A 104 and the clamping portion B 106 cooperate to clamp the protruding portion of the color steel tile. The clamping portion A 104 is a U-shaped structure, the open end of which faces the clamping portion B 106, and the opposite faces of the U-shaped structure are arranged in an up-down manner.

[0056] Each of the clamping portion A 104 and the clamping portion B 106 is provided with an operation cavity, which is operation cavity A 107 and operation cavity B 108 respectively. The operation cavity A 107 has a strip-shaped opening on the end face facing the clamping portion A 104, and the operation cavity B 108 has a strip-shaped opening on the end face facing the clamping portion B 106.

[0057] As shown in the figure, the protection assembly 200 comprises two placement plates 201, a flat rubber plate 202 and a U-shaped rubber plate 203. Figure 2

[0058] ​​Two placement plates 201 are respectively placed in the operation cavities A107 and B108 and are in sliding fit with the corresponding operation cavities; the end surface of each placement plate 201 is provided with a boss corresponding to the strip-shaped opening of the corresponding operation cavity, and the boss extends from the corresponding strip-shaped opening to be connected with the rubber plate; that is, the flat rubber plate 202 is located outside the operation cavity B108 and is fixedly connected with the boss of the placement plate 201 located in the operation cavity B108; the U-shaped rubber plate 203 is located outside the operation cavity A107 and is fixedly connected with the boss of the placement plate 201 located in the operation cavity A107. The open end of the U-shaped rubber plate 203 faces the flat rubber plate 202, and the two opposite surfaces of the U-shaped rubber plate 203 are arranged in an up-down manner.

[0059] When clamping, the convex part of the color steel tile is located between the flat rubber plate 202 and the U-shaped rubber plate 203, and the flat rubber plate 202 and the U-shaped rubber plate 203 convert the hard contact between the main clamping arm 101 and the color steel tile and the hard contact between the auxiliary clamping arm 102 and the color steel tile into soft contact, thereby reducing the damage of the color steel tile in the process of installing the clamp. At the same time, when the clamp has a tendency of up-down movement due to external vibration, the two opposite surfaces of the U-shaped rubber plate 203 arranged in an up-down manner protect the upper and lower ends of the convex part of the color steel tile, avoiding direct contact with the upper and lower wall surfaces of the clamping part A104.

[0060] As an example, the U-shaped rubber plate 203 and the flat rubber plate 202 are both in a hollow structure (that is, the surfaces of the flat rubber plate 202 and the U-shaped rubber plate 203 are both provided with a grid-shaped or respective holes or gaps), which increases the resilience of the flat rubber plate 202 and the U-shaped rubber plate 203 and further improves the protection of the color steel tile in the process of installing the angle speed clamp.

[0061] As an example, the end surfaces of the U-shaped rubber plate 203 and the flat rubber plate 202 in contact with the color steel tile are both provided with suction cups 204. When the clamp clamps and installs the color steel tile, the suction cups 204 provided on the flat rubber plate 202 and the U-shaped rubber plate 203 will first contact and be extruded with the color steel tile; during the extrusion process, the air in the suction cups 204 is discharged, so that the air pressure in the suction cups 204 (that is, between the contact surfaces of the suction cups 204 and the color steel tile) is less than the atmospheric pressure. Under the action of the atmospheric pressure, the suction cups 204 are firmly adsorbed on the color steel tile, thereby improving the connection performance between the clamp and the color steel tile.

[0062] As an example, the flat rubber plate 202 and the U-shaped rubber plate 203 are both made of ethylene propylene diene rubber material. Since the ethylene propylene diene rubber has good elasticity and resilience, it is suitable for occasions requiring buffering, shock absorption, sealing, etc.

The end face of each mounting and dismounting plate 501 provided with the mounting and dismounting protrusion 503 is in abutment with the placement plate 201.

[0068] In the operation cavity A 107, the telescopic springs 502 on the mounting and dismounting plate 501 are in abutment with the inner wall surface of the operation cavity A 107 and press the placement plate 201; when it is needed to take out the placement plate 201 connected with the flat rubber plate 202, the mounting and dismounting plate 501 is pressed towards the inner wall surface of the operation cavity A 107, the pressing on the placement plate 201 is released, and the placement plate 201 is taken out from the opening end of the operation cavity A 107; in the operation cavity B 108, the telescopic springs 502 on the mounting and dismounting plate 501 are in abutment with the inner wall surface of the operation cavity A 108 and press the placement plate 201; when it is needed to take out the placement plate 201 connected with the U-shaped rubber plate 203, the mounting and dismounting plate 501 is pressed towards the inner wall surface of the operation cavity B 108, the pressing on the placement plate 201 is released, and the placement plate 201 is taken out from the opening end of the operation cavity B 108. That is, the mounting and dismounting assembly 500 makes the clamp convenient for replacement of the flat rubber plate 202 and the U-shaped rubber plate 203, so that the resilience performance of the flat rubber plate 202 and the U-shaped rubber plate 203 caused by aging is avoided, damage of the color steel tile is avoided, so that the protection strength of the color steel tile is maintained, and a series of problems such as rain leakage caused by damage is avoided. Meanwhile, the mounting and dismounting protrusion 503 can close the opening end of the operation cavity A 107 and the operation cavity B 108, so that foreign matters in the outside are avoided from entering the operation cavity A 107 and the operation cavity B 108, the inside of the operation cavity A 107 and the operation cavity B 108 is prevented from being polluted by the outside, and the service life of the clamp is prolonged. In the embodiment, the mounting and dismounting protrusion 503 is triangular in cross section, and material can be saved.
