Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a gripper round pipe connector with multiple locking mechanisms. Background Art

[0002] A gripper tube connector is a mechanical component specifically used to connect and fix round tubes. It is usually designed with a structure that can fit closely to the surface of the round tube to ensure the stability and reliability of the connection. The main function of a gripper tube connector is to firmly connect round tubes of different lengths, diameters or angles together to form the desired structure or frame.

[0003] There are many designs for gripper round tube connectors. Different materials, specifications and connection methods can be selected according to different application scenarios and needs. Common materials include aluminum alloy, stainless steel, etc., which have excellent mechanical properties and corrosion resistance. Connection methods include bolt connection, clamp connection, welding, etc., which can be selected according to actual needs.

[0004] When some existing gripper round tube connectors are in use, the connectors are fastened or disassembled only by means of a snap-on structure. However, such a structure is easily loosened due to accidental contact, which may cause the connectors to lose their original stability and load-bearing capacity.

[0005] For example, the patent publication number CN208456972U discloses a gripper round tube connector that is easy to disassemble and assemble. The gripper round tube connector of this patent is provided with a clamping device, a first movable frame, a second movable frame, a fixed plate, a movable device, a vertical plate, a clamping plate, a support plate and a support groove, so that the clamping plate is clamped inside the support groove, and disassembly is convenient and quick, and does not require the complicated process of disassembling and assembling bolts, thereby improving the work efficiency of the staff.

[0006] The clamping device of the gripper circular tube connector of the patent is mainly composed of a first movable frame, a second movable frame, a fixed plate, a movable device, a vertical plate, a clamping plate and a support plate. This design allows the user to engage or disengage the clamping plate with the support groove by rotating the vertical plate, thereby achieving the tightening or disassembly of the connector. However, since this clamping method depends on the relative position between the components, it is easy to cause position changes due to external factors such as accidental touch, vibration, etc., and then cause loosening. If the clamping device becomes loose during use, it may cause the connector to lose its original stability and load-bearing capacity, thereby causing a safety accident. Especially in connectors that need to withstand large loads or are in critical positions, this loosening may have serious consequences.

[0007] Therefore, it is necessary to invent a gripper round tube connector with multiple locking mechanisms to solve the above problems. Utility Model Content

[0011] Preferably, a telescopic rod is installed inside the limiting bolt, the bottom end of the telescopic rod extends to the outside of the limiting bolt and is fixedly connected with a hemispherical stopper, and the diameter of the hemispherical stopper is larger than the inner diameter of the hand-tightening nut.

[0012] The design of the telescopic rod and the hemispherical stopper can prevent the hand nut from accidentally falling off when the connector is not completely locked, thereby enhancing the safety of the connector.

[0013] Preferably, a snap-lock fixing piece is installed on the top of the ear plate No. 1, the number of the snap-lock fixing pieces is set to two, and the two snap-lock fixing pieces are symmetrically distributed about the center line of the ear plate No. 1.

[0014] The snap-lock fastener provides an additional locking point for the No. 1 ear plate, increasing the firmness of the connector and making the connection more reliable.

[0015] Preferably, a buckle movable part is installed at the bottom of the second ear plate, the number of the buckle movable parts is set to two, and the two buckle movable parts are symmetrically distributed about the center line of the second ear plate.

[0017] Preferably, the buckle lock fixing piece is located above the buckle lock movable piece, and the buckle lock movable piece is buckled with the buckle lock fixing piece.

[0018] After the buckle movable part and the buckle fixed part are buckled together, the stability of the connecting part can be further improved.

[0020] The No. 1 connector and the No. 2 connector are fixed by magnetic force, which enables a quick initial connection, simplifies the operation process, and improves the convenience of connection.

[0021] Preferably, the inner walls of the No. 1 connecting piece and the No. 2 connecting piece are both fixedly connected with an anti-slip layer, and the anti-slip layer is made of rubber material.

[0023] Preferably, dot-shaped protrusions are fixedly connected to the surface of the anti-slip layer, and the dot-shaped protrusions are integrally formed with the anti-slip layer.

[0024] The dot-shaped protrusions increase friction and further enhance the anti-slip effect.
