Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and in particular relates to a self-locking angle connector. Background Art

[0002] At present, in order to prevent rain from damaging the equipment, outdoor equipment needs to build a protective box for it. Before setting up the box, a frame needs to be built. Currently, it is usually built with aluminum profiles and corner connectors, and then the box panels are laid and fixed with screws. The corner connectors generally play a pre-connection role.

[0003] The existing corner connectors are loose or difficult to insert after being inserted, and thus a corner connector is needed which is easy to insert at the beginning and locked after being fully inserted. Utility Model Content

[0004] In order to solve the above technical problems, the utility model further proposes a self-locking angle connector.

[0005] The specific technical solution of the utility model is as follows: A self-locking angle connector, comprising:

[0006] An angular connector body, wherein two angular end surfaces of the angular connector body are each provided with a receiving chamber for receiving a self-locking unit;

[0007] The self-locking unit comprises: a self-locking body, a driving cavity and an extrusion cavity are arranged on the side wall of the self-locking body, a driving block and an extrusion block are slidably arranged in the driving cavity and the extrusion cavity respectively, the driving cavity and the extrusion cavity are connected through a hydraulic channel, a plurality of through holes corresponding to the positions of the driving cavity and the extrusion cavity are arranged on the angle connector body, a transmission medium is arranged in the driving cavity, the extrusion cavity and the hydraulic channel, and the driving cavity is located at a position away from the end of the angle connector body.

[0008] Furthermore, one end of the hydraulic channel is arranged on the end surface of the self-locking body and is blocked by a locking plug, and the other end of the hydraulic channel is a closed end.

[0009] Furthermore, the hydraulic channel is threadedly connected to the locking plug.

[0010] Furthermore, the self-locking body is connected to the corner connector body by bolts or clamps.

[0011] Furthermore, a connecting block is provided on the driving block, and a guiding surface for facilitating the insertion of the profile is provided at one end of the connecting block.

[0012] Furthermore, the end surface of the extrusion block is provided with anti-slip textures.

[0013] Furthermore, the corner connector body is provided with material reduction holes for reducing material usage.

[0014] Furthermore, reinforcing ribs are arranged in the material-reducing holes.

[0015] Furthermore, the corner connector body is provided with a snap-in groove for connecting with the matching profile.

[0016] Beneficial effects:

[0017] 1. The present application sets the driving cavity at a position far away from the end of the corner connector body, so that the end encounters less resistance when initially inserted into the profile. When the profile contacts the connecting block, the driving block is driven to move and then the extrusion block is driven to extend outward to extrude the profile, thereby increasing the friction force, and making it difficult for the corner connector to fall off from the profile.

[0018] 2. The present application is provided with a locking plug. When the locking plug is removed or moved outward, the driving block and the extrusion block are recovered to reduce the pressure on the inner wall of the profile, making it easy to remove. BRIEF DESCRIPTION OF THE DRAWINGS

A sealing ring is arranged between the driving block 24 and the extrusion block 25 and the driving chamber 22 and the extrusion chamber 23. The driving chamber 22 and the extrusion chamber 23 are connected through a hydraulic channel 26. The corner connector body 1 is provided with a plurality of through holes 12 corresponding to the positions of the driving chamber 22 and the extrusion chamber 23.

The driving chamber 22, the extrusion chamber 23 and the hydraulic channel 26 are provided with a transmission medium. The transmission medium adopts hydraulic oil or other liquid medium, and the medium that meets the actual installation environment can be used. The driving chamber 22 is located at a position away from the end of the corner connector body 1. One end of the hydraulic channel 26 is arranged on the end surface of the self-locking body 21, and is blocked by a lock plug 27. The other end of the hydraulic channel 26 is a closed end. The hydraulic channel 26 is threadedly connected to the lock plug 27. The self-locking body 21 is connected to the corner connector body 1 by bolts or clamping.
