Referring to fig. 1-7, an embodiment of the present invention is provided, which includes a threaded sleeve 1 for fixedly mounting in a plate and having an inner wall thread 12, and a fixing sleeve 2 for fixedly mounting on an end surface of another plate, wherein the threaded sleeve 1 is mounted at a designated position of the plate, an installation groove adapted to the fixing sleeve 2 is formed at the designated position on the end surface of the other plate, and the fixing sleeve 2 is inserted into the installation groove.
An inner long groove 21 is formed in the fixing sleeve 2 from the opening at one end to the inside of the other end of the fixing sleeve, one end of the opening of the inner long groove 21 in the fixing sleeve 2 is located on the end face of the other plate, a through groove 22 which is perpendicular to and communicated with the inner long groove 21 is further formed in the fixing sleeve 2, and the inner long groove 21 and the through groove 22 are located in the same plane and are communicated with each other.
A fastener 6 is disposed in the channel 22 and is movable inwardly for tightening. A cutting sleeve 5 matched with the fastener 6 is arranged in the through groove 22, and through holes 51 for the connecting rod 4 to pass through are formed in two opposite sides of the side wall of the cutting sleeve 5. When installed, the two through holes 51 correspond to the inner long groove 21, so that the connecting rod 4 can pass through the ferrule 5 and can move in the inner long groove 21. The inner wall of the cutting sleeve 5 is provided with an internal thread 52, and the outer wall of the fastening piece 6 is provided with an external thread 61 which is meshed with the internal thread 52. The cutting ferrule 5 is fixed in the through groove 22, or movably mounted in the through groove 22, and the connection mode can be selected according to different requirements, so that the cutting ferrule 5 and the through groove 22 are integrated or split. The inner wall of the through groove 22 can also be directly provided with a thread matched with the external thread 61, so that the arrangement of the cutting sleeve 5 is eliminated.
When tightening the fastener 6, the fastener 6 moves inwardly along the inner wall of the ferrule 5, the inner end of the fastener 6 moves inwardly, so that the space between the inner end of the fastener 6 and the inner end face of the ferrule 5 is reduced; when loosening the fastener 6, the fastener 6 moves up the inner wall of the ferrule 5 and the inner end of the fastener 6 moves outward, increasing the space between it and the inner end surface of the ferrule 5.
The trompil has been seted up with the position that leads to groove 22 corresponding in the surface of another panel for installation fastener 6, cutting ferrule 5 and fastener 6 form the bulge when installing logical inslot 22, and the bulge is located the downthehole portion of card, and is spacing to fixed external member 2, will fix external member 2 chucking in the mounting groove of another panel terminal surface, makes fixed external member 2 fixed connection in another panel.
The inner bottom end of the inner long groove 21 is provided with a spring 3 which is in contact with one end of the inner wall of the inner long groove 21, the connecting rod 4 which extends into the clamping sleeve 5 from one end of the opening of the inner long groove 21 and penetrates through the clamping sleeve 5 is further arranged, the inner end of the connecting rod 4 is in contact with one end of the spring 3, elasticity can be generated on the connecting rod 4, the position of the connecting rod 4 can be adjusted, when the connecting rod 4 moves in the inner long groove 21, the spring 3 is compressed, and a certain space can be provided for the movement of.
A threaded rod 42 which can be in threaded connection with the inner wall of the threaded sleeve 1 is arranged at the outer end of the connecting rod 4 extending out of the opening of the inner elongated slot 21, the threaded rod 42 is in threaded connection with the inner wall of the threaded sleeve 1 to connect the two plates, and a chute 41 which can tension the connecting rod 4 inwards when the fastener 6 is tightened inwards is further arranged at the position, located in the clamping sleeve 5, of the connecting rod 4. Chute 41 on connecting rod 4 distributes a week around the surface of connecting rod 4 for no matter what angle connecting rod 4 is in, the bottom of fastener 6 can both correspond to chute 41, avoids connecting rod 4 to rotate and leads to chute 41 to be in the position that does not correspond with fastener 6. The inner end of the fastener 6 is arc-shaped, so that the friction force between the fastener and the chute 41 is reduced, and the connecting rod 4 can move conveniently. The depth of the inclined groove 41 gradually increases from the two ends to the middle. When the fastener 6 is in a loose state, the shallow part of the inner end of the chute 41 is positioned at the bottom end of the fastener 6, when the fastener 6 is screwed, the depth of the fastener 6 is gradually increased, and extrusion force is generated, so that the chute 41 needs to correspond the deepest part to the position of the fastener 6, and enough space is generated for the fastener 6 to move, and the connecting rod 4 is driven to move towards the inside of the inner elongated slot 21.
During installation, the threaded rod 42 is stably connected with the inner wall of the threaded sleeve 1 in a threaded manner, one end of the fixing rod 4 is inserted into the inner long groove 21 and penetrates through the clamping sleeve 5 to be contacted with the spring 3, the fastener 6 is installed from the clamping opening of the clamping sleeve 5, at the moment, the shallowest position of the chute 41 on the connecting rod 4 is located at the position of the bottom end of the fastener 6, the fastener 6 is screwed, the fastener 6 moves inwards to press the chute 41, along with the penetration of the fastener 6, the bottom end of the fastener 6 gradually extrudes the chute 41 to enable the deepest part of the chute 41 to gradually move towards the bottom end of the fastener 6, the connecting rod 4 moves towards the inner long groove 21, finally, the bottom end of the fastener 6 presses the deepest part of the chute 41, the connecting rod 4 is pulled inwards to the deepest part, the connecting rod 4 drives the threaded sleeve.
Further, the outer wall of the thread bush 1 is provided with an outer wall thread 11 for fixing with a plate material, and one end inside the thread bush 1 is provided with an inner groove 13 for installing the thread bush 1 into the plate material. The internal groove 13 may be a hexagonal or pentagonal groove or another groove that does not interfere with the entry of the threaded rod 42 into the interior of the threaded groove 1. The threaded sleeve 1 is mounted to the sheet material at a designated position by screwing it with a tool so that the end face of the threaded sleeve 1 is flush with the surface of the sheet material.
Further, the outer end face of the fastener 6 is provided with a snap groove 62 for tightening and fixing. The slot 62 may be an internal hex slot, an internal pentagonal slot, or a different slot to facilitate driving of the fastener 6 with a tool.
Further, both ends of the through groove 22 penetrate the outer wall surface of the fixing kit 2, or one end of the through groove 22 penetrates the outer wall surface of the fixing kit 2. That is, the through groove 22 may be open at both ends or only one end, and may be machined and manufactured according to different use requirements.
The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and all equivalent structural changes made by using the contents of the present specification and the drawings, or any other related technical fields, are included in the scope of the present invention.
