[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0023] As Figures 1-4 shown, the combined embedded sleeve provided in this embodiment mainly includes a table body 1, a connecting mechanism 2, a docking groove 3, a fixing mechanism 4 and a second groove 5.
[0024] Table body 1, a docking groove 3 is opened at one end of the table body 1.
[0025] A pit 5 is provided on the outer side of the table body 1.
[0026] The pit 5 on the frustum 1 is chiseled out with a tool. On the one hand, it is convenient for positioning during installation, and on the other hand, it prevents the thread from loosening.
[0027] The connecting mechanism 2 is arranged at one end of the frustum 1, and connecting it with the frustum 1 will increase the resistance to being pulled out from the concrete.
[0028] The connecting mechanism 2 includes a frustum 201, a first groove 202, a connecting body 203 and a second groove 204. The frustum 201 is rotatably connected to one end of the frustum 1. The first groove 202 is opened at one end of the frustum 201. The connecting body 203 is fixedly connected to the outside of the frustum 201. The second groove 204 is opened at the other end of the frustum 201.
[0029] The overall shape of the first groove 202 on the frustum 201 is circular or polygonal. The connecting body 203 is a reinforcing rib to prevent rotation in the concrete.
[0030] The outer surface of the frustum 201 is provided with threads, and there are concave points on the thread surface of the frustum 201, corresponding to the pits 5 on the frustum 1 to prevent the threads from loosening.
[0031] There is a flat opening on the frustum 201, which can be on two sides or four sides, to prevent the frustum 1 and the frustum 201 from rotating in the concrete.
[0032] Align the threads on the frustum 201 with the threads on the frustum 1, and rotate the frustum 201 into the frustum 1. Considering that the threaded connection may cause the frustum 1 and the frustum 201 to rotate and loosen, there are concave points on the thread surface of the frustum 201, and the pits 5 on the frustum 1 correspond to the concave points on the thread surface of the frustum 201 to prevent the frustum 1 and the frustum 201 from loosening. The connecting body 203 is a reinforcing rib, and the connecting body 203 can prevent the frustum 1 and the frustum 201 from rotating in the concrete. The first groove 202 and the second groove 204 on the frustum 201 reduce the overall weight on the one hand, and are convenient for positioning during installation on the other hand. At the same time, the frustum 1 and the frustum 201 form two protruding parts as a whole, which will increase the resistance to being pulled out from the concrete and increase the overall pulling force.
[0033] The fixing mechanism 4 is arranged inside the frustum 1, and the external component is fixed inside the frustum 1 through the fixing mechanism 4.
[0034] The fixing mechanism 4 includes a clamping block 401 and a clamping groove 402. The clamping block 401 is fixedly connected inside the frustum 1, and the clamping groove 402 is opened at one end of the clamping block 401.
[0035] The bottom end of the clamping groove 402 on the clamping block 401 is set as a plane, a dovetail surface or a serrated surface.
[0036] Align the external component with the docking groove 3 on the table body 1. Then, insert the external component into the docking groove 3 on the table body 1. Next, rotate the external component 90 degrees within the table body 1. There is a serrated surface on the external component corresponding to the serrated surface in the card slot 402 of the clamping block 401. Align the serrated surface on the external component with the serrated surface in the card slot 402 of the clamping block 401. Pull the external component outwards slightly, causing the serrated surface on the external component to move towards the card slot 402 of the clamping block 401, so that the serrated surface on the external component bites into the serrated surface in the card slot 402 of the clamping block 401, thus fixing the external component on the clamping block 401 for connecting other objects to the external component.
[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
