[0034] Implementation

[0035] Reference Figures 1 to 3 This embodiment is an optional embodiment of the present application, which discloses a pre-buried isolation fixture, including a cable card 1 and a connecting plate 6, wherein the connecting plate 6 is in an L-shaped structure to fit the external structure; at the same time, a plug-in board 7 is also arranged on the connecting plate 6, wherein the plug-in board 7 is in an L-shaped structure, wherein the horizontal section of the plug-in board 7 is integrally connected with the vertical section of the connecting plate 6, and the vertical section of the plug-in board 7 is arranged upward;

[0036] The cable card 1 is provided with a card slot adapted to the cable on one side, and a plug-in slot 8 is provided on the other side thereof, and the plug-in slot 8 is adapted to the plug-in board 7; at the same time, an avoidance slot 11 is also provided on the outer side of the plug-in slot 8, and the plug-in slot 8 is separated from the avoidance slot 11 by a partition, and a square hole is provided on the above partition; an elastic hook 9 is also provided on the cable card 1, and the elastic hook 9 includes a spring piece 901 and a limiting protrusion 902, and one end of the spring piece 901 is connected to the square hole. The top surface of the hole is connected as a whole, and the other end thereof is in an unconstrained free state; the limiting protrusion 902 is located in the plug-in slot 8, and the other side thereof is connected as a whole with the spring sheet 901, that is, the elastic hook 9 is in an L-shaped structure, and its horizontal end protrudes into the plug-in slot 8; along the insertion direction of the cable card 1, the rear and front sides of the limiting protrusion 902 are both provided with guide surfaces 903, and the guide surfaces 903 are arranged obliquely; the plug-in board 7 is also provided with a limiting hole 10;

[0037] When in use, the plug board 7 is inserted into the plug slot 8. Since the guide surface 903 on the front side is inclined, the plug board 7 will squeeze the elastic hook 9 to bend toward the side of the avoidance slot 11. When the limiting hole 10 is directly facing the limiting protrusion 902, the pressure of the plug board 7 disappears. Under the action of its own elastic force, the limiting protrusion 902 will be re-engaged in the limiting hole 10, thereby limiting the cable card 1.

[0038] At the same time, since the rear guide surface 903 is also inclined, when the cable card 1 is pulled out, the rear guide surface 903 can guide and compress the elastic hook 9 to undergo elastic deformation, thereby reducing the difficulty of removing the cable card 1;

[0039] Reference Figure 4 , along the insertion direction of the cable card 1, the rear side of the limiting protrusion 902 is provided with a thrust surface 904, and the front side thereof is provided with a guide surface 903, the thrust surface 904 is horizontally arranged, and the guide surface 903 is inclinedly arranged; the plug board 7 is also provided with a limiting hole 10;

[0040] Since the thrust surface 904 is arranged horizontally, it will completely fit the top surface of the limiting hole 10, thereby better limiting the cable card 1 and improving the connection strength between the cable card 1 and the plug board 7;

[0041] The connecting plate 6 is also provided with an embedded screw 2, and one end of the embedded screw 2 embedded in the external structure is provided with a reinforcing component. Figure 5 , the reinforcing assembly includes at least one first limiting protrusion 3, each of which is arranged on the outer surface of the embedded screw 2. Specifically, the first limiting protrusion 3 can be a cylindrical structure, a rectangular parallelepiped structure or any structure protruding outward in the radial direction of the embedded screw; that is, the embedded screw 2 and the reinforcing pin 9 are spliced ​​in an L-shaped, T-shaped or cross-shaped structure;

[0042] The first limiting protrusion 3 is arranged to ensure that in the pulling direction of the embedded screw 2, the first limiting protrusion 3 and the external structure (such as concrete) abut against each other, so as to increase the force in the pulling direction and improve the stability of the connection;

[0043] Reference Figure 6 The reinforcing component may further include a plurality of limiting grooves 4, each of which is arranged on both sides of the embedded screw 2 along the axial direction of the embedded screw 2;

[0044] When the embedded screw 2 is embedded in the concrete component, the concrete will penetrate into the limiting groove 4, thereby fitting with the inner wall of the limiting groove in the axial direction, so as to increase the force in the direction of the pull handle and improve the stability of the connection;

[0045] Reference Figure 7 The reinforcing component includes a limit head 5, the limit head 5 is an eight-shaped structure, the closed end of the limit head 5 is integrally connected to the embedded screw 2, and the bifurcated end thereof extends to the outside of the outer peripheral surface of the embedded screw 2;

[0046] At the same time, the limit head can also be set to a diamond structure, one end of which is connected to the embedded screw 2; the protruding part of the limit head will abut against the external structure in the direction of the horn to increase the force in the direction of the handle and improve the stability of the connection;

[0047] The reinforcing assembly can effectively increase the contact area between the embedded screw 2 and the external structure, and can also form a structure that abuts against each other in the vertical direction, thereby increasing the connection strength between the embedded screw 2 and the external structure.

[0048] When the present application is used, the embedded screw is embedded in the external concrete structure, thereby achieving a stable connection between the entire isolation fixture and the external structure; at the same time, since the embedded end is provided with a reinforcement component, it can effectively improve the connection stability and reliability of the isolation fixture;

[0049] At the same time, the plug-in board can realize the quick plug-in connection between the cable card and the plug-in board, which is beneficial to improving the installation efficiency of the cable card.

[0050] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
