DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4 , an anti-theft door bracket with an anti-theft lock, including an anti-theft door body installed in a reserved hole of a building structure, the anti-theft door bracket includes a frame 1, a door body 2, and an anti-theft lock body 3. The specific model and specification of the anti-theft lock body 3 needs to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated;

[0022] A through hole 4 and a placement groove 5 are provided in the frame 1. A guide rod 6 is fixedly installed in the through hole 4, and a symmetrically arranged guide block 7 is slidably sleeved on the guide rod 6. The guide rod 6 guides the guide block 7, so that the guide block 7 can smoothly pull the connecting rod 12 when moving.

[0023] The guide rod 6 is horizontally arranged at both ends of the frame 1, and a fixing bolt is arranged between the two corresponding guide blocks 7. The limit frame 11 and the connecting rod 12 extend to one end outside the frame 1, and the two ends of the connecting rod 12 are respectively connected with the guide block 7 and the middle end pin of the limit frame 11. By applying pressure to the two clamping blocks 8, the two guide blocks 7 drive the connecting rod 12 to deflect when moving toward each other. When deflecting, the connecting rod 12 presses the limit frame 11 into the reserved opening in the building structure. By arranging the two limit frames 11 at both ends of the frame 1, the contact degree between the limit frames 11, the frame 1 and the building structure is increased.

[0024] A clamping block 8 is fixedly mounted on the guide block 7, a sealing plate 9 is placed in the placement groove 5, and a limiting groove 10 for limiting the clamping block 8 is provided on the sealing plate 9, and a limiting bolt corresponding to the frame 1 is threadedly connected on the sealing plate 9, and the clamping block 8 can be clamped through the limiting groove 10 on the sealing plate 9, thereby locking the position of the limiting frame 11;

[0025] A limit frame 11 extending into the reserved opening of the building structure is provided in the sliding sleeve in the through hole 4, and a connecting rod 12 is connected between the limit frame 11 and the two guide blocks 7, and a positioning column 14 extending into the building structure is connected to the limit frame 11 through a connecting piece;

[0026] The connecting member includes a moving rod 13 slidably sleeved in the limiting frame 11, and a positioning column 14 is arranged on the moving rod 13, a spring 15 is welded between the moving rod 13 and the limiting frame 11, a rotating rod 17 is rotatably installed in the limiting frame 11, and a limiting block 18 corresponding to the moving rod 13 is fixedly installed on the rotating rod 17, and the spring 15 realizes the reset function of the moving rod 13. When the moving rod 13 is in an unloaded state, the moving rod 13 can drive the positioning column 14 to extend out of the limiting frame 11;

[0027] The positioning column 14 and the moving rod 13 extend to the two sides outside the limit frame 11, and the spring 15 is horizontally welded to the moving rod 13 extending to the one side inside the limit frame 11, the rotating rod 17 is horizontally arranged, and the moving rod 13 is provided with two positioning grooves 16 for positioning the limit block 18;

[0028] A connecting plate 19 is placed on the limit frame 11, and a sleeve 20 for clamping the upper end of the limit block 18 is integrally connected to the connecting plate 19, and a locking bolt corresponding to the limit frame 11 is threadedly connected to the connecting plate 19;

[0029] When the limit block 18 is disconnected from the positioning groove 16, the positioning column 14 extends into the building structure under the action of the spring 15, and the limit block 18 is driven to extend into another positioning groove 16 through the rotation of the rotating rod 17, so that the position of the moving rod 13 and the positioning column 14 can be locked. By extending the limit frame 11 into the reserved opening in the building structure and extending the positioning column 14 into the building structure, the contact degree between the frame 1 and the building structure is increased, so that the frame 1 has a certain stability and protection as a whole after assembly.

[0030] The functional principle of the utility model can be explained through the following operation modes:

[0031] When the anti-theft door body needs to be installed;

[0032] First, a reserved hole for placing the frame 1 is opened on the building structure, and a reserved opening is chiseled out on the reserved hole;

[0033] Installing the frame 1 in the building structure;

[0034] Manually apply pressure to the two blocks 8, so that the two blocks 8 move toward each other and drive the guide block 7 to slide on the guide rod 6. When the guide block 7 moves, the connecting rod 12 is deflected, so that when the connecting rod 12 moves in the through hole 4, it drives the limit frame 11 to move downward and extend into the reserved opening;

[0035] Use a fixing bolt to connect the two guide blocks 7, manually pull the rotating rod 17, so that the rotating rod 17 drives the limit block 18 to rotate and disconnect from one of the positioning grooves 16, and under the action of the spring 15, the spring 15 drives the moving rod 13 and the positioning column 14 to extend outward, so that the positioning column 14 can extend into the building structure;

[0036] Continue to pull the rotating rod 17 to rotate, the rotating rod 17 drives the limit block 18 to extend into another positioning groove 16, install the connecting plate 19 on the limit frame 11, make the connecting plate 19 drive the sleeve 20 to clamp the upper end of the limit block 18, and use the locking bolt to connect the connecting plate 19 and the limit frame 11;

[0037] Place the sealing plate 9 in the placement groove 5. The limiting groove 10 on the sealing plate 9 can clamp the clamping block 8. Use the limiting bolt to connect the sealing plate 9 and the frame 1. Then install the door body 2 on the frame 1, and install the anti-theft lock body 3 on the door body 2.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
