Description

Technical Field

[0001] The utility model relates to the technical field of anti-theft doors, in particular to an anti-theft door frame. Background Art

[0002] A door refers to a device installed at an entrance or exit that can be opened or closed. It is an entity that divides a limited space. Its function is to connect and close the entrances and exits of two or more spaces.

[0003] However, in the prior art, common anti-theft door frames are generally integrated structures. Such door frames occupy a large space, are not only inconvenient to transport, but are also easily deformed by collision during transportation and movement, affecting the appearance. Therefore, we propose an anti-theft door frame. Utility Model Content

[0004] The utility model provides a theft-proof door frame, which solves the above-mentioned technical problems.

[0005] The utility model solves the above-mentioned technical problems with the following solution: a kind of anti-theft door frame, comprising two first door frame plates arranged vertically, second door frame plates being arranged horizontally at the upper and lower ends of the two first door frame plates, the second door frame plates being slidably matched with the first door frame plates, a docking block movably embedded in the first door frame plates being fixedly installed on the outer side walls of the second door frame plates, an L-shaped fixing plate being fixedly installed on the inner side walls of the second door frame plates, a fixing rod movably passing through the fixing plate, the fixing rod movably passing through the first door frame plates and the second door frame plates, a fixing ring being fixedly sleeved on the outer side walls of the fixing rod, the fixing ring being fixedly connected to the fixing plate by a spring movably sleeved on the outer side walls of the fixing rod, a pulling block being fixedly installed on the end of the fixing rod.

[0006] Preferably, the contact surface between the first door frame plate and the second door frame plate is inclined at 45 degrees.

[0007] Preferably, a mounting block is fixedly mounted on the outer side wall of the first door frame plate, and a mounting hole penetrating the mounting block is formed on the outer side wall of the mounting block.

[0008] Preferably, a first closing plate is fixedly installed on the outer side wall of the first door frame plate by screws, and a second closing plate is fixedly installed on the outer side wall of the second door frame plate by screws. A docking groove is provided on the outer side wall of the second closing plate, and the docking groove fits with the first door frame plate, the second door frame plate and the docking block.

[0009] Preferably, a plurality of connection blocks are fixedly mounted on the inner side walls of the first door frame plate and the second door frame plate respectively.

[0010] The beneficial effects of the utility model are:

[0011] 1. By setting the first door frame plate and the second door frame plate, the door frame can be disassembled and reassembled, so that the door frame assembly occupies a smaller space, is convenient for transportation, reduces the collision of the door frame assembly during transportation, and is more conducive to the protection and transportation of the door frame;

[0012] 2. By setting a docking block on the outer surface of the second door frame plate, the second door frame plate can be quickly docked with the first door frame plate, and the fixing rod is used to limit and fix it, so that the installation of the second door frame plate is more stable, and at the same time, the docking of the first door frame plate and the second door frame plate is more accurate, ensuring the installation space of the door plate and the installation quality is higher. The first closing plate and the second closing plate are set for connection and reinforcement, so that the connection between the first door frame plate and the second door frame plate is closer.

[0021] The following is combined with Figure 1-4The principles and features of the present invention are described, and the examples given are only used to explain the present invention, and are not used to limit the scope of the present invention. The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer according to the following description and claims. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0022] Example 1

[0023] like Figure 1-4 As shown, the utility model is a kind of anti-theft door frame, including two first door frame plates 1 arranged vertically, and second door frame plates 2 are respectively arranged horizontally at the upper and lower ends of the two first door frame plates 1, and the outer side wall of the first door frame plate 1 is fixedly installed with a mounting block 9, and the outer side wall of the mounting block 9 is provided with a mounting hole that penetrates the mounting block, and the contact surface of the first door frame plate 1 and the second door frame plate 2 is inclined at 45 degrees, and the second door frame plate 2 is slidably matched with the first door frame plate 1, and the inner side walls of the first door frame plate 1 and the second door frame plate 2 are respectively fixedly installed with a plurality of connecting blocks 13, and the connecting blocks are provided to provide an installation basis for the installation of the first closing plate 10 and the second closing plate 11, and the outer side wall of the second door frame plate 2 is fixedly installed with a docking block 3 that is movably embedded in the first door frame plate 1, and the docking block 3 realizes the docking of the first door frame plate 1 and the second door frame plate 2, so that the second The door frame plate 2 can be installed quickly and accurately. An L-shaped fixing plate 4 is fixedly installed on the inner wall of the second door frame plate 2. A fixing rod 5 is movably penetrated through the fixing plate 4. The fixing rod 5 movably penetrates the first door frame plate 1 and the second door frame plate 2. The inner wall of the second door frame plate 2 is provided with a fixing ring 6 fixedly sleeved on the outer wall of the fixing rod 5.
