[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 combined anti-theft door cover, including two first door covers 1 arranged vertically, the outer side walls of the first door cover 1 and the second door cover 2 are respectively provided with door panel grooves, and the door panel grooves are provided to facilitate the closing of the door panels, and the second door cover 2 is slidably matched between the upper ends of the two first door covers 1, and the cross-sections of the first door cover 1 and the second door cover 2 are both L-shaped, the outer side wall of the first door cover 1 is slidably matched with a first fixing plate 3, and the outer side wall of the second door cover 2 is slidably matched with a second fixing plate 4, and the outer side wall of the second fixing plate 4 is fixedly installed with a semi-cylindrical splicing block 12, the splicing block 1 is movably embedded in the first fixing plate 3, and the splicing block 12 is provided to enhance the connection between the first fixing plate 3 and the second fixing plate 4, thereby improving the overall strength of the device, and the outer side walls of the first fixing plate 3 and the second fixing plate 4 are respectively fixedly installed with hollow A connecting rod 5, the inner wall of the connecting rod 5 is fixedly installed with two symmetrically arranged slide rails 6, the two slide rails 6 are fixedly connected by a vertically arranged connecting piece 7, and the side walls on both sides of the connecting piece 7 are respectively installed with a clamping block 8 through an elastic mechanism, the clamping block 8 is slidably connected to the slide rail 6, the clamping block 8 is wedge-shaped, and the clamping block 8 movably passes through the connecting rod 5, and the outer side walls of the first door frame 1 and the second door frame 2 are respectively provided with a clamping groove that matches the connecting rod 5 and the clamping block 8. A plurality of connecting grooves 11 are provided on the surface of the first door frame 1, and the plurality of connecting grooves 11 are arranged at equal intervals. The connecting grooves 11 cooperate with the mounting blocks on the wall to assist in limiting fixation and make the fixation more stable. By arranging the first door frame 1 and the second door frame 2 that can be spliced, the device not only makes the device more convenient to carry, but also makes the installation of the door frame more convenient.
[0024] Example 2
[0025] like Figure 1-4As shown, the elastic mechanism includes a telescopic rod 9 which is laterally fixedly installed on the outer wall of the connecting piece 7. The telescopic rod 9 is fixedly connected to the clamping block 8. A spring 10 is movably sleeved on the outer wall of the telescopic rod 9. The telescopic rod 9 provides an installation basis for the spring 10. The spring 10 pushes the clamping block 8 to move outward to ensure the clamping of the clamping block 8 with the inside of the clamping slot, thereby realizing the connection and fixation between the first door cover 1 and the first fixed plate 3, or the connection and fixation between the second door cover 2 and the second fixed plate 4, thereby improving the integrity of the device. The clamping block 8 is wedge-shaped and is irreversible in one direction, thereby preventing the first fixed plate 3 or the second fixed plate 4 from being loosened during installation, and having higher strength.
[0026] Working principle:
[0027] When in use, first install the first door frame 1 on both sides of the door opening and fix it with foam glue, then insert the second door frame 2 into the top of the door opening and fix it with foam glue, and then align the first fixing plate 3 with the first door frame 1, and insert the connecting rod 5 on the first fixing plate 3 into the slot on the first door frame 1. The inner wall of the slot squeezes the clamping block 8 to overcome the force of the spring 10 and move inward until the first fixing plate 3 is fitted with the first door frame 1. The clamping block 8 loses external force and moves outward to engage under the push of the spring 10. Repeat this operation to install the second fixing plate 4, and fix it with foam glue to complete the installation.
