DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0019] Embodiment: as Figures 1-6 The utility model provides a fireproof door door frame, including door frame body 1, door frame body 1 includes two vertical frames 11, two first horizontal frames 12, second horizontal frame 13, second horizontal frame 13 is located between two first horizontal frames 12, both sides of two vertical frames 11 are fixedly installed with two first fixed plates 14, two second fixed plates 15, two first fixed plates 14, two second fixed plates 15 are located at the edge of vertical frame 11, and every same side two first fixed plates 14 are located at the top and bottom of vertical frame 11 respectively, and every same side two second fixed plates 15 are located between two first fixed plates 14, and every vertical frame 11 is provided with the connecting plate 16 corresponding with parallel to its side near second fixed plate 15, and two first bolt holes 17 that are symmetrically distributed are passed through and set up on the connecting plate 16,

[0020] The side of connecting plate 16 near second fixed plate 15 is fixedly installed with cylinder 2, and cylinder 2 is located at the edge of connecting plate 16, and the middle part of cylinder 2 is threadedly connected with threaded rod 21, one side of threaded rod 21 away from cylinder 2 is fixedly installed with compression plate 22, and the side of compression plate 22 away from threaded rod 21 is fixedly installed with rhombus block 23, the middle part of second fixed plate 15 is passed through and set up with square groove 25, and the middle part of first fixed plate 14 is passed through and set up with second bolt hole 26.

[0021] The side of connecting plate 16 near second fixed plate 15 is fixedly installed with cylinder 2, and cylinder 2 is located at the edge of connecting plate 16, and the middle part of cylinder 2 is threadedly connected with threaded rod 21, one side of threaded rod 21 away from cylinder 2 is fixedly installed with compression plate 22, and the side of compression plate 22 away from threaded rod 21 is fixedly installed with rhombus block 23, the middle part of second fixed plate 15 is passed through and set up with square groove 25, and the middle part of first fixed plate 14 is passed through and set up with second bolt hole 26.

[0022] The middle part of the card plate 3 is provided with a first screw hole 4, and the bottom end of the first horizontal frame 12 is provided with a second screw hole 41 at the position of the card slot 31, which is matched with the first screw hole 4. By arranging the first screw hole 4 and the second screw hole 41, the first horizontal frame 12 and the card plate 3 are further fixed, and the stability between the first horizontal frame 12 and the second horizontal frame 13 is increased.

[0023] The diameter of the cylinder 2 is smaller than the height of the square groove 25, and the length of the cylinder 2 is smaller than the width of the second fixed plate 15, so that the cylinder 2 does not affect the fitting of the second fixed plate 15 when the second fixed plate 15 is fitted with the connecting plate 16, thereby affecting the installation of the door frame body 1.

[0024] The length and height of the square groove 25 are slightly longer than those of the transverse pressing plate 22, which is more convenient for the pressing plate 22 to pass through the square groove 25, and improves the installation efficiency of the door frame body 1.

[0025] The outer part of the threaded rod 21 is fixedly provided with a fixed block 5, the side close to the cylinder 2 of the fixed block 5 is fixedly provided with a connecting rod 51, and the cylinder 2 is provided with an arc-shaped groove 52 matched with the connecting rod 51. By arranging the connecting rod 51 and the arc-shaped groove 52, when the threaded rod 21 rotates, the fixed block 5 and the connecting rod 51 rotate in the arc-shaped groove 52. Under the action of the threaded rod 21, the connecting rod 51 slowly moves the connecting plate 16 in the opposite direction in the arc-shaped groove 52. Then, when the connecting rod 51 slides from one side of the arc-shaped groove 52 to the other side, it indicates that the pressing plate 22 rotates 90 degrees, and the pressing plate 22 changes from vertical to horizontal and corresponds to the square groove 25. The pressing plate 22 and the diamond block 23 can pass through the square groove 25, so that it is more clear to know that the pressing plate 22 corresponds to the square groove 25 when the diamond block 23 is rotated to a certain position, and the installation efficiency of the door frame body 1 is further improved.

[0026] The vertical frame 11 and the second horizontal frame 13 are connected by bolts, which facilitates the assembly of the vertical frame 11 and the second horizontal frame 13.

[0027] Working principle: when the door frame body 1 is assembled and assembled with the wall, first measure the installation position of the connecting plate 16 at the position where the door frame body 1 is installed, and drill holes at the corresponding position. After the holes are drilled, insert the bolts into the first bolt holes 17 on the connecting plate 16 and the corresponding holes in the wall, and then fix them. After the connecting plate 16 is fixed with the wall, one of the vertical frames 11 is assembled with one of the first horizontal frames 12 by bolts. Similarly, the other vertical frame 11 is assembled with the other first horizontal frame 12. After assembly, the vertical frame 11 with the first horizontal frame 12 is installed on the corresponding side of the door hole.

[0028] When installing, the second fixing plate 15 on the vertical frame 11 is corresponded with the connecting compression plate 22, the compression plate 22 and the diamond block 23 are passed through the square slot 25 on the second fixing plate 15, the second fixing plate 15 is adhered with the connecting plate 16, then the diamond block 23 is rotated to drive the compression plate 22 and the threaded rod 21 to rotate, the threaded connection between the threaded rod 21 and the cylinder 2 makes the compression plate 22 move to the direction of the second fixing plate 15, when the compression plate 22 is completely inserted into the cylinder 2, the compression plate 22 is just adhered with the second fixing plate 15 and the compression plate 22 and the second fixing plate 15 are in cross shape, thereby the vertical frame 11 with the first horizontal frame 12 is preliminarily installed on one side of the door hole, and the vertical frame 11 with the first horizontal frame 12 is installed on the other side of the door hole by the same way;

[0029] When the two vertical frames 11 with the first horizontal frame 12 are preliminarily installed, the bolt is inserted into the second bolt hole 26 on the first fixing plate 14 to reinforce, then the clamping plate 3 on the second horizontal frame 13 is clamped into the clamping slot 31 on the first horizontal frame 12, then the reinforcement is carried out by the screw.

[0030] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application belong to the scope of the claims of the present application and the equivalent technologies, the present application also intends to include these modifications and variations.
