[0001] The utility model relates to the technical field of fence protection doors, in particular to an assembled protection door for fences. Background Art

[0002] As a commonly used safety protection device, fence protection doors have a wide range of applications. The main structures include door frames, door leaves, etc. In particular, door leaves are mostly a whole piece of protection panel, which is large in size, occupies more space, and is inconvenient to transport. In addition, some existing fence protection doors are directly welded, most of them are not removable or adjustable, and some are more troublesome to install, requiring the door leaves to be supported for a long time until they are aligned with the hinge holes on both sides before the installation is completed. The door leaves need to be lifted during the entire installation process, which increases the workload. Utility Model Content

[0003] 1. Technical Problems Solved

[0004] The technical problems to be solved by the utility model are that the space occupied is large, the transportation is inconvenient, the welding method cannot be disassembled or adjusted, or the installation is troublesome, the door leaf needs to be supported for a long time, and the workload is increased.

[0005] 2. Technical Solution

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is: an assembled protective door for a fence, comprising a door frame and door leaves, wherein the door leaves are multiple leaves, and the door leaves are hinged to each other through hinge seats, and sliding columns are connected to the hinge seats alternately, and sliding grooves cooperating with the sliding columns are relatively connected on the top and bottom inner walls of the door frame, and hinge holes are relatively connected on the top and bottom of one side of the door frame, and mounting seats are respectively connected at both ends of the door leaves, and a telescopically adjustable door shaft is provided in the mounting seat, and the door shaft cooperates with the hinge hole.

[0007] Furthermore, the free ends of the sliding columns are rotatably connected to rollers, and the door leaf cooperates with the sliding column and the sliding groove to facilitate the opening and folding of the door leaf. The setting of the roller makes the opening process smoother, converting the sliding of the sliding column and the sliding groove into the rolling of the roller, thereby reducing friction.

[0008] Furthermore, a driving cavity is connected to the hinge seat at the top, one end of the sliding column passes through the driving cavity and is connected to a limit plate in the driving cavity, and a spring is connected between the limit plate and the bottom end of the driving cavity. First, the top sliding column is matched with the slide groove, and the driving cavity, the limit plate and the spring are matched so that the top sliding column can be squeezed and penetrated inward into the driving cavity. The sliding column compresses the spring through the limit plate. At this time, the sliding column at the bottom end of the door leaf can be matched with the slide groove. After alignment, the door leaf is slowly lowered. Under the resetting action of the spring, the sliding columns are matched with the slide grooves respectively, and the installation is quickly completed.

[0009] Furthermore, the door shaft includes an adjusting cylinder, which is rotatably connected to the door leaf, and opposite thread grooves are respectively connected at both ends of the adjusting cylinder. A shaft rod is respectively threadedly connected at both ends of the adjusting cylinder through the thread grooves. The shaft rod slides through the mounting seat and cooperates with the hinge hole at the end. By rotating the adjusting cylinder, the adjusting cylinder drives the shaft rod through the threaded cooperation between the thread groove and the shaft rod. Since the shaft rod is slidably connected to the mounting seat, the shaft rod can only make a linear motion along the mounting seat, which facilitates the cooperation between the shaft rod and the hinge hole.

[0010] Furthermore, the outer wall of the adjusting cylinder is connected with anti-skid patterns, and the anti-skid patterns are arranged to improve the friction of the adjusting cylinder and facilitate effective driving thereof.

[0011] Furthermore, the door leaves are an even number of leaves.

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with 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 of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] Combined with Figure 1 , Figure 2 and Figure 3 , an assembled protective door for a fence, comprising a door frame 1 and a door leaf 2, characterized in that: the door leaf 2 is a plurality of leaves, the door leaf 2 is an even number of leaves, the door leaves 2 are hinged to each other through a hinge seat 14, and a sliding column 3 is connected to the hinge seat 14 at intervals, and a sliding groove 4 cooperating with the sliding column 3 is relatively connected on the top and bottom inner walls of the door frame 1, and a hinge hole 5 is relatively connected to the top and bottom of one side of the door frame 1, and the end of the door leaf 2 is respectively connected with a mounting seat 6, and a telescopically adjustable door shaft 7 is arranged in the mounting seat 6, and the door shaft 7 cooperates with the hinge hole 5. The door shaft 7 includes an adjusting cylinder 12, and the outer wall of the adjusting cylinder 12 is connected with anti-slip grooves, and the adjusting cylinder 12 is rotatably connected to the door leaf 2, and opposite thread grooves are respectively connected at both ends of the adjusting cylinder 12, and shaft rods 13 are respectively threadedly connected at both ends of the adjusting cylinder 12 through the thread grooves, and the shaft rod 13 slides through the mounting seat 6 and cooperates with the hinge hole 5 at the end.

[0024] The hinged arrangement of several door leaves 2 in the above structure facilitates the folding of the door leaves 2, reduces the occupied space, and facilitates transportation. After the door leaves 2 are opened, they are in a folded state and do not occupy too much space. The door leaves 2 cooperate with the slide column 3 and the slide groove 4 to facilitate the opening and folding of the door leaves 2. The arrangement of the roller 8 makes the opening process smoother, converting the sliding of the slide column 3 and the slide groove 4 into the rolling of the roller 8 to reduce friction. The coordinated arrangement of the hinge hole 5, the mounting seat 6 and the door shaft 7 facilitates the coordinated installation of the door leaf 2 and the door frame 1.

[0025] Embodiment 2

[0026] Based on the first embodiment, combined with the attached Figure 4 The free ends of the slide column 3 are rotatably connected with rollers 8, and the top hinge seat 14 is connected with a driving cavity 9. One end of the slide column 3 passes through the driving cavity 9 and is connected with a limit plate 10 in the driving cavity 9. A spring 11 is connected between the limit plate 10 and the bottom end of the driving cavity 9.

[0027] The coordinated arrangement of the slide column 3, roller 8, drive cavity 9, limit plate 10 and spring 11 in the above structure facilitates quick connection of the door leaf 2 and the door frame 1, thereby improving installation efficiency; and can also reduce friction and extend the service life of the door leaf 2.

[0028] The specific usage is as follows:

[0029] First, the top slide post 3 is matched with the slide groove 4. Through the matching arrangement of the driving cavity 9, the limit plate 10 and the spring 11, the top slide post 3 is forced to be squeezed and can penetrate inward into the driving cavity 9. The slide post 3 compresses the spring 11 through the limit plate 10. At this time, the slide post 3 at the bottom end of the door leaf 2 can be matched with the slide groove 4. After alignment, the door leaf 2 is slowly lowered. Under the reset action of the spring 11, the slide post 3 is respectively matched with the slide groove 4, thereby quickly completing the installation;

[0030] By rotating the adjusting cylinder 12, the friction of the adjusting cylinder 12 can be increased by setting the anti-slip pattern, so that it can be effectively driven. The adjusting cylinder 12 drives the shaft 13 through the threaded cooperation between the threaded groove and the shaft 13. Since the shaft 13 is slidably connected to the mounting seat 6, the shaft 13 can only move in a straight line along the mounting seat 6, which makes it easier for the shaft 13 to cooperate with the hinge hole 5, thereby improving the assembly efficiency.
