[0021] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings show typical embodiments of this utility model.

[0022] Example 1:

[0023] like Figures 1-5 As shown, the present invention provides a retractable gate, including a support assembly 1 and a telescopic assembly 2. The support assembly 1 includes a support frame 101, a main mounting plate 102 on the left side of the support frame 101, and a support rod 103 at the front end of the main mounting plate 102. The telescopic assembly 2 includes a sliding frame 201, which is located at the front end of the support frame 101. A secondary mounting plate 203 is provided on the right side of the sliding frame 201, and a main magnetic suction piece 204 is fixedly connected to the front end of the secondary mounting plate 203.

[0024] like Figures 1-5 As shown, the support frame 101 has sliding grooves 108 on both the upper and lower sides of the front end, and sliding blocks 109 are fixedly connected to both the upper and lower sides of the rear end of the sliding frame 201. The sliding blocks 109 are slidably connected in the sliding grooves 108.

[0025] like Figures 1-5 As shown, multiple sets of railings 202 are fixedly connected to the inner ends of both the support frame 101 and the sliding frame 201, and a sliding plate 207 is fixedly connected to the top left side of the sliding frame 201.

[0026] like Figures 1-5 As shown, the top of the sliding plate 207 is threaded with a fastening bolt 106, and the top of the support frame 101 has multiple sets of threaded holes 107, all of which are threaded to the threaded holes 107.

[0027] In practice, by rotating the fastening bolt 106 to separate it from the threaded hole 107, the position of the sliding bracket 201 can be adjusted laterally, thus adapting to openings of different widths for installation and use. The overall structure is simple and easy to use, and has good practicality.

[0028] Example 2:

[0029] like Figures 1-5As shown, on the basis of the embodiment one, the utility model provides a kind of scalable door bar technical scheme: connecting sleeve 105 is sleeved on support rod 103, torsion spring 104 is sleeved on support rod 103, torsion spring 104 top end is fixedly connected in support rod 103 top, and torsion spring 104 bottom end is fixedly connected in connecting sleeve 105.

[0030] As Figures 1-5 As shown, the right end of sliding frame 201 is fixedly connected with a secondary magnetic suction piece 205, and the rear end of the secondary magnetic suction piece 205 is magnetically connected with the front end of the primary magnetic suction piece 204.

[0031] As Figures 1-5 As shown, the front end of the secondary mounting plate 203 is rotatably connected with a magnetic suction strip 206, and the rear end of the magnetic suction strip 206 is magnetically connected with the front end of the secondary magnetic suction piece 205.

[0032] In the implementation, through the cooperation of the support assembly 1 and the telescopic assembly 2, the cooperation of the torsion spring 104 and the connecting sleeve 105 can automatically reset and close after the door bar is opened, the cooperation of the primary magnetic suction piece 204 and the secondary magnetic suction piece 205 can limit the door bar without affecting the opening and closing of the door bar, and the rotation of the magnetic suction strip 206 can completely lock the door bar so that it cannot be pushed open, which improves the use convenience and ensures the safety protection ability for children and materials.

[0033] The technical solution has the following advantages in practical application, including but not limited to the following points:

[0034] 1. By rotating the fastening bolt 106 to separate it from the threaded hole 107, the position of the sliding frame 201 can be adjusted horizontally, so that it can be installed and used for openings of different widths, and the overall structure is simple and convenient to use, with good practicality.

[0035] 2. By the cooperation of the torsion spring 104 and the connecting sleeve 105, the door bar can be automatically reset and closed after being opened, the cooperation of the primary magnetic suction piece 204 and the secondary magnetic suction piece 205 can limit the door bar without affecting the opening and closing of the door bar, and the rotation of the magnetic suction strip 206 can completely lock the door bar so that it cannot be pushed open, which improves the use convenience and ensures the safety protection ability for children and materials.

[0036] The technical scheme is fixedly installed on the support frame 201 through the main mounting plate 102, then the fastening bolt 106 is separated from the threaded hole 107, at this time the sliding block 109 and the sliding groove 108 are directly pushed to the appropriate position through the sliding block 109 and the sliding groove 108, then the fastening bolt 106 is rotated to limit and fix the sliding frame 201, at this time the secondary mounting plate 203 is installed on the right side of the sliding frame 201 in the appropriate position, when the person pushes the door bar, the support frame 101 drives the connecting sleeve 105 to rotate, so that the torsional spring 104 is deformed, when the door bar is no longer stressed, the torsional spring 104 is reset to drive the door bar to rotate and close as a whole, at this time the right end of the sliding frame 201 is driven to contact and magnetically attract the main magnetic attraction piece 204, the magnetic attraction strip 206 is rotated to be magnetically attracted to the secondary magnetic attraction piece 205, so that the door bar can be completely fixed and cannot be pushed.

[0037] The above is only an exemplary embodiment of the present disclosure, which cannot limit the scope of the present disclosure. That is, any equivalent changes and modifications made according to the teachings of the present disclosure are still within the scope of the present disclosure.
