DETAILED DESCRIPTION

[0020] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0021] like Figure 1 and Figure 2As shown, a gate with adjustable width includes a gate frame 100 fixed to a door frame, two sides of the gate frame 100 are fixedly connected to the door frame on the corresponding side, and the gate frame 100 is used to install a gate body 200. The gate body 200 swings forward and backward relative to the gate frame 100 to achieve the opening and closing of the gate body 200. The forward and backward swinging direction here is the opening and closing direction of the gate body 200. Preferably, the gate frame 100 is composed of a square tube, which has high stability, light weight, and is easy to transport and install.

[0022] The gate frame 100 includes a first connecting rod 110 and two parallel second connecting rods 120 vertically connected to the first connecting rod 110. The gate body 200 has a hinged side 210 and a free side 220 opposite to the hinged side. The bottom of the hinged side 210 is hinged to the first connecting rod 110, and the top of the hinged side 210 is hinged to the second connecting rod 120 on one side, so as to realize the connection between the gate body 200 and the gate frame 100. Preferably, the hinged mode is to use a rotating shaft connection. The gate body 200 is rectangular. Preferably, the gate body 100 is a fence type, which can not only block pets, but also observe the situation of pets, and can also feed without disassembling the gate body 100.

[0023] A lock tongue 221 is provided at the top of the free side 220, and a lock hole 121 matching the lock tongue 221 is provided at the second connecting rod 120 on the corresponding side. The lock tongue 221 is inserted into the lock hole 121 to achieve relative locking of the gate fence body 200 and the gate fence frame 100, thereby preventing the gate fence body 200 from being easily pushed open. Preferably, the lock tongue 221 is telescopic and has a toggle switch 222. The toggle switch 222 controls the telescopic movement of the lock tongue 221. When the toggle switch 222 is toggled toward the second connecting rod 120 on the side with the lock hole 121, the lock tongue 221 is inserted into the lock hole 121 to fix the gate fence body 200; when the toggle switch 222 is toggled toward the second connecting rod 120 on the side without the lock hole 222, the lock tongue 221 withdraws from the lock hole 121 to open the gate fence body 200.

[0024] In this embodiment, if Figure 3 and Figure 4As shown, a parallel hollow sleeve 300 is arranged on the side of the second connecting rod 120 on one side facing the door frame, and the hollow sleeve 300 located below is in contact with the horizontal plane to ensure the stability of the hollow sleeve 300. An extension column 400 is arranged in the hollow sleeve 300, and the end face of the extension column 400 facing outward is fixedly connected to the door frame on the corresponding side. The extension column 400 can be pulled out in the hollow sleeve 300. The shorter the contact length between the extension column 400 and the hollow sleeve 300, the longer the length of the extension column 400 extending out of the hollow sleeve 300, which is suitable for occasions where the distance between door frames is large. The length of the extension column 400 extending from the hollow sleeve 300 is adjusted according to the width of the door frame. After adjusting to a suitable distance, the end face of the extension column 400 is fixed to the corresponding door frame to achieve the installation of the door rail.

[0025] If the door rail width does not need to be adjusted, the extension column 400 is retracted into the hollow sleeve 300, and the end surface fixed to the door frame is located at the open end of the hollow sleeve 300, thereby achieving a fixed connection with the door frame.

[0026] In this embodiment, parallel hollow sleeves 300 are provided on the side of the two second connecting rods 120 facing the door frame, and the hollow sleeve 300 located at the bottom is in contact with the horizontal plane to ensure the stability of the hollow sleeve 300. An extension column 400 is provided in the hollow sleeve 300, and the end face of the extension column 400 facing outward is fixedly connected to the door frame on the corresponding side. The extension column 400 can be pulled out in the hollow sleeve 300. The shorter the contact length between the extension column 400 and the hollow sleeve 300, the longer the length of the extension column 400 extending out of the hollow sleeve 300, which is suitable for occasions with large door frame spacing. The length of the extension column 400 extending from the hollow sleeve 300 is adjusted according to the width of the door frame. After adjusting to a suitable distance, the end face of the extension column 400 is fixed to the corresponding door frame to achieve the installation of the door rail.

[0027] In this embodiment, if Figure 4 As shown, in order to improve the locking degree between the extension column 400 and the hollow sleeve 300 and prevent the extension column 400 from automatically retracting, an anti-slip tooth 410 is provided on the surface of the extension column 400, and a groove that cooperates with the anti-slip tooth 410 is provided in the hollow sleeve 300. After the extension column 400 is pulled out to an appropriate length, the anti-slip tooth 410 cooperates with the groove to achieve the locking of the extension column 400 and the hollow sleeve 300. Preferably, the anti-slip tooth 410 is a wedge-shaped tooth with a plurality of teeth, which is axially arranged along the outer circumference of the extension column 400 to improve the anti-slip effect between the extension column 400 and the inner wall of the hollow sleeve 300. Without the action of external force, the extension column 400 will not change position relative to the hollow sleeve 300. Preferably, there are four groups of anti-slip teeth 410, which are evenly distributed on the periphery of the extension column 400. This can not only achieve multi-directional anti-slip of the extension column 400, but also reduce the processing area of ​​the anti-slip teeth 410 and reduce the processing difficulty compared to setting the anti-slip teeth 410 on the entire periphery of the extension column 400.

[0028] In this embodiment, an auxiliary tube 500 is disposed between two hollow sleeves 300 on the same side to provide support for the two hollow sleeves 300 and reduce the breakage rate of the hollow sleeves 300 .

[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected.
