AI Technical Summary
The existing fence adjustment nut is loose due to the reverse rotation, which causes the door railing frame to loosen and lose its fixing function.
A baby fence equipped with an anti-loosening fixed structure is designed. By setting wedge-shaped teeth on the end surfaces of the pipe plug and the adjustment nut, the height difference between the highest point and the lowest point of the tooth surface of the wedge-shaped teeth is greater than the pitch of the screw, to prevent separation caused by the wedge-shaped effect.
It effectively prevents the pipe plug and the adjustment nut from being separated due to the wedge effect, thereby maintaining the fixed and tight fit between the pipe plug and the adjustment nut, and solving the problem of loose door frames caused by loose adjustment nuts.

Abstract
Description
Technical Field
[0001] The utility model relates to a fence, in particular to a baby fence equipped with an anti-loosening fixing structure. Background Art
[0002] A gate is a variable partition used to isolate a space, usually made of metal, plastic or wood. They are designed to provide a convenient way to limit the range of movement of infants or pets to ensure their safety and maintain order at home. The pet or child pressure gates currently on the market are all adjusted by the adjustment nuts at the four corners of the gate to adjust the pressure, thereby fixing the gate between the door frames. Since there is always a gap between the threads of the adjustment nut and the screw, it is only fixed by the friction between the nut and the screw. During the repeated shaking of the gate, the nut will slowly reverse and loosen, causing the gate pressure to decrease and eventually lose its function. Utility Model Content

The utility model prevents the pipe plug and the adjusting nut from being separated due to the wedge effect by ensuring that the height difference between the highest point and the lowest point of the tooth surface of the first end face wedge-shaped tooth and the second end face wedge-shaped tooth is greater than the pitch of the screw, thereby fixing the pipe plug and the adjusting nut tightly, and solving the problem that the adjusting nut of the existing fence may loosen due to reverse rotation, resulting in the loosening of the gate frame.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A baby fence equipped with an anti-loosening fixing structure comprises: a door frame, a door slat, a pipe plug, an adjusting nut and a screw rod.

DETAILED DESCRIPTION
[0015] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.
[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific implementation methods disclosed below.
[0017] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the implementation of the present invention, for the sake of convenience, the cross-sectional diagram showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagram is only an example, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.
[0018] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.
[0019] like Figures 1 to 5 As shown: a baby fence equipped with an anti-loosening fixing structure, comprising: a door frame 1, a door sash 2, a pipe plug 3, an adjusting nut 4, and a screw 5. The door frame 1 is movably connected with the door sash 2, the pipe plug 3 is embedded in the end surface of the door frame 1, the screw 5 is meshed with the threaded rod hole 32, and the threaded hole 42 of the adjusting nut 4 is meshed with the screw 5.
[0020] The end face of the pipe plug 3 is provided with a first end face wedge-shaped tooth 31, and the end face of the adjusting nut 4 is provided with a second end face wedge-shaped tooth 41. The first end face wedge-shaped tooth 31 and the second end face wedge-shaped tooth 41 are locked with each other. The height difference between the highest point and the lowest point of the tooth surface of the first end face wedge-shaped tooth 31 is greater than the pitch of the screw 5, and the height difference between the highest point and the lowest point of the tooth surface of the second end face wedge-shaped tooth 41 is greater than the pitch of the screw 5.
[0021] When the baby fence is shaken by external force and receives external force, due to the existence of friction between the pipe plug 3 and the adjusting nut 4, the pipe plug 3 and the adjusting nut 4 tend to separate rather than move (wedge effect), but the height difference between the highest point and the lowest point of the tooth surface of the second end face wedge-shaped tooth 41 is greater than the pitch of the screw 5, so when the pipe plug 3 and the adjusting nut 4 are separated due to the wedge effect, the first end face wedge-shaped tooth 31 and the second end face wedge-shaped tooth 41 will be stuck, so the separation process of the pipe plug 3 and the adjusting nut 4 will be interrupted. Therefore, the pipe plug and the adjusting nut are fixedly fitted and will not separate due to the wedge effect, and thus maintain a tight fit under the influence of external force.
[0022] Preferably, the gate frame 1 includes: an upper left cross bar 11, an upper right cross bar 12, a lower left cross bar 13, a lower right cross bar 14, and a vertical bar 15. The lower left cross bar 13 is connected to the lower right cross bar 14, the lower end of the vertical bar 15 on the left side of the gate frame 1 is connected to the lower left cross bar 13, the upper end of the vertical bar 15 connected to the lower left cross bar 13 is connected to the upper left cross bar 11, the lower end of the vertical bar 15 on the right side of the gate frame 1 is connected to the lower right cross bar 14, and the upper end of the vertical bar 15 connected to the lower right cross bar 14 is connected to the upper right cross bar 12.
[0023] Preferably, the left end surface of the upper left cross bar 11 is embedded with a pipe plug 3, the right end surface of the upper right cross bar 12 is embedded with a pipe plug 3, the left end surface of the lower left cross bar 13 is embedded with a pipe plug 3, and the right end surface of the lower right cross bar 14 is embedded with a pipe plug 3.
[0024] The utility model prevents the pipe plug and the adjusting nut 4 from being separated due to the wedge effect by making the height difference between the highest point and the lowest point of the tooth surface of the first end face wedge-shaped teeth 31 and the second end face wedge-shaped teeth 41 greater than the pitch of the screw 5, thereby fixing the pipe plug 3 and the adjusting nut 4 tightly, solving the problem that the adjusting nut 4 of the existing fence may loosen due to reverse rotation, resulting in the loosening of the gate frame 1.
[0025] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
