Description

Technical Field

[0001] This utility model relates to the field of fence technology, and more specifically to a fence gate locking structure. Background Technology

[0002] Children's fences, also known as playpens, safety fences, or play fences, primarily serve to provide a safe and comfortable environment for children. Allowing children to move and play freely within the fenced area helps develop their physical coordination.

[0003] For easy access, fences are usually equipped with gates. When children are playing, the gates need to be closed and locked to prevent them from leaving the safe activity space defined by the fence. Currently, the existing gate locking mechanisms only use simple latches or buckles. Although this method is convenient for locking and unlocking, children may unlock the gate by pulling or flipping the bolt out of curiosity, causing the gate to open. At this time, the child may leave the safe area of ​​the fence, causing unnecessary danger. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fence gate locking structure that offers high security and effectively prevents children from opening the locking structure while playing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fence gate locking structure, comprising a fence frame and a gate body, wherein one end of the gate body is hinged to the fence frame, and a locking structure is provided between the other end of the gate body and the fence frame, the locking structure comprising a rotating handle and a limiting plate, the rotating handle being movably disposed on the fence frame, and the limiting plate being protruding from the fence frame on the side corresponding to the gate body; the rotating handle is rotated toward the gate body, so that the gate body is clamped and locked between the rotating handle and the limiting plate.

[0006] The present invention is further configured such that: the rotating handle is provided with a connecting shaft, the fence frame is provided with a connecting hole, and the connecting shaft is inserted into the connecting hole.

[0007] The present invention is further configured such that: a spring groove is provided on one side of the connecting hole, a baffle is provided at the end of the connecting shaft, and a spring is provided between the spring groove and the baffle.

[0008] The present invention is further configured such that the rotating handle is provided with a protruding gripping part.

[0009] The present invention is further configured such that: a first limiting protrusion is provided on the door body, and when the rotating handle is rotated toward the door body, the rotating handle cooperates with the first limiting protrusion to achieve the positioning of the rotating handle.

[0010] The present invention is further configured such that: a positioning cavity is provided on the rotating handle, and the side wall of the positioning cavity corresponding to the first limiting protrusion is provided with an inclined surface with an inclined structure on the outside. When the rotating handle is rotated toward the door, the first limiting protrusion abuts against the upper part of the inclined surface and enters the positioning cavity along the inclined surface.

[0011] The present invention is further configured such that: a second limiting protrusion is provided on the fence frame, and a notch is provided on the side wall of the positioning cavity corresponding to the second limiting protrusion; when the rotating handle is rotated toward the fence frame, the second limiting protrusion enters the positioning cavity through the notch.

[0012] The present invention is further configured such that: the limiting plate is provided with a positioning groove, and the door body is provided with a protrusion, and the positioning groove cooperates with the protrusion.

[0013] The present invention is further configured such that: the fence frame and the gate body are provided with fan-shaped grooves for rotating the rotating handle and for constraining the rotation stroke of the rotating handle.

[0014] In summary, this utility model has the following beneficial effects:

[0015] Compared to existing technologies, this invention utilizes a rotating handle that achieves axial extension and rotation through the cooperation of a connecting hole and a connecting shaft. Simultaneously, a spring keeps the rotating handle pressed against the fence frame. When locking, the rotating handle rotates, causing the first limiting protrusion to abut against the inclined surface and push the handle up along the inclined surface, ultimately allowing the first limiting protrusion to enter the positioning cavity. Since only the outer side of the inclined surface is inclined, the rotating handle cannot rotate towards the fence frame, thus locking the gate. When unlocking, the axial extension and retraction of the rotating handle allows it to be pulled up axially, causing the first limiting protrusion to leave the positioning cavity. Then, while still pulled up, rotating the handle towards the fence frame releases the handle from the gate, unlocking it. Therefore, this invention requires only one action—rotating the handle towards the gate—for locking, maintaining a quick and easy locking operation. Unlocking requires first pulling up the rotating handle before rotating it towards the fence frame, employing two separate actions, greatly reducing the possibility of children unlocking the gate while playing and improving its safety.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] This embodiment discloses a fence gate locking structure, such as Figure 1-3 As shown, the enclosure includes a fence frame 1 and a door 2. One end of the door 2 is hinged to the fence frame 1, and a locking structure 3 is provided between the other end of the door 2 and the fence frame 1. The locking structure 3 includes a rotating handle 31 and a limiting plate 32. The rotating handle 31 is movably mounted on the fence frame 1, and the limiting plate 32 protrudes from the fence frame 1 on the side corresponding to the door 2. The rotating handle 31 and the limiting plate 32 are arranged opposite to each other, and the distance between them is exactly equal to the thickness of the door 2. Thus, when the door 2 is closed, the rotating handle 31 rotates to one side of the door 2, so that the door 2 is clamped and locked between the rotating handle 31 and the limiting plate 32.

[0025] Furthermore, refer to Figure 4-6 The rotating handle 31 is equipped with a connecting shaft 311, and the fence frame 1 is equipped with a connecting hole 11. The connecting shaft 311 is inserted into the connecting hole 11. This structure allows the rotating handle 31 to rotate and move axially within the connecting hole 11. Furthermore, a spring groove 111 is provided on one side of the connecting hole 11, and a baffle 4 is provided at the end of the connecting shaft 311. A spring 5 is abutted between the spring groove 111 and the baffle 4. See details... Figure 5 , Figure 5 The left side shows the normal state with spring 5 extended. Spring 5 opens the gap between the baffle 4 and the bottom of the spring cavity 111. Since the baffle 4 can be fixed to the end of the connecting shaft 311 with screws or the like, spring 5 presses the rotating handle 31 against the surface of the fence frame 1. Figure 5 The right side shows the state when the rotating handle 31 is manually pulled up. At this time, the spring 5 is compressed, and the rotating handle 31 leaves the surface of the fence frame 1. When the handle is released, the spring 5 releases its elasticity, and the rotating handle 31 returns to its original position. Figure 5 The left side view. This allows the rotating handle 31 to rotate and extend axially, facilitating subsequent engagement with the first limiting protrusion 61.

[0026] Furthermore, to facilitate manual operation of the rotating handle 31 during the pulling action, a protruding grip portion 312 is provided on the rotating handle 31. In this embodiment, see... Figure 1-3 The grip 312 is configured as a raised ridge on the rotating handle 31. When operating, the user holds the handle on both sides of the ridge, which can effectively pull up the rotating handle 31 and drive it to rotate.

[0027] Furthermore, a first limiting protrusion 61 is provided on the door body 2. When the rotating handle 31 rotates towards the door body 2, the rotating handle 31 cooperates with the first limiting protrusion 61 to achieve the positioning of the rotating handle 31. For a specific embodiment of the structure, please refer to [reference needed]. Figure 6 A positioning cavity 7 is provided on the rotating handle 31. The side wall of the positioning cavity 7, corresponding to the first limiting protrusion 61, has an inclined surface 71 with an inclined outer side. When the rotating handle 31 rotates towards the door 2, the first limiting protrusion 61 abuts against the inclined surface 71. As the rotation continues, the rotating handle 31 is pushed upwards along the inclined surface, and then the first limiting protrusion 61 enters the positioning cavity 7. After entering the positioning cavity 7, the spring 5 drives the rotating handle 31 to return to its original position. Thus, when the rotating handle 31 wants to rotate in the opposite direction, it will be blocked by the vertical inner wall of the inclined surface 71, thereby keeping the rotating handle 31 in a fixed position. Figure 3 In this state, simply rotating the handle 31 is insufficient to unlock the device. Unlocking requires manually pulling the handle 31 upwards, causing the first limiting protrusion 61 to disengage directly from the positioning cavity 7. This ensures that when the handle 31 is rotated again, the first limiting protrusion 61 will not obstruct the vertical inner wall of the inclined surface 71, allowing the handle to rotate smoothly. Figure 1 In this state, the door 2 can be opened normally. Therefore, in this embodiment, after the rotating handle 31 is turned to one side of the door to lock, unlocking requires pulling up the rotating handle 31 while simultaneously rotating it. That is, two consecutive actions are required to unlock, which greatly improves the security of the lock structure and prevents children from unlocking the lock structure due to curiosity while playing.

[0028] Furthermore, a second limiting protrusion 62 is provided on the fence frame 1. The positioning cavity 7 can also have a beveled structure on the side wall corresponding to the second limiting protrusion 62, making the positioning more accurate. However, for ease of locking, in this embodiment, a notch 72 is provided on the side wall of the positioning cavity 7 corresponding to the second limiting protrusion 62. When the rotating handle 31 is rotated toward the fence frame 1, the second limiting protrusion 62 enters the positioning cavity 7 through the notch 72. The notch can be set slightly smaller than the second limiting protrusion 62, so that when the rotating handle 31 is rotated, there is a slight jolt between the notch 72 and the second limiting protrusion 62, improving the feel of rotation and also playing a certain positioning role. Of course, due to the action of the spring 5, the lower surface of the rotating handle 31 will always be in contact with the surface of the fence frame, so the friction force when the rotating handle 31 is rotated is relatively large. The notch 72 may not play a limiting role, but only allow the second limiting protrusion 62 to pass through. The above embodiments are all for the purpose of ensuring ease of operation when rotating toward one side of the door body 2. Specifically, when locking, simply hold the grip 312 and rotate the handle 31 toward the door 2. This embodiment ensures that locking is simple and convenient, while improving security when unlocking.

[0029] Furthermore, refer to Figure 2 To ensure accurate alignment between the door 2 and the fence frame 1, a positioning groove 8 is provided on the limiting plate 32, and a protrusion 9 is provided on the door 2. The positioning groove 8 and the protrusion 9 cooperate with each other. In this way, when the door 2 is closed, the protrusion 9 engages with the positioning groove 8, ensuring accurate positioning of the door 2. This also prevents the rotating handle 31 from getting stuck at the connection between the door and the fence frame when it is turned later.

[0030] Furthermore, in this embodiment, the fence frame 1 and the gate body 2 are provided with fan-shaped grooves 10 for the rotating handle 31 to rotate and for constraining the rotation stroke of the rotating handle 31. The fan-shaped grooves 10 ensure that the rotating handle 31 does not protrude from the surface of the gate body 2 and the fence frame 1, resulting in an aesthetically pleasing overall appearance. Structurally, the boundaries of the fan-shaped grooves 10 also constrain the rotation of the rotating handle 31, preventing excessive rotation of the rotating handle 31.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
