Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pet supplies technology and relates to a pet fence lock device. Background Technology
[0002] A pet fence is a safety device that confines a pet to a designated area to prevent it from running away. Typically, a door is installed on one side panel of the pet fence for easy access to the pet. The door is equipped with a lock, usually a bolt. However, if a pet shakes the fence, the bolt can easily be dislodged, rendering the fence ineffective. Utility Model Content
[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a pet fence locking device. This device can lock the lock to the revolving door using an adjustment disc, preventing accidental rotation and opening of the revolving door.
[0004] The purpose of this utility model can be achieved through the following technical solution: A pet fence lock device includes a door frame and a revolving door. The revolving door is rotatably connected inside the door frame. A movable groove 1 is opened on the outer end face of the door frame, and a movable groove 2 is opened on the outer end face of the revolving door, which is directly opposite to the movable groove 1. The feature is that a lock for locking the revolving door is rotatably connected in the movable groove 1. The lock includes an upper cover, a bottom cover, and a rotating sleeve. A connecting hole is opened in the movable groove 1. The upper cover and the bottom cover are fastened together. The upper cover has a rotating shaft that is inserted into the connecting hole. The rotating sleeve is against the inner end face of the door frame and is engaged with the rotating shaft. An adjusting plate is rotatably connected to the upper cover. A vertical sliding groove is opened on the bottom cover. A locking block is slidably arranged in the sliding groove. A square hole is opened on the locking block. A hook portion is opened on the adjusting plate for inserting into the square hole. A locking hole for inserting the locking block is opened in the movable groove 2. After the adjusting plate is rotated, the locking block is pushed toward or pulled away from the locking hole.
[0005] Furthermore, the top cover has an adjustment hole, and the adjustment plate has an adjustment protrusion that extends out of the adjustment hole.
[0006] With the lock in a horizontal position, move the adjustment disc to the left end of the adjustment hole. The lock block will insert into the locking hole, and the lock will be locked and cannot be rotated. Move the adjustment disc to the right end of the adjustment hole, and the lock will be unlocked and can be rotated freely. Rotate the lock to a vertical position, and the revolving door can be opened outwards.
[0007] Furthermore, a step is provided on the door frame. After the revolving door rotates, its edge rests against the step, and a limiting groove aligned with the locking hole is provided on the step. The step is used to prevent the revolving door from continuing to rotate and to prevent the revolving door from opening inward.
[0008] Furthermore, the top cover and bottom cover are fastened together with bolts.
[0009] Furthermore, the bottom cover has an elastic positioning rod with a positioning protrusion at the end, and the adjustment plate has a locking groove and an unlocking groove for the positioning protrusion to be inserted.
[0010] When the adjusting disc is rotated counterclockwise, the lock block is fully pressed into the locking hole. The positioning protrusion then falls into the locking groove, preventing the entire lock from rotating and unlocking. Rotating the adjusting disc clockwise pulls the lock block out of the locking hole. Once fully pulled out, the positioning protrusion falls into the unlocking groove, allowing the lock to be rotated from a horizontal to a vertical position. The outer end of the lock moves out of the second movable groove, allowing the revolving door to open outwards.
[0011] Compared with existing technologies, this pet fence locking device has the following advantages:
[0012] 1. The structure is simple and sturdy, and it is easy to install and disassemble. The entire lock can be removed by separating the rotating sleeve from the rotating shaft.
[0013] 2. It has an adjustment disc and a locking block. The adjustment disc drives the locking block to insert into the locking hole of the revolving door, locking the lock to the revolving door so that it cannot be rotated, thereby improving security and preventing the lock from being accidentally rotated and opening the revolving door.

Detailed Implementation
[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0023] like Figure 1 , Figure 2 As shown, this pet fence locking device includes a door frame 1 and a rotating door 2. The rotating door 2 is rotatably connected inside the door frame 1. A movable groove 3 is opened on the outer end face of the door frame 1, and a movable groove 4 is opened on the outer end face of the rotating door 2, which is directly opposite to the movable groove 3. A lock 5 that locks the rotating door 2 is rotatably connected inside the movable groove 3.
[0024] like Figure 3 As shown, the lock 5 includes an upper cover 51, a bottom cover 52, and a rotating sleeve 53. A connecting hole 31 is opened in the first movable groove 3. The upper cover 51 and the bottom cover 52 are fastened together. The upper cover 51 has a rotating shaft 511 that is inserted into the connecting hole 31. The rotating sleeve 53 is attached to the inner end face of the door frame 1 and is engaged with the rotating shaft 511. An adjusting plate 54 is rotatably connected to the upper cover 51. A vertical sliding groove 521 is opened on the bottom cover 52. A lock block 55 is slidably arranged in the sliding groove 521. A square hole 551 is opened on the lock block 55. The adjusting plate 54 has a hook part 541 for inserting into the square hole 551. A locking hole 41 for the lock block 55 to be inserted is opened on the second movable groove 4. After the adjusting plate 54 rotates, it pushes or pulls the lock block 55 toward or away from the locking hole 41.
[0025] like Figure 4-7 As shown, the upper cover 51 has an adjustment hole 512, and the adjustment disc 54 has an adjustment protrusion 542 extending out of the adjustment hole 512. When the lock 5 is in a horizontal position, moving the adjustment disc 54 to the left end of the adjustment hole 512 causes the locking block 55 to insert into the locking hole 41, at which point the lock 5 is locked and cannot be rotated; moving the adjustment disc 54 to the right end of the adjustment hole 512 unlocks the lock 5, allowing it to rotate freely. Rotating the lock 5 to a vertical position allows the revolving door 2 to be opened outwards.
[0026] A step 11 is provided on the door frame 1. After the revolving door 2 rotates, its edge rests against the step 11. A limiting groove 12 is provided on the step 11, which is aligned with the locking hole 41. The step 11 is used to prevent the revolving door 2 from continuing to rotate and to prevent the revolving door 2 from opening inward.
[0027] After the upper cover 51 and the bottom cover 52 are fastened together, they are secured with bolts. The bottom cover 52 has an elastic positioning rod 522, and the end of the elastic positioning rod 522 has a positioning protrusion 523. The adjusting plate 54 has a locking groove 542 and an unlocking groove 544 for the positioning protrusion 523 to be inserted.
[0028] Working principle: When the adjusting disc 54 is rotated counterclockwise, the locking block 55 is fully pressed into the locking hole 41. At this time, the positioning protrusion 523 falls into the locking groove 542, and the entire lock 5 cannot rotate, thus preventing the adjusting disc 54 from rotating arbitrarily and unlocking. When the adjusting disc 54 is rotated clockwise, the hook part 541 pulls the locking block 55 out of the locking hole 41. After it is fully pulled out, the positioning protrusion 523 falls into the unlocking groove 544. After unlocking, the lock 5 can be rotated from a horizontal position to a vertical position. The outer end of the lock 5 leaves the movable groove 4, and the revolving door 2 can be opened outward.
[0029] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
