DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The utility model discloses an electric sliding door structure with an anti-pry function, comprising a door frame 1, wherein a door body 2 is arranged on the inner side of the door frame 1;

[0021] The left and right inner walls of the door frame 1 are clamped with protective plates 11, the upper and lower inner walls of the door frame 1 are provided with slide grooves 12, the upper wall of the door frame 1 is provided with a slide rail 13, the side of the slide rail 13 is provided with a rack 14, a slider 15 is slidably connected to the slide rail 13, the side of the slider 15 is provided with a driving gear 16, an electric push rod 17 is provided in the middle of the door frame 1, the lower end of the electric push rod 17 is fixedly connected with a stop lock 18, and the side of the stop lock 18 is provided with a positioning groove 19;

[0022] A side strip 21 is fixedly connected to the side of the door body 2, a transmission box 22 is arranged in the middle of the side strip 21, a handle 23 is rotatably connected to the front of the transmission box 22, a rotating rod part of the handle 23 is coaxially connected to a winch 24, a steel wire rope 25 is wound on the winch 24, a locking pin 26 is fixedly connected to the end of the steel wire rope 25 away from the winch 24, a positioning block 27 is fixedly connected to the side of the winch 24, and a mechanical lock 28 is fixedly installed inside the transmission box 22.

[0023] Specifically, the upper and lower ends of the door body 2 are slidably connected inside the slide groove 12, and the bottom of the slider 15 is fixedly connected to the door body 2 by bolts; a motor is provided inside the slider 15, and the driving gear 16 is coaxially connected to the central axis of the motor, and the driving gear 16 and the rack 14 are meshed with each other.

[0024] In this embodiment, the door body 2 is slidably connected to the inside of the door frame 1 through the slide groove 12. When the motor in the slider 15 is working, the driving gear 16 rotates accordingly. The driving gear 16 is engaged with the rack 14, pushing the slider 15 to slide on the slide rail 13. The sliding of the slider 15 adjusts the position of the door body 2 in the door frame 1, thereby realizing the opening and closing action of the sliding door.

[0025] Specifically, a slot matched with the stop lock 18 is formed on the upper surface of the edge strip 21, and the positioning groove 19 is matched with the locking pin 26. The side edges of the stop lock 18 and the locking pin 26 are both configured as inclined surfaces.

[0026] In this embodiment, when the electric push rod 17 is working, it drives the stop lock 18 to slide up and down on the upper end of the door frame 1, and extends downward through the stop lock 18 to form a plug-in fixation with the side strip 21, thereby fixing the door body 2. In the process of the stop lock 18 penetrating into the side strip 21, the stop lock 18 and the inclined surfaces on the locking pin 26 contact each other, pushing the locking pin 26 to make way for the stop lock 18. After the stop lock 18 is fully extended, the locking pin 26 extends into the positioning groove 19 to fix the position of the stop lock 18, thereby forming a lock.

[0027] Specifically, the locking pin 26 is slidably connected to the top of the side strip 21, a spring is provided between the locking pin 26 and the inner wall of the side strip 21, the spring and the locking pin 26 are in the same straight line, and the wire rope 25 passes through the spring and is fixedly connected to the locking pin 26 after changing direction through the pulley.

[0028] In this embodiment, the locking pin 26 is pulled by the steel wire 25 to slide on the top of the edge strip 21. When the steel wire 25 no longer pulls the locking pin 26, the locking pin 26 extends toward the positioning groove 19 under the action of the spring.

[0029] Specifically, the lock tongue of the mechanical lock 28 is arranged on a side facing the positioning block 27 , and a slot matching the lock tongue is provided on a side of the positioning block 27 facing the mechanical lock 28 .

[0030] In this embodiment, the mechanical lock 28 is based on the common door lock cylinder setting on the market. When the key is inserted and rotated, the lock tongue extends and retracts with the rotation of the key. When the positioning block 27 is facing the mechanical lock 28, the lock tongue of the mechanical lock 28 is extended and connected with the positioning block 27 to fix the handle 23, making it impossible for the winch 24 to rotate, and then the locking pin 26 cannot be driven out of the positioning groove 19 by external force, so that the stop lock 18 cannot be pried open by external force.

[0031] When in use, the slider 15 drives the door body 2 to move in the door frame 1. When the door body 2 slides to one side of the door frame 1, the electric push rod 17 pushes the stop lock 18 to snap into the top of the side strip 21. During the snapping process of the stop lock 18, the stop lock 18 contacts the inclined surface on the locking pin 26, pushing the locking pin 26 back to make way for the stop lock 18. After the stop lock 18 is fully extended, the positioning groove 19 faces the locking pin 26. The locking pin 26 extends out under the action of the spring to form a snap-fit ​​positioning with the stop lock 18. The mechanical lock 28 is turned by a key so that its lock tongue extends toward the positioning block 27, thereby fixing the capstan 24 and completing the locking of the sliding door. When unlocking, the mechanical lock 28 is turned by a key so that the lock tongue is disengaged from the positioning block 27, and the handle 23 is turned to drive the capstan 24 to rotate. The capstan 24 reels in the wire rope 25, and the wire rope 25 pulls the locking pin 26 back to release its lock on the stop lock 18, so that the stop lock 18 can be retracted by retracting the electric push rod 17 to release the fixation of the door body 2.

[0032] To summarize, the electric sliding door structure with anti-pry function fixes the position of the door body 2 by setting a stop lock 18, and fixes the position of the stop lock 18 by setting a locking pin 26, and the locking pin 26 is pulled by a steel wire rope 25, and then a mechanical lock 28 is set to fix the capstan 24 to prevent it from rotating, forming a multi-pass locking structure for the closed state of the sliding door, adding a positioning structure that needs to be pried open by external force to pry open the door lock, thereby achieving the purpose of anti-pry locking.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
