[0023] Refer to Figure 1The utility model provides a kind of narrow body electromechanical escape lock body, including lock shell 100, lock tongue 200, limit dog 300, touch lever 500 and locking assembly 400.Lock shell 100 is provided with through-hole 101 in side part. Lock tongue 200 is slidably connected in lock shell 100, and is located at through-hole 101. Limit dog 300 is connected to lock shell 100, and is adjacent to lock tongue 200, and limit dog 300 is located at the side of lock tongue 200 away from the mouth, with the accommodation groove 340 of accommodating lock tongue 200 retracting, the side of accommodation groove 340 close to lock tongue 200 is open, and the distance of opening is less than the width of lock tongue 200 in normal state, to limit lock tongue 200 retracting lock shell 100. Touch lever 500 is slidably connected to lock shell 100, and touch lever 500 is hinged to limit dog 300, and touch lever 500 moves to drive the distance of opening to increase, and lock tongue 200 can retract accommodation groove 340. Locking assembly 400 includes electromagnet 410 and locking rod 420, electromagnet 410 is connected to lock shell 100, and locking rod 420 is rotatably connected to lock shell 100, and electromagnet 410 is used to adsorb the side of locking rod 420, when locking rod 420 is adsorbed, the end of locking rod 420 abuts touch lever 500, to limit touch lever 500 to move, and limit lock tongue 200 to retract lock shell 100. Lock shell 100 is provided with mounting hole 102, and mounting hole 102 is used for installing lock cylinder, and lock cylinder is located at the lower side of locking assembly 400, and lock shell 100 is also provided with driving block 600, and driving block 600 is adjacent to mounting hole 102, and driving block 600 is connected to the lower part of locking rod 420, and lock cylinder can drive driving block 600 to rotate, to drive locking rod 420 to rotate.

[0024] In specific embodiments, lock shell 100 is used as the basic support structure of the entire lock body, and the side part is provided with through-hole 101 for the extension and retraction of lock tongue 200. Lock tongue 200 is slidably connected in lock shell 100 and located at through-hole 101. Lock tongue 200 extends out of lock shell 100 in normal state, for locking escape door. Limit dog 300 is connected to lock shell 100 and adjacent to lock tongue 200. Limit dog 300 is located at the side of lock tongue 200 away from the mouth, and is provided with accommodation groove 340 for accommodating lock tongue 200 retracting. The side of accommodation groove 340 close to lock tongue 200 is open. It should be noted that the distance of opening of limit dog 300 is less than the width of lock tongue 200 in normal state. Touch lever 500 is slidably connected in lock shell 100 and hinged to limit dog 300. Locking assembly 400 includes electromagnet 410 and locking rod 420. Electromagnet 410 is connected to lock shell 100, and locking rod 420 is rotatably connected to lock shell 100. Although electromagnet 410 does not work when power off, the structure of locking rod 420 and touch lever 500 can form effective locking mechanism when power on.

[0025] When the electromagnet 410 is powered on and the locking rod 420 is attracted, the end of the locking rod 420 will abut the touch rod 500, limiting the movement of the touch rod 500. When unlocking is required, the electromagnet 410 is powered off, the locking rod 420 is not limited by force, and the touch rod 500 can be driven and in turn increase the opening of the limiting pawl 300, and the lock tongue 200 can be retracted.

[0026] It should be noted that, with reference to Figure 1 , the embodiment is provided with a spring or a torsion spring at the limiting pawl 300, and other structures can also be provided to maintain the locking state of the lock tongue 200 in the case of power failure. The lock shell 100 is provided with a mounting hole 102 for mounting the lock cylinder. The lock cylinder is located on the lower side of the locking assembly 400. At the same time, the lock shell 100 is also provided with a driving block 600 adjacent to the mounting hole 102. The driving block 600 is connected to the lower part of the locking rod 420, so that the rotation of the lock cylinder can drive the driving block 600 to rotate, and in turn drive the locking rod 420 to rotate.

[0027] It should be noted that although the locking rod 420 does not directly participate in the unlocking process in the case of power failure, the design of the driving block 600 enables the lock cylinder to indirectly act on the limiting pawl 300 or the touch rod 500 to achieve unlocking.

[0028] With reference to Figure 1 , specifically, the locking rod 420 is composed of an adsorption part 421, a hinged part 422 and a limiting part, which work together to realize the locking and unlocking functions. The adsorption part 421 is used to closely cooperate with the electromagnet 410, and when the electromagnet 410 is powered on, it will generate a strong magnetic force to attract the adsorption part 421 and make it closely adhere. This design ensures the stability of the locking rod 420 in the powered state. The hinged part 422 is connected to the lock shell 100 through a rotating shaft 4221, allowing the locking rod 420 to rotate freely within a certain range. This design enables the locking rod 420 to rotate flexibly according to the attractive force of the electromagnet 410, thereby realizing the switching of locking and unlocking. The end of the limiting part is used to abut the touch rod 500. When the locking rod 420 is attracted by the electromagnet 410 and rotated to a certain position, the limiting part will tightly abut the touch rod 500 to prevent its movement. In this way, the lock tongue 200 is firmly locked in the lock shell 100.

[0029] Further, the electromagnet 410 is arranged on one side of the lock shell 100 close to the through hole 101 and below the lock tongue 200, which not only saves space but also ensures the optimal magnetic force transmission between the electromagnet 410 and the adsorption part 421. At the same time, the length of the adsorption part 421 is at least 3 times that of the limiting part, which increases the contact area between the electromagnet 410 and the adsorption part 421 and enhances the attraction force on the adsorption part 421, thereby improving the stability of the locking rod 420. It should be noted that the adsorption part 421 is arranged in an arc from the hinge part 422 towards the electromagnet 410, so that the adsorption part 421 can rotate more smoothly when attracted by the electromagnet 410, reducing friction and resistance. This optimization not only improves the response speed of the locking rod 420, but also prolongs its service life.

[0030] Referring to Figure 1 , it should be noted that in specific embodiments, the limiting claw 300 is composed of a locking block 310, a guide block 320 and a limiting block 330, which cooperate together to realize the locking and unlocking functions of the lock tongue 200. The locking block 310 is rotatably connected to the lock shell 100 and is the core component of the limiting claw 300. It is fixedly connected with the actuating rod 500 to realize the transmission and control of the movement of the actuating rod 500. The guide block 320 is hingedly connected to both sides of the locking block 310 and is used to guide the movement of the limiting block 330. When the locking block 310 rotates, it will drive the guide block 320 to rotate together, thereby changing the position and posture of the limiting block 330. The limiting block 330 is hingedly connected to the guide block 320, and the accommodation groove 340 formed between them is used to accommodate the lock tongue 200. When the limiting block 330 rotates, the opening of the accommodation groove 340 will increase or decrease, thereby allowing or preventing the retraction of the lock tongue 200.

[0031] Further, in order to improve the sliding efficiency between the limiting block 330 and the lock tongue 200, a first guide bearing 331 is arranged at the end of the limiting block 330 towards the lock tongue 200, which reduces the friction and wear between the limiting block 330 and the lock tongue 200, making the lock tongue 200 retract and extend more smoothly.

[0032] Optionally, the second guide bearing 4231 is arranged at the end of the locking rod 420 close to the actuating rod 500, which not only reduces the friction and resistance between the locking rod 420 and the actuating rod 500, but also improves the rotation efficiency and stability of the locking rod 420. By optimizing the material and size of the second guide bearing 4231, the friction coefficient and wear rate can be further reduced, thereby prolonging the service life of the locking rod 420 and the actuating rod 500. Further optionally, referring to the embodiment shown in Figure 1 , bearings can be arranged at both ends of the limiting block 330, both ends of the guide block 320 and the end of the actuating rod 500 to reduce friction and wear during mechanical operation and reduce noise.

[0033] It should be noted that the lock tongue 200 is composed of the first and second latches 210 and 220 hingedly connected to each other, and the inclined surfaces of the first and second latches 210 and 220 are located on opposite sides of each other. The structure of the bidirectional latch is arranged to automatically fix the door position after closing the door, and can realize opening in either direction, ensuring that the latch structure does not need to be customized according to the left or right direction of opening the door, and does not need to adjust the lock body during installation, thus being simple in structure and convenient to install.

[0034] Referring to Figure 1 It should be noted that the driving block 600 is located on the lower side of the electromagnet 410 and is directly or indirectly connected to the lower part of the locking rod 420. This layout not only makes full use of the space inside the lock shell 100, but also ensures that the locking rod 420 can be efficiently driven when the lock cylinder is rotated. Further, a reset torsion spring 610 is arranged between the lock shell 100 and the driving block 600 to drive the locking rod 420 to maintain the state of closely abutting the electromagnet 410. One end of the reset torsion spring 610 is fixed on the lock shell 100, and the other end is connected to the driving block 600. When the electromagnet 410 is powered and attracts the locking rod 420, the reset torsion spring 610 is in a compressed or stretched state and stores a certain elastic potential energy. Once the electromagnet 410 is powered off, the reset torsion spring 610 releases the potential energy stored therein, drives the driving block 600 and the locking rod 420 connected thereto to move toward the electromagnet 410, so that the locking rod 420 closely abuts the electromagnet 410. After the user completes the opening action by driving the driving block 600 with the lock cylinder to unlock, the locking rod 420 is reset under the driving of the reset torsion spring 610, and the locking rod 420 is reset, thereby returning to the locked state.

[0035] Further, the limiting clamping jaw is provided with a reset member, and the reset member is connected to the lock shell through the reset member. The reset member drives the limiting clamping jaw to reset after the lock tongue is retracted under the elastic force generated by the elastic deformation of the reset member, drives the lock tongue to extend, and maintains the state of abutting the lock tongue, so as to realize the locked state of the lock body during opening or power-off, and only the key can be used to unlock. Alternatively, the reset member can be a reset spring.

[0036] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the utility model.
