Detailed Implementation Methods

[0029] Example 1

[0030] A magnetically adjustable length locking mechanism, such as... Figures 1 to 4 As shown, the lock includes a lock tongue 1, a pawl 2, and a controller (not shown). The lock tongue 1 is surrounded by a cylindrical outer sleeve 3. An inner sleeve 4, which rotates circumferentially, is fitted between the outer sleeve 3 and the lock tongue 1. The end of the inner sleeve 4 has a pawl hole 40 for mounting and fixing the pawl 2. A pull arm 5, actuated by the pawl 2, is located at the center of the lock tongue 1 and the inner sleeve 4. This pull arm 5 extends or retracts axially from the outer sleeve 3 by the pawl 2. The rear end of the pull arm 5 has a pull arm square hole 50 that mates with the end of the pawl 2's actuating arm. The inner sleeve 4 is provided with corresponding pull arm spiral grooves 6 and inner sleeve spiral grooves 7 in the circumferential and axial directions, respectively. The inner end of the lock body tongue 1 is also provided with a pin hole 9, which is inserted into the pull arm spiral groove 6 on the pull arm 5 by a pin 8, so as to facilitate the relative sliding and thrust connection between the lock body tongue 1 and the pull arm 5 along the pull arm spiral groove 6. The pull arm 5 pulls the lock body tongue 1 to extend or retract by the pin 8. The axial center of the lock body tongue 1 is provided with a lock body tongue hole 51 that cooperates with a part of the pull arm 5. The pin hole 9 is radially connected to the lock body tongue hole 51.

[0031] Continue as Figures 1 to 4As shown, the outer sleeve 3 is provided with inner sleeve spiral groove positioning points 10 for guiding and positioning the inner sleeve spiral groove 7 of the inner sleeve 4 which is transversely moved along the axial direction by 180° outward or inward, and the outer sleeve 3 is also provided with inner sleeve positioning points 11 for positioning the inner sleeve 4 after being transversely moved along the axial direction by 180° outward or inward. Correspondingly, the inner sleeve 4 is provided with inner sleeve positioning holes 12 which are respectively matched with the inner sleeve positioning points 11 after being transversely moved along the axial direction by 180° outward or inward, and the inner sleeve positioning holes 12 are arranged on the two sides of the inner sleeve 4 by 180° in the circumferential direction. The outer sleeve 3 is also connected with a fixed clamping sleeve 13 which is used for connecting to the side wall of the door body by screw cover and through which the lock tongue 1 can be conveniently extended or retracted. In this embodiment, the fixed clamping sleeve 13 is a lug clamping sleeve which is symmetrically arranged with two lugs according to the tongue hole of the panel. The outer side of the fixed clamping sleeve 13 is tightly provided with a panel 14, and the end of the outer sleeve 3 corresponding to the fixed clamping sleeve 13 is also clampingly connected with a rubber sleeve 15 for positioning and guiding the lock tongue 1 which is extended or retracted. The door body is provided with a buckle plate 16 which is matched with the lock tongue 1. The rubber sleeve 15 is also provided with a Hall switch 19 which is electrically connected with a controller through a wire 17 and a socket 18. The buckle plate 16 of the door body is provided with a magnet 20 which is used for magnetically triggering the Hall switch when the door is closed. The outer edge of the rear end of the outer sleeve 3 is also provided with a rubber band ring 21 which is used for circularly bundling and fixing the wire 17 connected with the Hall switch 19. When working, the controller controls the motor (not shown in the figure) arranged at the rear end to drive the knob 2 to rotate according to the magnetic signal sensed by the Hall switch 19.

[0032] Since the outer sleeve 3 is provided with the inner sleeve spiral groove positioning points 10 for guiding and positioning the inner sleeve spiral groove 7 of the inner sleeve 4 which is transversely moved along the axial direction by 180° outward or inward, when the outer sleeve 3 and the inner sleeve 4 rotate in opposite directions, the outer sleeve 3 drives the lock tongue 1 and the panel 14 to rotate along the pull arm spiral groove 6, and the inner sleeve spiral groove positioning points 10 on the outer sleeve 3 rotate along the inner sleeve spiral groove 7. The outer sleeve 3 and the lock tongue 1 are linearly displaced along the axial direction outward or inward between the inner sleeve 4 and the pull arm 5 to adjust the extension length of the lock tongue 1 to adapt to different door edge distances. When the outer sleeve 3 and the lock tongue 1 rotate by 180°, the lock tongue 1 is adjusted to different long and short positions.

[0033] When the door is closed, the motor drives the knob 2 to rotate counterclockwise, and the knob 2 drives the pull arm 5 and the lock tongue 1 to extend through the pull arm square hole 50. When the knob 2 rotates by 90°, the lock tongue 1 is completely extended. When the door is locked, the motor drives the knob 2 to rotate clockwise, and the knob 2 drives the pull arm 5 and the lock tongue 1 to retract through the pull arm square hole 50. When the knob 2 rotates by 90°, the lock tongue 1 is completely retracted.

[0034] Embodiment Two

[0035] As Figure 5 and Figure 6As shown, the embodiment differs from the embodiment one in that the fixed sleeve 13 is a round end sleeve matched with the single round hole door according to the tongue hole of the panel.

[0036] In use, the controller controls the motor to drive the knob to rotate according to the magnetic signal sensed by the Hall switch to automatically lock and unlock the door; in addition, the length of the lock is adjusted according to the door edge distance, and the specific adjustment method is as follows: the outer sleeve 3 rotates relative to the inner sleeve 4, the outer sleeve 3 drives the lock tongue 1 and the fixed sleeve and the panel to rotate synchronously, the pin 8 on the lock tongue 1 rotates along the spiral slot 6 of the pull arm, and the inner sleeve spiral groove positioning point 10 on the outer sleeve 3 rotates along the inner sleeve spiral groove 7 on the inner sleeve 4; when rotating 180 degrees in the forward or reverse direction, the lock tongue 1 is driven to displace axially outward or inward relative to the pull arm 5 to complete the adjustment of the length position.

[0037] The above-described embodiments are only preferred embodiments of the present application, and do not limit the scope of the present application, so that equivalent changes made according to the shape, structure and principle of the present application should be covered within the protection scope of the present application.
