[0031] The present invention will be further described in detail below with reference to the embodiments given in the accompanying drawings.

[0032] like Figures 1 to 7 As shown, a linkage lock 100 provided by the present invention includes a lock base 1, a lock head body 2, a first locking member 3, a second locking member 4, a first locking member spring 5, a second locking member spring 6 and a linkage member 7.

[0033] The lock body 2 includes a lock body shell 21 fixedly mounted on the lock base 1 and an unlocking rotor 22 rotatably arranged in the lock body shell 21. A slide groove 211 extending along the front and rear directions is also provided in the lock body shell 21. The first locking member 3 is placed in the slide groove 211 and can move forward along the extension direction of the slide groove 211 to be exposed or move backward to retract, and the front end of the first locking member 3 is set as a locking end 3a. The unlocking rotor 22 is provided with a shift block 221 extending into the slide groove 211, and the first locking member 3 is provided with a contact portion 31 located on the rear side of the shift block 221 and in contact with the shift block 221.

[0034] The second locking member 4 and the linkage member 7 are rotatably arranged on the lock base 1 along the upper and lower directions respectively. The lower end of the linkage member 7 is provided with a stopper 71, and the stopper 71 extends into the rear part of the slide groove 211 and is opposite to the rear end of the first locking member 3. The rear end of the slide groove 211 is provided with a rear end opening 2111 for the stopper 71 to extend into. The upper end of the linkage member 7 abuts against the rear side of the lower end of the second locking member 4, and the upper end of the second locking member 4 is set as a locking end 4a.

[0035] When the unlocking rotor 22 is performing the unlocking action (i.e., rotating clockwise), the shift block 221 on the unlocking rotor 22 contacts and cooperates with the contact portion 31 on the first locking member 3, so the shift block 221 can drive the first locking member 3 to move backward, so that the locking end 3a of the first locking member 3 is disengaged from the external locking position matched therewith to achieve unlocking. At the same time, the lower end of the linkage member 7 abuts the top portion 71 and is pushed by the rear end of the first locking member 3 to rotate, thereby triggering the second locking member 4 to rotate, so that the locking end 4a of the second locking member 4 is disengaged from the external locking position matched therewith to achieve unlocking. Specifically, when the lower end of the linkage member 7 abuts the top portion 71 and is pushed by the rear end of the first locking member 3, the linkage member 7 rotates counterclockwise and pushes the lower end of the second locking member 4 forward, forcing the second locking member 4 to rotate clockwise, thereby allowing the locking end 4a of the second locking member 4 to disengage from the external locking position matched therewith to achieve unlocking.

[0036] The first locking member spring 5 is used to maintain the tendency of the first locking member 3 to return to its initial position, and the second locking member spring 6 is used to maintain the tendency of the second locking member 4 to return to its initial position. In other words, when the external force used to unlock the first and second locking members 3 and 4 disappears, the first and second locking members 3 and 4 can return forward under the action of the first and second locking member springs 5 ​​and 6, respectively.

[0037] In a preferred embodiment of the present invention, the lock housing 21 is generally cylindrical, with a slot 211 radially extending from the inner end of the lock housing 21.

[0040] In a preferred embodiment of the present invention, the locking end 3a of the first locking member 3 is provided with a first locking hook 33 with a guiding slope 330, and the locking end 4a of the second locking member 4 is provided with a second locking hook 41 with a guiding slope 410. In other words, during use, the first locking hook 33 with the guiding slope 330 and the second locking hook 41 with the guiding slope 410 can be respectively extended into the external locking position, thereby improving the convenience and reliability of locking.

[0041] In a preferred example of the present invention, the shift block 221 is arranged at the inner end of the unlocking rotor 22, and an avoidance groove 34 is provided on the surface of the first locking member 3 facing the shift block 221. The shift block 221 extends into the avoidance groove 34, and the rear side wall 341 of the avoidance groove 34 constitutes a contact portion 31 that contacts and cooperates with the shift block 221. The front side wall 342 of the avoidance groove 34 is away from the shift block 221 so that the front side wall 342 of the first locking member 3 will not touch the shift block 221 during the backward movement.

[0042] In a preferred example of the present invention, two inclined holes 12 are symmetrically provided at the lower front end of the lock seat 1, and a spring-loaded column 13 is inserted into each of the two inclined holes 12.

The inner end of the lock body shell 21 is also provided with a connecting ear 213, and the connecting ear 213 is fixed to the main body base 1a and the cover body base 1b by a second screw 17. The main body base 1a is also provided with a first opening portion 1a3 for exposing the rear side of the inner end of the lock body shell 21, so that the lower end of the linkage member 7 can reach the top 71 and extend into the rear part of the slide groove 211 at the inner end of the lock body shell 21. The cover body base 1b is provided with a second opening portion 1b3 for exposing the locking end 3a of the first locking member 3.

[0045] like Figures 8 to 13 As shown, the present invention also provides an application example of the above-mentioned interlocking lock 100 on a vehicle-mounted tube-mounted battery 9. The vehicle-mounted tube-mounted battery 9 includes a vehicle beam tube 91, a battery 92 and a cover plate 93. The vehicle beam tube 91 is provided with a battery compartment 94. The battery compartment 94 is provided with a battery access port 95. The battery 92 is loaded into the battery compartment 94 from the battery access port 95. The cover plate 93 covers the battery access port 95 to close the battery compartment 94. The interlocking lock 100 is arranged at one end in the battery compartment 94 and is fixed to the bottom wall 940 of the battery compartment 94 by means of screws 18 through the fixing holes 1a11 on the aforementioned fixing plate 1a1. The corresponding interlocking lock 100 end of the battery 92 is provided with a first locking position 921. The corresponding interlocking lock 100 end of the cover plate 93 is provided with a second locking position 931. The first locking hook 33 of the locking end 3a of the first locking member 3 and the second locking hook 41 of the locking end 4a of the second locking member 4 extend into the first locking member 3 respectively. The stop position 921 and the second locking position 931 are used to lock the battery 92 and the cover plate 93. At this time, only by inserting the key 8 matching the unlocking rotor 22 into the keyhole 222 and then turning the unlocking rotor 222 to unlock the battery 92 and the cover plate 93 can the battery 92 and the cover plate 93 be unlocked, thereby greatly improving the safety of the vehicle-mounted tube-hidden battery 9 during use. A key insertion port 96 is provided on the side wall of the beam tube 91 or the battery compartment 94 at the position corresponding to the keyhole 222 of the unlocking rotor 22.

[0046] Moreover, in this application example, when the battery 92 is installed in the battery compartment 94 and is locked, the aforementioned spring-loaded support column 13 of the interlocking lock 100 is pressed by the end of the battery 92 and retracts into the inclined hole 12. When the battery 92 is unlocked, the aforementioned spring-loaded support column 13 of the interlocking lock 100 pops out of the inclined hole 12 and forces the end of the battery 92 to tilt upward, which facilitates the removal operation of the battery 92 after unlocking.

[0047] At the same time, a limiting boss 922 is provided at the end of the battery 92, and the first locking position 921 is opened on the limiting boss 922. When the battery 92 is installed in the battery compartment 94, the limiting boss 921 enters between the aforementioned two limiting baffles 14 of the interlocking lock 100, thereby avoiding the battery 92 from shaking left and right after installation, and ensuring that the locking end 3a of the first locking member 3 can be kept in an aligned position with the first locking position 921.

[0048] In addition, one end of the corresponding interlocking lock 100 of the battery 92 is also provided with a first guide portion located below the first locking position 921. When the battery 92 is installed in the battery compartment 94, the first guide portion presses against the guide slope 330 of the first lock hook 33 and forces the first locking member 3 to move backward until the first lock hook 33 is aligned with the first locking position 921. The first locking member 3 moves forward and resets under the action of the first locking member spring 5, thereby allowing the first lock hook 33 to extend into the first locking position 921, thereby facilitating automatic locking of the battery. One end of the corresponding interlocking lock 100 of the cover 93 is also provided with a second guide portion located below the second locking position 931. When the cover 93 is closed on the battery access port 95, the second guide portion presses against the guiding slope 410 of the second lock hook 41 and forces the second locking member 4 to rotate backward until the second lock hook 41 is aligned with the second locking position 931. The second locking member 4 rotates forward and resets under the action of the second lock member spring 6, thereby allowing the second lock hook 41 to extend into the second locking position 931, thereby facilitating the automatic locking of the cover 93.

[0049] The above is only a preferred embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. In other words, simple equivalent changes and modifications made according to the scope of the patent application and the content of the invention description are still within the scope of the patent of the present invention.
