Description
Technical Field
[0001] The utility model belongs to the technical field of lock structures and relates to a double-lock tongue structure lock with adjustable lock tongue height. Background Art
[0002] Most battery boxes on the market use glue encapsulation to fix the battery pack. After the battery pack is placed in the lower cover of the battery box, it is encapsulated with glue, and then the upper cover of the battery box is closed, and the opening is sealed with glue. Although this can stably and conveniently fix the battery pack and the protection board structure, it will also bring corresponding problems. For example, power supply problems caused by aging or poor contact of internal components of the battery pack, or battery pack short circuits caused by other reasons, when after-sales maintenance is required, adopting this solution will make after-sales maintenance extremely difficult or even impossible, and the problem parts will be directly scrapped. Since battery packs are relatively expensive, this method will cause great economic losses to customers and after-sales.

A height-adjustable adjustment lock tongue 10 is provided on the front side of the first lock tongue 5.
[0027] When in use, the first lock tongue 5 and the second lock tongue 7 need to be opened in sequence. The first lock tongue 5 is controlled by the lock core 3, and the second lock tongue 7 is controlled by the unlocking lever 8. The first unlocking controlled by the lock core 3 can effectively remind the staff and reduce the probability of damage to the items caused by accidental unlocking;
[0028] By adjusting the height of the adjusting lock tongue 10 relative to the first lock tongue 5, the adjusting lock tongue 10 can be adapted to the tolerance gap generated during the installation of the lock body, thereby increasing the overall applicability of the device;
[0029] When unlocking is needed, the lock shell 1 is installed on the lower cover, the lower side surface of the adjustment lock tongue 10 contacts and cooperates with the card slot of the battery box, and the lock cylinder 3 is operated by the key, so that the output end of the lock cylinder 3 drives the power component 4 to rotate. At this time, the first lock tongue 5 moves backward and the connecting rod 6 moves forward. As the first lock tongue 5 moves backward, the adjustment lock tongue 10 will be driven to move backward together. At this time, since the adjustment lock tongue 10 is lower than the second lock tongue 7, when the adjustment lock tongue 10 is released from the card slot of the battery box, the lock shell 1 will move downward with the lower cover relative to the battery box. The movement distance is equal to the height difference between the lower side surface of the adjustment lock tongue 10 and the lower side surface of the second lock tongue 7. At this time, the second lock tongue 7 contacts and cooperates with the card slot of the battery box, reminding the staff. When the staff is sure that there is no wrong operation, they can press the unlocking lever 8, and the unlocking lever 8 drives the second lock tongue 7 to move backward, and the lower cover is fully opened.
[0030] Further, by Figure 1-Figure 5In order to increase the reminder function for the staff, the right side of the power component 4 is fixedly connected with a first power block 11 and a second power block 12. The front side of the first power block 11 abuts a first connecting block 13, and the first connecting block 13 is fixedly connected to the front side of the connecting rod 6.

[0032] Further, by Figure 1-Figure 5 It is given that the locking groove 9 is convex, and a first inclined surface 20 is provided on the right side of the unlocking lever 8. An extension block is fixedly connected to the lower side of the rear end of the second lock tongue 7, and the extension block is located on the rear side of the first inclined surface 20. A reset groove 21 is provided in the middle of the unlocking lever 8, and a reset spring 22 is provided on the left side of the reset groove 21. The right side of the reset spring 22 abuts against the dust cover 2. A fixed block is provided inside the dust cover 2 for tightening the right side of the reset spring 22 to provide a force for the unlocking lever 8 to move to the left. An unlocking button 23 is connected to the left side of the unlocking lever 8 by a bolt.
[0033] During use, when the first locking tongue 5 is in a forward extended state, under the action of the return spring 22, the first connecting block 13 drives the connecting rod 6 to move backward. At this time, the connecting rod 6 is located at the rear end of the locking groove 9, and the unlocking rod 8 is in a locked state and cannot move left or right. When the power component 4 rotates, the first locking tongue 5 moves backward and the connecting rod 6 moves forward. The connecting rod 6 is at the front of the locking groove 9, and the unlocking rod 8 can move left or right. At this time, the staff needs to operate with both hands, one hand to operate the key and the other hand to press the unlocking button 23, which can effectively remind the staff of improper operation.
[0034] Further, by Figure 1-Figure 5 In order to facilitate the maintenance of the lock body, a first limiting groove 17 is provided on the upper side of the first lock tongue 5, and a second limiting groove 18 is provided on the right side of the second lock tongue 7.

[0037] When in use, since the first lock tongue 5 and the second lock tongue 7 are respectively controlled to extend and retract by the first spring 24 and the second spring 25, the first inclined surface 20 on the right side of the unlocking rod 8 is located in front of the rear end extension block of the second lock tongue 7. Therefore, the first lock tongue 5 and the second lock tongue 7 can move freely backward when pressed backward by external force. When the lower cover is closed, the first lock tongue 5 and the second lock tongue 7 can move backward under the action of the corresponding inclined surfaces, thereby locking the lower cover.
[0038] Further, by Figure 1-Figure 5 In order to facilitate the adjustment of the lock tongue height, an adjusting screw 26 is threadedly connected to the front of the first lock tongue 5, and the lower side of the adjusting screw 26 abuts against the adjusting lock tongue 10. A torsion spring 27 is provided on the right side of the first lock tongue 5, and a groove is provided on the rear side of the adjusting lock tongue 10. The upper end of the torsion spring 27 abuts against the upper side of the groove on the rear side of the adjusting lock tongue 10;
[0039] During use, by rotating the adjusting screw 26, the adjusting lock tongue 10 can be pushed downward to adjust the height of the adjusting lock tongue 10 relative to the first lock tongue 5. After rotating the adjusting screw 26 in the opposite direction, under the action of the torsion spring 27, a force can be provided to move the adjusting lock tongue 10 upward, thereby resetting the height of the adjusting lock tongue 10.
[0040] Further, by Figure 1-Figure 5 In order to increase the height stability of the adjustment lock tongue 10, a fixing screw 28 is threadedly connected to the left side of the adjustment lock tongue 10, and a waist groove 29 is opened on the left side of the first lock tongue 5, and the middle part of the fixing screw 28 cooperates with the waist groove 29;
[0041] During use, after the height of the adjustment lock tongue 10 is adjusted by the adjustment screw 26, the fixing screw 28 can be rotated so that the fixing screw 28 can fix the relative height between the adjustment lock tongue 10 and the first lock tongue 5 through the friction force of the waist-shaped groove 29.
[0042] Further, by Figure 1-Figure 5 It is given that, in order to facilitate the replacement of the lock cylinder 3, a threaded rod 30 is provided on the upper side of the rear portion of the power component 4 and is threadedly connected to the lock housing 1;
[0043] During use, the lock core 3 can be replaced after the threaded rod 30 is removed.
[0044] When the utility model is used, the first lock tongue 5 and the second lock tongue 7 need to be opened in sequence. The first lock tongue 5 is controlled by the lock core 3, and the second lock tongue 7 is controlled by the unlocking lever 8. The first unlocking controlled by the lock core 3 can effectively remind the staff and reduce the probability of damage to the items caused by accidental unlocking.
[0045] By adjusting the height of the adjusting lock tongue 10 relative to the first lock tongue 5, the adjusting lock tongue 10 can be adapted to the tolerance gap generated during the installation of the lock body, thereby increasing the overall applicability of the device;
[0046] When unlocking is needed, the lock shell 1 is installed on the lower cover, the lower side surface of the adjustment lock tongue 10 contacts and cooperates with the card slot of the battery box, and the lock cylinder 3 is operated by the key, so that the output end of the lock cylinder 3 drives the power component 4 to rotate. At this time, the first lock tongue 5 moves backward and the connecting rod 6 moves forward. As the first lock tongue 5 moves backward, the adjustment lock tongue 10 will be driven to move backward together. At this time, since the adjustment lock tongue 10 is lower than the second lock tongue 7, when the adjustment lock tongue 10 is released from the card slot of the battery box, the lock shell 1 will move downward with the lower cover relative to the battery box. The movement distance is equal to the height difference between the lower side surface of the adjustment lock tongue 10 and the lower side surface of the second lock tongue 7. At this time, the second lock tongue 7 contacts and cooperates with the card slot of the battery box, reminding the staff. When the staff is sure that there is no wrong operation, they can press the unlocking lever 8, and the unlocking lever 8 drives the second lock tongue 7 to move backward, and the lower cover is fully opened.
