Description

TECHNICAL FIELD

[0001] The present invention belongs to the technical field of lock structures, and specifically relates to a structure lock with an adjustable bolt height.BACKGROUND

[0002] Most battery boxes on the market use potting encapsulation to fix the battery pack. After placing the battery pack into the lower cover of the battery box, potting encapsulation is performed, then the upper cover of the battery box is placed on, and the opening is sealed with glue. Although this method can fix the battery pack and the protection board structure stably and conveniently, it also brings corresponding problems, such as power supply problems caused by aging of internal components of the battery pack or poor contact, or short circuits of the battery pack caused by other reasons. When after-sales maintenance is required, this method makes after-sales maintenance extremely difficult, or even impossible, and the defective unit is directly scrapped. Since the battery pack is relatively expensive, this method causes significant economic losses to both the customer and the after-sales service.

[0003] To solve the above-mentioned problems, the lower cover of the battery box can be designed to be openable and closable, and a structure lock can be used to lock the lower cover onto the battery box, thereby realizing the maintenance function of the battery pack. However, during the use of the battery box, because the bolt height of traditional structure locks is fixed, it cannot adapt to the tolerance clearance generated during the installation of the lock body, resulting in poor applicability, which directly affects the locking effect between the lower cover and the battery box.SUMMARY

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are a part of the embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Therefore, the detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.Embodiment 1

[0025] As shown in FIGS. 1-4, a structure lock with an adjustable bolt height includes a lock housing 1 internally provided with a lock cylinder 3, wherein an output end of the lock cylinder 3 is connected with a drive part 4, a first bolt 5 moving with the rotation of the drive part 4 is disposed on a right side of the drive part 4, and a height-adjustable adjusting bolt 10 is disposed on a front side of the first bolt 5.

[0026] The axial direction of the lock cylinder 3 is perpendicular to the movement direction of the first bolt 5. In this embodiment, the axis of the lock cylinder 3 is in the left-right direction, and the movement direction of the first bolt 5 is in the front-rear direction.

[0027] The height difference between the bottom of the adjusting bolt 10 and the bottom of the first bolt 5 is adjusted by the upward and downward movement of the adjusting bolt 10. By adjusting the height of the adjusting bolt 10 relative to the first bolt 5, the adjusting bolt 10 can be adapted to the tolerance clearance generated during the installation of the lock body, thereby increasing the overall applicability of the device.

[0028] After moving the adjusting bolt 10 to a desired position, the relative positions of the adjusting bolt 10 and the first bolt 5 can be locked to ensure the stability of the structure lock.

[0029] To facilitate the downward adjustment of the height of the adjusting bolt 10, the adjusting bolt 10 is threadedly connected with an adjusting screw 26, and the upper side of the adjusting screw 26 abuts against the first bolt 5.

[0030] Specifically, the adjusting bolt 10 is provided with a threaded hole at a position located below the first bolt 5. The adjusting screw 26 is installed in the threaded hole. When the adjusting bolt 10 cooperates with the first bolt 5, the upper end of the adjusting screw 26 abuts against the first bolt 5.

[0031] Preferably, the first bolt 5 is provided with a vertical through-hole at a position corresponding to the adjusting screw 26, thus facilitating the insertion of a wrench through the through-hole to cooperate with the adjusting screw 26 to drive the adjusting screw 26 to rotate.

[0032] To achieve upward reset movement of the adjusting bolt 10, the first bolt 5 is provided with an accommodating cavity 31 with an opening facing upward. An adjusting spring 32 is installed in the accommodating cavity 31. A protrusion 33 covering the top of the accommodating cavity 31 is disposed on the top rear side of the adjusting bolt 10. The upper end of the adjusting spring 32 abuts against the protrusion 33.

[0033] In use, by rotating the adjusting screw 26 upward, the adjusting bolt 10 can be driven to move downward, thereby adjusting the height of the adjusting bolt 10 relative to the first bolt 5. After rotating the adjusting screw 26 in the reverse direction, the adjusting spring 32 provides a force for the adjusting bolt 10 to move upward, thereby resetting the height of the adjusting bolt 10.

[0034] To increase the height stability of the adjusting bolt 10, a fixing screw 28 is threadedly connected with the left side of the adjusting bolt 10. An elongated slot 29 is disposed in the left side surface of the first bolt 5. The middle part of the fixing screw 28 cooperates with the elongated slot 29.

[0035] The adjusting bolt 10 as a whole forms an irregular L-shaped structure and cooperates with the right front end of the first bolt 5, i.e., the right side of the adjusting bolt 10 extends rearward and cooperates with the front right side of the first bolt 5. The fixing screw 28 is arranged transversely. The first bolt 5 is provided with a transverse elongated through-hole, and the elongated slot 29 is located on the outside of the elongated through-hole. The fixing screw 28 passes through the elongated through-hole and is threadedly connected with the adjusting bolt 10, and the head of the fixing screw 28 is disposed in the elongated slot 29.

[0036] In use, after the height of the adjusting bolt 10 is adjusted by the adjusting screw 26, the fixing screw 28 can be rotated to fix the relative height between the adjusting bolt 10 and the first bolt 5 by means of the frictional force from the cooperation between the fixing screw 28 and the elongated slot 29.

[0037] To enable the rotation of the lock cylinder 3 to drive the first bolt 5 and the adjusting bolt 10 to unlock, a first drive block 11 is disposed on the right side surface of the drive part 4, and the rear side surface of the first drive block 11 abuts against the front side surface of a driving block 34 located at the rear end of the first bolt 5.

[0038] Specifically, the driving block 34 is located at the rear left side of the first bolt 5, and its front side surface abuts against the rear side surface of the first drive block 11. When the lock cylinder 3 is rotated with a key, the first drive block 11 can push the first bolt 5 and the adjusting bolt 10 connected thereto to move rearward synchronously through the driving block 34, thereby achieving the unlocking action.

[0039] To achieve the effect of automatic locking, a first spring 24 is disposed at the rear end of the first bolt 5, and the rear side surface of the first spring 24 abuts against the lock housing 1.

[0040] Specifically, a groove for placing the first spring 24 is provided at the lower right corner of the rear end of the first bolt 5, and the rear end of the first spring 24 abuts against the inner wall of the lock housing 1.

[0041] In the unlocked state, the rearward movement of the first bolt 5 compresses the first spring 24. When the lower cover is closed, the lock cylinder 3 rotates back to reset, and the first bolt 5 moves forward to reset under the elastic force of the first spring 24, thereby achieving automatic locking.

[0042] To guide and limit the movement of the first bolt 5, a first limit slot 17 is disposed on the first bolt 5. A limit block 19 is disposed inside the lock housing 1 and cooperates with the first limit slot 17 to limit the stroke of the first bolt 5.

[0043] The limit block 19 is threadedly connected with the lock housing 1, which facilitates maintenance of the lock body, as well as the disassembly, maintenance, and replacement of the first bolt 5.

[0044] To facilitate the replacement of the lock cylinder 3, the drive part 4 is provided with a threaded rod 30 which is threadedly connected with the lock housing 1.

[0045] The drive part 4 is provided with an annular slot 35. The threaded rod 30 is threadedly connected with the lock housing 1, and its inner end extends into the lock housing 1 and cooperates with the annular slot 35, which can limit the lock cylinder 3 in the axial direction and prevent the lock cylinder 3 from coming off. When replacing the lock cylinder 3, the threaded rod 30 is screwed out to separate its inner end from the annular slot 35, and then the lock cylinder 3 can be replaced.

[0046] In this embodiment, the threaded rod 30 is located at the rear side of the drive part 4.

[0047] When unlocking is required, at this time, the lock housing 1 is installed on the lower cover, and the lower side surface of the adjusting bolt 10 is in contact and cooperation with a locking slot of the battery box. The lock cylinder 3 is operated with a key, causing its output end to drive the drive part 4 to rotate. At this time, the first drive block 11 drives the first bolt 5 and the adjusting bolt 10 connected thereto to move rearward, the first bolt 5 and the adjusting bolt 10 are removed from the locking slot of the battery box, thus achieving the unlocking operation.

[0048] The structure of this embodiment is novel, the concept is ingenious, and the operation is simple and convenient. Through this design, the adjustment of the bolt height is effectively facilitated, and the function of adapting to the cooperation clearance of the lock is realized.Embodiment 2

[0049] On the basis of Embodiment 1, this embodiment also provides a structure lock with an adjustable bolt height. The structure of this embodiment is substantially the same as that of Embodiment 1, with the difference being that, an adjusting screw 26 is threadedly connected with the front part of the first bolt 5, and the lower side of the adjusting screw 26 abuts against the adjusting bolt 10.

[0050] The first bolt 5 is provided with a threaded hole at a position above the adjusting bolt 10 in the front part. The adjusting screw 26 is assembled in the threaded hole, and the lower side of the adjusting screw 26 abuts against the adjusting bolt 10.

[0051] By rotating the adjusting screw 26 downward, the adjusting screw 26 can be used to push the adjusting bolt 10 to move downward, thereby adjusting the height of the adjusting bolt 10 relative to the first bolt 5. After the adjusting screw 26 is rotated in the reverse direction, the adjusting spring 32 provides a force for the adjusting bolt 10 to move upward, thereby resetting the height of the adjusting bolt 10.Embodiment 3

[0052] As shown in FIGS. 5-7, on the basis of Embodiment 1, this embodiment also provides a structure lock with an adjustable bolt height. The structure of this embodiment is substantially the same as that of Embodiment 1, with the difference being that, in addition to the first bolt 5 with the adjusting bolt 10, this embodiment is further provided with a second bolt 7 arranged side-by-side with the first bolt 5.

[0053] Specifically, a second bolt 7 capable of moving back and forth is disposed on the right side of the first bolt 5, and the first bolt 5 and the second bolt 7 can be unlocked sequentially.

[0054] To drive the first bolt 5 and the second bolt 7 to unlock sequentially through the rotation of the lock cylinder 3, a first drive block 11 and a second drive block 12 are sequentially disposed on the right side surface of the drive part 4 from left to right. The first bolt 5 is provided with a first assembly slot 36, and the second bolt 7 is provided with a second assembly slot 37. The first drive block 11 cooperates with the first assembly slot 36 and its rear side surface abuts against the rear side inner wall of the first assembly slot 36. The second drive block 12 cooperates with the second assembly slot 37, and a clearance is left between the second drive block 12 and the top inner wall of the second assembly slot 37. After the lock cylinder 3 is rotated, the upper surface of the second drive block 12 abuts against the rear side inner wall of the second assembly slot 37. Through the cooperation of the first drive block 11 with the first assembly slot 36 and the second drive block 12 with the second assembly slot 37, rotating the lock cylinder 3 can drive the first bolt 5 and the second bolt 7 to unlock sequentially.

[0055] The second drive block 12 is a horizontal plate-like structure. When in the locked state, the rear side surface of the first drive block 11 directly abuts against the rear side inner wall of the first assembly slot 36, while a clearance is left between the upper surface of the second drive block 12 and the top inner wall of the second assembly slot 37. When the lock cylinder 3 is rotated to unlock, the first drive block 11 directly drives the first bolt 5 to move rearward. At the same time, the second drive block 12 rotates synchronously until the upper surface of the second drive block 12 rotates to face rearward, i.e., the upper surface abuts against the rear side inner wall of the second assembly slot 37. At this time, the second drive block 12 continues to rotate under the drive of the lock cylinder 3 and then drives the second bolt 7 to move rearward, thereby achieving the effect of sequential unlocking of the first bolt 5 and the second bolt 7.

[0056] To position the rotation of the lock cylinder 3, a positioning pin 38 is disposed on the right side of the second drive block 12. The positioning pin 38 is assembled in an elongated hole 39 on the right side surface of the second bolt 7.

[0057] The elongated hole 39 is located in the front-rear direction. The positioning pin 38 can rotate within the elongated hole 39 along with the lock cylinder 3, and the design of the elongated hole 39 can guide the front-rear movement of the second bolt 7.

[0058] To achieve automatic locking, a first spring 24 is disposed at the rear side of the first bolt 5, and a second spring 25 is disposed at the rear side of the second bolt 7. The rear side surfaces of the first spring 24 and the second spring 25 both abut against the lock housing 1.

[0059] During the process of rotating the lock cylinder 3 to unlock the first bolt 5 and the second bolt 7, the first spring 24 and the second spring 25 are compressed. After the lower cover is closed, the lock cylinder 3 rotates back to reset. The first bolt 5 moves forward to reset under the elastic force of the first spring 24 to achieve automatic locking. Similarly, the second bolt 7 also moves forward to reset under the elastic force of the second spring 25 to achieve automatic locking.

[0060] Preferably, assembly pins 40 are respectively disposed at the rear ends of the first bolt 5 and the second bolt 7. The first spring 24 is installed on the assembly pin 40 at the rear end of the first bolt 5 to position the first spring 24. Similarly, the second spring 25 is installed on the assembly pin 40 at the rear end of the second bolt 7 to position the second spring 25.

[0061] To guide and limit the movement of the bolts, the first bolt 5 is provided with a first limit slot 17, and the second bolt 7 is provided with a second limit slot 18. Two limit blocks 19 are disposed inside the lock housing 1, and the limit blocks 19 cooperate with the first limit slot 17 and the second limit slot 18 respectively to form a structure for limiting the strokes of the first bolt 5 and the second bolt 7.

[0062] Specifically, the first limit slot 17 in this embodiment is provided on the top of the first bolt 5, and the second limit slot 18 is provided on the top of the second bolt 7 and is located between two front-rear opposite stop blocks.

[0063] Similar to Embodiment 1, the limit block 19 is threadedly connected with the lock housing 1, which facilitates maintenance of the lock body, as well as the disassembly, maintenance, and replacement of the bolts. Similarly, in this embodiment, the drive part 4 is provided with a threaded rod 30 threadedly connected with the lock housing 1. The cooperation mode and arrangement position with the drive part 4 are the same as in Embodiment 1.

[0064] Batteries on the market are generally installed in an inverted manner. When the battery box is opened, the batteries will fall out by themselves due to gravity, especially when the operator makes a misoperation, which can easily cause the batteries to fall.

[0065] In this embodiment, by designing the first bolt 5 and the second bolt 7 that open sequentially, and the adjusting bolt 10 with a height adjustment function, not only can the height of the adjusting bolt 10 relative to the first bolt 5 be adjusted to make the adjusting bolt 10 adapt to the tolerance clearance generated during the installation of the lock body, thus increasing the overall applicability of the device, but also the change in the height difference of the bolts after the first bolt 5 is opened can be used to remind the operator, thus reducing the probability of accidental opening by the operator and avoiding the problem of batteries falling.

[0066] In this embodiment, the assembly relationship among the first bolt 5, the adjusting screw 26, and the adjusting bolt 10 adopts the manner in Embodiment 1, and the cooperation manner in Embodiment 2 is also applicable.Embodiment 4

[0067] As shown in FIGS. 8-12, on the basis of Embodiment 3, this embodiment also provides a structure lock with an adjustable bolt height. The structure of this embodiment is substantially the same as that of Embodiment 3, with the difference being that the first bolt and the second bolt in this embodiment are provided with independent unlocking structures respectively, and the first bolt and the second bolt are also unlocked sequentially.

[0068] A structure lock with an adjustable bolt height includes a lock housing 1 and a dust cover 2 that are interconnected. To facilitate the adaptation to the cooperation clearance of the lock, the dust cover 2 is detachably connected with the rear side of the lock housing 1 by bolts. A lock cylinder 3 is disposed inside the lock housing 1. The output end of the lock cylinder 3 is connected with a drive part 4. A first bolt 5 and a connecting rod 6 that move in opposite directions as the drive part 4 rotates are disposed on the right side of the drive part 4. A second bolt 7 capable of moving back and forth is disposed on the right side of the first bolt 5. An unlocking rod 8 capable of moving left and right is disposed inside the dust cover 2. The right side of the unlocking rod 8 is slidably connected with the rear side of the second bolt 7. A locking slot 9 is disposed on the upper side of the unlocking rod 8. The rear end of the connecting rod 6 is slidably connected with the locking slot 9. The connecting rod 6 and the locking slot 9 cooperate with each other to form a structure for sequential unlocking of the first bolt 5 and the second bolt 7. A height-adjustable adjusting bolt 10 is disposed on the front side of the first bolt 5.

[0069] In use, the first bolt 5 and the second bolt 7 need to be opened sequentially. The first bolt 5 is controlled by the lock cylinder 3, and the second bolt 7 is controlled by the unlocking rod 8. The first unlocking controlled by the lock cylinder 3 can effectively remind the operator, reducing the probability of damage to articles caused by accidental unlocking.

[0070] By adjusting the height of the adjusting bolt 10 relative to the first bolt 5, the adjusting bolt 10 can be made to adapt to the tolerance clearance generated during the installation of the lock body, thereby increasing the overall applicability of the device.

[0071] When unlocking is required, at this time, the lock housing 1 is installed on the lower cover, and the lower side surface of the adjusting bolt 10 is in contact and cooperation with the locking slot of the battery box. The lock cylinder 3 is operated with a key, so that the output end of the lock cylinder 3 drives the drive part 4 to rotate. At this time, the first bolt 5 moves rearward, and the connecting rod 6 moves forward. As the first bolt 5 moves rearward, it drives the adjusting bolt 10 to move rearward together. At this time, because the adjusting bolt 10 is at a lower position relative to the second bolt 7, when the adjusting bolt 10 disengages from the locking slot of the battery box, the lock housing 1 moves downward relative to the battery box along with the lower cover. This movement distance is equal to the height difference between the lower side surface of the adjusting bolt 10 and the lower side surface of the second bolt 7. At this time, the second bolt 7 is in contact and cooperation with the locking slot of the battery box, reminding the operator. After the operator confirms that there is no misoperation, the unlocking rod 8 can be pressed. The unlocking rod 8 drives the second bolt 7 to move rearward, thus completely opening the lower cover.

[0072] To increase the reminder function for the operator, a first drive block 11 and a second drive block 12 are fixedly connected with the right side surface of the drive part 4. A first connecting block 13 abuts against the front side of the first drive block 11. The first connecting block 13 is fixedly connected with the front side of the connecting rod 6. The connecting rod 6 is slidably connected with the first bolt 5. A second connecting block 14 abuts against the rear side of the second drive block 12. The second connecting block 14 is fixedly connected with the rear side of the first bolt 5.

[0073] A first slot 15 is disposed in the middle of the first bolt 5. The first connecting block 13 is slidably connected with the first slot 15. A connecting spring 16 is disposed on the front side of the first connecting block 13, and the front side of the connecting spring 16 abuts against the front side surface of the first slot 15.

[0074] The locking slot 9 is in a T shape. A first inclined surface 20 is disposed on the right side surface of the unlocking rod 8. An extension block is fixedly connected with the lower side of the rear end of the second bolt 7. The extension block is located at the rear side of the first inclined surface 20. A return slot 21 is disposed in the middle of the unlocking rod 8. A return spring 22 is disposed on the left side surface of the return slot 21, and the right side surface of the return spring 22 abuts against the dust cover 2. A fixing block is disposed inside the dust cover 2 for pressing against the right side surface of the return spring 22 to provide a force for the unlocking rod 8 to move leftward. The left side of the unlocking rod 8 is connected with an unlocking button 23 by a bolt.

[0075] In use, when the first bolt 5 is in the forward extended state, under the action of the return spring 22, the first connecting block 13 drives the connecting rod 6 to move rearward. At this time, the connecting rod 6 is located at the rearmost part of the locking slot 9, and the unlocking rod 8 is in a locked state and cannot move left or right. When the drive part 4 rotates, the first bolt 5 moves rearward, and at the same time, the connecting rod 6 moves forward. The connecting rod 6 is located at the front part of the locking slot 9, and the unlocking rod 8 can then move left and right. At this time, the operator needs to operate with both hands, one hand operating the key and the other hand pressing the unlocking button 23, which can effectively remind the operator against misoperation.

[0076] To facilitate maintenance of the lock body, a first limit slot 17 is disposed on the first bolt 5, and a second limit slot 18 is disposed on the second bolt 7. Two limit blocks 19 are disposed inside the lock housing 1. The limit blocks 19 cooperate with the first limit slot 17 and the second limit slot 18 respectively to form a structure for limiting the strokes of the first bolt 5 and the second bolt 7.

[0077] In this embodiment, the first limit slot 17 is located on the upper side of the first bolt 5, and the second limit slot 18 is located on the right side of the second bolt 7.

[0078] It should be noted that each limit block 19 is threadedly connected with the lock housing 1, facilitating the disassembly, maintenance, and replacement of the bolts.

[0079] To achieve the effect of direct locking, the first spring 24 abuts against the middle of the first bolt 5, and the second spring 25 abuts against the middle of the second bolt 7. The rear side surfaces of the first spring 24 and the second spring 25 both abut against the lock housing 1. Inclined surfaces are formed on the front sides of the first bolt 5 and the second bolt 7.

[0080] In use, because the first bolt 5 is controlled by the first spring 24 for expansion and retraction, and similarly, the second bolt 7 is controlled by the second spring 25 for expansion and retraction, the first inclined surface 20 on the right side surface of the unlocking rod 8 is located on the front side of the extension block at the rear end of the second bolt 7. Therefore, when the first bolt 5 and the second bolt 7 are pressed backward by an external force, they can both move backward freely. When the lower cover is closed, the first bolt 5 and the second bolt 7 can both move forward under the action of the corresponding springs, thereby locking the lower cover.

[0081] To facilitate the adjustment of the bolt height, the first bolt 5 is threadedly connected with an adjusting screw 26 at the front part. The lower side of the adjusting screw 26 abuts against the adjusting bolt 10. A torsion spring 27 is disposed on the right side surface of the first bolt 5. A slot is formed on the rear side of the adjusting bolt 10. The upper end of the torsion spring 27 abuts against the upper side surface of the slot on the rear side of the adjusting bolt 10.

[0082] In use, by rotating the adjusting screw 26, the adjusting bolt 10 can be pressed downward to adjust the height of the adjusting bolt 10 relative to the first bolt 5. After the adjusting screw 26 is rotated in the reverse direction, the torsion spring 27 provides a force for the adjusting bolt 10 to move upward, thereby resetting the height of the adjusting bolt 10.

[0083] In this embodiment, the torsion spring 27 is used to replace the adjusting spring 32 used in Embodiment 3 to achieve the upward movement of the adjusting bolt 10. Similarly, the torsion spring 27 used in this embodiment and the slot structure cooperating with the torsion spring 27 are also applicable to Embodiments 1, 2, and 3.

[0084] In this embodiment, the assembly relationship among the first bolt 5, the adjusting screw 26, and the adjusting bolt 10 adopts the manner in Embodiment 2, and is also applicable to the cooperation manners disclosed in Embodiments 1 and 3.

[0085] To increase the height stability of the adjusting bolt 10, a fixing screw 28 is threadedly connected with the left side of the adjusting bolt 10. An elongated slot 29 is formed on the left side surface of the first bolt 5. The middle part of the fixing screw 28 cooperates with the elongated slot 29.

[0086] In use, after the height of the adjusting bolt 10 is adjusted by the adjusting screw 26, the fixing screw 28 can be rotated to fix the relative height between the adjusting bolt 10 and the first bolt 5 by means of the frictional force from the cooperation between the fixing screw 28 and the elongated slot 29.

[0087] To facilitate the replacement of the lock cylinder 3, the drive part 4 is provided with a threaded rod 30 threadedly connected with the lock housing 1.

[0088] In this embodiment, the threaded rod 30 is located on the upper side of the rear part of the drive part 4.

[0089] In use, the lock cylinder 3 can be replaced after the threaded rod 30 is removed.

[0090] When the present invention is in use, the first bolt 5 and the second bolt 7 need to be opened sequentially. The first bolt 5 is controlled by the lock cylinder 3, and the second bolt 7 is controlled by the unlocking rod 8. The first unlocking controlled by the lock cylinder 3 can effectively remind the operator, reducing the probability of damage to articles caused by accidental unlocking.

[0091] By adjusting the height of the adjusting bolt 10 relative to the first bolt 5, the adjusting bolt 10 can be made to adapt to the tolerance clearance generated during the installation of the lock body, thereby increasing the overall applicability of the device.

[0092] When unlocking is required, at this time, the lock housing 1 is installed on the lower cover, and the lower side surface of the adjusting bolt 10 is in contact and cooperation with the locking slot of the battery box. The lock cylinder 3 is operated with a key, so that the output end of the lock cylinder 3 drives the drive part 4 to rotate. At this time, the first bolt 5 moves rearward, and the connecting rod 6 moves forward. As the first bolt 5 moves rearward, it drives the adjusting bolt 10 to move rearward together. At this time, because the adjusting bolt 10 is at a lower position relative to the second bolt 7, when the adjusting bolt 10 disengages from the locking slot of the battery box, the lock housing 1 moves downward relative to the battery box along with the lower cover. This movement distance is equal to the height difference between the lower side surface of the adjusting bolt 10 and the lower side surface of the second bolt 7. At this time, the second bolt 7 is in contact and cooperation with the locking slot of the battery box, thus reminding the operator. After the operator confirms that there is no misoperation, the unlocking rod 8 can be pressed. The unlocking rod 8 drives the second bolt 7 to move rearward, thus completely opening the lower cover.

[0093] The structure of this embodiment is novel, the concept is ingenious, and the operation is simple and convenient. Through this design, the adjustment of the bolt height is effectively facilitated, and the function of adapting to the cooperation clearance of the lock is realized. It improves the reminder function for the operator by requiring two unlocking actions, facilitates maintenance of the lock body, and achieves the effect of direct locking, thus increasing the height stability of the adjusting bolt 10.Embodiment 5

[0094] As shown in FIG. 13, on the basis of Embodiment 4, this embodiment also provides a structure lock with an adjustable bolt height. The structure of this embodiment is substantially the same as that of Embodiment 4, with the difference being that this embodiment adopts the structures in Embodiments 1 and 2, i.e., the component for pushing the adjusting bolt 10 to move upward is the adjusting spring 32.

[0095] Specifically, the first bolt 5 is provided with an accommodating cavity 31 with an opening facing upward. An adjusting spring 32 is installed in the accommodating cavity 31. A top rear side of the adjusting bolt 10 is provided with a protrusion 33 covering the top of the accommodating cavity 31. The upper end of the adjusting spring 32 abuts against the protrusion 33.

[0096] In this embodiment, the adjusting spring 32 is used to replace the function of the torsion spring 27 in Embodiment 4. That is, in use, by rotating the adjusting screw 26, the adjusting bolt 10 can be pressed downward to adjust the height of the adjusting bolt 10 relative to the first bolt 5. After the adjusting screw 26 is rotated in the reverse direction, the adjusting spring 32 provides a force for the adjusting bolt 10 to move upward, thereby resetting the height of the adjusting bolt 10.

[0097] For the cooperation relationship among the first bolt 5, the adjusting bolt 10, and the adjusting screw 26, the manners in Embodiments 1 and 2 are both applicable.

[0098] Based on the ideal embodiments of the present invention, those of ordinary skill can make various changes and modifications without departing from the scope of the technical idea of the present invention through the above description. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.

TECHNICAL FIELD

[0001] The present invention belongs to the technical field of lock structures, and specifically relates to a structure lock with an adjustable bolt height.BACKGROUND

[0002] Most battery boxes on the market use potting encapsulation to fix the battery pack. After placing the battery pack into the lower cover of the battery box, potting encapsulation is performed, then the upper cover of the battery box is placed on, and the opening is sealed with glue. Although this method can fix the battery pack and the protection board structure stably and conveniently, it also brings corresponding problems, such as power supply problems caused by aging of internal components of the battery pack or poor contact, or short circuits of the battery pack caused by other reasons. When after-sales maintenance is required, this method makes after-sales maintenance extremely difficult, or even impossible, and the defective unit is directly scrapped. Since the battery pack is relatively expensive, this method causes significant economic losses to both the customer and the after-sales service.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are a part of the embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Therefore, the detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.Embodiment 1

[0025] As shown in FIGS. 1-4, a structure lock with an adjustable bolt height includes a lock housing 1 internally provided with a lock cylinder 3, wherein an output end of the lock cylinder 3 is connected with a drive part 4, a first bolt 5 moving with the rotation of the drive part 4 is disposed on a right side of the drive part 4, and a height-adjustable adjusting bolt 10 is disposed on a front side of the first bolt 5.

[0026] The axial direction of the lock cylinder 3 is perpendicular to the movement direction of the first bolt 5. In this embodiment, the axis of the lock cylinder 3 is in the left-right direction, and the movement direction of the first bolt 5 is in the front-rear direction.

[0027] The height difference between the bottom of the adjusting bolt 10 and the bottom of the first bolt 5 is adjusted by the upward and downward movement of the adjusting bolt 10. By adjusting the height of the adjusting bolt 10 relative to the first bolt 5, the adjusting bolt 10 can be adapted to the tolerance clearance generated during the installation of the lock body, thereby increasing the overall applicability of the device.

[0028] After moving the adjusting bolt 10 to a desired position, the relative positions of the adjusting bolt 10 and the first bolt 5 can be locked to ensure the stability of the structure lock.

[0029] To facilitate the downward adjustment of the height of the adjusting bolt 10, the adjusting bolt 10 is threadedly connected with an adjusting screw 26, and the upper side of the adjusting screw 26 abuts against the first bolt 5.

[0030] Specifically, the adjusting bolt 10 is provided with a threaded hole at a position located below the first bolt 5. The adjusting screw 26 is installed in the threaded hole. When the adjusting bolt 10 cooperates with the first bolt 5, the upper end of the adjusting screw 26 abuts against the first bolt 5.

[0031] Preferably, the first bolt 5 is provided with a vertical through-hole at a position corresponding to the adjusting screw 26, thus facilitating the insertion of a wrench through the through-hole to cooperate with the adjusting screw 26 to drive the adjusting screw 26 to rotate.

[0032] To achieve upward reset movement of the adjusting bolt 10, the first bolt 5 is provided with an accommodating cavity 31 with an opening facing upward. An adjusting spring 32 is installed in the accommodating cavity 31. A protrusion 33 covering the top of the accommodating cavity 31 is disposed on the top rear side of the adjusting bolt 10. The upper end of the adjusting spring 32 abuts against the protrusion 33.

[0033] In use, by rotating the adjusting screw 26 upward, the adjusting bolt 10 can be driven to move downward, thereby adjusting the height of the adjusting bolt 10 relative to the first bolt 5. After rotating the adjusting screw 26 in the reverse direction, the adjusting spring 32 provides a force for the adjusting bolt 10 to move upward, thereby resetting the height of the adjusting bolt 10.

[0034] To increase the height stability of the adjusting bolt 10, a fixing screw 28 is threadedly connected with the left side of the adjusting bolt 10. An elongated slot 29 is disposed in the left side surface of the first bolt 5. The middle part of the fixing screw 28 cooperates with the elongated slot 29.

[0035] The adjusting bolt 10 as a whole forms an irregular L-shaped structure and cooperates with the right front end of the first bolt 5, i.e., the right side of the adjusting bolt 10 extends rearward and cooperates with the front right side of the first bolt 5. The fixing screw 28 is arranged transversely. The first bolt 5 is provided with a transverse elongated through-hole, and the elongated slot 29 is located on the outside of the elongated through-hole. The fixing screw 28 passes through the elongated through-hole and is threadedly connected with the adjusting bolt 10, and the head of the fixing screw 28 is disposed in the elongated slot 29.

[0036] In use, after the height of the adjusting bolt 10 is adjusted by the adjusting screw 26, the fixing screw 28 can be rotated to fix the relative height between the adjusting bolt 10 and the first bolt 5 by means of the frictional force from the cooperation between the fixing screw 28 and the elongated slot 29.

[0037] To enable the rotation of the lock cylinder 3 to drive the first bolt 5 and the adjusting bolt 10 to unlock, a first drive block 11 is disposed on the right side surface of the drive part 4, and the rear side surface of the first drive block 11 abuts against the front side surface of a driving block 34 located at the rear end of the first bolt 5.

[0038] Specifically, the driving block 34 is located at the rear left side of the first bolt 5, and its front side surface abuts against the rear side surface of the first drive block 11. When the lock cylinder 3 is rotated with a key, the first drive block 11 can push the first bolt 5 and the adjusting bolt 10 connected thereto to move rearward synchronously through the driving block 34, thereby achieving the unlocking action.

[0039] To achieve the effect of automatic locking, a first spring 24 is disposed at the rear end of the first bolt 5, and the rear side surface of the first spring 24 abuts against the lock housing 1.

[0040] Specifically, a groove for placing the first spring 24 is provided at the lower right corner of the rear end of the first bolt 5, and the rear end of the first spring 24 abuts against the inner wall of the lock housing 1.

[0041] In the unlocked state, the rearward movement of the first bolt 5 compresses the first spring 24. When the lower cover is closed, the lock cylinder 3 rotates back to reset, and the first bolt 5 moves forward to reset under the elastic force of the first spring 24, thereby achieving automatic locking.

[0042] To guide and limit the movement of the first bolt 5, a first limit slot 17 is disposed on the first bolt 5. A limit block 19 is disposed inside the lock housing 1 and cooperates with the first limit slot 17 to limit the stroke of the first bolt 5.

[0043] The limit block 19 is threadedly connected with the lock housing 1, which facilitates maintenance of the lock body, as well as the disassembly, maintenance, and replacement of the first bolt 5.

[0044] To facilitate the replacement of the lock cylinder 3, the drive part 4 is provided with a threaded rod 30 which is threadedly connected with the lock housing 1.

[0045] The drive part 4 is provided with an annular slot 35. The threaded rod 30 is threadedly connected with the lock housing 1, and its inner end extends into the lock housing 1 and cooperates with the annular slot 35, which can limit the lock cylinder 3 in the axial direction and prevent the lock cylinder 3 from coming off. When replacing the lock cylinder 3, the threaded rod 30 is screwed out to separate its inner end from the annular slot 35, and then the lock cylinder 3 can be replaced.

[0046] In this embodiment, the threaded rod 30 is located at the rear side of the drive part 4.

[0047] When unlocking is required, at this time, the lock housing 1 is installed on the lower cover, and the lower side surface of the adjusting bolt 10 is in contact and cooperation with a locking slot of the battery box. The lock cylinder 3 is operated with a key, causing its output end to drive the drive part 4 to rotate. At this time, the first drive block 11 drives the first bolt 5 and the adjusting bolt 10 connected thereto to move rearward, the first bolt 5 and the adjusting bolt 10 are removed from the locking slot of the battery box, thus achieving the unlocking operation.

[0048] The structure of this embodiment is novel, the concept is ingenious, and the operation is simple and convenient. Through this design, the adjustment of the bolt height is effectively facilitated, and the function of adapting to the cooperation clearance of the lock is realized.Embodiment 2

[0049] On the basis of Embodiment 1, this embodiment also provides a structure lock with an adjustable bolt height. The structure of this embodiment is substantially the same as that of Embodiment 1, with the difference being that, an adjusting screw 26 is threadedly connected with the front part of the first bolt 5, and the lower side of the adjusting screw 26 abuts against the adjusting bolt 10.

[0050] The first bolt 5 is provided with a threaded hole at a position above the adjusting bolt 10 in the front part. The adjusting screw 26 is assembled in the threaded hole, and the lower side of the adjusting screw 26 abuts against the adjusting bolt 10.

[0051] By rotating the adjusting screw 26 downward, the adjusting screw 26 can be used to push the adjusting bolt 10 to move downward, thereby adjusting the height of the adjusting bolt 10 relative to the first bolt 5. After the adjusting screw 26 is rotated in the reverse direction, the adjusting spring 32 provides a force for the adjusting bolt 10 to move upward, thereby resetting the height of the adjusting bolt 10.Embodiment 3

[0052] As shown in FIGS. 5-7, on the basis of Embodiment 1, this embodiment also provides a structure lock with an adjustable bolt height. The structure of this embodiment is substantially the same as that of Embodiment 1, with the difference being that, in addition to the first bolt 5 with the adjusting bolt 10, this embodiment is further provided with a second bolt 7 arranged side-by-side with the first bolt 5.

[0053] Specifically, a second bolt 7 capable of moving back and forth is disposed on the right side of the first bolt 5, and the first bolt 5 and the second bolt 7 can be unlocked sequentially.

[0054] To drive the first bolt 5 and the second bolt 7 to unlock sequentially through the rotation of the lock cylinder 3, a first drive block 11 and a second drive block 12 are sequentially disposed on the right side surface of the drive part 4 from left to right. The first bolt 5 is provided with a first assembly slot 36, and the second bolt 7 is provided with a second assembly slot 37. The first drive block 11 cooperates with the first assembly slot 36 and its rear side surface abuts against the rear side inner wall of the first assembly slot 36. The second drive block 12 cooperates with the second assembly slot 37, and a clearance is left between the second drive block 12 and the top inner wall of the second assembly slot 37. After the lock cylinder 3 is rotated, the upper surface of the second drive block 12 abuts against the rear side inner wall of the second assembly slot 37. Through the cooperation of the first drive block 11 with the first assembly slot 36 and the second drive block 12 with the second assembly slot 37, rotating the lock cylinder 3 can drive the first bolt 5 and the second bolt 7 to unlock sequentially.

[0055] The second drive block 12 is a horizontal plate-like structure. When in the locked state, the rear side surface of the first drive block 11 directly abuts against the rear side inner wall of the first assembly slot 36, while a clearance is left between the upper surface of the second drive block 12 and the top inner wall of the second assembly slot 37. When the lock cylinder 3 is rotated to unlock, the first drive block 11 directly drives the first bolt 5 to move rearward. At the same time, the second drive block 12 rotates synchronously until the upper surface of the second drive block 12 rotates to face rearward, i.e., the upper surface abuts against the rear side inner wall of the second assembly slot 37. At this time, the second drive block 12 continues to rotate under the drive of the lock cylinder 3 and then drives the second bolt 7 to move rearward, thereby achieving the effect of sequential unlocking of the first bolt 5 and the second bolt 7.

[0056] To position the rotation of the lock cylinder 3, a positioning pin 38 is disposed on the right side of the second drive block 12. The positioning pin 38 is assembled in an elongated hole 39 on the right side surface of the second bolt 7.

[0057] The elongated hole 39 is located in the front-rear direction. The positioning pin 38 can rotate within the elongated hole 39 along with the lock cylinder 3, and the design of the elongated hole 39 can guide the front-rear movement of the second bolt 7.

[0058] To achieve automatic locking, a first spring 24 is disposed at the rear side of the first bolt 5, and a second spring 25 is disposed at the rear side of the second bolt 7. The rear side surfaces of the first spring 24 and the second spring 25 both abut against the lock housing 1.

[0059] During the process of rotating the lock cylinder 3 to unlock the first bolt 5 and the second bolt 7, the first spring 24 and the second spring 25 are compressed. After the lower cover is closed, the lock cylinder 3 rotates back to reset. The first bolt 5 moves forward to reset under the elastic force of the first spring 24 to achieve automatic locking. Similarly, the second bolt 7 also moves forward to reset under the elastic force of the second spring 25 to achieve automatic locking.

[0060] Preferably, assembly pins 40 are respectively disposed at the rear ends of the first bolt 5 and the second bolt 7. The first spring 24 is installed on the assembly pin 40 at the rear end of the first bolt 5 to position the first spring 24. Similarly, the second spring 25 is installed on the assembly pin 40 at the rear end of the second bolt 7 to position the second spring 25.

[0061] To guide and limit the movement of the bolts, the first bolt 5 is provided with a first limit slot 17, and the second bolt 7 is provided with a second limit slot 18. Two limit blocks 19 are disposed inside the lock housing 1, and the limit blocks 19 cooperate with the first limit slot 17 and the second limit slot 18 respectively to form a structure for limiting the strokes of the first bolt 5 and the second bolt 7.

[0062] Specifically, the first limit slot 17 in this embodiment is provided on the top of the first bolt 5, and the second limit slot 18 is provided on the top of the second bolt 7 and is located between two front-rear opposite stop blocks.

[0063] Similar to Embodiment 1, the limit block 19 is threadedly connected with the lock housing 1, which facilitates maintenance of the lock body, as well as the disassembly, maintenance, and replacement of the bolts. Similarly, in this embodiment, the drive part 4 is provided with a threaded rod 30 threadedly connected with the lock housing 1. The cooperation mode and arrangement position with the drive part 4 are the same as in Embodiment 1.

[0064] Batteries on the market are generally installed in an inverted manner. When the battery box is opened, the batteries will fall out by themselves due to gravity, especially when the operator makes a misoperation, which can easily cause the batteries to fall.

[0065] In this embodiment, by designing the first bolt 5 and the second bolt 7 that open sequentially, and the adjusting bolt 10 with a height adjustment function, not only can the height of the adjusting bolt 10 relative to the first bolt 5 be adjusted to make the adjusting bolt 10 adapt to the tolerance clearance generated during the installation of the lock body, thus increasing the overall applicability of the device, but also the change in the height difference of the bolts after the first bolt 5 is opened can be used to remind the operator, thus reducing the probability of accidental opening by the operator and avoiding the problem of batteries falling.

[0066] In this embodiment, the assembly relationship among the first bolt 5, the adjusting screw 26, and the adjusting bolt 10 adopts the manner in Embodiment 1, and the cooperation manner in Embodiment 2 is also applicable.Embodiment 4

[0067] As shown in FIGS. 8-12, on the basis of Embodiment 3, this embodiment also provides a structure lock with an adjustable bolt height. The structure of this embodiment is substantially the same as that of Embodiment 3, with the difference being that the first bolt and the second bolt in this embodiment are provided with independent unlocking structures respectively, and the first bolt and the second bolt are also unlocked sequentially.

[0068] A structure lock with an adjustable bolt height includes a lock housing 1 and a dust cover 2 that are interconnected. To facilitate the adaptation to the cooperation clearance of the lock, the dust cover 2 is detachably connected with the rear side of the lock housing 1 by bolts. A lock cylinder 3 is disposed inside the lock housing 1. The output end of the lock cylinder 3 is connected with a drive part 4. A first bolt 5 and a connecting rod 6 that move in opposite directions as the drive part 4 rotates are disposed on the right side of the drive part 4. A second bolt 7 capable of moving back and forth is disposed on the right side of the first bolt 5. An unlocking rod 8 capable of moving left and right is disposed inside the dust cover 2. The right side of the unlocking rod 8 is slidably connected with the rear side of the second bolt 7. A locking slot 9 is disposed on the upper side of the unlocking rod 8. The rear end of the connecting rod 6 is slidably connected with the locking slot 9. The connecting rod 6 and the locking slot 9 cooperate with each other to form a structure for sequential unlocking of the first bolt 5 and the second bolt 7. A height-adjustable adjusting bolt 10 is disposed on the front side of the first bolt 5.

[0069] In use, the first bolt 5 and the second bolt 7 need to be opened sequentially. The first bolt 5 is controlled by the lock cylinder 3, and the second bolt 7 is controlled by the unlocking rod 8. The first unlocking controlled by the lock cylinder 3 can effectively remind the operator, reducing the probability of damage to articles caused by accidental unlocking.

[0070] By adjusting the height of the adjusting bolt 10 relative to the first bolt 5, the adjusting bolt 10 can be made to adapt to the tolerance clearance generated during the installation of the lock body, thereby increasing the overall applicability of the device.

[0071] When unlocking is required, at this time, the lock housing 1 is installed on the lower cover, and the lower side surface of the adjusting bolt 10 is in contact and cooperation with the locking slot of the battery box. The lock cylinder 3 is operated with a key, so that the output end of the lock cylinder 3 drives the drive part 4 to rotate. At this time, the first bolt 5 moves rearward, and the connecting rod 6 moves forward. As the first bolt 5 moves rearward, it drives the adjusting bolt 10 to move rearward together. At this time, because the adjusting bolt 10 is at a lower position relative to the second bolt 7, when the adjusting bolt 10 disengages from the locking slot of the battery box, the lock housing 1 moves downward relative to the battery box along with the lower cover. This movement distance is equal to the height difference between the lower side surface of the adjusting bolt 10 and the lower side surface of the second bolt 7. At this time, the second bolt 7 is in contact and cooperation with the locking slot of the battery box, reminding the operator. After the operator confirms that there is no misoperation, the unlocking rod 8 can be pressed. The unlocking rod 8 drives the second bolt 7 to move rearward, thus completely opening the lower cover.

[0072] To increase the reminder function for the operator, a first drive block 11 and a second drive block 12 are fixedly connected with the right side surface of the drive part 4. A first connecting block 13 abuts against the front side of the first drive block 11. The first connecting block 13 is fixedly connected with the front side of the connecting rod 6. The connecting rod 6 is slidably connected with the first bolt 5. A second connecting block 14 abuts against the rear side of the second drive block 12. The second connecting block 14 is fixedly connected with the rear side of the first bolt 5.

[0073] A first slot 15 is disposed in the middle of the first bolt 5. The first connecting block 13 is slidably connected with the first slot 15. A connecting spring 16 is disposed on the front side of the first connecting block 13, and the front side of the connecting spring 16 abuts against the front side surface of the first slot 15.

[0074] The locking slot 9 is in a T shape. A first inclined surface 20 is disposed on the right side surface of the unlocking rod 8. An extension block is fixedly connected with the lower side of the rear end of the second bolt 7. The extension block is located at the rear side of the first inclined surface 20. A return slot 21 is disposed in the middle of the unlocking rod 8. A return spring 22 is disposed on the left side surface of the return slot 21, and the right side surface of the return spring 22 abuts against the dust cover 2. A fixing block is disposed inside the dust cover 2 for pressing against the right side surface of the return spring 22 to provide a force for the unlocking rod 8 to move leftward. The left side of the unlocking rod 8 is connected with an unlocking button 23 by a bolt.

[0075] In use, when the first bolt 5 is in the forward extended state, under the action of the return spring 22, the first connecting block 13 drives the connecting rod 6 to move rearward. At this time, the connecting rod 6 is located at the rearmost part of the locking slot 9, and the unlocking rod 8 is in a locked state and cannot move left or right. When the drive part 4 rotates, the first bolt 5 moves rearward, and at the same time, the connecting rod 6 moves forward. The connecting rod 6 is located at the front part of the locking slot 9, and the unlocking rod 8 can then move left and right. At this time, the operator needs to operate with both hands, one hand operating the key and the other hand pressing the unlocking button 23, which can effectively remind the operator against misoperation.

[0076] To facilitate maintenance of the lock body, a first limit slot 17 is disposed on the first bolt 5, and a second limit slot 18 is disposed on the second bolt 7. Two limit blocks 19 are disposed inside the lock housing 1. The limit blocks 19 cooperate with the first limit slot 17 and the second limit slot 18 respectively to form a structure for limiting the strokes of the first bolt 5 and the second bolt 7.

[0077] In this embodiment, the first limit slot 17 is located on the upper side of the first bolt 5, and the second limit slot 18 is located on the right side of the second bolt 7.

[0078] It should be noted that each limit block 19 is threadedly connected with the lock housing 1, facilitating the disassembly, maintenance, and replacement of the bolts.

[0079] To achieve the effect of direct locking, the first spring 24 abuts against the middle of the first bolt 5, and the second spring 25 abuts against the middle of the second bolt 7. The rear side surfaces of the first spring 24 and the second spring 25 both abut against the lock housing 1. Inclined surfaces are formed on the front sides of the first bolt 5 and the second bolt 7.

[0080] In use, because the first bolt 5 is controlled by the first spring 24 for expansion and retraction, and similarly, the second bolt 7 is controlled by the second spring 25 for expansion and retraction, the first inclined surface 20 on the right side surface of the unlocking rod 8 is located on the front side of the extension block at the rear end of the second bolt 7. Therefore, when the first bolt 5 and the second bolt 7 are pressed backward by an external force, they can both move backward freely. When the lower cover is closed, the first bolt 5 and the second bolt 7 can both move forward under the action of the corresponding springs, thereby locking the lower cover.

[0081] To facilitate the adjustment of the bolt height, the first bolt 5 is threadedly connected with an adjusting screw 26 at the front part. The lower side of the adjusting screw 26 abuts against the adjusting bolt 10. A torsion spring 27 is disposed on the right side surface of the first bolt 5. A slot is formed on the rear side of the adjusting bolt 10. The upper end of the torsion spring 27 abuts against the upper side surface of the slot on the rear side of the adjusting bolt 10.

[0082] In use, by rotating the adjusting screw 26, the adjusting bolt 10 can be pressed downward to adjust the height of the adjusting bolt 10 relative to the first bolt 5. After the adjusting screw 26 is rotated in the reverse direction, the torsion spring 27 provides a force for the adjusting bolt 10 to move upward, thereby resetting the height of the adjusting bolt 10.

[0083] In this embodiment, the torsion spring 27 is used to replace the adjusting spring 32 used in Embodiment 3 to achieve the upward movement of the adjusting bolt 10. Similarly, the torsion spring 27 used in this embodiment and the slot structure cooperating with the torsion spring 27 are also applicable to Embodiments 1, 2, and 3.

[0084] In this embodiment, the assembly relationship among the first bolt 5, the adjusting screw 26, and the adjusting bolt 10 adopts the manner in Embodiment 2, and is also applicable to the cooperation manners disclosed in Embodiments 1 and 3.

[0085] To increase the height stability of the adjusting bolt 10, a fixing screw 28 is threadedly connected with the left side of the adjusting bolt 10. An elongated slot 29 is formed on the left side surface of the first bolt 5. The middle part of the fixing screw 28 cooperates with the elongated slot 29.

[0086] In use, after the height of the adjusting bolt 10 is adjusted by the adjusting screw 26, the fixing screw 28 can be rotated to fix the relative height between the adjusting bolt 10 and the first bolt 5 by means of the frictional force from the cooperation between the fixing screw 28 and the elongated slot 29.

[0087] To facilitate the replacement of the lock cylinder 3, the drive part 4 is provided with a threaded rod 30 threadedly connected with the lock housing 1.

[0088] In this embodiment, the threaded rod 30 is located on the upper side of the rear part of the drive part 4.

[0089] In use, the lock cylinder 3 can be replaced after the threaded rod 30 is removed.

[0090] When the present invention is in use, the first bolt 5 and the second bolt 7 need to be opened sequentially. The first bolt 5 is controlled by the lock cylinder 3, and the second bolt 7 is controlled by the unlocking rod 8. The first unlocking controlled by the lock cylinder 3 can effectively remind the operator, reducing the probability of damage to articles caused by accidental unlocking.

[0091] By adjusting the height of the adjusting bolt 10 relative to the first bolt 5, the adjusting bolt 10 can be made to adapt to the tolerance clearance generated during the installation of the lock body, thereby increasing the overall applicability of the device.

[0092] When unlocking is required, at this time, the lock housing 1 is installed on the lower cover, and the lower side surface of the adjusting bolt 10 is in contact and cooperation with the locking slot of the battery box. The lock cylinder 3 is operated with a key, so that the output end of the lock cylinder 3 drives the drive part 4 to rotate. At this time, the first bolt 5 moves rearward, and the connecting rod 6 moves forward. As the first bolt 5 moves rearward, it drives the adjusting bolt 10 to move rearward together. At this time, because the adjusting bolt 10 is at a lower position relative to the second bolt 7, when the adjusting bolt 10 disengages from the locking slot of the battery box, the lock housing 1 moves downward relative to the battery box along with the lower cover. This movement distance is equal to the height difference between the lower side surface of the adjusting bolt 10 and the lower side surface of the second bolt 7. At this time, the second bolt 7 is in contact and cooperation with the locking slot of the battery box, thus reminding the operator. After the operator confirms that there is no misoperation, the unlocking rod 8 can be pressed. The unlocking rod 8 drives the second bolt 7 to move rearward, thus completely opening the lower cover.

[0093] The structure of this embodiment is novel, the concept is ingenious, and the operation is simple and convenient. Through this design, the adjustment of the bolt height is effectively facilitated, and the function of adapting to the cooperation clearance of the lock is realized. It improves the reminder function for the operator by requiring two unlocking actions, facilitates maintenance of the lock body, and achieves the effect of direct locking, thus increasing the height stability of the adjusting bolt 10.Embodiment 5

[0094] As shown in FIG. 13, on the basis of Embodiment 4, this embodiment also provides a structure lock with an adjustable bolt height. The structure of this embodiment is substantially the same as that of Embodiment 4, with the difference being that this embodiment adopts the structures in Embodiments 1 and 2, i.e., the component for pushing the adjusting bolt 10 to move upward is the adjusting spring 32.

[0095] Specifically, the first bolt 5 is provided with an accommodating cavity 31 with an opening facing upward. An adjusting spring 32 is installed in the accommodating cavity 31. A top rear side of the adjusting bolt 10 is provided with a protrusion 33 covering the top of the accommodating cavity 31. The upper end of the adjusting spring 32 abuts against the protrusion 33.

[0096] In this embodiment, the adjusting spring 32 is used to replace the function of the torsion spring 27 in Embodiment 4. That is, in use, by rotating the adjusting screw 26, the adjusting bolt 10 can be pressed downward to adjust the height of the adjusting bolt 10 relative to the first bolt 5. After the adjusting screw 26 is rotated in the reverse direction, the adjusting spring 32 provides a force for the adjusting bolt 10 to move upward, thereby resetting the height of the adjusting bolt 10.

[0097] For the cooperation relationship among the first bolt 5, the adjusting bolt 10, and the adjusting screw 26, the manners in Embodiments 1 and 2 are both applicable.

[0098] Based on the ideal embodiments of the present invention, those of ordinary skill can make various changes and modifications without departing from the scope of the technical idea of the present invention through the above description. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
