[0001] This utility model relates to the field of smart lock technology, specifically a lock body structure that is easy to assemble and disassemble. Background Technology
[0002] Smart locks are improvements on traditional mechanical locks, offering greater intelligence and convenience in terms of security, identification, and management. The lock body of a smart lock includes an inner lock body and an outer lock body installed on both the inside and outside of the door.
[0003] The smart lock body is equipped with a battery pack. The batteries are divided into two types: detachable and non-detachable. When detachable batteries are installed and removed from the inner lock body, they need to be used with a protective cover. Traditional protective covers are often installed by snap-fit. For example, the Chinese utility model disclosure CN221298838U discloses a lock body structure that is easy to install and remove. The cover is locked to the lock body through a lock box assembly. However, this structure cannot stably lock the cover and is easily detached by external impact (children at home or scratches), causing the lock body structure to lose power. Using bolts for locking makes installation and removal inconvenient. Therefore, there is a need for a lock body structure that is both easy to install and remove and structurally stable. Utility Model Content
[0004] The purpose of this utility model is to provide a lock body structure that is easy to assemble and disassemble. The locking component can stably lock the protective cover plate to the lock body, while preventing it from falling off due to external force. At the same time, the snap-fit structure connects the protective cover plate to the lock body structure, preventing the protective cover plate from sliding off directly when removed. It can also limit the protection of the portable battery by the protective cover plate, thus protecting the safety of the portable battery. In addition, the locking component is easy for adults to operate, effectively preventing children from accidentally operating it, thereby solving the problems mentioned in the background art.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] This utility model provides, for example Figures 1-7 The lock body structure shown is easy to assemble and disassemble, comprising:
[0026] Lock body 1 installed on the inside of the door;
[0027] The lock body 1 is provided with a battery mounting cavity 2, a movable battery 3 is installed in the battery mounting cavity 2, and a protective cover plate 4 is also installed in the battery mounting cavity 2 to protect the movable battery 3. A snap-fit structure 5 is provided between the top of the protective cover plate 4 and the lock body 1. A locking component 6 is provided on the lock body 1 to lock the bottom of the protective cover plate 4. A display screen is also embedded on the lock body 1. The display screen is connected to the camera on the external lock body of the smart lock. At the same time, a deadbolt knob is provided at the lower end of the lock body 1.
[0028] The top of the protective cover 4 is snapped into the battery mounting cavity 2 by the snap-fit structure 5, which can also limit the fall of the protective cover 4. Then, the bottom of the protective cover 4 is locked by the locking component 6. Since the locking structure uses a rigid connection between the turntable 62 and the limiting groove 65 for locking, the stability of the protective cover 4 can be maintained. At the same time, the operation of the locking component 6 can also prevent children from accidentally opening it, which is both safe and easy to disassemble and assemble.
[0029] Among them, such as Figure 3 and Figure 6 As shown:
[0030] The snap-fit structure 5 includes storage slots 51 on both sides of the top of the battery mounting cavity 2, and elastic buckles 52 are fixedly installed in the inner cavity of the storage slots 51. Inserts 53 are fixed on both sides of the top of the protective cover plate 4. The inserts 53 snap into the inner side of the elastic buckles 52. When the inserts 53 are inserted into the elastic buckles 52, the inserts 53 first squeeze the elastic buckles 52 to open to both sides, and then the inserts 53 are inserted. Then the elastic buckles 52 elastically recover and restrict the inserts 53. This mechanism can prevent the upper end of the protective cover plate 4 from falling off after the bottom of the protective cover plate 4 is removed from the battery mounting cavity 2 by the elastic buckles 52.
[0031] Furthermore, such as Figure 2-5 As shown:
[0032] The locking assembly 6 includes a chamber 61 located inside the lock body 1, below and communicating with the battery mounting cavity 2. A notched turntable 62 is movably disposed within the chamber 61. A connecting post 63 is fixed at the center of the turntable 62. One end of the connecting post 63 extends outward and is fixed with a rotating seat 64. A limiting groove 65, which mates with the turntable 62, is provided at the bottom of the protective cover plate 4. A groove 66 is annularly formed on the outer side of the turntable 62. A protrusion 67, which engages with the groove 66, is annularly fixed at the rear end of the inner wall of the limiting groove 65. A support spring 68 is sleeved on the outer side of the connecting post 63. One end of the support spring 68 is fixed to one end of the turntable 62, and the other end is fixed to a part sleeved on the outer side of the connecting post 63. The washer ring 69 is attached to the front end of the chamber 61 and is supported by the support spring 68. The turntable 62 is moved backward in the limiting groove 65, so that the protrusion 67 in the limiting groove 65 engages with the groove 66 on the turntable 62, restricting the rotation of the turntable 62 in the limiting groove 65. This is used to lock the protective cover plate 4 by engaging the turntable 62 in the limiting groove 65. When the rotating seat 64 is moved outward, the turntable 62 moves forward in the limiting groove 65, realizing the separation of the protrusion 67 and the groove 66. At this time, the rotating seat 64 can be rotated, and the turntable 62 can be rotated through the connecting column 63, realizing the rotation of the turntable 62 in the chamber 61 and the limiting groove 65. The notch on the turntable 62 contacts the protective cover plate 4 and the lock body 1 for locking.
[0033] Preferred, such as Figure 2-3 As shown:
[0034] Positioning blocks 7 are fixed at the rear ends of the top two sides of the protective cover plate 4. Corresponding positioning grooves 8 are provided on both sides of the top of the battery mounting cavity 2. The cooperation between the positioning blocks 7 and the positioning grooves 8 ensures the stability of the position of the protective cover plate 4 when it is placed in the battery mounting cavity 2, and at the same time makes the outer side of the protective cover plate 4 flush with the outer side of the lock body 1.
[0035] It is worth noting that, such as Figure 7 As shown:
[0036] Two sets of holes are provided at the lower end of the back of the battery mounting cavity 2. An elastic piece 9 is fixed inside the hole. A top post 10 is movably installed inside the hole. One end of the top post 10 abuts against the elastic piece 9, and the other end of the top post 10 extends into the battery mounting cavity 2 and abuts against the protective cover plate 4. The top post 10 is supported by the elastic piece 9. After the top post 10 moves out of the hole, it pushes the protective cover plate 4, so that the lower end of the protective cover plate 4 can be lifted and moved out of the battery mounting cavity 2.
[0037] In a further preferred embodiment, such as Figure 4-5 As shown:
[0038] A limiting post 11 is fixed at the center of the back of the chamber 61. The front end of the limiting post 11 slides through the interior of the connecting post 63. The limiting post 11 is used to maintain the stability of the connecting post 63 and prevent the connecting post 63 from shaking, which would cause the turntable 62 to shake and prevent the protrusion 67 from engaging with the groove 66, thus affecting the locking effect of the turntable 62 on the protective cover plate 4.
[0039] In practical use, when it is necessary to remove the movable battery 3, the protective cover 4 must first be removed. At this time, the rotating seat 64 needs to be pinched and moved outward. The rotating seat 64 drives the turntable 62 to move from back to front in the limiting groove 65 through the connecting column 63, so that the protrusion 67 in the limiting groove 65 separates from the groove 66 on the turntable 62. The turntable 62 can rotate freely at the front end of the limiting groove 65. Then rotate the rotating seat 64, and the turntable 62 is moved out of the limiting groove 65 through the connecting column 63. At this time, the lower end of the protective cover 4 is locked, and the elastic piece 9 supports the top column 10, so that the bottom of the protective cover 4 is lifted and moved out of the battery mounting cavity 2. Then the operator holds the protective cover 4 and removes the plug 53 from the elastic piece. Pull out the clip 52 and then remove the mobile battery 3. When the protective cover 4 needs to be installed, first insert the plug 53 at the top of the protective cover 4 into the inner side of the elastic clip 52 in the storage groove 51, and at the same time insert the positioning block 7 into the positioning groove 8. Then press the lower end of the protective cover 4 so that the entire protective cover 4 is placed in the battery installation cavity 2. The protective cover 4 is squeezed by the top post 10 to make the top post 10 retract into the hole. Pull the rotating seat 64 forward, and then rotate the rotating seat 64 so that the turntable 62 rotates from the cavity 61 into the limiting groove 65. Then the support spring 68 drives the turntable 62 to move backward so that the protrusion 67 engages with the groove 66 to limit the rotation of the turntable 62, thus completing the installation of the protective cover 4.
