Description

Technical Field

[0001] This invention relates to the field of smart door lock technology, and more specifically to a smart door lock that can be installed quickly. Background Technology

[0002] Smart locks are locks that offer greater intelligence and convenience in terms of user security, identification, and management. They utilize advanced technologies such as magnetic cards, RFID cards, fingerprint locks, and iris recognition to replace traditional mechanical locks. The main advantages of smart locks include high security, ease of use, and convenient management.

[0003] Smart door locks are widely used in smart home, smart hotel / hotel, smart building and other systems, especially in places where security and convenient management are important, such as banks, government departments, hotels, school dormitories, residential communities, villas and hotels.

[0004] Currently, during the installation of smart locks, the front and rear panels need to be aligned with the square steel of the lock cylinder. However, as the front and rear panels get closer to the door panel, the gap between them and the door panel becomes very narrow, making it impossible to see the position of the square steel. This results in the front and rear panels not being aligned with the square steel, affecting installation efficiency. Furthermore, the square steel may rotate, further affecting the connection with the smart lock. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a smart door lock that can be installed quickly. The front panel, rear panel and square steel of the smart door lock can be positioned by the positioning cavity and the positioning plate, so as to solve the problems mentioned in the background art.

That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a quick-installation smart door lock of the present invention includes a front panel 2 and a rear panel 3. A square steel is installed between the front panel 2 and the rear panel 3. A positioning frame 1 is fitted on the outside of both the front panel 2 and the rear panel 3. A connecting plate 7 is provided between the positioning frames 1 to clamp and fix the positioning frames 1 to the door panel. An adjustment groove 12 is provided on the inner side of the connecting plate 7. An adjustment block is installed on one side of each positioning frame 1. The adjustment blocks are slidably disposed in the adjustment groove 12. A positioning plate 8 is provided at the lower end of the connecting plate 7. A positioning groove 14 is provided at one end of the positioning plate 8. One end of the positioning plate 8 is fitted onto the square steel through the positioning groove 14.

[0026] In this embodiment, the end of the positioning frame 1 away from the connecting plate 7 is open. The top and bottom surfaces of the positioning frame 1 are provided with slots, and insert plates 4 are inserted into the slots. The insert plates 4 and the positioning frame 1 form a positioning cavity that matches the front panel 2 or the rear panel 3 of the smart lock. The outer side of the front panel 2 and the rear panel 3 of the smart lock contacts the inner side of the positioning cavity. Pull plates 5 are installed on the opposite end face of the insert plates 4. Multiple compression springs 6 are installed between the pull plates 5 and the positioning frame 1.

[0027] In this embodiment, a first limiting groove 16 is provided on one side of the insert plate 4, and a first limiting strip 17 is installed on the inner wall of the slot. The first limiting strip 17 is slidably disposed in the first limiting groove 16, and the cross sections of the first limiting strip 17 and the first limiting groove 16 are both trapezoidal.

[0028] In this embodiment, a second limiting groove 18 is provided on the bottom surface of the connecting plate 7, and a second limiting strip 15 is installed on the top surface of the positioning plate 8. The second limiting strip 15 is slidably disposed in the second limiting groove 18. The cross-sections of the second limiting strip 15 and the second limiting groove 18 are both trapezoidal. An L-shaped plate 10 is installed on the top surface of the positioning plate 8. A groove matching the width of the connecting plate 7 is formed between the L-shaped plate 10 and the positioning plate 8. The groove is fitted onto the outside of the connecting plate 7. Multiple locking blocks 19 protrude from the inner side of the L-shaped plate 10. Multiple locking slots are provided on the outer side of the connecting plate 7. The locking blocks 19 are all inserted into the locking slots and are locked and fixed with the locking slots.

[0029] In this embodiment, one end of the adjusting block is provided with a lead screw hole that passes through the adjusting block, and both ends of the connecting plate 7 are provided with mounting holes opposite to the lead screw holes. Sealed bearings are installed in the mounting holes, and lead screws 13 are threadedly connected in the corresponding lead screw holes. Both ends of the lead screws 13 are installed in the inner rings of the sealed bearings, and one end of the lead screws 13 extends outward and is equipped with a handwheel 9.

[0030] The lead screw is divided at the middle, and the threads at both ends of the lead screw are set oppositely, so that after the lead screw rotates, it can drive the adjusting block to move inward or outward synchronously along the adjusting groove.

[0031] In this embodiment, the positioning frame 1, the connecting plate 7, and the adjusting block are all made of metal, which increases their robustness and service life.

[0032] In this embodiment, a groove (not shown) is provided on one side of the positioning frame 1 opposite the positioning plate 8 for the positioning plate 8 to enter, so that the positioning plate can enter the groove.

[0033] In this embodiment, the depth of the positioning cavity is greater than the thickness of the front panel 2 or the rear panel 3 of the smart lock, so that the front panel 2 or the rear panel 3 of the smart lock can move along the positioning cavity.

[0034] During installation, simply rotate the handwheel. The rotation of the handwheel drives the adjusting block, causing it to move inward along the adjusting groove. The movement of the adjusting block drives the positioning frame, allowing it to clamp and fix onto the door panel. The positioning plate extends through the groove on the positioning frame into the interior of the positioning cavity and is fitted onto the square steel through the positioning groove. Multiple support parts protrude from the opposite surfaces of the positioning frame, allowing these support parts to press against the door panel. The support parts prevent complete contact between the positioning frame and the door panel, thus avoiding interference with the insertion of the positioning plate.

[0035] After the above is completed, the front panel and rear panel of the smart lock can be inserted into the positioning cavity, allowing them to move inward along the inner side of the positioning cavity until the slots on the front and rear panels are precisely fitted onto the square steel. Specifically, when the front panel is close to the door panel and the square steel is inserted into the slot (not fully inserted), the L-shaped plate can be pulled outward. The movement of the L-shaped plate moves the positioning plate, allowing it to move out of the positioning cavity and preventing it from interfering with the closing of the front panel.

[0036] After installation, the insert plate can be pulled outward by the pull plate. After the insert plate moves out of the inside of the positioning frame, the handwheel can be rotated in the opposite direction to make the adjusting block and the positioning frame open outward synchronously, so that it can no longer be clamped and fixed to the door panel, and the positioning frame can be directly detached from the front panel and the rear panel of the smart door lock.

[0037] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
