[0021] The standard parts used in this utility model can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional methods such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0022] The following is combined with Figure 1-4 , further details of this application are given.

[0023] This application provides a smart door lock connection structure that can adapt to different door panel thicknesses, using the following technical solutions:

[0024] Example 1

[0025] Reference Figure 1 and Figure 2The connection structure includes two lock bodies 1, a square rod 2, a movable sleeve 3, and a stopper 4. The two lock bodies 1 are mounted on opposite sides of the door panel. Connecting posts are rotatably mounted on opposing sides of each lock body 1. These posts have square holes 11 formed in them. The connecting posts are linked to the handles of the lock bodies 1, and rotation of the handles drives the connecting posts to rotate. The lock bodies in this embodiment are any commercially available lock bodies. The square rod 2 and movable sleeve 3 are mounted between the two lock bodies 1. The movable sleeve 3 is a hollow square tube that matches the shape of the square rod 2. It is worth noting that both the square rod 2 and movable sleeve 3 are of conventional specifications that are commercially available. Specifically, in this embodiment, the length of the square rod 2 is 80 mm, and the length of the movable sleeve 3 is 60 mm. One end of the square rod 2 is inserted into the square hole 11 of one lock body 1, while one end of the movable sleeve 3 is inserted into the square hole 11 of the other lock body 1. The movable sleeve 3 is sleeved onto the end of the square rod 2 away from the lock body 1, and the movable sleeve 3 slides back and forth along the length of the square rod 2. The stopper 4 is mounted on the end of the square rod 2 away from the lock body 1. The stopper 4 can prevent the movable sleeve 3 from sliding relative to the square rod 2. When the stopper 4 locks the square rod 2 and the movable sleeve 3 at their maximum overlap, the distance between the two lock bodies 1 is the shortest. When the stopper 4 locks the square rod 2 and the movable sleeve 3 at their minimum overlap, the distance between the two lock bodies 1 is the longest. Through the relative sliding between the square rod 2 and the movable sleeve 3 and the locking and tightening of the stopper 4, the square rod 2 and the movable sleeve 3 can be combined into a variety of length specifications between the maximum and minimum overlap lengths of the square rod 2 and the movable sleeve 3. This further diversifies the distance between the two lock bodies 1, thereby adapting to door panels of different thicknesses and thereby increasing the adaptability of the smart door lock connection structure to door panels.

[0026] In the preferred embodiment of the present application, referring to Figure 1 and Figure 2 The stopper 4 is a spring pin 41, embedded and mounted on the circumference of the end of the square rod 2. The movable sleeve 3 is provided with at least two positioning holes 31. The spring pin 41 is aligned and inserted into one of the positioning holes 31. Each positioning hole 31 corresponds to a length specification of the square rod 2 and movable sleeve 3 combination. In this embodiment, two positioning holes 31 are provided. In actual production, the number and spacing of positioning holes 31 are set according to the needs of the user group, resulting in a variety of length specifications for the square rod 2 and movable sleeve 3 combination, thereby adapting to the needs of door panels of different thicknesses.

[0027] Further, refer to Figure 1 and Figure 2The diameter of the positioning hole 31 is larger than that of the spring pin 41. When the spring pin 41 is inserted into the positioning hole 31, it can move slightly radially along the positioning hole 31. In this embodiment, the range of movement is 0 to 0.5 mm. This increases the floating space of the combined length specifications of the square rod 2 and the movable sleeve 3, improving the compatibility of the smart door lock connection structure with door panels of varying thicknesses. Furthermore, a support spring 5 is sleeved and mounted on the circumference of the square rod 2. The support spring 5 is a square spring. The end of the square rod 2 near the lock body 1 is integrally connected to a mounting portion 21. The mounting portion 21 matches the square hole 11 in the lock body 1 and is inserted into the square hole 11. One end of the support spring 5 abuts the end surface of the mounting portion 21, and the other end abuts the end surface of the movable sleeve 3. The natural length of the support spring 5 is greater than the length of the square rod 2. When the support spring 5 is assembled on the circumference of the square rod 2, the support spring 5 is always in a compressed state. The movable sleeve 3 is pushed away from the mounting portion 21 by the restoring elastic force of the support spring 5 , thereby driving the positioning pin to press against the inner wall of the positioning hole 31 , thereby enhancing the stability of the limiting member 4 .

[0028] Example 2

[0029] The difference from Example 1 is that Figure 3 The stopper 4 is an adjustment screw 42, threadedly connected to the circumference of the end of the square rod 2. The movable sleeve 3 is provided with an elongated, waist-shaped hole 32, extending along the length of the square rod 2. The adjustment screw 42 is inserted into the waist-shaped hole 32. Loosening the adjustment screw 42 relative to the side of the square rod 2 allows it to slide relative to the movable sleeve 3 along the length of the waist-shaped hole 32, thereby freely adjusting the combined length of the square rod 2 and movable sleeve 3. Tightening the adjustment screw 42 relative to the side of the square rod 2 allows it to firmly abut the circumference of the movable sleeve 3, restricting its movement relative to the square rod 2 and locking it in place. By varying the position of the adjustment screw 42 within the waist-shaped hole 32, the overlap between the square rod 2 and movable sleeve 3 can be adjusted to accommodate varying door panel thicknesses.

[0030] Example 3

[0031] The difference from Example 1 is that Figure 4The end of the movable sleeve 3 away from the square rod 2 can be detachably connected to the combined sleeve 6. The combined sleeve 6 includes a plurality of combined units 61. Each combined unit 61 has the same shape as the movable sleeve 3 and is a hollow square tube. The length specifications of the combined unit 61 include at least 1mm, 2mm and 5mm. In this embodiment, the length specification of the combined unit 61 is 1mm. A connecting portion 62 is integrally formed at one end of the combined unit 61, and a connecting hole 63 is opened at the other end of the combined unit 61. The shape of the connecting portion 62 matches the shape of the connecting hole 63. When two adjacent combined units 61 are docked, the connecting portion 62 on one combined unit 61 is plugged into the connecting hole 63 on the other combined unit 61. Multiple combined units 61 can be connected end to end according to this step to form a combined sleeve 6. According to the units digit of the door panel thickness, a certain number of combination units 61 are spliced ​​together to form a combination sleeve 6 with a length equal to the last digit of the door panel thickness. The combination sleeve 6 is installed at the end of the movable sleeve 3, and the length of the square rod 2 and the movable sleeve 3 are supplemented. Therefore, the length of the square rod 2 and the movable sleeve 3 only needs to adapt to the overall length of the tens and hundreds digits of the door panel. This reduces the difficulty of adjusting the length of the square rod 2 and the movable sleeve 3, making the smart door lock connection structure more flexible to adjust, thereby adapting to door panels of different thicknesses. In addition, the movable sleeve 3 has a mounting hole 33 on the side of the end away from the square rod 2. The shape of the mounting hole 33 is the same as that of the connecting hole 63. The connecting portion 62 can be inserted into the mounting hole 33, thereby realizing a detachable connection between the combination sleeve 6 and the movable sleeve 3.

Therefore, the present invention is not limited to the specific embodiments described above. Any obvious improvements, substitutions, or modifications made by those skilled in the art based on the present invention fall within the scope of protection of the present invention. In addition, although certain specific terms are used in this description, these terms are for convenience only and do not constitute any limitation on the present invention.
