TECHNICAL FIELD

[0001] The present application relates to the technical field of door lock, in particular to a lockset. BACKGROUND

However, in some scenarios, when the door body is installed on the wall, one side of the door frame is adjacent to the solid wall, and the gap between the door frame and the wall is often very limited, so that the transverse movement range of the handle is limited, thereby increasing the risk of collision between the handle and the wall.

[0016] In some embodiments, when the sleeve portion moves along the axial direction of the rotation axis to the protruding portion contacting the limit protrusion, the first limit portion is at least partially located between the second limit portion and the third limit portion along the axial direction of the rotation axis.

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0041] In some related technologies, there are doors where one side of the door frame is a solid wall with a small gap between the door frame and the handle. This limits the space for the handle to move laterally and increases the risk of it hitting the wall.

[0042] If the length of the lock box is along the height of the door, and the handle is also initially extended along the height of the door, then if one side of the door frame is a solid wall, the free end of the handle will have a wide path range when the handle is turned, making it easy to collide with the wall.

[0043] To solve the above-mentioned technical problems, this application proposes a lock, including a lock box 100, a rotating shaft 200, and a handle assembly 300. By adjusting the installation position of the handle assembly 300 relative to the rotating shaft 200, the installation position of the handle assembly 300 relative to the lock box 100 can be adjusted, thereby adjusting the space for movement of the handle assembly 300 and reducing the probability of hitting the wall.

[0044] Please refer to the following. Figures 1-2 This further explains the lock in the embodiments of this application.

[0045] The lock housing 100 houses key components such as springs and lock cylinders. It provides a sealed space to protect these components from external environmental factors like dust, moisture, and corrosion, ensuring proper operation and extending the lock's lifespan. For fingerprint and combination locks, the lock housing 100 can also house circuit boards, batteries, and other electrical components. To protect these internal components and ensure material strength, the lock housing 100 can be made of hard materials such as aluminum alloy or stainless steel. Alternatively, other materials with high structural strength, such as plastic, can also be used.

[0046] The lock box 100 is usually designed with mounting holes 200b or fixing devices to facilitate the installation of the lock on the door, cabinet door or other objects that need to be locked. The lock box 100 is designed to be located on the left or right side of the door to meet the user's door opening habits.

[0047] See Figures 3-4The rotating shaft 200 is rotatably mounted on the lock box 100. At least three limiting protrusions 210 are provided on the outer periphery of the rotating shaft 200. The at least three limiting protrusions 210 are arranged at intervals along the circumference of the rotating shaft 200. A limiting groove 210a is formed between two adjacent limiting protrusions 210. The handle assembly 300 includes a handle body 310 and a sleeve part 320 connected to the handle body 310. The sleeve part 320 is sleeved on the rotating shaft 200. At least three positioning protrusions 321 are provided on the inner side wall of the sleeve part 320. The at least three positioning protrusions 321 are arranged at intervals along the circumference of the sleeve part 320. A positioning groove 321a is formed between two adjacent positioning protrusions 321.

[0048] The positioning protrusion 321 and the limiting protrusion 210 play a pre-positioning role. By inserting the positioning protrusion 321 into different limiting grooves 210a and the limiting protrusion 210 into the corresponding positioning groove 321a, the installation position of the handle assembly 300 relative to the rotating shaft 200 can be adjusted, that is, the installation position of the handle assembly 300 relative to the lock box 100 can be adjusted. In this way, the space for the movement of the handle assembly 300 can be adjusted, reducing the probability of hitting the wall.

[0049] During normal use of the lock, the positioning protrusion 321 is located in the limiting groove 210a, the limiting protrusion 210 is located in the positioning groove 321a, and the sleeve part 320 and the rotating shaft 200 are kept relatively fixed through the connector 400. If screws or bolts are used for connection, the handle assembly 300 is in the locked state. When it is necessary to change the position of the handle assembly 300, the screws or bolts are removed, so that the handle assembly 300 is in the unlocked state. Then the sleeve part 320 can slide relative to the rotating shaft 200 along the axial direction of the rotating shaft 200, so that the positioning protrusion 321 can be disengaged from the limiting groove 210a, making it easy for the positioning protrusion 321 to be inserted into another limiting groove 210a, so as to realize the position change of the handle assembly 300.

[0050] Please see Figure 4 In one embodiment of this application, a first limiting part 322 is provided on the inner sidewall of the sleeve part 320, and a second limiting part 220 and a third limiting part 230 are provided on the outer sidewall of the rotating shaft 200. The second limiting part 220 and the third limiting part 230 are located on the rotation trajectory of the rotating shaft 200 and are respectively located on both sides of the first limiting part 322.

[0051] When the sleeve portion 320 rotates relative to the rotation axis 200 along the first direction M until the first limiting portion 322 abuts against the second limiting portion 220, the second limiting portion 220 prevents the sleeve portion 320 from rotating along the first direction M.

[0052] When the socket 320 rotates relative to the rotation axis 200 along the second direction N until the first limiting part 322 abuts against the third limiting part 230, the third limiting part 230 prevents the socket 320 from rotating along the second direction N. The first direction M is opposite to the second direction N.

[0053] When the handle assembly 300 is in the unlocked state, after the socket 320 rotates to a certain angle along the first direction M, the first limiting part 322 will abut against the second limiting part 220, thereby positioning the socket 320. Then, along the axial direction of the rotation axis 200, the positioning protrusion 321 can also accurately enter the limiting groove 210a.

[0054] Similarly, after the socket 320 rotates to a certain angle along the second direction N, the first limiting part 322 will abut against the third limiting part 230, thereby positioning the socket 320. Then, along the axial direction of the rotation axis 200, the positioning protrusion 321 can also accurately enter the limiting groove 210a.

[0055] This means that the positioning protrusion 321 and the limiting groove 210a can be accurately matched without the user needing to align them, which greatly improves the efficiency of the position switching of the handle assembly 300.

[0056] Please refer to Figure 2 When the first limiting part 322 rotates along the first direction M to abut against the second limiting part 220, the handle assembly 300 can be set to the first position. In this position, the handle body 310 is set at an angle to the length direction of the lock box 100. This angle is the first angle. The free end of the handle body 310 is located on the first side of the lock box 100.

[0057] When the first limiting part 322 rotates along the second direction N to abut against the second limiting part 220, the handle assembly 300 can be set to the second position. In this position, the handle body 310 is set at an angle to the length direction of the lock box 100. This angle is the first angle. The free end of the handle body 310 is located on the second side of the lock box 100.

[0058] For example, the first direction M can be counterclockwise, with the first side being the left side of the lock box 100, and the second direction N is clockwise, with the second side being the right side of the lock box 100. In this way, the lock box 100 in this embodiment can adapt to the situation where the door opens to the left or right, and has a wider range of applications.

[0059] From the user's perspective outside the door, if the door opens to the left, the lock box 100 is located on the left side of the door. At this time, the handle assembly 300 can be adjusted to the second position, that is, the free end of the handle body 310 is located on the right side of the lock box 100. In this way, the handle assembly 300 has enough room to move and is unlikely to collide with the wall on the left.

[0060] Similarly, when the door is opened to the right, the lock box 100 is located on the right side of the door. At this time, the handle assembly 300 can be adjusted to the first position, that is, the free end of the handle body 310 is located on the left side of the lock box 100. In this way, the handle assembly 300 has enough room to move and is unlikely to collide with the wall on the right.

[0061] Based on the previous embodiment, when the handle assembly 300 is in the first position or the second position, the handle body 310 and the lock box 100 have a first angle in the length direction. The length direction of the lock box 100 can refer to the height direction of the door or the length direction of the door. The handle body 310 and the lock box 100 have a first angle A in the length direction. A satisfies 30°≤A≤120°, that is, A can be any two sets of values ​​between 30°, 50°, 70°, 90°, 120° or more. Within this range, the handle assembly 300 has sufficient room to move, so the handle assembly 300 is unlikely to come into contact with the wall.

[0062] Preferably, A is 90°. In this case, when the handle assembly 300 is in the first position, it corresponds to the "left-mounted" handle. When the handle assembly 300 is in the second position, it corresponds to the "right-mounted" handle. In this way, the entire lock looks neater and conforms to the user's unlocking habits.

[0063] Please see Figures 5-6 In one embodiment of the application, at least three limiting protrusions 210 include a first limiting protrusion 211 and a second limiting protrusion 212. The end of the first limiting protrusion 211 facing away from the rotation axis 200 forms a second limiting portion 220, and the end of the second limiting protrusion 212 facing away from the rotation axis 200 forms a third limiting portion 230.

[0064] That is, there is no need to occupy space on the side wall of the rotating shaft 200 to arrange the first limiting part 322 and the second limiting part 220, so that there is enough space on the side wall of the rotating shaft 200 to arrange multiple limiting protrusions 210, that is, more limiting protrusions 210 can extend into the positioning groove 321a, thereby increasing the stability of the handle assembly 300 when rotating.

[0065] Please see Figures 3-4In another embodiment of the application, along the axial direction of the rotation axis 200, the handle assembly 300 has a first preset position and a second preset position. When the handle assembly 300 is in the first preset position, the positioning protrusion 321 is inserted into the limiting groove 210a. When the handle assembly 300 is in the second preset position, the positioning protrusion 321 and the limiting groove 210a are spaced apart along the axial direction of the rotation axis 200, and the first limiting portion 322 is at least partially located between the second limiting portion 220 and the third limiting portion 230 on both sides along the axial direction of the rotation axis 200.

[0066] Along the circumference of the rotation axis 200, the distance between the two sides of the second limiting part 220 and the distance between the two sides of the third limiting part 230 may be the same or different. In this embodiment, the distance between the two sides of the second limiting part 220 and the distance between the two sides of the third limiting part 230 may be the same, and the side of the second limiting part 220 away from the lock box 100 is flush with the side of the third limiting part 230 away from the lock box 100.

[0067] When the handle assembly 300 is in the first preset position, the positioning protrusion 321 is inserted into the limiting groove 210a, and the positioning protrusion 321 can abut against the limiting protrusion 210 to restrict the rotation of the sleeve portion 320. When the handle assembly 300 is in the second preset position, the positioning protrusion 321 separates from the limiting protrusion 210, and the sleeve portion 320 can rotate relative to the rotation axis 200. Since the first limiting portion 322 abuts against the second limiting portion 220 in the first position, and the first limiting portion 322 abuts against the third limiting portion 230 in the second position, the second limiting portion 220 and the third limiting portion 230... All 0 are within the rotation trajectory of the first limiting part 322, that is, along the axial direction of the rotation axis 200. The first limiting part 322 is at least partially located between the two sides of the second limiting part 220 along the axial direction of the rotation axis 200, and at the same time, the first limiting part 322 is at least partially located between the two sides of the third limiting part 230 along the axial direction of the rotation axis 200. In this way, when the handle assembly 300 is in the second preset position, rotating the sleeve part 320 can cause the first limiting part 322 to abut against the second limiting part 220, or the first limiting part 322 to abut against the third limiting part 230, so as to achieve fast and accurate positioning.

[0068] It is understandable that, in both the "left-mounted" and "right-mounted" states of the handle, the handle assembly 300 needs to rotate in the same direction to open the lock cylinder. To improve the stability of the handle assembly 300 during rotation, this embodiment of the application describes the door as "right-opening," the lock box 100 as installed on the right side of the door, and the handle assembly 300 as opening the lock cylinder by rotating clockwise. In this example, the free end of the handle body 310 is located on the left side of the lock box 100. Since the sleeve portion 320 rotates along the first direction M, i.e., counterclockwise, to the first limiting portion 3... The first limiting part 322 abuts against the second limiting part 220. Since the handle assembly 300 needs to be rotated clockwise to open the lock cylinder, in order to improve the stability of the handle assembly 300 when opening the lock cylinder, the first limiting part 322 and the adjacent positioning protrusion 321 form a groove. When the sleeve part 320 rotates counterclockwise until the first limiting part 322 and the second limiting part 220 abut against each other, when the sleeve part 320 is pressed towards the lock box 100, the second limiting part 220 can extend into the groove and fit against the two side walls of the groove, thereby improving the stability when unlocking.

[0069] It is understandable that when the socket 320 rotates counterclockwise until the first limiting part 322 and the second limiting part 220 abut against each other, and the socket 320 is pressed towards the lock box 100, there may be other limiting protrusions 210 abutting against the positioning protrusions 321 along the circumference of the rotation axis 200, which can further improve the stability when unlocking.

[0070] Please see Figures 7-8 And return to refer to Figure 3 In another embodiment of this application, the outer side wall of the rotating shaft 200 is provided with a limiting protrusion 240, and the inner side wall of the sleeve portion 320 is provided with a protrusion 323. The protrusion 323 is located on the side of the limiting protrusion 240 facing the lock box 100, and along the radial direction of the rotating shaft 200, the limiting protrusion 240 is located between the inner side wall of the sleeve portion 320 and the first side wall 323a of the protrusion 323, wherein the first side wall 323a of the protrusion 323 faces the rotating shaft 200.

[0071] That is, the protrusion 323 is closer to the lock box 100 than the limiting protrusion 240. In this way, after the socket 320 is pulled to a certain position, the limiting protrusion 240 can be abutted by the protrusion 323, which can prevent the socket 320 from sliding too much and breaking the electrical connection wire.

[0072] The protrusion 323 can be integrally formed with the sleeve 320, or it can be installed by snap-fit, screw connection or other methods, which are not limited here.

[0073] Furthermore, when the sleeve portion 320 moves along the axial direction of the rotation axis 200 until the protrusion 323 contacts the limiting protrusion 240, the first limiting portion 322 is at least partially located between the second limiting portion 220 and the third limiting portion 230 on both sides along the axial direction of the rotation axis 200.

[0074] Thus, when the sliding sleeve portion 320 is in motion, the first limiting portion 322, the second limiting portion 220, and the third limiting portion 230 are prevented from being spaced apart in the axial direction. This ensures that when the sleeve portion 320 rotates relative to the rotation axis 200, the second limiting portion 220 and the third limiting portion 230 are located within the movement trajectory of the first limiting portion 322, so that the first limiting portion 322 can abut against the second limiting portion 220 or the third limiting portion 230, thereby achieving rapid and accurate positioning of the handle assembly 300.

[0075] In one embodiment of this application, the outer surface of the limiting protrusion 240 is curved. Compared with a flat surface or a sharp edge, the curved surface has a smoother contact surface. When the limiting protrusion 240 contacts the inner wall of the sleeve portion 320, the curved surface can more effectively disperse the contact pressure, reduce friction and wear, thereby extending the service life of the limiting protrusion 240.

[0076] In one embodiment of this application, the limiting protrusion 240 is made of an elastic material, such as rubber or silicone, which is not limited here. In this way, when the limiting protrusion 240 contacts the inner wall of the sleeve portion 320, there is less friction, making it difficult to cause wear to the sleeve portion 320. Even if friction and collision occur, the noise is small or almost non-existent. When the sleeve portion 320 moves along the axial direction of the rotation axis 200 until the protrusion 323 contacts the limiting protrusion 240, the noise generated is also relatively small. Since the limiting protrusion 240 is elastic, it can also play a certain buffering role, thereby reducing the wear on the protrusion 323.

[0077] Secondly, when the limiting protrusion 240 is made of an elastic material, the limiting protrusion 240 can deform. Thus, during the process of the sleeve portion 320 being fitted onto the rotating shaft 200, when the limiting protrusion 240 comes into contact with the protrusion 323, it can be compressed, thereby preventing interference with the protrusion 323.

[0078] In another embodiment of this application, the limiting protrusion 240 may include a glass bead and a spring, and the side wall of the rotating shaft 200 is provided with a clearance hole. The spring is disposed in the clearance hole, and the glass bead extends to the outer side wall of the rotating shaft 200. Thus, during the process of the sleeve portion 320 being sleeved on the rotating shaft 200, when the limiting protrusion 240 contacts the protrusion 323, the glass bead is subjected to a squeezing force and will retract into the clearance hole, and will not interfere with the protrusion 323. After the handle assembly 300 is installed in place, the spring resets, which also drives the glass bead to reset, thus playing a limiting role. The whole process does not require manual adjustment, greatly improving the installation efficiency.

[0079] Please see Figure 6 At least three limiting protrusions 210 include a third limiting protrusion 213, which is located between the second limiting part 220 and the third limiting part 230. The first limiting part 322 is located outside the rotation trajectory of the third limiting protrusion 213. Two adjacent positioning grooves 321a include a first positioning groove 321a1. When the third limiting protrusion 213 is inserted into the first positioning groove 321a1, the handle body 310 and the length direction of the lock box 100 have a second included angle, which is B. B satisfies that 0°≤B≤10°. At this time, it corresponds to the "vertical installation" of the handle assembly 300. B can be any two sets of values ​​between 0°, 5°, 10° or above.

[0080] It is important to understand that after the door is assembled in the factory, the handle body 310 and the lock box 100 can be parallel or nearly parallel in length, that is, the handle assembly 300 is in a "vertical" state. This is suitable for situations where there is no solid wall on the side of the door frame or the side of the door frame is far from a solid wall. However, when there is a solid wall on the side of the door frame, the user can adjust the handle assembly 300 to the first or second position depending on whether the door opens to the right or left. This will not be explained further here.

[0081] In this embodiment of the application, since the user needs to lock manually, the lock in this embodiment of the application is a mechanical lock body. However, in some mechanical lock bodies, since wires are needed to connect the lock cylinder and the access control system to realize the remote control function, the wires are routed in the handle assembly 300. The lock body can be opened or closed remotely through the access control system, which improves the convenience and security of use.

[0082] In this embodiment, since the installation position of the handle assembly 300 needs to be changed, to avoid breaking the electrical connection wire, please refer to [the relevant documentation / reference needed]. Figure 9 The handle body 310 forms an electrical cavity 310a, and corresponding electrical components, such as circuit boards, are installed inside the electrical cavity 310a.

[0083] The socket 320 has a mounting groove 320a, and the rotating shaft 200 extends into the mounting groove 320a. The bottom of the mounting groove 320a has a wire passage 320b, which connects the electrical cavity 310a and the mounting groove 320a. Through the wire passage 320b, the electrical components in the lock box 100 can be electrically connected to the electrical components in the electrical cavity 310a.

[0084] Please see Figure 9The wire passage 320b extends circumferentially along the rotating shaft 200, and the rotating shaft 200 has a wire passage hole 200a along its axial direction. When the sleeve part 320 rotates relative to the rotating shaft 200, the wire passage 320b communicates with the wire passage hole 200a.

[0085] In this embodiment, when the handle assembly 300 is adjusted, the rotating shaft 200 remains stationary. Therefore, only the cable passage 320b200a extends circumferentially along the rotating shaft 200, forming an arc shape. In this way, when the handle assembly 300 is adjusted, the electrical connection cable always passes through the cable passage 320b, preventing the edge of the cable passage 320b from pulling the connection cable when the handle assembly 300 rotates, thus affecting the service life of the electrical connection cable.

[0086] Please see Figure 8 In one embodiment of this application, a portion of the rotating shaft 200 extends to the back side of the lock box 100. A mounting hole 200b extends through the rotating shaft 200 along its axial direction. The lock also includes a connector 400, which is disposed in the mounting hole 200b and connects the handle assembly 300 and the rotating shaft 200.

[0087] The back side of the lock box 100 refers to the side of the lock box 100 that is away from the handle assembly 300. In this way, by connecting the handle assembly 300 and the rotating shaft 200 together from the back side of the lock box 100, the overall appearance of the lock can be made neater and more beautiful. Furthermore, connecting the rotating shaft 200 and the handle assembly 300 along the axial direction can make the connection between the two tighter and relatively stable.

[0088] On the other hand, the connector 400 can be either a screw or a bolt. In this embodiment, a bolt, specifically a hexagonal bolt, is used as an example. By using a hexagonal bolt, it can be inserted into the mounting hole 200b, preventing it from protruding and causing injury. Please refer to [link to relevant documentation]. Figure 8 In this embodiment, the socket 320 is also provided with a connection hole for cooperating with a hexagonal bolt to increase the stability of the connection.
