AI Technical Summary

Technical Problem

In some door body designs, one side of the door frame is adjacent to the solid wall, resulting in a very limited gap between the door frame and the wall, which in turn limits the lateral range of motion of the handle and increases the risk of collision between the handle and the wall.

Method used

A lock is designed, including a lock box, a rotary shaft and a handle assembly. A limit bump and a limit groove are provided on the outer periphery of the rotating shaft, and a position bump and a position groove are provided on the socket of the handle assembly. By sliding the socket with respect to the rotation axis, the positioning bump and the limit bump can be inserted into the corresponding groove, thereby adjusting the installation position of the handle assembly, increasing its movement space, and reducing the probability of hitting the wall.

Benefits of technology

By adjusting the installation position of the handle assembly, it increases its movement space, effectively reducing the risk of the handle and the wall collision. At the same time, the overall structural strength of the lock is enhanced by the coordination of the positioning bumps and the limit bumps.

[0041] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0042] In the related art, there are some door bodies where one side of the door frame is a solid wall, and the gap in the door frame is small, leaving little space for the lateral movement of the handle, so the space for the handle to move is limited, and there is a risk of hitting the wall.

[0043] If the length direction of the lock box is along the height direction of the door body, and the handle is initially extended along the height direction of the door body, and one side of the door frame is a solid wall, then when the handle is turned, the path range of the free end of the handle is wider, and it is easy to collide with the wall.

[0044] In order to solve the above technical problems, the present 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, that is, the installation position of the handle assembly 300 relative to the lock box 100 can be adjusted, so that the space for the handle assembly 300 to move can be adjusted to reduce the probability of hitting the wall.

[0045] See below for more information. Figure 1-2 , further explaining the lock in the embodiment of the present application.

[0046] The lock box 100 has key components such as springs and lock cores inside. The lock box 100 provides a closed space to protect the key components such as springs and lock cores inside the lock from erosion by the external environment, such as dust, moisture, corrosion, etc., to ensure the normal operation of the lock and extend its service life. Of course, for fingerprint locks and password locks, electrical components such as circuit boards and batteries can also be set inside the lock box 100. In order to protect the internal components and ensure the strength of the material, the material of the lock box 100 can be selected as hard materials such as aluminum alloy and stainless steel. Of course, the lock box 100 can also use other materials with greater structural strength, such as plastics.

[0047] The lock box 100 is usually designed with an installation hole 200b or a fixing device to facilitate the installation of the lock on a 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 body to meet the user's door opening habits.

[0048] See also Figure 3-4 The rotating shaft 200 is rotatably installed on the lock box 100. At least two limiting protrusions 210 are arranged on the outer circumference of the rotating shaft 200. The at least two 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 connection portion 320 connected to the handle body 310. The sleeve connection portion 320 is sleeved on the rotating shaft 200. At least two positioning protrusions 321 are arranged on the inner side wall of the sleeve connection portion 320. At least two positioning protrusions 321 are arranged at intervals along the circumference of the sleeve connection portion 320. A positioning groove 321a is formed between two adjacent positioning protrusions 321.

[0049] Among them, the positioning protrusion 321 and the limiting protrusion 210 play a role of pre-positioning. 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 movement space of the handle assembly 300 can be adjusted to reduce the probability of hitting the wall.

[0050] 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 portion 320 and the rotating shaft 200 are kept relatively fixed through the connecting piece 400, such as by using screws or bolts to make the handle assembly 300 in a locked state. When the position of the handle assembly 300 needs to be replaced, the screws or bolts are removed to make the handle assembly 300 in an unlocked state, and the sleeve portion 320 can slide along the axial direction of the rotating shaft 200 relative to the rotating shaft 200, so that the positioning protrusion 321 can be disengaged from the limiting groove 210a, making it easier for the positioning protrusion 321 to be inserted into another limiting groove 210a to achieve the position change of the handle assembly 300.

[0051] In addition, in the embodiment of the present application, when the positioning protrusion 321 is inserted into the limiting groove 210a, along the circumference of the rotating shaft 200, at least one positioning protrusion 321 abuts against the limiting protrusion 210, that is, the positioning protrusion 321 and the limiting protrusion 210 can form a bite, forming a stable mechanical connection. This connection helps to prevent the rotating shaft 200 from unnecessary displacement or shaking when subjected to force, thereby enhancing the overall structural strength of the lock.

[0052] Among them, there can be two, three, four, five, etc. of the limiting protrusions 210. When there are two or three limiting protrusions 210, generally, there are also two or three positioning protrusions 321, that is, one positioning protrusion 321 can be abutted against the limiting protrusion 210, or two positioning protrusions 321 can be abutted against the limiting protrusion 210, depending on the actual situation.

[0053] See also Figure 5-6 In one embodiment of the present application, a first limiting portion 322 is disposed at one end of the sleeve portion 320 adjacent to the handle body 310, and a second limiting portion 220 and a third limiting portion 230 are disposed at one end of the rotating shaft 200 away from the lock box 100. The second limiting portion 220 and the third limiting portion 230 are located on the rotation track of the rotating shaft 200 and are respectively located on both sides of the first limiting portion 322;

[0054] Please continue to read Figure 7-8 , when the sleeve portion 320 rotates relative to the rotating shaft 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;

[0055] When the sleeve portion 320 rotates relative to the rotation axis 200 along the second direction N until the first limiting portion 322 abuts against the third limiting portion 230 , the third limiting portion 230 prevents the sleeve portion 320 from rotating along the second direction N. The first direction M is opposite to the second direction N.

[0056] That is, when the handle assembly 300 is in the unlocked state, after the sleeve portion 320 rotates to a certain angle along the first direction M, the first limiting portion 322 will abut against the second limiting portion 220, so that the sleeve portion 320 can be positioned, and then along the axial direction of the rotating shaft 200, the positioning protrusion 321 can also accurately enter the limiting groove 210a.

[0057] Similarly, after the sleeve connection part 320 rotates to a certain angle along the second direction N, the first limiting part 322 will abut against the third limiting part 230, so that the sleeve connection part 320 can be positioned, and then along the axial direction of the rotating shaft 200, the positioning protrusion 321 can also accurately enter the limiting groove 210a.

[0058] That is, the positioning protrusion 321 and the limiting groove 210a can be accurately matched without the user having to align the positions of the positioning protrusion 321 and the limiting groove 210a, thereby greatly improving the efficiency of position switching of the handle assembly 300.

[0059] Furthermore, on the basis of the previous embodiment, a guide groove 200c is opened on the rotating shaft 200, and the guide groove 200c extends along the circumference of the rotating shaft 200. The second limiting portion 220 and the third limiting portion 230 are formed at both ends of the guide groove 200c. Since the guide groove 200c extends along the circumference of the rotating shaft 200, when the handle assembly 300 switches its position, the first limiting portion 322 can move along the guide groove 200c, thereby ensuring the stability of the handle assembly 300 when rotating.

[0060] When the sleeve portion 320 rotates to the two ends of the guide groove 200c (i.e., the second limit portion 220 and the third limit portion 230), the user can feel obvious resistance or sound feedback, so that the user can clearly know that the handle has been rotated to the extreme position. When the handle assembly 300 is switched, positioning can be achieved quickly and accurately to ensure product consistency.

[0061] Since the guide groove 200c extends along the circumference of the rotating shaft 200, when the handle assembly 300 switches its position, the first limiting portion 322 can move along the guide groove 200c, thereby ensuring the stability of the handle assembly 300 when rotating.

[0062] The guide groove 200c can be directly formed on the rotating shaft 200 through simple processes such as machining or casting. The guide groove 200c is directly opened on the rotating shaft 200 to form a limiting portion. No additional processing steps are required, and the need for additional limiting components is reduced, which simplifies the structure of the lock and reduces production costs.

[0063] For further information, see Figure 6 Along the axial direction of the rotating shaft 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 abuts against the limiting protrusion 210 to limit the rotation of the handle assembly 300 relative to the rotating shaft 200. When the handle assembly 300 is in the second preset position, the positioning protrusion 321 is spaced apart from the limiting protrusion 210 along the axial direction of the rotating shaft 200.

[0064] 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 be abutted against the limiting protrusion 210 to limit the rotation of the sleeve part 320. When the handle assembly 300 is in the second preset position, the positioning protrusion 321 is separated from the limiting protrusion 210, and the sleeve part 320 can rotate relative to the rotating shaft 200, thereby facilitating the position switching of the handle assembly 300 and reducing the probability of the handle assembly 300 hitting the wall.

[0065] When the handle assembly 300 is in the first preset position and the second preset position, part of the first limiting portion 322 is located between the two side walls of the second limiting portion 220 and the third limiting portion 230 along the axial direction of the rotating shaft 200, and part of the first limiting portion 322 is located between the two side walls of the second limiting portion 220 and the third limiting portion 230 along the axial direction of the rotating shaft 200, that is, after the sleeve portion 320 rotates a certain angle, the first limiting portion 322 can still abut against the second limiting portion 220 or the third limiting portion 230, thereby ensuring that the handle assembly 300 is quickly and accurately positioned when switching positions.

[0066] When the second limiting portion 220 and the third limiting portion 230 are formed at both ends of the guide groove 200c, the design of the guide groove 200c enables the sleeve portion 320 to maintain a stable trajectory during rotation, reducing the risk of lock failure due to shaking or deflection. Regardless of whether the handle assembly 300 is in the first preset position or the second preset position, a portion of the first limiting portion 322 will extend into the guide groove 200c, which helps to further stabilize the position of the handle assembly 300 and prevent it from accidental movement. The guide groove 200c also provides additional guidance and support, that is, it can ensure that after the sleeve portion 320 rotates to a certain extent, the first limiting portion 322 can abut against the second limiting portion 220 or the third limiting portion 230, ensuring the stability and accuracy of the handle assembly 300 during rotation.

[0067] See also Figure 6 In one embodiment of the present application, a limiting protrusion 240 is provided on the outer side wall of the rotating shaft 200, and a protrusion 323 is provided on the inner side wall of the sleeve portion 320. The protrusion 323 is provided 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.

[0068] That is, the protrusion 323 is closer to the lock box 100 than the limiting protrusion 240. Thus, after the sleeve 320 is pulled to a certain position, the limiting protrusion 240 can abut against the protrusion 323, which can prevent the sleeve 320 from sliding too much and thus tearing the electrical connection line.

[0069] The protruding portion 323 may be integrally formed with the sleeve portion 320 , or installed by means of a snap connection, a screw connection, etc., which is not limited here.

[0070] Furthermore, when the sleeve portion 320 moves along the axial direction of the rotating shaft 200 until the protruding portion 323 contacts the limiting protrusion 240 , the positioning protrusion 321 and the limiting protrusion 210 are spaced apart from each other along the axial direction of the rotating shaft 200 .

[0071] That is, the axial movement stroke of the sleeve part 320 relative to the rotating shaft 200 is precisely controlled, which can not only reduce the possibility of directly pulling out the sleeve part 320 and causing the sleeve part 320 to fall off, but also avoid breaking the electrical connection line. Since the positioning protrusion 321 and the limiting protrusion 210 are distributed at intervals along the axial direction of the rotating shaft 200, that is, the positioning protrusion 321 does not abut against the limiting protrusion 210, that is, it does not affect the rotation of the sleeve part 320 relative to the rotating shaft 200, so that the position of the handle assembly 300 can be easily adjusted.

[0072] In addition, when the sleeve portion 320 moves along the axial direction of the rotating shaft 200 until the protrusion 323 contacts the limiting protrusion 240, a portion of the first limiting portion 322 is located between the two side walls of the second limiting portion 220 and the third limiting portion 230 along the axial direction of the rotating shaft 200, that is, when the sleeve portion 320 rotates relative to the rotating shaft 200, the first limiting portion 322 can abut against the second limiting portion 220 or the third limiting portion 230, thereby ensuring that the handle assembly 300 is quickly and accurately positioned when switching positions.

[0073] In one embodiment of the present application, the outer surface of the limiting protrusion 240 is a curved surface. Compared with a flat surface or a sharp edge, the curved surface design 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, and thus extend the service life of the limiting protrusion 240.

[0074] In one embodiment of the present application, the limiting protrusion 240 is made of an elastic material, specifically, rubber material, silicone material, etc., which is not limited here. In this way, when the limiting protrusion 240 contacts the inner wall of the sleeve portion 320, the friction is smaller, and it is difficult to cause wear to the sleeve portion 320. Even if friction and collision occur, the noise is small, or there is no noise. When the sleeve portion 320 moves along the axial direction of the rotating shaft 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.

[0075] Secondly, when the limiting protrusion 240 is made of elastic material, the limiting protrusion 240 can be deformed. In this way, when the sleeve portion 320 is sleeved on the rotating shaft 200, the limiting protrusion 240 can be compressed when it contacts the protruding portion 323, so as not to interfere with the protruding portion 323.

[0076] In another embodiment of the present 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 an avoidance hole, the spring is arranged in the avoidance hole, and the glass bead extends to the outer wall of the rotating shaft 200. In this way, when the sleeve portion 320 is sleeved on the rotating shaft 200, when the limiting protrusion 240 contacts the protrusion 323, the glass bead is squeezed and will retract into the avoidance hole without interfering with the protrusion 323. After the handle assembly 300 is installed in place, the spring is reset, driving the glass bead to reset as well, thereby playing a limiting role. The entire process does not require manual adjustment, thereby greatly improving the installation efficiency.

[0077] See also Figure 8 In one embodiment of the present application, at least three limiting protrusions 210 are arranged on the outer circumference of the rotating shaft 200, at least three positioning protrusions 321 are arranged on the inner side wall of the sleeve portion 320, one of the two adjacent positioning grooves 321a is a first positioning groove 321a1, and the other is a second positioning groove 321a2, and the at least three limiting protrusions 210 include a first limiting protrusion 211, and when the first limiting protrusion 211 is inserted into the second positioning groove 321a2, the handle body 310 and the lock body 310 are locked. The box 100 is arranged at an angle in the length direction, and the first limiting portion 322 abuts against the second limiting portion 220 and one of the third limiting portions 230. When the first limiting protrusion 211 is inserted into the first positioning groove 321a1, the handle body 310 and the lock box 100 have a second angle, and the second angle is B. B satisfies 0°≤B≤20°. At this time, it corresponds to the "vertical installation" of the handle assembly 300, and B can be 0°, 10°, 20° or a range between any two of the above groups of values.

[0078] Among them, when the handle body 310 is parallel to the length direction of the lock box 100, the handle assembly 300 is "vertically installed". It should be understood that after the door body is assembled in the factory, the handle body 310 is parallel to the length direction of the lock box 100, that is, the handle assembly 300 is in a "vertically installed" state, which can be suitable for some situations where there is no solid wall on the door frame side, or the door frame side is far away from the solid wall. In the case where there is a solid wall on the door frame side, the user can adjust the handle assembly 300 according to the situation of the door body opening to the right or left. The handle body 310 and the lock box 100 are arranged at an angle in the length direction. The length direction of the lock box 100 may refer to the height direction of the door body or the length direction of the door body. 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 may be 30°, 50°, 70°, 90°, 120° or a range between any two groups of values ​​above. Within this range, the handle assembly 300 has sufficient space for movement, and the handle assembly 300 is difficult to contact the wall.

[0079] From the user's perspective outside the door, when the door is opened to the left, the lock box 100 is located on the left side of the door. At this time, the handle body 310 can be adjusted to be set at an angle with the length direction of the lock box 100, that is, the free end of the handle is located on the lower right side of the lock box 100 toward the door body. In this way, the handle assembly 300 has sufficient space for movement and is unlikely to collide with the wall on the left.

[0080] When the first limiting protrusion 211 is inserted into the second positioning groove 321a2, the first limiting portion 322 abuts against the second limiting portion 220 and one of the third limiting portion 230. That is, the user can rotate the sleeve portion 320 so that the first limiting portion 322 abuts against the second limiting portion 220 or the third limiting portion 230, and then press the sleeve portion 320 to insert the first limiting protrusion 211 into the second positioning groove 321a2. The user does not need to align the positions of the first limiting protrusion 211 and the second positioning groove 321a2, thereby greatly improving the efficiency of the position switching of the handle assembly 300.

[0081] Based on the previous embodiment, please refer to Figure 8 There are three positioning grooves 321a, which are arranged in sequence. The middle positioning groove 321a is the first positioning groove 321a1, and the positioning grooves 321a on both sides are the second positioning grooves 321a2. When the first limiting protrusion 211 is respectively inserted into the two second positioning grooves 321a2, the free ends of the handle body 310 are respectively arranged on the first side and the second side of the lock box 100, and the first side and the second side are respectively located on the opposite sides of the lock box 100.

[0082] When the first limiting portion 322 abuts against the second limiting portion 220 , the adjustment handle assembly 300 can be defined as being in the first position. When the second limiting portion 220 abuts against the third limiting portion 230 , the adjustment handle assembly 300 can be defined as being in the second position.

[0083] Exemplarily, the first direction M can be counterclockwise, and the first side is the left side of the lock box 100, and the second direction N can be clockwise, and the second side is the right side of the lock box 100. In this way, the lock box 100 in the embodiment of the present application can adapt to the situation where the door opens to the left or the right, and has a wider range of applicability.

[0084] From the user's perspective outside the door, when the door is opened 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 space for movement and is unlikely to collide with the wall on the left.

[0085] 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 space for movement and is unlikely to collide with the wall on the right.

[0086] In the embodiment of the present application, since the user is required to lock the door manually, the lock in the embodiment of the present application is aimed at a mechanical lock body. However, in some mechanical lock bodies, since wires are required to connect the lock core and the access control system to achieve a remote control function, the wiring is routed inside the handle assembly 300, and the lock body can be remotely opened or closed through the access control system, thereby improving the convenience and safety of use.

[0087] In the embodiment of the present application, since the installation position of the handle assembly 300 needs to be switched, in order to avoid the electrical connection line from being torn off, in the embodiment of the present application, please refer to Fig. 9 The handle body 310 forms an electrical cavity 310a, and corresponding electrical components, such as a circuit board, are installed in the electrical cavity 310a.

[0088] The sleeve portion 320 is formed with a mounting groove 320a, and the rotating shaft 200 extends into the mounting groove 320a. A wire passing opening 320b is provided at the bottom of the mounting groove 320a, and the wire passing opening 320b is connected to the electrical cavity 310a and the mounting groove 320a. Through the wire passing opening 320b, the electrical components in the lock box 100 can be electrically connected to the electrical components in the electrical cavity 310a.

[0089] See also Fig. 9 The wire passing opening 320b extends along the circumferential direction of the rotating shaft 200. The rotating shaft 200 is provided with a wire passing hole 200a along its axial direction. When the sleeve portion 320 rotates relative to the rotating shaft 200, the wire passing opening 320b is connected with the wire passing hole 200a.

[0090] In the embodiment of the present application, when the handle assembly 300 is adjusted, the rotating shaft 200 does not move, so only the wire opening 320b extends along the circumference of the rotating shaft 200, that is, the whole is in an arc shape. In this way, when the handle assembly 300 is adjusted, the electrical connection line always passes through the wire opening 320b, which avoids the edge of the wire opening 320b pulling the connection line when the handle assembly 300 is rotated, thereby affecting the service life of the electrical connection line.

[0091] See also Figure 6 In one embodiment of the present application, part of the rotating shaft 200 extends to the back side of the lock box 100, and a mounting hole 200b is provided in the rotating shaft 200 along the axial direction of the rotating shaft 200. The lock also includes a connecting member 400, which is disposed in the mounting hole 200b and connects the handle assembly 300 and the rotating shaft 200.

[0092] Among them, the back side of the lock box 100 refers to the side of the lock box 100 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 appearance of the entire lock can be made neater and more beautiful, and 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.

[0093] On the other hand, the connecting member 400 can be a screw or a bolt. In the embodiment of the present application, a bolt is used, and a hexagonal bolt is used for exemplary description. By using a hexagonal bolt, the hexagonal bolt can be inserted into the mounting hole 200b to avoid protrusion and injury. Please refer to Figure 6 In the embodiment of the present application, a connection hole that cooperates with the hexagonal bolt is also opened on the sleeve portion 320 to increase the stability of the connection.
