Description

Technical Field

[0001] This application relates to the field of smart lock technology, and in particular to a lock control device. Background Technology

[0002] Smart locks are widely used due to their convenience and security. However, when choosing a smart lock, some users do not want to replace their existing doors or the non-smart traditional locks on them. Therefore, a lock control device can be installed on the traditional lock, and the lock control device can drive the knob of the traditional lock to turn, thereby realizing the intelligent transformation of the traditional lock.

[0003] Due to differences in usage habits and technical standards, the knobs of traditional door locks in different countries and regions vary greatly in shape and size. In order for the lock control device to be compatible with knobs of different shapes and sizes, various special accessories usually need to be designed, which will increase the manufacturing cost of the lock control device. Utility Model Content

[0004] One of the technical problems addressed by this application is how to reduce the manufacturing cost of the locking device.

[0005] A locking control device includes a main unit, a driver, and a clamping mechanism. The driver is rotatably connected to the main unit, and the clamping mechanism is connected to the driver. The clamping mechanism includes:

[0008] An adjustment unit is movably connected to the mounting base and is used to drive the plurality of clamping parts to slide relative to the mounting base, so that the plurality of clamping parts move toward or away from each other.

[0009] In one embodiment, the mounting base has two parallel sliding grooves, and the clamping unit further includes a sliding part connected to the clamping part. There are two clamping units, and the sliding parts of the two clamping units slide and engage with different sliding grooves respectively. The clamping part is located outside the sliding groove.

[0010] In one embodiment, the clamping unit further includes a fixing member, which is fixedly connected to the sliding portion, and the mounting seat abuts between the clamping portion and the fixing member.

[0012] In one embodiment, the adjusting unit includes a gear rotatably connected to the mounting base, and the clamping unit further includes a rack connected to the clamping part. The gear simultaneously meshes with racks on two of the clamping units, and when the gear rotates, the sliding directions of the two racks are opposite.

[0013] In one embodiment, at least one of the following schemes is also included:

[0014] Both the gear and the rack are made of metal.

[0015] The mounting base forms a receiving cavity, the clamping part is located outside the receiving cavity, and the rack and the gear are located inside the receiving cavity.

[0016] In one embodiment, the adjustment unit further includes an adjustment member disposed on the mounting base, the adjustment member being used to drive the rack movement of one of the clamping units, or the adjustment member being used to drive the gear to rotate.

[0017] In one embodiment, the adjusting member includes an adjusting bolt, which is rotatably disposed on the mounting base and threadedly connected to one of the clamping units, the axial direction of the adjusting bolt being parallel to the movement direction of the clamping portion.

[0018] In one embodiment, the mounting base is provided with a first limiting part, and the adjusting bolt is provided with a second limiting part. The first limiting part and the second limiting part cooperate to restrict the axial movement of the adjusting bolt on the mounting base.

[0019] In one embodiment, the first limiting portion includes a limiting protrusion, and the second limiting portion includes a limiting groove, the limiting groove being disposed around the central axis of the adjusting bolt on the outer surface of the adjusting bolt; or...

[0020] The first limiting part includes a limiting groove, and the second limiting part includes a limiting protrusion. The limiting protrusion is disposed on the outer surface of the adjusting bolt around the central axis of the adjusting bolt.

[0021] In one embodiment, the clamping unit further includes an abutment member, the flexibility of which is greater than that of the clamping portion, and the clamping portion has a recess extending to the free end of the clamping portion, the abutment member being embedded in the recess.

[0023] In one embodiment, the mounting base has a positioning hole and a fixing hole, the driver cooperates with the positioning hole, and the driver is inserted into the fixing hole and detachably connected to the mounting base.

[0024] One technical advantage of one embodiment of this application is that, since the adjusting unit drives multiple clamping parts to move towards or away from each other, the spacing between the multiple clamping parts is adjustable, allowing the clamping parts to clamp knobs of different shapes and sizes. This improves the versatility and applicability of the clamping mechanism and the entire locking device, thus eliminating the need for numerous accessories and reducing the manufacturing cost of the locking device. It also improves the ease of use of the locking device, thereby enhancing the user experience. Attached Figure Description

Detailed Implementation

[0037] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0038] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0039] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0041] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0042] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0043] See Figure 1 , Figure 2 and Figure 3 This application provides a lock control device 10 for installation on the knob of a traditional door lock. The knob of a traditional door lock is installed on the indoor side of the door, allowing the user to lock and unlock the door by rotating the knob. The lock control device 10 provided in this application is installed on the knob of a traditional door lock and can be driven to rotate the knob electrically or manually, thereby achieving automatic or manual locking and unlocking of the traditional door lock.

[0044] The lock control device 10 includes a main unit 11, a driver 12, and a clamping mechanism 13. The driver 12 is rotatably connected to the main unit 11, and the clamping mechanism is drive-connected to the driver 12. The clamping mechanism 13 is used to clamp the knob of the traditional door lock. When the driver 12 rotates relative to the main unit 11, the clamping mechanism 13 and the knob it clamps will rotate synchronously with the driver 12. That is, the driver 12 will drive the knob of the traditional door lock to rotate through the clamping mechanism 13, thereby realizing the locking and unlocking of the traditional door lock.

[0045] In an optional embodiment, the main unit 11 includes a main unit housing and an electric drive device. A driver 12 is rotatably connected to the main unit housing, and the electric drive device is located inside the main unit housing and is drive-connected to the driver 12. The driver 12 can rotate relative to the main unit 11 under the drive of the electric drive device within the main unit 11, or it can rotate relative to the main unit 11 under manual operation. Optionally, a clutch device is provided between the electric drive device and the driver 12, which prevents interference between manual rotation and electric rotation of the driver 12. The electric drive device can be a motor.

[0046] Since the knob is located indoors, and the clamping mechanism 13 is used to clamp the knob of a traditional door lock, the main unit 11, the driver 12, and the clamping mechanism 13 are all installed on the indoor side of the door. The main unit 11 also includes a communication unit and a control unit. The communication unit receives lock / unlock signals, and the control unit controls the electric drive unit inside the main unit housing based on the lock / unlock signals to drive the driver 12 and the clamping mechanism 13 to rotate, thus achieving electric locking and unlocking. In an optional embodiment, the lock control device 10 may also include a control panel installed outdoors. The control panel can receive lock / unlock commands via password, fingerprint, Bluetooth, or NFC (Near Field Communication), and upon receiving the lock / unlock command, sends a lock / unlock signal to the indoor main unit 11. After receiving the lock / unlock signal, the communication unit inside the main unit 11 causes the electric drive unit inside the main unit 11 to operate, driving the clamping mechanism 13 and the knob to rotate. Alternatively, the lock / unlock signal can be sent directly to the indoor main unit 11 via remote control, causing the electric drive unit inside the main unit 11 to drive the clamping mechanism 13 and the knob to rotate. It is understandable that when the drive actuator 12 is manually turned inside the room, the traditional door lock can also be deadbolted.

[0047] See Figure 1 and Figure 4 In some embodiments, the clamping mechanism 13 includes a mounting base 100, clamping units 200, and an adjusting unit 300. The mounting base 100 is fixedly connected to the driver 12, so the driver 12 can drive the mounting base 100 and the entire clamping mechanism 13 to rotate synchronously. The host 11 can also drive the mounting base 100 and the entire clamping mechanism 13 to rotate synchronously via the driver 12. There are multiple clamping units 200, each of which is slidably connected to the mounting base 100. Each clamping unit 200 includes a clamping part 210. The multiple clamping units 200 cooperate with each other to clamp the knob of a traditional door lock. The adjusting unit 300 is movably connected to the mounting base 100. The adjusting unit 300 is used to drive the multiple clamping parts 210 to slide relative to the mounting base 100, so that the multiple clamping parts 210 move towards or away from each other, thereby changing the distance between the multiple clamping parts 210, so that the multiple clamping parts 210 can clamp knobs of different shapes and sizes.

[0048] If a mode is adopted where the distance between the two clamping parts 210 cannot be adjusted, the locking device 10 would need to be equipped with various different accessories to accommodate knobs of different sizes. This would increase the manufacturing cost of the locking device 10 and force users to purchase a large number of unnecessary accessories, thereby reducing the user experience of the locking device 10. However, for the clamping mechanism 13 in the above embodiment, since the distance between the multiple clamping parts 210 is adjustable, the clamping parts 210 can clamp knobs of different shapes and sizes, thereby improving the versatility of the clamping mechanism 13 and the entire locking device 10. This can save the need for a large number of accessories, thereby reducing the manufacturing cost of the locking device 10 and improving the ease of use of the locking device 10, thus improving the user experience.

[0049] See Figure 2 , Figure 3 and Figure 4 In some embodiments, the mounting base 100 may include a bottom shell 110, a side cylinder 120, and a top cover 130. The side cylinder 120 is arranged around the bottom shell 110, and the side cylinder 120 and the bottom shell 110 form a receiving cavity 140. The top cover 130 is detachably connected to the side cylinder 120, for example, by bolting or snap-fitting. The top cover 130 is used to cover the receiving cavity 140. The top cover 130 of the mounting base 100 may have positioning holes 131 and fixing holes 132. There may be multiple positioning holes 131 and fixing holes 132. The driver 12 includes a positioning element 12a, which cooperates with the positioning hole 131 to position the clamping mechanism 13 and prevent the clamping mechanism 13 from rotating or sliding relative to the driver 12. The driver 12 may also include a plug 12b, which is inserted into the fixing hole 132 and detachably connected to the mounting base 100. For example, the plug 12b can be snapped into the mounting base 100, thus realizing a fixed connection between the clamping mechanism 13 and the driver 12.

[0050] In some embodiments, the number of clamping units 200 can be two, and the clamping portions 210 of the two clamping units 200 are spaced apart along the sliding direction of the clamping units 200. An adjusting unit 300 is movably connected to the mounting base 100, and the adjusting unit 300 is used to drive the two clamping portions 210 to move towards or away from each other, thereby changing the distance between the two clamping portions 210 so that the two clamping portions 210 can clamp knobs of different shapes and sizes. In other embodiments, the number of clamping units 200 can be three or more. For example, when the number of clamping units 200 is three, the three clamping units 200 can move towards or away from each other in a direction perpendicular to the axis around which the clamping mechanism 13 rotates. In other words, the three clamping units 200 can move towards or away from each other along three different radii within the same circumference, the plane of which is perpendicular to the axis around which the clamping mechanism 13 rotates.

[0051] See Figure 4 and Figure 6 In some embodiments, the mounting base 100 is provided with two sliding grooves 111, which can be formed on the bottom shell 110. The two sliding grooves 111 extend in a straight line and are arranged in parallel. Each clamping unit 200 also includes a sliding part 220. The clamping part 210 and the sliding part 220 are connected to each other. The sliding parts 220 of the two clamping units 200 slide and engage with different sliding grooves 111 respectively. The clamping part 210 is located outside the sliding groove 111 and the receiving cavity 140. In other embodiments, the sliding groove 111 can also be formed on the sliding part 220.

[0052] See Figure 4 , Figure 5 and Figure 6 In some embodiments, the clamping unit 200 further includes a fixing member 230, which is fixedly connected to the sliding part 220, for example, by bolts or snap-fit ​​connections. The mounting base 100 abuts against the clamping part 210 and the fixing member 230. Specifically, the fixing member 230 can abut against the bottom shell 110 of the mounting base 100, so that the bottom shell 110 is abutted between the fixing member 230 and the clamping part 210. This can be understood as the fixing member 230 and the clamping part 210 clamping the bottom shell 110, thus effectively preventing the sliding part 220 and the entire clamping unit 200 from falling off the mounting base 100.

[0053] See Figure 4 , Figure 5 , Figure 6 and Figure 7For example, the slide groove 111 includes a first groove 1111 and a second groove 1112. The middle area of ​​the bottom wall of the first groove 1111 is recessed to form the second groove 1112. The second groove 1112 communicates with the receiving cavity 140. The edge area of ​​the bottom wall of the first groove 1111 does not have a groove, so the edge area forms a stepped surface 1113. The stepped surface 1113 surrounds the second groove 1112. The sliding part 220 includes a sliding body 221 and a lug 222. The clamping part 210 can be connected to the sliding body 221 and / or the lug 222. There can be two lugs 222. The two lugs 222 protrude from two opposite sides of the sliding body 221. The lugs 222 slide with the first groove 1111 and abut against the stepped surface 1113. The sliding body 221 slides with the second groove 1112. The fixing member 230 is located within the accommodating cavity 140 and connected to the sliding part 220, with the fixing member 230 located at the end of the second groove 1112 away from the first groove 1111. Since the fixing member 230 abuts against the inner side of the bottom shell 110 of the mounting base 100, and the lug 222 abuts against the stepped surface 1113, the mounting base 100 is clamped between the lug 222 and the fixing member 230. This causes interference between the fixing member 230 and the lug 222 and the mounting base 100, effectively preventing the sliding body 221 from falling out of the second groove 1112, ultimately achieving a sliding fit between the entire clamping unit 200 and the sliding groove 111.

[0054] See Figure 8 , Figure 9 and Figure 10 In some embodiments, the adjusting unit 300 includes a gear 310 rotatably connected to the base shell 110. Each clamping unit 200 may also include a rack 2211, which may be disposed on the sliding body 221 of the sliding portion 220. The racks 2211 on the two clamping units 200 are respectively disposed on both sides of the gear 310, and the gear 310 meshes with the racks 2211 on both clamping units 200 simultaneously. When the gear 310 rotates, the two racks 2211 move in opposite directions, so the sliding directions of the two sliding portions 220 are opposite, which also makes the sliding directions of the two clamping portions 210 opposite, thereby realizing the opposite or opposite movement of the two clamping portions 210 to change the distance between the two clamping portions 210.

[0055] In some embodiments, both gear 310 and rack 2211 are located within the receiving cavity 140, which allows the mounting base 100 to protect gear 310 and rack 2211, preventing external interference with their operation. Gear 310 and rack 2211 can be made of metal, which improves their structural strength and prevents deformation and failure of the gear teeth.

[0056] See Figure 8 , Figure 9 and Figure 10 In some embodiments, the adjusting unit 300 further includes an adjusting member 320, which is disposed on the mounting base 100 and drives one of the clamping units 200 to move. When one of the clamping units 200 slides, it drives the gear 310 to rotate via the rack 2211. The rotating gear 310 then drives the other clamping unit 200 to slide in the opposite direction via the rack 2211. In short, one of the clamping units 200 acts as a power source, and this power source drives the other clamping unit 200 to slide via the gear 310. In one embodiment, the adjusting member 320 is used to drive the rack 2211 of one of the clamping units 200 to move. The movement of one rack 2211 simultaneously drives the gear 310 to rotate, thereby synchronously driving the rack 2211 of the other clamping unit 200 to move, ultimately achieving the opposite or opposite movement of the two clamping units 200.

[0057] In other embodiments, the adjusting member 320 can directly drive the gear 310 to rotate. In this case, the gear 310 is the power source, and the rotating gear 310 will simultaneously drive the two clamping units 200 to move in opposite directions.

[0058] See Figure 8 , Figure 10 and Figure 11 In some embodiments, the adjusting member 320 may include an adjusting bolt 321, which is rotatably mounted on the side cylinder 120 of the mounting base 100. The axial direction of the adjusting bolt 321 is parallel to the movement direction of the clamping part 210, and the adjusting bolt 321 is threadedly connected to one of the clamping units 200. The adjusting bolt 321 may be threadedly connected to the sliding part 220, or threadedly connected to the sliding part 220. The axial direction of the adjusting bolt 321 is parallel to the extension direction of the slide groove 111. The mounting base 100 can limit the axial direction of the adjusting bolt 321. During the rotation of the adjusting bolt 321 on the mounting base 100 around its central axis, the adjusting bolt 321 cannot slide relative to the mounting base 100 along its own axial direction. This makes the adjusting bolt 321 function similarly to a lead screw, so when the adjusting bolt 321 rotates, the rotation of the adjusting bolt 321 is converted into the sliding of the clamping unit 200.

[0059] It is understandable that, given the self-locking capability of the thread, once the adjusting bolt 321 drives the clamping unit 200 to the designated position, the clamping unit 200 cannot slide off from the designated position. This improves the stability and reliability of the two clamping parts 210 clamping the knob. In other embodiments, the adjusting member 320 can be a cylinder or a cam, as long as it can drive one of the clamping units 200 to slide.

[0060] See Figure 8 , Figure 10 and Figure 11 The mounting base 100 is provided with a first limiting part, and the adjusting bolt 321 is provided with a second limiting part. The first limiting part and the second limiting part cooperate to restrict the axial movement of the adjusting bolt 321 on the mounting base 100, thereby ensuring that the rotational movement of the adjusting bolt 321 can be smoothly converted into the linear movement of the clamping part 210.

[0061] In one embodiment, the first limiting part includes a limiting protrusion 150, and the second limiting part includes a limiting groove 330. The limiting groove 330 is disposed around the central axis of the adjusting bolt 321 on the outer surface of the adjusting bolt 321. The limiting protrusion 150 can be inserted into the annular limiting groove 330, thereby limiting the axial movement of the adjusting bolt 321 and ensuring that the adjusting bolt 321 can rotate normally.

[0062] In another embodiment, the first limiting part includes a limiting groove 330, and the second limiting part includes a limiting protrusion 150. The limiting protrusion 150 is disposed around the central axis of the adjusting bolt 321 on the outer surface of the adjusting bolt 321, and is inserted into the limiting groove 330. It can be understood that the limiting protrusion 150 and the two inner sidewalls of the limiting groove 330, which are spaced apart along the axial direction of the adjusting bolt 321, abut against each other, thereby achieving axial limiting of the adjusting bolt 321.

[0063] See Figure 8 , Figure 10 and Figure 11In some embodiments, the side cylinder 120 of the mounting base 100 has a first hole 121 and a second hole 122. The first hole 121 and the second hole 122 are coaxially arranged. The diameter of the second hole 122 is smaller than that of the first hole 121. The second hole 122 is closer to the receiving cavity 140 than the first hole 121, so that the second hole 122 is directly connected to the receiving cavity 140. This makes the first hole 121 and the second hole 122 form a stepped hole. The adjusting bolt 321 includes an adjusting rod 3211 and an adjusting cap 3212. The cross-section of the adjusting cap 3212 is larger than that of the adjusting rod 3211. The adjusting cap 3212 is rotatably engaged with the first hole 121, and the adjusting cap 3212 abuts against the bottom wall surface of the first hole 121 along the axial direction of the adjusting bolt 321, so that the adjusting cap 3212 cannot enter the second hole 122. This can effectively prevent the entire adjusting bolt 321 from sliding relative to the mounting base 100 along its own axial direction. The adjusting rod 3211 is rotatably engaged with the second hole 122, and the adjusting rod 3211 passes through the receiving cavity 140 and is threadedly connected to the fixing member 230 of the clamping unit 200. Therefore, by driving the adjusting cap 3212 to rotate counterclockwise or clockwise through the jig, the entire adjusting bolt 321 will rotate counterclockwise or clockwise, thus driving the clamping unit 200 to slide back and forth.

[0064] See Figure 8 , Figure 10 and Figure 11In some embodiments, the adjusting rod 3211 includes a first rod 3211a and a second rod 3211b, which are coaxially arranged. The first rod 3211a connects the second rod 3211b and the adjusting cap 3212. The cross-section of the first rod 3211a is smaller than that of the second rod 3211b, making the adjusting rod 3211 resemble a stepped shaft. Therefore, the end of the second rod 3211b has a limiting surface 3211c, which surrounds the first rod 3211a. It can be understood that the adjusting cap 3212... The gap between 212 and the limiting surface 3211c forms the limiting groove 330. The mounting base 100 may also include the limiting protrusion 150. The limiting protrusion 150 is located in the accommodating cavity 140 and is provided on the bottom shell 110 and / or the top cover 130. For example, both the bottom shell 110 and the top cover 130 are provided with the limiting protrusion 150. The limiting surface 3211c and the adjusting cap 3212 abut against the limiting protrusion 150 along the axial direction of the adjusting rod 3211. Obviously, the limiting surface 3211c and the adjusting cap 3212 are spaced apart along the axial direction of the adjusting bolt 321. Therefore, based on the fact that the adjusting cap 3212 abuts against the bottom wall of the first hole 121 along the axial direction of the adjusting bolt 321, the limiting surface 3211c abuts against the limiting protrusion 150 along the axial direction of the adjusting bolt 321. This further enhances the limiting function of the mounting base 100 on the adjusting bolt 321 and further prevents the adjusting bolt 321 from sliding relative to the mounting base 100 along its own axial direction. This improves the stability and reliability of the driving of the adjusting component 320 on the clamping assembly, ensuring that the clamping part 210 can effectively clamp the knob.

[0065] See Figure 7 and Figure 8 In some embodiments, the clamping unit 200 further includes an abutment 240, which is fixedly connected to the clamping part 210. The abutment 240 is used to abut against the knob to clamp the knob. For example, the abutment 240 can be made of plastic material, so that the flexibility of the abutment 240 is greater than that of the clamping part 210. This can increase the friction between the abutment 240 and the knob, prevent the abutment 240 from detaching from the knob, and thus improve the stability and reliability of the connection between the clamping mechanism 13 and the knob.

[0066] Of course, the surface of the abutment 240 that abuts against the knob can be provided with uneven anti-slip stripes, thereby further increasing the friction between the abutment 240 and the knob. A groove can be provided on the clamping part 210, and the abutment 240 directly mates with the groove, so that the abutment 240 is embedded in the clamping part 210, thus improving the connection strength between the abutment 240 and the clamping part 210. Of course, the surface of the abutment 240 used for clamping can be flush with the surface of the clamping part 210.

[0067] See Figure 7 and Figure 8 In some embodiments, the clamping unit 200 further includes a fastener 250, which may be a screw or the like. The fastener 250 passes through the clamping portion 210 and is threadedly connected to the abutment member 240. The abutment member 240 has at least two fastening holes 241 arranged along a spacing direction perpendicular to the two clamping portions 210. The fastener 250 passes through the clamping portion 210 and engages with the fastening holes 241. When the fastener 250 engages with different fastening holes 241, the length of the abutment member 240 protruding from the free end of the clamping portion 210 changes. Therefore, by changing the protrusion length of the abutment member 240 relative to the free end of the clamping portion 210, the clamping unit 200 can accommodate different protrusion lengths of the knob relative to the thickness of the door body, ensuring that the abutment member 240 and the clamping portion 210 can clamp knobs of different sizes. In other embodiments, an elongated hole such as a waist-shaped hole may be provided on the abutment member 240. When the fixed position of the fastener 250 in the elongated hole changes, the protrusion length of the abutment member 240 relative to the free end of the clamping part 210 can also be changed.

[0068] In other embodiments, multiple fastening holes 241 may also be provided on the clamping part 210. When the fastener 250 is engaged with different fastening holes 241, the length of the abutment 240 protruding from the free end of the clamping part 210 can also be changed.

[0069] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
