Description

Technical Field

[0001] This utility model relates to the field of door lock technology, specifically to a sliding door lock and a sliding door structure. Background Technology

[0002] Door locks are widely used, often found on entrance doors and other similar locations. After the entrance door is turned, the door lock locks the door, and then the door can be opened using a key or other means.

[0003] Front doors typically feature a rotating mechanism, while doors in certain environments often have a sliding mechanism, such as those between a balcony and living room, a kitchen and living room, or doors mounted on protective covers. Sliding door structures generally cannot use the locks found on front doors, leading to slow unlocking and a less user-friendly experience. Furthermore, locking a sliding door often requires additional locking operations besides moving it, further slowing down the locking process.

[0004] Therefore, how to solve the shortcomings of the existing technology, such as the sliding door's unlocking process affecting the user experience and the slow locking process, has become the research topic to be solved by this utility model. Utility Model Content

[0005] The purpose of this utility model is to provide a sliding door lock and a sliding door structure.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A sliding door lock includes a hook assembly, a lock assembly, and a handle assembly. The hook assembly is used to connect to a door frame and to lock the lock assembly. The lock assembly is used to connect to a door panel and is movable relative to the hook assembly along a first direction. The handle assembly is used to connect to the door panel, and a portion of the handle assembly is movable vertically to release the lock assembly from locking the lock assembly. The first direction is parallel to the horizontal direction.

[0008] This application is mainly used for locking a door structure that moves laterally, and is particularly applicable to the following door structure: the door structure includes a door frame, a door panel, and a door casing. The door frame and door casing are installed on a wall or other location and distributed along a first direction. The door panel can move relative to the door frame along the first direction. The door casing has a storage groove for storing at least a portion of the door panel. The storage groove is provided through at least one end of the door casing along the first direction. When the door structure is in a blocked state, the door panel fits against the door frame.

[0009] In the above solution, during installation, the hook assembly is installed on the door frame, and the door lock assembly and door handle assembly are installed on the door panel. The specific installation method and the corresponding settings of the door structure (such as the door panel having an internal slot structure and the door frame having a slot for accommodating the hook assembly) are conventional settings and can refer to existing settings, without any restrictions here; as the door panel approaches the door frame, the door lock assembly and door handle assembly simultaneously approach the hook assembly. After the door lock assembly contacts the hook assembly, the hook assembly locks the door lock assembly, making it impossible for the door panel to separate from the door frame, thus achieving stable closure of the door structure.

[0010] With the above settings, the door panel can be moved to contact the door frame, and the locking hook assembly can be locked to the door lock assembly in a gradual manner without any additional operation. The door panel can be locked quickly while moving laterally. The door handle assembly can be used as a handle to facilitate moving the door panel, or it can be used to release the locking hook assembly from the door lock assembly.

[0011] In a further technical solution, the lock hook assembly includes a mounting component and a locking component connected to each other. The mounting component is used to connect with the door frame, and the locking component is used to lock the door lock assembly.

[0012] The door lock assembly includes a mounting part, a fastener, and a locking part. The fastener and the locking part are both rotatably mounted on the mounting part, and the mounting part is used to connect with the door panel.

[0013] The fastener is provided with a first slot, a second slot, and a third slot arranged sequentially along a first direction. The engaging component includes a latch. The locking component can push the fastener and the latch located in the third slot to move so that the latch engages in the second slot and the first slot engages with the locking component, thereby realizing the locking of the door lock component by the lock hook assembly. The locking process occurs with the movement of the door panel and does not require additional operation. The purpose of locking the door is achieved by closing the door to the correct position. It is ergonomic and the engaging structure involved is simple and efficient, especially suitable for door panels that move horizontally (such as lateral or vertical movement).

[0014] In a further technical solution, the door lock assembly further includes a first elastic element and a second elastic element. The first elastic element is connected to the mounting part and the engaging part, and the second elastic element is connected to the mounting part and the fastener. The first elastic element and the second elastic element are respectively used to reset the engaging part and the fastener, thereby promoting the orderly arrangement of the structure within the door lock assembly.

[0015] In a further technical solution, the first elastic element and the second elastic element each include two first hook structures and two second hook structures. The mounting part is provided with two first slots, the engaging part is provided with a second slot, and the fastener is provided with a third slot. This arrangement facilitates the installation and disassembly of the first elastic element.

[0016] A further technical solution, in order to allow users to operate the door structure from both sides, is that the door handle assembly includes an inner door handle mechanism and an outer door handle mechanism that are structurally identical and symmetrically distributed along the second direction. Both the inner door handle mechanism and the outer door handle mechanism are used to connect to the door panel and are used to release the locking hook assembly from the door lock assembly; the first direction and the second direction are orthogonal.

[0017] A further technical solution is that the inner door handle mechanism includes a first housing, a first push button, and a first connecting member. The first housing is used to connect with the door panel. The first push button is vertically movably installed in the first housing. The first push button can push the locking member to rotate through the first connecting member to release the locking hook assembly from the door lock assembly. Only pressing the first push button is needed to release the locking hook assembly from the door lock assembly. The required structure is simple, and the operation is simple and efficient.

[0018] The outer door handle mechanism includes a second housing, a second push button, and a second connector. The second housing is used to connect with the door panel. The second push button is vertically movably mounted on the second housing. The second push button can push the locking member to rotate through the second connector to release the locking hook assembly from the door lock assembly.

[0019] In a further technical solution, the inner door handle mechanism includes a first elastic part installed on the first housing, and the outer door handle mechanism includes a second elastic part installed on the second housing. The first elastic part and the second elastic part are respectively used to reset the first push button and the second push button.

[0020] A further technical solution also includes a door linkage assembly, wherein the first connector and the second connector are connected through the door linkage assembly.

[0021] A further technical solution is that the door linkage assembly includes a linkage with a connecting groove. The end of the first connector and the end of the second connector are close to or fitted within the connecting groove, so that the first connector and the second connector can move synchronously and stably. The longer the structural length of the second connector extends into the inside of the first connector, the smaller the area required for the door handle assembly.

[0022] A further technical solution also includes a door lock unit and a lock hook unit for locking the door lock unit. The lock hook unit is used to connect with the door frame, and the door lock unit is used to connect with the door panel. The door lock unit is located on the side of the door lock assembly away from the lock hook assembly. The lock hook unit and the lock hook assembly have the same structure and are symmetrically arranged along the first direction. The door lock unit and the door lock assembly have a centrally symmetrical structure.

[0023] The door linkage assembly also includes a support member and an unlocking member connected to the linkage. The linkage is rotatably connected to the support member. The unlocking member is used to release the locking hook unit from the door lock unit. The user can simultaneously release the locking hook unit from the door lock unit and the locking hook assembly from the door lock assembly through the inner door handle mechanism or the outer door handle mechanism.

[0024] A sliding door structure is also provided herein, which includes a door frame, a door panel, and a door sleeve, and further includes a sliding door lock as described in any of the above embodiments.

[0025] The terms "first," "second," etc., used in this article do not specifically refer to order or sequence, nor are they intended to limit this case; they are merely used to distinguish components or operations described using the same technical terms.

[0026] The terms "connection" or "positioning" as used in this article can refer to two or more components or devices making direct physical contact with each other, or making indirect physical contact with each other, or to two or more components or devices operating or moving with each other.

[0027] The terms “include,” “including,” and “have” used in this article are all open-ended, meaning they include but are not limited to.

[0028] Unless otherwise specified, the terms used herein generally have their ordinary meaning in the context of the art, the subject matter, and the specific context. Certain terms used to describe this case will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the case.

[0029] The terms “front,” “back,” “up,” “down,” “left,” and “right” used in this article are directional terms. In this case, they are only used to describe the positional relationship between the structures and are not intended to limit the specific direction of the protection scheme or its actual implementation.

[0030] The working principle and advantages of this utility model are as follows: During installation, the lock hook assembly is installed on the door frame, and the door lock assembly and door handle assembly are installed on the door panel. During the locking process, the door lock assembly and door handle assembly move towards the lock hook assembly, and the locking member pushes the fastener to move and enter the first slot. The latch in the third slot moves to the second slot, so that the first slot engages with the locking member and the latch engages with the second slot in the locked state. With the above settings, the operation of locking the door lock assembly with the lock hook assembly can be gradually achieved as the door panel is moved to contact the door frame. No additional operation is required, and the horizontally moving door panel can be locked quickly. The door handle assembly can serve as a handle to facilitate the movement of the door panel, and can also quickly release the lock hook assembly from the door lock assembly. During the unlocking process, only a part of the door handle assembly needs to be moved vertically. Attached Figure Description

[0050] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0051] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0052] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0053] See Figures 1-14A sliding door lock includes a hook assembly 1, a lock assembly 2, and a handle assembly 3. The hook assembly 1 is used to connect to a door frame 7 and to lock the lock assembly 2. The lock assembly 2 is used to connect to a door panel 8 and can move relative to the hook assembly 1 in a first direction. The handle assembly 3 is used to connect to the door panel 8, and a portion of the handle assembly 3 can move vertically to release the lock assembly 1 from locking the lock assembly 2. The first direction is parallel to the horizontal direction.

[0054] It should be noted that there are multiple reference points in the first direction, such as... Figure 1 In the width direction of the middle door panel 8, for example... Figure 9 The length direction of the connecting rod 41; the second direction is perpendicular to the first direction and the vertical direction, specifically as follows: Figure 9 The distribution direction of the inner door handle mechanism 31 and the outer door handle mechanism 32.

[0055] This application is mainly used for locking a laterally moving door structure, also known as a sliding door structure, and is particularly suitable for the following sliding door structure: The sliding door structure includes a door frame 7, a door panel 8, and a door sleeve 9. The door frame 7 and the door sleeve 9 are installed on a wall or other location and distributed along a first direction. The door panel 8 can move relative to the door frame 7 along the first direction. The door sleeve 9 has a storage groove for storing at least a portion of the door panel 8. The storage groove is provided to pass through at least one end of the door sleeve 9 along the first direction. When the door structure is in a blocked state, the door panel 8 fits against the door frame 7, such as... Figure 1 As shown.

[0056] During installation, the hook assembly 1 is installed on the door frame 7, and the door lock assembly 2 and door handle assembly 3 are installed on the door panel 8. The specific installation method and the corresponding settings of the door structure (such as the door panel 8 having an internal slot structure and the door frame 7 having a slot for accommodating the hook assembly 1) are conventional settings and can be referred to the existing settings. No restrictions are imposed here. As the door panel 8 approaches the door frame 7, the door lock assembly 2 and door handle assembly 3 simultaneously approach the hook assembly 1. After the door lock assembly 2 contacts the hook assembly 1, the hook assembly 1 locks the door lock assembly 2, so that the door panel 8 cannot be separated from the door frame 7, thus achieving stable closure of the door structure.

[0057] With the above settings, the door panel 8 can be moved to contact the door frame 7, and the operation of locking the door lock component 2 by the hook component 1 can be gradually realized without additional operation. The horizontally moving door panel 8 can be locked quickly. The door handle component 3 can be used as a handle to facilitate the movement of the door panel 8, and can also quickly release the lock hook component from the door lock component. During the unlocking process, only the vertical part of the door handle component needs to be moved.

[0058] See Figures 2-5In this embodiment, the lock hook assembly 1 includes a mounting member 11 and a locking member 12 connected to each other. The mounting member 11 is used to connect with the door frame 7, and the locking member 12 is used to lock the door lock assembly 2.

[0059] The door lock assembly 2 includes a mounting part 21, a fastener 22, and a locking part 23. The fastener 22 and the locking part 23 are both rotatably mounted on the mounting part 21. The mounting part 21 is used to connect with the door panel 8.

[0060] The fastener 22 is provided with a first slot 221, a second slot 222, and a third slot 223 arranged sequentially along a first direction. The engaging member 23 includes a latch 231. The locking member 12 can push the fastener 22 and the latch 231 located in the third slot 223 to move so that the latch 231 engages in the second slot 222 and the first slot 221 engages with the locking member 12, thereby realizing the locking of the door lock assembly 2 by the lock hook assembly 1.

[0061] When the door lock assembly 2 contacts the lock hook assembly 1, the locking member 12 contacts the fastener 22, and the latch 231 is in the third slot 223. As the door panel 8 continues to move, the locking member 12 pushes the fastener 22 to rotate around the predetermined rotation path. The fastener 22 contacts the engaging member 23, so the fastener 22 pushes the engaging member 23 to rotate around the predetermined rotation path. Finally, the latch 231 separates from the third slot 223 and enters the second slot 222, while the end of the locking member 12 enters the first slot 221. At this time, if the door panel 8 is pulled back, the latch 231 is stuck in the second slot 222, making the pull-back operation impossible. The door panel 8 and the door frame 7 are in a stable fitting stage.

[0062] Further explanation of the above process is as follows: The locking member 12 can be cylindrical without specific restrictions, and the same applies to the mounting member 11; initially, the locking tongue 231 is in the third slot 223 (restricting the initial position of the locking tongue 231); when locked, the locking tongue 231 is in the second slot 222. The locking tongue 231 is the engaging end of the engaging member 23. The locking tongue 231 and the second slot 222 are key structures, and they can be considered to be in an meshing relationship, thereby achieving the locking of the door panel 8; taking the engaging member 23 as an example, the engaging member 23 can be rotatably mounted on the mounting part 21 through a rotating shaft structure. The mounting part 21 is a conventional setting without restrictions; continuing to take the engaging member 23 as an example, under normal circumstances, the rotation path of the engaging member 23 is in the plane of the first direction, that is, the first engaging member 23 can be regarded as rotating clockwise or counterclockwise in the plane of the first direction.

[0063] The locking process described above occurs as the door panel 8 moves, requiring no additional operation. The door is locked once it is closed, which is ergonomic. The locking structure involved is simple and efficient, and is especially suitable for door panels 8 that move horizontally (such as laterally or vertically).

[0064] See Figure 2 In this embodiment, the door lock assembly 2 further includes a first elastic element 24 and a second elastic element 25. The first elastic element 24 is connected to the mounting part 21 and the engaging part 23, and the second elastic element 25 is connected to the mounting part 21 and the fastener 22. The first elastic element 24 and the second elastic element 25 are respectively used to reset the engaging part 23 and the fastener 22.

[0065] The first elastic member 24 is connected to the mounting part 21 and the engaging member 23. Specifically, the first elastic member 24 is connected to the structure of the engaging member 23 other than the locking tongue 231. If the locking tongue 231 is the engaging end of the engaging member 23, then the first elastic member 24 can be connected to the end of the engaging member 23 away from the engaging end.

[0066] The first elastic element 24 is used to reset the locking element 23, and the second elastic element 25 is used to reset the fastener 22. Optionally, both the first elastic element 24 and the second elastic element 25 are tension springs.

[0067] Taking the locking member 23 as an example, the locking tongue 231 in the locking member 23 moves between the third locking groove 223 and the second locking groove 222. When the door panel 8 is unlocked, the first elastic member 24 can cause the locking tongue 231 to re-enter the third locking groove 223.

[0068] It should be added that the structure within the door lock component 2 needs to be arranged in an orderly manner. A disordered structure is prone to negative effects, such as affecting the reusability of the door lock component 2. Resetting the structure within the door lock component 2 can help achieve an orderly arrangement of the structure within the door lock component 2.

[0069] See Figure 3 In this embodiment, the first elastic member 24 and the second elastic member 25 respectively include two first hook structures 241 and two second hook structures 251. The mounting part 21 is provided with two first slots 211, the engaging member 23 is provided with a second slot 232, and the fastener 22 is provided with a third slot 224.

[0070] Taking the first elastic element 24 as an example, when installing the first elastic element 24, one of the first hook structures 241 hooks one of the first slots 211, and the other first hook structure 241 hooks the second slot 232. With this setting, it is convenient to install and remove the first elastic element 24.

[0071] For ease of understanding, the first elastic element 24 is set as a tension spring, and the first hook structure 241 is the hook ring on the tension spring.

[0072] See Figure 8 In this embodiment, the door handle assembly 3 includes an inner door handle mechanism 31 and an outer door handle mechanism 32 with the same structure and symmetrically distributed along the second direction. Both the inner door handle mechanism 31 and the outer door handle mechanism 32 are used to connect to the door panel 8 and are used to release the lock hook assembly 1 from locking the door lock assembly 2. The first direction, the second direction and the vertical direction are orthogonal to each other.

[0073] The first direction is the direction of movement of the door panel 8, and the second direction is the thickness direction of the door panel 8.

[0074] Taking the inner door handle mechanism 31 as an example, when the user is inside the house, the user can pull the inner door handle mechanism 31 in the first direction to move the door panel 8. The user can also use the inner door handle mechanism 31 to release the lock hook assembly 1 from locking the door lock assembly 2.

[0075] The inner door handle mechanism 31 and the outer door handle mechanism 32 allow the user to operate the door structure from both sides, for example, from inside and outside the house.

[0076] See Figures 4-6 , Figure 8 In this embodiment, the inner door handle mechanism 31 includes a first housing 311, a first push button, and a first connecting member 312. The first housing 311 is used to connect with the door panel 8. The first push button is vertically movably installed on the first housing 311. The first push button can push the locking member 23 to rotate through the first connecting member 312 to release the locking hook assembly 1 from the door lock assembly 2.

[0077] The outer door handle mechanism 32 includes a second housing 321, a second push button 322, and a second connector 323. The second housing 321 is used to connect with the door panel 8. The second push button 322 is vertically movably installed on the second housing 321. The second push button 322 can push the locking member 23 to rotate through the second connector 323 to release the locking hook assembly 1 from the door lock assembly 2.

[0078] Taking the inner door handle mechanism 31 as an example, the first housing 311 is installed inside the door panel 8. The first housing 311 may be provided with a handle structure. The user can press the first push button, which moves down and causes the engaging member 23 to move through the first connecting member 312. Optionally, the first connecting member 312 is a rivet. The first push button is riveted to the first connecting member 312. The first connecting member 312 moves down and causes the engaging member 23 to rotate and separate from the second slot 222, thereby releasing the lock hook assembly 1 from the door lock assembly 2.

[0079] With the above settings, simply pressing the first push button will release the lock hook assembly 1 from the door lock assembly 2. The required structure is simple, and the operation is simple and efficient.

[0080] See Figure 7 In this embodiment, the inner door handle mechanism 31 includes a first elastic part installed on the first housing 311, and the outer door handle mechanism 32 includes a second elastic part 324 installed on the second housing 321. The first elastic part and the second elastic part 324 are respectively used to reset the first push button and the second push button 322.

[0081] Optionally, the first elastic part and the second elastic part 324 are configured as a spring structure. For a detailed description of the first elastic part and the second elastic part 324, please refer to the above description of the first elastic member 24 and the second elastic member 25.

[0082] See Figure 8 In this embodiment, a door linkage assembly 4 is also included, and the first connector 312 and the second connector 323 are connected through the door linkage assembly 4.

[0083] The door linkage assembly 4 can be placed inside the door panel 8. Taking the connection of the first connector 312 and the second connector 323 through the door linkage assembly 4 as an example, the connection method is supplemented. The specific connection method is not specified here, but the connection is a conventional and basic setting that can be adjusted according to the actual situation. There are detachable connections in the form of threaded connection, snap-fit, etc., as well as fixed connections in the form of welding, etc.

[0084] See Figure 8 In this embodiment, the door linkage assembly 4 includes a linkage 41, on which a connecting groove 411 is provided. The end of the first connector 312 and the end of the second connector 323 are close to or fitted within the connecting groove 411.

[0085] The first connector 312 and the second connector 323 are connected by the door linkage assembly 4, specifically, by the connecting groove 411.

[0086] Both the end of the first connector 312 and the end of the second connector 323 are inserted into the communicating groove 411. Optionally, the end of the first connector 312 is provided with a square opening, and the end of the second connector 323 is in the shape of a cone or the like. The end of the second connector 323 is inserted into the inner side of the end of the first connector 312 through the opening in the communicating groove 411.

[0087] With the above settings, the first connector 312 and the second connector 323 can move synchronously and stably. The longer the second connector 323 extends into the inside of the first connector 312, the smaller the area required for the door handle assembly 3.

[0088] See Figure 1 , Figure 9 In this embodiment, it also includes a door lock unit 5 and a lock hook unit 6 for locking the door lock unit 5. The lock hook unit 6 is used to connect with the door frame 9, and the door lock unit 5 is used to connect with the door panel 8. The door lock unit 5 is located on the side of the door lock assembly 2 away from the lock hook assembly 1. The lock hook unit 6 and the lock hook assembly 1 have the same structure and are symmetrically arranged along the first direction. The door lock unit 5 and the door lock assembly 2 have a centrally symmetrical structure.

[0089] The door linkage assembly 4 also includes a support member 42 and an unlocking member 43 connected to the linkage 41. The linkage 41 is rotatably connected to the support member 42, and the unlocking member 43 is used to release the lock hook unit 6 from locking the door lock unit 5.

[0090] As mentioned above, the storage groove is provided through at least one end of the door frame 9 along the first direction. When it passes through the end of the door frame 9 away from the wall, the locking hook unit 6 can only be connected to the door frame 9. When it passes through both ends of the door frame 9, the locking hook unit 6 can be connected to both the door frame 9 and the wall.

[0091] When the door panel 8 is pulled open and locked, the lock hook assembly 1, door lock assembly 2, door lock unit 5, and lock hook unit 6 are arranged sequentially along the first direction. When the door panel 8 is inserted into the door frame 9, pushing the door panel 8 into place will automatically lock the door panel 8 into the door frame 9.

[0092] Optionally, along the first direction, the door lock assembly 2 and the door lock unit 5 are respectively installed at both ends of the door panel 8.

[0093] The ends of the first connector 312 and the second connector 323 are fitted together in the communicating groove 411. Thus, any movement of the first connector 312 or the second connector 323 can cause the connecting rod 41 to rotate. Taking the first connector 312 as an example, the first connector 312 moves down and causes the engaging member 23 to rotate and separate from the second slot 222. At this time, the first connector 312 causes the unlocking member 43 to move up through the connecting rod 41. Since the door lock unit 5 and the door lock assembly 2 are centrally symmetrical, the unlocking member 43 can cause the engaging member 23 in the door lock unit 5 to rotate and separate from the second slot 222. With this setting, it can be regarded as unlocking two door locks at the same time.

[0094] With the above settings, the user can simultaneously release the locking of the door lock unit 5 by the inner door handle mechanism 31 and the locking of the door lock assembly 2 by the lock hook assembly 1 through the inner door handle mechanism 31 or the outer door handle mechanism 32.

[0095] Optionally, the support extends vertically, and the connecting rod 41 is rotatably connected to the support 42 via a pivot.

[0096] See Figure 1 , Figures 10-14 Furthermore, a sliding door structure is also provided, which includes a door frame 7, a door panel 8, and a door sleeve 9. The sliding door structure also includes the sliding door lock of any of the above embodiments.

[0097] like Figure 1 The sliding door structure is in its initial state, with the door frame 7 and door panel 8 locked together.

[0098] like Figure 10 When the sliding door structure is in the unlocked state on the closed side, pull down the push button (referring to the first push button or the second push button 322, the same below) to make the locking part 23 rotate clockwise, and the lock tongue 231 rotates into the third slot 223. Under the action of the first elastic member 24 and the second elastic member 25, the door lock assembly 2 separates from the lock hook assembly 1, completing the unlocking. At the same time, the unlocking part 43 (which can be set as a rivet) pushes the right locking part 23 upward to rotate counterclockwise.

[0099] like Figure 11 When the sliding door structure is in the unlocked state on the closed side, the push button and door lock assembly 2 are reset. When the push button is released, the push button moves upward to complete the reset. Under the action of the first elastic member 24 and the second elastic member 25, the lock tongue 231 re-engages with the third slot 223.

[0100] like Figure 12 When the sliding door structure is in the locked state on the opening side, push the door to the right and the lock hook unit 6 locks the door lock unit 5. The specific process is the same as the locking of the door lock assembly 2 by the lock hook assembly 1.

[0101] like Figure 13When the sliding door structure is in the unlocked state on the open side, the unlocking component 43 pushes the right-side locking component 23 upward to rotate counterclockwise.

[0102] like Figure 14 When the sliding door structure is in the unlocked state on the open side, refer to the instructions for the unlocked state on the closed side of the sliding door structure.

[0103] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
