Description

Technical Field

[0001] This utility model relates to the technical field of posture correction devices, specifically to a support mechanism and a posture correction study table including the support mechanism. Background Technology

[0002] In daily life and study scenarios, desktops are usually kept horizontal. However, this setting can easily cause users to have poor posture, such as leaning forward and hunching. Maintaining poor posture for a long time can damage the user's eyesight and cervical spine, and increase the probability of myopia, hunchback and spinal curvature.

[0003] To address the aforementioned issues, posture-correcting desk devices placed on desktops have emerged on the market. For example, patent CN222737482U discloses a posture-correcting study desk. This desk includes a main panel with a learning surface and at least one set of support legs. The support legs are rotatably connected to the main panel and have a folded-down position that forms an angle with the learning surface. The angle of inclination of the learning surface relative to a horizontal reference plane can be adjusted using the support legs. This patent, to some extent, makes it easier for users to maintain a comfortable and healthy sitting posture for extended periods, thereby reducing damage to eyesight and the cervical spine, and lowering the risk of myopia, hunchback, and spinal curvature.

[0004] When a user leans over the tabletop to write or read, the tabletop bears significant pressure. Adjusting posture or moving the body can cause the tabletop to shift, leading to sudden rotation and collapse of the support legs, instability, and even accidents. While this patented design incorporates positioning blocks and locking mechanisms to mitigate this issue, the positioning blocks and locking mechanisms rely on the positioning block squeezing through the ridge of the locking mechanism. This requires significant external force to overcome friction and achieve gear adjustment or support leg switching. Furthermore, the positioning blocks and locking mechanisms are located near the pivot, resulting in a short lever arm. However, when the user operates the end of the support leg, the lever arm is large, and the body pressure often exceeds normal operating force, making it difficult to control the force. Excessive force may overload and break the pivot or other components, while insufficient force provides almost no gear control, and the tabletop will still collapse when adjusting posture or moving the body. In addition, the positioning blocks and locking mechanisms are mostly injection-molded plastic, which is prone to wear and tear over time, ultimately rendering them ineffective and resulting in poor overall stability. Utility Model Content

[0005] The purpose of this invention is to provide a support mechanism whose support legs do not easily rotate during use, exhibiting good stability and strong practicality.

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

[0007] A support mechanism includes a support foot, a limiting component, an unlocking component, and a positioning plate. The limiting component includes an elastic element, with both ends of the elastic element abutting against the positioning plate and the limiting component, respectively. The unlocking component is disposed on the limiting component, and the limiting component is in close contact with the support foot.

[0008] The support leg is also equipped with a hinge shaft, which is used to rotate around the support leg during the opening or closing process, and the position of the positioning plate relative to the hinge shaft remains fixed.

[0009] After the support leg is opened, the limiting component moves under the action of the elastic element and locks the support leg in place; when the unlocking component is moved, the limiting component moves in the opposite direction to release the locked state.

[0010] Furthermore, the limiting component also includes a movable plate, a limiting block, and a connecting strip; the unlocking component is set on the movable plate, and the two ends of the connecting strip are fixedly connected to the movable plate and the limiting block respectively; the limiting block is close to the support foot and locks and limits the support foot after it is opened.

[0011] Furthermore, a slot is provided on the side where the support foot mates with the limiting block, and a snap-fit ​​part matching the slot is provided on the connecting strip. After the support foot is opened, the snap-fit ​​part is inserted into the slot for limiting.

[0012] Furthermore, an assembly slot is provided on the movable plate, and both the elastic element and the positioning plate are set in the assembly slot. One end of the elastic element abuts against the positioning plate, and the other end abuts against the inner wall of the assembly slot. A limit post is also provided in the assembly slot, and the end of the elastic element that abuts against the inner wall of the assembly slot is sleeved on the limit post.

[0013] Furthermore, the limiting block mates with the side wall of the support foot or with the limiting groove provided at the hinge edge of the support foot;

[0014] When the limiting block engages with the side wall of the support foot, the limiting block abuts against the side wall of the support foot after the support foot is closed; after the support foot is opened, the limiting block disengages from the side wall of the support foot and locks the support foot in place.

[0015] When the limiting block engages with the limiting groove near the hinge edge of the support foot, the end of the connecting strip extends into the limiting groove; when the support foot is closed, the limiting block is located in the limiting groove and abuts against the side wall of the limiting groove; when the support foot is opened, the limiting block disengages from the side wall of the limiting groove and locks the support foot in place.

[0016] Furthermore, there are two or more support feet, each of which is coaxially set through a hinge shaft and distributed in an embedded manner from the inside to the outside. The number of limiting components corresponds to the number of support feet. The limiting block corresponding to the outermost support foot cooperates with the side wall of the support foot, and the limiting block corresponding to the inner support foot cooperates with the limiting groove set at the hinge edge of the support foot.

[0017] Furthermore, there are two or more support feet, each of which is coaxially set through a hinge shaft and is embedded in a sequential manner from the inside to the outside. The movable plates corresponding to the support feet abut against each other along the same axis and share a common unlocking component. The limiting block corresponding to the outermost support foot cooperates with the side wall of the support foot, and the limiting block corresponding to the inner support foot cooperates with the limiting groove set at the hinge edge of the support foot.

[0018] Furthermore, there are two or more support feet, which are arranged side by side. The length of each support foot is not equal, and the number of limiting components corresponds to the number of support feet.

[0019] Furthermore, it also includes a cover plate, a limiting component and a positioning plate, all of which are mounted on the cover plate, and the support feet are hinged to the cover plate.

[0020] Another objective of this invention is to provide a posture-correcting study table with a support mechanism. The support mechanism is flexibly integrated into the main body of the panel, which can achieve uniform pressure distribution while maintaining the stability of the main body of the panel during use.

[0021] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0022] A posture-correcting study table with a support mechanism includes the aforementioned support mechanism and a panel body, wherein the support mechanism is disposed on the back of the panel body.

[0023] Furthermore, the number of support mechanisms is more than one set, each set containing two support mechanisms, and the two support mechanisms are symmetrically arranged on the back.

[0024] The beneficial effects of this utility model are as follows:

[0025] The support mechanism of this invention automatically locks the support foot by pushing the limiting component with an elastic element, and allows the support foot to rotate after being unlocked by moving the unlocking component, thus improving the stability of the support mechanism. The snap-fit ​​between the locking part and the locking groove enhances the locking effect of the support foot, thereby stably fixing the support foot at the current opening angle and preventing the support foot from loosening or shifting. Compared with the friction-based limiting method used in the prior art, this solution uses a physical blocking structure to ensure the stability of the support foot during use. In addition, the support mechanism of this invention cooperates with the panel body and is arranged symmetrically in groups, which enables the pressure on the panel body to be evenly distributed, resulting in better stability of the panel body during use.

[0054] The illustrated embodiments are provided to better illustrate the present invention, but the content of the present invention is not limited to the illustrated embodiments. Therefore, non-essential improvements and adjustments made to the implementation schemes by those skilled in the art based on the above-described content of the present invention still fall within the protection scope of the present invention.

[0055] Example 1

[0056] like Figures 1 to 6 As shown, a support mechanism includes a support foot 1, a limiting component 2, an unlocking component 3, and a positioning plate 4. The limiting component 2 includes an elastic element 201, a movable plate 202, a limiting block 203, and a connecting strip 204, wherein the elastic element 201 is a spring. Both ends of the elastic element 201 abut against the positioning plate 4 and the movable plate 202, respectively. The limiting block 203 is in close contact with the side wall of the support foot 1 and locks the support foot 1 in place after it is opened. The unlocking component 3 is fixed to the movable plate 202, and both ends of the connecting strip 204 are fixedly connected to the movable plate 202 and the limiting block 203, respectively. The support foot 1 is also provided with a hinge shaft 5 for rotating around it during the opening or closing of the support foot 1, and the position of the positioning plate 4 relative to the hinge shaft 5 remains fixed. After the support leg 1 is opened, the movable plate 202 moves along the axial direction of the hinge shaft 5 under the action of the elastic element 201, and locks the support leg 1 to a certain limit; when the unlocking element 3 is moved, the movable plate 202 moves in the opposite direction to release the locked limit state.

[0057] In this embodiment, the support mechanism has one support foot 1, and the limiting block 203 engages with the side wall of the support foot 1. When the support foot 1 is closed, the limiting block 203 abuts against the side wall of the support foot 1; when the support foot 1 is open, the limiting block 203 disengages from the side wall of the support foot 1 and locks the support foot 1 in place. Specifically, when the support foot 1 is closed, the limiting block 203 abuts against the side wall of the support foot 1; when the support foot 1 is open, the elastic element 201 pushes the movable plate 202 to move under the action of elastic force, and the movable plate 202 drives the limiting block 203 to move through the connecting strip 204. The limiting block 203 gradually disengages from the side wall of the support foot 1, locks the surface of the support foot 1, keeps the support foot 1 in the open state, and prevents it from rotating easily, thus achieving the locking and limiting of the support foot 1. In this embodiment, during the opening and closing of the support leg 1, the contact and disengagement action between the limiting block 203 and the side wall of the support leg 1 can quickly achieve the constraint and release of the support leg 1, and the locking and limiting effect is reliable, which greatly improves the stability of the support leg 1 during use.

[0058] In this embodiment, a slot 6 is provided on the side of the support foot 1 that mates with the limiting block 203. A snap-fit ​​part 7 matching the slot 6 is provided on the connecting strip 204. When the support foot 1 is opened, the snap-fit ​​part 7 is inserted into the slot 6 for limiting. When the support foot 1 is closed, the snap-fit ​​part 7 is separated from the slot 6, and the support foot 1 can rotate freely around the hinge axis 5. When it is necessary to open the support foot 1, the support foot 1 is manually pushed to rotate around the hinge axis 5. After the support foot 1 is opened, under the action of the elastic element 201, the movable plate 202 moves towards the slot 6, and the snap-fit ​​part 7 moves synchronously along the slot 6 under the drive of the connecting strip 204. Because the shapes of the snap-fit ​​part 7 and the slot 6 match, the snap-fit ​​part 7 is inserted into the slot 6 after moving along the slot 6, forming a tight snap-fit ​​engagement. The locking action of the locking part 7 and the locking groove 6 enhances the locking effect of the support foot 1, thereby stably fixing the support foot 1 at the current opening angle, making it less likely for the support foot 1 to loosen or shift, and ensuring the stability and safety of the support foot 1 during use.

[0059] In this embodiment, the movable plate 202 has an assembly groove 8. The elastic element 201 and the positioning plate 4 are both disposed within the assembly groove 8. One end of the elastic element 201 abuts against the positioning plate 4, and the other end abuts against the inner wall of the assembly groove 8. A limiting post 9 is also provided within the assembly groove 8, and the end of the elastic element 201 abutting against the inner wall of the assembly groove 8 is fitted onto the limiting post 9. The assembly groove 8 provides a stable installation space for the elastic element 201, and the limiting post 9 restricts the positional displacement of the elastic element 201 during extension and retraction, ensuring that the elastic element 201 can only extend and retract in a predetermined direction parallel to the hinge axis 5 when subjected to force. When the support leg 1 is closed, the elastic element 201 is in a compressed state. When the support leg 1 is opened, the elastic element 201 generates a force due to its restoring deformation. Because the elastic element 201 is disposed parallel to the hinge axis 5, and one end abuts against the inner wall of the assembly groove 8, the force of the restoring deformation directly pushes the movable plate 202 to move axially along the hinge axis 5. The movable plate 202 is connected to the limiting block 203 via the connecting strip 204, thereby allowing the movable plate 202 to move the limiting block 203, causing the limiting block 203 to lock onto the surface of the support foot 1, thus locking and limiting the support foot 1. In this embodiment, by opening an assembly groove 8 on the movable plate 202 and setting a limiting post 9 to install the elastic element 201, the stability of the installation and operation of the elastic element 201 is greatly improved.

[0060] In practical applications, the support mechanism in this embodiment can be directly used on existing posture-correcting learning desks, which include a panel body 11 and a support mechanism. The support mechanism is located on the back of the panel body 11, and there are one or more sets, each set containing two support mechanisms, symmetrically arranged on the back of each set. This symmetrical design of the support mechanisms allows them to share the pressure, ensuring even pressure distribution and maintaining the balance of the panel body 11 while preventing tilting or damage due to uneven force. Preferably, in this embodiment, the support mechanism on the back of the panel body 11 is a set.

[0061] Application Scenario 1: The support mechanism is detachably connected to the back of the panel body 11 via the cover plate 12.

[0062] In this application scenario, the support mechanism is first fixed to the cover plate 12, and then the cover plate 12 is detachably connected to the panel body 11, as follows: Figure 5 and Figure 6 As shown. The limiting component 2 and the positioning plate 4 in the support mechanism are set on the cover plate 12, and the support foot 1 is hinged to the cover plate 12. The cover plate 12 has an unlocking through hole 13, and the movable plate 202 is set on one side of the cover plate 12, and the side where the movable plate 202 is located cooperates with the panel body 11. One end of the unlocking component 3 is fixed to the movable plate 202, and the other end extends through the unlocking through hole 13 and hangs on the other side of the cover plate 12. When it is necessary to release the locked limiting state of the support foot 1, the user can directly apply external force to the suspended unlocking component 3, thereby driving the unlocking component 3 to move. Since the unlocking component 3 is fixedly connected to the movable plate 202, the movement of the movable plate 202 will drive the limiting block 203 to move in the opposite direction, so that the limiting block 203 no longer jams the support foot 1, thereby releasing the locked limiting state of the support foot 1. At this time, the support foot 1 can rotate around the hinge axis 5.

[0063] In actual assembly, the support mechanism is detachably connected to the panel body 11 via the cover plate 12. The detachable connection can be achieved by interference fit of the shaft holes. The back of the panel body 11 is provided with several positioning studs 15, and the inner surface of the cover plate 12 has several positioning shafts 16 (located on the back of the cover plate, such as...). Figure 4 The positioning axis 16 in the text is marked. Figure 5 , Figure 6 (Not marked in the text) The positioning shaft 16 and the positioning stud 15 have an interference fit in their inner diameters. During installation, the positioning shaft 16 is aligned with the positioning stud 15, and external force is used to force the positioning shaft 16 into the positioning stud 15, achieving a tight connection through the friction between the two. The cover plate 12 can also be fixed to the panel body 11 by snap-fit ​​or adhesive.

[0064] A sliding through hole 17 is formed in the movable plate 202 along the hinge axis 5. The diameter of the sliding through hole 17 is larger than the diameter of the positioning stud 15. One of the positioning shafts 16 on the cover passes into the sliding through hole 17 and then mates with the positioning stud 15. Since the two sides of the movable plate 202 are in contact with the cover plate 12 and the panel body 11 respectively, after one of the positioning studs 15 is aligned with the sliding through hole 17, the cover plate 12 can ensure that the movable plate 202 can slide along the hinge axis 5 without falling off the panel body 11.

[0065] Application Scenario 2: The support mechanism is directly hinged to the back of the panel body 11 via hinge shaft 5.

[0066] like Figure 22 As shown, in this application scenario, the support leg 1 is directly hinged to the panel body 11 of the posture-correcting learning table via the hinge shaft 5. The limiting component 2 and the positioning plate 4 in the support mechanism are mounted on the panel body 11, and the movable plate 202 is slidably mounted on the panel body 11. To ensure that the movable plate 202 does not easily detach within the panel body 11 and can slide smoothly, a positioning stud 15 is provided on the panel body 11, located below the self-tapping screw 18. A sliding through hole 17 is formed in the movable plate 202 along the hinge shaft 5 direction. The stud diameter is smaller than the through hole diameter, ensuring that the movable plate can slide axially along the hinge shaft, with smooth sliding and low friction, thus facilitating user movement. The self-tapping screw 18 is directly driven into the positioning stud 15. The head diameter of the self-tapping screw 18 is larger than the inner diameter of the sliding through hole 17, ensuring that the movable plate 202 can slide along the hinge shaft 5 direction without detaching from the panel body 11.

[0067] The movable plate 202 can also be slidably mounted on the panel body 11 via other connection methods. For example... Figure 23 , 24 As shown, a limiting frame is provided on the panel body 11, and the movable plate 202 is installed within the limiting frame. A dovetail groove can also be provided on the panel body 11, and a slider corresponding to the dovetail groove can be provided on the movable plate 202. The dovetail groove allows the movable plate 202 to slide axially along the hinge axis, ensuring the stability of the movable plate 202's sliding and preventing it from falling off the panel body 11. In this connection method, the movement range of the movable plate 202 is limited by the dovetail groove, the positioning plate 4, and the support foot 1. In actual design, other methods can also be used, as long as the corresponding function is achieved.

[0068] Example 2

[0069] The support mechanism structure in this embodiment is basically the same as that in Embodiment 1, except that the position of the limiting block 203 and the support foot 1 is different. The specific differences are as follows:

[0070] In Example 1, the limiting block 203 mates with the side wall of the support leg 1;

[0071] In this embodiment (Embodiment 2), the limiting block 203 is engaged with the middle of the hinged edge of the support leg 1.

[0072] like Figures 7 to 10 As shown, in this embodiment, a limiting groove 10 is also provided on the side of the support leg 1 that mates with the hinge shaft 5, and the end of the connecting strip 204 extends into the limiting groove 10. When the support leg 1 is closed, the limiting block 203 is located in the limiting groove 10 and abuts against the side wall of the limiting groove 10. After the support leg 1 is opened, the limiting block 203 disengages from the side wall of the limiting groove 10 and locks the support leg 1, thus locking it in place. Specifically, when the support leg 1 is closed, the limiting block 203 abuts against the side wall of the limiting groove 10. After the support leg 1 is opened, the elastic element 201 pushes the movable plate 202 to move under the action of elastic force, and the movable plate 202 drives the limiting block 203 to move through the connecting strip 204. The limiting block 203 gradually disengages from the side wall of the limiting groove 10, locks the surface of the support leg 1, keeps the support leg 1 in the open state, and prevents it from rotating easily, thus achieving the locking and limiting of the support leg 1. In this embodiment, during the opening and closing of the support leg 1, the contact and disengagement actions of the limiting block 203 with the side wall of the limiting groove 10 of the support leg 1 enable rapid constraint and release of the support leg 1, ensuring reliable locking and limiting effects and greatly improving the stability of the support leg 1 during use. Compared with Embodiment 1, this embodiment places the limiting block 203 in the middle of the hinge side of the support leg 1, which ensures more uniform force distribution on the support leg 1 during locking and limiting, thus improving the stability of the support mechanism.

[0073] The application scenario of this embodiment is exactly the same as that of the embodiment, that is, the support mechanism can be detachably connected to the back of the panel body 11 through the cover plate 12, or it can be directly hinged to the back of the panel body 11 through the hinge shaft 5, which will not be described in detail here.

[0074] In this embodiment, a slot 6 may also be provided on the side wall of the limiting groove 10 that cooperates with the limiting block 203 on the support foot 1, and a snap-fit ​​part 7 that matches the slot 6 may also be provided on the connecting strip 204, so as to enhance the locking effect of the support foot 1.

[0075] Example 3

[0076] Compared with Embodiment 1 and Embodiment 2, the number and arrangement of support feet 1 on each support mechanism are different in this embodiment.

[0077] like Figures 11 to 21As shown, in this embodiment, the support mechanism has two support feet 1, including an inner support foot 101 and an outer support foot 102 coaxially connected by a hinge shaft 5, and the two support feet 1 are distributed in an embedded manner. It should be noted that coaxial connection means that the inner support foot 101 and the outer support foot 102 share a hinge shaft 5, or different hinge shafts 5 can be used, and the center lines of the different hinge shafts 5 are located on the same straight line.

[0078] The inner support leg 101 is rectangular, and the outer support leg 102 has a U-shaped embedding groove 14 for accommodating the inner support leg 101. Both support legs 1 are equipped with corresponding limiting components 2. The limiting block 203 on the limiting component 2 corresponding to the outer support leg 102 engages with the side wall of the support leg 1, and the limiting block 203 on the limiting component 2 corresponding to the inner support leg 101 engages with the center of the hinge edge of the support leg 1. During installation, the outer support leg 102 fits onto the outside of the inner support leg 101 through the embedding groove 14, achieving a tight hinged connection. During unfolding, the two support legs 1 operate independently, and the design of the embedding groove 14 ensures the coordination of the unfolding action. This embodiment adopts a coaxial hinged and nested design for the two support legs 1, achieving the arrangement of two support points within a limited space. This ensures the stability of the support without occupying excessive space. Furthermore, the nesting method allows the support legs 1 to be compactly stored when not in use, facilitating carrying and storage.

[0079] The application scenario of this embodiment is exactly the same as that of embodiment 1. That is, the support mechanism can be detachably connected to the back of the panel body 11 through the cover plate 12, or it can be directly hinged to the back of the panel body 11 through the hinge shaft 5. This will not be described in detail here.

[0080] In practical applications, because the two support legs 1 are of different lengths, when different support legs 1 are opened, the outer support leg 102 will support the panel body 11 higher, forming a larger support angle with the panel body 11. The shorter inner support leg 101 will support the panel body 11 at a lower height, with a smaller support angle. By selecting to open different support legs 1, the support angle between the support legs 1 and the panel body 11 can be adjusted. In actual design, the two limiting components 2 can be controlled independently, or the movable plates 202 of the two limiting components 2 can be abutted together and controlled by a single unlocking component 3. This allows for locking the support legs individually and unlocking them together, improving operational convenience. The specific choice depends on the actual situation.

[0081] For ease of operation, in this embodiment, the two movable plates that cooperate with the inner support foot 101 and the outer support foot 102 are unlocked using the same unlocking component 3.

[0082] When the inner support foot 101 is opened, the outer support foot 102 is in the closed state, which will prevent the movement of the outer support foot 102 limiting component 2. At this time, only the inner support foot 101 limiting component 2 moves and locks the inner support foot 101. And moving the inner support foot 101 unlocking component 3 will unlock the inner support foot 101 and allow it to rotate.

[0083] When the outer support leg 102 is opened, the inner support leg 101 opens along with it, and the limiting components 2 corresponding to both support legs 1 move and lock their respective support legs 1. At this time, moving the inner support leg 101 unlocking component 3 pushes the inner support leg 101 movable plate 202, thereby causing the inner support leg 101 limiting block 203 to release the lock on the inner support leg 101, allowing the inner support leg 101 to rotate. Simultaneously, since the inner support leg 101 movable plate 202 and the outer support leg 102 movable plate 202 are adjacent, they also push the outer support leg 102 movable plate 202, thereby causing the outer support leg 102 limiting block 203 to release the lock on the outer support leg 102, allowing the outer support leg 102 to rotate.

[0084] like Figure 12 As shown, the two limiting components 2 have a split structure where the movable plates 202 of the two limiting components 2 can abut against each other, and are controlled by a single unlocking component 3. Protrusions 19 are provided on both sides of the inner wall of the embedding groove 14. When the outer support foot 102 is opened, the inner support foot 101 is also opened due to the protrusions 19 in the embedding groove 14. At this time, the corresponding elastic components 201 of the two components simultaneously push their respective movable plates 202 to move, thereby locking their respective support feet. Since the two movable plates 202 were previously designed to abut against each other, and since they moved the same distance, they are still abutting together after moving. At this point, moving the unlocking component 3 on the inner support foot 101 will cause the movable plate on the inner support foot 101 and the movable plate on the outer support foot 102 to move in the opposite direction, thus unlocking simultaneously. That is, the inner support foot 101 can be opened independently, and when the outer support foot 102 is opened, the inner support foot 101 also opens along with it.

[0085] Example 4

[0086] Compared with Embodiment 1 and Embodiment 2, the number of support feet 1 is different in the application scenario of this embodiment.

[0087] The application scenario of this embodiment is exactly the same as that of embodiment 1. That is, the support mechanism can be detachably connected to the back of the panel body 11 through the cover plate 12, or it can be directly hinged to the back of the panel body 11 through the hinge shaft 5. This will not be described in detail here.

[0088] In this embodiment, the panel body 11 has two sets of support mechanisms, namely a first group and a second group. Each group contains two support mechanisms, and the two support mechanisms in each group are symmetrically arranged on the back side. The support mechanisms in the first and second groups are arranged side by side. Because they are arranged side by side, the support mechanisms located on the same side of the panel body 11 can share the same hinge shaft 5 or use independent hinge shafts 5. The support mechanisms within the same group are completely identical, but the lengths of the support legs 1 in the support mechanisms of the two groups are different. Users can choose to open different numbers and lengths of support legs 1 according to their actual needs.

[0089] In other embodiments, the number of support mechanisms on the panel body 11 can be two or more groups. Each group can be arranged side by side or dispersed, ensuring that the two support mechanisms in each group are symmetrically arranged on the panel body 11.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
