Description

Technical Field

[0001] This utility model relates to the field of cabinet dynamic gear technology, specifically to a structure of cabinet dynamic gear and pulley. Background Technology

[0002] The design of a cabinet with dynamic gears and pulleys can be applied to many pieces of furniture or equipment, such as automatic opening and closing or motion control systems for drawers and doors. This structure combines the working principles of gears and pulleys, and is typically used to achieve smooth and precise movement.

[0003] In existing technologies, most cabinet-type dynamic gears and pulleys lack effective positioning and fixing measures. These components are prone to loosening and displacement during use, leading to structural instability, affecting overall performance and lifespan, and increasing maintenance and replacement costs. Furthermore, the connection to the cabinet is not secure enough; under certain external forces or after prolonged use, structural loosening may occur, causing malfunctions and even safety hazards, failing to meet the requirements for long-term stable use. Therefore, we have introduced a new structure for cabinet dynamic gears and pulleys. Utility Model Content

[0004] The purpose of this utility model is to provide a structure for a cabinet dynamic gear and pulley to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a structure of a cabinet dynamic gear and pulley, comprising: a fixing plate, positioning pin A and positioning pin B;

[0006] A fixed shaft is provided on one side of the surface of the fixed plate, and two sets of pulleys are fitted on the surface of the fixed shaft. The surface of the fixed plate is provided with a slide rail for sliding the pulleys. The pulleys roll along the slide rail, and the friction is reduced by rolling friction, so that the cabinet can be pushed and pulled smoothly.

[0007] The positioning pin A is disposed on one side of the fixing plate. The surface of the positioning pin A is provided with a fixing block A. The positioning pin A is used to fix the fixing block A. The surface of the fixing block A is provided with a gear component. The surface of the gear component is meshed with teeth, and the teeth are connected to the bottom of the fixing plate.

[0008] The positioning pin B is located at the bottom of the fixing plate, below the positioning pin A. The surface of the positioning pin B is provided with a fixing block B, and the positioning pin B is used to fix the fixing block B.

[0009] The surface of the fixing plate is provided with a mounting mechanism, and the mounting gear is fixed to one side of the fixing plate by the positioning pin C of the mounting mechanism.

[0010] Preferably, the positioning pin C is connected to the bottom side of the fixing plate, and a gear is attached to the surface of the positioning pin C. The bottom of the fixing plate is provided with a screw below the fixing block B, and the screw is used to adjust the height.

[0011] Preferably, the fixed plate is provided with a bearing on its side, and a flange shaft is provided on one side of the bearing. The bearing can effectively reduce the friction when the flange shaft rotates, so that the flange shaft can rotate smoothly.

[0012] Preferably, the surface of the fixing plate is provided with a contact connecting plate, and a contact body is connected to one side of the contact connecting plate.

[0013] Preferably, the side of the fixing plate is provided with a frame above the flange shaft, one bottom side of the frame is connected to a door back panel, and the other bottom side of the fixing plate is connected to a door glass.

[0014] Preferably, the side of the fixing plate is connected to a limiting plate, and the side of the limiting plate is connected to an anti-collision buffer pad. The anti-collision buffer pad can absorb collision energy, reduce the impact of the collision on the cabinet and other items, and play a role in buffering and protection.

[0015] Preferably, a nameplate is connected to the side of the fixing plate, and a countersunk screw is connected to the top of the fixing plate. The nameplate can be used to identify the model, brand, parameters and other information of the cabinet, so as to facilitate user identification and management. The countersunk screw on the top of the fixing plate is used to firmly install the fixing plate in the corresponding position of the cabinet, ensuring the stability of the entire structure. The countersunk design can make the screw head flush with the surface of the fixing plate, without affecting the appearance of the cabinet and the normal operation of other components.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) By using positioning pins A, B and C in conjunction with corresponding fixing blocks A, B and gears, the installation of each component on the fixing plate is more stable, effectively preventing the components from loosening and shifting, ensuring the stability of the entire cabinet's dynamic gear and pulley structure during long-term use. The countersunk screws firmly install the fixing plate on the cabinet, further enhancing the connection strength between the entire structure and the cabinet, so that the structure can remain stable under various forces, reducing the failures and safety hazards caused by structural loosening.

[0018] (2) By setting two sets of pulleys and cooperating with the fixed shaft, the cabinet can move smoothly through rolling friction during the pushing and pulling process, which reduces the resistance of friction to the movement of the cabinet, reduces the force required to push the cabinet, and makes the operation easier and more convenient. At the same time, it also reduces the wear caused by friction and extends the service life of pulleys and related components. The combination of bearings and flange shaft effectively reduces the friction between rotating parts, making the rotation of flange shaft more stable, ensuring the efficiency and stability of power transmission, and thus ensuring the stable rotation of the gear, enabling the cabinet to achieve precise and smooth dynamic movement, such as automatic opening and closing of doors, lifting and lowering, etc., which are smoother and improve the user experience.

[0019] (3) Through the design of the limit plate and the anti-collision buffer pad, effective protection measures are provided for the cabinet. The limit plate can limit the range of movement of the cabinet and prevent the cabinet from being damaged due to excessive movement or colliding with surrounding objects. The anti-collision buffer pad absorbs the collision energy when a collision occurs, reduces the impact force on the cabinet and other items, prevents scratches and dents on the surface of the cabinet and damage to internal components, and also protects the safety of surrounding items, improving the safety and reliability of the cabinet.

[0020] (4) Through the meshing transmission of pulleys and gears, precise control of the movement of cabinet components can be achieved. Since gear transmission has a precise transmission ratio, it can accurately convert the sliding distance of the pulley into the rotation angle of the gear, thereby precisely controlling the displacement of related components. In high-end furniture or display cabinets, this precise control can make the opening and closing of the door smoother and more accurate, avoiding problems such as jamming and collision that may be caused by inaccurate movement, improving the user experience, and also protecting the cabinet structure and internal items.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a cabinet dynamic gear and pulley structure, including: a fixing plate 1, a fixing shaft 4 is provided on one side of the surface of the fixing plate 1, a pulley 3 is sleeved on the surface of the fixing shaft 4, and the number of pulleys 3 is two sets, and a slide rail 11 for sliding the pulleys 3 is provided on the surface of the fixing plate 1;

[0029] Positioning pin A9 is provided on one side of fixing plate 1. Fixing block A8 is provided on the surface of positioning pin A9. Gear component 25 is provided on the surface of fixing block A8. Gear component 25 has teeth 24 meshing on its surface and the teeth 24 are connected to the bottom of fixing plate 1.

[0030] Positioning pin B13 is located at the bottom of the fixing plate 1, below positioning pin A9, and a fixing block B14 is provided on the surface of positioning pin B13.

[0031] The surface of the fixing plate 1 is provided with an installation mechanism, and the mounting gear 2 is fixed to one side of the fixing plate 1 by the positioning pin C10 of the installation mechanism.

[0032] The positioning pin C10 is connected to the bottom side of the fixing plate 1, and the gear 2 is connected to the surface of the positioning pin C10. The bottom of the fixing plate 1 is provided with a screw 12 below the fixing block B14. The screw 12 is used to adjust the height.

[0033] The fixed plate 1 has a bearing 15 on its side, and a flange shaft 16 is provided on one side of the bearing 15. The bearing 15 can effectively reduce the friction when the flange shaft 16 rotates, so that the flange shaft 16 can rotate smoothly.

[0034] The surface of the fixing plate 1 is provided with a contact connecting plate 20, and a contact body 7 is connected to one side of the contact connecting plate 20.

[0035] The side of the fixing plate 1 is provided with a frame 17 above the flange shaft 16. A door back panel 18 is connected to one bottom side of the frame 17, and a door glass 19 is connected to the other bottom side of the fixing plate 1.

[0036] The side of the fixed plate 1 is connected to a limiting plate 21, and the side of the limiting plate 21 is connected to an anti-collision buffer pad 22. The anti-collision buffer pad 22 can absorb collision energy, reduce the impact of the collision on the cabinet and other items, and play a role in buffering and protection.

[0037] The side of the fixing plate 1 is connected to a nameplate 5, and the top of the fixing plate 1 is connected to a countersunk screw 6. The nameplate 5 can be used to identify the model, brand, parameters and other information of the cabinet, so as to facilitate user identification and management. The countersunk screw 6 on the top of the fixing plate 1 is used to firmly install the fixing plate 1 in the corresponding position of the cabinet to ensure the stability of the entire structure. The countersunk design can make the screw head flush with the surface of the fixing plate 1, without affecting the appearance of the cabinet and the normal operation of other components.

[0038] Specifically, during use, two sets of pulleys 3 are fitted on the surface of the fixed shaft 4 on the fixed plate 1. The pulleys 3 can rotate freely around the fixed shaft 4. During the movement of the cabinet, the pulleys 3 roll along the slide rail 11, and the friction is reduced by rolling friction, so that the cabinet can be pushed and pulled smoothly.

[0039] Positioning pins A9 and B13 are respectively set on one side and bottom of the fixing plate 1. The fixing blocks A8 and B14 on their surfaces play the role of positioning and auxiliary fixing, ensuring that the relative positions of each component on the fixing plate 1 are accurate and stable, preventing the components from shifting or shaking during use, thereby ensuring the reliability and stability of the entire structure.

[0040] The positioning pin C10 is located on one side of the bottom of the fixing plate 1. The mounting gear 2 is fixed on the fixing plate 1 by the mounting mechanism. The mounting gear 2 can rotate on the surface of the positioning pin C10. Under the drive of external power, the mounting gear 2 rotates, providing power support for the dynamic function of the cabinet and achieving a specific movement effect.

[0041] The bearing 15 on the side of the fixed plate 1 and the flange shaft 16 on one side cooperate. The bearing 15 can effectively reduce the friction when the flange shaft 16 rotates, so that the flange shaft 16 can rotate smoothly and can withstand certain axial and radial loads.

[0042] The contact connection plate 20 on the surface of the fixed plate 1 is connected to the contact body 7. The contact body 7 may be connected to the circuit system inside the cabinet. When the cabinet is in motion, the contact body 7 contacts or senses other components to realize the conduction, disconnection or signal transmission of the circuit, thereby controlling some functions of the cabinet, such as lighting, door opening and closing actions, safety protection, etc., providing a basis for the intelligent operation of the cabinet.

[0043] The limiting plate 21 and the anti-collision buffer pad 22 connected to the side of the fixed plate 1, when the cabinet moves to a certain position, the limiting plate 21 plays the role of limiting the range of movement of the cabinet, preventing the cabinet from moving excessively and causing damage. When the cabinet collides with other objects, the anti-collision buffer pad 22 can absorb the collision energy, reduce the impact of the collision on the cabinet and other items, play a buffering and protection role, extend the service life of the cabinet and related components, and also improve the safety of use.

[0044] The nameplate 5 on the side of the fixing plate 1 can be used to identify the model, brand, parameters and other information of the cabinet, so as to facilitate user identification and management. The countersunk screw 6 on the top of the fixing plate 1 is used to firmly install the fixing plate 1 in the corresponding position of the cabinet, ensuring the stability of the entire structure. The countersunk design can make the screw head flush with the surface of the fixing plate 1, without affecting the appearance of the cabinet and the normal operation of other components.

[0045] When an external force pushes the pulley 3 to slide on the slide rail 11, since the pulley 3 is sleeved on the fixed shaft 4, and the fixed shaft 4 is connected to the fixed plate 1, and the teeth 24 at the bottom of the fixed plate 1 mesh with the gear component 25 on the surface of the fixed block A8, the movement of the pulley 3 will transmit force to the teeth 24 through the fixed plate 1, thereby causing the gear component 25 to rotate. For example, when the pulley 3 slides to the left, the teeth 24 will apply a force to the left to the gear component 25. According to the gear transmission principle, the gear component 25 will rotate clockwise around its axis (assuming the gear is a common external meshing gear and is standardly installed); conversely, when the pulley 3 slides to the right, the gear component 25 will rotate counterclockwise.

[0046] The rotation of gear 25 can be controlled by other components connected to it, such as the gear 2, which may have some kind of transmission connection (indirectly connected through components such as positioning pin C10), thereby affecting the movement state of the gear 2 and thus affecting related mechanisms (such as controlling the opening, closing, or movement of the door glass 19 or the door back panel 18 to achieve dynamic operation of the cabinet door). At the same time, the rotation of gear 25 may also be linked with components such as contact connection plate 20. When the gear rotates to a specific position, it can trigger the on / off action of the contact body 7 to achieve electrical control or signal transmission functions, such as playing a role in the control of the cabinet's internal lighting system or other electronic equipment.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
