Description
TECHNICAL FIELD
[0001] The application relates to the technical field of motor rotation and stator, and particularly relates to a heavy spring force adjusting mechanism. BACKGROUND
[0002] Currently, the spring force adjusting mechanisms existing in the market mainly achieve the adjusting by rotating a screw rod with a gear groove. The traditional adjusting mode is widely used due to its simple structure and performs well in many light load application environments. However, with the development of modern mechanical equipment towards large-scale and high load, the traditional spring force adjusting mechanism cannot meet the demand of high strength operation, especially higher requirements for equipment stability and durability are put forward in heavy industrial production lines.
[0003] Some solutions in the prior art: a screw rod with a gear is rotated by using a manual or electric tool, and the adjusting is achieved by changing the position of a support member engaged with the screw rod. The cost is low and the maintenance is easy; however, the defects are also very obvious, that is, the screw thread is easily damaged or even broken under a large load, which seriously affects the service life and safety. The spring deformation amount is indirectly controlled by using a hydraulic or pneumatic piston movement to adjust. Although a larger adjusting range and higher precision can be provided, the complex control system increases the overall cost and brings inconvenience to daily maintenance.
[0004] Both of the above two common types of spring force adjusting mechanisms have certain limitations. In addition, these methods usually only focus on function implementation and ignore the concern for component wear under long-term operation, which not only limits the service life of the product, but also increases the maintenance frequency and cost of the user. CONTENT OF THE INVENTION
[0005] In order to avoid the problem of damage of the gear groove of the key components in the traditional spring force adjusting mechanism, especially the screw rod head, caused by excessive spring tension, the application provides a heavy spring force adjusting mechanism.
[0006] The application provides a heavy spring force adjusting mechanism, which adopts the following technical scheme:
[0007] The heavy spring force adjusting mechanism comprises a first cover plate, a second cover plate, a spring member and an adjusting member, the first cover plate is combined with the second cover plate to form an adjusting box, the spring member and the adjusting member are respectively installed in the adjusting box, one end of the spring member is connected with the second cover plate, and the other end is connected with the adjusting member; the adjusting member has a sliding part and an adjusting part, the sliding part is slidingly installed on the second cover plate, and one end of the spring member is connected with the sliding part; one end of the adjusting part is rotationally connected with the second cover plate, the middle part penetrates through the sliding part and is rotationally connected with the sliding part, and the other end is arranged in the adjusting box and is rotationally connected with the adjusting box.
[0008] By adopting the above technical scheme, the connection strength and stability of the spring force adjusting mechanism are improved. The first cover plate and the second cover plate combine to form an adjusting box, protecting the internal components from external environmental influences and prolonging the service life. The spring member is connected to the second cover plate at one end and to the adjusting member at the other end, ensuring that the spring remains stable during adjustment and preventing component damage due to excessive tension. The heavy-duty spring force adjusting mechanism effectively improves the stability and reliability of spring force adjustment. Specifically, the sliding portion is slidingly installed on the second cover plate, allowing one end of the spring member to move with the sliding block, thereby enabling more flexible and precise spring force adjustment. The adjusting portion is rotationally connected to the second cover plate at one end, passes through the sliding portion, and is rotationally connected thereto. This design not only improves the overall rigidity of the structure but also ensures smoother and more stable relative movement between components during adjustment. The other end is designed to pass through the adjusting box and be rotationally connected to the adjusting box, further enhancing the stability and durability of the entire system and avoiding the common problem of gear slot damage in traditional screw pushing methods.
[0009] Preferably, a support member is provided on the second cover plate, which is fixedly installed on the second cover plate, and the spring member is arranged in close proximity to the support member.
[0010] By adopting the above technical scheme, the support member can effectively enhance the connection strength and stability between the spring member and the second cover plate, prevent structural damage or failure due to excessive spring tension, and improve the working reliability and service life of the entire adjusting mechanism.
[0011] Preferably, a driving member is installed in the adjusting box, which is rotationally installed on the second cover plate. One end of the driving member abuts the spring member, and the driving member has a pushing portion that abuts one end of the spring member.
[0012] By adopting the above technical scheme, the driving member can effectively push one end of the spring member, achieving precise adjustment of the spring force. At the same time, the rotational installation of the driving member makes its movement more stable, reducing wear and tear caused by mechanical friction and improving the service life and reliability of the entire adjusting mechanism. In addition, the design of the pushing portion ensures good contact with the spring member, avoiding adjustment errors caused by poor contact.
[0013] Preferably, a limiting member is provided at the connection between the spring member and the pushing portion. The limiting member is slidingly installed on the second cover plate, and the pushing portion passes through the limiting member. The limiting member has a guide portion, and the pushing portion moves along the guide portion.
[0014] By adopting the above technical scheme, the limiting member can effectively limit the relative position between the spring member and the pushing portion, preventing them from shifting or coming apart during operation and improving the overall stability and reliability of the device. The design of the guide portion allows the pushing portion to move smoothly along a predetermined path, further enhancing the accuracy and smoothness of the adjustment process.
[0015] Preferably, the second cover plate is provided with a buffer, the buffer is fixedly installed on the second cover plate, and an output end of the buffer abuts against the limiting piece.
[0016] By adopting the above technical scheme, the impact and vibration generated by the limiting piece during movement can be effectively reduced, and the stability and service life of the entire adjusting mechanism are improved. Specifically, the buffer can provide effective buffering when the limiting piece is subjected to a large force, preventing the limiting piece from being damaged due to instantaneous impact, and also reducing stress concentration of the spring piece, further enhancing the reliability of the system.
[0017] Preferably, the second cover plate is provided with a lower recess, and the driving piece is located in the lower recess.
[0018] By adopting the above technical scheme, the driving piece is arranged in the lower recess of the second cover plate, which can effectively prevent the driving piece from colliding or rubbing with external objects, protect the driving piece from damage, and prolong the service life. At the same time, the design of the lower recess can also make the overall structure of the adjusting mechanism more compact, improving the aesthetics and space utilization.
[0019] Preferably, the sliding part is provided with a plurality of hanging parts, and one end of the spring piece is clamped with the plurality of hanging parts.
[0020] By adopting the above technical scheme, multi-point connection between the spring piece and the sliding part can be achieved, improving the reliability and stability of the connection and avoiding the uneven stress problem that may be caused by a single connection point. At the same time, the multi-point connection mode also increases the adjustment range, making the spring force adjustment more flexible and accurate.
[0021] In summary, the present application includes at least one of the following beneficial technical effects:
[0022] 1. By changing the structure of the adjusting part to a screw pushing a sliding block to move, the connection strength and stability are improved, effectively preventing the problem of damage to the screw head due to uneven stress in traditional design;

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings, and the described embodiments are only possible technical implementations of the present application, not all possible implementations. Those skilled in the art can obtain other embodiments by combining the embodiments of the present application without creative labor, and these embodiments are also within the protection scope of the present application.
[0031] The inventor of the present application found that the existing spring force adjusting mechanism is very easy to fail when the spring tension is too large, because the gear groove of the screw head is easily damaged. Therefore, the present application mainly adopts the following heavy spring force adjusting mechanism, which comprises a first cover plate 1, a second cover plate 11, a spring member 2 and an adjusting member 3. The first cover plate 1 is combined with the second cover plate 11 to form an adjusting box. The spring member 2 and the adjusting member 3 are respectively installed in the adjusting box. One end of the spring member 2 is connected with the second cover plate 11, and the other end is connected with the adjusting member 3, thereby improving the connection strength and stability.
[0032] The heavy spring force adjusting mechanism provided by the embodiment of the present application, as shown in Figure 1 and Figure 2 , comprises a first cover plate 1, a second cover plate 11, a spring member 2 and an adjusting member 3. The first cover plate 1 is combined with the second cover plate 11 to form an adjusting box. The spring member 2 and the adjusting member 3 are respectively installed in the adjusting box. One end of the spring member 2 is connected with the second cover plate 11, and the other end is connected with the adjusting member 3, thereby improving the connection strength and stability. The problem of easy damage of the screw head in the prior art is solved.
[0033] As shown in Figure 2 and Figure 3Specifically, the adjusting piece 3 comprises a sliding part 31 and an adjusting part 32. The sliding part 31 is slidingly installed on the second cover plate 11, and one end of the spring piece 2 is connected with the sliding part 31. The adjusting part 32 is rotationally connected with the second cover plate 11 at one end, penetrates through the sliding part 31 at the middle part and is rotationally connected with the sliding part 31, and is rotationally connected with the adjusting box at the other end. This design makes the adjusting part 32 freely rotate within a certain range, so as to better adapt to different use environments.
[0034] In the embodiment, the sliding part 31 is specifically a spring frame, which is made of a metal material, such as stainless steel or aluminum alloy, so as to improve the wear resistance and corrosion resistance. The surface of the sliding part 31 is also polished to reduce the friction resistance.
[0035] In the embodiment, the adjusting part 32 is specifically an adjusting screw, which is threadedly connected with the spring frame; and a variety of materials, such as high-strength steel or titanium alloy, are adopted, which have higher strength and toughness and can maintain stable performance under high load conditions.
[0036] Referring to Figure 2 and Figure 3 Specifically, the second cover plate 11 is provided with a supporting piece 110, which is fixedly installed on the second cover plate 11 and the spring piece 2 is arranged close to the supporting piece 110. The supporting piece 110 provides additional support to prevent the spring piece 2 from deviating when subjected to force. In the embodiment, the supporting piece 110 is specifically a spring supporting base, which can be made of a metal material, such as a steel plate or cast iron, so as to enhance the rigidity and stability.
[0037] Specifically, the adjusting box is provided with a driving piece 4, which is rotationally installed on the second cover plate 11. One end of the driving piece 4 abuts against the spring piece 2, and the driving piece 4 has a pushing part 41 which abuts against one end of the spring piece 2. The driving piece 4 is used to push the spring piece 2 to move under the action of external driving force, so as to support the opening and closing of some furniture or support the reset movement of the furniture, etc. by using the reaction force of the spring piece 2.
[0038] In the embodiment, the driving piece 4 is specifically a cam, which can be made of a metal material, such as a steel plate or cast iron, so as to enhance the rigidity and stability; and the pushing part 41 is specifically a push rod, which is rotationally installed on the cam.
[0039] Referring to Figure 2 and Figure 3Specifically, the spring member 2 is connected with the pushing part 41, and a limiting part 5 is arranged at the connecting position of the spring member 2 and the pushing part 41. The limiting part 5 is slidingly arranged on the second cover plate 11, the pushing part 41 penetrates through the limiting part 5, and the limiting part 5 is provided with a guide part 51, and the pushing part 41 moves along the guide part 51. The limiting part 5 limits the movement range of the pushing part 41, so as to avoid damage caused by excessive compression of the spring member 2. The limiting part 5 is specifically a limiting plate, and the limiting plate can be made of a metal material, such as copper or aluminum, so as to ensure the durability. The guide part 51 is specifically an arc-shaped through slot arranged on the limiting part 5.
[0040] Specifically, the second cover plate 11 is provided with a buffer part 6, and the buffer part 6 is fixedly arranged on the second cover plate 11. The output end of the buffer part 6 abuts against the limiting part 5. The buffer part 6 absorbs excessive energy in an extreme case, so as to protect the system from damage. The buffer part 6 is specifically an oil cylinder, which can provide a constant damping force in a wide range of travel. In other embodiments, the buffer part 6 can be made of an elastic material such as rubber or silicone. These materials have excellent energy absorption characteristics and can effectively alleviate the impact force.
[0041] Specifically, the second cover plate 11 is provided with a lower recess 111, and the driving part 4 is located in the lower recess 111. The design of the lower recess 111 helps to concentrate the force and reduce unnecessary stress distribution, thereby improving the overall stability of the system. The shape of the lower recess 111 can be adjusted according to actual needs. In this embodiment, the lower recess 111 is specifically an arc-shaped lower recess. In other embodiments, the lower recess 111 can be circular, square or polygonal, so as to adapt to different installation spaces and mechanical requirements.
[0042] Referring to Figure 3 Specifically, the sliding part 31 is provided with a plurality of hanging parts 33, and one end of the spring member 2 is clamped with the plurality of hanging parts 33. The hanging part 33 is specifically a hanging rod. The design of the hanging rod hanging part 33 enables the spring member 2 to be conveniently installed and disassembled, thereby facilitating maintenance and replacement. In this embodiment, the hanging part 33 is a pin. In other embodiments, the hanging part 33 can also be in the form of a hook or a clamp. The specific form depends on the requirements of the actual application scene.
[0043] The implementation principle of this embodiment is as follows:
[0044] By changing the traditional gear groove adjustment mode to the screw sliding block movement mode, the connection strength and stability are greatly improved. The ingenious design of the sliding part 31 and the adjusting part 32 makes the adjustment process more smooth and accurate. By rotating the adjusting part 32, one end of the adjusting part 32 is rotationally connected with the support 110, and then the adjusting part 32 is stably rotated in the adjusting box under the limitation of the first cover plate 1 and the second cover plate 11, thereby driving the sliding part 31 to slide relative to the second cover plate 11, so as to drive one end of the spring member 2 to stretch or contract, thereby reducing the damage risk caused by uneven stress. In addition, the introduction of auxiliary components such as the support 110, the limiting part 5 and the buffer 6 further enhances the reliability and service life of the system. Overall, the embodiment not only solves the problems existing in the prior art, but also optimizes and innovates in many aspects, and improves the overall performance and user experience.
[0045] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalent ones; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application.
