Description

Technical Field

[0001] The utility model belongs to the technical field of valves, and in particular relates to an elastic handle for a valve. Background Art

[0002] In the field of valves, the installation structure of the main handle and the auxiliary handle is crucial to the operating efficiency, safety and reliability of the valve. However, the existing design has some significant shortcomings and deficiencies, which directly affect the operating efficiency, safety and reliability of the valve.

[0003] First, the traditional main handle and sub-handle installation structure usually uses a pin and a hole to connect the main handle and the sub-handle. This design requires a hole to be drilled between the handles and connected by a pin. The manufacturing process of this installation method is relatively complicated, including steps such as drilling holes and processing pins, which increases production costs and production cycles. At the same time, the reliability of this connection method may be affected by manufacturing accuracy and material quality, and there is a risk of loose locking, which may cause the valve to open or close accidentally during operation, causing equipment damage or personal injury.

[0004] Secondly, the traditional installation structure may limit the design and size of the main handle and auxiliary handle, affecting the appearance and user experience of the valve. Since the position and size of the pin and the overhead hole need to be considered, the design of the handle may be limited and cannot meet the user's needs for beautiful appearance and comfortable operation. In addition, due to the existence of the handle connection structure, the weight and volume of the handle may be increased, affecting the overall design and installation of the valve.

[0005] In addition, the pins and openings in the traditional installation structure may be worn and loose. After long-term use, the matching accuracy of the pins and openings may decrease, resulting in a decrease in the locking performance of the handle, or even loosening. This will not only affect the operational stability and reliability of the valve, but may also increase the cost and workload of maintenance.

[0006] In addition, the design of the traditional installation structure may not be flexible enough to meet the needs of different users for the handle installation method. In some special scenarios, users may need to choose different handle installation methods according to actual conditions, but the traditional connection structure may not meet these needs, resulting in a poor user experience.

[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0028] In order to solve the problems of complex manufacturing process, loose locking, limited design, wear and looseness of the current valve main handle and auxiliary handle installation structure, the utility model provides a valve handle and a valve. The handle is designed to be pin-connected, which simplifies the assembly process, improves efficiency, has a good anti-falling effect, and has a stable structure, thereby comprehensively optimizing the reliability of valve operation and user experience. In order to further illustrate the structure of the utility model, the detailed description is as follows in conjunction with the attached drawings:

[0029] Embodiment 1

[0030] See also Figure 1-Figure 3 , an elastic handle for a valve, comprising a main handle 1, a secondary handle 2, an elliptical groove 3 and a pin head 4.

[0031] The main handle has two sides forming support parts 1-1. The front end of the main handle is mounted on the valve shaft to apply torque to the valve shaft. Specifically, the main handle is an injection molded component with a cross section of an inverted U shape, a groove formed at the bottom, and two sides forming the support parts.

[0032] The auxiliary handle is arranged below the main handle. The front end of the auxiliary handle is provided with a locking tooth portion 2-1 which is combined with the valve locking ratchet 5. When the locking tooth portion is combined with the locking ratchet, the main handle and the auxiliary handle form a scissor-shaped structure which is circumferentially locked. When disengaged, torque can be applied. The above structure and working principle belong to the prior art.

[0033] The oval groove symmetrically arranged on the left and right is arranged on the supporting part of the main handle. In the present embodiment, the oval groove is an asymmetrical structure, and the oval groove is provided with an oval part 1-2 combined with the pin head, a front edge part 1-3 and a rear edge part 1-4 formed by extending the side of the oval part, the front edge part is arranged close to the front end of the main handle, and the upper end of the front edge part is higher than the rear edge part. Further, the front edge part is connected to the upper wall of the main handle to form a closed structure, and an opening is formed between the upper end of the rear edge part and the upper wall of the main handle for the pin head to pass through. The pin head can be assembled into the oval groove from this opening, and the front edge part positions the assembled pin head and ensures the stability of the structure after assembly.

[0034] Two symmetrical pins are respectively arranged on both sides of the auxiliary handle and assembled in the elliptical groove. Specifically, the auxiliary handle is an injection molded component, and the pins are cylindrical structures formed on both sides of the auxiliary handle and integrated with the auxiliary handle. The auxiliary handle as a whole can be embedded in the groove at the bottom of the main handle.

[0035] The elastic component is installed between the main handle and the auxiliary handle, and the elastic component exerts an elastic force to open the rear part of the scissor-shaped structure formed by the main handle and the auxiliary handle. In this embodiment, the elastic component is a spring 6, the upper end of which is pressed against the rear end of the main handle, and the lower end of which is pressed against the rear end of the auxiliary handle. In this embodiment, the angle of the spring is designed so that the axis of the spring and the front axis of the auxiliary handle form an obtuse angle design, ensuring that in addition to exerting an elastic force to open the auxiliary handle in the scissor-shaped structure, the spring has a component force on the auxiliary handle toward the front end, which makes the pin head always press against the front edge of the elliptical groove, further preventing the pin head from detaching from the mouth, and improving the structural stability.

[0036] In this structure, the main handle and the auxiliary handle are integrally formed during the manufacturing process with an elliptical groove and a pin head for assembly. No additional accessories are required during the assembly process, and the assembly can be completed quickly by simply docking. Compared with existing structures, this structure has many advantages such as high manufacturing efficiency, low cost and stability.

[0037] Furthermore, the lower part of the main handle is provided with a fulcrum part 1-5, and the fulcrum part and the elastic component are respectively located on both sides of the elliptical groove. In this embodiment, the fulcrum part is a convex ridge structure that is provided on the upper wall of the main handle and protrudes downward, and the convex ridge structure is integrally injection molded with the main handle. Under the elastic force of the elastic component, the upper part of the sub-handle presses against the convex ridge structure. Specifically, when the handle is not assembled on the valve, the fulcrum part of the convex ridge structure serves as a supporting structure of the sub-handle on the opposite side of the elastic component. Under the elastic action of the elastic component, pressure is applied to the end of the sub-handle, so that the two pin heads on the sub-handle always have pressure pressed against the bottom of the elliptical groove, so that the elastic handle in the form of this assembly forms a structurally stable integral component when not assembled, and the various components will not fall off and separate.

Figure 4 As known to those skilled in the art, the valve includes a valve body 7, a valve cover, a valve core 8 and a valve seat, and the main and auxiliary handle installation structures described in Example 1 serve as the actuator of the valve. The main handle is connected to the valve stem that controls the movement of the valve core, and the front end of the auxiliary handle is connected to the valve cover with a locking tooth locking mechanism.
