Description

Technical Field

[0001] The utility model relates to the field of electrical technology, in particular to a rotary switch. Background Art

[0002] The rotary switch makes the static contact component cooperate with the dynamic contact component by turning the handle to form a conduction or disconnection effect. The rotary switch has multiple gears, and each gear corresponds to a different working state. In the prior art, the handle of the rotary switch or the accommodating chamber of the rotary switch is provided with a number of gear slots. For example, when the gear slot is located on the handle, the copper sleeve cooperates with the spring, one end of the spring extends into the copper sleeve, and the other end of the spring is against the accommodating chamber, and the copper sleeve slides on the gear slot to form a gear restriction effect; or the gear slot is located on the inner wall of the accommodating chamber, and the handle drives the copper sleeve to rotate. The two copper sleeves are symmetrically arranged, one end of the spring extends into one of the copper sleeves, and the other end of the spring extends into the other copper sleeve. When the handle is rotated, it drives the copper sleeve to move, so that the copper sleeve slides on the gear slot. In addition, there is also a method of using steel balls and springs to form a steel ball sliding on the gear slot.

[0003] The problem with the above structure is that it requires the coordination of multiple parts, and during the assembly process, it is necessary to overcome the restoring force of the spring. If it is not installed properly or is loosened prematurely, the copper sleeve is likely to pop off, resulting in low installation efficiency. Utility Model Content

[0041] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] Example 1

[0043] This embodiment provides a rotary switch, as shown in the attached Figure 1-7 As shown, including:

[0044] The body 11 is provided with a receiving cavity 111. The body 11 includes a base 12 and an upper cover 13, which can be snap-connected or bolted or connected in other ways, and the base 12 and the upper cover 13 cooperate to form the receiving cavity 111.

[0045] The handle 14 is accommodated in the accommodating cavity 111. The handle 14 is partially located in the accommodating cavity 111, and the rest of the handle 14 extends to the outside through the upper cover 13. The operator can achieve the driving effect through the handle 14. The handle 14 cooperates with the contact assembly 15 in the accommodating cavity 111 to form a connection or disconnection effect. This is the prior art. In this embodiment, the handle 14 is rotatably arranged relative to the accommodating cavity 111, that is, the handle 14 rotates to achieve the action of the contact assembly 15.

[0046] The handle 14 or the inner wall of the accommodating cavity 111 is provided with a plurality of gear slots 16, and the elastic member can cooperate with the handle 14 to form a gear limiting effect, and the elastic member 17 can also cooperate with the inner wall of the accommodating cavity 111 to form a gear limiting effect. Here, the gear slots 16 are distributed in a circular array, and the tops of two adjacent gear slots 16 are connected to form a ring-shaped wave shape. Here, the number of gear slots 16 can be adjusted according to actual needs.

[0047] The elastic member 17 is accommodated in the accommodating cavity 111. Compared with the prior art, the elastic member 17 is a single component, and is not a combination of two or more independent components. The elastic member 17 is provided with an elastic portion 171, which is a deformable structure, and the elastic portion 171 slides on the gear slot 16. The elastic portion 171 is directly arranged on the elastic member 17. Compared with the prior art method of combining two components, this structure can achieve the gear limit effect with only one component, and the installation efficiency of one component is higher. Moreover, there is no need to consider overcoming the elastic force of the spring, making the installation more convenient.

[0048] Specifically, as attached Figure 1-5As shown, the handle 14 is provided with a plurality of gear slots 16. Since the handle 14 is also provided with a protrusion 141 that cooperates with the contact assembly 15, the gear slots 16 and the protrusions 141 are staggered in the vertical direction, that is, the handle 14 is located in the part of the accommodating cavity 111, and the protrusions 141 and the gear slots 16 are staggered in the vertical direction. The protrusions 141 can be located at the top and the gear slots 16 can be located at the bottom, or the protrusions 141 can be located at the bottom and the gear slots 16 can be located at the top. Those skilled in the art can select a suitable structure according to actual needs. In this embodiment, only the gear slot 16 is located at the bottom as an example for description. The elastic member 17 is connected and fixed to the accommodating cavity 111, and the elastic member 17 is connected and fixed to the bottom surface of the accommodating cavity 111. By setting the gear slot 16 on the handle 14, the elastic member 17 is fixedly matched with the accommodating cavity 111, so that the elastic part 171 slides on the gear slot 16, forming a gear limiting effect. In addition, the elastic member 17 can also be linked with the handle 14, and the inner wall of the accommodating cavity 111 is provided with a gear slot 16, and the elastic part 171 can also achieve the effect of sliding on the gear slot 16. For example, the elastic member 17 is an inverted U-shaped structure, and its top passes through the handle 14 to form a linkage effect with the handle 14. The two lower ends of the elastic member 17 are provided with elastic parts 171, and the elastic parts 171 can also be inclined, so that the elastic part 171 cooperates with the gear slot 16 to form a linkage effect.

[0049] Specifically, as attached Figure 1-5 As shown, the elastic member 17 and the accommodating cavity 111 are connected by one of the positioning structure, the snap-fit ​​structure, the bolt structure and the interference fit, or a combination of two or more of them. The elastic member 17 can be matched with the accommodating cavity 111 in different connection and fixing methods to form a connection and fixing effect. Those skilled in the art can adjust and select different fixing methods according to actual needs. For example, the elastic member 17 can be connected and fixed to the bottom surface of the accommodating cavity 111 by bolts; or the elastic member 17 can be connected and fixed to the bottom surface of the accommodating cavity 111 by a snap-fit ​​structure; or a combination of multiple structures can be used to increase the connection and fixing effect between the elastic member 17 and the accommodating cavity 111.

[0050] Specifically, as attached Figure 1-5As shown, the elastic member 17 also includes a main body 172, and the main body 172 is connected to the elastic part 171. In this embodiment, the number of elastic parts 171 is two, and the two elastic parts 171 are respectively connected to the two ends of the main body 172. The two elastic parts 171 are symmetrically arranged, that is, a U-shaped structure is formed. In this embodiment, the main body 172 is connected and fixed to the bottom surface of the accommodating cavity 111. Here, the main body 172 and the bottom surface of the accommodating cavity 111 are connected by one of the positioning structure, the snap-on structure, the bolt structure, and the interference fit, or a combination of two or more thereof. The connection between the main body 172 and the elastic part 171 realizes the overall structure of the elastic member 17, making processing, installation, and fixing more convenient.

[0051] Specifically, as attached Figure 1-5 As shown, one of the main body 172 and the accommodating cavity 111 is provided with a positioning column 18, and the other of the main body 172 and the accommodating cavity 111 is provided with a positioning groove 19 that cooperates with the positioning column 18. The cooperation between the positioning column 18 and the positioning groove 19 forms a horizontal limit fixation of the elastic member 17 and the accommodating cavity 111. When the main body 172 is provided with a positioning column 18, the accommodating cavity 111 is provided with a positioning groove 19; conversely, when the main body 172 is provided with a positioning groove 19, the accommodating cavity 111 is provided with a positioning column 18. In this embodiment, the accommodating cavity 111 is provided with a positioning column 18, and the main body 172 is provided with a positioning groove 19. The positioning column 18 cooperates with the positioning groove 19 to form a horizontal limit fixation of the elastic member 17 in the accommodating cavity 111. The number of positioning columns 18 here can be selected according to actual needs, and can be one, two, or more.

[0052] Specifically, as attached Figure 1-5 As shown, the contact assembly 15 is also included, and the contact assembly 15 is accommodated in the accommodating cavity 111, and the contact assembly 15 is fitted with the main body 172. Through the arrangement of the contact assembly 15, the limiting effect of the main body 172 is formed, so that the elastic member 17 is better fixed in the accommodating cavity 111 as a whole, and the gear matching effect is better achieved. Here, the contact assembly 15 includes a static contact assembly 151 and a dynamic contact assembly 152, which can be the static contact assembly 151 and the main body 172, or the dynamic contact assembly 152 and the main body 172. In this embodiment, only the top surface of the static contact assembly 151 and the main body 172 are fitted as an example. Through the top surface of the static contact assembly 151 and the main body 172, the fixing effect of the main body 172 in the vertical direction is formed. At the same time, through the cooperation between the positioning column 18 and the positioning groove 19, the elastic member 17 can be better located in the accommodating cavity 111. At this time, the main body 172 is static, but the elastic part 171 can be deformed.

[0053] Specifically, as attached Figure 1-5As shown, the elastic part 171 and the main body 172 are integrally formed. The integrally formed setting makes the processing of the elastic member 17 more convenient. Here, the elastic member 17 as a whole can be made of plastic material, and the processing of the elastic member 17 is formed by integral injection molding. In addition, the elastic part 171 and the main body 172 can also be a split structure. For example, the elastic part 171 is an elastic structure formed of metal, and is integrally injected with the main body 172 to form a component, or it can also be spliced ​​and fixed to form a component.

[0054] Specifically, as attached Figure 1-5 As shown, the elastic part 171 is connected with the main body 172 to form an angle, which is an acute angle. The angle setting of the elastic part 171 makes the elastic force of the elastic part 171 better and better cooperates with the gear slot 16. The angle between the elastic part 171 and the main body 172 here can be adjusted according to actual needs. It should also be noted that when the elastic member 17 cooperates with the handle 14, the angle formed by the elastic part 171 and the main body 172 is an obtuse angle, that is, an outer eight structure is formed.

[0055] Specifically, as attached Figure 1-5 As shown, a gap is provided between the elastic part 171 and the bottom surface of the accommodating cavity 111. The provision of the gap forms a suspended effect of the elastic part 171, so that the elastic matching effect is better.

[0056] Specifically, the side of the elastic part 171 facing the gear slot 16 is an arc surface. The setting of the arc surface allows the elastic part 171 to slide more smoothly when it cooperates with the gear slot 16, and it can also be a beveled surface. The gear slot 16 is also set as an arc surface. In this embodiment, the end of the elastic part 171 facing the gear slot 16 is preferably cylindrical, so the side surface will form an arc surface effect.

[0057] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
