Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of clothes drying rod accessories, and in particular relates to a grounding guide fixing mechanism. Background Art
[0002] Electromagnetic starter, also known as "magnetic starter". It is an electrical appliance that directly starts the motor and is composed of an electromagnetic AC contactor, a thermal relay and a button. It has undervoltage and overload protection.
[0003] As an important safety switching device, the electromagnetic starter itself must also be independently grounded. The internal switch components and various switch parts all need to be grounded. However, as a large switch, the grounding of the movable mechanism inside the equipment needs to be achieved by plugging in, that is, the grounding of the internal switch structure of the electromagnetic starter is achieved by connecting the movable connector with the fixed socket; that is, the grounding busbar is connected to a fixed position, and the movable switch mechanism needs to be connected to the grounding busbar when it is energized. If the connection is unstable, it will inevitably affect the normal operation of the electromagnetic starter, especially as the number of uses increases, there is a problem of loosening of the grounding connector. Utility Model Content
[0004] In view of this, the utility model provides a grounding guide fixing mechanism to solve the above-mentioned problems described in the background technology.
[0005] In order to achieve the above object, the utility model is implemented through the following technical solutions:
[0006] The utility model provides a grounding guide fixing mechanism, comprising a sleeve-shaped connecting sleeve connected to a grounding main line, the connecting sleeve comprising a fixing part, a plurality of elastic parts connected to the fixing part through a deformation part, the plurality of elastic parts are evenly distributed along the circumference of the fixing part, and a groove part is formed between adjacent elastic parts; a groove is arranged on the outer side close to the end of the elastic part, and the grooves on the plurality of elastic parts form an annular groove part; an annular spring is sleeved on the annular groove part, the annular spring is in a contracted state, and causes the ends of the plurality of elastic parts to be slightly displaced toward the center of a circle.
[0007] In the above-mentioned grounding guide fixing mechanism, as a preferred solution, an inclined surface is provided inside the distal end of the elastic portion, and the inclined surfaces of the plurality of elastic portions constitute the guide portion.
[0008] In the above-mentioned grounding guide fixing mechanism, as a preferred solution, the deformation portion is an inwardly concave annular structure, and the deformation portion is completely opened at the lower end of the elastic portion.
[0009] The utility model provides a grounding guide fixing mechanism, which has the following beneficial effects:
[0010] The grounding guide fixing mechanism provided by the utility model realizes the connection between the grounding head of the movable part and the grounding busbar by designing a special connecting sleeve. The elastic part at the front end of the connecting sleeve cooperates with the annular spring so that the connecting sleeve can firmly fix the connecting head, which can effectively avoid the problem of loose connection between the two under working conditions. The front end of the elastic part is provided with a guiding part, which enables the connecting sleeve to smoothly dock with the grounding connecting head of the movable part.

[0014] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0015] Exemplary embodiments of the present invention are described in detail with reference to the following drawings.
[0016] The meanings of the serial numbers in the figure are as follows: 1 is a fixing part, 2 is a deformation part, 3 is an elastic part, 4 is a groove part, 5 is an annular groove part, 6 is a guide part, and 7 is an annular spring.
[0017] The following describes exemplary embodiments of the present invention in combination with specific circumstances:
[0018] Example 1: Combination Figure 1-Figure 3As shown, the utility model provides a grounding guide fixing mechanism, including a sleeve-shaped connecting sleeve connected to the grounding main line, the connecting sleeve including a fixing portion 1, a plurality of elastic portions 3 connected to the fixing portion 1 through a deformation portion 2, the plurality of elastic portions 3 are evenly distributed along the circumference of the fixing portion 1, and a groove portion 4 is formed between adjacent elastic portions 3; the length ratio of the elastic portion 3 to the fixing portion 1 is 4:1. A groove is provided on the outer side near the end of the elastic portion 3, and the grooves on the plurality of elastic portions 3 form an annular groove portion 5; an annular spring 7 is sleeved on the annular groove portion 5, the annular spring 7 is in a contracted state, and causes the ends of the plurality of elastic portions 3 to slightly displace toward the center of the connecting sleeve. The above structural design enables the connecting sleeve to firmly fix the connector under the action of the annular spring after the connector is connected, thereby achieving a relatively stable connection and ensuring the effectiveness of the grounding.
[0019] The inner side of the end of the elastic part 3 is provided with an inclined surface, and the inclined surfaces of the multiple elastic parts 3 constitute the guide part 6, which is an annular horn cavity structure. The deformation part 2 is an inwardly concave annular structure, and the deformation part 2 is completely opened at the lower end of the elastic part 3.
[0020] Working principle: After the electrical components inside the electromagnetic starter are installed (usually they are installed outside the shell door, and the pulley with the electrical components installed is pushed to the working position through the built-in slide rail structure), the grounding head of the electrical component is pushed into the shell along with the pulley. At this time, the grounding connector will be inserted into the connecting sleeve. Under the action of the annular spring, the elastic part of the connecting sleeve can firmly hold the grounding connector; when it is necessary to repair the electrical components inside the electromagnetic starter, disconnect the main power supply, just pull out the pulley, the grounding connector can be removed from the connecting sleeve, and the grounding circuit can be disconnected.
[0021] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
[0022] The above specific examples are used to illustrate the principle and implementation mode of the present invention. The description of the above embodiments is only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation mode and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
