Description

Mushroom head button

Technical Field

The utility model belongs to the technical field of locomotive electrical apparatus, concretely relates to mushroom head button.

Background

The push-button switch is installed on the console of the locomotive, is a common control electrical component, and is a switch which is usually used for switching on or off a control circuit so as to achieve the purpose of controlling the operation of a motor or other electrical equipment. The common button switch is mainly used for functions of sudden stop, starting, stopping, inching, resetting and the like, and is an important control element on the locomotive. The button switch has a simple structure and is convenient to install, but the mushroom head button has low qualification rate when mushroom head parts are produced, and unqualified parts are difficult to sort; meanwhile, the button switch is easy to have the phenomena of clamping stagnation and inflexibility in the using process, and the existing mushroom head button is improved in order to solve the problem.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a first button of mushroom to reduce the production degree of difficulty of first part of mushroom and improve its part qualification rate, make button switch no longer appear jamming, inflexible problem in the use simultaneously.

The utility model adopts the technical proposal that: a mushroom head button comprises a mushroom cap, a mushroom body is sleeved on the mushroom cap; the mushroom body is provided with a hook which hooks the mushroom cover to be sleeved with the mushroom cover; the mushroom cover is provided with a groove, and the hook is embedded into the groove to enable the mushroom cover to be sleeved with the mushroom body; the mushroom cover is internally provided with spline bulges, the number of the spline bulges is at least two, the included angle of the adjacent spline bulges is 30 degrees, and the included angle between the spline bulges and the horizontal direction is 15 degrees.

The utility model is also characterized in that,

the inner side of the mushroom cover is also provided with a glue storage groove for accommodating the sleeving part of the mushroom body and the groove and injecting glue for fixation.

The utility model has the advantages that:

the utility model discloses a mushroom head button is injection moulding's working of plastics, and the mushroom head is formed by mushroom lid and the equipment of mushroom body. When the mushroom cover is assembled with the mushroom body, the inner wall of the mushroom cover is coated with bonding glue, then the mushroom body is inserted into the mushroom cover, wherein the groove on the mushroom cover is inserted into the hook of the mushroom body, the mushroom cover is also provided with the spline protrusions, and the spline type structure reduces the friction surface of the mushroom head and other matching parts of the button switch, eliminates the possible clamping stagnation or inflexible problem, improves the qualification rate of parts, and reduces the risk of clamping stagnation of the button switch.

Drawings

Fig. 1 is a schematic structural view of a mushroom head button of the present invention;

FIG. 2 is a cross-sectional view of the mushroom cap of FIG. 1;

FIG. 3 is a schematic structural view of the mushroom body of FIG. 1;

fig. 4 is a bottom view of the mushroom cap of fig. 1.

In the figure, 1, a mushroom cover, 1-1, a groove, 1-2, a spline bulge, 1-3, a glue storage groove, 2, a mushroom body and 2-1, a hook are arranged.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

A mushroom head button, as shown in figure 1, comprises a mushroom cover 1, and a mushroom body 2 is sleeved on the mushroom cover 1.

As shown in figure 2, a groove 1-1 is arranged at the sleeving part of the mushroom cover 1 and the mushroom body 2, the groove 1-1 is connected with the mushroom body 2, and a glue storage groove 1-3 is also arranged at the inner side of the mushroom cover 1 and used for accommodating the sleeving part of the mushroom body 2 and the groove 1-1 and injecting glue for fixation.

As shown in figure 3, the mushroom body 2 is provided with a hook 2-1, and the hook 2-1 is inserted into the groove 1-1, so that the mushroom cover 1 and the mushroom body 2 are sleeved together.

As shown in fig. 4, spline protrusions 1-2 are further arranged inside the mushroom cap 1, at least two spline protrusions 1-2 are arranged, the included angle between every two adjacent spline protrusions 1-2 is 30 degrees, and the included angle between each spline protrusion and the horizontal direction is 15 degrees.

The utility model discloses a first button of mushroom to current improves to reduce the production degree of difficulty of the first part of mushroom and improve its part qualification rate, make button switch no longer appear jamming, inflexible problem in the use simultaneously. The moving part of the original mushroom head button is an injection molding plastic part and is a whole, and the mushroom head is an elongated part, so that the diameter and the length are large, and the thin rod of the mushroom head is easy to incline in the injection molding process, so that the phenomenon of switch clamping stagnation can be generated in the using process. The utility model divides the mushroom head into two parts of mushroom cover and mushroom body to reduce the production difficulty; simultaneously change the mushroom head and button switch body cooperation part the mushroom lid inner circle into spline formula cooperation by the cylinder, reduce the friction, this is that this is for making the switch not produce the jamming when the installation uses for the protruding and horizontal direction contained angle of spline is 15.
