Abstract

The utility model discloses a disk spring lamination used by a diaphragm type pressure switch, and the radial cross section of the disk spring lamination is of a shape of truncated cone without bottom surface. The utility model is characterized in that a reinforcement portion is arranged on the bottom of the disk spring lamination. The disk spring lamination used by a diaphragm type pressure switch of the utility model comprises a reinforcement portion on the bottom of the disk spring lamination to increase the intensity of the disk spring lamination, effectively avoid the bottom cracking problem of the disk spring lamination and raise the service life of the disk spring lamination through the force transmission by the reinforcement portion.

Description

The dish-shaped shell fragment that a kind of diaphragm type pressure switch is used

Technical field

The utility model relates to diaphragm type pressure switch technical field, the dish-shaped shell fragment that particularly a kind of diaphragm type pressure switch is used.

Background technology

The dish-shaped shell fragment that existing diaphragm type pressure switch is used, its structure is referring to shown in Figure 1, the radial section of this dish shell fragment 1 is the truncated cone shape of a no bottom surface, in use find, the root discontinuity of dish shell fragment 1, cause dish-shaped shell fragment 1 pressure transient, its bottom is very easy to cracking, poor durability.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of root stressed evenly at the existing above-mentioned technical problem of existing dish-shaped shell fragment, the dish-shaped shell fragment that the diaphragm type pressure switch that pressure stability and bottom are not easy to ftracture is used.

Technical problem to be solved in the utility model can be achieved through the following technical solutions:

The dish-shaped shell fragment that a kind of diaphragm type pressure switch is used, the radial section of this dish shell fragment is the truncated cone shape of a no bottom surface, it is characterized in that, the frustum of a cone conical surface of described dish-shaped shell fragment is divided into two sections of upper and lowers, its middle and lower part outwards turns down, and forms a folding muscle in the junction on bottom and top.

Described bottom outwards turnover extremely becomes 90 ° of positions with the axis of described dish-shaped shell fragment.

The dish-shaped shell fragment that the utility model diaphragm type pressure switch is used is by being divided into the frustum of a cone conical surface two sections of upper and lowers, and the bottom outwards turns down, form a folding muscle in the junction on bottom and top, the folding muscle can be divided equally the bottom of dish-shaped shell fragment especially root is stressed like this, make the pressure of dish-shaped shell fragment more stable, take place the useful life of having improved dish-shaped shell fragment in the problem that has prevented dish-shaped shell fragment root cracking effectively.

Fig. 1 is the structural representation of existing dish-shaped shell fragment.

Fig. 2 is the structural representation of the utility model dish shell fragment embodiment 1.

Fig. 3 is the structural representation of the utility model dish shell fragment embodiment 2.

Embodiment

Below be specific embodiment of the utility model, and in conjunction with the accompanying drawings, the technical solution of the utility model be further described, but the utility model is not limited to these embodiment.

Referring to Fig. 2, the dish-shaped shell fragment that a kind of diaphragm type pressure switch is used, this dish shell fragment 100 radial section be the truncated cone shape of a no bottom surface, the frustum of a cone conical surface of dish shell fragment is divided into 120 two sections of top 110 and bottoms, its middle and lower part 120 outwards turns down, and 120 form a folding muscle 130 with the junction on top 110 in the bottom.

Referring to Fig. 3, the dish-shaped shell fragment that a kind of diaphragm type pressure switch is used, this dish shell fragment 100 radial section be the truncated cone shape of a no bottom surface, the frustum of a cone conical surface of dish shell fragment is divided into 120 two sections of top 110 and bottoms, its middle and lower part 120 outwards turnover to 140 one-tenths 90 ° of positions of axis of dish-shaped shell fragment 100,120 form one with the junction on top 110 and roll over muscle 130 in the bottom.

Specific embodiment described herein only is to illustrating that the utility model spirit is done.The utility model person of ordinary skill in the field can to described specifically be that example makes various modifications, replenishes or adopt similar mode to substitute, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.

Claims

1. dish-shaped shell fragment that the diaphragm type pressure switch is used, the radial section of this dish shell fragment is the truncated cone shape of a no bottom surface, it is characterized in that, the frustum of a cone conical surface of described dish-shaped shell fragment is divided into two sections of upper and lowers, its middle and lower part outwards turns down, and forms a folding muscle in the junction on bottom and top.
