Abstract

The utility model provides a roller type travel switch with springs. The roller type travel switch comprises a roller, an arch spring arranged below the roller, a first spring arranged in a push rod, a second spring arranged below the arch spring and connected with the exterior of the push rod, a small roller arranged below the push rod, an escapement rod arranged under the small roller, a connecting rod connected with the escapement rod, a movable contact arranged below the escapement rod and penetrated by the connecting rod, and fixed contacts arranged at two sides of the movable contact. The roller type travel switch with the springs is advantaged by simple operation, high safety performance, long service lifetime, and high stability.

Description

A kind of rolling wheel type travel switch with spring
Technical field
the utility model relates to a kind of rolling wheel type travel switch with spring.
Background technology
1880, along with the electric light of Edison invented, opened the first page of switch developing history chapter.Switch develops into today, has experienced variation repeatedly, has also realized the leap of technology.What it maintained is I, you, our living safety, so do not allow to look down upon switch.China's Electric lamp switch for household production history can be traced back to GE in 1913 in Shanghai incorporation.1914, the gloomy money a large bell note electric industry machinery plant that establishes in Shanghai of money a large bell, from then on Chinese have started the electric road of oneself.
along with continuous change and improvement, original traditional switch body has revealed various weak points.On selecting materials, traditional switch must adopt fixing material, because the unicity of material has caused the limitation in the design to the manufacturer.Most of traditional switch is because the structural design imperfection is easy to occur the safety problems such as electric leakage.And some Multifunctional intelligent switchs on the market, although security performance compares, traditional switch is high, can adopt the high-tech transducer to be controlled, if also have in use the equipment of other belt sensor near switch, just be very easy to produce the phase mutual interference between transducer, affect its stability, and, because principle and working method complexity are easy to occur damaging, reduced useful life.
Summary of the invention
the technical problems to be solved in the utility model just be to provide a kind of simple to operate, security performance is high, long service life, and the strong rolling wheel type travel switch with spring of stability.
for addressing the above problem, the utility model adopts following technical scheme: a kind of rolling wheel type travel switch with spring, comprise roller, and be arranged on the arc spring of roller below, and the push rod be connected with arc spring, and be arranged on the first spring in push rod, and be arranged on arc spring below, with outside the second spring be connected of push rod, and be arranged on the trundle of push rod below, and be arranged on the escapement bar of trundle below, and the connecting rod be connected with the escapement bar, and be arranged on escapement bar below, be connected the moving contact that bar runs through connection, and be arranged on the fixed contact on moving contact both sides.
as preferably, described fixed contact has 2 points, lays respectively at the right and left of moving contact.
the beneficial effects of the utility model are: because the rolling wheel type travel switch with spring is provided with contact, no matter it at which kind of state as long as reaching certain value, the operating physical force of contact just can be operated, simple to operate and leaky can not occur, security performance is high, adopt the mechanical type principle of roller, push rod and spring to guarantee its stability, can not be subject to the impact of neighboring sensors.
The accompanying drawing explanation
by the description of a preferred embodiment of the present invention being carried out below in conjunction with accompanying drawing, it is clearer that technical scheme of the present invention and technique effect thereof will become, and easy to understand more.Wherein:
the structure chart that Fig. 1 is a kind of rolling wheel type travel switch with spring of the utility model.
reference numeral is as follows:
arc spring 1, roller 2, the first springs 3, the second spring 4, trundle 5, escapement bar 6, fixed contact 7, moving contact 8, connecting rod 9, push rod 10.
Embodiment
below with reference to appended accompanying drawing, the preferred embodiments of the present invention are described.Need to indicate, wherein " left side ", " right side " are only in order to be convenient to by reference to the accompanying drawings the purpose of illustration and description, to be not limited only to this.
the first embodiment
consult shown in Fig. 1, the utility model adopts following technical scheme: a kind of rolling wheel type travel switch with spring, comprise roller 2, and be arranged on the arc spring 1 of roller 2 belows, and the push rod 10 be connected with arc spring 1, and be arranged on the first spring 3 in push rod 10, and be arranged on arc spring 1 below, with outside the second spring 4 be connected of push rod 10, and be arranged on the trundle 5 of push rod 10 belows, and be arranged on the escapement bar 6 of trundle 5 belows, and the connecting rod 9 be connected with escapement bar 6, and be arranged on escapement bar 6 belows, be connected the moving contact 8 that bar 9 runs through connection, and be arranged on the fixed contact 7 on moving contact 8 both sides.
described fixed contact 7 has 2 points, lays respectively at the right and left of moving contact 8.Do the direction motion between described escapement bar 6 and trundle 5.
the beneficial effects of the utility model are: because the rolling wheel type travel switch with spring is provided with contact, no matter it at which kind of state as long as reaching certain value, the operating physical force of contact just can be operated, simple to operate and leaky can not occur, security performance is high, adopt the mechanical type principle of roller, push rod and spring to guarantee its stability, can not be subject to the impact of neighboring sensors.
for the person of ordinary skill in the field, along with the development of technology, the present invention's design can realize by different way.Embodiments of the present invention are not limited in embodiment described above, and can be changed within the scope of the claims.
