New description: 【New technical field】——This creation is a pressure switch, especially an actuator that can be installed in various liquid e-paths, by which the top of the liquid pressure pushes against the lever to drive the micro switch. The design of the pressure switch structure. [Prior Art] At present, there are several pressure switch structures available for driving an actuator of a micro switch, such as an electromagnetic switch, an area switch, etc., and the above switches are mainly installed in various liquid tubes. The road is controlled by the liquid pressure to control the start or close of the micro switch to be widely used in various industrial applications, reducing unnecessary waste, and greatly improving the economic efficiency of the operator. However, the common types of pressure switch structures are still generally unable to drive the switch quickly. When applied to various liquid pipelines, it is actually not suitable as a reference for the operator to accurately and quickly drive the switching ratio. There are also some pressure-opening relationships through complex structural design to achieve the function of quickly driving the switch, but it further leads to a relative increase in the overall manufacturing cost of the pressure switch, which creates a burden on the operator. [New content] In order to overcome the deficiencies of the prior art, the present invention provides a pressure switch structure that is more compact and can be quickly driven. The technical solution adopted by the present invention to solve the technical problem is: a pressure switch comprising a body, a contact group and a cover plate, wherein the seat body forms a receiving groove having a recess, the seat body being The two sides of the M295332 are respectively provided with a socket hole and a connecting hole for connecting the accommodating groove; the contact group includes a socket portion connected to the socket hole, and the adjusting block is screwed at the __ end of the socket portion, and the other end The inner part is provided with an upper and lower pressing block for pressing the lever portion of the elastic member up and down, and an adapter portion for sealing the sheet at one end and the sleeve portion; the cover plate is detachable to the seat body Set the block on the slot. Compared with the prior known pressure switch, the present invention has the following beneficial effects: 1 • 1. Rapid driving: When the pressure switch is installed in various liquid pipelines, the liquid pressure is greater than the elastic component, and the thrust is reversed. The thin plate of the portion is matched with the change of the relative position of the elastic member disposed on the contact portion, so that the actuator of the micro switch can be driven by the contact portion to achieve the pressure switch that is rapidly driven. The structure is simplified: the pressure switch is transmitted through the base body. The combination of the simple components such as the contact group and the cover plate can achieve the purpose of rapidly driving the actuator of the micro switch and reduce the manufacturing cost of the pressure switch.

The same can be used for the inlet pipe 11 in the accommodating groove 11 of the seat body 1 (Fig. Ding) and effluent & (pictured not) position setting socket hole 3 and connecting hole (3) 'where the socket hole 13 - end is set as inner screw hole 130, thereby, when the creative pressure switch application is connected to various In the case of the liquid line, it is screwed to the socket 21 of the contact and assembly. 1 Referring to Fig. 3, the socket body 21 which can be screwed by the socket 10 of the seat body 10 when the pressure switch is actually used is extended by the inner hole 243 of the M295332 locking portion 242. The internal thread 244 is combined with various liquid lines (not shown) to allow liquid to flow into the inner hole 243 of the locking portion 242 via various liquid lines, and is driven by the hydraulic pressure generated when the liquid flows. When the sheet 241 at the front end of the external thread portion 240 of the joint portion 24 is displaced, the sheet 241 is protected by the film 2322 on the concave surface 2320 of the cover body 232 and the cushion 2324 which is restrained by a pad body 2323 when displaced. The sheet 241 is prevented from being worn and broken during displacement. φ and the other end of the shank portion 23 extends the threaded end 2310 of the rod body 231, and is screwed by the socket block 2311, and can be locked by the socket block 2311 as shown in FIG. 3 and the fourth and fifth figures. The sensor 120 of the micro switch 12 in the housing 1 accommodates the slot 11 and forms a contact state for being activated by the liquid pressure or not being closed by the pressure. Please refer to FIG. 4, in the process of using the liquid pressure to touch and replate, when the liquid flows in from the inner hole 243 of the locking portion 242, the hydraulic pressure generated by the liquid flow is greater than the rod body. When the outer edge φ is elastic 70 pieces 235 elastic force, the sheet 241 at the front end of the external thread portion 240 of the hydraulic pushing adapter portion 24 is displaced, and when the sheet 241 is displaced, the circular block 23 located on the central buried hole 2321 of the cover body 232 The displacement is also reversed. At this time, the sensing block H12 of the touch micro switch 12 can be activated by the socket block 2311 screwed at the other end of the rod body 231, and as shown in FIG. 5, when the locking portion 242 is bored. When the hydraulic pressure of the 243 towel is not continuously pushed and is smaller than the elastic force of the elastic member 235 at the outer edge of the rod body 231, the round block 230 located at the center of the cover body 232 is also displaced relative to the original position, and is borrowed from the circular block. The 23〇-side first block 234 abuts against the cover 232, so that the rod 231 is in phase
