Description

Technical Field

[0001] The present application relates to the technical field of pressure testing devices, and in particular to a digital display sensor type pressure testing instrument. Background Art

[0002] With the development of railways, especially the development of high-speed railway transportation, the safety requirements for transportation are getting higher and higher. In railway maintenance units, professional railway personnel check and maintain railway signal equipment on both sides of the rails every day. For the contact switches in railway switch machines, personnel are required to test their contact pressure; the pressure tester on the market includes a detection part, a grip part and a display part. The display part is located at the upper end of the grip part, and the detection part is located at the lower end of the grip part. When testing the contacts of the switch machine, the detection part is located between the moving contact and the static contact, and then the pressure is displayed on the display part in the form of a numerical value. Since the outer shell of the display part is integrally connected to the outer shell of the grip part, when it is necessary to record the value, the staff needs to bend down and lower their heads to read the value, which reduces the work efficiency of testing the switch machine pressure.

According to different testing environments, the transfer ball is rotated in the connecting seat to rotate the display part relative to the holding part, so that the display part is tilted. Then the lower end of the holding part is brought into contact with the detection part of the switch machine. Since the display screen of the display part faces the staff, it is convenient to record the test data, which improves the working efficiency of testing the switch machine pressure;

[0014] 2. The connecting seat includes a fixing seat and a splicing seat. When the display part and the grip part are installed, the transfer ball is placed in the fixing seat, and then one side of the splicing seat and one side of the fixing seat are fixed to each other, so that the transfer ball is located between the fixing seat and the splicing seat, thereby fixing the display part to the upper end of the grip part, improving the installation efficiency of the display part and the grip part;

[0015] 3. The side wall of the transfer ball has a damping plate, and under the action of the damping plate, the friction between the transfer ball and the connecting seat is increased, so that the display part can only rotate under the action of external force. BRIEF DESCRIPTION OF THE DRAWINGS
