Problems solved by technology
However, the test equipment is bulky, and it is generally necessary to rotate the device under test to achieve the purpose of tightening
For large-sized devices under test, it is difficult and time-consuming to rotate. Therefore, the traditional connection joints have a negative impact on test efficiency.

Embodiment Construction
[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0027] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.
[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as...

The invention relates to a hydrostatic pressure test connection joint, which comprises a first joint and a second joint. Specifically, the first joint includes a first shell, a first interface and a hollow column. The outer edge of the first shell is provided with at least two buckles. The second joint includes a second shell, a second interface and a stepped hole. The second shell is provided with clamping grooves projecting from the edge of the second shell, and the clamping grooves are clamped with the buckles. During test, firstly the first joint and the second joint are respectively communicated with a to-be-tested device and test equipment, then the first joint and the second joint are brought into butt joint so as to make the hollow column fittingly sleeved in the stepped hole, and finally the buckles and the clamping grooves are clamped to realize butt joint of the to-be-tested device and test equipment. By means of the hydrostatic pressure test connection joint, butt joint of the to-be-tested device and test equipment can be realized only through clamping of the buckles and the clamping grooves after butt joint of the first joint and the second joint without screwing up screw threads by rotating the to-be-tested device and test equipment. Therefore, the test efficiency is greatly improved.
Description
【Technical field】 [0001] The invention relates to a connection joint, in particular to a hydrostatic pressure test connection joint. 【Background technique】 [0002] In the field of professional lighting, explosion-proof lamps and lanterns must undergo a pressure test of the shell. The purpose is to prove whether the shell can effectively withstand the internal explosion. The test method commonly used in laboratories is hydrostatic pressure testing. The hydrostatic pressure test refers to filling the explosion-proof electrical equipment with liquid, applying a certain pressure to the equipment through the pressure pump and conduit connection, and checking whether the electrical equipment shell can effectively withstand the same pressure of the internal explosion. [0003] Generally, when doing a hydrostatic pressure test, a threaded connector is used to connect the device to be tested and the test equipment. When the device under test is connected to the test equipment, it i...
