Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides an embodiment:

in this implementation: the utility model provides a pressure relief device for seat instrument under bridge, includes pressure relief instrument main part 1 and coupling assembling 5, and the both ends of pressure relief instrument main part 1 coaxial coupling have threaded connection portion 2 and plug 3 respectively, and the one end coaxial coupling of threaded connection portion 2 has plug 3, and the hole is worn to establish by having seted up at the middle part of pressure relief instrument main part 1 to wear to be equipped with application of force pole 4 in wearing to establish the hole department.

Further, coupling assembling 5 includes the connector 51 with pressure release instrument main part 1 coaxial coupling, the one end center department of connector 51 has been seted up and has been inserted and establish groove 53, and the terminal surface of connector 51 is inserting the card that establishes groove 53 department fixed mounting and have two sets of symmetries to set up and establish ear piece 52, setting through coupling assembling 5, can be when the in-service use demand, realize inserting with the help of inserting the effect of establishing groove 53 and card and establishing ear piece 52 and establish, thereby it is rotatory to drive the device regulation from another angle, reach the purpose of pressure release equally.

Further, the diameter of the insertion groove 53 is 15mm, and the length and the width of the fastening ear 52 are both 6mm.
