Among the current rotary joint, when elbow and duct connections, generally adopt flange joint, need use a plurality of bolts during flange joint, the installation is comparatively troublesome, and the bolt is at the easy smooth silk of wrench movement in-process, leads to dismantling not and the insecure problem of installation.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a low mercury catalyst vacuum rotary joint to propose the problem of being not convenient for installation and dismantlement in solving above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a low mercury catalyst vacuum rotary joint, includes the rotary joint body, one side of rotary joint body is fixed with the mounting, the jack has been run through to one side of mounting, the elbow has been cup jointed to the inboard of jack, the slot has been seted up to the outer wall of elbow, the top and the bottom of mounting have all run through and have extended to the inside pull rod of mounting, the one end of pull rod is fixed with the fixed plate, one side of fixed plate is provided with the inserted block, the opposite side of fixed plate is fixed with the spring.

Preferably, the elbow is provided separately from the socket.

Preferably, a pull ring is fixed at the other end of the pull rod.

Preferably, the insert block and the slot are provided with multiple groups, and the multiple groups of insert blocks are matched with the slots.

Preferably, the elbow is made of nodular cast iron.

Compared with the prior art, the beneficial effects of the utility model are that: the low-mercury catalyst vacuum rotary joint is provided with an insert block, a jack, a spring, a pull rod and a slot, when an elbow is installed, a user firstly pulls pull rings on two sides, the pull ring pulls the pull rod to move, so that a fixed plate is pulled by the pull rod to extrude the spring, when the spring is compressed to a certain degree, the user aligns one end of the elbow with the jack and then inserts the elbow into the rotary joint, then the user loosens the pull ring, at the moment, the extrusion force on the spring is released, due to the resilience of the spring, the spring pushes the fixed plate to move, so that the insert block is inserted into the slot, thereby the fixing effect on the elbow is achieved, when the elbow is disassembled, the user pulls the pull ring in the same way, the spring is extruded, so that the insert block is separated from the slot, the elbow can be extracted from the fixed part and the rotary joint, thereby the disassembly purpose is achieved, the risk that the screw is fixed by the bolt easily and the screw is inconvenient to detach and fix is avoided, and the device is simple, convenient and high in practicability.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying 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 work belong to the protection scope of the present invention.

In the present invention, unless otherwise expressly stated or limited, the terms "disposed," "mounted," "connected," "fixed," "sleeved," and the like are to be construed broadly, e.g., as either a fixed connection, a removable connection, or an integral part; can be mechanically or electrically connected; the two elements may be connected directly or indirectly through an intermediate medium, and the two elements may be connected internally or in an interaction relationship, and a person skilled in the art can understand the specific meaning of the above terms in the present invention according to specific situations.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a low mercury catalyst vacuum rotary joint, including rotary joint body 1, mounting 2, elbow 3, spring 4, pull rod 5, pull ring 6, jack 7, fixed plate 8, inserted block 9 and slot 10, one side of rotary joint body 1 is fixed with mounting 2, one side of mounting 2 runs through jack 7, elbow 3 has been cup jointed to jack 7's inboard, slot 10 has been seted up to elbow 3's outer wall, be convenient for with inserted block 9 looks adaptation, thereby reach fixed purpose, top and the bottom of mounting 2 all run through and have the pull rod 5 that extends to mounting 2 inside, the one end of pull rod 5 is fixed with fixed plate 8, one side of fixed plate 8 is provided with inserted block 9, the opposite side of fixed plate 8 is fixed with spring 4.

Referring to fig. 1-3, the elbow 3 is detachably disposed with the insertion hole 7 for easy assembly and disassembly, and the other end of the pull rod 5 is fixed with a pull ring 6 for easy pulling of the pull rod 5.
