Technical Field

[0001] The utility model relates to the technical field of vacuum pump pipeline connection, in particular to a vacuum pump pipeline connection mechanism. Background Art

[0002] A vacuum pump refers to a device or equipment that uses mechanical, physical, chemical, or physical-chemical methods to evacuate the container to be pumped to obtain a vacuum. Generally speaking, a vacuum pump is a device that improves, generates, and maintains a vacuum in a closed space by various methods; when a permanent magnet variable frequency two-stage vacuum pump is in use, pipeline connection is often required, so a corresponding connection mechanism will be used.

[0003] However, for the pipeline connection mechanisms on the current market, the overall connection mostly uses flange plates and is then fixed with multiple screws. In the case of long-term use, it is very easy for the screws to become loose, and then leakage occurs. Therefore, a vacuum pump pipeline connection mechanism is needed to solve the above problems. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is: in order to overcome the problems existing above, a vacuum pump pipeline connection mechanism is provided, which solves the problem that for the pipeline connection mechanisms on the current market, the overall connection mostly uses flange plates and is then fixed with multiple screws. In the case of long-term use, it is very easy for the screws to become loose, and then leakage occurs.

[0005] The utility model solves its technical problem by adopting the following technical solutions:

[0006] A vacuum pump pipeline connection mechanism includes a connection housing. Plug heads are threadedly installed at both ends of the connection housing. Two groups of plug heads are respectively connected to a first pipeline and a second pipeline. Baffles are installed at the ends of the first pipeline and the second pipeline. A connection structure is arranged on the connection housing, and a fastening mechanism is arranged on the connection structure.

[0007] Preferably, the connection structure includes an adjustment screw rod rotatably connected to the top of the connection housing. A turntable is installed at one end of the adjustment screw rod. Two groups of moving brackets are threadedly connected to the surface of the adjustment screw rod.

[0008] Preferably, two groups of fixing brackets are symmetrically installed at the top of the connection housing. The adjustment screw rod is rotatably connected to the two groups of fixing brackets. One end of the adjustment screw rod penetrates through one of the fixing brackets and extends to the outside of the fixing bracket. The turntable is installed at the end of the extended section.

[0009] Preferably, the fastening mechanism includes locking screws threadedly connected in two sets of moving frames. A first clamping ring is connected to the bottom end of each locking screw. Two telescopic rods are symmetrically connected inside the connection housing. A second clamping ring is installed at the top end of each telescopic rod. A spring is installed on the surface of each telescopic rod.

[0010] Preferably, a swivel base is provided at the bottom end of each of the two locking screws, and the locking screw is rotationally connected to the top of the first clamping ring through the swivel base.

[0011] Preferably, an end plate is installed at the bottom end of each telescopic rod. One end of the spring is installed at the bottom of the connection housing, and the other end is installed on the surface of the end plate.

[0012] The advantages and positive effects of the present utility model are:

[0013] 1. For a vacuum pump pipeline connection mechanism proposed in this application, when connecting the first pipeline and the second pipeline, first insert the first pipeline and the second pipeline into the connection housing. Then rotate the locking screw to drive the first clamping ring to descend to a height lower than the baffle. Then rotate the adjusting screw to drive the two first clamping rings to approach each other. Under the action of the first clamping ring, drive the first pipeline and the second pipeline to be firmly connected. Continue to rotate the locking screw so that the two first clamping rings firmly clamp the first pipeline and the second pipeline. At the same time, the spring can be used to make the second clamping ring further ensure the stability of the connection between the first pipeline and the second pipeline. Finally, threadedly install the two plugs at both ends of the connection housing, effectively avoiding the problem of loosening, and at the same time facilitating installation and disassembly.
