Detailed Description

The present application is described in further detail below in conjunction with figures 1-2.

The embodiment of the application discloses an ultrasonic flowmeter energy meter 2 convenient to install. Referring to fig. 1, an energy meter 2 is mounted on a mounting tube 1, the mounting tube 1 is used for being connected with a pipeline during measurement, and the connection mode of the mounting tube 1 and the pipeline is not an important point of the application and is not repeated here.

Referring to fig. 1 and 2, a connection pipe 3 is fixed to the energy meter 2, and an abutment block 5 is fixed to an end of the connection pipe 3 remote from the energy meter 2. An extension pipe 4 is fixed on the outer wall of the installation pipe 1, a connecting block 6 is fixed at one end of the extension pipe 4 away from the installation pipe 1, and an abutting block 5 abuts against the connecting block 6 when the energy meter 2 is installed. The connecting tube 3 is also connected with a connecting tube 7 in a sliding manner on the outer wall of the connecting tube 3, the connecting tube 7 is of a cylindrical structure, the connecting tube 3 penetrates through the upper end face of the connecting tube 7 in a sliding manner, and one end of the connecting tube 7, facing the mounting tube 1, is of an internal hollow structure. The outer diameter of the abutment block 5 is smaller than the inner diameter of the connecting cylinder 7, so that the abutment block 5 can be accommodated in the inner cavity of the connecting cylinder 7. The connecting cylinder 7 can be screwed onto the outer wall of the connecting block 6, so that the rotating connecting cylinder 7 can drive the abutting block 5 to abut against the connecting block 6, thereby connecting the abutting block 5 and the connecting block 6 together. A sealing ring 13 may be provided between the abutment block 5 and the connection block 6, thereby improving the tightness when the abutment block 5 and the connection block 6 are connected together.

Referring to fig. 1 and 2, an adjusting ring 9 is screwed on the outer wall of the extension pipe 4, and the screw thread of the adjusting ring 9 is reversed to the screw thread of the connecting cylinder 7. Threaded holes are formed in the outer wall of the adjusting ring 9, and a limit rod 8 is connected to the outer wall of the adjusting ring 9 in a threaded manner. The outer wall of the connecting cylinder 7 is provided with a long groove 10, and the long groove 10 extends along the axis direction parallel to the connecting cylinder 7. After the connecting cylinder 7 is in threaded connection with the connecting block 6 to enable the abutting block 5 to abut against the connecting block 6, the adjusting ring 9 is rotated to enable the threaded hole in the adjusting ring 9 to be opposite to the long groove 10, the limiting rod 8 penetrates through the long groove 10 to be in threaded connection with the adjusting ring 9, and the width of the long groove 10 and the limiting rod 8 are matched with each other to enable the limiting rod 8 to abut against the inner wall of the long groove 10. The locating piece 11 for locating the connecting cylinder 7 is also arranged on the limiting rod 8, and the connecting cylinder 7 is not easy to reversely rotate under the limiting effect of the limiting rod 8.

The locating piece 11 includes the holding ring of threaded connection on gag lever post 8, rotates the holding ring and can make the one end of holding ring support tightly on connecting cylinder 7 to improve the location effect to connecting cylinder 7. In order to improve the positioning effect on the connecting cylinder 7, two limiting rods 8 are symmetrically arranged on the outer wall of the adjusting ring 9, and the long grooves 10 are in one-to-one correspondence with the limiting rods 8. Further, the outer wall of the connecting cylinder 7 is provided with a limit groove 12, the positioning block can be abutted in the limit groove 12, and one end of the positioning ring abutted in the limit groove 12 is of a coarse structure, such as a stripe structure, a bump structure and the like, so that the positioning effect of the positioning ring on the connecting cylinder 7 is better. When the connecting cylinder 7 tends to rotate, the adjusting ring 9 and the connecting cylinder 7 are reversely threaded, and the limiting rod 8 connects the connecting cylinder 7 and the adjusting ring 9 together, so that the possibility of rotating the connecting cylinder 7 is limited, and the stability of connection is improved.
