Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. 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.

Example 1

As shown in fig. 1 and fig. 2, the embodiment of the present invention provides a taking out tool for an ultrasonic flow meter probe, including a shaft rod 1, a nut 2 and a bracket 3, specifically set as follows:

the shaft rod 1 is used for connecting a probe of the ultrasonic flowmeter. Specifically, the setting of axostylus axostyle 1 perpendicular to probe, set up the assembly groove 12 that supplies the probe to put into on the terminal surface that axostylus axostyle 1 connects the probe, wherein, be equipped with the internal thread on the inslot wall of assembly groove 12, and be equipped with the outer silk that the cooperation is connected in assembly groove 12 on the lateral wall of probe, thereby only need earlier on the assembly groove 12 cover of axostylus axostyle 1 on ultrasonic flowmeter's probe, rotatory axostylus axostyle 1 again, just can cup joint the tip of axostylus axostyle 1 on ultrasonic flowmeter's probe through threaded connection. Preferably, the end of the shaft rod 1 far away from the probe is in an external hexagonal shape, and the shaft rod 1 can be rotationally tightened on the probe through an auxiliary tool such as a wrench, so that the operation is convenient. On the pole wall of 1 interlude of axostylus axostyle, there is screw thread 11 along 1 length direction integrated into one piece of axostylus axostyle, connect 2 screw threads of nut on the pole wall of 1 interlude of axostylus axostyle, make lead screw nut mechanism between nut 2 and the axostylus axostyle 1, based on the screw drive who converts rotary motion into rectilinear motion, when axostylus axostyle 1 rotates, nut 2 is on 1's interlude of axostylus axostyle, be linear motion along 1's length direction of axostylus axostyle, the same reason, when nut 2 only rotates.

As described above, the bracket 3 is supported between the probe and the nut 2 for limiting the displacement after the nut 2 is rotated. Specifically, the support 3 includes a support plate 31 disposed above the probe, and a positioning hole 311 is formed in the middle of the support plate 31 for the shaft rod 1 to vertically pass through, so that the shaft rod 1 can only move along the central axis direction of the positioning hole 311. Legs 32 perpendicular to the bottom surface of the support plate 31 are integrally formed on the bottom surface of the support plate 31, wherein the legs 32 are used for supporting on the pipe wall, and a moving space for the probe to ascend is formed between the legs 32 on the two sides of the support plate 31. During specific operation, the support 3 is supported on the pipe wall, the shaft lever 1 vertically penetrates into the support 3, the shaft lever 1 is rotationally tightened on the probe through auxiliary tools such as a wrench, the nut 2 is attached to the upper surface of the support plate 31 at the moment, the nut 2 only needs to be rotated along the direction of downward movement, based on the limitation of the support 3 on the nut 2, the shaft lever 1 can be lifted upwards under the action of screw transmission under the condition that the displacement of the nut 2 is not changed, so that the shaft lever 1 can vertically pull out the probe and the base, and the movable space for the probe to rise is formed between the support legs 32 on the two sides of the support plate 31 to ensure that the probe is completely pulled out, namely, the shaft lever 1 is lifted by rotating the nut 2 without adopting an uneven hard prying method, the probe is taken out by adopting a vertical drawing mode, and the probe, the O-shaped sealing ring and the base, and for some probes with small intervals, the problem that common tools cannot be operated can be solved, and the operation is convenient. Preferably, the leg 32 is provided with a slot 321 for inserting the pipe, so as to stably support the bracket 3 on the outer wall of the pipe.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
