The utility model solves the problem in the prior art that the external measuring end is fixed and can only be fixed in one direction after installation, and cannot be adjusted according to the actual environment, resulting in the measuring device being unable to perform effective measurements in different installation environments. It is understandable that the above solution can also be used to improve adaptability.

[0022] In this embodiment, the measuring device body 101 is a prior art and is used to measure gas concentration. An external measuring end 102 is provided on the measuring device body 101. Through the mounting assembly, the measuring device body 101 can be flexibly adjusted in direction and angle, so that the external measuring end 102 can be adjusted in orientation as needed, making it easier to find the most suitable measurement position and obtain more accurate concentration data. This solves the problem in the prior art that the external measuring end is fixed and can only be fixed in one direction after installation and cannot be adjusted according to the actual environment, resulting in the measuring device being unable to perform effective measurements in different installation environments.

[0023] The fixing plate 103 is detachably connected to the measuring device body 101 and is located on one side of the measuring device body 101. The shaft 104 is fixedly connected to the fixing plate 103 and is located on a side of the fixing plate 103 away from the measuring device body 101. The fixing bracket 105 is sleeved on the outside of the shaft 104 and is rotatably connected to the shaft 104.

The mounting seat 107 is fixedly connected to the support rod 107. 06 is rotatably connected and is located at one end of the support rod 106 away from the fixing frame 105. The limiting member limits the support rod 106. The angle member drives the shaft rod 104 to rotate. The measuring device body 101 is fixed to the fixing plate 103 by bolts. The shaft rod 104 passes through the fixing plate 103 and is fixedly connected to the fixing plate 103. The fixing frame 105 is U-shaped. The shaft rod 104 is connected to the fixing frame 105 through a bearing so that the shaft rod 104 can rotate freely on the fixing frame 105. The mounting seat 107 is circular, one end of the support rod 106 is fixedly connected to the fixing frame 105, and the other end extends into the mounting seat 107 and is connected to the mounting seat 107 through a bearing. The support rod 106 is coaxial with the mounting seat 107. The rotation of the support rod 106 can drive the measuring device body 101 to rotate, thereby adjusting the direction of the measuring device body 101. The limiting member can limit the support rod 106 to lock the direction. The angle member can drive the shaft rod 104 to rotate. The rotation of the shaft 104 causes the fixing plate 103 to rotate accordingly, thereby adjusting the angle of the measuring device body 101. Through the rotation of the support rod 106 and the shaft 104, the measuring device body 101 can be flexibly adjusted in orientation, making it easier to find the most suitable measurement position and obtain more accurate concentration data. This solves the problem in the prior art that the outer measuring end is fixed and can only be fixed in one direction after installation and cannot be adjusted according to the actual environment, resulting in the measuring device being unable to perform effective measurements in different installation environments.

[0024] Secondly, the gear 108 is sleeved on the outside of the support rod 106 and fixedly connected to the support rod 106; the tooth plate 109 is connected to the mounting seat 107 through the elastic member, and the elastic member is installed on the mounting seat 107 and provides elastic support for the tooth plate 109. The mounting seat 107 has a sliding groove, and the tooth plate 109 is slidably installed in the mounting seat 107 through the sliding groove. The tooth plate 109 has teeth matching the gear 108, and the tooth plate 109 and the gear 108 can be meshed. The elastic member can provide elastic support for the tooth plate 109, so that the tooth plate 109 is always subjected to a force toward the gear 108, and the tooth plate 109 is meshed with the gear 108, thereby locking the gear 108 and achieving the limitation of the support rod 106.

[0025] At the same time, the limiting groove 110 is located on the side of the mounting seat 107 close to the tooth plate 109; the protrusion 111 cooperates with the limiting groove 110, and the limiting groove 110 is located in a rectangular groove, which is located in the sliding groove of the mounting seat 107, and the protrusion 111 is located on both sides of the tooth plate 109. Through the cooperation between the protrusion 111 and the limiting groove 110, the tooth plate 109 is limited to prevent the tooth plate 109 from falling off the mounting seat 107.

[0026] In addition, the pull rod 112 is slidably connected to the mounting seat 107 and fixedly connected to the tooth plate 109; the spring 113 is sleeved on the outside of the pull rod 112 and is located between the tooth plate 109 and the mounting seat 107.

There are two brackets 115, which are respectively located at both ends of the worm 116 to provide support for the worm 116. The worm 116 passes through the bracket 115 and is fixedly connected to the inner ring of the bearing. A screwing cap is provided at the end of the worm 116. Twisting the screwing cap with a screwdriver can drive the worm 116 to rotate, and by screwing the worm 116, the worm wheel 114 is rotated, thereby driving the shaft 104 to rotate.

[0028] In this embodiment, the mounting base 107 is installed in a specified position by bolts, and the pull rod 112 is pulled outward to disengage the tooth plate 109 from the gear 108. The support rod 106 is rotated to adjust the direction of the measuring device body 101. Thereafter, the pull rod 112 is released, and under the elastic force of the spring 113, the tooth plate 109 is engaged with the gear 108, so that the support rod 106 can be locked. Then, the worm 116 is turned by a screwdriver. When the worm 116 rotates, the worm wheel 114 drives the shaft 104 to rotate, so that the angle of the measuring device body 101 can be adjusted. The present application can flexibly adjust the orientation of the measuring device body 101, making it easier to find the most suitable measurement position and obtain more accurate concentration data, thereby solving the problem in the prior art that the outer measuring end is fixed and can only be fixed in one direction after installation, and cannot be adjusted according to the actual environment, resulting in the measuring device being unable to perform effective measurement in different installation environments.
