[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0019] In view of the technical problem in the prior art that the screw holes between the gas meter side cover and the shell are not aligned during installation, the present application provides a gas meter side cover installation limiting device that can align the screw holes on the side cover with the screw holes on the gas meter shell.

[0020] Figure 1 Shows the overall structural diagram of the gas meter side cover installation limit device; Figure 2 A schematic diagram showing the state structure of a limit device for installing a side cover of a gas meter is shown; Figure 1 and Figure 2In the figure, a limiting device for installing the side cover of the gas meter is arranged at the output end of the driving member and is used to position the side cover 200. In specific use, the driving member can be a hydraulic cylinder; it includes a connecting plate 100, and four groups of positioning rods 120 are connected to the bottom end of the connecting plate 100. The four groups of positioning rods 120 correspond to the four sides of the side cover 200 and form a matrix structure. The bottom of the positioning rods 120 has a pointed cone end; the connecting plate 100 and the positioning rods 120 can be driven downward by an external force. When the position of the side cover 200 is offset, one group of positioning rods 120 will first contact the side cover 200. As the positioning rods 120 continue to move downward, the conical structure of the positioning rods 120 can push the side cover 200 toward the center of the matrix. The rectangular structure formed by the four groups of positioning rods 120 can limit the side cover 200 and ensure the accuracy of the position of the side cover 200.

[0021] Figure 3 shows a schematic structural diagram of the pressed part 110; Figure 3In the embodiment, a pressing piece 110 is provided at the bottom end of the connecting plate 100. The pressing piece 110 is placed at the center of the matrix structure on the horizontal projection plane. The pressing piece 110 includes, from top to bottom, a sleeve 111 connected to the connecting plate 100, a rod 112 slidably plugged into the other end of the sleeve 111, and a pressure head 113 connected to the other end of the rod 112. A spring 114 is connected between the sleeve 111 and the pressure head 113. The spring 114 is wound around the outside of the rod 112. The lower edge of the pressing piece 110 is lower than the lower edge of the positioning rod 120 under normal conditions. The pressing piece 110 0 is higher than the lower edge of the positioning rod 120 in the working state; in normal state, the lower edge of the pressing piece 110 is lower than the lower edge of the positioning rod 120. When the device moves downward as a whole, the pressing piece 110 contacts the side cover 200 in advance and presses it to prevent the side cover 200 from having a secondary relative movement. As the device continues to move downward, the spring 114 is compressed, which can make the lower edge of the pressing piece 110 higher than the lower edge of the positioning rod 120 in the working state, so as to prevent the pressing piece 110 from interfering with the downward movement of the positioning rod 120; the pressure head 113 is made of rubber ; It can ensure the pressing force on the side cover 200 and avoid damage to the side cover 200; the positioning rod 120 is slidably connected to the connecting plate 100 through the slide groove 101 and the slider 102, the slide groove 101 is opened on the connecting plate 100, and the slider 102 is slidably connected to the slide groove 101; through this structure, the positioning rod 120 can adjust the distance relative to the center of the matrix structure, so as to cope with side covers 200 of different specifications; the bottom end of the connecting plate 100 is rotatably connected to the rotating plate 130, the rotating plate 130 is placed in the center of the matrix, and the bottom of the rotating plate 130 The ends are eccentrically connected to four groups of cranks 140, and the other ends of the four groups of cranks 140 are respectively connected to the four groups of positioning rods 120; the driving plate 130 is driven to rotate, driving one end of the crank 140 to rotate around the center of the matrix, and utilizing the traction of the crank 140 to drive the positioning rod 120 to slide along the track of the slide groove 101, thereby adjusting the positions of the four groups of positioning rods 120 at the same time, which is beneficial for responding to different models of side covers 200; the rotating plate 130 is rotatably connected to the connecting plate 100 through damping; it can enable the rotating plate 130 to maintain the current state after rotation.

[0022] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
