Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, and particularly relates to a prepayment valve bracket mechanism. Background Art

[0002] Generally, there is a close cooperation relationship between factories and waterworks. In order to reduce the problem of malicious arrears of water fees, the waterworks will set prepayment valves on the water supply valves. The prepayment valves generally adopt electromagnetic control. The valve body, loose flange and water pipe of the prepayment valve are generally processed independently and need to be assembled and fixed on the workbench. Since the loose flange is circular, it will roll back and forth during assembly and cannot be positioned, so the installation is relatively difficult. Content of the Utility Model

[0003] To overcome the above defects, the purpose of the utility model is to provide a prepayment valve bracket mechanism, which is provided with a clamping mechanism on the base to temporarily fix the loose flange to prevent it from rolling, so as to achieve the purpose of quickly installing the billing meter head.

[0004] To achieve the above purpose, the utility model provides a prepayment valve bracket mechanism, which is characterized in that it includes a base and a clamping mechanism; the base is provided with a positioning plate, and a positioning pin is inserted on the positioning plate; the clamping mechanism includes a fixing plate, a first clamping plate and a second clamping plate. A spring is clamped between the first clamping plate, the second clamping plate and the fixing plate. A guide rod is sleeved in the middle of the spring, and the fixing plate is provided with a connecting hole, and the two guide rods are respectively slidably connected in the connecting hole.

[0005] Preferably, the base is provided with a support plate, the base is provided with a limiting groove, and both sides of the limiting groove are respectively fixedly connected with a first limiting baffle and a second limiting baffle of the base, and the first limiting baffle and the second limiting baffle have the same height, and are both lower than the height of the support plate.

[0006] Preferably, the lower ends of the first limiting baffle and the second limiting baffle are both fixedly connected with the same guiding seat, and the guiding seat slides in the limiting groove.

[0007] Preferably, the upper ends of the first clamping plate, the second clamping plate and the support plate are all arc-shaped.

[0008] Preferably, the first clamping plate and the second clamping plate are respectively covered with anti-slip rubber pads.

[0009] Preferably, the upper ends of the first clamping plate and the second clamping plate are respectively provided with wedge-shaped chamfers.

[0010] Preferably, the support plate and the limiting groove are arranged oppositely.

[0011] After adopting the above technical solution, the beneficial technical effects achieved by the present utility model are as follows:

[0012] 1. Since a clamping mechanism is provided on the base, the clamping mechanism includes a fixing plate, a first clamping plate and a second clamping plate. The space between the first clamping plate and the second clamping plate is used to place the pipe fittings to be clamped. Under the action of the spring and the guide rod, the pipe fittings to be clamped can be temporarily fixed. Therefore, when installing the charging meter head, the pipe fittings will not roll, and the installation positioning will be relatively accurate. After the installation is completed, it can be directly and forcibly pulled out, so the efficiency is relatively high.

[0013] 2. Since a support plate is provided on the base, and a first limit baffle and a second limit baffle lower than the support plate are installed. A limit groove is provided at the position between the three baffles. A prepaid valve base meter is connected to the middle parts of two pipes to be clamped, and the volume is relatively large. Through the above-mentioned first limit baffle, second limit baffle and limit groove, temporary fixation can be well achieved, and the angle of the prepaid valve base meter can be rotated and adjusted as needed to meet the rapid installation requirements.

[0014] 3. Since anti-slip rubber pads are respectively covered on the first clamping plate and the second clamping plate, the anti-slip rubber pads can increase the friction force. At the same time, one side of the upper ends of the first clamping plate and the second clamping plate is wedge-shaped. When placing the circular pipe fittings to be clamped, the operator only needs to press down forcefully, and the spring tension changes, then the temporary fixation can be achieved.

[0020] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model, and are not used to limit the present utility model.

[0021] See Figures 1 - 2, the present utility model provides a prepayment valve bracket mechanism, which includes a base 1 and a clamping mechanism 2; the base 1 is provided with a positioning plate, and a positioning pin is inserted into the positioning plate; the positioning pin is used for installation positioning to ensure that when the clamping mechanism 2 is in use, it can avoid the prepayment valve base meter in the middle (not shown in the figure) at the same time. In this way, there will be no interference during installation. The clamping mechanism 2 includes a fixing plate 21, a first clamping plate 22 and a second clamping plate 23. A spring 25 is clamped between the first clamping plate 22, the second clamping plate 23 and the fixing plate 21. A guide rod 26 is sleeved in the middle of the spring 25. The fixing plate 21 is provided with connection holes, and the two guide rods 26 are respectively slidably connected in the connection holes. During use, generally, the pipe fitting to be clamped is directly pressed downwards, and the pipe fitting to be clamped is clamped in the limiting groove 12 between the first clamping plate 22, the second clamping plate 23, the first limiting plate and the second limiting plate, while the support plate 11 supports the shell of the prepayment valve base meter. At this time, the pipe fitting to be clamped will not rotate automatically. According to needs, after manually rotating the prepayment valve base meter by a certain angle, other auxiliary accessories can be installed. During actual use, in order to prevent the guide rod 26 from sliding beyond the predetermined stroke, generally, a limiting hole is also provided at its end, and an opening pin (not shown in the figure) is inserted into the limiting hole.

[0022] A support plate 11 is provided on the base 1 of the present utility model, and the base 1 is provided with a limiting groove 12. The two sides of the limiting groove 12 are respectively fixedly connected with a first limiting baffle 13 and a second limiting baffle 14 of the base 1, and the first limiting baffle 13 and the second limiting baffle 14 have the same height, and are both lower than the height of the support plate 11. After placement, the inclination angle is generally about 30°, and the installation effect of this angle is better. There is a certain space between the first limiting baffle 13 and the second limiting baffle 14, and the base 1 at this place is concave to form a limiting groove 12, and the limiting groove 12 is used for placing the pipe fitting connection part, especially for placing the prepayment valve base meter with a volume larger than the pipe fitting to be clamped. After temporary fixation, the other side of the prepayment valve base meter is supported by the top of the support plate 11. At this time, through the gap between the first limiting baffle 13 and the second limiting baffle 14, auxiliary parts such as batteries and control lines can be installed.

[0023] The same guide seat 24 is fixedly connected to the lower ends of the first limiting baffle 13 and the second limiting baffle 14 of the present utility model, and the guide seat 24 slides in the limiting groove 12. The guide seat 24 is used to ensure the consistency of the movement of the first clamping plate 22 and the second clamping plate 23.

[0024] The upper ends of the first limiting baffle 13, the second limiting baffle 14 and the support plate 11 of the present utility model are all arc-shaped. In the present utility model, the materials of the base 1, the support plate 11 and the clamping mechanism 2 are generally preferably hard synthetic plastics, or other light metal materials such as aluminum alloy, etc. In order to reduce scratching of the operator, larger arc angles need to be set during processing.

[0025] The first clamping plate 22 and the second clamping plate 23 of the utility model are respectively covered with anti-slip rubber pads. The anti-slip rubber pads are used to increase the friction force, ensure the stability of clamping, and at the same time can avoid scratching the pipeline and maintain the smoothness.

[0026] The upper ends of the first clamping plate 22 and the second clamping plate 23 of the utility model are respectively provided with wedge-shaped chamfers. The wedge-shaped chamfers can enable the tubular member to be clamped to be directly clamped between the first clamping plate 22, the second clamping plate 23, the first limit baffle 13 and the second limit baffle 14 by the way of pressing down, with higher efficiency.

[0027] The support plate 11 and the limit groove 12 of the utility model are arranged oppositely. Some electronic components need to be installed in the prepayment valve base meter. Generally, the installation opening of the shell faces the limit groove 12, and the space between the first limit baffle 13 and the second limit baffle 14 is an avoidance space to avoid interference with the tools used during installation.
