Description

Technical Field

[0001] The utility model belongs to the technical field of industrial circulating water treatment equipment, and specifically relates to a self-positioning water meter cover tightening mechanism. Background Art

[0002] A water meter is an instrument for measuring water flow, mostly the cumulative flow of water. Currently, the basic structure of a water meter includes a meter cover, a glass meter cover and a water meter body. When the water meter is produced or used, the meter cover needs to be tightened to ensure the normal operation of the water meter.

[0003] The traditional way of tightening the water meter cover usually requires manual operation, which may lead to inconvenient operation and low efficiency. In the prior art, there is also a tightening mechanism for tightening. First, the water meter body is placed on the workbench (the water meter cover has been pre-tightened on the water meter), and then multiple electrical components are started, such as an electric push rod to drive the fixing plate to fix the water meter, and then the cover is driven by a rotating drum to rotate for tightening.

[0004] However, multiple electrical components are first provided for fixing, which not only increases the investment cost, but also is time-consuming and labor-intensive during maintenance.

[0005] Secondly, when people place the water meter body on the workbench, it may be placed in the wrong position (that is, the positioning is incorrect), resulting in different distances between the two fixing plates of the water meter body. If the meter cover is directly fixed and tightened, it will cause uneven force, which may seriously damage the meter cover.

[0006] To this end, we proposed a self-positioning water meter cover tightening mechanism, which can automatically fix the water meter without adding any electrical components, thereby saving costs. At the same time, it can position the water meter body so that it is always under the rotating drum, so that it is evenly stressed and the damage to the meter cover is reduced. Utility Model Content

[0007] The purpose of the utility model is to provide a self-positioning water meter cover tightening mechanism, which can automatically fix the water meter without adding any electrical components, thereby achieving the effect of cost saving. At the same time, it can position the water meter body so that it is always under the rotating drum, so that it is evenly stressed and the damage to the meter cover is reduced.

[0008] The technical solutions adopted in this utility are as follows:

[0009] A self-positioning water meter cover tightening mechanism, comprising a bottom plate, a bracket is arranged on the bottom plate, a connecting plate is installed on one side of the bracket, a rotating telescopic assembly is arranged on the connecting plate, a first supporting plate is installed at the bottom of the rotating telescopic assembly, and a rotating cylinder and a first wedge plate are arranged at the bottom of the first supporting plate;

[0010] A bearing plate and two symmetrical first slide grooves are provided on the bottom plate, a first moving component is provided inside the first slide groove, a second wedge plate that fits with the inclined surface of the first wedge plate is provided on the first moving component, a second supporting plate is provided on the second wedge plate, a fixed plate is installed on one side of the second supporting plate, a second slide groove is provided on the bearing plate, a second moving component is provided inside the second slide groove, a sliding plate is provided on the second moving component, and a water meter body is provided on the sliding plate.

[0011] Furthermore, the first moving component includes a first fixed shaft arranged inside the first sliding groove, and a first slider and a first spring are sleeved on the first fixed shaft. One side of the first slider is connected to the first spring, and the top of the first slider is connected to the second wedge plate.

[0012] Furthermore, the first sliding block matches the first sliding groove.

[0013] Furthermore, the second moving component includes a second fixed shaft arranged inside the second sliding groove, the second fixed shaft is sleeved with a second slider and a second spring, the second springs are arranged on both sides of the second slider, and the top of the second slider is connected to the sliding plate.

[0014] Furthermore, the second sliding block matches the second sliding groove.

[0015] Furthermore, the rotating telescopic assembly includes a motor arranged on the connecting plate, a mounting plate is installed at the output end of the motor, an electric telescopic rod is arranged on the mounting plate, and the bottom of the electric telescopic rod is connected to the first supporting plate.

[0016] The technical effects achieved by this utility model are:

[0017] 1. First, place the water meter body on the sliding plate (the water meter body here is a combination of the water meter and the meter cover, that is, the meter cover on the water meter is in a pre-tightened state), and then extend the telescopic component by rotating, thereby driving the rotating cylinder on the first support plate to be sleeved on the meter cover of the water meter body. When moving, the inclined surface of the first wedge plate slides and squeezes on the inclined surface of the second wedge plate, so that the second wedge plate drives the first moving component to move, and when the second wedge plate moves, it drives the second support plate to move the fixed plate, thereby fixing the water meter body. The device can automatically fix the water meter without adding any electrical components, thereby achieving the effect of cost saving.

[0018] 2. When the fixed plate moves, the fixed plate with a shorter distance will first contact the water meter body, so that the water meter body drives the second moving component to move, and then completes the positioning when it contacts and fixes with another fixed plate, so that the water meter body is always located at the bottom of the rotating drum, so as to work. The water meter body can be positioned so that it is always under the rotating drum, so that it is evenly stressed and the damage to the meter cover is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0026] like Figure 1-4 As shown, the technical solution adopted by the utility model is specifically as follows: a self-positioning water meter cover tightening mechanism, comprising a bottom plate 1, a bracket 2 is arranged on the bottom plate 1, a connecting plate 3 is installed on one side of the bracket 2, a rotating telescopic assembly is arranged on the connecting plate 3, a first supporting plate 4 is installed at the bottom of the rotating telescopic assembly, and a rotating drum 6 and a first wedge plate 5 are arranged at the bottom of the first supporting plate 4;

[0027] A bearing plate 7 and two symmetrical first chutes 8 are provided on the bottom plate 1, a first moving assembly is provided inside the first chute 8, a second wedge plate 9 which fits with the inclined surface of the first wedge plate 5 is provided on the first moving assembly, a second supporting plate 10 is provided on the second wedge plate 9, a fixing plate 11 is installed on one side of the second supporting plate 10, a second chute 12 is provided on the bearing plate 7, a second moving assembly is provided inside the second chute 12, a sliding plate 13 is provided on the second moving assembly, and a water meter body 14 is provided on the sliding plate 13.

[0028] Its working principle is as follows: first, place the water meter body 14 on the sliding plate 13 (the water meter body 14 here is a combination of a water meter and a meter cover, that is, the meter cover on the water meter is in a pre-tightened state), and then extend the telescopic assembly by rotating, thereby driving the rotating cylinder 6 on the first supporting plate 4 to be sleeved on the meter cover of the water meter body 14. When moving, the inclined surface of the first wedge plate 5 slides and squeezes on the inclined surface of the second wedge plate 9, so that the second wedge plate 9 drives the first moving assembly to move, and when the second wedge plate 9 moves, it drives the second supporting plate 10 to move the fixed plate 11, thereby fixing the water meter body 14. When people place the water meter body 14 on the sliding plate 13, it may be placed in the wrong position, resulting in different distances between the water meter body 14 and the two fixed plates 11. If the fixed meter cover is directly tightened, it will cause uneven force, which will seriously damage the meter cover. When the fixed plate 11 moves, the fixed plate 11 with a short distance will first contact the water meter body 14, so that the water meter body 14 drives the second moving component to move, and then the positioning is completed when it contacts and fixes with another fixed plate 11, so that the water meter body 14 is always located at the bottom of the rotating drum 6, so as to work. The device can automatically fix the water meter without adding any electrical components, achieving the effect of cost saving. At the same time, it can position the water meter body 14 so that it is always under the rotating drum 6, so that it is evenly stressed and the damage to the meter cover is reduced.

[0029] The bottom plate 1, the bracket 2 and the connecting plate 3 are connected in a U shape, which is convenient for people to use.

[0030] At the same time, the rotating drum 6 is detachably connected to the first supporting plate 4, and the connection method here is a snap connection or a bolt connection. The advantage of such a setting is that the installation and replacement of the rotating drum 6 can be facilitated, and different types of water meters can be processed.

[0031] The inner wall of the inner cavity of the rotating drum 6 is provided with anti-skid protrusions, and the anti-skid protrusions can prevent slipping when tightening.

[0032] like Figure 3As shown, the first moving assembly includes a first fixed shaft 15 arranged inside the first slide groove 8, and the first fixed shaft 15 is sleeved with a first slider 16 and a first spring 17, one side of the first slider 16 is connected to the first spring 17, and the top of the first slider 16 is connected to the second wedge plate 9.

[0033] When the second wedge plate 9 moves, the second wedge plate 9 drives the first sliding block 16 to move on the first fixed shaft 15 to press the first spring 17, thereby driving the fixed plate 11 to move.

[0034] The first sliding block 16 matches with the first sliding groove 8 , and matching here means that the first sliding block 16 can move smoothly inside the first sliding groove 8 without getting stuck.

[0035] like Figure 4 As shown, the second moving component includes a second fixed shaft 18 arranged inside the second slide groove 12, and a second slider 19 and a second spring 20 are sleeved on the second fixed shaft 18. Second springs 20 are arranged on both sides of the second slider 19, and the top of the second slider 19 is connected to the sliding plate 13.

[0036] When the fixed plate 11 drives the water meter body 14 to move, the water meter body 14 drives the sliding plate 13 to move the second sliding block 19 on the second fixed shaft 18, thereby performing positioning.

[0037] The second sliding block 19 matches with the second sliding groove 12 , and matching here means that the second sliding block 19 can move smoothly inside the second sliding groove 12 without getting stuck.

[0038] In order to prevent the fixing plate 11 from shaking when being fixed, an anti-skid surface is provided on the fixing plate 11, and the anti-skid surface can prevent the watch cover from sliding when being tightened.

[0039] The rotating telescopic assembly includes a motor 21 arranged on the connecting plate 3 , the output end of the motor 21 is installed with a mounting plate, the mounting plate is provided with an electric telescopic rod 22 , and the bottom of the electric telescopic rod 22 is connected to the first supporting plate 4 .

[0040] The electric telescopic rod 22 drives the first support plate 4 to move the rotating drum 6 downward so as to be sleeved on the watch cover, and the motor 21 drives the rotating drum 6 to rotate so as to be tightened.

[0041] The working principle of the utility model is as follows: firstly, the water meter body 14 is placed on the sliding plate 13 (the water meter body 14 here is a combination of the water meter and the meter cover, that is, the meter cover on the water meter is in a pre-tightened state), and then the telescopic assembly is extended by rotating, thereby driving the rotating cylinder 6 on the first supporting plate 4 to be sleeved on the meter cover of the water meter body 14, and when moving, the inclined surface of the first wedge plate 5 slides and squeezes on the inclined surface of the second wedge plate 9, so that the second wedge plate 9 drives the first moving assembly to move, and when the second wedge plate 9 moves, it drives the second supporting plate 10 to move the fixed plate 11, thereby adjusting the water meter body 14. When people place the water meter body 14 on the sliding plate 13, the water meter body 14 may be placed in the wrong position, resulting in different distances between the two fixed plates 11. If the fixed meter cover is directly tightened, uneven force will be applied, which may seriously damage the meter cover. When the fixed plate 11 moves, the fixed plate 11 with a short distance will first contact the water meter body 14, so that the water meter body 14 drives the second moving component to move, and the positioning is completed when it contacts and fixes with another fixed plate 11, so that the water meter body 14 is always located at the bottom of the rotating drum 6, so as to work. The device can automatically fix the water meter without adding any electrical components, achieving the effect of cost saving. At the same time, it can position the water meter body 14 so that it is always under the rotating drum 6, so that it is evenly stressed and the damage to the meter cover is reduced.

[0042] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
