Description

Technical Field

[0001] The invention relates to the field of screwdriver tools, and more specifically, to a method for disassembling and assembling an electric energy meter using a dual-purpose metering and maintenance screwdriver. Background Art

[0002] At present, the intelligent fee-controlled energy meter consists of two parts: the energy meter body and the plug-in meter reading module. In daily operation and maintenance, the operation and maintenance personnel need to frequently replace the faulty meter reading module. The meter reading module is embedded in the groove in the energy meter, covered by a cover plate, and screwed. When the energy meter leaves the factory, the manufacturer will add an anti-theft buckle to the screw. The buckle is similar in shape to a bottle cap. The buckle is pressed to lock the card slot to achieve the purpose of anti-theft. During the operation and maintenance process, the operation and maintenance personnel need to remove the buckle first, then unscrew the fixing screws and replace the module. However, there is currently no effective tool or method to remove the buckle. The operation and maintenance personnel can only perform different degrees of violent damage to the buckle, such as using a screwdriver to pry it out and using an electric drill to dig a hole. Although the buckle can be removed, violent damage can easily cause damage to the fixing screws installed behind the buckle and damage to the energy meter casing. In severe cases, the energy meter needs to be replaced, which increases unnecessary workload. Summary of the invention

[0003] In order to overcome the defect of the prior art that there is no effective tool to remove the anti-theft buckle on the electric energy meter, the present invention provides an electric energy meter disassembly and assembly method using a dual-purpose metering and maintenance screwdriver.

[0004] In order to solve the above technical problems, the technical solution of the present invention is as follows:

[0005] A dual-purpose metering and maintenance screwdriver comprises a screwdriver body consisting of a screwdriver rod and a handle, and a sleeve rod, wherein the sleeve rod is movably sleeved on the outer periphery of the screwdriver rod, and both sides of one end of the sleeve rod are wedge-shaped surfaces inclined inwardly; one end of the sleeve rod is arranged on the outer periphery of the top end of the screwdriver rod.

[0006] In the method for disassembling and assembling an electric energy meter, a screwdriver is used to rotate on the buckle surface, so that the screwdriver head passes through the buckle surface and pries up the buckle under the action of rotational friction. The sleeve rod added by the technical solution is used to support the buckle surface when the screwdriver rod is prying up the buckle to prevent the screwdriver rod from slipping, and after the buckle is pried up, it is used to use the wedge structure set at its end as a flat-blade screwdriver head to unscrew the screw under the buckle. During use, first align the screwdriver body with the buckle surface and place it. While rotating the handle, hold the sleeve rod steady and fix one end of it on the buckle surface to prevent the screwdriver from slipping. The buckle penetrates into the center of the buckle under the rotation of the screwdriver rod, thereby prying up the buckle and completing the disassembly of the buckle. Then the buckle is removed from the screwdriver rod, and the wedge structure set at one end of the sleeve rod is used to unscrew the fixing screw set in the buckle, thereby achieving the function of a dual-use screwdriver.

[0007] Preferably, a self-tapping screw thread is provided on the top of the screwdriver rod, and its thread design enables the screwdriver rod to rotate on the buckle surface and penetrate into the center of the buckle as the self-tapping thread penetrates into the buckle, thereby prying up the buckle and completing the removal of the buckle.

[0008] Preferably, a U-shaped slot is provided at one end of the sleeve rod to facilitate observation of the use status of the screwdriver rod.

[0009] Preferably, the screwdriver further comprises a spring, which is sleeved on the screwdriver rod, and one end of the spring is connected to one end of the handle, and the other end of the spring is connected to the other end of the sleeve rod. When the screwdriver is not in operation, the top of the sleeve rod is flush with the top of the screwdriver rod under the action of the spring; when the screwdriver is in use, the sleeve rod presses against the buckle surface, and the screwdriver rod is screwed into the buckle surface. At this time, the spring exerts an elastic force on the sleeve rod to keep it fixed on the buckle surface.

[0010] Preferably, a protrusion structure is provided outwardly on one side of the screwdriver rod, and an L-shaped slot is provided on the sleeve rod at a position matching the protrusion structure, wherein the long side of the L-shaped slot is provided along the direction of the screwdriver rod. Since the operation and maintenance personnel may need to use the screwdriver of the present technical solution to pry up the buckle at a certain angle during operation, and the sleeve rod sleeved on the screwdriver rod will affect the operation of the screwdriver rod, the sleeve rod can be pulled along its L-shaped slot, and the protrusion structure provided on one side of the screwdriver rod is moved to the corner position along the long side direction of the L-shaped slot, at which time the screwdriver rod is exposed, thereby preventing the sleeve rod from affecting the operation of the screwdriver rod.

[0011] Preferably, the surface of the handle is covered with an insulating silicone layer.

[0012] Preferably, the outer side of the handle is provided with anti-slip textures.

[0013] Preferably, the surface of the sleeve rod is covered with an insulating silicone layer.

[0014] Compared with the prior art, the beneficial effect of the technical solution of the present invention is: by combining a screwdriver consisting of a screwdriver rod and a sleeve rod, the screwdriver rod is used to screw into the buckle and pry it up to achieve the removal of the buckle, and the sleeve rod is used to unscrew the screws set behind the anti-theft buckle, thereby realizing the dual-purpose function of the screwdriver.

[0020] The drawings are for illustrative purposes only and should not be construed as limiting the present patent;

[0021] In order to better illustrate the present embodiment, some parts in the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product;

[0022] It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0023] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0024] Example 1

[0025] like Figure 1 The figure shows a schematic diagram of the structure of a dual-purpose metering and maintenance screwdriver of this embodiment.

[0026] The present embodiment proposes a dual-purpose metering and maintenance screwdriver, comprising a screwdriver body consisting of a screwdriver rod 1 and a handle 2, and a sleeve rod 3, wherein the sleeve rod 3 is movably sleeved on the outer periphery of the screwdriver rod 1, and both sides of one end of the sleeve rod 3 are wedge-shaped surfaces inclined inwardly; one end of the sleeve rod 3 is arranged on the outer periphery of the top end of the screwdriver rod 1.

[0027] In this embodiment, a self-tapping screw thread 11 is provided on the top of the screwdriver rod 1 .

[0028] In this embodiment, a U-shaped groove is formed at one end of the sleeve rod 3 , and the surface of the sleeve rod 3 is covered with an insulating silicone layer.

[0029] In this embodiment, the surface of the handle 2 is covered with an insulating silicone layer, and the outer side of the handle 2 is provided with anti-slip textures.

[0030] In the specific implementation process, the screwdriver rod 1 is first aligned with the buckle surface and placed. While rotating the handle 2, the sleeve rod 3 is held steady and its top is stabilized on the buckle surface. The screwdriver rod 1 penetrates into the buckle through the self-tapping screw thread 11 set on its top. The buckle is pried up under the rotation of the screwdriver rod 1, and the buckle is disassembled. Then, the buckle is rotated against the thread 11 on the top of the screwdriver rod 1 to remove the buckle. After the buckle is disassembled, the sleeve rod 3 is held steady and its top is aligned and fixed to the slot above the fixing screw. The fixing screw set behind the buckle can be unscrewed by rotating the sleeve rod 3, thereby achieving the function of a dual-purpose screwdriver.

[0031] The sleeve rod 3 in this embodiment is supported on the buckle surface to stabilize the screwdriver body and prevent the screwdriver body from slipping during use, which may damage the electric energy meter housing. The self-tapping screw thread 11 designed on the top of the screwdriver rod 1 enables the screwdriver rod 1 to penetrate into the buckle along its self-tapping screw thread 11 when rotating on the buckle surface. At the same time, since the buckle is screwed along the thread on the top of the screwdriver rod 1, it is easy to remove the buckle after it is pried up and popped out. After the buckle is disassembled, the wedge structure set on the top of the sleeve rod 3 can be directly used to disassemble the fixing screw, realizing the dual-purpose function of the screwdriver.

[0032] Example 2

[0033] like Figure 2 The figure shows a schematic diagram of the structure of a dual-purpose metering and maintenance screwdriver of this embodiment.

[0034] The present embodiment proposes a dual-purpose metering and maintenance screwdriver, comprising a screwdriver body consisting of a screwdriver rod 1 and a handle 2, and a sleeve rod 3, wherein the sleeve rod 3 is sleeved on the outer periphery of the screwdriver rod 1, and both sides of one end of the sleeve rod 3 are wedge-shaped surfaces inclined inwardly; one end of the sleeve rod 3 is arranged on the outer periphery of the top end of the screwdriver rod 1.

[0035] In this embodiment, a self-tapping screw thread 11 is provided on the top of the screwdriver rod 1 .

[0036] In this embodiment, a U-shaped groove is formed at one end of the sleeve rod 3 , and the surface of the sleeve rod 3 is covered with an insulating silicone layer.

[0037] In this embodiment, the screwdriver further includes a spring 4, which is sleeved on the screwdriver rod 1, and one end of the spring 4 is connected to one end of the handle 2, and the other end of the spring 4 is connected to the other end of the sleeve rod 3. Under normal conditions, the top of the sleeve rod 3 is flush with the top of the screwdriver rod 1 under the action of the spring 4; when the screwdriver is removing the buckle, the sleeve rod 3 is stabilized on the buckle surface, and the screwdriver rod 1 is screwed into the buckle. At this time, the spring 4 has an elastic force on the sleeve rod 3, so that it remains fixed on the buckle surface, preventing the screwdriver rod 1 from slipping when rotating.

[0038] In this embodiment, a U-shaped groove is formed at one end of the sleeve rod 3 , and the surface of the sleeve rod 3 is covered with an insulating silicone layer.

[0039] In this embodiment, the surface of the handle 2 is covered with an insulating silicone layer, and the outer side of the handle 2 is provided with anti-slip textures.

[0040] In the specific implementation process, the screwdriver rod 1 is first aligned with the buckle surface and placed. At this time, the sleeve rod 3 is stabilized on the buckle surface under the action of the spring 4, and then the handle 2 is rotated. At this time, the screwdriver rod 1 is screwed into the buckle along its self-tapping screw thread 11, and while the screwdriver rod 1 is screwed into the buckle, the U-shaped sleeve rod 3 is kept fixed on the buckle surface under the action of the spring 4. The buckle is pried up and popped out under the rotation of the screwdriver rod 1. At this time, since the buckle is screwed along the thread 11 at the top of the screwdriver rod 1, the buckle can be directly taken out, and then the buckle can be rotated against the direction of the self-tapping screw thread 11 to complete the removal of the buckle.

[0041] like Figure 3 The figure shows a schematic diagram of the buckle disassembly state of the dual-purpose metering and maintenance screwdriver of this embodiment.

[0042] After the buckle is removed, the sleeve 3 is restored to its top flush with the top of the screwdriver rod 1 under the elastic action of the spring 4, and can be used to remove the fixing screw. Specifically, the wedge-shaped structure set on the top of the sleeve 3 is aligned with the slot on the upper surface of the fixing screw and clamped, and then the handle 2 is rotated to drive the sleeve 3 to rotate to remove the fixing screw.

[0043] In this embodiment, the flexibility of use of the dual-purpose metering and maintenance screwdriver of this embodiment is enhanced by adding a spring 4, and the maintenance personnel can operate it with one hand during use, without the need to support or remove the U-shaped head cover rod 3 mounted on the outer periphery of the screwdriver rod 1.

[0044] Example 3

[0045] A dual-purpose metering and maintenance screwdriver proposed in this embodiment is based on the dual-purpose metering and maintenance screwdriver proposed in Example 2, in which a protrusion structure 12 is added outwardly on one side of the screwdriver rod 1, and an L-shaped slot 31 is opened on the sleeve rod 3 at a position matching with the protrusion structure 12, wherein the long side of the L-shaped slot 31 is arranged along the direction of the screwdriver rod 1.

[0046] like Figure 4 , which is a schematic diagram of the structure of the dual-purpose metering and maintenance screwdriver of this embodiment.

[0047] Since the maintenance personnel may need to use the screwdriver rod 1 to remove the buckle at a certain angle during the operation, the sleeve rod 3 sleeved on the outer periphery of the screwdriver rod 1 will affect the operation of the screwdriver rod 1. For example, the operator needs to operate from a low position to the electric energy meter installed at a higher position, and at this time the operator can only remove the buckle at a certain angle.

[0048] like Figure 5 The figure shows the working state of the dual-purpose metering and maintenance screwdriver of this embodiment.

[0049] The screwdriver bar 1 is then rotated to engage with the protrusion 12 on one side of the screwdriver bar 1 and the protrusion 12 is then pulled out of the way so that the screwdriver bar 1 is not engaged.

[0050] The same or similar reference numerals correspond to the same or similar components;
