DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] See also Figure 1 A laser marking component 11 is movably arranged on the marking machine body 1, and a clamping base 2 is arranged on the marking machine body 1 below the laser marking component 11. In the process of using the device, the electric meter case can be fixedly clamped by the clamping base 2, and then the laser marking component 11 can be moved by the moving component on the marking machine body 1, so that the electric meter case can be marked by the laser marking component 11.

[0020] The laser marking component 11 interacts with the surface of the material through a high-energy laser beam, and utilizes the high energy density after the laser is focused to cause physical and chemical changes such as ablation, oxidation or discoloration of the material, thereby leaving a permanent mark. It is worth noting that the specific structure of the marking machine body 1 and the laser marking component 11 and the marking method thereof are all prior art, so they are not elaborated in detail in the present invention.

[0021] See also Figure 2-6 A square handle 3 is vertically movably provided on the top of the clamping base 2, and a handle clamping cavity 22 is adapted to the square handle 3 at the top of the clamping base 2. A plurality of connecting rods 32 are fixedly provided on the bottom of the square handle 3, and a plurality of vertical rods 321 are fixedly provided vertically upward on the top of the connecting rod 32.

[0022] The connecting rod cavity 222 is adapted to be opened in the clamping base 2 corresponding to the connecting rod 32. The height of the connecting rod cavity 222 is relatively high, so that when the square handle 3 moves vertically, the connecting rod 32 can also be located in the connecting rod cavity 222 and move vertically, thereby driving the vertical rod 321 and the first pressing piece 322 to move vertically synchronously. In addition, a silicone anti-skid pad is provided on the inner wall of the connecting rod cavity 222, so that when the connecting rod 32 is located at a high position in the connecting rod cavity 222, it will not automatically fall down due to gravity, but requires external force to move downward.

[0023] A plurality of fixed seats 23 are fixedly arranged on the clamping base 2, and a first pressing groove 231 adapted to the first pressing piece 322 is opened on the top of the fixed seat 23, and a vertical rod cavity 232 is vertically opened in the middle of each fixed seat 23, and the two ends of the vertical rod cavity 232 are respectively connected with the first pressing groove 231 and the connecting rod cavity 222. This allows the vertical rod 321 on the connecting rod 32 to pass through the vertical rod cavity 232 and be fixedly connected with the first pressing piece 322 above the first pressing groove 231, so that the vertical movement of the square handle 3 can drive the connecting rod 32, the vertical rod 321 and the first pressing piece 322 to move vertically synchronously.

[0024] The inner wall of the handle clamping cavity 22 is paved with a silicone pad 221. The silicone pad 221 can support the square handle 3 under normal circumstances to prevent the square handle 3 from falling into the handle clamping cavity 22. When the square handle 3 is subjected to external force, it can be pressed into the handle clamping cavity 22. At this time, the silicone pad 221 can enhance the friction force of the square handle 3 in the handle clamping cavity 22, so that the square handle 3 can be stably clamped in the handle clamping cavity 22. The top of the silicone pad 221 is chamfered so that the square handle 3 can be pressed into the handle clamping cavity 22 when subjected to external force.

[0025] When the square handle 3 is located above the handle cavity 22, the silicone pads 221 on both sides can support the square handle 3. This can prevent the square handle 3 from falling into the handle cavity 22 due to its own gravity and the gravity of the connecting rod 32, the vertical rod 321, and the first pressing piece 322. At this time, the square handle 3 is located above the handle cavity 22, and the first pressing piece 322 is also adapted to be located above the first pressing groove 231.

[0026] When the user presses the electric meter case to position it on the clamping base 2, the electric meter case can press the first pressing piece 322, so that the first pressing piece 322 can be pressed into the first pressing groove 231 through the electric meter case. At this time, the square handle 3, the connecting rod 32 and the vertical rod 321 can be driven to move downward synchronously through the first pressing piece 322. At this time, the square handle 3 can move into the handle clamping cavity 22 due to the downward force, and the friction force of the square handle 3 in the handle clamping cavity 22 can be increased through the silicone pads 221 on both sides, so that the square handle 3 can be stably clamped in the handle clamping cavity 22, so that the support rods 31 on the square handle 3 can be driven to move downward synchronously.

[0027] See also Figure 2-3 , 7-12, 20, a clamping seat cavity 21 is opened on the inner wall around the clamping base 2, and the clamping components 5 are fixedly installed in the clamping seat cavity 21.

[0028] There are four groups of clamping assemblies 5. In this embodiment, each group of clamping assemblies 5 is composed of seven fixed clamping seats 51. The fixed clamping seat 51 in the middle is the longest, and five second pressing members 55 are arranged above it. The second pressing members 55 on the fixed clamping seats 51 on both sides decrease in number and length.

[0029] The fixed clamp seat 51 is provided with an air cavity inside, and the communicating port of the air cavity is connected with an elastic bellows 52, and the other end of the elastic bellows 52 is in a closed state. The movable pressure plate seat 53 is fixedly connected to the closed end of the elastic bellows 52, so that when the air cavity is occupied and the volume is reduced, the elastic bellows 52 can be extended due to the gas pressure, thereby driving the movable pressure plate seat 53 to move.

[0030] A plurality of guide crossbars 57 are fixedly arranged on both sides of the fixed clamp seat 51, and both sides of the bottom of the movable pressure plate seat 53 are guided and moved by the guide crossbars 57. The movable pressure plate seat 53 is fixedly arranged with elastic anti-skid pads 532, which can not only improve the pressure setting and positioning effect of the movable pressure plate seat 53 on the electric meter case, but also enable the movable pressure plate seat 53 to adapt to the uneven parts of the electric meter case.

[0031] The top of the fixed clamp seat 51 is provided with a plurality of second pressing grooves 54 downwardly, and a plurality of second pressing members 55 are movably arranged in the second pressing grooves 54. The bottom of the second pressing members 55 are provided with a plurality of guide columns 552 fixed downwardly and vertically, and the guide columns 552 pass through the second pressing grooves 54 and are inserted into the air inlet cavity, and the bottoms of the guide columns 552 are fixedly connected to the top member 551. By setting the top member 551, the movable magnet 40 can be pushed back into the magnet cavity 41 when it moves downward.

[0032] It is worth noting that the plug holes of the second pressing groove 54 corresponding to the guide pillars 552 are all provided with sealing members in the prior art to prevent gas leakage in the air cavity. A damping pad is provided on the inner wall of the sealing member. Through the effect of the damping pad on the guide pillars 552, the second pressing member 55 can be stably located above the second pressing groove 54, and will not fall into the second pressing groove 54 by its own gravity, so that it can only be moved by external force. This is all prior art, so it will not be described in detail.

[0033] The corresponding second pressing pieces 55 in the fixing clamp seat 51 are all equipped with magnetic plates 56 . The magnetic plates 56 are all guided to move by the guide columns 552 , and the magnetic plates 56 in the same fixing clamp seat 51 are all connected by the connecting plates 561 .

[0034] The bottom of the fixing clamp seat 51 is provided with a through cavity 58, which is located below the magnetic plate 56, and an elastic diaphragm 581 is installed on the through cavity 58. The elastic diaphragm 581 can ensure the sealing inside the air cavity.

[0035] A connecting seat 311 is vertically movable in the fixing clamp seat 51, and the top of the connecting seat 311 is connected to the support rod 31, and the top of the support rod 31 extends out of the fixing clamp seat 51 and is connected to the square handle 3. The side of the connecting seat 311 is connected to the magnetic plate 56 through the connecting plate 561, so that the magnetic plates 56 and the square handle 3 in all the fixing clamp seats 51 can be fixedly connected together through the support rod 31 and the connecting seat 311, so that the magnetic plates 56 can move vertically synchronously with the square handle 3. In addition, the holes on the fixing clamp seat 51 corresponding to the insertion of the support rod 31 are also provided with sealing members in the prior art to ensure the sealing effect inside the air cavity.

[0036] See also Figure 13-15 , the magnetic plate 56 is adapted to be provided with a guide cavity 562 corresponding to the guide column 552, and both sides of the guide cavity 562 are provided with a connected lifting cavity 563, and both sides of the guide column 552 are adapted to be provided with a lifting member 553 corresponding to the lifting cavity 563. The adaptation setting between the guide cavity 562 and the guide column 552 can improve the stability of the magnetic plate 56 during the movement process.

[0037] Through the adaptation arrangement between the lifting cavity 563 and the lifting member 553, when the magnetic plate 56 moves upward, the lifting cavity 563 can push the lifting member 553 upward, so that the lifting member 553 can drive the guide column 552, the lifting member 551 and the second pressing member 55 to move upward synchronously. In this way, when the magnetic plate 56 moves upward, the second pressing member 55 can be pushed upward and reset from the second pressing groove 54. And the damping pad can prevent the pushed-out second pressing member 55 from automatically falling due to gravity by the action of the guide column 552.

[0038] See also Fig. 9 , 16 -19, the fixed base 4 is fixedly installed below the fixed clamp seat 51, and a plurality of magnet cavities 41 are opened on the fixed base 4. The magnet cavities 41 are all located below the through cavity 58. Active magnets 40 that are adapted to and attracted to the magnetic plate 56 are arranged in the magnet cavities 41, and the tops of the active magnets 40 are fixedly connected to the elastic diaphragm 581.

[0039] The fixed base 4 is provided with side cavities 42 on both sides of the magnet cavity 41, and a fixed shaft 421 is provided in the side cavities 42. A lever 422 is rotatably provided on the fixed shaft 421. One end of the lever 422 is located at the bottom of the movable magnet 40, and a pressure cavity 401 is adapted to be provided at the bottom of the movable magnet 40 corresponding to the lever 422.

[0040] A locking strip 43 is vertically movably provided at the top of the other end of the lever 422, and a plurality of wedge-shaped clips 431 are fixedly provided at the top of the locking strip 43, and wedge-shaped clip cavities 531 are adapted to be opened at the bottom of both sides of the movable pressure plate seat 53 corresponding to the wedge-shaped clips 431 on the locking strip 43.

[0041] When the movable magnet 40 moves downward, it can press one end of the lever 422 downward through the pressure cavity 401. In this way, the locking strip 43 can be pushed upward through the other end of the lever 422, so that the wedge-shaped clamping piece 431 on the locking strip 43 can be pushed into the wedge-shaped clamping cavity 531 on the movable pressure plate seat 53, so that the movable pressure plate seat 53 can be fixed through the adaption clamping between the wedge-shaped clamping piece 431 and the wedge-shaped clamping cavity 531, so as to improve the clamping effect of the movable pressure plate seat 53 on the meter case.

[0042] It is worth noting that both ends of the lever 422 are not fixedly connected to the pressure chamber 401 and the locking strip 43, but are only located below the pressure chamber 401 and the locking strip 43, so as to drive the locking strip 43 to move through the vertical movement of the pressure chamber 401. And because the moving distance of the locking strip 43 is short, the rotation angle of the end of the lever 422 is sufficient to drive the locking strip 43 to move vertically. And both sides of the side chamber 42 and the locking strip 43 are adapted to be provided with corresponding guides and guide grooves to improve the stability of the locking strip 43 during the vertical movement.

[0043] In this embodiment, the marking process of the electric meter housing can be realized by the laser marking assembly 11 on the marking machine body 1. This is the prior art, so it will not be described in detail.

[0044] When the user is marking the meter case, he only needs to place the meter case in the middle of the clamping base 2 and press the meter case downwards. At this time, the first pressing member 322 can be pressed into the first pressing groove 231 through the meter case, and the second pressing member 55 can be pressed into the second pressing groove 54 at the same time.

[0045] When the first pressing piece 322 moves downward into the first pressing groove 231, the vertical rod 321 and the connecting rod 32 move downward synchronously, thereby driving the square handle 3 to move downward into the handle cavity 22, and driving the supporting rod 31 and the connecting seat 311 to move downward synchronously through the square handle 3.

[0046] At this time, the movement of the connecting seat 311 can drive all the magnetic plates 56 in the fixed clamp seat 51 to move downward synchronously. When the magnetic plates 56 move downward to the bottom, the distance between the magnetic plates 56 and the movable magnets 40 is close, so that the movable magnets 40 can be attracted upward by the magnetic attraction between the magnetic plates 56 and the movable magnets 40. At this time, the movable magnets 40 pass through the through cavity 58 and move upward into the fixed clamp seat 51, and through the setting of the elastic diaphragm 581, the movable magnets 40 cannot enter the air cavity, but squeeze the volume of the air cavity by moving upward.

[0047] When the volume of the air cavity is compressed, the elastic bellows 52 can be extended due to the gas pressure, thereby driving the movable pressure plate seat 53 to move, so that the electric meter case can be pressed by the elastic anti-slip pad 532 on the movable pressure plate seat 53.

[0048] Furthermore, when the electric meter case presses the first pressing member 322 into the first pressing groove 231, the second pressing member 55 at the bottom thereof can also be simultaneously pressed into the second pressing groove 54. When the second pressing member 55 moves downward, it can drive the guide column 552 and the top member 551 to move downward synchronously. When the top member 551 moves downward, it can support the elastic diaphragm 581 on the through cavity 58 to prevent the movable magnet 40 below the through cavity 58 from moving upward through the magnetic attraction force and being attracted to the magnetic plate 56.

[0049] The advantage of this is that by pressing the first pressing piece 322 into the first pressing groove 231, all the magnetic plates 56 can be moved downward, so that all the active magnets 40 are attracted upward by magnetic attraction, thereby squeezing the air cavity and moving the active pressing plate seat 53. However, due to the volume limitation of the electric meter case, it can only press the second pressing piece 55 at the bottom of itself into the second pressing groove 54, so that it can only push the top piece 551 at the bottom downward, so that part of the active magnet 40 can be prevented from moving upward by magnetic attraction and being attracted to the magnetic plate 56 by part of the top piece 551. In this way, the amount of upward movement of the active magnet 40 can be controlled according to the actual volume of the electric meter case, so as to achieve the regulation of the squeezing volume of the air cavity, thereby achieving the regulation of the moving distance of the active pressing plate seat 53. So that the elastic anti-skid pad 532 on the active pressing plate seat 53 can achieve the pressing of the electric meter case without moving too much distance.

[0050] For example, the longest fixed clamp seat 51 in this embodiment is provided with five second pressing members 55, magnetic plates 56 and movable magnets 40, and the five movable magnets 40 can be attracted upward by moving the magnetic plates 56. At this time, if the electric meter case presses two second pressing members 55, the two movable magnets 40 can be pushed downward by the push member 551, and only three movable magnets 40 can squeeze the air cavity. The moving distance of the movable pressing plate seat 53 is longer, so as to realize the pressing of the electric meter case with a smaller volume.

[0051] If the meter case presses three second pressing pieces 55, the three movable magnets 40 can be pushed downward by the top piece 551, and only two movable magnets 40 can squeeze the air cavity. The moving distance of the movable pressing plate seat 53 is short, so as to realize the pressing of a larger meter case.

[0052] Furthermore, when the top member 551 presses the movable magnet 40 downward, one end of the lever 422 can be pressed downward through the pressure cavity 401 at the bottom of the movable magnet 40, thereby driving the other end of the lever 422 to lift up to push the locking strip 43 upward. At this time, since the movable pressure plate seat 53 has moved to the side of the electric meter case and presses the electric meter case, when the locking strip 43 moves upward, the wedge-shaped clamping member 431 at the top can be automatically clamped into the wedge-shaped clamping cavity 531 at the bottom of the movable pressure plate seat 53 to fix the movable pressure plate seat 53, thereby enhancing the pressing effect of the movable pressure plate seat 53 on the electric meter case. In this way, the electric meter case can be firmly limited by the pressing of the movable pressure plate seat 53 on the multiple fixed clamp seats 51, and the marking process of the electric meter case can be realized by the laser marking component 11.

[0053] It is worth noting that since there are more wedge-shaped cavities 531 at the bottom of the movable pressure plate seat 53, there are also multiple wedge-shaped clamps 431 on the top of the locking strip 43, and only the locking strip 43 under the second pressure piece 55 pressed down by the meter case can be lifted up by the lever 422. Therefore, when the movable pressure plate seat 53 is pressed against the meter case, there are always wedge-shaped clamps 431 to fix the movable pressure plate seat 53.

[0054] Furthermore, when the user needs to take out the meter case after marking, he only needs to pull the square handle 3 upward from the handle clamping cavity 22. At this time, the support rod 31, the connecting seat 311 and the magnetic plate 56 can be driven to move upward synchronously through the movement of the square handle 3. In this way, the distance between the magnetic plate 56 and the active magnet 40 can be increased to release the magnetic attraction between the magnetic plate 56 and the active magnet 40, so that the active magnet 40 can fall back into the magnet cavity 41 by its own gravity. At this time, the active magnet 40 no longer squeezes the air cavity, and the elastic bellows 52 can drive the active pressure plate seat 53 to automatically reset by its own elastic force.

[0055] And when the magnetic plate 56 moves upward, it can drive the lifting member 553 to move upward through the lifting cavity 563, so that the lifting member 553 can drive the guide column 552, the top member 551 and the second pressure member 55 to move upward synchronously, thereby realizing the resetting of the second pressure member 55.

[0056] The square handle 3 can also drive the connecting rod 32, the vertical rod 321 and the first pressing piece 322 to move upward synchronously, so that the first pressing piece 322 can be reset and the electric meter case can be lifted upward by the first pressing piece 322. At this time, the user can directly take out the electric meter case.

[0057] After the square handle 3 is moved out of the handle cavity 22, the silicone pad 221 can automatically reset to support the square handle 3 again. The height of the square handle 3 is greater than the height of the handle cavity 22, and the sides of the square handle 3 are provided with anti-slip pads to facilitate the user to take out the square handle 3.

[0058] Furthermore, the second pressing member 55 can be prevented from falling downward by disposing the damping member in the sealing member on the second pressing groove 54. This is a prior art, so no further details will be given.

[0059] It is worth noting that when the first pressing member 322 and the second pressing member 55 move downward synchronously, the movable magnet 40 is first attracted upward by the magnetic plate 56, and the movable pressing plate seat 53 moves first. Then the top member 551 can be released from the movable magnet 40 and pressed downward, and the movable pressing plate seat 53 is locked and fixed by the locking strip 43. Therefore, there is no problem that the movable pressing plate seat 53 cannot be moved to the correct position due to the locking of the locking strip 43.

[0060] In the present invention, the electric meter case can be marked by the laser marking component 11 on the marking machine body 1, and the electric meter cases of different sizes can be clamped by the movable setting of multiple movable pressure plate seats 53 in the clamping base 2, which has high flexibility and is easy to operate, making it convenient for staff to position and mark the electric meter case.

[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
