Description

[0002] The wall cable trough opening device is a piece of equipment required during the construction of a house. Its function is to open cable troughs on the concrete wall for laying wire pipes. When in use, the wall cable trough opening device usually has a fixed depth, and the depth of the troughing is controlled by the abutment plate on the device. However, after the construction of the concrete wall is completed, there will still be some uneven bumps on its surface. During the troughing process of the wall cable trough opening device, the abutment plate that controls the depth will move accordingly, and it is easy to abut against the uneven bumps and block the advancement of the cable trough opening device. If the device is lifted over the bumps, the depth of the cable trough at that location will be shallower than the depth at other locations, resulting in inconsistency in the depth of the cable trough opening, which will also affect the laying of wire pipes later.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention provides a moving frame and a card block 1. When there is a protrusion on the wall, the card block will abut and squeeze the protrusion, so that the card block and the limit rod move toward the main stop plate, and at the same time, the spring 1 is compressed. Due to the movement of the limit rod, the push rod can be driven to move together through the fixed frame. At the same time, the movement of the push rod will push the inclined surface block, the movable block and the card block 1 to shrink along the inside of the moving frame through the inclined surface squeezing. At this time, the spring 2 is compressed and causes the card block 1 to detach from the card seat, thereby releasing the fixation of the moving frame and the card seat. The limit rod is squeezed by the protrusion, which will drive the main stop plate and the moving frame to move along the sliding rod, so that the spring 3 is compressed. This design can prevent the slotting mechanism from being blocked by the protrusion and stagnating during slotting, thereby ensuring that the device can continue to slot at the same depth when encountering a protrusion.

[0017] By setting the piston rod 2 and the auxiliary abutment plate, the connecting plate and the piston rod 1 can be driven to move together with the movement of the moving frame. Due to the movement of the piston rod 1, the gas inside the air chamber 1 can be passed into the air chamber 2 through the connecting pipe, so that the piston block 1 moves under the air pressure, and at the same time, the tension spring 1 is stretched and the spring 4 is compressed. When the moving frame moves to abut against the pressure sensing element 1, an electromagnetic element 1 is energized at this time, so that the clamping block 2 clamped with the piston block 2 moves upward under the magnetic attraction of the electromagnetic element 1 on the magnetic plate 1. And make the card block two disengage from the piston block two, at this time, under the elastic recovery action of the spring four, push the piston block two to move, and push the gas inside the air chamber two into the air box, so that the piston rod two drives the auxiliary abutment plate to extend, and the tension spring two is stretched, and finally the piston block two will abut against the other card block two, and make the other card block two clamped in the piston block two to fix it, at this time, the auxiliary abutment plate extends out to contact with the wall, and temporarily replaces the main abutment plate on this side, so as to maintain the balance of the casing, and then keep the slotting mechanism to slot at the same depth.

[0018] When the lever is in contact with the movable frame, the spring forces the movable frame and the movable frame to move upward and out of contact with the movable frame, thereby releasing the locking mechanism of the movable frame and the movable frame from moving upward and out of contact with the movable frame.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 11As shown, the present invention provides a device for opening a wire groove on a wall of a building, comprising a housing 1, a groove opening mechanism 2, a handle frame 3 and two depth control mechanisms 4;

[0033] The slotting mechanism 2 is mounted on the housing 1 and can slot the wall, the handle frame 3 is mounted on the housing 1, and two depth control mechanisms 4 are respectively arranged on both sides of the housing 1;

[0034] The depth control mechanism 4 includes a slide bar 41, which is installed inside the two sides of the casing 1. A moving frame 42 is slidably installed on the slide bar 41. A spring 3 417 is provided on the outer sleeve of the slide bar 41. One end of the spring 3 417 is connected to the inclined block 412, and the other end of the spring 3 417 is connected to the inner cavity of the casing 1. A telescopic component 43 is installed on the outer side of the moving frame 42. A main abutment plate 44 is installed below one side of the telescopic component 43. A limit rod 45 is provided on the inner movable sleeve of the main abutment plate 44. One end of the limit rod 45 is connected to the abutment block 46, and the other end of the limit rod 45 is connected to a spring 1 47. The other end of the spring 1 47 is connected to the inner wall of the main abutment plate 44. The limit rod 4 The outer side of the housing 1 is connected to a fixed frame 48 located on the outer side of the main abutment plate 44, the outer side of the fixed frame 48 is sleeved with a push rod 414, the push rod 414 is movably sleeved inside the moving frame 42, the inside of the moving frame 42 is movably sleeved with an inclined block 412, the bottom of the inclined block 412 is connected to a spring 2 411, the bottom end of the spring 2 411 is connected to the bottom of the inner cavity of the moving frame 42, the two sides above the movable block 410 are connected with inclined blocks 412 that can abut against the push rod 414, the outer side of the housing 1 is connected to a holder 49 located above the moving frame 42, the center above the movable block 410 is connected to a block 1 413, and the top of the block 1 413 is movably clamped inside the holder 49.

[0035] The above scheme is adopted: when there is a bump on the wall, the abutment block 46 will abut and squeeze the bump, so that the abutment block 46 and the limit rod 45 move toward the main abutment plate 44, and at the same time, the spring 1 47 is compressed. Due to the movement of the limit rod 45, the push rod 414 can be driven to move together through the fixed frame 48. At the same time, the movement of the push rod 414 will push the inclined block 412, the movable block 410 and the card block 1 413 to shrink along the inside of the moving frame 42 through the inclined surface extrusion. At this time, the spring 2 411 is compressed, and the card block 1 413 is disengaged from the card seat 49, releasing the fixation of the moving frame 42 and the card seat 49. The limit rod 45 is squeezed by the bump, which will drive the main abutment plate 44 and the moving frame 42 to move along the slide rod 41, so that the spring 3 417 is compressed, so that the slotting mechanism 2 will not be blocked by the bump and stagnate during slotting.

[0036] like Figures 7 to 9As shown, it also includes two auxiliary balancing mechanisms 5, which are respectively installed on both sides of the casing 1. The auxiliary balancing mechanism 5 includes a fixed box 51, which is installed on the outside of the casing 1. The upper and lower parts of the fixed box 51 are respectively provided with an air cavity 2 53 and an air cavity 1 52. The air cavity 1 52 is sleeved with a piston rod 1 55. One end of the piston rod 1 55 extends to the outside of 61 and is connected to a connecting plate 56. The connecting plate 56 is connected to the movable frame 42. An air filter element 1 54 is provided on the air port below the fixed box 51. The outer side of the fixed box 51 is connected with a connecting pipe 521 that can connect the air cavity 1 52 and the air cavity 2 53.

[0037] By adopting the above scheme, as the movable frame 42 moves, the connecting plate 56 and the piston rod 1 55 can be driven to move together. Due to the movement of the piston rod 1 55, the gas inside the air cavity 1 52 can be passed into the interior of the air cavity 2 53 through the connecting pipe 521, thereby increasing the air pressure inside the air cavity 2 53.

[0038] like Figures 7 to 9 As shown, a piston block 57 is sleeved inside the air cavity 2 53, one side of the piston block 57 is connected to a tension spring 58, the other end of the tension spring 58 is connected to the inner wall of the air cavity 2 53, the other side of the piston block 57 is connected to a spring 4 510, and the other end of the spring 4 510 is connected to the piston block 2 59.

[0039] By adopting the above scheme: when the air pressure inside the air chamber 2 53 increases, the piston block 1 57 can be moved by the air pressure, and at the same time the tension spring 1 58 is stretched, and the spring 4 510 is compressed. Under the elastic recovery action of the spring 4 510, the piston block 2 59 is pushed to move, so that the gas inside the air chamber 2 53 can be pushed into the air box 515.

[0040] like Figures 7 to 9 As shown, an air box 515 is connected to the outer side of the casing 1, and the air box 515 is connected to the fixed box 51 and can communicate with the air chamber 53. A piston rod 511 is provided inside the air box 515. The bottom end of the piston rod 511 passes through the air box 515 and is connected to an auxiliary plate 513. A tension spring 514 is connected to the top end of the piston rod 511. The other end of the tension spring 514 is connected to the inner wall of the air box 515. An air filter element 512 is provided on the air hole at the lower outer side of the air box 515.

[0041] By adopting the above scheme: when the air pressure inside the air box 515 increases, the piston rod 511 can drive the auxiliary abutment plate 513 to extend, and the tension spring 514 is stretched. When the auxiliary abutment plate 513 is extended to contact the wall, the auxiliary abutment plate 513 can temporarily replace the main abutment plate 44 on this side, thereby keeping the slotting mechanism 2 slotting at the same depth.

[0042] like Figure 3 , Figures 7 to 9As shown, mounting blocks 516 are connected to both sides above the fixed box 51, an electromagnetic element 1 517 is installed above the interior of the mounting block 516, a clamping block 2 518 is movably sleeved inside the mounting block 516, a magnetic plate 1 519 is connected above the clamping block 2 518, a spring 520 is connected to the top of the magnetic plate 1 519, the top of the spring 520 is connected to the inner wall of the mounting block 516, two clamping blocks 2 518 are arranged, the bottom of one clamping block 2 518 is movably clamped in the interior of the piston block 2 59, and the opposing surfaces of the two clamping blocks 2 518 are both arc surfaces.

[0043] The above scheme is adopted: when in use, the movable frame 42 will move to abut against the pressure sensing element 415. At this time, an electromagnetic element 517 is energized, so that the block 518 engaged with the piston block 59 moves upward under the magnetic attraction of the electromagnetic element 517 on the magnetic plate 519, and the block 518 is separated from the piston block 59.

[0044] like Figure 3 , Figures 7 to 9 As shown, the outer side of the housing 1 is connected to a second pressure sensing element 416 that abuts against the moving frame 42 , and the outer side of the housing 1 is connected to a first pressure sensing element 415 .

[0045] The above scheme is adopted: when resetting, the movable frame 42 is reset and abuts against the pressure sensing element 416. At this time, an electromagnetic element 517 is energized, so that the block 518 engaged with the piston block 59 moves upward under the magnetic attraction of the electromagnetic element 517 on the magnetic plate 519, and the block 518 is separated from the piston block 59.

[0046] like Figure 3 , Figures 9 to 11 As shown, the telescopic assembly 43 includes a connecting rod 431, which is connected to the outer side of the main support plate 44. A connecting block 432 that can be movably mounted on the outside of the connecting rod 431 is installed in the movable frame 42. A spring 6 433 is mounted on the outside of the connecting rod 431, one end of the spring 6 433 is connected to the connecting rod 431, and the other end of the spring 6 433 is connected to the connecting block 432.

[0047] Adopting the above scheme: as the slotting mechanism 2 continues to move, the protrusion will continue to squeeze the block 46 and the main plate 44, and push the main plate 44 to drive the spring six 433 to move along the inside of the connecting block 432, so that the main plate 44 and the block 46 shrink upward under the squeezing action of the protrusion, and the spring six 433 is compressed, and finally the block 46 is separated from the contact with the protrusion, so that the main plate 44 can be located above the protrusion, so that the main plate 44 can pass over the protrusion as the housing 1 moves.

[0048] like Figure 3 , Figures 9 to 11As shown, an electromagnetic element 2 434 is installed on one side of the interior of the connecting block 432, and a clamping block 3 435 is movably sleeved inside the connecting block 432, and a magnetic plate 2 436 is connected to one side of the clamping block 3 435, and a spring 7 437 is connected to the other side of the magnetic plate 2 436, and the other end of the spring 7 437 is connected to the inner wall of the connecting block 432, and the other side of the clamping block 3 435 is movably clamped in the interior of the connecting rod 431.

[0049] With the above solution, when the pressure sensing element 1 415 contacts the movable frame 42, the pressure sensing element 1 415 is subjected to pressure, so that the electromagnetic element 2 434 is energized, and the magnetic plate 2 436 drives the clamping block 3 435 to contract inside the connecting block 432, releasing the clamping connection between the clamping block 3 435 and the connecting rod 431, so that the connecting rod 431 can move in the connecting block 432.

[0050] The working principle and use process of the present invention:

[0051] When in use, the slotting mechanism 2 is powered on, and slots can be made on the wall surface through the slotting mechanism 2. At this time, the main abutment plate 44 will abut against the wall surface and move with the progress of the slotting.

[0052] When there is a bump on the wall, the block 46 will abut and squeeze the bump, causing the block 46 and the limit rod 45 to move toward the main stop plate 44, and at the same time, the spring 1 47 is compressed. Due to the movement of the limit rod 45, the push rod 414 can be driven to move together through the fixed frame 48. At the same time, the movement of the push rod 414 will push the inclined block 412, the movable block 410 and the card block 1 413 to shrink along the inside of the moving frame 42 through the inclined surface squeezing. At this time, the spring 2 411 is compressed, and the card block 1 413 is disengaged from the card seat 49, releasing the fixation of the moving frame 42 and the card seat 49. The limit rod 45 is squeezed by the bump, which will drive the main stop plate 44 and the moving frame 42 to move along the slide rod 41, causing the spring 3 417 to be compressed, so that the slotting mechanism 2 will not be blocked by the bump and stagnant when slotting, thereby ensuring that the device can continue to slot at the same depth when encountering a bump.

[0053] As the moving frame 42 moves, the connecting plate 56 and the piston rod 55 can be driven to move together. Due to the movement of the piston rod 55, the gas inside the air chamber 52 can be passed into the inside of the air chamber 53 through the connecting pipe 521, so that the piston block 57 moves under the air pressure, and at the same time, the tension spring 58 is stretched and the spring 4 510 is compressed. When the moving frame 42 moves to abut against the pressure sensing element 415, an electromagnetic element 517 is energized at this time, so that the block 2 518 clamped with the piston block 2 59 moves upward under the magnetic attraction of the electromagnetic element 517 on the magnetic plate 519, and The second clamping block 518 is disengaged from the second piston block 59. At this time, the piston block 59 is pushed to move under the elastic recovery action of the fourth spring 510, and the gas inside the air chamber 53 is pushed into the air box 515, so that the piston rod 511 drives the auxiliary abutment plate 513 to extend, and the tension spring 514 is stretched. Finally, the second piston block 59 will abut against the other second clamping block 518, and the other second clamping block 518 is clamped in the second piston block 59 to fix it. At this time, the auxiliary abutment plate 513 is extended to contact with the wall and temporarily replaces the main abutment plate 44 on this side, so that the slotting mechanism 2 can keep slotting at the same depth.

[0054] The air filter element 2 512 and the air filter element 1 54 can filter the air when the air cavity 1 52 and the air box 515 are filled with compensating gas.

[0055] When the pressure sensing element 1 415 contacts the movable frame 42, the pressure sensing element 1 415 is subjected to pressure, so that the electromagnetic element 2 434 is energized, and the magnetic plate 2 436 drives the clamping block 3 435 to retract toward the inside of the connecting block 432, releasing the clamping connection between the clamping block 3 435 and the connecting rod 431. At this time, the spring 7 437 is compressed. As the slotting mechanism 2 continues to move, the protrusion will continue to squeeze the block 46 and the main plate 44, and push the main plate 44 to drive the spring 6 433 to move along the inside of the connecting block 432, so that the main plate 44 can be pressed. The abutment plate 44 and the abutment block 46 shrink upwards under the squeezing action of the protrusion, and the spring six 433 is compressed, which eventually causes the abutment block 46 to break away from the abutment with the protrusion, so that the main abutment plate 44 can be located above the protrusion, and the main abutment plate 44 can pass over the protrusion as the housing 1 moves, and finally, under the elastic recovery action of the spring three 417, the movable frame 42 and the main abutment plate 44 are reset, and the auxiliary abutment plate 513 shrinks and resets, so that when the device encounters a protrusion during the groove, it can pass over the protrusion without affecting the groove depth.

[0056] When the movable frame 42 is reset, the connecting plate 56 and the piston rod 55 will be reset together. When the movable frame 42 is reset and abuts against the pressure sensing element 416, another electromagnetic element 517 is energized, so that the block 518 engaged with the piston block 59 moves upward under the magnetic attraction of the electromagnetic element 517 on the magnetic plate 519, and the block 518 is separated from the piston block 59. Under the elastic recovery action of the tension spring 58, the piston block 59 and the piston block 57 are reset, so that the original block 518 continues to be engaged in the piston block 59. Under the elastic recovery action of the tension spring 514, the piston rod 511 and the auxiliary plate 513 are reset.
