Abstract
Description
Technical Field
[0001] This utility model belongs to the field of switch technology, specifically an exposure handbrake. Background Technology
[0002] An X-ray machine is a device used to produce X-rays. An X-ray machine needs to be equipped with an exposure control lever to operate the exposure. Since X-rays are radiant, the operator presses the button on the exposure control lever to make the X-ray machine perform the exposure operation, thus avoiding close contact between the operator and the X-ray.
[0003] Most existing exposure switches use a single button to control two settings; pressing the button to different positions controls the activation of different settings. When the operator presses the exposure switch button, the corresponding command is transmitted to the X-ray machine, controlling it to perform the appropriate operation.
[0004] When the button is pressed to trigger the first setting, the exposure switch issues an exposure preparation command. Pressing the button again to trigger the second setting triggers an exposure command, activating the exposure circuit and allowing the X-ray machine to complete the exposure process. However, the existing exposure handbrake, which triggers two settings with a single button, provides unclear tactile feedback to the operator regarding whether the first and second settings have been activated. This can lead to operators being unable to definitively determine whether a specific setting has been activated, causing inconvenience in actual use. Utility Model Content
[0005] To address the problems mentioned above, this utility model provides an exposure handbrake. When the first position is triggered, the operator's hand can clearly feel contact with the second button. When the operator's hand contacts the second button, it is clear that the first position has been triggered. When the first button is pressed to the bottom, it is clear that the second position has been triggered. This provides clear feedback to the operator when triggering the first and second positions in actual use, making it convenient to operate in actual use.
[0006] This utility model provides an exposure handbrake, including a housing, a cover connected to the top of the housing, a switch frame inside the housing, a micro switch body connected to the switch frame, a first spring and a second spring on the micro switch body, a pressing rod above the switch frame, a first button connected to the top of the pressing rod, a second button extending through the top of the cover and sleeved outside the first button, and a triggering component for pressing down the first and second springs connected to the pressing rod.
[0007] Furthermore, the trigger assembly includes a trigger rod connected to the pressing rod, a guide hole for the trigger rod to pass through at the top of the switch frame, and a first inclined surface for pressing down the first spring and a second inclined surface for pressing down the second spring at the lower end of the trigger rod.

The trigger rod has a reserved hole, and a magnet is slidably inserted into the reserved hole. The switch frame has a first magnet block and a third magnet block arranged in sequence along the vertical direction. A second magnet block is provided on the side of the switch frame away from the first magnet block, positioned between the first magnet block and the second magnet block.
[0009] Furthermore, the magnetic pillars exert repulsive forces on the first, second, and third magnetic blocks, respectively.
[0010] Furthermore, the magnetic pillars exert attractive forces on the first, second, and third magnetic blocks, respectively.
[0011] Furthermore, a guide block is connected to the side wall of the pressing rod, and the guide plate is provided with a second guide groove for the guide block to slide into.
[0012] Furthermore, a first elastic element is provided between the pressing rod and the switch frame, and a second elastic element is provided between the second button and the switch frame.

[0031] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0032] The following is in conjunction with the appendix Figure 1 To be continued Figure 9 The present invention will be described in detail with specific embodiments.
[0033] like Figures 1 to 9 As shown, the present invention provides an exposure handbrake, including a housing 1, a cover 2 connected to the top of the housing 1, the part of the cover 2 inserted into the housing 1 being threadedly connected to the inner wall of the housing 1, and the cover 2 being threadedly connected to the housing 1.
[0034] The housing 1 has a switch frame 3 inside, which is tightly inserted into the inner wall of the housing 1 and fixed inside the housing 1. When the cover 2 is connected to the housing 1, the lower surface of the cover 2 abuts against the upper surface of the switch frame 3.
[0035] The switch frame 3 is hollow inside, and a micro switch body 4 is fixedly installed inside the switch frame 3. A pressing rod 5 is provided on the top of the switch frame 3. A first button 51 is tightly sleeved on the top of the pressing rod 5. A second button 6 is slidably sleeved on the outside of the first button 51. The top of the pressing rod 5 and the first button 51 protrude through the top of the second button 6. The top of the second button 6 protrudes through the cover 2 and is slidably inserted into the cover 2.
[0036] A first elastic element 52 is provided between the pressing rod 5 and the switch frame 3. The first elastic element 52 supports the pressing rod 5. The first elastic element 52 can be a spring or an elastic sheet. In this embodiment, the first elastic element 52 is a spring. A second elastic element 61 is provided between the second button 6 and the switch frame 3. The second elastic element 61 supports the second button 6. The second elastic element 61 can be a spring or an elastic sheet. In this embodiment, the second elastic element 61 is a spring.
[0037] The push rod 5 is connected to the trigger component 7. The micro switch body 4 is provided with a first spring 41 and a second spring 42. The trigger component 7 is used to contact the first spring 41 and the second spring 42 to trigger the first and second positions of the exposure switch.
[0038] When the operator presses the first button 51, the first button 51 moves downward relative to the second button 6, the first elastic element 52 is compressed, and the pressing rod 5 drives the trigger component 7 to move downward. When the top of the first button 51 is flush with the top of the second button 6, the trigger component 7 presses down the first spring 41 to trigger the first exposure start position. At this time, the operator can clearly feel the contact between the second button 6 and the first button 51 and the second button 6. Then, the operator continues to press the first button 51 and the second button 6, and the first button 51 and the second button 6 move downward synchronously until they are pressed to the bottom. The trigger component 7 moves downward synchronously with the first button 51 and the second button 6. When the first button 51 is pressed to the bottom, the trigger component 7 presses down the second spring 42 to trigger the second exposure switch position. When the operator releases the first button 51, the first button 51 and the second button 6 return to their original positions under the action of the first elastic element 52 and the second elastic element 61.
[0039] When the first gear is activated, the operator can clearly feel the second button 6 in contact with their hand. When the operator's hand is in contact with the second button 6, it is clear that the first gear has been activated. When the first button 51 is pressed to the bottom, it is clear that the second gear has been activated. This provides a clear feedback effect when the operator activates the first and second gears in actual use, making it convenient to operate in actual use.
[0040] The trigger assembly 7 includes a trigger rod 71, the top of which is integrally formed with the pressing rod 5. A guide hole 72 is provided at the top of the switch frame 3, and the trigger rod 71 is slidably inserted into the guide hole 72. The upper end of the trigger rod 71 extends out of the guide hole 72, and the lower end of the trigger rod 71 has a first inclined surface 73 and a second inclined surface 74, with different thicknesses. A first spring piece 41 is correspondingly positioned with the first inclined surface 73, and a second spring piece 42 is correspondingly positioned with the second inclined surface 74. When the trigger rod 71 moves downward, the first inclined surface 73 first contacts the first spring piece 41. As the trigger rod 71 continues to move downward, the first inclined surface 73 presses down on the first spring piece 41 to trigger the first exposure start position. At this time, the second inclined surface 74 contacts the second spring piece 42. As the trigger rod 71 continues to move downward, the second inclined surface 74 presses down on the second spring piece 42 to trigger the second exposure switch position.
[0041] A positioning post 31 is fixedly connected to the upper surface of the switch frame 3. The lower end of the first elastic element 52 is inserted into the positioning post 31. The positioning post 31 positions the first elastic element 52, increasing the stability of the first elastic element 52 when supporting the pressing rod 5. A positioning groove 53 is provided on the lower surface of the pressing rod 5. The upper end of the first elastic element 52 is inserted into the positioning groove 53. The positioning groove 53 positions the first elastic element 52, increasing the stability of the first elastic element 52 when supporting the pressing rod 5.
[0042] A pair of guide plates 32 are fixedly connected to the upper surface of the switch frame 3. The positioning post 31 is placed within the space enclosed by the guide plates 32, and the second elastic member 61 is sleeved on the outside of the guide plates 32. When the second button 6 is pressed down, the guide plates 32 are inserted into the interior of the second button 6.
[0043] A first guide groove 321 is provided between a pair of guide plates 32. The first guide groove 321 is positioned above the guide hole 72. The trigger rod 71 is slidably inserted into the first guide groove 321. The first guide groove 321 guides and limits the movement of the trigger rod 71, thereby increasing the stability of the trigger rod 71 during its movement.
[0044] A second guide groove 322 is provided on the side of a pair of guide plates 32 away from the first guide groove 321. A guide block 54 is fixedly connected to the side wall of the pressing rod 5. During the downward movement of the trigger rod 71, the guide block 54 moves into the second guide groove 322 and slides into the second guide groove 322. The guide block 54 slides in the second guide groove 322, which increases the stability of the trigger rod 71 during the movement.
[0045] The first button 51 has a first protrusion 511 at its lower end, and the second button 6 has a second protrusion 62 at its top. The first protrusion 511 is positioned below the second protrusion 62. When the first button 51 returns to its original position, the first protrusion 511 abuts against the second protrusion 62 to prevent the first button 51 from disengaging from the second button 6.
[0046] The second button 6 has a third protrusion 63 at its bottom and a fourth protrusion 21 at the top of the cover 2. The third protrusion 63 is located below the fourth protrusion 21. When the second button 6 returns to its original position, the third protrusion 63 and the fourth protrusion 21 abut against each other to prevent the second button 6 from detaching from the cover 2.
[0047] The trigger rod 71 is provided with a reserved hole 711, which is provided through a pair of side walls of the trigger rod 71. A magnet post 712 is placed in the reserved hole 711, and the magnet post 712 is slidably connected to the reserved hole 711. When the trigger rod 71 is in the initial state, the reserved hole 711 is placed in the first guide groove 321.
[0048] The switch frame 3 is provided with a first magnet block 33, a second magnet block 34 and a third magnet block 35 respectively. The first magnet block 33 and the third magnet block 35 are placed on the same side and the third magnet block 35 is placed below the first magnet block 33. The second magnet block 34 is placed on the side away from the first magnet block 33 and is positioned between the first magnet block 33 and the third magnet block 35.
[0049] As the trigger rod 71 moves downward, the first magnet 33, the second magnet 34, and the third magnet 35 all generate a repulsive force on the end of the magnet post 712. When the trigger rod 71 returns to its original position, the reserved hole 711 is placed in the first guide groove 321.
[0050] As the trigger lever 71 moves downward, under the action of the first magnet 33, the magnet post 712 is positioned within the pre-drilled hole 711 on the side away from the first magnet 33. When the first position is triggered, the pre-drilled hole 711 moves to a position close to the second magnet 34. Under the action of the second magnet 34, the magnet post 712 moves to the side away from the second magnet 34, and the magnet post 712 abuts against the inner wall of the switch frame 3, producing a collision sound to prompt the operator to trigger the first position.
[0051] As the trigger lever 71 continues to move downwards, when the second position is activated, the pre-drilled hole 711 moves to a position close to the third magnet block 35. Under the action of the third magnet block 35, the magnet post 712 moves away from the third magnet block 35, and the magnet post 712 abuts against the inner wall of the switch frame 3, producing a collision sound to prompt the operator to activate the second position. By setting the magnet post 712 to emit a collision sound at the corresponding position, the feedback effect when the operator activates the first and second positions during actual use is improved.
[0052] During the return of the trigger rod 71 to its original position, the reserved hole 711 moves to a position close to the second magnet 34. Under the action of the second magnet 34, the magnet post 712 moves away from the second magnet 34, and the magnet post 712 abuts against the inner wall of the switch frame 3, producing a collision sound again. When the reserved hole 711 moves to a position close to the first magnet 33, under the action of the first magnet 33, the magnet post 712 moves away from the first magnet 33, and the magnet post 712 abuts against the inner wall of the switch frame 3, producing a collision sound. After the trigger rod 71 returns to its original position, the magnet post 712 is placed inside the reserved hole 711.
[0053] In another embodiment of this application, during the downward movement of the trigger rod 71, the first magnet block 33, the second magnet block 34, and the third magnet block 35 all exert an attractive force on the end of the magnet post 712. When the trigger rod 71 returns to its original position, the reserved hole 711 is placed in the first guide groove 321.
[0054] As the trigger lever 71 moves downward, under the action of the first magnet block 33, the magnet post 712 is positioned within the reserved hole 711 on the side closer to the first magnet block 33. When the first position is triggered, the reserved hole 711 moves to a position closer to the second magnet block 34. Under the action of the second magnet block 34, the magnet post 712 moves towards the side closer to the second magnet block 34, and the magnet post 712 abuts against the inner wall of the switch frame 3, producing a collision sound to prompt the operator to trigger the first position.
[0055] As the trigger lever 71 continues to move downwards, when the second position is activated, the pre-drilled hole 711 moves to a position close to the third magnet 35. Under the action of the third magnet 35, the magnet post 712 moves towards the side closest to the third magnet 35. The magnet post 712 abuts against the inner wall of the switch frame 3, producing a collision sound to prompt the operator to activate the second position. By setting the magnet post 712 to emit a collision sound at the corresponding position, the feedback effect when the operator activates the first and second positions during actual use is improved.
[0056] During the return of the trigger rod 71 to its original position, the reserved hole 711 moves to a position close to the second magnet block 34. Under the action of the second magnet block 34, the magnet post 712 moves to the side closer to the second magnet block 34, and the magnet post 712 abuts against the inner wall of the switch frame 3, producing a collision sound again. When the reserved hole 711 moves to a position close to the first magnet block 33, under the action of the first magnet block 33, the magnet post 712 moves to the side closer to the first magnet block 33, and the magnet post 712 abuts against the inner wall of the switch frame 3, producing a collision sound. After the trigger rod 71 returns to its original position, the magnet post 712 is placed inside the reserved hole 711.
[0057] The top of the cover 2 is provided with a pressing groove 22. When the operator presses the second button 6 to trigger the second gear, the operator's finger is placed in the pressing groove 22. The pressing groove 22 makes it easy for the operator to press the second button 6 downward to trigger the second gear.
[0058] The principle of the exposure switch provided by this utility model is as follows: When the operator presses the first button 51, the first button 51 moves downward relative to the second button 6. When the top of the first button 51 is flush with the top of the second button 6, the first inclined surface 73 presses down the first spring 41 to trigger the first exposure position. At this time, the magnet 712 abuts against the inner wall of the switch frame 3 and makes a collision sound. If the first button 51 and the second button 6 are pressed down, the first button 51 and the second button 6 move downward synchronously until they are pressed to the bottom. The second inclined surface 74 presses down the second spring 42 to trigger the second exposure position. At this time, the magnet 712 abuts against the inner wall of the switch frame 3 and makes a collision sound again. The feedback when the operator triggers the first and second positions is relatively obvious during actual use, and it is convenient to operate in actual use.
[0059] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
