Description

Technical Field

[0001] The present application relates to the field of gradient amplifiers, and in particular to a quick tightening and loosening mechanism and a cabinet structure of replaceable components of a gradient amplifier. Background Art

[0002] A gradient amplifier is an electronic component used to amplify and process electrical signals. Its basic principle is to increase the gradient or slope of the input signal, thereby enhancing the signal strength for subsequent circuit processing and analysis.

[0003] The replaceable components in the gradient amplifier are electronic components. The replaceable components are usually fixed to the frame of the cabinet by bolts. During on-site repair and maintenance, the bolts need to be removed one by one to remove the replaceable components, which is inefficient. Summary of the Invention

[0004] In order to improve the efficiency of disassembly and assembly of replaceable components of a gradient amplifier, the present application provides a quick tightening and loosening mechanism and a cabinet structure for replaceable components of a gradient amplifier.

[0005] The present application provides a gradient amplifier with a quick release mechanism and cabinet structure for replaceable components, which adopts the following technical solutions:

[0006] The cam surface and the locking concave surface of the locking cam are formed on the locking cam and the locking cam are locked to the locking cam.

[0007] By adopting the above technical solution, each replaceable component corresponds to two sets of quick tensioning mechanisms, one set on the top and the other set on the bottom, to fix the replaceable component. When the replaceable component is placed in the installation space between the fixed beam and the movable beam, it is first pressed against the limit plate of the fixed beam, and then the movable beam is slid to press against the replaceable component, and then the tensioning handle is turned, and the abutment column moves along the surface of the cam until it enters the locking concave surface. At this time, the tensioning plate rotates, so that the tightening part presses against the limit plate of the movable beam, and the fixed beam and the movable beam can fix the replaceable component; that is, in practice, only the tensioning handle needs to be turned to loosen and tighten the movable beam, that is, to fix and loosen the replaceable component, which is convenient for disassembly and assembly.

[0008] Preferably, the tightening member is configured as a tightening bolt, and a plurality of the tightening bolts are provided.

[0009] By adopting the above technical solution, the tightening member is set as a tightening bolt. When the tightening plate rotates toward the moving beam, the tightening bolt gradually presses against the moving beam, thereby achieving the fixation of the movable beam and the fixed beam to the replaceable component.

[0010] Preferably, both the movable crossbeam and the fixed crossbeam are provided with gaskets.

[0011] By adopting the above technical solution and using gaskets, the friction of replaceable components during disassembly and assembly can be reduced, thereby reducing damage to the replaceable components.

[0012] Preferably, both ends of the movable crossbeam are provided with L-shaped sliding blocks, a sliding groove is formed between the L-shaped sliding blocks and the movable crossbeam, and the sliding groove is slidably matched with the frame.

[0013] By adopting the above technical solution, a sliding groove is formed between the L-shaped slider and the movable beam, and the sliding groove and the frame are slidably matched, so that the movable beam can slide on the frame by external force.

[0014] Preferably, the tightening member is configured as a tightening block, and the tightening block slides on the elastic plate. A compression spring is provided in the elastic plate, and the length direction of the compression spring is consistent with the sliding direction of the tightening block. One end of the compression spring is connected to the tightening block, and the other end of the compression spring is connected to the inner wall of the elastic plate. The elastic plate is provided with a locking member for locking the tightening block.

[0015] By adopting the above technical solution, the tensioning handle is rotated until the abutting column enters the locking concave surface of the linkage plate, at which time the movement of the tensioning plate is completed. In the long-term continuous loosening and tightening process, wear and tear are inevitable, resulting in the tensioning plate being unable to fully act on the moving beam; therefore, in the present application, the tensioning block is in an extended state under the action of the compression spring. When the tensioning plate rotates, the tensioning block first contacts the moving beam, and then the tensioning block will slide into the tensioning plate until the rotation stroke of the tensioning plate is completed, and the tensioning block is locked by the locking piece, at which time the tensioning block is pressed against the moving beam; in practice, even if wear occurs, the tensioning block can always be pressed against the moving beam under the action of the compression spring, and after the rotation of the tensioning handle is completed, the locking piece locks the tensioning block.

[0016] Preferably, the abutment column is rotatably connected to the elastic plate.

[0017] By adopting the above technical solution, when the tensioning handle is rotated, the linkage plate will drive the abutment column to move, and friction will be generated between the linkage plate and the abutment column. Long-term tensioning will cause wear on the surface of the abutment column or the linkage plate, affecting the tightening effect of the tensioning plate on the moving beam. By rotating the abutment column, the friction between the linkage plate and the abutment column can be reduced, which in turn helps to reduce the wear between the abutment column and the linkage plate and ensure the tightening effect.

[0018] Preferably, the locking member is configured as a locking tooth, and the locking tooth is slidably arranged in the elastic plate. An auxiliary rack is formed on the side of the pressing block. When the locking tooth slides, the locking tooth engages with the auxiliary rack to lock the pressing block.

[0019] By adopting the above technical solution, when the tensioning handle rotates to drive the tensioning plate to rotate, after the rotation stroke of the tensioning plate is completed, the locking tooth slides and engages with the auxiliary rack to achieve locking of the tensioning block, thereby ensuring the tensioning effect of the tensioning block on the moving beam.

[0020] Preferably, the linkage plate is formed with a plurality of driving teeth on the side of the cam surface, and the driving teeth are distributed along the contour of the cam surface. A driven gear is coaxially fixed to the abutment column, and when the tensioning handle is rotated, the driving teeth on the linkage plate mesh with the driven gear; a linkage gear meshing with the driven gear is rotatably connected in the tensioning plate, and a connecting rod is hinged on the linkage gear, and the hinge point between the connecting rod and the linkage gear is eccentrically arranged with the linkage gear, and a sliding plate is slidingly arranged in the tensioning plate, and the end of the connecting rod away from the linkage gear is hinged to the sliding plate; a sliding groove is provided on the sliding plate, and the lower end of the locking tooth is in the shape of a T-shaped block, and the lower end of the locking tooth is connected to the The sliding groove slides together, and the sliding plate is provided with an abutment spring in the sliding groove, and the abutment spring is located on the side of the locking tooth close to the abutting block, one end of the abutment spring is connected to the inner wall of the sliding groove, and the other end of the abutment spring is connected to the locking tooth, and a baffle is also provided in the tensioning plate, and the baffle is located on the side of the locking tooth away from the abutting block; in the open state, the locking tooth abuts against the baffle, and the abutment spring is in a compressed state at this time; when switching from the open state to the closed state, the sliding plate slides, and the abutment spring gradually extends. When the abutment spring is completely released, the sliding plate drives the locking tooth to slide synchronously toward the abutting block until the locking tooth and the auxiliary rack are engaged.

[0021] When the cam is in the closed position, the locking plate is moved in a direction away from the locking gear, and the locking tooth and the sliding groove are relatively moved, and the locking tooth abuts against the baffle under the action of the abutment spring. When the sliding plate slides until the abutment spring is fully released, the sliding plate can drive the locking tooth to slide in the direction of the abutment block until the locking tooth meshes with the auxiliary rack, thereby locking the abutment block. At this time, the rotation stroke of the tension plate is completed. When the cam is in the closed position, the spring is compressed, and the spring is compressed, so the spring will produce a certain resistance to the sliding of the sliding plate, that is, the torque of the elastic handle will increase when it is switched from the closed position to the open position, and when it is switched from the open position to the closed position, the sliding of the sliding plate will be assisted by the spring, which reduces the torque when the elastic handle is rotated; it can ensure that closing is easier and faster, and opening is relatively difficult, so as to prevent the elastic handle from opening due to accidental touch, thereby affecting the installation stability of the replaceable component.

[0022] A cabinet structure for a gradient amplifier includes a cabinet body, on which a plurality of horizontally arranged frames are vertically arranged, and also includes the above-mentioned quick release mechanism, wherein the quick release mechanism is relatively arranged between adjacent frames, and the two quick release mechanisms between adjacent frames fix replaceable components.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Turn the tensioning handle, and the linkage plate of the tensioning handle abuts against the abutment column. Under the action of the cam surface of the linkage plate, the abutment column moves, which drives the tensioning plate to rotate until the abutment column enters the locking concave surface. At this time, the tensioning member abuts against the movable crossbeam to fix the replaceable component. Similarly, when disassembling, just turn the tensioning handle again to quickly loosen the replaceable component.

[0025] 2. By sliding the abutment block on the tensioning plate, the abutment action at different positions of the movable beam can be adapted, which can adapt to the fixation of replaceable components of different sizes. In addition, when wear occurs between the abutment column and the tensioning handle, the rotational stroke of the tensioning handle will change. By sliding the abutment block, the abutment action of the abutment block on the movable beam can be always guaranteed;

[0026] 3. When the tensioning handle is rotated, the driving gear drives the driven gear on the abutment column to rotate, and the driven gear then drives the linkage gear to rotate. The linkage gear drives the sliding plate to slide through the connecting rod, and the sliding of the sliding plate drives the locking gear to slide. The locking gear engages with the auxiliary rack on the abutment block to lock the abutment block. Otherwise, the abutment block will slip, affecting the tightening effect.

[0027] 4. In the open state, the locking teeth and the baffle are in contact, and the abutment spring is in a compressed state. When the tensioning handle is turned, the abutment spring assists the movement of the sliding plate, making it easier for the user to turn the tensioning handle. When the handle is moved from the closed state to the open state, the sliding plate drives the locking teeth and the baffle to abut against each other, and then when the sliding plate continues to slide, the abutment spring is compressed. At this time, the abutment spring generates resistance to the sliding of the sliding plate, which can prevent the tensioning handle from rotating due to accidental touch, affecting the installation stability of the replaceable component.

[0038] The following is combined with Figure 1-9 This application is described in further detail.

[0039] An embodiment of the present application discloses a quick tightening and loosening mechanism for a replaceable component of a gradient amplifier.

[0040] Example 1

[0041] Reference Figure 1 and Figure 2The quick release and tightening mechanism of the replaceable component of the gradient amplifier includes a fixed beam 1, a movable beam 2, a release plate 3 and a release handle 4 arranged on the frame 30. The fixed beam 1 is fixed to the frame 30 by screws, and the movable beam 2 is slidably connected to the frame 30. A limit plate 5 is formed on the side where the fixed beam 1 and the movable beam 2 are away from each other, and an installation space 51 for installing replaceable components is formed between the two limit plates 5; one end of the release plate 3 is hinged to the frame 30, and the release plate 3 is located on the side where the movable beam 2 is away from the fixed beam 1. A tightening member 6 that is pressed against the movable beam 2 is provided on the side of the release plate 3 close to the movable beam 2, and an abutment column 7 is fixedly installed on the end of the release plate 3 away from the hinge point.

[0042] The tensioning handle 4 is hinged on the frame 30, and a linkage plate 8 is formed at the end of the tensioning handle 4, which abuts against the abutting column 7. A cam surface 81 and a locking concave surface 82 are formed on the linkage plate 8. When the tensioning handle 4 is rotated, the abutting column 7 is driven to move under the action of the cam surface 81, that is, the tensioning plate 3 is driven to rotate until the abutting column 7 enters the locking concave surface 82. At this time, the tightening member 6 is pressed against the movable beam 2, and the movable beam 2 cooperates with the fixed beam 1 to fix the replaceable component.

[0043] In practice, each replaceable component corresponds to two sets of quick tightening mechanisms, one set at the top and one set at the bottom, which simultaneously fix the replaceable component. By turning the tightening handle 4, the replaceable component can be quickly fixed and loosened, and the disassembly and assembly efficiency is higher.

[0044] The tightening member 6 is configured as a tightening bolt 61 , and a plurality of tightening bolts 61 are provided. Two are taken as an example in this application. The two tightening bolts 61 are fixed on the tensioning plate 3 and abut against the movable beam 2 to fix the replaceable component.

[0045] Gaskets 11 are installed on both the movable beam 2 and the fixed beam 1. The gaskets 11 are made of plastic with a low friction coefficient. The gaskets 11 can reduce the friction of the replaceable components during disassembly and assembly, thereby reducing damage to the replaceable components.

[0046] Reference Figure 1 and Figure 3 Both ends of the movable beam 2 are fixedly connected with L-shaped sliders 21 by screws. A sliding groove 22 is formed between the L-shaped slider 21 and the movable beam 2. The sliding groove 22 and the frame 30 slide together. The sliding of the movable beam 2 on the frame 30 can be achieved by external force. When installing replaceable components, the movable beam 2 can be slid to the side away from the fixed beam 1, so that the installation space 51 becomes larger, which is convenient for quickly placing replaceable components.

[0047] The quick-release mechanism for a replaceable component of a gradient amplifier according to the present embodiment of the present application operates as follows: By rotating the handle, the cam surface 81 of the linkage plate 8 drives the abutment post 7 to move, thereby rotating the release plate 3 until the abutment post 7 enters the locking recess 82. At this point, the tightening bolt 61 abuts against the movable crossbeam 2, clamping and securing the replaceable component. In other words, simply rotating the release handle 4 allows the replaceable component to be released or tightened, thereby improving the efficiency of assembly and disassembly of the replaceable component.

[0048] Example 2

[0049] This embodiment differs from the first embodiment in that the abutment post 7 is rotatably connected to the tensioning plate 3. When the tensioning handle 4 is rotated, the linkage plate 8 drives the abutment post 7 to move, generating friction between the linkage plate 8 and the abutment post 7. Long-term tensioning and loosening actions can cause wear on the surface of the abutment post 7 or the linkage plate 8, affecting the tensioning effect of the tensioning plate 3 on the moving crossbeam 2. The rotation of the abutment post 7 can reduce the friction between the linkage plate 8 and the abutment post 7, thereby helping to reduce wear between the abutment post 7 and the linkage plate 8 and ensuring the tensioning effect.

[0050] Example 3

[0051] Reference Figure 4 、 Figure 5 and Figure 6 The difference between this embodiment and embodiment 2 is that the tightening member 6 is configured as a tightening block 62, the tightening block 62 slides on the elastic plate 3, and a compression spring 31 is installed in the elastic plate 3. The length direction of the compression spring 31 is consistent with the sliding direction of the tightening block 62. One end of the compression spring 31 is connected to the tightening block 62, and the other end is connected to the inner wall of the elastic plate 3. A locking member for locking the tightening block 62 is provided on the elastic plate 3.

[0052] Under normal circumstances, when the tension plate 3 rotates, the abutment block 62 first abuts against the movable crossbeam 2, and then the abutment block 62 slides relative to the tension plate 3, compressing the compression spring 31. When the tension plate 3 finishes rotating, the locking member locks the abutment block 62. At this time, the abutment block 62 abuts against the movable crossbeam 2, thereby securing the replaceable component.

[0053] When wear occurs between the tensioning handle 4 and the abutment column 7, the rotational travel of the tensioning plate 3 will decrease, resulting in an inability to abut against the moving beam 2. This problem can be solved by the sliding of the abutment block 62 in this embodiment. The sliding of the abutment block 62 can adapt to the different spacings between the tensioning plate 3 and the moving beam 2. The abutment block 62 can always abut against the moving beam 2 to ensure the fixing effect of the replaceable component. In addition, when the size of the replaceable component changes slightly, the setting of the abutment block 62 also ensures the fixing of the replaceable component.

[0054] The locking member is provided as a locking tooth 9, which is slidably connected to the inside of the tension plate 3. An auxiliary rack 621 is integrally formed on the side of the abutment block 62. The locking tooth 9 slides and engages with the auxiliary rack 621 to lock the abutment block 62. When the tension handle 4 is fully rotated, that is, when the tension plate 3 has fully rotated, the locking tooth 9 is in engagement with the auxiliary rack 621.

[0055] Reference Figure 4 、 Figure 5 and Figure 7 The linkage plate 8 is formed with a plurality of continuous drive teeth 83 on the side of the cam surface 81. The drive teeth 83 are distributed along the contour of the cam surface 81. A driven gear 71 is coaxially fixed to the abutment column 7. When the tensioning handle 4 is rotated, the drive teeth 83 and the driven gear 71 engage. The tensioning plate 3 is rotatably connected to the linkage gear 32, which meshes with the driven gear 71. The linkage gear 32 is hingedly connected to the linkage gear 32. The hinge point between the linkage gear 321 and the linkage gear 32 is eccentric to the linkage gear 32. The tensioning plate 3 is slidably connected to the sliding plate 10. The end of the connecting rod 321 away from the linkage gear 32 is hingedly connected to the sliding plate 10.

[0056] Reference Figure 5 、 Figure 6 and Figure 8 A sliding groove 622 is provided in the middle of the abutting block 62. The sliding plate 10 slides in cooperation with the sliding groove 622. The height of the sliding groove 622 is greater than that of the sliding plate 10, that is, the abutting block 62 can slide relative to the sliding plate 10. A sliding groove 101 is provided on the sliding plate 10. The sliding groove 101 is a T-shaped groove. The lower end of the locking tooth 9 is in the shape of a T-shaped block. The lower end of the locking tooth 9 slides in cooperation with the sliding groove 101. The sliding plate 10 is located in the sliding groove 101 and is installed with an abutting spring 102. The abutting spring 102 is located on the side of the locking tooth 9 close to the abutting block 62. One end of the abutting spring 102 is connected to the inner wall of the sliding groove 101, and the other end is connected to the locking tooth 9. A baffle 33 is also fixedly connected to the elastic plate 3. The baffle 33 is located on the side of the locking tooth 9 away from the abutting block 62. In the open state, the locking tooth 9 abuts against the baffle 33, and the abutting spring 102 is in a compressed state.

[0057] From the open state to the closed state, the tensioning handle 4 is rotated, the driving tooth 83 drives the driven gear 71 to rotate, the driven gear 71 drives the linkage gear 32 to rotate, and the linkage gear 32 drives the sliding plate 10 to slide in the direction away from the linkage gear 32 through the connecting rod 321. At this time, because the abutment spring 102 is in a compressed state, the abutment spring 102 acts on the locking tooth 9, and the locking tooth 9 will continue to maintain abutment with the baffle 33, and the sliding plate 10 and the locking tooth 9 will slide relative to each other. When the abutment spring 102 is fully released, the abutment spring 102 has no force acting on the locking tooth 9, and the sliding plate 10 will drive the locking tooth 9 to slide synchronously until the locking tooth 9 and the auxiliary rack 621 are engaged, thereby locking the abutment block 62. And when the abutment column 7 enters the locking concave surface 82, the driving tooth 83 and the driven gear 71 disengage. When the abutment column 7 enters the locking concave surface 82, the abutment column 7 will rotate slightly with the cooperation of the locking concave surface 82. Through the setting of the abutment spring 102, after the locking tooth 9 and the auxiliary rack 621 are engaged, the sliding plate 10 can slide slightly and the abutment spring 102 is stretched. At this time, the force of the abutment spring 102 acts on the locking tooth 9, so that the locking tooth 9 and the auxiliary rack 621 are more tightly engaged, thereby improving the locking effect.

[0058] From the closed state to the open state, the tensioning handle 4 is reversed, the sliding plate 10 slides in the opposite direction, and the locking tooth 9 slides accordingly. When the locking tooth 9 abuts against the baffle 33, the sliding plate 10 continues to slide. At this time, the abutting spring 102 is compressed until the tensioning handle 4 stops rotating.

[0059] In addition, when gradually opening, the sliding plate 10 slides, the abutment spring 102 is compressed, and the abutment spring 102 produces a certain resistance to the sliding of the sliding plate 10, that is, the torque of the tensioning handle 4 will increase when it moves from the closed state to the open state; and when moving from the open state to the closed state, under the action of the abutment spring 102, the sliding of the sliding plate 10 is assisted, that is, the torque when the tensioning handle 4 rotates is reduced; this ensures that closing is relatively easy, quick closing and relatively difficult opening, and prevents the tensioning handle 4 from opening due to accidental touch, affecting the installation stability of the replaceable component.

[0060] Reference Figure 9 The embodiment of the present application further discloses a cabinet structure of a gradient amplifier, including a cabinet body 20, on which a plurality of frames 30 are vertically mounted, and the frames 30 are horizontally arranged; and further includes a plurality of quick release mechanisms according to any of the above embodiments, wherein quick release mechanisms are relatively mounted between adjacent frames 30, and the two quick release mechanisms between adjacent frames 30 fix the replaceable components.

[0061] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
