Description

Technical Field

[0001] The invention belongs to the technical field of inductor installation, in particular to an inductor plastic shell fixing device. Background Art

[0002] An inductor is a component that can convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to that of a transformer, but it has only one winding. An inductor has a certain inductance and only blocks the change of current. If there is no current passing through the inductor, it will try to block the current from flowing through it when the circuit is connected. Therefore, a plastic shell is needed to protect the inductor.

[0003] At present, when installing the two groups of coils of the inductor into the inner side of the equipment frame, it is necessary to use positioning blocks to provide support for the two groups of coils, wherein the positioning blocks and the equipment frame are connected by bolts and nuts. On the one hand, since the positioning blocks and the equipment frame are connected by bolts and nuts, the installation process of the two groups of coils is relatively cumbersome. On the other hand, when a group of coils fails and needs to be replaced and maintained, it is necessary to disassemble the bolt and nut assembly to release the support state of the positioning blocks for the two groups of coils, and then remove the faulty coils. However, at this time, the other group of coils that do not need to be replaced and maintained will also lose the supporting effect, thereby causing the coils that do not need to be replaced and maintained to become loose, thereby affecting their normal work.

[0041] See also Figure 1 , Figure 2 , Figure 3 as well as Figure 7The present embodiment provides an inductor plastic shell fixing device, including an equipment frame 10, a top support plate 20, a driving assembly 30, an adjusting assembly 40 and a limiting assembly 60. The top support plate 20 is provided with two groups, and the two groups of the top support plates 20 are movably arranged inside the equipment frame 10 and distributed up and down. The driving assembly 30 is installed on the side wall of the equipment frame 10. The adjusting assembly 40 is arranged inside the driving assembly 30, and is used to adjust the driving state of the driving assembly 30, so that the driving assembly 30 is in a first driving state and a second driving state. When the driving assembly 30 is in the first driving state, the driving assembly 30 can drive a group of the top support plates 20 located above to move along the The equipment frame 10 moves upward inside to support a group of coils located above to the inner top wall of the equipment frame 10.

When the upper group of coils fails and needs to be replaced and maintained, the lower group of support plates 20 are limited by the limiting assembly 60, thereby preventing the upper coils from loosening during the replacement process. Similarly, when the lower group of coils fails and needs to be replaced and maintained, the upper group of support plates 20 are limited by the limiting assembly 60, thereby preventing the upper coils from loosening during the replacement process.

[0043] See also Figure 1 as well as Figure 5In one embodiment, the driving assembly 30 includes a rotating drum 301, a tooth plate 302, an arc plate 303 and an oblique support rod 305. One end of the rotating drum 301 is rotatably connected to the inner wall of the equipment frame 10, and the other end extends horizontally toward the two groups of top support plates 20. The tooth plates 302 are provided with a plurality of groups, and a plurality of the tooth plates 302 are movably embedded on the circumferential side walls of the rotating drum 301. The plurality of the tooth plates 302 are distributed along the length direction of the rotating drum 301. Each group of the tooth plates 302 is provided with an external thread on one side facing the outside of the rotating drum 301. The arc plates 303 are provided with two groups, and the two groups of the arc plates 303 are respectively attached to the rotating drum 301. On the upper and lower sides, the arc-shaped inner walls of each group of the arc plates 303 are provided with internal threads that can cooperate with the external threads on one side of the plurality of tooth plates 302. The diagonal support rods 305 are provided with two groups, and one end of the two groups of diagonal support rods 305 are respectively hingedly connected to one group of the arc plates 303, and the other ends are respectively hingedly connected to one group of the top support plates 20. The adjustment assembly 40 includes an adjustment rod 401 and an adjustment wheel 402. The adjustment wheel 402 is arranged inside the rotating drum 301, one end of the adjustment rod 401 is fixedly connected to the adjustment wheel 402, and the other end extends to the outside of the rotating drum 301, and the diameter of the adjustment wheel 402 is smaller than the inner diameter of the rotating drum 301.

[0044] After placing a group of coils on the upper part of the top support plate 20, the staff can push up the adjustment rod 401, thereby driving the adjustment wheel 402 to move upward along the inside of the rotating drum 301, so that the adjustment wheel 402 contacts the inner top wall of the rotating drum 301, and then rotate the rotating drum 301, and the rotating drum 301 drives a plurality of tooth plates 302 to rotate. When the tooth plates 302 rotate to the upward position, the tooth plates 302 are squeezed by the adjustment wheel 402, and the external threads on the side walls of the tooth plates 302 can cooperate with the internal threads on the arc-shaped inner wall of the upper arc-shaped plate 303, thereby driving the upper arc-shaped plate 303 to move along the length direction of the rotating drum 301, thereby pushing the corresponding diagonal support rods 303. 05, the diagonal support rod 305 pushes the upper support plate 20, so that the upper support plate 20 moves up along the inner side of the equipment frame 10, and then supports the coil on its upper part to the inner top wall of the equipment frame 10, so as to realize the installation and fixation of the upper coil. When the above-mentioned several tooth plates 302 are rotated to the downward position of the drum 301, since the tooth plates 302 at this time will not contact the adjusting wheel 402, the tooth plates 302 will not obtain stable support, and the external threads on the side walls of the tooth plates 302 cannot cooperate with the internal threads on the arc-shaped inner wall of the lower arc-shaped plate 303, thereby not driving the lower arc-shaped plate 303 to move along the length direction of the drum 301; the upper coil After the fixation is completed, the staff places the lower coil at the bottom of the lower top support plate 20, and then presses down the adjusting rod 401, thereby driving the adjusting wheel 402 to move downward along the inside of the rotating drum 301, and the adjusting wheel 402 contacts the inner bottom wall of the rotating drum 301, and then rotates the rotating drum 301 again, thereby driving a plurality of tooth plates 302 to rotate again. When the tooth plates 302 are rotated to the downward position, the tooth plates 302 are squeezed by the adjusting wheel 402, and the external threads on the side walls of the tooth plates 302 can cooperate with the internal threads on the arc-shaped inner wall of the arc-shaped plate 303 below, thereby driving the arc-shaped plate 303 below to move along the length direction of the rotating drum 301, thereby pushing the corresponding inclined plate 302 to rotate. The support rod 305 and the diagonal support rod 305 push the top support plate 20 below, so that the top support plate 20 below moves down along the inner side of the equipment frame 10, and then supports the coil below it to the inner bottom wall of the equipment frame 10, so as to realize the installation and fixation of the coil below. When the above-mentioned several tooth plates 302 are rotated to the upward position of the rotating drum 301, since the tooth plates 302 at this time will not contact the adjusting wheel 402, the tooth plates 302 will not obtain stable support. The external threads on the side walls of the tooth plates 302 cannot cooperate with the internal threads on the arc-shaped inner wall of the upper arc-shaped plate 303, thereby not driving the upper arc-shaped plate 303 to move along the length direction of the rotating drum 301.

[0045] See also Figure 1 In one embodiment, a first guide rail 101 is fixedly provided on the inner side wall of the equipment frame 10, and first slide bars 201 are fixedly provided on the side walls of the two groups of top support plates 20. The ends of the two groups of first slide bars 201 away from the corresponding top support plates 20 are slidably matched with the bottom guide rail 101.

[0046] When the drum 301 rotates and the arc plate 303 is driven to move through the tooth plate 302, the first slide bar 201 and the first guide rail 101 slide together, so that the support plate 20 can move smoothly and steadily along the inside of the equipment frame 10, and then smoothly support the coil to the upper and lower side walls inside the equipment frame 10, so that the coil can be smoothly installed and fixed.

[0047] See also Figure 6 In one embodiment, a hand wheel 306 is fixedly provided on the side wall of the rotating drum 301 . The hand wheel 306 allows the staff to conveniently rotate the rotating drum 301 .

[0048] See also Figure 4 In one embodiment, a vertically distributed slot 102 is opened on the side wall of the equipment frame 10, and the end of the adjusting rod 401 away from the adjusting wheel 402 passes through the equipment frame 10 from the slot 102, so that the staff can conveniently operate the adjusting rod 401, thereby driving the adjusting wheel 402 to move up and down inside the drum 301.

[0049] See also Figure 6 In one embodiment, an elastic support component 50 is further provided on the outer wall of the rotating drum 301, and the elastic support component 50 is used to provide elastic support for the tooth plate 302, so that after the tooth plate 302 rotates and disengages from the adjusting wheel 402, the tooth plate 302 moves toward the inner side of the rotating drum 301 under the elastic support of the elastic support component 50, thereby further avoiding the external thread on one side of the tooth plate 302 from matching with the internal thread on the arc-shaped inner wall of the corresponding arc plate 303.

[0050] See also Figure 6 In one embodiment, the elastic support assembly 50 includes a second elastic member 501 and an L-shaped support plate 502, and the L-shaped support plate 502 is provided with a plurality of groups, and the plurality of L-shaped support plates 502 correspond one to one to the plurality of tooth plates 302, and the plurality of L-shaped support plates 502 are fixedly arranged on the outer wall of the rotating drum 301, and one side of each group of the L-shaped support plates 502 is connected to a group of the tooth plates 302 through a group of the second elastic member 501, and the second elastic member 501 is used to provide elastic support to the tooth plates 302.

[0051] When the adjusting wheel 402 contacts the inner top wall of the drum 301, the plurality of tooth plates 302 rotate with the drum 301, and the tooth plates 302 act on the adjusting wheel 402 to stably contact the upper arc plate 303, and the external threads on the side walls of the tooth plates 302 stably cooperate with the internal threads on the arc inner wall of the upper arc plate 303, thereby driving the upper arc plate 303 to move smoothly along the length direction of the drum 301, and then pushing the upper supporting plate 20 upward through the diagonal support rod 305 to achieve the top support fixation of the upper coil, and after the tooth plate 302 is separated from the adjusting wheel 402, the second elastic member 502 supports the tooth plate 302, and the tooth plate 302 can move toward the inside of the drum 301 to prevent the tooth plate 302 from contacting the lower arc plate 303, thereby avoiding driving the lower arc plate 303 to move along the length direction of the drum 301; When the adjusting wheel 402 contacts the inner bottom wall of the drum 301, the plurality of tooth plates 302 rotate with the drum 301, and the tooth plates 302 act on the adjusting wheel 402 and thus stably contact the arc plate 303 below. The external threads on the side walls of the tooth plates 302 stably cooperate with the internal threads on the arc-shaped inner walls of the arc plates 303 below, thereby driving the arc plates 303 below to move smoothly along the length direction of the drum 301, and then pushing the top support plate 20 below to move downward through the diagonal support rod 305 to achieve the top support fixation of the coil below. After the tooth plates 302 are separated from the adjusting wheel 402, the tooth plates 302 can move toward the inside of the drum 301 through the supporting effect of the second elastic member 502 on the tooth plates 302, so as to prevent the tooth plates 302 from contacting the arc plates 303 above, thereby avoiding driving the arc plates 303 above to move along the length direction of the drum 301.

[0052] See also Figure 5 , Figure 7 as well as Figure 8 In one embodiment, a supporting cross plate 103 is fixedly provided on the inner side wall of the equipment frame 10, a second guide rail 104 and a limiting rack 105 are fixedly provided at the bottom of the supporting cross plate 103, a second sliding bar 304 is fixedly provided on the side of the arc plate 303 away from the rotating drum 301, and one end of the second sliding bar 304 away from the arc plate 303 is slidably matched with the second guide rail 104, the limiting assembly 60 includes a limiting rod 601, a support seat 602, a third elastic member 604 and an end block 604, the support seat 602 is fixedly provided on one side of the second sliding rod 304, the limiting rod 601 vertically penetrates the support seat 602 and movably cooperates with the support seat 602, one end of the limiting rod 601 is provided with an inclined surface, and the other end is fixedly connected to the end block 604, one end of the third elastic member 604 is connected to the support seat 602, and the other end is connected to the end block 604, which is used to provide elastic tension to the limiting rod 601.

[0053] When the adjusting wheel 402 contacts the inner top wall of the rotating drum 301, so that the outer thread of the side wall of the toothed plate 302 cooperates with the inner thread of the arc inner wall of the upper arc plate 303, the rotating drum 301 rotates to drive the upper arc plate 303 to move along the length direction of the rotating drum 301, and the corresponding second sliding rod 304 slides along the second guide rail 104, and the second sliding rod 304 drives the limiting rod 601 to move synchronously, and the inclined surface at one end of the limiting rod 601 repeatedly acts on the teeth of the limiting rack 105, thereby repeatedly moving up and down compared to the support seat 602, and the third elastic member 603 is repeatedly stretched. When the upper supporting plate 20 supports the coil on its upper part to the inner top wall of the equipment frame 10, one end of the limiting rod 601 is finally inserted between two adjacent groups of teeth of the limiting rack 105, thereby performing a non-return limit on the limiting rod 601. After the limiting rod 601 is limited, the upper supporting plate 20 is limited to the current position, thereby providing stable support for the upper coil, and at the same time In principle, when the adjusting wheel 402 contacts the inner bottom wall of the rotating drum 301 so that the outer thread of the side wall of the toothed plate 302 cooperates with the inner thread of the arc inner wall of the lower arc plate 303, the rotating drum 301 rotates to drive the lower arc plate 303 to move along the length direction of the rotating drum 301, and the corresponding second slide bar 304 slides along the second guide rail 104, and the second slide bar 304 drives the limiting rod 601 to move synchronously, and the inclined surface at one end of the limiting rod 601 repeatedly acts on the limiting rack 105. The third elastic member 603 is repeatedly stretched, and when the lower supporting plate 20 supports the coil below it to the inner bottom wall of the equipment frame 10, one end of the limiting rod 601 is finally inserted between two adjacent groups of teeth of the limiting rack 105, thereby performing a non-return limit on the limiting rod 601. After the limiting rod 601 is limited, the lower supporting plate 20 is restricted to the current position, thereby providing stable support for the coil below.

[0054] See also Figure 7 as well as Figure 8 In one embodiment, a supporting vertical plate 106 is fixedly provided at the bottom of the supporting horizontal plate 103 , and one side of the supporting vertical plate 106 is connected to the second sliding rod 304 through a first elastic member 107 , and the first elastic member 107 is used to provide elastic tension to the second sliding rod 304 .

[0055] When the upper coil needs to be replaced and maintained, the adjusting rod 401 can be pushed to drive the adjusting wheel 402 to move to the middle position inside the rotating drum 301, and then the corresponding limiting rod 601 is pulled. The limiting rod 601 moves relative to the corresponding supporting seat 602, so that one end of the limiting rod 601 is removed from between two adjacent groups of teeth of the limiting rack 105 to release the limiting state of the second sliding rod 304 and the corresponding arc plate 303. At this time, since the adjusting wheel 402 is in the middle position inside the rotating drum 301, This adjusting wheel 402 does not provide support for the toothed plate 302, and the second elastic member 501 can push the toothed plate 302 so that the external thread on the side wall of the toothed plate 302 does not contact the internal thread on the arc-shaped inner wall of the arc-shaped plate 303. The second elastic member 107 can pull the corresponding second sliding rod 304, thereby driving the corresponding arc-shaped plate 303 to move in the opposite direction along the outside of the rotating drum 301, and then pull the upper supporting plate 20 through the diagonal supporting rod 305, so that the upper supporting plate 20 moves downward to release the supporting state of the upper coil; similarly When the upper coil needs to be replaced and maintained, the adjusting rod 401 can be pushed in the same manner, thereby driving the adjusting wheel 402 to move to the middle position inside the drum 301, and then pulling the corresponding limiting rod 601, the limiting rod 601 moves relative to the corresponding supporting seat 602, so that one end of the limiting rod 601 is removed from between two adjacent sets of teeth of the limiting rack 105, so as to release the limiting state of the second sliding rod 304 and the corresponding arc plate 303. At this time, since the adjusting wheel 402 is in the middle position inside the drum 301 Therefore, the adjusting wheel 402 does not provide support for the toothed plate 302, and the second elastic member 501 can push the toothed plate 302 so that the external thread on the side wall of the toothed plate 302 does not contact the internal thread on the arc-shaped inner wall of the arc-shaped plate 303. The second elastic member 107 can pull the corresponding second sliding rod 304, thereby driving the corresponding arc-shaped plate 303 to move in the opposite direction along the outside of the rotating drum 301, and then pull the lower supporting plate 20 through the diagonal supporting rod 305, so that the lower supporting plate 20 moves up to release the supporting state of the lower coil.

[0056] In one embodiment, the first elastic member 107 , the second elastic member 501 and the third elastic member 603 may be springs or metal springs, which are not limited here.

[0057] In the embodiment of the present invention, when two groups of coils need to be installed into the equipment frame 10, one group of coils can be placed on the upper part of the top support plate 20, and then the driving component 30 can be adjusted to the first driving state by using the adjusting component 40. The driving component 30 drives the group of top support plates 20 located above to move upward, and then the coils at the upper part are supported on the inner top wall of the equipment frame 10. Then, the other group of coils is placed on the bottom of the top support plate 20 located below, and then the driving component 30 is adjusted to the second driving state by using the adjusting component 40. The driving component 30 drives the group of top support plates 20 located below to move downward, and then the coils at the lower part are supported on the inner bottom wall of the equipment frame 10, thereby realizing the installation and fixation of the two groups of coils. When a group of coils located at the top fails and needs to be replaced and maintained, the group of top support plates 20 located at the bottom are limited by the limit assembly 60, thereby preventing the upper coils from becoming loose due to the replacement process. Similarly, when a group of coils located at the bottom fails and needs to be replaced and maintained, the group of top support plates 20 located at the top are limited by the limit assembly 60, thereby preventing the upper coils from becoming loose due to the replacement process. Compared with the prior art, the two groups of coils can be conveniently supported and fixed. At the same time, when a group of coils needs to be replaced and maintained, the group of coils can be conveniently disassembled, and the disassembly process does not affect the fixing state of the other group of coils.

[0058] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
