[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0025] See Figures 1 - 5 .

[0026] The utility model discloses a durable switch panel, including:

[0027] A main protective shell 1, detachably arranged on a mounting base 4. An opening 11 is formed in the middle of the main protective shell 1. A circuit board is arranged on the mounting base 4, and a button 6 and an indicator light 7 are connected to the circuit board;

[0028] A conversion component 2, including a sub-protective shell 21 rotatably arranged in the opening 11. One side of the sub-protective shell 21 away from the mounting base 4 is a first indicating surface 211, and one side of the sub-protective shell 21 close to the mounting base 4 is a second indicating surface 212. It also includes a transmission rod 22 vertically and rotatably inserted into the main protective shell 1. One end of the transmission rod 22 is connected to the sub-protective shell 21 for driving the sub-protective shell 21 to rotate around the axis of the transmission rod 22. A plurality of through holes 213 are formed in the sub-protective shell 21, and the positions of the through holes 213 correspond to the positions of the button 6 and the indicator light 7 one by one. A limiting member 23 is also arranged on the transmission rod 22, and the limiting member 23 is used to prevent the transmission rod 22 from rotating.

[0029] In specific implementation, when installing the switch panel, the main protective shell 1 is installed on the mounting base 4, and each button 6 and indicator light 7 pass through the corresponding through holes 213 and extend out of the main protective shell 1. After the long-term operation of the doubling machine, the connection at the bottom of the main protective shell 1 and the mounting base 4 is worn. At this time, the staff removes and turns the main protective shell 1 upside down, so as to switch the connection between the top and bottom of the main protective shell 1 and the mounting base 4. At this time, the transmission rod 22 drives the sub-protective shell 21 to rotate and makes the second indicating surface 212 rotate to be flush with the side of the main protective shell 1 away from the mounting base 4. Then, the limiting member 23 is used to limit the rotation of the transmission rod 22, so as to prevent the sub-protective shell 21 from accidentally rotating. Then, the main protective shell 1 is installed on the circuit board.

[0030] In the utility model, through the cooperation of the main protective shell 1 and the conversion component 2, when the connection at the bottom of the main protective shell 1 is worn, the main protective shell 1 is removed and turned over, and the sub-protective shell 21 is rotated by the transmission rod 22 to switch the positions of the second indicating surface 212 and the first indicating surface 211. At this time, the original top connection of the main protective shell 1 is connected to the bottom of the mounting base 4, which prolongs the service life of the main protective shell 1 and avoids the wear of the circuit board, ensures the production efficiency, and can reduce the replacement frequency of the main protective shell 1 to reduce the replacement cost.

[0031] It should be noted that a set of first labels 215 for identifying the positions and functions of the buttons 6 and the indicator lights 7 are provided on the first indicating surface 211. Each first label 215 is arranged below the corresponding through hole 213. Second labels 216 are provided on the second indicating surface 212 and are distributed above the through holes 213. When the first indicating surface 211 is flipped, the positions of the second labels 216 at this time correspond one by one to the positions of the first labels 215 on the first indicating surface 211 before flipping, so as to avoid the identification and indication of the buttons 6 and the indicator lights 7 being chaotic due to the misalignment of the through holes 213 after the main protective shell 1 is flipped.

[0032] In one embodiment, a groove 12 is vertically formed at the bottom end of the main protective shell 1, the transmission rod 22 passes through the groove 12, and a plurality of limiting grooves 13 are also distributed at the bottom end of the main protective shell 1;

[0033] The limiting member 23 includes a limiting frame 231 fixedly arranged on the transmission rod 22. The limiting frame 231 is arranged in a "cross" shape, and one end of the limiting frame 231 is inserted into the groove 12 and is rotatably provided with a first connecting block 232. A first elastic unit 233 is arranged between the first connecting block 232 and the groove 12. The first elastic unit 233 applies a vertically upward pulling force to the first connecting block 232. A plurality of limiting blocks 234 are also arranged on both sides of the limiting frame 231. Each limiting block 234 corresponds to each limiting groove 13 one by one. When the limiting block 234 is inserted into the limiting groove 13, the limiting block 234 is used to prevent the transmission rod 22 from rotating.

[0034] With such a design, when the sub-protective shell 21 is working, the first elastic unit 233 applies a vertically upward pulling force to the first connecting block 232 so that each limiting block 234 is inserted into the corresponding limiting groove 13 to prevent the transmission rod 22 from accidentally rotating. When it is necessary to rotate the sub-protective shell 21, the limiting frame 231 is pulled downward. The limiting frame 231 drives the first connecting block 232 and the transmission rod 22 to slide downward. At this time, the first elastic unit 233 is stretched until each limiting block 234 exits the corresponding limiting groove 13. At this time, the transmission rod 22 is rotated 180° so that the second indicating surface 212 is flush with the surface of the main protective shell 1 away from the mounting base 4. At this time, each limiting block 234 corresponds to each limiting groove 13 one by one. During the rotation of the sub-protective shell 21, the first connecting block 232 will not rotate together with the transmission rod 22, avoiding interference with the first elastic unit 233. The staff loosens the limiting frame 231, the first elastic unit 233 loses restraint and drives the first connecting block 232 to move in a direction away from the limiting frame 231. The first connecting block 232 drives the limiting frame 231 and the transmission rod 22 to move together and makes each limiting block 234 inserted into the corresponding limiting groove 13 to complete the limitation of the sub-protective shell 21, so that the first indicating surface 211 and the first indicating surface 211 on the sub-protective shell 21 can be switched quickly and conveniently.

[0035] Preferably, the first elastic unit 233 may be a tension spring in the prior art.

[0036] It should be noted that a guiding groove 14 may be vertically formed at the bottom end of the main protective case 1. The guiding groove 14 communicates with the groove 12. A guiding block 2321 may be provided on the first connecting block 232. The guiding block 2321 is vertically and slidably arranged in the guiding groove 14, so as to further ensure that when the limiting frame 231 rotates, the first connecting block 232 does not rotate with the limiting frame 231 while not affecting the rotation of the limiting frame 231, and protect the first elastic unit 233 from interference when the sub-protective case 21 rotates.

[0037] In an embodiment, multiple groups of chute groups are distributed in the sub-protective case 21. Each chute group includes a plurality of sliding grooves 214 surrounding the corresponding through hole 213, and each sliding groove 214 is formed in the sub-protective case 21.

[0038] A filling component 3 is further provided in the sub-protective case 21. The filling component 3 includes sliding plates 31 slidably arranged in the respective sliding grooves 214. One surface of each sliding plate 31 close to the center of the corresponding through hole 213 is arc-shaped and corresponds to the outer wall of the indicator light 7 in an arc shape. Both sides of each sliding plate 31 abut against the side walls on both sides of the corresponding sliding groove 214. A second elastic unit 32 is further provided between the sliding plate 31 and the corresponding sliding groove 214. The second elastic unit 32 applies a thrust force to the sliding plate 31 in the direction close to the corresponding through hole 213.

[0039] With such a design, when each indicator light 7 and button 6 pass through the corresponding through hole 213, the sliding plates 31 around the indicator light 7 abut against the outer wall of the indicator light 7. When the button 6 passes through the corresponding through hole 213, the button 6 will squeeze the surrounding sliding plates 31, causing each sliding plate 31 to contract into the corresponding sliding groove 214. The corresponding second elastic unit 32 is compressed and applies a thrust force to the corresponding sliding plate 31 in the direction of the center of the through hole 213, so that each sliding plate 31 closely adheres to the outer wall of the button 6. Thus, when the button 6 and the indicator light 7 pass through any one of the through holes 213, the sliding plates 31 around the corresponding through hole 213 can reduce the gap between the corresponding through hole 213 and the corresponding button 6 or indicator light 7, and reduce the entry of dust and impurities into the main protective case 1.

[0040] Preferably, the second elastic unit 32 may be a spring in the prior art.

[0041] In one embodiment, a first positioning block 41 is provided on the mounting base 4. The first positioning block 41 is in a "mouth" shape. A first positioning groove 15 corresponding to the first positioning block 41 is formed on one side of the main protection shell 1 close to the mounting base 4. When the first positioning block 41 is inserted into the first positioning groove 15, the first positioning block 41 is used to limit the movement of the main protection shell 1 on the mounting base 4. Second positioning blocks 42 are vertically provided on both sides of the mounting base 4. The second positioning blocks 42 are in an "L" shape. Second positioning grooves 16 are vertically formed on both sides of one side of the main protection shell 1 close to the mounting base 4 respectively.

[0042] A positioning member 5 is further provided on the main protection shell 1. The positioning member 5 includes third positioning blocks 51 vertically arranged in the respective second positioning grooves 16. Each of the third positioning blocks 51 is in an "L" shape and corresponds to one of the second positioning blocks 42. Each of the third positioning blocks 51 is rotatably arranged in the corresponding second positioning groove 16, and a torsion spring (not shown in the figure) is provided at the rotational connection of the third positioning block 51 and the corresponding second positioning groove 16. The torsion spring applies a torsion force to the corresponding third positioning block 51 in the direction close to the center of the main protection shell 1. A connecting plate 52 is vertically provided on one side of each of the third positioning blocks 51 away from the center of the main protection shell 1. The connecting plate 52 facilitates manual force application to drive the third positioning block 51 to rotate.

[0043] With such a design, when the main protection shell 1 needs to be connected to the mounting base 4, the staff applies a thrust to the corresponding third positioning blocks 51 in the direction away from the center of the main protection shell 1 through the respective connecting plates 52. At this time, each torsion spring is compressed, and the first positioning block 41 is inserted into the first positioning groove 15. At this time, each second positioning block 42 is inserted into the corresponding second positioning groove 16. The staff releases the respective connecting plates 52, and each torsion spring loses restraint and drives the corresponding third positioning block 51 to rotate in the direction close to the center of the main protection shell 1. At this time, each third positioning block 51 and the corresponding second positioning block 42 are buckled with each other. The first positioning block 41 inserted into the first positioning groove 15 is used to prevent the main protection shell 1 from moving on the mounting base 4. Each second positioning block 42 is inserted into the second positioning groove 16 and buckled with the corresponding third positioning block 51 to prevent the main protection shell 1 and the mounting base 4 from accidentally falling off. When the main protection shell 1 needs to be removed, a thrust is applied to the respective third positioning blocks 51 again in the direction away from the center of the main protection shell 1 until each third positioning block 51 is separated from the corresponding second positioning block 42, and the main protection shell 1 is moved away from the mounting base 4.

[0044] In one embodiment, a soft and wear-resistant inner lining (not shown in the figure) is provided on the first positioning block 41. The inner lining is used to reduce the wear of the main protection shell 1.

[0045] With such a design, during the operation of the doubling machine, the main wear part at the switch connection is at the bottom end of the first positioning block 41. This inner lining can prevent the first positioning block 41 from directly contacting the main protective shell 1, thereby avoiding direct friction between the first positioning block 41 and the main protective shell 1, and effectively reducing the wear of the main protective shell 1.

[0046] Preferably, the inner lining can be made of materials with good softness and wear resistance such as animal leather and foam plastics.

[0047] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. In addition, "a plurality of", "multiple groups", and "several" mean more than two.
