Detailed implementation mode

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and the implementation mode:

[0027] As Figures 1 to 6 shown, an adjusting structure for an identification sign device includes a bottom box 1. A support rod 3 is connected to the top of the bottom box 1. A sliding square groove 4 is arranged inside the support rod 3. A reciprocating screw rod 5 is rotatably connected inside the sliding square groove 4. The lower end of the reciprocating screw rod 5 is rotatably connected to the bottom box 1 and penetrates into the inside of the bottom box 1. A moving block 3 is movably connected to the reciprocating screw rod 5. The moving block 3 is slidably connected to the sliding square groove 4. The sliding square groove 4 can play a role in rotating and limiting the moving block 3. The moving block 3 is connected to a moving rod 6. The moving rod 6 is slidably connected to the sliding square groove 4. The moving rod 6 is connected to a protective rod 7. The protective rod 7 is slidably connected to the support rod 3. The top of the protective rod 7 is connected to a mounting rod 8. A driven gear 11 is rotatably connected to the mounting rod 8. The driven gear 11 is connected to a connecting sleeve 10. The connecting sleeve 10 is also rotatably connected to the mounting rod 8. The connecting sleeve 10 is connected to an identification plate 9. An auxiliary rod 13 is rotatably connected to the protective rod 7. The auxiliary rod 13 is connected to a driving gear 12. The driving gear 12 meshes with the driven gear 11. A servo motor 25 is connected to the inside of the bottom box 1. The output shaft of the servo motor 25 is connected to a first rotating rod 22. The first rotating rod 22 is connected to a second ratchet disc 16. The bottom of the reciprocating screw rod 5 is connected to a fixed square rod 21. The cross-section of the fixed square rod 21 is rectangular. A first connecting rod 19 is slidably connected to the fixed square rod 21. The first connecting rod 19 is slidably connected to the fixed square rod 21 through a set square groove. The first connecting rod 19 is connected to a first ratchet disc 15. A fixed block 30 is connected to the reciprocating screw rod 5. A first spring 31 is sleeved on the reciprocating screw rod 5. The two ends of the first spring 31 are respectively connected to the fixed block 30 and the first connecting rod 19. The first ratchet disc 15 and the second ratchet disc 16 cooperate with each other;

[0028] A second rotating rod 23 is rotatably connected to the inner side of the bottom box 1, and the second rotating rod 23 is connected to the third ratchet toothed disc 18. The first rotating rod 22 and the second rotating rod 23 are respectively connected to the transmission sprocket 24, and the two sets of transmission sprockets 24 are commonly connected to the transmission chain 26. The bottom box 1 is rotatably connected to the transmission square rod 14, and the cross-section of the transmission square rod 14 is rectangular. The transmission square rod 14 is slidably connected to the auxiliary rod 13, and the auxiliary rod 13 is slidably connected to the transmission square rod 14 through the set square groove. The lower side of the transmission square rod 14 is slidably connected to the second connecting rod 20, and the second connecting rod 20 is connected to the fourth ratchet toothed disc 17. The fourth ratchet toothed disc 17 cooperates with the third ratchet toothed disc 18. The transmission square rod 14 is sleeved with a second spring 32, and the two ends of the second spring 32 are respectively connected to the transmission square rod 14 and the second connecting rod 20. The ratchet teeth direction of the fourth ratchet toothed disc 17 is opposite to the ratchet teeth direction of the first ratchet toothed disc 15.

[0029] Taking the first ratchet toothed disc 15 and the second ratchet toothed disc 16 as an example, Figure 2 and Figure 5 As shown, the first ratchet toothed disc 15 is meshed with the second ratchet toothed disc 16 under the action of the first spring 31 to Figure 5 For example, when the second ratchet gear rotates clockwise, due to the setting of the ratchet teeth, the first ratchet tooth plate 15 will not drive the second ratchet tooth plate 16 to rotate when it rotates clockwise, but will resist the upward movement of the first ratchet tooth plate 15, and the first ratchet tooth plate 15 can also move upward because it is slidably connected to the fixed square rod 21, so that the second ratchet tooth plate 16 rotates clockwise and the first ratchet tooth plate 15 does not move; when the second ratchet tooth plate 16 rotates counterclockwise, because the first ratchet tooth plate 15 is engaged with the second ratchet tooth plate 16 under the action of the first spring 31, and due to the corresponding setting of the ratchet teeth, the counterclockwise rotation of the second ratchet tooth plate 16 will drive the first ratchet tooth plate 15 to rotate counterclockwise; the rotation transmission direction of the third ratchet tooth plate 18 and the fourth ratchet tooth plate 17 is opposite to the rotation transmission direction of the first ratchet tooth plate 15 and the second ratchet tooth plate 16.

[0030] The reciprocating screw 5 is connected to a bearing plate 33, and the bearing plate 33 is rotatably connected to the bottom box 1 through a bearing capable of bearing radial loads; the bottom box 1 is connected to an electric telescopic rod 29, and the electric telescopic rod 29 is connected to a resistance block 28, and the resistance block 28 is slidably connected to the first connecting rod 19; through the electric telescopic rod 29 and the resistance block 28, the first ratchet toothed disc 15 can always be engaged with the second ratchet toothed disc 16, so that the first ratchet toothed disc 15 can rotate counterclockwise or clockwise with the second ratchet toothed disc 16, and the bottom box 1 is provided with a mounting hole 27 for inserting bolts, and the bottom box 1 is connected to a box door 2.

[0031] When the abutment block 28 does not abut the first ratchet toothed plate 15, the first ratchet toothed plate 15 and the second ratchet toothed plate 16 are in a state of meshing with each other through the elastic force of the first spring 31. At this time, the servo motor 25 drives the first rotating rod 22 to rotate counterclockwise, thereby driving the second ratchet toothed plate 16 and the transmission sprocket 24 connected to the first rotating rod 22 to rotate counterclockwise. Through the transmission of the transmission sprocket 24 and the transmission chain 26, the second rotating rod 23 also rotates counterclockwise with the first rotating rod 22. The counterclockwise rotation of the second ratchet toothed plate 16 drives the first ratchet toothed plate 15 to rotate counterclockwise, and the second The third ratchet toothed disc 18 will also rotate counterclockwise with the second rotating rod 23, but at this time the third ratchet toothed disc 18 will not drive the fourth ratchet toothed disc 17 to rotate counterclockwise, so the transmission square rod 14 will not rotate, and the rotation of the first ratchet toothed disc 15 drives the fixed square rod 21 to rotate, thereby driving the reciprocating screw rod 5 to rotate. Since the moving block 3 is slidably connected with the sliding square groove 4, the moving block 3 will reciprocate up and down along the reciprocating screw rod 5 as the reciprocating screw rod 5 rotates, and the moving block 3 will drive the moving rod 6, the protective rod 7 and the mounting rod 8 to move up and down together with the moving block 3, thereby completing the marking. Height adjustment of the sign 9; in actual setting, the rotational friction between the driven gear 11 and the mounting rod 8 can be set to be larger, and the rotational friction between the transmission square rod 14 and the bottom box 1 can also be set to be larger, so at this time the driven gear 11 cannot be easily moved, and the angle of the sign 9 will not change easily; when the angle of the sign 9 needs to be adjusted, the servo motor 25 is started to drive the first rotating rod 22 to rotate clockwise, and at this time the second ratchet toothed disc 16 and the third ratchet toothed disc 18 also rotate clockwise, and the clockwise rotation of the second ratchet toothed disc 16 does not drive the first ratchet toothed disc 15 to rotate Therefore, the height of the sign 9 will not change at this time, and the third ratchet toothed disc 18 will drive the fourth ratchet toothed disc 17 to rotate, and then drive the transmission square rod 14 to rotate. The rotation of the transmission square rod 14 will drive the auxiliary rod 13 to rotate, and then drive the driving gear 12 to rotate, and then drive the driven gear 11 to rotate, and then drive the connecting sleeve 10 to rotate, thereby completing the adjustment of the angle of the sign 9; when the height of the protective rod 7 changes, the height of the auxiliary rod 13 will also change with the height of the protective rod 7, and at the same time, the auxiliary rod 13 can slide up and down relative to the transmission square rod 14 without affecting the transmission between the two.

[0032] When the reciprocating screw 5 and the transmission square rod 14 need to rotate together, the electric telescopic rod 29 is started to drive the resistance block 28 to move downward, so that the resistance block 28 resists the first ratchet gear plate 15, and the first ratchet gear plate 15 is tightly engaged with the second ratchet gear plate 16. At this time, the servo motor 25 drives the first rotating rod 22 to rotate, so that the reciprocating screw 5 and the transmission square rod 14 can rotate together.

[0033] A method for using an adjustment structure for a sign device comprises the following steps:

[0034] S1. Install the bottom box 1 through the installation holes 27 and bolts, and then complete the preliminary fixation of the sign 9. Place the device at the usage location, pass the bolts through the installation holes 27, and complete the fixation of the bolts to complete the overall installation of the device.

[0035] S2. Start the servo motor 25 to adjust the height of the sign 9 according to the above operations. The mounting rod 8 can move up and down reciprocally along the reciprocating lead screw 5 together with the moving block 3, so that the height of the mounting rod 8 can be adjusted. At this time, the angle of the sign 9 will not change.

[0036] S3. Start the servo motor 25 to adjust the angle of the sign 9 according to the above operations. At this time, the height of the sign 9 will not change.

[0037] When the reciprocating lead screw 5 and the transmission square rod 14 need to rotate together, make the abutting block 28 move down to drive the first ratchet tooth disc 15 and the second ratchet tooth disc 16 to engage tightly. When subsequent maintenance of the device is required, the box door 2 can be opened to maintain the internal structure of the bottom box 1 and so on.

[0038] The above are only embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be subject to the content of its claims, and the specific implementation manners described in the specification can be used to explain the content of the claims.
