[0037] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.
[0038] A wax film printer that can prevent illegal maintenance, referring to Figure 1 , including a printer body, a housing 1 and a combination lock 2. In this embodiment, an inspection port is provided on the housing 1, and two baffles are rotatably connected to the inspection port, and the inspection port is blocked by the two baffles. The printer body is arranged in the housing 1. Limiting rings are fixedly connected to the side walls of the two baffles, and the combination lock 2 fixes the two limiting rings to limit the rotation between the two baffles, thereby limiting the maintenance of the wax film printer.
[0039] Reference Figure 1 and Figure 2 The combination lock 2 includes a lock ring 21, a lock body 22 and a housing 23. The lock ring 21 is U-shaped. The lock ring 21 passes through two limiting rings and is inserted into the lock body 22, and is fixed to the lock body 22, thereby limiting the two housings 1. When the lock needs to be unlocked, the correct password is entered on the lock body 22 to release the limit of the lock ring 21.
[0040] The shell 23 is hollow inside, and the lock body 22 is arranged in the shell 23. There are several lock bodies 22, and the several lock bodies 22 are all arranged in the shell 23. The unlocking password of each lock body 22 is different. In order to facilitate the manufacturer to distinguish the password corresponding to each lock body 22, the outer wall of the lock body 22 can be marked with a serial number to distinguish different lock bodies 22.
[0041] A turntable 4 is rotatably connected in the housing 23, and a plurality of lock bodies 22 are fixedly connected to the turntable 4 and evenly arranged along the turntable 4. A window is provided at the beginning of the outer wall of the housing 23, and the window is used to display a lock body 22, so that the lock body 22 at the window position can enter a password to unlock the lock. During the rotation of the turntable 4, a plurality of lock bodies 22 will pass through the window position in sequence, and the lock ring 21 will be inserted into the housing 23 and into the lock body 22 at the window position.
[0042] When the wax film printer needs to be repaired, the manufacturer sends professional maintenance personnel and informs the maintenance personnel of the unlocking code of the lock body 22 at the window position. After the maintenance personnel unlocks the lock, the turntable 4 rotates to replace the lock body 22 at the window, thereby changing the unlocking code. When the maintenance personnel completes the maintenance, they insert the lock ring 21 into the lock body 22 at the window to complete the limiting of the housing 1. At this time, because of the replacement of the lock body 22, the maintenance personnel cannot open the combination lock 2, thereby reducing the possibility of maintenance personnel performing maintenance privately.
[0043] In this embodiment, the lock body 22 is unlocked using a roller-type password. When the lock ring 21 and the lock body 22 are out of engagement, maintenance personnel are required to manually disrupt the password of the lock body 22 and then pull out the lock ring 21 to change the position of the lock body 22.
[0044] Reference Figure 2 and Figure 3 A driving device 3 is provided in the housing 23, and the driving device 3 is used to drive the rotating disk 4 to rotate. The driving device 3 includes a rack 31, a first gear 32 and a second gear 33. The rack 31 is fixedly connected to the side wall of the lock ring 21, the first gear 32 is sleeved on the rotating disk 4 and fixedly connected to the rotating disk 4, the second gear 33 is rotatably connected in the housing 23 and meshes with the first gear 32, and a connecting device 5 is provided between the rack 31 and the second gear 33, and the rack 31 can drive the second gear 33 to rotate in one direction through the connecting device 5.
[0045] Reference Figure 3 and Figure 4 The connecting device 5 includes a third gear 51 and a limiting assembly 52. The third gear 51 is rotatably connected to the second gear 33. The limiting assembly 52 is used to limit the relative rotation of the third gear 51 and the second gear 33. When the lock ring 21 is disengaged from the lock body 22, the rack 31 is engaged with the third gear 51. At this time, the lock ring 21 is continued to be pulled, the rack 31 drives the third gear 51 to rotate, the third gear 51 drives the second gear 33 to rotate, thereby driving the first gear 32 to rotate, and the first gear 32 drives the turntable 4 to rotate. When the lock ring 21 is pulled out of the housing 23, the rack 31 is separated from the third gear 51, and the next lock body 22 rotates to the window position.
[0046] The limiting assembly 52 includes a limiting rod 521, a limiting block 522 and an elastic member 523. A limiting hole 331 is opened on the second gear 33. One end of the limiting rod 521 is fixedly connected to the third gear 51, and the other end of the limiting rod 521 is inserted into the limiting hole 331 and is rotatably connected to the inner wall of the limiting hole 331.
[0047] The inner wall of the limiting hole 331 is provided with a telescopic slot 332. In this embodiment, there are several telescopic slots 332. Each of the telescopic slots 332 is slidably connected with a limiting block 522. An elastic member 523 is provided between each limiting block 522 and the inner wall of the telescopic slot 332. One end of the elastic member 523 acts on the limiting block 522, and the other end of the elastic member 523 acts on the inner wall of the telescopic slot 332. Each limiting block 522 is provided with a guide slope 5221, and the orientation of each guide slope 5221 is the same. A push rod 524 is fixedly connected to the side wall of the limiting rod 521. There are several push rods 524, and the several push rods 524 are evenly arranged around the limiting rod 521. One of the above-mentioned push rods 524 is inserted between each group of adjacent limiting blocks 522.
[0048] When the third gear 51 rotates counterclockwise, it abuts against the limit block 522, thereby driving the second gear 33 to rotate. When the third gear 51 rotates clockwise, it abuts against the guide slope 5221. The limit block 522 slides into the telescopic groove 332 under the guidance of the guide slope 5221, and the second gear 33 does not rotate.
[0049] In this embodiment, in order to reduce the rotation of the second gear 33 when the limit block 522 slides into the telescopic slot 332, a damping member is provided between the second gear 33 and the inner wall of the shell 23 to increase the friction between the second gear 33 and the shell 23.
[0050] In order to reduce the wear of the push rod 524 and the guide inclined surface 5221, a roller is rotatably connected to the side wall of the push rod 524. The roller contacts the guide inclined surface 5221 to reduce the friction between the push rod 524 and the guide inclined surface 5221, thereby reducing the wear of the push rod 524 and the limit block 522.
[0051] The implementation principle of the embodiment of the present application is: when the wax film printer needs to be repaired, a maintenance personnel is sent to repair it, and the password of the lock body 22 at the window position is informed. After the maintenance personnel enters the password, the lock body 22 releases the limit of the lock ring 21.
[0052] Pull the lock ring 21, when the lock ring 21 is disengaged from the lock body 22, the rack 31 is meshed with the third gear 51, and the lock ring 21 is continued to be pulled, so that the rack 31 drives the third gear 51 to rotate, and drives the turntable 4 to rotate through the second gear 33 and the first gear 32, when the lock ring 21 is disengaged from the housing 23, the rack 31 is disengaged from the third gear 51, and the other lock body 22 moves to the window position. Disengage the lock ring 21 from the limit ring, and then start repairing the wax film printer.
[0053] When the lock ring 21 is inserted into the shell 23, the rack 31 meshes with the third gear 51, driving the third gear 51 to rotate. The third gear 51 rotates, causing the ball to contact the guide slope 5221, so that the limit block 522 slides into the telescopic groove 332, and then the second gear 33 is not driven to rotate by the third gear 51. When the lock ring 21 is inserted into the lock body 22, the locking of the combination lock 2 is completed.
[0054] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
