Description

Technical Field

[0001] The utility model relates to the field of motorcycle travel boxes, in particular to a password lock for a motorcycle travel box. Background Art

[0002] A motorcycle travel box is a storage solution designed for long-distance riders. Motorcycle travel boxes are roughly divided into several types such as metal, plastic, and composite materials. When in use, riders need to configure according to their own needs. However, a good motorcycle travel box needs to have sealing performance, durability, and stability to ensure the safety of the items inside the box and provide strong support for long-distance riders.

[0003] For existing motorcycle travel boxes, in order to store items safely, a box lock needs to be used. However, most of these box locks are mechanical locks and the corresponding keys need to be carried at all times, which brings a lot of inconvenience to travel and motorcycle trips. Moreover, there are also situations where they cannot be opened. Since motorcycle travel boxes can be divided into side boxes, tail boxes, and fuel tank bags according to their installation positions, in order to ensure the safety of stored items, we need at least three locks. If the keys to the motorcycle travel box are lost, it will cause great losses.

[0004] To solve the above problems, we have designed a password lock for a motorcycle travel box that can also be used while wearing riding gloves. Summary of the Invention

[0005] In order to overcome the disadvantages of low security and complex use of mechanical locks, the technical problem of the utility model is to provide a password lock for a motorcycle travel box that can be used while wearing riding gloves.

[0006] A password lock for a motorcycle travel box, characterized in that: it includes a bottom frame, the bottom frame is fixedly connected to the motorcycle travel box, a large rotating plate is rotatably connected to the bottom frame, a small rotating plate is rotatably connected to the large rotating plate, a hook plate is fixedly connected to the side of the small rotating plate away from the large rotating plate, a password box is fixedly connected to the side of the bottom frame away from the small rotating plate, a wheel disc is rotatably connected to the side of the password box close to the large rotating plate, a limiting frame is fixedly connected to the side of the bottom frame away from the large rotating plate, a rotating column is rotatably connected to the limiting frame, a pulley assembly is connected between the rotating column and the wheel disc, a gear is fixedly connected to the rotating column, a short rod is rotatably connected to the side of the bottom frame away from the large rotating plate, the short rod meshes with the gear, a hollow column is rotatably connected to the side of the bottom frame away from the large rotating plate, the hollow column is fixedly connected to the short rod, a long prism is slidably connected to the side of the hollow column close to the large rotating plate, and a long return spring is fixedly connected between the long prism and the hollow column.

[0007] Further explanation, a round hole plate is fixedly connected to the side of the bottom frame away from the large rotating plate, and the round hole plate is fixedly connected to the motorcycle travel box, which improves the stability between the bottom frame and the box body.

[0008] It is further explained that a rubber ring with fine texture is arranged on the surface of the long prism away from the large rotating plate to ensure that the long prism can rotate under any circumstances.

[0009] Further description, it also includes a hook plate, which is slidably connected to the side of the small rotating plate away from the large rotating plate, and the side of the small rotating plate away from the large rotating plate is slidably connected to the arc plate, the side of the arc plate away from the large rotating plate is slidably connected to the side of the hook plate close to the large rotating plate, four limit rods are fixedly connected to the side of the small rotating plate away from the large rotating plate, and a rounded plate frame is slidably connected to the limit rods, the rounded plate frame is in contact with the small rotating plate, a short reset spring is fixedly connected between the small rotating plate and the limit rod, and the rounded plate frame is in contact with the side of the arc plate close to the large rotating plate.

[0010] It is further explained that a handle is fixedly connected to the rounded corner plate frame to make it more convenient to lift the rounded corner plate so as to adjust the relative distance between the hook plate and the small rotating plate.

[0011] Further description, it also includes a limiting column, which is fixedly connected to the side of the bottom frame away from the large rotating plate, and a flip plate is rotatably connected to the limiting column on one side, and the flip plate is in contact with the limiting column on the other side, and a rounded frame is fixedly connected to the side of the flip plate away from the large rotating plate, and an arc plate is rotatably connected to the side of the flip plate away from the large rotating plate, and a sliding rod is slidably connected to the side of the flip plate away from the large rotating plate, and the sliding rod is in contact with the arc plate on the side away from the large rotating plate.

[0012] The beneficial effect of the utility model is as follows: during the use of the motorcycle travel box, people may encounter the situation of losing the key. At this time, the motorcycle travel box fixed by a mechanical lock will have safety defects, and in serious cases, it will also cause the life safety of the motorcycle tourists. In order to solve the above problems, we have designed a password lock that is easy for riders to operate according to the characteristics of motorcycle tourists. Because riders need to wear riding gloves to ensure their safety during the motorcycle travel, because wearing gloves increases the circumference of the fingers, it becomes difficult to operate. In order to ensure safe operation in this case, we set the long prism to be retractable. When people operate, they first stretch the long prism to leave a safe operating range to ensure the correct operation of each password. Because it is necessary to ensure the correct input of each password, we connect the wheel and the long prism in series through a series of transmission parts to ensure the operation of the motorcycle tourists when wearing gloves.

[0013] In order to ensure the firmness of the connection between the bottom frame and the motorcycle travel box, we set a circular hole plate on the bottom frame to connect the bottom frame more firmly to the motorcycle travel box, so as to ensure that the bottom frame will not fall off no matter how bumpy it is.

[0014] In order to ensure better and more correct operation of the device when wearing gloves, we set a rubber ring with fine patterns on the surface of the long prism, so that the friction of the surface of the long prism can be increased to ensure correct operation when wearing gloves.

[0015] When traveling by motorcycle, you will encounter long-term bumps and multiple opening and closing of the motorcycle travel box. In this process, friction occurs between the hook plate and the motorcycle travel box, and the hook plate will wear. After the locking is completed, a gap will appear between the hook plate and the motorcycle travel box, which will cause the seal of the motorcycle travel box to be loose, and the motorcycle travel box will vibrate violently. In order to solve the above problems, we set the stroke of the hook plate to be adjustable, open the rounded plate frame, and adjust the distance between the hook plate and the small rotating plate according to the gap between the hook plate and the box body. After the adjustment is completed, release the rounded plate frame, clamp the arc plate, and use the pressure of the short reset spring to fix the arc plate to ensure the normal use of the hook plate.

[0016] In order to ensure the safe lifting and lowering of the rounded corner plate rack, we fixed a handle on the rounded corner plate rack, so that the rounded corner plate rack can be operated more safely and easily.

[0017] The process of motorcycle travel is not static, and the motorcycle travel box will encounter different environments. In order to ensure that no foreign objects enter the lock and affect the use of the lock during driving, we need to protect the lock, so we first fix the large rotating plate with a flip plate, and then use the rounded frame connected to the flip plate to protect the main part of the lock and close it. In order to ensure the continuity of protection, we fix the flip plate on the limit column. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0028] The present utility model will be further described below in conjunction with specific embodiments. The schematic embodiments and descriptions herein are used to explain the present utility model, but not to limit the present utility model.

[0029] Embodiment 1: A password lock for a motorcycle touring box, as Figures 1 - 6 shown, includes a bottom frame 1, the bottom frame 1 is fixedly connected to the motorcycle touring box, a large rotating plate 2 is rotatably connected to the rear side of the bottom frame 1, a small rotating plate 3 is rotatably connected to the rear side of the large rotating plate 2, hook plates 301 are fixedly connected to the left and right sides of the rear part of the small rotating plate 3, a password box 4 is fixedly connected to the front part of the bottom frame 1, a roulette 5 is rotatably connected to the password box 4, a limiting frame 6 is fixedly connected to the front side of the upper wall of the bottom frame 1, a rotating column 7 is rotatably connected to the limiting frame 6, a pulley assembly 8 is connected between the rotating column 7 and the roulette 5, a gear 9 is fixedly connected to the rotating column 7, a short rod 10 is rotatably connected to the front side of the upper wall of the bottom frame 1, the short rod 10 meshes with the gear 9, a hollow column 11 is rotatably connected to the front side of the bottom frame 1, the hollow column 11 is fixedly connected to the short rod 10, a long prism 12 is slidably connected to the front part of the hollow column 11, and a long return spring 13 is fixedly connected between the long prism 12 and the hollow column 11.

[0030] When people travel by motorcycle, they will definitely use a motorcycle travel box. In order to ensure the safety of stored items, the motorcycle travel box must be locked. However, the existing mechanical locks have certain safety hazards. When the key of the box falls, people cannot take out the necessary items in the box, which will cause certain safety hazards. Therefore, it is necessary to design a password lock with a motorcycle travel box. However, for riding safety, people need to wear travel gloves. Therefore, we need a password lock that can be used in any situation. When using this device, first install the bottom frame 1 on the main body of the motorcycle travel box, then hang the hook plate 301 on the lid of the motorcycle travel box, and then rotate and press the large rotating plate 2 on the bottom frame 1, and finally control the password box 4 to lock the large rotating plate 2 by rotating the wheel 5. Because the large rotating plate 2 and the small rotating plate 3 are rotatably connected, the small rotating plate 3 will carry the hook plate 301 to firmly close the lid of the motorcycle travel box. When people need to take out the items in the motorcycle travel box, they first stretch the long prism 12 to the front side, and then rotate it clockwise. The long prism 12 will first stretch the long return spring 13. Because the long prism 12 and the hollow column 11 are interlocked, the long prism 12 will also rotate clockwise with the hollow column 11. Because the hollow column 11 and the short rod 10 are fixedly connected, the short rod 10 also rotates clockwise with the hollow column 11. Because the gear 9 and the short rod 10 are meshed with each other, and the gear 9 is fixedly connected to the rotating column 7, the rotating column 7 also rotates counterclockwise with the gear 9. Because the rotating column 7 is connected to the wheel plate 5 through the pulley assembly 8 Finally, the roulette wheel 5 rotates counterclockwise along with the rotating column 7, and stops rotating after the roulette wheel 5 rotates to the correct position. Finally, the long prism 12 is released, and the long prism 12 will retract into the hollow column 11 under the reset of the long reset spring 13, and then each long prism 12 is operated from left to right in turn. When the correct password is entered, the motorcycle travel box can be opened to take out the items. After completing one operation, the motorcycle travel box is covered, and then the long prism 12 is rotated counterclockwise to rotate the long prism 12 to other positions to ensure the safety of the motorcycle travel box.

[0031] Embodiment 2: Based on embodiment 1, Figures 1 - 4 As shown, two circular hole plates are fixedly connected to the left and right sides of the lower part of the bottom frame 1, and the circular hole plates are fixedly connected to the motorcycle travel box, thereby improving the stability between the bottom frame 1 and the box body.

[0032] In order to better fix the bottom frame 1 on the motorcycle travel box, we installed several circular hole plates on the bottom frame 1. Through the circular hole plates, the bottom frame 1 and the motorcycle travel box are reinforced again to ensure that the motorcycle travel box will not be shaken off.

[0033] like Figure 5 and Figure 6 As shown, the front end surface of the long prism 12 is provided with a rubber ring with fine textures to ensure that the long prism 12 can rotate under any circumstances.

[0034] In order to ensure that the long prism 12 can rotate safely under any circumstances, a rubber ring with fine patterns is provided on the front end surface of the long prism 12 , so that the surface friction of the long prism 12 can be improved.

[0035] like Figures 1 - 7 As shown, it also includes a hook plate 301, which is slidably connected to the left and right sides of the front of the small rotating plate 3, and the left and right sides of the front of the small rotating plate 3 are slidably connected with the arc plate 14, and the left and right sides of the arc plate 14 are slidably connected to the front side of the hook plate 301, and four limit rods 16 are fixedly connected to the rear side of the upper end of the small rotating plate 3, and a rounded plate frame 15 is slidably connected to the limit rods 16, and the rounded plate frame 15 is in contact with the small rotating plate 3, and a short reset spring 17 is fixedly connected between the small rotating plate 3 and the limit rods 16, and the rounded plate frame 15 is in contact with the inner side of the arc plate 14.

[0036] After opening and closing the motorcycle travel box for a long time, in order to prevent the hook plate 301 of the motorcycle travel box from being worn and causing a lack of sealing, in order to ensure the sealing of the motorcycle travel box, we set the hook plate 301 to be a sliding connection. When wear occurs, people can first lift the rounded plate frame 15 upwards, and the rounded plate frame 15 will slide upwards under the limit of the limit rod 16. After reaching the highest point, it will remain motionless. In this process, the short return spring 17 connected to the rounded plate frame 15 will be compressed first. When the rounded plate frame 15 slides upward, it will also disengage from the arc plate 14, releasing the limit of the arc plate 14, and then slide the arc plate 14 to the left and right sides to make the arc plate 14 disengage from the hook plate 301, and finally adjust the hook plate 301. When the adjustment is completed, the arc plate 14 is slid in the opposite direction and the hook plate 301 is fixed. After sliding into place, the rounded plate frame 15 is released, and the rounded plate frame 15 is reset by the short return spring 17, re-contacts and jams the arc plate 14, and then remains motionless, waiting for the next adjustment.

[0037] like Figure 1 As shown, a handle is fixedly connected to the upper end of the rounded corner plate frame 15, so as to more conveniently lift the rounded corner plate and adjust the relative distance between the hook plate 301 and the small rotating plate 3.

[0038] In order to better lift the rounded corner plate frame 15, a handle is fixed on the rounded corner plate frame 15, so that the operator can lift and put down the rounded corner plate frame 15 more conveniently.

[0039] like Figure 8 and Figure 9As shown in the figure, it further includes a limit post 18. The limit post 18 is fixedly connected to the left and right sides of the front part of the bottom frame 1. A turning plate 19 is rotatably connected to the left limit post 18. The right side of the turning plate 19 contacts the right limit post 18. A rounded corner frame 20 is fixedly connected to the front side of the upper end of the turning plate 19. An arc plate 21 is rotatably connected to the right side of the turning plate 19. A sliding insertion rod 22 is slidably connected to the right side of the turning plate 19. The right side of the sliding insertion rod 22 contacts the arc plate 21.

[0040] Because the password lock is a precision component, if foreign objects enter during the motorcycle tour, it will cause the lock to be unable to be opened, which will affect the safety of the operator. Therefore, after people operate the lock, they need to rotate the turning plate 19 to the right. When the turning plate 19 contacts the limit post 18, the large rotating plate 2 is fixed first. Also, because the rounded corner frame 20 is fixedly connected to the turning plate 19, after the rotation is completed, the rounded corner frame 20 will completely cover and protect the main part of the lock. To ensure the continuity of the covering, after the turning plate 19 contacts the limit post 18, the arc plate 21 is rotated upward to buckle the limit post 18, and then the sliding insertion rod 22 is moved downward and locked.

[0041] It should be understood that this embodiment is only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.
