[0032] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0033] This invention provides a mobile express delivery weighing scanner, such as... Figure 1-12 As shown, the mobile express weighing scanner includes: a scanner body 1, which is composed of a housing 101, a column, a weighing device 102, a counter 103, a scanner 104, a display 105, and a keyboard 106. The column and the weighing device 102 are both mounted on the housing 101. The counter 103, scanner 104, display 105, and keyboard 106 are all mounted on the column, with the scanner 104 located at the top of the column. A set of brackets 2 are rotatably mounted on one side of the housing 101. A first electric telescopic rod 3 is fixedly mounted at the bottom of the set of brackets 2. Auxiliary wheels 4 are mounted at the bottom of the set of first electric telescopic rods 3 to assist in supporting the scanner body 1. A guide rod 5 is provided on one side of the housing 101 to adjust the tilt angle of the set of brackets 2. A height adjustment mechanism is provided inside the housing 101 to adjust the height of the set of guide rods 5. A cleaning mechanism is provided on the housing 101 to clean impurities on the weighing device 102.

[0034] In this embodiment, when using the scanner body 1, first place the express package on the platform of the weighing device 102, ensuring that the item is stable and does not exceed the platform range. Then, use the scanner 104 to scan the barcode or QR code of the item and input it into the device. Select the appropriate unit of measurement, such as kilograms or pounds, according to actual needs. After confirming that the item information and the unit of measurement are correct, press the "Start Measurement" button. The device will automatically perform the weighing and measurement operation. During the measurement process, do not move or interfere with the item to avoid affecting the measurement results. After the measurement is completed, the device will display the weight, size and other information of the item. The operator can then perform subsequent operations as needed.

[0035] When moving the scanner body 1, the guide rod 5 first slides upward through the height adjustment mechanism, while the bracket 2 opens outward simultaneously. Then, the first electric telescopic rod 3 is activated, causing the auxiliary wheel 4 to touch the ground and form an additional support point. In this way, even on uneven roads, the scanner body 1 can remain stable and is not easy to tip over. With the setting of the bracket 2 and the auxiliary wheel 4, the scanner body 1 can be more stable during transportation, reducing the risk of tipping over due to uneven terrain. Through the design of the height adjustment mechanism and the guide rod 5, the scanner body 1 can adapt to different slopes and terrains, improving the versatility and flexibility of the equipment.

[0036] In a further preferred embodiment of the present invention, the height adjustment mechanism includes: a U-shaped plate 6 fixedly installed inside the housing 101; a first one-way screw 7 rotatably installed on the U-shaped plate 6 for driving the guide rod 5 to move up and down; a slider 8 threaded onto the first one-way screw 7, the slider 8 being fixedly connected to the guide rod 5; a driving mechanism disposed on the U-shaped plate 6 for driving the first one-way screw 7 to rotate; and a fixing mechanism disposed on one side of the housing 101 for fixing the bracket 2.

[0037] In this embodiment, when it is necessary to adjust the tilt angle of the bracket 2, the first one-way screw 7 is first driven to rotate by the drive mechanism. The rotation of the first one-way screw 7 causes the slider 8 to move up and down. Since the slider 8 is fixedly connected to the guide rod 5, the guide rod 5 also slides up and down. The up and down sliding of the guide rod 5 changes the tilt angle of the bracket 2, which in turn affects the contact state between the auxiliary wheel 4 and the ground. Finally, the bracket 2 is fixed in the required position by the fixing mechanism to ensure stability during transportation. Through the threaded engagement of the first one-way screw 7 and the slider 8, the position of the guide rod 5 can be precisely adjusted, thereby ensuring the accuracy of the tilt angle of the bracket 2. With the introduction of the height adjustment mechanism, the bracket 2 can adaptively adjust according to changes in terrain, providing more stable support for the scanner body 1.

[0038] In a further preferred embodiment of the present invention, the driving mechanism includes: a first sprocket 9 fixedly sleeved on the first one-way screw 7; a guide wheel 10 rotatably mounted on the U-shaped plate 6; a first chain 11 sleeved on the first sprocket 9, the first chain 11 meshing with the first sprocket 9 and the guide wheel 10; and a first motor 12 fixedly mounted inside the housing 101, the output shaft of the first motor 12 being fixedly connected to the first one-way screw 7.

[0039] In this embodiment, since there is one set of auxiliary wheels 4, the number of first one-way screws 7 is the same as the number of auxiliary wheels 4. In this embodiment, each first one-way screw 7 is equipped with a corresponding first sprocket 9. When the first motor 12 starts, its output shaft rotates and drives the first one-way screw 7 fixed to it to rotate. Since the first sprocket 9 is fixedly connected to the first one-way screw 7, the first sprocket 9 also rotates. Then, the power is transmitted to other first sprockets 9 through the first chain 11 to realize the synchronous rotation operation of a set of first one-way screws 7. In this way, all supports 2 will be opened or closed at the same time to ensure the stable support of the scanner body 1. Through the setting of the first chain 11, the synchronous rotation operation of a set of first one-way screws 7 is realized, ensuring the synchronicity and stability of the supports 2 when adjusting the tilt angle.

[0040] In a further preferred embodiment of the present invention, the fixing mechanism includes: a connecting box 13 fixedly installed on one side of the housing 101, the connecting box 13 being disposed above the bracket 2; a second electric telescopic rod 14 fixedly installed inside the connecting box 13; and a fixing frame 15 installed at the bottom of the second electric telescopic rod 14 for fixing the bracket 2, the bottom of the fixing frame 15 being in close contact with the bracket 2.

[0041] In this embodiment, after adjusting the tilt angle of the bracket 2, the user activates the second electric telescopic rod 14. The second electric telescopic rod 14 extends downward, causing the fixing frame 15 to move downward. When the bottom of the fixing frame 15 is in close contact with the bracket 2, the second electric telescopic rod 14 stops extending. At this time, the bracket 2 is limited between the guide rod 5 and the fixing frame 15, thus fixing the bracket 2. Through the design of the fixing mechanism, the bracket 2 can be firmly fixed in the required position after the angle is adjusted, avoiding the risk of tipping over due to shaking or bumps during transportation, and improving the stability of the scanner body 1. The introduction of the second electric telescopic rod 14 simplifies the fixing operation. The user can complete the fixing and release of the bracket 2 with simple start and stop operations, improving work efficiency. The design of the fixing frame 15 has a certain degree of flexibility and can be adjusted according to the shape and size of the bracket 2 to ensure close contact and effective fixing.

[0042] In a further preferred embodiment of the present invention, a magnet plate 16 is installed on one side of the bracket 2, the magnet plate 16 is attracted to the guide rod 5, and the bottom of the fixing frame 15 is inclined.

[0043] In this embodiment, when the bracket 2 is adjusted to the required angle by the guide rod 5, the attraction between the magnet plate 16 and the guide rod 5 provides an additional fixing force for the bracket 2, enhancing the stability of the bracket 2 after the angle is adjusted. The inclined design at the bottom of the fixing frame 15 allows it to better adapt to different angles of the bracket 2, ensuring the best fit effect during fixing, improving the adaptability and flexibility of the equipment. The inclined bottom design also helps to disperse stress, reducing the risk of damage to the bracket 2 or fixing frame 15 due to excessive local pressure.

[0044] In a further preferred embodiment of the present invention, the cleaning mechanism includes: a second one-way screw 17 rotatably installed inside the housing 101; a connecting plate 18 threaded onto the second one-way screw 17 and passing through the top of the housing 101; a cleaning brush 19 inserted into the connecting plate 18 for cleaning impurities on the weighing device 102; a second sprocket 20 fixedly sleeved on the second one-way screw 17, with a second chain 21 sleeved on the second sprocket 20; and a second motor 22 fixedly installed on the top of the inner wall of the housing 101, with the output shaft of the second motor 22 fixedly connected to the second one-way screw 17.

[0045] In this embodiment, when it is necessary to clean the impurities on the weighing device 102, the user starts the second motor 22. The output shaft of the second motor 22 rotates, driving the second one-way screw 17 fixed thereto to rotate. The rotating second one-way screw 17 drives the connecting plate 18 to move back and forth inside the housing 101 through the thread action. Since the connecting plate 18 passes through the top of the housing and is connected to the cleaning brush 19, the cleaning brush 19 also slides back and forth on the weighing device 102. The sliding of the cleaning brush 19 removes the impurities on the weighing device 102, keeping it clean. By driving the second one-way screw 17 to rotate through the second motor 22, the automatic movement of the cleaning brush 19 is realized, simplifying the cleaning operation and improving work efficiency. The design of the cleaning brush 19 allows it to fit closely to the surface of the weighing device 102, effectively removing impurities and keeping the weighing device 102 clean and accurate.

[0046] In a further preferred embodiment of the present invention, a mounting groove is provided on one side of the connecting plate 18, a connecting spring 24 is fixedly installed in the mounting groove, a positioning block 25 is fixedly installed at one end of the connecting spring 24, the positioning block 25 extends out of the connecting plate 18, and the positioning block 25 is in close contact with the upper surface of the cleaning brush 19.

[0047] In this embodiment, when the cleaning brush 19 needs to be replaced, the user first needs to push the positioning block 25 away from its tight contact with the upper surface of the cleaning brush 19. This can be achieved by manually pushing the positioning block 25. At this time, the connecting spring 24 will be compressed to its limit. After the positioning block 25 is fully pushed into the mounting groove, the fixed relationship between the cleaning brush 19 and the connecting plate 18 is released, and the user can easily remove the cleaning brush 19 from the connecting plate 18. The design of the positioning block 25 and the connecting spring 24 makes the replacement of the cleaning brush 19 very simple and quick. The user can easily complete the replacement of the cleaning brush 19 without using tools or performing complicated operations. Since the replacement of the cleaning brush 19 is simple, the user can remove the cleaning brush 19 for cleaning more frequently, which helps to maintain the cleanliness of the weighing device 102 and improve cleaning efficiency.

[0048] In a further preferred embodiment of the present invention, the top of the positioning block 25 is inclined, and an arc plate 23 is provided inside the housing 101. The arc plate 23 is located above the second one-way screw 17, and the arc plate 23 is slidably connected to the connecting plate 18.

[0049] In this embodiment, when the user needs to install the cleaning brush 19, only a slight pushing force matching the inclined surface of the positioning block 25 is applied to easily push the positioning block 25 into the mounting slot. At the same time, the cleaning brush 19 is inserted into the connecting plate 18. The arc plate 23 is designed to guide the sliding path of the connecting plate 18, ensuring that the connecting plate 18 can move smoothly and accurately along the predetermined path under the drive of the second one-way screw 17. At the same time, the arc plate 23 can also prevent impurities from falling onto the second one-way screw 17.

[0050] In a further preferred embodiment of the present invention, a support plate 26 is fixedly installed on the top of the housing 101, an alarm 27 for alerting the cleaning mechanism during operation is rotatably installed on the support plate 26, and a protective box 28 for protecting the alarm 27 is fixedly installed on one side of the support plate 26.

[0051] In this embodiment, when the cleaning mechanism starts running, the alarm 27 rotates synchronously and extends out of the protective box 28. The alarm 27 emits warning signals (such as sound and light) to remind people not to place express packages on the weighing device 102. This warning helps to prevent express packages from interfering with the normal operation of the cleaning mechanism, ensuring the cleaning effect and equipment safety. The introduction of the alarm 27 allows people to receive timely warnings when the cleaning mechanism is running, avoiding placing express packages on the weighing device 102 due to misoperation or negligence, thereby improving equipment safety. Through the synchronous rotation and warning signals of the alarm 27, users can intuitively understand the operating status of the cleaning mechanism, thereby arranging the operation process more rationally and improving work efficiency. The design of the protective box 28 provides additional protection for the alarm 27, avoiding damage or malfunction caused by external factors (such as collisions, dust, etc.), and extending the service life of the alarm 27.

[0052] In a further preferred embodiment of the present invention, the rotating shaft of the alarm 27 and the support plate 26 are both provided with differential wheels 29, the two differential wheels 29 mesh with each other, and a third sprocket 30 is fixedly sleeved on the rotating shaft of the differential wheel 29 on the support plate 26 and on the second one-way screw 17. A third chain 31 is sleeved on the two third sprockets 30, and a protective cover 32 for protecting the third sprockets 30 and the third chain 31 is installed on one side of the support plate 26.

[0053] In this embodiment, when the cleaning mechanism starts operating, i.e., when the second one-way screw 17 starts rotating, it drives the differential wheel 29 on the support plate 26 to rotate via the third sprocket 30 and the third chain 31. Due to the design of the differential wheel 29, although the differential wheel 29 on the shaft of the alarm 27 meshes with the differential wheel 29 on the support plate 26, there is a difference in their rotational speeds. This differential setting allows the alarm 27 to slowly rotate out of the protective box 28 instead of suddenly popping out. The alarm 27 that rotates out slowly can emit a warning signal more smoothly, while giving people enough time to notice the warning and take appropriate action. Through the setting of the differential wheel 29, the alarm 27 can slowly and smoothly rotate out of the protective box 28, avoiding the fright or injury that may be caused by sudden popping out, thus improving the safety of the equipment. The alarm 27 that rotates out slowly can emit a warning signal more continuously, giving people enough time to notice the warning and take appropriate action, thereby more effectively avoiding safety problems caused by misoperation or negligence.

[0054] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments:

[0055] In another embodiment of the present invention, a switch device 33 for turning the alarm 27 on and off is fixedly installed inside the protective box 28, and a contact rod 34 is installed on the alarm 27.

[0056] In this embodiment, when the cleaning mechanism starts operating, the alarm 27 slowly rotates out of the protective box 28 under the transmission of the differential wheel 29, the third sprocket 30, and the third chain 31. During this process, the contact rod 34 gradually approaches the switch device 33 as the alarm 27 rotates. When the contact rod 34 contacts the switch device 33, the switch is triggered, the circuit is closed, and the alarm 27 starts working, emitting a warning signal. By introducing the design of the switch device 33 and the contact rod 34, the automatic activation of the alarm 27 is achieved. This design not only simplifies the operation process but also improves the automation level of the equipment, making the warning signal more timely and accurate. Since the alarm 27 is activated at the same time as it rotates out of the protective box 28, people can hear the warning signal at the same time as they see the alarm 27. This dual visual and auditory warning method enhances the warning effect and helps to attract people's attention and take action.

[0057] In another embodiment of the present invention, a telescopic handle 35 is rotatably provided on one side of the box 101, an L-shaped block 36 for placing the telescopic handle 35 is fixedly installed on one side of the box 101, and a screw rod 37 for fixing the telescopic handle 35 is rotatably installed on one side of the L-shaped block 36.

[0058] In this embodiment, when the scanner body 1 needs to be moved, the user only needs to rotate the telescopic handle 35 to make it vertical and adjust it to a suitable length. Then, the user can hold the telescopic handle 35 to move the scanner body 1. This design makes the movement process easier and less strenuous. When the scanner body 1 does not need to be moved, the user can fold the telescopic handle 35 back into a horizontal state and put it into the L-shaped block 36. The telescopic handle 35 is fixed by rotating the screw rod 37, ensuring that it will not take up too much space or cause safety hazards during storage. The design of the telescopic handle 35 makes the movement of the scanner body 1 more convenient and less strenuous. The user can adjust the length and angle of the handle as needed to adapt to different usage scenarios and height requirements. The L-shaped block 36 and the screw rod 37 work together to provide a reliable storage and fixing position for the telescopic handle 35. This design not only saves space but also avoids safety hazards caused by the handle during storage.

[0059] In another embodiment of the present invention, a limiting block 38 for limiting the telescopic handle 35 is fixedly installed on one side of the housing 101, an installation box 39 is fixedly installed on one side of the housing 101, a trapezoidal block 40 is fixedly installed on one side of the telescopic handle 35, the trapezoidal block 40 is movably connected to the installation box 39, a connecting rod 41 is fixedly installed inside the installation box 39, a connecting block 42 is slidably sleeved on the connecting rod 41, a locking block 43 is fixedly installed on one side of the connecting block 42, and the locking block 43 is used to fix the trapezoidal block 40.

[0060] In this embodiment, when the telescopic handle 35 is in a vertical position, the trapezoidal block 40 is simultaneously inserted into the mounting box 39. Then, by moving the connecting block 42, the locking block 43 is engaged in the slot of the trapezoidal block 40, thereby fixing the telescopic handle 35. Through the cooperation of the limiting block 38 and the mounting box 39, the telescopic handle 35 can be initially and finally limited to ensure that it will not shake or tip over in a vertical position. This design improves the stability of the device, allowing users to use the telescopic handle 35 to transport the scanner body 1 with greater peace of mind.

[0061] In another embodiment of the present invention, a return spring 44 is sleeved on the connecting rod 41, and the two ends of the return spring 44 are fixedly connected to the mounting box 39 and the connecting block 42 respectively. A pull rope 45 is installed on the connecting block 42, and the pull rope 45 extends out of the mounting box 39.

[0062] In this embodiment, when it is necessary to reset the telescopic handle 35, the user can pull the pull rope 45, causing the pull rope 45 to drive the connecting block 42 to slide along the connecting rod 41. As the connecting block 42 slides, the locking block 43 will gradually move away from the locking groove of the trapezoidal block 40 until the trapezoidal block 40 is completely released. At the same time, the reset spring 44 is stretched. At this time, the user can rotate the telescopic handle 35 to rotate it out of the mounting box 39 and fold it to the side of the box 101 for storage.

[0063] In summary, compared with related technologies, this express weighing scanner effectively improves the safety and stability during the transportation process through the design of its auxiliary support system.
