Description

Technical Field

[0001] This utility model relates to the field of cabinet door wire storage, and more specifically, to a cabinet door wire pull-back mechanism. Background Technology

[0002] In the current commercial and public service sectors, self-service equipment such as vending machines, smart book lending machines, and smart express delivery lockers have been widely used. These devices are usually equipped with locker doors, and in order to improve the user experience and achieve clear human-computer interaction, manufacturers generally integrate a display screen on the inside or front of the locker door to display product information, operation instructions, and advertising content.

[0003] In order for the display screen to work properly, it must be connected to the communication module and power supply located in the main cabinet of the equipment via wires. Since the cabinet door needs to be opened and closed frequently, the wires connecting the display screen cannot be rigidly connected. Sufficient length and slack must be reserved inside the cabinet to accommodate the displacement when the cabinet door is opened. This design currently generally uses a direct connection method with cables or ribbon cables.

[0004] With the development of technology, in order to enhance the technological feel and transparency of equipment, some equipment has begun to adopt transparent displays. This design allows users to see the products displayed inside the cabinet or the internal structure while operating the interface, thus improving the intuitiveness and fun of the interaction.

[0005] However, this transparent design also introduces a new problem: the wires that were originally hidden inside the cabinet can be clearly seen by users through the transparent display screen. These wires reserved for opening and closing the cabinet door are usually quite messy, which seriously affects the overall aesthetics and technological feel of the equipment and reduces the perceived quality of the product. More importantly, these long wires are at risk of being squeezed and pinched by the cabinet door hinges or edges during repeated opening and closing of the cabinet door. Over time, this can easily lead to wear and tear on the insulation layer of the wires and breakage of the internal metal wires, thereby causing the display screen to malfunction, short circuit, or even safety hazards.

[0006] Therefore, it is necessary to propose a cabinet door guide wire pull-back mechanism to solve the above problems. Utility Model Content

[0007] To overcome at least one of the defects (deficiencies) of the prior art described above, this utility model provides a cabinet door guide wire pull-back mechanism.

[0008] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a cabinet door wire pull-back mechanism, including an automatic pull rope device, a steering wheel, and a wire protection tube for protecting the wire;

[0009] The automatic rope puller is wound with a pull rope, and the wire protection tube is provided with an installation and connection device. After the pull rope on the automatic rope puller is wound around the steering wheel, it is fixed on the installation and connection device.

[0010] After passing through the mounting connection device on the wire protection tube, the wire exits from the first end of the tube. Since existing book lending machines have displays on their doors and allowances are made for the wire to be extended when the door is opened, the wire, after passing through the mounting connection device, exits from the first end of the tube and connects to the display screen. In practical applications, the mounting connection device secures the wire as it passes through, thus maintaining a fixed distance between the display screen on the door and the mounting connection device. When the door opens, the outward pulling force is greater than the inward pulling force of the automatic pull cord mechanism. Therefore, opening the cabinet door will pull the wire protection tube and installation connection device forward. At this time, the pull rope on the automatic pull rope device is pulled out, and the reserved wires inside the cabinet will also be pulled out at the same time, thus ensuring that the display screen on the cabinet door remains connected to the equipment inside the cabinet. When the cabinet door is closed, under the action of the automatic pull rope device, the wire protection tube, installation connection device and reserved wires will be pulled to the back of the cabinet and hidden by the automatic pull rope device, thus making the borrowing area at the front of the book lending machine tidier. When people look at the books inside the cabinet through the display screen, they will not see the messy wires inside the cabinet, enhancing the user experience. In addition, it can also effectively prevent the risk of wires being pinched or broken.

[0011] Furthermore, the mounting connection device includes a mounting connection block and mounting holes;

[0012] The mounting connection block is set on the inner wall of the wire protection tube, the mounting hole is set on the wire protection tube, and the pull rope on the automatic pull rope device is fixed on the mounting hole after passing through the steering wheel.

[0013] The mounting connector has a through hole extending along the inner wall of the wire protection tube. After the wire passes through the through hole, it exits from the first end of the wire protection tube. The mounting hole can be used to fix the automatic rope puller, while the mounting connector can be used to pass the wire through and fix the wire.

[0014] Furthermore, it also includes perforated holes and support rods;

[0015] The hollow hole is provided on the mounting connecting block and is connected to the communicating hole;

[0016] The support rod is set in the hollow hole, and the wire is tied to the support rod with cable ties. The hollow hole allows the wire passing through the mounting block to be exposed, while the support rod supports the wire and makes it easy to tie the wire to the support rod with cable ties. Of course, in practical applications, a silicone or hollow sleeve made of silicone material can also be set on the wire for positioning. The cooperation of the hollow sleeve and cable ties can better fix the wire to the support rod.

[0017] Furthermore, the support rod is provided with an arc-shaped inner groove. The arc-shaped inner groove can be used to hold the wire in place, making it easier for cable ties and other fixing devices to tie the wire tightly to the support rod.

[0018] Furthermore, the support rod is perpendicular to the direction of the wire introduction. In practical applications, the support rod can also be inclined to the direction of the wire introduction, which are all alternative solutions that are easy for those skilled in the art to conceive of.

[0019] Furthermore, there is at least one support rod. In practical applications, the number of support rods can be set as needed, and all of these are within the protection scope of this utility model.

[0020] Furthermore, the mounting block, mounting hole, support rod, and wire protection tube are integrated into a single unit, which effectively simplifies the overall structure of the installation connection device.

[0021] Furthermore, the conductor protection tube is provided with an installation through hole that communicates with the installation connection device. The installation through hole makes it easy for people to tie the conductor to the support rod with cable ties.

[0022] Furthermore, the conductor protection tube is a corrugated tube or a square tube. In practical applications, other tubes can also be used to replace the conductor protection tube, which are all alternatives that are easy for those skilled in the art to conceive of.

[0023] Furthermore, the wire protection tube is made of a high-molecular polymer material. Wire protection tubes made of high-molecular polymer material are inexpensive and lightweight, making it easy for an automatic pull rope device to pull the wire protection tube backward and reset it.

[0024] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0025] This utility model discloses a cabinet door cable retraction mechanism. Since existing book lending machines typically have a display screen on the cabinet door and a pre-installed cable length for opening the door, the cable passes through a connecting device on a cable protection tube and exits from the tube at one end, connecting to the display screen. In practical applications, the connecting device secures the cable as it passes through, thus maintaining a fixed distance between the display screen and the connecting device. When the door opens, the outward pulling force is greater than the inward pulling force of the automatic cable puller, resulting in a more efficient opening mechanism. Pulling the wire protection tube and installation connection device forward causes the pull rope on the automatic pull rope device to extend, simultaneously pulling out the pre-installed wires inside the cabinet. This ensures that the display screen on the cabinet door remains connected to the equipment inside the cabinet. When the cabinet door is closed, the automatic pull rope device pulls the wire protection tube, installation connection device, and pre-installed wires to the rear of the cabinet, concealing them. This makes the borrowing area at the front of the book lending machine neater, and users will not see the messy wires inside the cabinet when viewing the books through the display screen, enhancing the user experience. In addition, it effectively prevents the risk of wires being pinched or broken. Attached Figure Description

Detailed Implementation

[0033] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can be described as the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0035] like Figure 1-2 As shown, a cabinet door wire pull-back mechanism includes an automatic pull rope device 1, a steering wheel 2, and a wire protection tube 4 for protecting the wire 3. A pull rope 5 is wound around the automatic pull rope device 1, and an installation connection device 6 is provided on the wire protection tube 4. The pull rope 5 on the automatic pull rope device 1 is fixed to the installation connection device 6 after passing through the steering wheel 2. The wire 3 passes through the installation connection device 6 on the wire protection tube 4 and exits from the first end of the wire protection tube 4. Since existing book lending machines have a display screen on the cabinet door and a reserved length of wire 3 for extension when opening the cabinet door is provided, the wire 3, after passing through the installation connection device 6 on the wire protection tube 4, exits from the first end of the wire protection tube 4 and connects to the display screen. In practical applications, when the wire 3 passes through the installation connection device 6, the installation connection device 6 will tighten the wire 3. Therefore, the display screen on the cabinet door... The distance between the wire 3 and the installation connection device 6 is fixed. When the cabinet door is opened, the outward pulling force of the cabinet door is greater than the inward pulling force of the automatic pull rope device 1. Therefore, the opening of the cabinet door will pull the wire protection tube 4 and the installation connection device 6 forward. At this time, the pull rope 5 on the automatic pull rope device 1 is pulled out, and the wire 3 reserved in the cabinet will also be pulled out at the same time, thereby ensuring that the display screen on the cabinet door and the equipment in the cabinet remain connected. When the cabinet door is closed, under the action of the automatic pull rope device 1, the wire protection tube 4, the installation connection device 6 and the reserved wire 3 will be pulled to the back of the cabinet and hidden by the automatic pull rope device 1. This makes the borrowing area at the front of the book lending machine tidier. When people look at the books in the cabinet through the display screen, they will not see the messy wires 3 in the cabinet, which enhances the user experience. In addition, it can also effectively prevent the risk of the wires 3 being pinched or broken.

[0036] like Figure 3-6As shown, the mounting connection device 6 includes a mounting connection block 7 and a mounting hole 8. The mounting connection block 7 is disposed on the inner wall of the wire protection tube 4, and the mounting hole 8 is disposed on the wire protection tube 4. The pull rope 5 on the automatic pull rope device 1 is fixed on the mounting hole 8 after passing through the steering wheel 2. The mounting connection block 7 has a through hole 9 that runs along the inner wall of the wire protection tube 4. After the wire 3 passes through the through hole 9, it exits from the first end of the wire protection tube 4. The mounting hole 8 can be used to fix the automatic pull rope device 1, while the mounting connection block 7 can be used to pass through the wire 3 and fix the wire 3. In this utility model, it also includes a hollow hole 10 and a support rod 11. The hollow hole 10 is disposed on the mounting connection block 7 and is connected to the through hole 9. The support rod 11 is disposed on the hollow hole 10, and the wire 3 is tied to the support rod 11 by a cable tie 12. The hollow hole 10 allows the wire 3 passing through the mounting connection block 7 to be exposed, while the support rod 11... The cable tie 12 can not only support the wire 3, but also facilitate the binding of the wire 3 to the support rod 11. Of course, in practical applications, a hollow silicone or silicone sleeve 13 for positioning can also be provided on the wire 3. Through the cooperation of the hollow sleeve 13 and the cable tie 12, the wire 3 can be better fixed to the support rod 11. The support rod 11 is provided with an arc-shaped inner groove 14. The arc-shaped inner groove 14 can play a locking role for the wire 3, so that the cable tie 12 and other fixing devices can bind the wire 3 to the support rod 11. In this utility model, the support rod 11 is perpendicular to the direction of wire 3. In practical applications, the support rod 11 can also be inclined to the direction of wire 3. These are all alternative solutions that are easy for those skilled in the art to think of. There is at least one support rod 11. In practical applications, the number of support rods 11 can be set as needed, and all of them are within the protection scope of this utility model.

[0037] In this utility model, the mounting connecting block 7, mounting hanging hole 8, support rod 11, and wire protection tube 4 are integrated into one structure. This integrated structure effectively simplifies the overall structure of the mounting connection device 6. The wire protection tube 4 has a mounting through hole 15 that communicates with the mounting connection device 6. The mounting through hole 15 allows for easy binding of the wire 3 to the support rod 11 using cable ties 12. In this utility model, the wire protection tube 4 is a corrugated tube or a square tube. In practical applications, other tubes can be used instead of the wire protection tube 4, all of which are readily conceived by those skilled in the art. The wire protection tube 4 is made of a high-molecular polymer material, which is inexpensive and lightweight, facilitating the automatic pull rope device 1 to pull the wire protection tube 4 backward and reset.

[0038] Example

[0039] In this embodiment, the cabinet door cable pull-back mechanism is used in a book lending machine. Since existing book lending machines typically have a display screen on the cabinet door and a pre-installed cable length for opening the door, the cable passes through the installation connector at the end of the cable protection tube and then exits from the end of the tube, connecting to the display screen. In practical applications, the installation connector secures the cable as it passes through the door, thus maintaining a fixed distance between the display screen and the installation connector. When the door opens, the outward pulling force is greater than that of the automatic cable pull mechanism. The pulling force causes the cabinet door to open, pulling the wire protection tube and installation connection device forward. At this time, the pull rope on the automatic pull rope device is pulled out, and the reserved wires inside the cabinet are also pulled out at the same time, thus ensuring that the display screen on the cabinet door remains connected to the equipment inside the cabinet. When the cabinet door is closed, under the action of the automatic pull rope device, the wire protection tube, installation connection device, and reserved wires are pulled to the back of the cabinet and hidden by the automatic pull rope device. This makes the borrowing area at the front of the book lending machine tidier, and people will not see the messy wires inside the cabinet when viewing the books inside the cabinet through the display screen, thus enhancing the user experience.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
