[0024] See also Figure 1 , 2 , 3, 4, 5, and Figure 6A digital information transmission device for mobile communication includes an installation compartment 1, wherein a chain lifting mechanism 2 for driving a switch 3 to be lifted and lowered is installed inside the installation compartment 1, wherein the chain lifting mechanism 2 includes a plurality of rotating flower-shaped gears 203, and the flower-shaped gears 203 drive a front plate 204 to move by continuously shifting a connecting shaft 205, a rear plate 206 is arranged on the rear side of the front plate 204, and the connecting shaft 205 penetrates the rear plate 206 and the front plate 204 and extends to the outside thereof, a nut 207 is connected to one end of the connecting shaft 205 away from the flower-shaped gear 203, and the chain lifting mechanism 2 installs the switch 3 on its inner side through the nut 207, the front plate 204 and the installation plate 4, and the installation plate 4 is located on both sides of the switch 3.

[0025] In this embodiment, the chain lifting mechanism 2 is driven by a motor 201, which can be a servo motor or a forward and reverse motor. A worm gear reducer is installed at the output end, and the chain is driven to move as a whole through the worm gear reducer. The worm gear reducer can avoid rotation. A controller is also installed in the device. The controller and the motor are electrically connected to control the start and stop. The installation bin 1 is a four-sided open structure for convenient heat dissipation. A power supply can be set above the installation bin 1 to facilitate the connection of the switch 3. In addition, slide grooves can be opened on both sides of the front side of the installation bin 1, and a slider matching the slide groove is connected to one side of the outer baffle 701. When the chain lifting mechanism 2 is lifted or lowered, the quick release assembly 7 will also be lifted or lowered with it. In addition, the quick release assembly 7 is also assisted by a slider to make its movement smoother.

[0026] Specifically, the chain lifting mechanism 2 also includes a motor 201, and the output end of the motor 201 is connected to a pulley group 202, the pulley group 202 is located on one side of the flower-shaped gear 203, and multiple groups of flower-shaped gears 203 are driven to rotate by the pulley group 202, and a coaxial axis is set between the two horizontally symmetrical groups of flower-shaped gears 203.

[0027] In this embodiment, the pulley group 202 includes a belt and a pulley. The pulley is driven by the belt. The pulley is a multi-groove pulley. The multi-groove pulley distribution belt drives the corresponding flower-shaped gear 203 to rotate. The flower-shaped gear 203 drives the flower-shaped gear 203 on the horizontal symmetry plane to rotate through the coaxial drive. Similarly, it will also drive the front plate 204, the connecting shaft 205 and the rear plate 206 of the symmetry plane to move and perform the same movement.

[0028] Specifically, the number of front plates 204, connecting shafts 205, rear plates 206 and nuts 207 are all multiple groups, and the front plates 204 and the rear plates 206 have the same structure. The rear plate 206 is arranged between the upper and lower groups of front plates 204. Four groups of connecting shafts 205 run through the front plate 204, and the four groups of connecting shafts 205 are distributed in the front plate 204 in a parallelogram structure, wherein the connecting shaft 205 at the top is at the bottom end of the previous group of front plates 204. The number of front plates 204, connecting shafts 205, rear plates 206 and nuts 207 are all multiple groups, and the front plates 204 and the rear plates 206 have the same structure. The rear plate 206 is arranged between the upper and lower groups of front plates 204. Four groups of connecting shafts 205 run through the front plate 204, and the four groups of connecting shafts 205 are distributed in the front plate 204 in a parallelogram structure, wherein the connecting shaft 205 at the top is at the bottom end of the previous group of front plates 204.

[0029] In this embodiment, the front plate 204 and the rear plate 206 are both rectangular structures, and holes are provided inside thereof for the connecting shaft 205 to pass through. The holes at the bottom and the top are semicircular, and together they match the connecting shaft 205. After the connecting shaft 205 passes through the front plate 204, protrusions are provided on one side of the front plate 204 and the rear plate 206. The protrusion close to the side of the flower-shaped gear 203 is in contact with the flower-shaped gear 203, so when the flower-shaped gear 203 rotates, the protrusion will be moved, thereby driving the connecting shaft 205 to move. The protrusion away from the side of the flower-shaped gear 203 is for the convenience of installing the switch 3, and is connected to the mounting plate 4 on the side of the switch 3.

[0030] Specifically, the mounting plate 4 is arranged on both sides of the switch 3, and the mounting plate 4 is an "L"-shaped structure. The end of the connecting shaft 205 passes through the mounting plate 4 and is connected to it through a nut 207. A mounting portion is provided on one side of the threaded portion at the tail end of the connecting shaft 205, and a protrusion is provided on one side of the mounting portion.

[0031] In this embodiment, the mounting portion is a vacant portion for mounting the plate 4, and is preferably slightly larger than the thickness of the mounting plate 4, so that during installation, the mounting plate 4 will be located at the mounting portion, and the threaded portion will be located on the inner side of the mounting plate 4. The mounting effect can be achieved by locking the threaded portion with a nut 207. The raised portion is located on one side of the rear plate 206. The number of raised portions can be two groups, and the other group can be located on one side of the front plate 204 but will not contact the flower-shaped gear 203. The connecting shaft 205 firmly penetrates the front plate 204 and the rear plate 206 and will not move at will inside them.

[0032] See also Figure 7 , 8 , 9 and Figure 12, a digital information transmission device for mobile communication, a quick release component 7 is detachably installed on the front side of the switch 3 through the gear rack and limit, a pressing component 8 linked with the gear rack is installed on the inner side of the quick release component 7, and the pressing component 8 can press the cable head protrusion to make it normally enter and escape from the cable groove in the switch 3, the pressing component 8 includes a transmission gear 801, and a transmission belt 802 is arranged on the rear side of the transmission gear 801, the transmission belt 802 drives the hinged connecting rod 805 to rotate through the bevel gear set 803 and the fixed block 804, and the vertically arranged downward pressing link 8056 in the hinged connecting rod 805 passes through the penetrating seat 806 and is connected to the pressing block 807 at the bottom, and the pressing block 807 contacts the cable head protrusion.

[0033] In this embodiment, the cable slot on one side of the switch 3 matches the cable, and the head protrusion needs to be pressed to insert it. One side of the switch 3 not only has a cable slot but also a power hole, and the power hole is connected to the power head. The cable hole, the power hole and the through holes distributed in the inner baffle 703 match each other. The power plug can be inserted without pressing the protrusion, but the pressing process does not delay the insertion process.

[0034] Specifically, the two sides of the switch 3 are slidably connected with the lead bin 5, and the lead bin 5 is a hollow structure, a connection hole is opened on one side below the lead bin 5, and a through hole is opened above the lead bin 5, and a tooth limit group 6 is installed on the top of the switch 3, the tooth limit group 6 includes a tooth portion and a slide groove portion located below the tooth portion, the tooth portion and the transmission gear 801 are meshed, and the transmission gear 801 is installed in the connecting side plate 704, and the connecting side plate 704 also includes a slider portion matching the slide groove portion.

[0035] In this embodiment, the lead bins 5 on both sides are for facilitating the migration of the exported cable ends along a certain path. The sliding structure of the lead bins 5 can stagger the cables of multiple sets of vertically installed switches 3 to prevent entanglement. The cables are best tied with a cable tie on the export or migration path to prevent them from becoming scattered. The cables pass through the line-aligning block 702 and are then exported from the round hole at the end of the outer baffle 701.

[0036] Specifically, there are four groups of connecting side plates 704 , wherein a card and component 705 is disposed inside the lower connecting side plate 704 , and the card and component 705 includes a card slot portion and a card block portion, and the card block portion is located at the bottom end of the slide slot portion below the switch 3 .

[0037] In this embodiment, the card slot portion and the card block portion can adopt the structure shown in the accompanying drawings or other common card and structures. The structure shown in the accompanying drawings includes: the card block portion is located at the bottom end of the chute portion at the bottom end of the switch 3, and includes a short cylindrical handle. A long cylinder is provided at the top end of the handle. A spring is provided on the outer side of the long cylinder. An arc-shaped block is provided at the top end of the long cylinder. Among them, the arc-shaped block, the long cylinder, and the spring are located in the housing, and the handle is located outside the housing. Pulling the handle can cause the long cylinder and the arc-shaped block to move downward. Because the spring is connected to the housing, the spring without force will cause the arc-shaped block to lift. The card slot portion includes a transverse cylindrical structure with two protruding ends and a middle thin cylindrical structure connecting the two protruding ends. When the connecting side plate 704 drives the card slot portion to move forward, it will reach above the arc-shaped block. As the pushing and the spring cause the transverse cylinder to press down the arc-shaped block, after continuous pushing, the arc-shaped block and the middle thin cylinder will come into contact, and both ends are blocked by the protruding transverse cylinder to achieve the purpose of clamping. When it is necessary to release the clamping state, pull the handle downward to make the arc-shaped block move downward, and then move the quick-release component 7 backward to achieve the disassembly purpose.

[0038] Specifically, the quick-release component 7 includes an outer baffle 701, and a wire-aligning block 702 is connected to the inner side of the outer baffle 701. An inner baffle 703 is provided on one side of the wire-aligning block 702, and a pressing component 8 is installed on the side of the inner baffle 703 close to the switch 3, and a locking component 9 is installed on the side of the inner baffle 703 close to the wire-aligning block 702.

[0039] In this embodiment, the outer baffle 701 is installed on one side of the inner baffle 703, and the wire-aligning block 702 is arranged in the middle of the two. The wire-aligning block 702 is closer to the outer baffle 701. The wire-aligning block 702 can align multiple groups of cables. A rectangular groove is provided in the wire-aligning block 702. After the cables pass through the rectangular groove, they are led out from the circular hole on one side of the outer baffle 701 and then tied tightly with cable ties. A reserved operation space is provided between the outer baffle 701, the wire-aligning block 702, and the inner baffle 703. The messy cables cannot be directly seen from the outside of the outer baffle 701, so to a certain extent, the purpose of avoiding cable mess is achieved.

[0040] Specifically, the bevel gear set 803 includes two sets of meshing bevel gears. One end of one set of bevel gears penetrates through the fixed block 804 and is connected to one end of the short connecting rod 8051. One end of the short connecting rod 8051 is hinged to the first long connecting rod 8052, and one end of the first long connecting rod 8052 is hinged to the intermediate connecting rod 8053. One end of the intermediate connecting rod 8053 is connected to the second long connecting rod 8054. A sleeve block 8055 is sleeved outside the second long connecting rod 8054. One end of the sleeve block 8055 is hinged to the downward pressing connecting rod 8056. The downward pressing connecting rod 8056 penetrates through the through seat 806. One end of the through seat 806 away from the penetration point is provided with a hinge seat. One ends of the intermediate connecting rod 8053 and the second long connecting rod 8054 are both arranged inside the hinge seat. The shape of the pressing block 807 matches the position where the cable groove is arranged in the switch 3.

[0041] In this embodiment, during the propulsion, since the transmission gear 801 meshes with the tooth part in the tooth limit group 6, the transmission gear 801 will rotate during the propulsion. The rotation of the transmission gear 801 is transmitted to the bevel gear set 803 through the transmission belt 802. The two sets of meshing gears in the bevel gear set 803 reverse the direction of the motion output. Then the rotation is transmitted to the short connecting rod 8051 to drive the overall motion of the articulated connecting rod 805, and then the downward pressure is output through the downward pressing connecting rod 8056. The size of the gear of the transmission gear 801 is not limited to this attached drawing and can be adjusted according to actual needs. The best state is to press the protrusion during the propulsion so that it enters the corresponding cable groove and then let the downward pressing connecting rod 8056 rise. The rise at this time has no influence on the insertion.

[0042] Please refer to Figure 8 、 10 and Figure 11 As shown in FIGS.

[0043] In this embodiment, the initial distances among the outer gear disc 902, the middle displacement triangular block 904, and the inner disc 905 are relatively large, which allows the cable head with protrusions to enter. After the cable head enters, the dial wheel group 901 can be appropriately twisted to reduce the distance. Then, when the cable is pulled backward, the cable head with protrusions cannot continue to retreat backward. After being resisted, the dial wheel group 901 can be rotated continuously, so that the dial wheel group 901 drives the worm and worm gear to rotate. Then the worm gear drives the outer gear disc 902 to rotate. The first group of outer gear discs 902 drives the small gear 903 to rotate, and the small gear 903 drives the second group of small gears 903 to rotate. Through this transmission, multiple groups of outer gear discs 902 rotate together, so that the cable is locked by the middle displacement triangular block 904 in the middle to achieve the purpose of preventing disconnection.

[0044] Specifically, the locking assembly 9 includes a toggle wheel set 901, and one side of the toggle wheel set 901 is meshed with an outer gear disk 902 through a worm gear, and the number of the outer gear disks 902 is multiple groups, and a transmission pinion 903 is meshed between the multiple groups of outer gear disks 902. A middle displacement triangle block 904 is provided on the rear side of the outer gear disk 902, and an inner disk 905 is provided on the rear side of the middle displacement triangle block 904. The outer gear disk 902 is located on the front side of the inner baffle 703, and the middle displacement triangle block 904 and the inner disk 905 are both located inside the inner baffle 703. A through hole is provided in the inner baffle 703 at a position corresponding to the cable groove of the switch 3.

[0045] In this embodiment, the worm gear combination is to prevent reversal. After the toggle wheel set 901 is rotated, the multiple sets of external gear plates 902 will not rotate in the absence of external force. The middle displacement triangle block 904 is composed of six sets of triangular structures that contact each other. After the front limit shaft 9041 and the rear slider 9042 are restricted front and back, the six sets of triangular structures will move laterally, and the gaps formed between them will expand and shrink, and the cables will be clamped using the reduced aperture.

[0046] Specifically, limiting grooves 9021 are arranged at equal intervals in the outer gear disk 902, a limiting shaft 9041 penetrating the limiting grooves 9021 is arranged on the front side of the middle displacement triangular block 904, a slider 9042 is arranged on the rear side of the middle displacement triangular block 904, and a hexagonal groove 9051 matching the slider 9042 is opened on the side of the inner disk 905 close to the slider 9042, a penetrating groove is arranged in the outer gear disk 902 and the inner disk 905, and a penetrating groove is formed in the middle position inside the middle displacement triangular block 904.

[0047] In this embodiment, the inner disc 905 and the middle displacement triangle block 904 are both arranged in the inner baffle plate 703. The number of the outer gear disc 902, the middle displacement triangle block 904 and the inner disc 905 arranged inside and outside the inner baffle plate 703 corresponds to the cable groove. The inner disc 905 is fixed in the inner baffle plate 703, and the middle displacement triangle block 904 moves in the inner baffle plate 703.

[0048] When in use, it is necessary to connect an external power supply, which provides power to the device so that the device can operate normally. First, the staff stands in front of the installation warehouse 1 and installs the first set of switches 3 at a position suitable for their own construction. First, connect the mounting plates 4 on both sides of the switch 3 with the nuts 207 at the appropriate positions, remove the nuts 207 originally at the ends of the connecting shaft 205, and then pass the tail end of the connecting shaft 205 through the connecting hole in the mounting plate 4, and then install the nut 207 from the inner side of the mounting plate 4 and tighten the threaded part of the connecting shaft 205, so that the switch 3 is positioned on one side of the chain lifting mechanism 2. When connecting the cable at the rear side of the switch 3, first enter the corresponding cable from the upper opening between the outer baffle 701 and the inner baffle 703, and pass through the inner baffle 703 and the outer gear plate 9. 02 into the inner side, and a row of cables are pulled backward after being passed through to the appropriate position. The locking assembly 9 can be used to lock the cable line, and the toggle wheel set 901 can be rotated. After the toggle wheel set 901 is rotated, the outer gear disc 902 is driven to rotate, and the small gear 903 between the outer gear discs 902 is driven to make multiple sets of outer gear discs 902 rotate in the same direction. When the outer gear disc 902 rotates, the limiting shaft 9041 inside it is driven to move, and the middle displacement triangle block 904 of the multiple sets of triangular structures moves together. The hexagonal hole formed between the sliders 9042 of the multiple sets of triangular structures is restricted by the rear slider 9042, which makes the hexagonal hole formed between the sliders 9042 of the multiple sets of triangular structures gradually shrink, and then the line of the cable passing through the middle is clamped and locked; After locking, the wire portion remaining on the outside of the inner baffle plate 703 can be passed through the wire-guiding block 702 to the outside of the hole at one end of the outer baffle plate 701, and then enter the tooth limit group 6, which is convenient for lifting and lowering to drive the cable to lift and lower together, and also convenient for connecting the cable end separately. Then, the quick-release assembly 7 can be pushed as a whole to one side of the switch 3, and the limit block in the inner baffle plate 703 and the limit groove in the switch 3 cooperate. When pushing forward, the transmission gear 801 will rotate due to the teeth in the meshing tooth limit group 6. The push gradually rotates, and the rotation action is transmitted to the bevel gear set 803 through the transmission belt 802, so that the bevel gear set 803 penetrates the fixed block 804 and drives the hinged connecting rod 805 to rotate. The rotation of the short connecting rod 8051 causes the pressing connecting rod 8056 to penetrate the inside of the seat 806 and then descend, thereby pressing the protrusion of the cable head through the pressing block 807, and inserting the cable head into the cable groove as it is pushed forward. Through the cooperation of the card and the component 705, the quick-release component 7 pushed to the bottom will be stuck and fixed on one side of the switch 3; After the connection is completed, the height of the installed switch 3 can be adjusted. Start the motor 201 so that the motor 201 drives the flower-shaped gear 203 to rotate through the pulley group 202. The rotation of the flower-shaped gear 203 will move the protruding connecting shaft 205 on one side of it, thereby causing multiple groups of front plates 204 and rear plates 206 to displace, driving the switch 3 to lift. Raise the switch 3, leaving a suitable operating position in front of the operator. Continue to install the next group of switches 3. After the installation is completed, continue to raise it until the first switch 3 is raised to the highest position.

[0049] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit, and the scope is defined by the appended claims and their equivalents.
