Detailed Description

Example 1: as shown in fig. 1-4, a mobile phone collecting device comprises a positioning pulley 2, a bearing bracket 11, a winding shaft 12, a handle 13, a hanging box 14 and a balance bar 15; the positioning pulley 2 is fixed on the ceiling 1, the bearing frames 11 are fixed on the wall 6, one of two equal-length steel wire ropes is connected with one end of the hanging box 14 and then bypasses one set of positioning pulley 2 to be connected with one end of the balancing rod 15, the other steel wire rope is connected with the other end of the hanging box 14 and then bypasses the other set of positioning pulley 2 to be connected with the other end of the balancing rod 15, the winding shaft 12 is positioned by bearings in the two bearing frames 11, the steel wire rope wound on the winding shaft 12 between the two bearing frames 11 is connected with the middle part of the balancing rod 15, and one end of the winding shaft 12 is connected with the.

The inner diameter of the fixed shaft sleeve 8 is slightly larger than the outer diameter of the part connected with the winding shaft 12 by 1mm-2mm, and the winding shaft 12 can be separated from the restriction of the motor 7 by unscrewing the fixed screw 9, so that the resistance required to be overcome when the handle 13 is used for controlling the lifting of the hanging box 14 is reduced.

The transverse and longitudinal distances between the positioning pulleys 2 and the length of the balancing rod 15 can be adjusted according to specific conditions.

The hanging box 14 and the balance rod 15 are made of aluminum alloy materials, and the weight of the structure is reduced under the condition that the structural strength is guaranteed.

The hanging box 14 is about 1.2 meters away from the ground when the mobile phone is stored and taken out, and about 2.2 meters away from the ground at other times.

The utility model discloses the use does:

this application can adopt manual control, also can motor control:

if only the manual control part is installed, the manual control is that the handle 13 drives the winding shaft 12 to rotate, the steel wire rope is driven to move, and the lifting of the hanging box 14 is controlled.

If the manual and motor control parts are installed, the manual control and the motor control can be realized:

under the normal power-on condition, can manual control, also can motor control, motor control is as follows: the magnet 3 is mainly connected with a power supply of a driving motor 7, the self-locking piece 4 is adsorbed at the bottom of the electromagnet 3, the motor 7 drives a winding shaft 12 connected by a fixed shaft sleeve 8 and a fixed screw 9 (the fixed shaft sleeve 8 and the fixed screw 9 act as a clutch, but the manufacturing cost is far lower than that of the clutch) to rotate, a steel wire rope is connected between the winding shaft 12 and a balance rod 15, one end of the steel wire rope is fixed on the winding shaft 12 between two bearings, and the other end of the steel wire rope is fixed at the center of the balance rod 15, so that the rotation of the winding shaft 12 drives the steel wire rope, the balance rod 15 and a hanging box 14 to move, when the hanging box 14 descends to a required position, the steel wire rope can be used for placing a mobile phone, when the hanging box 14 ascends, the mobile phone is used for storing the placed. Or manually, the fixing screw 9 is unscrewed to eliminate the resistance generated by the control of the motor 7, and then the winding shaft 12 is driven to rotate by rotating the handle 13 to drive the steel wire rope to move, so as to control the lifting of the hanging box 14.

Under the normal power-on condition, the motor 7 has a self-locking function and does not need to be additionally provided with a self-locking device; under the condition of sudden power failure, the self-locking piece 4 falls down instantly due to loss of magnetic force, the stop lever with one end clamped in the self-locking piece support 5 limits self rotation (one end of the self-locking piece 4 is provided with a transverse through hole for being sleeved with the stop lever of the self-locking piece support 5, two ends of the stop lever are fixed through nuts, the self-locking piece 4 can rotate around the self-locking piece support 5, the other end of the self-locking piece is a free end), and the other end clamps the ratchet of the ratchet wheel 10 to prevent the winding shaft 12 from rotating.

In case of power failure, manual control is performed: the self-locking plate 4 may cause inconvenience in lifting the paper hanging box 14, and since the rated voltage of the electromagnet 3 is only 24V, the electromagnet 3 may be equipped with a standby power supply in order to facilitate manual lifting of the paper hanging box 14, but the standby power supply of the electromagnet 3 is normally in a closed state. In the case of a power failure, the fixing screw 9 is unscrewed to eliminate the resistance due to the control of the motor 7. Then, the standby power supply of the electromagnet 3 is turned on, the handle 13 is shaken to lift the self-locking plate 4 to enable the self-locking plate to be adsorbed below the electromagnet 3 again, so that the handle 13 can conveniently drive the winding shaft 12 to rotate, the steel wire rope is driven to move, and the lifting of the hanging box 14 is controlled. After the operation of storing and taking the mobile phone is finished, the standby power supply of the electromagnet 3 is turned off, so that the self-locking piece 4 falls down to continuously play a self-locking protection role.

For most scenarios, one can set: when the mobile phone is stored and taken, the hanging box 3 is dropped to a position 1.2 meters away from the ground, and after the mobile phone is stored and taken, the hanging box 3 is lifted to a position 2.2 meters away from the ground. The lifting of the hanging box 14 is controlled by a single-pole double-throw timing switch independently arranged in each room, and the model of the single-pole double-throw timing switch is QJCS-63, so that the hanging box 14 can be safely and accurately lifted to a set position. The positive and negative rotation can be realized by the positive and negative connection of the zero line and the live line of the motor 7, so that the positive and negative rotation of the motor 7 can be realized by only one single-pole double-throw switch, and the hanging box 14 is further controlled. However, in order to prevent the wire rope from being broken due to the excessively long rotation time of the motor 7, the switch needs to have a timing characteristic, and the timing switch only needs to be set for one time, if the angular speed of the motor is x, the radius of the winding part of the winding shaft 12 is y, and the movement distance of the hanging box 14 is 1 meter each time (which can be adjusted according to specific situations, and the single wire rope for connecting the hanging box and the balance bar together needs to be in accordance with the movement distance of the hanging box), the timing time of the timing switch is t = 1/(x y). After the timing time of the timing switch is set, the safe lifting of the hanging box 14 can be realized only by operating the switch bidirectional control part.

While the present invention has been described in detail with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
