Detailed description of the invention

Below in conjunction with specification drawings and specific embodiments, this utility model is further illustrated.

As shown in Figure 1, 2, this utility model includes table top 1, hold down gag 2, automatic wire winding device 3.

Described table top 1, including installing plate 11, locking device 12, described installing plate 11 has through hole, and table top 1 has square hole, and supplied for electronic product input cable enters.Described locking device 12 includes lock body and dead bolt, its concrete structure can be that springlock can also be for electronic lock, as long as can realize when locking, dead bolt stretches out, the function that when opening, dead bolt is regained, the concrete structure of lock body and dead bolt is prior art, has multiple implementation, and therefore concrete structure is not repeated herein

Described hold down gag 2, as shown in Figure 3, including bolt and nut pair 21, torsion spring 22 and pressing plate, described pressing plate is L-shaped, and galianconism end has inclined-plane towards long-armed direction, form wedge shape, and on galianconism, having square hole, described square hole adapts with the dead bolt size of locking device 12, and long-armed end is hinged with installing plate 11 by bolt and nut pair 21, torsion spring 22 is coaxially socketed with bolt and nut pair 21, relies on the seif-citing rate of torsion spring 22 can realize opening of hold down gag 2.

Described automatic wire winding device 3, as shown in Figure 4,5, including installing rack 31, rotary shaft 32, permanent magnet 33, electric magnet 34, micro machine 35, power supply 36, press button 37, described installing rack 31 includes installation seat plate, vertical plates on both sides and outer housing, have through hole in installation seat plate, vertical plates on both sides, use screw to be connected by the lower plane of installing rack 31 with table top 1 by through hole on installation seat plate.Described permanent magnet 33, electric magnet 34 are annular and polarity is consistent, it is concentrically mounted on riser inwall with the through hole in installing rack 31 vertical plates on both sides, the most as shown in the figure, permanent magnet 33 and electric magnet 34 are separately mounted on two riser inwalls, described micro machine 35, power supply 36, press button 37 are installed on installing rack 31 1 cant board outer wall, the position of press button 37 adapts with hold down gag 2 galianconism end wedge shape, namely when hold down gag 2 galianconism moves down, press button 37 is depressed at any time.

Described press button 37 is connected with power supply 36 circuit, and press button 37 is used for open circuit or the path in control circuit loop.Described power supply 36 is connected with micro machine 35 circuit, includes intervalometer, namely micro machine 35 starts after power supply 36 starts power supply, and micro machine 35 is automatically switched off after reaching the time that intervalometer sets in described micro machine 35 control circuit.Include intervalometer in structure, and the micro machine that functionally can complete regularly to cut out after operation sets the time is multiple as prior art, its internal structure and circuit implementations, is not repeated at this.Described power supply 36 is also connected with electric magnet 34 circuit, and during circuit loop path, electric magnet 34 produces electro permanent magnetic.

Described rotary shaft 32, including main shaft 321, clamping boss 322, winding roll 323, described main shaft 321 two ends are erected on the through hole of installing rack 31 vertical plates on both sides, and one end is boss, diameter is more than corresponding through-hole diameter, and the other end is threadeded with the armature spindle of micro machine 35；Described clamping boss 322 is connected with main shaft 321 by holding screw, is provided with a tight boss of cant board proximity card 322 of described permanent magnet 33.Described winding roll 323 includes two ends shrouding and cylindrical central sleeve, draw-in groove corresponding with clamping boss 322 it is provided with in cylindrical central sleeve, draw-in groove size is more than clamping boss 322 size, permanent magnet respectively it is embedded with outside two ends shrouding, position adapts with the permanent magnet 33 in installing rack 31 vertical plates on both sides, electric magnet 34, and its polarity and permanent magnet 33 in installing rack 31 vertical plates on both sides, electric magnet 34 are identical.The magnetic force of described electric magnet 34 is more than the magnetic force of each permanent magnet.When electric magnet 34 obtains electric, its magnetic force is more than the magnetic force of each permanent magnet, the same sex is repelled each other, winding roll 323 moves to clamping boss 322 direction, and the size of clamping boss 322 and with the size difference of draw-in groove ensure that electric magnet 34 electric time, clamping boss 322 plugs together with draw-in groove, enables the two to rotate simultaneously.

Implementation is as follows: after the locking device 12 on table top 1 is unlocked, its dead bolt exits from hold down gag 2 square hole, now under the effect of torsion spring 22, hold down gag 2 opens up, compacted electronic product can take out smoothly, simultaneously, hold down gag 2 departs from press button 37, circuit loop is off state, micro machine 35, electric magnet 34 dead electricity is out of service, under the effect that the permanent magnet being embedded with at termination, winding roll 323 side shrouding and the permanent magnet 33 on installing rack 31 1 cant board inwall produce repulsion, the draw-in groove of winding roll 323 cylindrical central sleeve plugs together with clamping boss 322 disengaging, winding roll 323 is on the smooth axial plane of main shaft 321, under the drag interaction of outside electronic product, its corresponding cable can freely extend；nullWhen electronic product is placed on the playing surface 1，The galianconism of hold down gag 2 is inserted in table top 1 upper aperture，Locking locking device 12，Dead bolt inserts square hole，Under the effect of hold down gag 2 galianconism terminal slope，Press button 37 is depressed，Circuit loop is channel status，Micro machine 35、Electric magnet 34 obtains electric bringing into operation，Under energization action，Electric magnet 34 produces magnetic field，And the permanent magnet of side corresponding with winding roll 323 embedding produces repulsion，The repulsion produced due to electric magnet 34 side is more than the repulsion that two corresponding permanent magnets of other side produce，Winding roll 323 is pushed to the side near clamping boss 322，And finally realize plugging together of winding roll 323 and both clamping boss 322，Obtaining electric micro machine 35 drives rotary shaft 32 to rotate，And then drive winding roll 323 to rotate，Thus realize automatic winding function.

It should be noted that; this utility model has been described in detail by particular of the present utility model; for a person skilled in the art, the various obvious change carried out it in the case of without departing substantially from spirit and scope of the present utility model is all within protection domain of the present utility model.
