Abstract

The invention discloses a driving-wheel type bolt-pulling aid device, which aims to provide a practical bolt-pulling aid device with a simple structure, so that the bolt can be pulled up easily and safely. A complete set of the pulling aid device extends out a drive link from a panel of a power supply unit through a transmission shaft system in use, thereby jacking up the bolt. The device can avoid the possibility of electric shock when pulling up the bolt and the application of a transmission shaft structure enables a user to pull up the bolt in a more energy-saving and convenient mode at the same time.

Description

Transmission wheel type inserted pin pulling assistant device

Affiliated technical field

The present invention relates to a kind of inserted pin pulling assistant device, relate in particular to a kind of transmission wheel type inserted pin pulling assistant device.

Technical background

Current, supply units such as various embedded supply sockets, wiring board are widely used in the every aspect of producing, living.The method of supplying power to that present supply unit mainly adopts is a card edge type, it is characterized in that the latch of electricity consumption facility inserts i.e. energising (plug that is the electricity consumption facility directly inserts the interior loop that forms of the socket that has power supply), and the latch of electricity consumption facility is extracted i.e. outage.In order to guarantee that plug is difficult in use unartificially dropping or looseningly influence power supply safety, the method for generally taking to increase plug and socket contact portion frictional force drops and becomes flexible to prevent that plug is unartificial, reaches the purpose of assurance power supply safety.

But it is often very difficult when pulling the plug out of the socket thus.In the process of pulling the plug out of the socket, hand touches the plug metal part and divides the formation loop, tends to cause the generation of electric shock accidents, and this type of situation endangers especially obvious on one's body old man and children.

Summary of the invention

The present invention has overcome shortcoming of the prior art, a kind of transmission wheel type inserted pin pulling assistant device is provided, removed from staff for charged latch directly pull up action, thereby well avoided the generation of electric shock phenomenon.

In order to solve the technical problem of above-mentioned existence, technical scheme of the present invention is: at the inner cover transmission wheel type inserted pin pulling assistant device that adds of supply unit, link to each other with the insulation knob on being located at the supply unit panel, make staff not contact latch and finish the action that pulls up latch.The core component of package unit is by at least 1 rotatable fixture, at least 1 gear, a root fixed lever, at least 2 drive links (thrust drive link, active force drive link) and at least 1 button constitute (as Fig. 1) at least.

Operation principle of the present invention is: the press belt dynamicthrust drive link of being pushed on the supply unit panel by staff that button produced moves downward, rotate by the teeth driven gear on the thrust drive link, move upward by gear driven active force drive link again, thereby make the top of active force drive link stretch out supply unit, thereby reach purpose (as Fig. 1, Fig. 6) latch jack-up.

Vertically be placed under pin hole vertical perpendicular to the active force drive link of supply unit panel motion, the thrust drive link places under button vertical perpendicular to the supply unit panel, gear places between active force drive link and the thrust drive link, and the teeth structure on all parts all with the tight interlock of teeth structure (as Fig. 1) of corresponding part.

Realize that labor-saving structure can increase a bigger gear on basis of the present invention, making itself and original gear fix or two gears are integrated as Figure 10, Figure 11-1, Figure 11,2 can be so that the present invention realizes laborsaving design.

The feature of thrust drive link is: on thrust power transmission shaft and the one side that gear contacts the teeth structure is arranged, the thrust drive link can only be done perpendicular to the moving both vertically of supply unit panel, and the thrust drive link can be that individual components also can be combined as a whole with button.(as Fig. 4-1, Fig. 4-2)

The part drawing processing that the thrust power transmission shaft can be provided according to figure Fig. 4-1, Fig. 4-2 for the internal structure of adaptive supply unit also can be made amendment to its shape and size satisfying under the prerequisite of above-mentioned feature.

The feature of gear is: be fixed in supply unit inside, its teeth and thrust drive link and the mutual interlock of active force drive link.(as Fig. 2-1, Fig. 2-2)

The feature of fixed lever is: have 1 hole at least and fix with supply unit or with supply unit be one.(as Fig. 5-1, Fig. 5-2)

Gear and fixed lever can be two separate components, can also be by manually the two being assembled the all-in-one-piece assembly.

The feature of active force drive link is: on active force drive link and the one side that gear contacts the teeth structure is arranged, the supply unit panel can conveniently be stretched out, be return to active force drive link top shape, the active force drive link can only do perpendicular to the supply unit panel move both vertically.(as Fig. 3-1, Fig. 3-2)

The feature of rotatable jockey is: rotatable jockey can play fixing, interconnect function (as Fig. 1) between two parts.Rotatable jockey can be made by several different methods, as using the low density metals anchor or directly using technology such as screw and nut combination.

Above-mentioned use campaign for better constraint whole system can increase corresponding fixed part, as accessory under the prerequisite that does not influence the said elements feature.

In order to make a whole set of transmission wheel type inserted pin pulling assistant device can after use, automatically reply original position, can in package unit, add spring.It is characterized in that: spring in use can be made the transmission wheel type inserted pin pulling assistant device homing by the resilience force of self by the motion of above-mentioned transmission wheel type inserted pin pulling assistant device extruding when external force disappears;

The spring placement location can satisfy under the prerequisite of above-mentioned feature in conjunction with the real needs of inserting supply unit selected: as be placed on both sides or any side of gear, as Fig. 6, Fig. 7, Fig. 8, Fig. 9 in use spring be extruded, when external force disappears, can make package unit return initial position by the resilience force of self.Spring also can be fixed between button and the power supply, perhaps is arranged on the gear middle position.

Transmission wheel type inserted pin pulling assistant device is to be the separate component of one by at least 1 rotatable fixture, at least 1 gear, at least 1 fixed lever, at least 2 drive links and at least 1 button deep processing, can also be by manually each parts being assembled the all-in-one-piece assembly, can also be the assembly that is integrated with supply unit.

A kind of transmission wheel type inserted pin pulling assistant device can be by multiple material, make as metal, plastics, resin material, macromolecular material etc., wherein should be based on insulating material, button then must be by insulating material, manufacturing can be passed through kinds of processes, makes as methods such as mold pressing, machine work, injection mouldings.

Compared with prior art, the invention has the beneficial effects as follows: the first, be widely used, be applicable to various supply units, be specially adapted to wiring board, magazine socket, special-purpose active socket and the embedded attaching plug etc. of family expenses; The second, can guarantee safety, prevent to get an electric shock, especially be of value to old man, child's daily use; Three, material is easy to get, and technology is simple; Four, simple in structure, easy and simple to handle, the reliability height.
