Fig. 3 is the utility model two adjust bar gear mesh schematic representations in an embodiment.

As shown in Figures 1 and 2, the can that the utility model provides rises and covers device 1, comprises and holds member 10, venting hook component 30 and force application component 20 tightly.

Holding member 10 tightly comprises main body 107 and holds portion tightly, the portion of holding tightly comprises: the gear engagement of one end by is as shown in Figure 3 connected to two adjusts bar in main body 107 101, two first with the first rotating shaft 111 and holds body 108 and second tightly and hold the other end of 109, two adjusts bar 101 of body tightly and be separately installed with two first and hold body 108 tightly.Two first hold tightly body 108 for overbolt 102 and with overbolt 102 rubber coating 103 using that matches.Second hold tightly body 109 be two overbolts 105 and with overbolt 105 match use rubber coating 110.In main body 107, be equipped with can secured adjusted bar 101 secure component, secure component comprises tightening screw 106 and pad 104, presses by screwing tightening screw 106 pad 104 that is positioned at two adjust bar 101 tops, and adjust bar 101 is maintained static.

Venting hook component 30 comprises coupler body 301, torsion spring 304, chute 302 and slide block 303.Torsion spring 304 is arranged on coupler body 301 inside, and chute 302 is embedded on coupler body 301, and slide block 303 is positioned at chute 302 inside can be in chute 302 slips, and coupler body most advanced and sophisticated 305 is wedge shape.

Force application component 20 comprises application of force handle 201 and moves back hook handle 202, application of force handle 201 is connected with main body 107 by the second rotating shaft 112, coupler body 301 is fixedly connected with application of force handle 201 by torsion spring 304 and pivot pin 306, slide block 303 is connected with the one end of moving back hook handle 202, moving back hook handle 202 is rotatably connected by rotatable parts 203 and application of force handle 201, rotatable parts 203 comprise rotating connector 204, the 3rd rotating shaft 205 and rotating connector 206, coupler body 301, application of force handle 201, move back hook handle 202 and rotatable parts 203 and form a slider-crank mechanism, while moving back hook handle 202 along the 3rd rotating shaft 205 upward movement, band movable slider 303 slides in chute 302, can drive coupler body 301 to move simultaneously.

Second holds body 109 tightly between main body 107 and coupler body 301, and application of force handle 201 is structure as a whole, and two overbolts 105 are installed about 201 one-tenth rotational symmetry of application of force handle.

Fig. 4 be the utility model in an embodiment rotate by adjust bar the schematic diagram that obtains different radii circle.

As shown in Figure 4, two adjusts bar 101 are by regulating two the first distances of holding tightly between body 108, the radius that makes two overbolts 102 and rubber coating 103 and second hold the can ends holding circle that two overbolts 105 in

body

109 and 110 4 of rubber coatings surround tightly changes, to adapt to the needs of different big or small bottle caps 2.

Use the can that provides of the present embodiment to rise to cover device 1 to open bottle cap 2 and be divided into three processes, comprising: hold tightly with deflation course, move back hook process and the torsion process of outwarding winding.

(1) hold tightly and deflation course

Fig. 5 is the utility model process of holding tightly schematic diagram in an embodiment.

As shown in Figure 5, in the time that two adjusts bar 101 turn to certain angle along the first rotating shaft 111, two first rubber coatings 103 and second of holding tightly in body 108 are held two rubber coatings 110 in body 109 tightly and are close to bottle cap 2 and surround a can ends holding circle, after tightening screw 106 screws, pad 104 compresses two adjusts bar 101 maintains static adjust bar 101.

When application of force handle 201 rotates along the second rotating shaft 112, drive second to hold body 109 tightly along direction of arrow extruding as shown in Figure 5, make two first to hold body 108 tightly along direction of arrow extruding as shown in Figure 5 by the transmission of two adjusts bar 101, bottle cap 2 is held tightly.

Fig. 6 is the utility model venting equilibrium air pressure process schematic diagram in an embodiment.

As shown in Figure 6, in the time that application of force handle 201 continues to rotate along the second rotating shaft 112, drive coupler body 301 to move to body 3 directions, make coupler body tip 305 enter the gap between bottle cap 2 and body 3 by the elastic reaction of the inner torsion spring 304 of coupler body 301, after this,, in the time that application of force handle 201 upwards lifts gently, coupler body 301 and then rises, coupler body tip 305 prizes bottle cap 2, venting balance inner and outer air pressure.

(2) move back hook process

Fig. 7 is the utility model hook process of moving back schematic diagram in an embodiment.

As shown in Figure 7, when moving back the upwards application of force simultaneously when the application of force handle 201 downward application of force of hook handle 202, move back hook handle 202 with movable slider 303 in chute 302 along direction of arrow slip as shown in Figure 7, coupler body tip 305 is bound to the outside of bottle cap 2 simultaneously, completes and moves back hook.

(3) process is turned in rotation

Fig. 8 is that process schematic diagram is turned in the utility model rotation in an embodiment

As shown in Figure 8, in bottle cap 2 planes, centered by the center of circle of bottle cap 2, when the application of force handle 201 conter clockwise application of force, bottle cap 2 is outwarded winding.

The effect of embodiment and effect

The can providing according to the present embodiment rises and covers device, owing to being provided with two rotating adjusts bar, by changing two the first distances of holding tightly between body, make first to hold body and second tightly and hold the radius of four determined can ends holding circles of overbolt of body tightly and change, thereby can adapt to the needs of different big or small bottle caps.

In addition, due to a slider-crank mechanism being set, can exit safely and fast coupler body.

In addition, due to torsion spring being installed in coupler body, can make coupler body and jar cap fit tightly.

In addition, because the bolt sleeve using is rubber coating, can fit with jar cap preferably, hold bottle cap tightly.

In addition, the present embodiment can integratedly complete and hold jar cap tightly, the equilibrium air pressure of exitting, the bottle cap of outwarding winding, Safe withdrawing function.

Can provided by the utility model works the torsion spring that covers device can also replace with Compress Spring, extension spring, heterotypic spring, volute spiral spring, serpentine spring, jump ring, back-up ring, disk spring, spring leaf, steel spring etc.

Can provided by the utility model works the rubber coating that covers device and can also replace with other and have certain solidity and can produce the made bolt sleeve of the elastomeric material of larger friction force with metal.

Can provided by the utility model rises and covers second of device and hold body tightly and can also only contain an overbolt and bolt sleeve.

Certainly the related can of the utility model rises and covers device and be not merely defined in the structure in above-described embodiment.Above content is only the basic explanation under the utility model design, and any equivalent transformation of doing according to the technical solution of the utility model all should belong to protection domain of the present utility model.
