With reference to Fig. 7, Fig. 8 and Fig. 9, dead bolt 122b is inverted T-shaped structure, it comprises the dead bolt body b1 of cuboid bulk and affixed lock tongue supporting column b2 vertical with the upper surface of dead bolt body b1, and the both sides, front and back of the mounting groove 111 on Handheld Division 110 are provided with the lock tongue slot 111a identical with dead bolt 122b number, position is relative.In one embodiment, V-shaped slide rail a2 is provided with two, every bar V-shaped slide rail a2 is provided with two dead bolt 122b all symmetrically, has four dead bolt 122b, has four lock tongue slot 111a correspondingly.
Referring again to Fig. 7, Fig. 8 and Fig. 9, the front portion of dead bolt body b1 has the sloped contact surface b4 formed an angle with dead bolt body b1, the afterbody of dead bolt body b4 lacks one jiao thus forms the tapered plane b3 perpendicular to dead bolt body b1, the upper surface of dead bolt body b1, be provided with between tapered plane b3 with lock tongue supporting column b2 and parallel with tapered plane b3 and there is the straight guide groove b5 of certain distance, the front end of lock tongue supporting column b2 and dead bolt body b1 is provided with L-shaped lightening grooves b6, wherein, after dead bolt 122b indentation lock box 123, the front end of dead bolt 122b and the lateral surface of lock box 123 flush.Particularly, sloped contact surface b4 becomes 30 ° ~ 45 ° angles with the upper surface of dead bolt body b1, the width of described in-line slide rail equals the width of straight guide groove b5, and the distance between described in-line slide rail and V-shaped contact surface a4 equals the distance between straight guide groove b5 and tapered plane b3.In one embodiment, sloped contact surface b4 becomes 35 ° of angles with the upper surface of dead bolt body b1.
With reference to Figure 12, Figure 13, unlock shifting block 131 and comprise unblock push button 131a and driving member 131b, unlock push button 131a be integrally combined with driving member 131b thus make to unlock shifting block 131 structure in T shape, interlock shifting block 132 comprises sliding shoe and separates lock hook 132c, described sliding shoe is integrally connected with solution lock hook 132c thus makes described interlock shifting block 132 in in-line structure, the upper surface unlocking push button 131a is provided with L-shaped breach, the corner of described L-shaped breach is provided with the transition chamfering of arc-shaped, and the inner concave of described L-shaped breach is provided with anti-skidding striped.As a kind of embodiment, anti-skidding striped can be arranged to the striped be parallel to each other.
Referring again to Figure 12, Figure 13, the place bottom of driving member 131b is provided with link 131c, the left side of driving member 131b is provided with spring fixed column 131b ', this spring fixed column 131b ' is provided with and unlocks shifting block back-moving spring (slightly picture), be provided with sliding recess 132a to the front and back bilateral symmetry of described sliding shoe, make driving member 131b can level and smooth the moving back and forth in left and right in accommodating chamber, the upper surface of described sliding shoe is provided with draw-in groove 132b, unlock shifting block 131 by the link 131c of driving member 131b and the draw-in groove 132b place clamping of shifting block 132 at described sliding shoe that link, thus make user only just can promote unlock button 131a with a thumb, drive interlock shifting block 132 in accommodating chamber, to realize left and right toward polyslip simultaneously.The left side of described sliding shoe is provided with spring retainer post 132d, spring retainer post 132d is provided with interlock shifting block back-moving spring (slightly picture), the right side of described sliding shoe is integrally connected with separates lock hook 132c, separate lock hook 132c and form inverted T-shaped structure by drive block with taking off post, the described lefrward deletion taken off post a jiao is inclined-plane thus formation is stepped down, interlock shifting block 132 stirs groove a1 snapping by solution lock hook 132c's and plug body 122a, because the described lefrward deletion taken off post a jiao forms inclined-plane of stepping down, take off post described in making to be inserted into more expediently and stir in groove a1.
Operation principle: with reference to Figure 10 and Figure 11, first, after the sufficient electricity of power brick 120, before putting into mounting groove 111, as shown in figure 11, dead bolt 122b now stretches out the lockhole 123d of lock box 123, radially state for lock core 122 below power brick 120 and lock box 123 mated condition now, secondly, when power brick 120 being inserted into mounting groove 111, power brick 120 is placed in directly over mounting groove 111, then power brick 120 is pressed down in mounting groove 111, contact inclined-plane b4 on dead bolt 122b owing to being subject to one, mounting groove 111 frame reaction force upwards toward the inner indentation of lock box 123, when dead bolt 122b is retracted into when flushing outside lock box 123, power brick 120 can be depressed smoothly, can not stretch out because dead bolt 122b is subject to the restriction of mounting groove 111 side, until power brick 120 is pressed into the bottom of mounting groove 111, now dead bolt 122b arrives at lock tongue slot 111a place, owing to losing the restriction of mounting groove 111 side, and under the effect of back-moving spring, dead bolt 122b eject from snap close 123d thus with lock tongue slot 111a interlocking, and the ejection assembly 140 pressurized generation deformation bottom power brick 120, thus complete the installation process of power brick 120, finally, when power brick 120 electricity exhaust need again to charge time, drive interlock shifting block 132 by the unblock shifting block 131 stirring unlock switch assembly 130 thus impel plug body 122a along A arrow direction in Figure 10, dead bolt 122b is driven to be retracted in lock box 123 along the B direction of arrow in Figure 10, be subject to the effect of the restoring force of the ejection spring 142 ejecting assembly 140 bottom power brick 120 and eject, now just power brick 120 easily can be taken off.
Here the number of devices illustrated and treatment scale are used to simplify explanation of the present invention.Application of the present invention, modifications and variations be will be readily apparent to persons skilled in the art.
As mentioned above, according to the present invention, form because V-shaped slide rail a2 is connected by two angled in-line slide rails, described in-line slide rail stretches out plug body 122a and has certain distance, on plug body 122a, the concave surface opposite position of V-shaped slide rail a2 is provided with the V-shaped contact surface a4 matched with the concave surface of V-shaped slide rail a2, plug body 122a selectively can reciprocatingly slide in chute 123c, two dead bolt 122b are located on two described in-line slide rails respectively, each dead bolt 122b all selectively can reciprocatingly slide on respective described in-line slide rail, after dead bolt 122b indentation lock box 123, the front end of dead bolt 122b and the lateral surface of lock box 123 flush, thus make the slip that dead bolt 122b can be reciprocal back and forth on described in-line slide rail under the draw of plug body 122a, due to the special construction of V-shaped slide rail a2, dead bolt 122b while reciprocatingly sliding by lockhole 123d optionally extended or retracted lock box 123, thus achieve the process that just can lock or unlock power brick 120 by means of only a thumb promotion unblock push button 131a, enormously simplify the structure of locking mechanism, make again locking mechanism reliable and stable simultaneously.
Although embodiment of the present invention are open as above, but it is not limited in listed in description and embodiment utilization, it can be applied to various applicable the field of the invention completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the present invention is not limited to specific details and illustrates here and the legend described.
