Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done concrete introduction.
Referring to figs. 1 through shown in Figure 4, at first the part that has general character among two embodiment is described, body rack 2 is that power tool body is extended for the accessory structure that power brick 1 is installed, power brick 1 can connect and compose an integral body by relative sliding with body rack 2, be power brick 1 can be on first direction A insertion machine body support frame 2, need to prove, body rack 2 should be formed with corresponding space and go to hold power brick 1, being slidingly connected between them, can realize by similar structures such as slide rails, but be not limited to this.Also be formed with lock hook 3 for locking in order to lock power brick 1, the concrete structure of lock hook 3 can be referring to Fig. 1 and Fig. 3, and lock hook 3 also can be that other can realize the hook structure that locks.
The utility model is in order to realize the utility model purpose, total design is as follows, be provided with one group of locked component, when hope is inserted in power brick 1, locked component can cooperate with the lock hook 3 of power brick 1, power brick 1 is locked in primary importance, in this process, the parts of being responsible in the locked component cooperating with lock hook 3 should be able to be dodged temporary transient lock hook 3, and then resilience realizes locking; In release, realize that this part when avoiding lock hook 3, can eject primary importance with power brick 1.
In order to realize above-mentioned design concept, locked component comprises: be connected with body rack 2 by self-position change to lock hook 3 realize lockings and release snap close piece 5, drive snap close piece 5 and have actuator to the position action of locking snap close piece 5, be used under the effect of external force, ordering about snap close piece 5 to the unlock piece of unlocked position action; Snap close piece 5 is formed with for moving the ejecting structure that ejects simultaneously power brick 1 to unlocked position; Power brick 1 is formed with for the roof construction for the treatment of for the ejecting structure contact.
As illustrated in figs. 1 and 2, in first embodiment, actuator itself can adopt magnetic force, the multiple recovery element such as elastic force is realized, in the present embodiment, actuator is for can make above-mentioned snap close piece 5 trend towards keeping snap close piece 5 at the elastic component 4 of the state of locking lock hook 3 when not being subjected to external force, particularly, in embodiment shown in Figure 1, elastic component 4 is a helical spring, snap close piece 5 is formed in being slidingly connected of second direction with body rack 2 so, by snap close piece 5 move back and forth realization the locking and unlocking, need to prove, second direction is different from above-mentioned first direction A.
See figures.1.and.2, snap close piece 5 is for practical function, and it is formed with for consisting of the fixed part 8 that be connected with being connected with actuator with the slide lock bonding part 7 of lock hook 3 contacts; Slide lock bonding part 7 is formed with the snap close inclined-plane 9 that tilts to intersect with first direction A.
Because it is mobile that snap close piece 5 can not produce at first direction A, so in order to eject power brick 1, power brick 1 shell forms skewback 10 conducts that eject that contact with it and treats roof construction when snap close piece 5 release, pass through skewback, realize the transmission of two vertical directions, accordingly, snap close piece 5 also is formed with for contacting the face that ejects 13 as ejecting structure with ejecting skewback 10, ejects face 13 and can be parallel to first direction A.
Wherein, fixed part 8 is fixedly connected with an end of elastic component 4, the other end of elastic component 4 is fixedly connected with body rack 2, so elastic component 4 has to the trend of the right side shifting of Fig. 1 snap close piece 5, order about snap close piece 5 and arrive its extreme position always left, this extreme position should be to lock the lock hook 3 that inserted, and when not inserting power brick 1, this also is the holding fix of snap close piece 5.As shown in Figure 1, when inserting power brick 1, the outside of lock hook 3 contacts with snap close inclined-plane 9, drive snap close piece 5 to the left side shifting of Fig. 1, elastic component 4 is compressed, along with further insertion, lock hook 3 can not withstand snap close piece 5 again, snap close piece 5 resiliences this moment, slide lock bonding part 7 just in time is stuck in the hook structure of lock hook 3, realizes locking; When the needs release, force snap close piece 5 to the left side shifting of Fig. 1 with external force, when lock hook 3 is withdrawed from slide lock bonding part 7, eject face 13 and eject skewback 10 and contact, eject gradually power brick 1, but when removing external force, snap close piece 5 recovers as before to the right under elastic component 4 effects.
For better operable lock fastener 5, need to be convenient to manual unlock piece and go to realize, they both can form respectively the part that also can be used as an integral body.In the embodiment shown in fig. 1, they are two independently parts, because snap close piece 5 is in body rack 2 inside, be difficult to touch, so as preferred, the pull-button of unlock piece for being slidingly connected with body rack 2, pull-button are formed with and are arranged on body rack 2 outsides for the manual button cap 11 of people and are arranged in the body rack 2 for contact the projection 12 that orders about its release with snap close piece 5.Button cap 11 can provide larger contact area during operation, and projection 12 can drive snap close piece 5 and move, and snap close piece 5 also should have the ledge structure that cooperates with projection 12 certainly.
With reference to Fig. 3 and shown in Figure 4, among the embodiment shown in Figure 3, snap close piece 5 and unlock piece on the functional meaning are made of same part, this part is called fit part 14, fit part 14 consists of being rotationally connected take third direction as axle with body rack 2, is an angle between third party and the above-mentioned first direction A.This is because fit part 14 is rotationally connected with body rack 2, thereby manual part and the part that ejects power brick 1 can be united two into one, partly expose body rack 2 as unlock piece during normality, can be operated, when withdrawing from power brick 1, this part is pressed to turn into body rack 2 inner realizations and ejects.
In the embodiment shown in fig. 3, with reference to shown in Figure 4, fit part 14 is formed with the locking cambered surface 15 that realizes snap close piece 5 functions and inserts inclined-plane 16, and lock hook 3 is formed with the hook cambered surface 17 that cooperates with locking cambered surface 15; The axis direction of locking cambered surface 15 is parallel with the rotor shaft direction of fit part 14, inserts inclined-plane 16 and tilts to intersect with first direction A.And, fit part 14 be formed with as ejecting structure pass through self be forced to rotate the button 18 that ejects power brick 1, flexible member is torsion spring, treats that roof construction is the shell shell wall of power brick 1.
As shown in Figure 3, the hook cambered surface 17 that fit part 14 pins lock hook 3 by locking cambered surface 15, because the effect of elastic component 4 torsion springs, when not inserting power brick 1, fit part 14 also is this state.If need release this moment, press button 18, fit part 14 rotates, locking cambered surface 15 produces to inserting inclined-plane 16, the insertion inclined-plane 16 of this moment is parallel with first direction A, not spacing to causing of lock hook 3, and the inboard of button 18 contacts with power brick 1 wall, continuation along with rotating can eject power brick 1.When inserting power brick 1, fit part 14 is identical with state shown in Figure 2, different is not yet plug-in mounting of power brick 1, inserting inclined-plane 16 this moment tilts to intersect with first direction A, therefore lock hook 3 contacts with it, can make fit part 14 by clockwise rotating among Fig. 3, when being inserted into to locking cambered surface 15 and 17 docking of hook cambered surface, fit part 14 is counterclockwise counter-rotating under the effect of torsion spring, realizes spacing on first direction A of power brick 1.
Above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in the protection range of the present utility model.
