[specific embodiment]
Below in conjunction with accompanying drawing and embodiment goods access blocking device is done further description.
Goods access blocking device like Fig. 1, Fig. 2 and an embodiment shown in Figure 3; Be used for depositing the goods (not shown) in freight house (not shown) and locking; And the unlock goods and the taking-up that will be locked in freight house, comprising: matching mechanism 10, push-pull mechanism 20 and the locking linkage 30 that is used to lock goods.Matching mechanism 10 is installed on the goods with locking linkage 30.
Matching mechanism 10 articulates with push-pull mechanism 20 with push-pull mechanism 20 mutual coupling realization matching mechanisms 10 and separates.
In the present embodiment, matching mechanism 10 is provided with groove 120 with push-pull mechanism 20 forward surfaces, and the sidewall of groove 120 is provided with three draw-in grooves 140, a pin 180 that is provided with a spring 160 in each draw-in groove 140 and slides in draw-in groove 140 through spring 160.In other embodiment, draw-in groove 140, spring 160 and sell 180 number and can be one, two, four or more.
In the present embodiment, push-pull mechanism 20 comprises: the adapter shaft 250, the axle collar 270 and the pull back spring 290 that are fixed on the fixed part 210 on the push-and-pull actuating unit (not shown), the auxiliary section 230 of matching with groove 120, captive joint fixed part 210 and auxiliary section 230.The axle collar 270 is set on the adapter shaft 250 with pull back spring 290, and pull back spring 290 is arranged between the axle collar 270 and the auxiliary section 230.
In the present embodiment, pin 180 is the inclined-plane with the forward surface of push-pull mechanism 20, to guarantee that pin 180 can be engaged portion 230 and clamp-on draw-in groove 140 smoothly with the axle collar 270, better blocks auxiliary section 230 simultaneously.
In the present embodiment, the working process of matching mechanism 10 and push-pull mechanism 20 is following:
When needs articulate matching mechanism 10 and push-pull mechanism 20; Auxiliary section 230 is stretched into and will be sold 180 in the groove 120 and be compressed into draw-in groove 160; And after pin 180 was passed in auxiliary section 230, pin 180 ejected and blocks auxiliary section 230, made push-pull mechanism 20 and matching mechanism 10 articulate.
When needs separate matching mechanism 10 with push-pull mechanism 20; Groove 120 is continued to stretch in auxiliary section 230, and the axle collar 270 contacts with pin 180 and will sell 180 tops in draw-in groove 140, and auxiliary section 230 continues to stretch into; The pin 180 the effect of spring 160 under the ejection and with the axle collar 270 butts after; Oppositely move auxiliary section 230, the axle collar 270 under the drive of pin 180 to auxiliary section 230 near, pull back spring 290 is compressed.The axle collar 270 is with after auxiliary section 230 contacts, and pin 180 surfaces that are connected along the axle collar 270 and auxiliary section 230 skid off, and push-pull mechanism 20 separates with matching mechanism 10.Meanwhile, compressed pull back spring 290 resets, and makes the axle collar 270 separate with auxiliary section 230.
In other embodiment, matching mechanism 10 can also adopt other structures with push-pull mechanism 20, as long as can realize articulating and separating of matching mechanism 10 and push-pull mechanism 20.
Locking linkage 30 comprises: drive link 310, lock link 320, the block 380 (consulting Fig. 4 and Fig. 5) that is arranged on locating dowel pin 330, lock link fixture block 340, baffle plate 350, baffle plate fixture block 360, the elastic component 370 on the lock link 320 and is fixed on the freight house inwall, the freight house inwall also is provided with the lock slots (not shown).
Drive link 310 is rotationally connected with matching mechanism 10.Lock link 320 1 ends and drive link 310 are rotationally connected, and the other end is a free end 324.
In the present embodiment, drive link 310 is hinged with matching mechanism 10, and lock link 320 is hinged with drive link 310, and elastic component 370 is a spring.
Lock link fixture block 340 is fixed on the path of motion that is used to limit lock link 320 on the goods, and locating dowel pin 330 is fixed on the lock link 320.When lock link 320 when lock link fixture block 340 moves, locating dowel pin 330 can block lock link fixture block 340, thus the stroke of restriction lock link 320.
Baffle plate fixture block 360 is fixed on the path of motion that is used for defining baffle 350 on the goods, and baffle plate 350 slides along baffle plate fixture block 360.Lock link 320 sense of motions are vertical with baffle plate 350 sense of motions.
Can find out that in conjunction with Fig. 4 and Fig. 5 baffle plate 350 is provided with the lock hole 352 that cooperates with lock link 320 free ends 324.
Elastic component 370 1 ends link to each other with baffle plate 350, and the other end links to each other with goods.
In the present embodiment, elastic component 370 is a spring.
Like Fig. 1 and shown in Figure 4, goods is in released state, and this moment, elastic component 370 was not stretched, and the free end 324 of lock link 320 supports on baffle plate 350, and this moment, lock link 320 can't move.
When needs lock goods; In conjunction with Fig. 2 and Fig. 5; Push-pull mechanism 20 promotes matching mechanism 10 makes goods move to the freight house direction; Be fixed on the freight house block 380 and baffle plate 350 butts and with baffle plate 350 to releasing away from the freight house direction, lock link 320 free ends 324 slip in the lock hole 352, this moment, elastic component 370 was stretched.Push-pull mechanism 20 continues to promote; Matching mechanism 10 drives drive link 310 and rotates; Thereby make lock link 320 move along lock link fixture block 340, lock link 320 free ends 324 pass lock hole 352 backs and extend in the lock slots, thereby goods is locked.
When the needs release; Push-pull mechanism 20 pulling matching mechanisms 10, matching mechanism 10 drives drive link 310 and rotates, thereby makes lock link 320 move along lock link fixture block 340; Lock slots and the lock hole 352 on the baffle plate 350 on the freight house regained and left to lock link 320 free ends 324; Accomplish the release of goods this moment, and goods is drawn out the elastic component 370 that is stretched in the process of freight house and resets, thereby makes baffle plate 350 reset.
This goods access blocking device comprises drive link 310 that is rotationally connected with matching mechanism 10 and the lock link 320 that is rotationally connected with drive link 310, slips into and skid off the locking and unlocking that the lock slots that is arranged on the freight house is accomplished goods through lock link 320 free ends 324.This goods access locking device structure is ingenious, cooperates precisely, and reliability is higher, thereby has a good application prospect.
The above embodiment has only expressed one embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with accompanying claims.
