Described sliding pin 85 is arranged in the described sliding tray 822 slidably and is positioned at the outside of described actuator 81, and the two ends of described sliding pin 85 contact at the front end of described actuator 81 and described holding section 31 respectively.By described sliding tray 822 is set, and described sliding pin 85 is set slidably in described sliding tray 822, when the described actuator 81 of pulling, the described sliding pin 85 of described actuator 81 pushing tows, described sliding pin 85 is outwards slided along described sliding tray 822, and the front end of the described holding section 31 of pushing tow, thereby trying hard to keep of guaranteeing that described actuator 81 applies is held in the horizontal direction with in the described rod member 50 of better pushing tow described holding section 31 retractions.
Shown in Figure 22 and 23, when release the lock rod member locking releasing mechanism 8, upwards lift described ribbon 60, described ribbon 60 drives described actuator 81 and upwards slides at described fixture 82, the section length of described actuator 81 between described the 3rd stop pin 83 and steady pin 821 shortens also and then the outside described sliding pin 85 of pushing tow, described sliding pin 85 is along the described sliding tray 822 outside also front ends of the described holding section 31 of pushing tow that slide, make the conflict of 31 disengagings of described holding section and described the 3rd stop pin 83 within the described rod member 50 of described fastener 30 retractions, finish release the lock.When needs lock again, described rod member 50 is turned to expanded position, the described sliding pin 85 of the lower surface pushing tow of holding section described in the rotation process 31 makes described sliding pin 85 slide into the inboard of described sliding tray 822, the described actuator 81 of described sliding pin 85 drives caves inward and increases the section length of described actuator 81 between described the 3rd stop pin 83 and steady pin 821, is conflicted by described the 3rd stop pin 83 and finish locking in described holding section 31.
Be depicted as the 5th embodiment of the present utility model as Figure 24 and 25, actuator described in the present embodiment 61, fastener 30, sticking department 70, the 3rd back-moving spring 65, guide finger 64, arranging of alignment pin 63 and ribbon 60 is all identical with the 3rd embodiment, therefore described element and numbering all can be with reference to Figure 14 to shown in Figure 19, difference is, described gathering sill 625 on the fixture described in the present embodiment 62 is substituted by a groove that vertically extends 627, the end that described actuator 61 does not arrange described pushing part is slidingly arranged in the described groove 627, and described groove 627 has two side 628.When the bottom of described pedestal 10 is subjected to power upwards or is in the bottom surface that projection is arranged, described rod member 50 can pivot downwards, thereby increase the strength that described holding section 31 contacts at described sticking department 70, this moment is if described pushing part 610 may cause distortion, the damage of described fastener 30 in the described holding section 31 of pushing tow by force.By described groove 627 and sidewall 628 are set, when above-mentioned situation takes place, described fixture 62 can rely on the sidewall 628 of described groove 627 to produce certain flexible deformation, when conflict in the surface of described sticking department and described holding section, two described sidewalls can be by the flexible deformation change close to each other and further distance to each other, reduce the strength that described holding section 31 contacts at described sticking department 70, for described fastener 30 provides certain release the lock space, make described pushing part 610 normally carry out release the lock in the described holding section 31 of pushing tow.
The utility model rod member locking releasing mechanism arranges described fixture, described fixture is fixed in the storage tank, and sticking department is installed on the described fixture, fastener is engaged with described sticking department, and then the locking of realization rod member, by described actuator is set, described actuator is installed on the described fixture slidably, utilize moving up and down and then driving described fastener and described lock section is separated from each other of actuator, thereby realize the release of rod member, simple in structure, whole process only need drive described actuator and get final product, easy to operate, described sticking department and fastener engaging have firmly effectively improved the stability of rod member locking releasing mechanism and the service life of product.
Above disclosed only is preferred embodiments of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of doing according to the utility model claim still belongs to the scope that the utility model is contained.
