Abstract
The utility model provides a frame opening-closing structure used for an electrically propelled wheelchair to get on and off a vehicle. The frame opening-closing structure comprises an upper pipe component (1) and a lower pipe component (2), a rotary shaft (3) capable of rotating is installed at one ends of the upper pipe component and the lower pipe component, a first connection component (4) which is used for being connected with a trunk of the electrically propelled wheelchair is installed on the upper pipe component, a second connection component (5) which is used for being connected with the bottom of a compartment is installed on the lower pipe component, and a handle (6), a lock component (7), a limiting device (8) and an upper pipe component check block (9) are installed on the lower pipe component. When the upper pipe component and the lower pipe component are folded, the upper pipe component is pushed to enable the limiting device to touch and push away the lock component, the lock component locks the upper pipe component by means of springback of a tensional spring, and a second lock piece bolt is inserted; and when the upper pipe component and the lower pipe component are unfolded, the bolt is pulled out, the handle is pulled to enable a push block of the lock component to push the upper pipe component check block, the upper pipe component is rotated along the rotary shaft, the handle is released so as to enable the lock component to return to an original position through resilience force of the tensional spring or through the handle, and a user can conveniently use the frame opening-closing structure.
Description
Technical field
This utility model relates to a kind of switching shelf structure, and particularly a kind of principle that two crossbeam one ends is fixedly connected with rotating shaft and rotates take rotating shaft as the axle center plays the band that makes things convenient for electric wheelchair to get on and off and opens and closes shelf structure.
Background technology
Need to take advantage of wheelchair-bound crowd for some, such as people with disability, old people, patient etc., they are when using electric wheelchair, when electric wheelchair needs getting on-off automobile or lorry, need the stranger to help or user oneself makes strength bring up to lorry etc., brought very large inconvenience to user.
The utility model content
It is inconvenient that the purpose of this utility model is to solve above-mentioned user of the prior art getting on-off automobile or lorry in using the electric wheelchair process, provides a kind of and two crossbeam one ends are fixedly connected with rotating shaft and rotation realizes the switching shelf structure that makes things convenient for electric wheelchair to get on or off the bus take rotating shaft as the axle center.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of switching shelf structure of getting on or off the bus for electric wheelchair, it comprises duct member, lower duct member, end at upper duct member and lower duct member is provided with rotatable rotating shaft, described upper duct member is provided with to be connected in the first link on the electric wheelchair boot, lower duct member is provided with the second link of connection body, and described lower duct member is provided with handle, locking member, stopping means, upper duct member block.
The beneficial effects of the utility model are: the second link that will be located on the lower duct member is connected with car body, the first link on the upper duct member is with after the boot that needs mobile electric wheelchair is connected, when the upper, lower tube parts close up, duct member makes stopping means on the pipe fitting of bottom bump the locking member on the duct member of staying and pushes open in the promotion, in the time of in advancing lower duct member fully, locking member carries out resilience by the power of torsion spring, and then duct member in the pinning inserts the second locking member latch feature; When the upper, lower tube parts need to separate, latch feature is pulled out, then spur handle component and make that the pushing block on the locking member is pushing away the block of going up on the duct member on the duct member, make duct member along take rotating shaft as the axle center rotating separation, then decontroling handle component makes locking member be returned to original position with the power of torsion spring resilience or directly with hands handle component is returned back to original position, so that people of user can get on and off electric wheelchair etc., and need not stranger's help.
As preferably, described stopping means is located at the top of locking member, described stopping means is limited block, when pulling handle and promote stopping means on duct member and the lower duct member, upper duct member does not allow directly to contact with transverse tube on the lower duct member when rotated, prevent surface damage, prolong its service life.
Further, be provided with resetting-mechanism between described locking member and the limited block.When duct member need to close up up and down, in the time of in upper duct member advances lower duct member fully, locking member carried out resilience, duct member in the pinning by the power of torsion spring; When the upper, lower tube parts will separate, decontrol handle component and make locking member be returned to original position with the power of torsion spring resilience or directly with hands handle component is returned back to original position.
Further, described resetting-mechanism is torsion spring.
Further, described rotating shaft is provided with axle sleeve, axle sleeve has been protected rotating shaft, reduced open and close frame close up and opening procedure in the wearing and tearing of duct member.
Further, described axle sleeve is steel bushing or copper sheathing.
