Abstract
A ladder truck is characterized in that a frame, a handle 16 and a spring rod 11 are arranged on a transmission frame 3, wheel shafts are connected with a left transmission frame, a right transmission frame and a main wheel 5, the spring rod, a short connecting rod and a long connecting rod are hinged with each other, a sliding groove 15 is formed in the transmission frame, a top rod 4, a spring and other parts are arranged in the transmission frame and matched with a ratchet wheel and a pawl, and under the driving of the connecting rod, a catch wheel, the main wheel, an auxiliary wheel and other parts, the labor-saving ladder can be pushed and pushed on the ground, the walking is stable and continuous, no impact force exists, the noise is.
Description
The utility model relates to family's smaller vehicle, particularly a kind of cat ladder car.
Once the three-wheel of Chu Xianing, five was taken turns the cat ladder car, mostly was to be starriness on the same axle and to arrange a plurality of car wheel structures designs.The cat ladder inequality is held in the mouth, stationarity is poor, impulsive force is big.
The purpose of this utility model provides a kind of walking and cat ladder is steady, continuous and labour-saving cat ladder car.
Described cat ladder car comprises wheel, vehicle frame each several part, it is characterized in that: described vehicle frame and handle 16, spring bar 11 are contained on the gear frame 3, two gear frames 3 and main wheel 5 about axletree 9 connects; One end of short connecting rod 12 is hinged in the middle of long connecting rod 14, and ratchet 7 is housed on the other end; Be equipped with on the ratchet 1 as the torsion spring 2 of pushing down ratchet; Have a gear frame sliding tray 15 perpendicular to gear frame 3 directions, axletree 9 places in it, is pressed with on the axletree on the compression push rod 4,4 and is with auxiliary spring 8; Gear frame 3 vertically rises a strip slot, and the end that compression spring 10,10 is housed in the groove is connected with spring bar 11, and the other end of spring bar and long connecting rod 14 and gear wheel 13 are hinged; The other end of long connecting rod 14 then is hinged with accessory whorl 6; Gear wheel 13 can drive spring bar 11, compression spring 10, long connecting rod 14, short connecting rod 12 and ratchet 1 gear shaft on gear frame 3 and rotate.
The utility model has adopted connecting rod, spring, floating axle, ratchet combination mechanism, has realized laborsaving cat ladder, smooth running, continuously, and no impulsive force, noise are little, delicate structure, be suitable for family expenses.
Fig. 1 is the utility model appearance structure scheme drawing.
Fig. 2 is the utility model drive mechanism scheme drawing.
Fig. 3 is the utility model cat ladder status architecture scheme drawing.
Among the figure: 1-ratchet, 2-torsion spring, 3-gear frame, 4-push rod, 5-main wheel, 6-accessory whorl, the 7-ratchet, 8-auxiliary spring, 9-axletree, 10-compression spring, 11-spring bar, the 12-short connecting rod, 13-gear wheel, 14-long connecting rod, 15-gear frame sliding tray, 16-vehicle frame and handle.
The implementation process:
When main wheel 5 contacted with ground A, axletree 9 was in the upper extreme point of the sliding tray 15 of gear frame 3, and auxiliary spring 8 is compressed, push rod 4 rises, the ratchet 1 that jack-up 3 is pushed down by torsion spring 2, and ratchet 1 separates with ratchet 7, compression spring 10 flicks, and main wheel can be in ground surface.
During cat ladder, gear wheel 13 contacts with step surface B, continue to pull a cart, gear wheel 13 drives spring bar 11 and compression spring 10 retreats, the gear shaft of ratchet 7 on gear frame 3 that simultaneously also drives long connecting rod 14 and short connecting rod 12 and be fixed on the short connecting rod clockwise rotates, the accessory whorl 6 on the long connecting rod increased gradually and main wheel 5 between centre distance, when gear wheel is in position among Fig. 3, main wheel 5 contacts with step C face, just as than having gone up step C face reposefully.In the cat ladder process, main wheel does not bear gravity.Auxiliary spring 8 flicks, and depresses push rod 4 and axletree, and torsion spring 2 is pushed down ratchet, and ratchet inserts ratchet 7 (Fig. 3 shows) downwards.Ratchet on the short connecting rod can only unidirectional rotation, and compression spring is compressed and can not flicks, and the accessory whorl on the long connecting rod bears weight and rolls at step surface.When the C face step in the main wheel hookup 3, main wheel is stressed, and the jack-up auxiliary spring is got back to incipient state (Fig. 2 shows state), continues the cat ladder of next step.
