Technical field
The present invention relates to auto parts and components, more particularly to a kind of self-locking type spare wheel carrier.
Background technique
Currently, existing spare tyre locks on vehicle frame or vehicle body generally by chain, supporting plate, elevating endless screw, but
It is during vehicle driving, because of shake, the factor of gravity, elevating endless screw easily inverts and causes chain-loose, and spare tyre is lost, can
Poor by property, the especially spare tyre of cargo vehicle, spare tyre is bulky, and gravity is larger, encounters the bad place of road conditions, goes up and down
Worm screw cannot be in self-locking state constantly, easily loosen.
Summary of the invention
The purpose of the present invention is to provide a kind of self-locking type spare wheel carriers, can be self-locking to elevating endless screw realization, avoid lifting snail
Bar reversion, improves the fastening reliability of product.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals:
Self-locking type spare wheel carrier, including chain, the supporting plate being connect with chain, shell, be arranged at the intracorporal irreversible worm of shell,
Self-locking mechanism, worm gear assembly, the elevating endless screw connecting with worm gear assembly, chain are wound around on worm gear assembly, irreversible worm, worm gear
Assembly, elevating endless screw connect with housing into rotation, and self-locking mechanism includes the bar that sticks up connecting with housing into rotation, irreversible worm and lifting
Worm screw is arranged side by side, and sticks up bar one end and connect with irreversible worm, sticks up the bar other end and connect with worm gear assembly.
Preferably, sticking up bar includes the claw portion cooperated with the ratchet clamping part of the spiral tooth engagement of irreversible worm and teeth portion, card
Teeth portion is an integral structure with claw portion.
Preferably, relative tilt is arranged between ratchet clamping part and claw portion.
Preferably, self-locking mechanism further includes the bracket being immobilized in the shell, sticks up and be located at ratchet clamping part and claw portion on bar
Joint is hinged with bracket.
Preferably, the ratchet clamping part for sticking up bar heads on the helical tooth on irreversible worm, the claw portion for sticking up bar heads on worm gear assembly
On tooth.
Preferably, irreversible worm is equipped with self-locking connector, it is exposed outside shell that self-locking connector is pierced by shell.
Preferably, elevating endless screw is equipped with lifting connector, it is exposed outside shell that lifting connector is pierced by shell.
Preferably, having the drum for winding chain, the tooth with the spiral tooth engagement of elevating endless screw on worm gear assembly
Portion.
The present invention has significant technical effect: when installation spare tyre, spare tyre being placed due to using above technical scheme
On supporting plate, elevating endless screw is rotated afterwards, and chain rising drives spare tyre to move up and withstands vehicle frame or vehicle body, screwing irreversible worm, making
It sticks up bar and withstands worm gear assembly, self-locking is played to elevating endless screw, the elevating endless screw moment is in self-locking state, can prevent vehicle row
Spare tyre loosens under the action of by gravity or shake during sailing, more structurally sound to consolidate spare tyre, and convenient disassembly,
Reliably.When needing to remove spare tyre, irreversible worm is first unclamped, irreversible worm drives the ratchet clamping part for sticking up bar along the spiral shell of irreversible worm
Tooth rotation is revolved, is driven with the claw portion of ratchet clamping part integral structure by ratchet clamping part, leaves the teeth portion of worm gear assembly, unclamp again lifting
Worm screw, chain can decline, and drive supporting plate decline, remove spare tyre.
Detailed description of the invention

The toponym that each number designation is referred in attached drawing is as follows: wherein 1-chain, 2-shells, 3-irreversible worms,
4-worm gear assemblies, 5-elevating endless screws, 6-drums, 7-teeth portion, 8-balls, 9-lifting connectors, 10-self-locking connectors,
Bar, 13-helical tooths, 14-ratchet clamping parts, 15-claw portions, 16-pin shafts are stuck up in 11-brackets, 12-.
Specific embodiment
Present invention is further described in detail with embodiment with reference to the accompanying drawing.
Embodiment
Self-locking type spare wheel carrier, as shown in Figure 1, including chain 1, the supporting plate connecting with chain 1, shell 2, being arranged at shell
Irreversible worm 3, self-locking mechanism, worm gear assembly 4 in 2, the elevating endless screw 5 with the rotation connection of 4 worm gear of worm gear assembly.
The teeth portion 7 that there is the drum 6 for winding chain 1 on worm gear assembly 4, engaged with the helical tooth 13 of elevating endless screw 5,
Worm gear assembly 4 is rotatably connected by ball 8 or bearing with shell 2.Elevating endless screw 5 can be turned by ball 8 or bearing with shell 2
Dynamic connection.Irreversible worm 3 is rotatably connected by ball 8 or bearing with shell 2.In the present embodiment, worm gear assembly 4, lifting
Worm screw 5, irreversible worm 3 are rotatably connected by ball 8 with shell 2.Elevating endless screw 5 and irreversible worm 3 are disposed side by side on shell
In body 2, elevating endless screw 5 is equipped with lifting connector 9, lifting connector 9 is pierced by shell 2 exposed outside shell 2, irreversible worm 3
It is equipped with self-locking connector 10, it is exposed outside shell 2 that self-locking connector 10 is pierced by shell 2.
Self-locking mechanism is arranged between elevating endless screw 5 and irreversible worm 3, and self-locking mechanism includes being fixed in shell 2
Bracket 11, with bracket 11 be rotatablely connected stick up bar 12, sticking up bar 12 includes the ratchet clamping part engaged with the helical tooth 13 of irreversible worm 3
14, the claw portion 15 cooperated with teeth portion 7, ratchet clamping part 14 is an integral structure with claw portion 15, ratchet clamping part 14 and claw portion 15 it
Between relative tilt be arranged, stick up the joint for being located at ratchet clamping part 14 and claw portion 15 on bar 12 and bracket 11 be hinged by pin shaft 16,
It sticks up bar 12 and connection is relatively rotated by bracket 11 and shell 2, so that sticking up the structure that bar 12 forms a similar lever, fulcrum is
