Description

A kind of tire lifting apparatus

technical field:

The utility model relates to vehicle maintenance and repair accessory equipment field, particularly a kind of tire lifting apparatus.

background technology:

Existing family car is typically equipped with jack and helps car owner and overhaul or changing of tire vehicle, but need tire to be raised to certain altitude could tire is placed on wheel shaft owing to changing tire, therefore need by tire by manually praising when changing, this car owner especially women car owner is very difficult.

utility model content:

The purpose of this utility model is exactly the deficiency for prior art, and provides a kind of tire lifting apparatus, well solves the problem of car owner's changing of tire difficulty.

Technology solution of the present utility model is as follows:

A kind of tire lifting apparatus, comprise supporting component and clamp assemblies, supporting component comprises two long straight strut bars, strut bar midway location is spirally connected a locating piece, locating piece forms a through hole, the axial line of through hole is positioned on the line of centers of strut bar, 1 screw rod is socketed with in the through hole of locating piece, one end of screw rod is stretched out locating piece and is fixed on a bearing carrier ring, the other end of screw rod stretches out strut bar, one end that screw rod stretches out strut bar is bolted with crank, screw rod is also socketed with the slide block that 1 forms screw, slider bottom is also fixed with inserted block, one sidewall of inserted block forms socket, the bottom of inserted block is also bolted with 1 cardan wheel, the bottom of strut bar is also bolted with an inserted block away from one end of crank, the bottom of inserted block is also bolted with a cardan wheel, clamp assemblies comprises 2 inserted links, one end of inserted link is agreed with mutually with socket, the bottom of the other end of inserted link is also bolted with cardan wheel.So just can in use inserted link be inserted in inserted block, and will the tire changed be needed to be placed between two inserted links, rotate crank again, make bolt rotary, thus band movable slider moves towards locating piece, spacing between 2 inserted links is just diminished gradually, so just the tire between 2 inserted links can be erected by inserted link, easily achieve tire lifting and be stabilized in the object of certain altitude, greatly facilitate car owner, the utility model volume is also little, only needs inserted link to unload when not using, and just can put into the boot of vehicle easily.

As preferably, also include push rod, push rod has 2, and wherein one end of 2 push rods is articulated with the two ends of 2 sidewalls of strut bar respectively, and the other end of 2 push rods is all hinged with a handles.So just in use push rod can be dug, and overturn handle, make push rod and bracing frame form the shape of a go-cart, thus will the tire changed be needed to carry out displacement easily.

As preferably, the length of push rod is less than the length of strut bar.So just can when not using, the utility model be folded up and not increase volume, be applicable to all types of family expenses vehicles.

As preferably, locating piece is positioned in the middle part of strut bar.So just limit the spacing between 2 push rods, because tire rising height depends on the spacing between push rod, spacing between restriction push rod, and the more high easier overturning of tire lifting, locating piece is arranged in the middle part of strut bar and tire rising height can be made to fix, and avoids maloperation to cause tire overturning.

As preferably, crank is fixed on a gear case, and screw rod sleeve is in the rotating shaft of gear case.The crank be rotatably installed in like this on gear case just can utilize gear case to reach labour-saving object, and uneasy toothing roller box directly otherwise connects on crank and also belongs to this patent scope.

The beneficial effects of the utility model are:

Inserted link can insert in inserted block by the utility model in use, and will the tire changed be needed to be placed between two inserted links, rotate crank again, make bolt rotary, thus band movable slider moves towards locating piece, spacing between 2 inserted links is just diminished gradually, so just the tire between 2 inserted links can be erected by inserted link, easily achieve tire lifting and be stabilized in the object of certain altitude, greatly facilitate car owner, the utility model volume is also little, only needs inserted link to unload when not using, and just can put into the boot of vehicle easily.

accompanying drawing illustrates:

Fig. 1 is structural representation of the present utility model;

In figure: strut bar 1; Locating piece 2; Screw rod 3; Bearing carrier ring 4; Crank 5; Slide block 6; Inserted block 7; Cardan wheel 8; Inserted link 9; Push rod 10; Handle 11; Gear case 12.

detailed description of the invention:

Embodiment: a kind of tire lifting apparatus as shown in Figure 1, comprise supporting component and clamp assemblies, supporting component comprises two long straight strut bars 1, strut bar 1 midway location is spirally connected a locating piece 2, locating piece 2 forms a through hole, the axial line of through hole is positioned on the line of centers of two strut bars 1 compositions, 1 screw rod 3 is socketed with in the through hole of locating piece 2, one end of screw rod 3 is stretched out locating piece 2 and is fixed on a bearing carrier ring 4, the other end of screw rod 3 stretches out strut bar 1, one end that screw rod 3 stretches out strut bar 1 is bolted with crank 5, and insert the gear case 12 be made up of a gear pair, the crank 5 be rotatably installed on gear case 12 just can utilize gear pair to reach labour-saving object, screw rod 3 is also socketed with the slide block 6 that 1 forms screw, inserted block 7 is also welded with bottom slide block 6, one sidewall of inserted block 7 forms socket, the bottom of inserted block 7 is also bolted with 1 cardan wheel 8, the bottom of strut bar 1 is also bolted with an inserted block 7 away from one end of crank 5, the bottom of inserted block 7 is also bolted with a cardan wheel 8.Clamp assemblies comprises 2 inserted links 9, and one end of inserted link 9 is agreed with mutually with socket, and the bottom of the other end of inserted link 9 is also bolted with cardan wheel 8.
