Description

A kind of Anti-theft spare wheel carrier of vehicle connecting rod structure

Technical field

This utility model is the improvement to automobile spare tire carrier structure.

Background technology

Existing automobile spare tire is fixed on body bottom section by fixed plate, during use, rotates connecting rod, manually calabash makes It declines, you can using spare tyre.Connecting rod structure is that the end section stretched out outside vehicle body is hexagon, during use, can pass through six Angle spanner is rotatably connected bar.But the shortcoming of this structure is, anyone can be rotatably connected bar by spanner, and automobile easily occurs Spare tyre is lost.

Content of the invention

This utility model is the shortcoming overcoming above-mentioned prior art to exist, and provides a kind of improved Anti-theft spare wheel carrier of vehicle.

A kind of Anti-theft spare wheel carrier of vehicle connecting rod structure passes through jump ring with hexagonal part even it is characterised in that connecting boom end Connect；

Hexagonal part internal upper part is provided with lock；Many ribs hole is set in the middle part of hexagonal part, and bottom is connected with connecting rod；

Lock is made up of with lock core lock core shell；Lock core is rotated with lock core shell and is connected；Lock core shell passes through jump ring and hexagonal Part connects, axial restraint hexagonal part；Lock core shell bottom is coupling part, and the part corresponding with hexagonal part connects, radially solid Determine hexagonal part；

Lock core is located in lock core shell, and its underpart is helicitic texture, and rib block is threadeded more than one；

Connect boom end and be set to interior many ribs hole, with the many ribs hole insertion on hexagonal part；Many ribs block in described hexagonal part and Many ribs in the hole of connecting rod moves；

Connecting rod bottom pass through jump ring with telescopic joint.

When this utility model uses, connecting rod one end is fixedly connected with the central principal axis 10 in the bottle gouard moved by hands 20 of automobile； The hexagonal part part of the connecting rod other end is stretched out outside car body, and when being not inserted into key 9, many ribs block is not subjected to displacement, so when rotation Hexagonal part, hexagonal part dallies, and connecting rod does not turn, and bottle gouard moved by hands does not work, and now plays anti-theft function, reaches Anti-dismantling spare tyre 40 purpose.

Because this utility model is when using, understands some between hexagonal part and bottle gouard moved by hands shell and be exposed, be Prevent someone from pulling rotation using exposed parts box spanner, reach the purpose of stealing spare tyre, this utility model is in connecting rod Middle part, is cased with sleeve pipe in the connecting rod between hexagonal part and bottle gouard moved by hands shell；Accordingly even when pulling sleeve rotating with pliers, The connecting rod of the inside also will not rotate, and sleeve pipe idle running serves protective effect.

This utility model overcomes the shortcoming of prior art, rational in infrastructure, is hardly damaged using on automobile spare tire carrier, has Imitate reaches anti-theft function.This utility model structure is more practical rationally, using safer reliability.

Specific embodiment

Embodiment 1, is shown in accompanying drawing 1～7, accompanying drawing 9～12.

A kind of Anti-theft spare wheel carrier of vehicle connecting rod structure, is connected boom end and is connected with hexagonal part by jump ring 50；

Hexagonal part internal upper part is provided with lock；Many ribs hole 12 is set in the middle part of hexagonal part, and bottom is connected with connecting rod；

Lock is made up of with lock core 3 lock core shell 2；Lock core is rotated with lock core shell and is connected；Lock core shell pass through jump ring 50 with Hexagonal part connects, axial restraint hexagonal part；Lock core shell bottom is coupling part 22, and the part corresponding with hexagonal part connects, Described lock core shell top and lower frame portion are in integral cylinder, and described lower connecting part partial cross-section is many prismatics, hexagonal The shape that part is attached thereto part is also many prismatics, radially fixed hexagonal part；

Lock core is located in lock core shell, and described lock core is that lock core bottom is screw rod, many ribs with many ribs block screw connection structure Block is threaded through hole, and both are threaded；

Lock core shell 2 end is connected with lock core by a step 21, plays position-limiting action.

Connecting rod 5 end is set to interior many ribs hole 51, with the many ribs hole insertion on hexagonal part；Many ribs block 4 is in described hexagonal Many ribs in the hole of part and connecting rod moves；

Connecting rod bottom is connected with sleeve pipe 6 by jump ring 50.

At least provided with alignment grooves or registration holes 11 on hexagonal part inwall, the connecting rod part corresponding with hexagonal part also sets Put a location hole 52, location hole is built with positioning bead 7 and spring 8；Para-position well width or para-position bore dia are less than the straight of positioning bead Footpath.

Embodiment 2, is shown in accompanying drawing 8, accompanying drawing 13～14.

Lock core bottom is screwed hole, and many ribs block top is raised screw rod 41.This sound construction, is hardly damaged.

Described lock core shell top and lower frame portion are in integral cylinder, and described lower connecting part partial cross-section is ellipse Shape,

The shape that hexagonal part is attached thereto part is also ellipse,

Other can be with embodiment 1.

Embodiment 3, is shown in accompanying drawing 15～16.

Described lock core shell top and lower frame portion are in integral cylinder, and described lower connecting part partial cross-section is convex-concave Shape,

The shape that hexagonal part is attached thereto part is also convex concave.

Other can be with embodiment 1.

Embodiment 4.See accompanying drawing 17～18.

Described lock core shell section is many prismatics, and the part that hexagonal part is attached thereto is identical with the shape of lock core shell, For many prismatics.

Other can be with embodiment 1.

Embodiment 5.See accompanying drawing 19～20.
