Abstract

The invention discloses a detachable window lifter which comprises an upper shell body, a base, a connecting rod, a worm, a gear arm and a transmission gear, wherein a shell body protruding cavity and a boss are arranged on the upper shell body, a base protruding cavity, a dowel and a locating sleeve are arranged on the base, the worm is arranged between the protruding cavity of the upper shell body and the protruding cavity of the base, the gear arm is provided with a gear and a hole, a connecting hole and a fixing hole are formed in the connecting rod, the worm is meshed with a gear arranged on the gear arm through the transmission gear, and the connecting rod is sleeved on the locating sleeve through the fixing hole and the transmission gear in an inserted mode. Due to the fact that protrusions and the boss are arranged, the window lifter can be not riveted. Parts of the window lifter can be detached and replaced, and stability is improved. The detachable window lifter has the advantages of being simple in structure, low in cost, applicable to large-scale popularization and application, not prone to slipping, and good in stability. Moreover, people can detach and replace the parts independently when the lifter breaks down, the detachable window lifter does not need to be replaced integrally, and resources and cost are greatly saved.

Description

The detachable window regulator

Technical field

The present invention relates to a kind of window regulator, especially a kind of detachable window regulator.

Background technology

Window regulator kind in the market is a lot, but window regulator is all riveted and is connected, for example number of patent application is that 200820122365.1 Chinese patent has just been announced a kind of like this window regulator, though this window regulator is easy for installation and firm, but because window regulator is all riveted and is connected, after being arranged in the window regulator, damage parts can only integral body change, can't dismantle the indivedual repairings in back, and there is not step on the housing, very smooth the skidding easily in surface influences the window regulator work quality, causes whole stability also not high.

Summary of the invention

The objective of the invention is to provide for the deficiency that solves above-mentioned technology that a kind of stability is high, dismountable detachable window regulator.

In order to achieve the above object, a kind of detachable window regulator that the present invention is designed, it comprises upper shell, base, connecting rod, worm screw, gear arm and travelling gear, it is characterized in that described upper shell is provided with case protrusion chamber and boss, be provided with the pedestal lobe chamber at base, pin and positioning sleeve, worm screw is located between upper shell projection chamber and the pedestal lobe chamber, be provided with gear and hole at the gear arm, be provided with connecting hole and fixing hole at connecting rod, worm screw is meshed by travelling gear with gear on the gear arm, connecting rod by fixing hole and travelling gear sleeve on positioning sleeve, because be provided with projection and boss, window regulator no longer must be riveted and be connected, and the part of the window regulator that is can dismounting and change, but also has improved stability.

For the detachable window regulator can be moved normally, the gear arm is provided with alignment pin, and the connecting hole on the connecting rod is connected with hole on the gear arm by alignment pin, and the gear arm can rotate automatically around alignment pin, makes that the operation of detachable window regulator is more steady.

In order to make cooperation more stable, be provided with the rectangle step around the boss on the upper shell, be provided with groove around positioning sleeve, the positioning sleeve of socket is fixed on the boss on the pin, rectangle step around boss is meshed with the groove of positioning sleeve, has improved the stability of window regulator greatly.

A kind of detachable window regulator that the present invention obtains, simple in structure, cost is low, be suitable for large range promotion use, and be difficult for skidding, have good stable, but the independent replacement part of integral demounting energy need not integral replacing during the window regulator fault, has saved resource and expense greatly.
