Description

The locking device of foldable table for notebook-computer

Technical field

The utility model relates to a kind of foldable table for notebook-computer parts, mainly is the locking for foldable table for notebook-computer.

Background technology

Notebook computer has progressively replaced desktop computer at present, notebook is because its portable people who uses is more and more, a lot of people like using in the place of leisure, as first-class with sofa on the bed, therefore need easily computer desk placing laptop, existing clutch locking device, such as Chinese patent 201977100u, external lock collar and internal lock collar that this clutch locking device adopts all have been covered with the locking groove, often block and to rotate, and banking stop do not have the limit rib support, and often rotation bending has affected locking effect, and set lever is to adopt the single face lock projection, can only lock on one side, another side can not be locked, and has also affected result of use.

Summary of the invention

The purpose of this utility model is to provide a kind of locking effect good, the locking device of foldable table for notebook-computer easy to use.

In order to achieve the above object, the technical solution of the utility model is: a kind of locking device of foldable table for notebook-computer, comprise the external lock collar, the internal lock collar, locking pin, set lever and spring, has the locking groove on the one end end face of external lock collar, has the locking teeth with the locking groove fit on the one end end face of internal lock collar, the other end has the U-shaped articulated slab, one end of locking pin has the backstop flange, the other end passes the outer locking mesopore of external lock collar and the internal locking mesopore of internal lock collar, and hinged with set lever, spring housing is contained on the locking pin, one end and set lever offset, the other end and external lock collar offset, has the first plane domain on the one end end face of described external lock collar, have second plane domain corresponding with the first plane domain on the one end end face of internal lock collar, also has banking stop between spring and the set lever, the other end of external lock collar has a plurality of axial location muscle, have the radial groove with a plurality of axial location muscle corresponding matching on the banking stop, the both sides, articulated section of set lever all have lock projection.

Also has hinge hole on the U-shaped articulated slab of described internal lock collar.

Described the first plane domain and the second plane domain are fan-shaped.

After adopting said structure, owing to have several the first plane domains on the end face of described external lock collar, has the second plane domain that matches with the first plane domain on the end face of internal lock collar, therefore the first plane domain and the second plane domain cooperate the stuck phenomenon that produces in the time of suitably reducing locking groove and locking teeth locking, locking effect is good, can be not stuck, and also has banking stop between spring and the set lever, have a plurality of axial location muscle on another end face of external lock collar, has the radial groove that is complementary with a plurality of axial location muscle on the banking stop, therefore banking stop can make set lever when locking, and more reliable, locking effect is better, the both sides, end of set lever all have lock projection again, therefore set lever can all play the locking effect in the two sides when locking, uses convenient.
