Description

Self-powered platform

Technical field

The present invention relates to tablet computer bearing technology fields, specifically be a kind of self-powered platform.

Background technique

With the continuous development of society, flat-panel monitor, tablet computer etc. are also more more and more universal in average family, therewith The bracket to match comes into being, and the self-powered platform for loading plate computer of the prior art is typically placed in desktop Or used on table top, self-powered platform in the prior art is largely that the bullet of rising is provided using mechanical spring or torsional spring Power, and the structure that strut is usually used comes so that table top rises or falls relative to undersetting, and structure is more complicated, and platform The adjusting of face height is more troublesome.

Summary of the invention

The technical problem to be solved by the present invention is to overcome the defect of the above prior art, provide that a kind of structure is simple, height Self-powered platform easy to adjust.

The technical solution of the invention is as follows, provides a kind of self-powered platform having following structure: it includes lifting work Make playscript with stage directions body, the self-powered platform ontology include desktop, upper bracket, undersetting and be connected to upper bracket and undersetting it Between at least one set of X-type elevating mechanism, the desktop is fixedly connected on the top of upper bracket, and every group of X-type elevating mechanism includes Middle part is hingedly in the first strut and the second strut of X-type, and the upper end of first strut and upper bracket are hinged, and the first strut Hinged one first sliding block in lower end, first sliding block are slidably fitted on undersetting；The lower end of second strut and lower branch Seat is hinged, and hinged one second sliding block in upper end of the second strut, second sliding block are slidably fitted on upper bracket；Under described Support is equipped with the lockable mechanism of limitation the first sliding block sliding；Every group of X-type elevating mechanism further include one for offset or It is hinged in the middle part of the gas spring of partial offset upper bracket load-bearing, one end of the gas spring and the first strut, the other end of gas spring It is hinged with upper bracket.

After using the above structure, self-powered platform of the present invention compared with prior art, has the advantage that the lifting work Platform provides support force by gas spring, for counteracting or partial offset upper bracket load-bearing, can rest on workbench in this way Arbitrary height, structure is simple, and cost is relatively low；And this X-type elevating mechanism is used, and during upper bracket lifting, upper branch The front-rear position of seat will not change, in addition, lockable mechanism can lock X-type elevating mechanism, make the desktop of X-type elevating mechanism Height is fixed, and the load-bearing capacity of self-powered platform can be improved in this way, and lockable mechanism is opened, with hand overcome the elastic force of gas spring come The height for adjusting upper bracket and desktop unclamps lockable mechanism, to make first after the height adjustment of upper bracket and desktop Sliding block limit slippage locks X-type elevating mechanism, therefore the self-powered platform structure is simple, height adjustment is convenient.

Preferably, the undersetting is equipped with the lockable mechanism of limitation the first sliding block sliding, refer to the undersetting On be connected with the first sliding rail, first sliding block is slidably fitted on the first sliding rail, and the first sliding block be equipped with it is multiple along it The location hole of length direction distribution；Undersetting on the outside of first sliding block is equipped with a box body, is equipped with one in the box body The removable pin of location hole can be inserted into or be detached from free end, and be slidably matched in box body and one removable pin can be driven mobile and make removable pin Free end be detached from location hole sliding panel.When the lockable mechanism acts, sliding panel is pulled to slide in box body, sliding panel drives The mobile free end for making removable pin of removable pin is detached from location hole, and the first sliding block is slided along the first sliding rail at this time, makes X-type elevating mechanism Adjustable height unclamps sliding panel after upper bracket is elevated to certain altitude, the free end of removable pin again insertable into location hole with Limit the sliding of the first sliding block.

As an improvement, the box body internal clearance, with unification removable pin seat, the removable pin is connected on movable key seat, And a reset spring is arranged on removable pin, the inner wall of one end of the reset spring and movable key seat offsets, reset spring it is another The inner wall of one end and box body offsets, and when reset spring is in compressive state, the free end of the removable pin is detached from the first sliding block Location hole, it is described activity key seat bottom be equipped with the first guiding surface；The sliding panel is equipped with and the first guiding surface The second guiding surface matched, and when sliding panel is slided to outside box body, it is oblique that second guiding surface squeezes the first guiding The elastic force that face makes movable key seat overcome reset spring is displaced outwardly.Pull sliding panel when sliding in box body, the on sliding panel The elastic force that first guiding surface of two guiding surface Compressive activities key seat bottoms makes movable key seat overcome reset spring is displaced outwardly, The free end of the removable pin on movable key seat is detached from location hole at this time, and the first sliding block is slided along the first sliding rail, makes X-type elevating mechanism Adjustable height unclamps sliding panel after upper bracket is elevated to certain altitude, and movable key seat drives work under the elastic force of reset spring Dynamic pin, which resets, is inserted into the free end of removable pin in location hole to limit the sliding of the first sliding block, meanwhile, the first of movable key seat is led The second guiding surface for squeezing sliding panel to inclined-plane makes to slide sheet reset.

As an improvement, the outer end of the sliding panel connects a drag-line, the drag-line is equipped with a spring, the spring The outer end side wall of one end and sliding panel offsets, and the other end of spring and the inner wall of box body offset；Connection one is pulled on the upper bracket The outer end of hand, the spanner and drag-line connects.The sliding of sliding panel is controlled using spanner and drag-line, which, which plays, makes to slide The effect that movable plate resets.

Preferably, being connected with the second sliding rail on the upper bracket, it is sliding that second sliding block is slidably fitted in second On rail.

As an improvement, at least one set X-type elevating mechanism is two groups of X-type elevating mechanisms, and it is separately positioned on upper bracket Two sides, connected with transverse slat between two groups of X-type elevating mechanisms.It can make the X-type liter of upper bracket two sides using this structure Descending mechanism moves synchronously, but also can reinforce the mechanical strength and stability of self-powered platform.

The self-powered platform ontology further includes keyboard support, and the keyboard support is connect by connecting plate with upper bracket. The keyboard support can be placed for keyboard.
