description of reference numerals: the device comprises a bottom frame-1, a top frame-2, a height adjusting device-3, a hinged support-31, an adjusting screw rod-32, a connecting block-33 and an outer cover-4.
Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.
The first embodiment is as follows:
referring to the attached drawings of the specification 1 and fig. 2, the utility model provides a leg pressing device, it includes chassis 1, roof-rack 2, heightening device 3, is equipped with the heightening device between chassis 1 and the roof-rack 2, heightening device includes two articulated brackets 31 of a set of relative setting, and articulated bracket 31 upper end is articulated through the pivot with roof-rack 2, and articulated bracket 31 lower extreme is articulated through the pivot with chassis 1, runs through adjusting screw 32 between two articulated brackets, and two articulated brackets 31 are opposite with adjusting screw 32 complex bolt direction. Because two articulated brackets are opposite with the bolt direction of adjusting the lead screw complex, the rotatory regulation lead screw, adjust the lead screw and drive two articulated brackets and move in opposite directions or opposite direction simultaneously, two articulated brackets are propped up or are transferred, and two articulated brackets height are adjusted to the roof-rack height is adjusted.
The adjusting screw rod can drive the two hinged supports to simultaneously and synchronously operate, and the operation is simple and convenient; the two hinged supports support the top frame and the bottom frame, and the structure is stable.
The second embodiment is as follows:
in order to further enhance the structural stability of the leg pressing device, referring to the accompanying drawings 3 and fig. 4 of the specification, the leg pressing device comprises an underframe 1, a top frame 2 and a height adjusting device 3, wherein the height adjusting device is arranged between the underframe 1 and the top frame 2, the height adjusting device in the embodiment comprises two groups of hinged supports, two groups of hinged supports 31 are arranged between the underframe and the top frame, the two groups of hinged supports are arranged in a front-back parallel mode, a connecting block 33 is arranged between the two parallel hinged supports, an adjusting screw 32 penetrates between the two opposite connecting blocks 33, and the directions of the two connecting blocks 33 and the bolt matched with the adjusting screw 32 are opposite.
