Specific embodiment

The utility model is described in further detail combined with specific embodiments below, but the embodiment party of the utility model Formula is without being limited thereto.

As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, the height-adjustable bench of the utility model, including stool surface 1 and stool frame 2.The stool surface 1 can adjust its difference in height between the stool frame 2 by height adjustment mechanism, and stool frame 2 is such as existing Conventional bench is the same, and there are three usual tools or four supporting legs, in figure by taking four more common supporting legs as an example.The height adjustment The specific structure of mechanism is as follows:

X-shaped made of the height adjustment mechanism includes screw rod 31, driving member 32 and is hinged as two spokes 331 Support frame 33.The screw rod 31 is rotationally connected with the bottom of the stool surface 1, the hand of spiral of 31 two sides of screw rod on the contrary, I.e. side is forward screw thread 311, and the other side is the reverse thread 312 opposite with 311 direction of rotation of forward screw thread；The transmission Part 32 is two, and one end of two driving members 32 is hingedly connected to the two sides of the stool frame 2, and the other end is divided by nut piece 321 It is not threadedly coupled with the forward screw thread 311 of 31 two sides of screw rod and reverse thread 312；The X-shaped support frame 33 is two, The two sides of the bench are located at, the bottom of X-shaped support frame 33 is installed in the stool frame 2, and top is installed on described In stool surface 1, and X-shaped support frame 33 longitudinal with the variation of difference in height between stool surface 1 and stool frame 2 can collapse or be unfolded.Normally, In X-shaped support frame 33, the hinge joint of two spokes 331 is respectively positioned on the middle part of spoke, to form the X-shaped branch of a symmetrical structure Support 33.

In one embodiment of the utility model, the driving member 32 and X-shaped support frame 33 and stool surface 1 or stool frame 2 Tie point is respectively positioned on more hidden place, that is, is usually located at the bottom of stool surface 1 or the inside of stool frame 2.

In one embodiment of the utility model, the two sides of 2 inside casing of stool frame are respectively and fixedly provided with the first connecting plate 4, institute The two sides for stating 1 bottom inside casing of stool surface are respectively and fixedly provided with the second connecting plate 5.

Further, the driving member 32 is hinged by the first otic placode 43 on the first connecting plate 4 and stool frame 2；Described The side of two connecting plates 5 is provided with second sliding slot 51, and the other side is provided with the second fixation hole 52, and first connecting plate 4 is set It is equipped with first sliding groove 41 corresponding with the second sliding slot 51 and first fixation corresponding with second fixation hole 52 Hole 42；Positioned at the bottom of the X-shaped support frame 33, one of spoke 331 is slidably connected with the first sliding groove 41, another A spoke 331 is rotatably connected with first fixation hole 42；Positioned at the top of the X-shaped support frame 33, one of spoke Item 331 is slidably connected with the second sliding slot 51, another spoke 331 is rotatably connected with second fixation hole 52.

It is described in order to reinforce height adjustment mechanism to the supportive of stool surface in one embodiment of the utility model Height adjustment mechanism further includes two connectors 34, and one end of two connectors 34 is hingedly connected in the driving member 32 of two sides Portion, the other end are hinged by the second otic placode 53 on the second connecting plate 5 and ipsilateral stool surface 1.

In one embodiment of the utility model, the driving member 32 is symmetrically put together by two steel bars, connection Part 34 is articulated between two steel bars, and after one end of steel bar installation nut piece 321 is separated from each other, nut piece 321 is installed on two Between steel bar.

In one embodiment of the utility model, the screw rod 31 is rotatably connected by axle sleeve 6 with stool surface 1, silk Bar 31 is provided with rotary head 7 by one end that one side of the stool surface is extended, and when which rotates, screw rod 31 can be rotated with it.

In one embodiment of the utility model, it is between the forward screw thread 311 and reverse thread 312 of the screw rod 31 Non-threaded changeover portion 313.

In one embodiment of the utility model, the stool surface 1 is provided with cushion course.

Since the side of screw rod 31 is forward screw thread 311, the other side is reverse thread 312, therefore, when rotary motion head 7, When screw rod 31 rotates, screw rod 31 can drive the driving member 32 of two sides to move towards or move backward by nut piece 321, and two Driving member 32 is hingedly connected to 2 two sides of stool frame again, therefore the reverse movement of two driving members 32 can drive stool surface 1 to increase, It moves towards, drives the reduction of stool surface 1.When stool surface 1 increases, the spoke that is connected with the first fixation hole 42, the second fixation hole 52 331 can rotate relative to connecting plate, and the spoke 331 being connected with first sliding groove 41, second sliding slot 51 can be slided relative to connecting plate, X-shaped support frame 33 longitudinal with the raising of stool surface 1 can be unfolded as a result, and cooperate driving member 32, connector 34 to the weight of stool surface Amount is supported；Similarly, when stool surface 1 reduces, X-shaped support frame 33 longitudinal with the reduction of stool surface 1 can be collapsed.

For the fixed bench of existing height, the bench applicability of the utility model is stronger, Ke Yigen Corresponding height is adjusted according to different demands；For the seat of existing adjustment height, the volume of the utility model compared with It is small, it is applicable to the limited occasion of family or certain spaces, and the construction of bench is also relatively easy.
