座體升降結構Seat lifting structure

　　本創作與座體升降結構有關，尤指一種滑塊與座體間以鳩尾形狀之結構相互靠合以達限位作用的座體升降結構。The creation is related to the lifting structure of the seat body, in particular to a lifting structure of the seat body in which the structure of the tail-shaped shape of the slider and the seat body abut each other to reach the limit position.

　　如第４圖所示，為習用之一種座體升降結構，其由下而上係以一滑座４、一滑塊５及一升降座６疊設所組成，並利用該滑塊５及滑座４、升降座６之抵靠面的斜度相互靠合，以達成藉由推動該滑塊５而令該升降座６產生上下的位移。其中該滑塊５之底面及頂面兩側分別凹設有一限位軌槽５１、５２，而該滑座４及該升降座６靠合於該滑塊５之抵靠面的兩側於各該限位軌槽５１、５２的位置亦對應設有各該限位凸條４１、６１，該滑座４及該升降座６藉由各該限位凸條４１、６１伸入該滑塊５之限位軌槽５１、５２中，而可限制該滑塊５在推動該升降座６升降的過程中，僅能沿一前後之直線方向滑移，避免朝兩側傾倒。As shown in FIG. 4, it is a conventional seat lifting structure which is composed of a sliding seat 4, a slider 5 and a lifting seat 6 stacked from bottom to top, and uses the slider 5 and sliding. The inclination of the abutment surface of the seat 4 and the lifting base 6 abut each other to achieve a vertical displacement of the lifting base 6 by pushing the slider 5. The bottom surface of the slider 5 and the two sides of the top surface are respectively recessed with a limiting rail groove 51, 52, and the sliding seat 4 and the lifting base 6 are respectively engaged on both sides of the abutting surface of the slider 5 The position of the limiting rail grooves 51 and 52 is correspondingly provided with the limiting ribs 41 and 61. The sliding seat 4 and the lifting base 6 extend into the slider 5 by the limiting ribs 41 and 61. In the limit rail grooves 51, 52, the slider 5 can be restrained from sliding in a straight line direction in the forward and backward directions during the lifting and lowering of the lifting block 6, so as to avoid tilting toward both sides.

　　然而此習用結構中，各該限位軌槽５１、５２及各限位凸條４１、６１分別相對於該滑塊５、該滑座４及該升降座６而言，均為垂直於其本體的結構形狀，此設計雖可達到組裝容易且可限制該滑座４及升降座６左右位移的作用，但在該滑塊５進行長期滑動作動後，則會因組裝所產生之基本間隙外，更容易因各該限位軌槽５１、５２及各限位凸條４１、６１間相互摩擦而產生額外磨耗之間隙，進而導致作動過程中發生上下震動的情形，進而使該升降座６相應產生震動而致有不穩固的狀態發生，同時也影響該升降座６進行高度升降的精準度。However, in the conventional structure, each of the limiting rail grooves 51, 52 and the limiting ribs 41, 61 are perpendicular to the body of the slider 5, the sliding seat 4 and the lifting base 6, respectively. The structural shape, although the design can be easily assembled and can limit the displacement of the slide 4 and the lift 6 to the left and right, but after the long-term sliding action of the slider 5, the basic gap generated by the assembly will be It is more easy to generate an additional wear gap due to mutual friction between the limit rail grooves 51, 52 and the limit ribs 41, 61, thereby causing up and down vibration during the operation, thereby causing the lift seat 6 to be correspondingly generated. The vibration causes an unstable state to occur, and also affects the accuracy of the height raising and lowering of the lifting seat 6.

　　有鑑於此，故如何解決上述問題即為本創作所欲解決之首要課題，因此本案創作人經過不斷的苦思與試作後才終於有本創作之產生。In view of this, how to solve the above problems is the primary problem that the creative office wants to solve. Therefore, the creators of this case finally have the creation of this creation after continuous hard work and trials.

Causes the overall bumping and shaking to affect the accuracy of the lifting height of the lifting seat.
