Abstract
The utility model provides a kind of device for tables and chairs Height Adjustment, it is characterized in that: there is intermeshing bolt and nut secondary, nut is fixed on base, the top of screw rod is installed with the bevel gear of the dead in line of an axis and screw rod, screw rod is hubbed in a housing, the bevel gear setting firmly in housing and the intermeshing formation bevel gear pair of the bevel gear of above-mentioned screw tip; Housing connects the face of tables and chairs.The gear shaft of the bevel gear setting firmly in housing stretches out outside housing and is connected with the turning handle outside housing.The utility model is by the engagement of bevel gear, make bolt rotary, the cooperation of bolt and nut pair makes screw rod produce elevating movement, and then drive desktop elevating movement, thereby realize the Height Adjustment between desktop and base, this adjustment only needs turning handle to realize, easy to operate, and this Height Adjustment is stepless, can realize any Height Adjustment in adjusting range.
Description
Technical field
The utility model belongs to a kind of furnature construction, relates in particular to a kind of device that regulates tables and chairs height.
Background technology
Existing common tables and chairs height adjuster, generally to use inside and outside leg tubular construction, tables and chairs face is fixed on the leg pipe that is positioned at top, and interior outer tube is mutually sheathed, and in outer tube, offers locating hole, bolt is realized location through leg pipe in locating hole contact, or on interior leg pipe, also offer locating hole, make the position, hole of interior outer tube locating hole corresponding, through bolt-locking, thereby the location of outer tube in realizing, and unclamp that bolt just can move up and down interior outer tube and the adjustment that realizes tables and chairs height.This structural adjustment is loaded down with trivial details, and adjusting range can only also still have level adjustment at fixing several height points, and people and desktop or seat cannot reach real matched.
Utility model content
The utility model provides a kind of device for tables and chairs Height Adjustment, its objective is and solves the shortcoming that prior art exists, and makes the adjusting operation of tables and chairs height convenient, realizes the stepless adjustment of tables and chairs height.
The utility model solves the technical scheme that its technical problem adopts:
A kind of device for tables and chairs Height Adjustment, it is characterized in that: there is intermeshing bolt and nut secondary, nut is fixed on base, the top of screw rod is installed with the bevel gear of the dead in line of an axis and screw rod, screw rod is hubbed in a housing, the bevel gear setting firmly in housing and the intermeshing formation bevel gear pair of the bevel gear of above-mentioned screw tip; Housing connects the face of tables and chairs.
The gear shaft of the bevel gear setting firmly in housing stretches out outside housing and is connected with the turning handle outside housing.
Usefulness of the present utility model is:
The utility model is by the engagement of bevel gear, make bolt rotary, the cooperation of bolt and nut pair makes screw rod produce elevating movement, and then drive desktop elevating movement, thereby realize the Height Adjustment between desktop and base, this adjustment only needs turning handle to realize, easy to operate, and this Height Adjustment is stepless, can realize any Height Adjustment in adjusting range.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model three-dimensional exploded view;
Fig. 2 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, the below of face that the utility model is mounted in tables and chairs is for regulating the structure of tables and chairs height.
It has a nut 6, and it is upper that nut 6 is fixed on base (base is not shown in the figures),
In nut 6, be provided with a screw rod 5, the top of screw rod 5 is installed with the straight bevel gear 4 of the dead in line of an axis and screw rod 5.Cover 1 and cover 2 engagings form a housing, and this housing is connecting the face of tables and chairs, and the face of so-called tables and chairs refers to the face of desk or the face of chair.The annular groove 51 of screw rod 5 upper ends is fastened in the through hole of housing formation, the upper and lower surface of annular groove 51 lay respectively at housing inside and outside, screw rod 5 can rotate like this, thereby make screw rod 5 be hubbed on rotationally in housing, but moving up and down of screw rod 5 also can drive moving up and down of housing, the moving up and down of final screw rod 5 can drive the moving up and down of face of tables and chairs.
In housing, be installed with a straight bevel gear 3, the axis of this bevel gear 3 is vertical with bevel gear 4, and bevel gear 3 and bevel gear 4 keep intermeshing formation bevel gear pair always.
The gear shaft 31 of bevel gear 3 stretches out outside housing and is connected with the turning handle 17 outside housing.
In the present embodiment, outside nut 6 and screw rod 5, be arranged with support 11, support 11 on cover 1 and cover 2, plays beauty function with screw fastening.
During actual use, rotate turning handle 17, bevel gear 3 is rotated, band dynamic bevel gear 4 rotates, thereby screw rod 5 rotates, because nut 6 is fixed on base, so screw rod 5 can only rise or decline, the final face rise and fall that drive tables and chairs, user can accurately rotate turning handle 17, realizes the stepless lifting of the face of tables and chairs.
Claims (2)
