Background technology
At present, the market of swivel chair is not only extensively to office, and a lot of family expenses furniture also adopts swivel chair, swivel chair is because it moves flexibly, sitting sense parent comfortable and that be subject to user looks at, on a lot of Foot support for swivel chair, there is pulley, like this user according to own build, can slide that pulley is adjusted and desk between before and after distance, but pulley has certain limitation, because a lot of offices or household all adopt some wood floors or material floor that some are easy to wear, the slip of pulley these floors of will certainly wearing and tearing, so what a lot of swivel chairs adopted is fixing feet cushion, some even tables and chairs are Contiuum types, but this class swivel chair is very inconvenient when regulating longitudinal separation, even tables and chairs Contiuum type can not regulate longitudinal separation, this can become very inconvenient for some different build people.
In addition, the foot rest of a lot of swivel chairs considers to adopt aluminium alloy compression casting to make for intensity, and surface finish, user's easy landing when both feet are stepped on foot rest sometimes, and when user's sitting posture is more forward even sometimes, both feet are stepped on sky landing and are caused the whole people can landing from swivel chair.
Utility model content
The utility model technical issues that need to address are, a kind of improvement structure of anti-skidding swivel chair is provided, solved user and can not regulate very easily the problem of the longitudinal separation between chair and desk when using the chair of fixing feet cushion or tables and chairs Contiuum type, and prevented from easily stepping on the hidden danger of sky landing when both feet are stepped on foot rest.
The technical solution of the utility model is: a kind of improvement structure of anti-skidding swivel chair, comprise seat board, seat board bottom centre is installed with Revolving chair adjusting device, adjusting device is connected with gas bar and foot rest, it is characterized in that described Revolving chair adjusting device comprises a carriage, carriage is comprised of upper slide and lower skateboard, lower skateboard both sides are provided with chute, upper slide upper surface and seat board are fixed, upper slide two side ends is installed in the chute of lower skateboard, lower skateboard lower surface connects adjusting device, and described foot rest is provided with anti-skid structure.
Preferably, described upper slide longitudinal cross-section profile comprises inverted U-shaped mid portion and is connected to the flank of U-shaped oral area both sides, and two flanks are all provided with jagged shift slot, can lock a plurality of positions.
Preferably, described chute inwall is fixed with 2 clamps, is installed on respectively two vertex positions of chute.
Preferably, described clamp is rectangular column, and rectangular column one side is provided with slideway along its length, and two flanks of described upper slide are located in slideway, can be free to slide.
Preferably, a wherein middle part, side of described lower skateboard is provided with pin-and-hole, is interspersed with handle in pin-and-hole, and shift slot is inserted in handle one end, can play the effect of locking gear.
Preferably, described Handle axis is to being provided with annular protrusion near place, lower skateboard side, between annular protrusion and the side of lower skateboard, spring is installed, both ends of the spring face respectively annular protrusion and lower skateboard side is fixed, handle inserts lower skateboard inside portion and is arranged with jump-ring slot, spring can allow handle automatically reset, and jump-ring slot can prevent that handle from departing from from pin-and-hole.
Preferably, described Handle axis is to being provided with annular shank, more convenient operation from farthest, lower skateboard side.
Preferably, described anti-skid structure is and integrated several boss of foot rest that the non slip surface that boss forms can finely play anti-skidding effect.
Preferably, described foot rest is radially level toward the head of extension, with the middle part of foot rest at angle, the head of level is more suitable for both feet and places.
Adopt after technique scheme, the utlity model has following advantage: upper slide can slide in the chute of lower skateboard, because upper slide is fixed on seat board, lower skateboard and adjusting tray are fixed, adjusting tray is connected with foot rest with gas bar, thereby and realized relatively moving between seat board and foot rest, user just can be in the longitudinal separation of the situation lower adjusting seat plate of Mobile foot stool not, as optimization, at upper slide, shift slot is set, lower skateboard arranges the handle of a spacing use, just can play locking effect to upper slide, thereby more convenient, on foot rest, be provided with anti-skid structure simultaneously, allow user's both feet be not easy to step on sky landing from foot rest, thereby when allowing swivel chair reach an own comfortable distance, can prevent again both feet landing from foot rest.
Accompanying drawing explanation
Accompanying drawing 1 is the inverted schematic diagram of swivel chair with carriage;
The front elevational schematic that accompanying drawing 2 is carriage;
Accompanying drawing 3 is carriage along A to overlooking partial schematic sectional view;
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further:
As shown in Figure 1 to Figure 3, the utility model mainly comprises seat board 5, seat board 5 bottom centre are provided with Revolving chair adjusting device, this adjusting device comprises carriage and 6 two parts of adjusting tray, directly contacting hard-wired with seat board 5 is carriage, carriage is then fixing with adjusting tray 6, adjusting tray 6 is directly connected with foot rest 7 with gas bar 72, fixed foot pad 71 is installed on foot rest 7, foot pad 71 can not slide, described carriage is mainly comprised of upper slide 1 and lower skateboard 2, upper slide 1 longitudinal cross-section profile comprises inverted U-shaped mid portion and is connected to the flank of U-shaped oral area both sides, two flanks are all provided with jagged shift slot 11, upper surface is provided with screw hole, by screw hole and seat board, fixedly mount, the inside bending of lower skateboard 2 two side ends, dogleg section and lower skateboard 2 upper surfaces form chute, the place, Liang Ge summit of chute is fixed with respectively clamp 3, because there are two chutes, so one has 4 clamps in this example, clamp 3 is rectangular column, rectangular column one side is provided with slideway 31 along its length, two flanks of described upper slide 1 are located in slideway 31, and can slide, the place, centre position, side of lower skateboard 2 is provided with pin-and-hole, handle 4 one end are through pin-and-hole, and insert the shift slot 11 of upper slide 1, can lock the slip of upper slide 1, handle 4 interludes are provided with an annular protrusion 42, facilitate mounting spring 41, spring 41 is positioned between annular protrusion 42 and lower skateboard 2 sides, spring 41 two ends are fixed with annular protrusion 42 and lower skateboard 2 sides respectively, during adjusting, when handle 4 one end are inserted in shift slot 11 when interior, spring 41 is in non-compressed state, upper slide 1 is in locking state, can not slide, when handle 4 is when layback goes out outward, while being one end disengaging shift slot 11, spring 41 is stretched, now upper slide 1 can slide, because upper slide 1 is fixing with seat board 5, realized the slip of seat board 5, and lower skateboard 2 indirect connections is foot rest, still in motionless state, realized on the whole the relative displacement of seat board 5 with respect to foot rest, when release handle 4 again, because spring 41 is before stretched, now trip spring 41 can automatically reset, make handle 4 again insert in the shift slot after adjusting, complete the adjustment of a longitudinal separation, for handled easily, the other end at handle 4 is provided with annular shank 43, can allow operation more convenient.
