The sliding device is arranged at the bottom of the seat plate; the lower end of the sliding device is connected with a regulating tray; the regulating tray is connected with an air pole and a foot stand; the sliding device consists of an upper sliding plate and a lower sliding plate; the lower sliding plate is provided with chutes; the seat plate is fixed at the upper end of the upper sliding plate and both side ends of the upper sliding plate are arranged in the chutes of the lower sliding plate, so that back-and-forth relative displacement of the seat plate and the foot stand is implemented and the problem of inconvenience in regulation on the distance between the seat plate and an office table of rotary chairs without sliding wheels is solved.

Description

A kind of chair with carriage

Technical field

The present invention relates to a kind of adjustable chair.

Background technology

At present, the market of swivel chair is not only extensively to office, and a lot of family expenses furniture also adopt swivel chair, swivel chair is because it moves flexibly, it is comfortable and parent that be subjected to the user looks to sit sense, on a lot of Foot support for swivel chair pulley is arranged, like this user can slide according to own build 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 the fixing feet cushion, some even tables and chairs are Contiuum types, but this class swivel chair is very inconvenient when regulating longitudinal separation, even the tables and chairs Contiuum type can not regulate longitudinal separation, this can become very inconvenient for some different build people.

Summary of the invention

The technical issues that need to address of the present invention are, a kind of chair with carriage is provided, and have solved the user can not regulate the longitudinal separation between chair and the desk very easily when using the chair of fixing feet cushion or tables and chairs Contiuum type problem.

Technical scheme of the present invention is: a kind of chair with carriage, comprise seat board, seat board bottom centre is installed with the swivel chair adjusting device, it is characterized in that comprising in the described swivel chair adjusting device carriage, carriage is made up of upper slide and lower skateboard, and the lower skateboard both sides are provided with chute, and upper slide upper surface and seat board are fixed, the upper slide two side ends is installed in the chute of lower skateboard, and the lower skateboard lower surface connects regulates pallet and foot rest.

Preferably, described upper slide longitudinal cross-section profile comprises inverted U-shaped mid portion and is connected the flank of U-shaped oral area both sides that two flanks all are provided with jagged gear groove, can lock a plurality of positions.

Preferably, described chute inwall fixedly has 2 clamps, is installed on two vertex positions of chute respectively.

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 the slideway, can be free to slide.

Preferably, middle part, a wherein side of described lower skateboard is provided with pin-and-hole, is interspersed with handle in the pin-and-hole, and handle one end inserts the gear groove, can play the effect of locking gear.

Preferably, described Handle axis is to being provided with annular protrusion near place, lower skateboard side, between the side of annular protrusion and lower skateboard spring is installed, both ends of the spring face annular protrusion and lower skateboard side is respectively fixed, handle inserts the lower skateboard inside part and is provided with the jump ring groove, spring can allow handle automatically reset, and the jump ring groove can prevent that handle breaks away from from pin-and-hole.

Preferably, described Handle axis is to being provided with annular shank, more convenient operation from farthest, lower skateboard side.

After adopting technique scheme, the present invention has following advantage: upper slide can slide in the chute of lower skateboard, because upper slide is fixed in seat board, lower skateboard is fixed with the adjusting pallet, regulating pallet is connected with foot rest with the gas bar, thereby and realized relatively moving between seat board and the foot rest, the user just can be in the longitudinal separation of the situation lower adjusting seat plate of mobile foot rest not, as optimization, at upper slide the gear groove is set, lower skateboard arranges the handle of a spacing usefulness, just can play the locking effect to upper slide, thereby more convenient.

Description of drawings

Accompanying drawing 1 is for having the inverted schematic diagram of swivel chair of carriage;

Accompanying drawing 2 is the front elevational schematic of carriage;

Accompanying drawing 3 for carriage along A to overlooking partial schematic sectional view.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further:

As shown in Figure 1 to Figure 3, the present invention mainly comprises seat board 5, seat board 5 bottom centre are equipped with the swivel chair adjusting device, this adjusting device comprises carriage and regulates 6 two parts of pallet, directly contact the hard-wired carriage that is with seat board 5, carriage is then fixing with adjusting pallet 6, regulating pallet 6 directly is connected with foot rest 7 with gas bar 72, fixed foot pad 71 is installed on the foot rest 7, foot pad 71 can not slide, described carriage mainly is made up of upper slide 1 and lower skateboard 2, upper slide 1 longitudinal cross-section profile comprises inverted U-shaped mid portion and is connected the flank of U-shaped oral area both sides, two flanks all are provided with jagged gear groove 11, the upper surface is provided with screw hole, by screw hole and seat board fixed installation, the inside bending of lower skateboard 2 two side ends, dogleg section and lower skateboard 2 upper surfaces form chute, the place, two summits of chute fixedly has clamp 3 respectively, because two chutes are arranged, 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 the slideway 31, and can slide, the place, centre position, side of lower skateboard 2 is provided with pin-and-hole, handle 4 one ends pass pin-and-hole, and the gear groove 11 of insertion upper slide 1, can lock the slip of upper slide 1, handle 4 interludes are provided with an annular protrusion 42, make things convenient for 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 ends are inserted in the gear groove 11, spring 41 is in non-compressed state, upper slide 1 is in locking state, can not slide, when handle 4 when layback goes out outward, when namely an end breaks away from gear groove 11, spring 41 is stretched, this moment, upper slide 1 can slide, because upper slide 1 is fixing with seat board 5, namely realized the slip of seat board 5, and lower skateboard 2 indirect connections is foot rest, still be in motionless state, realized the relative displacement of seat board 5 with respect to foot rest on the whole, when release handle 4 again, because spring 41 is stretched before, this moment, trip spring 41 can automatically reset, make handle 4 insert again in the gear groove after adjusting, finish the adjustment of a longitudinal separation, for convenience operation, the other end at handle 4 is provided with annular shank 43, can allow operation more convenient.
