Specific embodiment
As shown in Fig. 1-Fig. 7, a kind of armrest structure for chair that liftable is adjusted, it is characterised in that: including cross bar 241, with
The housing 1 that seat body is fixedly connected and the hollow stent 2 being set in housing 1, housing 1 can accommodate hollow stent 2 in it
It sliding up and down, and 1 side of housing is provided with waist through hole 11,1 other side of housing is provided with several limit holes 12 being vertically arranged,
The top of hollow stent 2 is provided with the pull handle 21 of a lateral injection hollow stent 2, and pull handle 21 protrudes into inside hollow stent 2 at it
One end be vertically connected with reset spring 22 respectively and can slide up and down pull rod 23,23 lower part of pull rod offers inclined hole 231, horizontal
A positioning pin 242 is fixedly connected in the middle part of bar 241, the useful kidney slot slided with accommodating positioning pin 242 is arranged in hollow stent 2,
The positioning pin 242 passes through inclined hole 231 and slidable connection in kidney slot, and 241 both ends of cross bar pass through hollow stent 2 and alternating
Be plugged in waist through hole 11 and limit hole 12.
Optionally, the hollow stent 2 is T-shaped or inverted L shape, and hollow stent 2 is T-shaped in the present embodiment, and either T-type is also
Be inverted L shape hollow stent 2 can play to hollow stent 2 with respect to housing 1 slide into lower limit position when position-limiting action is provided.
Preferably, 1 outer cover of housing is equipped with dust-proof sleeve 3, to prevent foreign from the waist through hole 11
Or limit hole 12 enters internal stent, influences the transmission inside armrest, or even cause stuck situation.
Preferably, 2 inner wall of hollow stent is provided with the limit rib 25 for limiting 23 glide direction of pull rod, on the one hand
Limit rib 25 plays position-limiting action to the sliding of pull rod 23, and another aspect limit rib 25 itself constitutes sliding slot accommodating pull rod 23 and limiting
The region opposite hollow bracket 2 that position muscle 25 surrounds is opposite to be slided, and such situation is very stable to the transmission of pull handle 21 and pull rod 23, phase
The service life answered is also longer.
Cross bar 241 and the positioning pin 242 being plugged in cross bar 241 form pilot pin 24, and it is horizontal that hollow stent 2 offers accommodating
The through-hole that bar 241 passes through, optionally, 241 both ends of cross bar are erected on through-hole, as the movement cross bar 241 of pull rod 23 is handed over
That replaces is plugged in waist through hole 11 or limit hole 12, alternatively, as shown in this embodiment, hollow stent 2 is provided with and positions
The corresponding kidney slot of pin 242, the positioning pin 242 pass through inclined hole 231 and slidable connection in kidney slot.
It is made and being further described based on the present embodiment, whole T-shaped, 2 vertical portion of hollow stent of the hollow stent 2
It is set in housing 1, the 21 middle part activity of pull handle of a lateral arrangement is connected in hollow stent 2, and pull handle 21 protrudes into hollow stent 2
One end be fixedly connected with a pull rod 23 arranged vertically, 23 bottom of pull rod is provided with an inclined hole 231, can in inclined hole 231
Slidably connect a pilot pin 24, pilot pin 24 include across inclined hole 231 pin shaft and be connected to the cross bar at pin shaft both ends
241 and the kidney slot that is arranged on hollow stent 2, hollow stent 2 be additionally provided with two that accommodating 241 both ends of cross bar pass through it is logical
Hole, housing 1 be respectively arranged with waist through hole 11 and a column limit hole 12, institute on the two sides inner wall of the through-hole sliding contact
It states inclined hole 231 to tilt obliquely towards the side of limit hole 12, then when user needs to be promoted the height of armrest, need to only become
Gesture pull handle 21 moves upwards, then pull handle 21 drives pull rod 23 to move upwards, since the side of inclined hole 231 towards limit hole 12 is upward
Inclination, then inclined hole 231 is moved to the left pin shaft along kidney slot, to be cross bar 241 to left, the side grafting of cross bar 241
In waist through hole 11, user moves upwards while pulling pull handle 21,241 side of cross bar and 11 grafting of waist through hole and edge
Waist through hole 11 slides, and when bracket rises to the height of user's needs, user unclamps to the application in pull handle 21, resets bullet
Spring 22 to pull handle 21 generate elastic force, move downward pull handle 21 and return to original state, thus pull rod 23 also drive inclined hole 231 to
Under, inclined hole 231 translates cross bar 241 to 12 side of limit hole by the limitation of its profile, and cross bar 241 is towards the side of limit hole 12
With 12 grafting of limit hole, to keep hollow stent 2 and housing 1 fixed, similarly, when user needs to reduce the height of armrest
When, user need to only pull pull handle 21 and simultaneously to decline hollow stent 2, and it removes when reaching required position and exerts a force to pull handle 21,
Cross bar 241 is plugged in corresponding limit hole 12, and to reach the fixation to position, hollow stent 2 is T-shaped, reduces support height
Until the part of bracket lateral arrangement is abutted with 1 upper end of housing, armrest structure for chair reaches the extreme position of its decline, works as cross bar
241 towards the side of waist through hole 11 with the top of waist through hole 11 when abutting, and unclamps 21 cross bar 241 of pull handle and corresponding limit
12 grafting of hole, armrest structure for chair reaches the extreme position of its rising at this time.
Optionally, the shell that the housing 1 is oppositely arranged by two engages, alternatively, the housing 1 is integrally formed
Part.
Above embodiments are only to illustrate the technical solution of the utility model and are not intended to limit it, all without departing from this
Any modification of utility model spirit and scope or equivalent replacement should all cover the range in technical solutions of the utility model
It is interior.
