Description
Technical field
The present invention relates to a kind of crutch, and more specifically it is related to a kind of safety crutch suitable for old man.
Background technique
Office, Working Committee, national old-age group has issued " Chinese population aging prediction of the development trend research report " and has referred to
Out, 21 century is the epoch of aging of population.China entered aging society in 1999, was the relatively early hair for entering aging society
One of country in exhibition will be elderly population are most in the world country.With the increase of social survival pressure and living cost, year
Lepton female accompanies and attends to will be reduced the time at one's side in parent by continuous compression.Therefore peace of the elderly during going out alone
How to obtain effectively ensureing one that is to put in face of in the whole society the problem of meriting attention entirely.Crutch is that old man passes through when outgoing
The tool being often used.Traditional crutch includes the body of rod and the handle set on rod end, and the end of the body of rod is equipped with anti-skidding
Rubber pad.But rubber pad can only play the role of in cement floor and ceramic tile bottom surface it is anti-skidding, and in wet and slippery muddy ground, rubber pad
Antiskid effect it is poor.Therefore, it is urgent to provide a kind of crutch, so as to solve the deficiencies in the prior art.
Summary of the invention
In view of the deficienciess of the prior art, there is knot the invention reside in a kind of safety crutch suitable for old man is provided
Structure is stablized, can easy manipulation change the contact area on crutch and ground, enhancing security performance, the effect of adjustable crutch length.
To achieve the above object, the present invention provides the following technical scheme that a kind of safety crutch suitable for old man, including
Contractile crutch bar and it is set to support handle of the crutch bar one end with control button；It is characterized by: the crutch bar
The other end is provided with fixing seat；It is arranged with disk on crutch bar above the fixing seat, disk under external force can be along turning
Stick stem axial direction is mobile；Several connecting rods are connected on the outside of the disk；Described connecting rod one end is connected to disk
Upper and opposed discs are swung；The connecting rod other end is connected with gripper jaw；The gripper jaw is flexibly connected with fixing seat,
The relatively fixed seat of gripper jaw is with gripper jaw middle part for axis swing；When disk is moved along crutch bar axial direction, connection is driven
Bar moves up and down that gripper jaw is driven to swing, and realizes closing up, separating between gripper jaw.
By using above-mentioned technical proposal, when disk is when the effect of external force moves up, pulling connecting rod is moved up,
To drive one end of gripper jaw to move up, the other end is moved down, to realize closing up for several gripper jaws；Work as disk
When moving down, connecting rod, the direction of motion of gripper jaw and the above-mentioned direction of motion are on the contrary, to realize dividing for several gripper jaws
From.The effect of such structure setting can change the contact area on crutch and ground, in old man in use, can be improved safety
Property, and old man's waist is not flexible, can by closing up between gripper jaw, separate, crawl is realized to the article of underground, thus
Reduction is bent over, and this is acted.
The present invention is further arranged to: the connecting rod is uniformly separated along disk external circumferential；Setting above the disk
There is connector sleeve, connector sleeve can equally be moved along the axial direction of crutch bar；The connector sleeve is equipped with far from one end of disk along it
Axially open up to several elastic force slots in disk direction；The connector sleeve end thread is connected with pullover；The pullover lower end to
Upper end orient diameter is gradually reduced, to tighten during threaded connection to connector sleeve.
Made between several elastic force slots by using above-mentioned technical proposal by the threaded connection of pullover and connector sleeve
Distance becomes smaller, to tighten to connector sleeve, is close to connector sleeve inner wall with crutch bar, so that disk, connector sleeve are fixed,
Prevent disk, connector sleeve from moving up and down, so that closing up between gripper jaw or isolated state are fixed.
The present invention is further arranged to: being set as hollow inside the crutch bar；It is symmetrical arranged on the crutch bar side wall
There are two shifting chutes；The driving mechanism is arranged in crutch bar, includes motor, screw rod and nut, the nut can edge
Crutch bar axial direction is mobile；Mobile connection stick is fixedly installed on the nut；The mobile connection stick passes through shifting chute and company
Female connector is fixedly connected, and can be moved in shifting chute；The nut thread is connected with screw rod；The screw rod, which is connected to the motor, to be connect,
And it rotates driven by the motor.
By using above-mentioned technical proposal, nut, screw rod, motor collectively constitute a leading screw and nut mechanism, when motor band
In the case where dynamic screw rod rotation, because nut is limited by shifting chute, it can only be moved up and down along the axial direction of screw rod, because of spiral shell
It is connected between female and connector sleeve by mobile connection stick, so nut moves up and down, is able to drive connector sleeve and disk or more
It is mobile.
The present invention is further arranged to: the crutch bar includes the first crutch bar and the second crutch bar；The fixation
Seat is fixed on the second crutch boom end；The second crutch bar is far from being provided with elastic button on one end side wall of fixing seat；Institute
It states and offers several limit holes being adapted to elastic button on the first crutch bar side wall；By changing elastic button and limit hole
Relative position to realizing the scalable of crutch bar.
The present invention is further arranged to: being fixedly installed fixed block on the motor；The fixed block two sides fixed setting
There is cylindrical pillar to be fixedly connected with the side wall in the second crutch bar.
By using above-mentioned technical proposal, motor, which is fixed, will not generate disengaging.
The present invention is further arranged to: there are two non-slipping blocks for one end setting of the gripper jaw far from connecting rod: setting respectively
It is placed on gripper jaw end and side wall.
By using above-mentioned technical proposal, non-slipping block on gripper jaw side wall, when gripper jaw closes up, on side wall
Non-slipping block abuts against each other, the non-slipping block and ground face contact of end.
In conclusion the invention has the following advantages: driving changing for the state of gripper jaw by feed screw nut's structure
Become, the contact area on crutch bar and ground can be changed, to prevent from falling down, and old man's waist is not flexible, folder can be passed through
Closing up, separating between pawl is held, crawl is realized to the article of underground, to reduce this movement of bending over, the product of the application makes
With convenience, power supply is set in crutch bar, and controls the starting of motor by power switch and rotates forward and invert, to realize spiral shell
Mother moves up and down, and then changes the state of gripper jaw.
