Abstract
The utility model discloses a switch-over frame device with multiple freedom degrees and comprises an arm rod, a shaft section, a locking device, an upper joint and a lower joint. The shaft section is an orthogonal rotary shaft section with two freedom degrees and is composed of two rotating shaft sections. The two orthogonal rotary shaft sections are connected together in series by the arm rod between the sections, and the rotating shaft sections are connected by an inner and an outer cylindrical gears which are engaged mutually. Higher pairs of the device are connected by lower pairs in series, and the self body has four freedom degrees. The utility model has the advantages of artful and compact structure, and flexible and convenient use and can be used for being matched with various seat frames.
Description
The utility model relates to support, particularly a kind of multivariant Change-over frame device that the orientation is regulated that can be used for.
Can satisfy the mechanical device of multi-faceted adjusting, the most frequently used working as is the ball bearing of tight device with lock.Its bearing block and pedestal are fixed, axostylus axostyle be supported thing and connect.In addition just like the structure of flexible fluorescent tube.But they all have a defect, locking poor performance that Here it is, stability is not enough, can't support bigger head support weight, thus remove the light lotus of application as on desk lamp one series products, rarely have utilization.
The purpose of this utility model is to provide a kind of Universal arm device, and it is no less than four frees degree, can go up the manual type mechanical locking of position, implementation space in any direction, and can bear enough loads.
Design philosophy of the present utility model adds the series connection that the compression spring effect realizes clutch and locking and kinematic pair based on the full engagement of inside and outside cylinder tooth, reaches the variation from the lower pair to the higher pair.
Universal arm device of the present utility model, comprise armed lever, joint, locking device and last lower contact, it is characterized in that said joint is the revolution joint, form binary quadrature by two revolution joints and rotate joint, the axis normal of two revolution joints, two quadrature turning cylinder internodes by armed lever through being coupled together in series, the connection of revolution joint is made of the inside and outside circle stud wheel of full engagement mutually, be separately positioned on the housing mutual rotation, that install with one heart and housing and armed lever on, have locking to be connected in series therebetween with stage clip, gear shaft and axle head securing member.
Be provided with axocoel in the said gear shaft, built-in stage clip, sliding dress outer cylinder gear cover on the axle, spacing by bearing pin, stage clip acts on one side of bearing pin, and another side is provided with a push rod that is used for manual clutch.
Also be provided with in the said joint and keep gear tooth clutch state locking device.
Said armed lever also is provided with extension bar and/or chain lock.
Good effect of the present utility model is:
1, adopt the kinematic pair series connection can make designs simplification, the step-down pair is a higher pair, increases the free degree.
2, have and be no less than four frees degree, so can satisfy general space orientation requirement.
3, owing to use mechanical caging and inside and outside gears engaged, good stability, bearing capacity is strong.
4, product structure exquisiteness, good looking appearance is convenient to connect annex, and is easy to install, applicable surface
Extensively.
5, add that dismounting is convenient, helps utilizing field condition to be advanced after chain lock and the switching annex
Fixing and the satisfied needs that carry of row.
Be illustrated below in conjunction with embodiment and accompanying drawing thereof.
Referring to accompanying drawing.From embodiment shown in Figure 1 as can be known, the Universal arm device is mainly by armed lever, two joints 3 that quadrature rotates
1, 3
2Form, external usefulness is made in top connection 4, lower contact 1 usefulness that fixes.Extension bar 2 is used for spreading.The 5th, the lock core of chain lock, by lock core can make connection between top connection and the joint 3 realize in conjunction with or separate.This lock core can be arranged on any end, on the armed lever in the middle of also can being located at.Loading and unloading are quick, are convenient to carry.In addition, last lower contact can be selected different structures, cooperates annex for external use.
Shown in Figure 2 is the joint unit that a quadrature rotates.Seen level and vertical both direction rotational freedom from drawing, two quadratures have been rotated the joint series connection just can constitute four frees degree.Be provided with roller gear in a section in the housing 6, the gear teeth 11 of outer cylinder gear cover are engaged with, cylindrical geared sleeve cunning is contained on the gear shaft 8, the gear teeth 9 engagement of the interior roller gear section in front end and the housing 7, slide by it and to put in place (when throw off at that time with housing 6 on during the getting in touch of internal gear section) realize separating.Can relatively rotate when separating.During the cross-over connection of the outer cylinder gear gear teeth branch is located at that the roller gear gear teeth are combined into one in two sections on the housing 6,7.The below of figure middle shell 6 also is combined with another group outer cylinder gear 22, it is meshed with interior roller gear 23, and the arm pipe by roller gear 23 in the pulling setting-in slides along axostylus axostyle 24 compression press springs 26, its gear teeth meshing is separated from, and walks around moving at manual active force backspin.One looses one's grip can mesh location (being equivalent to locking) again under the effect of stage clip 26.The 27th, packing ring, the 28th, hold-down screw.The 25th, armed lever, the outside is with an ornamental pretective sleeve pipe.Also be provided with the locked component device that a clutch is used in the housing 6.Specifically it comprises fixedly a block set 20 and a movable cutting ferrule 17.The 16th, a positioning convex on the cutting ferrule is the engages fixed state when its orientation is positioned at elongated slot 15; When it was positioned at shallow slot 21, the roller gear gear teeth maintained the state of freeing in push rod 18 made on the housing 6, and 6,7 of housings can relatively rotate arbitrarily.The 19th, recover spring, make movable cutting ferrule 17, push rod 18 retreat and withdraw from gear teeth meshing fixedly the time.Be positioned at axocoel and make the stage clip 10 and gear shaft 8 serial connections of locking usefulness, act on the bearing pin 12 another side drawn stem 18 overheads and control.12 are the padding pad, the 13rd, and the stationary positioned nut is serially connected gear shaft 8 and housing 6,7 by the interior roller gear end face on the housing 6.
