Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Fig. 1～Fig. 5, the present invention includes the arm assembly 1 that is obliquely installed and the frame 3 of link assembly 2 and link assembly 2 downsides, arm assembly 1 lower end is fixedly connected with by several securing members with link assembly 2 upper ends.Link assembly 2 comprises link housing 21 and rotating mechanism 22, link housing 21 comprises standpipe 211 and lower cross plate 212, standpipe 211 3 faces enclose recording quantity, lower cross plate 212 two ends are soldered with standpipe 211 both sides, lower end respectively, and 31 4 jiaos, frame top board is fixed on frame 3 tops by securing member respectively.Link assembly 2 is hinged with the frame top board 31 of frame 3 upsides by the retaining mechanism 4 being arranged between link housing 21 lower ends and frame top board 31.
Retaining mechanism 4 comprises set lever 41, inverted U-shaped plate 42, a pair of compression cam 43, support pad 44, link bolt 45 and array butterfly spring 46, set lever 41 adopts tube bending to make, its one end is through inverted U-shaped plate 42, a pair of compression cam 43 lays respectively at inverted U-shaped plate 42 both sides, and is fixedly connected with set lever 41 one end respectively.Inverted U-shaped plate 42 lower ends are fixed on link bolt 45 tops, array butterfly spring 46 is arranged between support pad 44 and transverse slat convex platform 43, set lever 41 other ends are bent upwards after passing across the vertical mounting hole 214 of link housing 21, convenient operation set lever 41.
The shift motion C of link bolt 45 equals to compress the poor of the major axis A of cam 43 and minor axis B.While guaranteeing retaining mechanism 4 locking, by support pad 44, push down array butterfly spring 46, make transverse slat convex platform 213 compress frame projection seat 311, thus locking arm assembly 1.
Frame top board 31 deviates from arm assembly 1 one end routs up rib 312, and when the arm assembly of the present embodiment 1 rotates+20 ° or-20 °, 212 1 jiaos of lower cross plates withstand on rib 312 inner sides of frame top board 31, and arm assembly 1 has turned to extreme position.Arm assembly 1 can be within the scope of+20 °～-20 ° arbitrarily angled stopping, be convenient to user and select as required.
Arm assembly 1 turn left or the method for operating of turning right identical, the arm assembly 1 of take is below turned right+20 ° and the course of work of the present invention is described as example.
On lift set lever 41, set lever 41 drives a pair of compression cam 43 being fixedly connected with it to rotate counterclockwise, compression cam 43 is pushed down support pad 44 from major axis A Directional Contour and is become minor axis B Directional Contour facing to support pad 44, under the effect of array butterfly spring 46 reset forces, the journey of dividing a word with a hyphen at the end of a line on link bolt 45 C, support pad 44 with on move and be resisted against on the profile that compresses cam 43 minor axis B directions, lower cross plate convex platform 213 and frame projection seat 311 disengage, arm assembly 1 release.Now, arm assembly 1 can be turned right to+20 ° to the right positions shown in Fig. 5.Then depress set lever 41, set lever 41 drives a pair of compression cam 43 being fixedly connected with it to clockwise rotate, link bolt 45 moves down stroke C, support pad 44 moves down thereupon, until forwarding the profile of major axis A direction to, compression cam 43 pushes down support pad 44, support pad 44 compressions that array butterfly spring 46 is moved down, and the elastic force of array butterfly spring 46 pressurizeds makes lower cross plate convex platform 213 compress frame projection seats 311, retaining mechanism 4 locking arm assemblies 1, arm assembly 1 can not rotate.
In addition to the implementation, the present invention can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of requirement of the present invention.
