Radian face 201.The middle part of sliding surface 31 can also projection form the middle part sliding rail 311 for being parallel to sliding rail 12, connector
A wears groove 22 is equipped in 20 front end face, middle part sliding rail 311 may pass through wears groove 22, drive connector 20 in sliding on sliding surface 31
It moves, as shown in Fig. 2, rotation sliding shaft core 3 is further formed resistance to sliding in sliding slot 11, keeps spindle housing 2 sliding in sliding rail 12
It is easier to realize support when dynamic.It is equipped with an axis hole 32 in the front end of rotation sliding shaft core 3, is corresponded in the two sides of fixed frame 1
Axis hole position is equipped with location hole 13, and location hole 13 and axis hole 32 can be passed through by a positioning pin 321 and again determines rotation sliding shaft core 3
In fixed frame 1.A block 33 is formed in rotation 3 end of sliding shaft core, and block can be after the connector 20 to spindle housing 2
Side forms and keeps out, and the lower end of block 33 connects a spring 34, after the end that the lower end of spring 34 is resisted against fixed frame 1 is located at sliding slot
Side, in the lower end of fixed frame 1 settable one for the location hole 14 of placement spring 34.Spring 34 forms certain elasticity to block 33
Support can form certain buffering to the spindle housing 2 slided above rotation sliding shaft core 3.
In conjunction with shown in fig. 4 to fig. 6, a positioning hole 23, corresponding company in fixed frame 1 are additionally provided in the front end face of connector 20
What connector 20 slid forward is equipped with a spherical shaped elastomeric plunger 4 to 23 position of location hole in front end.The front end face of fixed frame 1 can
One perforation 15 of setting, spherical shaped elastomeric plunger 4 pass through the front that perforation 15 rear-inclineds support is located at rotation sliding shaft core 3.Work as connection
When first 20 drive spindle housing 2 slides onto downwards horizontal lying or leaning state, the bulb 41 of spherical shaped elastomeric plunger 4 can be in connector front end
Location hole 23 positions in location hole 23 when sliding onto front, so as to enable spindle housing 2 position.Conversely, needing to pull out spindle housing 2
When, it is only necessary to spindle housing 2 is moved backward, the location hole 23 of connector front end in bulb 41 after deviating from.
For convenience of the utility model cooperation in the use of shaft, as shown in Figure 5, Figure 7, the top of spindle housing 2 forms connection
Plate 24 is located at 20 rear side of connector, and connecting plate 24, which is connected in support frame 5, drives support frame 5 to rotate, and the two sides of fixed frame 1 are formed
Wing 16 is connected, connection wing 16 is connected on the main case 6 below support frame.Mounting hole 241 is equipped in connecting plate 24, even
It connects and is equipped with mounting hole 161 in wing 16, to facilitate installation.
When the utility model is used, the state in conjunction with shown in Fig. 4 to Fig. 7, fixed frame 1 is fixedly connected on main case 6, is turned
Pedestal 2 is fixedly connected on support frame 5, and spindle housing 2 is movable in the sliding slot 1 of fixed frame 1, and connector 20 limits in sliding rail 12
Sliding drives support frame 5 can be rotated.When spindle housing 2 slides in and out in sliding rail 12, table can be supported to by opening rear support frame 5
Face place host can with tilt angle, and F closing force resolves into F machine gravity+F it can be seen from the force analysis in Fig. 7
Resistance is supported, support is realized using the gravity of host machine itself when support frame 5 at this time works, makes 5 stress balance of support frame
Afterwards, firm support can be formed.And when needing to pack up support frame 5, as shown in figure 8, F closing force needed for spindle housing 2
F guide rail sliding force+F centripetal force can be resolved on arc guide rail, packed up support frame 5 and rotated to main case back, slide into
Spindle housing 2 is driven to slide onto horizontal lying or leaning state downwards to connector 20, the bulb 41 of spherical shaped elastomeric plunger 4 can be before connector
The location hole 23 at end positions in location hole 23 when sliding onto front, and spindle housing 2 is enabled to position.Certainly, the utility model
The connection structure of shaft is also applied in the support frame or support rod of other forms, is cooperated so as to support and pack up easier.
After adopting the above structure, its structure of the utility model is simple, can operate in support frame, by spindle housing in fixation
It is positioned after being slided in frame, so that support frame is formed support erected state, and be laid flat and pack up, it is easy to operate, it is easy to use.
The product form and style of above-described embodiment and schema and non-limiting the utility model, any technical field
The appropriate changes or modifications that those of ordinary skill does it all should be regarded as the patent category for not departing from the utility model.
