Abstract
The utility model relates to a learning apparatus suitable for primary and secondary school students, particularly a folding eyesight stand. The utility model is mainly composed of a base, a support rod, and a transverse blocking rod. The bottom of the base is provided with a fixed and positioned acetabula, the front end of the base is hinged with the support rod with a locked device so as to cause the support rod to vertically rotate to form a certain angle with the base, and the other end of the support rod is hinged with the transver blocking rod which can rotate horizontally. The folding eyesight stand has the advantages of reasonable organizational design, simple operation, and convenient carrying, and can cause primary and secondary school students to maintain a sitting posture and a distance for viewing objects.
Description
This utility model relates to a kind of students in middle and primary schools' of being suitable for schooling apparatus, particularly a kind of folding vision frame.
We know, because shortage eye hygiene knowledge, and self constrainting ability is relatively poor relatively, the students in middle and primary schools of China are when reading and writing, the amblyopia phenomenon that is caused by incorrect sitting-pose is more and more serious, as can not in time correctly guiding, certainly will cause even more serious consequence.
The purpose of this utility model be to provide a kind of mechanism design made students in middle and primary schools reasonable, simple to operate, easy to carry to keep good sitting position and look object distance from collapsible vision frame.
For achieving the above object, folding vision frame of the present utility model is made up of base, pole, transverse blocking-rod, and the bottom of base is provided with surely sucker admittedly, the hinged pole of deciding device with lock of base front end, and pole top axle connects a transverse blocking-rod.
The base front end is provided with the folding stable support bar that axle connects, and the gear slide plate that stable support bar one end is provided with the band groove combines with the elastic positioning pin of base, and stable support bar bottom is provided with sucker; Base rear end can be provided with and the contacted collapsible postive stop baffle in table limit.
The inner socket telescopic arm of pole, pole and telescopic arm are located by tooth bar; The locking device of pole and base can be that base is provided with positioning ratchet wheel, and pole has the manual elastic pawl that is meshed with positioning ratchet wheel.
The transverse blocking-rod end can be provided with baffle head, baffle head and transverse blocking-rod spiral marking connection.
Characteristics of the present utility model are: reasonable in design, simple to operate, easy to carry, and students in middle and primary schools' correct read-write posture can be kept effectively, and the requirement of user can be satisfied preferably.
Below in conjunction with description of drawings embodiment:
Fig. 1 is the sketch map of a kind of embodiment of the present utility model
Fig. 2 is a Retchet gear type locking device sketch map
Fig. 3 is the base upward view
Fig. 4 is a folding back overall schematic
A kind of folding vision frame, by base 1, pole 2, transverse blocking-rod 3 is formed, the bottom of base 1 is provided with surely sucker 4 admittedly, surely sucker 4 is installed on the sucker disk seat 17 admittedly, base 1 front end hinged one pole 2 of deciding device with lock, pole 2 can vertically be rotated, have a certain degree with base 1 shape, the hinged transverse blocking-rod 3 of the pole 2 top other ends, transverse blocking-rod 3 can horizontally rotate, and base 1 front end is provided with the folding stable support bar 5 that axle connects, and stable support bar 5 one ends are provided with the gear slide plate 6 of band groove, gear slide plate 6 combines with the elastic positioning pin 7 of base 1, along with the switching of stable support bar 5, elastic positioning pin 7 will play locking action to it, and stable support bar 5 bottoms can be provided with sucker 4, sucker 4 can be installed on the collapsible sucker disk seat 14, and base 1 rear end can be provided with and the contacted collapsible postive stop baffle 8 in table limit.
Transverse blocking-rod 3 is articulated in an end of pole 2, and can rotary folding to flat by positions with pole 2, by the jump ring 13 that pole 2 is provided with that transverse blocking-rod 3 is fixing, transverse blocking-rod 3 ends can be provided with baffle head 16, baffle head 16 adopts spiral marking connection with transverse blocking-rod 3, and can adjust the collapsing length and the anglec of rotation of baffle head 16.
Using method of the present utility model is: sucker is installed on the corresponding sucker disk seat, launch the stable support bar, sucker disk seat on it is kept flat, and base is fixing on the table, rotation pole, adjust to suitable angle, launch transverse blocking-rod, make its retaining, adjust its length at the user head, pull out telescopic arm, adjust its length and after suitable distance, can use.With after when turning up, press the manual elasticity teeth on the pole earlier, telescopic arm is pushed back, folding transverse blocking-rod is pressed pole again and is gone up elastic pawl to closing up with pole, pushes pole and is closed on the base, and from desktop, this utility model is taken off, folding stable support bar and base close up and get final product.
