Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: a kind of to explain and publicise convenient for the student-directed of folding shrinking Table, including bottom plate 1, external slot 2, support rod 3, first rotating shaft 4, adsorption magnet piece 5, sliding slot 6, bull stick 7, casing 8, runner 9, stretch Contracting bar 10, movable block 11, sliding block 12, the second shaft 13, slide bar 14, top plate 15, extension board 16, kerve 17, supporting block 18 and company Extension bar 19, the lower end surface of bottom plate 1 offers external slot 2, and support rod 3 is equipped between external slot 2, and the one of support rod 3 It is fixedly connected with first rotating shaft 4 between end and external slot 2, and on the other end edge of support rod 3 and the inner wall of external slot 2 It is embedded with adsorption magnet piece 5, sliding slot 6 is set to the edge of 1 upper surface of bottom plate, and is equipped at the top center of bottom plate 1 Bull stick 7, and fixed between bull stick 7 and bottom plate 1 by the installation of casing 8, and the end of bull stick 7 is coaxially connected with runner 9, stretches The upper and lower side of contracting bar 10 has been respectively fixedly connected with movable block 11 and sliding block 12, and the company of telescopic rod 10 and movable block 11 and sliding block 12 The place of connecing is provided with the second shaft 13, and movable block 11 is installed on the bottom of top plate 15, the top of top plate 15 by slide bar 14 Edge is hinged with extension board 16, and kerve 17 is offered on extension board 16, and the lower end surface edge of top plate 15 is equipped with Supporting block 18 is connected with each other between sliding block 12 by connecting rod 19, and the middle part of connecting rod 19 and bull stick 7 are through connection；

The relative dislocation in external slot 2 of support rod 3 is provided with 2, and support rod 3 is set as " n " font structure, and props up Connection is adsorbed between strut 3 and external slot 2, the setting of support rod 3, it is convenient to save in storage, after deployment can be to bottom plate 1 Mounting height is supported change, to facilitate the adjusting of its height installation and volume size；

The end of bull stick 7 is set as " T " font structure, and the outer wall of bull stick 7 is set as double section thread-like structures, and turns Double section screw threads trend on bar 7 is on the contrary, bull stick 7 and connecting rod 19 are perforative screw connection structure, " T " word of bull stick 7 simultaneously Type setting prevents it from installing unstability and falls off, while the thread-like structure on the outside of it is rotated by it so that connecting rod 19 with Sliding block 12 makes the mobile change in position, to realize that manually the spacing between top plate 15 and bottom plate 1 changes；

Extension board 16 is symmetrically arranged with 2 about the central transverse axis of top plate 15, and the docking length and width of extension board 16 with The length and width of top plate 15 are equal, and are opposite overturning structure between extension board 16 and top plate 15, and the work use of extension board 16 adds Add, placed side where 15 top of top plate can be subjected to expansion expansion after deployment；

Supporting block 18 and top plate 15 constitute the structure that is slidably installed of engaging, and the overhanging roof of supporting block 18 and extension board 16 Top be bonded to each other, the use that is slidably installed of supporting block 18 carries out Auxiliary support to the avris of extension board 16 after removal, keeps away Exempt from stress overturning damage after extension board 16 is unfolded.

Working principle: when explaining and publicising table using this convenient for the student-directed of folding shrinking, first according to Fig. 1-2, to bottom plate 1 Installation fixed height when being changed, by the rotary action of first rotating shaft 4, by support rod 3 from the external of 1 lower end surface of bottom plate It is taken out in slot 2, under the turning-over support effect of support rod 3, change is fixed to the mounting height of bottom plate 1, it is easy to operate fast Victory, while in the case where needing to carry out storage preservation to support rod 3, the absorption connection function of adsorption magnet piece 5 can be avoided effectively Problem is fallen after the installation of support rod 3；

According to Fig. 1-3, when needing to be changed the relative spacing between bottom plate 1 and top plate 15, by can be manually rotated Runner 9, runner 9 directly rotate in the casing 8 at 1 top of bottom plate with bull stick 7, double section screw threads and company due to 7 outside of bull stick Extension bar 19 is connected with each other, so that bull stick 7 can make two connecting rods 19 do relative motion in the course of rotation, due to connecting rod 19 end is fixedly connected with sliding block 12, so that sliding block 12 slides in the sliding slot 6 at 1 top of bottom plate, so that " X " on sliding block 12 Relative telescopic occurs for font telescopic rod 10, and end is slided on slide bar 14 by movable block 11, thus while its variation Change the relative spacing between bottom plate 1 and top plate 15, realization facilitates its folding shrinking while explaining and publicising table Level Change；

According to Fig. 1 and Fig. 4, the desktop length for explaining and publicising table is carried out by the opposite overturning between extension board 16 and top plate 15 Change, be easy to use, while the setting of supporting block 18, slide and take out from the bottom margin of top plate 15, to extension board 16 and top Junction between plate 15 is supported fixation, avoids extension board 16 that stress deflection occurs at work and damages.

Although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art Say, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic into Row equivalent replacement, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all It is included within the scope of protection of this utility model.
