Abstract

A picture suspender convenient for installation belongs to a school education appliance and comprises a horizontal air track, a longitudinal connecting rod which is suspended on the horizontal air track and at the front side of a blackboard, a lifting rod that is directly or indirectly connected with the longitudinal connecting rod and can do up-and-down movement relatively, and a picture rod which is connected with the lifting rod and used for hanging-placing a paper picture, wherein the end parts of the horizontal air track are indirectly connected with the front ends of two cantilevers by injection-molding plug connectors; and the rear ends of the two cantilevers are fixed on the wall surface over the blackboard. The picture suspender is reasonable in stress; the injection-molding plug connector leads the cantilevers to be easy for being connected with the horizontal air track, and is beneficial to keeping the shape of the horizontal air track for long time; and vision near the connection part is very concise.

Description

The wall chart device of being convenient to install

Technical field

The utility model relates to the daily teaching appliance of a kind of middle and primary schools, promptly is convenient to the wall chart device of installing.

Background technology

For many years, Chinese patent discloses the many designs that are the theme with the wall chart device, they generally can both finish the wall chart task, but all improve inadequately and optimization, what wherein have the more outstanding pattern of dealing with problems is Chinese patent 200620046025.6 (portable blackboard hanger, patentee: Shanghai Shangyin Yangpu School, designer: encourage and goodly ooze).ZL200620046025.6 this application purpose be make things convenient for paper figure (hanger) move and assembly and disassembly convenient in order to avoid too much block blackboard panel, specifically it comprises first track that is fixedly arranged on the blackboard avris, combines with first track and has sliding part of second track or the like.The design of this wall chart device does not see on a large scale as yet and applies that its patent document is not also addressed the concrete mounting structure of wall chart device.

In a lot of hospitals, a kind of movable fixture of suspension type Infusion support is mounted on horizontal guide rail by roller, and the upper side of horizontal guide rail directly is pinned to the ward end face directly over the sick bed, thereby realizes integral installation.

Summary of the invention

The utility model purpose provides a kind of wall chart device of being convenient to install, and the paper figure that this wall chart device is used for imparting knowledge to students in real time in the middle and primary schools classroom hangs up.

Technical solutions of the utility model: a kind of wall chart device of being convenient to install comprises the empty rail of level, is mounted on the empty rail of level and is positioned at the vertical connecting rod, connected directly or indirectly with vertical connecting rod and can make the relative elevating lever that moves up and down, be connected in the figure bar that is used to hang up paper figure of elevating lever of blackboard front side by roller, wherein: each is connected with the front end of a cantilever the empty rail left end of level with right-hand member, the contour metope that is fixed in the blackboard top in the rear end of two cantilevers.

In such scheme, the front end of cantilever can be connected by 1 injection moulding plug connector indirectly with the empty rail of level end.

The utility model is special have been realized better docking with cantilever owing to used the injection moulding connector on the one hand, is also effectively suppressing the deformation tendency in long-term use of the empty rail of level on the other hand.The stressed arrangement of the utility model is reasonable, and near the vision the empty rail end of the level place is also quite succinct.

The specific embodiment

Embodiment 1.Referring to Fig. 3, Fig. 4, Fig. 5, the wall chart device of being convenient to install comprises the empty rail 1 of level, is mounted on the empty rail 1 of level and is positioned at the vertical connecting rod 2 of blackboard 8 front sides by roller, elevating lever 3 is dynamically connected with vertical connecting rod 2 and can does relative moving up and down, the figure bar 5 that is used to hang up paper figure is connected in the upper end of elevating lever 3, the front end of cantilever 6 insert the empty rail 1 end inner chamber of level and on supporting the inner underside of empty rail 1 end face of level, with the leading flank of the empty rail 1 of screw fixing horizontal and the front end face 7 of cantilever 6.

Embodiment 2, referring to Fig. 6--and Figure 10.With the injection moulding plug connector is the empty rail 1 of intermediary realization level and being connected of cantilever 6.Wherein, the end tight fit of the empty rail 1 of level is inserted the interlayer 9 of injection moulding plug connector, and the front end tight fit of cantilever 6 is inserted the center cavity 10 of injection moulding plug connector.Because the injection moulding plug connector, helps the prevention of water distortion tendency of rail 1 out of the void for the accurate flexible clamping in the interior outside of the empty rail 1 of level, has also reduced vibrations and noise in the product use.Surplus with example 1.The audio-visual picture of injection moulding plug connector is referring to Fig. 6 and Fig. 7.

Also what deserves to be explained is about the design:

1, compares with the accompanying drawing that this case is provided, stablize under the prerequisite of docking with the empty rail of level 1 end, can allow some concrete variation of shape of cantilever 6 front ends in assurance.The length of cantilever 6 is regulated corresponding to blackboard 8 thickness.The material of cantilever 6 can be the stainless steel of exempting from outer list processing.

2, referring to Figure 11, Figure 12, Figure 13.When the empty rail of level 1 is long, when for example being equivalent to half blackboard 8 length even reaching blackboard 8 total lengths (about 4 meters), consider that again the operation when using product is stressed, the stage casing of the empty rail 1 of level has the tendency of tenesmus.For this reason, make paster 11 fixing (as being that the seccotine cementation is fixed), do not produce tenesmus to guarantee the empty rail 1 of level by the part 12 of choosing that is fixed in metope in the middle part of the empty rail 1 of level.

The stable maintenance of 3, the stable maintenance of elevating lever 3 and vertical connecting rod 2 mode connected directly or indirectly, elevating lever 3 and vertical connecting rod 2 full closed states, elevating lever 3 and vertical connecting rod 2 greatest separation, their concrete structure mode is seen Chinese patent case " succinctly wall chart device ", " the wall chart device that contains locking device ".

Claims (2)

1. wall chart device of being convenient to install, it comprises the empty rail of level, is mounted on the vertical connecting rod, connected directly or indirectly with vertical connecting rod and can make the relative elevating lever that moves up and down, be connected in the figure bar that hangs up paper figure of elevating lever of the empty rail of level by roller, it is characterized in that: each is connected with the front end of a cantilever the empty rail left end of level with right-hand member, the contour metope that is fixed in the blackboard top in the rear end of two cantilevers.

2. the wall chart device of being convenient to install according to claim 1 is characterized in that: the cantilever front end is connected by the injection moulding plug connector indirectly with the empty rail of level end.
