Abstract

The utility model relates to a movable supporting means which is characterized in that a groove-shaped contracted slider which can be slid in a groove is embedded in an upper support plate, and a chute is arranged on the slider. A sliding pin which is fixed with the upper support plate is arranged in the chute, and a square elbow of 90 DEG is connected with the lower side of the upper support plate which is definite distance away from the front of the sliding pin. A small tension spring is arranged between the square elbow and the sliding pin, and a side wall of the rear part of the contracted slider is a little higher than the side wall of the upper support plate, and is provided with a bevel edge for transition. A notch is arranged at the side wall of the upper support plate arranged correspondingly to the bevel edge of the contracted slider, and a main tension spring is arranged between the middle of a bearing rod and the rear part of the upper support plate. The movable supporting means has the advantages of convenience, rapidness, safety, compactness and concealment.

Description

Travel(l)ing rest

It is the cabinet of feature that the utility model relates in to regulate shelf or dividing plate, frame or shelf assembly, and especially a kind of foldable travel(l)ing rest can be widely used in small space, as table, shelf etc. are set.

People can run in narrow space unavoidably and handle official business, as write or place some office appliances, if do some fixing desks or shelf then take up space very much, have influence on people's scope of activities, so just expected retractable table or shelf, the time spent does not just accept at ordinary times, opens when needing again.But seldom having ready-made Folding device to sell on the market, generally all is that the person of needs finds out some structures temporarily, all has shortcoming aspect function, easy to use, safety and stability and the outward appearance.

The purpose of this utility model just provides a kind of travel(l)ing rest of producing in batches, it with table with can open and draw in easily and fast after wall is connected, and safe and reliable, misoperation can not occur and injure the person, run into collision and also can not cave in.

The technical scheme that realizes the purpose of the utility model is: this travel(l)ing rest contains the last supporting spring of channel-section steel shape, perpendicular supporting spring and pole, hold-down screw, last supporting spring and perpendicular supporting spring upper end are used rivet and are connected and leave certain interval, be connected with two following rivets between pole and the perpendicular supporting spring, its design feature is to go up the embedded flute profile that can slide of adorning of supporting spring to shrink slide block in groove, have chute on the slide block, be equipped with in it and the fixing sliding pin of last supporting spring, connect one under the last supporting spring of a distance, sliding pin the place ahead and be 90 ° straight elbow, between straight elbow and the sliding pin small extension spring is housed, the rear sidewall of shrinking slide block slightly exceeds last supporting spring sidewall and the hypotenuse transition is arranged, corresponding to shrink slide block hypotenuse place on the supporting spring sidewall have notch, main extension spring is equipped with the rear portion of last supporting spring in the pole middle part.

The front end of contraction slide block described in the utility model is provided with handle.Between described sliding pin and the chute pad is housed.The notch below that described upward supporting spring is offered has barb.

Advantage and good effect that the utility model is compared with prior art had are: this travel(l)ing rest can be used as a product lot quantity production, the independent sale, the user can use itself and table and metope after fixing with hold-down screw, the table that connects with this support can be very convenient, open fast and draw in, also very safe and reliable in operating process, misoperation can not take place as jamming a finger etc., suffer to collide and can not cave in suddenly, volume is small and exquisite, hidden.

To and contrast accompanying drawing by embodiment below is described specifically structure of the present utility model and operation principle:

Fig. 1 is the utility model structure chart in use.

Fig. 2 is the front view of the utility model when opening.

Fig. 3 is the vertical view of the utility model when collapsing.

Fig. 4 is the utility model front view that time band analyses and observe that collapses.

Fig. 5 is the front view of the utility model when collapsing.

Fig. 6 is that the utility model collapses to the structure chart of a half.

As shown in the figure, present embodiment is by last supporting spring 1, contraction slide block 2, small extension spring 3, sliding pin 4, pad 5, hold-down screw 6, pole 7, main extension spring 8, time rivet 9, last rivet 10 and perpendicular supporting spring 11, except that securing member and extension spring, above-mentioned part all adopts the channel-section steel structure.

It is hinged that the last supporting spring 1 of level and vertical perpendicular supporting spring 11 are used rivet 10, the middle part of pole 7 and perpendicular supporting spring with about two following rivets 9 hinged, the middle part of pole with link to each other with main extension spring 8 after stay hook is gone out at the rear portion of last supporting spring.Setting-in shrinks slide block 2 in the groove of last supporting spring 1, the two side of slide block is a little less than the sidewall of last supporting spring 1, the rear sidewall of slide block then slightly exceeds the sidewall of going up supporting spring 1, between by hypotenuse 2-4 transition, that shrinks slide block is shaped on handle 2-1 foremost, the middle part of slide block has chute 2-2, there is sliding pin 4 and the pad 5 that is fixed on the supporting spring top at place, centre position at chute, sliding pin can replace with rivet, and straight elbow 2-3 is gone out in a distance, sliding pin the place ahead, has drawn small extension spring 3 between straight elbow and the sliding pin.Have notch 1-1 corresponding to the hypotenuse 2-4 place of shrinking slide block 2 on the sidewall of last supporting spring 1, the below of notch is provided with barb 1-2.3 hold-down screws of last supporting spring 1 usefulness 6 are fixing with table 12, perpendicular 3 hold-down screws 6 of supporting spring 11 usefulness and wall mounted.

Open mode of the present utility model as shown in Figure 2, the notch 1-1 of supporting spring 1 is withstood in the upper end of pole 7, the barb 1-2 of notch below plays safety effect, small extension spring 3 and main extension spring 8 are free state.

During gathering, as shown in Figure 6, table 12 is lifted slightly, make pole 7 tops throw off the notch barb of going up supporting spring, outwards pull shrinks slide block 2, the higher sidewall in contraction slide block rear portion is mended removed notch 1-1, the hypotenuse 2-4 of slide block forces pole to break away from notch simultaneously, presses down table, and last supporting spring can rotate around last rivet 10 smoothly, main extension spring 8 is stressed, when having served as, spring into fast in the groove of perpendicular supporting spring 11, when collapsing fully to extreme position, straight elbow 2-3 catches on the back side, pole 7 upper end, shown in Fig. 3～5.

When opening, on lift table, the straight elbow 2-3 of slide block take advantage of a situation will be on the pole 7 band, as long as turn over certain angle, under the effect of main extension spring 8 convergent forces, support all flicks, notch is withstood in the upper end of pole, finishes and opens.
