Description

A kind of foldable portable table

Technical field

The utility model is specifically related to a kind of folding portable desk.

Background technology

The dormitory generally all provides two-berth lodging condition, for example in the university student dormitory, the student who is in the upper berth when the upper berth the space that can utilize limited, the space that can place books or article is also limited.

At present, provide a kind of folding table on the market, four table legs can be amounted to; In use, table leg is opened, when not using; Table leg is closed up, and such Foldable table has been saved the space to a certain extent, provides convenience in the confined space, using.But this folding table can not get out easily for a long time, if get out for a long time, can impact student's activity space.

Summary of the invention

The purpose of the utility model is limited in order to solve present student spendable space in the dormitory, and common Foldable table inconvenience gets out the problem of use for a long time, proposes a kind of new foldable portable table.

A kind of foldable portable table that the utility model proposes comprises desktop and two supports of a rectangle, and the back fixation of desktop has two bearings, has the hole on the bearing, and the upper end of support has the hole, adopts hand tighten screw to be connected with bearing with the upper end of nut with support; The edge at the back of desktop also is provided with first clamp; The lower end of support has horizontal stand, has the hole on the horizontal stand; Between the sheer pole of upper berth guardrail and bed board, be fixed with the corner bracket at 90 degree right angles, a side that is positioned at horizontal level on the corner bracket has a round, adopts hand tighten screw to be connected with corner bracket with the horizontal stand of nut with the lower end of support; Two bearings are about relative two limit A of desktop and the middle separated time C left-right symmetric of B; Described first clamp is about relative two limit A of desktop and the middle separated time C left-right symmetric of B.

The advantage and the good effect of the utility model are: the student to the upper berth, dormitory for it provides a kind of desk easily, and can get out for a long time, and can not have influence on normal usage space; Easy to use, can folding and retraction obsolete the time, conserve space; Simple in structure, be convenient to produce in batches, have practicality.

The specific embodiment

To combine accompanying drawing and embodiment that the utility model is done further to specify below.

As shown in Figure 1, be the foldable portable table of the utility model, comprise a rectangle desktop 1 and two supports 2.Back fixation at desktop 1 has two bearings 3, fixes two supports 2 through bearing 3.Desktop 1 is fixed on through first clamp 4 on the cross tube 11 of guardrail, and support 2 is fixed on the corner bracket 6, and corner bracket 6 is fixed on the sheer pole 12 of bed board and guardrail.

As shown in Figure 2, establish A, B and be two relative limits of desktop 1, C is the middle separated time of limit A and B.Back, limit A at desktop 1 are fixed with first clamp 4 respectively about the symmetrical position of line C.Because, the two-berth in the dormitory, the set guardrail in upper berth generally adopts material manufacturings such as iron pipe or stainless steel tube, so the chuck of first clamp 4 is the semicircular cylinder shape.And the direction of the opening of first clamp 4 B towards the limit is just towards the inboard at desktop 1 back.At the back of

desktop

1,3, two bearings 3 of two bearings are arranged about line C left-right symmetric near the fixed-site of limit B.

As shown in Figure 3, have the hole on the bearing 3, the upper end of support 2 also has the hole, and the hole is used to assemble hand tighten screw and hand nutting.Adopt hand tighten screw that support 2 upper ends are connected with bearing 3, after adjusting desktop 1 and support 2, tighten the hand nutting, fixed support 2 and desktop 1 are kept at an angle desktop 1 and support 2.When not tightening the hand nutting, support 2 can rotate around bearing 3 flexibly.

As shown in Figure 4, the lower end of support 2 has horizontal stand 5, has the hole on the horizontal stand 5, is used for being connected corner bracket 6 through hand tighten screw with the hand nutting.

As shown in Figure 5, corner bracket 6 has 90 degree right angles, adopts iron plate or stainless steel substrates manufacturing, on the sheet of a side, has a round, is 3 holes among Fig. 5.When portable desk is installed, corner bracket to be put into the space of bed board and guardrail sheer pole 12, and corner bracket 6 and bed board are fixed through filler, the side that corner bracket 6 has the hole is positioned at horizontal direction.After desktop 1 being fixed on above the guardrail on the cross bar 11; According to the height of guardrail, select suitable hole in the corner bracket 6, make desktop 1 maintenance level; Pass hole and the hole on the horizontal stand 5 on the corner bracket 6 through hand tighten screw then, support 2 is fixed on the corner bracket 6.

In use, the first clamp on the desktop 14 is clamped the cross tube 11 of guardrail, corner bracket 6 is fixed between the sheer pole 12 and bed board of guardrail; Adjustment desktop 1 and support 2; Make desktop 1 maintenance level, on corner bracket 6, select suitable hole, the lower end of corner bracket 6 and support 2 is fixed with hand tighten screw and nut; At last, tighten the nut of the upper end of support 2.

As shown in Figure 6, be the embodiment two of fixed support 2 lower ends, the horizontal stand 5 of the lower end of support 2 is long; Horizontal stand 5 is fixed with the second clamp 7 of strip; When desk was installed, the second clamp 7 of strip was clamped guardrail sheer pole 12 and bed board in the lump, makes that support 2 is firm.Second clamp 7 need have certain length with horizontal stand 5, is preferably in more than 20 centimetres.

In use, basic assembling process is identical with embodiment one as shown in Figure 1, and difference is, after with desktop adjustment level, the second clamp 7 that support 2 lower ends connect is clamped sheer pole 12 and bed board, and the nut of tightening support 2 upper ends then gets final product.
