The specific embodiment

As Fig. 1, the embodiment of the present invention the first visual angle stereogram, Fig. 2 is Fig. 1 embodiment the second visual angle stereogram; Fig. 3 is the schematic diagram of Fig. 1 embodiment feet one side; Be explained in conjunction with this three figure:

Table frame comprises base 10 and feet 20; Wherein base 10 comprises stable " work " font plane steelframe that is positioned over level ground, has four terminations, and a beam 11 is installed on each termination;

Feet 20 has two, shape is identical, be separately " X-shaped " of plane, each X-shaped has mainly comprised the first upright hard tube 21 and the second hard tube 22, this first hard tube 21 is relative with both stage casings of the second hard tube 22 bending, and weld together concurrently, weld becomes (shown in Fig. 3) affixed section of A, affixed section of A below two descending forks of pipe are until the stability triangle structure B just putting with the affixed formation one of base 10; The affixed section of A top up fork of two pipes is fixed in horizontal fixed block 30 and forms an inverted stability triangle structure C; This is simple in structure firmly, and easy to process.

Base 10, feet 20 and fixed block 30 form an entirety table frame, have very high mechanical strength and ability of anti-deformation.While being subject to acutely clashing into above table body 40, the framework of whole desk is still stable, can provide effective protection to user.In the present embodiment, fixed block adopts 40mm*20mm, the steel flat tube of wall thickness 1.5mm, and the first hard tube 21 and the second hard tube 22 all adopt external diameter 30mm, the round steel pipe of wall thickness 1.2mm; Bottom adopts 50mm*20mm, the oblate pipe of wall thickness 1.2mm, warp

, just there is slight deformation in test, have good compressive property in the time that desktop 41 is subject to the pressure of 26500N.

Table body 40, is arranged at the top of total, and table body 40 tops comprise a smooth desktop 41; Whole table body 40 is stably fixed on fixed block 30 by lifting unit.Each lifting unit comprises on a body 40 fixing slide block 42 down and is fixed in the slide 31 on fixed block 30.Slide block 42 is slidably matched in the vertical direction and is plugged in slide 31, also has a locking knob 32 in the position of the two coincidence, and this locking knob can be by the relative position locking of slide block 42 and slide 31.All lifting units can be used for regulating the height of desktop 41 with respect to bottom surface, are applicable to the user of height in certain limit.The height that the present embodiment can be realized regulates, and desktop 41 arrives ground scope between 72cm-76cm.On table body 40, the below of desktop 41 has two bend pipes 43, and this bend pipe 43 begins first laterally extending downwards from desktop 41 bottoms, jointly determine the structure of a drawer box-shaped state, and have parallel horizontal stripe 44 between two bend pipes 43; The lateral part of bend pipe 43 can drop to when minimum and abut against on fixed block 30 at table body 40.

On table body 40, in the drawer case between desktop 41 and bend pipe 42, also has a drawer box structure that metallic plate 45 forms.On the one hand, smooth metallic plate can make the more comfort and convenient of use of drawer case, the intensity of firmer on the other hand table body 40, thus improve the energy absorbing while being hit, firmer, shock resistance is better.

This drawer case is except possessing the function of containing objects, in fact also has good anti-seismic performance, because in the time that the impact energy from desktop 41 is too large, under the holding of fixed block 30, can first there is deformation in whole table body 40, thereby the deformation meeting that comprises lifting unit 50, bend pipe 43, desktop 41, horizontal stripe 44 and metallic plate 45 absorbs sizable collision energy, the impact that the feet 20 of below is subject to is eased.As can be seen from Fig., the succinct structure such as the base 10 of the present embodiment and feet 20, table body 40 and beam 11 is easy to split, and it is little after splitting, to take up room, and is beneficial to pile up to transport simultaneously.

Fig. 4 is the interior details schematic diagram of slide and slide block in Fig. 3; Fig. 5 is the detail view of slide shown in Fig. 4 and slide block; The height adjustment mechanism details of this embodiment is described in conjunction with this two figure:

Screw mandrel 50, at vertical direction, is axially fixed at the bottom of slide 31, and also axial and fixed block 30 fixes, and can freely rotate along circumferential; Screw mandrel 50 is engaged in the screw hole 47 on slide block 42 its base plates 46 simultaneously, the lower end of screw mandrel 50 is connected with knob 51, in the time that user rotates with hand operated knob 51, can be under the engagement of screw mandrel 50 drives, slide block 42 is with respect to the upper and lower stepless slip of slide 31, realize the stepless adjustment of desktop in Fig. 1 41 and the relative altitude of fixed block 30, thereby can meet unlimited how possible height requirement in adjustable range.And, from the unidirectional drive principle of screw mandrel 50, screw mandrel 50 can drive slide block 42 to slide up and down, but sliding up and down of slide block 42 cannot make screw mandrel 50 rotate, so tool is of great significance, and this height adjustment can realize and automatically locking, and can not occur because the danger that does not have failure of adjustment that auxiliary positioning is brought even to drop, singlehanded twisting knob 51 just can be realized operation, very convenient; Meanwhile, this structure can be out of shape under certain impact, absorbs sizable impulsive force.In addition, shown in Fig. 4, there is scale in the outside of slide block 42, intuitively indicated the shift length of slide block 42 and slide 31, easily judge the indicating value of current height, and avoid both sides height not wait the desktop inclination causing to there is good degree of regulation and intuitive.

There is sliding tray 48 in the both sides of slide block 42, locking knob 32 its screw rods 36 pass after the screw hole 38 and sliding tray 48 on slide 31, in sliding tray 48, engage with clamp nut 37, meanwhile, the outside that the fastening nut 35 of locking knob 32 is positioned at slide 31 by hand.Visible, manual rotation fastening nut 35, can realize clamp nut 37 pushes mutually with fastening nut 35, the inwall of locking sliding block 42 and slide 31, thereby lock the relative position of slide block 42 with slide 31 completely, can not destroy because the accident of knob 51 touches or damages the fixed relationship of the two, the desk form that regulates height is properly kept, more stable.

Fig. 6 is that Fig. 1 embodiment uses schematic diagram, and in the time there is the junk shown in arrow, weight, personnel can get into a body and hide below 40; Under huge impact, be first that deformation occurs the beam 11 on base 10, sponge portion of energy, then there is deformation at the lower table bulk 40 of holding of fixed block 30, comprise slide block 42, slide 31, bend pipe 43, horizontal stripe 44 and metallic plate 45; Table body 40 occurs in the process of deformation up, can there is hardly deformation in the space of 20 of the feets of below, so, when whole device top deformation has absorbed junk impact, also keep the good protection form in below, there is good shock resistance, greatly safeguarded the safety of hiding personnel.

The present embodiment two has also been used the desktop 41 that environment-friendly materials support in a large number, and paint on each metalwork, makes the whole device can have good environmental protection characteristic, easily recycling.

The above, only for preferred embodiment of the present invention, therefore can not limit according to this scope of the invention process, the equivalence of doing according to the scope of the claims of the present invention and description changes and modifies, and all should still belong in the scope that the present invention contains.
