In view of the deficiencies of the prior art, one of goal of the invention of the invention is intended to further change the structure work of lower body frame Into while so that it is kept receiving function, remaining able to provide for the object to be supported rested on and effectively support and have The ideal ability for resisting resistance to deformation laterally or longitudinally.In consideration of it, the present invention proposes a kind of lower master for laboratory sales counter Frame includes to connect in length and breadth and is in the lower longitudinal beam of proximate matter shape and lower transverse beam respectively, which is characterized in that the lower body frame is whole It is in the shape of a frame on body, the lower transverse beam, which includes at least, to be had on the outside of the front positioned at the lower body frame, back outer fix it is front lower Transverse beam and afterwards lower transverse beam；The lower longitudinal beam, which includes at least, the leftmost outer positioned at the lower body frame, rightmost outer position The lower-left longitudinal beam set and bottom right longitudinal beam and setting are between the lower-left longitudinal beam and bottom right longitudinal beam and laterally separated Longitudinal beam under two centres of arrangement, under two centres longitudinal beam be connected to the front lower transverse beam and it is described after under Between transverse beam, the position under two centres between longitudinal beam does not arrange the front lower transverse beam and becomes lateral vacancy Position.

Wherein, the lower body frame belongs to a kind of supporting frame, can apply and be used as support substrate with the lower part of sales counter.

Wherein, the lower body frame is in the shape of a frame on the whole, so by the lower longitudinal beam and lower transverse beam jointly in institute It states and defines space in frame on lower body frame.

Wherein, the lower longitudinal beam is including at least the leftmost outer having positioned at the lower body frame, a left side for rightmost outer position Lower longitudinal beam and bottom right longitudinal beam, the lower transverse beam, which includes at least, to be had on the outside of the front of the lower body frame, on the outside of back The front lower transverse beam of position and afterwards lower transverse beam.Features described above can be read as, the lower-left longitudinal beam, bottom right longitudinal beam, preceding The outside that lower transverse beam and rear lower transverse beam are located at the lower body frame becomes the outer rim of the lower body frame.

Wherein, it is arranged between the lower-left longitudinal beam and bottom right longitudinal beam and is indulged under two centres of laterally separated arrangement Xiang Liang, under two centres longitudinal beam be connected to the front lower transverse beam and it is described after between lower transverse beam.Above-mentioned spy Sign first defines the placement position of longitudinal beam under two centres, and longitudinal beam is located at by described lower vertical under two centres In the frame that Xiang Liang and lower transverse beam are defined in space, and between longitudinal beam has in a lateral direction under two centres Away from.In addition, features described above also define under two centres longitudinal beam respectively with the front lower transverse beam and it is described after lower cross There is connection relation to beam, longitudinal beam and the front lower transverse beam under such two centres, it is described after lower transverse beam in length and breadth It is formed by connecting as the stabilizing mechanism of external vertical or horizontal thrust can be overcome.

Wherein, position does not arrange the front lower transverse beam and becomes lateral vacancy between longitudinal beam under two centres Position.In this way, longitudinal beam surrounds the corresponding transverse direction with positioned at the rear lower transverse beam between them under two centres The concavity vacancy area of vacant locations arrangement.Concavity vacancy area is located in the frame of the lower body frame in space.External object is worn Crossing after the lateral vacant locations can be along for accommodation into concavity vacancy area.

According to above-mentioned technical proposal, compared with prior art, the beneficial technical effect of the present invention lies in：

1. since longitudinal beam is connected between the front lower transverse beam and the rear lower transverse beam under two centres, such as Longitudinal beam is connect in length and breadth with the front lower transverse beam, the rear lower transverse beam in the lower body frame under this two described centres Two left and right small frameworks split of upper formation, the small framework, which itself is to be formed, overcomes external vertical or horizontal thrust Stabilizing mechanism, and then the deformability of the vertical or horizontal thrust of resistance of the lower body frame is enabled to improve at least one times, Compensate for the harmful effect of the settings of the lateral vacant locations to the non-deformability of the lower body frame.In addition, the centre Lower longitudinal beam can also be formed in the medium position of the lower body frame and be supported, and expand the support density of the lower body frame, so as to It is enough to provide support to the bottom core plate for being shelved on the lower body frame and being arranged in the object such as laboratory sales counter of medium position.

2. due under two centres longitudinal beam with after described between them lower transverse beam surround it is corresponding described in The concavity vacancy area of lateral vacant locations arrangement.In this way, external object can house after capable of passing through the lateral vacant locations Into concavity vacancy area.Concavity vacancy area becomes a part for storage space.The lower body frame has the function of receiving.

The beam frame of general frame body is all having the shape of a real square squared profile, very stiff stiff, in order to break through this traditional style, The present invention is improved further the lower body frame, and the lower-left longitudinal beam, bottom right longitudinal beam and the front lower transverse beam are Ladder beam；In terms of cross section, the ladder beam includes upper and lower splits and the upper horizontal pane wall being laterally extended and lower horizontal pane Wall, and between the upper horizontal pane wall and lower horizontal pane wall and the left support frame wall that splits of left and right and right support frame wall, The upper horizontal pane wall and lower horizontal pane wall are substantially parallel to each other arrangement and the horizontal width of the upper horizontal pane wall is more than institute State the horizontal width of lower horizontal pane wall.

Wherein, in terms of cross section, the ladder beam includes upper and lower splits and the upper horizontal pane wall being laterally extended and lower water Flat frame wall, and between the upper horizontal pane wall and lower horizontal pane wall and control the left support frame wall split and right support frame Wall.Features described above defines the cross-sectional structure of the ladder beam, and the ladder beam has the cross-sectional structure of class frame-shaped.It is described Cross section is the section obtained by ladder beam described in the length extending direction cutting of the vertical ladder beam.It should be noted that institute It is the definition given according to the relative bearing between them to state horizontal pane wall and lower horizontal pane wall, and the upper horizontal pane wall is under Horizontal pane wall is the horizontal pane wall split above and below, when one of horizontal pane wall is defined as upper horizontal pane wall, another level Frame wall is lower horizontal pane wall.It is also similarly according to the relative bearing between them the left support frame wall and right support frame wall The definition given, the left support frame wall and right support frame wall are the left and right support frame walls split, when one of support frame When wall is defined as left support frame wall, another support frame wall is right support frame wall.

Wherein, the upper horizontal pane wall and lower horizontal pane wall are substantially parallel to each other arrangement.In this way, working as the lower horizontal pane wall When setting aside on positioning matrix, the positioning reference data provided by the positioning matrix and institute that the lower horizontal pane wall is obtained The positioning reference data for stating the acquisition of horizontal pane wall is almost the same.As long as such positioning matrix can be the lower horizontal pane Wall provides horizontal reference location benchmark, and the upper horizontal pane wall also can be horizontally disposed.In addition, the upper horizontal pane wall Horizontal width is more than the horizontal width of the lower horizontal pane wall.In this way, the upper horizontal pane wall can be the object being supported on Product provide the support of opposite large area, improve stability of strutting system.To sum up, the lower-left longitudinal beam, bottom right longitudinal beam and it is described before Lower transverse beam is ladder beam, the ladder beam have it is upper greatly under thin external appearance characteristic so that the lower body frame keeps good branch Integrally seem very delicate, agile while supportting intensity.

Lower transverse beam can be equally ladder beam after described, but consider in general application scenario, lower cross after described It is not readily observed to beam in hidden state, so it is more front lower than described to descend transverse beam that cross-sectional shape may be used after described The simple proximate matter manufacture of transverse beam.Further technical solution can be the rear lower transverse beam and the front lower transverse direction thus The cross-sectional shape of beam is different.In this way, cross-sectional shape may be used different from the front lower transverse beam in lower transverse beam after described Proximate matter manufacture such as standard specification square steel, channel steel, in this way can be in the case where ensureing the structural strength of the lower body frame Greatly reduce the manufacturing cost of the lower body frame.

In view of in general application scenario, longitudinal beam is in exposed state under the centre, in order to further Optimize the appearance of the upper body frame, further technical solution is also possible that longitudinal beam and the lower-left under two centres The cross-sectional shape of longitudinal beam or bottom right longitudinal beam is identical.Longitudinal beam is also ladder beam under the i.e. described centre.

It can be connected by welding procedure between the lower transverse beam and the lower longitudinal beam, but this mode is not Easy to disassemble, Given this present invention proposes following connection type：

First, for the connection between the front lower transverse beam and the lower-left longitudinal beam, bottom right longitudinal beam, further technology Scheme can be that corner-connecting position passes through second between the front lower transverse beam and the lower-left longitudinal beam, bottom right longitudinal beam Plastic corner transit joint links up.Wherein, the corner-connecting position refer to be respectively formed in the front lower transverse beam with L-type corner between the lower-left longitudinal beam, bottom right longitudinal beam.The corner transit joint is that substantially L-shaped connector has There are longitudinally connected arm and lateral connection arm, the longitudinally connected arm to connect the lower-left longitudinal beam or the bottom right longitudinal beam, and Lateral connection arm connects the front lower transverse beam.In case of no particular description, the corner being discussed below Junction and the corner transit joint have above-mentioned identical meaning, repeat no more.In this way, the front lower transverse beam and institute State lower-left longitudinal beam, bottom right longitudinal beam can split transport, then connect by the second plastic corner transition in erecting bed Head links up, without being attached using the complicated connection type such as welding, even layman also can be non- Often easily complete assembling.

In order to the vacancy area after the rear side of the lower body frame is formed, further technical solution is also possible that described It descends transverse beam between the lower-left longitudinal beam, bottom right longitudinal beam afterwards and they is arranged in エ fonts.In this way, the lower-left Longitudinal beam, bottom right longitudinal beam rear end cross it is described after lower transverse beam extend back.Lower transverse beam and the lower-left are vertical after described Xiang Liang, bottom right longitudinal beam rear elongated end surround it is described after vacancy area.In this way, the lower longitudinal beam can be supported and be extended back Support side plate and so that the top in vacancy area in the rear is formed and be capable of the rear material-putting space of glove, in the rear in material-putting space It can be placed as the service line that experiment provides power source.

In the case of descending transverse beam to be arranged in L fonts with the lower-left longitudinal beam, bottom right longitudinal beam in the rear, after described Connection between lower transverse beam and the lower-left longitudinal beam, bottom right longitudinal beam can also be connected by corner transit joint. But it when lower transverse beam is arranged with the lower-left longitudinal beam, bottom right longitudinal beam in エ fonts after described, is no longer applicable in and passes through corner Transit joint is attached, in consideration of it, present invention further propose that the following technical solution：In the lower-left longitudinal beam, bottom right The third being connected separately on longitudinal beam corresponding to the left and right ends of the rear lower transverse beam connects chock plug, lower transverse beam after described On be provided with the third accommodating chamber that can accommodate third connection chock plug, the both ends of lower transverse beam pass through the third after described Accommodating chamber is socketed on the third connection chock plug of left and right arrangement and is fastenedly connected between them respectively.Wherein, institute The both ends of lower transverse beam can connect chock plug fastening by modes such as bonding, screw connections with the third of corresponding arrangement after stating It connects.In this way, the both ends of the rear lower transverse beam are firmly positioned into the lower-left by third connection chock plug and indulge On Xiang Liang, bottom right longitudinal beam, installation is very convenient.And after completion of installation, third connection chock plug is stowed to described the It will not be substantially exposed outside in three accommodating chambers to influence the appearance of the lower body frame.

It may be used between the third connection chock plug and the lower-left longitudinal beam or bottom right longitudinal beam and for example bond, weld Etc. a variety of connection types.And relatively convenient and with suitable fastness be to use screw connection, therefore further skill Art scheme can be that the third connection chock plug passes through on screw connection to the lower-left longitudinal beam or bottom right longitudinal beam.

It is similar above-mentioned as may be used between longitudinal beam under the centre and the front lower transverse beam or rear lower transverse beam Connection type of the connection chock plug as connector, therefore further technical solution is also possible that in the front lower transverse beam Or the 4th connection chock plug corresponding to the front end or rear end of longitudinal beam under the centre, the centre are connected in rear lower transverse beam The 4th accommodating chamber of the 4th connection chock plug can be accommodated by being provided on lower longitudinal beam, under the centre front end of longitudinal beam or Rear end is socketed on the 4th connection chock plug by the 4th accommodating chamber and is fastenedly connected between them, described the Four connection chock plugs are by screw connection to the front lower transverse beam or afterwards in lower transverse beam.So chock plug is connected by the described 4th The connection type that is attached with it is discussed above arrive it is described after lower transverse beam and the lower-left longitudinal beam, bottom right longitudinal beam it Between it is similar using the technique effect acquired by the connection type that is attached of third connection chock plug, details are not described herein.

In addition to this, when being formed with corner-connecting position between longitudinal beam under the centre and the front lower transverse beam, It can also further adopt the following technical scheme that, the corner-connecting under the centre between longitudinal beam and the front lower transverse beam Position is linked up by third plastic corner transit joint.
