The purpose of this utility model is that present classroom of solution or Conference Room tables and chairs structure in case of emergency are not easy to evacuate rapidly the desk panel seat chair that damages this shortcoming and design a kind of activity of the personnel's of making rapid evacuation.

The utility model desk panel seat chair comprises the chair frame of being made up of bogie side frame and crossbeam, some seat supports, some seats are by reaching seat cushion, some support positioning seats, some table supports, some tables and table connecting base, it is characterized in that also comprising two lugs of wearing pivot hole under the table connecting base, pivot, the vertical component effect and the horizontal part that slightly are L type support positioning seat are installed with the some locating pieces that are used for limiting table support translation-angle respectively, the vertical component effect of support positioning seat, the predetermined position of the lower end of each table support that articulates with vertical component effect and the articulated section of upper end, bogie side frame in the chair frame is fixed with ground and is connected with crossbeam, crossbeam and each seat support are connected and fixed, each seat support is used for locking and connecting seat again and leans on and seat cushion, and crossbeam is connected and fixed each support positioning seat in suitable distance respectively, the predetermined position of the lower end of each table support articulates with the vertical component effect that slightly is L type support positioning seat, its articulated section, upper end borrows following two lugs of pivot and table connecting base to articulate, and table is connected with the table connecting base.

The basic principle that reaches the utility model purpose of design is, borrowing pivot articulating this function by two lugs that it has pivot hole down with the table support with the table connecting base that table fuses, and can make with the pivot is that at least 90 degree are upwards raised at the center.Table support lower end and support positioning seat vertical component effect adopt the pivot joint mode to form the pivot joint state in addition, and the table support is turned to lift backward, add that locating piece on the support positioning seat props up table to put up normal condition or the back that pivots is angled.Moreover the table support, table connecting base, seat support, bogie side frame etc. are that aluminium alloy compacting forms and bogie side frame is fixed in ground, its firm thinking and it.And how many this desk panel seat chairs also can set its length and quantity according to place size, personnel.

Below in conjunction with accompanying drawing the utility model embodiment is described in detail:

Fig. 1 is the structural representation of the desk panel seat chair of the utility model activity.

Structural representation when Fig. 2 upwards starts for the desk panel seat chair table of the utility model activity.

Structural representation when Fig. 3 pivots together with table backward for the desk panel seat chair table support of the utility model activity.

As shown in Figure 1-Figure 3, desk panel seat chair comprises the chair frame of being made up of bogie side frame 11 and crossbeam 12 1, some seat supports 6, some seats is by 71 and seat cushion 72, some support positioning seats 5, some table supports 3, some tables 2 and table connecting base 4, two lugs 41 that band pivot hole 411 is arranged below the table connecting base 4, pivot 40, the vertical component effect 51 that slightly is L type support positioning seat 5 is installed with the some locating

pieces

511 and 521 that are used for limiting table support 3 translation-angles respectively with horizontal part 52, the vertical component effect 51 of support positioning seat 5, the predetermined position 32 of the lower end of each table support 3 that articulates with vertical component effect 51 and the articulated section 31 of upper end, bogie side frame 11 in the chair frame 1 (another bogie side frame is not shown among Fig. 1) is fixed with ground and is connected with crossbeam 12, crossbeam 12 is connected and fixed with each seat support 6, each seat support 6 be used for again locking and connecting the seat by 71 with seat cushion 72, be connected and fixed each support positioning seat 5 in suitable distance on the crossbeam 12, the predetermined position 32 of the lower end of each table support 3 articulates with the vertical component effect that slightly is L type support positioning seat 5 51, two lugs 41 that its articulated section, upper end 31 borrows pivot 40 to have pivot hole 411 below table connecting base 4 articulate, 2 times lockings of each table have table connecting base 4, and just making table 2 can be that at least nine ten degree are upwards raised at the center with the pivot 40 of table support 3 upper ends together with table Connection Block 4.The predetermined position 32 of table support 3 lower ends and the pivot joint of the vertical component effect 51 of support positioning seat 5, when rotating, be subjected to locating piece 511 that support positioning seat 5 vertical component effects 51 and horizontal part 52 set firmly and 521 restriction, can make 3 one-tenths normal conditions of table support or state at angle behind the pivot upwards.
