[0002] A bed frame, as the name implies, is the frame of a bed, usually including one end for supporting the head connected to the bed feet, one end for supporting the feet connected to the bed feet, and the connecting side edges or cross bars. A pneumatic bed has a pneumatic pull rod between the mattress and the bed body, so it is named a pneumatic bed. The bed board and the mattress can be easily lifted. A pneumatic mattress is generally used in combination with a pneumatic frame. The pneumatic frame uses the mortise and tenon structure of wood, and the most prominent contribution of the mortise and tenon structure is its application in architecture.

[0003] The joints of common pneumatic bed frames generally adopt the mortise and tenon structure, and after being connected by the mortise and tenon structure, the stress points are relatively small and are prone to loosening after being subjected to lateral forces for a long time. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a pneumatic frame, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions: including: a horizontal main frame board, two groups of longitudinally arranged frame boards oppositely distributed above the horizontal main frame board, and a central frame board arranged between the two groups of longitudinally arranged frame boards.

[0006] It further includes:

[0007] A positioning slot is opened at the end of the horizontal main frame board, and a positioning card slot is arranged on one side of the positioning slot;

[0008] A positioning convex block is arranged at the end of the longitudinal frame board, and a positioning through slot that can extend into the positioning card slot is arranged on one side of the positioning convex block;

[0009] Reinforcing plates are fixedly arranged on the side walls of the longitudinal frame board and the horizontal main frame board. An upwardly protruding positioning sleeve column is fixedly arranged at the bent part of the reinforcing plate, a support block is arranged above the positioning sleeve column, and a support socket is opened on the surface of the support block.

[0010] Further, a bent part is arranged at the connection between the positioning convex block and the front end of the longitudinal frame board, and the bent part is adapted to the bent part of the positioning slot.

[0011] Further, the height of the positioning slot is the same as the height of the positioning convex block.

[0012] Further, bolt through holes corresponding in position are opened on the surfaces of the horizontal main frame board and the longitudinal frame board, and positioning screw rods are inserted into the slots of the bolt through holes.

[0013] Further, the support sockets are opened at the lower part of the support block and are oppositely distributed on both sides of the support block.

[0014] Furthermore, a central frame groove is provided at the center of the horizontal main frame plate, and plate positioning blocks adapted to the groove shape of the central frame groove are fixedly provided at both ends of the central frame plate.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In this application, the mortise and tenon joint is completed through the combination of the positioning bump, the positioning through groove, the positioning slot and the positioning card slot. At the same time, the combination of the bolt through hole and the positioning screw rod is used to reinforce the horizontal main frame plate and the vertical frame plate. After the mortise and tenon joint between the horizontal main frame plate and the vertical frame plate is completed, and the two groups of positioning sleeve columns are at the same level, the supporting strength of the included angle between the horizontal main frame plate and the vertical frame plate can be enhanced by longitudinally sleeving the supporting block and combining the supporting socket with the positioning sleeve column, thereby improving the lateral supporting force of the entire pneumatic frame and further enhancing the stability of the entire pneumatic frame.

A number of sets of perforations for combining with the cross plate of the bed body are longitudinally opened on the surfaces of the horizontal main frame plate 1 and the central frame plate 13. The entire pneumatic frame is composed of two sets of horizontal main frame plates 1, longitudinal frame plates 2, and a central frame plate 13. Among them, the horizontal main frame plates 1 and the longitudinal frame plates 2 form a rectangular frame, and the central frame plate 13 is horizontally spanned between the two sets of horizontal main frame plates 1 to provide intermediate strength support.

[0024] A positioning slot 3 is opened at the end of the horizontal main frame plate 1. A positioning card slot 4 is provided on one side of the positioning slot 3. The slot depth of the positioning slot 3 is the same as the slot depth of the positioning card slot 4. A positioning convex block 5 is provided at the end of the longitudinal frame plate 2. The height of the positioning convex block 5 is the same as the slot depth of the positioning slot 3. At the same time, a positioning through slot 6 that can extend into the slot of the positioning card slot 4 is provided on one side of the positioning convex block 5. That is, when the horizontal main frame plate 1 and the longitudinal frame plate 2 are combined, the positioning convex block 5 can be combined in the slot of the positioning slot 3, and the positioning through slot 6 is snapped into the slot of the positioning card slot 4, so that a part between the positioning convex block 5 and the positioning through slot 6 is snapped into the cavity between the two sets of positioning slots 3. A bending portion is provided at the connection between the positioning convex block 5 and the front end of the longitudinal frame plate 2, and the bending portion is adapted to the bending portion of the positioning slot 3. When the ends of the horizontal main frame plate 1 and the longitudinal frame plate 2 are combined, the two positioning convex blocks 5 protruding from the front end of the longitudinal frame plate 2 will be placed on the bending portion of the positioning slot 3, and at the same time, the bottom of the slot of the positioning convex block 5 is placed on the bottom of the slot of the positioning card slot 4.
