Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the self-overturning chair comprises a support frame 1, a deck plate 2 and a self-overturning seat plate 3, wherein the support frame 1 comprises a support main beam 112 and a support cross beam 111 connected to the support main beam 112, the deck plate 2 is fixed on the support cross beam 111, and the self-overturning seat is fixed on the support main beam 112.

As shown in fig. 2 and 3, the supporting beam 111 is provided with the slot 4 along the length direction of the supporting beam 111, the opening width of the slot 4 is smaller than the width of the bottom of the slot 4, the cross section of the slot 4 in this embodiment is T-shaped, the deck plate 2 is provided with the insertion block 5 matching with the slot 4 along the width direction of the deck plate 2, the cross section of the insertion block 5 is also T-shaped, so as to facilitate the insertion of the insertion block 5 into the slot 4, the supporting beam 111 is provided with the insertion port 14 communicating with the slot 4, and when in use, the insertion block 5 is inserted into the slot 4 through the insertion port 14.

Wherein, be provided with spacing mouthful 6 towards deck plate 2 side at support girder 112, when the inserted block 5 inserts in the slot 4, one side of deck plate 2 will insert gradually in the spacing mouthful 6, and the inserted block 5 gets into the slot 4 completely when the deck plate 2 inserts inside the spacing mouthful 6 and the mutual joint of the two. Be provided with limiting plate 7 in spacing mouthful 6, limiting plate 7 is perpendicular with the plane at deck plate 2 place, and limiting plate 7 is divided into two with spacing mouthful 6, is provided with spacing groove 8 on deck plate 2, and when deck plate 2 inserted slot 4 gradually, limiting plate 7 will insert spacing inslot 8 gradually, and then made deck plate 2 accomplish the installation.

As shown in fig. 2 and 3, a limiting member is disposed between the supporting beam 111 and the insert block 5, and the insert block 5 can be prevented from sliding out of the slot 4 after the deck plate 2 is fixed by the limiting member, so that the deck plate 2 is more stable in use. The locating part includes locking bolt 9, and locking bolt 9 runs through supporting beam 111 and inserted block 5, because the opening of slot 4 is less, consequently inserted block 5 can only follow inserted hole 14 and slide, and can prevent inserted block 5 to slide in slot 4 through locking bolt 9, and then makes inserted block 5 can not follow inserted hole 14 and go out the roll-off for deck plate 2 is fixed.

As shown in fig. 4 and 5, wherein the insert block 5 is detachably connected to the deck plate 2, a threaded sleeve 10 is embedded in the deck plate 2, a fastening bolt 11 is provided through the insert block 5, the head of the fastening bolt 11 abuts against the insert block 5, the end of the fastening bolt 11 is located in the threaded sleeve 10 and is in threaded connection with the threaded sleeve 10, in use, the insert block 5 is placed on the deck plate 2, the fastening bolt 11 penetrates through the insert block 5 and is inserted into the threaded sleeve 10, and then the fastening bolt 11 is selected to fix the insert block 5 on the deck plate 2.

As shown in fig. 5, the thread bushing 10 includes a fixed section 101 and an expansion section 102, an expansion notch 12 is provided at the expansion section 102, the diameter of an inner hole at the expansion section 102 is gradually reduced from a side close to the fixed section 101 to a side far from the fixed section 101, a plurality of teeth 13 are provided on an outer wall of the expansion section 102, and a thread is provided on an inner wall of the fixed section 101.

In use, the fastening bolt 11 is inserted into the threaded sleeve 10, then the fastening bolt 11 is rotated, the end of the fastening bolt 11 is gradually inserted into the expansion section 102, the expansion section 102 is gradually expanded under the action of the fastening bolt 11 because the inner hole at the expansion section 102 is tapered, and the teeth 13 are inserted into the table top plate 2, so that the connection strength between the threaded sleeve 10 and the table top plate 2 is higher.

Between thread bush 10 and deck plate 2, all be provided with the glue layer between inserted block 5 and the deck plate 2, make the deck plate 2 inseparabler with being connected between inserted block 5 through the glue layer, make difficult separation between deck plate 2 and the inserted block 5 in the later stage use.

Only the locking bolt 9 needs to be screwed when the locking bolt 9 is assembled on an installation site, and the locking bolt 9 only can be subjected to force perpendicular to the axial direction of the locking bolt 9, so that the fixing strength of the table panel 2 is not easily influenced when the locking bolt 9 slides, and meanwhile, the probability of sliding is greatly reduced because fewer bolts need to be screwed. And if the sliding wire appears during production in a production workshop, the connecting piece can be reworked and manufactured, and the reliable connecting strength between the connecting pieces when leaving a factory can be ensured.

When the insert block 5 is fixed on the table top plate 2, glue is firstly coated on the corresponding position of the table top plate 2, glue is simultaneously coated between the thread sleeve 10 and the table top plate 2, then the insert block 5 is attached to the table top plate 2, and then the insert block 5 is fixed on the table top plate 2 through the fastening bolt 11. When the bench is installed on site, the insert 5 is inserted into the slot 4 from the insertion hole 14 until the limiting plate 7 enters the limiting groove 8 and the side wall of the table top plate 2 is abutted against the inner wall of the limiting opening 6, and then the insert 5 and the supporting beam 111 are fixed together through the locking bolt 9, so that the bench is simple and convenient to install.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
