Detailed Description

In order to make the technical solutions of the present invention better understood, those skilled in the art will now describe the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 3, a wood pattern structure for manufacturing a sand mold comprises a plurality of wood pattern frames 1 which are mutually assembled and have a rectangular structure, and a quick overlocking device 2 for locking/releasing the assembling joint of the wood pattern frames 1. In short, as can be seen from fig. 1, the wood pattern frame 1 comprises symmetrically distributed side plates I11 and symmetrically distributed side plates II12, and the two side plates II12 are located between the two side plates I11 and clamped and fixed by the two side plates I11. And the side walls of the side plate I11 and the side plate II12 are centrally provided with a tooth mouth plate 3 fixed by screws. Therefore, when the side plate I11 and the side plate II12 are assembled to form the wood pattern frame 1, the notched plates 3 on the side plate I11 and the side plate II12 are spliced together to form a serging rail matched with the quick serger 2 (the state shown in figure 2).

In the specific implementation process, the quick overlock machine 2 includes a looping box 21, a ratchet 22 and pawls 23 symmetrically distributed about the center of the ratchet 22, the ratchet 22 is axially and rotatably disposed inside the looping box 21, the two pawls 23 are also axially and rotatably disposed inside the looping box 21, and the inner walls of two opposite sides of the looping box 21 are respectively provided with a blocking spring 7 (shown in fig. 3) for driving the pawls 23 to approach the ratchet 22 to lock the rotation of the ratchet 22.

In a further embodiment, as can be seen from fig. 2 and 3, a side wall of one side of the linking box 21 is provided with a guide slot 5, inner walls of the guide slot 5 adjacent to two opposite sides of the port are respectively provided with a guide bar 6, and a side wall of the serging rail insert is provided with a guide rail slot 31. And the overlock rail is inserted into the guide groove 5 and the guide bar 6 is positioned in the guide groove 31.

The matching relationship of the dial 81 and the two pawls 23 is as follows:

when the shift lever 8 is positioned at the center line of the looping box 21, the shift block 81 is positioned between the two pawls 23, and the pawls 23 lose the interference of the shift block 81 at the moment, and approach the ratchet wheel 22 under the action of the resistance spring 7, so that the ratchet wheel 22 is meshed with the pawls 23, and the ratchet wheel 22 is locked and cannot move;

when the shift lever 8 is on the left side, the shift block 81 rotates synchronously and abuts against the pawl 23 on the left side, the pawl 23 on the left side abuts against the shift block 81 at the moment, so that the pawl 23 is separated from the ratchet wheel 22, and the ratchet wheel 22 can keep rotating clockwise at the moment;

when the shift lever 8 is on the right side, the shift block 81 rotates synchronously and abuts against the right-side pawl 23, and the right-side pawl 23 abuts against the shift block 81 at this time, so that the pawl 23 is disengaged from the ratchet wheel 22, and the ratchet wheel 22 can keep rotating counterclockwise at this time.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the utility model.
