Detailed Description

The following describes a locking type door structure of a long rod hot shears according to the present invention in further detail with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more fully apparent from the following description and appended claims. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.

Example one

The utility model provides a locking type furnace door structure of a long rod hot shearing furnace, as shown in figures 1 and 2, comprising a furnace door 1, wherein a sealing component 2 is arranged in the shell of the furnace door 1, a handle 11 is also arranged on the furnace door 1, and a connecting rod 3 is fixedly connected on the furnace door 1; the supporting seat 4 is arranged on one side of a furnace opening of the furnace body 6, and one end of the connecting rod 3 is rotatably connected with the supporting seat 4;

the locking type furnace door structure of the long-rod hot-shearing furnace further comprises a locking mechanism 5 arranged on the other side of the furnace opening, please refer to fig. 3 and 4, wherein the locking mechanism 5 comprises a buckle base 50 arranged on a furnace body 6 of the aging furnace, both ends of the buckle base 50 are provided with vertical arms 51, the vertical arms 51 are respectively hinged with a locking buckle 52 and a first connecting block 53, one end of the locking buckle 52 close to the first connecting block 53 is connected with a second connecting block 54, preferably, the second connecting block 54 is hinged with the locking buckle 52, a strong spring 55 is connected between the first connecting block 53 and the second connecting block 54, the length of the strong spring 55 is not more than the original length of the furnace door 1 in the opening and closing states, and the first connecting block 53 and the second connecting block 54 are respectively provided with a guide rod 530 and a guide sleeve 540; the guide rod 530 and the guide sleeve 540 are both sleeved in the strong spring 55 to guide the strong spring 55.

With reference to fig. 1 and fig. 2, a clamping groove 520 is formed at one end of the locking buckle 52 close to the oven door 1, a clamping block 10 is disposed on the oven door 1, and the clamping groove 520 is matched with the clamping block 10.

When the oven door 1 is opened, please refer to fig. 3, the oven door 1 is driven by an external force to drive the locking buckle 52 to rotate counterclockwise, the distance between the first connecting block 53 and the second connecting block 54 is shortened, the strong spring 55 contracts, when the strong spring 55 contracts to the shortest, the second connecting block 54 and the locking buckle 52 are blocked by the vertical arm 51, so that the compressed strong spring 55 cannot recover, meanwhile, the elastic force of the strong spring 55 acts on the locking buckle 52 in a reverse manner, the locking buckle 52 is ensured to be outward in direction, and the locking buckle 52 is prevented from reversing when the oven door 1 is closed next time.

When the oven door 1 is closed, referring to fig. 4, the oven door 1 is subjected to an external force to drive the locking buckle 52 to rotate clockwise, the distance between the first connecting block 53 and the second connecting block 54 is increased, the strong spring 55 extends, when the locking buckle 52 rotates to an extreme position, the length of the strong spring 55 is longest, and the strong spring 55 applies pressure to the locking buckle 52 through the first connecting block 53, so that the oven door 1 is closed and always kept in a closed state, and locking is completed.

When the oven door 1 is in an open or closed state, the length of the strong spring 55 is not more than the original length all the time. In the process of opening and closing the furnace door 1, an operator does not need to touch the handle 11 for a long time, so that the hidden danger of scalding caused by the long-time contact between the operator and the furnace door can be effectively avoided; in addition, when the furnace door 1 is closed, if the air pressure in the furnace is too high, the furnace door 1 can automatically pop open to release the pressure under the action of the air pressure, so that the problem that an operator is suddenly knocked open by the furnace door when the operator opens the furnace door 1 due to the action of the air pressure in the traditional thread locking type furnace door is avoided, and potential safety hazards are reduced.

The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and any modification and modification made by those skilled in the art according to the above disclosure are all within the scope of the claims.
