The door 4 is thus rotated around the door bolt 22 along the left door frame 21, and the door 4 is locked in the right door frame 31.
With reference to figures 3-5 of the drawings,
the furnace door 4 is fixed with a baffle strip 52, the baffle strip 52 is welded on the inner side of the furnace door 4, the baffle strip 52 is positioned in the concave groove 51, and one end of the unlocking plate 6 is abutted against the baffle strip 52 so as to realize the uniform arrangement of the surface of the unlocking plate 6 and the surface of the furnace door 4; the other end of the unlocking plate 6 and the inside of the concave groove 51 have a space for giving way, and the other end of the unlocking plate 6 is used for being pressed and rotated by a user.
The furnace door 4 is rotationally connected with a rotating shaft 71 for fixing the unlocking plate 6, the rotating shaft 71 is rotationally connected in the furnace door 4, the rotating shaft 71 is fixedly connected with a linkage rod 72 which is vertically and parallelly arranged, and a transverse metal strip is welded between the rotating shaft 71 and the linkage rod 72; the rotating shaft 71 and the linkage rod 72 are vertically arranged and parallel.
The two ends of the linkage rod 72 are adjacent to the upper end and the lower end of the oven door 4, two lock hooks 76 are sleeved on the linkage rod 72, the two lock hooks 76 are positioned at the two ends of the upper end of the linkage rod 72, and the lock hooks 76 can rotate around the linkage rod 72 in the horizontal direction. An upper snap ring and a lower snap ring are fixed on the link 72, and are fixed on the upper side and the lower side of the lock hook 76, and the upper snap ring and the lower snap ring make it difficult for the lock hook 76 to move up and down along the length direction of the link 72.
The latch hook 76 has an overall L-like structure, the latch hook 76 includes a hook portion 761, the hook portion 761 has an arc-shaped side surface bent toward the inside of the body of the latch hook 76, and the hook portion 761 and the link lever 72 are located on both sides of the intermediate shaft 73;
the latch hook 76 is rotatably connected with the intermediate shaft 73, the furnace door 4 is provided with a sliding hole 74 for sliding the intermediate shaft 73, the inner side of the furnace door 4 is fixedly provided with a metal strip, the sliding hole 74 is formed in the metal strip, the sliding hole 74 is a long-strip-shaped hole, the intermediate shaft 73 transversely moves back and forth in the sliding hole 74, the maximum width of the two ends of the intermediate shaft 73 is larger than the width of the sliding hole, therefore, the intermediate shaft 73 can stably move in the sliding hole 74, and the intermediate shaft 73 can rotate in the sliding hole 74.
The furnace door 4 is provided with an elastic piece 75 for pulling the lock hook 76 to be kept at the locking station, the elastic piece 75 is a tension spring, one end of the tension spring is fixed on the furnace door 4, and the other end of the tension spring is fixed on the lock hook 76 so as to pull the hook 761 to be arranged in a direction facing the inner side of the furnace door 4;
the latch hook 76 is always held in the latch position by the tension spring.
The right door frame 31 is mounted with a latch 32 into which the hook 761 slides when the door 4 is closed; the lock catch 32 is a concave open-loop structure;
when the furnace door 4 is screwed into the furnace body 1, the arc-shaped side surface of the hook 761 abuts against the lock catch 32 to overcome the tension force of the tension spring, the hook 761 rotates away from the lock catch 32 along with further folding of the furnace door 4, the lock hook 76 moves away from the lock catch 32 along the sliding hole 74, the back surface of the hook 761 is separated from the lock hook 76 when the furnace door 4 is known to be closed, and the inner side of the hook 761 is buckled with the lock catch 32 under the driving of the tension spring, so that the action that the hook 761 slides into the lock catch 32 is realized.
The both ends of hasp 32 are fixed with fixed plate 33, and fixed plate 33 installs right door frame 31, has seted up waist round hole 34 on the fixed plate 33, and waist round hole 34 installs the adjusting screw 35 of connection right door frame 31.
The unlocking principle refers to fig. 6, in which the latch hook 76 is locked to the lock catch 32, and when unlocking is needed, referring to fig. 7, the unlocking plate 6 is used for pressing the unlocking plate 6, the unlocking plate 6 rotates anticlockwise, the rotating shaft 71 and the linkage rod 72 are driven to rotate anticlockwise, and the counter-clockwise rotation of the connecting rod drives the latch hook 76 to rotate clockwise around the intermediate shaft 73 integrally due to the fact that the latch hook 76 is pulled by the tension spring, and the hook 761 of the latch hook 76 and the lock catch 32 complete the separation action.
The advantage in this design lies in, with the release board 6 structure of furnace gate 4 surface level arrangement, avoid the user to collide with to and the simple structure's two latch hook 76 designs, under the state of locking, furnace gate 4 locking is stable.
Embodiment 2 is a door structure for fireplace, which is different from embodiment 1 in that, referring to fig. 8-9, a locking screw 81 is installed on a side of the furnace body 1, a cap portion of the locking screw 81 is located outside the furnace body 1, and a slot is formed in the cap portion to facilitate unscrewing of a screwdriver.
The threaded end of the locking screw 81 abuts against the side of the keeper 22. A rubber pad 82 is fixed to the threaded end of the locking screw 81, and the rubber pad 82 abuts against the side surface of the door bolt 22.
Obviously, when there is child in user's home, can lock screw 81 and screw, because keeper 22 and furnace gate 4 are fixed together, keeper 22 can't rotate, and furnace gate 4 can't open, even after child opened the lock of furnace gate 4 like this, furnace gate 4 also can't effectually open, avoids child and the chance of furnace gate 4 flame contact for the use of fireplace is safer.
