The utility model discloses a cantilever type shell fastening structure which comprises a clamping hook 11 arranged on a frame cover 1 and a fastening seat 21 arranged at an opening of a furnace body 2. The opening is not limited to the top of the shaft 2. In this embodiment, the top of the furnace body 2 is inclined to the outer periphery, and the buckling seat 21 is disposed on the inner sidewall of the furnace body 2 and near the opening at the top of the furnace body 2.

The clamping hook 11 and the frame cover 1 are integrally formed, and the buckling seat 21 and the furnace body 2 are integrally formed. The fastening seat 21 can be made by a die with a structure of oblique top or inner row, etc., thereby shortening the travel of the die and enabling the clamping hook 11 to be fastened with the fastening seat 21 more easily, considering the feasibility of matching with the die.

When the frame cover 1 is installed on the furnace body 2, the clamping hooks 11 are inserted into the buckling seats 21 and are buckled with the buckling seats, so that the frame cover 1 and the furnace body 2 are fixed. The hooks 11 and the buckling seats 21 are in one-to-one correspondence, and the number of the buckling seats 21 can be set according to the size of the actual furnace body 2. In this embodiment, the section of the furnace body 2 is square, and two buckling seats 21 are arranged on each side edge of the furnace body at intervals.

The buckling seat 21 includes a buckling beam 211, an abutting portion 212 and a snap 213. The bottom of the abutting part 212 is connected with the furnace body 2, and the other end is an insertion end which extends upwards to hang in the air, so that a cantilever structure is formed. Both ends of the buckling beam 211 are connected with the abutting portion 212, and are positioned at one side of the abutting portion 212 away from the inner side wall of the furnace shaft 2. An assembly channel communicated with the inner cavity of the furnace body 2 is formed between the abutting part 212 and the buckling beam 211, when the clamping hook 11 is inserted into the assembly channel, the elastic buckle 213 pushes the clamping hook 11 to be buckled with the buckling beam 211, and when the disassembly is realized, a user can realize the separation of the frame cover 11 and the furnace body 2 by only directly pressing the clamping hook 11 in the inner cavity of the furnace body 2.

The snap 213 is provided on the abutment 212. The snap 213 includes an elastic tab 2131 and a tightening tab 2132.

The tightening boss 2132 is disposed on the elastic piece 2131 and protrudes toward the direction of the assembly channel, and the bottom of the hook 11 is provided with an inclined abutment surface 111 that mates with the tightening boss 2132.

Preferably, the width of the elastic piece 2131 gradually widens from the movable end toward the direction of connection with the abutting portion 212, so as to form a V-shaped structure, so that the resilience of the elastic buckle 213 gradually increases, and the elastic force thereof has a gradual effect, so as to ensure that the hook 11 is fastened with the fastening beam 211. The elastic piece 2131 has a thickness of 0.8mm, and a thickness smaller than the abutting portion 212, thereby scientifically controlling the elasticity of the snap 213.

In order to improve the stability of the fastening connection between the fastening seat 21 and the hook 11, preferably, the middle portion of the fastening beam 211 is further connected to the abutment portion 212 through the first supporting rib 214, so as to avoid the fastening beam 211 from being deformed greatly during the fastening process. The first support rib 214 divides the assembly channel into a left channel and a right channel, and the hooks 11 include left hooks 11 and right hooks 11 respectively inserted into the left channel and the right channel, forming a double door structure. The number of the elastic buckles 213 is two, and the elastic buckles are respectively matched with the left clamping hook 11 and the right clamping hook 11.

The shaft 2 is further provided with a second support rib 215 connected to the abutting portion 212, so as to support the abutting portion 212. The second supporting ribs 215 may be connected to the middle of the abutting portion 212, in this embodiment, the second supporting ribs 215 are symmetrically disposed on two sides of the buckling seat 21, so as to form the buckling seat 21 structure in cooperation with a mold.

The hook-shaped structure at the end part of the clamping hook 11 is buckled with the buckling beam 211, the hook-shaped structure is provided with an abutting surface 112 buckled with the buckling beam 211, the abutting surface 112 gradually inclines downwards along the direction from inside to outside, namely, the abutting surface 112 gradually inclines downwards along the direction extending to the buckling beam 211, so that when the elastic buckle 213 presses the clamping hook 11 to the buckling beam 211, the abutting surface 112 can be attached to the buckling beam 211 after the clamping hook 11 is pressed and deformed, the abutting surface 112 is prevented from loosening due to a gap between the abutting surface 112 and the buckling beam 211, and the buckling stability is improved.

The frame cover 1 is provided with a first limit boss 12 corresponding to the abutting portion 212, and the first limit boss 12 is attached to the top of the abutting portion 212. In this embodiment, the first limiting boss 12 is annular.

The top of the furnace body 2 is also provided with an annular positioning groove 22, and the frame cover 1 is also provided with a second limiting boss 13 which is matched with the positioning groove 22. Thereby limiting the stroke of inserting the clamping hook 11 into the buckling seat 21 and the relative positions of the frame cover 1 and the furnace body 2, and ensuring that the elastic buckle 213 is matched with the abutting surface 111 of the clamping hook 11.

The top of the abutting part 212 and the top of the buckling beam 211 are respectively provided with a guide surface 216 which is convenient for the bottom of the clamping hook 11 to be inserted, and the guide surfaces 216 are obliquely arranged to form a conical insertion port. The bottom of the clamping hook 11 is arranged to be conical corresponding to the plug-in interface, so that the guiding function of the guiding surface 216 on the clamping hook 11 is realized in the buckling process, and the installation efficiency is improved.

The shaft 2 is further provided with first guide members 23, and in this embodiment, the first guide members 23 are distributed at four corner positions of the shaft 2, and may be actually laid out according to the structure of the shaft 2. The frame cover 1 is provided with a second guide member 14 matched with the first guide member 23. The matching can realize positioning by means of magnetic attraction and the like. In this embodiment, the first guiding member 23 is in a column shape, the second guiding member 14 is in a tubular shape, and the first guiding member 23 is inserted into the second guiding member 14, and by means of plug-in fit, the guiding and positioning of the frame cover 1 is achieved in the installation process.

When the hook 11 is installed, the hook 11 corresponds to the assembly channel, the hook 11 is pressed into the buckling seat 21 along the assembly channel, one side of the hook-shaped structure of the hook 11 is abutted against the buckling beam 211, and the other side of the hook pushes the elastic buckle 213 to deform and turn outwards. Then, when the hook-shaped structure passes through the buckling beam 211, the abutting force of the buckling beam 211 to the clamping hook 11 disappears, and at the moment, the elastic buckle 213 rebounds to push the clamping hook 11 to the buckling beam 211 so as to enable the clamping hook to be mutually attached and fastened, and meanwhile, the limit boss of the frame cover 1 abuts against the furnace body 2, so that the installation is completed.

When the frame cover 1 is detached, the clamping hooks 11 are only required to be pressed through the inner cavity of the furnace body 2, so that the clamping hooks 11 are separated from the buckling beams 211 by overcoming the elastic force of the elastic buckles 213, and then the clamping hooks 11 can slide out of the assembly channel by lifting the frame cover 1 upwards, so that the frame cover 1 is detached.

The improved buckling structure of the cantilever type shell body buckling structure can more easily realize the tight buckling of the frame cover and the furnace body and prevent the frame cover from tripping. Meanwhile, the structure is convenient for demolding during processing, reduces the complexity of the mold, is suitable for various demolding structures and shortens the mold stroke.
