DETAILED DESCRIPTION

[0028] In order to facilitate understanding of the present application, the present application will be more fully described below with reference to the related drawings. The preferred embodiments of the present application are shown in the drawings.

[0029] As Figures 1 to 3 ​​As shown in the drawings, a kind of oven air nozzle buckle anti-falling structure 10, including buckle assembly 100 and anti-falling component 200, buckle assembly 100 includes buckle block 110, swing block 120 and buckle ring 130, buckle block 110 is used to be set on support seat 20, buckle block 110 is set with clamping groove 111, swing block 120 is used to be rotationally set on oven body 30, buckle ring 130 is rotationally set on swing block 120, swing block 120 is used to drive buckle ring 130 and clamping groove 111 buckle, anti-falling component 200 includes base 210 and lock ring 220, base 210 is used to be set on oven body 30, base 210 is set with sliding hole 211, lock ring 220 is threaded in sliding hole 211, lock ring 220 is used to buckle the end of swing block 120 away from buckle ring 130 under the action of gravity.

[0030] It needs to be explained that buckle assembly 100 is used to buckle oven body 30 and support seat 20, anti-falling component 200 is used to reinforce buckle assembly 100, to avoid buckle assembly 100 from falling accidentally.Specifically, buckle block 110 is welded or installed on support seat 20 using screw.Wherein support seat 20 can be plate structure installed on feeding belt, which is used to support oven body 30.Buckle block 110 is set with clamping groove 111, swing block 120 is rotationally installed on the outer side wall of oven body 30, and buckle ring 130 is rotationally installed on swing block 120.In this way, when swing block 120 is rotated under force, swing block 120 can drive buckle ring 130 to buckle in clamping groove 111, so that oven body 30 is reliably fixed with support seat 20 under the buckling action of buckle assembly 100.Further, base 210 is also installed on the outer side wall of oven body 30, wherein base 210 is above swing block 120 in vertical direction, long strip-shaped sliding hole 211 is set on base 210, lock ring 220 is threaded through sliding hole 211, so that the part of lock ring 220 away from sliding hole 211 will descend along vertical direction under the action of its own gravity, so that lock ring 220 buckles on swing block 120.In this way, since swing block 120 is buckled by upward swinging to make buckle ring 130 buckle clamping groove 111.When oven body 30 shakes, even if swing block 120 is loosened and swings downward, since buckle ring 130 buckles swing block 120, swing block 120 cannot continue to swing downward, so as to achieve anti-loosening, and ensure that oven body 30 is reliably fixed with support seat 20.

[0031] As shown in the drawings, Figure 4 In an embodiment, buckle assembly 100 also includes bottom block 141, bottom block 141 is set on oven body 30, and opposite sides of bottom block 141 are respectively provided with a support ear 142, two support ears 142 are threaded with a rotating shaft 143, rotating shaft 143 is threaded through swing block 120, so that swing block 120 rotates relative to bottom block 141.

[0032] It should be noted that the base block 141 is mounted on the oven body 30, with the support ears 142 located on opposite sides of the base block 141. For example, the support ears 142 and the base block 141 are integrally formed, and the support ears 142 can be bent to form a right angle with the base block 141 through a bending process. Furthermore, the rotating shaft 143 passes through the swing block 120 and the two support ears 142 respectively, thus allowing the swing block 120 to rotate relative to the rotating shaft 143.

[0033] like Figure 4 As shown, in one embodiment, a torsion spring 144 is sleeved on the rotating shaft 143. The torsion spring 144 abuts against the swing block 120 and the bottom block 141 respectively. The torsion spring 144 is used to push the swing block 120 so that the swing block 120 drives the buckle 130 to disengage from the slot 111.

[0034] Thus, the torsion spring 144 pushes the swing block 120, causing the swing block 120 to tend to rotate downwards in its natural state, thereby causing the retaining ring 130 to tend to disengage from the retaining groove 111. Thus, when the swing block 120 is subjected to an external force that overcomes the elastic force of the torsion spring 144 and rotates upwards, it can drive the retaining ring 130 to lock into the retaining groove 111. At this time, the swing block 120 is attached to the outer wall of the oven body 30, and the swing block 120 can be stably held in this position.

[0035] In one embodiment, the base 210 is welded to the outer wall of the oven body 30. This ensures that the base 210 is stably fixed to the oven body 30.

[0036] like Figure 4 As shown, in one embodiment, the distance between the sliding hole 211 and the outer wall of the base 210 gradually decreases in the vertically upward direction.

[0037] Thus, the sliding hole 211 is inclined relative to the base 210 in the vertical direction. Therefore, when the locking ring 220 engages with the swing block 120 under its own weight, if the locking ring 220 is vibrated and rises along the sliding hole 211, the inclined structure of the sliding hole 211 means that the center of gravity of the locking ring 220 will shift outwards during its ascent. As the center of gravity of the locking ring 220 shifts outwards, the part of the locking ring 220 away from the sliding hole 211 will reliably descend, thereby securing the swing block 120 and effectively preventing the locking ring 220 from separating from the swing block 120 due to vibration. Therefore, it effectively ensures the anti-detachment function of the swing block 120.

[0038] like Figure 3 and Figure 4 As shown, in one embodiment, the base 210 includes a seat body 212 and a limiting block 213. The seat body 212 is disposed on the oven body 30, and a sliding groove is provided in the seat body 212. The limiting block 213 is disposed on the top of the seat body 212 so that the sliding groove and the limiting block 213 together form a sliding hole 211.

[0039] It should be noted that the base 210 is formed by combining the seat 212 and the limiting block 213. Thus, when the size of the locking ring 220 is not suitable, the locking ring 220 can be replaced by removing the limiting block 213.

[0040] like Figure 1 As shown, in one embodiment, the base 212 is provided with a first locking hole 2121, and the limiting block 213 is provided with a second locking hole 2131, and the second locking hole 2131 is aligned with the first locking hole 2121.

[0041] Thus, by using screws or other fasteners to sequentially screw into the second locking hole 2131 and the first locking hole 2121, the limiting block 213 can be reliably fixed on the base 212.

[0042] like Figure 5 As shown, in one embodiment, the outer wall of the locking ring 220 is covered with a wear-resistant layer 230.

[0043] It should be noted that the locking ring 220 can be made of stainless steel. Since the locking ring 220 engages with the swing block 120 by its own weight, it will continuously rub against the swing block 120 and the sliding hole 211 under vibration. Over time, this can easily generate fine debris. In a high-dust-proof workshop, such debris poses a safety hazard, potentially leading to explosions. Therefore, to avoid this safety hazard, a wear-resistant layer 230 is applied to the outer wall of the locking ring 220. The wear-resistant layer 230 contacts the inner wall of the swing block 120 and the sliding hole 211, preventing debris generation. In one embodiment, the wear-resistant layer 230 is a Teflon layer formed by electroplating, which effectively prevents debris generation due to friction.

[0044] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood to include, but is not limited to, locking and fixing with screws / bolts, and welding. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
