Description

Technical Field

[0001] The utility model relates to the technical field of air spring manufacturing, in particular to a buckling flap and an air spring buckling tool. Background Art

[0002] The air spring buckling flap engagement tooling includes a plurality of buckling flaps equally divided by the circumference, and the buckling flaps include a slot arranged on one side and a block arranged on the other side. When working, the plurality of buckling flaps gather toward the center of the circle under the action of the power mechanism, and the slots and blocks of adjacent buckling flaps are interlocked to absorb the axial reference error of the engagement tooling caused by equipment processing and assembly.

[0003] However, when the pressing petals are gathered together and the air spring is pressed, the groove and the block extend to the inner side of the engaging tooling, which will cause pressing marks in the shape of grooves and blocks to be left on the pressed surface of the air spring buckle. In addition, since there are radial errors in the assembly of multiple pressing petals, the pressing depths of each pressing petal are different during the pressing process, which affects the pressing effect and the appearance of the air spring.

[0026] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.

[0027] The embodiments of the present utility model are further described below in conjunction with the accompanying drawings.

[0028] See also Figure 1-4 A retaining flap shown includes a retaining flap body 1, a slot 2, a reserved portion 3 and a retaining block 4, wherein the retaining flap body 1 has an outer edge surface 11 and an inner edge surface 12 for contacting the retained object; wherein the slot 2 is arranged on one side of the retaining flap body 1; the slot 2 extends from the outer edge surface 11 toward the inner edge surface 12; wherein the reserved portion 3 is arranged between the slot 2 and the inner edge surface 12 to keep the inner edge surface 12 intact; wherein the retaining block 4 is arranged on the other side of the retaining flap body 1; and the shape of the retaining block 4 matches the slot 2.

[0029] In actual use, the utility model includes a clamping flap body 1, a slot 2 and a block 4, and also includes a reserved portion 3. When the block 4 and the slot 2 of two adjacent clamping flap bodies 1 cooperate with each other, the reference error of the axial direction of the engaging tooling caused by equipment processing and assembly can be absorbed, and due to the existence of the reserved portion 3, the block 4 and the slot 2 cannot extend to the inner edge surface 12, so that the inner edge surface 12 remains intact, avoiding the appearance of clamping marks in the shape of the slot and the block when contacting the clamped object, and the clamping depth consistency is good, thereby improving the clamping effect and aesthetics.

[0030] It can be understood that the retaining flap body 1 of the utility model can be used in combination according to the shape of the product to be retained. For example, when the surface of the product to be retained is an arc, multiple retaining flap bodies 1 can be arranged in an arc shape, and the inner edge surface 12 is designed to be an arc that matches the surface of the product to be retained so as to retain it; when the surface of the product to be retained is a rectangle, multiple retaining flap bodies 1 can be arranged in a rectangular shape, and the inner edge surface 12 is designed to be a plane that matches the surface of the product to be retained so as to retain it.

[0031] Please continue reading Figure 2 , Figure 3 , wherein the card slot 2 has at least one of a first opening 21 and a second opening 22 ; the first opening 21 is arranged on the outer edge surface 11 , and the second opening 22 is arranged on one side of the buckling flap body 1 .

[0032] Specifically, the functions of the first opening 21 and the second opening 22 are to facilitate the entry of the card block 4 into the card slot 2 when the multiple snap-on flap bodies 1 are folded together; when the multiple snap-on flap bodies 1 are arranged in an arc shape and folded together, the card block 4 needs to enter the card slot 2 at an angle, and at this time, the card slot 2 needs to have the first opening 21 and the second opening 22 so that the card block 4 can smoothly enter the card slot 2; when the multiple snap-on flap bodies 1 can be arranged in a rectangular shape, the card slot 2 only has one of the first opening 21 and the second opening 22, which can also enable the card block 4 to smoothly enter the card slot 2.

[0033] It can be understood that in other embodiments, the block 4 can also be deformed into an inclined guide column, and the slot 2 can also be deformed into an inclined groove. When the multiple pressing flap bodies 1 are folded together, the cooperation between the inclined guide column and the inclined groove can also play a role in absorbing the errors of the multiple pressing flap bodies 1 and avoiding the occurrence of pressing marks.

[0034] Please continue reading Figure 2 , Figure 3 In some embodiments, the first opening 21 is arranged to communicate with the second opening 22, so that the card block 4 enters the card slot 2 from at least one of the first opening 21 and the second opening 22. This design makes the processing of the card slot 2 more convenient.

[0035] Please continue reading Figure 2 , Figure 4 , Figure 5 In some embodiments, when the block 4 of one snap-on flap body 1 is engaged with the slot 2 of another snap-on flap body 1, the block 4 abuts against the reserved portion 3, and the inner edge surfaces 12 of the two adjacent snap-on flap bodies 1 are on the same arc surface or plane.

[0036] Furthermore, the reserved portion 3 has a first abutting surface 31 arranged close to the card slot 2; the card block 4 has a second abutting surface 41 matching the first abutting surface 31; when the first abutting surface 31 and the second abutting surface 41 abut against each other, the inner edge surfaces 12 of the two adjacent retaining flap bodies 1 are on the same arc surface or plane.

[0037] It can be understood that when the block 4 of one pressing flap body 1 is engaged with the slot 2 of another pressing flap body 1, the reserved portion 3 has a limiting effect on the block 4. Under this limiting effect, the inner edge surfaces 12 of the two adjacent pressing flap bodies 1 are on the same arc surface or plane, so that the pressing depth is more consistent, thereby improving the pressing effect and aesthetics.

[0038] Please continue reading Figure 2 , Figure 4 , wherein the block 4 further has a fitting surface 42 ; the fitting surface 42 and the outer edge surface 11 are on the same arc surface or plane.

[0039] Under this arrangement, when the plurality of buckling flap bodies 1 are folded together, the clamping block 4 will not protrude from the clamping slot 2, thereby preventing the protruding clamping block 4 from being damaged by impact.

[0040] Please continue reading Figure 1 , Figure 2 , further includes at least one mounting hole 5 arranged on the buckling flap body 1, and the mounting hole 5 is used to connect the buckling flap body 1 and the power component, so that the power source drives the multiple buckling flap bodies 1 to be retracted and buckle the buckled product.

[0041] Please continue reading Figure 6 The air spring pressing tool shown includes the aforementioned pressing flap; a plurality of pressing flap bodies 1 are arranged in a circle so that a plurality of inner edge surfaces 12 form a circumferential surface for pressing the air spring.

[0042] When the air spring is actually compressed, the compressed part of the air spring is placed in a circular surface composed of multiple inner edge surfaces 12 of the compression petals. When the power source is working, the multiple compression petal bodies 1 are gathered toward the center of the circular surface to compress the compressed part of the air spring.

[0043] The above description is only for the best embodiment of the utility model, but it cannot be understood as a limitation of the claims. The utility model is not limited to the above embodiments, and its specific structure is allowed to be changed. All changes made within the protection scope of the independent claims of the utility model are within the protection scope of the utility model.
