[0023] The following detailed description will further describe the present application with reference to the above-mentioned drawings. DETAILED DESCRIPTION

[0024] In order to enable a more clear understanding of the above-mentioned purposes, features and advantages of the embodiments of the present application, the present application will be described in detail below with reference to the drawings and specific embodiments. It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0025] In the following description, many specific details are set forth in order to fully understand the embodiments of the present application. The described embodiments are merely a part of the embodiments of the present application, and are not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the embodiments of the present application.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the embodiments of the present application belong. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the embodiments of the present application.

[0027] Please refer to Figure 1 The present application provides a screw structure 100, which comprises a nut 10, a screw rod 20 and an elastic component 30. The screw rod 20 comprises a threaded portion 21 and an engaging portion 22, and the engaging portion 22 is connected between the nut 10 and the threaded portion 21. The elastic component 30 is a hollow annular structure. The elastic component 30 is provided with an opening 30a penetrating through the elastic component 30 along the radial direction of the elastic component 30, and the elastic component 30 is used for clamping the engaging portion 22. In the present embodiment, the outer periphery of the threaded portion 21 is provided with external threads, and the outer periphery of the engaging portion 22 is not provided with external threads.

[0028] The screw structure 100 can be used for screwing storage containers. The storage container includes an upper cover and a lower cover, which are combined to store workpieces. When the screw structure 100 is applied to the screwing between the upper cover and the lower cover, the upper cover has a hole for the screw rod 20 to pass through, the lower cover has a hole for accommodating the threaded portion 21, and the inner wall of the hole of the lower cover has internal threads coupled with the threaded portion 21. The screw rod 20 of the screw structure 100 is passed through the hole of the upper cover, the elastic member 30 is then looped around the engaging portion 22, and then the screw rod 20 is screwed into the hole in the lower cover. The upper cover and the lower cover are screwed, and the elastic member 30 is compressed between the upper cover and the lower cover under external force. When the screw rod 20 is unscrewed from the lower cover and completely separated from the lower cover, the elastic member 30 engaged with the engaging portion 22 blocks the screw rod 20 from being separated from the upper cover, so that the screw structure 100 is relatively fixed to the upper cover and does not fall off from the hole of the upper cover.

[0029] In some embodiments, the outer diameter of the threaded portion 21 is greater than the inner diameter of the elastic member 30, so that the elastic member 30 is not easy to slip off from one end of the threaded portion 21 of the screw structure 100, further reducing the probability of the screw structure 100 falling off from the hole of the upper cover.

[0030] In some embodiments, the elastic member 30 is in interference fit with the engaging portion 22. In this embodiment, the inner diameter of the elastic member 30 can be slightly smaller than the outer diameter of the engaging portion 22, so that the elastic member 30 can be more firmly engaged with the outer periphery of the engaging portion 22, and a greater external force is not required to make the elastic member 30 slide relative to the engaging portion 22 to combine the upper cover and the lower cover during the combination of the upper cover and the lower cover.

[0031] In some embodiments, the elastic member 30 can be a circlip, a retaining ring, or other parts that have relatively two free ends that can be opened and engaged with the engaging portion 22. In this embodiment, the elastic member 30 is a circlip, and a through hole 31 is formed in the middle of the circlip. The opening 30a is in communication with the through hole 31, and the through hole 31 provides the space required for the circlip to be engaged with the engaging portion 22. The circlip is engaged with the engaging portion 22 by opening the free ends of the circlip at both ends of the opening 30a.

[0032] In some embodiments, the outer diameter of the engaging portion 22 is smaller than the outer diameter of the threaded portion 21. Generally, the outer diameter of the screw rod 20 of the screw structure 100 is greater than the inner diameter of the standard circlip, so that the standard circlip is not easy to be engaged with the screw. Reducing the outer diameter of the engaging portion 22 can make the screw structure 100 more easily match the inner diameter of the standard circlip, without the need for additional customization of the circlip to match the outer diameter of the screw rod 20 of the screw structure 100.

[0033] In some embodiments, the surface of the nut 10 away from the engaging portion 22 is provided with a recess 12, and the recess 12 is in the shape of a cross. In other embodiments, the recess 12 can be in the shape of a straight line, a square, a hexagon, or other shapes.

[0034] Referring to Figure 2 In some embodiments, the present application further provides another screw structure 100a, which is different from the screw structure 100 in that, in the screw structure 100a, the outer circumferential surface of the engaging portion 22 is provided with an annular engaging groove 22a along the circumferential direction of the engaging portion 22, and the engaging groove 22a is used to accommodate the elastic member 30. The engaging groove 22a helps to reduce the risk of the elastic member 30 falling off from the engaging portion 22.

[0035] In some embodiments, the inner diameter of the engaging groove 22a matches the inner diameter of the elastic member 30, and the elastic member 30 is clamped in the engaging groove 22a. For example, the inner diameter of the engaging groove 22a can be the same as the inner diameter of the elastic member 30, or the inner diameter of the elastic member 30 can be slightly smaller than the inner diameter of the engaging groove 22a, so that the elastic member 30 is in interference fit with the engaging groove 22a.

[0036] Referring to Figure 3 The present application further provides a carrier 200, which comprises the screw structure 100, a carrier body 40, and a cover 50. The cover 50 is provided with a first mounting hole 50a, and the engaging portion 22 of the screw structure 100 passes through the first mounting hole 50a. The carrier body 40 is provided with a second mounting hole 41, and the threaded portion 21 and the elastic member 30 of the screw structure 100 are accommodated in the second mounting hole 41. The cover 50 is located between the elastic member 30 and the nut 10, and the outer diameter of the elastic member 30 is greater than the hole diameter of the first mounting hole 50a. The outer diameter of the elastic member 30 is greater than the hole diameter of the first mounting hole 50a, so that the elastic member 30 can clamp the screw rod 20 to prevent the screw rod 20 from falling out of the first mounting hole 50a.

[0037] In some embodiments, the second mounting hole 41 comprises a first through hole 41a and a second through hole 41b, the first through hole 41a communicates with the second through hole 41b, the diameter of the first through hole 41a matches the diameter of the threaded portion 21, and the diameter of the second through hole 41b matches the outer diameter of the elastic member 30. The first through hole 41a is used to accommodate the screw rod 20, and the second through hole 41b is used to accommodate the elastic member 30, so that when the cover 50 and the carrier body 40 are screwed, the cover 50 and the carrier body 40 can be tightly covered.

[0038] In some embodiments, the cover 50 is provided with a through slot 51, the through slot 51 penetrates through the opposite surfaces of the cover 50 and penetrates through one end edge of the cover 50. When the cover 50 is covered with the carrier body 40, part of the carrier body 40 is exposed from the through slot 51. The through slot 51 facilitates picking up the cover 50 from the surface of the carrier body 40.

[0039] In some embodiments, the carrier body 40 comprises a first side plate 42, a second side plate 43, a third side plate 44, a fourth side plate 45 and a bottom plate 47. The third side plate 44 is connected between the first side plate 42 and the second side plate 43. The fourth side plate 45 is connected between the first side plate 42 and the second side plate 43 and opposite to the third side plate 44. The first side plate 42, the second side plate 43, the third side plate 44, the fourth side plate 45 and the bottom plate 47 jointly enclose a receiving cavity 46 for receiving a workpiece. The first side plate 42 and the second side plate 43 are respectively provided with a first groove 42a and a second groove 43a on a side away from the receiving cavity 46. The first groove 42a penetrates part of the first side plate 42. The second groove 43a penetrates part of the second side plate 43. The first groove 42a and the second groove 43a are used to prevent slipping when the carrier body 40 is picked up.

[0040] In some embodiments, the outer side of the first side plate 42 can be provided with a plurality of first grooves 42a arranged in parallel with each other. The outer side of the second side plate 43 can be provided with a plurality of second grooves 43a arranged in parallel with each other. The plurality of first grooves 42a and the plurality of second grooves 43a can further enhance the anti-slip effect.

[0041] The above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the present application.
