Description

Box structure

Technical Field

The invention relates to an elastic ring and a box body structure, in particular to an O-shaped elastic ring and a box body structure for a cover-lifting type box body.

Background

The cover-lifting type box body is provided with a base and an upper cover, the base and the upper cover can be connected through a solid pin and an elastic ring, and the solid pin is arranged in the elastic ring in a penetrating manner. When the upper cover is opened, the elastic ring is rubbed and pressed by the solid pin, so that resistance can be provided to stop the upper cover at any angle. However, the elastic ring is easily worn by friction, so that the stopping effect of the upper cover gradually decreases as the number of times of opening and closing increases.

In view of this, how to improve the above-mentioned problems to increase the service life of the elastic ring and the cover-lifting type box is an issue to be solved by related industries.

Detailed Description

Referring to fig. 1, 2 and 3, fig. 1 is a schematic perspective view of an O-ring 100 according to a first embodiment of the present invention, fig. 2 is a schematic side sectional view of the O-ring 100 of the first embodiment of fig. 1 received in a hole H1, and fig. 3 is a schematic side sectional view of the O-ring 100 of the first embodiment of fig. 1 received in the hole H1 and configured for inserting a rotating shaft P1. The O-ring 100 is disposed in the hole H1 and cooperates with the rotating shaft P1, and the O-ring 100 includes an inner wall 110, an outer wall 120, at least one inner protrusion 130, and at least one outer recess 140. The inner wall 110 defines a penetrating space S1 for the shaft P1 to penetrate, and the outer wall 120 is opposite to the inner wall 110. The inner protrusion 130 is located on the inner wall 110 and protrudes toward the penetrating space S1, and the outer recess 140 is located on the outer wall 120 and provides a space for the inner protrusion 130 to deform radially outward.

Therefore, the outer concave portion 140 provides a deformation space, the inner convex portion 130 has enough space deformation after being pushed by the rotating shaft P1, friction loss can be reduced when the rotating shaft P1 is provided with contact force, and service life can be prolonged. Details of the O-ring 100 will be described in more detail later.

The O-ring 100 is a one-piece structure made of an elastic material, so that the O-ring 100 is deformable after being pressed. As shown in fig. 1, the number of the inner protrusions 130 may be plural, and the inner protrusions 130 may be disposed at intervals on the inner wall 110. The number of the outer concave portions 140 is also plural, the outer concave portions 140 are disposed on the outer wall 120 at intervals, and each inner convex portion 130 at least partially corresponds to each outer concave portion 140.

Specifically, as shown in fig. 1 and 2, the number of the inner protrusions 130 and the outer recesses 140 may be the same, the number of the inner protrusions 130 and the outer recesses 140 is five, and the inner protrusions 130 and the outer recesses 140 are arc-shaped. When the O-ring 100 is formed, five inner protrusions 130 and five outer recesses 140 can be integrally formed by the change of the inner diameter and the change of the outer diameter, the diameter of a virtual circle surrounded by the apexes of the inner protrusions 130 is smaller than that of the inner wall 110, the diameter of a virtual circle surrounded by the pits of the outer recesses 140 is also smaller than that of the outer wall 120, the center line I1 of each inner protrusion 130 is collinear with the center line I2 of each outer recess 140, and the center O1 of the O-ring 100 allows each inner protrusion 130 and each outer recess 140 to completely correspond. In other embodiments, the center line of each inner convex portion and the center line of each outer concave portion may not be collinear, and preferably still have partial areas corresponding to each other, so as to provide a preferred outward deformation space for the inner convex portion.

As shown in fig. 3, when the O-ring 100 is disposed in the hole H1, the outer wall 120 may abut against the wall of the hole H1, and when the rotating shaft P1 is inserted into the through space S1, the rotating shaft P1 directly contacts the inner protrusion 130 and presses the inner protrusion 130, so that the inner protrusion 130 deforms in the radial direction. Since the outer side of the inner convex portion 130 corresponds to the outer concave portion 140, a gap is provided between the outer concave portion 140 and the hole wall, and the inner convex portion 130 can be deformed with a space.

The case structure 200 comprises a base 210, an upper cover 220, at least one shaft 240, and at least one O-ring 230. The base 210 includes at least one first plugging hole 211, the upper cover 220 is covered on the base 210 and includes at least one second plugging hole 221, and the second plugging hole 221 corresponds to the first plugging hole 211. The rotating shaft 240 is inserted into the first inserting hole 211 and the second inserting hole 221 to connect the base 210 and the upper cover 220.

The O-ring 230 is accommodated in one of the first plug hole 211 and the second plug hole 221, and the O-ring 230 includes an inner wall (not labeled in the second embodiment), an outer wall (not labeled in the second embodiment), at least one inner protrusion 231 and at least one outer recess 232. The inner wall defines a penetrating space S1 for the shaft 240 to penetrate, and the outer wall is opposite to the inner wall. The inner protrusion 231 is located on the inner wall and protrudes toward the penetrating space S1, the outer recess 232 is located on the outer wall and corresponds to the inner protrusion 231, and the outer recess 232 provides a space for the radially outward deformation of the inner protrusion 231.

Specifically, the base 210 may include a receiving space for placing the object, and the upper cover 220 may cover the receiving space with respect to the base 210 or may be lifted for picking up the object. The number of the first inserting holes 211, the number of the second inserting holes 221, the number of the rotating shafts 240 and the number of the O-shaped elastic rings 230 are two, and each O-shaped elastic ring 230 is accommodated in each second inserting hole 221. The two first plugging holes 211 are disposed at intervals on the upper edge of the base 210, and the base 210 further comprises two grooves 212, each groove 212 is communicated with each first plugging hole 211, the upper cover 220 further comprises two protruding blocks 222, the two protruding blocks 222 are disposed at intervals on the inner edge of the upper cover 220, each protruding block 222 is correspondingly accommodated in each groove 212, and each second plugging hole 221 penetrates through each protruding block 222. Therefore, after each of the rotating shafts 240 is inserted into each of the O-rings 230 and each of the first insertion holes 211, the upper cover 220 can be connected to the base 210.

The structure of the O-ring 230 is the same as the O-ring 100 of the first embodiment, and details thereof will not be repeated. The rotating shaft 240 may include a head portion 241, a ring gear portion 242, and a smooth shaft portion 243, wherein the head portion 241 is exposed from the first inserting hole 211, and the ring gear portion 242 is connected to the head portion 241 and located in the first inserting hole 211. The smooth shaft portion 243 is connected to the ring tooth portion 242, and is configured to be inserted into the through space S1 of the O-ring 230, and push against each inner protrusion 231 of the O-ring 230, so as to increase the stability of connection.

Referring to fig. 6 and 7, fig. 6 is a schematic side cross-sectional view of the case structure 200 of the second embodiment of fig. 4, and fig. 7 is a schematic side cross-sectional view of the case structure 200 of the second embodiment of fig. 4. By the structure of the O-ring 230, a certain contact force of the rotating shaft 240 is provided to form a resistance, so that the upper cover 220 maintains a positional relationship with the base 210 without external force. Therefore, the upper cover 220 can be stopped at any rotation angle position, such as the position of fig. 6 or the position of fig. 7, relative to the base 210 during the opening or closing process, and the O-ring 230 still has room to deform relatively while providing the contact force, so as to greatly reduce the friction loss and increase the service life, and provide a stable contact force.
