Description

Technical Field

[0001] The present invention relates to the technical field of logistics and transportation, and in particular to a container connection component and a container. Background Art

[0002] Containers are important tools for sea-land transport. Generally, containers are surrounded by a bottom frame, side panels, end walls, doors and roof panels, and form a cargo space inside. During transportation, auxiliary accessories are usually required to be installed inside the container to meet the transportation requirements of some special goods. For example, in some refrigerated containers, an insulation curtain is usually required to be installed at one end near the door to minimize the heat transfer between the inside and outside of the container when the door is opened. In order to fix the insulation curtain, Velcro is usually installed on the lining plate or inner side plate on the side of the inside of the container, and the insulation curtain is fixed by Velcro. For another example, some containers need to have a horizontal cargo bar inside, and a fixing seat is connected to the side plate of the container, and the end of the cargo bar is clamped on the fixing seat. When installing auxiliary accessories such as Velcro and fixing seat inside the container, these auxiliary accessories are generally fixed to the side plates, lining plates and other panels by rivets. The position of the auxiliary accessories is fixed, and holes need to be punched in the panels to fix the rivets, which will affect the sealing of the container, especially for refrigerated containers.

[0029] Below, in conjunction with the accompanying drawings and specific embodiments, the present invention is further described:

[0030] like Figure 1 , 2As shown, a connection component of a container according to a first embodiment of the present invention is specifically a Velcro used inside a refrigerated container for fixing and bonding a thermal insulation curtain of the refrigerated container. Specifically, the connection component of the container includes a plate 10 and a fixing member 20. The plate 10 may be a rear lining plate of the refrigerated container. A groove 11 is provided on the plate 10. The groove 11 includes a bottom wall 15, a side wall 12, and a side wall 13. The groove 11 may be formed by bending the plate 10. Of course, the plate 10 may also be a profile, and the groove 11 is formed during molding. The side wall 12 and the side wall 13 are arranged opposite to each other, and are respectively located on both sides of the bottom wall 15. An opening 14 is formed between the side wall 12 and the end of the side wall 13 away from the bottom wall 15, and the opening 14 is arranged opposite to the bottom wall 15. A card slot 121 is arranged on the side wall 12, and two card slots 131 are arranged on the side wall 13. The extension directions of the card slots 121 and 131 are consistent with the extension direction of the groove 11, and the two card slots 131 are arranged in the depth direction of the groove 11. The card slot 121 and the two card slots 131 are arranged at intervals in the depth direction of the groove 11, and, in the depth direction of the groove 11, the distance between the card slot 121 and the two card slots 131 is equal, that is, in the depth direction of the groove 11, the card slot 121 is located between the two card slots 131, and the distance between the card slot 121 and the two card slots 131 is the same. A first clamping portion 1211 is formed on the inner wall of the card slot 121 close to the opening 14 of the groove 11, and a first clamping portion 1311 is formed on the inner wall of the card slot 131 close to the opening 14 of the groove 11. In this way, the extension direction of the first clamping portion 1211 and the two first clamping portions 1311 are consistent with the extension direction of the groove 11, and the two first clamping portions 1311 formed on the two card slots 131 are staggered in the depth direction of the groove 11, and the first clamping portion 1211 and the two first clamping portions 1311 are at the same distance apart in the depth direction of the groove 11.The fixing member 20 includes a cylindrical connecting portion 21 and a fastener. The diameter of the connecting portion 21 is slightly smaller than the distance between the side wall 12 and the side wall 13, so that the connecting portion 21 can be embedded in the groove 11 through the opening 14. The fastener is used to connect the auxiliary accessories to the connecting portion 21, specifically, to fix the Velcro used for bonding the thermal insulation curtain to the connecting portion 21; a pressing portion 211 is formed on the end surface of the connecting portion 21 close to the bottom wall 15 of the groove 11, and at the same time, a convex rib 212 is provided on the outer circumferential surface of the connecting portion 21. The convex rib 212 extends in a spiral shape on the outer circumferential surface of the connecting portion 21, and the arc of the projection of the convex rib 212 on the cross section of the connecting portion 21 The angle of the convex rib 212 is 360°, that is, the convex rib 212 just circles around the outer circumferential surface of the connecting portion 21, and the outer side wall of the convex rib 212 forms a second clamping portion 2123. The two ends of the convex rib 212 respectively form a first clamping portion 2121, and the middle part of the length direction of the convex rib 212 forms a second clamping portion 2122, wherein the two first clamping portions 2121 and the second clamping portion 2122 are respectively located on the outer side wall of the convex rib 212 (i.e., located on the second clamping portion 2123), wherein the two first clamping portions 2121 are respectively located at the two ends of the second clamping portion 2123, and the second clamping portion 2122 is located in the middle part of the length direction of the second clamping portion 2123. After the connecting portion 21 is inserted into the groove 11 through the opening 14 of the groove 11, it can rotate between a first position and a second position along the extension direction of the second clamping portion 2123, that is, the connecting portion 21 can rotate along the spiral extension direction of the convex rib 212. When the connecting part 21 rotates to the first position inside the groove 11, the clamping part 211 is pressed on the bottom wall 15 of the groove 11. At the same time, the two first clamping parts 2121 rotate with the connecting part 21 and are respectively placed in the two slots 131. At the same time, the second clamping part 2122 is just placed in the slot 121. In addition, when the clamping part 211 is pressed against the bottom wall 15, the second clamping part 2122 is pressed on the first clamping part 1211 on the slot 121. The two first clamping parts 2121 are respectively pressed on the first clamping parts 1311 on the two slots 131. In this way, the connecting part 21 is fixed inside the groove 11 through the cooperation between the clamping part 211 and the bottom wall 15, the cooperation between the second clamping part 2122 and the first clamping part 1211, and the cooperation between the two first clamping parts 2121 and the two first clamping parts 1311. When the connecting part 21 rotates to the second position inside the groove 11, the clamping part 211 is separated from the bottom wall 15 of the groove 11, the second clamping part 2122 is loosened from the first clamping part 1211, and the two first clamping parts 2121 are loosened from the two first clamping parts 1311 respectively. In this way, the connecting part 21 and the bottom wall 15, side wall 12 and side wall 13 of the groove 11 are all loosened. In this state, the connecting part 21 can be moved along the extension direction of the groove 11.

[0031] See also Figure 3As shown, when the fixing member 20 of the present invention is fixed to the plate 10, the pressing portion 211 on the connecting portion 21 is aligned with the opening 14 of the groove 11, and the two first clamping portions 2121 at both ends of the rib 212 are facing upward (i.e., perpendicular to the paper and outward), the rib 212 is against the opening 14 of the groove 11, and the connecting portion 21 is rotated clockwise, as shown in FIG. Figure 4 As shown, the spiral rib 212 is guided by the opening 14 of the groove 11, so that the first clamping portion 2121 of the rib 212 near the bottom wall 15 is clamped into the clamping groove 131 near the opening 14 after the connection portion 21 rotates. At this time, the connection portion 21 is further rotated 360° in the clockwise direction. Figure 5 As shown, the first clamping portion 2121 close to the bottom wall 15 is clamped in the clamping groove 131 close to the bottom wall 15, and at the same time, the other first clamping portion 2121 is just clamped into the clamping groove 131 close to the opening 14, and the second clamping portion 2122 is just located in the first clamping groove 121. When the connecting portion 21 is rotated clockwise by a small angle, the clamping portion 211 presses the bottom wall 15, and the two first clamping portions 2121 respectively press the first clamping portions 1311 of the two clamping grooves 131, and the second clamping portion 2122 presses the first clamping portion 1211 of the clamping groove 121, that is, the connecting portion 21 is rotated to the above-mentioned first position, thereby fixing the connecting portion 21 in the groove 11. When the position of the connecting part 21 needs to be adjusted along the length direction of the groove 11, the connecting part 21 is rotated counterclockwise to separate the pressing part 211 from the bottom wall 15. At this time, the two first clamping parts 2121 are separated from the two first clamping parts 1311 respectively, and the second clamping part 2122 is separated from the first clamping part 1211. The convex rib 212 is no longer pressed and matched with the clamping groove 121 and the clamping groove 131, so that the part of the convex rib 212 located in the clamping groove 121 and the clamping groove 131 has the freedom to move along the length direction of the clamping groove 121 and the clamping groove 131. When the connecting part 21 is adjusted to a proper position along the length direction of the clamping groove 121 and the clamping groove 131, the connecting part 21 is tightened clockwise to fix the connecting part 21 in the groove 11 again. Compared with the prior art, the fixing member of the present invention is fixed in the groove opened on the plate by rotation. When the auxiliary accessories are installed on the plate, it is not necessary to open a hole on the plate, and the position of the fixing member can be adjusted at will in the extension direction of the groove.

[0032] In order to facilitate the insertion of the rib 212 into the slots 121 and 131, the width of the slots 121 and 131 in the present invention is slightly larger than the width of the rib 212, that is, when the rib 212 is inserted into the first slot 121 and the second slot 131, there is a certain gap between the two sides of the rib 212 and the slots 121 and 131, so that the connection part 21 can be easily rotated. When the pressing part 211 presses the bottom wall 15, the bottom wall 15 applies a thrust force toward the opening 14 to the connection part 21, so that the rib 212 can press the inner wall of the slots 121 and 131 on the outside toward the side of the opening 14, so that the connection part 21 remains fixed. In order to further facilitate the installation of the connection part 21, the present invention sets the cross-section of the slots 121 and 131 to be V-shaped, and at the same time, the cross-section of the rib 212 is also set to be V-shaped.

[0033] In addition, in the above scheme, the distance between the two slots 131 on the side wall 13 is equal to the pitch of the convex rib 212. At the same time, since the distance between the slot 121 on the side wall 12 and the two slots 131 in the depth direction of the groove 11 is equal, the two first clamping portions 2121 on the convex rib 212 respectively press the first clamping portions 1311 on the two slots 131, while the second clamping portion 2122 in the middle of the length direction of the convex rib 212 presses the first clamping portion 1211 on the slot 121.

[0034] The arc of the projection of the rib 212 on the cross section of the connecting portion 21 can not only be set to the above-mentioned 360°, but in fact, the arc of the projection of the rib 212 on the cross section of the connecting portion 21 can also be set to 720°, that is, the rib 212 surrounds the outer circumferential surface of the connecting portion 21 twice, that is, the second clamping portion 2123 surrounds the outer circumferential surface of the connecting portion 21 twice, and correspondingly, three clamping grooves 131 can be set on the side wall 13, and two clamping grooves 121 can be set on the side wall 12, and the two ends of the rib 212 in the length direction are , and a first clamping portion 2121 is respectively formed in the middle of the length direction, and a second clamping portion 2122 is respectively formed at the middle position of two adjacent first clamping portions 2121 on the convex rib 212. Thus, three first clamping portions 2121 and two second clamping portions 2122 are formed on the convex rib 212. The three first clamping portions 2121 are respectively clamped and matched with the first clamping portions 1311 on the three clamping grooves 131, and the two second clamping portions 2122 are respectively clamped and matched with the first clamping portions 1211 on the two clamping grooves 121. Of course, the arc of the projection of the convex rib 212 of the present invention on the cross section of the connecting portion 21 can also be set to be less than 360°. For example, the arc of the projection of the convex rib 212 on the cross section of the connecting portion 21 is 270°. Correspondingly, a clamping groove 121 is set on the side wall 12, and a clamping groove 131 is set on the side wall 13. The first clamping portion 2121 is located at one end of the convex rib 212, and the second clamping portion 2122 is located on the convex rib 212 at a position 180° apart from the first clamping portion 2121 by an arc. In summary, since the slots 121 and 131 are respectively located on both sides of the connecting portion 21 after the connecting portion 21 is embedded in the groove 11, the angle of the convex rib 212 on the connecting portion 21 should be greater than 180°, that is, the arc of the projection of the second clamping portion 2123 on the convex rib 212 on the cross-section of the connecting portion 21 is greater than 180 degrees, so that the convex rib 212 has a portion that is embedded in the slots 121 and 131 at the same time, so that the convex rib 212 can press the slots 121 and 131 at the same time.

[0035] The above-mentioned fastener can be a fastening screw 22, which is screwed on one end of the connecting part 21 away from the clamping part 211. The fastening screw 22 can be used to fix the Velcro 30 on the connecting part 21, and then the Velcro 30 is fixed to the plate 10 through the cooperation between the connecting part 21 and the groove 11.

[0036] Figure 6The connecting assembly of the container of the second embodiment of the present invention is shown, which includes a plate 40 and a fixing member 50. A groove 41 is arranged on the plate 40. The groove 41 includes a bottom wall 45, a side wall 42, and a side wall 43. The side wall 42 and the side wall 43 are arranged opposite to each other. The two are respectively located on both sides of the bottom wall 45, and an opening 44 is formed between the side wall 42 and the end of the side wall 43 away from the bottom wall 45. The opening 44 is arranged opposite to the bottom wall 45. The fixing member 50 includes a connecting portion 51 and a fastener, wherein the connecting portion 51 is cylindrical in structure, and its diameter is slightly smaller than the distance between the side wall 42 and the side wall 43, so that the connecting portion 51 can be embedded in the groove 41 through the opening 44. A pressing portion 511 is formed on one end surface of the connecting portion 51 close to the bottom wall 45 of the groove 41, and a pit 512 is provided on the outer circumferential surface of the connecting portion 51, and the pit 512 extends in a spiral shape on the outer circumferential surface of the connecting portion 51. A convex rib 421 is provided on the side wall 42, and a convex rib 431 is provided on the side wall 43. The extending directions of the convex rib 421 and the convex rib 431 are consistent with the extending direction of the groove 41, and the convex rib 421 and the convex rib 431 are staggered from each other in the depth direction of the groove 41, and the staggered distance between the two is half of the pitch of the pit 512; the wall surface of the convex rib 421 away from the opening 44 of the groove 41 forms a first clamping portion 4211, and the convex rib The wall surface on the side away from the opening 44 of the groove 41 forms a first clamping portion 4311, and the inner wall of the side of the pit 512 away from the opening 44 of the groove 41 forms a second clamping portion. The second clamping portion is provided with a first clamping portion 5121 and a second clamping portion 5122. The arc of the first clamping portion 5121 and the second clamping portion 5122 in the circumferential direction of the connecting portion 51 is staggered by 180°, that is, the distance of the staggered distance between the two in the axial direction of the connecting portion 51 is half of the pitch of the pit 512. When the fixing member 50 is fixed to the plate member 40, the connecting portion 51 is placed at the opening 44 of the groove 41, and the connecting portion 51 is rotated so that the convex ribs 421 and the convex ribs 431 are embedded. In the pit 512, when the pressing part 511 presses against the bottom wall 45 of the groove 41, the connecting part 51 rotates to the first position, at which time the first clamping part 5121 presses the first clamping part 4311 toward the opening 44, and the second clamping part 5122 presses the first clamping part 4211 toward the opening 44, so that the connecting part 51 is fixed in the groove 41. When the connecting part 51 needs to be moved along the length direction of the groove 41, the connecting part 51 is rotated in the opposite direction to separate the pressing part 511 from the bottom wall 45 of the groove 41, the first clamping part 5121 is loosened from the first clamping part 4311, and the second clamping part 5122 is loosened from the first clamping part 4211, so that the connecting part 51 can be moved. In order to facilitate the installation of the connecting part 51, the cross-sections of the pit 512, the ribs 431 and the ribs 421 are all set to be V-shaped.
