Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connector and a rotating shaft having the same. Background Art

[0002] In modern industry and engineering, joints, as a mechanical device that connects different parts or components, play a vital role.

[0003] Traditional joints are usually welded to different components. For example, the joint of the shaft is often welded directly to the shaft, and then the expansion components are connected to the joint. Figure 1 A conventional rotating shaft for a magic door shown in FIG. has welded joints at both ends. To obtain a shaft of different lengths, the shaft must be cut into three sections, the excess shaft removed, and then the two welded joints welded together. Shafts with these fixed joints must be cut and re-welded to change length, which not only increases operational complexity but also potentially wastes material and reduces structural strength.

[0030] The following description of the present invention, with reference to the accompanying drawings, is provided to facilitate a more comprehensive understanding of the various embodiments of the present invention as defined in the claims and their equivalents. The description includes various specific details to assist understanding, but these details should be construed as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0031] In the description of the present invention, descriptions of directions, such as up, down, front, back, left, right, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0032] It will be understood that when one element (e.g., a first element) is “connected” to another element (e.g., a second element), the element may be directly connected to the other element or an intervening element (e.g., a third element) may be present between the element and the other element.

[0033] The embodiment of the first aspect of the present utility model provides a connector, such as Figure 2-8 Shown, including:

[0034] The connector body 100 includes a connector 200 and a first connector 300 and a second connector 400 locked by the connector 200. An adjustment structure 120 is provided between the first connector 300 and the second connector 400. When the connector 200 locks the first connector 300 and the second connector 400, under the action of the adjustment structure 120, the second connector 400 moves relative to the first connector 300 and forms a misalignment.

[0035] The connector 200 is a component used to fasten the first and second connecting parts 300 and 400 together. It can be a fastener, such as a bolt, screw, or clamp. The first and second connecting parts 300 and 400 can be cylindrical, square, or other shapes. When the connector 200 fastens the first and second connecting parts 300 and 400, the adjustment structure 120 causes the second connecting part 400 to move relative to the first connecting part 300 and become dislocated.

[0036] Specifically, when using this connector, the connector body 100 is first placed into the component to be connected, and then the first connecting part 300 and the second connecting part 400 are locked by the connecting member 200. Under the action of the adjustment structure 120, the second connecting part 400 will move relative to the first connecting part 300, causing the first connecting part 300 and the second connecting part 400 to be misaligned. The first connecting part 300 and the second connecting part 400 are tightly matched with the inner wall of the component to be connected, completing the fixation of the connector body 100. This connector structure can achieve detachable fixation with the component to be connected, and the connector can be directly removed when the component to be connected needs to be replaced.

[0037] Example 1: The adjustment structure 120 is a first inclined portion 310 provided on the first connecting portion 300 and a second inclined portion 410 provided on the second connecting portion 400. When the connecting member 200 locks the first connecting portion 300 and the second connecting portion 400, under the action of the first inclined portion 310 and the second inclined portion 410, the second connecting portion 400 moves relative to the first connecting portion 300 and forms a misalignment.

[0038] Example 2: The adjustment structure 120 is a hinge structure connecting the first connection part 300 and the second connection part 400. When the connecting member 200 locks the first connection part 300 and the second connection part 400, the hinge enables the second connection part 400 to move around a fixed point or axis and be misaligned with the first connection part 300.

[0039] Example 3: The adjustment structure 120 is a rack provided on the first connecting part 300 and a gear provided on the second connecting part 400. The gear and the rack are engaged with each other. When the connecting member 200 locks the first connecting part 300 and the second connecting part 400, the gear moves on the rack, thereby causing the first connecting part 300 and the second connecting part 400 to be misaligned.

[0040] In some embodiments, the adjustment structure 120 is a first inclined portion 310 provided on the first connection portion 300 and a second inclined portion 410 provided on the second connection portion 400. When the connecting member 200 locks the first connection portion 300 and the second connection portion 400, under the action of the first inclined portion 310 and the second inclined portion 410, the second connection portion 400 moves relative to the first connection portion 300 and forms a misalignment.

[0041] Due to the action of the first inclined portion 310 and the second inclined portion 410, the second connecting portion 400 moves relative to the first connecting portion 300, forming a staggered fixed state. Specifically, the first inclined portion 310 and the second inclined portion 410 are inclined surfaces.

[0042] In some embodiments, a through hole 320 for the connecting member 200 to pass through is defined in the first connecting portion 300 , and the end of the connecting member 200 connected to the second connecting portion 400 can move radially toward the through hole 320 .

[0043] The first connecting portion 300 defines a through-hole 320, through which the connecting member 200 passes and locks the first connecting portion 300 with the second connecting portion 400. The end of the connecting member 200 connected to the second connecting portion 400 is designed to move radially in the through-hole 320. This design allows the connecting member 200 to move freely within the through-hole 320, so that when the second connecting portion 400 is displaced relative to the first connecting portion 300, the connecting member 200 can move with the second connecting portion 400.

[0044] In some embodiments, the radial movement of the connecting member 200 toward the through hole 320 can be achieved by increasing the size of the through hole 320 at one end where the connecting member 200 is connected to the second connecting portion 400 .

[0045] Furthermore, the connecting member 200 is a bolt, and the first connecting portion 300 includes a first limiting portion 330 for limiting the passage of the bolt head.

[0046] The use of bolts allows for easy assembly and disassembly of the connection components when needed, adapting to different application requirements. The first connection portion 300 is designed with a first stopper 330, which functions to restrict the passage of the bolt head. Specifically, the first stopper 330 is a circular ring that restricts the passage of the bolt head. This design ensures that the bolt does not completely pass through the first connection portion 300 during the fastening process, thereby maintaining a stable and secure connection.

[0047] Furthermore, the second connecting portion 400 is provided with a threaded hole that cooperates with the connecting member 200 .

[0048] The second connecting portion 400 is designed with threaded holes that match the threads of the bolts. This design allows the bolts to securely fasten the second connecting portion 400 through a threaded connection. The first stopper 330 cooperates with the threaded holes, allowing the bolts to continuously tighten the first connecting portion 300 and the second connecting portion 400 while being screwed into the second connecting portion 400.

[0049] In some embodiments, the first connecting portion 300 includes a second limiting portion 340 for limiting the connector body 100 from being fully inserted into the component to be connected.

[0050] The first connecting portion 300 includes a second stopper 340 for limiting the full insertion of the connector body 100 into the component to be connected. Specifically, the second stopper 340 is a raised ring that limits the full insertion of the connector body 100. This design feature ensures that the connector body 100 does not over-insert or move during installation, thereby ensuring accurate and safe installation.

[0051] Furthermore, the second limiting portion 340 includes a mounting structure 350 for mounting the expansion component 600 .

[0052] By integrating the mounting structure 350 on the second limiting portion 340 , the joint can not only limit the movement of the body but also provide an additional mounting point, thereby increasing the versatility of the joint.

[0053] Furthermore, the protrusion structure includes a protrusion located on the surface of the second limiting portion 340 .

[0054] The surface of the second limiting portion 340 is provided with bumps, which are a specific form of a raised structure for mounting the expansion component 600. The bumps can be round, square or other shapes to meet different installation requirements.

[0055] Furthermore, there are two protrusions that are arranged opposite to each other, and the connection direction of the two protrusions is perpendicular to the extension direction of the positioning groove 110. The perpendicular design can increase the connection strength between the connector and the component to be connected.

[0056] In some embodiments, both the first connection portion 300 and the second connection portion 400 are provided with a positioning groove 110 , and the two positioning grooves 110 are connected to each other.

[0057] Furthermore, there are two positioning grooves 110 , and the two positioning grooves 110 are oppositely arranged on the surface of the connector body 100 .

[0058] The relative arrangement of the two positioning grooves 110 means that their positions on the connector body 100 are symmetrical, which helps to ensure balance and stability when installing or aligning components.

[0059] In some embodiments, the first inclined portion 310 and the second inclined portion 410 are formed by integrally molding the first connecting portion 300 and the second connecting portion 400 and then cutting them obliquely.

[0060] The embodiment of the second aspect of the present utility model provides a rotating shaft, such as Figure 5-8 As shown, a connector including the embodiment of the first aspect mentioned above further includes a shaft body 500 , and the connector body 100 is inserted into the shaft body 500 .

[0061] The connector is detachably connected to the shaft body 500. When the shaft is too long, it is only necessary to remove the connector, cut the shaft into a suitable length, and then install the connector.

[0062] Specifically, when applying the rotating shaft, the joint body 100 is first placed in the rotating shaft body 500, and then the first connecting part 300 and the second connecting part 400 are locked by the connecting member 200. Under the action of the adjustment structure 120, the second connecting part 400 will move relative to the first connecting part 300, so that the first connecting part 300 and the second connecting part 400 are misaligned. The first connecting part 300 and the second connecting part 400 are tightly matched with the inner wall of the rotating shaft body 500 to complete the fixation of the joint body 100.

[0063] Furthermore, both the first connecting portion 300 and the second connecting portion 400 are provided with a positioning groove 110 , and the two positioning grooves 110 are connected to each other. A positioning protrusion 510 matching the positioning groove 110 is provided in the rotating shaft body 500 .

[0064] The shaft body 500 is equipped with positioning ridges 510 that mate with the locating grooves 110 of the connector. These positioning ridges 510 interact with the locating grooves 110 of the connector to ensure precise alignment and securement between the shaft and the connector. They also provide precise positioning for other components, such as the position of the structure for mounting other components. The matching design of the positioning ridges 510 and the locating grooves 110 ensures precise alignment between the shaft and the connector, which is crucial for ensuring smooth operation of the shaft and reducing wear.

[0065] In some embodiments, the inner periphery of the shaft body 500 is a non-circular contour, and the outer periphery of the joint body 100 matches the inner periphery of the shaft body 500 .

[0066] The inner periphery of the shaft body 500 is a non-circular contour, which can be an ellipse, a D-shape, a triangle, a quadrilateral or other shapes. The outer periphery of the joint body 100 matches the inner periphery of the shaft body 500, that is, the place where the joint body 100 and the shaft body 500 are plugged in is a non-circular contour. The shape of the outer periphery of the shaft body 500 can be any shape, that is, the contours of the outer periphery of the shaft body 500 and the inner periphery of the shaft body 500 can be the same or different, such as Figure 8 As shown, the inner periphery of the shaft body 500 is triangular, the outer periphery of the shaft body 500 is circular, and the outer periphery of the joint body 100 is triangular; Figure 9 As shown, the inner periphery of the rotating shaft body 500 is a quadrilateral, the outer periphery of the rotating shaft body 500 is circular, and the outer periphery of the joint body 100 is a quadrilateral; since the outer periphery of the joint body 100 and the inner periphery of the rotating shaft body 500 are both non-circular contours, the joint body 100 can be positioned according to the inner periphery shape of the rotating shaft body 500, and the rotating shaft body 500 can be driven to move synchronously when the joint body 100 rotates.

[0067] The terms and words used in the above description and claims are not limited to their literal meanings, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the present invention is provided for illustration only and is not intended to limit the present invention as defined in the appended claims and their equivalents.
