Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, based on the examples herein, which are within the scope of the invention as defined by the claims, will be within the scope of the invention as defined by the claims.
The technical scheme of the invention is described in detail below with reference to the accompanying drawings.
An auxiliary connector comprises a connecting sleeve 2, a loop and a pressing sleeve 1 with conical surfaces on the outer wall of the connecting sleeve 2,
at least one containing hole for containing the pressing bead 3 is formed in the pipe wall of the connecting sleeve 2 close to the large-diameter end of the pressing sleeve 1, and when the small-diameter end of the pressing sleeve 1 moves towards the pressing bead 3, the pressing bead 3 extending out of the outer wall surface of the connecting sleeve 2 is in rolling fit with the inner wall of the pressing sleeve 1, and the pressing bead 3 extending out of the inner wall of the connecting sleeve 2 is in rolling fit with the rod part of the rivet 5 inserted into the connecting sleeve 2.
Taking the operation of the upper bead 3 shown in fig. 2 as an example: during operation, the rivet 5 sequentially penetrates through the accessory and the frame main beam, then penetrates into the connecting sleeve 2, then pushes the pressing sleeve 1, and the conical surface in the pressing sleeve 1 presses the pressing bead 3 while the pressing bead 3 rolls, so that the lower part of the pressing bead 3 moves downwards and contacts with the rod part of the rivet 5 and is clamped, and the rod part of the rivet 5 is pressed by the pressing bead 3 so that the rivet 5 cannot move along the axial direction. Of course, the auxiliary connector provided by the invention can be suitable for connection of the frame main beam and the accessory, and is also suitable for other fields needing temporary connection.
In order to enable the rivet 5 to lock the pressing sleeve 1 after being clamped by the pressing bead 3 so that the rivet cannot relatively displace on the axis, the invention particularly provides a locking structure, which comprises the following steps: the outer wall of the connecting sleeve 2 close to the small diameter end of the compression sleeve 1 is provided with at least one L-shaped chute 6, each chute 6 is symmetrically arranged by taking the axis of the connecting sleeve 2 as the center, the length direction of one side of the chute 6 is parallel to the axis of the connecting sleeve 2, the length direction of the other side of the chute 6 is equal to the length direction of the other side of the chute, which is perpendicular to the axis of the connecting sleeve 2, the length direction of the other side of the chute 6 is reduced from large to small, the free end of the other side of the chute is a small-length section, the other side of the chute 6 is closer to the compression beads 3 relative to the other side of the chute 6, and the end part of the small diameter end of the compression sleeve 1 is correspondingly extended with the chute 6 to form a locking part 7 in sliding fit with the chute 6. In operation, when the pressing sleeve 1 presses the upper part of the pressing bead 3, the lock part 7 slides along one side of the groove body of the sliding groove 6, and when the rear pressing bead 3 clamps the rod part of the rivet 5, the pressing sleeve 1 is rotated, so that the lock part 7 slides into the other side of the sliding groove 6, and as the free end of the other side of the groove body is a small groove deep section, the joint of the other side of the groove body and the other side of the groove body is a large groove deep section, when the lock part 7 slides into the other side of the groove body of the sliding groove 6, the pressing sleeve 1 rotates more, the distance between the end face of the lock part 7 and the groove bottom of the other side of the groove body of the sliding groove 6 is smaller until the lock part 7 is completely contacted with the groove bottom of the other side of the groove body of the sliding groove 6, and friction and fastening are generated. This prevents the compression sleeve 1 from being displaced in the axial direction while clamping the shank of the rivet 5.
In order to facilitate the whole storage and arrangement of the auxiliary connector, the outer wall of the end part of the connecting sleeve 2 close to the pressing bead 3 is provided with a limit clamp, the limit clamp comprises a fixing part 4a fixedly connected with the outer wall of the end part of the connecting sleeve 2, a connecting part 4b connected to the fixing part 4a and a clamping part 4c connected to the connecting part 4b, the outer wall of the end part of the pressing sleeve 1 close to the pressing bead 3 is outwards extended and provided with a limit part 8 in limit fit with the inner side of the clamping part 4c, and the limit part 8 can move in an area surrounded by the fixing part 4a, the connecting part 4b and the clamping part 4 c. Wherein, the fixing part 4a and the end part of the connecting sleeve 2 are preferably welded and fixed. Meanwhile, the clamping part 4c is matched with the limiting part 8, so that the end face of the limiting part 8 is always positioned at the left side of the vertical center line of the pressing bead 3 (taking the direction of fig. 2 as an example), and the pressing bead 3 can be effectively prevented from sliding out of the outer wall of the connecting sleeve 2.
In addition, the present invention also provides specific structures of the fixing portion 4a, the connecting portion 4b, and the clip portion 4c as shown in fig. 1 and 2: the fixed part 4a is an annular cover plate structure fixedly connected with the outer wall of the end part of the connecting sleeve 2, the connecting part 4b is an annular ring plate structure butted with the end part of the annular cover plate structure of the fixed part 4a, and the clamping part 4c is an annular baffle plate structure butted with the annular ring plate structure of the connecting part 4 b. Of course, the fixing portion 4a, the connecting portion 4b and the clamping portion 4c may have other structures, for example, the fixing portion 4a may be a cover plate with a hollow structure, the connecting portion 4b may be a rod-shaped structure connected with the cover plate, and the clamping portion 4c may be a claw structure. Of course, in either configuration, the stopper portion 8 may be movable within the area surrounded by the fixing portion 4a, the connecting portion 4b, and the engaging portion 4 c.
In order to prevent the bead 3 from sliding out of the inner wall of the connecting sleeve 2 in the non-working state, the diameter of the hole opening of the accommodating hole of the inner wall surface of the connecting sleeve 2 is smaller than the diameter of the bead 3. Of course, the diameter of the hole opening of the receiving hole on the inner wall surface of the connecting sleeve 2 is also sufficient to be able to clamp the bead 3 to the shank of the rivet 5 when the pressing sleeve 1 is pushed.
Preferably, the number of the pressing beads 3 is three, and the pressing beads are uniformly distributed on the same circumference of the connecting sleeve 2, and the distance between the inner wall of the large-diameter end of the pressing sleeve 1 and the outer wall of the connecting sleeve 2 is smaller than the diameter of the pressing beads 3. This also prevents the bead 3 from sliding out between the inner wall of the compression sleeve 1 and the outer wall of the connection sleeve 2.
Further, in order to avoid the rivet 5 being clamped by the pressing bead 3 in a transitional manner, an annular groove 9 coaxial with the connecting sleeve 2 is formed in the inner wall of the connecting sleeve 2 opposite to the rod part of the rivet 5, and the annular groove 9 and the inner wall of the connecting sleeve 2 form a stepped surface to be matched with the positioning stop position of the end part of the rod part of the rivet 5. That is to say the stepped surface is positioned such that the shank of the rivet 5 is exactly clamped by the bead 3.
Preferably, the number of the sliding grooves 6 is two.
In order to facilitate the insertion of the shank of the rivet 5 in the connecting sleeve 2, the end of the annular groove 9 close to the seat of the rivet 5 is provided with a conical flaring structure facilitating the insertion fit of the shank of the rivet 5.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
