The connecting structure is a common structure, and can connect two components. In some connecting structures, the connecting rod is sleeved with the connecting female part and is matched and connected with the to-be-connected part through elastic contraction of the connecting female part.

The inventor of the application finds through research that the traditional connection female part is generally set to be tubular, so that the traditional connection female part has certain elasticity, but only the parts close to the two ends of the cylinder part can elastically shrink to a certain extent through inward deflection, and the middle part of the traditional connection female part cannot shrink due to lack of shrink space, so that the traditional connection female part has poor connection effect in some cases.

In view of this, this application proposes a connection female, aims at solving traditional connection female and only can carry out elastic contraction in its axial direction's partial position, can't wholly carry out elastic contraction, leads to traditional connection female to connect the relatively poor problem of effect when some circumstances. The inventor of the present application devised a connection female member from the viewpoint of increasing the contraction space of the connection female member so that the connection female member can be elastically contracted at any position along the axial direction thereof.

Fig. 1 to 14 are schematic structural views of a connection female member according to the present application.

Referring to fig. 1 to 3, a connection female member 100 provided in the present application is used for connecting a first structural member 300, and the connection female member 100 includes a cylindrical body 1 and a connection portion 2. The cylindrical body 1 has a first end 11 and a second end 12 which are disposed opposite to each other in the axial direction of the cylindrical body 1, a first constricted opening 13 is formed in the first end 11 of the cylindrical body 1 so as to extend in the radial direction of the cylindrical body 1, and a second constricted opening 14 is formed in the second end 12 of the cylindrical body 1 so as to extend in the radial direction of the cylindrical body 1. And the sum of the length of the first constricted opening 13 and the length of the second constricted opening 14 is greater than or equal to the length of the cylindrical body 1 in the axial direction along the cylindrical body 1. The connecting portion 2 is disposed on the outer periphery of the cylindrical body 1, and the connecting portion 2 is configured to be connected to and engaged with the first structural member 300 when the connection female member 100 is inserted into the first structural member 300.

In the solution of the present application, the cylindrical body 1 is provided with the first constricted opening 13 and the second constricted opening 14, which makes the cylindrical body 1 have a certain constricted space in the radial direction of the cylindrical body 1. Therefore, when the connection female member 100 is inserted into the mounting hole of the first structural member 300, the cylindrical body 1 can be contracted in the radial direction of the cylindrical body 1 when being pressed by the side wall of the mounting hole. The connection female 100 can be inserted into the mounting hole by contraction of the cylinder part 1. When the connection female member 100 is inserted into the mounting hole, the connection portion 2 provided on the cylindrical body 1 is connected to the inner wall of the mounting hole, thereby connecting the cylindrical body 1 to the first structural member 300.

In the present application, the sum of the length of the first constricted opening 13 and the length of the second constricted opening 14 is greater than or equal to the length of the cylindrical portion 1 in the axial direction of the cylindrical portion 1. That is, any portion of the cylindrical body 1 in the axial direction thereof has a contraction space, and therefore the connection female member 100 can elastically contract at all portions in the axial direction thereof, thereby enabling the connection female member 100 to meet more use demands and enabling the connection effect of the connection structure 200 provided with the connection female member 100 to be better.

Referring to fig. 2, in some embodiments, the width of the first constricted opening 13 is greater than the width of the second constricted opening 14 in the circumferential direction of the barrel 1. In a specific application, the connection female member 100 needs to be inserted into the mounting hole of the first structural member 300, and the first end 11 will contact the first structural member 300 before being inserted into the mounting hole. The region near the first end 11 is thus maintained in an elastically contracted state during the insertion of the connection female member 100 into the mounting hole, and thus a region relatively near the second end 12 requires a larger contraction space.

The cylindrical portion 1 actually guarantees the shrink space of the cylindrical portion 1 by opening the first shrink opening 13 and the second shrink opening 14, so that the width of the first shrink opening 13 at the first end 11 along the circumferential direction of the cylindrical portion 1 is larger than the width of the second shrink opening 14 at the second end 12, so that the area close to the first end 11 is relatively close to the second end 12 and has a larger shrink space, so that the connecting female member 100 can meet more use requirements, and the connecting effect of the connecting structure 200 provided with the connecting female member 100 is better.

Referring to fig. 3, in some embodiments, the number of first constricting openings 13 is greater than the number of second constricting openings 14. In a specific application, the connection female member 100 needs to be inserted into the mounting hole of the first structural member 300, and the first end 11 will contact the first structural member 300 before being inserted into the mounting hole. The region near the first end 11 is thus maintained in an elastically contracted state during the insertion of the connection female member 100 into the mounting hole, and thus a region relatively near the second end 12 requires a larger contraction space.

The cylinder part 1 actually guarantees the shrink space of the cylinder part by opening the first shrink opening 13 and the second shrink opening 14, so that the number of the first shrink openings 13 at the first end 11 is larger than that of the second shrink openings 14 at the second end 12, so that the area close to the first end 11 is relatively close to the second end 12 and has larger shrink space, the connecting female part 100 can meet more use requirements, and the connecting structure 200 provided with the connecting female part 100 has better connecting effect.

In some embodiments, the first structural member 300 has a mounting hole into which the connection female member 100 is inserted, and a sidewall of the mounting hole is provided with a first tooth 310. The connection portion 2 includes a second tooth 21 provided on the outer periphery of the cylindrical body 1 and corresponding to the first tooth 310, and the connection portion 2 is connected to a side wall of the mounting hole of the first structural member 300 by means of the second tooth 21 and the first tooth 310.

When the connection female member 100 is inserted into the mounting hole, the second teeth 21 collide with the first teeth 310 to be pressed, thereby contracting the cylinder 1 in the radial direction of the cylinder 1, so that the connection female member 100 can be inserted into the mounting hole. When the connection female member 100 is mounted, the second teeth 21 are not collided with the first teeth 310, and the cylinder 1 is restored to a certain extent, so that the second teeth 21 are tightly engaged with the first teeth 310.

The connection female member 100 can be tightly coupled with the first structural member 300 by the tight engagement of the second teeth 21 and the first teeth 310. In practical application, if the first structural member 300 is lighter, the first teeth 310 and the second teeth 21 may be set to be screw teeth, so that the first structural member 300 and the connection female member 100 can be directly installed through mutual rotation, and the installation is more convenient.

Each second tooth 21 has a pointing plane 21a facing away from the first end 11 of the barrel 1. The direction of extension of the pointing plane 21a may serve as a reference for the direction of extension of the corresponding second tooth 21. Wherein in one embodiment of the present application each pointing plane 21a extends in the radial direction of the barrel 1.

Referring to fig. 6, in practical application, the first teeth 310 are generally disposed along the radial extension of the mounting hole. When each of the pointing planes 21a extends along the radial direction of the cylinder 1, the extending direction of each of the second teeth 21 is relatively close to the radial direction of the cylinder 1. At this time, the extending directions of the first teeth 310 and the second teeth 21 are substantially the same, so that the degree of collision and extrusion between the second teeth 21 and the first teeth 310 is relatively moderate when the connection female member 100 is inserted into the mounting hole of the first structural member 300. This makes it not too difficult to insert the connection female member 100 into the mounting hole, and the connection strength between the first teeth 310 and the second teeth 21 is also moderate when the first structural member 300 or the connection female member 100 is subjected to an external force, so that the connection between the connection female member 100 and the first structural member 300 can withstand a large impact.

Referring to fig. 7, in another embodiment of the present application, each of the pointing planes 21a extends obliquely toward the first end 11, and an angle a between each of the pointing planes 21a and a radial direction of the barrel 1 is 0 ° < a+.ltoreq.10°.

The orientation flat 21a of each second tooth 21 is inclined toward the first end 11, while each first tooth 310 is disposed generally along the radial extension of the mounting hole. Therefore, in the present embodiment, the connection female member 100 is less likely to collide and squeeze with the first tooth 310 when being inserted into the mounting hole of the first structural member 300, which enables the connection female member 100 to be relatively easily inserted into the mounting hole for mounting, so that the connection female member 100 is more convenient to mount. However, this also makes the strength of the connection between the first teeth 310 and the second teeth 21 relatively low when the first structural member 300 or the connection female member 100 is subjected to an external force, so that the connection between the connection female member 100 and the first structural member 300 can withstand a limited impact, and thus the angle at which each of the orientation planes 21a is inclined toward the first end 11 cannot be excessively large, which would otherwise cause unstable connection between the connection female member 100 and the first structural member 300.

In general, the angle between each of the orientation planes 21a and the radial direction of the cylindrical body 1 should be 10 ° or less. When the included angle between each pointing plane 21a and the radial direction of the cylinder body 1 is smaller than or equal to 10 degrees, the degree of collision extrusion between the second teeth 21 and the first teeth 310 is smaller, the connection female member 100 is convenient to install, the connection strength between the first teeth 310 and the second teeth 21 is not too low, and most of use requirements can be met.

Referring to fig. 8, in a further embodiment of the present application, each of the orientation flat 21a extends obliquely toward the second end 12, and an angle between each of the orientation flat 21a and a radial direction of the barrel 1 is b, wherein 0 ° < b+.ltoreq.30°.

The orientation flat 21a of each second tooth 21 is inclined toward the second end 12, while each first tooth 310 is disposed generally along the radial extension of the mounting hole. Therefore, in the present embodiment, the connection female member 100 is inserted into the mounting hole of the first structural member 300, the second teeth 21 collide with the first teeth 310 to a large extent, which makes it relatively difficult to mount the connection female member 100 in the mounting hole, and there is a certain obstruction to the mounting of the connection female member 100. But this also results in a relatively high strength of the connection between the first teeth 310 and the second teeth 21 when the first structural member 300 or the connection female member 100 is subjected to an external force, so that the connection between the connection female member 100 and the first structural member 300 can withstand a large impact. The angle at which each of the orientation flats 21a is deflected toward the second end 12 cannot be too great or otherwise render the connection female 100 too difficult or impossible to install.

In practical application, the included angle between each of the pointing planes 21a and the radial direction of the barrel 1 should be 30 degrees or less. When the included angle between each of the pointing planes 21a and the radial direction of the cylinder portion 1 is smaller than or equal to 30 °, the degree of collision and extrusion between the second teeth 21 and the first teeth 310 is not too large, the connection female member 100 can be installed, and the connection strength between the first teeth 310 and the second teeth 21 is relatively large, so that relatively more use requirements can be met.

The second tooth 21 has different emphasis in the above embodiments, so that the connection female member 100 can be adjusted and selected according to the use requirement.

Referring to fig. 6 to 8, in some embodiments, the connection part 2 includes a second tooth 21, and the second tooth 21 is configured as a screw tooth or a ring tooth.

When the connection female member 100 is inserted into the first structural member 300, the connection portion 2 is inserted into the mounting hole in the first structural member 300 and connected to the side wall of the mounting hole. In a specific application, the connection portion 2 includes a screw tooth or an annular tooth, and when the connection female member 100 is inserted into the first structural member 300, the tooth can be connected with a sidewall of the mounting hole, thereby making connection of the first structural member 300 and the connection female member 100 more stable.

Referring to fig. 9, in some embodiments, the outer diameter of the barrel 1 increases gradually from the second end 12 to the first end 11. In practice, the connection female member 100 is connected to the first structural member 300 by being inserted into the mounting hole of the first structural member 300. Therefore, when the connection female member 100 is subjected to an external force with the first structural member 300, the connection female member 100 may be pulled out from the mounting hole. In the present embodiment, the outer diameter of the barrel 1 gradually increases from the second end 12 to the first end 11, so that the barrel 1 is pulled out from the mounting hole to receive a larger resistance, so that the connection between the connection female member 100 and the first structural member 300 is more stable.

In some embodiments, the barrel 1 is configured as a bellows spring 3. According to the characteristics of the ripple spring 3 itself, the ripple spring 3 is elastically contracted when being pressed in the radial direction of the ripple spring 3, so that the ripple spring 3 can be smoothly installed into the installation hole. The structure of the ripple spring 3 is mature, and the barrel 1 can solve the development cost and reduce the production difficulty through being constructed into the ripple spring 3.

Referring to fig. 10 to 11, in an embodiment of the present application, the crests 31 and the troughs 32 of the corrugated spring 3 are alternately connected in a ring-like structure along the circumferential direction of the mounting hole. The wave springs 3 are more in style, such as transverse wave springs 3 and longitudinal wave springs 3. The crests 31 and the troughs 32 of the transverse corrugated springs 3 are alternately connected in a ring-shaped structure along the circumferential direction of the mounting hole, and when the transverse corrugated springs 3 are inserted into the first structural member 300, the crests 31 contract and expand, so that the transverse corrugated springs 3 can be extruded into the mounting hole of the first structural member 300, and the mounting is completed.

In another embodiment of the present application, the crests 31 and the troughs 32 of the corrugated spring 3 are alternately connected in a ring-like structure in the axial direction of the mounting hole. The ripple spring 3 is configured as a longitudinal ripple spring 3, and crests 31 and troughs 32 of the longitudinal ripple spring 3 are alternately connected in a ring-like structure in the axial direction of the mounting hole. When the longitudinal wave spring 3 is inserted into the first structural member, the wave crests 31 contract and expand, so that the longitudinal wave spring 3 can be extruded into the mounting hole of the first structural member 300 to complete the mounting.

Referring to fig. 12, in some embodiments, the wall thickness of the barrel 1 gradually decreases from the second end 12 to the first end 11. In a specific application, the first end 11 of the barrel 1 contacts the first structural member 300 earlier than the second end 12, and the first end 11 of the barrel 1 is inserted from the mounting hole, and the number of times and time of elastic contraction of the area of the barrel 1 near the first end 11 are relatively longer during the process of inserting the barrel 1 into the mounting hole. In this embodiment, therefore, the wall thickness of the barrel 1 tapers from the second end 12 to the first end 11, i.e., the wall thickness of the first end 11 is thinner than the wall thickness of the second end 12. This makes the elastic contractibility of the first end 11 of the barrel 1 better, and facilitates the installation of the barrel 1.

Referring to fig. 13, in some embodiments, the barrel 1 includes a first portion 15 and a second portion 16 connected in sequence, and the connecting portion 2 includes a thread tooth provided on the first portion 15 and an annular tooth provided on the second portion 16. The thread teeth are used for being in threaded connection with the second structural member 400, and the annular teeth are used for being in connection fit with the first structural member 300.

In this embodiment, the screw thread teeth may be screwed with the second structural member 400, the ring-shaped teeth may be in connection with the first structural member 300, so that the first portion 15 may be screwed with the second structural member 400, and the second portion 16 may be connected with the first structural member 300. That is, the cylindrical body 1 is screw-coupled with the second structural member 400 through the first portion 15 and coupled with the first structural member 300 through the second portion 16, so that the first structural member 300 is coupled with the second structural member 400 in opposition. Thus, in this embodiment, the connection female member 100 itself is able to connect the first structural member 300 with the second structural member 400 without resorting to other structures.

Referring to fig. 13, in some embodiments, the barrel 1 includes a first portion 15 and a second portion 16 connected in sequence, the connecting portion 2 includes annular teeth respectively disposed on the first portion 15 and the second portion 16, the first portion is configured to be connected to the second structural member 400, and the second portion 16 is configured to be connected to the first structural member 300.

In the present embodiment, the cylindrical body 1 includes the first portion 15 and the second portion 16, so as to be connected to the first structural member 300 and the second structural member 400 through the first portion 15 and the second portion 16, respectively. This eliminates the need for the connector rail 210 in the connection structure 200 to connect the first structural member 300 with the second structural member 400 by the connector female member 100. In this case, there are many embodiments of the connection portion 2, for example, the connection portion 2 includes annular teeth provided on the first portion 15 and the second portion 15 in this embodiment, so as to be connected to the first structural member 300 and the second structural member 400, respectively.

In some embodiments, the barrel 1 includes a first portion 15 and a second portion 16 connected in sequence, the connecting portion 2 includes thread teeth respectively disposed on the first portion 15 and the second portion 16, the first portion 15 is configured to connect with the second structural member 400, and the second portion 16 is configured to connect with the first structural member 300.

In the present embodiment, the cylindrical body 1 includes the first portion 15 and the second portion 16, so as to be connected to the first structural member 300 and the second structural member 400 through the first portion 15 and the second portion 16, respectively.
