Detailed Description
For a thorough understanding of the present invention, reference will be made in detail to the present invention through the following detailed description of the embodiments, taken in conjunction with the accompanying drawings. The objects, features and efficacy of the invention will be apparent to those skilled in the art from consideration of this disclosure. It is to be understood that the invention may be practiced or carried out in other embodiments and that various modifications and alterations may be made in the details of the description herein without departing from the spirit or scope of the invention. The following embodiments will further illustrate the related art of the present invention in detail, but the disclosure is not intended to limit the scope of the present invention as claimed. The description is as follows:
the first embodiment is as follows:
as shown in fig. 1 to 2, a wire joint anti-falling device 100 according to an embodiment of the present invention includes: a base 1, a rotating ring 2 and an interference member 3.
The housing 1 is provided with an insertion hole 11 defining an insertion direction L. The insertion hole 11 is for inserting the wire connector 6 in the insertion direction L. In the present embodiment, the housing 1 is divided into two parts each having a semicircular hole to be assembled to form the insertion hole 11 for easy assembly, but the present invention is not limited thereto.
As shown in fig. 3A, the rotary ring 2 is movably disposed in the insertion hole 11. The rotary ring 2 has an axial direction parallel to the insertion direction L and is rotatable as a rotary shaft in the housing 1. The rotating ring 2 has at least one guide channel D provided on an inner wall of the rotating ring 2. The guide channel D includes a straight front section D1 and an inclined rear section D2, and the straight front section D1 extends in a direction parallel to the insertion direction L and accommodates the protrusion 61 of the wire connector 6 (as shown in fig. 2). The inclined rear section D2 is communicated with the straight front section D1, and the extending direction of the inclined rear section D2 forms an angle with the inserting direction L.
Specifically, in the present embodiment, the rotating ring 2 has at least two annular walls 21 provided on the inner wall of the rotating ring 2. The two annular walls 21 are clamped to form a straight front section D1; the rotating ring 2 further has an inclined stopper 22 disposed on an inner wall of the rotating ring 2, wherein the inclined stopper 22 is connected to one of the annular walls 21 and disposed behind the straight front section D1, and an inclined surface 221 of the inclined stopper 22 forms an inclined rear section D2.
The principle and procedure of rotating the rotary ring 2 by insertion of the wire joint 6 are as follows:
as shown in fig. 5, and referring to fig. 1 and 2, when the wire joint 6 enters the insertion hole 11, the protrusion 61 is aligned with the straight front section D1 of the guide channel D to be fitted into the straight front section D1; next, as shown in fig. 6, when the protrusion 61 is to enter the inclined rear section D2, it is blocked by the inclined stopper 22, and at this time, the wire joint 6 applies a force against the inclined surface 221 of the inclined stopper 22 in the insertion direction L, and the wire joint 6 applies a vector component force to the inclined surface 221, which forces the rotary ring 2 to rotate in the screwing direction R, so that the wire joint 6 rotates the rotary ring 2 while penetrating into the inclined rear section D2. The extending direction of the inclined rear section D2 determines the screwing direction R of the rotary ring 2, and the length and angle of the inclined rear section D2 determine the rotation stroke of the rotary ring 2.
The principle and process of fixing the wire joint 6 by rotation of the rotary ring 2 are as follows:
as shown in fig. 3A and 3B, the interference member 3 includes an interference piece 32 and a backstop 31. The interference member 32 is provided protruding from the outer wall of the rotary ring 2, and the check member 31 is provided in the insertion hole 11 of the housing 1 at a distance of the rotation stroke from the interference member 32. Before the rotation of the rotating ring 2, the interference member 32 is upstream in the rotation direction R with respect to the backstop member 31. The interference member 32 passes through the backstop 31 in the forward direction when the rotating ring 2 rotates in the screwing direction R.
After the interference member 32 has passed through the backstop 31 in the forward direction (i.e., after the wire connector 6 is inserted into the insertion hole 11 and enters the inclined rear section D2), if the wire connector 6 is to be pulled out, the rotating ring 2 must be reversed to reverse the wire connector 6, otherwise the protrusion 61 of the wire connector 6 will be caught on the annular wall 21 and cannot reverse (as shown in fig. 6). However, after the interference member 32 passes through the backstop 31 in the forward direction, the backstop 31 restricts the reverse rotation of the rotary ring 2 by preventing the interference member 32 from passing through the backstop 31 in the reverse direction. Since the rotary ring 2 cannot be reversed, the wire joint 6 is fixed in the insertion hole 11,
therefore, the wire connector anti-falling device 100 of the invention can prevent the wire connector 6 from falling off due to external force, ensure the stable combination of the wire and the seat body 1, and increase the stability and safety of the system. And the anti-falling device 100 is arranged in the seat body 1, so that the overall appearance of the seat body 1 is concise and attractive. In addition, the wire connector anti-falling device 100 of the present invention is very intuitive to use, and the locking effect can be achieved by a general user simply inserting the wire connector 6 directly without operating other mechanisms.
Further, in the present embodiment, as shown in fig. 3B and 4B, the height of the bulge of the interference member 32 on the outer wall of the rotating ring 2 is gradually reduced along the rotating direction R to form a slope 321 and a stop surface 322, and the height of the bulge of the check member 31 from the inner surface of the base 1 is gradually increased along the rotating direction R to form a slope 311 and a stop surface 312. When the rotary ring 2 rotates in the screwing direction R, the slope 321 of the interference member 32 passes the slope 311 of the backstop 31 forward, and finally the abutment surface 322 of the interference member 32 abuts against the abutment surface 312 of the backstop 31 to limit the reverse rotation of the rotary ring 2. In the present embodiment, the interference member 32 and the backstop member 31 each have slope surfaces 321 and 311 for guiding. However, the present invention is not limited thereto, and the interference member 32 and the backstop member 31 may have only one slope surface and the other may be a common bump. When the interference member 32 passes the backstop member 31 (in the form of a bump) with its ramp surface 321 in the forward direction, the abutment surface 322 of the interference member 32 engages the bump to limit the inversion of the rotary ring 2; alternatively, the interference member 32 may be in the form of a bump, and the rotation of the rotary ring 2 may be restricted by the interference member 32 passing forward through the ramp surface 311 of the backstop member 31 and then the abutment surface 312 of the backstop member 31 abutting against the interference member 32. However, the present invention is not limited thereto, and the forms of the interference member 32 and the backstop member 31 may be any of a variety of conventional embodiments.
Further, in the present embodiment, as shown in fig. 3B and 4B, the wire-connector falling-off prevention device 100 further includes a release member 4 disposed on the outer surface of the base 1. When the release member 4 is triggered, the interference piece 32 is released from the original position to release the reverse rotation restriction of the rotary ring 2, so that the interference piece 32 can reversely pass through the reverse stopper 31 to reverse the rotary ring 2 to pull out the wire joint 6. Thereby, the wire connector 6 can be fixed to the base 1 and can be repeatedly inserted and removed.
Specifically, in the present embodiment, the position where the release member 4 is provided is right relative to the position where the interference piece 32 passes through the check piece 31 (as shown in fig. 4B, the release member 4 is located directly above the interference piece 32). The seat 1 is provided with a groove 13 provided on the periphery of the release member 4, so that the release member 4 (in the form of a bump) can be elastically deformed to some extent after being subjected to a force. The rotating ring 2 is also provided with grooves 23 arranged at the periphery of the interference member 32, so that the interference member 32 can be elastically deformed to a certain extent after being stressed. As shown in fig. 7, when the release member 4 receives a pressing force from top to bottom, the release member 4 presses the interference piece 32 below, and the interference piece 32 moves downward to be out of position, thereby releasing the reverse restriction (as indicated by an arrow). However, the structural design of the interference piece 32 and the release member 4 in the present embodiment is not limited to this, and the interference piece 32 may be disengaged after the release member 4 is triggered by another structure. In other embodiments, after the release member 4 is triggered, the reverse stopper 31 may be moved, so that the reverse stopper 31 and the interference member 32 no longer interfere with each other to release the reverse restriction.
Further, in the present embodiment, as shown in fig. 3C and 4C, the wire joint anti-drop device 100 further includes a rebound member 5. The resilient member 5 includes an elastic piece 51 and a stopper 52, the elastic piece 51 being disposed in the housing 1 adjacent to the insertion hole 11. The elastic member 51 can be further divided into an elastic portion 511 and a fixing base 512, wherein the elastic portion 511 is a spring or a reed, and the invention is not limited thereto. The fixing base 512 is fixedly disposed on the base body 1, one end of the elastic portion 511 is fixedly connected to the fixing base 512, and the other end of the elastic portion 511 faces the blocking portion 52. The blocking part 52 is convexly arranged on the outer wall of the rotary ring 2, and rotates along the screwing direction R on the rotary ring 2, and the blocking part 52 presses the elastic part 511 of the elastic piece 51, so that the elastic part 511 is compressed to accumulate elastic potential energy; when the release member 4 is triggered to release the reverse restriction of the rotating ring 2, the elastic portion 511 tends to release the elastic potential energy, and therefore the elastic potential energy of the elastic portion 511 is released to push the stopper 52 back to the original position, so that the rotating ring 2 rotates in the reverse direction of the screwing direction R. By means of the resilient member 5, when the release member 4 is triggered, the elastic potential energy of the elastic portion 511 can naturally withdraw the wire connector 6 from the locked state, without the need for the user to apply force to pull out.
Further, in the present embodiment, as shown in fig. 3C and 4C, the base 1 has a rotation limiting portion 12 to limit the rotation angle of the rotating ring 2. In the present embodiment, the rotation limiting portion 12 is a right-angled wall, and the blocking portion 52 is used as a member interfering with the rotation limiting portion 12, so that the blocking portion 52 can rotate within a limited range of the right angle, thereby achieving the effect of limiting the rotation angle of the rotating ring 2. However, the present invention is not limited thereto, and a member interfering with the rotation restricting portion 12 may be additionally provided on the outer surface of the rotating ring 2.
Further, in the present embodiment, the wire-joint anti-drop device 100 further includes the aforementioned wire joint 6, the wire joint 6 having the convex portion 61 shaped to match the straight front section D1, the extending direction of the convex portion 61 being parallel to the insertion direction L.
Further, in the present embodiment, the protruding portion 61 and the straight front section D1 are plural, and at least one inclined rear section D2 is connected to one of the straight front sections D1. The plurality of protrusions 61 and the straight front section D1 allow the weight of the wire joint 6 and the rotating ring to be balanced, and the user does not have to take much effort to align the protrusions 61 and the straight front section D1. The number of the inclined rear sections D2 is at least one, but may be plural (less than or equal to the number of the straight front sections D1).
The present invention has been disclosed in the foregoing by way of example, and it will be understood by those skilled in the art that the example is merely illustrative of the invention and should not be construed as limiting the scope of the invention. It should be noted that all changes and substitutions equivalent to the embodiment are intended to be included in the scope of the present invention. Accordingly, the scope of the invention is defined by the claims.
