Detailed Description

The core of the utility model is to provide the side pressure same-mould rope buckle, which is provided with only one outer piece and two inner pieces, and is provided with three parts, so that the assembly can be realized more conveniently without the help of other auxiliary accessories such as springs.

In order to make the technical scheme of the present utility model better understood by those skilled in the art, the following detailed description will be made on the side pressure common mode rope fastener of the present utility model with reference to the accompanying drawings and the specific embodiments.

The utility model provides a side pressure same-mode rope fastener, which is shown in fig. 2 and 3, and comprises an outer piece 1 and two inner pieces 2, and is shown in fig. 6, wherein an X axis represents a first direction, a Y axis surface is in a second direction, the outer piece 1 is provided with two groups of outer rope penetrating holes 11 along the first direction, as the outer piece 1 is of a shell structure with hollowed inside, the side walls of the two ends of the outer piece 1 along the first direction are provided with through holes, the outer rope penetrating holes 11 of the same group are arranged in a collinear and through way, and one group of outer rope penetrating holes 11 can penetrate a section of rope. In the embodiment shown in the drawings of the present utility model, the set of outer reeving holes 11 comprises two collinear through holes.

The two inner parts 2 have the same appearance, so that only one set of die is needed to be arranged when the inner parts 2 are manufactured, and the die opening cost can be reduced. Each inner part 2 comprises a base 21 and an elastic strip 22, which are integrally formed, and the inner parts 2 can be plastic parts which are integrally formed by injection molding.

The directional description with respect to the inner member 2 refers to a state when the inner member 2 and the outer member 1 are assembled with each other; each base 21 is provided with a set of inner reeving holes 211 in a first direction, through which a rope can pass through the set of inner reeving holes 211 and the set of outer reeving holes 11; in the embodiment shown in the drawings, the inner rope threading holes 211 are a channel with two ends penetrating, but the utility model does not exclude other arrangements, such as two channels.

Referring to fig. 5, a set of inner rope holes 211 and a set of outer rope holes 11 can be penetrated by one rope, and in general, only one rope needs to be penetrated in one passage formed by a set of inner rope holes 211 and a set of outer rope holes 11, but the present utility model does not exclude the case of simultaneously penetrating two ropes side by side. It should be noted that the ropes passing through the two channels may be different portions of the same rope, but the utility model will be referred to herein as a rope passing through a channel for convenience of description. The inner diameters of the inner and outer rope penetration holes 211 and 11 are larger than the outer diameter of the rope, and the rope can be allowed to freely move therein when the inner and outer rope penetration holes 211 and 11 are directly penetrated.

The outer member 1 is provided with a button channel 12 in a second direction, the first direction being perpendicular to the second direction. The inner member 2 is slidably inserted into the button channel 12, and the inner member 2 is movable along the length of the button channel 12. Referring to fig. 4 and 5, fig. 4 shows a state in which the inner rope passing hole 211 and the outer rope passing hole 11 are offset from each other to lock the rope, and fig. 5 shows a state in which the inner rope passing hole 211 and the outer rope passing hole 11 are opposite to each other to unlock the rope.

The two inner parts 2 are distributed in a central symmetry manner, so that the elastic strip 22 of one inner part 2 is propped against the base 21 of the other inner part 2; the left end of the elastic strip 22 provided on the right base 21 is abutted against the left base 21, and the right end of the elastic strip 22 provided on the left base 21 is abutted against the right base 21. The elastic strip 22 is capable of generating an elastic force in the second direction, so that the two bases 21 have a tendency to separate from each other. When the inner member 2 is in the locked state, a part of the two bases 21 protrudes outside the outer member 1, and can be pressed by the hand.

When in use, the ropes sequentially pass through the outer rope threading holes 11 and the inner rope threading holes 211, the ropes are dislocated by the elastic force of the elastic strips 22, the position locking of the ropes is realized at the moment, and the ropes cannot move at the moment; when the two bases 21 are pressed against each other, the two bases 21 are brought close to each other, and the penetration directions of the outer rope penetration hole 11 and the inner rope penetration hole 211 are aligned to thereby achieve unlocking, at which time the rope can move the adjustment position.

The side pressure common-mode rope fastener provided by the utility model is only provided with the outer piece 1 and the two inner pieces 2, the two inner pieces 2 adopt the same structural design, other auxiliary accessories such as springs and the like are not needed, and only the two inner pieces 2 are needed to be inserted relatively from the openings at the two ends of the button channel 12 during assembly, so that the assembly can be realized more conveniently.

On the basis of the scheme, the side walls of the base 21 are symmetrically provided with the limit lugs 212, the limit lugs 212 protrude out of the two side walls of the base 21, and the two limit lugs 212 are arranged in a protruding mode along the first direction; in connection with fig. 4, the limit bump 212 can be in contact with the inner surface of the outer member 1, thereby defining the maximum spacing of the bases 21. The two elastic strips 22 generate elastic force for separating the bases 21 from each other, and if the positions of the bases 21 are not limited, the two bases 21 are separated from the outer member 1, so that the maximum separation distance of the two bases 21 needs to be limited by the limiting bump 212.

As shown in fig. 3 and 4, the edge of the button channel 12 of the outer member 1 is provided with a mounting groove 121 for guiding the limit bump 212, and the mounting groove 121 is arranged at the edge of the button channel 12, which is equivalent to arranging a notch at the edge of the button channel 12 to form an inclined slope. The spacing lug 212 is also provided with an inclined slope, the slope of the mounting groove 121 and the slope of the spacing lug 212 are parallel to each other, and the distance between the two spacing lugs 212 (the first direction) is greater than the width of the button channel 12 (the first direction), so that after the two spacing lugs 212 are clamped into the outer piece 1, the two spacing lugs are difficult to reversely move out again, and the spacing effect is achieved.

Referring to fig. 2, the limiting bump 212 is disposed at a middle position of two opposite short sides of the base 21, where two opposite short sides of the base 21 are respectively provided with a limiting bump 212, and the two short sides of the base 21 are relatively flat, and the corners of the long sides and the short sides of the base 21 are smoothly transition rounded corners, so that the base is not easy to be disposed. The present utility model does not exclude the configuration of two or more limit projections 212, and these embodiments are included in the scope of the present utility model.

Referring to fig. 2, a positioning groove 213 is formed on the base 21, the positioning groove 213 is in a groove structure, the positioning groove 213 is used for accommodating and positioning the elastic strip 22 of another internal component 2, the elastic strip 22 extends into the positioning groove 213 along the second direction, the positioning groove 213 defines the positions of the end portion of the elastic strip 22 in the X-axis and Z-axis directions, and the positioning groove has a limiting function to prevent the elastic strip 22 from being misplaced.

Specifically, the elastic strip 22 provided by the utility model is arranged in a wave-shaped reciprocating bending way, and elastic force is generated through the bending part; the portion of the end of the elastic strip 22 contacting the positioning groove 213 is planar to ensure the stability of positioning.

Referring to fig. 2, the two elastic strips 22 are formed so as to avoid each other in the longitudinal direction of the base 21; as shown in fig. 7, the two elastic strips 22 are retracted from each other in the width direction of the base 21. Fig. 2 and 7 show two different embodiments, the structure of the outer piece 1 and the base 21 being substantially identical, the main difference being the difference in the elastic strips 22. The base 21 has a length direction of X axis and a width direction of Z axis, and in the embodiment shown in fig. 2, the two elastic strips 22 are offset from each other in the X axis direction; in the embodiment shown in fig. 7, the two elastic strips 22 are offset from each other in the Z-axis direction. The same effect can be achieved in both embodiments, only with differences in the arrangement of the elastic strips 22, which are within the scope of the utility model.

Referring to fig. 3 and 7, an arc-shaped concave button surface 214 is provided on the outer surface of the base 21, and an anti-slip strip 215 for increasing friction force is provided on the button surface 214. The button surface 214 is arranged on the surface of the base 21 for hand contact pressing, and the middle of the button surface 214 is concave and matched with the shape of the finger, so that the comfort of pressing the finger is improved. The anti-slip strip 215 has a convex block structure protruding from the button surface 214, so that the friction force with fingers can be increased, and slipping can be prevented.

Specifically, the outer member 1 provided by the utility model has a flat cylindrical shape, the axis direction of the outer member 1 is along the first direction, the cylindrical axis is along the X-axis direction, and the height of the Z-axis direction is minimum.

In connection with fig. 4, in the locked state, the outer and inner lacing holes 11, 211 are exactly completely staggered, and for the left half, the right side edge of the inner lacing hole 211 coincides with the left side edge of said outer lacing hole 11. It should be noted that fig. 4 shows a state without threading, and if the rope is threaded, the base 21 is difficult to extend to reach such a state because the rope forms a certain obstruction, and the extending length is slightly shorter.

With reference to fig. 5, in the unlocked condition, the seat 21 is fully entered into the outer piece 1, at which time, for the left half, the left edge of the seat 21 is now flush with the left edge of the outer piece 1; the finger will contact the edge of the outer member 1 after pressing to this position, which can give the effect of tactile positioning.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present utility model. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model. Thus, the present utility model is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
