[0027] The invention will now be further described with reference to the accompanying drawings.

[0028] In order to make the technical solutions, technical objectives and technical effects of the present invention clearer, and enable those skilled in the art to understand and implement the present invention, a more detailed description of the present invention is presented hereinafter with reference to the accompanying drawings and specific embodiments.

[0029] As shown in Figs. 1 to 7, Fig. 1 is a schematic structural diagram of a rope fastener according to a preferred embodiment of the present invention. Fig. 2 is a schematic exploded view of the rope fastener shown in Fig. 1. Fig. 3 is another schematic exploded view of the rope fastener shown in Fig. 1. Fig. 4 is a schematic structural diagram of a base body of the rope fastener shown in Fig. 1. Fig. 5 is a schematic structural diagram of a fastening member of the rope fastener shown in Fig. 1. Fig. 6 is a diagram for explaining a usage state of the rope fastener shown in Fig. 1. Fig. 7 is a diagram for explaining another usage state of the rope fastener shown in Fig. 1. The rope fastener includes a base body 100 and a fastening member 200 .

[0030] A slide channel 160 is formed in the base body 100, and the slide channel 160 has a first opening 161. A pair of side walls 120 located on either side of the slide channel 160 of the base body 100 gradually approach each other toward the first opening 161.

[0031] The support portion 140 is formed in the slide channel 160 of the base body 100. The fastening member 200 is slidably disposed in the slide channel 160.

[0032] The rope fastener is disposed in the slide channel 160, between the support portion 140 and the fastening member 200, and further includes a spring 300 supported by the support portion 140, the elastic force of which causes the fastening member 200 to apply force to the pair of side walls 120, fastening the rope 400 located between the fastening member 200 and the side wall 120.

[0033] The above technical solution is a basic solution. When the spring 300 is compressed, the fastening member 200 slides away from the first opening 161 and forms a gap with the pair of side walls 120, respectively. At this time, the rope 400 can slide. When the spring 300 begins to expand, the fastening member 200 approaches the pair of side walls 120, respectively, thereby exerting a force on the pair of side walls 120 to fasten the rope 400 located between the fastening member 200 and the side walls 120, thereby achieving the basic function of the rope fastener. In this embodiment, the base body 100 is in the shape of a bag mouth.

[0034] Furthermore, in this embodiment, as shown in FIGS. 4, 6 and 7, the base body 100 further includes a bottom 110, and the pair of side walls 120 are disposed on the pair of sides of the bottom 110, respectively.

[0035] The base body 100 further includes an upper portion 130 disposed opposite the bottom portion 110 at a distance therefrom and connected to each of the pair of side walls 120. The support portion 140 is located between the pair of side walls 120 and connected to each of the bottom portion 110 and the upper portion 130.

[0036] The slide channel 160 is surrounded by the bottom 110, the top 130, the support 140, and the pair of side walls 120. The first opening 161 is surrounded by the bottom 110, the top 130, and the pair of side walls 120. The slide channel 160 is further provided with a second opening 162 and a third opening 163. The second opening 162 is surrounded by the bottom 110, the top 130, and one of the side walls 120. The third opening 163 is surrounded by the bottom 110, the top 130, and the other side wall 120.

[0037] The slide channel 160 is used to pass two ropes 400, one rope 400 passing through the first opening 161 and the second opening 162 respectively, and the other rope 400 passing through the first opening 161 and the third opening 163 respectively.

[0038] Here, as the pair of side walls 120 move closer to each other toward the first opening 161, the interior of the slide channel 160 narrows toward the first opening 161. Here, top, bottom, and sides do not indicate any limitations to structural features, but are merely for convenience in describing the positional relationships between various structures, and do not serve as a limitation to the scope of the present application.

[0039] 2 and 5, the fastening member 200 includes a base portion 210 and a pair of fastening portions 220 each formed on a bottom portion of the base portion 210. The pair of fastening portions 220 are arranged opposite each other and, together with the base portion 210, surround an accommodating groove 250 for accommodating the spring 300. The fastening member 200 further includes a blocking portion 230 formed on the base portion 210 and disposed in the accommodating groove 250 for the spring 300 to apply a force.

[0040] Here, the receiving groove 250 prevents the spring 300 from sliding out of the slide channel 160. Meanwhile, the fastening portion 220 has a one-to-one correspondence with the side wall 120. Under the action of the elastic force of the spring itself, the fastening portion 220 and the corresponding side wall 120 can fasten the rope 400 therebetween.

[0041] 2, 6, and 7, in this embodiment, the fastening portion 220 has engagement teeth 221. The use of the engagement teeth 221 can increase the friction between the fastening portion 220 and the rope 400 when the fastening portion 220 is in contact with the rope 400.

[0042] Further, a linear notch 131 is formed in the upper portion 130 , and the base portion 210 is slidably disposed in the linear notch 131 .

[0043] A push cover 240 is further formed on the top of the base portion 210 .

[0044] Now, by manipulating the push cover 240 , the fastener 200 can be actuated to slide within the slide channel 160 .

[0045] Furthermore, in this embodiment, as shown in FIG. 2, the base body 100 further includes a linear clamp portion 150 formed on the bottom portion 110 and disposed in the slide channel 160 .

[0046] The extending direction of the clamp portion 150 coincides with the extending direction of the linear cutout 131 .

[0047] The fastening member 200 is fitted into the clamp portion 150 via an accommodating groove 250 so as to be slidably disposed in the clamp portion 150. The blocking portion 230 is in contact with the clamp portion 150.

[0048] Here, the sliding stroke of the fastening member 200 on the base body 100 can be determined by the engagement between the accommodating groove 250 and the clamp portion 150, and based on the base portion 210 slidably arranged in the linear notch 131.

[0049] Further, as shown in Figures 2 and 6, a pair of slide rails 132 are formed on the wall surface of the upper portion 130 located outside the slide channel 160, and the pair of slide rails 132 are respectively disposed on a pair of sides of the linear notch 131.

[0050] A pair of slide grooves 241 are formed on the bottom surface of the push cover 240. The pair of slide grooves 241 are formed on a pair of side portions of the base portion 210, respectively. The slide grooves 241 correspond one-to-one to the slide rails 132, and the slide rails 132 are disposed in the slide grooves 241 so as to be relatively slidable.

[0051] Here, the fit between the slide groove 241 and the slide rail 132 further ensures the stability of the linear sliding of the fastening member 200.

[0052] 2, a pair of tenon protrusions 133 are further formed on the wall surface of the upper portion 130 located outside the slide channel 160. The pair of tenon protrusions 133 are respectively disposed on the pair of sides of the linear notch 131.

[0053] The push cover 240 is provided with a pair of fastening portions 242. The pair of fastening portions 242 are respectively disposed on a pair of sides of the base portion 210. The fastening portions 242 correspond one-to-one with the tenon protrusions 133, and the tenon protrusions 133 are detachably fastened to the corresponding fastening portions 242. In this embodiment, the fastening portions 242 are slide grooves.

[0054] Here, when the fastening portion 242 fits over the tenon projection 133 and is fixed, the entire rope fastener is fixed to the rope 400 connected thereto.

[0055] In the case of the rope fastener of the present application, due to the first opening, the pair of ends of the stroke of the slide channel are not completely closed, and the slide stroke of the fastening member in the base body is increased, thereby providing a relatively large space to accommodate various ropes, and further simplifying the assembly of the rope fastener of the present application. At the same time, the rope fastener of the present application adopts the engagement of the fastening portion and the tenon protrusion outside the slide channel, which does not occupy any space in the slide channel. In addition, the rope fastener of the present application also improves the pulling resistance through the bag-mouth-type base body, thereby successfully compensating for the reduction in strength caused by the formation of the first opening and enhancing the stability of the entire rope fastener.

[0056] Although the embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above specific embodiments. The above specific embodiments are for illustrative purposes and are not limiting.
