Description

Technical Field

[0001] The present application relates to the field of traction ropes, and in particular to a connection structure and a traction rope having the connection structure. Background Art

[0002] The existing traction ropes usually include a traction rope body and a sleeve sleeved on the outside of the traction rope body. The current sleeves include spring sleeves and PVC sleeves, which have good wear resistance, protection and strength.

[0003] However, the above scheme also has certain disadvantages. Since the traction rope needs to be laid out according to the design plan of the frame during installation and use, it needs to be bent. The current practice is to fix it on the frame through a clip, and the traction rope is positioned by the clip. Since both spring sleeves and PVC sleeves are currently used, due to their hard material, they are difficult to bend during layout and inconvenient to install. After the layout, the friction between the traction rope and the inner wall of the tube is large, the traction rope is severely worn, and even breaks. Therefore, technical personnel in this field need to develop a traction rope with a flexible sleeve.

[0004] It was discovered during use that the flexible sleeve also has certain disadvantages, namely, the structural design of its connecting end is currently fixed directly by a buckle, but after the connecting end of the flexible sleeve is fixed, since the flexible sleeve is relatively soft, twisting and deformation will occur between the connecting end and the flexible sleeve, increasing the friction between the traction rope.

[0005] In view of this, those skilled in the art need to improve the existing traction rope to overcome the above-mentioned defects. Utility Model Content

[0006] The main purpose of the present application is to provide a connection structure and a traction rope having the connection structure, which solves the problem that the connection of the flexible sleeve is twisted and deformed when the traction rope with the flexible sleeve is connected.

[0007] In order to achieve the above-mentioned objectives, in the first aspect, the present application provides a connection structure including an inner lining member made of metal and an outer sleeve member matching the inner lining member, the inner lining member and the outer sleeve member being fixed by snap fit, a gap being formed between the inner lining member and the outer sleeve member to clamp the end of the flexible sleeve, and the inner lining member being provided with an opening for the traction rope to pass through.

[0008] A further improvement is that a plurality of elastic support spring sheets are arranged on the inner side of the lining member, and the plurality of elastic support spring sheets are evenly distributed on the circumference of the lining member.

[0009] A further improvement is that a mesh structure is provided on the outer circumference of the lining member and / or the inner circumference of the outer sleeve member.

[0010] A further improvement is that the inner lining is made of zinc alloy, and the outer casing is made of aluminum alloy.

[0011] A further improvement is that the thickness of the elastic supporting spring is half of the wall thickness of the flexible sleeve.

[0012] In order to achieve the above-mentioned purpose, in a second aspect, the present application provides a traction rope, including a flexible sleeve assembly, a traction rope body inserted into the flexible sleeve assembly, the flexible sleeve assembly includes a flexible tube body, the above-mentioned connecting structure fixedly arranged at both ends of the flexible tube body, and a plurality of spherical support members arranged in the flexible tube body, each of the spherical support members is provided with a through hole for the traction rope body to pass through.

[0013] A further improvement is that the flexible pipe body is made of polyethylene material.

[0014] A further improvement is that trumpet-shaped expansion grooves are provided at both ends of the perforation on the spherical support member.

[0015] The utility model provides a connection structure and a traction rope with the connection structure. Compared with the prior art, the beneficial effect is that by improving the connection structure, it includes an inner lining member and an outer sleeve member. When connected, the inner lining member is inserted into the flexible sleeve to play a supporting role, and the outer sleeve member clamps the flexible sleeve and fixes it with the inner lining member, and the elastic supporting spring sheet on the inner lining member supports the flexible sleeve close to the inner lining member, thereby avoiding the increase of friction between the traction rope and the flexible sleeve.

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] like Figure 1As shown, a connection structure includes an inner lining member 1 made of metal and an outer sleeve member 2 matched with the inner lining member 1, the inner lining member 1 and the outer sleeve member 2 are fixed by being snapped together, and a gap is formed between the inner lining member 1 and the outer sleeve member 2 to clamp the end of the flexible sleeve, and the inner lining member 1 is provided with an opening for the traction rope to pass through. When connected with the flexible sleeve, the inner lining member 1 is inserted into the flexible sleeve to play a supporting role, and the traction rope directly passes through the perforation on the inner lining member 1 to avoid connection with the flexible sleeve. In addition, the outer sleeve member 2 clamps the flexible sleeve and is snapped together with the inner lining member 1 to fix it. Preferably, a plurality of elastic support springs 3 are provided on the inner side of the inner lining member 1, and the plurality of elastic support springs 3 are evenly distributed on the circumference of the inner lining member 1. The elastic support springs 3 support the flexible sleeve close to the inner lining member 1, thereby further avoiding an increase in friction between the traction rope and the flexible sleeve.

[0027] In order to make the connection between the lining member 1 and the outer sleeve 2 tighter, the outer circumference of the lining member 1 and / or the inner circumference of the outer sleeve 2 is provided with a mesh structure, and the mesh structure can be sawtooth, wavy or other shapes.

[0028] Preferably, the inner lining 1 is made of zinc alloy, and the outer casing 2 is made of aluminum alloy. Since aluminum alloy has better plasticity than zinc alloy, it is arranged on the outside to facilitate its deformation when buckled, while the inner lining 1 is harder and has a better supporting effect.

[0029] In order to support the wall of the flexible sleeve and avoid interference with the traction rope, the thickness of the elastic support spring sheet 3 is half of the wall thickness of the flexible sleeve.

[0030] like Figure 2 As shown, a traction rope comprises a flexible sleeve assembly, a traction rope body 6 inserted into the flexible sleeve assembly, the flexible sleeve assembly comprises a flexible tube body 4, the above-mentioned connection structure fixedly arranged at both ends of the flexible tube body 4, and a plurality of spherical support members 5 arranged in the flexible tube body 4, each of the spherical support members 5 is provided with a through hole for the traction rope body 6 to pass through, and the flexible tube body 4 is made of polyethylene material.

[0031] The invention comprises a sleeve made of softer polyethylene material instead of the original PVC material, so that the sleeve has better flexibility and is more convenient to bend during layout planning. In addition, a plurality of spherical supports 5 are provided, which not only serves the purpose of supporting the sleeve, but also allows the traction rope to directly pass through the perforations on the spherical supports 5 to avoid contact with the inner wall of the sleeve. Moreover, when bending, part of the spherical supports 5 is gathered at the bending point, which not only improves the strength, but also avoids increase in friction between the traction rope and the inner wall of the sleeve at the bending point, thereby avoiding excessive wear of the traction rope.

[0032] In order to reduce the friction between the traction rope and the end of the hole on the spherical support member 5, trumpet-shaped expansion grooves are provided at both ends of the hole on the spherical support member 5.

[0033] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
