[0034] In the prior art, please refer to Figure 1 The compression tube used for crimping is generally a conventional pipe structure. One end of the suspension string to be crimped is passed through it, and then the compression tube is pressed. Then one end of the suspension string is passed through the other end of the compression tube again, and then the compression tube is pressed to complete the crimping of the suspension string. However, there is a problem: the adjacent areas of the suspension string in the compression tube will contact each other, and friction will generate heat during operation, which may easily cause wire and strand breakage, posing certain safety hazards and a greater safety risk.
[0035] Therefore, this embodiment provides a suspension string crimping structure, which can ensure that adjacent areas of the suspension string are in a separated state, prevent adjacent areas of the suspension string located in the crimping tube from contacting each other, avoid wire and strand breakage caused by frictional heat during operation, reduce safety hazards, and at the same time reduce safety risks.
[0036] See also Figure 2-Figure 4 A suspension string crimping structure provided in this embodiment includes a tube body 1 and a suspension string, wherein a first inner cavity 11 and a second inner cavity 12 are formed inside the tube body 1. After one end of the suspension string passes through the first inner cavity 11 along one end of the length direction of the tube body 1, a partial area of the suspension string located in the first inner cavity 11 is crimped to the cavity wall of the first inner cavity 11. Furthermore, after the other end of one end of the suspension string passes through the second inner cavity 12 along the length direction of the tube body 1, another area of the suspension string located in the second inner cavity 12 is crimped to the cavity wall of the second inner cavity 12.
[0037] Through the above arrangement, the parts of the suspension string that penetrate into the interior of the tube body 1 are respectively located in the first inner cavity 11 and the second inner cavity 12, thereby ensuring that the suspension string is located in adjacent areas of the first inner cavity 11 and the second inner cavity 12 and separated, avoiding friction and heat generation in different areas of the suspension string during operation, resulting in broken wires and strands, reducing safety hazards and safety risks.
[0038] For example, see Figure 2 and Figure 3 This embodiment provides a specific structure of a tube body 1, which can separate the interior of the tube body 1 into a first inner cavity 11 and a second inner cavity 12. Specifically:
[0039] The tube body 1 is formed by winding a sheet of material. One end of the sheet in the width direction is wound counterclockwise until it abuts the top surface of the central region of the sheet, forming a first inner cavity 11. The other end of the sheet in the width direction is wound counterclockwise until it abuts the bottom surface of the central region of the sheet, forming a second inner cavity 12. By ensuring that both ends of the sheet in the width direction abut the central region after winding to form the separated first and second inner cavities 11, 12 are ensured that the suspension strings located in the first and second inner cavities 11, 12 do not touch each other during operation.
[0040] Through the above arrangement, the cross-sectional shape of the tube body 1 is S-shaped. Preferably, the cross-sectional shapes of the first inner cavity 11 and the second inner cavity 12 are the same, and the first inner cavity 11 and the second inner cavity 12 are centrally symmetrical.
[0041] More preferably, the plate is processed by a hemming machine to form the tube body 1 with an S-shaped cross-section.
[0042] Optionally, the plate is made of T2 material, that is, copper, and is made by stamping.
[0043] Through the above arrangement, the parts of the suspension string that penetrate into the interior of the tube body 1 are respectively located in the first inner cavity 11 and the second inner cavity 12, thereby ensuring that the suspension string is located in the partial areas of the first inner cavity 11 and the second inner cavity 12 without contact, avoiding friction and heat generation in different areas of the suspension string during operation, resulting in broken wires and strands, reducing safety hazards and safety risks.
[0044] For example, see Figure 4 and Figure 5 This embodiment also provides a specific structure of the tube body 1, which can separate the interior of the tube body 1 into a first inner cavity 11 and a second inner cavity 12. Specifically:
[0045] The tube body 1 is formed by winding a sheet of material. One end of the sheet in the width direction is wound clockwise until it abuts the top surface of the sheet's central region, forming a first inner cavity 11. The other end of the sheet in the width direction is wound counterclockwise until it abuts the top surface of the sheet's central region, forming a second inner cavity 12. By ensuring that both ends of the sheet in the width direction abut the central region after winding to form the separated first and second inner cavities 11, 12 are ensured that the suspension strings in the first and second inner cavities 11, 12 do not contact each other during operation.
[0046] Through the above arrangement, the cross-sectional shape of the tube body 1 is a double C-shape. Preferably, the cross-sectional shape of the first inner cavity 11 and the second inner cavity 12 are the same, and the first inner cavity 11 and the second inner cavity 12 are axially symmetrical.
[0047] More preferably, the plate is processed by a hemming machine to form the tube body 1 with an S-shaped cross-section.
[0048] Optionally, the plate is made of T2 material, that is, copper, and is made by stamping.
[0049] Through the above arrangement, the parts of the suspension string that penetrate into the interior of the tube body 1 are respectively located in the first inner cavity 11 and the second inner cavity 12, thereby ensuring that the suspension string is located in the partial areas of the first inner cavity 11 and the second inner cavity 12 without contact, avoiding friction and heat generation in different areas of the suspension string during operation, resulting in broken wires and strands, reducing safety hazards and safety risks.
[0050] For example, this embodiment provides a specific structure of a tube body 1, see Figure 6 and Figure 7 , which can realize the separation of the interior of the tube body 1 into a first inner cavity 11 and a second inner cavity 12, specifically:
[0051] The tube body 1 is made of T2 profile and adopts profile extrusion molding. The heated profile is placed in a mold. The mold is in the shape of a barrel with a sealed bottom, and two columns are spaced apart at the bottom of the barrel. The columns extend along the height direction of the mold and extrude the profile to form a tube body 1 with a first inner cavity 11 and a second inner cavity 12.
[0052] Preferably, the cross-sectional shapes of the two cylinders in the mold are both circular.
[0053] Through the above arrangement, the cross-sectional shape of the tube body 1 has two circles, so as to ensure that the suspension strings do not contact during operation.
[0054] Through the above arrangement, the parts of the suspension string that penetrate into the interior of the tube body 1 are respectively located in the first inner cavity 11 and the second inner cavity 12, thereby ensuring that the suspension string is located in the partial areas of the first inner cavity 11 and the second inner cavity 12 without contact, avoiding friction and heat generation in different areas of the suspension string during operation, resulting in broken wires and strands, reducing safety hazards and safety risks.
[0055] Preferably, this embodiment designs a fourth structure based on the third structure. For details, please refer to Figure 8 , The tube body 1 is provided with a communicating groove 13, the communicating groove 13 connects the first inner cavity 11 and the second inner cavity 12, and the communicating groove 13 extends from one end of the tube body 1 in the longitudinal direction to the other end in the longitudinal direction.
[0056] Through the above arrangement, a crimping space is reserved. When the partial area of the suspension string located in the first inner cavity 11 is crimped to the cavity wall of the first inner cavity 11 and when the partial area of the suspension string located in the second inner cavity 12 is crimped to the cavity wall of the second inner cavity 12, the connecting groove 13 is squeezed to prevent the first inner cavity 11 and the second inner cavity 12 from cracking.
[0057] This embodiment provides four tube body 1 structures, all of which can form a separated first inner cavity 11 and second inner cavity 12 inside the tube body 1. After one end of the suspension string passes through the first inner cavity 11 along one end of the length direction of the tube body 1, the partial area of the suspension string located in the first inner cavity 11 is pressed against the cavity wall of the first inner cavity 11. Furthermore, after one end of the suspension string passes through the second inner cavity 12 along the other end of the length direction of the tube body 1, the other area of the suspension string located in the second inner cavity 12 is pressed against the cavity wall of the second inner cavity 12, so that the parts of the suspension string that penetrate into the tube body 1 are respectively located in the first inner cavity 11 and the second inner cavity 12, thereby ensuring that the partial areas of the suspension string located in the first inner cavity 11 and the second inner cavity 12 are separated, avoiding friction and heat generation in different areas of the suspension string during operation, thereby reducing safety hazards and safety risks.
[0058] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
