Description

Technical Field

[0001] The present application relates to the technical field of braided belt connection, and in particular to a braided belt connection structure. Background Art

[0002] In the fire hose made of polyester thread, the related technology generally uses iron wire, clamps, etc. to directly press the braided belt onto the fire hose connector. This method has the following problems:

[0003] 1) Insufficient connection strength;

[0004] 2) Iron wire and clamps will damage the polyester thread and the belt body;

[0005] 3) There are protruding metal parts on the outside of the braided belt, which may cause damage to the operator;

[0006] 4) When the male and female connectors are pulled at high speed (speed greater than 30m / s), the protruding metal parts may get caught on the unmoved braided belt, causing the entire unmoved braided belt to fly out. Utility Model Content

[0007] The present application aims to provide a braided belt connection structure with high connection strength, no damage to the braided belt, and not easy to fall off, and adopts the following technical solutions:

[0008] A braided belt connection structure, comprising:

[0009] braided belt;

[0010] A connecting piece, the connecting piece comprising a connecting section and a tapered section, the tapered section comprising a large hole end and a small hole end; and

[0011] An inner cone sleeve, the inner cone sleeve comprising a large head end and a small head end, the outer diameter of the large head end being smaller than the inner diameter of the large hole end and larger than the inner diameter of the small hole end, and the inner diameter of the small head end being smaller than the inner diameter of the small hole end;

[0012] The inner cone sleeve is inserted into the braided belt from the small head end, and the end of the braided belt is folded back into the inner cone sleeve from the large head end and passes through the small head end; and the inner cone sleeve with the braided belt is inserted into the conical section of the connecting piece.

[0013] Furthermore, the end of the braided belt passes through the small end of the inner cone sleeve by no less than 20 mm.

[0014] Furthermore, a sleeve is sleeved inside the folded portion of the braided belt; the braided belt and the sleeve are sewn together at the folded portion of the braided belt by sewing thread.

[0015] Furthermore, the taper of the small head end of the inner cone sleeve is greater than the overall taper of the inner cone sleeve.

[0016] Furthermore, a groove is provided on the inner wall of the tapered section of the connecting piece.

[0017] Furthermore, the inner taper of the tapered section of the connecting piece is smaller than the outer taper thereof.

[0018] Furthermore, the inner taper of the tapered section of the connecting piece is 5°±0.5°.

[0019] Furthermore, the small hole end of the connecting piece is rounded.

[0020] Beneficial effects of this application:

[0021] The braided belt and the connecting parts in this application have no protruding metal parts on the outside, which is not easy to cause damage to the operator during operation. At the same time, the belt body will not be damaged when it moves at high speed, nor will it get caught on other belt bodies; the overall connection strength of this application can reach 60% of the belt body strength, which is suitable for working conditions with relatively strict requirements on belt body strength; in the pre-tightening stage, this application can achieve consistent pre-tightening degree, with high reliability, and avoid the use of clamps and the like that cause inconsistent pre-tightening force.

[0034] Reference Figure 1-3 , the present application provides a braided belt connection structure, comprising:

[0035] Braided belt 300;

[0036] A connector 100 comprising a connecting section 130 and a tapered section 140 , wherein the tapered section 140 comprises a large hole end 141 and a small hole end 142 ; and

[0037] An inner cone sleeve 200 includes a large head end 210 and a small head end 220 . The outer diameter of the large head end 210 is smaller than the inner diameter of the large hole end 141 and larger than the inner diameter of the small hole end 142 . The inner diameter of the small head end 220 is smaller than the inner diameter of the small hole end 142 .

[0038] The inner cone sleeve 200 is inserted into the braid 300 by its small head end 220, and the braid 300 is folded back into the inner cone sleeve 200 by the large head end 210 and passes through the small head end 220; and the inner cone sleeve 200 with the braid 300 is inserted into the conical section 140 of the connecting piece 100.

[0039] Specifically, refer to Figure 2 The connector 100 includes a male connector 110 and a female connector 120. The male connector 110 can be inserted into the female connector 120 to achieve end-to-end connection. In addition, the male connector 110 and the female connector 120 can also be connected to matching connectors provided on other facilities.

[0040] Refer again Figure 1 and 2 The male connector 110 and the female connector 120 are respectively placed on the outside of the braided belt 300, with the connecting sections 130 of the male connector 110 and the female connector 120 facing away from each other. After the male connector 110 and the female connector 120 are placed, the inner cone sleeve 200 is respectively inserted into the ends of the braided belt 300, with the inner cone sleeve 200 inserted from its small end 220. After the inner cone sleeve 200 is completely inserted into the braided belt 300, the end of the braided belt 300 is bent so that the end of the braided belt 300 passes through the inner cone sleeve 200 from the large end 210 of the inner cone sleeve 200 and exits from the small end 220 of the inner cone sleeve 200; the braided belt 300 and the connector 100 are pulled so that the inner cone sleeve 200 with the braided belt 300 slides into the tapered section 140 of the connector 100; finally, the inner cone sleeve 200 is pressed tightly with a tool so that the braided belt 300 and the inner wall of the tapered section 140 of the connector 100 have a certain fitting length.

[0041] Reference Figure 1 It can be understood that the end of the braided belt 300 passes through the small end 220 of the inner cone sleeve 200 by no less than 20 mm.

[0042] Specifically, in order to prevent the braided belt 300 from falling off, the end of the braided belt 300 needs to extend beyond the small end 220 of the inner cone sleeve 200. At the same time, in order to prevent the extended braided belt 300 from affecting material transportation, the extended length should not be too long.

[0043] Reference Figure 1 It is understandable that a loop may be provided inside the folded portion of the braided belt 300 , and the braided belt 300 and the loop may be sewn together at the folded portion of the braided belt 300 by sewing thread.

[0044] Specifically, the collar can be a steel ring with an outer diameter equal to that of the large end 210 of the inner cone sleeve 200. The collar is sewn together with the braid 300 using sewing thread made of the same material. The sewing thread is wrapped around the steel ring, with a stitch density of 2-4 mm / stitch. The collar serves as a support during sewing, ensuring a secure fit for the braid 300. Furthermore, when the braid 300 is subjected to stress, it is held in place by the inner cone sleeve 200 while being secured to the collar, preventing it from slipping.

[0045] Reference Figure 1 and 3 It can be understood that the taper of the small head end 220 of the inner cone sleeve 200 is greater than the overall taper of the inner cone sleeve 200 .

[0046] Specifically, since the braided belt 300 is a flexible part as a whole and the connector 100 is a rigid part, by setting the small head end 220 of the inner cone sleeve 200 to have a larger taper, the turning radius of the braided belt 300 can be increased and the shear strength can be reduced when the movement directions of the braided belt 300 and the connector 100 are inconsistent.

[0047] Reference Figure 1 and 2 It can be understood that a groove is provided on the inner wall of the tapered section 140 of the connecting member 100 .

[0048] Specifically, by providing grooves on the inner wall of the tapered section 140, the friction between the braided belt 300 and the inner wall of the tapered section 140 can be increased, thereby enhancing the connection strength. The grooves can be arranged along the circumference of the tapered section 140, with a spacing of 4mm-5mm between the grooves and a groove depth of 0.1mm-0.4mm. After grooving, burrs are removed.

[0049] Reference Figure 2 It can be understood that the inner taper of the tapered section 140 of the connecting member 100 is smaller than the outer taper thereof.

[0050] Specifically, the different inner and outer tapers of the connecting member 100 can increase the thickness of the small hole end 142 of the connecting member 100 to a certain extent, thereby improving the overall rigidity of the connecting member 100 .

[0051] Reference Figure 2It can be understood that the inner taper of the tapered section 140 of the connecting member 100 is 5°±0.5°.

[0052] Specifically, the inner taper of the tapered section 140 of the connector 100 cannot be too large. An excessively large taper may easily result in an excessively small internal space of the connector 100 , thereby affecting material transportation.

[0053] Reference Figure 1 and 2 It can be understood that the small hole end 142 of the connecting member 100 is rounded.

[0054] Specifically, the fillet should be as large as possible and needs to be larger than the diameter of the braided wire used in the braid 300. By rounding the small hole end 142, the wear of the braid 300 can be effectively reduced and the braid 300 can be prevented from breaking.

[0055] In addition, the braided belt 300 can be woven into a tubular belt body by warp and weft, and its inner diameter and strength can be determined according to the use requirements, and then the number of warp threads, material, weft thread density and other parameters can be determined.

[0056] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. A person skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the principles of the present application shall be included within the scope of protection of the present application.
