[0023] The following is a detailed description of the embodiments of the utility model in conjunction with the accompanying drawings. It should be clear that the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-5 As shown, in some illustrative embodiments, a device for preventing a gas-filled hose from being thrown off is provided, comprising: a steel wire rope 1, a wire binding mechanism 2, a tightening clamp 3, a locking buckle 4, and an eight-shaped buckle 5.

[0025] The diameter of the steel wire rope 1 is 4 mm, which is neither too hard to make the gas filling hose 10 inconvenient to use, nor too strong to play a supporting role. At the same time, the outer sheath of the steel wire rope 1 is provided with a rubber soft sheath, which can play a protective role and avoid scratching the skin due to the rough surface of the steel wire rope 1.

[0026] The tightening clamp 3 is used to bind the steel wire rope 1 to the gas filling hose 10, so that the gas filling hose 10 can be fixed along the direction of the steel wire rope 1. When binding, the number of tightening clamps 3 is selected according to the actual length of the gas filling hose 10. Generally, a tightening clamp 3 is set every 30cm-40cm, and each tightening clamp 3 is evenly arranged on the gas filling hose 10 as much as possible to ensure that the force is more uniform. Among them, the tightening clamp 3 can use any existing clamp structure that can bind two tubular objects into one. Therefore, this article will not repeat the installation method of the tightening clamp 3.

[0027] Both ends of the steel wire rope 1 are bent back to the steel wire rope body, that is, the head parts of both ends of the steel wire rope 1 are bent and bent to the steel wire rope body, and are tightened with the steel wire rope body through the lock buckle 4 to form a first ring 101 respectively sleeved on the bottom end of the angle valve 11 and a second ring 102 sleeved on the top end of the angle valve 11, and the first ring 101 and the second ring 102 are each locked with a lock buckle 4. The lock buckle 4 can select any existing lock buckle structure dedicated to fixing steel wire ropes, so this article will not repeat the installation method of tightening the lock buckle 4.

[0028] Furthermore, sleeves 103 may be provided at both ends of the steel wire rope 1. The sleeves 103 may be of a sleeve structure with a greater hardness than the rubber sleeve. Two lock buckles 4 are respectively provided on the sleeves 103 at both ends of the steel wire rope 1, and both lock buckles 4 are connected to the steel wire rope body. The design of the sleeves 103 may increase the contact area between the lock buckle 4 and the steel wire rope 1, ensure sufficient friction, and reduce the probability of loosening.

[0029] The length of the first ring 101 is smaller than that of the second ring 102. The length here refers to the circumference of the two rings. More specifically, the length of the first ring 101 and the second ring 102 refers to the distance between the position of the buckle 4 and the position where the buckle 4 is bound to the wire rope body when the wire rope 1 is straightened. Since the first ring 101 is sleeved on the bottom end of the angle valve 11, the bottom end is the end where the angle valve 11 is connected to the gas source pipeline 12, and the first ring 101 is used as a force fixing point, the shorter length can ensure that the wire rope 1 will not fall off when subjected to strong disturbances. The second ring 102 is sleeved on the top of the angle valve 11. The second ring 102 with a longer length is convenient for connection with the filling connector 13 and for installation and removal of the gas cylinder.

[0030] The eight-shaped buckle 5 is used to fix the filling connector 13 to the second ring 102. During installation, one of the lock buckles in the eight-shaped buckle 5 is sleeved on the second ring 102, and the other lock buckle in the eight-shaped buckle 5 is sleeved on the filling connector 13. The eight-shaped buckle 5 can be an existing lock buckle in the shape of "8", and the two lock buckles in the eight-shaped buckle 5 are connected by a rotating shaft and can be rotated to change direction, so it is more convenient to adjust the direction of the filling connector 13 and connect it to the gas cylinder.

[0031] Since the placement of the gas cylinders is not fixed, in order to ensure that it can be connected to each gas cylinder, a longer length is reserved for the gas filling hose 10. The excessively redundant pipe length will swing more when the joint falls off, making it easier for the filling personnel to get injured. In addition, the longer pipe length also causes the wiring harness in the filling workshop to be messy, which is inconvenient to connect and will bring certain safety hazards. Therefore, in this embodiment, a wiring harness mechanism 2 is set on the wire rope 1, which can be used to coil and fix part of the gas filling hose 10 and adjust it to the most commonly used connection length. The gas filling hose 10 that is not frequently used can also be selectively coiled to the shortest length and mounted on the pipeline to save space and further reduce the risk of the joint falling off.

[0032] The cable harness mechanism 2 comprises: a soft board 6 , a locking block 7 , a binding belt, a locking rod, and a fixing clamp 8 .

[0033] There are two locking blocks 7, which are respectively arranged at the two ends of the soft board 6. A locking groove is provided at the top of the locking block 7, a binding strap is provided at the bottom of the locking block 7, and a locking rod adapted to the locking groove is provided at the end of the binding strap, that is, one end of the binding strap is connected to the bottom of the locking block 7, and the other end of the binding strap is connected to the locking rod. When in use, after the other end of the binding strap is passed around the steel wire rope 1 and the gas filling hose 10, the locking rod at the end of the binding strap is inserted into the locking groove, thereby fixing the coiled steel wire rope 1 and the gas filling hose 10 to prevent them from falling off.

[0034] The binding belt is composed of elastic belts 201 and arc plates 202 arranged alternately, that is, the elastic belts 201 and the arc plates 202 are arranged alternately and connected in sequence. The arc plates 202 are made of PVC or metal arc sheet structure, so that the binding belt as a whole can be in a circular shape, which is suitable for the coiled steel wire rope 1 and the gas filling hose 10, and the elastic belt 201 can be adaptively stretched to match different thickness size specifications.

[0035] The following is an explanation of the adaptation of the lock rod and the lock slot:

[0036] The side surface of the locking block 7 is provided with a first groove 701, and the top surface of the locking block 7 is provided with a second groove 702, the second groove 702 is connected with the first groove 701, and the width of the first groove 701 is greater than the width of the second groove 702. The locking rod comprises: a transverse locking rod 203 and a vertical locking rod 204 disposed on the transverse locking rod 203; the width of the transverse locking rod 203 is greater than the width of the second groove 702 and less than the width of the first groove 701; the width of the vertical locking rod 204 is less than the width of the second groove 702.

[0037] When the locking rod is inserted into the locking slot, the transverse locking rod 203 is inserted into the first groove 701, and the vertical locking rod 204 is inserted into the second groove 702, thereby completing the connection between the locking rod and the locking slot, and then realizing the fixation of the binding strap and the locking block 7, which has the advantages of simple operation, easy connection and disassembly, and stability after connection.

[0038] A hollow groove 703 is formed on one of the locking blocks at both ends of the soft board 6, and the fixing clamp 8 passes through the hollow groove 703 and is fixed to the steel wire rope 1 and the gas filling hose 10. The fixing clamp 8 can be any existing clamp structure that can bind two tubular objects into one, so this article will not repeat the installation method of the fixing clamp 8. The function of the fixing clamp 8 is to fix the cable tie mechanism 2 on the unwound steel wire rope 1 and the gas filling hose 10 in advance, and when winding is required, it can be directly operated and tightened with a strap.

[0039] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
