[0025] The structure of a kind of power fitting with protection provided by the present utility model is as Figure 1 and Figure 2 shown, including a lower clamping ring 1, an upper clamping ring 101 is arranged above the lower clamping ring 1, fastening screws 102 are arranged on both sides of the lower clamping ring 1, one end of the fastening screw 102 penetrates through the upper clamping ring 101 and is sleeved with a nut 103, the nut 103 is in threaded fit with the fastening screw 102, and a gasket 104 is sleeved on the surface of the fastening screw 102.
[0026] Furthermore, as Figure 2 and Figure 3 shown, protection mechanisms 2 are arranged on the surfaces of the lower clamping ring 1 and the upper clamping ring 101. The protection mechanism 2 is composed of a protection component 201 and a wear-resistant pad 202. Protection components 201 are arranged on the surfaces of the lower clamping ring 1 and the upper clamping ring 101, and a wear-resistant pad 202 is adhered to the surface of the protection component 201. An elastic sleeve 2011, a connecting pad 2012 and a stretching spring 2013 are arranged inside the protection component 201. Connecting pads 2012 are adhered to the inner walls of the lower clamping ring 1 and the upper clamping ring 101. An elastic sleeve 2011 is fixed to the surface of the connecting pad 2012. The surface of the elastic sleeve 2011 is adhesively fixed to the surface of the wear-resistant pad 202. Stretching springs 2013 are fixed inside the elastic sleeve 2011, and one end of the stretching spring 2013 is fixedly connected to the surface of the connecting pad 2012.
[0027] During use, place the cable to be fixed inside the lower clamping ring 1, then cover the upper clamping ring 101 onto the surface of the cable. Subsequently, pass one end of the upper clamping ring 101 through the fixing bracket, the lower clamping ring 1 and the upper clamping ring 101 in sequence. Then, slip the gasket 104 and the nut 103 onto one end of the fastening screw rod 102 in sequence, and then rotate the nut 103 to fix the upper clamping ring 101, the lower clamping ring 1 and the fixing bracket. At the same time, the cable is clamped under the action of the lower clamping ring 1 and the upper clamping ring 101. At this time, under the action of the extension spring 2013 and the elastic sleeve 2011, the extrusion force on the cable can be buffered and protected, and under the action of the wear-resistant pad 202, the protection component 201 is made more wear-resistant, so as to realize the protection function of the electrical fitting for the cable.
[0028] Furthermore, as Figure 4 shown, reinforcing mechanisms 3 are provided on both sides of the lower clamping ring 1 and the upper clamping ring 101. Insertion pieces 302 are fixed at both ends of the upper clamping ring 101, and a reinforcing component 301 is provided on the surface of the lower clamping ring 1. The inside of the reinforcing component 301 includes a screw barrel 3011, a turning handle 3012 and a fixing stud 3013. Fixing studs 3013 are fixed at both ends of the lower clamping ring 1. The fixing studs 3013 and the insertion pieces 302 are slidably matched with each other. One end of the fixing stud 3013 penetrates through the insertion piece 302 and is sleeved with a screw barrel 3011. The diameter of the screw barrel 3011 is larger than the width between the inner walls of the insertion piece 302. The screw barrel 3011 and the fixing stud 3013 are threadedly matched with each other. The surface of the screw barrel 3011 is in close fit with the surface of the insertion piece 302. A turning handle 3012 is fixed on the surface of the screw barrel 3011.
[0029] During use, when the upper clamping ring 101 is covered above the lower clamping ring 1, the reinforcing component 301 is sleeved on the surface of the fixing stud 3013. After the lower clamping ring 1 and the upper clamping ring 101 are fixed, the screw barrel 3011 can be sleeved on the surface of the fixing stud 3013, and then rotate the turning handle 3012 to drive the screw barrel 3011 to rotate. Since the diameter of the screw barrel 3011 is larger than the width between the inner walls of the insertion piece 302, the turning handle 3012 can tightly press the insertion piece 302 to fix the insertion piece 302, thereby reinforcing the lower clamping ring 1 and the upper clamping ring 101, so as to realize the reinforcement function of the electrical fitting for the lower clamping ring 1 and the upper clamping ring 101.
[0030] Furthermore, as Figure 3As shown in the figure, a stable placement mechanism 4 is provided at the bottom of the lower clamping ring 1. The stable placement mechanism 4 is composed of a placement rack 401 and a stable placement component 402. The placement rack 401 is fixed to the bottom of the lower clamping ring 1, and the stable placement component 402 is arranged on the surface of the placement rack 401. The inside of the stable placement component 402 includes a clamping plate 4021, a connecting spring 4022, and a chute 4023. A chute 4023 is provided on the surface of the placement rack 401, and the clamping plate 4021 is arranged inside the chute 4023. The clamping plate 4021 is slidably matched with the chute 4023. A connecting spring 4022 is fixed to one side of the clamping plate 4021, and one end of the connecting spring 4022 is fixedly connected to the inner wall of the chute 4023.
[0031] During use, place the lower clamping ring 1 on one side of the fixing bracket of the cable to be fixed. Then, pull the clamping plate 4021 to make the clamping plate 4021 away from one end of the placement rack 401. Then, put the placement rack 401 over the surface of the fixing bracket. Then, release the clamping plate 4021, so that the clamping plate 4021 clamps the fixing bracket under the driving force of the connecting spring 4022, and the clamping plate 4021 is guided by the chute 4023, so that the lower clamping ring 1 is stably placed on the surface of the fixing bracket to achieve the stable placement function of the electrical fitting.
[0032] Working principle: During use, first place the lower clamping ring 1 on one side of the fixing bracket of the cable to be fixed. Then, pull the clamping plate 4021 to make the clamping plate 4021 away from one end of the placement rack 401. Then, put the placement rack 401 over the surface of the fixing bracket. Then, release the clamping plate 4021, so that the clamping plate 4021 clamps the fixing bracket under the driving force of the connecting spring 4022, and the clamping plate 4021 is guided by the chute 4023, so that the lower clamping ring 1 is stably placed on the surface of the fixing bracket to achieve the stable placement function of the electrical fitting, thereby improving the stability of the electrical fitting during use.
[0033] Then, place the cable to be fixed inside the lower clamping ring 1, and then cover the upper clamping ring 101 on the surface of the cable. Then, pass one end of the upper clamping ring 101 through the fixing bracket, the lower clamping ring 1 and the upper clamping ring 101 in sequence. Then, put the gasket 104 and the nut 103 on one end of the fastening screw 102 in sequence, and then rotate the nut 103 to fix the upper clamping ring 101, the lower clamping ring 1 and the fixing bracket. At the same time, the cable is clamped under the action of the upper clamping ring 101 and the lower clamping ring 1. At this time, under the action of the extension spring 2013 and the elastic sleeve 2011, the extrusion force on the cable can be buffered and protected, and under the action of the wear-resistant pad 202, the protection component 201 is more wear-resistant, so as to achieve the protection function of the electrical fitting for the cable, so that the cable is not easily worn due to excessive extrusion force.
[0034] When the upper clamping ring 101 covers the lower clamping ring 1, the reinforcement member 301 is sleeved on the surface of the fixing stud 3013. After the lower clamping ring 1 and the upper clamping ring 101 are fixed, the screw barrel 3011 can be sleeved on the surface of the fixing stud 3013, and then the turning handle 3012 is rotated to drive the screw barrel 3011 to rotate. Since the diameter of the screw barrel 3011 is larger than the width between the inner walls of the insert piece 302, the turning handle 3012 can tightly press the insert piece 302 to fix the insert piece 302, thereby reinforcing the lower clamping ring 1 and the upper clamping ring 101, so as to realize the reinforcement function of the electric power fitting for the lower clamping ring 1 and the upper clamping ring 101, thereby improving the firmness of the electric power fitting during use, and finally completing the use work of the electric power fitting.
