Detailed Description
The present invention will now be described more fully hereinafter with reference to the accompanying examples.
Referring to figure 1 of the drawings, an elastic hose clamp comprises two clamping strap sections 1, an elastic sheet 2 and a fastening connection.
Referring to fig. 2, the clamping hoop section 1 is a semicircular arc structure as a whole, a clamping groove 3 penetrating through the clamping hoop section 1 in the length direction is formed on the clamping hoop section 1, and the clamping groove 3 is a trapezoidal structure. Two centre gripping hoop sections 1 are articulated each other, and connecting hole 4 has all been seted up to two centre gripping hoop sections 1 one end of keeping away from articulated department, and one of them connecting hole 4 is the rectangle structure, and another connecting hole 4 is circular structure.
Referring to fig. 3, the elastic sheet 2 is of a zigzag structure to provide a greater resilient force and facilitate wrapping of the hinge of the two clamping hoop sections 1. The elastic sheet 2 is fixedly connected with one clamping hoop section 1 through a welding point 12, and is abutted against the other clamping hoop section 1, the elastic sheet 2 is provided with a limiting groove 5, the clamping hoop section 1 which is not fixed with the elastic sheet 2 is fixedly provided with a clamping hook 6, the clamping hook 6 is arranged in the limiting groove 5 in a penetrating manner, and the clamping hook 6 can be clamped with the limiting groove 5 after the two clamping hoop sections 1 are buckled.
Referring to fig. 4 in combination with fig. 1, the fastening connection portion includes a fastening bolt 7 and a fastening nut 8, and the fastening bolt 7 is inserted into the connection hole 4. Two elastic lugs 9 are fixedly arranged on the fastening nut 8, the elastic lugs 9 are arranged in the connecting holes 4 of the rectangular structure in a penetrating mode, and the fastening nut 8 is connected with the clamping hoop section 1 through the elastic lugs 9. When the fastening bolt 7 is unscrewed, the fastening nut 8 can still be left on the clamping hoop section 1, and the convenience for disassembling and assembling the elastic hose clamp is effectively improved. And when the fastening bolt 7 is screwed, the fastening nut 8 cannot rotate relatively, so that the elastic hose clamp is convenient to mount and fasten.
The fastening bolt 7 is sleeved with a plurality of gaskets 10, each gasket 10 is of a bowl-shaped structure, the two gaskets 10 are buckled together to be used in pairs, and the gaskets 10 are located between the head of the fastening bolt 7 and the corresponding clamping hoop section 1. The gasket 10 can provide elastic force, and compared with the traditional spring washer, the gasket 10 can be used in many-to-one mode, and the elastic force can be effectively increased. The fastening bolt 7 is connected with a limiting ring 11 through threads, the limiting ring 11 is made of elastic materials, and the limiting ring 11 is located between the two clamping hoop sections 1.
