worm drive hose clamp is a fastener at the pipe connection. It solves the problems of dead angle, liquid and gas leakage when hoops are used in small diameter pipe connection in the existing technology. It is widely used in the matching parts of motor vehicles, petrochemical, pharmaceutical, food and wine making sewage treatment, purification and dust removal, automobile accessories and other machines. Hoop is generally composed of hoop, hoop shell and worm. Hoop shell is installed at the end of hoop belt, worm is installed in hoop shell, the other end of hoop belt is inserted under the inner worm of hoop shell, and several transmission holes are distributed on the hoop. Worm can realize the adjustment of ring clamp tightness by engaging with transmission hole through forward rotation and reverse rotation. However, the traditional hoop worm structure is relatively single, which is composed of worm head and transmission fastening rod. There is a groove at both ends of the transmission fastening rod, the worm head is made at one end of the transmission fastening rod and a retaining head is made at the other end of the transmission fastening rod. Because of the limitation of the worm structure, the worm and the hoop are closely meshed, which makes the ring clamp rotate the worm continuously for a long time, one screw and one fastening, which is very inconvenient to operate, and reduces the fastening efficiency.

The purpose of the invention is to overcome the shortcomings of the existing technology, and to provide a quick mounted worm drive hose clamp with scientific design, convenient operation and high fastening efficiency. The technical problem of the worm drive hose clamp of the utility model is realized by adopting the following technical scheme: a fast mounted worm drive hose clamp hoop, including a hoop, a hoop shell and a worm, a hoop shell is installed at the end of the hoop, and a worm is installed in the hoop shell, which includes worm head, transmission fastening rod and retaining head, and the worm head and the retaining head are respectively installed at both ends of the transmission fastening rod, A card groove and a two clamp groove are respectively made at both ends of the transmission fastening rod. The worm drive hose clamp is characterized in that it also includes a boss and a two boss, the said boss is arranged between the worm head and the first card groove, and the two bosses are arranged between the retaining head and the second clamp groove. Moreover, the convex table is a conical boss. Moreover, the two bosses are a conical boss. The advantages and positive effects of the worm drive hose clamp of the utility model are: 1. the quick mount worm drive hose clamp is in the groove of the worm without the tightening force. Because of the design of the boss, there is a gap between the transmission fastening rod and the hoop of the worm, so that the hoop can be dragged to the position to be fastened directly when using, Then, the raised parts of the hoop shell are moved from the groove to the boss to realize the fastening of the hoop. The design of the hoop avoids the previous fastening adjustment by fastening one by one because there is no gap between worm and band, which is convenient to use and greatly improves the fastening efficiency. 2. the structure design of worm drive hose clamp is scientific and reasonable, and has the advantages of convenient operation, high fastening efficiency, large fastening quantity and strong practicability, and is a fast mounted worm driven hose clamp with high innovation.
Working principle of worm drive hose clamp: the snap ring of the quick mounted worm drive hose is in the groove of worm without the tightening force. Because of the design of boss, there is a gap between the transmission fastening rod and the hoop of worm, so that the hoop can be dragged to the position to be fastened directly when using, Then screw down the screw to move the protrusions at both ends of the hoop shell from the groove to the boss to realize the fastening of the hoop. Although embodiments and drawings of the utility model are disclosed for illustrative purposes, those skilled in the art can understand that various replacement, change and modification are possible without departing from the spirit and scope of the utility model and the appended claims.
