The utility model discloses a cover opener, which comprises a handle, a fastening strip, a locking gear, a positioning screw and an observation port. The outer circle of the handle is concave and convex, which is convenient for the fingers to grip; the fastening strip is flexible, with teeth or bumps on the inner side, which can effectively increase the surface friction; the outer teeth of the locking gear are engaged with the fastening strip, and the upper end is provided with a rotating clip. The tightening strip is arranged from the fixed end to the locking gear end in clockwise sequence. When in use, the tightening strip is sleeved on the outer circle of the bottle cap. By rotating the locking gear rotating clip, the tightening strip teeth are tightened on the bottle cap, and the rotating handle takes the bottle cap off the bottle body. There is a hole on the handle, and the rotation of the bottle cap can be observed. The utility model uses the lever principle, the friction principle and the tightening technology to overcome the bottle cap opening problem in life. The device is simple, low cost and easy to carry.
【技术实现步骤摘要】
一种开盖器
本专利技术涉及一种开盖器,属于生活用品领域。
技术介绍
现代社会人们日常生活中,瓶装食品与饮料越来越多,由于长时间保存需要,大多采用真空封盖,密封性得到了有效提升,但使用时瓶盖的开启却格外困难。同时,生活中一些带盖用品用具有时也存在瓶盖开启困难。专利(CN201620828117)公开了一种罐头启瓶器,利用杠杠原理达到了省力效果,但不是按照瓶盖螺旋旋转松开,对瓶盖有一定伤害,会使瓶盖变形。专利(CN201510539351)公开了用于罐头瓶盖的启瓶器,利用杠杆原理与摩擦力学开启瓶盖,但器型较大,不利于携带,制造成本较高。专利(CN201710064958)公开了一种新型罐头开盖器,利用摩擦力学原理进行开盖,但紧固条难于固定到瓶盖外沿,拉头紧固力不够,同时手动拧动紧固条费力,省力效果差。
技术实现思路
本专利技术的目的是利用杠杆原理,结合摩擦力学,通过结构设计提供一种开盖器。该装置结构简单,操作方便,直接套在瓶盖上,将瓶盖松开拧下。本专利技术采用的技术方案是:一种开盖器,包括手柄、紧固条、锁紧齿轮、定位螺钉、观察口。紧固条通过定位螺钉与手柄连接。锁紧齿轮由固定柱、卡扣、驱动轴、齿轮、锁紧螺母、旋转卡子、开口销组成。手柄便于手握住,外圆有手指握紧凹凸,手柄直径大于瓶盖直径,具有杠杆作用,拧动瓶盖时省力;紧固条具有柔韧性,内侧有凸点或齿结构,有效增大了紧固条与瓶盖外圆的摩擦力;锁紧齿轮外齿与紧固条咬合,上端有旋转卡子,通过旋转卡子转动锁紧齿轮,利用杠杆作用轻松使紧固条箍紧瓶盖。紧固条 ...
