The utility model discloses a double locking cylinder, which comprises a cylinder cylinder, a front cover and a rear cover arranged at the front and rear ends of the cylinder cylinder, a piston and a piston rod arranged in the cylinder cylinder, the piston rod and the piston are connected, the front cover and the rear cover are provided with air inlets, the front cover and the rear cover are provided with locking components, and the piston and the piston rod are arranged on the front cover and the rear cover. The locking assembly of the front cover is separated from the locking head of the piston rod into a first state when the locking assembly of the rear cover is locked with the locking head of the piston rod, and the locking assembly of the front cover is locked with the piston rod when the locking assembly of the rear cover is locked with the locking head of the piston rod. The head is separated into this second state, and the front cover and the rear cover air intake cause the double locking cylinder to switch between the first state and the second state. The double locking cylinder of the utility model can improve the response sensitivity, prevent the lock core and the lock head from breaking and twisting, and has long service life and convenient maintenance.
【技术实现步骤摘要】
双锁紧气缸
本技术涉及机械领域,特别是涉及一种环卫车用双锁紧气缸。
技术介绍
现有的锁紧气缸一般为单锁气缸,气缸采用锁端对气缸进行锁定,由于气缸自重和较重负载导致气缸承受扭力较大,且受力不平衡,材料问题,导致锁头和锁芯经常出现扭曲、断裂现象,使用寿命较短,同时完成依靠手动操作的解锁功能,操作维修不方便。
技术实现思路
本技术主要解决的技术问题是提供一种双锁紧气缸,能够提高反应灵敏度,防止锁芯和锁头断裂、扭曲,使用寿命长,维护方便。为解决上述技术问题,本技术采用的一个技术方案是:提供一种双锁紧气缸,包括缸筒,设于缸筒前后两端的前盖和后盖,设于缸筒内的活塞和活塞杆,所述活塞杆和活塞相连接,所述前盖和后盖上具有进气口,所述前盖和后盖上设有锁紧组件,所述活塞和活塞杆上具有锁头,所述锁头与锁紧组件接触以锁合或者分离以解锁,所述前盖的锁紧组件与活塞杆的锁头锁合时,后盖的锁紧组件与活塞的锁头分离此为第一状态,后盖的锁紧组件与活塞杆的锁头锁合时,前盖的锁紧组件与活塞的锁头分离此为第二状态,所述前盖和后盖进气使双锁紧气缸在第一状态和第二状态之间进行切换。在本技术一个较佳实施例中,所述锁 ...
