The utility model discloses a pull type clamp pin with balanced stress, which comprises an outer sleeve, an inner rod, a spring, a knob and a movable positioning pin. The outer sleeve is fixed on the upper fixed frame, the upper end of the outer sleeve is provided with a spring limit retraction part, the inner rod is provided with a spring clamp part, the spring sleeve is on the inner rod, and is inserted into the outer sleeve together with the inner rod, so that one end of the spring is against the spring limit The other end of the necking part is against the spring clamp part; the outer end of the inner rod is connected with a knob, the inner end of the inner rod is provided with a movable locating pin installation rod, the movable locating pin is vertical to the inner rod, the middle part is provided with a ferrule part, both sides of the ferrule part are the clamp part, the ferrule part of the movable locating pin is sleeved at the installation rod of the movable locating pin, and is fixed by a nut. Compared with the prior art, the utility model has the advantages that: the clamp pin of the utility model forms two stress points through the clamp parts on both sides of the movable positioning pin, the stress is balanced, stable, and the safety is determined; the potential safety hazard can be avoided; the structure design is ingenious, and the cost is low.
【技术实现步骤摘要】
一种受力均衡的拉拔式卡销
本技术涉及销子,尤其涉及一种受力均衡的拉拔式卡销。
技术介绍
目前,市场上的拉销都是通过一个卡头卡在定位孔实现定位的,该结构的受力点仅仅在于卡头一点,用于一些大型/重型设备时,容易造成拉销变形,甚至断裂,从而造成意外,因此,研发一种受力均衡的拉拔式卡销,成为本领域技术人员亟待解决的问题。
技术实现思路
本技术是为了解决上述不足,提供了一种受力均衡的拉拔式卡销。本技术的上述目的通过以下的技术方案来实现:一种受力均衡的拉拔式卡销,包括外套管、内杆、弹簧、旋钮和活动定位销,所述外套管固定在上固定架上,外套管上端设有弹簧限位缩口部,内杆上设有弹簧卡部,所述弹簧套在内杆上,并连同内杆一起插入外套管中,使弹簧一端抵住弹簧限位缩口部,另一端抵住弹簧卡部;所述内杆外侧端连接旋钮,内杆内侧端设有活动定位销安装杆,所述活动定位销与内杆垂直,中部设有套圈部,套圈部两侧为卡部,活动定位销的套圈部套在活动定位销安装杆处,并通过螺母固定。进一步地,所述内杆中部设有中部螺纹,所述弹簧限位缩口部设有与内杆中部螺纹配合的缩口部内螺纹,使得拉出拉销时,可固定在解锁状态。进一步地,所述内杆根部设有根部螺纹,用于与缩口部内螺纹配合,将内杆固定在上锁状态。进一步地,所述外套管的外部设有套管外螺纹,所述上固定架一端设有固定拉销的内螺纹筒。本技术的操作装配和折叠过程:上锁时,活动定位销卡入拉销卡位(图中未示),并旋转旋钮使内杆上的根部螺纹锁紧在缩口部内螺纹与外套管紧固连接,即将卡销 ...
