Abstract
Description
本創作為有關梯具扶手或工作平台護欄的固定裝置,更具體的說為有關可快速夾緊及鬆釋梯具扶手或工作平台護欄的固定裝置。 This work is about fixtures for ladder handrails or work platform guardrails, more specifically about fixtures that can quickly clamp and release ladder handrails or work platform guardrails.
一般傳統固定梯具扶手或工作平台護欄的方式,大都先於梯具扶手或工作平台護欄的固定端鑽設固定孔,再將該固定端插入設於梯具或工作平台的固定座,該固定座也設有必須對準前述梯具扶手或工作平台護欄固定端所鑽設的固定孔,最後以螺絲或插銷等鎖扣件,將梯具扶手或工作平台護欄的固定端固定於固定座。此種以螺絲或插銷等鎖扣件伸通固定孔的習用固定方式,不但有必須對齊固定孔,造成組裝不易的缺點外,另有無法確實固定梯具扶手或工作平台護欄,容易產生搖晃及不穩定的問題,對使用者而言,極為不安全,令人堪慮。再者,為能達到方便對齊固定孔,加大所鑽的固定孔的孔徑,是常有的現象,如此更惡化被固定的梯具扶手或工作平台護欄的不穩定性。 Generally, the traditional way of fixing ladder handrails or work platform guardrails is to drill a fixed hole in the fixed end of the ladder handrails or work platform guardrails, and then insert the fixed end into the fixed seat provided on the ladder or work platform. The seat is also provided with a fixing hole that must be drilled on the fixed end of the ladder handrail or the working platform guardrail, and finally, the fixing end of the ladder handrail or the working platform guardrail is fixed to the fixed seat with screws or latches. This conventional fixing method in which the locking parts such as screws or bolts extend through the fixing holes not only has to align the fixing holes, resulting in the disadvantage of not easy assembly, but also cannot reliably fix the ladder handrail or the work platform guardrail, which is easy to produce shaking and The problem of instability is extremely unsafe for users, which is worrying. In addition, in order to facilitate the alignment of the fixing holes, it is a common phenomenon to increase the diameter of the drilled fixing holes, which further worsens the instability of the fixed ladder handrails or working platform guardrails.
針對上述習用固定方式的缺失,本創作提出一種可快速夾緊及鬆釋梯具扶手或工作平台護欄的固定裝置,利用具有夾筒的固定座及凸輪把手結合的夾緊方式取代螺絲或插銷與固定孔結合的固定方式,不但可快速夾緊梯具扶手或工作平台護欄,也可快速鬆釋梯具扶手或工作平台護欄,尚且因不需使用習用的固定孔,無固定孔對齊問題,同時也無梯具扶手或工作平台護欄搖晃及不穩的問題。 In view of the above-mentioned lack of conventional fixing methods, this creation proposes a fixing device that can quickly clamp and release ladder handrails or work platform guardrails, using a clamping method combined with a fixed seat with a clamp and a cam handle to replace screws or pins and The fixing method combined with the fixing holes can not only quickly clamp the ladder handrails or working platform guardrails, but also quickly release the ladder handrails or working platform guardrails, and because there is no need to use conventional fixing holes, there is no fixing hole alignment problem. There is no problem of shaking and instability of ladder handrails or working platform guardrails.
本創作的可快速夾緊及鬆釋梯具扶手或工作平台護欄的固定裝置包含一固定座,一墊圈,一彈簧,一螺帽,一螺桿及一凸輪把手;固定座設一具有一長開口的夾筒,鄰近長開口兩側的夾筒處,往外伸出兩彼此相對且平行的第一夾板及第二夾板,第一及第二夾板分別設一彼此對應的第一通孔及第二通孔;墊圈位於第一夾板外邊對應第一通孔,彈簧位於第一及第二夾板間,兩端分別接觸第一及第二夾板且分別對應第一及第二通孔;螺帽位於第二夾板外邊對應第二通孔;螺桿有一螺紋段及其一具有連接孔的連接端,螺紋段依序通過墊圈,第一通孔,彈簧及第二通孔而自第二夾板伸出,並與螺帽螺合;凸輪把手設有開叉凸輪部與把手部,開叉凸輪部具有偏心軸孔對應螺桿的連接端的連接孔,藉由樞軸組合將螺桿的連接端與開叉凸輪部可樞轉的結合一起。 The fixed device for quickly clamping and releasing ladder handrails or working platform guardrails in this creation includes a fixed seat, a washer, a spring, a nut, a screw and a cam handle; the fixed seat is provided with a long opening The clamps, adjacent to the clamps on both sides of the long opening, extend outward two parallel and parallel first and second clamping plates, the first and second clamping plates are respectively provided with a first through hole and a second corresponding to each other The through hole; the washer is located on the outer side of the first splint corresponding to the first through hole, the spring is located between the first and second plywood, the two ends contact the first and second plywood respectively and correspond to the first and second through holes respectively; The outer edge of the second splint corresponds to the second through hole; the screw has a threaded section and a connecting end with a connecting hole, the threaded section extends through the washer, the first through hole, the spring and the second through hole from the second splint in sequence, and Screwed with the nut; the cam handle is provided with a split cam portion and a handle portion. The split cam portion has an eccentric shaft hole corresponding to the connecting end of the screw, and the connecting end of the screw and the split cam portion can be combined by a pivot Pivot together.
此外,本創作的可快速夾緊及鬆釋梯具扶手或工作平台護欄的固定裝置中的夾筒的內緣面設有複數等間距的平行夾條延伸至夾筒兩端,增進夾緊效果。 In addition, the inner edge surface of the clamping cylinder in the fixing device of the invention can quickly clamp and release the ladder handrail or the guardrail of the working platform is provided with a plurality of parallel clamping strips at equal intervals extending to both ends of the clamping cylinder to improve the clamping effect .
當一梯具或工作平台的固定端部插入本創作的可快速夾緊及鬆釋梯具扶手或工作平台護欄的固定裝置的夾筒時,手握凸輪把手,往 順時針方向旋轉,令其開叉凸輪部抵壓墊圈,該抵壓的力量迫使第一及第二夾板彼此往相對方向移近,進而令夾筒快速夾緊及固定梯具扶手或工作平台護欄的固定端部。 When the fixed end of a ladder or working platform is inserted into the clip tube of the creative device that can quickly clamp and release the fixing device of the ladder handrail or the working platform guardrail, hold the cam handle to Rotate clockwise so that the split cam portion presses against the washer. This pressing force forces the first and second clamping plates to move closer to each other, thereby quickly clamping and fixing the ladder handrail or working platform guardrail. Of the fixed end.
當梯具扶手或工作平台固定端部要從夾緊狀態行拆卸操作時,逆時針方向旋轉凸輪把手,令其開叉凸輪部不再抵壓墊圈,第一及第二夾板因不再受力,往相反方向移動,在此同時,藉由彈簧的反彈力,快速撐開第一及第二夾板及鬆該夾筒,令梯具扶手或工作平台固定端部可以被快速抽離夾筒。 When the handrail of the ladder or the fixed end of the working platform is to be disassembled from the clamped state, rotate the cam handle counterclockwise so that the split cam portion no longer presses the washer, and the first and second clamping plates are no longer stressed , Move in the opposite direction, at the same time, by the spring rebound force, quickly open the first and second clamping plates and loosen the clamping cylinder, so that the fixed end of the ladder handrail or working platform can be quickly pulled away from the clamping cylinder.
