The specific embodiment
Below in conjunction with accompanying drawing structure of the present utility model is further described in detail.
As shown in Figure 1, a kind of hand formula lifting device that the utility model provides comprises:
Lifting device body 7, the dual-side 61,51 of described lifting device body 7 forms the first relative notch 6 of opening and is used to wear second notch 5 of climbing rope (not shown in figure 1) to a lateral buckling respectively, offers rope button hole 4 respectively on two sidewalls of described second notch 5;
Grab rope cam 2, described rope cam 2 one ends of grabbing are hingedly fixed in described first notch 6, and the other end is a movable end, and described movable end can be rotated in described second notch 5 and compress described climbing rope;
Be used to control the described rope cam 2 of grabbing and be rotated into control handle 1 in described second notch 5, the outer wall of described control handle 1 one ends and described first notch 6 is hinged, and the other end and described movable end of grabbing the cam 2 of restricting are hinged.
During use, as shown in Figure 5, when climbing rope 20 is arranged in second notch 5, can stop that climbing the rope accident jumps out, and has prevented the generation of security incident in second notch 5 by in two rope button holes 4, wearing a safe (not shown in figure 1) of buckleing.In addition, also be provided with a fixing hole 71 on the top of lifting device body 7 of the present utility model and be used to hang fixedly lifting device.And button hole 9, button hole 10 that the bottom of lifting device body 7 is provided with can be used for further improving the security that lifting device uses, and one of them can buckle into foot-operated band, and another can buckle into the product that the bandlet that is connected with safety belt or Daisy chain etc. are drawn the rope class.
In the utility model, control handle 1 is to be used for control to grab rope cam 2 and be diverted to described second notch, 5 inward turnings and compress the climbing rope.During climbing, pin control handle 1 downwards and drive and grab rope cam 2 and compress the climbing rope.Have friction owing to grab between end face and the climbing rope of movable end of rope cam 2, thus the user can rely on lifting device climb and on; The described control handle 1 that only need come up during decline can be accomplished slow decline, and is easy to use, safe.In addition, during the actual use of hand formula lifting device of the present utility model, need characteristics, the basic identical but relation of mirror image symmetry each other on the structure with reference to the left hand and the right hand.And, left hand use with can being distinguished to make things convenient for the user with different colours respectively that the right hand uses.In the present embodiment, as preferably, described control handle 1 also is provided with is used to make the described back-moving spring 11 that rope cam 2 can screw out from described second notch 5 of grabbing when unclamping control handle 1 with the described rope cam 2 hinged ends of grabbing, described back-moving spring 11 1 ends are connected with described control handle 1, and the other end is connected with described described movable end of grabbing rope cam 2.Such structure is when rising, make and grab rope cam 2 when promptly climbing rope when the user presses control handle 1, back-moving spring 11 is in extended state, when needs are alternately changed lifting device upwards or climbing person's control handle 1 that only need come up need descend the time, under the effect of back-moving spring 11 elastic force, grab rope cam 2 and can slowly be pulled away from the climbing rope thereupon so that hand formula lifting device of the present utility model can be changed the fixed position on rope, and be equipped with back-moving spring 11 grab rope cam 2 normalities the time be in the release position, also can make things convenient for and singlehandedly on the climbing rope, install or remove lifting device.
Fig. 2 is the front view of grabbing the rope cam of the hand formula lifting device of an embodiment of the utility model.Fig. 4 is the front view of control handle of the hand formula lifting device of an embodiment of the utility model.As Fig. 2, shown in Figure 4, grab on rope cam 2 and the control handle 1 and be respectively arranged with fixing hole 23,24 and 13,14, be respectively applied for the described rope cam 2 of grabbing is connected with control handle 1 or with lifting device body 7.The projection 15 that is provided with on the described control handle 1 shown in Fig. 4 is used to connect back-moving spring 11.
As previously mentioned, as shown in Figures 2 and 3, the reason of using hand formula lifting device of the present utility model can conveniently climb rope is that lifting device itself can replace people's both hands tightly to buckle holding rope, and this critical component wherein is to grab rope cam 2 can clamp the climbing rope by frictional force.In the present embodiment, further, in order to promote described frictional force of grabbing between rope cam 2 and the climbing rope, play the effect of better firmly grasping stationary rope, as preferably, describedly grab the end face 22 that rope cam 2 can be rotated into an end of described second notch 5 and be provided with a plurality of ratchets 21 that are used to firmly grasp described climbing rope.Even this design make hand formula lifting device of the present utility model moist, freeze or muddy rope on use, it is also very outstanding to grab the rope ability.Further, as shown in Figure 3, describedly grab the end face 22 that rope cam 2 can be rotated into an end of described second notch 5 and be provided with dirt discharge groove 25.Like this freeze or muddy rope on when using hand formula lifting device also can by dirt discharge groove 25 easily the place to go dirt be beneficial to use.
As a rule, the configuration design of hand formula lifting device gets final product for ease of grasping, disclosed a kind of set lever 200 that device had of climbing rocks in the Chinese patent 200620113758.7 as shown in Figure 6.In embodiment of the present utility model, hand formula lifting device also can use in the mode of direct grasping, but as preferred, as shown in Figure 1, offer the hand-held hole 8 of holding that grips for the user on the described lifting device body 7, a described hand-held side of holding hole 8 forms gripping handle 3.And,, be arranged with gum cover 31 on the described gripping handle 3 as preferably.Being provided with of gum cover 31 can increase comfortableness when holding, and in extremely hot and ice and snow environment, can play and separate ice-cold or hot feel, especially for the user in low temperature ice and snow environment, can avoid not having the metal of glove hand and lifting device to stick together.
Hand formula lifting device of the present utility model applicable to: rescue, fire-fighting, military affairs, mountain-climbing, climbing, exploratory heading etc. need rope to rise and rope is gone up occasions such as location; as rising by dangerous area, precipitous landform, exploratory heading rises or during protection and the important self-protection equipment that is used of safety belt, main rope.
Certainly; the above is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection domain of the present utility model.
