Detailed description of the invention
Referring to figs. 1 through Fig. 6 to the utility model a kind of handwheel and apply the gate valve of this handwheel to be described further.
Embodiment 1: a kind of handwheel, as shown in Figures 1 to 4, including one in cylindrical wheel disc 1 and five in quadrangular arrange handles 2, handle 2 is uniformly distributed along the circumference of wheel disc 1, and handle 2 one end and wheel disc 1 is fixing is connected, the long side direction of handle 2 be arranged in parallel with the diametric(al) of wheel disc 1；It is fixedly connected with the gripper rings 6 of an annular at handle 2 away from one end of wheel disc 1, it is simple to workman carries fixed handle 2 to rotate by gripper rings 6.Offering multiple anti-slip tank 61 on the outer wall of gripper rings 6, anti-slip tank 61 is along the uniform setting in axle center of wheel disc 1.
As it is shown in figure 1, offer a through hole 21 along long side direction in handle 2, through hole 21 passes through gripper rings 6；Offering standing groove 22 on the side of handle 2, standing groove 22 connects setting with through hole 21.
All being equipped with the extension handle 3 of a root length bar shaped in each through hole 21, and extension handle 3 being placed in standing groove 22, extension handle 3 is slidably connected along through hole 21 with handle 2.
Wheel disc 1 is arranged with a columnar sliding set 4 and overlaps 4 matched in clearance with sliding, the outer wall of sliding set 4 is connected by connecting rod 5 near one end of wheel disc 1 with extension handle 3, connecting rod 5 is in strip, and the upper end of connecting rod 5 is hinged with sliding set 4, and lower end is hinged with extension handle 3；Five connecting rods 5 overlap, with sliding, the axial uniform setting that the junction of 4 overlaps 4 along sliding.
As shown in Figure 1, Figure 2 and Figure 3, wheel disc 1 offers two counterbores be arrangeding in parallel 71, two counterbores 71 arrange internal thread in arranging up and down along wheel disc 1 is axial on the inwall of counterbore 71, are sequentially placed into locating dowel the 72nd, elastic component 73 and regulating part 74 in counterbore 71；Locating dowel 72 is cylindrical, the hemispherical setting in one end of locating dowel 72, makes this end stretch out from counterbore 71；In the present embodiment, for the ease of producing, use spring as elastic component 73(it is also possible to use the resilient objects of tool such as rubber bar as elastic component 73)；Regulating part 74 is machine-processed rice screw so that machine-processed rice screw can be with the screw-internal thread fit on counterbore 71.
As shown in Figure 4, offering, on the inwall of sliding set 4, the shrinkage pool 75 matching with locating dowel 72, the one end making locating dowel 72 hemispherical can act against in shrinkage pool 75.
During use, as depicted in figs. 1 and 2, when by sliding set 4 along wheel disc 1 when axially from top to bottom moving, the inwall of sliding set 4 is conflicted with the locating dowel 72 of top, locating dowel 72 is made to apply pressure to spring, spring is made to produce deformation, locating dowel 72 axially moving toward the direction near machine-processed rice screw along counterbore 71, the one end making locating dowel 72 hemispherical separates with shrinkage pool 75, with continuing to move to of sliding set 4, make connecting rod 5 with the movement of sliding set 4, connecting rod 5 is made to promote extension handle 3 to move along through hole 21, so that five extension handles 3 can move simultaneously, increase workman's production efficiency；As in figure 2 it is shown, extension handle 3 stretches out from gripper rings 6；With continuing to move to of sliding set 4, making the shrinkage pool 75 on sliding set 4 match with the locating dowel 72 of lower section, spring applies elastic force to locating dowel 72, and elastic force is converted into the pressure to shrinkage pool 75 by locating dowel 72, and pressure is converted into frictional force so that sliding set 4 can position；So that workman can hold extension handle 3, and rotate handwheel by extension handle 3.
By regulation position in counterbore 71 for the machine-processed rice screw, the deformation quantity of spring can be regulated, such that it is able to play the purpose of regulation spring force, avoid that the elastic force of spring is excessive causes sliding set 4 that locating dowel 72 can not be promoted to move axially along counterbore 71, it is also possible to avoid causing because spring force is too small the locating dowel 72 cannot be to sliding set 4 positioning.
Owing to extension handle 3 adds workman's hand to the distance in wheel disc 1 axle center, i.e. add the arm of force so that workman rotate handwheel can be more laborsaving.
It in the present embodiment, in order to increase the structural strength of handle 2, between handle 2 and wheel disc 1, is fixed with reinforcement 11 so that handle 2 is not susceptible to fracture.
In the present embodiment, being provided with multiple anti-slip tank 61 on the outer wall of gripper rings 6, anti-slip tank 61 is along the axial uniform setting of wheel disc 1, and anti-slip tank 61 adds the frictional force of workman's hand and gripper rings 6 so that workman can be more convenient by gripper rings 6 rotating wheel disk 1.
Embodiment 2: a kind of handwheel, as shown in Figure 5, compared with Example 1, embodiment 2 eliminates the setting of spring, locating dowel 72 and machine-processed rice screw, by sliding set 4 radially offer a first putting hole (not shown), radially offer two the second putting holes 83 at wheel disc 1, axial in arranging up and down along wheel disc 1 of two the second putting holes 83；The axle center of the first putting hole and the second putting hole 83 is set in parallel.
First locking member 81 is passed through the first putting hole, the second putting hole 83 and the second locking member 82 coordinate, in the present embodiment, the first locking member 81 is screw, and the second locking member 82 is nut, can be to sliding set 4 positioning, it is to avoid sliding set 4 is axially arbitrarily mobile along wheel disc 1 because of external force effect.
During use, first nut is screwed out from screw, screw is separated with sliding set the 4th, wheel disc 1, as described in Example 1, sliding set 4 is moved down, after making extension handle 3 stretch out, makes sliding overlap the first putting hole on 4 and the second putting hole 83 of lower section is coaxial, screw is passed through the first putting hole and the second putting hole 83, then nut is screwed on screw.
Embodiment 1 is compared with embodiment 2, and the structure of embodiment 2 is relatively simple, and production cost is relatively low, but when needing to use extension handle 3 every time, needs to outward winding screw and nut, screws screw and nut after regulating sliding set 4 positions again, and step is relatively complicated；And embodiment 1 only needs workman move up and down sliding set 4 along wheel disc 1, and make shrinkage pool 75 coordinate with locating dowel 72, process is simple.
Embodiment 3: a kind of gate valve, as shown in Figure 6, including the handwheel of embodiment 1 or embodiment 2, also includes valve rod 91 and the flap 92 opening and closing for gate valve, valve rod 91 and the fixing connection of wheel disc 1.
During use, sliding set 4 is moved axially along wheel disc 1, make extension handle 3 to stretch out from handle 2 simultaneously, easy and simple to handle, add work task efficiency；Workman holds the extension handle 3 on handwheel, by extension handle 3 rotating wheel disk 1 so that wheel disc 1 drives flap 92 by valve rod 91 so that flap 92 is turned on or off gate valve.
Owing to extension handle 3 adds the arm of force of workman, even if institute is so that flap 92 also can easily be turned on or off gate valve in the case of getting rusty.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonging under the utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, the some improvements and modifications under the premise of without departing from the utility model principle, these improvements and modifications also should be regarded as protection domain of the present utility model.
