Abstract
The utility model discloses a two-way ratchet device. The two-way ratchet device comprises a frame, a ratchet and a pawl, and is characterized in that the ratchet is connected with the shaft of an apparatus through a key joint; the pawl has a shoe-shaped structure and includes two ratchet teeth; the pawl is arranged on a control shaft; the control shaft is arranged on the frame; an operating rod is arranged at the outer side end of the control shaft; a spring location device is disposed on the support, and includes a ball; and the ball is in contact with the pawl when pushed by the spring. The ratchet has a rectangular groove. The two-way ratchet device has the advantages of simple structure, convenient operation, high operation reliability of the ratchet, and can achieve two-way intermittent movement to meet the requirement for transmission of moderate loads.
Description
Technical field
The utility model belongs to the ratchet unit in the mechanical transmissioning technology, is specifically related to a kind of two-way ratchet unit, is used for the two-way intermittent movement of some equipment special, can bear the transmission of medium load.
Background technique
Ratchet mechanism is used more in mechanical transmissioning technology and hardware ﹠ tools field, use more extensive with single direction ratchet in traditional ratchet mechanism, two-way ratchet is used in hardware ﹠ tools more (as two-way ratchet spanner), these ratchet mechanisms exist ratchet little, ratchet is thin, pivot pin intensity is little, can not bear than high pulling torque.But along with the development of technology, the ratchet mechanism of high-performance, high moment of torsion is the technical problem that the prior art personnel need to be resolved hurrily.At notification number CN201195291 on February 18 2009 day for announcing, a kind of bidirectional ratchet mechanism is disclosed, comprise that ratchet (5) two ends are provided with two back-up rings (6) of ratchet (5) retaining in through hole, ratchet (5) is provided with nut and pulls hole or square tenon and mechanical workpieces (4), on the plane that handle (2) one end thickness equate, be provided with a two center of circle A, the B through hole, with center of circle A, during B connection elongation line meets on through hole one end R or the r hole wall and is, symmetry radially is provided with one to 20 internal tooth (3) on hole wall, being built-in with at through hole can be along center of circle A, the B direction moves back and forth, and with hole wall on one to 20 internal tooth (3) be meshing with each other, can be radially suitable jointly, de-rotation with separate the ratchet (5) that can rotate alone, described handle (2) medium line is handle center's line (1).There is complex structure in this patent structure, can not bear the shortcoming than high pulling torque.
The model utility content
For solving the above-mentioned defective that prior art exists, it is a kind of simple in structure, easy to operate that the purpose of this utility model is to provide, and can make mechanism realize two-way intermittent movement, can bear the two-way ratchet unit of medium load transmission demand.
For achieving the above object, the technical solution adopted in the utility model: this two-way ratchet unit, have support, ratchet and pawl, it is characterized in that: described ratchet by key connecting equipment the axle on, described ratchet is an ingot-shaped, have two ratchets, ratchet is located on the Control Shaft, Control Shaft is located on the support, the outboard end of Control Shaft is provided with operating handle, support is provided with spring-positioning device, and described spring-positioning device has and the contacted pellet shot from a slingshot of ratchet, and pellet shot from a slingshot promote to be kept and the contacting of ratchet by spring.
Described ratchet is the ratchet of rectangle groove.
Adopt the beneficial effect of technique scheme: the ratchet of this two-way ratchet unit is an ingot-shaped, have two ratchets, ratchet is connected with operating handle by Control Shaft, move operating handle and can drive ratchet clockwise or be rotated counterclockwise several angle, ratchet is snapped in the rectangle groove of ratchet, the clockwise or counterclockwise one-way intermittent of axle rotates on the realization equipment, support is provided with spring-positioning device, after direction rotation, it is spacing that spring promotes pellet shot from a slingshot, and ratchet is locked at ratchet.Simple in structure, easy to operate, the ratchet operational reliability is good, can make mechanism realize two-way intermittent movement, the ratchet of rectangle groove and ingot-shaped click-fit, and under the effect of positioning device, can bear medium load transmission demand.
Description of drawings
Below in conjunction with accompanying drawing specific embodiment of the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Embodiment
Two-way ratchet unit as shown in Figure 1, 2 has support 2, and support 2 is fixed on the equipment rack by fastening piece, and the axle 1 of equipment connects with ratchet 3 by key 4, and described ratchet is the ratchet of rectangle groove, and ratchet 3 is spacing fastening with ratchet 3 by two setting sleeves 10.Ratchet 9 is an ingot-shaped, have two ratchets, ratchet cooperates with ratchet realizes unidirectional intermittent movement, ratchet 9 is located on the Control Shaft 5, and Control Shaft 5 is located on the support 2, and Control Shaft stretches out support 2, its outboard end is provided with operating handle 6, stir operating handle 6 and can drive ratchet clockwise or be rotated counterclockwise several angle, ratchet is snapped in the rectangle groove of ratchet, realize two-way intermittent movement.Support 2 is provided with spring-positioning device, and described spring-positioning device has and the contacted pellet shot from a slingshot 8 of ratchet, and pellet shot from a slingshot 8 is promoted to keep and the contacting of ratchet 9 by spring 7.During work, the driving power pulling operating handle 6 with manual or other power plant (as electronic cylinder, cylinder, oil hydraulic cylinder) provide drives ratchet 9 to direction rotation, and it is spacing that spring 7 promotes pellet shot from a slingshot 8, and ratchet 9 is locked, and realizes unidirectional intermittent movement.When need during, only need a reverse pull joystick to realize to the reverse intermittent movement of other direction.
Claims (2)
1. two-way ratchet unit, have support, ratchet and pawl, it is characterized in that: on the axle of equipment, described ratchet is an ingot-shaped to described ratchet, has two ratchets by key connecting, ratchet is located on the Control Shaft, Control Shaft is located on the support, and the outboard end of Control Shaft is provided with operating handle, and support is provided with spring-positioning device, described spring-positioning device has and the contacted pellet shot from a slingshot of ratchet, and pellet shot from a slingshot promote to be kept and the contacting of ratchet by spring.
