Abstract
A kind of ratchet locking device, including the loosening device being mounted on the outside of ratchet, the loosening device includes the pawl of rotation setting, the easy off-axis that the lower part setting of pawl limits the ratchet of ratchet.Pawl is fixed by the rotation of pawl shaft.The utility model can limit the reversion of bolt pair, realize the effective locking of bolt pair after stud is locked.The easy off-axis of pawl can only bear constantly acting load, more than just automatically cutting off after this load, eliminate the restriction effect to ratchet.Easy off-axis is conveniently replaced, and after the cutting of easy off-axis, the easy off-axis more renewed can restore ratchet locking function.
Description
Technical field
The utility model belongs to machinery field, and in particular to a kind of ratchet locking device.
Background technique
In normal screw thread link, the supporting surface frictional force of screw rod and bolt head has locking functions, thus in dead load and
When temperature change is little, screw thread link will not loosen automatically.But under the action of shock and vibration or varying load, screw pair
Frictional force may reduce or pop-off, this phenomenon multiplicating will be such that screw pair connection loosens.
Locking basic goal is to prevent screw pair from relatively rotating when loaded, locking at this stage mainly to have machinery
The locking and two methods such as locking that rub.Mechanical locking link robust can bear biggish shock and vibration, but machinery is locking not
It is easily disassembled, especially in automatic production line, it is sometimes desirable to connecting portion is dismounted using manipulator, it is mechanical at this time
It is locking to be just not easily accomplished mechanization and automation.It rubs locking simple, conveniently, but without mechanical locking reliable, in key
Position be not suitable for use.
Therefore, develop a kind of reliable locking and easy to disassemble, the locking device for being suitble to automatic and mechanical to promote very must
It wants.
Utility model content
The utility model patent is designed to provide the ratchet locking device that a kind of structure is simple, easy to use, Ji Keshi
It is now reliable locking, but can in later period use fast quick-detach, it is convenient in mechanization and automatic batch production to be particularly suitable for
Disassembly.
The utility model uses following technical scheme:
A kind of ratchet locking device, the loosening device including being mounted on 4 outside of ratchet, the loosening device include that rotation is set
The pawl 3 set, the easy off-axis 5 that the lower part setting of pawl 3 limits the ratchet of ratchet 4.
The pawl 6 is fixed by the rotation of pawl shaft 3.
The positioning pin 2 limited to the hunting range of pawl is set between the pawl 6 and ratchet 4.
The outside of the pawl 6, which is provided with, oppresses the plate spring sheet 7 on ratchet for pawl 6.
The plate spring sheet 7 is fixed on bracket (8).
The easy off-axis 5 is removably mounted on pawl 6.
The utility model has the beneficial effects that
(1) reversion of bolt pair can be limited, realizes the effective locking of bolt pair after stud is locked.
(2) the easy off-axis of pawl can only bear constantly acting load, more than just automatically cutting off after this load, eliminate to ratchet
Restriction effect.
(3) easily off-axis is conveniently replaced, and after the cutting of easy off-axis, the easy off-axis more renewed can restore ratchet locking function.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model.
Fig. 2 is the stereoscopic schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
The utility model provides a kind of ratchet locking device, the loosening device including being mounted on 4 outside of ratchet, loosening device
Pawl 3 including rotation setting, the easy off-axis 5 that the lower part setting of pawl 3 limits the ratchet of ratchet 4.
The side of ratchet 4 is arranged in pawl 6, and an end of pawl 6 is fixed by the rotation of pawl shaft 3, another end
Easy off-axis 5 is arranged in portion can be by easy off-axis 5 to ratchet position when pawl 6 is turned under external force at the ratchet of ratchet 4
It sets and is defined, and the easy off-axis 5 of pawl 6 may be configured as to bear the axis of constantly acting load, after being more than the load of setting just
It automatically cuts off, eliminates the restriction effect to ratchet.And easily off-axis is detachably arranged on pawl 6, and it is conveniently replaced, in easy off-axis
After cutting, the easy off-axis more renewed can restore ratchet locking function.
Pawl 6 can be swung around pawl shaft 3, and the rotation in one direction of ratchet can be limited by easy off-axis 5.
The above-mentioned power for giving the rotation of pawl 6 selects as needed, and torsional spring or spring with reset function may be selected,
Can also be as shown in Figure 1 and 2, it is alternatively provided at the plate spring sheet 7 in 6 outside of pawl, one end of plate spring sheet 7 is fixed on bracket 8, separately
One end is attached to the outside of pawl 6, oppresses pawl 6 by plate spring sheet and is closely fitted on ratchet 4, pawl 6 is fixed.
The positioning pin 2 limited to the hunting range of pawl 6 is set between pawl 6 and ratchet 4, and positioning pin 2 limits spine
Pawl movement, pawl can only be swung in a certain range.
The specific implementation process of the utility model can be as depicted in figs. 1 and 2, ratchet 4 and locking stud 1 be connected by key or
Other types of attachment realize close link, and can be rotated with locking stud 1, and pawl 6 limits ratchet 4 such as by easy off-axis 5
Anticlockwise rotation shown in FIG. 1, clockwise rotation are unrestricted.During normal locked, stud 1 is locked
Bolt pair it is unrestricted, can normally lock.And lock stud 1 it is locked after, ratchet mechanism can limit the reversion of bolt pair, can be real
Now bolt pair is effective locking.
Easy off-axis 5 is made using the lesser material of bearing capacity, can be in screw rod in the equipment disassembly process in later period
One reversed torque of upper load, when this torque is greater than the bearing capacity of easy off-axis, easy off-axis 5 is cut off, and is released to ratchet 4
Limitation.It is further swung in addition, positioning pin 2 limits pawl 6, prevents pawl 6 and ratchet 4 from interfering, locking stud 1 is made to exist
It can be freely rotated in positive and negative both direction, release the locked effect to clamping screw.
When locking stud 1 needs to reuse, the easy off-axis 5 more renewed can restore locking function.5 structure of easy off-axis
Simply, extensively, cost of manufacture is lower for materials, and replacement is got up more convenient.
Above-described is only preferred embodiments of the present invention, it is noted that for those skilled in the art
For, under the premise of not departing from the utility model general idea, several changes and improvements can also be made, these also should be considered as
The protection scope of the utility model.
