Abstract
The invention discloses a handle locking device. The handle locking device comprises a handle rod, a barrel, a locking rod, springs and locating claws. The handle rod is located in the barrel in a sliding connection mode. A locating pin is arranged on the side face of the handle rod. The handle rod is sleeved with a bearing. The inner circle of the bearing is fixedly connected with the end, located outside the barrel, of the handle rod. The outer circle of the bearing is fixedly connected with a connecting rod. A strip-shaped hole is formed in the side face of the barrel in the axial direction of the barrel. The width of the strip-shaped hole is larger than the diameter of the locating pin. The locating pin is located in the strip-shaped hole in a sliding connection mode. The locking rod is also located in the strip-shaped hole. Grooves are formed in the locking rod. The springs are connected between the inner wall of the strip-shaped hole and the locking rod. When the springs are in the natural state, the side face of the locking rod can be abutted against the locating pin. The locating claws are hinged to the barrel and can rotate in the circumferential direction of the barrel. The locating claws can stretch into the grooves of the locking rod. When the locating claws stretch into the grooves of the locking rod, the springs are in the compressed state. All the components of the handle locking device are connected to the handle rod or the barrel, thereby being unlikely to be lost.
Description
Technical field

The present invention provides a kind of hand locking device, to solve existing hand locking device, when being locked, fix bar
Easy to lose, thus affecting the problem of handle locking.
For reaching above-mentioned purpose, technical scheme is as follows: a kind of hand locking device, including handlebar, cylinder,
Securing rod, spring and locating detent, handlebar is slidably connected in cylinder, and the side of handlebar is provided with alignment pin, and handlebar covers
It is provided with bearing, one end that the inner ring of bearing is located at outside cylinder with handlebar is fixedly connected, the company of being fixedly connected with the outer ring of bearing
Bar；The side of cylinder axially has bar hole along it, and the width of bar hole is more than the diameter of alignment pin, and alignment pin is slidably connected to
Bar shaped in the hole；Described securing rod also is located at bar shaped in the hole, and securing rod has groove, and spring is connected to inwall and the lock of bar hole
Between fixed pole, under spring naturalness, the side of securing rod can be offseted with alignment pin；Locating detent is hinged on cylinder, positioning
Pawl can circumferentially rotating along cylinder, when locating detent can stretch in the groove of securing rod, locating detent stretches in the groove of securing rod, bullet
Spring is in compressive state.
In this programme, the principle using bearing is: handlebar slides in cylinder, and alignment pin can be used for determining of handlebar
Position, connecting rod is used for controlling corresponding component.Handlebar can be slided in the state of not offseted with securing rod along the axial and circumferential directions,
But it is provided with bearing between handlebar and connecting rod, circumference is slided and will not be transferred on connecting rod, and only axial slip just can be transmitted
To connecting rod.
Compared with prior art, it is an advantage of the current invention that: 1, handlebar is slidably connected in cylinder, the side edge of cylinder
It axially has the bar hole that width is more than alignment pin diameter, and alignment pin can freely activity, drive in the range of bar hole
Handlebar activity in corresponding scope.2nd, bar shaped in the hole is provided with securing rod, when locating detent does not extend in the groove of securing rod,
Spring is naturalness, and the side of securing rod can be offseted with alignment pin, and alignment pin is locked bar positioning, and handlebar also will not be in cylinder
Internal slip.When locating detent stretches in the groove of securing rod, spring is in compressive state, securing rod not with positioning pin contacts,
Handlebar freely activity in corresponding scope.3rd, locating detent is hinged on cylinder, both can guarantee that locating detent is connected to cylinder
On, but can with have relative motion between securing rod.4th, it is provided with bearing between handlebar and connecting rod, the circumferential movement of handlebar is not
Can be delivered on connecting rod, can meet the component being connected with connecting rod can only linearly moving demand.The all of part of the present invention all connects
It is connected on handlebar or cylinder, be not susceptible to lose.
Further, the length direction of described securing rod and the length direction of bar hole are consistent, can fully utilize locking
The length of bar.
Further, the length of described securing rod and the equal length of bar hole are it is ensured that alignment pin is in the arbitrary axle of securing rod
Can be locked to position.
Further, the side that described securing rod and alignment pin offset is provided with several scarce with alignment pin form fit
Mouthful, when such as securing rod and alignment pin offset, alignment pin is located in breach, and alignment pin is just difficult to slide with securing rod, and it is fixed to make
Position pin is limited in a fixed position by breach.
Brief description
Fig. 1 is the structural representation of hand locking device of the present invention.
Specific embodiment
Below by specific embodiment, the present invention is further detailed explanation:
Reference in Figure of description includes: handlebar 1, cylinder 2, securing rod 3, spring 4, locating detent 5, alignment pin
6th, bearing 7, bar hole 8, groove 9, connecting rod 10.
Embodiment is substantially as shown in Figure 1: a kind of hand locking device, including handlebar 1, cylinder 2, securing rod 3, spring
4 and in hook-shaped locating detent 5.Handlebar 1 is slidably connected in cylinder 2, and the side of handlebar 1 is provided with alignment pin 6, handlebar 1
On be arranged with bearing 7, one end that the inner ring of bearing 7 is located at outside cylinder 2 with handlebar 1 is fixedly connected, fixing on the outer ring of bearing 7
