Abstract
The utility model discloses a handle locking device. The handle locking device comprises a control rod, a base and a handle sleeve. A sliding groove for the control rod to be inserted into and poked to rotate is formed in the base. The control rod is sleeved with a casing pipe. A spring is arranged between the upper end of the casing pipe and the handle sleeve. A round protrusion is arranged at the lower end of the casing pipe, the outer diameter of the round protrusion is larger than the width of the sliding groove, and a round hole matched with the round protrusion is formed in the center of the sliding groove. A clamping pin is arranged on the outer wall of the control rod, and an L-shaped clamping groove is formed in the casing pipe, wherein the clamping pin can extend out of the L-shaped clamping groove and slide on the L-shaped clamping groove. Poking rotation of the control rod is limited through matching between the round protrusion and the round hole, and the control rod after being locked is stabilized through matching between the clamping pin and the L-shaped clamping groove; an overall improved structure is characterized in that only the casing pipe is arranged and broaching is carried out on an original sliding groove, so that transformation is convenient and easy; meanwhile, a locking mechanism guarantees safety and eliminates potential safety hazards.
Description
Technical field
The utility model relates to handle technical field, more specifically says a kind of handle lock locking apparatus.
Background technology
Handle, more common in the middle of our daily life, large gear lever to variator, little operating rod to master controller, conventional handle mainly comprises operating rod, pedestal and taper knob, on described pedestal, be provided with one and insert the also chute of switch for described operating rod, described taper knob is fixed on the upper free end of described operating rod in a spiral manner.
In actual production, often can accidentally encounter operating rod and carry out maloperation, serious also generation security incident, tracing it to its cause is also that conventional handle does not have lockable mechanism, so once not be in the mood for encountering and will cause maloperation, there is potential safety hazard.
Utility model content
The purpose of this utility model is to overcome the above defect of prior art, and a kind of simple in structure, handle lock locking apparatus that transformation is convenient, safe and reliable is provided.
In order to reach above object, the utility model is achieved through the following technical solutions: a kind of handle lock locking apparatus, comprise operating rod, pedestal and taper knob, on described pedestal, be provided with one and insert the also chute of switch for described operating rod, described taper knob is fixed on the upper free end of described operating rod in a spiral manner, it is characterized in that, the outer race of described operating rod is provided with a sleeve pipe, between the upper end of described sleeve pipe and described taper knob, be provided with a spring, the lower end of described sleeve pipe is provided with a boss, the external diameter of described boss is greater than the width of described chute, the center of described chute be provided with one with the suitable circular hole of described boss, on the outer wall of described operating rod, be provided with a bayonet lock, on described sleeve pipe, be provided with one and allow that described bayonet lock stretches out and " L " type draw-in groove of slippage thereon.
Limit operating rod switch by the cooperation of boss and circular hole, stablize the operating rod after locking by the cooperation of bayonet lock and " L " type draw-in groove again, make a general survey of improved structure also with regard to a sleeve pipe and reaming in former chute, so transformation is convenient, easy, lockable mechanism has ensured security simultaneously, has got rid of potential safety hazard.
As preferably, described " L " type draw-in groove be less than the distance of described bayonet lock to circular hole to the distance bottom of described boss bottom, the top of described " L " type draw-in groove to the distance bottom of described boss is greater than the distance of described bayonet lock to circular hole.
As preferably, the upper free end of sleeve pipe is outside equipped with one and controls cover, described in control that cover is outside has a flange of being affectedly bashful for staff.
Sleeve pipe need to be mentioned, and boss is separated from from circular hole, needs again rotation that bayonet lock locking in the middle of " L " type draw-in groove is lived, and this series of operation, just seems very simple afterwards by having set up to control to overlap.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model handle free state;
Fig. 2 is the structural representation of the utility model handle locking state.
In figure: 1-operating rod, 2-pedestal, 3-chute, 4-taper knob, 5-sleeve pipe, 6-spring, 7-circular hole, 8-boss, 9-bayonet lock, 10-" L " type draw-in groove, 11-controls cover.
Embodiment
Be easy to understand understanding in order to make technological means of the present utility model, creation characteristic and to reach object, further set forth the utility model below in conjunction with specific embodiment.
Embodiment: as depicted in figs. 1 and 2, a kind of handle lock locking apparatus, comprise operating rod 1, pedestal 2 and taper knob 4, on pedestal 2, be provided with one and insert the also chute 3 of switch for operating rod 1, taper knob 4 is fixed on the upper free end of operating rod 1 in a spiral manner, the outer race of operating rod 1 is provided with a sleeve pipe 5, and the upper free end of sleeve pipe 5 is outside equipped with one and controls cover 11, controls cover 11 outsides and has the flange of being affectedly bashful for staff.
Control between cover 11 upper end and taper knob 4 and be provided with a spring 6, the lower end of sleeve pipe 5 is provided with a boss 8, the external diameter of boss 8 is greater than the width of chute 3, the center of chute 3 be provided with one with the suitable circular hole 7 of boss 8, on the outer wall of operating rod 1, be provided with a bayonet lock 9, on sleeve pipe 5, be provided with one and allow that bayonet lock 9 stretches out and " L " type draw-in groove 10 of slippage thereon.
" L " type draw-in groove 10 be less than the distance of bayonet lock 9 to circular hole 7 to the distance bottom of boss 8 bottom, the top of " L " type draw-in groove 10 to the distance bottom of boss 8 is greater than the distance of bayonet lock 9 to circular hole 7.
Practical: as Fig. 1 when as shown in, sleeve pipe is up dialled, boss departs from circular hole, bayonet lock is stuck in the transverse groove of " L " type draw-in groove limited, control lever is unrestricted, freely switch in chute.
As Fig. 2 when as shown in, bayonet lock rotates the transverse groove of disengaging " L " type draw-in groove and forwards cannelure to, and sleeve pipe is moved down by spring reset, and boss snaps in circular hole, because the external diameter of circular hole is greater than the width (being learnt by boss) of chute, sleeve pipe has limited the switch of operating rod.
