Description
Technical field
The utility model belongs to escape, rock-climbing, and rescue field, is specifically related to a kind of manual high-rise descent control device of bidirectional locking.
Background technology
At present, along with the raising of people's living standard, various building is more and more higher, and fire also takes place frequently constantly, live in the threat that the people's life security on high building is subject to also more and more serious, and existing high-rise escape apparatus, due to all serious shortcomings, as grasped complexity, is difficult to self-locking or manually locked on market, with high costs etc. is that this type of mechanism can not get promoting on a large scale, based on this background, invention is a kind of simple to operate, and it is particularly urgent that the laborsaving and reliable high-rise descent control device of locking shows.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of manual high-rise descent control device of bidirectional locking, realizes cost of manufacture cheap under the prerequisite of safe rescue, small and exquisite portable, simple to operate, safe and reliable, automatic locking, manual governing, rescues etc. repeatedly.
In order to achieve the above object, the utility model comprises the first joystick and the housing with the second joystick, the rotation roller that two are tied with band rope is vertically provided with in housing, be provided with between two rotation rollers can with the friction pulley of two rotation roller close contacts, band rope all contacts with friction pulley with two rotation rollers, first joystick stretches in housing, and be provided with the friction pulley be connected with friction pulley and press from both sides, first joystick can carry dynamic friction wheel transverse shifting secretly by friction pulley, side in housing is provided with and the gripper shoe coordinated after friction pulley transverse shifting.
Described rotation roller comprises the first rotation roller second rotation roller, is provided with straight pin below the first rotation roller;
Described band rope enters from housing tip and contacts clockwise with the first rotation roller, and extend to the second rotation roller from the gap between the first rotation roller and gripper shoe, and contact with friction pulley, band rope extands rearward to straight pin by the second rotation roller change side, the first rotation roller is extanded rearward to again by straight pin change side, wrapped anti-clockwise first rotation roller, and draw from housing bottom after changing direction by the first rotation roller.
Described gripper shoe offers the recess that shape line outside with friction pulley is consistent.
The edge of the opposite side in described housing is provided with support gusset.
Compared with prior art, the utility model is by human bady gravitational effect, the band rope tightened can have a power left to friction pulley, make friction pulley to left movement, embed between upper and lower two rotation rollers, thus be clamped around the part band rope between rotation roller and friction pulley, achieve auto-lock function, by the power of clutching of joystick, friction pulley is moved right a bit of distance, remove because friction pulley embeds the self-locking state formed between rotation roller, appropriateness unclamps band rope, control downhill race velocity interpolation steadily to glide, when being applied to the power of clutching on joystick and increasing to a certain degree, friction roller moves right and coordinates grip tape rope with gripper shoe, thus lockable mechanism, stop gliding, the utility model can under the effect of human body self gravitation automatic self-locking, simultaneously also lockable when clutching joystick, thus ensure that due to overstretched cause out of control to this device or control is excessive time personnel safety, and do not need when realizing locking to expend muscle power etc., thus improve security reliability, be easy to carry operation.
Further, the recess that the utility model gripper shoe is offered can make the contact area of band rope and gripper shoe increase, thus reaches the effect of increasing friction force.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
See Fig. 1, the utility model comprises the first joystick 5 and the housing 9 with the second joystick 6, the rotation roller 1 that two are tied with band rope 10 is vertically provided with in housing 9, be provided with between two rotation rollers 1 can with the friction pulley 2 of two rotation roller 1 close contacts, band rope 10 all contacts with friction pulley 2 with two rotation rollers 1, first joystick 5 stretches in housing 9, and be provided with the friction pulley be connected with friction pulley 2 and press from both sides 3, first joystick 5 can press from both sides 3 drive friction pulley 2 transverse shiftings by friction pulley, the gripper shoe 7 that side in housing 9 coordinates after being provided with and laterally moving to right with friction pulley 2, gripper shoe 7 offers the recess 11 consistent with friction pulley 2 outside shape line, the edge of the opposite side in housing 9 is provided with and supports gusset 8, rotation roller 1 comprises the first rotation roller 1-1 and the second rotation roller 1-2, is provided with straight pin 4 below the first rotation roller 1-1, band rope 10 enters from housing tip and contacts with the first rotation roller 1-1, the second rotation roller 1-2 is extended to from the gap between the first rotation roller 1-1 and gripper shoe 7, and contact with friction pulley 2, band rope 10 extands rearward to straight pin by the second rotation roller 1-2 change side, extand rearward to the first rotation roller 1-1 in straight pin change side, draw bottom housing 10 at wrapped anti-clockwise first rotation roller 1-1 and after changing direction.
The utility model drives friction pulley to press from both sides 3 by adjustment first joystick 5, makes friction pulley 2 realize moving back and forth reaching bidirectional locking, by the extruding of friction pulley 2 with gripper shoe 7, and the frictional force of accommodation zone rope, thus realize controlling gliding speed; When gliding, if do not controlled the first joystick 5, due to Action of Gravity Field, the band rope tightened can take turns to reciprocating sliding friction the power that 2 have a left direction, make friction pulley to left movement, embed between upper and lower two rotation rollers 1, thus be clamped around the part band rope between rotation roller 1 and friction pulley 2, achieve auto-lock function; When the first joystick 5 appropriateness being clutched, friction pulley 2 is moved right a bit of distance, remove because friction pulley 2 embeds the self-locking state formed between two rotation rollers 1, appropriateness unclamps band rope, realizes steadily gliding; When afterburning first joystick 5 further, then rope band is clamped by friction pulley 2 and gripper shoe 7, increases the frictional force that rope band slides, thus reaches to slow down and glide and the effect of friction locking.
The utility model breaks through traditional locks rope not bery firmly shortcoming, realize handle dibit locking, namely handle all can the locking of implement device when loosening and clutch, possesses safe rescue, be easy to carry, handling good, the features such as low cost of manufacture, economic benefit, social benefit are remarkable, have broad application prospects.
