Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
It please refers to shown in Fig. 1 and Fig. 2, wherein Fig. 1 is the structural diagram of the present invention, and Fig. 2 is brake pedal of the invention
Structural schematic diagram.
A kind of strap brake structure provided by the invention rises castor 1, including castor 1 and the top for being connected to 1 upper end of castor
High device 2, castor 1 include wheel carrier 11 and wheel 12, and wheel 12 is connected on wheel carrier 11 by shaft 13, coaxially connected in shaft 13
Stopping gear 14, stopping gear 14 and the circumferentially fixed realization of shaft 13 rotate synchronously, scalable setting retainer 10 on wheel carrier 11,
10 end of retainer is equipped with the latch 100 being adapted to stopping gear 14, and retainer 10 is connect with brake pedal 15.
Meanwhile brake pedal 15 is connect by mandril 16 with the pedal 21 of rising for rising device 2,16 one end of mandril is fixed on top
It is foot-operated when rising pedal 21 in the other end and the movable telescopic hole for being connected to 15 upper end of brake pedal on high pedal 21, it rises
Pedal 21 drives mandril 16 to push brake pedal 15, so can be with by rising that the control of pedal 21 rises during device 2 is risen
When synchronizing and carry out brake fixation to castor 1, wheel 12 during rising is avoided to roll, and rising device 2 and be in retracted state,
It can be controlled separately brake pedal 15 to brake to wheel 12, control more diversified.
In a kind of preferred embodiment of above-mentioned brake pedal 15, brake pedal 15 includes foot pedal 151 and passes through
The guide ring 152 that connecting rod is connected to 151 lower end of foot pedal forms, and guide ring 152 is socketed on the sleeve 22 for rising device 2, sleeve
22 are equipped with supporting rib 220, and 151 end of foot pedal is articulated on supporting rib 220, when brake, foot-treadle 151, and foot pedal
151 with the pivoting point of supporting rib 220 be support, drives guide ring 152 to move downward along 22 direction of sleeve by connecting rod, guide ring
152 avoid brake pedal 15 from shifting the active force of retainer 10 with the cooperation of sleeve 22, increase integrally-built stabilization
Property.
Meanwhile 151 middle part of foot pedal is annular in shape and is set on sleeve 22, connecting rod quantity is 2 and is symmetricly set on foot
152 two sides of pedal 151 and guide ring, symmetrical structure make being more uniformly stressed and stablizing for guide ring 152, avoid it is unilateral by
The problem of power, guide ring 152 and sleeve 22 collide with mutually.
In conjunction with shown in Fig. 3 and Fig. 4, Fig. 3 is retainer retracted mode schematic diagram of the present invention, and Fig. 4 is that retainer of the present invention is stretched
Do well schematic diagram, and in a kind of preferred embodiment of above-mentioned retainer 10, retainer 10 includes connecting with brake pedal 15
Compression bar 101, the lock piece 102 and the reset spring 103 that is connect with lock piece 102 that are rotatably connected in 101 lower end of compression bar,
Reset spring 103 and 102 coaxial inner conductor of lock piece are arranged and are located at 102 bottom end of lock piece, and wheel carrier 11 is equipped with through-hole 110, pressure
Outside bar 101 and lock piece 102 and the scalable setting of wheel carrier 11 is in through-hole 110, meanwhile, 101 outer edge surface of compression bar is equipped with guiding
Wire casing 1010, the terminal surface of guiding wire casing 1010 are inclined-plane, are equipped in the through-hole 110 of wheel carrier 11 and are oriented to what wire casing 1010 was adapted to
Guide protrusions 1100, the interval setting of guiding wire casing 1010, compression bar 101 and lock piece 102 be equipped at connecting pin it is mutual be adapted and
Spaced inclined-plane tooth 1000 and sliding slot 1001, latch 100 are set to 102 bottom end of lock piece.
When brake pedal 15 presses 101 top of moulded rod, apply a downward pressure to compression bar 101, compression bar 101 is along guiding
1010 direction of sliding slot movement compressing lock piece 102 moves downward, when guiding wire casing 1010 and the guide protrusions 1100 of compression bar 101
When engagement place is detached from, the inclined-plane tooth 1000 on 101 head of compression bar and 1001 contact position of sliding slot of lock piece 102 generate radial force and force
Lock piece 102 is rotated and is moved downward, and retainer 10 is in stretching state, and latch 100 is engaged with stopping gear 14, and wheel 12 is stopped
Vehicle；When descending moulded rod 101 again, the inclined-plane tooth 1000 on 101 head of compression bar is separated with 1001 inclined-plane of sliding slot of lock piece 102,
Lock piece 102 is rotated by radial force, and guiding wire casing 1010 is overlapped with the engagement place of guide protrusions 1100, and lock piece 102 is resetting
It is retracted under the action of spring 103, retainer 10 is in retracted mode, and latch 100 and stopping gear 14 separate, and shaft 13 is restored to turn
Dynamic, brake is cancelled.In this way, can still be stepped on by foot after by rising the control brake of pedal 21 and once rise the control brake of pedal 21
The cancellation of vehicle, three functions of rising that device 2 is risen, the brake of castor 1 and cancellation are braked can be controlled by rising pedal 21, play simplification
The effect of operation, meanwhile, the cooperation of compression bar 101, lock piece 102 and wheel carrier 11 carries lock function, and it is single to eliminate traditional castor 1
The location structure being solely arranged, simplifies structure.
Meanwhile the quantity of retainer 10 and stopping gear 14 is 2 and is symmetricly set on wheel body two sides, such stop tooth
The uniform force of wheel 14 and shaft 13, structural stability are improved.
To further strengthen structural stability of the castor 1 under braking state, what lock piece 102 and wheel carrier 11 were equipped with
The pin hole 1010 being laterally arranged, it is scalable in pin hole 1010 to be provided with pin 1011, it is right between pin hole 1010 under braking state
Together, pin 1011 passes through pin hole 1010 and connects lock piece 102 and wheel carrier 11, reduces retainer 10 inside and answers with wheel carrier 11
Power, and then improve the structural strength of wheel 12.
The castor 1 of rising of the strap brake structure is connected in 1 upper end of castor and rises device 2, and the object for rising device 2 and upper end connects
It connects, for adjusting height, wherein castor 1 includes wheel carrier 11, is connected to wheel 12 on wheel carrier 11 by shaft 13, in shaft 13
The end of coaxially connected stopping gear 14, scalable setting retainer 10 on wheel carrier 11, retainer 10 is equipped with and stopping gear 14
The latch 100 of adaptation, retainer 10 are connect with brake pedal 15, and when brake, user's foot touches on the brake pedal 15, brake pedal 15
10 downlink of retainer is driven, the latch 100 of 10 end of retainer is engaged with stopping gear 14, and shaft 13 is made to lose rotation freely
Degree, and then wheel 12 is prevented to rotate, braking effect is played, compared to the brake modes of existing padded formula, strap brake structure of the present invention
The brake structure for rising castor 1 it is simpler reliable, convenient for operation.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
