Description
Technical field
The utility model relates to a kind of castor, is specifically related to a kind of castor of belt brake.
Background technology
Castor generally comprises and is connected to Connection Block bottom furniture or apparatus, be connected to bracing frame below Connection Block by the first axis of rotation vertically arranged, the roller be connected to by the second axis of rotation arranged in the horizontal direction on bracing frame.Castor, generally with braking mechanism, when furniture or apparatus are moved to a certain assigned address, starts braking mechanism and is fixedly made it by roller to roll.The castor of belt brake of the prior art, the structure of general employing brake facing, roller is generally quality of rubber materials, by brake facing pinch rollers, friction force between brake facing and roller is braked, but the braking mechanism of this structure exists certain drawback, the friction force namely between brake facing and roller is inadequate, causes brake firm not.
Chinese patent application publication No. CN104108283A, Shen Qing Publication day is the castor that the patent of invention on October 22nd, 2014 discloses a kind of belt brake, comprise Connection Block, the bracing frame below Connection Block is connected to by the axis of rotation vertically arranged, the roller on bracing frame is connected to by the axis of rotation arranged in the horizontal direction, bracing frame is provided with the braking mechanism that restriction roller rotates, braking mechanism comprises and is connected on bracing frame by the first axis of rotation and has elastomeric brake facing, the pedal be connected on bracing frame and with brake facing is connected to by the second axis of rotation, brake facing is provided with the projection of at least one pair of, often pair of protruding front and back are oppositely arranged and all have an inclined-plane, often pair of protruding two inclined-planes are all arranged on protruding outside and all extend to direction close to each other, braking mechanism also comprises and to be fixedly connected with Connection Block and to offer the rotating disk of multiple draw-in groove, be arranged on the fixture block be connected separatably with draw-in groove on brake facing.
Although this device is by improve the braking effect of castor to the transformation of brake structure, but its brake structure parts are numerous, it is all very inconvenient to install and keep in repair, and along with castor period of service elongated, the PU material of roller outside is inevitable more and more thinner, and the brake facing in existing brake system can only move in distance to a declared goal, the distance between roller and brake facing exceeds its braking effect of moving range and must have a greatly reduced quality, and finally can only change roller to reach best braking effect.
Summary of the invention
The purpose of this utility model is the defect and the deficiency that overcome existing technology, provides that a kind of structure is simple, braking effect good, the castor of the belt brake of long service life.
For realizing above object, technical solution of the present utility model is: a kind of castor of belt brake, comprise Connection Block, bracing frame and roller, support frame as described above is flexibly connected with Connection Block by rotating shaft, described roller is fixed on the inside of bracing frame by screw rod, support frame as described above is provided with the braking mechanism that restriction roller rotates, described braking mechanism comprises brake facing and pedal, it is characterized in that: described brake facing and pedal are all sleeved on screw rod, pedal is that S. A. rotates with screw rod, brake facing and pedal are 90 ° of angles, brake facing is provided with spacing salient point and positive stop hook, spacing salient point and positive stop hook lay respectively at the both sides up and down of pedal.
Described pedal is respectively arranged with arc surface and lower arc surface, the distance between described upper arc surface and spacing salient point is less than the arc length of arc surface, and the distance between described lower arc surface and positive stop hook is less than the arc length of lower arc surface.
Described brake facing extends the top of roller by the bayonet socket be positioned on bracing frame.
The utility model compared to existing technology, has following advantage:
1, simple, the flexible operation of the utility model structure, the accurate brake that can realize brake facing is coordinated with exquisite between spacing salient point, positive stop hook by pedal, and due to the ingehious design of spacing salient point, the cooperation of too many part is not needed when making brake facing rest on normal danger, equipment failure rate is low, long service life.
2, the position and the arc length that go up arc surface and lower arc surface in the utility model design, and make the brake facing in this device have larger moving range, even if rolling wheel wear, brake facing also can reach best braking effect, thus extends the service life of castor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
In figure: Connection Block 1, bracing frame 2, roller 3, rotating shaft 4, screw rod 5, braking mechanism 6, brake facing 7, pedal 8, spacing salient point 9, positive stop hook 10, upper arc surface 11, lower arc surface 12, bayonet socket 13.
Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and with detailed description of the invention, the utility model to be described in further detail.
See Fig. 1-Fig. 2, a kind of castor of belt brake, comprise Connection Block 1, bracing frame 2 and roller 3, support frame as described above 2 is flexibly connected with Connection Block 1 by rotating shaft 4, described roller 3 is fixed on the inside of bracing frame 2 by screw rod 5, support frame as described above 2 is provided with the braking mechanism 6 that restriction roller 3 rotates, described braking mechanism 6 comprises brake facing 7 and pedal 8, described brake facing 7 and pedal 8 are all sleeved on screw rod 5, the left end of pedal 8 is brake pedal, right-hand member is for releasing the pedal, pedal 8 with screw rod 5 for S. A. rotate, brake facing 7 and pedal 8 are in 90 ° of angles, brake facing 7 extends the top of roller 3 by the bayonet socket 13 be positioned on bracing frame 2, brake facing 7 is provided with spacing salient point 9 and positive stop hook 10, spacing salient point 9 be positioned at pedal 8 directly over, positive stop hook 10 is positioned at immediately below pedal 8.
Described pedal 8 is respectively arranged with arc surface 11 and lower arc surface 12, the distance between described upper arc surface 11 and spacing salient point 9 is less than the arc length of arc surface 11, and the distance between described lower arc surface 12 and positive stop hook 10 is less than the arc length of lower arc surface 12.Such design can make the upper arc surface 11 of pedal 8 can have the contact of longer distance with spacing salient point 9, and then the lower arc surface 12 of pedal 8 also can have the contact of longer distance with positive stop hook 10, be exactly lower that brake facing 7 can be sunk its final order, braking effect can not be affected because of the wearing and tearing of roller 3.
When the castor in the utility model needs drag, tramp with one's feet and step on the brake pedal of plate 8 left end, brake pedal sinks, drive lower arc surface 12 turning clockwise, lower arc surface 12 can be oppressed positive stop hook 10 and be sunk in the process of turning clockwise, and then drive whole brake facing 7 to decline, in decline process, spacing salient point 9 can contact with upper arc surface 11, and with upper arc surface 11 friction of rolling, after brake facing 7 contacts with roller 3, brake facing 7 can stop declining, and rely on spacing salient point 9, with the friction force of upper arc surface 11, castor is rested on braking state, now roller 3 cannot rotate, reach brake object, and due to spacing salient point 9 and upper arc surface 11 are Structure deformation, therefore go up arc surface 11 not disengage with spacing salient point 9, brake facing 7 is with regard to the leeway that declines in addition, when castor needs release brake, only need to tramp with one's feet to step on releasing the pedal of plate 8 right-hand member, upper arc surface 11 turns round, can by spacing salient point 9 jack-up, and then drive whole brake facing 7 to rise, when upper arc surface 11 revolution puts in place, brake facing 7 also can get back to initial position, and now roller 3 can freely be advanced.
