Abstract
The utility model relates to a trailer brake device. The trailer brake device comprises fixing plates which are symmetrically arranged at two sides of a frame, lug plates which are arranged on the fixing plates and are provided with lock pin holes, lock pins which are inserted on the lug plates through the lock pin holes and are provided with lock pin spring clamps, brake arms hinged on the fixing plates through rotating shafts, and a brake disc which is fixedly arranged on a trailer wheel, wherein lock pin springs which are clamped on the lock pin spring clamps are sleeved on the lock pins; the lower ends of the brake arms are connected with drawing wires through brake springs; and two brake holes corresponding to the lock pins are arranged on the brake disc. The trailer disclosed by the utility model can facilitate deadlock and opening even on a slope road when loaded, and rolling of the trailer is avoided.
Description
Technical field
The utility model relates to a kind of trailer brake device.
Background technology
The mode of present domestic low-carbon (LC) trip is more and more pursued, the use of trailer also begins slowly many, when stopping, needs need the equipment such as bicycle to brake, trailer mostly can be with thing, can slip car due to the ground injustice when the parking rest, and the people can not hold up car constantly, very inconveniently can not conveniently stop and start.
The utility model content
Technical problem to be solved in the utility model is to provide the locked brake equipment of a kind of trailer.The utility model adopts following technical scheme: the utility model comprises the adapter plate that is symmetricly set on vehicle frame both sides, be fixedly installed on the otic placode that is provided with lockpin hole on adapter plate, be plugged on the lock pin that is provided with the lockpin spring card on otic placode, be hinged at the brake control lever on adapter plate and be fixedly installed on brake disc on trailer wheel by rotating shaft by lockpin hole, described lockpin sleeve is equipped with the lockpin spring of holding on the lockpin spring card, described brake control lever lower end is connected with bracing wire by the brake spring, is provided with the brake hole corresponding with lock pin on described brake disc.
The elastic force that described lockpin spring and lockpin spring cartoon are crossed lockpin spring is embedded between two otic placodes.
The brake hole that arranges on described brake disc distributes in the form of a ring.
This novel good effect is as follows: use trailer of the present utility model, and can be easily locked and open, even can be very easily on the slope road when being loaded with weight locked and open, do not worry that car can slip car yet.
Description of drawings
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model locking process schematic diagram;
Accompanying drawing 3 is the utility model locking structure schematic diagram;
Accompanying drawing 4 be the utility model lock pin locked with the brake hole structural representation;
In the accompanying drawings: 1 adapter plate, 2 otic placodes, 3 lockpin holes, 4 lockpin spring cards, 5 lock pins, 6 brake control levers, 7 brake discs, 8 lockpin springs, 9 brake springs, 10 bracing wires, 11 brake holes, 12 rotating shafts, 13 vehicle frames, 14 trailer wheels.
The specific embodiment
as shown in accompanying drawing 1-4, the utility model comprises the adapter plate 1 that is symmetricly set on vehicle frame 13 both sides, be fixedly installed on the otic placode that is provided with lockpin hole 32 on adapter plate 1, be plugged on the lock pin that is provided with lockpin spring card 45 on otic placode 2 by lockpin hole 3, be hinged at the brake control lever 6 on adapter plate 1 and be fixedly installed on brake disc 7 on trailer wheel 14 by rotating shaft 12, described lock pin 5 is equipped with the lockpin spring 8 of holding on lockpin spring card 4, described brake control lever 6 lower ends are connected with bracing wire 10 by brake spring 9, be provided with the brake hole corresponding with lock pin 5 11 on described brake disc 7, described lockpin spring 8 and lockpin spring card 4 are embedded between two otic placodes 2 by the elastic force of lockpin spring 8, the brake hole 11 that arranges on described brake disc 7 distributes in the form of a ring, when needs stop, as accompanying drawing 1, 2, 3, shown in 4, tension is connected in the bracing wire 10 on handle, drive an end of brake control lever 6 by brake spring 9, make brake control lever 6 around rotating shaft 12 rotations, the other end promotes lock pin 5 and moves to brake disc 7 directions, overcome the elastic force of lockpin spring 8 in lock pin 5 moving process, when lock pin 5 moves to brake disc 7, as shown in Figure 2, just not during over against brake hole 11, lock pin 5 can not move on, bracing wire 10 can be shunk always, become large so be squeezed in the deformation meeting of brake spring 9 on brake disc 7 due to lock pin 5, the power of lock pin 5 extruding brake discs 7 can increase, do not worry directly handle being positioned at locking position, when trailer slips car, forward or backward, lock pin 5 can slip in a brake hole 11 nearest via lock pin 5 under the pulling force of brake spring 9 automatically, as accompanying drawing 3, shown in 4, complete the self-locking process, brake disc 7 and trailer wheel 14 are fixed together, this moment, trailer wheel 14 was by locked.When needing to start, with handlebar unlocked, bracing wire 10 resiliences, spring 9 potential energy that at this moment brake are released, and no longer affect lock pin 5, this moment, compressed lockpin spring 8 can back into original position with lock pin 5 under locking state, make lock pin 5 leave brake disc 7, from the interior extraction of brake hole 11, make trailer get back to free state, the utility model not only can be used on trailers, hand barrow, three-wheel vehicle equivalent-load instrument, can also be used for the self-propelled vehicle trailer.
Use trailer of the present utility model, can be easily locked and open, even can be very easily on the slope road when being loaded with weight locked and open, do not worry that car can slip car yet.
