Background
The wheelchair is a common medical apparatus, and is commonly used for various patients who are inconvenient to move, generally, the wheelchair is divided into an electric wheelchair and a common wheelchair, the electric wheelchair controls the movement of the wheelchair through a motor, and the common wheelchair is generally provided with a side tire manually pushed by a user or a wheelchair assisted by a person behind the side tire.
Comparatively common ordinary wheelchair in the market at present, its brake mostly all designs in the handle below that pushes away the wheelchair in the rear, each brake lever of controlling comes to control the tire and brakes, and the user of sitting on the wheelchair wants to brake, can only brake through the tire side tire of manual grasping the wheelchair, when meetting special cases, the unable timely control wheelchair of rear auxiliary personnel is braked, and the not enough unable braking wheelchair of can't forcing of user's strength, will make among the user's entering more dangerous condition.
Therefore, a brake design is needed that allows a user to easily brake while sitting in a wheelchair.
SUMMERY OF THE UTILITY MODEL
In view of the above problems in the prior art, it is an object of the present invention to provide a wheelchair brake linkage.
In order to solve the above problems, the present invention adopts the following technical solutions.
The utility model provides a wheelchair brake aggregate unit, includes brake pivot, brake lever and braked wheel, the brake pivot includes base, pivot dish and fixing base, and the pivot dish sets up on brake base, and the base is equipped with the rotation axis, and the pivot dish is equipped with the shaft hole that corresponds with the rotation axis, and the pivot dish is equipped with at least one brake cable tie point, and brake cable tie point and shaft hole do not coincide, and the fixing base is fixed pivot dish on the base, brake lever and braked wheel be connected to the brake cable tie point respectively through the brake cable.
The hub disc is circular, and the brake cable connecting points are arranged around the center of the hub disc symmetrically.
And 1-4 brake cable connection points are arranged on the pivot disc.
The side of the hinge plate is provided with a brake cable groove, the brake cable groove has two layers, one layer of the brake cable groove is used for placing the brake cable connected with the brake handle, and the other layer of the brake cable groove is used for placing the brake cable connected with the brake wheel.
The brake device is characterized in that the number of the brake handles and the number of the brake wheels are two, the brake cables of the two brake handles are connected to a group of brake cable connection points which are symmetrical to each other, and the brake cables of the two brake wheels are connected to another group of brake cable connection points which are symmetrical to each other.
Compared with the prior art, the wheelchair can give consideration to the fact that a user can brake easily when the wheelchair is used alone or accompanying personnel cannot brake in time in an emergency, and the user can sit on the wheelchair to brake through the front brake grip, so that the user is not in a dangerous situation.
Drawings
FIG. 1 is a schematic view of a brake hinge;
FIG. 2 is a schematic structural view of the present invention;
in the figure: 1. a base; 2. a hinge plate; 3. a fixed seat; 4. a front brake lever; 5. a rear brake lever; 6, front brake cable; 7. a rear brake cable; 8. brake wheel brake cable.
Detailed Description
The utility model is further described with reference to specific examples.
Example 1
As shown in fig. 1, the structure of brake pivot divide into base 1, pivot dish 2 and fixing base 3, base 1 is square, the symmetry both sides are equipped with four recesses that supply the brake cable to get into in total, central point puts and is equipped with an axle, pivot dish 2 is installed to base 1 on, its central point puts and is equipped with the shaft hole and installs in the axle center, make pivot dish 2 can freely rotate in base 1, and pivot dish is equipped with two sets of brake cable tie points of four symmetries altogether, fixing base 3 is the square the same with the base in size, fix on base 1 through four bolts, its bolt fastening point staggers with four apex angles of base 1, the holistic fixed of brake pivot can not be influenced in this kind of design.
As shown in fig. 2, preceding brake lever 4 and back brake lever 5 are connected to the brake hub through the brake cable, two brake lever brake cables get into base 1 from the recess of a set of symmetry in, then install respectively on the brake cable tie point of a set of symmetry, two brake wheel brake cables are fixed on the brake cable tie point of another set of symmetry through remaining two recesses simultaneously, the side of hub dish 2 is equipped with two brake cable recesses, the brake cable of connecting the brake lever is placed to one of them recess, the brake cable of connecting the brake wheel is placed to another recess, overlap between the brake cable can be avoided in this kind of design, reduce the loss that friction brought.
During the in-service use, any one brake lever in preceding brake lever 4 and the back brake lever 5 of gripping all can drive hub disc 2 rotatory, and the direction of rotation is the same, can tighten up the braked wheel brake cable simultaneously, plays the braking action. Therefore, the design of the utility model can change the brake originally arranged at the handrail of the cart behind the frame into the position, and can respectively control the two brake wheels to brake simultaneously, thereby effectively leading the user to brake actively and effectively when meeting emergency.
Example 2
The appearance of the brake hub is the same as that of the embodiment 1, the difference is that three brake cable connection points are arranged on the hub disc 2, only one brake cable connection point of one brake lever is reserved, and other two brake cable connection points are still connected to the brake wheel.
Example 3
The appearance of its brake pivot is the same with embodiment 1, and the difference is that brake cable tie point on the pivot dish 2 is only one, and arbitrary quantity brake lever and braked wheel all can be connected to the brake cable tie point through the brake cable, and pivot dish 2 normally rotates when gripping the brake lever, drives all brake cables that are connected to the brake cable tie point and moves together, can normally realize the brake function. The side groove part of the hub plate 2 can distinguish the brake cable of the brake handle and the brake wheel, and can also be provided with only one groove, and the brake cable is intensively placed.
The above description is only an exemplary embodiment of the present invention, and is not intended to limit the scope of the present invention. It will be appreciated by those skilled in the art that changes may be made in this embodiment without departing from the principles and spirit of the utility model, the scope of which is defined by the appended claims.
