Abstract

The utility model relates to a brake device of ice skates, which comprises a wheel carrier, a brake frame, a brake block, a torsion spring, etc., wherein, the brake frame is fixedly provided with the brake block. The utility model is characterized in that the brake frame and the brake block are correspondingly arranged on the wheel carrier; one end of the torsion spring is fixedly arranged on the wheel carrier; the other end of the torsion spring is fixedly arranged on the brake frame or the brake block; the brake block corresponding to the wheel flange of a roller is provided with a cambered surface; the cambered surface and the wheel flange of a roller at normal times are kept an interstice by the torsion spring; when the back end of the wheel carrier is pressed down and the brake block reaches to ground, the cambered surface can press the wheel flange of the roller at the same time, and the roller can be braked immediately.

Description

Stop device of ice skates

The utility model relates to a kind of ice skate brake gear, particularly a kind of roller skate brake gear.

General roller skate all sets firmly the brake block of a rubber system in the tail end roller outside, stop when the user desires to make ice skate, when halting, promptly mention tiptoe and make the outer brake block of heel prop up ground and the row brake, owing to the friction that only utilizes brake block and ground is braked, roller in fact also continues to roll, effect is not good, and because of the brake distance is longer, also can have little time once in a while very to end and the situation of collision.

The purpose of this utility model is: design a kind of novel ice skate brake gear, make brake shoes not only be butted on ground and can check roller, and then reach the effect that reduces the distance, stops rapidly and end.

To achieve these goals, this has novelly adopted following structure: a depression is established in the wheel carrier rear end; Brake is set up on the wheel carrier, and brake block is fixedly arranged on the brake frame and also is hubbed at wheel carrier relatively, and the corresponding roller wheel rim of brake block and be provided with a cambered surface; And establish one on the brake frame and extend block and can correspondence stretch into the depression part of wheel carrier and block; Torque spring one end is fixedly arranged on wheel carrier, and end is fixedly arranged on brake frame or the brake block in addition, makes the cambered surface normality of brake block keep a gap; And support and during ground when brake block, its cambered surface can be pressed from both sides simultaneously and be compeled the roller wheel rim and very end roller.

Adopt this structure can bring following advantage:

Wheel carrier tows distance when (1) shortening brake;

(2) shorten the very only time;

(3) thereby, the security of improve using.

Illustrate below in conjunction with example:

Graphic part:

Fig. 1 is this novel example side view.

Fig. 2 is this novel exploded view.

Fig. 3 is this novel cutaway view.

Fig. 4 is this novel enforcement illustration.

The figure number part:

(1) wheel carrier (2) brake frame

(3) brake block (4) torque spring

(11) depression (12) roller

(13) wheel shaft (14) fixing hole

(15) nut (21) side plate

(211) reach through hole (22) top board

(23) bolt (24) extends lug

(25) nut (31) cambered surface

(32) fixing hole (41) (42) bending end

As shown in Figure 1, 2, this novel wheel carrier (1), brake frame (2) brake block (3), torque spring members such as (4) of comprising, wherein:

Wheel carrier (1) is established a depression (11) in the rear end, and the wheel shaft (13) of the roller of its tail end (12) be pivoted simultaneously brake frame (2) and torque spring (4), and wheel shaft (13) end in addition is fixing with nut (15); Again, wheel carrier (1) rear also is provided with a fixing hole (14); Brake frame (2) is Qian type for sleeping in and tool two side plates (21), two side plates (21) front end is respectively established a reach through hole (211), in addition, connect two side plates (21) in end face with a top board (22), and the depression (11) of the corresponding wheel carrier of top board (22) front end (1) is stretched and is established one and extend lug (24), and top board (22) tool one nut (25) for bolt (23) break-through brake block (3) spiral shell solid; The end face (22) of brake frame (2) then sets firmly brake block (3) down and between two side plates (21); Brake block (3) corresponding roller (12) wheel rim and establish a cambered surface (31), and on the brake block (3) of fixing hole (25) position of correspondence brake frame (2), fixing hole (32) also is set; Torque spring (4) is tool two bending ends (41) (42) then.

Shown in Fig. 1,3, the brake embedded brake block of frame (2) (3) is also calmed in the last nut (25) of brake block (2) with bolt (23) break-through brake block (3) during combination; Wheel shaft (13) is then worn pivot torque spring (4), brake frame (2) and roller (12), and is locked by nut (15); The bending end (41) (42) of torque spring (4) is individually fixed in the fixing hole (32) of the fixing hole (14) of wheel carrier (1) and brake block (3); Again, the extension lug (24) of brake frame (2) then stretches in the depression (11) of wheel carrier (1).

When implementing (operation), shown in Fig. 3,4, the state when Fig. 3 is normality; Crack between the cambered surface (31) of brake block (3) and the wheel rim of roller (12) keep necessarily, at this moment, the power of torque spring (4) makes brake frame (2) and interior outer the opening of brake block (3) thereof, but be stuck in the depression (11) because of extending lug (24), so cambered surface (31) is kept from roller (12) wheel rim certain interval, and unlikely disengagement; And when brake, brake block (3) supports and ground, thereby goes up the top together with the frame (2) of braking, and extend lug (24) and stretch in the depression (11), and brake block (3) makes wheel carrier (1) immediately very end with its cambered surface (31) folder evil spirit roller (12).When no longer braking, the state that torque spring (4) will make brake frame (2) and brake block (3) reply Fig. 3.

Claims

1, a kind of ice skate brake device, comprise members such as wheel carrier, brake frame, brake block, torque spring, wherein brake and set firmly brake block in the frame, it is characterized in that: brake frame and brake block are to be hubbed at relatively on the wheel carrier, and torque spring one end is installed on the wheel carrier, the other end then is installed on the brake block, and the then corresponding roller wheel rim of brake block and be provided with a cambered surface, cambered surface and roller wheel keep a gap because of torque spring during because of normality.

2, ice skate brake gear according to claim 1, it is characterized in that: wherein a depression is established in the wheel carrier rear end, and brake frame then correspondence caves in and stretches and establish an extension lug that can stretch in the depression.

3, ice skate brake gear according to claim 1 is characterized in that: wherein the torque spring bending end that is fixedly arranged on brake block also can be fixed in the brake frame or be fixed in brake frame and brake block simultaneously.
