Reliability is low, easily releases, and part is exposed, exquisiteness not attractive in appearance enough.Due to needing to pull, pin steps on underaction, often
Operated with hand, it is unhygienic also inconvenient.
Brake apparatus of the prior art has to be improved regarding to the issue above, but generally all structures are relative complex.As specially
Profit number is a kind of 201420425771.0 case and bag brake caster, passes through the gear member braked in biting teeth and castor on joggle piece
Engagement, quick and stabilization can play a part of brake, but need again the another gear installed on brake joggle piece and castor
Part, considerably increases the structure complexity of brake gear.
Utility model content
The purpose of this utility model be solve in the prior art technical problem there is provided one kind it is reasonable in design, it is simple in construction, behaviour
Make the case and bag road wheel easily with brake apparatus.
To achieve the above object, the technical solution adopted in the utility model is：
A kind of case and bag road wheel with brake apparatus, including support and the roller installed in support both sides, support with
Brake gear is provided between roller, described brake gear includes mounting groove, push type reciprocating lifting mechanism and brake shoes；
Push type reciprocating lifting mechanism is installed in the mounting groove, the push type reciprocating lifting mechanism from top to bottom according to
It is secondary including runner, cam, spring, fixed block, the mounting groove inwall is provided with the vertical idler coordinated with runner, the fixed block
Fixed by pin with installing trench bottom, the runner is provided with brake shoes, and both are fixed by pin；
The both sides of the brake shoes are provided with the braking internal tooth coordinated with brake dop provided with brake dop, the roller inner side
Circle.
The contact surface of the brake dop and braking ring gear, the radian one of the contact surface and the teeth groove of braking ring gear
Cause.
The mounting groove is horizontal by 45 °.
The brake shoes inwall is provided with neck, and the mounting groove is provided with the fixture block coordinated with neck.
The push type reciprocating lifting mechanism is additionally provided with spring fixing groove, is installed between spring and fixed block.
Compared with prior art, the beneficial effects of the utility model are：
A kind of case and bag road wheel with brake apparatus that the utility model is provided, will directly set brake on brake shoes
Dop, by the cooperation of brake dop and braking ring gear, reaches the effect of braking, design is closed by the way of pin touches on the brake block
Reason, simple in construction, simple operation.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
As Figure 1-4, a kind of case and bag road wheel with brake apparatus that the utility model is related to, including support (1)
And the roller (2) installed in support (1) both sides, brake gear is provided between support (1) and roller (2), brake gear includes
Mounting groove (8), push type reciprocating lifting mechanism (7) and brake shoes (3)；
Push type reciprocating lifting mechanism (7) is installed in mounting groove (8), as shown in figure 4, push type reciprocating lifting mechanism
(7) similar similar to the telescoping mechanism of ball pen, it from top to bottom includes runner (71), cam (72), spring (73), bullet successively
Spring (73) fixed groove (74), fixed block (75), spring (73) fixed groove (74) can be with so that the location and installation of spring (73)
It is more solid and reliable.Mounting groove (8) inwall is provided with the vertical idler coordinated with runner (71), and fixed block (75) passes through pin and peace
Tankage (8) bottom is fixed, and runner (71) is provided with brake shoes (3), and both are fixed by pin；Pass through push type reciprocating elevator
Structure (7) realizes the flexible of brake shoes (3).
The both sides of brake shoes (3) are provided with the braking coordinated with brake dop (4) provided with brake dop (4), roller (2) inner side
