In the range of the utility model protection.
As shown in Figs 1-4, a kind of strap brake castor according to the utility model embodiment, including trundle bracket 4, institute
The top for stating trundle bracket 4 is provided with rotatable connecting plate 1, and the lower part of the trundle bracket 4 is provided with caster axle 2, described
Wheel 3 is installed in caster axle 2, is evenly distributed in several location holes 5 on an end face of the wheel 3, on the trundle bracket 4
It is provided with brake gear, the brake gear includes positioning seat 6, and being equipped on the positioning seat 6 can be along the axial direction of the wheel 3
The pin shaft 7 of sliding, the pin shaft 7 are matched with any location hole 5.
In a specific embodiment of the utility model, the pin shaft 7 is provided with drawing away from one end of the location hole 5
Ring 8.
In a specific embodiment of the utility model, length of the pin shaft 7 in 3 axial direction of wheel is less than institute
State length of the positioning seat 6 in 3 axial direction of wheel.
In a specific embodiment of the utility model, the positioning seat 6 is arranged away from one end of the trundle bracket 4
There is limit plate, is provided with spring 9, the positioning between the end face of the location hole 5 on the limit plate and the pin shaft 7
The slot that the pull ring 8 can be supplied to pass through is provided on seat 6 and the limit plate.
In a specific embodiment of the utility model, the other end of the positioning seat 6 and 4 screw thread of trundle bracket
Connection.
In a specific embodiment of the utility model, it is provided on the trundle bracket 4 and matches with the positioning seat 6
The threaded hole of conjunction is provided with stop collar 10 corresponding to the threaded hole on the positioning seat 6.
In a specific embodiment of the utility model, the material of the trundle bracket 4 is aluminium alloy.
In order to facilitate the above-mentioned technical proposal for understanding the utility model, below by way of specifically used mode to the utility model
Above-mentioned technical proposal be described in detail.
Trundle bracket 4 is made of two pieces of support plates, is connected between support plate by top plate, and top plate and connecting plate 1 rotate
Connection, so that the 360 degree rotation of trundle bracket 4 can be realized.
Trundle bracket 4 is made of aluminum alloy material, has location hole 5 on wheel 3, can be with when needing to install brake gear
Threaded hole is opened up on trundle bracket 4 to be threadedly coupled with positioning seat 6.Restraining position ring block 10 is set on positioning seat 6, prevents positioning seat 6
Position is moved through when connecting with threaded hole, the length of positioning seat 6 is longer than the length of pin shaft 7, it is ensured that pin shaft 7 is fully accommodated in fixed
In the seat 6 of position, there is spring 9 between the limit plate on positioning seat 6 and pin shaft 7, to be also set up on pin shaft 7 convenient for pulling pin shaft 7
Pull ring 8, pull ring 8 pass through the end face of a Stud connection pin shaft 7, are provided on positioning seat 6 and limit plate for making pull ring 8
By slot.
With in use, carry out threaded hole on trundle bracket 4 first, corresponding location hole 5 is then made on wheel 3,
By the positioning seat 6 of brake gear on threaded hole, when wheel needs to walk, pull ring 8 is pulled, spring 9 is in compression
State, pin shaft 7 and wheel 3 are without interference.When wheel needs to brake, pull ring 8 is unclamped, spring 9 pushes pin shaft 7 mobile, pin
Its shaft end under the action of spring 9 of axis 7 puts in 5 the inside of location hole of wheel 3, and wheel 3 can not be walked, and plays braking action.
Also, after pulling pull ring 8 to disengage it from the slot on limit plate, pull ring 8 can be rotated, pull ring 8 drives pin shaft 7 to rotate, and is drawing
When ring 8 is perpendicular with slot on limit plate (limit plate at this position a settable shallow slot for stretching a part of pull ring 8
Enter, prevent pull ring 8 from rotating), pull ring 8 is unclamped, cannot be introduced at this time due to pull ring 8 in the slot of limit plate, it naturally also can not be along fixed
The slot sliding of position seat 6, and then move pin shaft 7 can not under the action of spring 9, so that pin shaft 7 and wheel 3 is always maintained at no interference
State.
In conclusion, using the brake gear of bolt mode, being saved by means of the above-mentioned technical proposal of the utility model
The space occupied, and it is simple and easy to operate.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
