Abstract
The invention discloses a stand roller braking device for a movable stand. The device comprises a roller arranged at the bottom of the stand, wherein a square tube is arranged on the side wall of a stand base in a movable mode and positioned above the roller; a braking disc is fixedly arranged on the lower side of the square tube and positioned on the outer side of the roller; one end of the square tube is connected with a screw rod through threads; the screw rod is arranged in a screw rod combining sleeve in the movable mode; the outer end of the screw rod stretches out of the screw rod combining sleeve; the screw rod combining sleeve is fixedly arranged on the stand; and the outer end of the screw rod is provided with a driving device for driving the screw rod to rotate. The stand roller braking device is arranged on the movable stand base, and the braking disc below the square tube is driven to move to the roller by rotating the screw rod, so that the braking disc and the roller are tightly clamped, and the movable stand base does not generate displacement; and the device has high braking performance and durability and a simple structure and is convenient to use.
Description
Technical field
The present invention relates to the brake device of rolling wheels for stand in the movable stand.
Background technology
Now athletics sports are not only more and more higher for the requirement of sport equipment, also progressively improving for the requirement of movable stand, and except will merging mutually with venue integral body, flexible in the time of also will guaranteeing its telescopic slide.When needs use movable stand, by the staff movable stand is pulled out to the required number of plies; The shortcoming of at present used movable stand is: the bottom roller of movable stand does not have braking device, causes when using easily freely to be shifted, and has potential safety hazard.
Summary of the invention
The technical problem of solution required for the present invention is: a kind of brake device of rolling wheels for stand of freely being shifted of not occuring when movable stand is used is provided.
For addressing the above problem, the technical solution used in the present invention is: described brake device of rolling wheels for stand comprises: the roller that is arranged on arranged at bottom of stand, sidewall at the grandstand base is movably set with square tube, square tube is positioned at the top of roller, the downside of square tube is fixedly installed brake disc, brake disc is positioned at the outside of roller, one end of square tube is connected with screw mandrel by screw thread, screw mandrel is movably arranged in screw mandrel and the cover and stretch out outside screw mandrel and the cover screw mandrel outer end, screw mandrel and cover are fixedly mounted on the arranged at bottom of stand, and the screw mandrel outer end also is provided with and drives the drive unit that screw mandrel rotates.
The structure that arranges between described square tube and the grandstand sidewall is: be provided with rectangular groove in square tube, position corresponding with rectangular groove on the grandstand base side wall is provided with lead, and lead extend in the rectangular groove.
Above-mentioned square tube and the syndeton between the screw mandrel are: the internal thread of the external screw thread of screw mandrel and square tube end is in mating connection.
The outer end portion of described screw mandrel is arranged in the handle hole of screw mandrel overcoat, screw mandrel overcoat and screw mandrel and cover are fixedly connected, triangular in shape or the rectangle of the cross section of screw mandrel outer end, described drive unit is handle, the cross section that shakes the hole on the handle is also triangular in shape or rectangle correspondingly.
The invention has the beneficial effects as follows: be provided with described brake device of rolling wheels for stand at movable stand, the brake disc way roller that drives the square tube below by rotary screw rod moves, brake disc and roller are tightly blocked, movable stand is not subjected to displacement, braking quality is good, durability is strong, and is simple in structure, easy to use.
Description of drawings
Below in conjunction with accompanying drawing technical solutions according to the invention are described in further detail.
Fig. 1 is the structural representation of brake device of rolling wheels for stand of the present invention.
The specific embodiment
Referring to shown in Figure 1, brake device of rolling wheels for stand of the present invention, comprise: the roller 1 that is arranged on grandstand base 10 bottoms, sidewall at grandstand base 10 is movably set with square tube 3, square tube 3 is positioned at the top of roller 1, the downside of square tube 3 is fixedly installed brake disc 2, brake disc 2 is positioned at the outside of roller 1, one end of square tube 3 is provided with internal thread, screw mandrel 4 is connected with internal thread on the square tube 3 by the external screw thread on the screw mandrel, screw mandrel 4 is movably arranged on screw mandrel and overlaps in 6, and screw mandrel 4 outer ends are stretched out screw mandrel and are overlapped outside 6, and screw mandrel also overlaps 6 and is fixedly mounted on the grandstand base 10, and the screw mandrel outer end also is provided with and drives the drive unit that screw mandrel rotates.In the present embodiment, the structure that arranges between described square tube 3 and grandstand base 10 sidewalls is: be provided with a pair of rectangular groove 31 in square tube 3, position corresponding with rectangular groove 31 on grandstand base 10 sidewalls is provided with lead 9, lead 9 extend in the rectangular groove 31, and such structure can make square tube 3 slide along lead 9 better.In the present embodiment, the outer end portion of screw mandrel 4 is arranged in the handle hole 7 of screw mandrel overcoat 8, screw mandrel overcoat 8 is with screw mandrel and overlap 6 and be fixedly connected, triangular in shape or the rectangle of the cross section of screw mandrel outer end, drive unit described in the present embodiment is handle 11, the cross section that shakes the hole on the handle 11 is also triangular in shape or rectangle correspondingly, can make like this handle 11 be defined as movable wire bar 4 and rotate.In actual use, described drive unit can also adopt stepper motor or motor to drive screw mandrel 4 by drive disk assembly and rotate, and these change the protection domain that all should belong to this patent.
When needs use movable stand, by the staff movable stand is pulled out to the required number of plies, then handle 11 is inserted handle hole 7 and is enclosed within the screw mandrel outer end, 11 drive screw mandrel 4 rotations to one party to turning handle, thereby brake disc 2 way rollers 1 that drive square tube 3 and below thereof move, brake disc 2 and roller 1 are tightly blocked, thereby make movable stand brake location.
When movable stand need to draw in, handle 11 is inserted handle hole 7 and is enclosed within the screw mandrel outer end, and backward rotation handle 11 drives screw mandrel 4 and rotates, thereby the brake disc 2 of drive square tube 3 and below thereof is away from roller 1, brake disc 2 and roller 1 are thrown off, thus convenient mobile movable stand.
Advantage of the present invention is: be provided with described brake device of rolling wheels for stand at movable stand base 10, brake disc 2 way rollers 1 that drive the square tube below by rotary screw rod 4 move, brake disc 2 and roller 1 are tightly blocked, movable stand base 10 is not subjected to displacement, braking quality is good, durability is strong, and is simple in structure, easy to use.
