Abstract
A wheel telescopic device comprises an upper cover, a telescopic assembly, wheels and a lower cover. The upper cover and the lower cover are fixed usually through screws. The telescopic assembly is arranged in the space formed by connecting the upper cover with the lower cover. The telescopic assembly comprises a control rod, a telescopic spring, a working plate and a reset spring. A positioning table is arranged on the working plate. The telescopic spring is fixed to the positioning table. A gourd-shaped positioning hole is formed in the middle of the working plate. One end of the control rod penetrates through a through hole in the front wall of the lower cover and protrudes out of the through hole. A protruding stop piece is arranged at the front portion of the control rod. The reset spring is arranged on the back face of the stop piece. A protruding fixing pin is arranged in the middle of the control rod. Grooves are formed in the top and the bottom of the fixing pin respectively. The wheels are arranged below the working table. The multiple wheels can be arranged, and telescopic openings corresponding to the wheels can be formed in the bottom of the lower cover and can allow the wheels to stretch out and draw back.
Description
Technical field
The present invention relates to a kind of retractor device, especially a kind of roller retractor device.
Background technology
The movement of the household goods such as case and bag, furniture, go-cart is generally all completed by roller.When these article positions fixed by needs, the general method of control roller braking that adopts realizes fixing.But, device such as the roller devices of strap brake that can realize roller braking at present on the market can only control the fixing of single or maximum two wheels, when needs control the braking of multiple roller simultaneously, multi-pass operation is wanted to brake, often miss best brake opportunity, and there is the danger of brake failure, lack convenient and safety.
Summary of the invention
Technical problem to be solved by this invention provides a kind of structure simple, designs ingenious, can control the device that multiple roller is flexible simultaneously, in order to roller retractor device that is mobile or fixing article position.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of roller retractor device, comprise upper cover, telescopic component, roller and lower cover, generally adopt between upper cover and lower cover and be screwed, the inside that described upper cover and lower cover connect and compose is provided with telescopic component, described telescopic component comprises control lever, coil tension spring, working plate, back-moving spring, described working plate is provided with positioning table, positioning table is fixed with coil tension spring, and the centre position of working plate is provided with Pear-Shaped locating hole, one end through hole run through on lower cover antetheca of described control lever protrudes from outside through hole, and the front portion of control lever is provided with protruding block, and the back side of block is provided with back-moving spring, outstanding steady pin is provided with in the middle part of control lever, described steady pin top and bottom are equipped with groove, under described roller is located at working plate, and multiple roller can be set, the telescopic mouth of corresponding roller is provided with bottom described lower cover, for the flexible turnover of roller.
As improvement, described Pear-Shaped locating hole comprises wide end and narrow end, and narrow end margin is provided with projection, and the diameter of projection mates with steady pin groove diameter, and the diameter of wide end is slightly larger than the width of steady pin.
As preferably, described control lever shape is just cuboid.
As improvement, described steady pin is cylinder, and the position of steady pin is corresponding with the position of locating hole.
As preferably, coil tension spring quantity is consistent with number of rollers, to reach best telescopic effect.
The technical solution adopted in the present invention, its advantage is: structure is simple, designs ingenious, on the position realizing mobile and fixing article, be different from traditional roller brake mode of braking, and achieve the mode of multiple roller simultaneous retractable, therefore, the present invention is worthy to be popularized.

Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the present invention is described in detail, but should not be understood as the restriction to the application.
As shown in Figures 1 to 4, the present embodiment is a kind of roller retractor device, comprise upper cover 1, telescopic component, roller 5 and lower cover 2, the inside that described upper cover 1 and lower cover 2 connect and compose is provided with telescopic component, described telescopic component comprises control lever 4, coil tension spring 6, working plate 3, back-moving spring 10, described working plate 3 is provided with positioning table, positioning table is fixed with coil tension spring, and the centre position of working plate 3 is provided with Pear-Shaped locating hole 8, one end of described control lever 4 is run through the through hole 7 on lower cover 2 antetheca and is protruded from outside through hole 7, for operator presses, and the front portion of control lever 4 is provided with protruding block 9, the rear side of block 9 is provided with back-moving spring 10, when pressing control lever 4, block 9 presses back-moving spring 10, back-moving spring 10 bullet is stretched, block 9 resilience, control lever 4 level is driven to be returned to original position, namely block 9 drives control lever 4 to do horizontal movement, control lever 4 is highly constant.
Be provided with outstanding steady pin 11 in the middle part of control lever 4, described steady pin 11 top and bottom are equipped with groove, and described roller 5 is located at working plate 3 times, are provided with the telescopic mouth of corresponding roller 5 bottom described lower cover 2.
Described Pear-Shaped locating hole 8 comprises wide end and narrow end, and narrow end margin is provided with projection, and the diameter of projection mates with steady pin 11 groove diameter, and the diameter of wide end is slightly larger than the width of steady pin 11.
Described control lever 4 shape is flat cuboid.
Described steady pin 11 is cylinder, and the position of steady pin 11 is corresponding with the position of locating hole 8.
When needs indentation roller 5, press the control lever 4 stretched out from lower cover 2 hole, steady pin 11 bottom groove on it and the little projection of the narrow end of locating hole 8 are unclamped, be moved horizontally to wide end, now apply downforce at upper cover 1, coil tension spring 6 is compressed, roller 5 indentation lower cover 2, working plate 3 moves upward relative to control lever 4, the pin 11 that is relatively fixed moves downward in locating hole 8, now unclamp control lever 3 homing, the top groove of steady pin 11 is just blocked with the narrow distal process block of locating hole 8, secures roller indentation state.
When needs stretch out roller 5, again press control lever 4, steady pin 11 top groove on it and the little projection of the narrow end of locating hole 8 are unclamped, and are moved horizontally to wide end, now coil tension spring 6 resilience, roller 5 stretches out lower cover, working plate 3 moves downward relative to control lever 4, and the pin 11 that is relatively fixed moves upward in locating hole 8, now unclamps control lever 3 homing, the bottom groove of steady pin 11 just blocks with the narrow distal process block of locating hole 8, secures roller 5 and stretches out state.
Finally, it should be noted that above what enumerate is only specific embodiments of the invention.Obviously, the invention is not restricted to above embodiment, a lot of distortion can also be had.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention, all should think protection scope of the present invention.
