Abstract
The utility model discloses a fitness tube with a brake device. The fitness tube comprises a tube body, wherein a chunk is respectively fixed at two ends of the tube body; the outer side of the chunk is pivoted with a handle; the chunk is provided with ratchet; and meanwhile, the handle is pivoted with a button, a grab is pivoted between the handle and the chunk, the button is linked wit the grab, and the grab is matched with the ratchet. The button is linked with the grab through a pin shaft after being optimized, the pin shaft is connected with the grab through a torsion spring, and the tail part of the grab is connected with a tension spring; and a silica gel ring is sleeved at external of the chunk. The fitness tube disclosed by the utility model has the advantages that when in use, safety and comfortability are realized.
Description
Technical field
The present invention relates to the body-building apparatus technical field, especially relate to a kind of body-building tube with brake gear.
Background technology
Along with the demand of people to various body-building apparatus, a kind of body-building tube has appearred at present.This body-building tube comprises cylindrical shell, and the two ends of this cylindrical shell are fixed with respectively a chuck, and the outside of chuck is articulated with handle.Like this, the person taking exercise can carry out waist massaging, shank or belly and the multiple exercises such as arm tension exercise, whole body or half body muscular training by this body-building tube.Simultaneously, because this body-building tube is easy to carry about with one, thus very popular.Its defect is: without enforceable brake gear, cause when cylindrical shell is relative with handle to be rotated between cylindrical shell and handle, can't stop in time, thereby the person taking exercise very easily loses balance under effect of inertia.That is, there is certain potential safety hazard.
Summary of the invention
The purpose of this invention is to provide a kind of body-building tube with brake gear, the relative rotation that it has between its cylindrical shell and handle can be stopped in time, thus safer characteristics.
The technical solution adopted in the present invention is: the body-building tube with brake gear, comprise cylindrical shell, the two ends of this cylindrical shell are fixed with respectively a chuck, and the outside of chuck is articulated with handle, described chuck is provided with ratchet, simultaneously, be articulated with button on this handle, be articulated with grab between this handle and this chuck, and this button and the interlock of this grab, this grab and this ratchet match.
Described button is by bearing pin and the interlock of this grab.
Between described bearing pin and grab, by torsion spring, connect, and the afterbody of this grab is connected with extension spring.
The outer cover of described chuck has silica gel ring.
The advantage that compared to the prior art the present invention had is: 1, safer.Body-building tube with brake gear of the present invention in use, once the person taking exercise presses button, coupler body part and ratchet that this button drives this grab carry out combination, thereby chuck can't continue to rotate forward with respect to handle, and chuck and cylindrical shell are fixed together, cylindrical shell can't continue to rotate forward simultaneously, but can rotate backward, like this, be equivalent to for being provided with a unidirectional brake gear between cylindrical shell and handle, thus safer when the person taking exercise takes exercise.Comparatively comfortable while 2, using.The outside of chuck is provided with silica gel ring, thereby has certain buffering when chuck is located to be contacted with ground etc., thereby the person taking exercise can not be subject to the vibration that ground etc. is located to give, and feels comparatively comfortable.Also can protect well product simultaneously
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the perspective exploded view of embodiments of the invention;
Fig. 2 is the sectional perspective decomposing schematic representation of the amplification of embodiments of the invention.
The specific embodiment
Embodiment, see shown in Fig. 1 and Fig. 2: have the body-building tube of brake gear, comprise cylindrical shell 10, the two ends of this cylindrical shell 10 are fixed with respectively a chuck 20, and the outside of chuck 20 is articulated with handle 40.That is, between handle 40 and chuck 20, can relatively rotate.In the present invention, this chuck 20 is provided with ratchet 21, simultaneously, on this handle 40, is articulated with button 50, between this handle 40 and this chuck 20, is articulated with grab 70, and this button 50 and 70 interlocks of this grab, and this grab 70 and this ratchet 21 match.That is, the coupler body of this grab 70 part can hook on ratchet 21.Like this, once the person taking exercise presses button 50, grab 70 moves at once and hooks on ratchet 21, make the chuck 20 only can single direction rotation with respect to handle 40, and cylindrical shell 10 and chuck 20 are fixed together, be equivalent to for cylindrical shell 10 provides unidirectional brake gear, thereby avoided cylindrical shell 10 to continue rotation and produce dangerous with respect to handle 40 under effect of inertia.Obviously, because the two ends of cylindrical shell 10 are equipped with identical button 50 and connector thereof, when the person taking exercise presses the button 50 at two ends simultaneously, cylindrical shell 10 only revolve more thorough.
Optimize, this button 50 is by bearing pin 60 and 70 interlocks of this grab.Obviously, such mechanism is beneficial to assembling.In particular, between this bearing pin 60 and grab 70, by torsion spring 81, connect, and the afterbody of this grab 70 is connected with extension spring 82.Obviously, the active force that this extension spring 82 gives grab 70 divides in the original state away from ratchet 21 hook body segment of grab 70, and after button 50 pressed, give the active force of the coupler body part one of grab 70 near ratchet 21 by torsion spring 81 after bearing pin 60 rotations, and when the active force that gives grab 70 when this torsion spring 81 is greater than extension spring 82 and gives the active force of grab 70, the coupler body of this grab 70 partly can hook on this ratchet 21, afterwards, after person taking exercise's release button 50, grab 70 resets in time under the effect of extension spring 82.
Further, the outer cover of this chuck 20 has silica gel ring 30.Like this, make the person taking exercise avoid being subject to larger vibration, thus comparatively comfortable.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
