Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1-4, the support sleeve of the present embodiment comprises an outer tube 1 and an inner tube 2, and further comprises a roller assembly, wherein the roller assembly comprises a sleeve 3 and a wheel pair, the wheel pair comprises two rollers 31 arranged oppositely, and the rollers 31 are rotatably mounted inside the sleeve 3; the pipe sleeve 3 is inserted in the outer pipe 1, the inner pipe 2 is inserted in the pipe sleeve 3, the rollers 31 abut against the outer pipe wall of the inner pipe 2, and the inner pipe 2 is sandwiched between the two rollers 31.

Specifically, the inner tube 2 of the sliding sleeve assembly of the present embodiment is mounted on the outer tube 1 by a roller assembly, and the inner tube 2 and the outer tube 1 are spaced apart by the roller assembly. Wherein the inner tube 2 is clamped between two rollers 31 of the wheel pair, and the rollers 31 can clamp and support the inner tube 2. In the process of pushing and pulling the inner tube 2, the inner tube 2 can be smoothly extended or retracted under the guidance of the roller 31, so that the inner tube 2 can smoothly slide. After the inner tube 2 is adjusted in place, the inner tube 2 is clamped between the two rollers 31, and the shaking of the inner tube 2 can be reduced or avoided through the clamping of the rollers 31. The positioning manner of the inner tube 2 is the same as that in the prior art, and the positioning can be realized by using a bolt or the like, which is not limited and described herein.

Further, the roller 31 includes a rotating shaft 312 and a roller body 311, the roller body 311 is sleeved outside the rotating shaft 312, and the rotating shaft 312 is rotatably installed in the tube housing 3. Specifically, the roller body 311 is a hollow structure and is sleeved on the rotating shaft 312, the roller body 311 is in contact with the inner tube 2 to clamp and position the inner tube 2, and the rotating shaft can rotate relative to the tube sleeve 3 to ensure that the inner tube 2 can slide smoothly. Wherein, the axis that the middle part of roll body 311 circled the axis 312 is provided with annular groove 3111, and annular groove 3111 can reduce the area of contact between roll body 311 and the inner tube 2, when the gyro wheel 31 appears and rotates unsmoothly, because the area of contact of roll body 311 and inner tube 2 is less, can reduce sliding friction, still ensures the smooth and easy slip of inner tube 2.

Still further, in order to facilitate the installation of the roller 31, the pipe sleeve 3 is provided with oppositely arranged installation seats 32, and the rotating shaft 312 is rotatably installed on the installation seats 32. Specifically, a shaft hole (not labeled) is formed in the mounting seat 32, and the rotating shaft 312 is inserted into the shaft hole. Wherein, the mounting seats 32 are formed at the end of the pipe sleeve 3, and for more stable and reliable mounting of the inner pipe 2, the mounting seats 32 are respectively provided at the two ends of the pipe sleeve 3, and the mounting seats 32 at the two ends of the pipe sleeve 3 can more effectively support the inner pipe 2 in the length direction, so as to ensure that the inner pipe 2 and the outer pipe 1 can be coaxially arranged.

Furthermore, for the convenience of assembling the pipe sleeve 3 on the outer pipe 1, the outer side surface of the mounting seat 32 is further provided with an elastic rib 321, and the elastic rib 321 abuts against the inner pipe wall of the outer pipe 1. After the pipe sleeve 3 is inserted into the outer pipe 1, the elastic rib 321 is firmly pressed against the inner pipe wall of the outer pipe 1 by the extrusion deformation of the inner pipe wall of the outer pipe 1, so that the pipe sleeve 3 is firmly and reliably mounted on the outer pipe 1.

Preferably, the mounting seat 32 is provided with a flange structure 322 on both sides thereof, which is sandwiched between the inner tube 2 and the outer tube 1. Specifically, two rollers 31 can position one pair of side walls of the inner tube 2, and the flange structure 322 can position the other pair of side walls of the inner tube 2, so that the four side surfaces of the inner tube 2 can be supported more effectively. And because the overall size of the flanging structure 322 is small, the sliding friction force generated by the flanging structure is small in the sliding process, and the smooth sliding of the inner pipe 2 can still be ensured.

As shown in fig. 5, the present invention also provides an exercise apparatus including the support sleeve 100. By way of example, for example: the exercise apparatus may further comprise a base 101 and a seat 102, the outer tube of the support sleeve 100 being fixedly mounted on the base 101 and the seat 102 being mounted on the inner tube of the support sleeve 100.

The utility model provides a support sleeve and a body-building device, which are characterized in that the rollers which are arranged oppositely are arranged in the pipe sleeve, after the inner pipe is arranged in the outer pipe through the pipe sleeve, the inner pipe is clamped between the two rollers; in the process of pushing and pulling the inner pipe, the inner pipe can drive the roller to rotate, so that the inner pipe can smoothly slide relative to the outer pipe; in addition, after the inner pipe is adjusted to the right position, the inner pipe is clamped between the two rollers, so that the inner pipe can be further prevented or reduced from shaking, the supporting sleeve can smoothly slide and shake less, and the user experience of the body-building equipment is improved.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
