The inner sleeve is threadedly connected with the bracket, and the upper end of the inner sleeve is formed with an outward flange; the lower end of the outer flange is formed with a spherical groove with an opening; the upper end of the outer sleeve is formed with a spherical groove A ball head; the ball head is connected with the outer sleeve through a connecting rod.

The inner sleeve is threadedly connected with the bracket, and the upper part of the outer sleeve is formed with a positioning hole with internal threads in the vertical direction in the axial direction; the outer wall of the inner sleeve is axially formed with a U-shaped groove; the outer wall of the outer sleeve The part is connected with the positioning nut through a hinge; the positioning nut is fixed in the U-shaped groove through the positioning hole 15.

The lower end of the outer sleeve is horizontally consistent with the axis of the scroll wheel.

The thread pitch of the inner sleeve and the outer sleeve is 1.4mm.

The threaded section of the bracket is 1/3 to 1/2 of its total length.

The axial length of the inner sleeve and the outer sleeve is 20-80cm; the preferred length of the body is 51cm.

Technical effect of the present utility model and a bit are as follows:

A new type of pommel horse according to the utility model includes a pommel horse body and its bracket. The lower part of the bracket is provided with a movable caster. The movable caster includes an inner sleeve connected to an outer sleeve. The rolling wheel on the frame, the lower end of the bracket is detachably connected with the inner sleeve. The inner and outer sleeves at the bottom of the pommel horse bracket are used for adjustment, and the relative movement characteristics of the inner and outer sleeves and the inner sleeve and the bracket can be used to adjust the height of the pommel horse when it is in use and realize the function of rolling and transporting the pommel horse, and the structure is simple. The operation is convenient, and the problem that the function of the existing pommel horse is limited is made up for.

Detailed ways

Below in conjunction with embodiment accompanying drawing, the technical scheme of the utility model is described in detail.

Embodiment 1 is described in conjunction with FIG. 1 .

A new type of pommel horse, comprising a pommel horse body 1 and its bracket 2, the lower part of the bracket 2 is provided with a movable caster 3, and the movable caster 3 includes an inner sleeve 4 connected with an outer sleeve 5, and the lower end of the outer sleeve 5 is fixed There is a wheel frame 6 and a rolling wheel 7 placed on the wheel frame 6, and the lower end of the bracket 2 is detachably connected with the inner sleeve 4.

The lower end of the bracket 2 is provided with an external thread-8 (external thread segment) on the upward axial extension section; the inner wall of the inner sleeve 4 is formed with an internal thread-9 that cooperates with the external thread-8; the outer wall of the inner sleeve 4 Two external threads 10 are formed; the inner wall of the outer sleeve 5 is formed with two internal threads 11 cooperating with the external threads two 10 .

This solution realizes the technical problem that the pommel horse can be used without rollers and can be used without putting the rollers. It also solves the situation that the height of the pommel horse can be adjusted to suit different ground flatness. The sleeve is threaded, and the inner sleeve is threaded with the bottom of the pommel horse bracket. When you need to use the rollers, you can adjust the relative distance between the inner and outer sleeves. When you need to increase the overall height of the pommel, rotate or remove the outer sleeve to adjust the inner sleeve. The relative positional relationship between the sleeve and the bracket is sufficient, the structure is simple, and the practicability is strong.

Embodiment 2 is described with reference to accompanying drawings 1, 3, 4, and 5.

An improved technical solution on the basis of Embodiment 1, the inner sleeve 4 is threadedly connected with the bracket 2, and the upper end of the inner sleeve 4 is formed with an outer flange 12; the lower end of the outer flange 12 is formed with an opening 20 spherical groove 13; the upper end of the outer sleeve 5 is formed with a ball head 14 adapted to the spherical groove 13; the ball head 14 is connected to the outer sleeve 5 through a connecting rod 19.

This solution realizes the fast and convenient use of the rollers to roll the pommel horse. It only needs to align the opening to lock the outer sleeve and then rotate it. The inner and outer sleeves can be matched in just a few seconds.

Embodiment 3 is described with reference to accompanying drawings 1 and 2.

The inner sleeve 4 is threadedly connected with the bracket 2, and the upper part of the outer sleeve 5 is formed with a positioning hole 15 with an internal thread in the vertical direction; the outer wall of the inner sleeve 4 is axially formed with a U-shaped groove 16; The outer wall of the outer sleeve 5 is connected to the positioning nut 18 through the hinge 17; the positioning nut 18 is fixed in the U-shaped groove 16 through the positioning hole 15 to lock the inner and outer sleeves.

The solution has the lowest manufacturing cost, is convenient to use, and has a simple structure, but is different from a single wheeled support.

Embodiment 4 is described with reference to FIGS. 1-5.

On the basis of the above embodiment, the lower end of the outer sleeve 5 is horizontally consistent with the axis of the scroll wheel 7.

The thread pitch of the inner sleeve 4 and the outer sleeve 5 is 1.2-1.4 mm.

The threaded section of the bracket 2 is one-third to one-half of its total length.

The axial length of the inner sleeve 4 and the outer sleeve 5 is 20-80 cm. A body length of 51 cm is preferred.

The inner sleeve 4 is at least 5 cm longer than the outer sleeve 5 .

The optimal positional relationship between the bottom end of the outer cylinder and the axis of the roller, the pitch of 1.4mm and the appropriate matching length design make it safer to use and more comfortable when screwing backwards. the
