Description

Technical Field

[0001] This utility model relates to the field of leg stretching and relaxation technology, and in particular to a leg stretching and relaxation device. Background Technology

[0002] In the process of learning dance, it is necessary to stretch and relax the legs. In the process of stretching and relaxing, a leg stretching bar is usually used. By using the leg stretching bar correctly and combining it with appropriate stretching methods, the effect of dance training can be effectively improved, helping dancers to better complete various movements.

[0003] Currently, existing leg stretching bars consist of a base, a telescopic bar, and a barre. During the stretching and relaxation of muscles, dancers place one leg straight on the leg stretching bar while keeping the other leg in a standing position and holding the barre for balance. When used in low temperatures, the outer surface of the barre is very cold, and the dancer's hands will directly contact the cold barre, causing considerable discomfort. Therefore, we propose a leg stretching and relaxation device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a leg stretching and relaxation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A leg stretching and relaxation device includes a handle, with telescopic rods symmetrically connected to the bottom end of the handle, and a support plate connected to the bottom end of each telescopic rod. A rubber sleeve is fitted on the outer side of the handle, and notches are symmetrically opened at both ends of the rubber sleeve.

[0007] Preferably, support blocks are provided on the left and right sides of the bottom end of the handle, and fixing blocks are connected to the front and back sides of the support blocks respectively. The fixing block on the front side has a threaded rod inserted through a bearing. The upper layer of the support block is covered by an arc-shaped pressure plate, and the arc-shaped pressure plate has a threaded groove inside that matches the threaded rod.

[0008] Preferably, a guide rod is connected to the upper side of the fixing block on the back, and a connecting groove adapted to the guide rod is opened inside the arc-shaped pressure plate.

[0009] Preferably, the inner side of the arc-shaped pressure plate is connected to a positioning insert, and the top of the rubber sleeve is provided with a mating groove that matches the positioning insert.

[0010] Preferably, the bottom end of the threaded rod is connected to a rotating block, and anti-slip particles are evenly distributed on the outer side of the rotating block.

[0011] Preferably, the side of the support block is connected to a mounting plate, and the inner side of the mounting plate abuts against the end of the handle. The interior of the mounting plate is connected to the handle by bolts.

[0012] Preferably, the bottom end of the rubber sleeve has a strip-shaped slit, and the inner wall of the strip-shaped slit is glued with adhesive strips.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This device, with its rubber sleeve and notch, effectively prevents dancers from directly contacting the cold barre during use. This avoids the barre's low temperature affecting comfort in low-temperature environments and allows for a more stable grip.

[0015] 2. This device is equipped with a support block and an arc-shaped pressure plate. During use, the support block and the arc-shaped pressure plate work together to facilitate the quick removal of the aged or dirty rubber sleeve from the outside of the handle and the replacement of the new rubber sleeve, thereby effectively improving the convenience of using this device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4A leg stretching and relaxation device includes a handle 1, with telescopic rods 2 symmetrically connected to the bottom end of the handle 1, and a support plate 3 connected to the bottom end of each telescopic rod 2. A rubber sleeve 4 is fitted on the outside of the handle 1, and notches 14 are symmetrically opened at the left and right ends of the rubber sleeve 4. The top end of the telescopic rod 2 is connected to the handle 1 through a connector. By opening the two sets of notches 14, the position of the connector can be left empty so that the rubber sleeve 4 can be properly fitted.

[0023] Furthermore, refer to Figure 3 and Figure 4 It can be seen that support blocks 5 are respectively provided on the left and right sides of the bottom end of the handlebar 1, and fixing blocks 6 are respectively connected to the front and back sides of the support blocks 5. The threaded rod 7 is inserted into the interior of the front fixing block 6 through the bearing. The upper layer of the support block 5 is covered by an arc-shaped pressure plate 8, and the interior of the arc-shaped pressure plate 8 is provided with a threaded groove that matches the threaded rod 7. During use, the rubber sleeve 4 can be clamped and installed by the cooperation of the support block 5 and the arc-shaped pressure plate 8. Unlike the existing technology that uses glue or tape to install the rubber sleeve 4, this can effectively prevent the rubber sleeve 4 from having adhesive residue on the outer surface of the handlebar 1 after disassembly, which is difficult to remove, thereby effectively improving the replacement efficiency of the rubber sleeve 4.

[0024] Furthermore, refer to Figure 3 It can be seen that a guide rod 11 is connected to the upper side of the back fixing block 6, and a connecting groove adapted to the guide rod 11 is opened inside the arc-shaped pressure plate 8. Through the cooperation of the guide rod 11 and the connecting groove, the arc-shaped pressure plate 8 can be vertically guided to effectively prevent the arc-shaped pressure plate 8 from rotating.

[0025] Furthermore, refer to Figure 3 It can be seen that the inner side of the arc-shaped pressure plate 8 is connected to the positioning insert 10, and the top of the rubber sleeve 4 is provided with a mating groove that matches the positioning insert 10. By using the positioning insert 10 and the mating groove inside the rubber sleeve 4, the lateral position of the rubber sleeve 4 can be restricted, so as to effectively prevent the rubber sleeve 4 from shifting laterally during use.

[0026] Furthermore, refer to Figure 3 It can be seen that the bottom end of the threaded rod 7 is connected to a rotating block 9, and anti-slip particles are evenly distributed on the outer side of the rotating block 9. Through the cooperation between the rotating block 9 and the anti-slip particles, it is easy for the staff to quickly drive the threaded rod 7 to rotate so that it can be threadedly engaged with the arc-shaped pressure plate 8, thereby driving the arc-shaped pressure plate 8 to move up and down.

[0027] Furthermore, refer to Figure 4It can be seen that the side of the support block 5 is connected to the mounting plate 12, and the inner side of the mounting plate 12 abuts against the end of the handle 1. The inside of the mounting plate 12 is connected to the handle 1 by bolts. Through the cooperation of the mounting plate 12 and the bolts, it is convenient for the staff to install the support block 5 or remove it from the end of the handle 1 to achieve quick replacement of the stripped thread rod 7.

[0028] Furthermore, refer to Figure 2 It can be seen that the bottom of the rubber sleeve 4 has a strip-shaped slit, and the inner wall of the strip-shaped slit is glued with adhesive strips 13. The two sets of adhesive strips 13 glued to the bottom of the rubber sleeve 4 can ensure the tightness of the rubber sleeve 4 wrapped around the outside of the handlebar 1, so as to effectively prevent the rubber sleeve 4 from peeling off during use. Since the adhesive strips 13 are glued to the bottom of the rubber sleeve 4, they will not contaminate the handlebar 1. When the rubber sleeve 4 needs to be replaced after it has reached the end of its service life, the staff only needs to tear or cut the adhesive strips 13 to easily remove the rubber sleeve 4 from the outside of the handlebar 1.

[0029] Working Principle: When using this utility model, the user can first place the device in a suitable position. During the leg stretching process, the rubber sleeve 4 effectively prevents the dancer's skin from directly contacting the cold barre 1, thereby reducing discomfort during the stretching process. When the rubber sleeve 4 ages or is damaged, the operator can rotate the rotating block 9 to drive the threaded rod 7 to rotate continuously, thereby enabling the arc-shaped pressure plate 8 and the threaded rod 7 to engage. At this time, the arc-shaped pressure plate 8 is forced upward, and the positioning insert 10 connected to its inner side will be pulled out from the mating groove opened at the end of the rubber sleeve 4. Then, the operator can forcefully tear or cut the two sets of rubber strips 13 connected to the bottom end of the rubber sleeve 4. At this time, the operator can remove the rubber sleeve 4 from the outside of the barre 1 as a whole and put a new set of rubber sleeve 4 on the outside of the barre 1. After the new set of rubber sleeve 4 is put on, the rotating block 9 can be rotated in the opposite direction to position and install the ends of the rubber sleeve 4. The above is the complete working principle of this utility model.
