Description

Technical Field

[0001] The utility model relates to the technical field of sports equipment, in particular to a foldable parallel bar. Background Art

[0002] Known sports equipment refers to a general term for various apparatuses, equipment and supplies used in competitive sports and fitness exercises, and the parallel bars are mainly composed of four uprights and two parallel horizontal bars respectively mounted on the four uprights, and then the bottoms of the four uprights are fixed on the ground or on a base with a certain strength, but the existing base is usually welded by steel plates or square steels, and the base is not only bulky, but also cannot be disassembled or folded. For individual users in the family, the existing parallel bars have the problem of not being able to be folded and stored, and taking up a large space when stored. Therefore, a Chinese utility model patent with authorization announcement number CN210963699U disclosed a foldable double bar, which includes a foldable base, four columns and two cross bars. Four studs arranged in a rectangular array are fixedly connected to the foldable base, a boss-shaped support block is screwed to the bottom of each column, and a nut is sleeved on each column. The nut and the stud are screwed to press the support block on the top of the stud, so that the column is vertically installed on the foldable base; a first connecting block is fixedly connected to the top of each column, a first screw hole is opened in the first connecting block, and two sockets are opened at the bottom of the cross bar, and a second screw hole is fixedly connected to each other on both sides of the socket in the cross bar. A connecting block, a second connecting block is provided with a second screw hole, and after the first connecting block is inserted into the socket, the adjacent first screw hole and the second screw hole are connected in series with bolts. Although this foldable base can be folded, then because the foldable base is relatively large in size and occupies a large space in order to make the support more stable, this requires larger packaging materials during the sales process, especially the existing sales on the Internet, which wastes material packaging and is more difficult to pack, increasing the transportation cost of the packaging, and also requires a larger space for the use of later consumers, especially for existing urban consumers in a smaller space, so it is necessary to improve the existing technology.

In addition, in the following description, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0029] Example 1: See Figure 1 , Figure 2 and Figure 4A foldable double bar comprises two horizontal bars 1 distributed parallel to each other and support rods 2 arranged at both ends of the horizontal bars 1. The horizontal bar 1 and the support rod 2 are connected by a movable structure 3, and a plug-in locking member 4 is arranged on the movable structure 3. The plug-in locking member 4 is installed on the movable structure 3 so that the horizontal bar 1 and the support rod 2 can be fixed and locked. This is conducive to fixing and locking the horizontal bar 1 and the support rod 2 after unfolding, which is conducive to users' exercise. The lower ends of the support rods 2 are connected by a bottom rod 5. The bottom rod 5 is not only conducive to making the support rod 2 stable on the ground, but also convenient for packaging, reducing the difficulty of packaging, reducing the investment in packaging cost, and also conducive to reducing the occupied space during actual use by users in the later stage.

[0030] Embodiment 2: It can be explained on the basis of embodiment 1, such as Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the movable structure 3 includes a fixing seat 31 arranged on the upper end surface of the support rod 2, a groove 32 on the fixing seat 31 for placing the cross bar 1, and the cross bar 1 is connected to the fixing seat 31 by a movable shaft 33, which is conducive to realizing the cross bar 1 to rotate back and forth with the movable shaft 33 as a fulcrum. A fixing hole 34 is provided on the fixing seat 31, and a locking hole 35 matching the fixing hole 34 is provided on the cross bar 1. When the cross bar 1 is rotated with the movable shaft 33 as a fulcrum so that the fixing hole 34 and the locking hole 35 coincide, the plug-in locking member 4 is inserted, and the cross bar 1 and the support rod 2 can be locked by the plug-in locking member 4. When the plug-in locking member 4 is pulled out from the fixing hole 34 and the locking hole 35, the cross bar 1 and the support rod 2 can be folded, which is conducive to reducing the difficulty and materials of packaging, reducing packaging costs, and facilitating later transportation.

[0031] I want to explain that if Figure 6 As shown, the plug-in locking member 4 includes an insert rod 41 and a pull ring 42 arranged on the insert rod 41. A protrusion 43 is arranged on the insert rod 41. This prevents the insert rod 41 from being easily withdrawn from the locking hole 35, thereby improving the safety of use.

[0032] Embodiment 3: It can be explained on the basis of embodiment 1 or embodiment 2 that the two parallel horizontal bars 1 are both hollow, which is conducive to reducing the difficulty of manufacturing the horizontal bars 1, thereby reducing the manufacturing cost, and is also conducive to reducing the weight itself, which is convenient for transportation, handling and carrying.

[0033] Embodiment 4: It can be described on the basis of Embodiment 1, Embodiment 2 or Embodiment 3, such as Figure 2 and Figure 4As shown, each horizontal bar 1 is covered with a jacket 11, which not only protects the horizontal bar 1 and reduces damage, but also helps users to use it more comfortably during training and improves the experience. It should be noted that the jacket 11 is a rubber jacket.

[0034] Embodiment 5: It can be described on the basis of Embodiment 1 or Embodiment 2 or Embodiment 3 or Embodiment 4, such as Figure 1 , Figure 2 and Figure 4 As shown, the bottom bar 5 is located in the width direction of the two support bars 2, and the two support bars 2 in the width direction can be connected by the bottom bar 5. This arrangement is reasonable, simple in structure, and easy to implement. It should be noted that a fixing plate is provided on the lower end surface of each support bar 21, and the fixing plate is fixed to the bottom bar 5 by bolts or rivets.

[0035] When the utility model is used, Figure 4 As shown, when it is necessary to fold, it is only necessary to respectively pull out the plug-in locking member 4 from the horizontal bar 1, and then rotate one end of the horizontal bar 1 and the support rod 2 on one side toward each other, and then rotate the other end of the horizontal bar 1 and the support rod 2 on the other side toward each other, so that the volume after folding is smaller, the packaging material packaging is reduced, and the packaging difficulty is reduced, thereby reducing the cost investment, and it is also conducive to narrow storage in urban spaces; Figure 1 and Figure 2 As shown, when it is needed, one only needs to rotate one end of the horizontal bar 1 in the opposite direction to the support rod 2 on one side, and then rotate the other end of the horizontal bar 1 in the opposite direction to the support rod 2 on the other side, so that the fixing hole 34 and the locking hole 35 coincide with each other, and then insert the plug-in locking piece 4, and the horizontal bar 1 and the support rod 2 can be locked by plugging and pulling the locking piece 4, and the bottom rods 5 in the width direction of the two support rods 2 are placed on the ground, so that they can be unfolded for users to exercise and use. The utility model is simple to operate and is convenient for large-scale popularization and use.

[0036] The standard parts used in this application document can all be purchased from the market, and the specific connection methods of each part adopt conventional means such as mature bolts and rivets in the prior art, which will not be described in detail here.
