Description

Technical Field

[0001] The present invention relates to the technical field of sports and marking devices, and particularly relates to a marking barrel and a railing device using the same. Background Art

[0002] A marking barrel is a commonly used auxiliary device in current sports. Generally, it has a conical barrel structure as a whole. A single marking barrel can be used as a fixed-point and fixed-distance marker in sports. When the marking barrel is combined with a railing, it becomes a railing device that can be used for partitioning or hurdling.

[0003] The railing device for partitioning or hurdling is formed by inserting a railing between two marking barrels of the same height. The marking barrel and the railing can be flexibly disassembled, which is convenient to use. In order to facilitate adjusting the height of the railing from the ground, many marking barrels on the market have rows of insertion holes arranged vertically on the conical barrel body. By inserting the railing into insertion holes of different heights, different heights from the ground can be achieved. Currently, the inconvenience of this railing device in use is that when changing the height of the railing from the ground, the two ends of the railing need to be pulled out from the insertion holes of the marking barrel and inserted into insertion holes of other heights. The operation takes a certain amount of time. Especially in high-density hurdling training using a large number of railing devices, changing the height of the railing once will occupy a large amount of manpower and time, reducing the training efficiency. Although there are existing technologies that attempt to improve the speed of changing the height of the railing by modifying the marking barrel. For example, Chinese Utility Model Publication CN203663461U mentions a football training hurdle. As Figure 1 shown, by arranging a triangular bracket 1-1 on one side of the marking barrel and placing the middle crossbar 1-2 on the fulcrum 1-3 of the triangular bracket for height adjustment of the hurdle. When using this hurdle, the middle crossbar 1-2 still needs to be removed for replacement, and not much time will be saved. Moreover, the support of the fulcrum 1-3 is not stable. Since the triangular bracket 1-1 is added to the whole hurdle, the size and weight of the marking barrel are increased, and instead, the structure becomes more complex and the cost is higher.

[0004] In addition, there are also some products that attempt to endow the marking barrel with local elasticity to achieve the freedom of movement of the railing, and their functions and principles are relatively complex.

[0005] In short, there has not yet appeared on the market a marking barrel and a railing device that can quickly change the height of the railing without pulling out the two ends of the railing from the insertion holes of the marking barrel, without changing the material and main structure of the marking barrel, without adding any accessories, and without increasing the weight and manufacturing cost of the marking barrel. Summary of the Invention

[0006] To solve the above problems, the present invention provides a marker bucket and a railing device using the same, mainly used to solve the problem that the railing on the marker bucket in the prior art cannot quickly change its height, and can quickly change the railing height without increasing any cost.

[0007] The technical solution of the present invention is as follows:

[0008] A marker bucket, comprising a marker bucket body, on which a plurality of jacks are distributed. The plurality of jacks at least include a first jack and a second jack, and the first jack and the second jack are arranged vertically. It is characterized in that a connecting channel communicating the first jack and the second jack is provided on the marker bucket body. The upper part of the connecting channel intersects the first jack at a first upper intersection point and a second upper intersection point respectively, and the lower part of the connecting channel intersects the second jack at a first lower intersection point and a second lower intersection point respectively. The distance between the first upper intersection point and the second upper intersection point is less than the diameter of the first jack.

[0009] Preferably, the distance between the first lower intersection point and the second lower intersection point is less than the diameter of the second jack.

[0010] Preferably, both the first jack and the second jack are circular holes, and the diameters of the first jack and the second jack are the same.

[0011] As an implementation manner, the connecting channel is communicated with the first jack and the second jack respectively through two parallel sides. The two parallel sides intersect the first jack at a first upper intersection point and a second upper intersection point respectively above, and the two parallel sides intersect the second jack at a first lower intersection point and a second lower intersection point respectively below.

[0012] As an implementation manner, the two sides of the connecting channel are not parallel. Specifically, the connecting channel is communicated with the first jack and the second jack respectively through two non-parallel "eight"-shaped or inverted "eight"-shaped sides. The two non-parallel "eight"-shaped or inverted "eight"-shaped sides intersect the first jack at a first upper intersection point and a second upper intersection point respectively above, and the lower parts of the two non-parallel "eight"-shaped or inverted "eight"-shaped sides intersect the second jack at a first lower intersection point and a second lower intersection point respectively.

[0013] Preferably, on the opposite sides of the first jack and the second jack, jacks symmetrical to the first jack and the second jack are distributed.

[0014] Preferably, the jacks and the connecting channels on the marker bucket body are all rigid channels directly opened on the marker bucket body.

[0015] A railing device includes the sign bucket and the railing as described above. Both ends of the railing can be inserted into the first jack and the second jack. At least the width dimension of the cross-section of both ends of the railing is greater than the height dimension, and the width dimension is greater than the distance between the first upper intersection point and the second upper intersection point, while the height dimension is less than the distance between the first upper intersection point and the second upper intersection point. Thus, when the end of the railing is in the first jack and lies flat along the width direction of the cross-section, the railing can be supported by the first jack. When the railing is rotated so that the width direction of the end cross-section becomes vertical, the railing can enter the second jack through the connecting channel.

[0016] Preferably, the sides in the width direction of the cross-section of both ends of the railing are straight lines, and the sides in the height direction are arcs.

[0017] Preferably, the railing is of an integral structure or a combined structure with special-shaped cross-sections at both ends.

[0018] The beneficial effects of the present invention are as follows:

[0019] A sign bucket disclosed by the present invention has a simple structure. By providing a connecting channel communicating between the jacks and the flat structure of the railing, the height can be freely changed. When changing the height, only need to twist the short side dimension of the cross-section at both ends of the railing to the position at the mouth of the connecting channel, and then the railing can be moved along the up and down direction along the connecting channel without being removed. The height replacement is very convenient. The whole can quickly change the railing height without removing the two ends of the railing from the jacks of the sign bucket, without changing the material and main structure of the sign bucket, without adding any accessories, without increasing the weight and manufacturing cost of the sign bucket. This is the first time in similar products on the market, filling the market gap, and can be widely applied to the sports field or similar fields. Description of the Drawings

Detailed implementation manners

[0033] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. It should be noted that these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. The present disclosure can be implemented in various forms and should not be limited by the embodiments described herein.

[0034] Embodiment 1

[0035] See Figure 2 , Figure 2A flag barrel of this embodiment includes a flag barrel body 10. A number of jacks are distributed on the flag barrel body 10. The number of jacks includes at least one first jack 11 and one second jack 12. The first jack 11 and the second jack 12 are arranged vertically. A connecting channel 13 communicating the first jack 11 and the second jack 12 is provided on the flag barrel body 10. The upper part of the connecting channel 13 intersects the first jack 11 at a first upper intersection point 111 and a second upper intersection point 112 respectively. The lower part of the connecting channel 13 intersects the second jack 12 at a first lower intersection point 121 and a second lower intersection point 122 respectively. The distance between the first upper intersection point 111 and the second upper intersection point 112 is less than the diameter of the first jack 11.

[0036] In this embodiment, the distance between the first lower intersection point 121 and the second lower intersection point 122 is also less than the diameter of the second jack 12. And, in this embodiment, preferably, both the first jack 11 and the second jack 12 are round holes, and the first jack 11 and the second jack 12 have the same diameter.

[0037] As an implementation manner, as Figure 2 shown, the connecting channel 13 communicates with the first jack 11 and the second jack 12 respectively through two parallel sides. The upper parts of the two parallel sides intersect the first jack 11 at a first upper intersection point 111 and a second upper intersection point 112 respectively. The lower parts of the two parallel sides intersect the second jack 12 at a first lower intersection point 121 and a second lower intersection point 122 respectively.

[0038] Next, the function of the flag barrel in this embodiment is understood with the help of a railing device applying the above flag barrel. As Figures 3 - 5 shown, a railing device includes the flag barrel as described above and a railing 20. A railing 20 is supported by two flag barrels. The two ends of the railing 20 can be inserted into the first jack 11 and the second jack 12. At least the width dimension B of the cross-section of the two ends of the railing 20 is greater than the height dimension H, and the width dimension B is greater than the distance between the first upper intersection point 111 and the second upper intersection point 112, and the height dimension H is less than the distance between the first upper intersection point 111 and the second upper intersection point 112. So that when the end of the railing 20 is in the first jack 11 and lies flat along the width direction B of the cross-section, the railing 20 can be supported by the first jack 11. When the railing 20 is rotated so that the width direction B of the end cross-section becomes vertical, the railing 20 can enter the second jack 12 through the connecting channel 13.

[0039] Preferably, as Figure 4 and Figure 5As shown, the edges of the two end portions of the railing 20 in the width direction B of the cross-section are straight lines, and the edges in the height direction H are arcs. The overall shape can be a shape like a segment of a circle with a pin at the top and a pin at the bottom. The railing 20 can move within the insertion holes and the connecting channels 13 of the marker barrel body 10 by rotating to change the positions of the long dimension and the short dimension. This non-circular shape obtained by removing the symmetric arched part from the whole circle can be adapted to the shape of the most common circular insertion holes as much as possible to improve stability and the smoothness of operation. The longest dimension of this cross-section is the diameter of its complete part, and this diameter dimension is smaller than the diameter of the insertion hole. Its shortest dimension is the remaining diameter after removing the arched part from the longest dimension, and this remaining diameter dimension is smaller than the width of the connecting channel 13. Figure 4 The railing 20 in Figure 4 is in its fixed state, with the longest dimension horizontally stuck in the insertion hole. When the height needs to be changed, rotate the railing 20 by 90 degrees so that the side where the longest dimension is located is in the same direction as the connecting channel 13, and then it can be moved up and down. After the railing 20 is moved into the next insertion hole, rotate the railing 90 degrees and reinsert it into the insertion hole.

[0040] Of course, the above-mentioned cross-section shape like a segment of a circle with a pin at the top and a pin at the bottom is only an optimal design based on the needs of stability and controllability. Other easily conceivable designs can also be used as long as they can meet the requirement that the railing 20 can quickly change the insertion hole through the connecting channel 13 by rotating and switching between a larger width direction dimension and a smaller height direction dimension. For example, if the two ends of the railing 20 are rectangular structures, its longest diameter is the long side of the rectangle, and its shortest diameter is the short side of the rectangle. If the two ends of the railing 20 are acute triangle structures, its longest diameter is the side opposite the obtuse angle, and its shortest diameter is the side opposite the acute angle. The above-mentioned shapes can all use their longest dimensions to be stuck in the insertion holes, and after rotation, use their shortest dimensions to move within the connecting channel 13.

[0041] Preferably, insertion holes symmetrical to the first insertion hole 11 and the second insertion hole 12 are distributed on the opposite sides of the first insertion hole 11 and the second insertion hole 12. As a design to meet the market needs, the vertically arranged insertion holes are symmetrically distributed on both sides of the marker barrel body 10, and there are multiple groups of such symmetrically arranged insertion hole groups on one marker barrel body 10, such as two groups, which facilitates the use of the marker barrel.

[0042] The marker barrel of this embodiment is easy to manufacture. The insertion holes and the connecting channels 13 on the marker barrel body 10 are all rigid channels directly opened on the marker barrel body 10, and can be integrally formed with the marker barrel body 10 or formed through simple machining during manufacturing. This is much more practical and easier than some current design ideas that attempt to endow the marker barrel with local elasticity to achieve the freedom of movement of the railing.

[0043] According to the convenience of production, the railing 20 is of an integral structure or a combined structure with special-shaped cross-sections at both ends. For example, the middle part of the railing 20 after removing the two end parts is still a common circular structure, which conforms to people's normal usage habits.

[0044] It should be noted that the number of vertical jacks on each sign barrel is not particularly limited in the present invention. For the sign barrels on the current market, the number of vertical jacks is generally 2 - 5, such as Figure 2 As shown, the sign barrel in this embodiment may further have a third jack 14, which is arranged below the second jack 12. And a connecting channel 13 communicating the second jack 12 and the third jack 14 is provided on the sign barrel body 10. The upper part of the connecting channel 13 intersects the second jack 12 at two points respectively, and the distance between the two points is less than the diameter of the second jack 12.

[0045] Furthermore, the sign barrel may have a fourth jack 15, which is arranged below the third jack 14. And a connecting channel 13 communicating the third jack 14 and the fourth jack 15 is provided on the sign barrel body 10. The upper part of the connecting channel 13 intersects the third jack 14 at two points respectively, and the distance between the two points is less than the diameter of the third jack 14.

[0046] In addition, similar to most of the existing technologies, the sign barrel body 10 is of a conical structure as a whole, can be stacked, and any design in the existing technologies can also be added, such as opening at the upper part to facilitate inserting vertical railings, etc.

[0047] Embodiment 2

[0048] In order to further improve the smoothness of the operation when switching the railing 20 between jacks, as a different implementation method from Embodiment 1, starting from this embodiment, the two sides of the connecting channel 13 are no longer parallel. By way of example, the connecting channel 13 is connected to the first jack 11 and the second jack 12 respectively through two non-parallel "V" - shaped or inverted "V" - shaped sides. The upper parts of the two non-parallel "V" - shaped or inverted "V" - shaped sides intersect the first jack 11 at a first upper intersection point 111 and a second upper intersection point 112 respectively, and the lower parts of the two non-parallel "V" - shaped or inverted "V" - shaped sides intersect the second jack 12 at a first lower intersection point 121 and a second lower intersection point 122 respectively.

[0049] Figure 6 Shows the first special case where the two sides of the connecting channel 13 are not parallel. With this structure, at least when switching the railing 20 between different jacks from bottom to top, the smoothness is better.

[0050] Embodiment 3

[0051] Figure 7 Shows a second special case where two sides of the connecting channel 13 are not parallel. With this structure, at least when the railing 20 is switched between different jacks from top to bottom, the smoothness is better.

[0052] Embodiment 4

[0053] Figure 8 Shows a third special case where two sides of the connecting channel 13 are not parallel. With this structure, at least when the railing 20 is switched between the first jack 11 and the second jack 12 from top to bottom and between the fourth jack 15 and the third jack 14 from bottom to top, the smoothness is better.

[0054] Embodiment 5

[0055] Figure 9 Shows a fourth special case where two sides of the connecting channel 13 are not parallel. With this structure, at least when the railing 20 is switched between the second jack 12 and the first jack 11 from bottom to top and between the third jack 14 and the fourth jack 15 from top to bottom, the smoothness is better.

[0056] As described above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes, increases or decreases, or replacements that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
