[0025] The structure of the present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1 、 Figure 5 As shown, the utility model is a connection structure of the base column 3 of a hurdle frame, including a support leg 1, a column 3 and a connecting rod 2, and is characterized in that a lateral slot 5 is opened on one side of the support leg 1, a connecting piece 4 is provided at the end of the connecting rod 2, the lower end of the column 3 is located in the lateral slot 5, the connecting piece 4 is connected to the column 3 and the support leg 1 by bolts, and the connecting piece 4 and the lateral slot 5 together hold the column 3 tightly and fix it.

[0027] The column 3 of the present invention is directly placed in the lateral notch 5 on the leg 1, eliminating the socket on the upper surface of the leg 1 used to insert the column 3 in the prior art. The column 3 is tightly held by the connector 4 integral with the connecting rod 2 in conjunction with the lateral notch 5. This tightening fixation method can avoid the formation of gaps between the column 3 and the lateral notch 5 and the connector 4, thereby preventing the column 3 from shaking. In the prior art, the connector 4 at the end of the connecting rod 2 is only connected to the leg 1 by bolts, which makes it difficult to ensure the connection strength. In this application, the connector 4 at the end of the connecting rod 2 is connected to both the column 3 and the leg 1 at the same time, which can greatly enhance the connection strength of the connection structure.

[0028] Two embodiments are given below for a cylindrical column 3 and a column 3 with a rectangular column structure.

[0029] Example 1

[0030] like Figures 1 to 4 As shown, as the first form of the connection structure of the base column 3 of the hurdle frame of the present invention, the column 3 is cylindrical, and the lateral slot 5 on the corresponding support leg 1 is arc-shaped, which is close to a semicircle, and the lower end of the cylindrical column 3 is placed in the arc-shaped lateral slot 5.

[0031] At the same time, the connecting member 4 includes an arc portion 4-1 and connecting plates 4-2 located on both sides of the arc portion 4-1. The arc portion 4-1 is used to cooperate with the arc-shaped lateral slot 5 to hold the column 3 tightly. The arc shape of the arc portion 4-1 is also approximately semicircular, and the connecting plate 4-2 is used to directly connect with the support leg 1.

[0032] The connecting rod 2 and the connecting member 4 are an integral structure. In this embodiment, the end of the connecting rod 2 is welded to the arc portion 4-1. In order to facilitate welding and ensure the structural strength after welding, an arc is added to the end of the connecting rod 2 before welding. The arc is consistent with the arc of the arc portion 4-1, so that the end of the connecting rod 2 can fit tightly with the arc portion 4-1, and then welding is performed to weld the connecting rod 2 and the arc portion 4-1 into one.

[0033] Among them, such as Figure 2 As shown, the height of the arc portion 4-1 is greater than the height of the upper surface of the connecting rod 2, a first bolt hole 6 is opened on the connecting plate 4-2, and a second bolt hole 7 is opened on the arc portion 4-1 higher than the upper surface of the connecting rod 2. A bolt is passed through the first bolt hole 6 to fix the connecting part to the support leg 1, and a bolt is passed through the second bolt hole 7 to fix the connecting part to the column 3.

[0034] Correspondingly, such as Figure 3 As shown, third bolt holes 8 passing through the leg 1 are respectively opened on both sides of the lateral slot 5 on the leg 1, and the third bolt hole 8 corresponds to the first bolt hole 6. A fourth bolt hole 9 is opened on the column 3, and the fourth bolt hole 9 corresponds to the second bolt hole 7, so as to facilitate the connection and fixation of the bolts.

[0035] Since the arc portion 4-1 is higher to facilitate the connection between the connector 4 and the column 3, and the connecting plate 4-2 only needs to be connected to the support leg 1, in order to ensure the overall structural strength of the connector 4, the upper edge of the connecting plate 4-2 is a downward-sloping bevel from the arc portion 4-1 to the outside.

[0036] In this embodiment, the ends of connecting rod 2 are welded to arcuate portions 4-1 of connector 4, ensuring strong connection between connecting rod 2 and connector 4. Furthermore, the connection plates 4-2 on either side and the arcuate portions 4-1 also provide strong structural strength, thereby ensuring strong connection between connecting rod 2 and leg 1. The uprights 3 are secured by both connector 4 and lateral notches 5 on leg 1, ensuring their stability. This structure ensures that the hurdle frame base remains detachable while maintaining strong structural strength and stability in the assembled state.

[0037] Example 2

[0038] like Figures 5 to 8 As shown, as the second form of the connection structure of the base column 3 of the hurdle frame of the present invention, the column 3 is a rectangular column, and the lateral slot 5 on the corresponding support leg 1 is rectangular. The width of the lateral slot 5 is slightly larger than the width of the column 3, so that the lower end of the column 3 can be smoothly placed into the lateral slot 5.

[0039] In this embodiment, the connecting member 4 includes a bottom plate 4-3 and side plates 4-4 located on both sides of the bottom plate 4-3. The bottom plate 4-3 and the side plates 4-4 are U-shaped. When in use, after the column 3 is placed into the lateral slot 5 of the leg 1, the side plates 4-4 of the connecting member 4 are also inserted into the gap between the lateral slot 5 and the column 3. The column 3 is tightly held and fixed by the U-shaped connecting member 4 and the rectangular lateral slot 5.

[0040] The connecting rod 2 is welded to the middle part of the base plate 4-3. A fifth bolt hole 10 is opened at the lower end of the base plate 4-3, and a sixth bolt hole 11 is opened at the upper end of the base plate 4-3. Bolts are passed through the fifth bolt hole 10 to fix the connecting piece 4, the column 3 and the support leg 1, and bolts are passed through the sixth bolt hole 11 to fix the connecting piece 4 to the column 3.

[0041] Correspondingly, a seventh bolt hole 12 is opened on the support leg 1, which corresponds to the lateral slot 5 and the fifth bolt hole 10, and two eighth bolt holes 13 are opened on the column 3, which correspond to the fifth bolt hole 10 and the sixth bolt hole 11 respectively.

[0042] The lower bolts pass through the fifth bolt hole 10 on the connector 4, the eighth bolt hole 13 below the column 3, and the seventh bolt hole 12 on the leg 1 to simultaneously securely connect the connector 4, the column 3, and the leg 1. The upper bolts pass through the sixth bolt hole 11 on the connector 4 and the eighth bolt hole 13 above the column 3 to securely connect the connector 4 to the column 3. This structure secures the rectangular column 3, the connecting rod 2, and the leg 1 in this embodiment.

[0043] Furthermore, in order to further ensure that the column 3 does not shake, the distance between the outer sides of the two side panels 4-4 is consistent with the width of the lateral slot 5, and the distance between the inner sides of the two side panels 4-4 is consistent with the width of the column 3. The length of the side panel 4-4 is less than the depth of the lateral slot 5. In this way, after the two side panels 4-4 are inserted into the lateral slot 5, the side panels 4-4 completely fill the gap between the column 3 and the side wall of the lateral slot 5, effectively preventing the column 3 from shaking.

[0044] In this embodiment, the rectangular columns 3 are held securely in place by U-shaped connectors 4 in conjunction with rectangular side notches 5. A bolt secures the connector 4 on the connecting rod 2 to the columns 3, while another bolt passes through the connector 4, the columns 3, and the legs 1, securing the connecting rod 2, the columns 3, and the legs 1 together. The legs 1, connecting rod 2, and the columns 3 are detachable, facilitating assembly and transport. In the assembled state, the strength and stability of the structure are maintained.

[0045] Example 3

[0046] This embodiment discloses a hurdle frame, including a base, two upright posts 3 and a cross bar located between the two upright posts 3. The base includes two legs 1 and a connecting rod 2 located between the two legs 1. A lateral slot 5 is provided on one side of the leg 1. A connecting piece 4 is provided at the end of the connecting rod 2. The lower end of the upright post 3 is located in the lateral slot 5. The connecting piece 4 is connected to the upright post 3 and the leg 1 by bolts, and the connecting piece 4 and the lateral slot 5 together hold the upright post 3 tightly and securely.

[0047] The upright posts 3 are generally adjustable upright posts 3 so as to adjust the height of the crossbar. Alternatively, the upright posts 3 may be adjustable so that the height of the crossbar is fixed.

[0048] In addition, the pillar 3 generally has two shapes, one is a cylindrical pillar 3 and the other is a rectangular pillar 3.

[0049] As a first form of hurdle frame, the column 3 is cylindrical, the lateral notch 5 is arc-shaped, the connector 4 includes an arc portion and connecting plates located on both sides of the arc portion, the connecting rod 2 is connected to the arc portion, and the height of the arc portion is greater than the height of the upper surface of the connecting rod 2. A first bolt hole is opened in the connecting plate, and a second bolt hole is opened in the arc portion. A bolt is inserted through the first bolt hole to fix the connecting portion to the support leg 1, and a bolt is inserted through the second bolt hole to fix the connecting portion to the column 3. The specific structure of the base-column 3 connection structure of this type is described in detail in Example 1, and will not be repeated here.

[0050] As a second form of hurdle frame, the column 3 is a rectangular column, the lateral notch 5 is rectangular, and the connector 4 includes a base plate and side plates located on both sides of the base plate. The base plate and the side plates form a U-shaped structure. The connecting rod 2 is connected to the middle of the base plate, and the two side plates are inserted into the lateral notch 5. A fifth bolt hole is opened at the lower end of the base plate, and a sixth bolt hole is opened at the upper end of the base plate. Bolts are inserted through the fifth bolt hole to fix the connector 4 to the column 3 and the support leg 1. Bolts are inserted through the sixth bolt hole to fix the connector 4 to the column 3. This type of base-column 3 connection structure is specifically referred to in Example 2 and will not be repeated here.
