[0001] This application relates to the field of working platforms, and in particular, to a tripod. Background Art

[0002] A tripod is a bracket used to support equipment. According to different usage scenarios and requirements, tripods can be divided into many types, such as: tripods, monopods, and quadruple brackets. The factors to consider when choosing a suitable tripod are: load-bearing capacity, material and weight, stability, etc.

[0003] To facilitate the operation of a cutting machine, the cutting machine is generally installed on a tripod for use. For example, a Chinese patent with the patent number CN2386944Y discloses a ceramic tile cutting machine. A water tank bracket assembly, a caster assembly, and a water trough are installed on the tripod assembly. There is a guide rod assembly and a main support on the water tank bracket assembly. There is a cutting table on the guide rod assembly, and a machine base on the main support. There is a motor, a machine base shaft, a shaft sleeve, and a saw blade shaft on the machine base. A saw blade is installed on the saw blade shaft. This machine uses water cooling for heat dissipation, reduces wear and pollution, can achieve polygon cutting at any angle, the cutting depth can reach 80 mm, the accuracy is 0.25 mm, the cut edge is neat and smooth, and the glaze surface has no chipping. It is suitable for cutting ceramic tiles, glazed tiles, wear-resistant tiles, granite, and marble.

[0004] Regarding the above related technologies, the inventor believes that when an external force is applied to the tripod, the center of gravity of the tripod on the pushed side instantaneously deviates outside the tripod, causing the tripod to tip over and having insufficient stability, leaving room for improvement. Utility Model Content

[0005] In order to improve the problem that when an external force is applied to the tripod, the center of gravity of the tripod on the pushed side instantaneously deviates outside the tripod, causing the tripod to tip over and having insufficient stability, this application provides a tripod.

[0006] The tripod provided by this application adopts the following technical solutions:

[0007] A tripod, comprising a bracket group, a front panel and a rear panel. The number of the bracket groups is two, and the two bracket groups are arranged in parallel. The bracket group includes a first bracket and a second bracket. Two ends of the front panel are respectively fixed to one ends of the first brackets of the two bracket groups away from the ground, and two ends of the rear panel are respectively fixed to one ends of the second brackets of the two bracket groups away from the ground. The tripod further includes a first leg and a second leg. The first leg includes a first connecting portion and a first supporting portion. The first connecting portion is connected to one side of the first bracket close to the ground, and the first supporting portion is fixedly connected to one end of the first connecting portion away from the first bracket. The two first supporting portions on different first brackets gradually move away from each other from the side close to the first connecting portion to the side away from the first connecting portion. The second leg includes a second connecting portion and a second supporting portion. The second connecting portion is connected to one side of the second bracket close to the ground, and the second supporting portion is fixedly connected to one end of the second connecting portion away from the second bracket. The two second supporting portions on different second brackets gradually move away from each other from the side close to the second connecting portion to the side away from the second connecting portion.

[0008] By adopting the above technical solution, by arranging the outwards splayed legs, a more stable support is provided, so that although the center of gravity is shifted due to being pushed, the connection between the legs and the ground is still outside the center of gravity, making it not easy to overturn, and the stability of the tripod is improved.

[0009] Optionally, a first anti-slip foot pad is fixedly connected to one end of the first supporting portion away from the first connecting portion, and a second anti-slip foot pad is fixedly connected to one end of the second supporting portion away from the second connecting portion. The end face of the first anti-slip foot pad away from the first supporting portion is in contact with the ground, and the end face of the second anti-slip foot pad away from the second supporting portion is in contact with the ground.

[0010] By adopting the above technical solution, on the one hand, the first anti-slip foot pad and the second anti-slip foot pad are arranged to increase the friction coefficient between the first bracket and the second bracket. On the other hand, the end faces of the first anti-slip foot pad and the second anti-slip foot pad are flush with the ground, so that the contact area between the first bracket, the second bracket and the ground is increased. The two are combined, and when under the same gravity, the friction between the first bracket, the second bracket and the ground is increased, improving the anti-slip property and stability of the tripod.

[0011] Optionally, the first connecting portion is passed through one end of the first bracket close to the ground. A first bolt is passed through the first bracket. A plurality of first through holes are provided on the first connecting portion. The first through holes are arranged along the length direction of the first connecting portion. The first bolt is passed through one of the first through holes. A first nut is threadedly connected to the first bolt. The first nut and the bolt head of the first bolt respectively abut against both sides of the first bracket. The second connecting portion is passed through one end of the second bracket close to the ground. A second bolt is passed through the second bracket. A plurality of second through holes are provided on the second connecting portion. The second through holes are arranged along the length direction of the second connecting portion. The second bolt is passed through one of the second through holes. A second nut is threadedly connected to the second bolt. The second nut and the bolt head of the second bolt respectively abut against both sides of the second bracket.

[0012] By adopting the above technical solution, by passing the first bolt through the first through holes at different positions and passing the second bolt through the second through holes at different positions, the relative positions of the first leg and the first bracket, and the second leg and the second bracket can be changed, so as to adjust the height of the overall tripod, adapt to environments with different height requirements, and improve the adaptability of the tripod.

[0013] Optionally, a first driving block is sleeved on the first nut, and a second driving block is sleeved on the second nut.

[0014] By adopting the above technical solution, through the arrangement of the first driving block and the second driving block, it is possible to threadedly rotate the first nut and the second nut without a wrench, improving the convenience of disassembling and installing the first bolt and the second bolt.

[0015] Optionally, it further includes a first cross bar, first wing bolts, a second cross bar and second wing bolts. The number of the first wing bolts is two. The two first wing bolts are respectively passed through both ends of the first cross bar. The two first wing bolts are respectively threadedly connected to the two first brackets in a one-to-one correspondence. The first cross bar abuts against one side of the two second brackets close to the ground and one side of the two first brackets far from the ground. The number of the second wing bolts is two. The two second wing bolts are respectively passed through both ends of the second cross bar. The two second wing bolts are respectively threadedly connected to the two second brackets in a one-to-one correspondence. The second cross bar abuts against one side of the two first brackets close to the ground and one side of the two second brackets far from the ground.

[0016] By adopting the above technical solutions, the first crossbar and the second crossbar are provided. On the one hand, they respectively support the second bracket and the first bracket of the same bracket group, ensuring the angle between the first bracket and the second bracket of the same bracket group and improving the structural strength of the installation of the first bracket and the second bracket of the same bracket group. On the other hand, they connect the two first brackets or the second brackets of different bracket groups, improving the structural strength and stability of the overall tripod.

[0017] Optionally, a first screw cylinder is fixedly connected to the first bracket, the first wing bolt is threadedly connected inside the first screw cylinder, a second screw cylinder is fixedly connected to the second bracket, and the second wing bolt is threadedly connected inside the second screw cylinder.

[0018] By adopting the above technical solutions, the settings of the first screw cylinder and the second screw cylinder increase the contact area during the threaded connection between the first wing bolt and the first bracket, and between the second bolt and the second bracket, improving the connection stability between the first wing bolt and the first bracket, and between the second wing bolt and the second bracket, and further improving the connection stability between the first crossbar and the first bracket, and between the second crossbar and the second bracket.

[0019] Optionally, it further includes a horizontally arranged reinforcing lock piece. A third bolt passes through the first bracket, a third nut is threadedly connected to the third bolt. The reinforcing lock piece is provided with a first mounting hole, the third bolt passes through the first mounting hole, the third nut abuts against the side of the reinforcing lock piece away from the first bracket, the screw head of the third bolt abuts against the side of the first bracket away from the reinforcing lock piece.

The side of the reinforcing lock piece away from the first mounting hole is provided with a second mounting hole, the fourth bolt passes through the second mounting hole, the fourth nut abuts against the side of the reinforcing lock piece away from the second bracket, and the screw head of the fourth bolt abuts against the side of the second bracket away from the reinforcing lock piece.

[0020] By adopting the above technical solutions, since the placement of the cutting machine on the tripod will cause the ends of the first bracket and the second bracket away from the connection to move away from each other, the setting of the reinforcing lock piece enables the first bracket and the second bracket within the same group to be further connected and not easily move away from each other, improving the structural strength of the installation of the first bracket and the second bracket of the same bracket group.

[0021] Optionally, the first mounting hole is arranged in a waist shape along the length direction of the reinforcing lock piece.

[0022] By adopting the above technical solutions, the first mounting hole is arranged in a waist shape, enabling the first bracket and the second bracket of the same bracket group to approach each other, adapting to bracket groups at different angles and improving the adaptability of the reinforcing lock piece.

[0023] Optionally, a notch is provided on the reinforcing lock piece for moving the fourth bolt out of the second mounting hole in a direction parallel to the plane where the reinforcing lock piece is located. The notch communicates with the second mounting hole, and a baffle is fixedly connected to the side wall of the notch away from the first mounting hole.

[0024] By adopting the above technical solution, the arrangement of the notch and the baffle enables the fourth bolt to be detached from the reinforcing lock piece through the notch while ensuring that the fourth bolt is not easily detached from the second mounting hole at the current included angle between the first bracket and the second bracket, without the need to rotate the fourth nut to separate the fourth nut and the fourth bolt, thus improving the convenience of disassembling the reinforcing lock piece.

[0025] Optionally, a dust collection bag is provided on the rear panel.

[0026] By adopting the above technical solution, the arrangement of the dust collection bag enables the collection of debris and dust generated during the use of the cutting machine, thus improving the versatility of the tripod.

[0039] The following further describes the present application in detail with reference to the attached Figure 1-7 drawings.

[0040] An embodiment of the present application discloses a tripod. Referring to Figure 1 , a tripod includes a bracket group 1, a front panel 2 and a rear panel 3. The bracket group 1 stands on the ground to play a supporting role. The number of the bracket groups 1 is two, and the two bracket groups 1 are arranged in parallel. The bracket group 1 includes a first bracket 11 and a second bracket 12, and the first bracket 11 and the second bracket 12 are fixedly connected to each other. The two ends of the front panel 2 are respectively installed on the two first brackets 11 and are in a horizontal state to provide a corresponding supporting surface for the cutting machine. The two ends of the rear panel 3 are respectively installed on the two second brackets 12 and are in a horizontal state to provide a corresponding supporting surface for the cutting machine.

[0041] Referring to Figure 1 , a dust collection bag 4 is further installed on the rear panel 3 to facilitate the collection of waste chips and residues cut by the cutting machine.

[0042] Referring to Figure 2, on the side of the first support 11 close to the ground, there is a first leg 13. The first leg 13 includes a first connecting portion 131 and a first supporting portion 132, and the first connecting portion 131 and the first supporting portion 132 are fixedly connected. The first connecting portion 131 is passed through one end of the first support 11 close to the ground. A first bolt 111 is passed through the first support 11. The first connecting portion 131 has a first through hole 1311. When the first connecting portion 131 is passed through the first support 11, the first bolt 111 is passed through the first through hole 1311, so that the first leg 13 is installed on the first support 11. The number of the first through holes 1311 is several and they are arranged along the length direction of the first connecting portion 131. Thus, when the first bolt 111 is passed through different first through holes 1311, the relative positions of the first support 11 and the first leg 13 are different to adjust the overall height. To prevent the first bolt 111 from disengaging from the first through hole 1311, a first nut 112 is threadedly connected to the first bolt 111. The bolt head of the first bolt 111 and the first nut 112 respectively abut against both sides of the first support 11. One end of the first supporting portion 132 away from the first connecting portion 131 is fixedly connected with a first anti-slip foot pad 133. The end face of the first anti-slip foot pad 133 away from the first supporting portion 132 is in contact with the ground to increase the friction between the first support 11 and the ground. To facilitate the threaded rotation of the first nut 112, a first driving block 113 is sleeved on the first nut 112.

[0043] Two first supporting portions 132 on different first supports 11 gradually move away from the side close to the first connecting portion 131 to the side away from the first connecting portion 131, so that the two first supporting portions 132 are arranged in an outwardly flared shape, thereby increasing the supporting force of the first support 11.

[0044] Refer to Figure 3, one side of the second support 12 close to the ground has a second leg 14. The second leg 14 includes a second connecting portion 141 and a second supporting portion 142, and the second connecting portion 141 and the second supporting portion 142 are fixedly connected. The second connecting portion 141 is inserted through one end of the second support 12 close to the ground. A second bolt 121 is inserted through the second support 12. The second connecting portion 141 has a second through hole 1411. When the second connecting portion 141 is inserted into the second support 12, the second bolt 121 is inserted into the second through hole 1411, so that the second leg 14 is installed on the second support 12. The number of the second through holes 1411 is several and is arranged along the length direction of the second connecting portion 141. Thus, when the second bolt 121 is inserted into different second through holes 1411, the relative positions of the second support 12 and the second leg 14 are different to adjust the overall height. To prevent the second bolt 121 from detaching from the second through hole 1411, a second nut 122 is threadedly connected to the second bolt 121. The bolt head of the second bolt 121 and the second nut 122 respectively abut against both sides of the second support 12. One end of the second supporting portion 142 away from the second connecting portion 141 is fixedly connected with a second anti-slip foot pad 143. The end face of the second anti-slip foot pad 143 away from the second supporting portion 142 is in contact with the ground to increase the friction between the second support 12 and the ground. To facilitate the threaded rotation of the second nut 122, a second driving block 123 is sleeved on the second nut 122.

[0045] The two second supporting portions 142 on different second supports 12 gradually move away from the side close to the second connecting portion 141 to the side away from the second connecting portion 141, so that the two second supporting portions 142 are arranged in an outward V shape, thereby increasing the supporting force of the second support 12.

[0046] Referring to Figure 1 and Figure 4 , to further strengthen the structural strength of the tripod, a transverse strengthening component 5 is further included. The transverse strengthening component 5 includes a first cross bar 51 and a second cross bar 52. First butterfly bolts 511 are respectively inserted through both ends of the first cross bar 51. A first screw cylinder 114 is fixedly connected to the first support 11. After the first butterfly bolt 511 passes through the first cross bar 51, it is threadedly connected into the first screw cylinder 114, so that both ends of the first cross bar 51 are fixed on the first supports 11 of different support groups 1. The first cross bar 51 abuts against one side of the two second supports 12 close to the ground and one side of the two first supports 11 away from the ground, so that one end of the second support 12 close to the rear panel 3 and one end of the first support 11 close to the ground will not approach each other.

[0047] Referring to Figure 5, at both ends of the second crossbar 52, there are respectively passed through second wing bolts 521. A second screw cylinder 124 is fixedly connected to the second support 12. After passing through the second crossbar 52, the second wing bolts 521 are threadedly connected into the second screw cylinder 124, so that both ends of the second crossbar 52 are fixed on the second supports 12 of different support groups 1. The second crossbar 52 abuts against the sides of the two first supports 11 close to the ground and the sides of the two second supports 12 away from the ground, so that the ends of the first support 11 close to the front panel 2 and the ends of the second support 12 close to the ground will not approach each other.

[0048] Referring to Figure 6 , in order to further strengthen the structural strength of the tripod, a reinforcing lock piece 6 is also included. A third bolt 115 is passed through the first support 11, and a third nut 116 is threadedly connected to the third bolt 115. In the embodiment of the present application, a driving block is also sleeved on the third nut 116 to facilitate the rotation of the third nut 116 without tools. The reinforcing lock piece 6 has a first mounting hole 61, and the third bolt 115 is passed through the first mounting hole 61, so that the reinforcing lock piece 6 is mounted on the first support 11. The first mounting hole 61 is arranged in a waist shape along the length direction of the reinforcing lock piece 6, so that the rotation radius of the reinforcing lock piece 6 can be controlled. The third nut 116 abuts against the side of the reinforcing lock piece 6 away from the first support 11, and the screw head of the third bolt 115 abuts against the side of the first support 11 away from the reinforcing lock piece 6, thereby preventing the reinforcing lock piece 6 from detaching from the first support 11.

[0049] A fourth bolt 125 is passed through the second support 12, and a fourth nut 126 is threadedly connected to the fourth bolt 125. In the embodiment of the present application, a driving block is also sleeved on the fourth nut 126 to facilitate the rotation of the fourth nut 126 without tools. The reinforcing lock piece 6 has a second mounting hole 62, and the fourth bolt 125 is passed through the second mounting hole 62, so that one end of the reinforcing lock piece 6 away from the third bolt 115 is mounted on the second support 12. The fourth nut 126 abuts against the side of the reinforcing lock piece 6 away from the second support 12, and the screw head of the fourth bolt 125 abuts against the side of the second support 12 away from the reinforcing lock piece 6, thereby preventing the reinforcing lock piece 6 from detaching from the second support 12. The third bolt 115 and the fourth bolt 125 are respectively passed through the first mounting hole 61 and the second mounting hole 62, restricting the distance between the end of the first support 11 close to the ground and the end of the second support 12 close to the ground.

[0050] Referring to Figure 6 and Figure 7, the reinforcing lock piece 6 has a notch 63, and the notch 63 communicates with the second mounting hole 62, so that when the fourth bolt 125 does not need to rotate the fourth nut 126, it only needs to move from the second mounting hole 62 to the notch 63, and then it can be moved out of the reinforcing lock piece 6. In order to prevent the reinforcing lock piece 6 from rotating around the axis of the third bolt 115 so that the fourth bolt 125 can be rotated out of the reinforcing lock piece 6, a retaining piece 64 is fixedly connected to the inner side wall of the notch 63, that is, unless the distance between the end of the first bracket 11 close to the ground and the end of the second bracket 12 close to the ground is reduced to shorten the distance between the third bolt 115 and the fourth bolt 125, it is impossible to rotate the fourth bolt 125 out of the notch 63.

[0051] The implementation principle of a tripod in an embodiment of the present application is as follows: Pass the first leg 13 through the first bracket 11, pass the first bolt 111 through the first bracket 11 and the corresponding first through hole 1311 in sequence, thread and rotate the first nut 112 on the first bolt 111, then pass the second leg 14 through the second bracket 12, pass the second bolt 121 through the second bracket 12 and the corresponding second through hole 1411 in sequence, thread and rotate the second nut 122 on the first bolt 111, then pass the first wing bolt 511 through the first cross bar 51 and then thread-connect it to the first screw cylinder 114, pass the second wing bolt 521 through the second cross bar 52 and then thread-connect it to the second screw cylinder 124, then rotate the reinforcing lock piece 6 until the fourth bolt 125 enters the second mounting hole 62 from the notch 63, and finally place the bracket group 1 on the ground and adjust the angles of the first bracket 11 and the second bracket 12 so that the front panel 2 and the rear panel 3 are kept horizontal.

[0052] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
