DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Example:

[0044] Please refer to the attached Figure 1 - Attachment Fig.16 The embodiment of the present invention provides an umbrella-type cable test stand, comprising:

[0045] The support mechanism 100 supports the cable to be tested, clamps the cable to be tested, and adapts to the cables to be tested at various heights through telescoping; the leg mechanism 200 is arranged at the upper end of the support mechanism 100, supports the support mechanism 100, and enables the entire support to adapt to more terrains through folding and limiting; the chassis mechanism 300 is arranged at the lower end of the leg mechanism 200;

[0046] The support mechanism 100 can lift the cables that need to be tested, the leg mechanism 200 can be folded to adapt to various terrains, and the chassis mechanism 300 can provide stable support for the leg mechanism 200. In addition, the chassis mechanism 300 is easy to disassemble and convenient to transport.

[0047] Self-locking component 213, which is arranged at the lower end of the leg mechanism 200, stops the rotation of the movable connection of the leg mechanism 200 by limiting the position; self-locking component 230, which is fixedly connected to the middle part of the chassis mechanism 300, makes the disassembly between the chassis mechanism 300 and the leg mechanism 200 easy.

[0048] The self-locking component 1 213 can stop the rotation of the movable connection of the leg mechanism 200 by limiting the position, so as to stabilize the device to support the cable to be tested. The self-locking component 2 330 makes the disassembly between the chassis mechanism 300 and the leg mechanism 200 simple by engaging and self-locking.

[0049] Please refer to the attached Figure 3 - Attachment Figure 4 The leg mechanism 200 includes an upper plate 201, and the outer side of the upper plate 201 is equidistantly and evenly connected to multiple rotating shafts 202, one side of the multiple rotating shafts 202 is rotatably connected to multiple bracket assemblies 210, and one end of the multiple bracket assemblies 210 is threadedly connected to a connecting assembly 320.

[0050] The purpose of the leg mechanism 200 is to support the bracket mechanism 100 and the cable to be tested. The upper plate 201 provides an attachment point for the connection between the bracket mechanism 100 and the leg mechanism 200. The rotating shaft 202 allows the leg mechanism 200 to rotate.

[0052] The rotation of the second rotating rod 211 makes the turning of the first universal joint 212 and the second universal joint 214 more flexible, and the rotation of the first universal joint 212 and the second universal joint 214 ensures high flexibility in folding and rotating the leg mechanism 200. The limiting of the self-locking component 1 213 limits the movable connection between the first universal joint 212 and the second universal joint 214, ensuring that the movable connection is locked, and preventing the first universal joint 212 and the second universal joint 214 from continuing to rotate.

[0053] Please refer to the attached Figure 5 - Attachment Figure 7 The self-locking component 1 213 includes a rotating shaft 4 2131, both ends of the rotating shaft 4 2131 are rotatably connected to the universal joint 1 212, the lower side of the rotating shaft 4 2131 is meshingly connected with a gear 3 2132, a gear 4 2133 is provided on one side of the gear 3 2132, one end of the gear 4 2133 is threadedly connected to a limiting block 2134, a turning handle 2 2135 is provided on one side of the limiting block 2134, the outer side of the limiting block 2134 is slidably connected to the inner wall of the outer shell 2136, and one side of the outer shell 2136 is fixedly connected to the universal joint 1 212.

The rotating shaft 4 2131 ensures the rotation between the universal joint 1 212 and the universal joint 2 214. The gear 3 2132 supports the rotating shaft 4 2131. When the turning handle 2135 is pushed, the gear 4 2133 moves toward the gear 3 2132. When the turning handle 2135 is pushed, the rotating shaft 4 2131 will be limited by the gear 4 2133 because the gear 4 2133 is limited by the turning handle 2135 and the limiting block 2134.

[0064] The rotation axis 5 3301 is a rotating axis. The upward movement of the rotation axis 5 3301 drives the limit rod 3304 to move upward. The limit ring 3303 plays a limiting role, which can allow the limit rod 3304 to slide normally. The limit rod 3304 moves upward, driving the cross bar 3305 to move upward. The upward movement of the cross bar 3305 pulls the support arm 2 3312 to move upward. The support arm 2 3312 moves upward to ensure the rotation of the support arm 1 3311, so that the support arm 1 3311 drives the sliding bar 3307 to move upward, and the sliding bar 3307 drives the arc bracket 3306 to move upward. When the arc bracket 3306 moves upward, it presses the slider 3308, and the spring 3309 under the slider 3308 contracts. When the arc bracket 3306 passes the slider 3308, the spring 3309 rebounds, and the slider 3308 limits the arc bracket 3306 to ensure that the slider 3308 can support the rotation axis 5 3301.

[0067] Working principle: for the entire main body, first, when the specific structural state of the leg mechanism 200 and the bracket mechanism 100 is determined by rotating the universal joint 1 212, the universal joint 214, the shaft 3 202, the rotating rod 211, the rotating shaft 2 111, and the rotating rod 1 112 respectively, the universal joint 1 212 and the universal joint 2 214 are prevented from rotating by twisting and pushing the handle 2 2135 of the self-locking component 1 213. When it is needed to be used on the chassis body 310, the connecting rod 302 is aligned with the self-locking component 2 330 to achieve self-locking.

[0068] For the self-locking component 1 213, first rotate the universal joint 1 212 and the universal joint 214 to the appropriate position, turn the handle 2 2135, the threaded end of the handle 2 2135 will move relative to the limit block 2134, when the gear 4 2133 and the threaded end of the shaft 4 2131 are close to each other, the non-threaded end of the handle 2 2135 is slidingly connected with the limit block 2134, the limit block 2134 next to the handle 2 2135 and the groove on the limit block 2134 together play a limiting role, after limiting, the rotation of the universal joint 1 212 and the universal joint 2 214 is blocked, so that the structure reaches a stable state.

[0069] For the power component 115, turn the handle 1156, so that the handle 1156 rotates to drive the bevel gear 2 1155 to rotate, the bevel gear 2 1155 rotates to drive the bevel gear 1154, the bevel gear 1154 rotates to drive the screw rod 2 1152 to rotate, the screw rod 2 1152 rotates to make the main rod 113 move upward, thereby achieving the purpose of extending the leg mechanism 200.

[0070] For the self-locking component 2 330, the rotating shaft 5 3301 is the rotating shaft. The rotating shaft 5 3301 moves upward to drive the limit rod 3304 to move upward. The limit ring 3303 plays a limiting role, which can allow the limit rod 3304 to slide normally. The limit rod 3304 moves upward to drive the cross bar 3305 to move upward. The cross bar 3305 moves upward to pull the support arm 2 3312 to move upward. The support arm 2 3312 moves upward to ensure the rotation of the support arm 1 3311. , so that arm 1 3311 drives slide bar 3307 to move upward, slide bar 3307 drives arc-shaped bracket 3306 to move upward, arc-shaped bracket 3306 presses slider 3308 when moving upward, spring 3309 under slider 3308 contracts, when arc-shaped bracket 3306 passes slider 3308, spring 3309 rebounds, slider 3308 limits arc-shaped bracket 3306, and ensures that slider 3308 can support rotating shaft five 3301.
