[0020] like Figures 1 to 4 As shown, the utility model is an adjustable metal protection net, comprising: a column 1, a base 2, a metal protection net 3, and an adjustment structure 4 for adjusting the height of the metal protection net 3.

[0021] The column 1 is composed of a first column 11 and a second column 12 installed on the first column 11 and movable up and down. A groove 112 is provided in the first column 11, and the width of the groove 112 is greater than the width of the second column 12. The groove 112 can play a certain limiting role on the second column 12 that moves up and down, avoiding it from shaking left and right when moving up and down. The metal protective mesh 3 is fixed to the second column 12 by a fixing member 13, and the fixing member 13 is preferably a metal wire. A limiting groove 111 is provided on the side of the first column 11, and the width of the limiting groove 111 is greater than the thickness of the metal protective mesh 3. The limiting groove 111 is used to limit the metal protective mesh 3 to improve its stability when moving up and down.

[0022] The adjustment structure 4 includes: a rotatable reel 41 installed in the base 2, the metal protective mesh 3 is rolled up on the reel 41, a handle 42 coaxially mounted with the reel 41, a main gear 43 installed on the reel 41, two main gears 43 are provided, located at the left and right ends of the main gear 43, a driven gear 44 meshing with the main gear 43, a screw 45 coaxially mounted with the driven gear 44, and a movable block 46 threadedly connected to the screw 45, the movable block 46 is fixedly connected to the second column 12, and a groove body is provided on the inner wall of the groove 112 to limit the deflection of the movable block 46.

[0023] In the present utility model, by turning the handle 42, the handle 42 rotates forward, the reel 41 drives the main gear 43 to rotate, drives the driven gear 44 to rotate, and the screw 45 rotates. Due to the threaded connection, the movable block 46 drives the second column 12 to move upward. During the movement, the reel 41 unwinds the metal protective mesh 3, and the second column 12 drives the metal protective mesh 3 to move upward, thereby achieving the purpose of raising the metal protective net. The handle 42 is reversed, the movable block 46 drives the second column 12 to move upward, the reel 41 rewinds the metal protective mesh 3, and the second column 12 drives the metal protective mesh 3 to move downward, thereby achieving the purpose of lowering the metal protective net.

[0024] The fastening structure 5 is installed on the first column 11. The fastening structure 5 is composed of an adjusting screw rod 51 and a fastener 52. The fastener 52 is preferably a splint with anti-slip grooves installed on the inner wall.

[0025] In the present invention, after the metal protective mesh is adjusted to a suitable height position, the adjusting screw 51 is rotated, and the fasteners 52 move toward each other to clamp the metal protective mesh 3, which can fix it and improve its stability during use. The anti-slip grooves on the inner wall of the fasteners 52 can increase the friction with the metal protective mesh 3 and improve its clamping effect.

[0026] Working principle: Turn the handle 42, the reel 41 drives the main gear 43 to rotate, drives the driven gear 44 to rotate, the screw 45 rotates, and the movable block 46 drives the second column 12 to move up and down. During the movement, the second column 12 drives the metal protective mesh 3 to move up and down, so as to achieve the purpose of quickly adjusting the height of the metal protective mesh to meet different needs. After adjusting to the appropriate height position, turn the adjusting screw 51, and the fasteners 52 move toward each other to clamp the metal protective mesh 3, which can fix it and improve its stability during use.

[0027] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology. It will not be described in detail here. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.
