Detailed Description

Referring to fig. 1-4, the present invention provides a technical solution: a bending-resistant straight rail groove comprises a pre-buried channel 1 and T-shaped bolts 2, wherein an inner groove 4 in a T shape is formed in the bottom of the pre-buried channel 1, the T-shaped bolts 2 are transversely arranged at the bottom of the pre-buried channel 1, the front side and the rear side of the upper end of the pre-buried channel 1 and the left side and the right side of the upper end of each T-shaped bolt 2 are inclined planes, two anchor legs 3 are fixedly connected to the upper end of the pre-buried channel 1, two bolt grooves 7 are formed in the upper end of the pre-buried channel 1 and between the two anchor legs 3, and fixing holes 6 penetrating through the inner groove 4 are formed in the bottoms of the bolt grooves 7;

when the embedded channel 1 is poured into concrete, a bolt penetrates through the fixing hole 6 from the bottom, a nut is used at the upper end of the embedded channel 1 and is sleeved on the bolt, when the bolt is screwed down, the nut can be inserted into the bolt groove 7 and is limited, so that the bolt does not need to be rotated, and the nut is limited to rotate, so that the embedded channel 1 can be conveniently fixed in a pouring mold, two anchor legs 3 at the upper end of the embedded channel 1 enable the embedded channel 1 to be more firmly fixed on a concrete wall after the concrete is solidified, and in addition, the front side and the rear side of the upper end of the embedded channel 1 are inclined planes, so that the strength of the embedded channel 1 can be enhanced, and the embedded channel 1 is more resistant to bending;

four corners of the upper end of the inner wall of the inner groove 4 are fixedly connected with fixing blocks 5, limiting rods 12 are fixedly connected to the inner sides of the fixing blocks 5, torsion springs 11 are sleeved outside the limiting rods 12, push-pull strips 10 are arranged between the front sides of the two fixing blocks 5 at the rear end and between the rear ends of the two fixing blocks 5 at the front end, clamping strips 9 are arranged between the lower ends of the two fixing blocks 5 at the rear end and between the lower ends of the two fixing blocks 5 at the front end, clamping grooves 8 are formed in the left side and the right side of each T-shaped bolt 2, the left side and the right side of each push-pull strip 10 are fixedly connected with the front ends of the two adjacent torsion springs 11, the left side and the right side of each clamping strip 9 are fixedly connected with the lower ends of the two adjacent torsion springs 11, and the initial angle of each torsion spring 11 is ninety degrees;

when installing the davit on the rail groove, at first insert T type bolt 2 in inside groove 4, rotate ninety degrees T type bolt 2 afterwards, make the left and right sides of T type bolt 2 rotate the position of card strip 9, T type bolt 2 upper end inclined plane will extrude the push-pull strip 10 like this, make push-pull strip 10 use gag lever post 12 to overturn from top to bottom as the center, can drive torsion spring 11 and card strip 9 like this and follow push-pull strip 10 and upwards overturn, make card strip 9 remove to the draw-in groove 8 in, because torsion spring initial angle is ninety degrees, when push-pull strip 10 is extrudeed, torsion spring 11 can take place the deformation, from this point of making card strip 9 to the inside extrusion of draw-in groove 8, T type bolt 2 will be held by card strip 9 like this, when installing the davit, T type bolt 2 just is difficult to the off normal, make things convenient for the staff to install the davit.

The working principle is as follows: when the pre-buried channel 1 is poured into concrete, a bolt penetrates through the fixing hole 6 from the bottom, a nut is used at the upper end of the pre-buried channel 1, the nut is sleeved on the bolt, when the bolt is tightened, the nut can be inserted into the bolt groove 7, the nut is limited, after the concrete is solidified, the pre-buried channel 1 is more firmly fixed on the concrete wall after the two anchor legs 3 at the upper end of the pre-buried channel 1, when the T-shaped bolt 2 is installed, the T-shaped bolt 2 is inserted into the inner groove 4, then the T-shaped bolt 2 is rotated by ninety degrees, the left side and the right side of the T-shaped bolt 2 are rotated to the position of the clamping strip 9, the inclined plane at the upper end of the T-shaped bolt 2 can extrude the pushing and pulling strip 10, the pushing and pulling strip 10 is turned over up and down by taking the limiting rod 12 as the center, the torsion spring 11 and the clamping strip 9 are driven to be turned over upwards along with the pushing and the clamping strip 10, and the clamping strip 9 is moved into the clamping groove 8, because torsion spring initial angle is ninety degrees, when push-pull strip 10 was extruded, torsion spring 11 can take place deformation, makes card strip 9 extrude to draw-in groove 8 inside from this point on, and T type bolt 2 will be held by card strip 9 like this, accomplishes the installation of T type bolt 2.
