The spacing groove is used for preventing ending the carousel and taking place to interfere with interior slideway, strengthens the structural strength that the bump is favorable to strengthening this department, and the breach groove is as the technology mouth, and stamping equipment can get into by breach groove department, carries out the punching press around the spacing groove to form and strengthen the bump.
In the scheme, the method comprises the following steps: the rear end bottom both sides of reducing gear box are provided with the arch, correspond bellied position department in the front end bottom both sides of slide rail and are equipped with the mounting groove including, the reducing gear box passes through the arch card in the mounting groove. Traditional reducing gear box need just can block in the mounting groove with the help of the connecting piece, and this structure is direct to form the arch in the both sides of reducing gear box, blocks in the mounting groove through the arch, simple structure, simple to operate.
In the scheme, the method comprises the following steps: the arched bulge is arranged at the position, close to the rear, of the middle of the top surface of the rear end part of the reduction gearbox. The arched bulge is positioned in the middle position to better protect the bolt hole, and the rear part is provided with a structure which is beneficial to increasing the edge of the reduction gearbox.
The utility model has the advantages that:
1. the rear end part of the reduction gearbox extends into an inner cavity formed by the inner slide rail and the outer slide rail and is fixedly connected with the inner slide rail, the top surface of the rear end of the reduction gearbox is locally sunk to reduce the overall height of the rear end of the reduction gearbox, a hollow groove matched with the arched bulge and the top of the rotation stopping disc is formed in the top surface of the inner slide rail, the height space required by installation of the reduction gearbox and the rotation stopping disc is effectively reduced by embedding the arched bulge and the top of the rotation stopping disc in the hollow groove, and the installation of the reduction gearbox and the seat slide rail under the limitation of the installation height is realized.
2. The rear end of the reduction box is provided with a screw rod mounting hole for mounting a screw rod, and the height space from the screw rod mounting hole to the top surface of the rear end part of the reduction box is smaller due to the smaller height of the section of the slide rail, the pin hole can only be arranged by being attached to the top surface of the rear end part of the reduction box, and the wall thickness of the top surface of the pin hole is thinner, usually only 1-2 mm, so that the screw rod mounting hole is very easy to damage; this mounting structure has reserved an arch at the rear end top surface of reducing gear box, has effectively increased the top surface wall thickness in bolt hole, has guaranteed the structural strength of this position department to avoid the bolt hole to be damaged easily.
