Description

Technical Field

[0001] The utility model belongs to the field of interlocking doors, and particularly relates to an upper wheel for a ground rail installed on the top of a door body. Background Art

[0002] The upper wheel of an interlocking door is installed in a profile groove at the top of the door body and slides along the side wall of the profile groove through a pulley to prevent the door body from swinging back and forth during the sliding process. The existing upper wheels generally install the base in the profile groove by clamping the rotating pieces on the base into the notches on both sides of the profile groove, or directly fixing the base to the profile groove by screwing. During the sliding process of the door body, the pulley continuously presses the side wall of the profile groove, and the lateral shear force received by the base increases. However, these installation methods are likely to cause the base to deform and become loose, so a reliable base installation structure is needed. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an upper wheel for a ground rail to make the installation of the mounting seat and the profile groove more firm.

[0004] An upper wheel for a ground rail includes a mounting seat. The mounting seat is provided with a first pulley and a second pulley parallel to it. The connection line of the first pulley and the second pulley deviates from the length direction of the mounting seat. Convex strips are provided on both sides of the mounting seat. A retaining platform is provided on one end face of the convex strip. An inclined insertion hole is provided between the convex strips, and the insertion hole communicates with the bottom surface of the mounting seat.

[0005] An adjusting frame and a sliding plate are provided on the top surface of the mounting seat. The adjusting frame and the sliding plate are connected by bolts arranged along the length direction of the mounting seat. The sliding plate installs the first pulley and the second pulley through a connecting plate, and the heights of the first pulley and the second pulley relative to the mounting seat are the same.

[0006] The adjusting frame and the sliding plate extend out from the top surface of the mounting seat and form a slot with the convex strip.

[0007] The sliding plate is provided with a longitudinal groove, and the sliding plate is inserted into the mounting seat through a limit pin passing through the longitudinal groove.

[0008] The sliding plate is provided with a first inclined groove and a second inclined groove. The connecting plate is installed in the first inclined groove through a first limit post, and the connecting plate is installed in the second inclined groove through a second limit post.

[0009] A buffer baffle is installed on one side of the adjusting frame.

[0010] The beneficial effect of the utility model is that the mounting seat is inserted into both sides of the profile groove through the convex strip, increasing the installation surface between the mounting seat and the profile groove. The retaining platform is used to hook the end face of the profile groove, and then the mounting seat is fixed to the profile groove through a screw passing through the insertion hole. This installation structure is stable and firm. Description of the Drawings

[0012] Figure 2 is Figure 1 exploded view. Specific implementation manner

[0013] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0014] As Figure 1 , 2 shown, the upper wheel of the ground rail is based on the mounting seat 1. The two sides of the mounting seat 1 are stepped to form convex strips 2. A retaining platform 3 is provided at one end face of each convex strip 2, and an inclined block is provided at the other end. The inclined block facilitates the insertion of the entrance into the profile groove. An inclined jack 4 is provided along the bottom surface of the mounting seat 1 from one side of the retaining platform 3, and the jack 4 is exposed from the bottom surface of the mounting seat 1.

[0015] The top surface of the mounting seat 1 is provided with an adjusting frame 5 and a sliding plate 6. The two sides of the adjusting frame 5 and the two sides of the sliding plate 6 protrude from the top surface of the mounting seat. The protruding part forms a slot 7 with the step of the mounting seat. The adjusting frame 5 is provided with an L-shaped bending plate, and the sliding plate 6 is also provided with an L-shaped bending plate. The adjusting frame 5 and the sliding plate 6 are arranged in sequence along the length direction of the mounting seat 1 from one side of the retaining platform 3. The L-shaped bending plate of the adjusting frame 5 is close to one side of the retaining platform 3. The tail of the adjusting frame 5 corresponds to the L-shaped bending plate of the sliding plate 6. The two ends of the sliding plate 6 are respectively installed with a first pulley 9 and a second pulley 10 through a connecting plate 8. The L-shaped bending plates of the adjusting frame 5 and the sliding plate 6 are connected by bolts 11. A buffer baffle 12 is fixed by screws on one side of the adjusting frame 5. The buffer baffle is used in cooperation with the buffer hook arranged at the top of the door frame to slow down the closing speed of the door leaf.

[0016] When the upper wheel of the ground rail is installed on the profile at the top of the door body, the mounting seat 1 is inserted into both sides of the profile groove through the convex strips 2, and the slot 7 is inserted into the rib of the side wall of the profile groove, thereby increasing the installation surface between the mounting seat and the profile groove. And the retaining platform 3 is used to hook the end face of the profile groove, and then the mounting seat is fixed to the bottom surface of the profile groove through the screw passing through the jack 4, forming four fixing surfaces of the convex strip, the slot, the jack and the hook platform, ensuring the structural firmness of the mounting seat.

[0017] The first pulley 9 and the second pulley 10 are installed at the same height and are parallel to the mounting base 1, and the connection line of the first pulley 9 and the second pulley 10 deviates from the length direction of the mounting base 1. The connecting plate 8 is installed on the first inclined groove 14 of the sliding plate 6 through the first limiting post 13, and the connecting plate 8 is installed on the second inclined groove 16 of the sliding plate 6 through the second limiting post 15. The sliding plate 6 is provided with a limiting nail 18 inserted into the mounting base 1 through a longitudinal groove 17. By turning the bolt 11, the sliding plate 6 moves along the limiting nail 18. At the same time, the sliding plate 6 pushes the first limiting post 13 to move through the first inclined groove 14 and pushes the second limiting post 15 to move through the second inclined groove 16, so that the connecting plate 8 rotates relative to the sliding plate 6, thereby enabling the first pulley 9 and the second pulley 10 to match the width of the profile groove.
