Description

Technical Field

[0001] This utility model relates to the field of pivot door technology, and in particular to a support base for pivot doors. Background Technology

[0002] A hinged door is a door whose leaves rotate around a vertical axis to open and close, and it is one of the important forms of access control. In existing hinged door structures, the base structure used to connect with the bottom of the hinge for rotation is usually fixed in position and cannot be adjusted according to actual installation and usage requirements. This non-adjustable base structure, during actual installation, is prone to problems such as construction errors, asynchronous installation of the top frame and base, and uneven ground, which can easily cause the axes of the top and bottom of the hinge to not be aligned. When the above conditions occur, the door is prone to tilting after installation. A tilted door not only severely affects the aesthetics of the hinged door but also causes it to rotate poorly, increases friction between the door and surrounding structures, accelerates component wear, and shortens the door's lifespan. More importantly, a tilted door may pose safety hazards; for example, it may jam or become stuck during rotation, or even cause collision injuries to pedestrians, failing to meet the safety and reliability requirements for actual use. Summary of the Invention

[0003] The purpose of this utility model is to provide a support base for a pivot door in order to address the defects and shortcomings of the existing technology.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: The present invention discloses a support base for a pivot door, comprising a base plate; a downwardly protruding convex shape is provided on the bottom surface of the base plate; a support seat is slidably connected to the inner cavity of the convex shape; a connecting hole is provided on the top surface of the support seat; and threaded holes are provided on the left and right side walls of the inner cavity of the convex shape. The threaded hole extends at an angle to the top surface of the base plate; the screw is threaded into the threaded hole and then abuts against the support.

[0005] Furthermore, side positioning grooves are provided on both the left and right sides of the support base.

[0006] Furthermore, the base plate has multiple scale lines on its surface; the scale lines are arranged sequentially along the sliding direction of the support; and the support has indicator lines on its surface.

[0007] Furthermore, the base plate has hole groups on both the left and right sides; the hole groups consist of base strip holes and base adjustment strip holes; the length directions of the base adjustment strip holes and the base strip holes are both perpendicular to the sliding direction of the support.

[0008] Furthermore, the base adjustment slot is provided with a countersunk recess; the countersunk recess is a countersunk hole on the top surface of the base plate; the countersunk hole is in the shape of a slot; the length direction of the countersunk hole is perpendicular to the length direction of the base adjustment slot; an eccentric block is provided inside the countersunk hole; the eccentric block is circular; the diameter of the eccentric block is equal to the width of the countersunk hole; a countersunk hole is provided at the eccentric position of the eccentric block; a handle hole is provided at the eccentric position of the eccentric block.

[0009] Furthermore, the handle hole is a regular hexagonal hole.

[0010] Furthermore, a baffle strip is provided around the side wall of the base plate; A decorative cover is snapped onto the top surface of the base plate; the decorative cover consists of two cover plates; a downward protruding flange is provided on the edge of the cover plate; a buckle is provided on the flange; after the flange is fitted onto the outside of the base plate, the buckle snaps into the bottom surface of the baffle.

[0011] With the above structure, the beneficial effects of this utility model are as follows: the base plate is fixed on the ground, the bottom of the door's pivot is inserted into the connecting hole for positioning, and the support seat is pushed to slide in the convex inner hole by the tightening and loosening of the bolts in the threaded holes on both sides, so as to finely adjust the lateral position of the door's pivot on the base plate, reduce the installation difficulty, and increase the stability of the door in use.

The inside of the convex shape 103 is provided with a guide groove 10301, and a guide strip 304 matching the guide groove 10301 is provided on the bottom surface of the support 3. The base plate 1 is fixed on the ground. The bottom of the door's pivot is inserted into the connecting hole 302 for positioning. The support seat 3 is pushed to slide in the inner hole of the convex shape 103 by the tightening and loosening of the bolts in the threaded holes 102 on both sides. This allows for fine adjustment of the lateral position of the door's pivot on the base plate 1, reducing installation difficulty and increasing the stability of the door.

[0015] As a preferred embodiment of this utility model, the support base 3 is provided with side positioning grooves 301 on both the left and right sides; the end of the bolt is set in a conical shape, and then the conical part of the bolt is inserted into the side positioning groove 301 to prevent the bolt from sliding on the surface of the support base 3.

Therefore, when drilling holes in the ground, the holes need to be larger than the convex shape 103 to ensure that the ground does not interfere with the convex shape during longitudinal adjustment. Furthermore, after the support base is assembled, only the base plate protrudes from the ground, making the overall thickness of the support base protruding from the ground thinner.

[0018] In a preferred embodiment of this utility model, the base adjustment slot 10401 is provided with a countersunk recess; the countersunk recess is a base countersunk hole 104 provided on the top surface of the base plate 1; the base countersunk hole 104 is in the shape of a slot; the length direction of the base countersunk hole 104 is perpendicular to the length direction of the base adjustment slot 10401; an eccentric block 2 is provided inside the base countersunk hole 104; the eccentric block 2 is circular; the diameter of the eccentric block 2 is equal to the width of the base countersunk hole 104; a countersunk hole 201 is provided at the eccentric position of the eccentric block 2; a handle hole 202 is provided at the eccentric position of the eccentric block 2. After the bolt passes through the countersunk hole 201 and the base adjustment strip hole 10401, it is threaded onto the embedded part in the ground. After loosening the bolt, the eccentric block 2 is rotated by inserting the handle into the handle hole 202, which can more accurately adjust the base plate 1 longitudinally along the ground. After adjustment, the eccentric block 2 is locked with the expansion lock to increase the stability of the door leaf.
