[0003] The first technical problem to be solved by the present invention is to provide an assembling connector which is easy to install and can reduce material costs.
[0004] In order to solve the first technical problem mentioned above, the technical solution adopted by the present invention is: an assembly connector for a hollow elevator guide rail, comprising: a connecting base plate, a reinforcing positioning block corresponding to the gap between a pair of guide rail edges of the hollow elevator guide rail is provided in the middle of the connecting base plate, and two groups of mounting threaded holes are provided on the connecting base plate along its length direction, and each group of mounting threaded holes includes at least two mounting threaded holes.
[0005] As a preferred solution, in the assembly connector of the hollow elevator guide rail, the reinforced positioning block is set on the connecting base plate by welding, and the specific setting method is: the reinforced positioning block is respectively provided with longitudinal welding points between the connecting base plate and the connecting base plate on both sides in the length direction.
[0006] As a preferred solution, in the assembly connector of the hollow elevator guide rail, the reinforcement positioning block is respectively provided with at least one transverse welding point between the connecting base plate and both sides in the width direction of the connecting base plate.
[0007] As a preferred solution, in the assembly connector of the hollow elevator guide rail, at least one of the transverse welding points on the same side is arranged in the middle of the reinforced positioning block.
[0008] As a preferred solution, in the assembly connector of the hollow elevator guide rail, each group of mounting threaded holes includes four mounting threaded holes.
[0009] As a preferred solution, in the assembly connector of the hollow elevator guide rail, an avoidance groove arranged along the length direction of the connecting base plate is opened on the bottom surface of the connecting base plate.
[0010] The beneficial effects of the utility model are:
[0011] 1. By adopting the one assembling connector described in the utility model, adjacent hollow elevator guide rails can be assembled, and three connectors are no longer needed to assemble the hollow elevator guide rails, which greatly facilitates the installation of the hollow elevator guide rails and reduces material costs and installation costs. In addition, the assembling connector described in the utility model has higher strength.
[0012] 2. The utility model fixes the reinforcing positioning block to the connecting base plate by welding, which greatly reduces the manufacturing cost.
[0013] 3. The utility model greatly increases the overall strength of the connecting base plate and strengthens the overall bending coefficient of the connecting base plate by arranging longitudinal welding points between the reinforcing positioning blocks on both sides of the connecting base plate in the length direction, making the hollow elevator guide rail smoother.
[0014] 4. The utility model provides an avoidance groove arranged along the length direction of the connecting base plate on the bottom surface of the connecting base plate, so that even if there is a protrusion on the weld on the hollow elevator guide rail, the assembled connecting piece can be tightly attached to the hollow elevator guide rail without affecting the normal installation of the assembled connecting piece and the hollow elevator guide rail.
