Description

Technical Field

[0001] The utility model belongs to the technical field of curtain wall hardware and relates to a rear drag sliding support. Background Art

[0002] The rear sliding support for doors and windows is a support device for doors and windows. Its main function is to provide support when the doors and windows are opened, so that they can stay in any position, which is convenient for users to perform ventilation, lighting and other operations. It is usually installed on the top or side of the door or window, and the position of the support rod is adjusted by sliding or rotating to meet the needs of different heights and angles. The rear sliding support has the characteristics of simple structure, easy use, safety and reliability, and is widely used in doors and windows in homes, offices, businesses and other places. However, the types of sliding supports on the market are single in appearance, and the load-bearing capacity does not meet the ideal requirements. Usually, thinner aluminum strips are used to form the support, which will cause rotation blockage after long-term use. Therefore, it is not very practical and has poor aesthetics. Utility Model Content

[0006] In the above-mentioned rear drag slide, one end of the slide rod and the positioning rod are connected to a side plate, and are arranged as a 90-degree vertical integrated structure, wherein the side plate of the slide rod is provided with a slot.

[0007] In the above-mentioned rear drag sliding support, a No. 2 clamping block is screwed and connected to the side plate of the positioning rod through a hexagon socket head screw, and a protruding clamping block is arranged below the hexagon socket head screw and is inserted and connected in the clamping slot.

[0008] In the above-mentioned rear drag slide, three fixed installation holes are evenly opened on the slide rod, a movable groove is opened through one end of the slide rod, and the No. 3 rivet passes through the long connecting rod, the pad and the movable groove to be fixedly connected with the slide block.

[0009] In the above-mentioned rear drag sliding support, the top surface of the sliding block is closely connected to the bottom of the sliding rod, and a cross recessed countersunk screw is screwed and connected between the other end of the sliding block and the cushion block.

[0010] In the above-mentioned rear drag sliding support, a limiting groove is provided on one side of the gasket, wherein the limiting groove is arranged as an open groove structure and is arranged in an inclined manner.

[0011] In the above-mentioned rear drag slide, a limiting block is inserted into the limiting groove, wherein the limiting block is a semicircular protrusion structure and is fixedly connected to the inner wall of the slide rod, and two groups of semicircular support blocks are also arranged on the bottom of the slide rod.

[0012] In the above-mentioned rear drag slide, washers are sleeved on the No. 2 rivet, the No. 3 rivet and the No. 4 rivet, wherein the thickness of the washers in the No. 4 rivet is not less than the thickness of the washers in the No. 2 rivet and the No. 3 rivet.

[0013] In the above-mentioned rear drag sliding support, one end of the short connecting rod is set as a Z-shaped structure, and the long connecting rod is a stepped structure. A groove is set on the positioning rod, and the bottom of the groove is fitted and connected to the end surface of one end of the short connecting rod and the long connecting rod.

[0014] In the above-mentioned rear drag slide, the pad is configured as a sports car-style plastic block, wherein the widths of the slide bar, gasket, short connecting rod, middle connecting rod, long connecting rod and pad are consistent.

[0015] Compared with the existing technology, the advantages of the utility model are:

[0016] The utility model is different from the rear tow slide supports on the market. Firstly, a right-angle bend integrated structure is adopted at the slide rod head, and a side panel is provided.
