Description

Technical Field

[0001] The utility model relates to a connection structure, in particular to a connection structure of a guide column and a fixed flange. Background Art

[0002] The current connection method between the guide column and the fixed flange is mainly to drill a pin hole in the middle of the threaded connection between the guide column 1 and the flange 2, and insert the pin to fix it, and then fix the flange 2 in a suitable place with a fixing bolt; this connection guide column is prone to breakage at the drilling position; a slot is made at the tail of the guide column, the flange is made into two semicircular shapes, the flange is inserted into the guide column slot, and then the flange is fixed in a suitable place with a fixing bolt. This connection guide column is prone to breakage at the slot position; therefore, it is necessary to design a connection method that can be disassembled and has high connection strength. Utility Model Content

[0003] The utility model aims to provide a connecting structure between a guide column and a fixing flange.

[0004] Based on the above purpose, the utility model adopts the following technical solutions:

[0005] A connection structure between a guide column and a fixed flange comprises a guide column, a flange and fixing bolts. The right end of the guide column is provided with an external thread, the flange is provided with an internal thread, the guide column and the flange are threadedly connected, the overlapping ends of the guide column and the flange threaded connection are provided with a positioning groove, a positioning block is installed in the positioning groove to prevent the external thread of the guide column and the internal thread of the flange from disengaging after rotating to the matching limit position, and the flange is installed on the required equipment body through fixing bolts.

[0006] Furthermore, the length of the positioning groove runs through the guide column and extends up and down or left and right to the flange by 3 mm each.

[0007] The utility model can also be used for the fixed connection of a screw, a pin shaft and a flange, solving the problem that the existing connection mode of the guide column, the screw and the pin shaft and the fixed flange has low connection strength and is easy to break. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a cross-sectional view of the utility model;

[0009] Figure 2 for Figure 1 Right view of;

[0010] In the figure: 1. guide column, 2. flange, 3. positioning block, 4. fixing bolt, 5. positioning groove. DETAILED DESCRIPTION

[0011] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0012] Example 1

[0013] A connecting structure between a guide column and a fixed flange, such as Figure 1 and 2 As shown, it includes a guide column 1, a flange 2, and a fixing bolt 4. The right end of the guide column 1 is provided with an external thread, the flange 2 is provided with an internal thread, the guide column 1 and the flange 2 are threadedly connected, and the overlapping ends of the guide column 1 and the flange 2 where the threads are connected are provided with a positioning groove 5. The positioning groove 5 is provided with a positioning block 3 for preventing the external thread of the guide column 1 and the internal thread of the flange 2 from rotating to the matching limit position and then disengaging. The flange 2 is installed on the required equipment body through the fixing bolt 4.

[0014] Furthermore, the length of the positioning groove 5 penetrates the guide column 1 and extends up and down or left and right to the flange 2 by 3 mm each.

[0015] The above description is only a partial implementation mode of the present utility model. For ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the principle of the present utility model. These improvements and substitutions should also be regarded as the protection scope of the present utility model.
