The drop hammer impact tester simulates external impact loads to evaluate the material's ability to resist damage when subjected to sudden impact.

[0003] However, most existing drop hammer impact testing machines place the pipes on a single fixed base when testing them. This fixing method results in weak stability and a tendency for slippage. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for testing the impact resistance of PE pipes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The main frame has a lifting unit located directly below the drop hammer unit. The main frame has a fixed base arranged through the lifting unit, and the top of the fixed base has a V-shaped groove.

[0008] Furthermore, in a preferred configuration, the limiting assembly includes two limiting blocks, which are symmetrically installed on both sides of one end of the outer wall of the extension tube, and a fixing screw is installed on one side of each limiting block, with a nut screwed onto the outside of the fixing screw.

[0009] In addition, a preferred structure is that a limiting protrusion ring is fixedly sleeved on the bottom end of the extension tube, a through hole is opened in the pressing block at the limiting insertion block, and a locking cavity is opened in the pressing block at the limiting protrusion ring.

[0010] In addition, a preferred structure is that the top center of the fixed base has a groove at the extension tube and the two pressing blocks, and a limit plate is installed on one side of the fixed base.

[0011] In addition, a preferred structure is that the auxiliary pressing component includes a fixed base, an auxiliary pressing block is screwed to the bottom of the fixed base, and a V-shaped clamping groove is provided at the bottom of the auxiliary pressing block.

[0012] In addition, a preferred structure is that an auxiliary screw is fixedly installed at the center of the top of the auxiliary pressing block, and a threaded groove is opened at the bottom of the fixing seat at the auxiliary screw, and the threaded groove is threadedly connected to the auxiliary screw.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this invention, by symmetrically arranging pressure blocks on both sides of the extension tube of the impact resistance testing device, and with the setting of a fixed base and auxiliary pressure components, PE pipes of different diameters within a certain range can be clamped, and the stability of the pipes after clamping can be ensured. At the same time, the pressure blocks and auxiliary pressure blocks are detachable and can be disassembled and replaced after a period of use. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4A device for testing the impact resistance performance of PE pipes includes a device body 1. The device body 1 includes a main frame. A drop hammer unit is provided at the top of the main frame. An extension pipe 4 is provided inside the main frame at the drop hammer unit. Limiting components 41 are symmetrically arranged on both sides of the extension pipe 4. Two symmetrically arranged pressing blocks 5 are inserted into both sides of the extension pipe 4 through the limiting components 41. The bottom of the pressing blocks 5 is provided with an inclined surface facing the extension pipe 4.

[0022] It is worth noting that the specific structure, connection method and working principle of the impact resistance testing device body 1, the drop hammer unit and the lifting unit 2 are all existing technologies that are currently publicly available on the market, and are not the main technical problems to be solved in this utility model. Therefore, this utility model will not elaborate on them.

[0023] Meanwhile, auxiliary pressing components 6 are symmetrically arranged on both sides of the extension tube 4 at the top of the main frame, and a lifting unit 2 is arranged directly below the drop hammer unit in the main frame. A fixed base 3 is arranged in the main frame through the lifting unit 2, and a V-shaped groove is provided on the top of the fixed base 3.

[0024] Meanwhile, the limiting component 41 includes two limiting blocks 411, which are symmetrically installed on both sides of one end of the outer wall of the extension tube 4, and a fixing screw 412 is installed on one side of the limiting block 411, with a nut screwed onto the outside of the fixing screw 412.

[0025] Furthermore, a limiting protrusion ring 42 is fixedly sleeved on the bottom of the extension tube 4, a through hole is opened in the pressing block 5 at the limiting insertion block 411, and a locking cavity is opened in the pressing block 5 at the limiting protrusion ring 42.

[0026] Furthermore, a groove 32 is provided at the top center of the fixed base 3, at the extension tube 4 and the two pressing blocks 5, and a limit plate 31 is installed on one side of the fixed base 3.

[0027] Furthermore, the auxiliary pressing component 6 includes a fixed base 61, and an auxiliary pressing block 62 is screwed to the bottom of the fixed base 61. The bottom of the auxiliary pressing block 62 is provided with a V-shaped clamping groove.

[0028] Furthermore, an auxiliary screw is fixedly installed at the top center of the auxiliary pressing block 62, and a threaded groove is opened at the bottom of the fixing seat 61 at the auxiliary screw, and the threaded groove is threadedly connected to the auxiliary screw.

[0029] It is worth noting that rubber pads are provided on the side of the limiting plate 31 near the extension tube 4, the V-shaped clamping groove of the auxiliary pressing block 62, the V-shaped groove of the fixed base 3, and the inclined surface of the pressing block 5. The rubber pads enhance the stability of clamping the PE pipe and prevent damage to the PE pipe during clamping.

[0030] In this embodiment, by symmetrically arranging the pressure blocks 5 on both sides of the extension tube 4 of the impact resistance testing device, together with the fixed base 3 and the auxiliary pressure assembly 6, PE pipes of different diameters within a certain range can be clamped, and the stability of the pipes after clamping can be ensured. At the same time, the pressure blocks 5 and the auxiliary pressure blocks 62 are detachable and can be disassembled and replaced after a period of use.

[0031] By placing the PE pipe to be tested in the V-shaped groove of the fixed base 3 and making one side of the PE pipe fit against the limiting plate 31, the fixed base 3 and the placed PE pipe are then driven by the lifting unit 2 to move towards the extension pipe 4 until the inclined surface of the pressing block 5 fits against the outer wall of the PE pipe, thereby limiting and clamping the PE pipe to ensure its stability. Furthermore, by setting two sets of auxiliary pressing components 6, the two sides of the extension pipe 4 of the PE pipe are further pressed to further ensure the stability of the PE pipe after clamping.

[0032] In this utility model, by symmetrically arranging the pressure blocks 5 on both sides of the extension tube 4 of the impact resistance testing device, together with the fixed base 3 and the auxiliary pressure component 6, PE pipes of different diameters within a certain range can be clamped, and the stability of the pipes after clamping can be ensured. At the same time, the pressure blocks 5 and the auxiliary pressure blocks 62 are detachable and can be disassembled and replaced after a period of use.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
