Technical Field

[0001] This utility model relates to the field of universal testing machine technology, and in particular to an auxiliary device for a universal testing machine. Background Technology

[0002] The universal mechanical testing machine is a material testing machine that integrates functions such as tension, bending, compression, shear, and ring stiffness testing. It is mainly used for mechanical property testing of metallic and non-metallic materials.

[0003] Universal testing machines are prone to material breakage and splashing during testing, so auxiliary equipment needs to be installed on the universal testing machine for safety protection.

[0004] Currently, most auxiliary equipment uses protective plates for protection. However, existing protective plates have the following problems: they are large in size and do not have a self-folding function, which results in them taking up a lot of space when stored and being inconvenient to carry. Therefore, an auxiliary device for a universal mechanical testing machine is proposed. Utility Model Content

[0010] An upper mounting block and a lower mounting block are provided. The upper mounting block is fixedly installed on the upper end of the second protective plate, and the lower mounting block is fixedly installed on the lower end of the first protective plate. L-shaped mounting rods are fixedly installed on both the left and right ends of the upper and lower mounting blocks.

[0011] The mounting side block is fixedly installed on the other end of the L-shaped mounting rod. A horizontally arranged positioning screw is threaded through the mounting side block, and a positioning head is rotatably installed on the end of the positioning screw near the second protective plate.

Therefore, they should not be construed as limitations on this utility model.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0042] like Figure 1-3 As shown, this utility model embodiment provides an auxiliary device for a universal testing machine, including a first protective plate 1, a second protective plate 11, an upper mounting block 9, a lower mounting block 12, and a mounting side block 7. The upper end of the first protective plate 1 has a slot 14, and the bottom of the second protective plate 11 is inserted into the slot 14. The upper mounting block 9 is fixedly installed on the upper end of the second protective plate 11, and the lower mounting block 12 is fixedly installed on the lower end of the first protective plate 1. L-shaped mounting rods 5 are fixedly installed on both the left and right ends of the upper mounting block 9 and the lower mounting block 12. The mounting side block 7 is fixedly installed on the other end of the L-shaped mounting rod 5. A horizontally arranged positioning screw 6 is threaded through the mounting side block 7, and a positioning head 8 is rotatably installed on the end of the positioning screw 6 near the second protective plate 11.

[0043] During installation, the first protective plate 1 and the second protective plate 11 can be placed in front of the universal testing machine, and the two positioning heads 8 on the upper mounting block 9 can be placed on the left and right sides of the universal testing machine. At the same time, the two positioning heads 8 on the lower mounting block 12 can be placed on the left and right sides of the universal testing machine. The horizontal position of the positioning heads 8 can be adjusted by twisting the positioning screw 6, so that the two positioning heads 8 on the upper mounting block 9 clamp and position the universal testing machine, and the two positioning heads 8 on the lower mounting block 12 clamp and position the universal testing machine, thereby achieving the fixation between the first protective plate 1 and the second protective plate 11 and the universal testing machine.

[0044] In this embodiment, a transparent observation window 10 is also included. The transparent observation window 10 is installed on the second protective plate 11, and the material of the transparent observation window 10 is explosion-proof glass.

[0045] Through the transparent observation window 10, staff can observe the working process of the universal testing machine through the second protective plate 11.

[0046] The positioning head 8 is equipped with anti-slip texture.

[0047] By setting anti-slip textures, the friction between the positioning head 8 and the universal testing machine can be increased, thereby improving the positioning effect of the positioning head 8.

[0048] It also includes side openings and racks 4. There are two side openings, which are symmetrically opened at the top left and right ends of the first protective plate 1 and are connected to the slots 14. There are two racks 4, which are symmetrically embedded and fixedly installed at the left and right ends of the second protective plate 11. The racks 4 are set in the vertical direction.

[0049] It also includes positioning components 2, of which there are two, and the two positioning components 2 are symmetrically installed on the left and right ends of the first protective plate 1.

[0050] like Figure 2-4 As shown, the positioning component 2 also includes a C-shaped mounting plate 201, an adjusting screw 202, and a gear 204. The C-shaped mounting plate 201 is fixedly installed on the top side of the first protective plate 1. The rear end of the adjusting screw 202 is rotatably connected to the inner rear end face of the C-shaped mounting plate 201. The front end of the adjusting screw 202 passes through the front end of the C-shaped mounting plate 201 and extends to the front side of the C-shaped mounting plate 201. The gear 204 is fixedly fitted onto the adjusting screw 202.

[0051] Two gears 204 pass through two side openings and extend into the slot 14, respectively, and mesh with two racks 4.

[0052] It also includes: a lower positioning magnet 3 and an upper positioning magnet 13. There are two lower positioning magnets 3, both of which are fixedly installed on the upper end of the first protective plate 1. The two lower positioning magnets 3 are symmetrically arranged on the left and right sides of the second protective plate 11. There are two upper positioning magnets 13, both of which are fixedly installed on the lower end of the upper mounting block 9. The two upper positioning magnets 13 are symmetrically arranged on the left and right sides of the second protective plate 11. The two lower positioning magnets 3 are located directly below the two upper positioning magnets 13. The upper positioning magnets 13 and the lower positioning magnets 3 are magnetically attracted to each other.

[0053] When not in use, the second protective plate 11 can be inserted into the first protective plate 1 through the slot 14 for storage, and the lower positioning magnet 3 can attract the upper positioning magnet 13 to fix the lower end of the upper mounting block 9 to the upper end of the first protective plate 1. The above design can reduce the storage volume of this utility model.

[0054] The positioning component 2 also includes a locking nut 203, which is threaded onto the adjusting screw 202. The locking nut 203 is located on the front side of the C-shaped mounting plate 201, and the adjusting screw 202 is rotatably connected to the C-shaped mounting plate 201 through a bearing.

[0055] In use, the upper mounting block 9 can be lifted up, thereby pulling the second protective plate 11 out from the first protective plate 1. At this time, the rack 4 drives the gear 204 to rotate, which in turn drives the adjusting screw 202 to rotate. When the second protective plate 11 moves to the appropriate position, tighten the locking nut 203 to lock the adjusting screw 202, thereby locking the second protective plate 11.

[0056] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
