Description

Technical Field

[0001] The utility model relates to the field of testing and measuring devices, in particular to a device for testing plastic deformation of a fence. Background Art

[0002] At present, in order to meet specific usage requirements, some fences are made of stainless steel, and such stainless steel fences need to have a certain rigidity. In order to test its plastic deformation, the current method is to place the fence flat on the table and stand a ruler next to it. The operator bends the fence to the height specified by the inspection standard by hand, then releases his hand and waits for the fence to return to its original shape before measuring the actual deformation. However, since the operator needs to pay attention to the scale of the ruler at the same time, the force applied is inconsistent, which affects the accuracy of the measurement results. In addition, the operator needs to stare at the scale at all times during the process of bending the fence, which increases the inconvenience of operation. Summary of the invention

[0003] In view of the deficiencies in the prior art, the utility model provides a convenient and quick detection device for plastic deformation of a fence.

[0004] The technical solution of the utility model is: a device for inspecting the plastic deformation of a fence, comprising a base plate, a support seat, a column, a pressure rod, a block and a pin shaft, the support seat and the column are respectively fixed on the base plate, a limiting groove is provided on the upper side of the support seat, two blocks are arranged on the back of the column, and are respectively fixed on both sides of the limiting groove, a positioning groove is provided on the upper side of the column, and pin shaft support holes are horizontally provided on both sides of the positioning groove, an axial hole is provided at one end of the pressure rod, which is arranged on the inner side of the column positioning groove, and is hinged with the upper end of the column through the pin shaft, a pressure block is provided at the other end of the pressure rod, and the pressure rod can use the pin shaft as the axis to drive the pressure block to move up and down in the limiting groove of the support seat.

[0005] The technical effects of the utility model are:

[0006] Firstly, the utility model simplifies the detection process of the plastic deformation of the fence by designing a reasonable device structure. The operator no longer needs to pay attention to the scale of the ruler and the applied force at the same time, and only needs to adjust the position of the pressure rod to complete the operation. This simplified operation feature greatly improves the convenience of operation.

[0007] Secondly, because the operator no longer needs to stare at the scale, the force applied is more consistent, which improves the accuracy of the measurement results. This helps ensure that the measurement results of the plastic deformation of the fence are more reliable.

[0008] Finally, the design of the new device reduces the operator's human error and improves the efficiency of the operation. Through the fixation and control of the mechanical device, the possibility of error is reduced, further ensuring the accuracy and reliability of the measurement results.

DETAILED DESCRIPTION

[0016] The utility model is further described below in conjunction with the accompanying drawings.

[0017] like Figure 1-6 As shown, a device for inspecting plastic deformation of a fence includes a base plate 1, a support seat 2, a column 3, a pressure rod 4, a stopper 5 and a pin 6.

[0018] The bottom plate 1 is a rectangular parallelepiped plate, and a plurality of countersunk holes are opened from the bottom to the top; among them, the front four are support seat mounting countersunk holes 1-1 for mounting the support seat 2, and the rear two are column mounting countersunk holes 1-2 for mounting the fixed column 3;

[0019] The support seat 2 is rectangular in shape, with a U-shaped limit groove 2-1 on the upper side, and the limit groove 2-1 can be processed into different depths according to the height specified by the inspection standard of the fence 7 to be inspected; a support seat installation threaded hole 2-2 is opened at the bottom of the support seat 2, and the position of the support seat installation threaded hole 2-2 corresponds to the support seat installation countersunk hole 1-1, which is used to install and fix the support seat on the base plate 1 by screws, and a stopper installation threaded hole 2-3 is opened at each end of the back side of the support seat 2 near the upper side of the limit groove 2-1; for installing the stopper 5;

[0020] The column 3 is rectangular in shape, with a U-shaped positioning groove 3-1 on the upper side and a column mounting threaded hole 3-2 on the bottom; symmetrical pin support holes 3-3 are respectively provided at both ends of the positioning groove 3-1; the hole diameter thereof is larger than the pin 6 and can be matched with the pin 6 in clearance;

[0021] The side of the pressure rod 4 is T-shaped, and an axial hole 4-2 is opened at one end of the crossbeam. The hole diameter is larger than the pin 6 and can be matched with the pin 6. The column is a pressure block 4-1;

[0022] The stopper 5 is two symmetrical L-shaped sheets, each of which is provided with a stopper mounting screw hole 5-1 for connecting and fixing with the support seat 2, and a limit block 5-2 is processed at the front end of the top of the vertical column; it is used to locate the connecting rod 7-1 of the fence 7 to be inspected and limit the movement of the fence 7 when in use;

[0023] The length of the pin 6 is greater than the width of the column 3 .

[0024] When assembling the inspection device, first fix the block 5 on the support base 2 with screws, use a cup head screw to pass through the support base mounting countersunk hole 1-1 and connect it with the support base mounting threaded hole 2-2, and tighten to fix the support base 2; similarly, use a cup head screw to pass through the column mounting countersunk hole 1-2 and connect it with the column mounting threaded hole 3-2, and tighten to fix the column 3; place one end of the axial hole 4-2 of the pressure rod 4 into the positioning groove 3-1 of the column 3, and use the pin 6 to pass through the pin support hole 3-3 of the column 3 and the axial hole 4-2 of the pressure rod 4 respectively. Since the pin 6 is respectively matched with the pin support hole 3-3 and the axial hole 4-2, the pressure rod can use the pin as the axis and can rotate freely up and down, thereby driving the pressure block 4-1 to move up and down in the limit groove 2-1.
