Description

Technical Field

[0001] The utility model relates to the technical field of labor protection shoe soles, in particular to a labor protection shoe sole anti-puncture detection device. Background Art

[0002] As a labor protection product, labor protection shoes are widely used in production. They can protect the soles of the feet and prevent them from being punctured in various complex working environments. Therefore, the anti-puncture performance of labor protection shoes is very important. If the anti-puncture performance of labor protection shoes is too poor, employees are prone to safety accidents during work.

[0003] Application No. 202021066448.0 discloses an anti-puncture detection mechanism for the sole of a labor protection shoe. The clamping device of the mechanism adopts a left electromagnet and an iron block to present an electromagnetic attraction state when the wire is energized. Since the adsorption force is less than the hardness limit of the sole, the shoe is firmly clamped on the top of the probe by the clamping device. By adjusting the telescopic length of the telescopic rod, it can adapt to soles of different models and styles, thereby increasing the adaptability of the device; the testing device of the mechanism is a cone slidably inserted into the inside of the slide. Under the action of the bottom cylinder and the spring force, the cone and the sole are squeezed against each other. Since a vacuum channel is provided at the bottom of the cone, the bottom of the cone is subjected to additional upward squeezing force. The force of the squeezing part is transmitted to the data disk of the pressure display gauge through the pressure detector for the inspector to check. It is very easy to use and operate. When not in use, just release the cylinder.

[0004] The outer shell of the detection device equipped with the sole detection mechanism is flat and has a plurality of ejector pins thereon for detecting the puncture of the sole. However, the forefoot part of the sole of the safety shoe is in an arc-shaped raised shape, so that the flat detection device outer shell of the device cannot completely fit the sole of the safety shoe, thereby making the pressure uneven and causing errors in the detection data. Therefore, a safety shoe sole anti-puncture detection device is needed. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a labor protection shoe sole anti-puncture detection device.

[0006] The utility model is implemented by the following technical scheme: a labor protection shoe sole anti-puncture detection device, comprising a main body device, a fixing device is arranged at the bottom of the main body device, and a detection device is arranged at the top of the fixing device;

[0007] The main device includes a placement plate, a slide groove is provided on the top of the placement plate, a limiting groove is provided on the inner wall of the slide groove, a front sole top plate is slidably connected to the inner wall of the slide groove, a rear heel top plate is fixedly connected to the inner wall of the slide groove, a limiting block is slidably connected to the inner wall of the limiting groove, a contraction hole is provided on the top of the front sole top plate, a spring is fixedly connected to the inner wall of the contraction hole, and a ejector pin is fixedly connected to the top of the spring.

[0008] Through the above technical scheme, a slide groove is opened at the center position of the placement plate, and two identical and corresponding limit grooves are opened on the inner wall of the slide groove to place the limit block, so that the limit block can move left and right with the front sole top plate, while the rear heel top plate is guaranteed to be fixed and will not move. Therefore, it is only necessary to adjust the front sole top plate left and right to make the corresponding detection position according to the size of the sole.

[0009] As a further improvement of the above scheme, two limit grooves are provided, and the two limit grooves are symmetrically distributed with the front sole top plate as the center, two limit blocks are provided, and the two limit blocks are symmetrically distributed with the front sole top plate as the center, a number of shrinkage holes are provided, and the shrinkage holes are equidistantly distributed, a number of springs are provided, and the springs are equidistantly distributed, and a number of ejector pins are provided, and the ejector pins are equidistantly distributed.

[0010] Through the above technical scheme, a plurality of shrinkage holes are provided on the top of the front sole top plate and the rear heel top plate for placing springs and thimbles for detecting anti-puncture. When the sole of an external labor protection shoe is placed on the thimble and pressure is applied to the sole, the thimble will shrink downward according to the pressure of the spring. When the spring shrinks due to the pressure of the thimble, the spring will drive the front sole top plate and the rear sole top plate to be pressed downward, thereby releasing the downward pressure to the pressure detector, thereby realizing anti-puncture detection.

[0011] As a further improvement of the above solution, the surface of the front sole top plate is arranged in an arc shape.

[0012] Through the above technical solution, the arc-shaped setting is more likely to fit the bottom surface of the sole.

[0013] As a further improvement of the above solution, the fixing device includes a workbench, the workbench is fixedly connected to the bottom of the placement plate, and a threaded hole is opened on the top of the workbench.

[0014] Through the above technical solution, four threaded holes are provided so that the workbench can be fixed with external screw holes through bolts.

[0015] As a further improvement of the above solution, four threaded holes are provided, and the four threaded holes are distributed at four corners with the workbench as the center.

[0016] As a further improvement of the above solution, the detection device includes a pressure detector, which is fixedly connected to the top of the workbench, and a pressure display instrument is fixedly connected to the top of the workbench.

[0017] Through the above technical solution, when the pressure detector is subjected to pressure, the pressure it bears will be displayed on the pressure display instrument, so that the pressure data can be seen more intuitively.

[0018] As a further improvement of the above solution, the shape and size of the pressure detector corresponds to the shape and size of the slide slot.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] The utility model provides a slide groove at the center of the placement plate, and provides two identical and opposite limiting grooves on the inner side wall of the slide groove for placing limiting blocks, so that the limiting blocks can move left and right with the front sole top plate, while the rear heel top plate is guaranteed to be fixed and will not move. Therefore, the corresponding detection position can be made according to the size of the sole by only adjusting the front sole top plate left and right.

[0021] The utility model provides a plurality of shrinkage holes on the tops of the front sole top plate and the rear heel top plate for placing springs and ejector pins for detecting anti-puncture. When the sole of a labor protection shoe is placed on the ejector pin and pressure is applied to the sole, the ejector pin will shrink downward according to the pressure of the spring. When the spring shrinks under the pressure of the ejector pin, the spring will drive the front sole top plate and the rear sole top plate to be pressed downward, so that the downward pressure is released to the pressure detector, thereby realizing anti-puncture detection.
