The main concern is how these swords will protect people from the self-infestation, which is the impact of a knife stab for that purpose. Therefore, in testing the performance of the sword suit, the degree of resistance to insects should be tested.

Conventional sword suit tester is using a method to test the performance of the sword suit by raising the sword using an electromagnet applied by the voltage applied, and then stop the voltage supply to lower the sword. However, this method has a problem in that when the sword is set in the lower state of the sword when the worker sets the sword suit, there is a risk of falling of the sword.

In particular, when an unexpected power failure occurs in the operator's laboratory, the supply of the voltage is interrupted and the sword is lowered, so that the difficulty of securing the safety of the worker becomes more serious.

Figure 4 is a cross-sectional view showing the height adjustment unit 150 used in the bat wear tester 100 according to the present invention. 5 is a cross-sectional view showing the lower portion 170 used in the sword tester 100 according to the present invention. Figure 6 is a photograph of a sword suit tester 100 according to the present invention.

1 to 6, the sword suit tester 100 according to the present invention includes a support 110, a controller 120, a motor 130, a rail 140, a height adjuster 150, and a wire 160. ), The lower portion 170 may be included.

The support 110 supports the overall driving of the anti-wear tester 100 according to the present invention. The support 110 includes a susceptor 111 for mounting a protective suit and a vertical support 112 formed in a direction perpendicular to the susceptor 111 to support the rail 150.

The controller 120 controls the voltage applied to the motor 130 and the height adjuster 150 of the bat wear tester 100 according to the present invention. The controller 120 may adjust the height of the height adjusting unit 150 by adjusting the rotation speed and the amount of rotation of the motor 130 through the voltage applied to the motor 130. In addition, the controller 120 adjusts the voltage applied to the height adjusting unit 150 to couple the height adjusting unit 150 and the lowering unit 170, and drives the motor 130 to adjust the height. After raising the unit 150 and the lowering unit 170, the lowering unit 170 may be detached from the height adjusting unit 150 to lower the lowering unit 170.

The motor 130 is electrically connected to the controller 120. The motor 130 receives the electrical signal from the controller 120 to rotate the rotating shaft 131. The motor 130 has a gear 132 coupled to the rotation shaft 131.

The chain 133 is connected to the gear 132 connected to the rotation shaft 131 of the motor 130. The chain 133 is rotated by the gear 132 to change the position of the wire 170 coupled to the chain 133. Therefore, the chain 133 connected to the motor 130 changes the positions of the height adjusting part 150 and the lowering part 170 by applying tension to the wire 170.

In addition, an encoder (not shown) may be electrically connected to the controller 120 and the motor 130. An encoder is electrically connected to the controller 120 and the motor 130. The encoder measures the amount of rotation of the rotating shaft 131 of the motor 130. The encoder 120 may apply a pulse during the driving period of the motor 130 to measure the driving time of the motor. Therefore, the controller 120 measures the height of the height adjusting unit 150 and the lowering unit 170 coupled thereto according to the rotation amount of the motor 130 measured by the encoder. Therefore, the controller 140 stops driving of the motor 130 when the height adjusting unit 150 and the lowering unit 170 reach a desired position, and thus the height adjusting unit 150 and the lowering unit 170. Fix the position of.

The rail 140 is formed to be parallel to the vertical support 112 of the support 110. The rail 140 provides a vertical movement path of the height adjusting part 150 and the lowering part 170. Since the lower portion 170 descends along the rails 140 when the upper portion of the shielding suit falls, the lower portion 170 does not contact the other structures. In addition, the rail 140 may be formed using a high-strength polishing rod polished surface to reduce friction with the lower portion 170. Therefore, the falling portion 170 falling along the rail 140 may fall at a speed close to the acceleration of gravity.

In addition, the rail 140 has an acrylic tube 141 surrounding its outer circumference. The acrylic tube 141 is restricted so that the lower portion 170 maintains a horizontal position even when the height adjusting portion 150 and the lower portion 170 is separated from the rail 140. Therefore, it is possible to ensure the safety of the worker from the lower portion (170).

The height adjusting part 150 is connected to the chain 133 by the wire 160. In addition, the height adjusting unit 150 is combined with the lowering unit 170 to raise the lowering unit 170 in the vertical direction, and then detached to allow the lowering unit 170 to fall. The height adjusting unit 150 has a groove therein, and the groove is coupled to the rail 140 to ensure the movement of the height adjusting unit 150 in the vertical direction.

The height adjusting part 150 may include a shaft 151, a coupling part 152, a support part 153, a spring 154, and a coil 155.

The shaft 151 is formed in pairs side by side in the radial direction of the height adjustment unit 150. The shaft 151 is formed while penetrating the upper side of the coupling portion 152. The shaft 151 fixes the upper side of the coupling portion 152 to allow the lower side of the coupling portion 152 to move relative to the shaft 151.

The coupling portion 152 is fixed to the upper side by the shaft 151, the lower side can be rotated based on the shaft 151.

In addition, the coupling part 152 is provided with a ring 172a protruding to the side at the lower portion to allow the lower portion 170 to be coupled to the ring 172a. The ring 172a includes a first inclined surface 172b that is inclined to have a first slope inward and a second inclined surface 172c that is inclined to have a second inclination outward. Here, the first inclined surface 172b comes into contact with each other when the coupling part 152 is not supported by the support part 153. As a result, the ring 172a abuts, and the coupling part 152 is detached from the lower part 170. The second inclined surface 172c is a portion that comes in contact with the lower portion 170. In addition, since the second inclined surface 172c has a second inclined surface, when the ring 172a abuts, the lower portion 170 may be easily detached along the second inclined surface 172b.

The support part 153 may move in a vertical direction between the shafts 151 of the coupling part 152. When the support part 153 is lower than the shaft 151, the lower side of the coupling part 152 is supported by the support part 153. Thus, the lower portion 170 is coupled by the ring 172a of the coupling portion 152. On the other hand, if the support portion 153 is higher than the shaft 151, the lower side of the coupling portion 152 is not supported, the ring 172a is gathered in the center and the lower portion 170 is detached. Therefore, the lowering unit 170 is lowered so that the test can be performed by applying a self-protection (刺 衝) to the sword suit.

The spring 154 is provided in the vertical direction inside the height adjusting part 150. The spring 154 pushes the support 153 by an elastic force. Accordingly, the support 153 is basically inserted between the shafts 151 of the coupling part 152 by the spring 154 to maintain the coupling part 152. In addition, after the spring 154 is compressed, the support 153 is raised to the upper portion of the shaft 151 so that the coupling portion 152 is gathered in the center so that the coupling portion 152 is the lower portion 170. It is detached from).

The coil 155 is formed along the circumference of the support part 153 in the height adjusting part 150. The coil 155 may operate as an electromagnet by receiving a DC voltage from the wire 160. That is, when a current flows in the coil 155, a magnetic field induced inwardly of the coil is generated, and the support 153 receives a force to rise upward by the magnetic field. Therefore, when the coil 155 operates as an electromagnet, the elastic force of the spring 154 is canceled to raise the support part 153, so that the lower part 170 is detached from the coupling part 152.

The wire 160 is electrically connected between the controller 120 and the coil 155 of the height adjuster 150. The wire 160 receives a DC voltage from the controller 120 and applies it to the coil 155. Thus, the coil 155 can operate as an electromagnet.

In addition, the wire 160 applies a tension to the height adjustment unit 150, so that the height adjustment unit 150 can be raised or lowered. Thus, the height adjusting unit 171 and the lowering unit 170 may be raised. In addition, after the lowering unit 170 is lowered, the height adjustment unit 150 is also slowly lowered by the wire 160 to be combined with the lowering unit 170 can be repeated the test operation of the sword suit. . To this end, the wire 160 may be fixed to the chain 133. Therefore, the wire 160 is rotated together with the chain 150 even if the chain 133 is rotated to increase the position of the height adjustment unit 150, the coupling portion 152 of the height adjustment unit 150 ) To stay connected.

The lower portion 170 is detached from the height adjusting unit 150 is lowered to the upper portion of the sword suit. The lower portion 170 is to give the insects (충) to the sword suit, as a result of the test of the sword suit is in progress.

The lower portion 170 includes a sword portion 171, a male screw portion 172, and a female screw portion 173. The sword unit 171 is provided with a sword blade at the bottom. In addition, the sword portion 171 is the body of the upper blade is coupled to the male screw portion 172.

The male screw portion 172 has a structure surrounding the body of the sword portion 171. The male screw portion 172 is coupled to the body of the sword portion 171 through a coupling member such as a bolt or screw. In addition, the male screw portion 172 has a screw line on the outside thereof.

The female screw portion 173 has a screw thread therein. Therefore, the female screw portion 173 may be coupled to the male screw portion 172. In addition, the female screw portion 173 may be provided with an elastic member such as styrofoam therein to absorb the shock transmitted from the male screw portion 172.

The female screw portion 173 has a first hole 173a having a first diameter thereon and a second hole 173b formed below the first hole 173a and having a second diameter thereon. And the first diameter is smaller than the second diameter. Therefore, the first hole 173a and the second hole 173b form a step 173c. As a result, the hook 172a of the coupling part 152 of the height adjustment part 150 may be engaged to the step 173c.

In addition, a position sensor (not shown) may be further formed on the side of the susceptor 111 of the support 110 and electrically connected to the controller 120. The position sensor senses the time when the lower portion 170 passes in the horizontal direction. Since the time at which the lowering unit 170 starts lowering is recorded in the controller 120, the speed and acceleration of the lowering unit 170 are calculated by using the sensing time of the position sensor, so that the lower garment is worn on the sword suit. The force applied can be calculated.

Hereinafter will be described the operation of the sword suit tester 100 according to the present invention.

First, the height adjusting unit 150 and the lowering unit 170 is coupled through the coupling unit 152 and the step 173c. At this time, the coupling part 152 of the height adjusting part 150 is supported by the support part 153 by the elastic force of the spring 154 to maintain the coupling.

The controller 120 drives the motor 130. Therefore, the height adjusting part 150 and the lowering part 170 are raised in the vertical direction along the rail 140 by the chain 133 and the wire 160 connected to the motor 120. When the height adjusting unit 150 rises to a desired height, the controller 120 stops driving of the motor 130 to maintain the height of the height adjusting unit 150.

Thereafter, the sword suit is placed on the susceptor 111 of the support 110. At this time, the height adjustment unit 150 is coupled to the lower portion 170 by the elastic force of the spring 154, not by electrical energy, so that the safety of the operator even if there is an unexpected power failure Can be guaranteed.

Thereafter, the controller 120 applies a DC voltage to the coil 155 of the height adjusting unit 150 through the wire 160. Thus, a magnetic force is formed in the coil 155, the support portion 153 is raised, the coupling portion 152 is gathered to the center and the lower portion 170 is detached from the coupling portion 152. .

Thereafter, the lower portion 170 is lowered along the rail 140 to the upper portion of the sword suit. In addition, the controller 120 receives the time when the lower portion 170 reaches the sword suit from a position sensor, calculates the speed and acceleration of the lower portion 170, and as a result, is applied to the sword suit. Calculate the force.

As described above, the sword suit tester 100 according to the present invention may operate. Therefore, while the height adjusting unit 150 is coupled to the lowering unit 170, the voltage is not supplied to the height adjusting unit 150, and the coupling is maintained by the elastic force of the spring 154, so that the operator The safety of the operator can be guaranteed while setting the protective suit.

In addition, as described above, the anti-wear tester 100 according to the present invention can increase the accuracy of the test by allowing the lower portion 170 to descend to the correct position along the rail 140.

In addition, as described above, the anti-wear tester 100 according to the present invention allows the lower portion 170 to be coupled to the male screw portion 172 provided with a sword and the female screw portion 173 on the upper portion thereof by a screw thread. The elastic member inside the lower portion can be easily replaced.
