[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] Embodiment 1:
[0021] As Figures 1-4 shown, the present utility model provides a wireless impact device for a Leeb hardness tester, which includes an impact device main body 1. A loading sleeve 2 is arranged on the outer surface of the impact device main body 1. A release button 3 is arranged on the top of the impact device main body 1. A support ring 4 is fixedly connected to the bottom of the impact device main body 1. A protection device 7 is fixedly connected to the outer surface of the impact device main body 1. A wireless transmitter 5 is fixedly connected to the inside of the impact device main body 1. A charging interface 6 is opened on the outer surface of the impact device main body 1. The protection device 7 includes a fixed sleeve 71, a first movable ring 73 and a second movable ring 75. A first spring 72 is fixedly connected to the upper surface of the fixed sleeve 71. A second spring 74 is fixedly connected to the lower surface of the fixed sleeve 71. Anti-slip convex strips 77 are fixedly connected to the outer surface of the fixed sleeve 71.
[0022] Specifically, one end of the first spring 72 away from the fixed sleeve 71 is fixedly connected to the lower surface of the first movable ring 73.
[0023] Specifically, one end of the second spring 74 away from the fixed sleeve 71 is fixedly connected to the upper surface of the second movable ring 75.
[0024] Specifically, a connecting plate 76 is fixedly connected to the inner surface of the fixed sleeve 71, and the outer surface of the connecting plate 76 is fixedly connected to the outer surface of the impact device main body 1.
[0025] Specifically, the first spring 72 and the second spring 74 are sleeved on the outer surface of the impact device main body 1, and the inner surfaces of the first movable ring 73 and the second movable ring 75 are sleeved and adapted to the outer surface of the impact device main body 1.
[0026] Specifically, the upper surface of the first movable ring 73 is flush with the top of the impact device main body 1, and the lower surface of the second movable ring 75 is flush with the bottom of the impact device main body 1.
[0027] The working principle and beneficial effects of the above embodiments.
[0028] In use, a wireless receiver is provided on the main body of the Leeb hardness tester. When the impact device main body 1 measures hardness, the wireless transmitter 5 converts the measured information into a wireless signal and transmits it. After receiving the signal, the wireless receiver on the main body decodes and processes it, and then transmits the information to the main body. The operation is made more convenient through wireless connection. The impact device main body 1 is not restricted by wires. The inside of the impact device main body 1 is equipped with a lithium-ion rechargeable battery, which is charged through the charging interface 6. When the impact device main body 1 accidentally drops, the impact force acts on the first spring 72 and the second spring 74. The first spring 72 and the second spring 74 can prevent the impact force from directly acting on the impact device main body 1, and the first spring 72 and the second spring 74 can stretch, without affecting the normal use of the impact device main body 1. The fixed sleeve 71 is the handheld part, and the anti-slip ridges 77 provided can increase the friction with the hand and prevent the device from slipping off the hand.
