Technical Field

[0001] This utility model relates to the field of observation hole nuts, specifically a device for a special screwdriver for observation hole nuts. Background Technology

[0002] The existing gas-fired vertical kilns each have 10 burners in two rows, with a total of 120 burners in 6 kilns. However, due to the high pulverization rate of local limestone, dust floats heavily inside the kiln during calcination, resulting in severe pulverization of the finished product.

[0003] In some equipment on the market, when using vertical kilns for calcination, there is a serious problem of dust floating inside the kiln, and the gas contains moisture and impurities, which causes the burner sight glass to become dirty, making it impossible to observe the movement of the material column inside the kiln and the calcination flame. It is necessary to stop the ventilation and wipe it clean.

[0004] However, in actual use, the above-mentioned equipment takes a long time to clean and wipe the vertical kiln during the shutdown period, which will affect the output, quality, and kiln temperature. It will also cause kiln conditions, thus affecting the smooth operation of production. In view of this, we propose a device for a special screwdriver for observation hole nuts. Utility Model Content

[0014] Compared with the prior art, this utility model provides a device for a special screwdriver for observation hole nuts, which has the following beneficial effects:

[0015] 1. The device for the special screwdriver for the observation hole nut is designed to allow the nut to be turned off evenly. The operator uses an electric wrench to align the screwdriver with the wrench and inserts it into the wrench. When the electric wrench is turned, the screwdriver causes the reinforcing plate to rotate as well, making it easy to turn off the nut. This allows the operator to quickly clean the burner sight glass in a short time, thus effectively preventing kiln problems caused by prolonged shutdown.

[0016] 2. The device for this special screwdriver for observation hole nuts is designed to make the connection between the screwdriver and the electric wrench more secure. When the electric wrench is aligned with the screwdriver and inserted, the connection of the electric wrench contacts the inside of the groove and squeezes the ball bearings. This causes the ball bearings to compress the spring. After the electric wrench and the screwdriver are fully engaged, the spring force pushes the ball bearings to contact the connection of the electric wrench, thereby increasing the friction between the electric wrench and the screwdriver and allowing the nut to be turned off more quickly.

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: a device for a special screwdriver for an observation hole nut, including a nut 1, a disassembly assembly 2 provided at the bottom of the nut 1, the disassembly assembly 2 including a rib 201, a screwdriver 202 and a slot 203.

[0023] In this embodiment of the utility model, the reinforcing plate 201 is fixedly connected to the bottom of the nut 1, and the center of the reinforcing plate 201 corresponds to the center of the nut 1. The bottom of the reinforcing plate 201 has a through hole, and the size of the through hole is adapted to the size of the screw hole of the nut 1. This allows the nut 1 to be subjected to force more evenly when the reinforcing plate 201 rotates. The bottom of the reinforcing plate 201 is fixedly connected to a screwdriver 202, and the size of the screwdriver 202 is adapted to the size of the reinforcing plate 201. The center of the screwdriver 202 corresponds to the center of the reinforcing plate 201. This allows the reinforcing plate 201 to rotate evenly when the screwdriver 202 rotates. The bottom of the screwdriver 202 has a slot 203. There are two slots 203, and the two slots 203 are symmetrically arranged around the center of the reinforcing plate 201. This allows the electric wrench to better engage with the screwdriver 202.

[0024] Meanwhile, an auxiliary component 3 is provided on the inner wall of the slot 203. The auxiliary component 3 includes a placement groove 301, which is formed on the inner wall of the slot 203. The placement grooves 301 are evenly distributed in a linear array on both sides of the inner wall of the slot 203. The center of the placement groove 301 corresponds to the center of the spring 302. The spring 302 is fixedly connected to the inner wall of the placement groove 301. A ball bearing 303 is provided at the end of the spring 302. The size of the ball bearing 303 is adapted to the size of the placement groove 301. The center of the ball bearing 303 corresponds to the center of the spring. The center of 302 corresponds to the center of the screwdriver 202. When the electric wrench is aligned with the screwdriver 202 and inserted, the connection of the electric wrench contacts the inside of the slot 203 and squeezes the ball 303. This causes the ball 303 to compress the spring 302. After the electric wrench is fully engaged with the screwdriver 202, the elastic force of the spring 302 pushes the ball 303 to contact the connection of the electric wrench, thereby increasing the friction between the electric wrench and the screwdriver 202, allowing the nut 1 to be turned off more quickly.

[0025] In this utility model, when in use, the operator uses an electric wrench to align with the screwdriver 202, allowing the screwdriver 202 to engage inside the electric wrench. This allows the screwdriver 202 to rotate along with the rib plate 201 when the electric wrench is turned, thus allowing the nut 1 to be easily unscrewed. This enables the operator to quickly clean the burner sight glass in a short time, thereby effectively preventing kiln problems caused by prolonged shutdown time.

[0026] Furthermore, when the electric wrench is aligned with the screwdriver 202 and engaged, the connection of the electric wrench contacts the inside of the slot 203 and compresses the ball bearing 303. This causes the ball bearing 303 to compress the spring 302 and contract. After the electric wrench is fully engaged with the screwdriver 202, the elastic force of the spring 302 pushes the ball bearing 303 to contact the connection of the electric wrench, thereby increasing the friction between the electric wrench and the screwdriver 202, allowing the nut 1 to be turned off more quickly.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
