Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fasteners, in particular to a special screw for a mine electromagnetic valve plug socket. Background Art
[0002] Screws are tools that use the physics and mathematics of an object's circular rotation and friction to gradually tighten objects and parts. They are a common fastener used extensively in machinery, electrical appliances, and buildings. They are generally made of metal or plastic, cylindrical in shape, and have a surface pattern of concave and convex grooves called threads.
[0003] A large number of screws are used to fasten various equipment in mines. When installing the mine solenoid valve plug socket, the lower surface of the screw head has a certain curvature after the common screws and sealing gaskets are matched. There is a gap between the contact surface of the sealing gasket and the screw, which cannot be completely sealed, which may cause water seepage in the threaded hole. At the same time, due to the complex environment in the mine, the screws are prone to rust, and the inside of the slot of the screw head will accumulate rust and dust, which makes it difficult to remove the screw after long-term use. For this reason, we propose a special screw for the mine solenoid valve plug socket. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a special screw for a mining solenoid valve plug socket. The screw is convenient for removing and cleaning rust and dust inside the slot by combining a cross slot and a slot, and has better sealing performance, which can effectively solve the problems in the background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a special screw for a mining solenoid valve plug socket, comprising a stud;
[0006] Stud: A nut is provided at the upper end of the stud, a cross slot is provided in the middle of the upper end of the nut, through slots are provided at both ends of the cross slot, and the two through slots and the transverse slot of the cross slot form a slotted slot. The combination of the cross slot and the slotted slot facilitates the removal and removal of rust and dust inside the slot, while also providing better sealing.
[0007] Furthermore, the lower surface of the nut is flat to prevent water leakage.
[0008] Furthermore, the two through grooves are both provided with V-shaped openings at their opposite outer ends, and the V-shaped openings increase the cross-section of the through grooves.
[0009] Furthermore, slopes are provided on both the front and rear sides of the cross slot to prevent dust from accumulating at the bottom of the vertical slot of the cross slot.
[0010] Compared with the prior art, the beneficial effects of the present invention are: the special screw for the plug seat of the mining solenoid valve has the following advantages:
[0011] 1. When disassembly is required, use a sharp object to pick out the dust accumulated inside the cross slot and the through slot. The V-shaped opening increases the cross-section of the through slot, making it easier for sharp objects to enter the interior of the cross slot and to remove the special screws for the mine solenoid valve plug socket.
[0012] 2. The lower surface of the nut is flat, and the upper surface of the sealing gasket and the lower surface of the nut are in full contact to avoid water leakage. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 This is a schematic diagram of the structure of the utility model;
[0014] Figure 2 This is a schematic diagram of the structure of the utility model when viewed from above.
[0015] In the figure: 1 stud, 2 nut, 3 cross slot, 4 through slot, 5 slope, 6 V-shaped opening. DETAILED DESCRIPTION
[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0017] See also Figure 1-2 , This embodiment provides a technical solution: a special screw for a mining solenoid valve plug socket, including a stud 1;
[0018] Stud 1: A nut 2 is provided at its upper end, and a cross slot 3 is provided in the middle of the upper end of the nut 2. A through slot 4 is provided at both ends of the cross slot 3. The two through slots 4 and the transverse slot of the cross slot 3 form a straight slot. The lower surface of the nut 2 is flat, and the two through slots 4 are provided with a V-shaped opening 6 at the opposite outer ends. The front and rear sides of the cross slot 3 are provided with slopes 5. When disassembly is required, a sharp object can be used to pick out the dust accumulated inside the cross slot 3 and the through slot 4. At the same time, the front and rear sides of the cross slot 3 are provided with slopes 5 to prevent dust from accumulating at the bottom of the vertical slot of the cross slot 3. The V-shaped opening 6 increases the cross-section of the through slot 4, making it easier for sharp objects to enter the interior of the cross slot 3.
[0019] The working principle of the special screw for mining solenoid valve plug socket provided by the utility model is as follows: when installing the special screw for mining solenoid valve plug socket, first set a sealing gasket on the outside of the stud 1, and the upper surface of the sealing gasket is in full contact with the lower surface of the nut 2 to prevent water leakage. Use a flat-blade screwdriver to align the two through grooves 4 and the transverse groove of the cross groove 3 to form a flat-blade slot, or use a cross screwdriver to align the cross groove 3 for installation. When disassembly is required, a sharp object can be used to pick out the dust accumulated inside the cross groove 3 and the through groove 4. At the same time, slopes 5 are provided on the front and back sides of the cross groove 3 to prevent dust from accumulating at the bottom of the vertical groove of the cross groove 3. The V-shaped opening 6 increases the cross-section of the through groove 4, which is convenient for sharp objects to enter the interior of the cross groove 3.
[0020] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
