Description

Technical Field

[0001] This utility model relates to the field of switch screw technology, specifically a novel switch screw. Background Technology

[0002] Screws are indispensable fasteners in the switch installation process. They are mainly used to fix the switch housing to the mounting surface and ensure the stability of the switch installation.

[0003] Existing switch screws have certain drawbacks: on the one hand, the outer surface of the screw head is mostly smooth or has a simple polygonal structure, which can easily cause the tool to slip during tightening or disassembly, affecting operational efficiency and even potentially damaging the head; on the other hand, most switch screws are only compatible with a single type of tool, such as having only slotted or Phillips head slots. When the corresponding tool is missing, installation or disassembly cannot be performed smoothly, resulting in poor compatibility. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the prior art, this utility model provides a novel switch screw, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel switching screw, comprising a nut, an anti-slip gear, a slotted tool positioning groove, a Phillips head tool positioning groove, a hexagonal head tool positioning groove, and a screw rod. The anti-slip gear is integrally formed on the outer wall of the nut and is evenly distributed along the circumference of the nut. The slotted tool positioning groove, the Phillips head tool positioning groove, and the hexagonal head tool positioning groove are all formed on the upper surface of the nut. The Phillips head tool positioning groove is located in the middle of the slotted tool positioning groove and intersects each other perpendicularly. The hexagonal head tool positioning groove surrounds the outer side of the Phillips head tool positioning groove. The screw rod is fixedly connected to the lower surface of the nut near the center position, and the screw rod is coaxial with the nut.

[0008] Preferably, the anti-slip gear has a tooth height of 0.8-1.5 mm and a tooth thickness of 0.5-1 mm, and the tooth groove width between two adjacent teeth is adapted to the tooth thickness.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a novel switch screw, which has the following beneficial effects:

[0015] 1. This new type of switch screw increases the friction between the nut and the operating tool by setting evenly distributed anti-slip gears on the outside of the nut, effectively avoiding slippage during tightening or disassembly, protecting the nut from damage, and improving the stability and efficiency of operation.

[0016] 2. This new type of switch screw integrates three tool positioning slots: flathead, Phillips, and hexagonal. It can be used with commonly used flathead screwdrivers, Phillips screwdrivers, and Allen wrenches, eliminating the need to specifically search for the corresponding tools. This greatly facilitates installation and disassembly operations and makes it applicable to a wider range of scenarios. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-2This utility model provides a technical solution: a novel switching screw, comprising a nut 1, an anti-slip gear 2, a slotted tool positioning groove 3, a cross-shaped tool positioning groove 4, a regular hexagonal tool positioning groove 5, and a screw 6. The anti-slip gear 2 is integrally formed on the outer wall of the nut 1 and is evenly distributed along the circumference of the nut 1. The slotted tool positioning groove 3, the cross-shaped tool positioning groove 4, and the regular hexagonal tool positioning groove 5 are all opened on the upper surface of the nut 1. The cross-shaped tool positioning groove 4 is located in the middle of the slotted tool positioning groove 3 and intersects each other perpendicularly. The regular hexagonal tool positioning groove 5 surrounds the outer side of the cross-shaped tool positioning groove 4. The screw 6 is fixedly connected to the lower surface of the nut 1 near the center position, and the screw 6 is coaxially arranged with the nut 1.

[0022] In order to balance the anti-slip effect of the anti-slip gear with the overall structural strength of the nut, and to avoid the problems of anti-slip failure due to excessively low tooth height or easy breakage due to excessively high tooth height, and tool compatibility due to improper tooth thickness, the anti-slip gear 2 is designed with a tooth height of 0.8-1.5mm and a tooth thickness of 0.5-1mm. The tooth groove width between two adjacent teeth is matched with the tooth thickness to ensure sufficient friction during operation and that the gear is not easily deformed or damaged.

[0023] In order to make the slotted tool positioning groove compatible with mainstream slotted screwdrivers and to avoid the tool being unable to be inserted or slipping out due to improper groove width or depth, while ensuring uniform torque transmission, the slotted tool positioning groove 3 is set with a groove width of 2-4mm and a groove depth of 3-5mm. Its length is adapted to the end face diameter of the nut 1, which improves the stability and efficiency of operation.

[0024] In order to achieve tool versatility between the flat-bottom tool positioning groove 3 and the cross tool positioning groove 4, reduce the number of tools to carry, and avoid stress concentration at the cross intersection causing the groove to crack, the cross tool positioning groove 4 is designed with the same groove width and groove depth as the flat-bottom tool positioning groove 3, and the bottom of the groove at the cross intersection is rounded to extend the structural life and optimize the operating feel.

[0025] In order to adapt the regular hexagonal tool positioning groove 5 to a standard hexagonal wrench to enhance torque transmission capability, and at the same time avoid the groove being too deep and weakening the strength of the nut 1, or too shallow and causing the tool to slip off, the present invention sets the distance between opposite sides of the regular hexagonal tool positioning groove 5 to be 5-8mm, the groove depth to be 2-3mm, and its center to coincide with the center of the nut 1, thus balancing torque transmission and structural compactness.

[0026] In order to adapt the screw 6 to the installation requirements of switches of different thicknesses, and to avoid low operating efficiency due to excessively small pitch or easy loosening due to excessively large pitch, and connection stability due to improper diameter, the outer wall of the screw 6 is provided with an external thread. The pitch of the external thread is 1-2mm, the length of the screw 6 is 8-20mm, and the diameter is 4-8mm, so as to ensure adaptability and connection firmness.

[0027] When using the screwdriver, select the appropriate positioning slot based on the available tools: insert it into the flathead tool positioning slot 3 when using a flathead screwdriver; insert it into the Phillips head tool positioning slot 4 when using a Phillips head screwdriver; and insert it into the regular hexagonal tool positioning slot 5 when using an Allen wrench. During operation, the anti-slip gear 2 contacts the tool or hand, increasing friction and preventing slippage. Rotating the tool will drive the screw rod 6 to rotate, thus tightening or loosening the screw.

[0028] The dimensions and shapes of all components in this structure are not specifically limited here and need to be produced according to the actual situation.
