Description

Technical Field

[0001] This utility model belongs to the field of key technology, specifically relating to a curved key head with a scissor handle. Background Technology

[0002] A key typically consists of a key head and a key handle, with the key handle accounting for a large proportion of the overall weight. Generally, the key head needs to be made of metals such as copper. However, the price of such metals is relatively high, making the material cost of the key quite expensive. Therefore, some keys use a combination of two materials: the key head is made of metals such as copper, while the key handle is made of other metals that are cheaper. The key head and key handle are processed separately and then pressed together by press fitting.

[0003] The problem with existing technology is that it is not easy to find the position of the keyhole in the dark for alignment at both ends of the lock cylinder, and the end face of the conventional key head is a flat right angle, which is not convenient for blind insertion into the lock cylinder hole.

[0021] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-5 The present invention provides a technical solution: a scissor handle arc key head, including a gourd lock housing 1, both ends of the gourd lock housing 1 are provided with guide components 2, and one side of the gourd lock housing 1 is provided with a key component 3 that works in conjunction with the guide components 2;

[0023] The guide assembly 2 includes a lock cap 201, a guide hole 202, and a guide groove 203. The lock cap 201 is disposed at both ends of the gourd lock housing 1. The guide hole 202 is opened on the side wall of the lock cap 201. The guide groove 203 is opened on the side wall of the lock cap 201 and communicates with the guide hole 202.

[0024] The above solution is adopted by setting a lock cylinder cap 201, a blind hole 202, a blind groove 203 and a key assembly 3. The blind hole 202 and the blind groove 203 are designed to make it easy to find the keyhole in the dark environment. When used with the key assembly 3, it has a good blind opening function. By setting the key assembly 3, it is easy to blindly insert the lock cylinder. When carrying it, it is not easy to hurt people or puncture pockets.

[0025] refer to Figure 3 The key assembly 3 includes a scissor-shaped key handle 301, an arc-shaped key head 302, and a chamfered portion 303. The scissor-shaped key handle 301 is disposed on one side of the gourd lock housing 1, the arc-shaped key head 302 is fixedly connected to the side wall of the scissor-shaped key handle 301, and the chamfered portion 303 is disposed on the end face of the arc-shaped key head 302.

[0026] The above solution is adopted: by setting a scissor-shaped key handle 301, a rounded key head 302 and a chamfered part 303, the scissor-shaped key handle 301 is shaped like scissors, which feels substantial when in use and provides appropriate force when turning the lock cylinder. The conventional key head is a flat right angle, and the improvement to a rounded surface makes it easier to blindly insert into the lock cylinder hole. It is also less likely to injure people or puncture pockets when carried.

[0027] refer to Figure 4 Both ends of the gourd lock housing 1 are provided with chamfered corners 4, and the side wall of the lock cylinder cap 201 is provided with chamfered corners 5.

[0028] The above solution involves setting chamfers 4 on both ends of the lock shell and chamfer 5 on the cylinder surface. Conventional products have flat ends, which can cause varying degrees of edge flaring during electroplating, preventing the lock from passing through the lock body panel hole during installation. The conventional solution is to reduce the external dimensions of the lock shell or increase the size of the panel hole, resulting in a large gap in the fit, sometimes even allowing light to shine through from the outside. The modified chamfering eliminates these problems and allows the lock shell to smoothly pass through the lock body panel hole, achieving a perfect, precise fit. The conventional chamfer 5 on the cylinder surface is simply a solution to address burrs. This chamfer, combined with the 3.5mm height of the 201 cylinder cap, highlights the high-end quality of the lock cylinder and enhances the overall product image.

[0029] refer to Figure 5 The top and bottom of the scissor-type key handle 301 are fixedly connected to two injection-molded handles 6, which are made of PC material.

[0030] The above solution involves setting a PC material injection molded handle 6, which is 2.0 mm higher than the scissor-type key handle 301. This improves wear resistance, and in cold, low-temperature regions, PC material has a better temperature barrier effect than pure metal, making it widely used in low-temperature areas.

[0031] refer to Figure 4 Both ends of the top of the hoist lock housing 1 are provided with anti-drilling pins 7, which are made of alloy steel.

[0032] The above solution is adopted: by setting anti-drilling pins 7 made of alloy materials, the performance of anti-pry and anti-drilling is ensured.

[0033] refer to Figure 5 The top of the scissor-shaped key handle 301 has a through hole 8, which passes through the scissor-shaped key handle 301.

[0034] The above solution allows for easy connection of the key fob to the entire key via the through hole 8, greatly improving its practicality.

[0035] The working principle of this utility model:

[0036] In use, conventional products have flat ends. During electroplating, varying degrees of edge turning occur, preventing the lock from passing through the lock body panel hole during installation. The conventional solution is to reduce the external dimensions of the lock case or increase the panel hole size. The drawback is a large gap in the fit, sometimes so large that internal light spots are visible from the outside. After technical modification, the chamfered ends eliminate the problems caused by electroplating and allow the lock case to smoothly pass through the lock body panel hole, achieving a perfect, precise fit. The standard chamfer 5 on the cylinder surface is simply a solution to address burrs. This chamfer, combined with the 3.5mm height of the cylinder cap 201, highlights the high-end quality of the lock cylinder and enhances the overall product image. The guide hole 202 is designed to facilitate finding the keyhole in dark environments. Used with the rounded key head 302, it provides excellent blind opening functionality. The guide groove 203 is also designed to facilitate finding the keyhole in dark environments. The computer lock cylinder also features this function, but unlike others, the guide groove 203 combines the 3.5mm height of the cylinder cap 201 with the guide hole 202 and the rounded key head 302, further enhancing the blind opening effect. (The protruding cylinder cap 201 is completely different from the market size; the conventional size is below 2.5mm or flush with the chamfered edges 4 of the gourd lock shell.) The scissor-shaped key handle 301 is shaped like scissors, providing a solid grip and appropriate force when turning the lock cylinder. The conventional key head is a flat right angle; the improved rounded surface facilitates blind insertion into the lock cylinder hole and reduces the risk of injury or puncturing pockets when carrying it. The injection-molded handle 6, made of PC material, is 2.0mm higher than the scissor-shaped key handle 301, improving wear resistance. In cold regions, PC material has a better temperature barrier effect than pure metal, making it widely used in low-temperature areas. The anti-drilling pin 7, made of alloy material, ensures anti-pry and anti-drilling performance.
