Abstract

The utility model relates to a key structure with higher safety, which comprises a key consisting of a key handle and a key body. The key structure is characterized in that a bit groove is arranged on the surface of the key body, and bits are arranged on side walls of the bit groove and perpendicular to the same. Bits of the key are concealed in the bit groove skillfully, no bits are protruded or exposed from the integral key, the surface of the integral key body is evened completely, the bits are protected effectively and prevented from being abraded, and the service lives of the bits are prolonged. Besides, the bit structure of the key is much different from that of an existing key and is novel and scientific in design, thereby being favorable for lock product manufacturers to manufacture lock products with higher safety and better antitheft performance.

Description

The better Key structure of a kind of safety

Technical field

The utility model relates to a kind of Key structure.

Background technology

At present, the common key that arrives commonly used of people, the structure of its spoon tooth mainly contains two kinds: a kind of is two sides that spoon tooth is arranged at key spoon body, another kind is that a spoon tooth is and vertically is vertically installed in key spoon body surface.The deficiency of these two kinds of key tooth structures is: because a spoon tooth all is to show especially fully and be exposed to a spoon body surface; Make key be placed through in the key-ring; Long-term friction each other and collision between the various keys; Be easy to cause the wearing and tearing of spoon tooth, and then the smoothness when having influence on key unlocking, and the application life of whole lock.In addition, because the safety of lock and the key tooth structure of key are closely-related, and the key spoon tooth of present various types of lock all is confined on these two kinds of outmoded structures, thereby to a certain extent, has seriously influenced the theftproof performance and the security performance of lock product.

The utility model content

The purpose of the utility model is to solve above-mentioned deficiency, and a kind of key tooth structure modern design, science are provided, and a spoon tooth is difficult for being worn long service life, the better Key structure of safety.

The technical scheme of the utility model is achieved in that

The better Key structure of a kind of safety comprises by spoon handle and the key body that constitutes of spoon body, and its characteristics are to offer alveolus on the surface of said spoon body, on the groove sidewall of alveolus, are provided with a spoon tooth, and this spoon tooth is on the groove sidewall perpendicular to alveolus and is provided with.

In order further to improve the security performance of key, the groove sidewall of above-mentioned alveolus is provided with two layers of spoon tooth up and down.

The technique effect of the utility model:

Because being employed in the spoon body surface of key is provided with alveolus and is being provided with on the groove sidewall of alveolus perpendicular to the key tooth structure on its groove sidewall; Make the utility model through dexterously the spoon tooth of key being hidden in the alveolus, the whole piece key does not have protruding to come or outstanding spoon tooth whole spoon body surface leveling fully fully; Not only protected the spoon tooth effectively; Spoon tooth can be worn, prolong the life-span of its use, but also key tooth structure that a kind of structure is different from existing key fully is provided for the lock product; Novel in design, the science of key tooth structure produces that safety is better, the better lock product of theftproof performance thereby help locking production producer.

Below in conjunction with accompanying drawing the utility model is further described:

Description of drawings

Fig. 1 is the Facad structure sketch map of the utility model.

Fig. 2 is the utility model Figure 1A-A direction sectional structure sketch map.

The specific embodiment

Like Fig. 1 and shown in Figure 2, the better Key structure of the described a kind of safety of the utility model comprises the key body 1 that is made up of spoon handle 11 and spoon body 12, and this and general key product composition are basic identical.In order to realize the utility model purpose, Fig. 1 and shown in Figure 2 and for example offers alveolus 13 on the surface of said spoon body 12, on the groove sidewall of alveolus 13, is provided with spoon tooth 14, and this spoon tooth 14 is on the groove sidewall perpendicular to alveolus 13 and is provided with.In order further to improve the security performance of key, as shown in Figure 2, on the groove sidewall of alveolus 13, be provided with two layers of spoon tooth 14 up and down, improve its security performance and theftproof performance through increasing spoon tooth 14 complexity.In addition, comparatively smooth and easy, as shown in Figure 1 for making spoon body 12 in inserting the lockhole process, become horn-like groove port one 5 at the groove port of alveolus 13.

In the present embodiment, Fig. 1 and structural concept shown in Figure 2 are the embodiments that is provided with alveolus 13 and spoon tooth 14 for single face.In practical application, two faces that can also be chosen in spoon body 12 all are provided with alveolus 13 and are embodiment with spoon tooth 14.
