Description

Buckle with improved structure

The utility model belongs to buckling parts, in particular to a buckle with improved structure.

The commonly used general buckle, as shown in Figure 1, is composed of a female buckle 10 and a male buckle 11, wherein the female buckle 10 is made hollow, and a clamping gap is integrally formed at an appropriate place on both sides of the buckle 101, while the male buckle 11 is integrally formed with two symmetrical clamping parts 111, when fastened and connected, the male buckle 11 can be correspondingly worn on the female buckle 10 by using the two clamping parts 111 provided on it. It is hollow inside, and is buckled on the clamping gap 101 provided by the female buckle 10 through the hooks 112 formed at the ends of the clamping parts 111, so that they are connected to each other as a whole without loosening and separating. Reliable, as long as you accidentally touch each locking part 111, it may cause each locking part to break away from the locking position, that is, once each locking part 111 breaks away from the locking position, it will immediately cause the female buckle 10 and The separation of the male buckle 11, as long as the female buckle 10 loses connection with the male buckle 11, the articles carried by people will be lost from the bag, causing unnecessary losses.

The purpose of this utility model is to provide a buckle with an improved structure, so that the fastening of the male and female buckles can add a locking structure to prevent disengagement, so as to ensure the fastening effect, and adjust the elastic force of the spring to adapt to different occasions. snap fit required.

The utility model adopts the following technical solutions:

The buckle with improved structure of the utility model includes: a female buckle, which is generally hollow, and has a clamping gap integrally formed at appropriate places on both sides of the buckle; a male buckle, on which two symmetrical clamps are integrally formed. The two clamping components can be used to correspondingly pass through the hollow inside of the female buckle, and with the help of the clasps formed at the ends of the clamping components, they can be fastened one by one to the clamps set on the female buckle. In order to make them connected with each other; the male buckle has two top parts integrally formed between the two clamping parts; the hollow interior of the female buckle is integrally formed on the wall with a guide rail and a bottom In addition to a limiting part, a pressing device is installed at an appropriate place on the bottom surface. The pressing device is composed of a shaft, a compression spring and a push-pull part. The shaft is fixed on the female buckle. The bottom is just inside the restricting part, the compression spring is sleeved on the shaft, and the pushing part can be provided with a guide part on the side corresponding to the guide rail on the inner wall of the female buckle.

The buckle with the improved structure of the utility model is provided with a top part between the two clamping parts of the male buckle, and a guide rail and a limiting part are arranged on the hollow inner wall of the female buckle, so that the fastening of the male and female buckles is increased by one step. The clamping structure to prevent detachment ensures the fastening effect, and the elastic force of the spring can be changed arbitrarily to meet the fastening effect required by various places.

Describe embodiment below in conjunction with accompanying drawing:

Referring to Fig. 1 to Fig. 5, the buckle with the improved structure of the utility model is composed of a female buckle 2 and a male buckle 3, wherein the female buckle 2 is generally hollow, and there are appropriate places on both sides of the buckle. There is a clamping notch 21 integrally formed, except that a guide rail 22 is integrally formed on the wall surface and a restricting part 23 is provided below the hollow interior of the female buckle 2, and a pressing device 24 is installed at an appropriate place on the bottom surface. The pressing device 24 is composed of a shaft 241, a compression spring 242 and a push-pull part 243, wherein the shaft 241 is fixed on the bottom of the female buckle 2, just inside the limiting part 23, and the compression spring 242 It is sleeved on the shaft rod 241, and the push-pull part 243 is also sleeved on the shaft rod 241 after the compression spring 242. In order to make the push-pull part 243 displace along a certain route, the push-pull part 243 A guide part 245 can be provided on the side where the guide rail 22 is provided on the inner wall of the corresponding box 2, and the guide part 245 is installed and inserted into the guide rail 22, and under mutual guidance, the displacement action of the push-pull part 243 can be ensured. precise.

The male buckle 3 has two symmetrical clamping parts 31 integrally formed on it, and the two clamping parts 31 can be used to correspondingly pass through the hollow interior of the female buckle 2, and each clamping part 31 can be used to The clasps 311 formed at the end are fastened one by one on the clamping gap 21 provided by the female clasp 2 so that they are connected to each other as a whole, and the male clasp 3 is integrated between the two clamping parts 31 There are two top making parts 32 formed, which can contact each holding part 31 one by one at an appropriate time during the action.

The working principle of the utility model is that when the male buckle 3 and the female buckle 2 are fastened together, the male buckle 3 can be buckled one by one on the hooks 311 formed on the ends of the clamping parts 31 on the female buckle 2. Clamp the notch 21 to make it connected to each other as a whole. Unlike the conventional buckle, when the male buckle 3 penetrates into the female buckle 2 to a predetermined depth, the two top parts 32 touch the female buckle 2 and tighten tightly. When the push-pull part 243 of the device 24 is affected by the inclination of the surface of the push-pull part 243, the two push-up parts 32 will be gradually pushed apart, and slightly bent and displaced to both sides respectively. 2. When the fastening position is reached, the two top parts 32 can also correspondingly abut against each fastening part 31 at the same time, which ensures the fastening effect of the buckle of the present utility model. Even if it is touched at this time, due to the With the effective support and abutment of the two pushing parts 32, each holding part 31 is not easy to fall off and separate, and the separation between each holding part 31 and the holding gap 21 will not be caused. The spring of the buckle of the present utility model The elastic force can be changed arbitrarily to adapt to the fastening effect required by various places.

In summary, the buckle with improved structure of the utility model has a simple and reasonable structural design, overcomes the defects of conventional buckles, and achieves the expected design purpose.
