Description

Waistband buckle Technical Field The utility model relates to the technical field of waistbands, in particular to a waistband buckle. Background The waistband buckle is a key component used for connecting two ends of the waistband and realizing the functions of fixing and adjusting tightness, and has the core effects of ensuring that the waistband is kept stable when being worn, and simultaneously facilitating a user to quickly adjust the length according to requirements. Conventional belt buckles mainly adopt a needle buckle or a ratchet mechanism, however, the structure has a plurality of defects in actual use: (1) The pin buckle depends on the cooperation of the contact pin and the buckling hole to realize fixation, has low adjustment precision, needs frequent plugging and pulling, is easy to loosen due to abrasion after long-time use, and has the advantages that the ratchet mechanism can realize continuous adjustment, but a specific part needs to be pressed or stirred during release, the operation is complex, and unlocking difficulty or unexpected loosening can occur due to fatigue of the clamping teeth. (2) Parts such as a plurality of springs, latches and the like are integrated in the part ratchet or the multifunctional buckle, so that the assembly difficulty and the manufacturing cost are increased, the whole failure is possibly caused by part abrasion, and the service life is reduced. Along with the improvement of the wearing experience requirements of users, the belt buckle which is convenient to operate, reliable in structure and accords with human engineering is developed and becomes an industry pain point. In the prior art, a solution for realizing quick fastening and release by a simple mechanical structure and simultaneously taking cost control into consideration has not yet appeared. Disclosure of utility model The utility model aims to provide a belt buckle, so as to solve the problems in the prior art and improve the operation convenience and the structural reliability of the belt buckle. In order to achieve the above object, the present utility model provides the following solutions: The present utility model provides a belt buckle comprising: A base; The first end of the locking body is rotationally connected with one end of the base body, a passage for the waistband to pass through is formed between the locking body and the base body, the second end of the locking body is mutually far away from the first end, a stop tooth used for limiting the groove on the waistband is fixedly arranged at one side of the second end of the locking body, which is close to the channel, and one end of the stop tooth, which is far away from the locking body, is far away from the first end of the locking body than the other end of the stop tooth; The first end of the lever is rotationally connected with one side, far away from the channel, of the second end of the locking body, a placing groove used for preventing the rear end of the waistband is formed between the lever and the locking body, a plurality of locking nails used for pressing the rear end of the waistband are fixedly arranged on one side, close to the placing groove, of the first end of the lever, the first end of the locking body can limit the middle of the lever, and the contact position of the first end of the locking body and the lever serves as a fulcrum of the lever. Preferably, the locking body is rotatably connected with the base body through a first connecting pin; the first end of the lever is rotatably connected with the locking body through a second connecting pin. Preferably, a limiting rod is arranged at the other end of the base body, and the limiting rod is used for limiting the waistband in the channel along the thickness direction of the waistband. Preferably, the substrate is frame-shaped. Preferably, the placement groove is located within the locking body. Preferably, the lever is plate-shaped, the locking pin is cone-shaped, and the tip of the locking pin is far away from the lever. Preferably, the number of the locking nails is 7, and all the locking nails are sequentially arranged along the width direction of the lever. Preferably, the limit rod is fixedly connected with the base body. Preferably, two ends of the limiting rod are respectively connected with the base body in a rotating way. Compared with the prior art, the utility model has the following technical effects: The belt buckle provided by the utility model has the advantages that through the innovative design of the lever mechanism and the stop teeth, the convenience, comfort and mechanical property of the belt are obviously improved. Compared with the traditional operation mode that the needle buckle needs to be repeatedly inserted and pulled and the ratchet buckle needs to press complex components, the utility model can finish the locking and releasing of the waistband by only pulling the lever with one hand, thereby greatly simplifying the operation steps, gr
