Background technology
Waistband is daily life articles for use, waistband is in the process of using, by belt buckle, waistband is loosened, tighten, waistband is played a role, therefore, belt buckle has crucial effect for waistband, and can whether belt buckle use to facilitate and apply, be accepted and like to have great importance for waistband.In the last few years, automatic waistband button was welcomed by the people, and development rapidly.
In correlation technique, automatic waistband button comprises main body, back seat, slip limiting plate, connecting rod and spanner, and wherein, main body is groove shape structure, and its two relative sides have through hole, for belt, passes, and bottom is provided with magnet; Main body and slip limiting plate are hinged, and the connecting axle being hinged is parallel to the side that has through hole, and slip limiting plate is made with ferrous material, and under the effect of magnet, slip limiting plate is adsorbed in main body; One end of the connecting axle being hinged is provided with spanner.The side that one end of back seat and main body have through hole is hinged, and the other end of back seat is connected with waistband.In use, waistband passes main body, and through between slip limiting plate and main body, but the magnetic force between slip limiting plate and main body still exists, and therefore, waistband is fixed position between slip limiting plate and main body.While untiing waistband, pull spanner, spanner drives slip limiting plate to depart from main body, and waistband skids off main body.
Because above-mentioned belt buckle structure is complicated, use loaded down with trivial details, the situation that often causes user normally to use.
The specific embodiment
Below by specific embodiment, also by reference to the accompanying drawings the utility model is described in further detail.
Referring to Fig. 1 and Fig. 2, a kind of belt buckle, comprising: main body 1, back seat 2, slip limiting plate 3 and spring 4, and main body 1 is rotationally connected with back seat 2; One end of slip limiting plate 3 and back seat 2 are rotationally connected, and when the angle between back seat 2 and main body 1 is 180 °, the other end of slip limiting plate 3 withstands through the waistband of main body 1 (not shown in FIG.) (referring to Fig. 4); Spring 4 is between back seat 2 and slip limiting plate 3, and an external part 7 of spring is fixedly connected with slip limiting plate 3, and another external part 8 of spring is fixedly connected with back seat 2.
Adopt the belt buckle of said structure, when waistband penetrates main body, when waistband produces certain pressure to slip limiting plate, slip limiting plate can produce certain pressure to spring under the effect of pressure, after the spring effect of being under pressure, can produce bounce, act on slip limiting plate, thereby slip limiting plate is under the bounce effect of spring, and waistband is against in main body tightly, realizes the locking of waistband.When waistband penetrates belt buckle locking, the angle between back seat and main body is 180 ° (referring to Fig. 5).
While unclamping waistband, as long as keep main body to maintain static, a little upwards lift belt buckle, slightly firmly clockwise rotate back seat simultaneously, strengthen the distance between slip limiting plate and main body, thus slip limiting plate is separated with waistband, realize waistband and unclamp.
The belt buckle that this use new embodiment provides, by spring being set between slip limiting plate and back seat, makes slip limiting plate rely on the bounce of spring that waistband is withstood in main body.Realize the belt buckle of locking function with the principle of utilizing magnet in prior art and compare, not only simple in structure, and also easy to use, be not easy to cause the phenomenon that cannot normally use.
Particularly, spring external part 7 is riveted with slip limiting plate 3.Mode by riveted joint makes an external part of spring be fixedly connected with slip limiting plate, easy to operate, and processing is simple.As it may occur to persons skilled in the art that, between external part 7 of spring and slip limiting plate 3, can also wait other modes that are fixedly connected with to be connected by welding.
Particularly, another external part 8 of spring and back seat 2 riveted joints.Mode by riveted joint makes an external part of spring be fixedly connected with back seat, easy to operate, and processing is simple.As it may occur to persons skilled in the art that, between another external part 8 of spring and back seat 2, can also wait other modes that are fixedly connected with to be connected by welding.
Particularly, the main body of spring 4 is positioned at back seat 2 on the side of slip limiting plate 3 (referring to Fig. 2).The power that spring is produced radially works to slip limiting plate 3.In main body, penetrate after waistband, slip limiting plate, under the effect of elastic force, can, by waistband being stuck in main body tightly, be realized the locking of waistband.
As it may occur to persons skilled in the art that, the belt buckle that the utility model embodiment provides, wherein, spring 4 can also utilize its axial elastic force to work to slip limiting plate 3.In main body, penetrate after waistband, slip limiting plate, under the effect of elastic force, can, by waistband being stuck in main body tightly, be realized the locking (referring to Fig. 3) of waistband.
Particularly, the angle between spring external part 7 and slip limiting plate is 0 °.Such structure is conducive to spring to be exerted pressure, the elasticity of performance spring, otherwise, being conducive to slip limiting plate and bringing into play preferably elasticity, the head of while due to the external part of spring is not directly to prop up slip limiting plate, is conducive to protect slip limiting plate, extends its service life.
Further, the belt buckle that the utility model embodiment provides, also comprises connecting rod 5, and main body 1 is connected by connecting rod 5 with back seat 2, and spring is placed on (referring to Fig. 2) on connecting rod 5.Spring is placed on connecting rod, has eliminated the space that spring takies between back seat and slip limiting plate, make belt fastener seem more attractive in appearance.
Particularly, slip limiting plate 3 is placed on connecting rod 5, and the external part that spring 4 is connected with slip limiting plate 3 is fixed on slip limiting plate 3 on the side of back seat 2, props up slip limiting plate 3, limits its rear-facing seat 2 and rotates (referring to Fig. 2).
As those skilled in the art expect, for slip limiting plate can be fixedly connected with an external part of spring, can also can on slip limiting plate, fix a coil by the mode of riveted joint, an external part of spring is connected with slip limiting plate through coil.
Slip limiting plate 3 can directly be fixedly connected with and realize being rotatably connected between slip limiting plate and back seat with an external part 7 of spring, also can be by being directly connected on back seat, and realization is rotatably connected with back seat.The belt buckle that the utility model embodiment provides, is placed on slip limiting plate on connecting rod, realizes being rotatably connected between slip limiting plate and back seat., for fear of slip limiting plate, come off, the external part that spring is connected with slip limiting plate is fixed on slip limiting plate on the side of back seat, props up slip limiting plate meanwhile, limits its rear-facing seat and rotates.Such structure can increase slip limiting plate in the stressed adaptability of different directions, when user is often movable, is conducive to protect slip limiting plate, extends its service life.
Particularly, slip limiting plate 3 is set to arced terminus 6 away from one end of back seat 2.Slip limiting plate can directly contact with waistband away from the termination, one end of back seat, if this end is designed to linear, termination is sharper; easily cause waistband to receive damage, and this end is designed to arc, can make termination passivation; be conducive to protect waistband, extend the service life of waistband.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
