Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
The utility model embodiment one as shown in Figures 1 to 5, a kind of bat lid chain connection structure, syndeton 30 is fixedly attached on bat lid 20, chain 10 is connected with bat lid 20 by syndeton 30, described syndeton 30 comprises connector 31 and the holding firmware 32 that is provided with gradual change opening 311, described holding firmware 32 is fixedly attached with connector 31, and one end of chain 10 connects and fixes with described holding firmware 32 through described gradual change opening 311.
In the present embodiment, described chain 10 is pelletron, pearl spaced apart on pelletron, described chain element is pearl, or chain 10 also can be loop chain, and loop chain is made up of the collar be mutually socketed, described chain element is the collar, can also be other shapes as cylindrical, oval chain element, the shape of chain element is not as limit.
In the present embodiment, be provided with the container cavity 313 of at least one pearl holding chain 10 below the gradual change opening 311 of connector 31, one end of chain 10 is passed described gradual change opening 311 and is stretched into described container cavity 313 and holding firmware 32 clamping.
In the present embodiment, described gradual change opening preferably adopts the horn shape by inner arc transition outward.The large mouth of the gradual change opening 311 of described connector 31 is greater than the chain spacing L2 between two adjacent chain elements to the arc length L1 between osculum, also be, in the present embodiment, when chain 10 is subject to along gradual change opening 311 radial pull, on the circular arc having at least two adjacent beads to drop between described large mouth to osculum, so, have two pearls simultaneously stressed, increase lifting surface area, chain is not easy to be torn, longer service life.
In the present embodiment, described connector 31 is fixed on to be clapped on lid 20, and holding firmware 32 inserts described container cavity 313 and is connected on container cavity 313 sidewall.Holding firmware 32 side is provided with stuck point 322, connector 31 is provided with hole clipping 312 in the position of the stuck point 322 of corresponding holding firmware 32, be connected with hole clipping 312 fixing of connector 31 by the stuck point 322 of holding firmware 32 in holding firmware 32 built-in connector 31, chain 10 penetrates from the gradual change opening 311 of connector 31, holding firmware 32 loads in connector 31 and chain clamping from the side, and at least one pearl of chain 10 is connected in container cavity 313 by holding firmware.In the present embodiment, the shape of described holding firmware 32 is U-shaped, and the distance L3 between the inwall of U-shaped both sides is less than the width of chain element, also namely, L3 is less than the diameter of pearl, and such pearl penetrates the rear below that just can be stuck in holding firmware 32 from the opening of U-shaped, easy for installation, simply.
As shown in Figure 6, Figure 7, the difference of itself and embodiment one is the utility model embodiment two:
In the present embodiment, described holding firmware 32 is fixed on to be clapped on lid 20, cavity 321 is provided with in described holding firmware 32, a kerf 323 is provided with above cavity 321, the width of this otch 323 is less than the diameter of the pearl of chain 10, the gradual change opening 311 of connector 31 is communicated with the cavity 321 of holding firmware 32 by described otch 323, connector 31 holding firmware 32 to be enclosed within described container cavity 313 and with the clamping of holding firmware 32 phase.By the gradual change opening of one end of chain 10 through connector 31, again at least one pearl of chain 10 is loaded from otch 323 side in the cavity 321 of holding firmware 32, the otch 323 of holding firmware 32 ensures that at least one pearl of chain 10 is connected in the container cavity 313 of connector 31, and connector 31 to be fixed with holding firmware 32 by buckle and is connected.
Embodiment one of the present utility model and embodiment two are by the container cavity 313 that at least one pearl of chain 10 is connected to connector 31 by holding firmware 32 and the structure of being stretched out by the gradual change opening 311 of connector 31, gradual change opening 311 can make chain 10 when being subject to the radial load along gradual change opening 311, chain 10 will along gradual change opening 311 arc transition, be not easy to be torn, extend chain application life, prevent chain 10 to be wrapped in simultaneously and clap on lid 20, clap in lid process can not cause bite in pull-up, also can not cause and clap lid 20 because chain 10 shortens and cover not tight, without the need to worrying to there is seepy question.
In addition, not auxiliary hook on chain 10 of the present utility model, product installation difficulty is reduced greatly, and without the need to by other instruments, simultaneously connector 31 makes chain 10 simultaneously and claps lid 20 and do not produce direct contact wear, chain 10 through after the gradual change opening 311 of connector 31 with holding firmware 32 clamping, then connector 31 and holding firmware 32 are fixed just installation, simple to operate, saving time cost is connected firmly simultaneously and not easily pulls.
Although specifically show in conjunction with preferred embodiment and describe the utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
