Embodiment

Referring to figs. 1 through Fig. 4, the utility model slotted round nut embodiment is described further.

As shown in Figures 1 to 4, a kind of fluting 3 round nuts, comprise nut body 1 and be located at nut body 1 one end and with the bulge loop 2 of the coaxial setting of nut body 1, described nut body 1 comprises internal thread 11, on the outer peripheral surface of nut body 1, circle distribution has fluting 3, described fluting 3 comprises bottom surface 31, the first side wall 32 and the second sidewall 33, described the first side wall 32 is provided with the first lubricating structure 4, described the first lubricating structure 4 comprises the first groove 41, described internal thread 11 is provided with the first through hole 42 with the first groove 41 conductings, the opening of described the first groove 41 is embedded with first and adds oil clot 43, the bottom of described the first groove 41 is connected with the first elastic component 44, described the first elastic component 44 connects first and adds oil clot 43,

In described the first groove 41, be provided with lubricant oil (it should be noted that herein, on the described first surface that adds oil clot 43, the sealability between rubber coating reinforcement and the first groove 41 can be set, and the oil hole with the first groove 41 conductings is set on nut body 1, realization supplements the first groove 41 interior lubricant oil, and the present embodiment repeats no more; Described the first elastic component 44 can be various elastic materials, the preferred spring of the present embodiment).

Opening at described the first groove 41 arranges the first lubricating structure, can utilize described the first lubricating structure, when screwing or dismantling described fluting 3 round nuts, utilize the end of clamp in rotation, press described first and add oil clot 43, thereby the lubricant oil in the first groove 41 is passed through to the first through hole 42, from internal thread 11, flow out, thereby realize, lubricate, do not need manually to utilize extra instrument to refuel, lubricate, simply, practicality, efficiency is high.

Described first adds oil clot 43 for the slug of rectangular configuration, the first sidewall that adds oil clot 43 is provided with dovetail groove 45, the sidewall of described the first groove 41 is provided with the projection 46(suitable with described dovetail groove 45 and it should be noted that herein, described first adds oil clot 43 also can form for other materials, as vulcanite, polymer etc., the present embodiment is considered described in assembling and is opened in the process of circular groove nut, first adds the required stressed factor of oil clot 43, preferably hard metal material forms, and concrete material repeats no more; In addition, between the projection 46 in the present embodiment and the bottom of groove, leave gap, directly do not extend to the bottom of groove).

The projection 46 that dovetail groove 45 is set and coordinates with described dovetail groove 45, can limit described first and add the movement position of oil clot 43 when pressurized, thereby prevent that described first adds the edge of oil clot 43 and the sidewall of described the first groove 41 is swiped, affect the first sealing adding between oil clot 43 and described the first groove 41, the phenomenon such as even get stuck, affects using effect.

Described the first lubricating structure 4 is also provided with for preventing that first adds the limit structure that oil clot 43 drops out the first groove 41.

Can prevent that first adds oil clot 43 and drop out the first groove 41 because of the support of elastic component, thereby guarantee practicability and the working life of described fluting 3 round nuts.

Described limit structure comprises limiting board 47, and described limiting board 47 is provided with first and adds the bottom of oil clot 43 and between projection 46 and the bottom of the first groove 41.

Utilize described limiting board 47, can add oil clot 43 because the support force of the first elastic component 44 is dorsad during the first groove 41 motion described first, conflict projection 46, thus prevent that described first adds oil clot 43 and drop out.

Described the second sidewall 33 is provided with second lubricating structure 5 identical with the first lubricating structure 4 structures;

On described nut body 1, comprise some flutings 3, described respectively fluting 3 is equipped with first, second lubricating structure 5.

The second lubricating structure 5 is set, can when screwing and dismantle, described fluting 3 round nuts all can make internal thread 11 places be lubricated, and, a plurality of first, second lubricating structures 5 are set, but also can be according to actual needs, only select a pair of or some cross-notchings 3 to install, dismantle, repeat, repeatedly use, or control the use amount of lubricant oil.

The above makes preferred implementation of the present utility model, does not depart from for the person of ordinary skill of the art under the prerequisite of the utility model principle, can also make some modification and improvement, and these also should be considered as protection domain of the present utility model.
