CN2322538Y - Telescopic rod for mop - Google Patents

Abstract

The utility model relates to a telescopic rod for a mop. A first rod of a mop head is integrated with a hollow joint, and the outer part and the inner face of the joint respectively form outer threads and a set of keys. Both ends of a casing tube respectively form a first and a second extension pipes, key grooves tabled mutually are formed on the first extension pipe corresponding to the keys, and the second extension pipe cam be arranged in the inner part of one end of a second rod. The inner part of a rotating joint is provided with inner threads which are just mutually screwed with outer threads, and the rotating joint can be integrated on the end part of the second rod. When the length is changed, only the second rod and a third rod can be forced to relatively ratchet.

Description

The mop expansion link

The utility model relates to a kind of mop expansion link, mainly be to change the length of mop expansion link and when rotating the 3rd bar and mophead relatively when desire, rotation relative between second bar and the 3rd bar is got loose, can not make between second bar and the mophead generation phenomenon that gets loose improperly.

Because on the indoor floor, drop accidentally in ground dirt in dust in air or because of people, after dirt being stained with stick on the floor through trampling of people again, people can or be stained with sticking dirt and clean out after must wanting mat one mop to drag, draw in front and back on the floor ground dust.

And floor manner of cleaning up commonly used at present is that mat one mop carries out, and as shown in Fig. 5,6, promptly is a kind of traditional Mop structure figure, and the structure of this mop includes:

One mophead 60, including one can be for the sponge or the rag head on cleaning ground, has one first bar 61 on this mophead 60, side in first bar 61 is provided with the joint 62 that an inside has screw thread, in the in addition side of joint 62 is to screw togather second bar 64 with screw rod 63 relatively, then be provided with diameter three bar 65 bigger in the in addition side of second bar 64, be connected between second bar 64 and the 3rd bar 65 and have an anchor tip 66 than second bar 64;

And second bar 64 and the 3rd bar 65 are all the round bar body of hollow form, and the end of second bar 64 can penetrate in the 3rd bar 65, and has eccentric structure 67 in the end of second bar 64, when rotating second bar 64 and the 3rd bar 65 relatively, eccentric structure 67 on second bar, 64 ends can or unclamp 65 relative lockings of second bar 64 and the 3rd bar, when rotating with clockwise direction in the end of the 3rd bar 65 under the normality is the direction of locking, otherwise, if when rotating then serve as the direction of removing locking with counterclockwise direction, but, when said structure uses in reality, but have following shortcoming and remain to be improved:

When the length of conversion expansion link, the user tends to one and holds the 3rd bar 65, other holds mophead 60 places, when rotating the 3rd bar 65 with the releasing locking state, if be that locking is when tightly killing then can't be outwarded winding between second bar 64 and the 3rd bar 65, can make on the contrary and relatively be rotated between joint 62 and the screw rod 63 and get loose, but anchor tip 66 places between second bar 64 and the 3rd bar 65 are but because of can not removing the state of locking, and can't reach the purpose of collapsing length.

The purpose of this utility model is to overcome the defective that existing mop expansion link is difficult for the conversion length of telescopic bar, and a kind of mop expansion link that makes things convenient for the length of conversion expansion link is provided.

The purpose of this utility model is achieved through the following technical solutions: a kind of mop expansion link comprises: a mophead, has one first bar in the one side, side in first bar is provided with a joint, end in addition in second bar articulates bigger anchor tip and the 3rd bar of a diameter, in between end of second bar and the 3rd bar, have an eccentric structure, wherein:

End outside in joint is formed with external screw thread, is formed with several keys in joint inside,

A sheathed inside has the swivel joint of internal thread on second bar, and the external screw thread on swivel joint and the joint screws togather mutually,

In between second bar and joint, be provided with an inner sleeve, extend outwardly in an end of inner sleeve and to form first extension, on first extension, form several keyways, can be chimeric mutually between each keyway and the key be one, can not rotate relatively between first bar and second bar guaranteeing.

In above-mentioned mop expansion link, the in addition end of inner sleeve can form second extension, and second extension can mutually combine with second bar and is one.

The utility model compared with the prior art advantage and good effect is very obvious.By above technical scheme as can be known, the utility model has following advantage at least:

But the utility model is one group of set key 14 on the mat joint 12 mainly, an end that makes joint 12 is in conjunction with first bar 11, in second bar, 20 upper sleeve throughs one swivel joint 21 is arranged, and on the end of second bar 20 in conjunction with an inner sleeve 30, can be one with key 14 mutual chimeric the setting firmly on the joint 12 in the keyway on the inner sleeve 30 33, during use, when rotating mutually between the 3rd bar 50 and the mophead 10, cause first bar 11 and 20 on second bar are the forms that sets firmly mutually to one, so only can cause relative rotation rotation between the 3rd bar 50 and second bar 20, thereby be convenient to change the length of expansion link.

Further specify specific structural features of the present utility model and purpose below in conjunction with accompanying drawing:

Fig. 1 is the three-dimensional appearance exploded view of the utility model mop expansion link;

Fig. 2 is a sectional perspective exploded view of the present utility model;

Fig. 3 is that part of the present utility model is in conjunction with cutaway view;

Fig. 4 is that the utility model is by the cutaway view that is cut among Fig. 3;

Fig. 5 is the three-dimensional appearance exploded view of conventional mop expansion link;

Fig. 6 is that the part of conventional mop expansion link is in conjunction with cutaway view.

The utility model is a kind of mop expansion link, and as shown in Fig. 1,2, the utility model includes:

Side in mophead 10 has one first bar 11, is provided with a joint 12 in a side of first bar 11, is formed with external screw thread 13 in an end outside of joint 12, is formed with one group of relative key 14 in addition in the inside of joint 12;

One second bar 20, a sheathed inside has the swivel joint 21 of internal thread on second bar 20, and this swivel joint 21 can screw togather mutually with the external screw thread 13 on the joint 12;

Between second bar 20 and joint 12, be provided with an inner sleeve 30, formation first extension 31 and second extension 32 extend outwardly respectively in the two ends of inner sleeve 30, second extension 32 can be incorporated on second bar 20, form in addition one group of relative keyway 33 on first extension 31, this group keyway 33 can be chimeric mutually with key 14 is one;

And articulate bigger anchor tip 40 and the 3rd bar 50 of a diameter in the in addition end of second bar 20, and between end of second bar 20 and the 3rd bar 50, have an eccentric structure equally, because of it is a traditional structure, do not repeat them here.

When using after the combination of mat said structure (as shown in Fig. 3,4), after the inner sleeve 30 with keyway 33 and one group of key 14 of joint 12 are chimeric mutually, mat swivel joint 21 lockings more at this moment, promptly can make between first bar 11 and second bar 20 to be situation about mutually combining to one.

When desire changes the length of mop expansion link, that is people can grip on the other hand as the 3rd bar 50 among Fig. 1, hand grips mophead 10 places in addition, when relatively rotating, because of being rotated for one because of the relation of key 14 and keyway 33 interfixes between first bar 11 and second bar 20, thereby be bound to make rotation relative between second bar 20 and the 3rd bar 50 so that second bar 20 and 50 on the 3rd bar are loosening state, can the stretching mop the contract this moment length of boom can be for the purpose of conversion length of telescopic bar to reach.
