Description

One kind work quick locking structure of head

Technical field

The utility model is related to burnisher technical field, and in particular to one kind work quick locking structure of head.

Background technology

The burnisher structures such as the mop and glass brush that now we use at present are fairly simple, are generally divided into two kinds Structure, one kind is work head and main rod body is fixed connection structure, and it promotes stress preferably, but can not carried out when in use Angle switches, more difficult for the site anteseptic such as narrow regions or furniture bottom；It is another to be hinged for work head with main rod body Attachment structure, its work head can do free rotation relative to main rod body, in the case where ensureing work head and face fit-state to be cleaned, Main rod body can be rotated freely, facilitated and cleaned, but its multivariant rotation formula, when in use, often inconvenient Fixed angle carries out stress, when especially clearing up ground, promotes more inconvenient, a kind of product is now lacked at present, it is enabled to Work head is with mobile jib attachment structure in lockup state and rotary state two states free switching.

Utility model content

(1) technical problem to be solved

In order to overcome prior art not enough, it is proposed that one kind work quick locking structure of head, its enable to work head with Both main rod bodies relativeness free switching between both fixed and universal rotational states, convenient multi-functional is used.

(2) technical scheme

The utility model is achieved through the following technical solutions：The utility model proposes one kind work quick locking knot of head Structure, including T-shaped work head, main rod body and sleeve pipe lock, the top of the T-shaped work head includes a connecting rod, the connecting rod End, which spins, is fixed with a universal joint, and the other end of the universal joint and main rod body bottom spin fixation, and described sleeve pipe lock tube is set It is provided with main rod body bottom and in the middle part of main rod body above and below a shaft shoulder that can be spacing to sleeve pipe lock progress, described sleeve pipe lock The side at two ends is respectively arranged with a locking hole, and one is respectively arranged with positioned at the main rod body of shaft shoulder bottom and the side of connecting rod Can inlay card in the spring card bead in locking hole.

Further, the connecting rod and universal joint are cylindric and both external diameters are respectively less than the internal diameter of sleeve pipe lock, Sleeve pipe lock can be on connecting rod and universal joint surface slidably.

Further, the inwall that described sleeve pipe is locked prolongs its length direction and is provided with least one groove, the main rod body Lateral surface is provided with strip projected parts corresponding with sleeve pipe lock indent groove location, and described sleeve pipe lock can pass through groove strip projected parts edge The strip projected parts of mobile jib external surface are freely up and down slided.

Further, the following span access location length of the main rod body shaft shoulder locks length not less than sleeve pipe.

(3) beneficial effect

The utility model has the advantages that relative to prior art：

A kind of work quick locking structure of head that the utility model is mentioned, it can be locked by pull sleeve pipe up and down so that T Shape work head can not only keep stationary state with main rod body, while can also rotate relatively freely, free switching mode is simple, It is adapted to multiple use.

Embodiment

In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain The utility model, is not used to limit the utility model.

A kind of work quick locking structure of head as depicted in figs. 1 and 2, including T-shaped work first 1, main rod body 2 and sleeve pipe Lock 3, the top of the T-shaped work first 1 includes a connecting rod 11, and the end of connecting rod 11, which spins, is fixed with a universal joint 4, institute The other end and the bottom of main rod body 2 for stating universal joint 4 spin fixation, and described sleeve pipe lock 3 is sheathed on the bottom of main rod body 2 and in main rod body 2 middle parts are provided with one can lock the spacing shaft shoulder 21 of 3 progress to sleeve pipe, and the side of the upper and lower ends of described sleeve pipe lock 3 is set respectively A locking hole 31 is equipped with, being respectively arranged with one positioned at the main rod body 2 of the bottom of the shaft shoulder 21 and the side of connecting rod 11 being capable of inlay card In the spring card bead 5 in locking hole 31.

Wherein, the connecting rod 11 and universal joint 4 are cylindric and both external diameters are respectively less than the internal diameter of sleeve pipe lock 3, Sleeve pipe lock 3 can be on connecting rod 11 and the surface of universal joint 4 slidably；The inwall of described sleeve pipe lock 3 prolongs its length direction and set It is equipped with least one groove 32, it is convex that the lateral surface of the main rod body 2 is provided with strip corresponding with sleeve pipe lock 3 inner groovy 32 position 22 are played, the strip projected parts 22 that described sleeve pipe lock 3 can be by the strip projected parts 22 of groove 32 along the outer surface of main rod body 2 are freely up and down slided It is dynamic；The shaft shoulder of main rod body 2 span access location length below 21 locks 3 length not less than sleeve pipe.

A kind of work quick locking structure of head that the utility model is mentioned, it is primarily directed to the mop now used at present And glass brush, our mops of the above, can be downward when we clear up spacious ground using mop as specific embodiment Promote sleeve pipe lock 3, sleeve pipe lock 3 is by strip projected parts 22 of the groove 32 on its interior along the outer surface of main rod body 2 to downslide It is dynamic, lock 3 until sleeve pipe and slide at the connecting rod 11 in T-shaped work first 1, now connecting rod 11 and connected universal joint 4 are fully located inside sleeve pipe lock 3, while sleeve pipe locks the inlay card of locking hole 31 of 3 bottoms in the Spring Card positioned at the side of connecting rod 11 On pearl 5, the relative position of sleeve pipe lock 3 is fixed, and now T-shaped work first 1 is fixed with the relative position of main rod body 2, and whole mop can be with Very easily carry out floor cleaning.

When we are cleared up using mop is located at furniture bottom ground, sleeve pipe lock 3 can be stirred upwards, sleeve pipe lock 3 is with connecting Spring card bead 5 at extension bar 11 departs from, sleeve pipe lock 3 upward sliding while, positioned at T-shaped work first 1 on connecting rod 11 and Universal joint 4 spins off out of sleeve pipe lock 3, while the bullet that the locking hole 31 that sleeve pipe locks 3 upper sides can be with the side of main rod body 2 The inlay card of spring card bead 5 is fixed, and sleeve pipe is locked 3 relative positions and fixed, and T-shaped work first 3 can be by universal joint 4 relative to main rod body 1 It is any to rotate, it can facilitate and T-shaped work first 3 is stretched into narrow regions be cleaned.

Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality New spirit and scope are defined.On the premise of the utility model design concept is not departed from, this area ordinary person couple The all variations and modifications that the technical solution of the utility model is made, all should drop into protection domain of the present utility model, this reality With new claimed technology contents, all record in detail in the claims.
