Description

The flexible rod structure improvement

The utility model relates to a kind of flexible rod structure improvement, be a kind of people of being convenient in use can be as required the length of regulating lever voluntarily.

Existing common bar is to be revolved mutually to pinch by inner and outer pipe tightly to obtain temporary transient fixingly, and the flexible rod majority of this class is used for stressed less subject matter, as Dust-removing mop, besom, beat on the handle that cleaning appliance such as brush and roller whitewash and use.

Also have a class can carry the greater weight flexible rod in addition, its structure is formed roughly same as described above, it all is inside and outside bar with mutual cover, just be provided with a brake mount at interior bar end, and the relative position of bar inwall is provided with the tooth position outside, the elasticity system catch clip that can supply brake mount to jump when making the flexible rod elongation, this structure can only be done unidirectional projection, when needs shorten, the pressure handle that then must utilize a peripheral hardware is located at clutch mechanism on the brake mount through connecting rod with pulling, system catch and tooth position are broken away from, commonly use in the daily life in sick bed limit feed table and the first-class purposes of cat ladder.The clutch mechanism of establishing in the pressure handle that has a peripheral hardware in design because of this class flexible rod affects, so constitutional detail is many, combination is complicated, the cost height, assemble time-consuming, and easy-maintaining not, and of a great variety, the product surplus, flooded market and be tending towards saturated, the better new product of developing is arranged in fact, can boost consumption, impel industry further to develop.

The purpose of this utility model is that a kind of flexible rod structure improvement will be provided, and makes it to have that the position is heightened in projection and clutch discharges the effect of withdrawal, and makes the flexible rod structure simplify to reach the purpose of making that assembly is few, cost is low, being easy to assemble maintenance.

Realize the utility model of above-mentioned purpose, mainly have an outer bar and an interior bar that adapted shape can socket-connect, wherein should be provided with tooth bar by outer bar inwall, and the front end and back end is provided with the edge that supports that directly contracts, and interior bar front end is provided with a brake mount, it is the short body of a tool pedestal, on the appropriate location of front end, offer prong with respect to outer bar tooth bar, interior pivot one elastic clamping body, its jig arm front end can be stretched outside the outstanding prong, this clamp front end is provided with to be nibbled spacingly to forming between the flank of tooth and tooth bar mutually, and is placed on above the brake mount at cover one clutch sleeve on the interior bar.

The concave tracks that wherein should outer bar both sides inwall be provided with relative projection puts tooth bar to provide respectively, interior bar diametric plane then is designed to the dumbbell shape that is that the tool waist dodges, be socketed in the outer bar with adaptive, the relative appropriate location of the ccontaining brake mount of interior again bar can be offered window and make the jig arm evagination, in addition at brake mount attached underneath one cup, its the place ahead is established prong and is made to form with jig arm and dodge, and the tube lateral plate is provided with slotted hole with on the set protruded stigma of bar wall front end in being fitted in.

Also have that the bar place is provided with a t shape big envelope in the bar front end socket outside, have beveled edge in this big envelope and put positioning ring for one, the back is closed multiple by an outer seal ring, and the bar below is provided with the shape of falling a t capping outside, and contracts to edge to constitute aforesaid footpath by means of two built-in t shape portions.

The utility model has the advantages that, make the effective shortening of the assembly of making flexible rod to reduce manufacture cost, simple in structure, be easy to the assembling maintenance, practical, in application, have projection and heighten position and the convenient advantage freely of clutch release withdrawal.

Below in conjunction with drawings and Examples, will be further described detailed construction of the present utility model, application principle, effect and effect.

Embodiment:

As Fig. 1, shown in 2, flexible rod structure improvement of the present utility model, mainly contain an outer bar 1 and an interior bar 2 that adapted shape can socket-connect, it is characterized in that, should be provided with tooth bar 11 by outer bar 1 inwall, and be provided with in the front end and back end that the footpath contracts support

edge

12,13, and interior bar 2 front ends are provided with a brake mount 3, it is the short body of a tool pedestal, offer prong 31 at front end on respect to outer bar tooth bar 11 appropriate locations, interior pivot one elastic clamping body 21, its jig arm 22 front ends can be stretched outside the outstanding prong 31, these clamp 21 front ends are provided with can form the flank of

tooth

23 and 11 of tooth bars to be nibbled spacingly mutually, and cover one clutch sleeve 4 is placed on the top of brake mount 3 on the interior bar 2.

In the specific implementation as shown in the figure, the both sides of bar 1 inwall can be provided with the concave tracks 14 of relative projection to supply to put tooth bar 11 respectively outside, interior bar 2 diametric planes then are designed to the dumbbell shape that is that the tool waist dodges, be socketed in the outer bar 1 to be fit to assembling, can offer window 25 on the relative appropriate location of interior again bar 2 ccontaining brake mounts 3 and make jig arm 22 evaginations, except that a clutch sleeve 4 is overlapped in brake mount 3 tops, in addition at brake mount 3 attached underneath one cup 7, cup 7 the place aheads are provided with prong 72 and make to form with jig arm 22 and dodge, the tube lateral plate be provided with slotted hole 71 be assemblied on the set protruded stigma 26 of bar 2 wall front ends;

When implementing assembling, bar 2 places can be provided with a t shape big envelope 5 in the outer bar 1 front end socket, have beveled edge 51 in this cover and put positioning ring 52 for one, the back is closed multiple by an outer seal ring 53, held stationary center when bar 2 stretches in making, bar 1 below then is provided with the shape of falling a t capping 6 outside, makes to borrow two built-in t shape portions to contract to

edge

12,13 to constitute aforesaid footpath when using.

As to reach projection when using and heighten the effect that position and clutch discharge withdrawal, its action as shown in Figure 3, when interior bar 2 tensions are upwards normally heightened, the jig arm 22 of its pivot elastic clamping body 21 can be yielded and comply and be regained and raise, outer naturally opening to nibble spacing mutually to the flank of tooth 23 and tooth bar 11 and to prevent downslide after determining the position.

When wanting to withdraw, as shown in Figure 4, in can making bar 2 again row improve, make sleeve 4 be subjected to the top to support that edge 12 is pushed and, make itself and tooth bar 11 break away from jig arm 22 claddings downwards, at this moment in bar 2 can not interruptedly withdraw flexibly.

When interior bar 2 is withdrawn into when bottom, show that as Fig. 5 the supporting that edge 13 in time arrives to cup 7 again of its below and sleeve 4 backed down sets back, jig arm 22 has at this moment broken away from the constraint of sleeve 4, and outer again opening with tooth bar 11 nibbled mutually, to treat the use of heightening of another time.

The foregoing description that need illustrate is the preferred construction combination, if the still change of doing according to design of the present utility model, the function of its generation does not exceed protection domain of the present utility model yet.
