Specific embodiment
Below with reference to each attached drawing, the utility model is described in detail.
It please refers to shown in Fig. 1-4, the utility model provides the positioning device on a kind of column, for solid with the cooperation of column 1
Due to any position of column 1,1 side of column is equipped with limit rack gear 2.The umbrella stem of parasols is identical as 1 structure of column, therefore,
The positioning device can be used on parasols positioning inclined umbrella cover, so that umbrella cover is fixed on any position in umbrella stem.
The positioning device includes: shell 3, limited block 4 and handle 5.The shell 3 is for being sheathed on the column 1
Outside, it and can be moved along the length direction of column 1.Limited block 4 along close to or far from limit rack gear 2 direction movably
It is installed in shell 3.One end of the limited block 4 towards the limit rack gear 2 is equipped with fixed tooth 40, the fixed tooth 40 and institute
Limit 2 face contact of rack gear occlusion is stated with the fixation limited block 4.One end of handle 5 is rotatably installed on the shell 3,
The other end of hand 5 connects the limited block 4 to drive the limited block 4 mobile.The number of teeth of the fixed tooth 40 is two or more,
It ensure that enough support strengths, so that the umbrella cover being installed in the positioning device is able to maintain stabilization.
In the present embodiment, limited block 4 can be driven mobile by the rotation of handle 5, so that limited block 4 is close to or far from limit
Rack gear 2, when limited block 4 is close to rack gear, when fixed tooth 40 is engaged with limit 2 face contact of rack gear, limited block 4 is fixed on column 1
A certain position, that is, positioning device is fixed on a certain position on column 1；When limited block 4 is far from rack gear, fixed tooth 40
It is separated with limit rack gear 2, then positioning device can be moved along column 1, so as to adjust the position of positioning device.The positioning is filled
It sets and is applied in parasols, umbrella cover is connect with the positioning device, and the position of umbrella cover is adjusted by positioning device.Due to positioning device
Fixation tooth 40 and limit rack gear 2 between be engaged by face contact, and the number of teeth of fixed tooth 40 is more than two, such knot
Structure stress point is distributed in rack gear, and ensure that enough support strengths, can be firmly installed umbrella cover, when umbrella cover is by wind
When, it is not easy to damage the structure.
It please refers to shown in Fig. 1, the shell 3 may include first shell 31 and second shell 32, first shell 31 and
Two shells 32 match to form shell structure, and further, the first shell 31 and the second shell 32 are screwed
Together.
The positioning device further includes dynamic clamping head and quiet clamping head 6, connects the shell 3 and the limited block 4 so that the limit
Position block 4 has the trend mobile towards the limit rack gear 2.When initial position, as shown in figure 3, fixed tooth 40 and limit 2 phase of rack gear
Mutually occlusion, squeeze grip 5, the rotation of handle 5 drive fixed tooth 40 far from limiting tooth, and dynamic clamping head and quiet clamping head 6 is compressed at this time, such as Fig. 4
It is shown, the position of positioning device is adjusted, hand is unclamped, due to the effect of dynamic clamping head and quiet clamping head 6, so that limited block 4 is moved towards limit rack gear 2
Dynamic, fixed tooth 40 is engaged with limit rack gear 2 again, as shown in figure 3, to fix the positioning device.Dynamic clamping head and quiet clamping head 6 is arranged can
To realize automatically reseting for limited block 4, positioning device can be retightened by unclamping handle 5, using upper more convenient.
Further, the dynamic clamping head and quiet clamping head 6 is pressure spring, and the both ends of the pressure spring are respectively held against limited block 4 and shell 3, and
So that limited block 4 has the trend mobile close to limit rack gear 2, so that being engaged between fixed tooth 40 and limit rack gear 2 stronger.
It please refers to shown in Fig. 2,4 two sides of limited block are equipped with guiding projection 41, the corresponding guiding projection of the shell 3
41 are equipped with guide groove 31, and the guiding projection 41 is inserted into the guide groove 31 and is slidably matched with the guide groove 31.So set
Meter, is conducive to the moving direction for limiting the limited block 4, and when so that limited block 4 is close to limit rack gear 2, fixed tooth 40 can be right
Quasi- limit rack gear 2, it is easier to adjust the fixation position of positioning device.
The positioning device further includes idler wheel 7, and idler wheel 7 is rotatably mounted in the shell 3, is rolled with the column 1
Cooperation, is conveniently adjusted installation site of the positioning device on column 1.In one embodiment, the quantity of idler wheel 7 is four, is uniformly divided
It is distributed in the surrounding of column 1, but not limited to this.
One end of the handle 5 is equipped with rotating boss 51, is rotatably installed on the shell by the rotating boss 51
3.51 structure of rotating boss is very simple, can not only fix one end of handle 5, but also the rotation of handle 5 may be implemented, installation
It is very convenient.
In one embodiment, the other end of the handle 5 is equipped with columnar projections 52, and the limited block 4 is equipped with limiting groove 42,
The columnar projections 52 are inserted into the limiting groove 42 to connect the limited block 4.The example structure is simple, is easy dress
Match, it is only necessary to the columnar projections 52 on handle 5 are inserted into the limiting groove 42 of limited block 4, it is very convenient.But it is not limited to
This, in other embodiments, the other end of the handle 5 can be connect by pin or rivet with the limited block 4, same non-
It is often convenient and practical.
Further, the fixed tooth 40 is square shaped teeth, and the tooth form of the rack gear and the tooth form for fixing tooth 40 are adapted.Side
The contact area of shape tooth is big, and stress point is not concentrated in certain point, so that positioning device can be firmly secured on column 1
A certain position.
The number of teeth of the fixed tooth 40 is more, then fix tooth 40 and limit rack gear 2 between be engaged it is more secured that is, fixed
Position device is fixed on more firm on column 1, and the ability to bear of the umbrella cover for being installed in positioning device is stronger.Preferably, institute
The number of teeth for stating fixed tooth 40 is three, but not limited to this, it is also possible to two or four or five etc., the utility model pair
This is with no restriction.
It please refers to shown in Fig. 1-4, the utility model also provides a kind of 1 component of column, is used for and any of the above-described embodiment institute
The positioning device stated cooperates with the fixation positioning device, which includes column 1 and limit rack gear 2, the limiting tooth
Item 2 is set to 1 side of column, and the limit rack gear 2 is engaged with the limited block 4 is fixed on positioning device on column 1
Any position.The tooth form of the limit rack gear 2 and the tooth form of the fixed tooth 40 are adapted.
The above is only the preferred embodiment of the present invention, not thereby limits the patent protection of the utility model
Range, it is all with equivalent structure transformation made by the utility model specification and accompanying drawing content, directly or indirectly it is used in it
His relevant technical field similarly includes within the protection scope of the present utility model.
