Abstract
The utility model relates to a kind of telescopic mosquito net support vertical rod, it is characterized in that comprising upper support bar, lower support bar and contractile ring structure; The bottom of wherein said upper support bar is plugged in the upper end of lower support bar, and described contractile ring structure to be set on upper support bar and can to move up and down and fixing, and the external diameter of contractile ring structure is greater than the internal diameter of lower support bar.Its advantage is: what upper support bar can be very stable is axially positioned on lower support bar, and upper support bar there will not be downslide problem, and bearing capacity is good, easy to adjust.
Description
Technical field
The utility model relates to a kind of telescopic mosquito net support vertical rod.
Background technology
Existing telescopic mosquito net support vertical rod comprises upper support bar and lower support bar, and the lower end of described upper support bar is plugged on the upper end of lower support bar, and the junction of upper support bar and lower support bar is located by dialling pearl; Dialling pearl can not well be axially positioned on lower support bar by upper support bar, and the power of bearing when the upper end of upper support bar is comparatively large, and upper support bar can slide down.
Summary of the invention
The purpose of this utility model be overcome the deficiencies in the prior art and provide that a kind of upper support bar can be very stable be axially positioned on lower support bar, upper support bar there will not be the telescopic mosquito net support vertical rod of the one of downslide problem.
In order to achieve the above object, the utility model is achieved in that it is a kind of telescopic mosquito net support vertical rod, it is characterized in that comprising upper support bar, lower support bar and contractile ring structure; The bottom of wherein said upper support bar is plugged in the upper end of lower support bar, and described contractile ring structure to be set on upper support bar and can to move up and down and fixing, and the external diameter of contractile ring structure is greater than the internal diameter of lower support bar.
Card code, clamping screw and locking nut is comprised in described contractile ring structure, described card code is set on upper support bar, external diameter after card code tightens up is greater than the internal diameter of lower support bar, described clamping screw is through the opening two ends of card code, and described locking nut is located at the end of clamping screw thus the openings of sizes of adjustment card code.
The utility model advantage is compared with prior art: what upper support bar can be very stable is axially positioned on lower support bar, and upper support bar there will not be downslide problem, and bearing capacity is good, easy to adjust.

Fig. 2 is the utility model embodiment one stereogram;
Fig. 3 is the structural representation that the utility model implements two;
Fig. 4 is the utility model embodiment two stereogram.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.It should be noted that at this, the explanation for these embodiments understands the utility model for helping, but does not form restriction of the present utility model.In addition, if below in described each embodiment of the utility model involved technical characteristic do not form conflict each other and just can be combined with each other.
In the utility model describes, term " on " and the orientation of the instruction such as D score or position relationship be based on orientation shown in the drawings or position relationship, it is only the utility model instead of require that the utility model with specific azimuth configuration and operation, therefore can not must be interpreted as restriction of the present utility model for convenience of description.
Embodiment one
As shown in Figures 1 and 2, it is a kind of telescopic mosquito net support vertical rod, comprises upper support bar 1, lower support bar 3 and contractile ring structure; The bottom of wherein said upper support bar 1 is plugged in the upper end of lower support bar 2, and described contractile ring structure to be set on upper support bar 1 and can to move up and down and fixing, and the external diameter of contractile ring structure is greater than the internal diameter of lower support bar 3.In the present embodiment, the section of upper support bar 1 and lower support bar 3 is all rounded.
During use, as length of the present utility model need be regulated, loosen contractile ring structure, contractile ring structure can being moved up and down on upper support bar 1, upwards twitching or move down upper support bar 1, when reaching desired height, contractile ring structure is tightened and is fastened on upper support bar 1, pin footpath due to contractile ring structure is greater than the internal diameter of lower support bar 3, and therefore upper support bar 1 can be longitudinal positioning of on lower support bar 3, and the utility model has regulated.
In the present embodiment, card code 2, clamping screw 4 and locking nut 5 is comprised in described contractile ring structure, described card code 2 is set on upper support bar 1, external diameter after card code 2 tightens up is greater than the internal diameter of lower support bar 3, described clamping screw 4 is located at the opening two ends of card code 2, and described locking nut 5 is located at the end of clamping screw 4 thus the openings of sizes of adjustment card code 2.During use, the position of adjusting lock nut 5 on clamping screw 4, makes the openings get smaller of card code 2, and card code 2 can be made like this to be fastened on upper support bar 1, because the external diameter after card code 2 tightens up is greater than the internal diameter of lower support bar 3, therefore card code 2 can support on lower support bar 3; When the longitudinal length of upper support bar 1 need be adjusted, the position of adjusting lock nut 5 on clamping screw 4, the opening of card code 2 is made to become large, this scale code 2 is removable at upper support bar 1, now can vertically move upper support bar 1, when adjusting to desired position, making again the openings get smaller of card code 2 and being fixed on upper support bar 1, namely completing adjustment.
Embodiment two
As shown in Figures 3 and 4, its technical scheme is substantially identical with the technical scheme of embodiment one, and difference is upper support bar 1 and lower support bar 2 is square tube, and the section of card code 2 is square.
Below by reference to the accompanying drawings detailed description is made to embodiment of the present utility model, but the utility model is not limited to described embodiment.For the ordinary skill in the art, carry out multiple change, amendment, replacement and distortion when not departing from principle of the present utility model and aim to these embodiments still to fall within protection domain of the present utility model.
