Abstract

The utility model relates to a road board fixing frame used for fixing road surface markers such as advertisement boards and light boxes on the telegraph poles and fixing objects. The utility model can automatically adjust the angle and reposition along the wind direction. The utility model mainly consists of a fixing bracket, which is characterized in that a turn-plate is rotatably arranged on the fixing bracket; the turn-plate is fixed with the road board through a middle shaft; and a spiral spring is sleeved on the middle shaft. When in use, the road board rotates along the wind direction and keeps corresponding with the wind direction so as to lighten the influence of the wind force to the road board; when the wind stops, the road board can automatically reposition. The utility model has the effects of novel and simple structure, and convenient mounting, therefore realizing automatic adjusting, automatic repositioning, flexible adjusting and rapid repositioning.

Description

The guideboard fixed mount

Technical field: the utility model belongs to hang uses device, particularly a kind of special fixing device that is used for fixing outside guideboard such as billboard, lamp box etc.

Background technology: along with development of urbanization, on the road surface or street branch has showed various billboards, lamp box etc., and content relates to enterprise, products propaganda, public welfare advertisement etc.But present guideboard all is that employing is fixed basically, promptly directly be packed on electric pole or the fixture, and for the power of arousing attention, the guideboard major part all is laterally on the street.Because the street is as an air channel, when blowing, the wind-force on the street can be very big, especially for the guideboard on the electric pole, usually can be scraped tiltedly by wind, and people often see that the maintenance personal is at the whole guideboard of wind descendant wage adjustment.Not only waste a lot of human and material resources, and all certain influence can be arranged to the fastness and the life-span of guideboard.

Summary of the invention: but the purpose of this utility model is to provide a kind of box haul to adjust automatically reset special-purpose guideboard fixed mount behind angle, the wind automatically.

The utility model is achieved in that

The guideboard fixed mount, mainly form by fixed support, it is characterized in that: a rotating disk is equipped with in activity on fixed support, this rotating disk is solidly installed by intermediate shaft and guideboard, on intermediate shaft, also be set with a volute spring, this helical spring end and support is solidly installed, the other end is by a push pedal one-way check that is packed on the rotating disk.

After the utility model adopted above structure, about guideboard or up and down two sides installed guideboard respectively, and when guideboard was subjected to windage, guideboard drove intermediate shaft and rotates along support, thereby made guideboard and wind direction maintenance always, alleviated the positive influences of wind-force to guideboard.When guideboard rotated, volute spring was stressed, and after becalming, under helical spring reset response, guideboard can automatically reset.Have novel structure, simple, effect easy for installation has realized automatic adjustment, has automatically reset, and adjusts flexibly, resets rapidly.The friction adjusting gear that is provided with on the rotating disk can be adjusted the initial wind-force that guideboard begins to rotate effectively simultaneously, has guaranteed the relatively stable of guideboard.

Description of drawings:

Fig. 1 is a kind of structural representation of the present utility model;

Fig. 2 is the side view of Fig. 1;

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

In the accompanying drawing, 1 is that guideboard, 2 is that support, 3 is that rotating disk, 4 is that intermediate shaft, 5 is that volute spring, 6 is that pin, 7 is that push pedal, 8 is that tension spring, 9 is a turn trough.

Embodiment: as shown in drawings, the utility model guideboard fixed mount is a kind of fixedly pavement marker such as guideboard such as billboard, lamp box erecting frame that is exclusively used in.Mainly be made up of support 2, this support 2 is packed on electric pole or the fixture by screw.A rotating disk 3 that has intermediate shaft 4 is equipped with in activity on support 2, and intermediate shaft 4 and rotating disk 3 are solidly installed; Intermediate shaft 4 one ends pass support 2 and are solidly installed volute spring 5 of other end suit with guideboard 1.On rotating disk 3, also have i.e. 180 ° the turn trough 9 of a semicircle along the circumference of rotating disk 3.Also be fixed with a pin 6 on support 2, this pin 6 passes above-mentioned turn trough 9 and is connected with an end of volute spring 5.On rotating disk 3, the opposite of turn trough 9 also is provided with a push pedal 7, this push pedal 7 contacts with the other end of above-mentioned volute spring 5, be used for unidirectional promotion volute spring 5, and when rotating disk 3 counter-rotation, 7 pairs of volute springs 5 of push pedal is inoperative.Under the normal condition, push pedal 7 contacts with volute spring 5 but is inoperative, and above-mentioned pin 6 is positioned at the centre position of turn trough 9 simultaneously.

Side at rotating disk 3 also is provided with a friction adjusting gear, and this device is positioned on the above-mentioned support 2.This friction adjusting gear is a tension spring 8, and can roll by runner or ball between this tension spring 8 and the rotating disk 3 link to each other.Also be provided with the groove of an arc on the excircle of rotating disk 3, above-mentioned runner or ball are positioned at groove.Adjust the tensioner of tension spring 8, can adjust the friction between runner or ball and the rotating disk 3 effectively.Accurate position when simultaneously groove can guarantee effectively that rotating disk 3 resets.

Above-mentioned semicircular turn trough 9, and the pin 6 that is positioned at turn trough 9 centre positions can guarantee that guideboard 1 makes 90 ° of maximum left-right rotation.

During installation, two sides mounting bracket 2 respectively about guideboard 1 or up and down, one of them volute spring 5 for dextrorotation, another is the derotation installation.Again support 2 is packed on electric pole or the fixture and gets final product.For guaranteeing the rotating effect of guideboard 1, above-mentioned support 2 is positioned at 1/3rd places of guideboard 1.This moment, the push pedal 7 of two sides contacted with volute spring 5 but inoperative, and pin 6 is positioned at the centre position of turn trough 9 simultaneously.Adjust tension spring 8, thereby adjust the force of compression of 8 pairs of rotating disks 3 of tension spring, under general wind-force, rotating disk 3 can not rotate under the effect of tension spring 8, thereby guarantees the relatively stable of guideboard 1.When wind-force was big, guideboard 1 stressed box haul rotated, and the intermediate shaft 4 and the rotating disk 3 on phase limit rotate thereby drive with it.When rotating disk 3 rotated, the push pedal 7 on it will promote volute spring 5, makes volute spring 5 tighten, work, and the wind-force that is subjected to up to guideboard 1 reaches balance with the elastic force of volute spring 5, and this moment, guideboard 1 and wind direction basically identical were subjected to windage less.And this moment, the support 2 of opposite side, owing to oppositely install, push pedal 7 is done away from volute spring 5 motions, and is inoperative to volute spring 5.After wind-force reduced or disappears, above-mentioned balance was broken, and volute spring 5 discharges elastic force, thereby oppositely promotes push pedal 7, thereby drives rotating disk 3 and intermediate shaft 4 backward rotation, resets up to guideboard 1.When oppositely the wind comes from, the support 2 of opposite side will play a part same, thereby guarantees that also guideboard 1 box haul rotates.
