Abstract

The utility model relates to a safety warning sign, in particular to a safety sign capable of automatically rebounding to warn the cover absence of an inspection well. The safety sign comprises a warning board, an upright rod and a fixed frame, wherein a reflecting material is attached to the warning board. The safety sign is characterized in that the warning board is fixed at the upper end of the upright rod; the upright rod is movably connected with the fixed frame; a tension spring or a torsional spring is arranged between the upright rod and the fixed frame; and a rotating and limiting structure is arranged at the hinged part of the upright rod and the fixed frame. The safety sign is arranged on the inner wall of the inspection well, when a well lid is covered, the warning board is pressed below the well lid; and when the well lid is lost or moved away, the upright rod can be pulled by the spring to rotate upwards, so that the upright rod is erected and the warning board extends out of a well mouth. The utility model has the beneficial effects that the safety sign can rebound in time when the well lid is moved away to remind pedestrians and vehicles of noticing and avoid the safety accidents; and the safety sign has simple and practicable structure, is easy to process and manufacture and is applied to inspection wells above various underground pipelines of municipal sewage disposal, drainage, communication, power and the like.

Description

The safety sign that the inspection shaft uncovered can eject automatically

Technical field

The utility model relates to a kind of safety signs, relates in particular to a kind of safety signs of inspection shaft uncovered.

Background technology

A lot of blowdowns are arranged below urban road, draining, communication, underground pipelines such as electric power, on every pipeline along the line, many inspection shafts are arranged all, these all have the inspection shaft lid above inspection shaft, but when the inspection shaft lid damages, stolen or open after when in time not doing safety sign, these inspection shafts are just to forming major safety risks to pedestrian and vehicle, might fall down the pedestrian or cause the tragedy of car crash, such accident causes heavy losses to the people's lives and property, cause huge economic compensation loss also can for municipal sector and unit in charge of construction, and municipal sector is difficult in the damage of very first time discovery inspection shaft lid, lose or open after situation about in time not building, can't the very first time after potential safety hazard occurring do safety sign, cause the possibility of security incident very big, this also is to allow very stubborn problem of municipal sector.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of safety sign that can in time warn automatically when the inspection shaft uncovered.

In order to solve the problems of the technologies described above, the safety sign that the utility model provides a kind of inspection shaft uncovered to eject automatically, comprise warning sign, vertical rod and fixed mount, post reflectorized material or spraying reflectorised paint on the warning sign, it is characterized in that: warning sign is fixed on the vertical rod upper end, vertical rod is lived with fixed mount and is connected, tension spring or torque spring are installed between vertical rod and fixed mount, link place at vertical rod and fixed mount is provided with the rotary stopper structure, and the restriction vertical rod can only rotate to straight up position around fixed mount.

Further improvement of the utility model, described vertical rod are that two flat bar links form, and at least one flat bar therein is provided with the slotted hole that can regulate the vertical rod total length, is used to regulate the total length of vertical rod.

Further improvement of the utility model, described fixed mount is made up of a cross bar and a fixed head, described cross bar is formed by two flat bar links, and at least one flat bar therein is provided with the slotted hole that can regulate the cross bar total length, is used to adjust the total length of cross bar; Described fixed head is provided with installing hole, is used for fixed head is installed in the borehole wall.

The utility model is installed on the borehole wall of inspection shaft position near well head, when inspection shaft covers, warning sign and vertical rod all be crushed on well lid below, when well lid is lost or be opened, spring can spur vertical rod and rotate up, and vertical rod is holded up, and warning sign just stretches out well head, play the effect of prompting pedestrian and vehicle, prevent the generation of security incident.

The beneficial effects of the utility model are: at the inspection shaft losing of cover or when being opened, can eject the warning sign that has reflectorized material immediately automatically, in time remind pedestrian and vehicle to note avoiding inspection shaft, avoid the generation of security incident, reduce the have stable political situation economic loss of construction department of city; Carry out underground pipeline when safeguarding construction opening well lid, need not to establish in addition again safety signs, the work of transporting and reclaiming mark when reducing construction; The utility model is skillfully constructed, simple and practical, cost is low, is easy to processing and manufacturing, is applicable in the inspection shafts above the various underground pipelines such as municipal blowdown, draining, communication, electric power.

Fig. 3 is the lateral view after the utility model is depressed by well lid.

The specific embodiment

As Fig. 1～shown in Figure 3, the utility model comprises warning sign 1, vertical rod 3 and fixed mount, post reflectorized material 2 on warning sign 1 front and rear surfaces, warning sign 1 is fixed on vertical rod 3 upper ends, vertical rod 3 is lived by hinge 5 with the cross bar 6 on the fixed mount and is connected, mounting spring 4 between vertical rod 3 and the fixed mount, and hinge 5 places that are connected with fixed mount in vertical rod 3 are provided with the rotary stopper structure, be used to limit vertical rod 3 and can only rotate to straight up position around fixed mount under the tension of spring 4; Described vertical rod 3 is that two flat bars form by the bolt link, and at least one flat bar therein is provided with the slotted hole that can regulate vertical rod 3 total lengths; Described fixed mount is made up of cross bar 6 and fixed head 7, and described cross bar 6 is formed by the bolt link by two flat bars, and at least one flat bar therein is provided with the slotted hole that can regulate cross bar 6 total lengths; Cross bar 6 is welded on the fixed head 7, and fixed head 7 is provided with installing hole, is used for it is installed in the borehole wall of inspection shaft.

Spring 4 between above-mentioned vertical rod 3 and the cross bar 6 also can use torque spring to substitute, torque spring is enclosed within the rotating shaft of the hinge 5 that vertical rod 3 is connected with cross bar 6, one end of torque spring is pressed in the vertical rod 3, the other end is pressed on the cross bar 6, and its active force makes vertical rod 3 can rotate to position straight up when not being restricted.

During use, fixed head is installed on the borehole wall of inspection shaft position near well head, when inspection shaft covers, warning sign and vertical rod all be crushed on well lid below, state as shown in Figure 3; When well lid was lost or be opened, spring 4 can drive vertical rod 3 and rotate up, and vertical rod 3 is holded up, and warning sign 1 just stretches out well head, and state as shown in Figure 1 and Figure 2 plays the effect of prompting pedestrian and vehicle, prevents the generation of security incident.
