Abstract
The utility model discloses a metal lighting electric pole antitheft access cover. The utility model adopts a method that an access cover is integrated with an access hole instead of the method that the prior metal lighting electric pole access cover and the access hole are separated and are fixed only by an upper screw and a lower screw, a connecting rod, a spring, a lining board are arranged in the access cover, the traction of the connecting rod pulls the access cover and the retraction of the spring, and pushes an end cap of the connecting rod to drive the access cover, the central hole of the lining board is used to allow the connecting rod to steadily and freely pass through; both ends of the lining board are welded in the grooves of the electric pole access hole to ensure the access cover and the access hole are connected into a whole.
Description
Affiliated technical field
The utility model relates to the processing of metal electric pole, in order to prevent the stolen of metal illumination electric pole access cover.
Background technology
Present known metal illumination electric pole access cover fastening mainly takes up and down two screws, chain of triangulation and hexagon socket head cap screws to be fixed, and steals because of being easy to general purpose tool such as bottle opener, wrench it is unloaded; Stolen because of access cover, electric wire and street lamp protective device in the electric pole manhole all are exposed outside, and influence very much the city appearance of the city, and also to constitute for people's safety dangerous because of live wire simultaneously.
Summary of the invention:
In order to overcome the fixing easily stolen present situation of existing metal illumination electric pole access cover coping screw; The utility model provides a kind of (the antitheft access cover of metal illumination electric pole), this antitheft access cover is taked to be different from existing access cover and is separated the method that only depends on screw fixing with manhole, and the method that adopts access cover and manhole to be connected as a single entity can prevent the stolen of metal illumination electric pole access cover so effectively.
The utility model solves its technical problem, and the technical scheme that is adopted is: increase by one one end at the access cover inwall and burn-on the circular reinforcing bar (diameter is at the 6-10 millimeter, and length is the 7-10 centimetre) of plug as connecting rod; A spring (diameter of bore pierces into connecting rod and is advisable, and length is a 4-5 centimetre) block length square plate centre drill eye is to pierce into the connecting rod thick 2-3 millimeter of being advisable, long 10 centimeters, wide 2-3 centimetre) as liner plate.Respectively saw a groove in middle and upper part, metal electric pole manhole both sides; in order to welding liner plate two ends; above connecting rod; spring; liner plate and manhole groove size require and should decide according to metal electric pole interior diameter and manhole height; earlier connecting rod not being had plug one end pierces into spring (plug is blocked spring; spring is not skidded off) pass the liner plate central eye again; (liner plate central eye diameter is less than spring diameter) makes spring clip in the middle of connecting rod plug and liner plate; and push hard the connecting rod plug a little; spring is gently compressed; connecting rod one end of liner plate central eye will be passed; be welded on center, access cover inwall middle and upper part; to lean on spring one side plate two ends to be welded in the metal electric pole manhole groove at last; access cover and metal electric pole manhole are linked as in one; owing to adopted the traction pulling access cover of connecting rod; the flexible promotion connecting rod of spring drives access cover; the central eye of liner plate is stablized connecting rod and is walked freely; the two ends of liner plate are fixed on the interaction on the electric pole manhole; access cover and manhole are connected as a single entity, thereby reach the stolen purpose of protection access cover.
The effect that the utility model is useful is: because of metal electric pole access cover and connecting rod liner plate, spring, manhole are connected as a single entity, prevents the stolen of metal electric pole access cover, played protective effect for the city appearance of the city, and simple in structure.
Description of drawings
Fig. 1 is the utility model constructional drawing
Fig. 2 is a metal electric pole schematic diagram
Among Fig. 1: 1 connecting rod, 2 springs, 3 liner plates, 4 access covers
Among Fig. 2: 1 manhole 2, groove
The specific embodiment
No plug one end of connecting rod (1) pierces into spring (2) in figure (1), pierces into liner plate (3) central eye again, and enforces the plug of connecting rod (1) a little; Make the light compression of spring (2), will pass connecting rod one end of liner plate (3) central eye again, the center on being welded in access cover (4) inwall; Connecting rod (1), spring (2), liner plate (3), access cover (4) are connected with each other, to be welded on figure (2) manhole at last near the liner plate two ends of spring one side in the groove (2) of (1) both sides, middle and upper part, be connected as a single entity thereby form access cover and electric pole manhole, therefore can prevent the stolen of metal illumination electric pole access cover.
In the time of in the maintenance metal electric pole, access cover (4) outwards need only be pulled out the 2-3 centimetre, be welded on the plug back-moving spring (2) of access cover (2) inwall connecting rod (1), make spring (2) compression, and rotation access cover (4) exposes manhole, and the spring of loosing one's grip is upheld promotion connecting rod (1) plug, tiltedly be fixed on access cover (4) on the manhole, after maintenance finishes, be pulled outwardly access cover (4), make bullet build (2) compression, and rotation access cover (4) resets, and loose one's grip spring (2) is upheld, promote connecting rod (1) plug tension access cover (4), cover manhole.Owing to adopt the traction pulling access cover (4) of connecting rod (1), flexible promotion connecting rod (1) plug of spring (2) drives access cover (4), the central eye of liner plate (3) is stablized connecting rod (1) and is walked freely that the two ends of liner plate (3) are fixed on the electric pole manhole, and access cover (4) and manhole are connected as a single entity.
Claims (3)
1, one (the antitheft access cover of metal illumination electric pole), increase by one one end at the access cover inwall and burn-on the circular reinforcing bar of plug as connecting rod, the rectangle steel plate of a centre drill eye is as liner plate, a spring, it is characterized in that: connecting rod does not have plug one end, puts on spring, is piercing into the liner plate central eye, to lean on the liner plate two ends of spring one side to be welded in metal electric pole both sides, manhole middle and upper part and the groove, and form access cover and manhole and be connected as a single entity because of connecting rod, liner plate and spring action.
2, require described according to right 1: (the antitheft access cover of metal illumination electric pole) is characterized in that: the traction pulling access cover of connecting rod, and the flexible promotion connecting rod plug of spring drives access cover, and the central eye of liner plate is stablized connecting rod and is connected freely; The two ends of liner plate are fixed in the groove of metal electric pole manhole both sides.
3, according to right 1, require described: (the antitheft access cover of metal illumination electric pole) is characterized in that: the plug of connecting rod does not skid off spring greater than spring, and the central eye of liner plate should make spring clip between plug and liner plate less than spring.
