Description

Anti-stealing device mounted on sink well cover or grating

It belongs to plumbing equipment manufacture technology field in the urban public utilities.

From being used for the antitheft of manhole cover and grate plate and the measure of protecting, do not see prior art at present.

Install can be antitheft manhole cover and grate plate, mainly be to solve on the present urban pavement manhole cover and grate plate just to be seated on the framework that reaches grate plate on the cloudy walling crib just being opened easily or stolen problem of generation therefrom simply.

Be installed in the anti-theft device on manhole cover (5) and the grate plate (26), its feature mainly is by rolling disc (16), rolling disc locator card (12), and expansion link (14), U-shaped circle (15) and open and close device that can this device of folding are formed.Centre bore on the rolling disc (10) has square hole, three kinds in cross bore and hole, garden, they respectively with open and close device (Fig. 6), (Fig. 7) He (Figure 14) be used, the rolling disc locator card is fixed on lid (5) and the plate (26) with securing member, its effect is that rolling disc is limited in activity in the cover, expansion link and rolling disc couple together by axle (13): U-shaped circle (15) is fixed on above the cover plate, it can control only side-to-side movement in its circle of expansion link, when using this anti-theft device, centre bore (10) lining on the rolling disc is inserted by the centre bore on manhole cover or the grate plate in the open and close device end, turn open and close device then, this moment, open and close device drove turn disc, rolling disc draws expansion link again and moves, at this moment an end of expansion link just can insert cinclides (19), (24) or be attached on the bottom surface of crib inner ring (4), in order to guarantee that manhole cover is unlikely to rotate about when the closure state.On crib inner ring (4), designed groove (18), designed projection (17), and made its concavo-convex cooperation in manhole cover edge.

Be installed in the anti-theft device on the manhole cover, can there be " people " font (Fig. 2) and two kinds of methods of " one " font (Fig. 3) to select, the anti-theft device that is installed on the grate plate can have (Fig. 9), (Figure 10) and (Figure 11) three kinds of methods are selected, the component of anti-theft device can be according to the difference of its stressing conditions, use metal respectively, plastics, glass fiber reinforced plastic and other chemical synthetic material etc. are made, anticorrosion from stressing, rolling disc and the most handy plastics of locator card and glass-reinforced plastic material, expansion link also can use the glass fiber reinforced plastic material to make, if expansion link is a metallic object, be preferably in its appearance and put thin plastic flexible pipe, if what the anti-theft device critical piece used is steel-product, can be with zinc-plated, brush oil, methods such as brush anticorrosive paint are carried out preservative treatment, by above-mentioned explanation, this device is installed on manhole cover and the grate plate as can be seen, it is in design, all fairly simple in technology and the making, be can be for those skilled in the art grasped and realized.

The advantage of anti-theft device may be summarized to be 3 points: 1. dependable performance, and this device provides multiple efficient ways to select in design, in case closed, there is not special tool just can't open.2. economy, this principle of device is simple, and cost increases few, is convenient to promote the use of.3. social benefit is good, and its use not only can solve loses the heavy losses that manhole cover and grate plate cause to country in a large number, the unexpected injury that the masses that also avoided simultaneously passing by on one's way cause therefrom.

Drawing explanation: be installed in the anti-theft device on manhole cover and the grate plate, mainly be that rolling disc (16) is arranged, rolling disc locator card (12), expansion link (14), U-shaped circle (15), axle (13) securing member (11) constitutes, this device is installed on the back side of manhole cover or grate plate, the unlatching of manhole cover and grate plate is with closed, is that the end with open and close device inserts in the rolling disc centre bore (10), carries out then that turn realizes.(Fig. 1) be the overall assembling drawing of cloudy cover for manhole, on this figure and A--A and the B--B section as can be seen, its structure mainly is divided into three parts: first part master is cloudy walling crib framework, second largest part is the manhole cover body, the third-largest part is the anti-theft device that is installed on the manhole cover back side, first part mainly is by walling crib (1), walling crib bottom surface (2), reinforcing rib (3), inner ring (4) is formed, inner ring is used for supporting well lid (5), second largest part mainly is by well lid, garden shape stiffener (6), bar shaped reinforcing rib (7), leg (8), perforate (9), centre bore (10), and the hole that is used to install rolling disc locator card and U-shaped circle is formed, garden shape stiffener and bar shaped reinforcing rib are used to strengthen the load-bearing capacity that is subjected to of lid, perforate is used to uncap, centre bore is used for the open and close device of hole insertion from then on, leg can play the effect of protection anti-theft device, the third-largest part mainly is by rolling disc (16) rolling disc locator card (12), the securing member of fixation clamp (11), rolling disc centre bore (10) axle (13), expansion link (14), U-shaped circle and this circle securing member (15) are formed, in addition, in the design of the junction of lid and walling crib projection (17) is arranged, groove (18) carries out concavo-convex cooperation, be installed in the apparatus structure that can carry out two kinds of selections on the well lid back side as can be seen from (Fig. 2) with (Fig. 3), (Fig. 2) be " people " font structure, (Fig. 3) be " one " font structure, (Fig. 4) considered on the walling crib wall, can establish a hole (19), this hole can match with the expansion link end, (Fig. 5), be three kinds of multi-form rolling discs (Figure 13) and (Figure 16), rolling disc is connected with the mode of expansion link with axle, there is hole, garden (38) to connect and is connected two kinds of methods with arcuate socket (29), (Fig. 5) rolling disc is " ten " font centre bore, it and (Fig. 7) the supporting use of " ten " prefix open and close device, (Figure 13) rolling disc is square centre bore, it and (Fig. 6) the supporting use of square toes open and close device, (Figure 16) rolling disc is a garden shape centre bore, respectively there is a hole (39) its both sides, it and (Figure 14) the supporting use of open and close device; Open and close device (Figure 14) is the interlock form, for example use (Figure 14) open and close device, earlier with the activity template (37) of open and close device from centre bore be inserted into rolling disc below, go up carrying handle hand (31) then, handle drives chain link (34), carry 90 ° on about the chain rotating ring divides the activity template of both sides, dop (40) and hole (39) are matched, and turn handle (29) can be realized the rotation of rolling disc then, (Fig. 8) be the overall fitting figure of grate plate and framework, as can be seen, its structure mainly is divided into three parts: first is a framework, mainly by frame (23) on this figure and the D--D section, hole (24), eaves (25) is formed; Second portion is a grate plate, mainly by plate body (26), and mating holes (10), reinforcing rib (27), water falling hole (28) and the required hole of installation anti-theft device securing member are formed; The third-largest part is the anti-theft device that is attached on the grate plate back side, this device is basic identical with its principle of device that is installed on the manhole cover back side, open and close device has (Fig. 6), (Fig. 7), (Figure 14) three kinds, cooperate the square centre bore of rolling disc respectively, " ten " font centre bore and garden shape centre bore, be that one group of device (Figure 10) respectively is installed in the grate plate both sides is that one group of device is installed in the middle part (Fig. 9), (Figure 11) from grate plate more firmly, designed four expansion links.
