Description

The antitheft connector of manhole cover and implements

The utility model relates to a kind of antitheft connector that is applicable to that manhole cover that industries such as plumbing, combustion gas, telecommunications, electric power are used and relevant implements are used.

At present, manhole cover is stolen very serious, and that causes thus falls the people, weighs down that thing and down-hole facility are stolen to have become the social concern that people generally are concerned about.Yet anti-theft devices such as its chain formula commonly used, screw-type, hidden-locked but exist unreasonable structure, anti-theft effect is poor, complex process, and shortcomings such as cost height, historical facts or anecdotes can not be satisfactory in using.

Shortcoming for the existing anti-theft device that overcomes implements such as manhole cover, special proposition is a kind of rational in infrastructure, technology is simple, cost is low, needs easy to operate, antitheft and that the connection effect is all good could be fixed and take off by special special equipment manhole cover and the antitheft connector of implements are to remedy present deficiency.

According to the utility model, a kind of manhole cover and implements with antitheft connector comprise be processed with at least one step through-hole above at least one coupling bar and one be connected thing and at least one high strong spring, one end of described coupling bar is processed with a bolt head, the other end is processed with at least one horizontal locking wings, described be connected also be processed with on the thing at least one in order to stop coupling bar and laterally locking wings around axle motion and latch recess that is positioned at step through-hole aperture one side of being locked, described high strong spring and coupling bar and laterally locking wings be connected thing and match.Describedly be connected the separate component that thing is processed with step through-hole and latch recess above can being; what be processed with step through-hole and latch recess above can also being is connected thing A spare; can also be top be processed with respectively step through-hole and latch recess by protective and be connected the assembly that thing is formed, even can be that two protectives that are processed with step through-hole and latch recess respectively will be connected thing and be clipped in wherein sandwich body.Coupling bar can have multiple section shape, and is wherein better circular; The horizontal locking wings of one end can be more than one, and can be multiple shape, can have on the bolt head of the other end one with should be antitheft the special-purpose supporting operating mechanism of consolidating on the taking equipment of being convenient to operate of dop of connector, this operating mechanism can be various ways such as interior hexagonal formula, cross slot type, outer-hexagonal formula, flat recess formula, coupling bar can be key and laterally locking wings be the separate component of one, the assembly that can also form with horizontal locking wings by key.Can be more than one with the high strong spring that coupling bar and step through-hole cooperate, and can be multiple shape.Latch recess can be more than one, preferably and the horizontal locking wings on the coupling bar supporting, and can be multiple shape.An also configurable metal cover or plastic closure on the macropore of step through-hole.Manhole cover and implements can be made as metal, macromolecular material etc. by multiple material with antitheft connector, can pass through kinds of processes, form as methods such as casting, die forging, machine, cold-heading, injection mouldings.

(be example) when using with manhole cover, the manhole cover contraposition that will prepare coupling bar and high strong spring earlier is placed on the manhole cover base, to support dop on the special-purpose solid taking equipment of the antitheft connector of this of location then sticks into and connects in the operating mechanism of fastening on the bolt head and put in place, last operation should special use be consolidated taking equipment, finish roof pressure and put in place → rotate predefined angle → return and unclamp entire exercise, promptly at first roof pressure bolt head makes horizontal locking wings on the coupling bar pass the latch recess end face high-strength length of spring compressed (general instrument and roof pressure power can not with this length of spring compressed) and puts in place, rotate predefined angle then, remove roof pressure power (return and unclamp) at last, the horizontal locking wings on the coupling bar promptly sticks in the latch recess that is connected thing by the bounce of high strong spring.At this moment, because the effect of high strong spring, latch recess has promptly been pinned horizontal locking wings, and coupling bar can not be rotated, and laterally an end of locking wings enters and blocked well lid seat ring bottom simultaneously, promptly locks and fixes.

When need will be the manhole cover of this antitheft connector of solid lock when taking off, still the operation sequence by fixedly the time is operated the solid taking equipment of this special use, promptly finish roof pressure put in place → rotate predefined angle → return and unclamp entire exercise, by the flange hole on the well lid well lid is opened and can be taken off then.

Because the special construction of this antitheft connector and to many-sided strict demands such as its material, hardness, intensity, and the extremely strong solid taking equipment of special use of the unique confidentiality of its structure is again the full-time keeping of special messenger, so it prevents that unlatching safety factor is high.

The utlity model has following major advantage: (1) applied range is fit to multiple implements such as manhole cover, drain cover and uses; (2) rational in infrastructure, theftproof performance is good, and is safe and reliable; (3) material is easy to get, and technology is simple, and cost is low; (4) but standardization can be exchanged general; (5) can simply transform implements such as existing manhole covers, supporting use, compliance is strong; (6) adopt special equipment to get admittedly, convenient and swift reliable.
