Description

The fixed support that has plastic plate

The present invention relates to a kind of fixed support that is used to connect electric wiring, particularly cable line.

The support of this form uses the round-the-clock connection of element through being usually used in telecommunications and digital technology, and support bracket fastened framework is arranged on the outgoing cable line and fixes on the soleplate of said elements, connects cable by the input and output of support.

Its soleplate of fixed outdoor support that we are familiar with links to each other with base plate, both one designs, and base plate is placed on the ground usually.This base plate makes the fixed outdoor support have mechanical stability on the one hand, protects the cable of drawing from ground on the other hand.

In order to satisfy the ever-increasing requirement of information, need to install new or enlarge existing telecommunication and digital network.No matter what use in the telecommunication is cable technology or radiotechnics, these technology have a common fact, promptly electric component from regional group through-connection station or telecommunication center to the residential area or the isolated area more and more disperse.The applicant has applied for being provided with double framework on base plate in other application, by the similar common fixed outdoor support that be arranged in parallel, or the moulding rail of use hollow, form new supporting structure.These parts are metalworks, itself have enough intrinsic rigidities, and can any order surround framework, and perhaps moulding rail itself is the parts of the used framework of holding electrical element.

Problem be can not force users accept to set up increasing cable line, similar dispenser fixed support or be used for the fixed support of existing residential area radio station.Up to now, normally used outdoor fixed support seldom can satisfy this requirement.It is that to be used by the outdoor fixed support of the prior art of metal or plastic components assembling be not very convenient that a problem is arranged again.

The present invention proposes a kind of above-mentioned form fixed support easy to use, not only considers the operation of electric component as far as possible, and makes the user can assemble this support quickly and easily as far as possible.Another problem that the present invention proposes is to be the supporting bigger fixed support in residential area on every side.

Feature by claim 1 to 16 of the present invention can address the above problem.Improvement structure of the present invention is provided by dependent claims.

Basic design of the present invention is the plastic components weatherproof, can make different shape and color.In addition, plastic components weight is lighter, and it is 1m * 1m that a people can pick up area easily, and wall thickness is the working of plastics of 3mm.As basic point, this form fixed support that the present invention proposes is assembled by prefabricated respectively regenerated plastics plate with this, and plate makes up by positive lock, surrounds the stable framework of space structure.Said framework is used for fixing the electric component of cable line or station line and similar applications.

Desirable support comprises the fore-stock plate and the after-poppet plate of same type, and they form the side plate and the header field of said support indispensability simultaneously, and support is normally cuboidal.Be pushed forward into mutually by plate, lock mutually according to hook groove principle by forward and backward supporting plate side plate, two such plates can be sealed a metal framework, for example are arranged on the framework on the cable line soleplate.This set has been proved to be very effective in the bind mode and the structure on surface on leather trunk, compared with the support that the bight connects, this support has higher rigidity.

If desired, access slot or joint also can be designed to maze-type structure, to avoid the immersion of rainwater.If support may be subjected to the effect of high wind or mechanical load, connector can be designed to the device with latch or socket in addition, makes between the supporting plate more firm mutually.

Though the parts of two same types are easy to take apart each other, also available parts inequality replace two identical parts, are particularly providing under the very large support bracket fastened situation.In this case, can provide a plate earlier, for example the fore-stock plate has closed opening on it, seals up opening with door-plate then, has a plastic components on the door-plate, and this element can make it connect with the identical hinge pivot structure of door commonly used.Here also can use known lock or similar locking device.

For the middle part of framework, fore-stock plate and after-poppet plate can be provided with on the support element of additional structure equally pegs graft or guider.The guider of framework or retaining element should be connected with support element or plate internally, are impossible can only can the dismountings after opening door-plate from outside removal bracket like this.

The support of this form has the top cover of an isolated, and top cover is pressed on support or the plate, lives from the internal fixation of plate, can use screw or rivet if desired.The present invention can be covered in the connector of plate or forward and backward support by corresponding lug on the top cover owing to be provided with top cover.

The sealed plastic support of this cable line, if particularly its base plate and cable inlet seal with corresponding cable seal, for example the seal sealing made from rubber will produce a large amount of heat, can form corresponding cohesion water according to weather condition on the top cover of support.

For this reason, the present invention has designed an integral type fringing on top cover, or processes a tank on top cover, and Ning Ju water all can be fallen the electric component zone in addition that is provided with on framework and the framework so in all cases.On the other hand, the Rational structure of top cover also can avoid condensing the formation of water, leads to the outside opening that also plays the chimney effect such as one of processing on top cover.In case form cohesion water, the fringing water receiving of also available tank or similar sponge thing, water can pour off therefrom, can resemble and little by little dissipates the atmospheric water for condensing water.

For further reinforced boards, the present invention is processed as section bar in a side of sheet material.Be curved normally, or on concrete part, preferably at the outer setting press strip or the reinforcement of support with Element Design.This reinforced structure can be pressed into stratiform by the relevant design of support, and reasonably color is helpful to this.

The base plate of support preferably separates, and each base plate can be pushed to framework from both sides mutually, closes corresponding cable connector cover on the support base plate.The preferably glass fiber-reinforced polyester material of employed plastics, material are made stratiform or standard press part (sheet stock air blowing plastic film compound), if the suitable regrown material that uses.If the intrinsic rigidity of part is unsatisfactory, can use the injection moulding module of forming by improved polypropylene or polyethylene according to its size, however increased the weight of part.Added suitable ultra-violet stabilizer in the injection mould compound, this is that prior art is known.

For heat insulation, sound insulation, in order to reduce cohesion water, for fear of noise jamming, plate is lined with insulating part, and the most handy retaining element is fixed on the plate, makes the support of dispersion be convenient to repetitive process.Avoided being separated from each other of different plastics.The present invention also provides the mode of selectable door sealing or connector sealing.

In order to design light as far as possible plastic stent, also use the stable rigid frame of forming by metal foil sheet frame or similar material, and be provided with distortion release beam in the above, the cable of introducing is suspended on these beams by corresponding clamp or hanging element.Load does not act on the trestle component, but acts on the framework, so trestle component can design quite gently.

For smaller support, the plate of framework then is designed to integral type, or the enhanced type plate, for example strengthen in the bight, or distortion is set discharges beam.

The outdoor support of cable line can resemble and be arranged on the soleplate at present common, be installed on this soleplate by the stable framework of the space structure of metal manufacturing, manufacturer only provides trestle component, that is: the base plate that separates, back plate, header board, door-plate and top cover, if necessary, also can provide seal, assemble outdoor support according to field-installed method then.
