Description

A kind of drum guide pipe

Technical field

This utility model relates to elevators field, is specifically related to a kind of elevator guide pipe.

Background technology

The layer door guide pipe Main Function of elevator is to make layer door have certain self-closing power, forces layer door to close, prevents layer door Arbitrarily opened and danger is occurred；Motion during layer door trip is then played guide effect by drum guide pipe.At present Layer door drum guide pipe mostly use metal material to make, there is good rigidity, be unlikely to deform；Shortcoming is that cost is higher, toughness Difference.And use the cost of PPC material relatively low, and there is non-corrosive, the advantages such as resistance to pressure easy to make is good, good toughness.

Utility model content

This utility model provide a kind of elevator drum guide pipe, solve guide pipe poor toughness, easily get rusty, cost High, be difficult to the problem installed, decrease cost price, improve service behaviour.In order to solve technique scheme, this utility model Adopt the following technical scheme that

A kind of drum guide pipe, including body, the four sides up and down of body is plane, the wider side of described body For bottom surface, the side relative with described bottom surface is upper bottom surface, and remaining both sides of described body are left surface and right flank, its Described in left surface equal with described right flank width and less than told upper bottom surface and described bottom surface, described bottom surface and described Described left surface and described right flank are wrapped in inside by upper bottom surface, and the both sides of described bottom surface and described upper bottom surface have part super Go out described left surface and described right flank, the rectangular cavity in inside of described body, bottom surface outer surface have equally distributed Shallow slot, between described shallow slot, spacing is 10mm-20mm.

A kind of drum guide pipe that this utility model provides, can be further arranged to described body cross section outline is work Font.

A kind of drum guide pipe that this utility model provides, can be further arranged to the used material of described body whole For hard PPC.

A kind of drum guide pipe that this utility model provides, can be further arranged to described body upper bottom surface and bottom surface Fillet has been led with the junction of side.

A kind of drum guide pipe that this utility model provides, can be further arranged to described bottom surface two ends has a court The projection rectangle rib of 2mm-10mm is had on.

A kind of drum guide pipe that this utility model provides, can be further arranged to upper bottom surface and the left and right of described body The wall thickness of side is equal, bottom surface relatively upper bottom surface and left and right side wall thickness thickness 1mm-5mm.

Advantage of the present utility model and having the beneficial effects that: to sum up, a kind of drum guide pipe that this utility model provides, adopt Having more fully performance for elevator when by drum structure, structure is more firm.Hard PPC is used to guide as drum The material of pipe, has the advantage such as non-corrosive, good toughness, and described fillet is so that guide pipe is more resistant to pressure, and toughness is more preferable.Bottom surface The rectangle rib being provided with has positioning function, the thicker bending coefficient that can effectively raise body of bottom surface wall thickness and usability Can, described shallow slot can play saving material on the premise of ensureing product quality, reduces the effect of cost.

Accompanying drawing explanation

Carry out preferred implementation of the present utility model below in conjunction with the accompanying drawings describing in detail or preferably, wherein,

Fig. 1 is the schematic cross-section of this utility model a kind of drum guide pipe.

Wherein: 1. body 2. bottom surface 3. upper bottom surface 4. left surface 5. right flank 6. rectangle rib 7. shallow slot 8. fillet.

Detailed description of the invention

The embodiment of reference accompanying drawing 1 drum a kind of to this utility model guide pipe is described further:

This utility model provides a kind of PPC pipe fitting guided for elevator door drum.Described body 1 is up and down Four sides is plane, and plane is readily produced processing, and the wider side of body 1 is bottom surface 2, relative with described bottom surface 2 Side is upper bottom surface 3, and remaining both sides of described body 1 are left surface 4 and right flank 5, wherein said left surface 4 and described right flank 5 width are equal and are less than described bottom surface 2 and described upper bottom surface 3, and described bottom surface 2 and described upper bottom surface 3 are by described left surface 4 Wrapping in inside with described right flank 5, there is part on the both sides of described bottom surface 2 and described upper bottom surface 3 beyond described left surface 4 He Described right flank 5, is so to be easy to out installation through hole beyond portion, and easily location and installation, the inside of described body 1 Rectangular cavity, has stability advantages of higher.Described bottom surface 2 outer surface is provided with equally distributed shallow slot 7, is uniformly distributed Shallow slot 7 can save material, it is easy to punching location.

Described body 1 cross section outline is drum, and its structure is easily installed, and practicality is wide.The material of described body 1 is hard Matter PPC, the guide pipe using hard PPC to make has good toughness, with low cost, it is easy to installs, is difficult to features such as getting rusty.

The junction of described left surface 4 and right flank 5 and described bottom surface 2 and described upper bottom surface 3 led fillet 6.Circle It is tough that the body 1 that angle 6 makes material be hard PPC makes body 1 have more by the bending of two sides when of being squeezed Property, it is hardly damaged, improves the resistance to pressure of body 1.

There is the rectangle rib 6 having a 2mm-10mm upward at described bottom surface 2 two ends, serve positioning action, make out peace The when of dress through hole, it is possible to make in the groove in the middle of the good described embedding rectangle rib 6 of screw and left and right side.Avoid screw convex Play the work of obstruction guide pipe.

The bottom surface 2 of described body 1 is thicker than upper bottom surface 3 and left surface 4 and right flank 5, the bottom surface wall thickness of body 1 The thicker counter-bending coefficient that improve body 1 and working strength, and in the case of this face needs to open installation through hole, its thickness The suitable intensity being screwed.

In sum, the drum guide pipe being made up of hard PPC is with low cost for elevator, has good toughness, easily Installing in producing, have good resistance to pressure, the design of drum structure, it is easy to location and installation simultaneously, stability is higher, practicality Wider.

Last it is noted that the foregoing is only preferred embodiment of the present utility model, it is not limited to this Utility model, although being described in detail this utility model with reference to previous embodiment, for those skilled in the art For, the technical scheme described in foregoing embodiments still can be modified by it, or to wherein portion of techniques feature Carry out equivalent, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all Within protection domain of the present utility model should be included in.
