Abstract

The utility model discloses a noise reduction elevator cage bottom, which comprises a base frame. The base frame is connected with at least three rib plates, a face plate is arranged above rib plates, rib plates are positioned on the base frame in criss-cross mode, and rib plates are arranged in a shape of a chess board. The noise reduction elevator cage bottom utilizes a plurality of rib plates in a chess-board-shaped structure, a gap is reversed between the periphery of the face plate of the elevator and a protrusion of the base frame, and nonmetal materials are filled in the gap, thereby reducing noise effects brought by a drum face effect and improving comfortableness of the elevator.

Description

At the bottom of the noise reduction elevator sedan-chair

Technical field

The utility model relates to a kind of elevator, relates in particular to a kind of car bottom of elevator.

Background technology

Along with the increase of development of city and population pressure, floor is increasingly high, and elevator has become instrument indispensable in the urban life.People when taking elevator, to elevator take that environment is whether comfortable relatively to be paid attention to, and the size of noise is to estimate an important indicator of elevator level of comfort.

The car bottom of existing elevator is as depicted in figs. 1 and 2, comprises that underframe, underframe are connected with a small amount of horizontal or vertical floor 2, welding panel 3 on the floor 2, and panel 3 is generally iron plate.

Because number of ribs is less, general sedan-chair bottom framework is " day " word or " order " font structure, and the iron plate of top welding covers on the sedan-chair bottom framework fully.Adopt this kind structure, import into by the sedan-chair bottom framework or occupant's hard heel when knocking on panel, form " drum face " effect easily, bring very big noise to be stranded and scratch as vibrations.

The utility model content

The technical matters that the utility model will solve provides at the bottom of a kind of noise reduction elevator sedan-chair, can effectively solve " drum face " effect of elevator panel, the noise at the bottom of the reduction elevator sedan-chair.

In order to solve the problems of the technologies described above, the utility model provides at the bottom of a kind of noise reduction elevator sedan-chair, comprises underframe, is connected with floor on the underframe, and there is panel the floor top, and said floor has 3 at least, and is crisscross on underframe, is the tessellate setting.

Further, said chassis perimeter raises up, and the middle part forms sunk area, and said floor is located in the sunk area.

Further, said panel around apart from the gap that is raised with of chassis perimeter.

Further, fill with non-metallic material in said gap.

Further, said non-metallic material is a rubber.

Further, said panel is a non-metallic material.

Further, between the said floor weighting material is arranged.

Further, said panel is a non-metallic material.

The utility model adopts most floors to be the structure of tessellate, and is provided with the gap between elevator panel periphery and the underframe convexity, fills non-metallic material in the gap, has reduced the noise effect that " drum face " effect is brought, and has improved the traveling comfort of elevator.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further so that those skilled in the art can better understand the utility model and implementing, but the embodiment that lifts not conduct to the qualification of the utility model.

In order to solve the problems of the technologies described above, the utility model provides at the bottom of a kind of noise reduction elevator sedan-chair, comprises underframe 1, some (at least 3) floor 2 and panel 3.The periphery of said underframe 1 raises up, and the middle part forms sunk area, and floor 2 is located in the sunk area, and floor 2 is crisscross, is tessellate and is arranged on the underframe 1, and there is panel 3 floor 2 tops; The utility model has reduced " drum face " size in " drum face " effect owing to adopted more floor 2, and the extent of vibration that produces noise is reduced, and can effectively reduce noise.

As optimal way, should make panel 3 around apart from underframe 1 periphery be raised with gap 4, preferably gap 4 usefulness non-metallic materials are filled, preferably adopt rubber to fill; Gap 4 makes panel 3 and underframe 1 be difficult to form confined space, adopts rubber or other non-metallic material to fill, and can absorb the vibration of panel 3, reduction noise that can be further.Especially, panel 3 also can adopt non-metallic material, and between floor 2, also weighting material can be arranged; The noise of non-metallic material is generally less than metallic material, and the effect of amplifying can be played in the space between the floor 2, adopts this kind structure more can further reduce noise.

The above embodiment is the preferred embodiment that proves absolutely that the utility model is lifted, and the protection domain of the utility model is not limited thereto.Being equal to that the technical personnel in present technique field is done on the utility model basis substitutes or conversion, all within the protection domain of the utility model.The protection domain of the utility model is as the criterion with claims.
