Technical field
The utility model relates to the mahjong table lifting platform, and particularly a kind of mahjong table lifting platform advances the noise-reducing structure of board inlet.
Background technology
Existing mahjong table lifting platform structure as shown in Figure 1, its mainly comprise be positioned at the bottom scrape board seat 1 ', scrape board flap 2 ', telescopic fall way 3 ' and be arranged on the fall way top mould holder 4 ' form, fall way 3 ' outside in the above structure, scrape board seat 1 ' on noise-reducing structure is not set, with the desktop mah-jong pieces along advance board inlet push in barrel process of shuffling can with scrape board flap 2 ', scrape board seat 1 ', fall way 3 ', directly touch, its result not only produces a large amount of noises, also can produce adverse influence to surrounding enviroment simultaneously.
The utility model content
At the problems referred to above, the utility model has designed the noise-reducing structure that a kind of mahjong table lifting platform advances board inlet, and it is guaranteeing to have realized the noise reduction purpose under the retractile prerequisite of fall way, have simple in structure, noise is low, the characteristics of long service life.
For achieving the above object, the utility model is by the following technical solutions:
A kind of mahjong table lifting platform advances the noise-reducing structure of board inlet, comprises mainly and scrape board seat, fall way and mould holder that it is characterized in that: described fall way arranged outside of scraping on the board seat has can guarantee the retractile noise-reducing structure of fall way.
Above-mentioned noise-reducing structure is the bellows that the elastomeric flexible material of a usefulness is made, and it directly is nested with and is arranged on the fall way outside.
Above-mentioned bellows top is connected in moulds in the holder, the bottom with scrape the board seat and directly offset.
Above-mentioned bellows top is connected in moulds in the holder, and the bottom is arranged on the connecting hole of scraping board seat center by silencer cover location.
Above-mentioned silencer cover is up-small and down-big truncated cone-shaped structure, and its foot diameter is greater than scraping board seat connecting hole diameter, and silencer cover inside is provided with a through hole that is used for the spacer dimple pipe, and the outside of through hole is equipped with the connecting hole of scraping on the board seat.
The truncated cone-shaped lateral surface of above-mentioned silencer cover is provided with patch.
Above-mentioned silencer cover lateral surface top is provided with flange, and the junction of flange and inner via hole is provided with and is with shock absorbing ring.
The utility model is directly at the arranged outside bellows of fall way, simultaneously silencer cover is set as noise-reducing structure scraping on the board seat, fundamentally stopped the desktop mah-jong pieces are pushed in barrel process of shuffling and scrape the board seat, scrape touching of board flap, fall way along advancing board inlet, overcome the defective that existing mahjong table structure exists, have simple in structure, noise is low, the characteristics of long service life.
At this, because of bellows is made by elastomeric flexible material, it is compressed synchronous shortening at downward each ripple of the effect of moulding holder when fall way descends, it resets when fall way rises and fall way extends synchronously, thereby is guaranteeing that under the retractile prerequisite of fall way mah-jong pieces being bumped less than fall way has realized the noise reduction purpose.
At this, the locate mode of the utility model bellows has two kinds, wherein a kind of is that the bellows top is connected in and moulds in the holder, the bottom with scrape the board seat and directly offset, another kind of locate mode is that the bellows bottom is arranged on the connecting hole of scraping board seat center by silencer cover location, in this mounting means, removed and scraped board flap structure.
More than be up-small and down-big truncated cone-shaped structure, its foot diameter is greater than scraping board seat connecting hole diameter, and its middle part indent is provided with bellows bottom positioning through hole, and the outside of through hole is equipped with the connecting hole of scraping on the board seat.At this, the truncated cone-shaped lateral surface of silencer cover is provided with patch, and the flange that silencer cover lateral surface top is provided with and the junction of interior bone are provided with shock absorbing ring.The structure of above silencer cover is provided with on the one hand and has guaranteed that bellows is not shifted in telescopic process, simultaneously mah-jong pieces has been played further silencing and damping effect.
Description of drawings
The stereochemical structure decomposing schematic representation of Fig. 1, existing mahjong table lifting platform;
The stereochemical structure decomposing schematic representation of Fig. 2, mahjong table lifting platform of the present utility model;
The stereochemical structure decomposing schematic representation of Fig. 3, second kind of embodiment of the utility model;
The combining structure sectional view of Fig. 4, second kind of embodiment of the utility model.
The specific embodiment
As shown in Figure 2, a kind of noise-reducing structure of mahjong table lifting platform comprises mainly and scrapes board seat 1, fall way 2 and mould holder 3 that described fall way 2 arranged outside have can guarantee its retractile noise-reducing structure.
Noise-reducing structure is the bellows 4 that the elastomeric flexible material of a usefulness is made, and it directly is nested with in fall way 2 outsides.In the present embodiment, the top of bellows 43 is connected with moulding holder, the bottom of bellows 4 with scrape board seat 1 and directly offset.
Shown in Fig. 3 and 4, be second kind of embodiment of the present utility model, the difference of itself and first kind of embodiment is, the bottom of bellows 4 by silencer cover 6 with scrape board seat 1 and be connected.
Silencer cover 6 is up-small and down-big truncated cone-shaped structure, and its foot diameter is greater than scraping board seat connecting hole 11 diameters, and silencer cover 6 inside are provided with a through hole 61 that is used for the spacer dimple pipe, and the outside of through hole 61 is equipped with the connecting hole of scraping on the board seat 11.The truncated cone-shaped lateral surface of silencer cover 6 is provided with patch 8.Silencer cover 6 lateral surface tops are provided with flange 63, and flange 63 is with shock absorbing ring 7 with the junction setting of interior bone 61.
Silencer cover 6 is the truncated cone-shaped structure, and its middle part indent is provided with bellows 4 bottom locating holes 61, and the outside of locating hole 61 is equipped with the connecting hole of scraping on the board seat 1 11.The truncated cone-shaped lateral surface 62 of silencer cover 6 is provided with shock absorbing ring 7 with the junction of indent through hole 61.The truncated cone-shaped lateral surface 62 of silencer cover is provided with patch 8.The structure of above silencer cover is provided with on the one hand and has guaranteed that bellows 4 is not shifted in telescopic process, simultaneously mah-jong pieces has been played further silencing and damping effect.
The bellows 4 structure settings of above-mentioned two kinds of embodiments, the touching of mah-jong pieces and fall way 2 when fundamentally having stopped to shuffle overcome existing mahjong table structure and had the big defective of noise, have simple in structure, noise is low, the characteristics of long service life.
Bellows 4 of the present utility model is made by elastomeric flexible material, it is compressed synchronous shortening at downward each ripple of effect of moulding holder 3 when fall way 4 descends, it resets when fall way 2 rises and fall way 2 extends synchronously, thereby is guaranteeing to have realized the noise reduction purpose under the fall way 2 retractile prerequisites.
