Description

Mahjong machine table lifting mechanism

Technical field

The utility model belongs to mahjong machine technical field, is related to a kind of mahjong machine table lifting mechanism.

Background technique

With the rapid development of society, various amusement equipment are also developed rapidly, and mahjong machine is exactly one of which, It is scattered that washing for mahjong can be quickly completed.However, the elevating mechanism of mahjong machine in the prior art, the connection of supporter is compared Loosely, shakiness is supported in lifting process, causes entire elevating mechanism shaking amplitude big, and then influences the use of mahjong machine, and damage Bad mahjong machine.

Utility model content

The purpose of this utility model is to provide a kind of mahjong machine table lifting mechanisms, to overcome mahjong machine table top elevator The defect of the structure prior art.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

A kind of mahjong machine table lifting mechanism, including pedestal, be fixed on the base and hollow quiet column, be located at quiet column Interior dynamic column and the driving device that the dynamic column can be driven to carry out elevating movement in the quiet column, feature Be: the liner for being inserted into the inner wall of the top oral area is arranged in the top oral area of the quiet column, and the liner is stood with described move There is gap, the dynamic column bottom end outer wall, which has, is moving to what the pad position can be supported with the liner between column Protruding block.

By adopting the above technical scheme, moving has gap between column and liner, dynamic column can freely rise in the gap Drop, when dynamic column moves to extreme higher position, the protruding block at this moment moved on column can offset with liner, fill gap, so that Dynamic column can not shake, and finally to support mahjong table surface more stable.

Therefore, the mahjong machine table lifting mechanism of the utility model has the advantages that supporting bable tops are stable.

Specific embodiment

As shown in Figure 1 and Figure 2, the mahjong machine table lifting mechanism of the utility model, including pedestal 100, it is fixed on pedestal On 100 and hollow quiet column 300, the dynamic column 400 in quiet column and dynamic column 400 can be driven in quiet column The driving device of elevating movement is carried out in 300.

As shown in Figure 3, Figure 4, quiet column 300 and dynamic column 400 are square structure.At quiet 300 four angles in inside of column With inwardly protruded the first guide rail 301 extended along quiet strut length direction, moving has inwardly at 400 four angles in outside of column The recessed first sliding groove 401 with the cooperation of the first guide rail 301 extended along dynamic strut length direction.

The liner 501 of the inner wall of the top oral area setting insertion top oral area of quiet column 300, liner 501 and dynamic column 400 Between there is gap, the outer wall of dynamic 400 bottom position of column has and can support with liner when moving to 501 position of liner Protruding block 402.Specifically, the top mouth rim of quiet column 300, which is arranged, is fixed with lasso 500, which has insertion quiet Four pieces of liners 501 of 300 surrounding inner wall of column, the inner wall of quiet column 300, the other side are close in a side surface of the liner 501 The outer wall of surface and dynamic column 400 has gap, and the guide ramp originated with one section from lower edge.Protruding block 402 is Four, it is symmetrically located at the surrounding outer wall of dynamic column 400 two-by-two, is elongate in shape, edge passes through sloped transition to dynamic column 400 Outer wall on.

Driving device includes the motor 200 for being mounted on the base 100, and the screw rod 700 with motor drive is set in screw rod Nut block 800 on 700.

Specifically, there is cavity 101, quiet column 300 is fixed in cavity 101, and also solid in cavity 101 on pedestal 100 Surely there is the mounting rack 102 in quiet column 300.The mounting rack 102 is gantry structure, and motor 200 is fixed in cavity 101 simultaneously Positioned at the inside of mounting rack 102, screw rod 700 is located at the top of mounting rack, and the shaft of motor 200 passes through mounting rack 102 and screw rod 700 lower end connection.Two second guide rails 600 are fixed at the top of mounting rack 102, this two second guide rails 600 are symmetrically discrete The two sides above mounting rack 102, close to the two sides inner wall of quiet column 300.Two 600 upper ends of guide rail extend to quiet column 300 Top oral area, by across the connection of cover board 900 on two 600 tops of guide rail.The upper end of screw rod 700 is mounted on cover board 900 On.

800 two sides of nut block are respectively provided with guiding groove 801, and the guiding groove 801 and the second guide rail 600 cooperate, so that Nut block 800 can move up and down in quiet column 300 along the second guide rail 600.

Dynamic column 400 is set in the framework that two second guide rails 600 and cover board 900 are constituted, and moves the lower port of column 400 Portion is attached by bolts and nuts block 800.

Second guide rail 600 is channel steel structure, and inner hollow, inside is placed with circuit board.For the intelligence for realizing adjustable height Control, the circuit board are vertically intervally distributed with magnetic switch, and 600 surface of the second guide rail has the hole for allowing magnetic switch to expose, Guiding 801 surface of groove of nut block 800 has the magnet incuded by magnetic switch.In the present embodiment, there are three magnetic controls altogether Switch, is vertically distributed in the upper, middle and lower position of circuit board.Circuit board passes through the magnetic switch induced magnet of each position, So as to judge and control the adjustable height of dynamic column.

Therefore, the mahjong machine table lifting mechanism of the utility model has the advantages that lifting, supporting bable tops are stable.

In the present embodiment, dynamic 400 top of column also passes through shaft 1200 and connects returning face plate 1100.Pass through the returning face plate 1100 It is connect with mahjong table surface, may be implemented to fold mahjong table, to save placement space.

It is exactly above the utility model mahjong machine table lifting mechanism, using the above structure, has between dynamic column and liner There is gap, dynamic column can be freely lifted in the gap, when dynamic column moves to extreme higher position, at this moment be moved convex on column It is bittiness to offset with liner, gap is filled, so that dynamic column can not shake, finally to support mahjong table surface more steady It is fixed.

But those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate this Utility model, and being not used as the restriction to the utility model, if in the spirit of the utility model, to Variation, the modification of the upper embodiment will all be fallen in the claims of the utility model.
