Abstract

The invention discloses a tea table for a locomotive. The tea table for the locomotive comprises a tea table main body mounted on a locomotive compartment body. The tea table for the locomotive further comprises a mounting seat and a limiting block, wherein the limiting block is fixed on the mounting seat; the side edge of the tea table main body is provided with a limiting shaft; the limiting block is provided with a circular arc limiting part; a track groove is formed in the mounting seat corresponding to the circular arc limiting part; the limiting shaft is inserted in the track groove; the limiting shaft is extruded on the circular arc limiting part; and when the tea table main body is turned over downwards to a horizontal position from a vertical position, the limiting shaft moves within the track groove. According to the invention, as the limiting shaft is in interference fit with the circular arc limiting part, the tea table main body has a limiting effect at each angle in the process of turning over the tea table main body between the vertical position and the horizontal position so that the tea table main body is prevented from being rapidly unfolded in the turnover process; therefore, the tea table main body can stop at any angle during turning over for 90 DEG.

Description

Locomotive tea table

Technical field

The present invention relates to a kind of locomotive tea table, belong to passenger car internal unit technical field.

Background technology

At present, often install in the compartment of motor train unit train or ordinary train and use tea table, existing tea table does not have damping function, and after tea table is released, opening speed is very fast, and movement range is large, makes troubles, even injure passenger by a crashing object to passenger.

Summary of the invention

Technical matters to be solved by this invention is: overcome the deficiencies in the prior art, provides a kind of locomotive tea table, its flexible overturning, and can be spacing in switching process.

In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of locomotive tea table, comprise the tea table body be arranged on locomotive envelope, it also comprises mount pad and limiting stopper, limiting stopper is fixed on mount pad, the side of described tea table body is provided with limit shaft, limiting stopper has circular arc limiting component, mount pad has rail groove with circular arc limiting component corresponding position, limit shaft is inserted in rail groove, and limit shaft is squeezed on circular arc limiting component, when tea table body turn to level attitude downwards from vertical position, limit shaft moves in rail groove.

Further in order to realize 90 ° of upsets of tea table body, the described central angle corresponding to circular arc type circular arc limiting component is 90 °.

Further in order to all can well fix at vertical and level two end positions, the both sides of described tea table body are equipped with limit shaft, described limiting stopper is also provided with two, be respectively left limit block and right limit block, the bottom of the circular arc limiting component on described left limit block is provided with locking notch, the top of the circular arc limiting component on described right limit block is also provided with locking notch, limit shaft and lock groove mouth interference fit.

Further, the upper surface of described tea table body is made up of PC plastic flagstone.

Further, the coated soft roll structure of lower surface of described tea table body, the surface of soft roll structure is fireproof facing material.

After have employed technique scheme, limit shaft of the present invention extrudes with circular arc limiting component and coordinates, tea table body each angle in the switching process of vertical position and level attitude is made to play position-limiting action, to prevent in switching process that tea table body is too fast to be opened, tea table body all can be stopped the arbitrarily angled of upset 90 °; Locking notch of the present invention, makes tea table body all have mechanical position limitation at vertical position and these two extreme position of level attitude, and being conducive to increases tea table body at the reliability of collapsed state with using state, and it is more firm to fix; Flexible operation of the present invention, effectively utilizes turn over function, and increasing while structure more can conserve space, increases ride quality.

Detailed description of the invention

In order to make content of the present invention more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation.

As shown in Fig. 1 ~ 5, a kind of locomotive tea table, comprise the tea table body 1 be arranged on locomotive envelope, it also comprises mount pad 2 and limiting stopper, limiting stopper is fixed on mount pad 2, the side of tea table body 1 is provided with limit shaft 4, limiting stopper has circular arc limiting component 5, mount pad 2 has rail groove 2-1 with circular arc limiting component 5 corresponding position, limit shaft 4 is inserted in rail groove 2-1, and limit shaft 4 is squeezed on circular arc limiting component 5, when tea table body 1 turn to level attitude downwards from vertical position, limit shaft 4 is mobile in rail groove 5.

Central angle corresponding to circular arc type circular arc limiting component 5 is 90 °, to realize freely overturning of vertical position and level attitude.

The both sides of tea table body 1 are equipped with limit shaft 4, be respectively left limit axle and right limit axle, limiting stopper is also provided with two, be respectively left limit block 3-1 and right limit block 3-2, the bottom of the circular arc limiting component 5 on left limit block 3-1 is provided with locking notch 6, the top of the circular arc limiting component 5 on right limit block 3-2 is also provided with locking notch 6, limit shaft 4 and locking notch 6 interference fit.

Left limit block 3-1 and right limit block 3-2 all adopts high strength, high tenacity, resistance to abrasion, environmental-protection fireproof material to make.

The upper surface of tea table body 1 adopts the high resistance to fireproofing plastic board of PC, and through water transfer printing special process, color and texture reach similar plank effect, thus replace plank, i.e. expendable weight but also realize art designing's effect.

The coated soft roll structure of lower surface of tea table body 1, the surface of soft roll structure is high abrasion, fireproof facing material.

The inner skeleton of tea table body 1 is that the automobile structural steel (SPH440T=2.0) of high strength completes through the operation such as mould molding, welding, thus makes tea table reach high strength (75Kg concentrated load can be born in front end), lightweight (≤10Kg).

Principle of work of the present invention is as follows:

Limit shaft 4 and circular arc limiting component 5 interference fit on limiting stopper, extrude limiting stopper by limit shaft 4 and produce friction, make tea table body 1 can in arbitrarily angled stop, can be locked in locking notch 6 when tea table body 1 moves to vertical state, otherwise, when tea table body 1 moves to horizontality, also can be locked in locking notch 6.

Limit shaft 4 of the present invention and circular arc limiting component 5 interference fit, tea table body 1 each angle in the switching process of vertical position and level attitude is made to play position-limiting action, to prevent in switching process that tea table body 1 is too fast to be opened, tea table body 1 all can be stopped the arbitrarily angled of upset 90 °; Locking notch 6 of the present invention, makes tea table body 1 all have mechanical position limitation at vertical position and these two extreme position of level attitude, and being conducive to increases tea table body 1 at the reliability of collapsed state with using state, and it is more firm to fix; Flexible operation of the present invention, effectively utilizes turn over function, and increasing while structure more can conserve space, increases ride quality.

Above-described specific embodiment; technical matters, technical scheme and beneficial effect that the present invention solves are further described; be understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
