Description

A kind of elevator buffer device

Technical field

The utility model relates to a kind of shock absorber, particularly a kind of elevator buffer device for playing buffering effect during used during elevator falling.

Background technology

Elevator is divided into two large classes substantially, staircase and companion ladder, companion ladder is mainly used in megastore, Business Building, residential building, and because the used during elevator falling accident that companion ladder is long neglected and in disrepair or other reasons causes also has a lot, now commercially for the shock absorber of elevator cushion, substantially be all adopt cushion rubber or spring to carry out a buffer action, but strike on cushion rubber or spring with the impulsive force of elevator high-speed falling, elevator all can be bounced because of elasticity reason, easily secondary injury is caused to the passenger in elevator, so need a kind of elevator buffer device just can address these problems.

Utility model content

For existing technical deficiency, the utility model provides a kind of elevator buffer device.

In order to achieve the above object, technical solution adopted in the utility model is: a kind of elevator buffer device, comprise plate and lower plate, upper plate lower surface is fixed with at least four strut bars, it is protruding that described strut bar is provided with the equal annular arrangement of some spacing, and the protruding upper end of annular arrangement is greater than lower end; Described lower plate is provided with the through hole of corresponding strut bar, and described strut bar inserts in through hole, and strut bar is also provided with springing, and described lower plate bottom surface is provided with the gripping mechanism for controlling strut bar one-way movement.

Described springing is spring assembly, and described spring assembly is at least made up of one group of spring.

Described spring assembly comprises the first spring, the second spring and the 3rd spring, and when state of nature, the first spring, the second spring and the 3rd spring are arranged on strut bar successively from high to low.

Described gripping mechanism is arranged in the groove of lower plate bottom surface, groove both sides are also provided with step surface, gripping mechanism comprises two corresponding active fastening blocks, is provided with extension spring between two described active fastening blocks, and two described step surfaces are provided with detouchable block.

Under two described active fastening block correspondences, the position of plate through hole is provided with the otch for blocking strut bar, and otch is arc-shaped inclined-plane, and accordingly, the end of strut bar is conical.

Spacing between annular arrangement projection on described strut bar is greater than the thickness of active fastening block.

Described upper plate and lower plate are equipped with the maintenance through hole for convenient for maintaining, and upper plate is corresponding with the maintenance lead to the hole site of lower plate.

Described upper plate upper surface is provided with one deck rubber pad, and the position of rubber pad correspondence maintenance through hole is also provided with through hole.

The beneficial effects of the utility model: this product is for the problem striking meeting resilience on shock absorber during used during elevator falling, striking shock absorber when have developed a kind of used during elevator falling can not the device of resilience, during impact attenuation device resilience, the passenger in elevator is caused to the problem of secondary injury when solving used during elevator falling, and this product structure is simple, installing/dismounting, maintenance all very convenient, safety is high.

Detailed description of the invention

As shown in Figure 1 to 4, a kind of elevator buffer device, comprise plate 1 and lower plate 2, upper plate 1 lower surface is fixed with at least four strut bars 3, described strut bar 3 is provided with the equal annular arrangement projection 4 of some spacing, and protruding 4 upper ends of annular arrangement are greater than lower end; Described lower plate 2 is provided with the through hole of corresponding strut bar, and described strut bar 3 inserts in through hole, and strut bar 3 is also provided with springing, and described lower plate 2 bottom surface is provided with the gripping mechanism for controlling strut bar one-way movement.

Described spring assembly comprises the first spring 5, second spring 6 and the 3rd spring 7, when state of nature, first spring 5, second spring 6 and the 3rd spring 7 are arranged on strut bar 3 successively from high to low, the object arranging three springs is to play an effect progressively cushioned, also can arranging more springs.

Described gripping mechanism is arranged in the groove of lower plate 2 bottom surface, groove both sides are also provided with step surface 8, gripping mechanism comprises two corresponding active fastening blocks 9, is provided with extension spring 10 between two described active fastening blocks 9, and two described step surfaces are provided with detouchable block 11.

The position of the described lower plate through hole of two active fastening block 9 correspondences is provided with the otch for blocking strut bar 3, and otch is arc-shaped inclined-plane, and accordingly, strut bar 3 end is conical; Otch is convenient to strut bar can not change position through active fastening block.

Spacing between annular arrangement projection 4 on described strut bar 3 is greater than the thickness of active fastening block 9, because the thickness being at least greater than active fastening block just can play the effect of a clamping.

Described upper plate 1 and lower plate 2 are equipped with the maintenance through hole 12 for convenient for maintaining, and upper plate 1 is corresponding with maintenance through hole 12 position of lower plate 2.

Described upper plate 1 upper surface is provided with one deck rubber pad 13, and the position of rubber pad 13 correspondence maintenance through hole 12 is also provided with through hole, and a preliminary buffering effect is played in the effect of rubber pad, makes can not produce huge impact noise during shock.

When striking upper plate when used during elevator falling, the rubber pad of upper plate plays a tentatively buffering and decrease the injury that noise causes people's ear, as the pressure increases, upper plate is due to pressure drop, first spring, second spring and the 3rd spring progressively increase the effect playing and progressively cushion along with pressure, one end downslide active fastening block that pillar stiffener inserts lower plate is stuck between the gap of pillar stiffener two annular arrangement projections, serve the effect preventing recoil of spring, inserted in the maintenance through hole of upper plate and lower plate by a screw rod, by lower plate or on the screw rod of plate fixed by movable nut, play a support effect, then the block of lower intraplate gripping mechanism is unloaded, then active fastening block is taken out, then slowly rotation activity nut, slowly rise strut bar.
