The utility model adopts the gravity restoring mechanism and utilizes the gravity center deviation effect of the seat board, the left and the right angle codes so that the seat board is automatically restored under the function of the gravity moment. The utility model has simple structure, convenient installation and good silencing effect; compared with a traditional spring restoring mechanism, the utility model is more reasonable and more scientific, and thus, has the advantages of low failure rate, long service life, etc.
Description
Technical field
The utility model relates to a kind of novel seat structure, particularly a kind of seat that has the gravity response agency.
Background technology
At present, this type of seat on the market adopts the spring response agency to realize the function that automatically replies of seat board mostly, as shown in Figure 1, its spring response agency comprises nylon ring 6 and buckles into its interior torsion spring 7 that this nylon ring 6 is set on the pivot pin 45 of gripper shoe 4, and utilization is bolted on the gripper shoe 4, angle sign indicating number 3 is set on the pivot pin 45 by axle sleeve 35, and bayonet lock 36 is buckled in the draw-in groove 61 of nylon ring 6, an end of above-mentioned torsion spring 7 is inserted in the draw-in groove 61, and the other end passes the aperture of angle sign indicating number 3.When seat board 1 was opened under external force, torsion spring 7 was in stress, in case the external force on the seat board 1 is eliminated, because the effect of torsion spring 7, seat board 1 will turn to the home position around pivot pin 45, thereby reaches the purpose of answer.
Above-mentioned spring response agency adopts the torsion of torsion spring to force seat board to be replied, and its defective is that when seat board was opened, torsion spring was in stress, and so long-term, torsion spring is easily because of fatigue failure; And when torsion discharged, the seat board rebound velocity was very fast, and noise is big, even be furnished with silencing means, effect is also not satisfactory; In addition, its structure is relatively complicated, and installation and maintenance work is also inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of seat that has the gravity response agency, and its gravity response agency spring response agency of tradition has characteristics such as simple in structure, easy for installation, good muffling effect.
The technical scheme that the utility model adopted: a kind of seat that has the gravity response agency, comprise seat board, backrest, a pair of foot rest with gripper shoe, and a pair of angle sign indicating number that is fixed in the seat board two bottom sides, it is characterized in that, one side of described gripper shoe is provided with pivot and stopping means, one side of described angle sign indicating number is provided with axis hole and protruding axle, and gripper shoe articulates by pivot, axis hole and angle sign indicating number.
Above-mentioned stopping means comprises upper dead flake and following stops, and protruding of this stopping means and angle sign indicating number cooperates, and can control seat board and pivot in the certain angle scope, and when protruding stop bit during in the upper dead flake place, seat board is in open mode; When protruding axle stop bit during in stops place down, seat board is in collapsed state.
In order to realize good erasure effect, be provided with rotary sleeve between above-mentioned pivot and the axis hole, be with the noise reduction cover on the protruding axle of two side angle sign indicating numbers, on the stops rubber blanket is housed under the supported on both sides plate.
The utility model adopts the gravity response agency, promptly utilizes the deviation of gravity center effect of seat board and left and right corner sign indicating number, and seat board is automatically replied under the effect of gravitational moment.It is simple in structure, and is easy for installation, and after installing silencing means such as rotary sleeve, rubber blanket, noise reduction cover additional, erasure effect is better., science more reasonable than traditional spring response agency, it is low to have fault rate, advantages such as long service life.
Description of drawings
Fig. 1 is for adopting the armchair structure schematic diagram of spring response agency;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is an assembly structure schematic diagram of the present utility model.
The specific embodiment
Shown in Fig. 2,3, the utility model is made up of seat board 1, backrest 5, a pair of foot rest 2 and a pair of angle sign indicating number 3 that is fixed in seat board 1 two bottom sides with gripper shoe 4, its gravity response agency is as follows: a side of gripper shoe 4 is provided with pivot 41 and stopping means, this stopping means comprises upper dead flake 42 and following stops 43, one straight flange of angle sign indicating number 3 is provided with axis hole 31 and protruding axle 32, above-mentioned gripper shoe 4 articulates with angle sign indicating number 3 by pivot 41, axis hole 31, angle sign indicating number 3 can be rotated around pivot 41, similarly, seat board 1 can rotate around pivot 41.The protruding axle 32 of above-mentioned stopping means and angle sign indicating number cooperates, can control seat board 1 certain angle (about 90 °) scope in around pivot 41 rotations, when protruding 32 stop bits during in upper dead flake 42 places of gripper shoe, seat board 1 is in the open mode of level; When protruding axle 32 stop bits during in following stops 43 places of gripper shoe, seat board 1 is in vertical collapsed state.In order to realize good erasure effect, be provided with between above-mentioned pivot 41 and the axis hole 31 on the protruding axle 32 of rotary sleeve 33, two side angle sign indicating numbers and be with noise reduction cover 34, rubber blanket 44 is housed on the stops 43 under the supported on both sides plate.
Each parts assemble sequence of the present utility model is as shown in Figure 3:
(1) rotary sleeve 33 is penetrated in the axis hole 31 of left and right angle sign indicating number 3;
(2) left and right angle sign indicating number 3 usefulness screws, nut are fastened on the seat board 1;
(3) seat board 1 is set on the pivot 41 of gripper shoe 4;
(4) buckling into rubber blanket 44 on the stops 43 down, sheathed noise reduction cover 34 plays sound deadening on the protruding axle 32 of left and right angle sign indicating number.
There is following relation between the above each part:
A. after seat board 1 is formed one with left and right angle sign indicating number 3, deviation of gravity center turning cylinder (being pivot 41), its center of gravity is at the postmedian of seat board 1, after leaning on than turning cylinder, thus the moment of rotating, seat board 1 can be around pivot 41 rotations.
B. because the position-limiting action of upper dead flake 42, following stops 43 has certain anglec of rotation (about 90 °) during seat board 1 rotation.
C. under external force, seat board 1 horizontal opening, in running order, the gravity arm of force lengthening of seat board 1, gravitational moment increases, in case the elimination of the external force on the seat board 1, under the effect of gravitational moment, seat board 1 will sway, and is returned to reset condition (as shown in Figure 2), thereby reaches the purpose of answer.
Seat described in the utility model can singlely use, and also can be used by a plurality of row's chairs of forming.
