Description
Technical field
The utility model relates to a kind of locomotive seat cushion engaging support mechanism, particularly relevant for a kind of difficult because of being subjected to the locomotive seat cushion engaging support mechanism that external impacts makes a mistake and operates.
Background technology
See also Figure 1A and Fig. 2 A, a kind of known locomotive seat cushion engaging support mechanism 1 mainly includes a mount pad 10, one first supporting bolt 21, one second supporting bolt 22, one first buckling element 30, one second buckling element 40, an elastic element 50, a seat cushion clasp 60 and two leads 70.
Shown in Figure 1B and Fig. 2 B, mount pad 10 is connected in a locomotive car body A.
Shown in Figure 1A, Figure 1B, Fig. 2 A and Fig. 2 B, the first supporting bolt 21 and the second supporting bolt 22 are connected to mount pad 10.
Shown in Figure 1B and Fig. 2 B, first buckling element 30 is sheathed on the first supporting bolt 21 in the mode of rotating, and first buckling element 30 has one first engagement section 31 and one second engagement section 32.
Second buckling element 40 is sheathed on the second supporting bolt 22 with rotating manner, and second buckling element 40 can rotate with respect to first buckling element 30.In addition, second buckling element 40 is first engagement section 31 or second engagement section 32 that optionally is sticked in first buckling element 30.
Shown in Figure 1A, Figure 1B, Fig. 2 A and Fig. 2 B, elastic element 50 is connected between first buckling element 30 and second buckling element 40, and elastic element 50 is positioned at the below of the first supporting bolt 21 and the second supporting bolt 22.

See also Fig. 3 A and Fig. 4 A, the locomotive seat cushion engaging support mechanism 100 of present embodiment mainly includes a mount pad 110, one first supporting bolt 121, one second supporting bolt 122, one first buckling element 130, one second buckling element 140, an elastic element 150, an extending element 155, a seat cushion clasp 160 and two leads 170.
Shown in Fig. 3 B and Fig. 4 B, mount pad 110 is connected in a locomotive car body A.
Shown in Fig. 3 A, Fig. 3 B, Fig. 4 A and Fig. 4 B, the first supporting bolt 121 and the second supporting bolt 122 are connected to mount pad 110.
Shown in Fig. 3 B and Fig. 4 B, first buckling element 130 is sheathed on the first supporting bolt 121 with rotating manner, and first buckling element 130 has one first engagement section 131 and one second engagement section 132.
Shown in Fig. 3 A, Fig. 3 B, Fig. 4 A and Fig. 4 B, elastic element 150 is connected between first buckling element 130 and second buckling element 140, and elastic element 150 is positioned at side under the first supporting bolt 121 and the second supporting bolt 122.
Extending element 155 is connected in second buckling element 140, and extending element 155 be positioned at second the supporting bolt 122 on (that is extending element 155 is the upper ends that are connected in second buckling element 140).At this, extending element 155 mainly is the weight that is used for increasing by second buckling element, 140 upper ends, in the hope of making the center-of-gravity position of second buckling element 140 can be positioned on the second supporting bolt 122.In addition, among present embodiment, the extending element 155 and second buckling element 140 are one-body molded.
Shown in Fig. 3 B and Fig. 4 B, seat cushion clasp 160 is connected in a locomotive seat cushion B, and seat cushion clasp 160 is fastened between first buckling element 130 and second buckling element 140 in separable mode.
Shown in Fig. 3 A, Fig. 3 B, Fig. 4 A and Fig. 4 B, two leads 170 are connected in second buckling element 140, and it can be used to order about second engagement section 132 that second buckling element 140 rotated and be located away from first buckling element 130.
Shown in Fig. 3 B, when second buckling element 140 is sticked in first engagement section 131 of first buckling element 130 (that is, when locomotive seat cushion B is not pressed on locomotive car body A as yet), seat cushion clasp 160 is to be located away from first buckling element 130 and second buckling element 140.
On the other hand, shown in Fig. 4 B, when second buckling element 140 is sticked in second engagement section 132 of first buckling element 130 (that is, when locomotive seat cushion B is pressed on locomotive car body A), seat cushion clasp 160 is to be fastened between first buckling element 130 and second buckling element 140.At this, by the fastening downforce of seat cushion clasp 160, first buckling element 130 can be pushed by seat cushion clasp 160, thereby can rotate around the first supporting bolt 121, is sticked in up to second buckling element 140 till second engagement section 132 of first buckling element 130.At this moment, elastic element 150 is to be in the state of being stretched, thereby can have a back stretch.
On the other hand, when two leads 170 are pulled and when ordering about second buckling element 140 and rotating, second buckling element 140 is understood first engagement section 131 that is sticked in first buckling element 130 by the back stretch that elastic element 150 provided, thereby make seat cushion clasp 160 be located away from first buckling element 130 and second buckling element 140, and then make locomotive seat cushion B start (shown in Fig. 3 B) from locomotive car body A.
As mentioned above, because the center-of-gravity position of second buckling element 140 has been positioned on the second supporting bolt 122, even so when whole locomotive seat cushion engaging support mechanism 100 was subjected to external impacts, the acceleration/accel or the force of inertia that are produced on second buckling element 140 can be very limited.In other words, can be at the force of inertia that is produced on second buckling element 140 much smaller than the friction drag between first buckling element 130 and second buckling element 140, thereby make second buckling element 140 be difficult for taking place the left-right rotation phenomenons.Therefore, when seat cushion clasp 160 is fastened between first buckling element 130 and second buckling element 140, second buckling element 140 can be difficult for rotating second engagement section 132 that is located away from first buckling element 130 because of external impacts, thereby make seat cushion clasp 160 can firmly be fastened between first buckling element 130 and second buckling element 140, and then make that the operational stability of locomotive seat cushion engaging support mechanism 100 is significantly promoted.
Though the utility model is exposed in preferred embodiment; right its is not in order to limit the utility model; anyly have the knack of this skill person; in the spirit and scope that do not break away from the utility model; when doing a little change and retouching, therefore protection domain of the present utility model is as the criterion when looking the claim scope person of defining who applies for a patent.
