See fig. 1-6.
A seat comprises two brackets 1 and a seat plate; the two brackets 1 are connected through a front fixing plate 2 and a rear fixing plate 3; the front fixing plate 2 is positioned at the front side of the two brackets 1 and is respectively connected with the two brackets 1 through first bolts 4; the rear fixing plate 3 is positioned at the rear side of the two brackets 1 and is respectively connected with the two brackets 1 through second bolts 5; the seat plate comprises a bottom plate 6 and a backup plate 7 connected to the rear side of the bottom plate 6; a first sliding seat 8 connected to the front fixing plate 2 in a sliding manner is connected below the bottom plate 6; the rear side of the backup plate 7 is connected with a second sliding seat 9 which is connected to the rear fixing plate 3 in a sliding manner; the first sliding seat 8 is connected to the front fixing plate 2, and the second sliding seat 9 is fixed on the rear fixing plate 3; after the front fixing plate 2 and the rear fixing plate 3 are respectively connected with the two brackets 1, the seat plate is limited between the two brackets 1.
Specifically, the left side surface of the seat plate abuts against the support frame 1 on the left side of the seat plate, and the right side surface of the seat plate abuts against the support frame 1 on the right side of the seat plate.
Specifically, an upper abutting surface 11 is arranged above the front fixing plate 2; the upper abutment surface 11 abuts against the lower wall of the bottom plate 6.
Specifically, a front abutting surface 12 is arranged on the front side of the rear fixing plate 3; the front abutment surface 12 abuts against the rear wall of the abutment plate 7.
Specifically, the number of the first sliding seats 8 is two, and the two first sliding seats are respectively positioned on the left side and the right side of the bottom plate 6; the two second sliding seats 9 are respectively positioned at the left side and the right side of the backup plate 7.
Specifically, the supporting frame 1 comprises an inverted U-shaped plate 13 and an arc-shaped plate 14 which is convex upwards; two ends of the arc-shaped plate 14 are respectively connected with two ends of the inverted U-shaped plate 13.
Specifically, the first bolt 4 penetrates through the support frame 1 and is in threaded connection with the front fixing plate 2; the second bolt 5 penetrates through the support frame 1 and is in threaded connection with the rear fixing plate 3.
Installation description: when the utility model is installed, the front fixing plate 2 and the rear fixing plate 3 are firstly connected on the seat plate, specifically, the front fixing plate 2 is transversely connected on the first slide seat 8 in a sliding manner, the rear fixing plate 3 is transversely connected on the second slide seat 9 in a sliding manner, and then the front fixing plate 2 and the rear fixing plate 3 are fixed on the two support frames 1, specifically, the first bolt 4 passes through the support frame 1 to be in threaded connection with the front fixing plate 2, and the second bolt 5 passes through the support frame 1 to be in threaded connection with the rear fixing plate 3; after the connection, the left side surface of the seat plate abuts against the support frames 1 on the left side of the seat plate, the right side surface of the seat plate abuts against the support frames 1 on the right side of the seat plate, and the seat plate is limited between the two support frames 1; the utility model discloses an above-mentioned connection can accomplish its installation of installation very convenient, if of course when wanting to dismantle, only need twist first bolt 4 and second bolt 5 to with preceding fixed plate 2 and after-fixing board 3 take out from the seat can, it dismantles also very convenient.
The upper abutting surface 11 is arranged above the front fixing plate 2, the upper abutting surface 11 is tightly attached to the lower wall of the bottom plate 6, the contact surface between the front fixing plate 2 and the bottom plate 6 is increased, and the stress area is increased; the front side of the rear fixing plate 3 is provided with a front abutting surface 12, the front abutting surface 12 is tightly attached to the rear wall of the backup plate 7, the contact surface of the rear fixing plate 3 and the backup plate 7 is increased, and the stress area is increased; through its lifting surface area of increase, when the people sat on the left board, front fixed plate 2 and rear fixed plate 3 were difficult for the atress to gather in a department (the atress is in a phenomenon that the rupture easily appears in a department) when supporting, strengthened its fastness, life increases.
