Description
Technical Field
The utility model relates to a student safety seat.
Background
In a campus, chairs are common appliances, and for older students, their safety can be substantially eliminated. However, for students of small ages, especially for students in a kindergarten, the students may collide with the seat and easily injure the infant.
The existing seat of a kindergarten is usually composed of a seat panel, seat legs and a seat back, wherein the seat panel is respectively fixed with the seat legs and the seat back, and the height position of the top of the seat back is basically the same as the height of an infant or close to the height position of the seat back, so that the head or other parts of the infant easily collide with the seat back under the condition of carelessness of the infant, and the infant is injured. There is therefore a need for an improved solution for such seats.
SUMMERY OF THE UTILITY MODEL
The utility model provides a student safety seat avoiding colliding with the head of a human body.
The technical scheme for realizing the purpose is as follows:
student's safety seat, including seat panel, back of the chair, still include:
a bottom support arranged in a lateral direction of the seat;
the first guide rail bracket and the second guide rail bracket are respectively and fixedly connected with the bottom support;
the first lifting frame is in sliding fit with the first guide rail frame, and the chair back is fixed with the first lifting frame;
the second lifting frame is in sliding fit with the second guide rail frame, and the seat panel is fixed with the second lifting frame;
and the lever mechanism is fixed with the second guide rail frame and is also matched with the first lifting frame and/or the second lifting frame.
When no gravity acts on the seat panel, the chair back moves downwards along the first guide rail frame under the action of the gravity of the chair back, at the moment, the chair back drives the lever mechanism to rotate anticlockwise, the lever mechanism drives the second lifting frame to move upwards, so that the seat panel rises, and the chair back and the seat panel reach balance and do not move when the chair back and the top surface of the seat panel are at the same height. The structure has the advantage that when no gravity acts on the seat panel, the seat back can automatically descend, so that the potential collision danger of the seat back at a higher position on the head or other parts of a person is avoided.

Detailed Description
As shown in fig. 1 to 4, the safety seat for students of the present invention comprises a seat panel 1, a seat back 2, a bottom support 3 transversely disposed along the seat, a first guide rail frame 4 and a second guide rail frame 5 longitudinally disposed along the seat, a first lifting frame 6, a second lifting frame 7, and a lever mechanism 8, wherein the first guide rail frame 4 and the second guide rail frame 5 are respectively fixedly connected with the bottom support 3; the first lifting frame 6 is in sliding fit with the first guide rail frame 4, and the chair back 2 is fixed with the first lifting frame 6; the second lifting frame 7 is in sliding fit with the second guide rail frame 5, and the seat panel 1 is fixed with the second lifting frame 7; the lever mechanism 8 is fixed with the second guide rail bracket 5, and the lever mechanism 8 is also matched with the first lifting bracket 6 and/or the second lifting bracket 7.
As shown in fig. 1, when gravity (for example, the weight of a human body) acts on the seat panel 1, the gravity is transmitted to the second lifting frame 7 through the seat panel 1, so that the second lifting frame 7 moves downward (as viewed from the figure), and the lever mechanism 8 rotates clockwise, and the lever mechanism 8 drives the seat back 2 to move upward, so that the seat back 2 is automatically lifted (as shown in fig. 1), and if a person sits on the seat panel 1 at this time, the person can rely on the automatically lifted seat back 2.
As shown in fig. 1 and 4, when no gravity acts on the seat panel 1, the seat back 2 moves downward along the first rail bracket 4 under the action of its own gravity, at this time, the seat back 2 drives the lever mechanism 8 to rotate counterclockwise, and the lever mechanism 8 drives the second lifting bracket 7 to move upward, so that the seat panel 1 rises, and the state of preference is that when the seat back 2 and the top surface of the seat panel 1 are at the same height (as shown in fig. 4), the seat back 2 and the seat panel 1 reach a balance and do not move any more. The advantage of this kind of structure is that, when there is not the gravity effect on seat panel 1, back of the chair 2 can descend automatically to avoid back of the chair 2 to be in higher position and form potential collision danger to people's head or other parts.
As shown in fig. 2 and 3, the carriage 3 includes a base plate 30, and the first rail bracket 4 and the second rail bracket 5 are fixed to the base plate 30, respectively; or the support 3 comprises a bottom plate supporting part 31, and the first guide rail bracket 4 and the second guide rail bracket 5 are respectively fixed with the supporting part 31; or the support 3 includes a base plate 30 and a support member 31, the support member 31 is fixed to the base plate 30, and the first rail frame 4 and the second rail frame 5 are respectively fixed to the support member 31.
