Referring to fig. 1-5, the present embodiment provides a safety bench, including a seat, where the seat includes a latch 1 and two side plates 5. The fixing shaft 2 and the seat plate 3 are arranged between the two side plates 5, two ends of the fixing shaft 2 are fixedly connected with the inner side walls of the two side plates 5 respectively, and the fixing shaft 2 penetrates through the left side wall and the right side wall of the seat plate 3, so that the seat plate 3 can rotate around the fixing shaft 2. And the bolt 1 in this scheme through the connecting piece with fixed axle 2 rotatable coupling. The upper end face of the seat plate 3 is provided with a first limiting hole, and the lower end face of the seat plate 3 is provided with a second limiting hole. When the plate surface of the seat plate 3 is vertically arranged, the bolt 1 is inserted into the second limiting hole. When the surface of the seat plate 3 is horizontally arranged, the bolt 1 is inserted into the first limiting hole.

In a step classroom, the condition that a student answers questions immediately and the seat plate 3 automatically turns over often occurs, and the seat plate 3 can impact the body of the student to cause damage. And the trainee needs to overturn the seat plate 3 again when going into the seat again, which is troublesome and troublesome, and often, the trainee forgets to overturn the seat plate 3 to cause the trainee to fall down under the condition that the trainee is not careful, thereby having certain danger. In this scheme, when the face level of seat 3 set up, bolt 1 inserts first spacing pore pair seat 3 forms spacingly, prevents that seat 3 from turning automatically, avoids appearing the condition that seat 3 automatic upset strikes student's health and causes the damage, also can not appear under the condition that the student is not noticed, and the student forgets the problem that upset seat 3 leads to the student to fall down, has improved the security of seat greatly. And after the seat plate 3 is turned to be in a vertical state, the bolt 1 is rotated and then inserted into the second limiting hole for limiting. Preventing the seat plate 3 from suddenly turning over and colliding with the passing trainees.

In order to realize that the bolt 1 can rotate around the fixed shaft 2, as a specific implementation manner, in the embodiment, the bolt 1 comprises an insertion rod 11, the connecting member comprises a first connecting plate 12 and a second connecting plate 13, a rotating hole 122 is formed on the first connecting plate 12, and the fixed shaft 2 penetrates through the rotating hole 122 to be rotatably connected with the first connecting plate 12. In order to prevent the bolt 1 from interfering with it during rotation. The first connecting plate 12 is slidably disposed along the longitudinal direction of the stationary shaft 2. The second connecting plate 13 is connected with the outer wall of the insert rod 11, and the first connecting plate 12 is connected with the second connecting plate 13.

Meanwhile, in order to enable the bolt 1 to be inserted into the second limiting hole and the first limiting hole, the bolt 1 and the fixed shaft 2 can be kept fixed. In this embodiment, the fixed shaft 2 is provided with four hole grooves 21 uniformly around the circumference of the fixed shaft 2. The first connecting plate 12 is provided with a cavity 121 inside, the hole surface of the rotating hole 122 is provided with a plurality of through holes 123, and the through holes 123 are communicated with the cavity 121. The head end of the second connecting plate 13 is connected with the inserted link 11, the tail end of the second connecting plate 13 is connected with two pull rods 131, the two pull rods 131 are oppositely arranged relative to the axis of the fixed shaft 2, the head ends of the two pull rods 131 are connected with the lower end face of the second connecting plate 13, the tail ends of the two pull rods 131 are arranged in the cavity 121, each pull rod 131 is provided with a lock tongue 132, and the lock tongue 132 is connected with the side wall of the pull rod 131. The outer wall of the pull rod 131 is sleeved with a spring 133, one side of the spring 133 is connected with the inner wall of the cavity 121, and the other side of the spring 133 is connected with the outer wall of the pull rod 131. When no external force acts, the spring 133 is in a natural state, the insert rod 11 is inserted into the first limiting hole or the second limiting hole, and the lock tongue 132 penetrates through the through hole 123 and is inserted into the hole corresponding to the hole groove 21. When the external force pulls the second connecting plate 13 to lift the pull rod 131, the spring 133 is forced to stretch and the hole wall of the through hole 123 presses the latch 132 into the cavity 121, so as to unlock the lock.

In a further aspect, the upper end face of the second connecting plate 13 is provided with a handle 7. The second connecting plate 13 can be lifted by a sitting person through the handle 7, so that the inserting rod 11 is lifted to unlock, and compared with the situation that the second connecting plate 13 is directly lifted to unlock, the lifting handle 7 is undoubtedly more convenient and faster, and is more labor-saving.

In addition, the inner side walls of the two side plates 5 are provided with limiting plates 6. When the surface of the seat plate 3 is horizontally arranged, the lower end surface of the seat plate 3 is attached to the upper end surface of the limiting plate 6. Carry on spacingly through limiting plate 6 to seat 3, prevent that seat 3 from excessively overturning.

In this embodiment, the seat back further includes a back plate 4, a side wall of the back plate 4 is fixedly connected to the two side plates 5, a positive pole magnet 41 is disposed on a front end surface of the back plate 4, a negative pole magnet 31 is disposed on an upper end surface of the seat plate 3, and the back plate 4 and the seat plate 3 attract each other.

To sum up, the utility model provides a seat, when the student need sit on, pulling handle 7, second connecting plate 13 drive pull rod 131 rises, and the unblock of the lateral wall oppression spring bolt 132 of hole, and inserted bar 11 extracts from the spacing hole of second, and bolt 1 and seat 3 separate, remove spacingly. The bolt 1 is then slid and the seat plate 3 is rotated against the stop plate 6. Sliding the bolt 1 again, aligning the inserted bar 11 with the first spacing hole, loosening the handle 7, the spring 133 retracts, the inserted bar 11 automatically inserts into the first spacing hole to lock the bolt 1 with the seat plate 3, the bolt 132 slides into the hole groove 21 to lock the bolt 1 with the fixed shaft 2, and finally the seat plate 3 is locked with the fixed shaft 2, because the fixed shaft 2 is fixedly connected with the side plate 5, the seat plate 3 is locked with the side plate 5, namely the position of the seat plate 3 is fixed, the seat plate 3 is prevented from automatically turning over, and the situation that the body of a student is impacted by the seat plate 3 to cause damage is avoided. When the student leaves the field, the student only needs to pull the handle 7, the second connecting plate 13 drives the pull rod 131 to ascend, the side wall of the hole presses the bolt 132 to unlock, the inserting rod 11 is pulled out from the first limiting hole, and after the bolt 1 slides, the seat plate 3 automatically overturns to be attached to the backup plate 4 because the backup plate 4 and the seat plate 3 attract each other. At this moment, the bolt 1 slides again, the inserting rod 11 is aligned with the second limiting hole, the handle 7 is loosened, the spring 133 retracts, the inserting rod 11 is automatically inserted into the second limiting hole, so that the bolt 1 and the seat plate 3 are locked, the seat plate 3 is prevented from being overturned and impacting passing students, and the safety of the seat is greatly improved.

In the present embodiment, the number of the seats is plural, and the plural seats are arranged in the same horizontal direction. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
