Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The first embodiment:

as shown in fig. 1-4, the electronic information board fixing device comprises a bracket 1, a fixing seat 2, a clamping rod 3 and a clamping seat 4, the fixed seat 2 is fixed on the top of the bracket 1, the top of the fixed seat 2 is provided with a fixed groove 21, the fixing groove 21 is internally provided with a clamping pad 22, the clamping rod 3 is arranged at the upper side and the lower side in the fixing seat 2 in a penetrating way, the clamping rods 3 are connected with the fixed seat 2 in a sliding way, the clamping rods 3 at two sides respectively extend out of two sides of the fixed seat 2, a rack 31 is arranged on the inner side of the clamping rod 3, a gear 32 is arranged between the racks 31 on the two sides, the gear shaft of the gear 32 extends out of the fixed seat 2 and is connected with a knob 33, a ratchet wheel 34 is arranged on the gear shaft of the gear 32, a pawl 35 is arranged at the rear side of the fixed seat 2 corresponding to the upper end of the ratchet wheel 34, the pawl 35 is engaged with the ratchet wheel 34, the holder 4 is fixed at the end of the clamping rod 3 through an L-shaped rod 41, and a spring 42 is arranged at one side of the connecting end of the L-shaped rod 41 and the holder 4.

Preferably, the fixing groove 21 is a tapered groove with a wide top and a narrow bottom, so that electronic information boards with different thicknesses can be inserted and fixed in the fixing groove 21 under the action of the clamping pad 22.

Preferably, the clamping pad 22 is a rubber pad.

Preferably, a torsion spring 36 is provided on the rotation shaft of the pawl 35, and the torsion spring 36 allows the pawl 35 to be engaged with the ratchet teeth of the ratchet 34 in a relatively compact manner, so that the pawl is not easily loosened.
