Detailed Description

The technical scheme of the present invention is further described in non-limiting detail below with reference to the preferred embodiments and the accompanying drawings.

As shown in fig. 1, the table top fixing mechanism of the operation table according to a preferred embodiment of the present application includes a tooth holder 2 mounted on a base 1 and a fixing mechanism 4 connected to the table top.

A plurality of tooth grooves 20 are formed on the tooth holder 2at equal intervals.

With further reference to fig. 2 and 3, the fixing mechanism 4 includes a seat arm 40 connected to the table, and a slide rail 41 is connected to a side surface of the seat arm 40, where the slide rail 41 is connected to the base 1, and the slide rail 41 can facilitate movement of the table. A moving groove 43 is formed in the lower surface 42 of the seating arm 40.

The fixing mechanism 4 further includes a latch 44 and a spring 45 mounted in the moving groove 43. The latch tongue 44 has a cross shape and includes a main body 48 and extension portions 46 extending from both sides of the main body 48, and the spring 45 is installed between the extension portions 46 and an inner bottom surface 47 of the moving groove 43, which pushes the latch tongue 44 toward the tooth holder 2. The moving groove 43 includes a base groove 43a and a through groove 43b communicating to the outside of the seat arm 40, the width of the base groove 43a being larger than the width of the through groove 43 b. The extension 46 is slidably fitted in the base groove 43a, and the front end of the main body 48 is located in the through groove 43b, and extends outside the seat arm 40 through the through groove 43 b.

The number of springs 45 is two, which are separated by a main body portion 48, a boss 49 is arranged on the inner bottom surface 47 of the base groove 43a, preferably the width of the boss 49 is consistent with the width of the main body portion 48, which is also used for separating the two springs 45 to facilitate the positioning of the springs, meanwhile, when the spring tongue 44 is retracted into the moving groove 43, the boss 49 can prop against the spring tongue 44 to limit the limiting position of the retraction of the spring tongue 44, unnecessary force application of hands is reduced, and in order to further limit the position of the spring 45, referring to fig. 4, downward-sinking matching grooves 43c are arranged on two sides of the base groove 43a, and the spring 45 is partially accommodated in the matching grooves 43c to reduce left-right displacement.

As shown in fig. 5 and 6, the fixing mechanism 4 further includes a cover plate 50 covering the moving groove 43 and an operating handle 51 slidably coupled with the cover plate 50. The cover plate 50 is fixedly attached to the seat arm 40 by screws 57.

With further reference to fig. 7, the operating handle 51 is connected with the lock tongue 44 by a bolt 52, a countersunk hole 53 is formed in the operating handle 51, a threaded hole 44a is formed in the lock tongue 44, and the bolt 52 is disposed in the countersunk hole 53 and connected with the threaded hole 44a through the cover plate 50. The bottom surface 51a of the operating handle 51 is provided with a spacing block 54 protruding towards the lock tongue 44, the cover plate 50 is provided with a first long hole 50b for the spacing block 54 to pass through, when the operating handle 51 is connected to the lock tongue 44, the spacing block 54 passes through the first long hole 50b to prop against the lock tongue 44, so that the operating handle 51 is prevented from pressing the cover plate 50, and the defect of unsmooth movement of the operating handle 51 is avoided.

Two protruding sliding blocks 51b are arranged on the bottom surface 51a of the operating handle 51, the sliding blocks 51b are matched with two second long holes 50a formed in the cover plate 50, and the sliding blocks 51b can move along the second long holes 50 a.

When the operation handle 51 is pulled in the direction away from the base 1, the operation handle 51 drives the lock tongue 44 to compress the spring 45 so that the lock tongue 44 is separated from the tooth groove 20, at the moment, the table top can move smoothly, when the table top moves to a proper position, the operation handle 51 is released, the spring 45 pushes the lock tongue 44 to extend into the tooth groove 20 at the corresponding position in the process of restoring deformation (if the lock tongue 44 fails to extend into the tooth groove 20, the table top only needs to move slightly left and right, and the lock tongue 44 can extend into the tooth groove 20 at the adjacent position), so that the locking of the table top is completed. In the operation process, the hand only needs to pull the operation handle 51 outwards, the torsion is not needed, the operation is very handy, and the force application is convenient.

In order to further improve the comfort of use, the operating handle 51 is provided with a convex holding part 55, one surface of the holding part 55 close to the base 1 is an inward cambered surface 56, and the degree of fit with fingers is higher, so that the force application and the operation are more convenient.

The fixing mechanism of the operating table top at least has the following advantages:

It should be noted that the foregoing description of the preferred embodiments is merely illustrative of the technical concept and features of the present invention, and is not intended to limit the scope of the invention, as long as the scope of the invention is defined by the claims and their equivalents. All equivalent changes or modifications made in accordance with the spirit of the present invention should be construed to be included in the scope of the present invention.
