Detailed Description

The present invention will be described in further non-limiting detail with reference to the following preferred embodiments and accompanying drawings.

The first embodiment is as follows:

as shown in fig. 1 to 4, the turnover fixing mechanism according to a preferred embodiment of the present invention includes a connection block 1 and a rotation block 2 rotatably connected to the connection block 1. Rotatory piece 2 includes rotating assembly 20, is provided with a plurality of female teeth 21 on rotating assembly 20, and connecting block 1 includes adjusting part 10 and stirs the drive assembly that adjusting part 10 removed, is provided with the public tooth 11 with female tooth 21 adaptation on the adjusting part 10, and drive assembly stirs public tooth 11 and breaks away from or meshes in female tooth 21, realizes the unblock or the locking between connecting block 1 and rotatory piece 2.

Connecting block 1 includes connecting block casing 12, installs second pivot 14 on connecting block casing 12, and rotating assembly 20 cover is established outside second pivot 14, makes swivelling joint between connecting block 1 and the rotatory piece 2.

As shown in fig. 6 and 7, the driving assembly includes a button 32, a boss 31 disposed on the adjusting assembly 10, and a transmission block 33 rotatably disposed between the button 32 and the boss 31, and pressing the button 32 controls the transmission block 33 to rotate and poke the boss 31 to disengage the male teeth 11 from the female teeth 21, so as to unlock the connecting block 1 and the rotating block 2.

Further, the button 32 includes a pressing portion 321, and a transmission portion 322 and a reset portion 323 connected to the pressing portion 321, wherein the pressing portion 321 is exposed outside the connecting block housing 12; the transmission portion 322 is disposed between the pressing portion 321 and the transmission block 33; a first spring 324 is disposed between the reset portion 323 and the connector block housing 12 for providing a restoring force after releasing the button 32 to cause the button 32 to spring back to an initial position.

The transmission block 33 includes a first rotating shaft 331 installed on the connecting block housing 12 and a turning block 332 disposed outside the first rotating shaft 331, the turning block 332 includes a first abutting portion 3321 and a second abutting portion 3322, wherein the first abutting portion 3321 is connected to the transmission portion 322 of the button 32, and the second abutting portion 3322 is connected to the boss 31.

A second spring 13 is disposed between the adjusting assembly 10 and the connecting block housing 12 for providing a restoring force to the adjusting assembly 10 after the button 32 is released, so that the male teeth 11 are engaged with the female teeth 21, thereby achieving locking between the connecting block 1 and the rotating block 2.

As shown in fig. 5, the female teeth 21 include an upper female tooth 21a and a lower female tooth 21b, and the upper female tooth 21a and the lower female tooth 21b are arranged up and down and are staggered with each other. In the present embodiment, the number of the female teeth 21 is preferably 9, and the female teeth are arranged up and down and staggered with each other, the number of the upper female teeth 21a is 5, and the number of the lower female teeth 21b is 4, so that the rotation angle of the hand rotating block 2 is 0 to 90 °, and there are 9 engagement angles in total.

Correspondingly, the adjusting assembly 10 also comprises an upper adjusting assembly 10a and a lower adjusting assembly 10b which have the same structure, wherein the upper adjusting assembly 10a is matched with the upper female tooth 21a, and the lower adjusting assembly 10b is matched with the lower female tooth 21 b. Therefore, only one male tooth 11 of the adjusting assembly 10 is caught in the female tooth 21 during the engagement, so that the engagement between the male tooth 11 and the female tooth 21 is subdivided, and the number of engaged angles can be increased while ensuring sufficient tooth strength.

As shown in fig. 6 and 7, when the connection block needs to be turned over, the push button 32 is pressed, the transmission part 322 presses the first abutting part 3321 of the turning block 332, the turning block 332 rotates around the first rotating shaft 331, so that the second abutting part 3322 presses the boss 31, the adjustment assembly 10 moves outwards, the male teeth 11 are disengaged from the female teeth 21, the connection block 1 and the rotation block 2 are unlocked, and the rotation block 2 can rotate freely and drive all the components mounted on the rotation block to rotate.

When the locking is required after the rotation, as shown in fig. 8 and 9, the button 32 is released, and the button 32 is rebounded to the original position by the restoring force of the first spring 324; and the adjusting assembly 10 moves back under the restoring force of the second spring 13, so that the male teeth 11 are engaged with the female teeth 21, and the locking between the connecting block 1 and the rotating block 2 is realized. At this time, the first contact portion 3321 loses its pressure, and the second contact portion 3322 rotates the turning block 332 about the first axis 331 in the opposite direction to that when the push button is pushed down by the pressure of the boss 31.

Example two:

in this embodiment, the turnover fixing mechanism is substantially the same as the first embodiment, except that the button 32 and the transmission block 33 are eliminated, and the shape of the boss 31 is modified to expose the boss 31 outside the connecting block housing 12, so that an operator can directly stir the boss 31 to drive the adjusting assembly 10 to move outwards, so that the male teeth 11 are separated from the female teeth 21, and the unlocking between the connecting block 1 and the rotating block 2 is realized.

When needs overturn, operating personnel directly stir boss 31, make adjusting part 10 move outward, make public tooth 11 break away from in female tooth 21, realize the unblock between connecting block 1 and rotatory piece 2, and rotatory piece 2 alright with free rotation to it is rotatory to drive all parts of installing on rotatory piece.

When the locking is needed after the rotation, the operator releases the boss 31, and the adjusting assembly 10 moves back under the restoring force of the second spring 13, so that the male teeth 11 are engaged with the female teeth 21, and the locking between the connecting block 1 and the rotating block 2 is realized.

The turning fixing mechanism in the two embodiments is preferably used on a leg plate of an operating bed, wherein the connecting block 1 is specifically an operating bed connecting block, and the rotating block 2 is specifically a leg plate rotating block.

According to the leg plate of the operating bed and the overturning fixing mechanism thereof, the driving part is adopted to control the male teeth on the adjusting assembly to be disengaged or engaged with the female teeth on the rotating assembly during overturning, so that quick unlocking and locking are realized, the operation is simple, and no effort is required. Specifically, the driving part is matched with a button, a transmission block and a boss, unlocking between the connecting block and the rotating block is realized by pressing the button, and the locking is automatically realized after releasing the button, so that an operator can realize quick unlocking and locking only by using one finger for operation; in another embodiment, the driving part adopts an exposed boss, and an operator directly stirs the boss to enable the male teeth to be separated from or meshed with the female teeth, so that the structure design is simple, and the cost is minimized. The mechanism is also provided with a plurality of preset fixed angles, and the requirements of operators can be met.

It should be noted that the above-mentioned preferred embodiments are merely illustrative of the technical concepts and features of the present invention, and are intended to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
