Therefore, the features defined with "first", "second", etc. can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly and specifically limited.

[0031] Please refer to Figures 1 to 6 , the quick disassembly and assembly structure 100 provided by the embodiment of the present application will be described. The quick disassembly and assembly structure 100 is used to realize the detachable connection of two connected parts, for example, the quick disassembly and assembly structure 100 is applied to a sickbed, and the quick disassembly and assembly structure 100 can realize the quick positioning and installation of an accessory 200 of the sickbed on a bed body 300. The accessory 200 can be an extension plate, a headrest or an infusion support, etc.

[0032] Please refer to Figure 3 and Figure 4 , the quick disassembly and assembly structure 100 includes a fixing part 10 and a push piece 20, the fixing part 10 is provided with a positioning groove 111, the push piece 20 is rotatably connected with the fixing part 10, the push piece 20 is provided with a protrusion 30, the protrusion 30 is correspondingly arranged with the positioning groove 111, and the protrusion 30 can press the part inserted into the positioning groove 111.

[0033] The positioning groove 111 is used for inserting the part, when the quick disassembly and assembly structure 100 is applied to a sickbed, the part inserted into the positioning groove 111 can be part of the bed body or part of the accessory, for example, when the part inserted into the positioning groove 111 is part of the bed body, the fixing part 10 is used to be fixed on the accessory 200 of the sickbed. Or, when the part inserted into the positioning groove 111 is part of the accessory, the fixing part 10 is used to be fixed on the bed body 300 of the sickbed.

[0034] Since the push piece 20 is rotatably connected with the fixing member 10, the convex 30 can be switched between the locking position and the unlocking position by pushing the push piece 20, and when the convex 30 is in the locking position, the convex 30 is correspondingly arranged with the positioning groove 111, so that the convex 30 can press the component inserted into the positioning groove 111, so that the two connected members can be detachably connected. Wherein, when the convex 30 is in the locking position, the convex 30 is correspondingly arranged with the positioning groove 111, which means that when the convex 30 is in the locking position, the convex 30 can press the component inserted into the positioning groove 111 on the fixing member 10, that is, the convex 30 is clamped on the component inserted into the positioning groove 111 by cooperating with the fixing member 10.

[0035] For example, the accessory 200 is an extension plate which is detachably connected with one end of the bed body 300 through the quick disassembly structure 100, and is used for supporting the head and shoulder of the patient during radiotherapy. The extension plate is made of carbon fiber and has high strength and ray transmittance. Specifically, the fixing member 10 and the extension plate can be adhered together by using structural adhesive. In addition, in order to enhance the reliability of the connection between the fixing member 10 and the extension plate, a plastic screw can also be used to reinforce the connection between the fixing member 10 and the extension plate. Of course, the fixing member 10 and the extension plate can also be directly fixed together by using a plastic screw. Then, the edge of the one end of the bed body 300 is inserted into the positioning groove 111 to quickly position the extension plate. The push piece 20 is pushed to rotate the push piece 20 relative to the fixing member 10, and the push piece 20 drives the convex 30 to rotate. When the convex 30 rotates to the locking position, the convex 30 presses the edge of the bed body 300 inserted into the positioning groove 111 on the fixing member 10, thereby quickly installing the extension plate on the bed body 300. When it is needed to dismount the extension plate, the push piece 20 is pushed in the opposite direction to drive the convex 30 to rotate in the opposite direction. When the convex 30 rotates to the unlocking position, the convex 30 releases the pressing on the bed body 300, and then the edge of the bed body 300 is separated from the positioning groove 111, thereby quickly dismounting the extension plate from the bed body 300.

[0036] The quick dismounting structure 100 provided by the application is compared with the prior art, and parts inserted into the positioning groove 111 are parts of the hospital bed body 300. For example, the fixing part 10 is used for fixing the accessory 200 of the hospital bed. By inserting the parts of the hospital bed body 300 into the positioning groove 111, the accessory 200 is conveniently positioned. By arranging the protrusion 30 on the push piece 20, the protrusion 30 is driven by the push piece 20 to rotate from the unlocking position to the locking position by pushing the push piece 20, so that the protrusion 30 presses the part of the hospital bed body 300 inserted into the positioning groove 111 on the fixing part 10, to realize that the accessory 200 is installed on the hospital bed body 300. When dismounting, the push piece 20 is only reversely rotated, the protrusion 30 is driven by the push piece 20 to rotate from the locking position to the unlocking position, so that the protrusion 30 releases the pressing of the hospital bed body 300, at this time, the accessory 200 can be dismounted. In this way, the accessory 200 is quickly positioned by the positioning groove 111, the protrusion 30 is switched between the locking position and the unlocking position by pushing the push piece 20, the accessory 200 is quickly installed and dismounted, no additional tool is needed, the operation is convenient, time and labor are saved, and the dismounting efficiency is improved.

[0037] In some embodiments of the application, referring to Figure 5 The positioning groove 111 is a semi-closed groove, the positioning groove 111 is provided with a first opening 112, a second opening 113, a first side wall 114 and a second side wall 115, the first opening 112 and the second opening 113 are arranged adjacent to each other and communicate with each other, the first side wall 114 is arranged opposite to the first opening 112, and the second side wall 115 is arranged opposite to the second opening 113. It can be understood that the first side wall 114 and the second side wall 115 are arranged adjacent to each other.

[0038] For example, the fixing part 10 is fixed on the accessory 200, and the accessory 200 needs to be positioned on the hospital bed body 300. The first opening 112 and the second opening 113 are aligned with the adjacent two side edges of the hospital bed body 300, the fixing part 10 is pushed, the adjacent two side edges of the hospital bed body 300 are inserted into the positioning groove 111 from the first opening 112 and the second opening 113 respectively, and when the hospital bed body 300 abuts against the first side wall 114 and the second side wall 115, it indicates that the hospital bed body 300 is inserted into the positioning groove 111 in place.

[0039] The above technical scheme is convenient for the parts of the hospital bed body 300 or the accessory 200 to be quickly inserted into the positioning groove 111 by cooperation of the first opening 112 and the second opening 113, the parts of the hospital bed body 300 or the accessory 200 are abutted by the first side wall 114 and the second side wall 115, the hospital bed body 300 or the accessory 200 is quickly and stably positioned, the operation of the medical staff is facilitated, and the stability of the hospital bed body 300 or the accessory 200 inserted into the positioning groove 111 is improved.

[0040] In some embodiments of the present application, please refer to Figure 4 and Figure 6 The dial 20 has a connecting end 21 and an operating end 22, the connecting end 21 and the operating end 22 are two ends of the dial 20 along its own length, that is, the operating end 22 is arranged opposite to the connecting end 21, the connecting end 21 is rotatably connected with the fixing part 10, and the protrusion 30 is arranged on the connecting end 21.

[0041] Optionally, the protrusion 30 is integrally formed with the connecting end 21 to form a cam-like structure.

[0042] In use, medical staff rotates the dial 20 by dialing the operating end 22, and the connecting end 21 is rotatably connected with the fixing part 10, one end of the dial 20 away from the connecting end 21 is arranged as the operating end 22, the operating end 22 is far away from the connecting end 21, according to the principle of lever, the medical staff is easy to dial the dial 20 from the operating end 22, which saves labor.

[0043] In some embodiments of the present application, please refer to Figure 4 and Figure 6 The operating end 22 is curved. By arranging the operating end 22 to be curved, the ergonomics is met, and the medical staff is facilitated to dial the operating end 22.

[0044] In some embodiments of the present application, please refer to Figure 3 and Figure 4 The quick disassembly and assembly structure 100 further comprises a top plate 40, the top plate 40 is located on one side of the protrusion 30 facing the positioning groove 111 and is in sliding fit with the fixing part 10, and the contact surface of the top plate 40 is greater than the contact surface of the protrusion 30.

[0045] The contact surface of the top plate 40 refers to the range directly contacted by the top plate 40 and the bed body 300 or the accessory 200, and the contact surface of the protrusion 30 refers to the range directly contacted by the protrusion 30 and the top plate 40 when the protrusion 30 is in the locking position.

[0046] When part of the bed body 300 or the accessory 200 is inserted into the positioning groove 111, the dial 20 is dialed, and in the process that the protrusion 30 is rotated from the unlocking position to the locking position by the dial 20, the protrusion 30 pushes the top plate 40 to slide in the direction of the positioning groove 111, and when the protrusion 30 is switched to the locking position, the protrusion 30 abuts against the top plate 40, so that the top plate 40 is in contact and abutment with the part of the bed body 300 or the accessory 200 inserted into the positioning groove 111, to press the bed body 300 or the accessory 200 on the fixing part 10.

[0047] The above technical solution, by positioning the top plate 40 on the side of the protrusion 30 facing the positioning groove 111 and slidingly cooperating with the fixing member 10, during the process of the protrusion 30 rotating from the unlocked position to the locked position, the protrusion 30 pushes the top plate 40 to slide in the direction of the positioning groove 111. When the protrusion 30 switches to the locked position, the protrusion 30 abuts against the top plate 40, so that the top plate 40 abuts against the bed body 300 or the accessory 200, which is beneficial to improving the stability of pressing the bed body 300 or the accessory 200 against the fixing member 10, and at the same time effectively avoiding the protrusion 30 directly abutting against the bed body 300 or the accessory 200 and causing damage to the bed body 300 or the accessory 200 due to concentrated force.

[0048] In some embodiments of this application, please refer to Figure 4 When the quick disassembly structure 100 is in a vertical state, the top plate 40 is located above the protrusion 30 and slides with the fixing member 10 along the vertical direction.

[0049] The quick disassembly structure 100 being in a vertical state refers to a state in which the positioning groove 111 is located above the paddle 20 .

[0050] When the accessory 200 is installed on the bed 300 through the quick disassembly structure 100, the quick disassembly structure 100 is in a vertical state, and the top plate 40 is located above the protrusion 30. In this way, when the protrusion 30 switches from the locked position to the unlocked position, the top plate 40 can move downward under the action of its own gravity and release the contact with the bed 300 or the accessory 200. No external force or additional parts are required to reset the top plate 40, which is convenient for medical staff to operate. At the same time, it reduces the parts of the quick disassembly structure 100 and simplifies the structure.

[0051] It should be noted that, in other embodiments, an elastic member may be provided between the top plate 40 and the fixing member 10 , so that when the protrusion 30 switches from the locked position to the unlocked position, the top plate 40 is quickly reset under the action of the elastic member.

[0052] In some embodiments of this application, please refer to Figure 4 and Figure 5 The fixing member 10 is provided with a slide groove 121, which is connected to the positioning groove 111, and the top plate 40 is slidably arranged in the slide groove 121. The top plate 40 slides in the slide groove 121 under the push of the protrusion 30, and at least a portion of the top plate 40 can extend into the positioning groove 111 through the slide groove 121.

[0053] The above technical solution realizes sliding cooperation between the top plate 40 and the fixing member 10 by slidingly setting the top plate 40 in the sliding groove 121 , and at the same time limits the top plate 40 by the sliding groove 121 to prevent the top plate 40 from being separated from the fixing member 10 .

[0054] In some embodiments of the present application, a guide rail is provided on the inner wall of the slide groove 121, and a guide groove is provided on the top plate 40, or a guide groove is provided on the inner wall of the slide groove 121, and a guide rail is provided on the top plate 40. The cooperation between the guide groove and the guide rail is beneficial to enhance the stability of the sliding cooperation between the top plate 40 and the fixing member 10, and prevent the top plate 40 from shaking during the sliding process.

[0055] In other embodiments of the present application, a dovetail groove may be provided on one of the fixing member 10 and the top plate 40, and a dovetail slide rail may be provided on the other of the fixing member 10 and the top plate 40, so that the top plate 40 is slidably provided on the fixing member 10 by sliding the dovetail slide rail into the dovetail groove.

[0056] In some embodiments of this application, please refer to Figure 4 and Figure 5 The connecting end 21 and the protrusion 30 are both received in the slide groove 121. The fixing member 10 is provided with a limiting groove 122 that communicates with the slide groove 121. When the protrusion 30 is in the locked position, the paddle 20 is limited by the limiting groove 122, and the operating end 22 extends from the limiting groove 122. When the protrusion 30 is in the unlocked state, the operating end 22 of the paddle 20 extends from the side of the slide groove 121 away from the positioning groove 111.

[0057] The above technical solution, by accommodating both the connecting end 21 and the protrusion 30 in the slide groove 121, has a reasonable layout and a compact structure, which is conducive to miniaturization of the quick disassembly and assembly structure 100, and by hiding most of the paddle 20 and the protrusion 30 in the slide groove 121, it is conducive to beautifying the appearance of the quick disassembly and assembly structure 100. In addition, when the protrusion 30 is in the locked position, the paddle 20 is limited by the limiting groove 122, so that the paddle 20 cannot drive the protrusion 30 to continue to rotate, so that the protrusion 30 can stably abut against the top plate 40, and the operating end 22 extends out of the limiting groove 122, which is convenient for medical personnel to paddle the operating end 22 and facilitates medical personnel's operation.

[0058] In some embodiments of this application, please refer to Figure 4 and Figure 5 The fixing member 10 includes a positioning portion 11 and a mounting portion 12 provided on one side of the positioning portion 11 in the thickness direction.
