[0031] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0032] First Embodiment

[0033] like Figure 1 and Figure 2 As shown, the quick-installation structure 100 includes:

[0034] Pin 110, which is used to connect to the support member 200;

[0035] Plate 120 is used to connect to mounting part 300. The plate 120 has a sliding groove 121. The opening of the sliding groove 121 is exposed on the edge of the plate 120. After the opening of the sliding groove 121 is aligned with the pin 110, the pin 110 slides into the sliding groove 121.

[0036] A connecting shaft 130 is inserted into the plate 120 and the support member 200.

[0037] The support member 200 is provided with a pin 110, and the mounting member 300 is provided with a plate 120. The mounting member 300 with the plate 120 is moved so that the groove 121 on the plate 120 is aligned with the pin 110. Then, the mounting member 300 is moved further so that the pin 110 slides into the groove 121. Then, the connecting shaft 130 is inserted into the plate 120 and the support member 200 to complete the installation of the mounting member 300 on the support member 200. The operation is convenient and effectively improves the installation efficiency.

[0038] like Figure 1 As shown, the plate 120 and the mounting component 300 can be connected together by welding or other means. Therefore, the plate 120 and the mounting component 300 are considered as a whole and are fixed to the support component 200. Similarly, the pin 110 and the support component 200 can also be integrated.

[0039] like Figure 1 As shown, the plate 120 has a sheet-like structure and is relatively thin. The groove 121 extends through the plate 120 along its thickness direction.

[0040] The pin 110 is a columnar structure, and its length is slightly greater than the thickness of the plate 120. The top end of the pin 110 is provided with a limiting top plate 1101, and the bottom end of the pin 110 is connected to the support member 200, so that after the mounting member 300 is installed on the support member 200, the plate 120 can be held between the limiting top plate 1101 and the support member 200, preventing the plate 120 from moving out from the top end of the pin 110.

[0041] like Figure 1As shown, the number of slide grooves 121 and the number of pins 110 are equal and correspond one-to-one. In this embodiment, there are two slide grooves 121, namely a front slide groove 121a and a lower slide groove 121b. The opening of the front slide groove 121a is exposed on the front side of the edge of the plate body 120, and the opening of the lower slide groove 121b is exposed on the lower side of the edge of the plate body 120. There are also two pins 110, namely a front pin 111 and a lower pin 112. The front pin 111 is located in front of the lower pin 112. The front pin 111 is adapted to the front slide groove 121a, and the lower pin 112 is adapted to the lower slide groove 121b.

[0042] During installation, the mounting component 300 is tilted relative to the support component 200, aligning the opening of the front sliding groove 121a with the front pin 111. As the front pin 111 slides into the front sliding groove 121a, the mounting component 300 is moved downwards around the front pin 111 until the lower pin 112, aligned with the opening of the lower sliding groove 121b, slides into the lower sliding groove 121b, thus completing the pre-fixation of the mounting component 300 on the support component 200. Compared to the bolt fixing method in the prior art, installers can install the mounting component 300 on the support component 200 themselves without any assistance, effectively improving installation efficiency and making the entire installation process more convenient and efficient.

[0043] To meet the above adaptation requirements, the sliding groove 121b extends in a straight line from its opening to its bottom, with the opening of the groove lower than the bottom. That is, the mounting member 300 moves downward relative to the support member 200, allowing the lower pin 112 to enter the sliding groove 121b from bottom to top, so that the lower pin 112 rests against the bottom of the sliding groove 121b.

[0044] Similarly, the front slide groove 121a extends from the opening of the front slide groove 121a to the bottom of the front slide groove 121a in the form of an arc and a straight line, so that the front pin 111 abuts against the bottom of the front slide groove 121a.

[0045] It should be noted that the length, width, distance and other dimensions of the front sliding groove 121a and the lower sliding groove 121b can be adjusted according to design requirements so that when the front pin 111 slides into the front sliding groove 121a, the groove opening of the lower sliding groove 121b can correspond to the lower pin 112, so that the lower pin 112 slides into the lower sliding groove 121b.

[0046] Preferably, the width of the opening of the front slide groove 121a gradually increases from the inside to the outside, so as to facilitate the front pin 111 sliding into the front slide groove 121a from the opening of the front slide groove 121a. Similarly, the width of the opening of the lower slide groove 121b gradually increases from the inside to the outside.

[0047] like Figure 1 As shown, the plate 120 has a plate through hole 122, the support member 200 has a support member through hole 200a, and the connecting shaft 130 is inserted into the plate through hole 122 and the support member through hole 200a.

[0048] The plate through-hole 122 extends through the plate 120 along its thickness direction, and the support through-hole 200a also extends through the support 200. The connecting shaft 130 can be sequentially inserted into the support through-hole 200a and the plate through-hole 122 from the inside of the support 200. In this case, the pin 110 is connected to the outside of the support 200, and the plate 120 of the mounting member 300 is adapted to the pin 110 on the outside of the support 200. Alternatively, the connecting shaft 130 can be sequentially inserted into the plate through-hole 122 and the support through-hole 200a from the outside of the support 200.

[0049] The connecting shaft 130 is adapted to the shapes of the plate through hole 122 and the support through hole 200a, respectively, and the cross-sections of the three can be circular, square, etc. The connecting shaft 130 is connected to the plate through hole 122 and the support through hole 200a by means of screwing, sleeve, etc.

[0050] like Figure 3 As shown, the connecting shaft 130 is positioned inside the support member 200 in a manner that overcomes the elastic force of the spring 140.

[0051] The connecting shaft 130 is integrally connected to the inner side of the support member 200, and under the action of the spring 140, the bottom of the connecting shaft 130 protrudes outward from the outer side of the support member 200. When the plate 120 moves outward from the support member 200, the plate 120 can squeeze the connecting shaft 130, causing the connecting shaft 130 to move inward from the support member 200. Therefore, the connecting shaft 130 will not interfere with the movement of the plate 120 outward from the support member 200. After the plate through hole 122 on the plate 120 aligns with the connecting shaft 130, the connecting shaft 130 is inserted into the plate through hole 122 under the restoring force of the spring 140. It can be seen that the insertion of the connecting shaft 130 into the plate through hole 122 and the support member through hole 200a respectively does not require additional manual intervention, effectively improving installation efficiency.

[0052] It should be noted that the plate through hole 122 is located on the rear side of the sliding groove 121b. As the mounting part 300 moves down around the front pin 111, the plate through hole 122 can be opposite to the connecting shaft 130, so that the connecting shaft 130 is inserted into the plate through hole 122 under the action of the restoring force of the spring 140.

[0053] like Figure 3 As shown, the quick-installation structure 100 further includes:

[0054] A connecting seat 160 is disposed inside the support member 200. A connecting shaft 130 passes through the connecting seat 160. A spring 140, sleeved outside the connecting shaft 130, is located inside the connecting seat 160. The spring 140 abuts against the step 131 on the outer wall of the connecting shaft 130 and the top plate 161 of the connecting seat 160.

[0055] The connecting seat 160 includes a top plate 161 and a side plate 162, which are integrally connected. The end of the side plate 162 away from the top plate 161 is connected to the inner side of the support member 200, and the two can be fixed by welding. The spring 140 is sleeved on the outer wall of the connecting shaft 130 and located inside the connecting seat 160. The spring 140 abuts between the step 131 on the outer wall of the connecting shaft 130 and the top plate 161 of the connecting seat 160, providing a restoring force for the movement of the connecting shaft 130.

[0056] When the mounting component 300 is disassembled relative to the support component 200, the connecting shaft 130 can be moved out of the plate through hole 122 so that the plate 120 is disengaged from the insertion of the connecting shaft 130. Then, the mounting component 300 is moved upward around the front pin 111 so that the pin 110 is moved out of the slide groove 121, thereby realizing the disassembly of the mounting component 300 relative to the support component 200.

[0057] like Figure 3 As shown, the quick-installation structure 100 further includes:

[0058] Pull ring 150, the pull ring 150 is connected to the top of the connecting shaft 130, and the bottom of the connecting shaft 130 is used to pass through the support member 200 and the plate 120.

[0059] The installer can pull the pull ring 150 to remove the connecting shaft 130 from the plate through hole 122.

[0060] In summary, the support member 200 is provided with a pin 110, and the mounting member 300 is provided with a plate 120. Moving the mounting member 300 with the plate 120 aligns the groove 121 on the plate 120 with the pin 110. Then, the mounting member 300 is moved further to allow the pin 110 to slide into the groove 121. Finally, the connecting shaft 130 is inserted into the plate 120 and the support member 200 to complete the installation of the mounting member 300 on the support member 200. Disconnecting the connecting shaft 130 from the plate 120 and the support member 200, and then moving the mounting member 300, allows the pin 110 to move out of the groove 121, completing the disassembly of the mounting member 300 relative to the support member 200. This method is convenient and effectively improves installation and disassembly efficiency.

[0061] Second Embodiment

[0062] like Figure 4 and Figure 5 As shown, the bed includes a quick-release structure 100 according to the first embodiment, and the mounting member 300 is configured as a bed board assembly 310. There are two quick-release structures 100, located on opposite sides of the bed board assembly 310, which improves the stability of the bed board assembly 310 when installed on the support member 200.

[0063] The bed board assembly 310 includes a bed board support 311 and a bed board 312. Two boards 120 are respectively provided on both sides of the inner end of the bed board support 311. Similarly, two sets of pins 110 are respectively provided on both sides of the support member 200, wherein the number of pins 110 in each set is equal to the number of sliding grooves 121 on the same side of the board 120.

[0064] The support member 200 can be a bed frame or a lifting base assembly. The outer end of the bed board support 311 corresponds to the direction of the patient's feet.

[0065] The installation steps are as follows:

[0066] The two sides of the inner end of the bed board bracket 311 are respectively aligned with the pins 110 on both sides of the support member 200. The bed board bracket 311 is moved so that the pins 110 slide into the grooves 121 of the same side of the plate 120. Then, the plate 120 and the support member 200 are respectively inserted by the connecting shaft 130.

[0067] The bed board bracket 311 can be installed on the support member 200 first, and then the bed board 312 can be installed on the bed board bracket 311. Alternatively, the bed board 312 and the bed board bracket 311 can be installed together first, and then the whole assembly can be installed on the support member 200.

[0068] like Figure 4 As shown, the bed board support 311 includes a bed board frame 311a, a bed board drive component 311b, and a bed board connecting rod 311c. The two sides of the inner end of the bed board frame 311a are respectively connected to the board body 120. The bed board drive component 311b and the bed board connecting rod 311c are respectively rotatably connected to the bed board frame 311a. The bed board drive component 311b can be a cylinder. The bed board drive component 311b pushes and pulls the bed board connecting rod 311c, so that the bed board connecting rod 311c rotates around the rotation point between the bed board connecting rod 311c and the bed board frame 311a, thereby driving the bed board 312 on the bed board connecting rod 311c to rotate.

[0069] Furthermore, the bed board 312 can abut against the bed board connecting rod 311c, that is, the bed board 312 slides relative to the bed board connecting rod 311c, and the inner end of the bed board 312 is rotatably connected to the support member 200. Under the drive of the bed board driving member 311b, the bed board 312 can rotate around its inner end.

[0070] Third Embodiment

[0071] like Figure 4 and Figure 5 As shown, the bed includes a quick-release structure 100 according to the first embodiment, and the mounting member 300 is configured as a bed back assembly 320.

[0072] The headboard assembly 320 includes a headboard support 321 and a backboard 322. Two plates 120 are respectively provided on both sides of the inner end of the headboard support 321, and two sets of pins 110 are respectively provided on both sides of the support member 200, wherein the number of pins 110 in each set is equal to the number of grooves 121 on the same side of the plate 120.

[0073] The outer end of the headboard support 321 corresponds to the direction of the patient's head. Similarly, the headboard support 321 includes a headboard frame 321a, a headboard drive component 321b, and a headboard connecting rod 321c. The inner end of the back panel 322 is rotatably connected to the headboard frame 321a, and the back panel 322 abuts against the headboard connecting rod 321c. Under the pushing and pulling action of the headboard drive component 321b, the headboard connecting rod 321c rotates around its rotation point with the headboard support 321, causing the back panel 322 to rotate around its inner end. The installation steps of the headboard assembly 320 are the same as those of the bed board assembly 310 and will not be repeated here.

[0074] Fourth embodiment

[0075] like Figure 4 and Figure 5As shown, the bed includes a quick-assembly structure 100 according to the first embodiment, and the support member 200 is configured as a lifting base assembly 210.

[0076] The lifting base assembly 210 includes a lifting upper support 211 and a lifting power component 213. The lifting power component 213 is rotatably connected to the bed frame and drives the lifting upper support 211 to move up and down.

[0077] The lifting power component 213 can be a cylinder or a motor, for example, the cylinder is mounted on the bed frame, and the output shaft of the cylinder is connected to the lifting upper support 211. The lifting upper support 211 is moved up and down by pushing and pulling the cylinder. Of course, a linkage assembly is provided between the lifting upper support 211 and the bed frame. The cylinder pushes and pulls the linkage assembly to realize the up and down movement of the lifting upper support 211. The structure of the linkage assembly is diverse and will not be described in detail here.

[0078] The pin 110 of the quick-release structure 100 is fixed on the lifting upper bracket 211. That is, the inner end of the bed board assembly 310 and the inner end of the bed back assembly 320 are respectively installed on the lifting upper bracket 211 using the quick-release structure 100. The inner end of the bed board 312 is rotatably connected to the lifting upper bracket 211. Therefore, the bed board assembly 310 and the bed back assembly 320 can rise and fall with the up and down movement of the lifting upper bracket 211.

[0079] The lifting base assembly 210 also includes a lower lifting bracket 212, which is mounted on the bed frame. The linkage assembly can be connected between the lower lifting bracket 212 and the upper lifting bracket 211. Alternatively, the lower lifting bracket 212 can be part of the bed frame.

[0080] The embodiments described above are only used to illustrate the technical ideas and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. The scope of patent application of this utility model should not be limited by these embodiments. That is, any equivalent changes or modifications made in accordance with the spirit disclosed in this utility model still fall within the patent scope of this utility model.
