[0036] The utility model provides a hidden leg board switch 100, which aims to make the overall structure of the leg board locking switch more simple and optimize the appearance design of the operating table.

[0037] In the embodiment of the present utility model, in combination with reference to Figure 1 , Figure 2 The hidden leg board switch 100 includes a leg board joint 10 and a guide column 20. The leg board joint 10 is provided with a first guide hole 11. One end of the guide column 20 is inserted into the first guide hole 11. A mounting hole 21 is provided on the side of the guide column 20. The guide column 20 is connected to the side plate 60 of the operating bed through the mounting hole 21. The leg board joint 10 protrudes from the side plate 60 of the operating bed, and the guide column 20 is hidden in the side plate 60 of the operating bed.

[0038] It can be understood that the hidden leg board switch 100 is a functional component of the operating bed, which is generally used for the fixed connection between the operating bed and the leg board. The hidden leg board switch 100 is installed on the operating bed by a fixed connection. The utility model divides the hidden leg board switch 100 into a leg board joint 10 and a guide column 20. The leg board joint 10 is used for the coordinated installation with the leg board, and the guide column 20 is used for the fixed connection with the operating bed. The guide column 20 is inserted on the leg board joint 10, so that the two functions of the hidden leg board switch 100, connecting the leg board and installing on the operating bed, are respectively completed by the leg board joint 10 and the guide column 20. By hiding the guide column 20 in the operating bed, the hidden leg board switch 100 only exposes the leg board joint 10 for the installation of the leg board. In this way, the hidden leg board switch 100 can not only ensure the structural function of normal use, but also meet the requirements of the hidden leg board switch 100 being small in size and simple in structure.

[0039] In some embodiments, the connection between the guide column 20 and the leg plate joint 10 can be a threaded connection, which does not require the coordination of additional components, and only requires corresponding threads to be set on the guide column 20 and the leg plate joint 10; the guide column 20 and the leg plate joint 10 can also be connected by a pin, by setting corresponding through holes on the guide column 20 and the leg plate joint 10, and installing the pins in the through holes to fix the two, so that the direction of the leg plate joint 10 can be fixed by the set through holes.

[0040] In other embodiments, the leg board connector 10 includes two parts, namely a part for connecting with the guide column 20 and a part for installing with the leg board. The part connected with the guide column 20 can also be hidden in the side panel of the operating bed. In this way, a part of the leg board connector 10 can also be hidden, and only the part for installing with the leg board is exposed, thereby further optimizing the hiding effect of the hidden leg board switch 100.

[0041] Further, see Figures 1 to 4 In one embodiment, the hidden leg board switch 100 further includes a locking assembly 30 , which passes through the operating bed side panel 60 and is inserted into the mounting hole 21 to fix the guide column 20 to the operating bed side panel 60 .

[0042] In this arrangement, the connection between the guide column 20 and the operating bed side panel 60 is completed by the locking assembly 30. The locking assembly 30 passes through the operating bed side panel 60 and is inserted into the mounting hole 21, so that the matching connection relationship between the guide column 20 and the operating bed side panel 60 is relatively simple, and there is no need to set a complicated mounting position on the operating bed.

[0043] In some embodiments, the locking assembly 30 may include a stud, and a thread is set in the mounting hole 21 to cooperate with the stud. After the stud passes through the operating bed side plate 60, it cooperates with the mounting hole 21 thread to fix the guide column 20 on the operating bed side plate 60.

[0044] Further, see Figure 3 , Figure 4 In one embodiment, a protrusion 321 is provided on the outer wall of the locking assembly 30, and a guide groove 211 is provided on the inner wall of the mounting hole 21. One end of the guide groove 211 is connected to the opening of the mounting hole 21, and the protrusion 321 enters the mounting hole 21 through the guide groove 211. The locking assembly 30 is rotated to misalign the protrusion 321 and the guide groove 211 to fix the locking assembly 30 in the mounting hole 21.

[0045] In this way, a guide groove 211 is provided on the inner wall of the mounting hole 21, and a protrusion 321 is provided on the locking assembly 30. Through the cooperation between the protrusion 321 and the guide groove 211, the guide groove 211 guides the protrusion 321 to penetrate into the mounting hole 21, so that the locking assembly 30 can be locked in the guide column 20, thereby completing the connection between the guide column 20 and the side plate 60 of the operating table.

[0046] In some embodiments, the shape of the guide groove 211 can include three sections, the first section is the outermost end of the mounting hole 21 and is straight, the second section is connected to the first section by a corner, so that after the protrusion 321 completes the first section, it is necessary to rotate the locking assembly 30 to send the protrusion 321 into the second section, the third section is the innermost end of the mounting hole 21, the third section can be an annular groove, the third section is connected to the second section, so that after the protrusion 321 completes the second section, it is necessary to rotate the locking assembly 30 again so that the protrusion 321 can enter the annular groove of the third section, so that the protrusion 321 is confined in the annular groove, and the locking assembly 30 cannot be detached from the mounting hole 21 without rotation, thereby completing the locking.

[0047] In other embodiments, the shape of the guide groove 211 can also include more segments, as long as the multiple segments are connected by corners, so that the locking assembly 30 needs to be continuously rotated to send the protrusion 321 to the innermost end of the mounting hole 21. Therefore, the shape of the guide groove 211 is not specifically limited here.

[0048] Further, see Figure 4 In one embodiment, the locking assembly 30 includes an elastic member 31, a spring key 32 and a top shaft 33. The elastic member 31 is located in the mounting hole 21. The outer surface of the spring key 32 is provided with a protrusion 321. One end of the spring key 32 abuts against the elastic member 31, and the top shaft 33 abuts against an end of the spring key 32 away from the elastic member 31.

[0049] With such arrangement, when the locking assembly 30 locks the guide column 20 and the operating bed side plate 60, the elastic member 31 is located at the innermost end of the mounting hole 21, the top shaft 33 is located at the outermost end of the mounting hole 21, and the spring key 32 is located between the top shaft 33 and the elastic member 31. In this way, after the protrusion 321 on the spring key 32 has completed the guide groove 211, the spring key 32 is stabilized at the innermost end of the guide groove 211 by the elastic force of the elastic member 31. When the spring key 32 needs to be removed from the mounting hole 21, the elastic member 31 can provide elastic support for the detachment of the spring key 32, so that the locking assembly 30 is relatively stable when locked and can be easily disassembled.

[0050] In some embodiments, two protrusions 321 on the spring key 32 can be symmetrically provided, and two guide grooves 211 in the mounting hole 21 are correspondingly provided. In this way, when the spring key 32 is acted upon by the elastic force of the elastic member 31, the two symmetrical protrusions 321 abut against the guide grooves 211 to provide a reaction force. Since the protrusions 321 are symmetrically provided, the force state of the spring key 32 is relatively balanced, thereby further making the locking state of the locking assembly 30 more stable.

[0051] In other embodiments, the elastic member 31 may be various types of springs, such as a tension spring, a compression spring, a torsion spring, and the like.

[0052] Further, see Figures 1 to 6 In one embodiment, the leg hidden switch 100 also includes a seat plate joint 40, which is provided with a first through hole 41 and a second through hole 42. The first through hole 41 passes through the seat plate joint 40, and the second through hole 42 is vertically connected to the first through hole 41. The guide column 20 is passed through the first through hole 41, and the locking assembly 30 is inserted into the mounting hole 21 through the second through hole 42.

[0053] In this arrangement, the guide column 20 is passed through the seat plate joint 40 and is indirectly fixed to the operating bed side plate 60 through the seat plate joint 40. Since the guide column 20 is limited by its shape, the guide column 20 is first installed on the seat plate joint 40 and then installed on the operating bed side plate 60 through the seat plate joint 40, so that the installation of the guide column 20 is more stable.

[0054] In some embodiments, the seat plate joint 40 can be shaped like a cube or a cuboid, so that the shape of the seat plate joint 40 can be relatively matched with the shape of the operating bed side plate 60, and the seat plate joint 40 can be more stable and less likely to shake when installed on the operating bed side plate 60.

[0055] Further, see Figure 6 In one embodiment, a limiting step 421 is provided in the second through hole 42 , and the limiting step 421 limits the insertion depth of the locking assembly 30 .

[0056] By such arrangement, the depth of the locking assembly 30 entering the mounting hole 21 is limited by the limiting step 421, that is, the insertion depth of the top shaft 33 is limited, so as to prevent the top shaft 33 from being inserted too deeply, causing the protrusion 321 on the spring key 32 to disengage from the guide groove 211, and then the spring key 32 is stuck in the mounting hole 21, or the locking assembly 30 loses the locking function.

[0057] In some embodiments, by providing corresponding limiting convex strips on the circumference of the top shaft 33 , the limiting convex strips cooperate and abut with the limiting steps 421 , so that the limiting steps 421 have a better effect of limiting the top shaft 33 .

[0058] Further, see Figure 6 In one embodiment, the seat plate joint 40 is provided with a third through hole 43, which is parallel to the first through hole 41 and spaced apart in height; the leg plate joint 10 is provided with a second guide hole 13, which is parallel to the first guide hole 11 and spaced apart in height, and a stabilizing column 50 is inserted into the second guide hole 13, and an end of the stabilizing column 50 away from the leg plate joint 10 is inserted into the third through hole 43.

[0059] In this arrangement, the leg plate joint 10 is also connected to the seat plate joint 40 through the stabilizing column 50. In this way, the leg plate joint 10 is connected to the seat plate joint 40 through the guide column 20 and the stabilizing column 50, so that no relative displacement will occur between the leg plate joint 10 and the seat plate joint 40, and the installation stability of the leg plate joint 10 is stronger.

[0060] In some embodiments, the stabilizing column 50 can be inserted into the second guide hole 13 by interference fit. When the leg plate joint 10 is connected to the seat plate joint 40, the end of the stabilizing column 50 away from the leg plate joint 10 also has an interference fit with the third through hole 43. In this way, the stabilizing column 50 is relatively stable with the leg plate joint 10 and the seat plate joint 40 without misalignment due to gaps.

[0061] Further, see Figure 1 , Figure 2 In one embodiment, a positioning pin 12 is provided on the leg plate joint 10 , and the positioning pin 12 penetrates the leg plate joint 10 and the guide column 20 to fix the position of the guide column 20 .

[0062] With such a configuration, the leg plate joint 10 and the guide column 20 are connected and fixed by the positioning pin 12, which can not only meet the connection strength requirements between the leg plate joint 10 and the guide column 20, but also meet the effect of quickly and conveniently replacing the leg plate joint 10, and facilitate the subsequent upgrade or replacement of the leg plate joint 10.

[0063] In some embodiments, the length of the locating pin 12 is equal to the width of the leg plate joint 10, so that after the locating pin 12 is connected to the leg plate joint 10 and the guide column 20, no extra part will be exposed, and the locating pin 12 just fills the through hole on the leg plate joint 10, which can reduce the volume of the leg plate joint 10 and facilitate the removal of the locating pin 12.

[0064] Further, see Figure 5 In one embodiment, a mounting position 14 is provided at one end of the leg plate joint 10 away from the guide column 20, and the mounting position 14 is fixedly cooperated with the leg plate.

[0065] It can be understood that the mounting position 14 is used for installation connection with the leg board. The mounting position 14 is arranged at one end of the leg board joint 10 away from the guide column 20, so that the mounting position 14 can occupy the available space of the leg board joint 10 as much as possible, making it more convenient to connect the mounting position 14 with the leg board.

[0066] In some embodiments, the mounting position 14 may be provided with two hinge ears, the connecting end of the leg plate is disposed between the two hinge ears, and the leg plate is mounted on the mounting position 14 by means of pins.

[0067] The utility model also proposes an operating bed, which includes a hidden leg board switch 100. The specific structure of the hidden leg board switch 100 refers to the above embodiment. Since the operating bed adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0068] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
