[0054] The following refers to Figures 1 to 6 The seat frame mechanism according to the embodiment of the utility model is described.

[0055] As Figure 1 The seat frame mechanism according to the embodiment of the utility model includes a middle frame assembly 100 and a support frame assembly, and the two sides of the middle frame assembly 100 are respectively provided with side connecting parts 110, and the side connecting parts 110 are provided with through holes 101;

[0057] The end of the plug-in part 210 can pass through the side connecting part 110 from top to bottom and form a supporting leg structure, or the end of the plug-in part 210 can pass through the side connecting part 110 from top to bottom and be detachably connected with the supporting leg 220;

[0058] A positioning structure is arranged between the plug-in part 210 and the side connecting part 110, and the positioning structure is provided with an unlocked state and a locked state;

[0059] When the positioning structure is in the unlocked state, the plug-in part 210 can be pulled out of the side connecting part 110; when the positioning structure is in the locked state, the positioning structure can position the relative sliding position of the plug-in part 210 and the side connecting part 110, and the positioning structure can limit the relative rotation range of the plug-in part 210 and the side connecting part 110.

[0060] So that the side support 200 can be rotated to a folding state relative to the middle frame assembly 100, reducing the folding and storage volume of the seat frame mechanism, and after the positioning structure is released, the plug-in part 210 can be pulled out of the side connecting part 110, and the side support 200 can be separated from the middle frame assembly 100, so that the seat frame mechanism has a smaller volume after disassembly, facilitating logistics transportation and reducing the transportation cost of the product.

[0061] Specifically, the seat frame mechanism can be used on a toilet chair, a shower chair and the like, and is generally folded and stored when not in use, such as Figure 4 Or Figure 5As shown, by the above structure, the seat frame mechanism in use can be folded to a storage state, and the storage area is small, when the seat frame mechanism is shipped or needs to be stored for a long time, the positioning structure can be removed, the plug-in part 210 is pulled out from the side connecting part 110, and the side support 200 is separated from the middle frame assembly 100, as shown. Figure 6 As shown, so that the seat frame mechanism has a small volume after being disassembled, and is convenient for transportation or long-term storage, and when use is needed, the plug-in part 210 is inserted into the side connecting part 110.

[0062] In some embodiments of the utility model, the end of the plug-in part 210 can pass through the side connecting part 110 from top to bottom, so that the end of the plug-in part 210 can be used as a supporting leg of the seat frame mechanism or can be connected with the supporting leg, that is, the seat frame mechanism is directly supported by the side support 200, and the cooperation of the middle frame assembly 100 is not needed, so that the stability of the seat frame mechanism in use can be improved.

[0063] In some embodiments of the utility model, the positioning structure can limit the relative rotation range of the plug-in part 210 and the side connecting part 110, and the side support 200 can be limited in the rotating opening position and the rotating folding position, so that the unfolding and folding requirements of the side support 200 can be met.

[0064] As shown, Figure 3 In some embodiments of the utility model, the side connecting part 110 is a pipe, and a through hole 101 is arranged in the pipe to cooperate with the plug-in part 210.

[0065] Of course, in the specific implementation process, the side connecting part 110 can also be other components, for example, the middle frame assembly 100 is arranged as an integral plate, and the side connecting part 110 is a side part of the integral plate, and the through hole 101 is arranged, so that the installation requirements of the side support 200 can also be met.

[0066] As shown, Figure 3 In some embodiments of the utility model, the plug-in part 210 is a pipe corresponding to the through hole 101, and the plug-in part 210 can meet the requirements of plug-in connection and rotation cooperation with the side connecting part 110.

[0067] Specifically, the side support 200 is an inverted U-shaped pipe, and the side connecting part 110 is located in the part extending downward at the rear of the side support 200.

[0068] Of course, in the specific implementation process, the side connecting part 110 can also be a solid rod or other structure that can cooperate with the through hole 101, which is not described here.

[0069] In some embodiments of the utility model, the positioning structure includes positioning hole 301, rotation limiting sliding groove 302 and positioning piece 310, rotation limiting sliding groove 302 is long slot or arc slot, one of rotation limiting sliding groove 302 and positioning piece 310 is arranged in side connecting part 110, the other is arranged in plug-in part 210, positioning piece 310 is movably arranged in side connecting part 110 or plug-in part 210, when the positioning structure is in the locking state, positioning piece 310 is inserted into positioning hole 301 and rotation limiting sliding groove 302 respectively, to position the relative sliding position of plug-in part 210 and side connecting part 110, and positioning piece 310 cooperates with rotation limiting sliding groove 302 to limit the relative rotation range of plug-in part 210 and side connecting part 110, to meet the rotation folding requirement of side support 200, when the positioning structure is in the unlocking state, positioning piece 310 is separated from positioning hole 301 and / or rotation limiting sliding groove 302, so that positioning piece 310 is not locked between positioning hole 301 and rotation limiting sliding groove 302, so that side connecting part 110 can be pulled out from through hole 101, facilitating the disassembly of side support 200.

[0070] It can be understood that, in some embodiments of the utility model, the positioning structure includes a limiting block arranged on the plug-in part 210, a sliding groove (the cross section is fan-shaped) corresponding to the limiting block and opening upward is arranged on the inner wall of the through hole 101, the relative rotation range of the plug-in part 210 and the side connecting part 110 is limited by the cooperation of the limiting block and the sliding groove, to meet the rotation folding requirement of the side support 200, at the same time, the cooperation of the limiting block and the sliding groove limits the downward sliding of the plug-in part 210 relative to the side connecting part 110, the positioning structure further includes a plug-in pin arranged on the plug-in part 210, when the plug-in part 210 passes through the through hole 101, the plug-in pin is inserted into the end of the plug-in part 210, to limit the upward sliding of the plug-in part 210 relative to the side connecting part 110, to position the relative sliding position of the plug-in part 210 and the side connecting part 110, to realize the installation of the side support 200, when the plug-in pin is pulled out, the positioning structure can be unlocked, the plug-in part 210 can be pulled out from the through hole 101, to meet the disassembly requirement of the side support 200.

[0071] As shown in the figure, Figure 3 In some embodiments of the utility model, the positioning piece 310 is a first ball arranged on the plug-in part 210, the positioning hole 301 is a ball hole arranged on the plug-in part 210 for the first ball to extend out, the rotation limiting sliding groove 302 is an arc slot arranged on the side connecting part 110, when the plug-in part 210 is inserted into the side connecting part 110 and the first ball is clamped into the arc slot, the positioning structure is in the locking state, the arc slot limits the sliding range of the first ball, to limit the rotatable range of the side support 200, to meet the requirements of unfolding and folding, when the first ball is pressed out of the arc slot, the positioning structure is in the unlocking state, the plug-in part 210 can be pulled out, to meet the disassembly requirement of the side support 200.

[0072] Specifically, the first elastic ball is arranged in the plug-in part 210 through an elastic component such as a spring, an elastic sheet or the like, so that the first elastic ball can keep a state of elastically extending out of the ball hole and can be automatically clamped into the arc-shaped slot, and can also be directly withdrawn from the arc-shaped slot when the first elastic ball is pressed.

[0073] It can be understood that in some embodiments of the utility model, the rotating limiting sliding groove 302 can also be arranged in the plug-in part 210, and the positioning hole 301 and the positioning member 310 (such as the first elastic ball) can also be arranged in the side connecting part 110, so that the assembly, folding and disassembly requirements of the side support 200 can also be met.

[0074] As shown in Figure 4 , in some embodiments of the utility model, the rotating limiting sliding grooves 302 of the two side connecting parts 110 extend towards the inner side of the seat frame mechanism, so that the two side supports 200 can rotate around the side connecting parts 110 towards the inner side of the seat frame mechanism (both of the two side supports 200 rotate to the front of the middle frame assembly 100), and the folding requirements of the side support 200 can be met.

[0075] As shown in Figure 5 , in some embodiments of the utility model, among the rotating limiting sliding grooves 302 of the two side connecting parts 110, one rotating limiting sliding groove 302 extends towards the inner side of the seat frame mechanism, and the other rotating limiting sliding groove 302 extends towards the outer side of the seat frame mechanism, so that one side support 200 can rotate around the side connecting part 110 towards the inner side of the seat frame mechanism, and the other side support 200 can rotate around the side connecting part 110 towards the outer side of the seat frame mechanism, that is, when folding, the two side supports 200 rotate in opposite directions (one side support 200 rotates to the front of the middle frame assembly 100, and the other side support 200 rotates to the rear of the middle frame assembly 100), so that the mutual interference of the two side supports 200 can be reduced, and the overall folding volume can be reduced.

[0076] It can be understood that in some embodiments of the utility model, the rotating limiting sliding grooves 302 of the two side connecting parts 110 extend towards the outer side of the seat frame mechanism, so that the two side supports 200 can rotate around the side connecting parts 110 towards the outer side of the seat frame mechanism (both of the two side supports 200 rotate to the rear of the middle frame assembly 100), and the folding requirements of the side support 200 can also be met.

[0077] It should be noted that in the above description, the inner side of the seat frame mechanism refers to the seating or bearing area of the seat frame mechanism, and the outer side of the seat frame mechanism is the opposite.

[0078] As shown in Figure 1 , Figure 2 , Figure 3As shown, in some embodiments of this utility model, the support frame assembly includes a support leg 220, and the end of the insertion part 210 can pass through the side connection part 110 from top to bottom and be detachably connected to the support leg 220 to meet the disassembly requirements at the support leg and facilitate the folding or disassembly of the seat frame mechanism.

[0079] like Figure 1 , Figure 2 , Figure 3 As shown, in some embodiments of this utility model, the end of the plug-in part 210 is provided with a second ball 211, and the support leg 220 is provided with a plug hole 221 for the end of the plug-in part 210 to be inserted. The wall of the plug hole 221 is provided with a plurality of adjustment holes 222 spaced apart along the length direction of the support leg 220. The second ball 211 can be inserted into different adjustment holes 222 to adjust the length of the support leg 220 extending relative to the plug-in part 210. The second ball 211 can be compressed to allow the end of the plug-in part 210 to pass through the through hole 101 from top to bottom, thereby satisfying the requirements for the fitting and installation of the plug-in part 210 and the side connection part 110, as well as the requirements for the detachable installation and adjustable length of the support leg.

[0080] It is understood that in some embodiments of this utility model, the wall of the insertion hole 221 is provided with a single ball bearing hole spaced apart along the length direction of the support leg 220, and the support leg can be detached and installed by the cooperation of the second ball bearing 211 with the ball bearing hole.

[0081] In some embodiments of this utility model, the second ball 211 is configured not to be stuck in the rotation limiting slide 302, so that when the second ball 211 passes through the area of ​​the rotation limiting slide 302, it will not be stuck in the rotation limiting slide 302. That is, the second ball 211 can pass directly through the rotation limiting slide 302, which facilitates the installation of the plug part 210.

[0082] In some embodiments of this utility model, the rotation limiting groove 302 is adapted to the first ball, and the outer diameter of the second ball 211 is larger than the outer diameter of the first ball, so that the second ball 211 will not get stuck in the rotation limiting groove 302.

[0083] Specifically, both the first and second marbles 211 are marbles with spherical ends. The rotation limiting groove 302 is configured to correspond to the outer diameter of the first marble (or be slightly larger than the outer diameter of the first marble), so that the first marble can be inserted into the rotation limiting groove 302, and the axial movement after the insertion part 210 and the side connecting part 110 are assembled can be reduced, thereby improving the compactness of the mechanism. The outer diameter of the second marble 211 is configured to be larger than the first marble or larger than the corresponding height of the rotation limiting groove 302, so that when the second marble 211 passes through the area of ​​the rotation limiting groove 302, it will not be inserted into the rotation limiting groove 302, but will pass directly through the rotation limiting groove 302, thereby facilitating the installation of the insertion part 210. The adjustment hole 222 on the support leg 220 is configured to correspond to the second marble 211, thereby satisfying the installation and adjustment functions of the support leg 220.

[0084] In some embodiments of this utility model, both the first and second marbles 211 are marbles with spherical ends. The rotation limiting groove 302 is configured to correspond to the outer diameter of the first marble, and the outer diameter of the second marble 211 is configured to be greater than that of the first marble or greater than the corresponding height of the rotation limiting groove 302. This ensures that when the second marble 211 passes through the area of ​​the rotation limiting groove 302, it cannot completely enter the rotation limiting groove 302, and only part of the spherical front end enters the rotation limiting groove 302. This prevents the second marble 211 from forming a jamming relationship with the rotation limiting groove 302. When an upward force is applied to the insertion part 210, the second marble 211 will automatically retract due to the guiding effect of the spherical surface, thus smoothly passing through the rotation limiting groove 302.

[0085] Of course, in the specific implementation process, the first marble and the second marble 211 can also be configured with other structures, such as the first marble and the second marble 211 being cylindrical marbles. The above function can also be achieved by setting the outer diameter of the second marble 211 to be larger than the outer diameter of the first marble.

[0086] It is understood that in some embodiments of this utility model, the end of the plug-in part 210 and the support leg 220 can also be connected by other detachable mechanisms. For example, the plug-in part 210 and the support leg 220 can be configured as a telescopic sleeve structure and equipped with a clamping mechanism. By tightening or loosening the clamping mechanism, the detachable and telescopic connection requirements of the plug-in part 210 and the support leg 220 can be met. Alternatively, a snap-fit ​​mechanism can be provided between the plug-in part 210 and the support leg 220. The detachable connection between the plug-in part 210 and the support leg 220 can also be achieved through the snap-fit ​​mechanism.

[0087] like Figure 3 As shown, in some embodiments of this utility model, the upper end of the side connecting part 110 is provided with a guide structure 111 for guiding and compressing the first ball and / or the second ball 211 into the interior of the insertion part 210, thereby facilitating the insertion and installation of the insertion part 210 and the side connecting part 110.

[0088] Specifically, when the plug-in part 210 is plugged with the side connecting part 110, the first and / or second elastic balls 211 are moved to the upper end of the side connecting part 110, the guide structure 111 pushes the first and / or second elastic balls 211 to move and compress to the inside of the plug-in part 210, so that the first and / or second elastic balls 211 can directly enter the through hole 101, facilitating the plug-in installation of the plug-in part 210 and the side connecting part 110.
