The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

The embodiment of the application provides a supporting device. Referring to fig. 1 to 6, a supporting device 100 provided in an embodiment of the present application may include: a base 110, a locking member 120, a plurality of supporting members 130, and a plurality of first elastic members 140. The base 110 has a plurality of first through holes 111, the locking member 120 has a plurality of flexible sleeves 121, and each of the flexible sleeves 121 has a second through hole 1211. The supporting members 130 are slidably disposed in the first through holes 111, and the supporting members 130 are correspondingly disposed through the second through holes 1211.

In the embodiment of the present application, each of the supporting pieces 130 is slidable between the extended position and the retracted position, and the first elastic elements 140 are configured to apply an elastic force to the supporting pieces 130 away from the retracted position in a one-to-one correspondence. Exemplarily, in an embodiment of the present application, in a case where the support 130 carries the to-be-supported member 200, the support 130 may move toward the retracted position under the gravity of the to-be-supported member 200; after the standby support 200 is removed, the support 130 may be moved to the extended position by the elastic force of the first elastic member 140.

When the locking member 120 is moved to the locking position, the outer wall of each of the supporting members 130 may abut against the wall of the corresponding second through hole 1211. In the embodiment of the present application, the locking member 120 may be moved to the locking position, and the supporting member 130 is limited by the wall of the second through hole 1211 abutting against the outer wall of the supporting member 130, so that the supporting member 130 contacting with the member to be supported 200 is maintained in a state of contacting with the member to be supported 200.

In this way, in the embodiment of the present application, in the case where the support to be supported 200 is required, the support to be supported 200 may be disposed on the support 130, and the support 130 may be moved toward the retracted position by the acting force exerted by the support to be supported 200. Further, the locking member 120 may be moved to the locking position, and the supporting member 130 may be limited by the wall of the second through hole 1211 abutting against the outer wall of the supporting member 130, so that the supporting member 130 contacting with the member to be supported 200 is maintained in a state of contacting with the member to be supported 200. In this way, the supporting device 100 can be used to support various shapes of the supporting members 200, and the versatility of the supporting device 100 can be improved.

It should be noted that, in the embodiment of the present application, since the second through hole 1211 is disposed on the flexible sleeve 121, when the hole wall of the second through hole 1211 abuts against the outer wall of the supporting member 130, the flexible sleeve 121 can be elastically deformed, so that the hole wall of each second through hole 1211 can better abut against the outer wall of each supporting member 130, and the locking member 120 can better limit the position of each supporting member 130.

Referring to fig. 3, in the embodiment of the present application, the locking member 120 is slidably disposed on the base 110, and the locking member 120 can be slidably switched between the unlocking position and the locking position. Exemplarily, referring to fig. 3, in case that the locking member 120 is located at a position such that the axis of the second perforation 1211 coincides with the axis of the support member 130, the locking member 120 may be considered to be located at the unlocked position. In the case where the locking member 120 is located such that the axis of the second through-hole 1211 is offset from the axis of the support member 130 by a preset distance, the locking member 120 may be considered to be located at the locking position. For example, the locking member 120 may be moved to the left side to a position where the outer wall of each of the supporters 130 abuts against the hole wall of the corresponding second through hole 1211, and at this time, the locking member 120 may be considered to be located at the locking position.

In an embodiment of the present application, the supporting device 100 may further include a driver 150, the driver 150 may be in driving connection with the locking member 120, and the driver 150 may be used to drive the locking member 120 to move to the locking position. Illustratively, the actuator 150 may be a linear actuator, for example, the actuator 150 may be a linear motor, an air cylinder, a hydraulic cylinder, or the like, such that the actuator 150 may be used to actuate the locking member 120 to move to the locking position. It should be noted that, in the embodiment of the present application, the supporting device 100 may not include the driver 150. Illustratively, wedges may be used to drive the locking member 120 to the locked position.

In an embodiment of the present application, in case that the supporting device 100 includes the driver 150, the driver 150 may include a threaded rod 151, the threaded rod 151 may be provided with a threaded portion, the base 110 may be provided with a threaded hole, the threaded portion may be threadedly connected with the threaded hole, and the first connection portion of the threaded rod 151 may be drivingly connected with the locking member 120. Thus, in the case of rotating the threaded rod 151, the threaded rod 151 may move in its own axial direction, and the first connection portion of the threaded rod 151 may move in synchronization. Thus, the locking member 120 may be driven to move by driving the threaded rod 151 to move, thereby moving the locking member 120 to the locked position.

In an embodiment of the present application, the driver 150 may further include a turning handle 152, and the turning handle 152 may be drivingly connected with the second connecting portion of the threaded rod 151. When the rotating handle 152 is driven, the rotating handle 152 can drive the threaded rod 151 to rotate relative to the base 110, so that the first connecting portion moves in a direction toward the locking member 120 or in a direction away from the locking member 120. In this way, it is convenient for the operator to drive the threaded rod 151 to rotate by manipulating the rotating handle 152, so that the threaded rod 151 can move along its own axis.

Referring to fig. 3, in an embodiment of the present application, the supporting device 100 may further include a second elastic element 160. The first connecting portion is disposed at an end of the threaded rod 151 close to the locking member 120, the second elastic element 160 is respectively connected to the base 110 and the locking member 120, and the locking member 120 abuts against the first connecting portion under the elastic force of the second elastic element 160. The first connecting portion can drive the locking member 120 to move to the locking position in case the first connecting portion moves in a direction toward the locking member 120, and the second elastic member 160 can drive the locking member 120 to move to the unlocking position in case the first connecting portion moves in a direction away from the locking member 120.

Thus, in embodiments of the present application, the first coupling portion of the threaded rod 151 may urge the locking member 120 to move to the locked position when the threaded rod 151 moves in a direction toward the locking member 120. Illustratively, referring to fig. 3, the first connection portion of the threaded rod 151 may move toward the left side, and the first connection portion of the threaded rod 151 may push the locking member 120 to move toward the left side. Thus, the axis of the second through-hole 1211 and the axis of the support 130 may be displaced, and the outer wall of each support 130 may abut against the hole wall of the corresponding second through-hole 1211, so that the support 130 may be restricted by the locking member 120. Further, after the force applied to the lock member 120 by the threaded rod 151 is removed, the lock member 120 may be moved toward the unlock position by the elastic force of the second elastic member 160.

Referring to fig. 3, in an embodiment of the present application, the locking member 120 may be provided with a first abutting portion 122, and the base 110 may be provided with a second abutting portion 112. In the case where the first connecting portion moves to the target position in the direction away from the locking member 120, the first abutting portion 122 abuts against the second abutting portion 112, and the locking member 120 can be stopped at the unlocking position. The outer wall of each support 130 may be separated from the wall of the corresponding second aperture 1211.

Thus, in the embodiments of the present application, the driver 150 can be utilized to cause the locking member 120 to rest in the locked position. After the driving force applied to the locking member 120 by the driver 150 is removed, the locking member 120 can move in a direction away from the locking position (i.e., in a direction close to the unlocking position) by the elastic force of the second elastic member 160. Further, the locking member 120 can be accurately stopped at the unlocking position by the abutting engagement of the first abutting portion 122 and the second abutting portion 112.

In an embodiment of the present application, in case that the supporting device 100 includes the base 110, the locking member 120, the plurality of supporting members 130, and the plurality of first elastic members 140, the supporting device 100 may further include a second elastic member 160. The second elastic member 160 may be connected to the base 110 and the locking member 120, respectively, and the second elastic member 160 may be capable of applying an elastic force to the locking member 120 away from the locking position. In this way, the second elastic member 160 may be used to apply an elastic force to the locking member 120 to move the locking member 120 from the locking position to the unlocking position.

For example, in the embodiment of the present application, after the driving force applied to the locking member 120 is removed, the locking member 120 may be moved to the unlocking position by the second elastic member 160. In this way, the locking member 120 will not limit the position of the supporting member 130, and the supporting member 130 can be in the extended position by the first elastic member 140. Thus, it is possible to enable each support 130 to be in the extended position without applying an external force to the supporting device 100.

Further, referring to fig. 3, in an embodiment of the present application, in case that the supporting device 100 further includes a second elastic element 160, the locking member 120 may be provided with the first abutting portion 122, and the base 110 may be provided with the second abutting portion 112. In the case where the first connecting portion moves to the target position in the direction away from the locking member 120, the first abutting portion 122 abuts against the second abutting portion 112, and the locking member 120 can be stopped at the unlocking position. The outer wall of each support 130 may be separated from the wall of the corresponding second aperture 1211.

Referring to fig. 3 and 6, in an embodiment of the present application, the base 110 may include a first portion 113 and a second portion 114, the first portion 113 may be provided with a slide groove 1131, the locking member 120 may be slidably provided in the slide groove 1131, and the plurality of first through holes 111 are all provided in the first portion 113. Illustratively, the first portion 113 may be a unitary structure, or the first portion 113 may be a split structure. In the case where the first part 113 is a split type structure, the first part 113 may include a first sub-section and a second sub-section. Referring to fig. 3, the first sub-portion may be an upper portion of the first portion 113, and the second sub-portion may be a lower portion of the first portion 113. The locking member 120 may be interposed between the first sub-portion and the second sub-portion.

In the embodiment of the present application, the first elastic elements 140 are disposed between the supporting members 130 and the second portions 114 in a one-to-one correspondence. In this way, the first elastic element 140 may enable the extended state without the support 130 being subjected to an external force.

Referring to fig. 3, in an embodiment of the present application, an end of each supporting member 130 close to the first elastic element 140 may be provided with a stopping portion 131, the stopping portion 131 may be disposed on a side of the first portion 113 close to the second portion 114, and the stopping portion 131 may abut against an aperture portion of the corresponding first through hole 111 when the supporting member 130 is moved to the extended position. Note that the aperture portion of the first through hole 111 may refer to an edge portion of the first portion 113 located at the outer periphery of the first through hole 111. In this way, the support 130 can be extended to the extended position by the elastic force of the first elastic element 140 by the abutting portion 131 abutting against the opening of the first through hole 111.

Referring to fig. 5 and 6, in an embodiment of the present application, the base 110 may further include a third portion 115, the third portion 115 may be connected with the first portion 113, and the third portion 115 may be disposed opposite to the locking member 120. In case the support device 100 comprises an actuator 150 with a threaded rod 151, the threaded rod 151 may be threadedly connected with the third portion 115.

Referring to fig. 5 and 6, in an embodiment of the present application, the base 110 may further include a fourth portion 116. The fourth portion 116 may be connected to the first portion 113, and the second elastic member 160 may be disposed between the fourth portion 116 and the locking member 120.

It should be noted that, in the embodiment of the present application, the convenience of mounting and dismounting the supporting device 100 may be improved by making the base 110 a split structure. It should also be noted that in the embodiment of the present application, the base 110 may also be of a one-piece construction. Alternatively, in the case that the base 110 has a split structure, the base 110 may be separated into other components, which will not be described herein.

In the embodiment of the present application, the second portion 114 may be respectively provided with third through holes at positions opposite to the first elastic elements 140. The second portion 114 may comprise a plurality of blocking members, which are detachably connected to the third through holes in a one-to-one correspondence, and the first elastic elements 140 can pass through the third through holes in a case where the third through holes are not blocked by the blocking members.

With reference to fig. 3, a third through hole may be formed in the second portion 114, so that when the first elastic element 140 needs to be installed or replaced, the blocking member may be removed, and the third through hole may be in an open state, so that the first elastic element 140 may be taken out through the third through hole, or the first elastic element 140 may be disposed between the supporting member 130 and the second portion 114. After the first elastic element 140 is disposed between the support 130 and the second portion 114, the third through hole may be blocked by a blocking member, so that the first elastic element 140 may be prevented from falling out through the third through hole.

For example, the blocking member may be screwed to the second portion 114, i.e. the blocking member may be detachably connected to the third perforation by screwing to the second portion 114. The shutoff piece can the joint in third perforation department, and like this, the shutoff piece can be connected with the shutoff of third perforation detachably through the mode of joint in third perforation department.

In an embodiment of the present application, an end of each support 130 away from the first elastic element 140 may be provided with a support portion 132 for supporting the to-be-supported member 200, and each support portion 132 may be exposed to an outer surface of the support device 100 in a case where each support 130 is moved to the extended position. Exemplarily, in an embodiment of the present application, the supporting portion 132 may be a hemispherical surface. In this way, it is convenient to provide a supporting force to the to-be-supported member 200 using the supporting member 130.

In the embodiment of the present application, the locking member 120 may be provided with a plurality of fourth through holes, and the flexible sleeves 121 may be inserted into the fourth through holes in a one-to-one correspondence. The flexible sleeve 121 may be a silicone sleeve. Illustratively, in the embodiment of the present application, the flexible sheath 121 may be embedded in the fourth through hole by means of adhesion. It should be noted that the flexible sleeve 121 may also have other configurations than a silicone sleeve, and only a certain deformation capability is required for the flexible sleeve 121, so that the hole wall of the second through hole 1211 of each flexible sleeve 121 can abut against the outer wall of the supporting member 130 when the locking member 120 is in the locked state.

Hereinafter, referring to fig. 1 and 4, a method of using the supporting device 100 will be briefly described by taking as an example the supporting device 100 including the driver 150 provided with the threaded rod 151 and the turning handle 152.
