Abstract

The support comprises a base, a supporting rod and a limiting mechanism, the supporting rod and the base are rotatably connected and can rotate to a first position and a second position, when the supporting rod is located at the first position, the support is in a folded state, and when the supporting rod is located at the second position, the support is in an unfolded state; the limiting mechanism is arranged between the base and the supporting rod, the limiting mechanism is suitable for generating resistance to the supporting rod when the supporting rod rotates from the first position to the second position, the supporting rod can be prevented from rotating from the first position to the second position under the action of the resistance, and therefore the supporting rod is kept at the first position, and the folding state of the support is maintained. Only when the supporting rod bears external force and the external force is larger than the borne resistance, for example, under the condition of manual operation, the supporting rod can overcome the hindering effect of the resistance to successfully rotate to the second position, and therefore the support can be prevented from being switched from the folded state to the unfolded state under the accidental condition.

Description

Technical Field

[0002] Some clothes drying racks are fixed to the wall for horizontal support. When these racks are not needed, they take up space. Foldable racks have emerged in related technologies. Foldable racks have a folded state and an unfolded state. They can be switched to the unfolded state when in use and to the folded state when not in use to reduce space occupation. However, this type of rack is prone to accidentally switching from the folded state to the unfolded state. Utility Model Content

[0011] And / or, the first mating member and the second mating member are adapted to first abut and then offset when the strut rotates from the second position to the first position.

[0012] In some embodiments of this application, the first mating member has a first latching protrusion, the second mating member has a second latching protrusion, and the first mating member and the second mating member are adapted to abut against each other through the first latching protrusion and the second latching protrusion;

[0013] The first or second protrusion has hollowed-out grooves on its opposite sides to accommodate elastic deformation.

[0014] In some embodiments of this application, the first mating member and the base are plugged into each other.

[0015] In some embodiments of this application, the second mating member and the support rod are plugged into each other.

[0016] In some embodiments of this application, the first mating member is provided with a first step, and the first mating member is adapted to abut against the periphery of the insertion port of the base by means of the first step when the base is inserted.

[0017] In some embodiments of this application, the second mating member is provided with a second step, and the second mating member is adapted to abut against the periphery of the insertion port of the support rod by means of the second step when the support rod is inserted.

[0018] In some embodiments of this application, at least a portion of one of the first mating member and the second mating member is embedded inside the other.

[0019] In some embodiments of this application, the first mating member is inserted into the base along a first direction, and the second mating member is adapted to exert a force on the first mating member along the first direction when it abuts against the first mating member.

[0020] In some embodiments of this application, the second mating member is inserted into the support rod in a second direction, and the first mating member is adapted to exert a force on the second mating member in the second direction when it abuts against the second mating member.

[0021] In some embodiments of this application, the strut and the base are rotatably connected by a first fastener, which also passes through the first mating member and the second mating member.

[0022] In some embodiments of this application, the stent further includes:

[0023] A crossbar passes through the support rod and intersects with the support rod;

[0024] A third mating component is disposed between the crossbar and the support rod; and

[0025] The second fastener is adapted to connect with the strut and abut against the third mating member so that the third mating member abuts against the crossbar.

[0026] In some embodiments of this application, the third mating member is provided with a movable abutment portion, and the second fastener is adapted to support the abutment portion so that the abutment portion abuts against the crossbar.

[0033] In this application's technical solution, the support rod and base are rotatably connected, allowing the bracket to switch between folded and unfolded states. When the bracket is folded, it reduces space occupation; when unfolded, it supports or suspends items. By setting a limiting mechanism between the support rod and the base, the limiting mechanism generates resistance to the support rod when it rotates from the first position to the second position. This resistance prevents the support rod from rotating from the first position to the second position, thus keeping the support rod in the first position and maintaining the bracket's folded state. Only when the support rod is subjected to an external force greater than the resistance, such as under manual operation, can the support rod overcome the resistance and successfully rotate to the second position. This prevents the bracket from switching from the folded state to the unfolded state unexpectedly.

[0034] Other advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description or may be learned by practice of this application. Attached Figure Description

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features.

[0056] This application discloses a stent, combined with Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the support includes a base 1000 and a support rod 2000. The support rod 2000 and the base 1000 are rotatably connected and can rotate to a first position and a second position. When the support rod 2000 is in the first position, the support is in a folded state. When the support rod 2000 is in the second position, the support is in an unfolded state. A limiting mechanism 3000 is disposed between the base 1000 and the support rod 2000. The limiting mechanism 3000 is adapted to generate resistance to the support rod 2000 when the support rod 2000 rotates from the first position to the second position.

[0057] The support rod 2000 and the base 1000 are rotatably connected, allowing the bracket to switch between a folded state and an unfolded state. When the bracket is folded, it reduces space occupation; when unfolded, it supports or suspends items. A limiting mechanism 3000 is provided between the support rod 2000 and the base 1000. This limiting mechanism 3000 generates resistance to the support rod 2000 when it rotates from the first position to the second position. This resistance prevents the support rod 2000 from rotating from the first position to the second position, thus keeping it in the first position and maintaining the folded state of the bracket. Only when the support rod 2000 is subjected to an external force greater than the resistance, such as under manual operation, can the support rod 2000 overcome the resistance and successfully rotate to the second position. This prevents the bracket from accidentally switching from the folded state to the unfolded state.

[0058] Specifically, the base 1000 serves as the supporting foundation for the bracket, connecting with other components to provide support. The base 1000 can be made of metal, plastic, or other materials, and its shape and structure can be varied, tailored to specific needs. During bracket installation, the bracket is completed by fixing the base 1000. For example, if the base 1000 needs to be mounted on a wall, the bracket can be installed by connecting the base 1000 to the wall.

[0059] The support rod 2000 and the base 1000 are rotatably connected. This rotatability can be achieved in several ways, such as via a pivot, a hinge, or other methods. Through this rotatable connection, the support rod 2000 can change position relative to the base 1000, specifically rotating to a first position and a second position. When the support is not needed, the support rod 2000 can be rotated to the first position, folding the support and reducing its space-consuming nature. When the support is needed, the support rod 2000 can be rotated to the second position, unfolding the support to support or suspend items.

[0060] For example, the base 1000 is fixed to the wall, and the support rod 2000 is rotatably connected to the base 1000. When the support rod 2000 is in the first position, it is vertical; when it is in the second position, it is horizontal. The support rod 2000 can rotate from bottom to top to the first position, where it is vertical and close to the wall, allowing the bracket to be in a folded state, reducing space occupation. The support rod 2000 can rotate from top to bottom to the second position, where it is horizontal, allowing the bracket to be in an unfolded state, supporting or suspending objects.

[0061] It is understandable that when the bracket is in a folded state, it is undesirable for the bracket to switch from a folded state to an unfolded state without human intent. In particular, when the bracket is installed on a wall, it may accidentally switch from a folded state to an unfolded state under the influence of gravity or other factors, which is something that users do not want to happen. Therefore, this embodiment uses a limiting mechanism 3000 to prevent the bracket from accidentally switching from a folded state to an unfolded state.

[0062] A limiting mechanism 3000 is disposed between the support rod 2000 and the base 1000. The limiting mechanism 3000 is used to generate resistance to the support rod 2000 when it rotates from the first position to the second position. The limiting mechanism 3000 generates resistance to the support rod 2000, thereby preventing the support rod 2000 from rotating to the second position. In other words, assuming that the bracket is in the folded state, if the support rod 2000 wants to rotate from the first position to the second position (various unexpected situations can cause the support rod 2000 to want to rotate from the first position to the second position, such as the user accidentally touching the support rod 2000, the support rod 2000 being affected by wind, or the effect of gravity, etc.), it will be subject to the resistance generated by the limiting mechanism 3000. The resistance prevents the support rod 2000 from continuing to rotate to the second position, thus keeping the support rod 2000 in the first position, that is, maintaining the folded state of the bracket. When the support needs to be switched from the folded state to the unfolded state, the external force applied to the support rod 2000 needs to be greater than the resistance (such as the external force applied by the user). This allows the support rod 2000 to overcome the resistance and rotate from the first position to the second position, thereby switching the support from the folded state to the unfolded state. The limiting mechanism 3000 effectively prevents the support from switching from the folded state to the unfolded state unexpectedly.

[0063] Combination Figures 4 to 10 As shown, in some embodiments, the limiting mechanism 3000 includes a first mating member 3100 and a second mating member 3200. The first mating member 3100 is disposed on the base 1000, and the second mating member 3200 is disposed on the support rod 2000. The second mating member 3200 can rotate with the support rod 2000. The first mating member 3100 and the second mating member 3200 are adapted to abut against the support rod 2000 to generate resistance to the support rod 2000 when the support rod 2000 rotates from the first position to the second position.

[0064] The first mating component 3100 is disposed on the base 1000, meaning the first mating component 3100 is fixed to the base 1000. There are various ways to fix the first mating component 3100 to the base 1000, such as screw connection, welding, clamping, etc. The second mating component 3200 is disposed on the support rod 2000, meaning the second mating component 3200 is fixed to the support rod 2000. There are also various ways to fix the second mating component 3200 to the support rod 2000, such as screw connection, welding, clamping, etc. Because the second mating component 3200 is disposed on the support rod 2000, and because the support rod 2000 can rotate relative to the base 1000, the rotation of the support rod 2000 can drive the second mating component 3200 to rotate accordingly.

[0065] After the bracket is assembled, the first mating part 3100 and the second mating part 3200 need to cooperate with each other. The first mating part 3100 is located on the rotation path of the second mating part 3200. The cooperation between the first mating part 3100 and the second mating part 3200 generates resistance to the support rod 2000.

[0066] For example, when the support rod 2000 is to rotate from the first position to the second position, the second mating part 3200 will also rotate with the support rod 2000. The first mating part 3100 is located on the rotation path of the second mating part 3200, thus causing the second mating part 3200 and the first mating part 3100 to abut against each other. Since the first mating part 3100 is fixed to the base 1000, the abutment of the first mating part 3100 against the second mating part 3200 generates resistance. This resistance is transmitted to the support rod 2000 through the second mating part 3200, thereby preventing the support rod 2000 from rotating towards the second position and keeping the support rod 2000 in the first position. When it is necessary to switch the bracket from the folded state to the unfolded state, the user can apply force to the support rod 2000. The force applied by the user is greater than the resistance generated by the abutment of the first mating part 3100 and the second mating part 3200, thus overcoming the resistance and allowing the support rod 2000 to rotate from the first position to the second position, thereby switching the bracket from the folded state to the unfolded state.

[0067] Optionally, in some embodiments, at least one of the first mating member 3100 and the second mating member 3200 is adapted to elastically deform when the first mating member 3100 and the second mating member 3200 abut. This can be either the first mating member 3100 elastically deforming when the first mating member 3100 and the second mating member 3200 abut, or the second mating member 3200 elastically deforming when the first mating member 3100 and the second mating member 3200 abut, or both the first mating member 3100 and the second mating member 3200 elastically deforming when they abut.

[0068] Because the support rod 2000 is held in the first position by the resistance generated by the contact between the first mating part 3100 and the second mating part 3200 when it wants to rotate from the first position to the second position, and because it can overcome the resistance when the external force on the support rod 2000 is greater than the resistance, it can rotate from the first position to the second position. Through the elastic deformation of at least one of the first mating part 3100 and the second mating part 3200 when they contact each other, the resistance is generated more effectively and the support rod 2000 can overcome the resistance more easily when it is subjected to a greater external force. This makes the user experience of switching between the folded and unfolded states of the bracket better.

[0069] Specifically, when the support rod 2000 is to rotate from the first position to the second position, the first mating part 3100 and the second mating part 3200 abut against each other, generating resistance to the support rod 2000. The generation of resistance keeps the support rod 2000 in the first position. When the support rod 2000 is subjected to an external force, such as an external force applied by the user, the external force on the support rod 2000 is greater and it rotates, forcing at least one of the first mating part 3100 and the second mating part 3200 to elastically deform, overcoming the resistance, so that the support rod 2000 can rotate from the first position to the second position.

[0070] Optionally, in some embodiments, the first mating member 3100 and the second mating member 3200 are adapted to first abut and then misalign when the support rod 2000 rotates from the first position to the second position. Misalignment means that the abutting portions of the first mating member 3100 and the second mating member 3200 are misaligned. Since at least one of the first mating member 3100 and the second mating member 3200 is adapted to elastically deform when the first mating member 3100 and the second mating member 3200 abut each other, if either the first mating member 3100 or the second mating member 3200 is in an elastically deformed state for a long time when the support rod 2000 is in the first position or the second position, it will cause the elastically deformed one of the first mating member 3100 and the second mating member 3200 to age prematurely, making it difficult to reset the elastic deformation and affecting the subsequent use of the support.

[0071] Therefore, in this embodiment, the first mating member 3100 and the second mating member 3200 are adapted to first abut and then misalign when the support rod 2000 rotates from the first position to the second position. For example, in combination Figure 5 , Figure 8 , Figure 12 and Figure 13As shown, the first mating member 3100 has a first latching protrusion 3110, and the second mating member 3200 has a second latching protrusion 3210. The first mating member 3100 and the second mating member 3200 are adapted to abut against each other through the first latching protrusion 3110 and the second latching protrusion 3210 to generate resistance against the support rod 2000. At least one of the first latching protrusion 3110 and the second latching protrusion 3210 is adapted to elastic deformation. Taking the first latching protrusion 3110 being adapted to elastic deformation as an example, the first latching protrusion 3110 is part of the first mating member 3100, and the elastic deformation of the first latching protrusion 3110 does not affect the connection and fixation between the remaining part of the first mating member 3100 and the base 1000. In this embodiment, when the support rod 2000 is about to rotate from the first position to the second position, the first locking protrusion 3110 and the second locking protrusion 3210 abut against each other, thereby generating resistance to the support rod 2000. The generation of resistance keeps the support rod 2000 in the first position. When the support rod 2000 is subjected to an external force, such as the external force applied by the user, which is greater than the resistance it receives, and continues to rotate, the first locking protrusion 3110 is forced to elastically deform to avoid the second locking protrusion 3210 and overcome the resistance. As the support rod 2000 rotates to the second position, the second locking protrusion 3210 passes over the first locking protrusion 3110 and is misaligned with each other, and the first locking protrusion 3110 elastically deforms and resets.

[0072] Similarly, the first mating part 3100 and the second mating part 3200 are adapted to first abut and then misalign when the strut 2000 rotates from the first position to the second position. For example, in combination Figure 5 , Figure 8 , Figure 12 and Figure 13 As shown, the first mating member 3100 has a first latching protrusion 3110, and the second mating member 3200 has a second latching protrusion 3210. The first mating member 3100 and the second mating member 3200 are adapted to abut against each other through the first latching protrusion 3110 and the second latching protrusion 3210 to generate resistance against the support rod 2000. At least one of the first latching protrusion 3110 and the second latching protrusion 3210 is adapted to elastic deformation. Taking the first latching protrusion 3110 being adapted to elastic deformation as an example, the first latching protrusion 3110 is part of the first mating member 3100, and the elastic deformation of the first latching protrusion 3110 does not affect the connection and fixation between the remaining part of the first mating member 3100 and the base 1000. In this embodiment, when the first latching protrusion 3110 and the support rod 2000 are to rotate from the second position to the first position, the first latching protrusion 3110 and the second latching protrusion 3210 abut against each other, thereby generating resistance to the support rod 2000. When the support rod 2000 is subjected to an external force, such as the external force applied by the user, which is greater than the resistance it receives, and continues to rotate, the first latching protrusion 3110 is forced to elastically deform to avoid the second latching protrusion 3210. In this way, the resistance is overcome. As the support rod 2000 rotates to the first position, the second latching protrusion 3210 passes over the first latching protrusion 3110 and is misaligned with each other. The first latching protrusion 3110 elastically deforms and resets.

[0073] See Figures 1 to 10 The orientation shown provides further explanation of the support structure.

[0074] The bracket includes a base 1000, a support rod 2000, a limiting mechanism 3000, and a crossbar 4000. There are two bases 1000, which are arranged at a certain distance from each other and located on the same horizontal line. The bases 1000 are connected and fixed to the wall. There are two support rods 2000, which correspond one-to-one with the two bases 1000. One end of one support rod 2000 is rotatably connected to one base 1000, and one end of the other support rod 2000 is rotatably connected to the other base 1000. The crossbar 4000 is connected to the other ends of the two support rods 2000. A limiting mechanism 3000 is provided between the bases 1000 and the support rods 2000. When the support rod 2000 is in the first position, it is set vertically, and the support rod 2000 and the crossbar 4000 are close to the wall. At this time, the bracket is in a folded state, which reduces the space occupied. When the support rod 2000 is in the second position, it is set horizontally, and the crossbar 4000 is relatively far away from the wall. At this time, the bracket is in an unfolded state, which can support objects or allow objects to be suspended. The support rod 2000 can be rotated from the first position to the second position from top to bottom, or from the second position to the first position from bottom to top, thereby switching the folded state and unfolded state of the bracket.

[0075] The limiting mechanism 3000 includes a first mating part 3100 and a second mating part 3200. The first mating part 3100 is disposed on the base 1000, and the second mating part 3200 is disposed on the support rod 2000. The first mating part 3100 has a first locking protrusion 3110 and the first locking protrusion 3110 is adapted to elastic deformation. The second mating part 3200 can rotate with the support rod 2000. The second mating part 3200 has a second locking protrusion 3210, and the first locking protrusion 3110 is located on the rotation path of the second locking protrusion 3210.

[0076] When the support rod 2000 is in the first position and wants to rotate downward toward the second position, the second locking protrusion 3210 abuts against the first locking protrusion 3110 on the rotation path. At this time, the second locking protrusion 3210 is above the first locking protrusion 3110. The first locking protrusion 3110 generates resistance to the second locking protrusion 3210. The resistance is transmitted to the support rod 2000 through the second locking protrusion 3210, thereby preventing the support rod 2000 from rotating downward toward the second position and keeping the support rod 2000 in the first position, thereby maintaining the folded state of the bracket.

[0077] When it is necessary to switch the bracket from the folded state to the unfolded state, the user can apply a downward force to the crossbar 4000 and / or the support rod 2000. The support rod 2000 rotates downward so that the second latch 3210 and the first latch 3110 abut against each other. At this time, the second latch 3210 is located above the first latch 3110. The force applied by the user is greater than the resistance generated by the first latch 3110 on the second latch 3210, so the support rod 2000 continues to rotate downward, forcing the first latch 3110 to elastically deform to avoid the second latch 3210. The second latch 3210 can pass over the first latch 3110 and be located below the first latch 3110. The first latch 3110 elastically deforms and returns to its original position. The support rod 2000 rotates to the second position, and the bracket switches to the unfolded state.

[0078] When it is necessary to switch the bracket from the unfolded state to the folded state, the user can apply an upward force to the crossbar 4000 and / or the support rod 2000. The support rod 2000 rotates upward so that the second latch 3210 and the first latch 3110 abut against each other. At this time, the second latch 3210 is located below the first latch 3110. The force applied by the user is greater than the resistance generated by the first latch 3110 on the second latch 3210, so the support rod 2000 continues to rotate upward, forcing the first latch 3110 to elastically deform to avoid the second latch 3210. The second latch 3210 can pass over the first latch 3110 and be located above the first latch 3110. The first latch 3110 elastically deforms and returns to its original position. The support rod 2000 rotates to the first position, and the bracket switches to the folded state.

[0079] Combination Figure 12 As shown, in some embodiments, the first mating member 3100 has a first latching protrusion 3110, and the second mating member 3200 has a second latching protrusion 3210. The first mating member 3100 and the second mating member 3200 are adapted to abut against each other through the first latching protrusion 3110 and the second latching protrusion 3210 to generate resistance against the strut 2000. At least one of the first latching protrusion 3110 and the second latching protrusion 3210 is adapted to elastically deform when the first latching protrusion 3110 and the second latching protrusion 3210 abut against each other.

[0080] Alternatively, the first latching protrusion 3110 may have hollowed-out grooves 3111 on its opposite sides to accommodate elastic deformation. For example, if the first mating part 3100 is a one-piece molded part, the hollowed-out grooves 3111 on its opposite sides make it easier for the first latching protrusion 3110 and the second latching protrusion 3210 to elastically deform when they abut. The material of the first mating part 3100 can be appropriately slightly harder. The hollowed-out grooves 3111 not only allow for the elastic deformation of the first latching protrusion 3110 but also better generate resistance to the second latching protrusion 3210. In this case, the second mating part 3200 can be a metal part or a hard plastic part.

[0081] Alternatively, the second latching protrusion 3210 may have hollowed-out grooves 3111 on its opposite sides to accommodate elastic deformation. For example, if the second mating part 3200 is a one-piece molded part, the hollowed-out grooves 3111 on its opposite sides make it easier for the second latching protrusion 3210 to elastically deform when it abuts against the first latching protrusion 3110. The material of the second mating part 3200 can be slightly harder. The hollowed-out grooves 3111 allow for both elastic deformation of the second latching protrusion 3210 and better mating with the first latching protrusion 3110, thus generating resistance to the second latching protrusion 3210. In this case, the first mating part 3100 can be a metal part or a hard plastic part.

[0082] Combination Figure 10 As shown, in some embodiments, the first mating component 3100 and the base 1000 are plugged into each other. For example, the first mating component 3100 is inserted into the interior of the base 1000 through the insertion port 1001 of the base 1000, which facilitates the assembly between the first mating component 3100 and the base 1000. In particular, the two can be interference-fitted, which can improve the stability of the assembly.

[0083] Optionally, the first mating component 3100 is provided with a first step 3120. When the first mating component 3100 is inserted into the base 1000 through the insertion port 1001 of the base 1000, the first step 3120 abuts against the periphery of the insertion port 1001 of the base 1000. This arrangement serves to position the insertion of the first mating component 3100, ensuring that the first mating component 3100 is installed in place and preventing the first mating component 3100 from being over-inserted.

[0084] Optionally, the first mating member 3100 is inserted into the base 1000 in a first direction, and the second mating member 3200 is adapted to generate a force in the first direction on the first mating member 3100 when it abuts against the first mating member 3100. The force generated when the second mating part 3200 and the first mating part 3100 abut against each other can be the total force generated by the second mating part 3200 on the first mating part 3100, or it can be a component force along the first direction. Since the first mating part 3100 abuts against the periphery of the insertion port 1001 of the base 1000 through the first step 3120 when it is inserted into the base 1000, that is, the first mating part 3100 is inserted into the base 1000 along the first direction until the first step 3120 abuts against the periphery of the insertion port 1001 of the base 1000, it indicates that the first mating part 3100 is inserted into place. As the support rod 2000 rotates, the second mating part 3200 and the first mating part 3100 abut against each other, thereby generating a force along the first direction on the first mating part 3100, so that the first mating part 3100 is pressed tightly against the base 1000 to prevent the first mating part 3100 from detaching from the base 1000.

[0085] Combination Figure 10As shown, in some embodiments, the second mating component 3200 and the support rod 2000 are plugged together. For example, the second mating component 3200 is inserted into the interior of the support rod 2000 through the insertion port 2001 of the support rod 2000, which facilitates the assembly between the second mating component 3200 and the support rod 2000. In particular, the two can be interference-fitted, which can improve the stability of the assembly.

[0086] Optionally, the second mating component 3200 is provided with a second step 3220. When the second mating component 3200 is inserted into the support rod 2000 through the insertion port 2001 of the support rod 2000, the second step 3220 and the periphery of the insertion port 2001 of the support rod 2000 abut against each other. This arrangement serves to position the insertion of the second mating component 3200, ensuring that the second mating component 3200 is installed in place and preventing the second mating component 3200 from being over-inserted.

[0087] Optionally, the second mating member 3200 is inserted into the support rod 2000 in the second direction, and the first mating member 3100 is adapted to generate a force in the second direction on the second mating member 3200 when it abuts against the second mating member 3200. The force generated when the first mating part 3100 and the second mating part 3200 abut against each other can be the total force generated by the first mating part 3100 on the second mating part 3200, or it can be a component force along the second direction. Since the second mating part 3200 abuts against the periphery of the insertion port 2001 of the support rod 2000 through the second step 3220 when it is inserted into the support rod 2000, that is, the second mating part 3200 is inserted into the support rod 2000 along the second direction until the second step 3220 abuts against the periphery of the insertion port 2001 of the support rod 2000, it indicates that the second mating part 3200 is inserted into place. As the support rod 2000 rotates, the first mating part 3100 and the second mating part 3200 abut against each other, thereby generating a force along the second direction, so that the second mating part 3200 presses tightly against the support rod 2000, preventing the second mating part 3200 from disengaging from the support rod 2000.

[0088] Combination Figure 3 , Figure 8 and Figure 10 As shown, in some embodiments, at least a portion of one of the first mating member 3100 and the second mating member 3200 is embedded inside the other. The first mating member 3100 is disposed on the base 1000, and the second mating member 3200 is disposed on the support rod 2000. When the support rod 2000 and the base 1000 are rotatably connected, one of the first mating member 3100 and the second mating member 3200 is embedded inside the other. This can be either at least a portion of the first mating member 3100 being embedded inside the second mating member 3200, or at least a portion of the second mating member 3200 being embedded inside the first mating member 3100, which helps to reduce the space occupied.

[0089] Combination Figure 3 and Figure 10 As shown, in some embodiments, the support rod 2000 and the base 1000 are rotatably connected by a first fastener 6100, for example, the first fastener 6100 is a rivet or a pivot. In addition, the first fastener 6100 also passes through the first mating member 3100 and the second mating member 3200, thus further tightening the first mating member 3100 and the second mating member 3200, which helps to prevent the first mating member 3100 and the second mating member 3200 from becoming loose.

[0090] Combination Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 , Figures 9 to 12 As shown, in some embodiments, the bracket further includes a crossbar 4000, a third mating member 5000, and a second fastener 6200. The crossbar 4000 passes through and intersects with the support rod 2000. The third mating member 5000 is disposed between the crossbar 4000 and the support rod 2000. The second fastener 6200 is connected to the support rod 2000 and supports the third mating member 5000, so that the third mating member 5000 abuts against the crossbar 4000. Through the arrangement of the third mating member 5000, when the second fastener 6200 supports the third mating member 5000, the third mating member 5000 abuts against the crossbar 4000 and generates force, thereby pressing the crossbar 4000. Furthermore, the third mating member 5000 can deform, which can increase the contact area between the third mating member 5000 and the crossbar 4000, improve the pressing effect on the crossbar 4000, and ensure the relative fixation between the crossbar 4000 and the support rod 2000.

[0091] For example Figure 1 and Figure 2 As shown, there are two bases 1000 and two support rods 2000. One end of each support rod 2000 is rotatably connected to one of the two bases 1000. A crossbar 4000 is connected between the other ends of the two support rods 2000. A third mating part 5000 is provided between the crossbar 4000 and the support rods 2000. By connecting the second fastener 6200 to the support rod 2000, the third mating part 5000 is supported, so that the third mating part 5000 abuts against the crossbar 4000, thus realizing the connection between the crossbar 4000 and the support rods 2000.

[0092] To facilitate the connection of the second fastener 6200 to the strut 2000, combined with Figure 11As shown, in some embodiments, the second fastener 6200 includes an operating portion 6210 and a threaded portion 6220. The support rod 2000 is provided with a threaded hole 2200. The operating portion 6210 is adapted for a user to hold, and the threaded portion 6220 is adapted to be screwed into the threaded hole 2200 to support the third mating member 5000. The user can directly operate the threaded portion 6220 to be screwed into the threaded hole 2200 by holding the operating portion 6210. In this process, the threaded portion 6220 supports the third mating member 5000, which is convenient and quick.

[0093] Combination Figure 11 As shown, in some embodiments, the strut 2000 is provided with a first through hole 2100, the third mating member 5000 is provided with a second through hole 5200, and the third mating member 5000 and the strut 2000 are connected by insertion so that the first through hole 2100 and the second through hole 5200 are connected, and the crossbar 4000 passes through the first through hole 2100 and the second through hole 5200. For example, the third mating part 5000 is inserted into the end of the support rod 2000 (one end of the support rod 2000 is rotatably connected to the base 1000, so the other end of the support rod 2000 is for the third mating part 5000 to insert into), thereby closing the end of the support rod 2000. When the third mating part 5000 is inserted into place, the first through hole 2100 and the second through hole 5200 can be connected. In this way, the crossbar 4000 can pass through the first through hole 2100 and the second through hole 5200, and the support rod 2000 supports the crossbar 4000. At this time, the third mating part 5000 is located between the support rod 2000 and the crossbar 4000. By connecting the second fastener 6200 to the support rod 2000, the third mating part 5000 can be supported, thereby making the third mating part 5000 abut against the crossbar 4000.

[0094] Optionally, the interference fit between the third mating part 5000 and the strut 2000 is more conducive to the initial positioning and assembly of the third mating part 5000 and the strut 2000. Similarly, the interference fit between the third mating part 5000 and the crossbar 4000 is also conducive to the initial positioning and assembly of the third mating part 5000 and the crossbar 4000.

[0095] Combination Figure 11As shown, in some embodiments, the third mating member 5000 is provided with a movable abutment portion 5100, and the second fastener 6200 is adapted to support the abutment portion 5100 so that the abutment portion 5100 abuts against the crossbar 4000. By providing a movable abutment portion 5100, when the second fastener 6200 supports the abutment portion 5100, it is easier for the abutment portion 5100 to deform and abut against the crossbar 4000. Optionally, the third mating member 5000 is made of plastic, which facilitates the movable setting of the abutment portion 5100 and also helps to increase the friction between it and the crossbar 4000. Optionally, the third mating member 5000 is a one-piece molded part, that is, it is manufactured by a one-piece molding process, so that the movement of the abutment portion 5100 is not easy to break. A through groove is provided around the abutment portion 5100 to achieve mobility.
