In addition, the terms 'first','second' are only used to distinguish in the description, and have no special meaning.

[0060] The technical scheme of the utility model will be further illustrated by specific embodiments in combination with the drawings.

[0061] The embodiment provides a locking structure, which reduces the influence of material on the locking effect, does not appear the case of damaging the locked structure, and does not easily appear the problem of locking failure, and has higher reliability.

[0062] As shown in Figures 1 to 23 The locking structure includes a base 1, a first fixing member 21, a second fixing member 22 and a limiting structure (not shown in the figure).

[0063] The base 1 is used to be connected with the component which needs to be locked. The base 1 can be an independent whole, or the base 1 can be connected with the carrier. It is understood that the base 1 can be a part of the carrier, such as a surrounding rod of a trolley.

[0064] At least one of the first fixing member 21 and the second fixing member 22 is movably connected with the base 1. The first fixing member 21 and / or the second fixing member 22 is movable relative to the base 1 to have a closed state and a separated state. For example, the first fixing member 21 and the second fixing member 22 are close to each other, or one of the first fixing member 21 and the second fixing member 22 is close to the other, so that the first fixing member 21 and the second fixing member 22 are in the closed state. In the closed state, the first fixing member 21 and the second fixing member 22 surround a containing space 100 (as shown in Figure 23 It is to be noted that the first fixing member 21 and the second fixing member 22 are in the closed state, and the component to be locked is in the containing space 100. When the first fixing member 21 and the second fixing member 22 are in the separated state, the component to be locked is out of the containing space 100.

[0065] In some optional embodiments, the first fixing member 21 and the second fixing member 22 can be fixedly arranged on the base 1, and the other is movably arranged on the base 1. The movable connection between the first fixing member 21 and the second fixing member 22 and the base 1 includes but is not limited to rotation and sliding. In other optional embodiments, the first fixing member 21 and the second fixing member 22 can be both slidably arranged on the base 1, or the first fixing member 21 and the second fixing member 22 can be both rotatably arranged on the base 1. The specific selection can be made according to actual needs, and the present embodiment does not limit the same.

[0066] It is to be noted that the containing space 100 in the present embodiment can be formed between the first fixing member 21 and the second fixing member 22, or the containing space 100 can be formed by the first fixing member 21, the second fixing member 22 and the base 1, and the present embodiment does not limit the same.

[0067] The containing space 100 is used to contain the component to be locked (such as a handle of a trolley). In the separated state, the first fixing member 21 and the second fixing member 22 can form a half-enclosing structure, that is, as shown in Figure 11 The first fixing member 21 and the second fixing member 22 surround a half-enclosed space 200, and one end of the first fixing member 21 is opposite to one end of the second fixing member 22. The component to be locked can enter between the first fixing member 21 and the second fixing member 22 (i.e. the half-enclosed space 200) through the opening of the half-enclosing structure, and then can be located in the containing space 100.

[0068] Optionally, in the folded state, one end of the first fixing member 21 abuts against one end of the second fixing member 22, which can form a relatively closed accommodation space 100, and can limit the movement of the first fixing member 21 and the second fixing member 22 so as not to continue moving.

[0069] In some optional embodiments, the first fixing member 21 and the second fixing member 22 are both rotationally connected to the base 1. For example, as shown in Figure 3 the first fixing member 21 is rotationally connected to the base 1 about a first axis 61, and the second fixing member 22 is rotationally connected to the base 1 about a second axis 62.

[0070] Optionally, the base has an accommodation groove (not shown in the figure), and the first fixing member 21 and the second fixing member 22 are at least partially located in the accommodation groove, so that the first fixing member 21 and the second fixing member 22 do not occupy a large space, which is beneficial to the miniaturization of the locking structure.

[0071] The limiting structure is arranged between the first fixing member 21 and the second fixing member 22, and is used to limit the movement of the first fixing member 21 and / or the second fixing member 22 relative to the base 1, so that the first fixing member 21 and the second fixing member 22 remain in the folded state.

[0072] For example, the limiting structure can be a locking member 3, which can lock the first fixing member 21 and the second fixing member 22 in the folded state. Of course, it can be understood that the limiting structure can also be achieved in other ways, such as buckles, magnetic attraction, etc., and the present embodiment does not limit this.

[0073] The locking structure provided by the present embodiment has at least one of the first fixing member 21 and the second fixing member 22 movably connected to the base 1, and has a folded state and a separated state. In the folded state, the first fixing member 21 and the second fixing member 22 can surround an accommodation space 100 for accommodating a to-be-locked member. The limiting structure is arranged between the first fixing member and the second fixing member, and is used to limit the movement of the first fixing member 21 and / or the second fixing member 22 relative to the base 1, so that the first fixing member 21 and the second fixing member 22 can remain in the folded state, thereby achieving the locking of the to-be-locked member. The materials of the base 1, the first fixing member 21, the second fixing member 22 and the locking member 3 do not affect the locking effect of the to-be-locked member, which reduces the influence of the materials on the locking effect, and the to-be-locked member is not damaged, and the locking failure problem is not easy to occur, which has high reliability.

[0074] In some optional embodiments, the limiting structure comprises a locking piece 3 arranged on one of the first fixing piece 21 and the second fixing piece 22, and a locking slot 221 arranged on the other of the first fixing piece 21 and the second fixing piece 22. The locking piece 3 is movably connected to one of the first fixing piece 21 and the second fixing piece 22, and the locking piece 3 is movable relative to the first fixing piece 21 or the second fixing piece 22 to have a locking position and an unlocking position.

[0075] When the locking piece 3 is in the locking position, the locking piece 3 is connected to the second fixing piece 22, for example, an end of the locking piece 3 away from the first fixing piece 21 is connected to the second fixing piece 22, so that the first fixing piece 21 and the second fixing piece 22 are connected by the locking piece 3, and thus the first fixing piece 21 and the second fixing piece 22 in the folded state cannot move relative to each other, that is, in the locking position, the locking piece 3 limits the movement of the first fixing piece 21 and the second fixing piece 22 relative to the base 1, so that the first fixing piece 21 and the second fixing piece 22 remain in the folded state. When the locking piece 3 is in the unlocking position, the locking piece 3 is separated from the second fixing piece 22, and at this time, the first fixing piece 21 and the second fixing piece 22 are no longer connected.

[0076] In some optional embodiments, the locking piece 3 is rotatably connected to the first fixing piece 21. For example, as shown in Figure 4 the locking piece 3 is rotatably connected to the base 1 about a third axis 63.

[0077] The locking structure provided by the embodiment, the first fixing piece 21 and the second fixing piece 22 are movably connected to the base 1 and have a folded state and an unfolded state, in the folded state, the first fixing piece 21 and the second fixing piece 22 can be arranged to form a containing space 100 for containing a to-be-locked piece, the first fixing piece 21 is connected with the locking piece 3, and the locking piece 3 has a locking position and an unlocking position, in the locking position, the locking piece 3 is connected to the second fixing piece 22, so that the first fixing piece 21 and the second fixing piece 22 cannot move relative to the base 1, so as to remain in the folded state, thereby achieving the locking of the to-be-locked piece. When the locking piece 3 is in the unlocking position, the locking piece 3 is separated from the second fixing piece 22, so that the first fixing piece 21 and the second fixing piece 22 can move relative to the base 1, thereby being able to move from the folded state to the unfolded state, achieving the locking and unlocking of the to-be-locked piece. The materials of the base 1, the first fixing piece 21, the second fixing piece 22 and the locking piece 3 do not affect the locking effect of the to-be-locked piece, reducing the influence of the materials on the locking effect, and the to-be-locked structure will not be damaged, and the problem of locking failure is not easy to occur, having high reliability.

[0078] For example, as shown in Figure 5As shown, in the locked position, the locking member 3 is positioned to the locking slot 221 to restrict the first fixing member 21 and / or the second fixing member 22 from moving relative to the base 1, so that the first fixing member 21 and the second fixing member 22 are kept in the folded state. For example, as shown in Figure 2 As shown, one end of the locking member 3 is a hook portion 35, which can be hooked in the locking slot 221 in the locked position, and the hook portion 35 cannot be separated from the locking slot 221 under the restriction of the slot wall of the locking slot 221. In the unlocked position, the locking member 3 is separated from the locking slot 221. For example, the locking member 3 can be pulled out of the locking slot 221 under the action of an external force to achieve separation from the locking slot 221.

[0079] In other optional embodiments, the locking member 3 and the second fixing member 22 can also be connected by magnetic attraction or the like, which is not limited in the present embodiment.

[0080] In the present embodiment, the length of the locking member 3 satisfies that the locking member 3 is just in the locked position when the first fixing member 21 and the second fixing member 22 are in the folded state.

[0081] For example, in order to make the length of the locking member 3 shorter and the structure more flexible, the end face of one end of the first fixing member 21 is used to form an opening communicating with the semi-closed space 200, the locking member 3 is arranged close to the one end of the first fixing member 21, the end face of one end of the second fixing member 22 is used to form an opening communicating with the semi-closed space 200, and the locking slot 221 is arranged close to the one end of the second fixing member 22, so that the length of the locking member 3 can be shorter.

[0082] One of the first fixing member 21 and the second fixing member 22, which is provided with the locking slot 221, is provided with a first guide inclined surface 222. The locking member 3 can slide on the first guide inclined surface 222, and the first guide inclined surface 222 is used to guide the locking member 3 to move to the locking slot 221. Through the guidance of the first guide inclined surface 222, the difficulty of positioning the locking member 3 to the locking slot 221 is reduced, the success rate of locking is improved, and the convenience of use is improved.

[0083] Optionally, referring to Figure 5 and Figure 6 , the locking member 3 is arranged on the first fixing member 21, and the locking slot 221 and the first guide inclined surface 222 are both arranged on the second fixing member 22.

[0084] Further optionally, the first guide inclined surface 222 is arranged on the end face of the second fixing member 22 opposite to the first fixing member 21 (or the end face of the first fixing member 21 opposite to the second fixing member 22), and is inclined from the end face to the locking slot 221, so as to be able to guide the locking member 3 into the locking slot 221. For example, the angle of the first guide inclined surface 222 can be 30°, 45°, 60°, etc., which is not limited in the present embodiment.

[0085] Optionally, as shown in Figure 4 the surface of the first fixing member 21 away from the second fixing member 22 is provided with a mounting seat 7. The mounting seat 7 is used for mounting the locking member 3. For example, the mounting seat 7 is provided with a first shaft 32, the locking member 3 is sleeved on the first shaft 32 and can rotate around the first shaft 32.

[0086] In some optional embodiments, please continue to refer to Figure 4 , the locking structure further comprises a first elastic member 31. Among them, the first elastic member 31 is arranged between the first fixing member 21 or the second fixing member 22 and the locking member 3, and always has a tendency to drive the locking member 3 to be positioned in the locking groove 221, so that the locking member 3 can be automatically moved to the locking groove 221 and positioned in the locking groove 221 under the driving of the first elastic member 31 during the movement of the first fixing member 21 and the second fixing member 22 from the separation state to the closing state, realizing automatic locking, more abundant function, more intelligent structure, and further improving the use convenience.

[0087] It should be noted that during the process of the first elastic member 31 pushing the locking member 3 to slide to the locking groove 221, the first guide inclined surface 222 can guide the sliding of the locking member 3, so that the locking member 3 can be smoothly positioned in the locking groove 221 under the cooperation of the first elastic member 31 and the first guide inclined surface 222.

[0088] For example, the first elastic member 31 can be a torsional spring. The main body of the torsional spring can be sleeved on the first shaft 32. One arm of the torsional spring abuts against the first fixing member 21 or the mounting seat 7, and the other arm of the torsional spring abuts against the locking member 3, so as to be able to apply a force to the locking member 3 to drive the locking member 3 to be positioned in the locking groove 221. Of course, it can be understood that the first elastic member 31 can also be other elastic components, which will not be enumerated one by one in this embodiment.

[0089] In some optional embodiments, as shown in Figure 2 , when the locking member 3 is rotatably connected to the first fixing member 21 or the second fixing member through the first shaft 32, one end of the locking member 3 is positioned in the locking groove 221. The other end of the locking member 3 is a pressing portion 33, and the first shaft 32 penetrates the middle part of the locking member 3. Pressing the pressing portion 33 can make the locking member 3 rotate around the first shaft 32, so that one end of the locking member 3 is separated from the locking groove 221. It can be seen that the unlocking step of the locking structure in this embodiment is relatively simple and convenient to operate. By providing the mounting seat 7, the pressing portion 33 has a certain distance from the surface of the first fixing member 21 away from the second fixing member 22, so that the pressing portion 33 has sufficient activity space to drive one end of the locking member 3 to exit the locking groove 221.

[0090] Optionally, when the first fixing member 21 and the second fixing member 22 are relatively movable relative to the base 1 to switch to the folded state, the first fixing member 21 or the second fixing member 22 can drive the locking member 3 to move, so that the locking member 3 moves from the unlocked position to the locked position, without manually driving the locking member 3 to move, further improving the convenience of use.

[0091] In some optional embodiments, please continue to refer to Figure 4 , the locking structure further comprises a second elastic member 4. The second elastic member 4 is arranged between the base 1 and the first fixing member 21 and always has a tendency to drive the first fixing member 21 to move to the separated state, so that when the locking member 3 is not connected to the first fixing member 21 and the second fixing member 22, the first fixing member 21 can be opened under the action of the second elastic member 4, so as to facilitate the to-be-locked member to enter the semi-enclosed space 200, without manually adjusting the position of the first fixing member 21, improving the convenience of use.

[0092] In this embodiment, the second elastic member 4 is a torsion spring, and the base 1 is provided with a second shaft (not shown in the figure), the main body of the torsion spring is sleeved on the second shaft, and the two arms of the torsion spring are respectively abutted with the base 1 and the first fixing member 21 and apply a force to the first fixing member 21 to rotate away from the second fixing member 22, so as to be movable to the separated state. Of course, it can be understood that the second elastic member 4 can also be other elastic components, which are not enumerated one by one in this embodiment.

[0093] Exemplarily, as Figure 3 shown, the base 1 is provided with a first limiting structure 11 for abutting with the first fixing member 21 to limit the first fixing member 21 to the separated state, that is, when the first fixing member 21 moves to the separated state, it will abut with the first limiting structure 11 and will not continue to move. For example, the first limiting structure 11 is a limiting block, and the first fixing member 21 is provided with a limiting sliding groove, and after the first fixing member 21 is moved to the position, the limiting block abuts with the groove wall of the limiting sliding groove to achieve limiting.

[0094] Optionally, as Figure 6 shown, the locking structure further comprises a third elastic member 5. The third elastic member 5 is arranged between the base 1 and the second fixing member 22 and always has a tendency to drive the second fixing member 22 to move to the separated state, so that when the locking member 3 is not connected to the first fixing member 21 and the second fixing member 22, the second fixing member 22 can be opened under the action of the third elastic member 5, so as to facilitate the to-be-locked member to enter the semi-enclosed space 200, without manually adjusting the position of the second fixing member 22, improving the convenience of use.

[0095] In the embodiment, the third elastic member 5 is a torsion spring, the base 1 is provided with a third shaft (not shown in the figure), the main body of the torsion spring is sleeved on the third shaft, and the two arms of the torsion spring are respectively abutted against the base 1 and the second fixing member 22 and apply a force to the second fixing member 22 to rotate away from the first fixing member 21, so as to be movable to the separated state. Of course, it can be understood that the third elastic member 5 can also be other elastic components, which are not enumerated one by one in the embodiment.

[0096] Exemplarily, as shown in Figure 3 , the base 1 is provided with a second limiting structure 12, the second limiting structure 12 is used for abutting against the second fixing member 22 to limit the second fixing member 22 to the separated state, that is, when the second fixing member 22 moves to the separated state, the second fixing member 22 will abut against the second limiting structure 12 and will not continue to move. For example, the second limiting structure 12 is a limiting block, and the second fixing member 22 is provided with a limiting sliding groove, after the second fixing member 22 is moved to the position, the limiting block abuts against the groove wall of the limiting sliding groove to achieve limiting.

[0097] Optionally, the first fixing member 21 is provided with a first pushing part 211, for example, the first pushing part 211 is arranged on one side of the first fixing member 21, and the second fixing member 22 is provided with a second pushing part 223, for example, the second pushing part 223 is arranged on one side of the second fixing member 22, and in the embodiment, the same side of the second fixing member 22 is provided with the second pushing part 223, that is, the side of the second fixing member 22 facing the first fixing member 21 is provided with the second pushing part 223.

[0098] In the separated state, as shown in Figure 14 , the first pushing part 211 intersects with the second pushing part 223, that is, the first pushing part 211 and the second pushing part 223 are arranged to cross in one direction, and when moving from the separated state to the closed state, the movements of the first pushing part 211 and the second pushing part 223 do not interfere with each other. It should be noted that one end of the first fixing member 21 is used to form an opening communicating with the semi-closed space 200, and the first pushing part 211 is at the other end of the first fixing member 21. One end of the second fixing member 22 is used to form an opening communicating with the semi-closed space 200, and the second pushing part 223 is at the other end of the second fixing member 22.

[0099] In this embodiment, when the to-be-locked member enters the accommodation space 100, the first fixing member 21 and the second fixing member 22 are pushed to switch to the closed state. Specifically, the first push part 211 and the second push part 223 are used to contact the to-be-locked member. When the to-be-locked member enters the accommodation space 100, the to-be-locked member pushes the first push part 211 and the second push part 223 to push the first fixing member 21 to rotate around the first axis 61 against the elastic force of the second elastic member 4 and push the second fixing member 22 to rotate around the second axis 62 against the elastic force of the third elastic member 5, until the first fixing member 21 and the second fixing member 22 surround to form the accommodation space 100.

[0100] For example, as shown in Figure 4 and Figure 6 , the first push part 211 and the second push part 223 are provided in plurality. Also, as shown in Figure 14 , the plurality of first push parts 211 and the plurality of second push parts 223 are staggered in one direction.

[0101] Optionally, the first limiting structure 11 can abut against the part of the first fixing member 21 other than the first push part 211. For example, the two adjacent first push parts 211 form a limiting sliding groove for abutting against the first limiting structure 11, and the first limiting structure 11 contacts the groove bottom of the limiting sliding groove. Similarly, the second limiting structure 12 can abut against the part of the second fixing member 22 other than the second push part 223. For example, the two adjacent second push parts 223 form a limiting sliding groove for abutting against the second limiting structure 12, and the second limiting structure 12 contacts the groove bottom of the limiting sliding groove.

[0102] In some optional embodiments, in the separated state, the orthographic projection of the locking member 3 on the first fixing member 21 is located outside the inner wall of the first fixing member 21, or in the separated state, the length of the locking member 3 extending out of the first fixing member 21 is less than the preset length, so that the locking member 3 does not affect the to-be-locked member to enter the semi-closed space 200, avoiding the interference between the locking member 3 and the to-be-locked member.

[0103] For example, as shown in Figure 2 and Figure 4 , the locking member 3 is provided with a second guide slope 34. In the separated state, the second guide slope 34 is arranged towards the to-be-positioned member, and the to-be-positioned member can slide on the second guide slope 34, so that the to-be-locked member cannot enter the semi-closed space 200 due to the jamming with the locking member 3, improving the reliability of the locking structure.

[0104] In some optional embodiments, in the locked position, the surface of the locking member 3 facing the first fixing member 21 is in contact with both the first fixing member 21 and the second fixing member 22, so as to be supported by the first fixing member 21 and the second fixing member 22 and improve the stability of the locking member 3 when locked. For example, the outer surfaces of the first fixing member 21 and the second fixing member 22 are both curved surfaces, and the surface of the locking member 3 facing the first fixing member 21 is also curved surface to achieve a close fit. In the unlocked position, due to the provision of the first elastic member 31, the surface of the locking member 3 facing the first fixing member 21 is in contact with the first fixing member 21, so as to be supported by the first fixing member 21.

[0105] This embodiment also provides a child product, including the locking structure described above. For example... Figure 7 and Figure 8 As shown, the children's product also includes a body 10 and a connecting rod 20 movably connected to the body 10. A locking structure is provided on the body 10 and is used to lock the connecting rod 20 within the accommodating space 100, thereby locking the connecting rod 20 onto the body 10; that is, the connecting rod 20 is the locking element mentioned above. In this embodiment, the base 1 can be connected to the body 10, or the base 1 can be part of the body 10.

[0106] For example, one end of the link 20 is rotatably connected to the body 10, such as the bottom end of the link 20 being rotatably connected to the body 10 about the fourth axis 30. The middle part or the other end of the link 20 can be placed in the receiving space 100, so that the link 20 can have a used state and a locked state, which improves the flexibility of use of the link 20 and facilitates the storage of the link 20.

[0107] The children's product provided in this embodiment can lock the linkage 20 and has a good locking effect, making it convenient to use.

[0108] It should be noted that the children's products in this embodiment can be strollers, trolleys, etc., and this embodiment does not limit them.

[0109] For example, the base 1 is disposed on the body 10, and the connecting rod 20 pushes the first fixing member 21 and the second fixing member 22 to move relative to the base 1. The first fixing member 21 drives the locking member 3 to move so that the locking member 3 moves from the unlocked position to the locked position. That is, in this embodiment, the locking of the locking structure is directly actuated by the connecting rod 20 that needs to be locked, with fewer manual steps involved, making it easy to use.

[0110] Below, taking the initial state as... Figure 9 The state shown provides a detailed explanation of the locking process of link 20.

[0111] like Figure 9As shown, link 20 is in the working state, and there is an angle greater than 90 degrees between link 20 and body 10. Furthermore, as... Figure 10 and Figure 11 As shown, the first fixing member 21 and the second fixing member 22 are in a separated state. An external force pushes the connecting rod 20 along... Figure 9 The N-axis rotates around the fourth axis 30, causing the connecting rod 20 to move closer to the locking structure. During this process, the connecting rod 20 gradually enters the semi-enclosed space 200. When the connecting rod 20 is thicker, it can be guided into the semi-enclosed space 200 by the second guide ramp 34 on the locking member 3.

[0112] When moving link 20 further, if Figures 12 to 14 As shown, the connecting rod 20 contacts the first actuating part 211 and the second actuating part 223, and pushes the first actuating part 211 and the second actuating part 223 to move. When the first actuating part 211 and the second actuating part 223 move, they drive the entire first fixing member 21 along... Figure 15 As shown, H moves around the first axis 61, simultaneously driving the entire second fixing member 22 along... Figure 15 The K-axis moves around the second axis 62 as shown. When the first fixing member 21 rotates, the locking member 3 moves synchronously with the first fixing member 21.

[0113] When the end of the first fixing member 21 facing away from the first actuating part 211 abuts against the end of the second fixing member 22 facing away from the second actuating part 223, the first fixing member 21 and the second fixing member 22 no longer rotate. At this time, the first fixing member 21 and the second fixing member 22 are in a closed state, and the connecting rod 20 is located in the accommodating space 100 formed by the first fixing member 21 and the second fixing member 22. During this process, such as Figures 16 to 19 As shown, the hook 35 of the locking member 3 contacts the first guide slope 222 and slides on the first guide slope 222. When it slides out of the first guide slope 222, under the action of the first elastic member 31, the locking member 3 moves along... Figure 19 The M-axis rotates around the third axis 63, allowing the hook 35 to engage with the locking groove 221. Furthermore, when the first fixing member 21 and the second fixing member 22 are in the closed state, the hook 35 of the locking member 3 is precisely positioned in the locking groove 221 and is in a locked state. At this time, the children's product presents... Figures 20 to 23 The state shown. (By) Figure 20 As shown, the connecting rod 20 can be set perpendicular to the body 10.

[0114] When it is needed to be unlocked, an external force presses the locking part of the locking member 3, so that the locking member 3 rotates along the reverse direction of M around the third axis 63, and then the hook part 35 exits the locking groove 221, and the locking member 3 is no longer connected with the first fixing member 21 and the second fixing member 22. Under the action of the second elastic member 4 and the third elastic member 5, the first fixing member 21 moves along the reverse direction of H around the first axis 61, and the second fixing member 22 moves along the reverse direction of K around the second axis 62, so that the first fixing member 21 and the second fixing member 22 move from the closing state to the separated state, until the first fixing member 21 abuts against the first limiting structure 11, and the second fixing member 22 abuts against the second limiting structure 12, so that the first fixing member 21 and the second fixing member 22 are in the separated state. At this time, the connecting rod 20 can exit the semi-closed space 200 and rotate along the reverse direction of N around the fourth axis 30 until it moves to the use state.
