Description

Technical Field

[0001] The utility model belongs to the technical field of children's products, and particularly relates to a baby crib frame. Background Art

[0002] The existing baby cribs on the market are not convenient to fold. When sold, only the various components of the baby crib can be placed in the packaging box, and consumers need to install them by themselves after buying them back.

[0003] Since each component cannot be folded and the support legs cannot be disassembled, the packaging box is relatively large and takes up a large amount of space during transportation.

[0004] During the use process by consumers, problems such as poor stability are likely to occur.

[0005] Therefore, we have developed a baby crib with support legs and guardrails that can both be folded, enabling installation-free, small space occupation during transportation, and good stability. Summary of the Utility Model

[0006] In view of the above problems, the utility model designs a baby crib frame, which includes a bed leg structure and a guardrail. The bed leg structure includes two support legs, and each support leg includes a leg part one and a leg part two. A folding locking mechanism one is arranged between the leg part one and the leg part two.

[0007] The upper ends of the leg part one and the leg part two are hinged with a connecting seat one, and a lifting adjustment mechanism is arranged on the connecting seat one.

[0008] A folding locking mechanism two is arranged on the guardrail, and the folding locking mechanism two is connected with the lifting adjustment mechanism.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: By arranging the folding locking mechanism one between the leg part one and the leg part two, the folding of the legs of the baby crib is facilitated. By hinging the upper ends of the leg part one and the leg part two with the connecting seat one, a stable triangular structure is formed in the unfolded state of the bed leg structure, avoiding the problem of poor stability that is likely to occur during the use process by consumers. By arranging the lifting adjustment mechanism on the connecting seat one and connecting the folding locking mechanism two with the lifting adjustment mechanism, the height of the baby crib can be adjusted to facilitate taking care of the baby. By arranging the folding locking mechanism two on the guardrail, the folding of the guardrail is facilitated. Through the folding of the bed legs and the guardrail, the overall folding of the baby crib is realized, achieving an installation-free, small space occupation during transportation, and good stability baby crib.

[0010] Furthermore, the folding locking mechanism one includes a connecting seat two. A clamping mechanism is arranged on the connecting seat two. A rotating part one and a rotating part two are rotatably arranged on the connecting seat two. The rotating part one and the rotating part two are respectively connected with the leg part one and the leg part two, and the rotating part one and the rotating part two cooperate with the clamping mechanism to lock.

[0011] The beneficial effects of adopting the above further technical solution are as follows: By the cooperation and locking of the first rotating member and the second rotating member with the clamping mechanism, the locking after the unfolding of the first leg member and the second leg member is realized, avoiding the rotation of the first leg member and the second leg member.

[0012] Further, the clamping mechanism includes a first elastic member, a clamping block is arranged on the first elastic member, a telescopic cavity is arranged on the second connecting seat, and the first elastic member and the clamping block are arranged in the telescopic cavity.

[0013] The beneficial effects of adopting the above further technical solution are as follows: By pressing the first elastic member, the clamping block is driven to move in the telescopic cavity, realizing the clamping or loosening of the cooperation between the clamping mechanism and the first rotating member and the second rotating member.

[0014] Further, a first gear and a second gear are arranged on both the first rotating member and the second rotating member, the first gear and the second gear are meshed, a first limiting groove and a second limiting groove are arranged on the first rotating member and the second rotating member, and the shapes of the first limiting groove and the second limiting groove match the shape of the clamping block.

[0015] The beneficial effects of adopting the above further technical solution are as follows: By the meshing of the first gear and the second gear, the first rotating member and the second rotating member rotate synchronously, thereby driving the first leg member and the second leg member to fold or unfold synchronously. When the first limiting groove and the second limiting groove are clamped with the clamping block, the first leg member and the second leg member are in the unfolded and locked state. When the first limiting groove and the second limiting groove are loosened from the clamping block, the first rotating member and the second rotating member rotate, so that the first leg member and the second leg member are simply folded.

[0016] Further, the first connecting seat includes a first connecting cavity, a connecting shaft is arranged in the first connecting cavity, and the connecting shaft is hinged to the upper ends of the first leg member and the second leg member.

[0017] The beneficial effects of adopting the above further technical solution are as follows: By the hinge connection of the connecting shaft with the upper ends of the first leg member and the second leg member, a stable triangular structure is formed after the bed legs are unfolded and locked, and the upper ends of the first leg member and the second leg member rotate with the first connecting seat, so as to fold the first leg member and the second leg member.

[0018] Further, the lifting and adjusting mechanism includes a sleeve, a plurality of limiting holes are arranged on the sleeve, and a lifting and locking mechanism is arranged in the sleeve.

[0019] The beneficial effects of adopting the above further technical solution are as follows: By the cooperation of the lifting and locking mechanism in the sleeve and the limiting holes, the lifting and locking mechanism slides up and down in the sleeve, thereby adjusting the height of the baby crib.

[0020] Further, the lifting and locking mechanism includes a lifting rod and a fixed frame. An active cavity one and an active cavity two are arranged inside the lifting rod. The active cavity one and the active cavity two are communicated in sequence. A clamping member is arranged inside the active cavity one. A lifting member is arranged on the clamping member. An elastic member two is arranged between the lifting member and the upper wall of the active cavity one;

[0021] A limiting groove three is arranged inside the active cavity one. The clamping member is arranged inside the limiting groove three. An elastic member three is arranged between the clamping member and the bottom wall of the limiting groove three. A pulling wire is arranged inside the active cavity two. One end of the lifting member is connected to the pulling wire. The fixed frame is arranged on the lifting rod. A clamping frame is opened on the fixed frame. A lifting block is arranged inside the clamping frame. The other end of the pulling wire is connected to the lifting block. A clamping hole is arranged on the lifting rod. The clamping member is movably arranged inside the clamping hole;

[0022] Preferably, the clamping member includes a convex block. The lifting member includes a sliding block and a sliding frame. The protruding part of the convex block is located inside the sliding frame. The surfaces of the convex block in contact with the sliding frame are both composed of a horizontal plane and an inclined plane. The convex block fits with the clamping hole. The sliding block is connected to the pulling wire.

[0023] The beneficial effects of adopting the above further technical solution are as follows: By pressing the lifting block to drive the pulling wire to move upward, thereby driving the lifting member to move upward. The lifting member presses the elastic member two upward and moves upward inside the active cavity one, thereby driving the clamping member to press the elastic member three, so that the clamping member disengages from the clamping hole, enabling the sleeve and the lifting rod to cooperate and slide, realizing the lifting of the lifting rod; When it rises to a suitable height, release the lifting block. Under the reset action of the elastic member two and the elastic member three, the lifting member moves downward inside the active cavity one, and the clamping member resets and cooperates with the clamping hole to lock; Since the protruding part of the convex block is located inside the sliding frame, the surfaces of the convex block in contact with the sliding frame are both composed of a horizontal plane and an inclined plane, and the convex block fits with the clamping hole. When the lifting member moves upward, the clamping member is limited in the limiting groove. The protruding part of the convex block is located inside the sliding frame. The inclined plane of the lifting member provides a certain pressure to the inclined plane of the clamping member, driving the convex block to disengage from the clamping hole, thus simply realizing the height adjustment of the baby crib.

[0024] Further, the folding and locking mechanism two includes a fixed seat. A sliding cavity is arranged inside the fixed seat. A sliding member is arranged inside the sliding cavity. A pushing member is arranged on the fixed seat. The pushing member and the sliding member cooperate to slide;

[0025] A connecting cavity two is arranged on the fixed seat. Two rotating members three are rotatably arranged inside the connecting cavity two. The connecting cavity two is communicated with the sliding cavity. The rotating member three and the sliding member cooperate to lock. The rotating member three is connected to the guardrail.

[0026] The beneficial effects of adopting the above further technical solution are as follows: By pressing the pushing member, the sliding member is driven to slide downward in the sliding cavity, and the third rotating member is no longer engaged and locked with the sliding member. Rotate the third rotating member to move downward in the second connecting cavity, so that the guardrail is folded. Rotate the two third rotating members to move upward in the second connecting cavity. When the two third rotating members are in the horizontal unfolded state, the third rotating member cannot rotate upward any more, and the sliding member is locked with the third rotating member, thus realizing the simple folding and unfolding of the guardrail.

[0027] Further, an elastic member four is arranged in the sliding cavity. One end of the elastic member four is connected to the sliding member, and the other end of the elastic member four is connected to the fixed seat;

[0028] A limiting post is arranged on the sliding member, and a third gear and a fourth limiting groove are arranged on each of the two third rotating members. The limiting post is engaged and locked with the fourth limiting groove.

[0029] The beneficial effects of adopting the above further technical solution are as follows: By pressing the pushing member, the sliding member slides downward in the sliding cavity in cooperation with the elastic member four, the limiting post disengages from the limiting groove, and the rotating member rotates downward to move in the second connecting cavity. The third gears arranged on the two third rotating members are meshed with each other, so that the guardrail is folded. Rotate the two third rotating members upward. When the third rotating member is in the horizontal state and cannot rotate upward in the second connecting cavity, the sliding member drives the limiting post to enter the fourth limiting grooves of the two third rotating members under the reset action of the elastic member four, thereby locking the third rotating member and preventing the third rotating member from rotating downward.

[0030] Further, the surfaces of the sliding member and the pushing member in contact are both inclined planes, and the sliding member and the pushing member are perpendicular;

[0031] A positioning hole is formed in the sliding member, and the elastic member four is arranged in the positioning hole.

[0032] The beneficial effects of adopting the above further technical solution are as follows: Since the surfaces of the sliding member and the pushing member in contact are both inclined planes and the sliding member and the pushing member are perpendicular, pressing the pushing member to move inward gives a certain pressure from the inclined plane of the pushing member to the inclined plane of the sliding member, causing the sliding member to move downward. Since a positioning hole is formed in the sliding member and the elastic member four is arranged in the positioning hole, the sliding member moves downward and compresses the elastic member four, thereby folding the guardrail. When the elastic member four resets, the guardrail is unfolded and locked, avoiding the displacement of the elastic member and the uneven elastic compression force affecting the folding and unfolding of the guardrail.

By hinging the first connecting seat 130 to the upper ends of the first leg member 101 and the second leg member 102, the leg structure 100 forms a stable triangular structure in the unfolded state, avoiding the problem of poor stability that is likely to occur during the use by consumers; by providing the lifting and adjusting mechanism 400 on the first connecting seat 130 and connecting the second folding and locking mechanism 500 to the lifting and adjusting mechanism 400, the height of the baby crib is adjusted to facilitate taking care of the baby; by providing the second folding and locking mechanism 500 on the guardrail 200, the folding of the guardrail 200 is facilitated; through the folding of the legs and the guardrail 200, the overall folding of the baby crib is realized, achieving a baby crib that is easy to install, occupies little space during transportation, and has good stability.

[0052] As Figures 1-3 shown: As an implementation manner, the first folding and locking mechanism 300 includes a second connecting seat 310. A clamping mechanism 320 is provided on the second connecting seat 310. A first rotating member 330 and a second rotating member 340 are rotatably provided on the second connecting seat 310. The first rotating member 330 and the second rotating member 340 are respectively connected to the first leg member 101 and the second leg member 102, and the first rotating member 330 and the second rotating member 340 cooperate with the clamping mechanism 320 to lock; through the cooperation and locking of the first rotating member 330 and the second rotating member 340 with the clamping mechanism 320, the locking of the first leg member 101 and the second leg member 102 after unfolding is realized, avoiding the rotation of the first leg member 101 and the second leg member 102.

[0053] As Figures 3-5 shown: The clamping mechanism 320 includes a first elastic member 321. A clamping block 322 is provided on the first elastic member 321. A telescopic cavity 323 is provided on the second connecting seat 310. The first elastic member 321 and the clamping block 322 are provided in the telescopic cavity 323; by pressing the first elastic member 321, the clamping block 322 is driven to move in the telescopic cavity 323, realizing the cooperation of the clamping mechanism 320 with the first rotating member 330 and the second rotating member 340 to be clamped or released. The first elastic member 321 can be composed of a spring and a housing.

[0054] Both the first rotating member 330 and the second rotating member 340 are provided with a first gear 331 and a second gear 341. The first gear 331 meshes with the second gear 341. The first rotating member 330 and the second rotating member 340 are provided with a first limiting groove 332 and a second limiting groove 342, and the first limiting groove 332 and the second limiting groove 342 are in conformity with the shape of the clamping block 322. Through the meshing of the first gear 331 and the second gear 341, the first rotating member 330 and the second rotating member 340 rotate synchronously, thereby driving the first leg member 101 and the second leg member 102 to fold or unfold synchronously. The first limiting groove 332 and the second limiting groove 342 are clamped with the clamping block 322, and the first leg member 101 and the second leg member 102 are in the unfolded and locked state. When the first limiting groove 332 and the second limiting groove 342 are loosened from the clamping block 322, the first rotating member 330 and the second rotating member 340 rotate, thereby enabling the first leg member 101 and the second leg member 102 to perform simple folding.

[0055] As Figure 1 and 6 shown: The first connecting seat 130 includes a first connecting cavity 131. A connecting shaft is arranged in the first connecting cavity 131, and the connecting shaft is hinged to the upper ends of the first leg member 101 and the second leg member 102. By hinging the connecting shaft to the upper ends of the first leg member 101 and the second leg member 102, a stable triangular structure is formed after the bed legs are unfolded and locked, enabling the upper ends of the first leg member 101 and the second leg member 102 to rotate with the first connecting seat 130, thereby folding the first leg member 101 and the second leg member 102.

[0056] As Figure 6 shown: The lifting and adjusting mechanism 400 includes a sleeve 410. A plurality of limiting holes 411 are arranged on the sleeve 410, and a lifting and locking mechanism is arranged in the sleeve 410. By the cooperation of the lifting and locking mechanism in the sleeve 410 with the limiting holes 411, the lifting and locking mechanism slides up and down in the sleeve 410, thereby adjusting the height of the baby crib.

[0057] As Figures 7-8As shown in the figure: The lifting and locking mechanism includes a lifting rod 420 and a fixed frame 430. An active cavity one and an active cavity two are arranged inside the lifting rod 420. The active cavity one and the active cavity two are communicated in sequence. A clamping member 440 is arranged inside the active cavity one. A lifting member 450 is arranged on the clamping member 440. An elastic member two 460 is arranged between the lifting member 450 and the upper wall of the active cavity one. A limiting groove three 421 is arranged inside the active cavity one. The clamping member 440 is arranged inside the limiting groove three 421. An elastic member three is arranged between the clamping member 440 and the bottom wall of the limiting groove three. A pulling wire 422 is arranged inside the active cavity two. One end of the lifting member 450 is connected to the pulling wire 422. The fixed frame 430 is arranged on the lifting rod 420. A clamping frame 431 is opened on the fixed frame 430. A pulling block 432 is arranged inside the clamping frame 431. The other end of the pulling wire 422 is connected to the pulling block 432. A clamping hole 423 is arranged on the lifting rod 420. The clamping member 440 is movably arranged inside the clamping hole 423. An elastic member five is arranged on the fixed frame 430. The elastic member five cooperates with the folding locking mechanism two 500 for locking. The elastic member five is composed of a spring and a housing. By pressing the pulling block 432 to drive the pulling wire 422 to move upward, the lifting member 450 is driven to move upward. The lifting member 450 presses the elastic member two 460 upward and moves upward inside the active cavity one, thereby driving the clamping member 440 to press the elastic member three, so that the clamping member 440 disengages from the clamping hole 423, enabling the sleeve 410 and the lifting rod 420 to cooperate and slide, realizing the lifting of the lifting rod 420. When rising to an appropriate height, release the pulling block 432. Under the reset action of the elastic member two 460 and the elastic member three, the lifting member 450 moves downward inside the active cavity one, and the clamping member 440 resets and cooperates with the clamping hole 423 for locking.

[0058] As Figures 7-10 shown: Preferably, the clamping member 440 includes a convex block 441, and the lifting member 450 includes a sliding block 451 and a sliding frame 452. The protruding part of the convex block 441 is located inside the sliding frame 452. The surfaces of the convex block 441 in contact with the sliding frame 452 are both composed of a horizontal plane and an inclined plane. The convex block 441 fits with the clamping hole 423. The sliding block 451 is connected to the pulling wire 422. By the protruding part of the convex block 441 being located inside the sliding frame 452, the surfaces of the convex block 441 in contact with the sliding frame 452 are both composed of a horizontal plane and an inclined plane, and the convex block 441 fits with the clamping hole 423. When the lifting member 450 moves upward, the clamping member 440 is limited inside the limiting groove three 421. The protruding part of the convex block 441 is located inside the sliding frame 452. The inclined plane of the lifting member 450 provides a certain pressure to the inclined plane of the clamping member 440, driving the convex block 441 to disengage from the clamping hole 423, thus simply realizing the height adjustment of the baby crib.

[0059] As Figures 11-13As shown in the figure: The folding and locking mechanism II 500 includes a fixed seat 510. A sliding cavity 511 is provided inside the fixed seat 510. A sliding member 520 is arranged inside the sliding cavity 511. A pushing member 530 is arranged on the fixed seat 510. The pushing member 530 cooperates with the sliding member 520 for sliding. Two rotating members III 540 are rotatably arranged inside a second connecting cavity on the fixed seat 510. The second connecting cavity communicates with the sliding cavity 511. The rotating member III 540 cooperates with the sliding member 520 for locking. The rotating member III 540 is connected to the guardrail 200. A third connecting cavity is provided at the lower end of the fixed seat 510. The third connecting cavity is connected to the fixed frame 430. A hole is formed on one side of the third connecting cavity. An elastic member V is movably arranged inside the hole. By pressing the pushing member 530, the sliding member 520 is driven to slide downward inside the sliding cavity 511. The rotating member III 540 and the sliding member 520 no longer cooperate for locking. The rotating member III 540 rotates downward and moves inside the connecting cavity, causing the guardrail 200 to fold. Rotate the two rotating members III 540 to move upward inside the connecting cavity. When the two rotating members III 540 are in a horizontally unfolded state, the rotating member III 540 cannot rotate upward any further. The sliding member 520 and the rotating member III 540 are locked, thus realizing the simple folding and unfolding of the guardrail 200.

[0060] As Figures 11-15 shown in the figure: An elastic member IV 512 is arranged inside the sliding cavity 511. One end of the elastic member IV 512 is connected to the sliding member 520, and the other end of the elastic member IV 512 is connected to the fixed seat 510. A limiting post 521 is arranged on the sliding member 520. A gear III 541 and a fourth limiting groove 542 are arranged on each of the two rotating members III 540. The limiting post 521 cooperates with the fourth limiting groove 542 for locking. By pressing the pushing member 530, the sliding member 520 cooperates with the elastic member IV and slides downward inside the sliding cavity 511. The limiting post 521 disengages from the fourth limiting groove 542. The rotating member rotates downward and moves inside the second connecting cavity. The gear III 541 arranged on each of the two rotating members III 540 meshes with each other, causing the guardrail 200 to fold. Rotate the two rotating members III 540 upward. When the rotating member III 540 is in a horizontal state and cannot rotate upward inside the connecting cavity, the sliding member 520 drives the limiting post 521 to enter the fourth limiting groove 542 of the two rotating members III 540 under the reset action of the elastic member IV, thus locking the rotating member III 540 and preventing the rotating member III 540 from rotating downward.

[0061] The elastic member II, the elastic member III, and the elastic member IV can be springs.

[0062] The surfaces of the sliding member 520 and the pushing member 530 in contact are both inclined planes, and the sliding member 520 and the pushing member 530 are perpendicular to each other; a positioning hole 522 is formed in the sliding member 520, and the fourth elastic member 512 is arranged in the positioning hole 522; since the surfaces of the sliding member 520 and the pushing member 530 in contact are both inclined planes, and the sliding member 520 and the pushing member 530 are perpendicular to each other, when the pushing member 530 is pressed to move inward, a certain pressure is applied to the inclined plane of the sliding member 520 by the inclined plane of the pushing member 530, causing the sliding member 520 to move downward. Since a positioning hole 522 is formed in the sliding member 520 and the fourth elastic member 512 is arranged in the positioning hole 522, when the sliding member 520 moves downward, the fourth elastic member 512 is compressed, thereby folding the guardrail 200. When the fourth elastic member 512 resets, the guardrail 200 is unfolded and locked, avoiding the displacement of the elastic member and uneven elastic compression force, which may affect the folding and unfolding of the guardrail 200.

[0063] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
