Description

Technical Field

[0001] This utility model relates to the field of baby product technology, and in particular to an improved structure of a baby crib mobile. Background Technology

[0002] The existing crib mobile, as seen in Chinese Utility Model Patent CN205338365U, entitled "A Crib Mobile," authorized on June 29, 2016, includes a base, a support rod, a suspension rod, and a hanging toy. The base has a protrusion on its upper part and a first clamping wall and a second clamping wall opposite each other on its lower part, forming a cavity between the first and second clamping walls to accommodate the side wall of the crib. A first fastening bolt is installed at the bottom of the first clamping wall, and a second fastening bolt is installed at the bottom of the second clamping wall. The support rod is a straight rod with a groove at its bottom and a protrusion at its top. The vertical section of the suspension rod has a groove at its bottom, and the front end of the curved section of the suspension rod has a hook for hanging the hanging toy. This utility model increases the contact area between the crib mobile and the crib, significantly improving the stability of the crib mobile and reducing the likelihood of the base wobbling. This utility model allows adjustment of the number of support rods according to the height of the side wall of the crib to ensure the distance between the hanging toy and the baby is at the optimal level.

[0003] However, the above-mentioned crib mobile still has the following shortcomings: (1) The base and the suspension rod are connected by one or more support rods. The height adjustment of the suspension rod can only be done with the height of a single support rod as the smallest adjustment unit. It is impossible to achieve stepless adjustment of the height of the suspension rod. At the same time, the direction of the hook on the suspension rod is fixed and cannot achieve stepless adjustment of the rotation angle of the suspension rod, thus failing to meet more user needs. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an improved structure for a crib mobile that allows for stepless adjustment of the height and rotation angle of the support rod and crib mobile music box, and whose adjustment operation is simple and convenient.

[0005] The purpose of this utility model is achieved as follows:

[0006] An improved crib mobile structure includes a fixed base, a support rod, and a crib mobile music box. The music box is detachably mounted on one end of the support rod. The structure also includes a fixing sleeve. The fixed base has an inner groove, and several elastic fixing arms are arranged around the outer periphery of the upper opening of the inner groove. A connecting tube is fixed to the other end of the support rod. One end of the connecting tube passes through the fixing sleeve and is inserted into the inner groove. The fixing sleeve is connected to the outer periphery of the elastic fixing arms, and the inner sidewall of the fixing sleeve pushes the elastic fixing arms to clamp the connecting tube. In this improved crib mobile structure, the connecting tube can move and rotate on the inner groove of the fixed base, allowing the user to infinitely adjust the height and rotation angle of the support rod and the crib mobile music box on the fixed base. The adjustment operation is simple and convenient. Furthermore, the connecting tube is effectively fixed to the fixed base through the cooperation of the fixing sleeve and the elastic fixing arms.

[0007] The objective of this utility model can also be achieved by the following technical measures:

[0008] Specifically, the fixing sleeve is a hollow sleeve, and the inner wall of the hollow sleeve is inclined outward from top to bottom; so that the inner wall of the hollow sleeve is narrow at the top and wide at the bottom, which not only makes it easy for the hollow sleeve to be placed on the outer periphery of several elastic fixing arms, but also allows the upper inner wall of the hollow sleeve to push the elastic fixing arms to clamp the connecting pipe, thereby fixing the connecting pipe on the inner groove.

[0009] Specifically, the horizontal angle of the inner wall of the hollow sleeve is 'a', 90.1°≤a≤95°; within this range of inclination, the hollow sleeve can effectively perform its function, namely: facilitating the installation of the hollow sleeve and enabling the hollow sleeve to push the elastic fixing arm to clamp the connecting pipe.

[0010] Specifically, the angle α is 90.7°, which has a good implementation effect.

[0011] Specifically, the inner wall of the hollow sleeve is provided with internal threads, and the outer periphery of the several elastic fixing arms is provided with external threads, with the internal threads and external threads being screwed together. This connection method can effectively install the hollow sleeve on the several elastic fixing arms. At the same time, as the hollow sleeve rotates during installation, the inner wall of the hollow sleeve will gradually push the elastic fixing arms to clamp the connecting pipe, resulting in a good fixing effect.

[0012] Specifically, the fixed base is provided with a connecting rod, and the connecting rod has an inner groove. Several thin arms are integrally formed on the outer periphery of the upper opening of the inner groove. There are hollow gaps between adjacent thin arms. The thin arms constitute the elastic fixed arms. The hollow gaps make the thin arms have a certain elasticity, which is conducive to the thin arms to undergo elastic deformation to clamp the connecting tube. At the same time, the structure of the thin arms is simple and easy to implement.

[0013] Specifically, one end of the connecting tube is hemispherical, so that one end of the connecting tube can be inserted into the inner groove.

[0014] Specifically, the other end of the connecting tube is provided with a connecting through hole, the other end of the support rod is provided with a slot, and both sides of the support rod are provided with recessed portions. Two through holes are opened on the side wall of the slot to connect the slot with the recessed portions on both sides of the support rod. The other end of the connecting tube is inserted into the slot, and the connecting through hole corresponds to the position of the through hole. A connector passes through the through hole and the connecting through hole on one side of the support rod and connects to the through hole in the recessed portion on the other side of the support rod. Decorative covers are connected to the recessed portions on both sides of the support rod. The connector can be a common connecting screw, which makes the connection operation of the connecting tube at the other end of the support rod simple and convenient. At the same time, the decorative cover can also hide the connector, which helps to improve the overall aesthetics of the product.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) This crib mobile has an improved structure. The connecting tube can move and rotate on the inner groove of the fixed base, so that the user can infinitely adjust the height and rotation angle of the support rod and the crib mobile music box on the fixed base. The adjustment operation is simple and convenient. At the same time, the connecting tube can be fixed on the fixed base by the cooperation of the fixed sleeve and the elastic fixed arm, and the fixing effect is good.

[0017] (2) The inner wall of the hollow sleeve is narrow at the top and wide at the bottom, which makes it easy for the hollow sleeve to be placed on the outer periphery of several elastic fixing arms, and also allows the upper inner wall of the hollow sleeve to push the elastic fixing arms to clamp the connecting pipe, thereby fixing the connecting pipe on the inner groove.

[0018] (3) The hollow space makes the thin arm have a certain elasticity, which is conducive to the thin arm to undergo elastic deformation to clamp the connecting pipe. At the same time, the structure of the thin arm is simple and easy to implement. Attached Figure Description

The fixed base 1 has an inner groove 11, and several elastic fixing arms 12 are arranged around the outer periphery of the upper opening of the inner groove 11. A connecting tube 5 is fixed to the other end of the support rod 2. One end of the connecting tube 5 passes through the fixing sleeve 4 and is inserted into the inner groove 11. The fixing sleeve 4 is connected to the outer periphery of the several elastic fixing arms 12, and the inner sidewall of the fixing sleeve 4 pushes the several elastic fixing arms 12 to clamp the connecting tube 5.

[0026] As a specific solution, the fixing sleeve 4 is a hollow sleeve, and the inner sidewall of the hollow sleeve is inclined outward from top to bottom.

[0027] In this embodiment, the horizontal angle of the inner wall of the hollow sleeve is 'a', 90.1°≤a≤95°; the hollow sleeve can function well within this range of inclination.

[0028] In this embodiment, the horizontal clamping angle 'a' is 90.7°. The specific value of the horizontal clamping angle 'a' is related to the specific height of the hollow sleeve. The smaller the value of the horizontal clamping angle 'a', the larger the height of the hollow sleeve needs to be to ensure the clamping effect. For example, the specific height of the hollow sleeve corresponding to this value of the horizontal clamping angle 'a' is 47mm. Of course, the specific value of the horizontal clamping angle 'a' is also related to the hardness of the materials of the hollow sleeve and the elastic fixing arm. In this embodiment, the hollow sleeve and the elastic fixing arm are ordinary plastic parts.

[0029] As a more specific embodiment, the inner wall of the hollow sleeve is provided with an internal thread 41, and the outer periphery of several elastic fixing arms 12 is provided with an external thread 13, with the internal thread 41 and the external thread 13 being screwed together.

[0030] As a more specific solution, the fixed base 1 is provided with a connecting rod 14, the connecting rod 14 has an inner groove 11, and the upper opening of the inner groove 11 has several thin arms integrally formed on the outer periphery, with a hollow gap 15 between adjacent thin arms, the thin arms forming the elastic fixed arm 12.

[0031] In this embodiment, one end of the connecting pipe 5 is hemispherical.

[0032] In a preferred embodiment, the other end of the connecting pipe 5 is provided with a connecting through hole 51, and the other end of the support rod 2 is provided with a slot 21. Both sides of the support rod 2 are provided with recesses 22. Two through holes 23 are opened on the side wall of the slot 21 to allow the slot 21 to communicate with the recesses 22 on both sides of the support rod 2.
