Description

Technical Field

[0001] The utility model belongs to the technical field of bathing racks, and particularly relates to a children's bathing rack. Background Technique

[0002] A children's bathing rack is a tool to assist parents in bathing infants and young children. It can support infants and young children, thus facilitating parents to clean the bodies of infants and young children.

[0003] Most children's bathing racks are movably provided with armrests to restrict the activities of infants and young children. For example, a children's standing assistance device disclosed in Chinese Utility Model Patent CN202322920209.7 includes a base, a connecting rod, a connecting seat, an armrest assembly rotatably installed on the connecting seat, and a rotating assembly elastically installed on the armrest assembly. The connecting seat is installed on the base through the connecting rod in a vertically adjustable manner. The connecting seat is provided with a first bevel gear, and the rotating assembly is correspondingly provided with a second bevel gear. When the first bevel gear meshes with the second bevel gear, the armrest assembly can rotate unidirectionally inward relative to the connecting seat. In this structure, the armrest assembly can rotate unidirectionally inward relative to the connecting axis, with the function of reverse locking, and the opening degree between the armrest assemblies can be adjusted with one hand.

[0004] In the above structure, pressing the rotating assembly can control the separation of the first bevel gear and the second bevel gear, which is convenient for users to control. However, during use, infants and young children are prone to accidentally touch it, resulting in the accidental separation of the first bevel gear and the second bevel gear, thereby causing the opening degree between the armrest assemblies to accidentally become larger, which is likely to lead to accidents.

The armrest body and the hinge seat 2223 are relatively fixed by cooperation; a driving member 33 is slidably arranged on the armrest body, and the sliding direction of the driving member 33 is relatively inclined or relatively perpendicular to the movement direction of the locking member 4. The driving member 33 is provided with a toggle portion 331 and a first driving surface 332 which is inclined to the sliding direction of the driving member 33; a control groove 321 is provided on the outer wall of the armrest body, and the toggle portion 331 is penetrated into the control groove 321; by pushing the toggle portion 331 to slide in the control groove 321, the first driving surface 332 can drive the locking member 4 to disengage from the positioning portion 2225, so that the armrest body and the hinge seat 2223 can rotate relative to each other.

[0046] In the above structure, since the first driving surface 332 and the driving member 33 are inclined in the sliding direction, and the toggle portion 331 needs to be pushed to slide in the control groove 321 during use, so that the first driving surface 332 can drive the locking member 4 to disengage from the positioning portion 2225. This structure requires the user to push the toggle portion 331, and since the toggle portion 331 is inserted into the control groove 321, it can prevent infants and young children from accidentally pressing the driving member 33 during bathing, causing the armrest assembly 3 to accidentally unfold outward, which is beneficial to improving the safety of the children's bathing rack. In addition, this structure is more convenient for adults to carry out and is convenient for adults to use and control.

[0047] In this embodiment, the locking member 4 is provided with a first clamping surface 43 adapted to the first driving surface 332.

The armrest assembly 3 is also provided with a fourth elastic member 34 for driving the driving member to reset.

[0048] In the present utility model, the support assembly 2 includes a mounting rod 21 and an extension bracket 22 which are slidably connected. The mounting rod 21 is detachably arranged on the base 1. The armrest assembly 3 is arranged on the extension bracket 22. A clamping member 216 and a second elastic member 217 are movably arranged on the base 1. At least two clamping grooves 2211 adapted to the clamping member 216 are arranged at intervals on the extension bracket 22. When the clamping member 216 cooperates with different clamping grooves 2211, the distance between the extension bracket 22 and the base 1 is different. The structures of the clamping member 216 and at least two clamping grooves 2211 are beneficial for the user to adjust the height of the armrest assembly 3 according to the application and height, which is convenient for the user to use. The setting of the second elastic member 217 facilitates the clamping member 216 to remain in cooperation with the clamping groove 2211, avoiding accidental telescoping of the mounting rod 21 and the extension bracket 22 during use.

[0049] The mounting rod 21 includes a left housing 211 and a right housing 212 which are detachably connected. A chute 219 adapted to the extension rod is formed between the left housing 211 and the right housing 212. Protrusion portions 2111 are arranged on both the left housing 211 and the right housing 212. The protrusion portions 2111 on the left housing 211 and the right housing 212 are combined to form the plugging portion 213.
