Description
Technical Field
[0001] The utility model relates to the technical field of baby crib guardrails, and more specifically, to a baby crib joint and a baby crib guardrail. Background Art
[0002] A crib guardrail is a protective device installed on the edge of a crib to prevent the baby from rolling off or climbing out of the crib and to protect the baby from accidental injuries. Common crib guardrails are made of plastic, metal and wood and are usually retractable, foldable and easy to install, making them convenient for parents to use and store.
[0003] However, the guardrails on baby cribs are usually set high to prevent the baby from climbing out of the crib, and the guardrails of the baby crib usually need to be folded easily to facilitate the baby to be taken out after folding. The folding joints of the guardrails are usually locked by buckles, and the buckles are often reset by springs. When folding is required, it is necessary to unlock it manually. However, since a spring is required for reset, it is necessary to press it manually to avoid the problem of affecting the folding caused by the spring reset. However, there are often more than one buckle on the guardrail. If one position is pressed all the time, it will be difficult to unlock the other position of the guardrail, resulting in the problem that two or more people need to operate at the same time, which is inconvenient to operate.

[0023] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.
[0024] Refer to the instruction manual Figures 1 to 3 A crib joint comprises: a joint 1, a joint 2 2 is rotatably arranged on one side of the joint 1, a sliding groove 21 is provided on the joint 2, and a locking component 3 is arranged in the sliding groove 21;
[0025] The locking assembly 3 includes a button 31, a pin 32 and an elastic member 33. The button 31 is slidably arranged in the sliding groove 21. The pin 32 is installed on the button 31. The elastic member 33 is arranged at the bottom of the button 31. A sliding cavity 211 is provided on the side wall of the sliding groove 21. A sliding groove 11 is provided on the side wall of the joint 1. One end of the pin 32 slides inside the sliding cavity 211 and the sliding groove 11. The sliding groove 11 includes a groove 111 and a groove 2 112. When the pin 32 is located in the groove 111, the joint 1 and the joint 2 are in a locked state. When the pin 32 is located in the groove 112, the joint 1 and the joint 2 are in an unlocked state.
[0026] The joint 2 is also provided with a clamping assembly 4 , and when the button 31 is pressed, the clamping assembly 4 is used to lock the pin 32 .
[0027] It should be noted that the elastic member 33 is a spring. When folded, by pressing the button 31, the button 31 squeezes the spring and locks the pin 32 through the snap-fit assembly 4. At this time, the pin 32 is in the groove 2 112, and the joint 1 and the joint 2 are in an unlocked state. At this time, the pin 32 is in a locked state, which is convenient for unlocking the joints of other parts after the joints of this part are unlocked. Under the action of the spring, it will not cause the need for manual pressing all the time. There is no need for multiple people to operate, and one person can operate it in sequence.
[0028] For further information, please refer to the attached manual. Figure 2 The clamping assembly 4 includes a pin hook 41 and an elastic member 42. The pin hook 41 is rotatably arranged on the joint 2. A side groove 22 is provided on one side of the joint 2. The pin hook 41 is located in the side groove 22. The elastic member 42 is arranged in the side groove 22 for resetting the pin hook 41.
[0029] It should be noted that the elastic member 42 is a torsion spring. After pressing the button 31, it can drive the pin 32 to squeeze the pin hook 41, so that the pin hook 41 rotates. When the pin 32 moves into the second slot 112, under the elastic action of the torsion spring, the pin hook 41 resets and clamps the pin 32 to position the pin 32, thereby preventing the button 31 from directly resetting under the action of the spring.
[0030] For further information, please refer to the attached manual. Figure 2 A limit block 411 is provided on one side of the pin hook 41, and a limit slot 12 is provided on the side wall of the joint 1, and the limit block 411 is slidably arranged in the limit slot 12, referring to the attached manual Figures 4 to 6 The groove 111 is arranged in a straight line, and the width of the groove 111 is the same as the diameter of the pin 32 , and the groove 2 112 is arranged in a semi-arc shape, and the width of the groove 2 112 is greater than the diameter of the pin 32 .
[0031] It should be noted that the limit groove 12 is set as an arc track. After the joint 1 and the joint 2 are unlocked, the joint 2 is rotated. During the rotation of the joint 2, the pin hook 41 and the pin 32 can be driven to rotate synchronously. At this time, the limit block 411 can slide in the limit groove 12. Figure 5 As shown, when one end of the limiting block 411 abuts against the inner wall of the limiting groove 12, the joint 2 continues to rotate, the pin hook 41 stops rotating, and the pin 32 continues to rotate. Since the pin 32 is in the second groove 112 at this time, the width of the second groove 112 is greater than the diameter of the pin 32, which can provide a movable space for the pin 32, so that the pin 32 can slide out of the pin hook 41 under the action of the spring and abut against the inner wall of the second groove 112, so that the positioning of the pin 32 can be released. Figure 6As shown, when joint 2 needs to be reset, the pin 32 contacts the pin hook 41, and the joint 2 can be reset and rotated. After the joint 2 is reset, the pin 32 can be reset to the groove 111 under the action of the spring, so that after the joint 2 is reset, the button 31 and the pin 32 can be automatically reset to achieve automatic locking between joint 1 and joint 2.
[0032] For details, please refer to the attached manual. Figure 7 A baby crib guardrail includes a guardrail body 5, the guardrail body 5 includes a side bracket 51, a base frame 52 is installed on the side of the side bracket 51, a branch pipe 1 53 is installed on the top of the side bracket 51, a joint 1 is installed on the branch pipe 1 53, a branch pipe 2 54 is installed on the joint 2, and a side rail 55 is installed on the branch pipe 2 54.
[0033] It should be noted that the crib guardrail includes two joints, and branch pipe one 53 and branch pipe two 54 are used to connect the joints. When folding, the locks of the joints can be adjusted in sequence, and then the side rails 55 can be folded so that the guardrail body 5 can be folded under the action of the joints, which makes it convenient to take the baby out after folding. After taking the baby out, the side rails 55 are reset, and the guardrail body 5 can be automatically locked when reset under the action of the joints.
[0034] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
