Description

Technical Field

[0001] The utility model relates to the technical field of baby crib accessories, in particular to a baby crib round tube sliding limit buckle. Background Art

[0002] A crib refers to a bed for infants and young children. There are many different styles of cribs, and their functions and prices vary greatly. When choosing, you should pay attention to the principle of combining safety and practicality. Basically, all cribs will have fences installed on the edge of the bed to prevent the baby from rolling out of the crib when turning over. Most fences are designed to slide up and down, which is convenient for carrying the baby out of the bed. The up and down sliding guardrails require the use of round tube sliding limit buckles to limit the position of the guardrails when they slide.

[0003] The existing crib round tube sliding limit buckle has poor stability after the crib guardrail is fixed, and cannot prevent the crib guardrail from accidentally sliding off when the paddle is accidentally pulled, which greatly reduces safety. Utility Model Content

[0004] In view of the problems in the prior art, the utility model provides a crib round tube sliding limit buckle, which can prevent the limit sleeve from fitting onto the arc-shaped fitting plates on both sides of the sliding groove due to the action of the damping shaft when the paddle is accidentally pulled, thereby achieving limitation and preventing the crib guardrail from accidentally slipping off.

[0005] The technical solution adopted by the utility model to solve the technical problem is a baby crib round tube sliding limit buckle, comprising an arc-shaped bonding plate, a fixed round tube and a movable round tube, the top of the arc-shaped bonding plate is installed with a fixed round tube by screws, a sliding groove is provided on one side of the arc-shaped bonding plate, and limiting holes are provided in the sliding groove at equal distances, a movable round tube is provided on one side of the sliding groove, and a linkage block is installed in the movable round tube through a rotating shaft;

[0006] One end of the linkage block is connected to the bottom of the movable circular tube through a connecting spring, and the other end of the linkage block is installed with a limiting rod through a clamping groove, and the limiting rod passes through the movable circular tube and is clamped in the corresponding limiting hole. The bottom of the linkage block is plugged with a limiting sleeve through a plug-in block, and the limiting sleeve is connected to one side of the bottom of the linkage block through a damping shaft.

[0007] By adopting the above technical solution, when the height of the guardrail needs to be adjusted, the user pulls the dial plate outward, so that the limiting rod at one end of the linkage block squeezes the other end of the connecting spring and disengages from the corresponding limiting hole, so that the movable round tube slides in the sliding groove using the slider, and during the sliding process, the limiting rod is stuck in the corresponding limiting hole to stop sliding;

[0008] Since the plug-in block is specifically made of polyurethane elastomer, it has high elasticity and good toughness. When the paddle plate is pulled, the damping shaft causes the limit sleeve to fit the arc-shaped fitting plates on both sides of the sliding groove to achieve limiting, thereby preventing the crib guardrail from accidentally slipping due to accidental pulling. The paddle plate is continued to be pulled to cause the limit rod to significantly disengage from the limit hole and the limit sleeve to disengage from both sides of the sliding groove, thereby achieving sliding adjustment of the guardrail.

[0009] Specifically, shaft holes are provided on both sides of the movable circular tube, and shaft sleeves are provided on both ends of the rotating shaft and are located in the shaft holes.

[0010] Specifically, the plug-in block is made of polyurethane elastomer, and a paddle is provided on one side of the plug-in block.

[0011] By adopting the above technical solution, since the plug-in block is specifically made of polyurethane elastomer, it has high elasticity and good toughness. When the paddle is pulled, the damping shaft causes the limiting sleeve to fit onto the arc-shaped fitting plates on both sides of the sliding groove to achieve limiting.

[0012] Specifically, a mounting screw hole is provided on one side of the bottom end of the arc-shaped bonding plate, and a plug-in hole is provided on one side of the inner side of the fixed circular tube and close to the arc-shaped bonding plate.

[0013] By adopting the above technical solution, the vertical bar of the guardrail at a corner of the baby crib is attached to one side of the arc-shaped attaching plate and the top end is inserted into the insertion hole, and the matching installation bolts are screwed into the installation screw holes to achieve rapid fixation.

[0014] Specifically, the openings of the fixed circular tube and the movable circular tube are respectively provided with a tube opening overlapping groove A and a tube opening overlapping groove B, and the fixed circular tube and the movable circular tube are both provided with locking screw holes.

[0015] Specifically, a sliding block is provided on one side of the movable circular tube and the sliding block is slidably connected in the sliding groove.

[0016] Beneficial effects of the utility model:

[0017] (1) The utility model discloses a baby crib circular tube sliding limit buckle. When the height of the guardrail needs to be adjusted, the user pulls the dial plate outward, so that the limit rod at the other end of the connecting spring squeezed at one end of the linkage block is disengaged from the corresponding limit hole, thereby allowing the movable circular tube to slide in the sliding groove using the slider. During the sliding process, the limit rod is locked in the corresponding limit hole to stop sliding.

[0018] (2) The utility model discloses a baby crib circular tube sliding limit buckle, wherein the plug-in block is specifically made of polyurethane elastomer, which has high elasticity and good toughness. When the dial plate is pulled, the damping shaft causes the limit sleeve to fit on the arc-shaped fitting plates on both sides of the sliding groove, thereby achieving the limit and preventing the baby crib guardrail from accidentally slipping due to accidental pulling. The dial plate is further pulled to cause the limit rod to significantly disengage from the limit hole and the limit sleeve to disengage from both sides of the sliding groove, thereby achieving the sliding adjustment of the guardrail.

[0026] In order to prevent the crib round tube sliding limit buckle from accidentally pulling the dial plate 16, the damping shaft 18 causes the limit sleeve 17 to fit the arc-shaped fitting plates 6 on both sides of the sliding groove 7 to achieve limit positioning, thereby preventing the crib guardrail from accidentally sliding off. Figure 1-4 As shown, a crib circular tube sliding limit buckle described in the utility model comprises an arc-shaped fitting plate 6, a fixed circular tube 3 and a movable circular tube 9, the top of the arc-shaped fitting plate 6 is mounted with a fixed circular tube 3 by screws, a sliding groove 7 is provided on one side of the arc-shaped fitting plate 6, and limiting holes 12 are provided in the sliding groove 7 at equal distances, a movable circular tube 9 is provided on one side of the sliding groove 7, and a linkage block 15 is installed in the movable circular tube 9 through a rotating shaft 4;

[0027] One end of one side of the linkage block 15 is connected to the bottom of the movable circular tube 9 through a connecting spring 14, and the other end of one side of the linkage block 15 is installed with a limiting rod 20 through a clamping groove, and the limiting rod 20 passes through the movable circular tube 9 and is clamped in the corresponding limiting hole 12, and the bottom of the linkage block 15 is plugged with a limiting sleeve cap 17 through a plug-in block 19, and the limiting sleeve cap 17 is connected to one side of the bottom of the linkage block 15 through a damping shaft 18.

[0028] When the height of the guardrail needs to be adjusted during use, the user pulls the dial plate 16 outward, so that one end of the linkage block 15 squeezes the limiting rod 20 at the other end of the connecting spring 14 and disengages from the corresponding limiting hole 12, so that the movable round tube 9 slides in the sliding groove 7 using the slider 21, and during the sliding process, the limiting rod 20 is locked in the corresponding limiting hole 12 to stop sliding;

[0029] Since the plug-in block 19 is specifically made of polyurethane elastomer, it has high elasticity and good toughness. When the dial plate 16 is pulled, the damping shaft 18 causes the limiting sleeve 17 to fit the arc-shaped fitting plates 6 on both sides of the sliding groove 7 to achieve limiting, thereby preventing the crib guardrail from accidentally slipping due to accidental pulling. The dial plate 16 is continued to be pulled to cause the limiting rod 20 to significantly disengage from the limiting hole 12 and the limiting sleeve 17 to disengage from both sides of the sliding groove 7, thereby achieving sliding adjustment of the guardrail.

[0030] For example, Figure 1 , 3 As shown, the utility model also includes that shaft holes 13 are opened on both sides of the movable circular tube 9 , and shaft sleeves 5 are sleeved on both ends of the rotating shaft 4 and the shaft sleeves 5 are located in the shaft holes 13 .

[0032] For example, Figure 3 As shown, the utility model also includes that the plug-in block 19 is specifically made of polyurethane elastomer, and a dial plate 16 is provided on one side of the plug-in block 19 .

[0033] When in use, since the plug-in block 19 is made of polyurethane elastomer with high elasticity and good toughness, when the paddle 16 is pulled, the damping shaft 18 causes the limiting sleeve 17 to fit the arc-shaped fitting plates 6 on both sides of the sliding groove 7 to achieve limiting.

[0034] For example, Figure 1 , 2 As shown, the utility model also includes that a mounting screw hole 8 is opened on one side of the bottom end of the arc-shaped bonding plate 6, and a plug hole 11 is provided on one side of the inner side of the fixed circular tube 3 and close to the arc-shaped bonding plate 6.

[0038] For example, Figure 1 , 3 As shown, the utility model also includes that a sliding block 21 is provided on one side of the movable circular tube 9 and the sliding block 21 is slidably connected in the sliding groove 7 .

[0039] When in use, the movable round tube 9 is made to slide in the sliding groove 7 by means of the slider 21 , and during the sliding process, the limiting rod 20 is clamped in the corresponding limiting hole 12 to stop sliding.

[0040] When the utility model is used, the vertical bar of the guardrail at a corner of the baby bed is attached to one side of the arc-shaped attaching plate 6 and the top end is inserted into the insertion hole 11, and the matching mounting bolts are screwed into the mounting screw holes 8 to achieve rapid fixing;

[0041] The pipe opening overlap groove A2 and the pipe opening overlap groove B10 are used to facilitate connection with the baby crib guardrail and the matching locking bolt is screwed into the locking screw hole 1 to achieve quick fixation;

[0042] When the height of the guardrail needs to be adjusted, the user pulls the dial plate 16 outward, so that one end of the linkage block 15 squeezes the limiting rod 20 at the other end of the connecting spring 14 and disengages from the corresponding limiting hole 12, so that the movable round tube 9 slides in the sliding groove 7 using the slider 21, and during the sliding process, the limiting rod 20 is locked in the corresponding limiting hole 12 to stop sliding;

[0043] Since the plug-in block 19 is specifically made of polyurethane elastomer, it has high elasticity and good toughness. When the dial plate 16 is pulled, the damping shaft 18 causes the limiting sleeve 17 to fit the arc-shaped fitting plates 6 on both sides of the sliding groove 7 to achieve limiting, thereby preventing the crib guardrail from accidentally slipping due to accidental pulling. The dial plate 16 is continued to be pulled to cause the limiting rod 20 to significantly disengage from the limiting hole 12 and the limiting sleeve 17 to disengage from both sides of the sliding groove 7, thereby achieving sliding adjustment of the guardrail.
