Description

Technical Field

[0001] The utility model relates to the field of baby carriages, in particular to a detachable connecting mechanism for a baby carriage armrest. Background Art

[0002] A baby stroller is a tool vehicle designed for the convenience of outdoor activities for infants and young children. It has long been widely used. In order to make baby strollers more convenient to carry and store, baby strollers are currently designed to be foldable. In this way, when the baby stroller is not in use, it can be folded into a smaller volume for easy carrying and storage.

[0003] At present, an armrest is installed on the upper front of the seat of a baby stroller. The armrest serves as a grip for the child in the stroller and as a barrier to protect the child in the stroller from falling from the front of the seat. Most of the existing armrests are fixedly installed on the seat of the baby stroller. Since the armrest is a part that children touch more frequently, it is the part of the entire baby stroller that is most likely to get dirty. However, the fixed installation method makes it inconvenient to clean the armrest separately. Children are easily infected by bacteria by touching the relatively dirty armrest, which is very unhygienic and may even make them sick. Therefore, a handrail that can be easily disassembled is needed to meet the demand for the handrail to be disassembled and cleaned at any time. Utility Model Content

Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1 , Figure 1 A diagram of the use state of a detachable connecting mechanism for a baby stroller armrest in the utility model is provided. The detachable connecting mechanism for a baby stroller armrest in the utility model is used to connect a baby stroller armrest 1 and a baby stroller seat 2, and includes an armrest connecting member 10 and a seat connecting member 20. The armrest connecting member 10 is fixedly connected to the baby stroller armrest 1, and the seat connecting member 20 is fixedly connected to the baby stroller seat 2. The armrest connecting member 10 and the seat connecting member 20 are detachably connected. The armrest connecting member 10 and the baby stroller armrest 1, and the seat connecting member 20 and the baby stroller seat 2 can be fixedly connected by common connection methods such as bolt connection or welding, which will not be described one by one here.

[0033] See also Figure 2 The armrest connector 10 is provided with a latch 30 and a spring sheet 40, a lock tongue 50 is installed on the spring sheet 40, and the seat connector 20 is provided with a latch groove 21 matching the latch 30 and a lock tongue hole 22 matching the lock tongue 50. The latch 30 is inserted in the latch groove 21, and the armrest connector 10 can be detachably installed on the seat connector 20 by plugging and pulling out the latch 30. The lock tongue 50 is inserted in the lock tongue hole 22. The lock tongue 50 is stuck in the lock tongue hole 22, so that the armrest connector 10 is locked on the seat connector 20, preventing the armrest 1 from being accidentally pulled up, thereby improving the safety of the baby stroller. The spring sheet 40 can be deformed under the action of external force and then drive the lock tongue 50 to enter the latch groove 21 or drive the lock tongue 50 to disengage from the lock tongue hole 22.

[0034] In some embodiments, the vehicle seat connector 20 can be made of PVC material or one of metal materials, the spring sheet 40 can also be made of PVC material or one of metal materials or other materials that are easily deformed and not easily broken by external forces, and the lock tongue 50 can also be made of PVC material or one of metal materials. In one embodiment, the vehicle seat connector 20 is made of PVC material, the spring sheet 40 is made of aluminum sheet, the lock tongue 50 is made of aluminum block, the spring sheet 40 and the lock tongue 50 are integrally formed, and the top of the spring sheet 40 is fixedly installed on the vehicle seat connector 20 by bolts. In another embodiment, the vehicle seat connector 20, the spring sheet 40 and the lock tongue 50 are all made of PVC material, and the vehicle seat connector 20, the spring sheet 40 and the lock tongue 50 are integrally formed, which is convenient to manufacture and has low manufacturing cost.

[0035] See also Figure 3The armrest connector 10 and the latch 30 are both U-shaped structures, and the two U-shaped arms of the latch 30 are fixedly mounted on the two U-shaped arms of the armrest connector 10 one by one. Specifically, the two U-shaped arms of the armrest connector 10 are both provided with mounting grooves 101 matching the two U-shaped arms of the latch 30, and the two U-shaped arms of the latch 30 are fixedly inserted into the mounting grooves 101 of the two U-shaped arms of the armrest connector 10 one by one. The upper half of the spring sheet 40 is arranged between the two U-shaped arms of the armrest connector 10, and the lower half of the spring sheet 40 is arranged between the two U-shaped arms of the latch 30.

[0036] See also Figure 4 and Figure 8 The spring sheet 40 includes a pressing sheet 401, a first connecting sheet 402 and a second connecting sheet 403. The pressing sheet 401 is located between the two U-shaped arms of the bolt 30. In order to prevent the finger from slipping when pressing the pressing sheet 401, a ridge or protrusion can be provided on the surface of the pressing sheet 401 to increase the friction between the finger and the pressing sheet 401. The locking tongue 50 is fixedly mounted on one side of the second connecting sheet 403, and the locking tongue 50 and the first connecting sheet 402 are located on the same side of the second connecting sheet 403. The first connecting sheet 402, the second connecting sheet 403 and the locking tongue 50 form a "︺" shape. At least a part of the locking tongue 50 extends out between the two U-shaped arms of the bolt 30, and the bottom surface of the locking tongue 50 is an inclined surface.

[0037] See also Figure 4 and Fig. 9 A locking tongue sliding groove 211 matching the locking tongue 50 is provided at a position corresponding to the locking tongue 50 at the notch of the latch slot 21, and the bottom surface of the locking tongue sliding groove 211 is an inclined surface. An inner wall groove 212 matching the second connecting piece 403 is provided on the inner wall of the latch slot 21 opposite to the locking tongue sliding groove 211.

[0038] When installing the armrest, the armrest connector 10 is fixedly installed on the armrest 1, and the seat connector 20 is fixedly installed on the seat 2. Grasp the two sides of the armrest 1 and insert the latch 30 into the corresponding latch groove 21. During the insertion process, when the bottom surface of the lock tongue 50 contacts the seat connector 20 and abuts against the bottom surface of the lock tongue sliding groove 211, continue to press the armrest 1, and the lock tongue 50 slides from the lock tongue sliding groove 211 into the latch groove 21. At this time, the lock tongue 50 abuts against the inner wall of the latch groove 21, and the spring sheet 40 is compressed and deformed by the lock tongue 50. Continue to press the armrest 1 until the lock tongue 50 reaches the lock tongue hole 22. The lock tongue 50 is inserted into the lock tongue hole 22 under the push of the restoring force of the spring sheet 40. At this time, the spring sheet 40 returns to its normal shape, completing the installation and locking of the armrest.

[0039] When removing the armrest, the bottom of the pressing piece 401 on the spring piece 40 is pressed inward, and the pressing piece 40 drives the first connecting piece 401 and the second connecting piece 402 to tilt inward, so that the spring piece 40 is deformed, and the second connecting piece 402 drives the lock tongue 50 to disengage from the lock tongue hole 22, and the armrest 1 is pulled out upward to complete the armrest removal work.

[0040] The utility model provides a detachable connecting mechanism for a baby carriage armrest, which has the following technical effects: the armrest is convenient to disassemble and clean, thereby improving the overall sanitary conditions when using the baby carriage and having strong practicality.

[0041] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
