Description

Technical Field

[0001] The utility model relates to the technical field of baby care instruments, in particular to a silent door for a baby incubator. Background Art

[0002] A baby incubator is a care instrument that integrates advanced technologies in clinical medicine, machinery, computer automatic control, sensors and other disciplines, and can provide a premature baby and a sick baby with an excellent environment with purified air, appropriate temperature and humidity, and similar to the mother's uterus. For the convenience of medical staff to operate, a hole through which the arm can reach needs to be provided on the baby incubator, and an operation door and a door lock mechanism (i.e., a door tongue structure) are provided on the hole; the door lock mechanism can keep the operation door in a closed state, and when the operator presses the door tongue on the door lock mechanism, the operation door can be released, so that the operation door can be easily opened.

[0003] The door lock mechanisms for the operation door on traditional baby incubators are mainly divided into three types: bolt-type door locks, rotary blocking door locks and flipping blocking door locks. Although the above three door lock mechanisms are different in structure, the principle is that when the operation door is closed, the door tongue of the door lock mechanism is pushed open, and after the door edge of the operation door passes over the door tongue, the door tongue automatically rebounds to complete the locking action of the operation door; in this process, the operation door is in hard contact with the door tongue (mainly at the bolt), and the rapid collision and the automatic rebound of the door tongue will generate a relatively large noise, which will have an adverse impact on the premature baby or the sick baby in the baby incubator, resulting in an inability to provide a comfortable and quiet cultivation environment for the child. Summary of the Invention

[0004] The purpose of the utility model is to provide a silent door for a baby incubator aiming at the defects of the prior art.

[0005] To achieve the above purpose, the utility model can adopt the following technical solutions:

[0006] The silent door for a baby incubator described in the utility model includes an operation door hinged to the hole of the baby incubator, an elastic torsion spring is sleeved on the hinge shaft at the hinge joint of the operation door and the hole of the baby incubator, and a locking mechanism is arranged on the hole of the baby incubator on the opening and closing side of the operation door; the locking mechanism includes a mounting seat, a door tongue is hinged to the mounting seat through a door lock rotating shaft, a return spring is arranged on the side of the door lock rotating shaft far away from the hole of the baby incubator, the lower end of the return spring is fixed on the mounting seat, the upper end of the return spring pushes the door tongue upward, an installation groove is formed on the door tongue above the return spring, a locking buckle is hinged to the installation groove through a locking buckle rotating shaft, a return torsion spring is sleeved on the locking buckle rotating shaft, the side of the locking buckle close to the hole of the baby incubator is a guiding inclined surface that is inclined outward from top to bottom, and a locking cavity for blocking the door edge on the opening and closing side of the operation door is formed in the installation groove below the locking buckle.

[0007] Furthermore, an elastic shock-absorbing gasket is coated on the outside of the locking buckle to prevent the locking buckle from colliding hard with the operating door, reduce the noise generated when opening and closing the operating door, and reduce the noise generated when the locking buckle rebounds.

[0008] The advantage of the present invention is that by hingedly connecting the door tongue to the mounting base and the locking buckle to the door tongue, the operating door corresponds to different mechanisms during the closing action and the opening action, thereby reducing the torque of the locking buckle that the operating door resists when closing, reducing the collision force of the locking buckle with the door tongue when returning to its position, reducing noise, and providing a more comfortable and quiet incubation environment for premature infants or sick infants in the infant incubator.

[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0013] like Figures 1 - 3 As shown, the silent door of the infant incubator described in the utility model includes an operating door 1 hinged to the door opening of the infant incubator. An elastic torsion spring 2 is installed on the hinge shaft at the hinge between the operating door 1 and the door opening of the infant incubator, which is twisted outward to cause the operating door 1 to bounce open. A locking mechanism is provided on the door opening of the infant incubator on the opening and closing side of the operating door 1 for keeping the operating door 1 open or locked.

[0014] Specifically, the locking mechanism includes a mounting seat 3 fixed to the opening and closing side of the operation door 1 on the opening of the incubator for infants. A door tongue 5 is hinged to the mounting seat 3 through a door lock rotating shaft 4. The axial direction of the door lock rotating shaft 4 is parallel to the axial direction of the hinge shaft at the hinge of the operation door 1. A return spring 6 is arranged on the side of the door lock rotating shaft 4 away from the opening of the incubator for infants. The lower end of the return spring 6 is fixed to the mounting seat 3, and its upper end can upwardly push the door tongue 5, so that the door tongue 5 always has a torsion force for upward rotation. At this time, the bottom surface of the door tongue 5 on the side of the door lock rotating shaft 4 close to the opening of the incubator for infants will abut against the mounting seat 3, forming a limiting end 16 that restricts the overall upward rotation of the door tongue 5, ensuring that the door tongue 5 cannot flip towards the opening side of the incubator for infants and can only flip towards the reverse side of the opening of the incubator for infants when the door tongue 5 is pressed to overcome the elastic force of the return spring 6. In addition, to prevent the return spring 6 from shifting randomly, a positioning column 7 can also be arranged on the mounting seat 3, and a positioning groove 8 adapted to the positioning column 7 is opened on the bottom surface of the door tongue 5, so that the lower end of the return spring 6 is fixedly sleeved on the positioning column 7, and the upper end is clamped in the positioning groove 8, ensuring that the return spring 6 always upwardly pushes the side of the door tongue 5 away from the opening of the incubator for infants.

[0015] An installation groove 9 is opened on the door tongue 5 above the return spring 6. The notch of the installation groove 9 faces the opening side of the incubator for infants, and a locking buckle 11 is hinged in it through a lock buckle rotating shaft 10. Among them, the axial direction of the lock buckle rotating shaft 10 is parallel to the axial direction of the door lock rotating shaft 4, and a return torsion spring 12 for applying an upward rotation torsion force to it is sleeved on the lock buckle rotating shaft 10. The locking buckle 11 is located in the upper part of the cavity of the installation groove 9, and the installation groove 9 below it just forms a locking cavity 13 for clamping the door edge on the opening and closing side of the operation door 1. To ensure that the door edge on the opening and closing side of the operation door 1 can easily slide into the locking cavity 13 during the closing action of the operation door 1, the side of the locking buckle 11 close to the opening of the incubator for infants should also be designed as a guiding inclined surface 14, which inclines from top to bottom towards the opening side of the incubator for infants. When the operation door 1 is in the closing action, the door edge on its opening and closing side first abuts against the guiding inclined surface 14, and then can easily push the locking buckle 11 to rotate downward against the torsion force of the return torsion spring 12, so that the door edge on the opening and closing side of the operation door 1 naturally slides into the locking cavity 13, completing the closing action of the operation door 1.

[0016] Furthermore, to avoid hard collision between the locking buckle 11 and the operation door 1, an elastic shock-absorbing washer 15 should also be wrapped around the outside of the locking buckle 11. Of course, a shock-absorbing cushion layer made of the same material as the elastic shock-absorbing washer 15 can also be fixedly attached to the door edge on the opening and closing side of the operation door 1, so as to reduce the noise generated by the collision with the locking buckle 11 when opening and closing the operation door 1, and at the same time reduce the noise generated when the locking buckle 11 rebounds and resets.

[0017] When performing the closing action, operating door 1 can be closed by only pushing and rotating the locking catch 11, which can reduce the torsion of the locking catch 11 against which the operating door 1 resists during closing, and reduce the collision force between the locking catch 11 and the door tongue 5 when the locking catch 11 returns, thereby achieving the purpose of reducing noise. When performing the opening action, only need to press down the end of the door tongue 5 far from the opening of the incubator, overcoming the upward pushing force of the return spring 6, so that the door tongue 5 together with the locking catch 11 thereon rotates outward with the door lock rotating shaft 4 as the central axis, thus unlocking the operating door 1; once the locking catch 11 crosses the opening and closing side edge of the operating door 1, the operating door 1 will automatically rotate outward and open under the action of the elastic torsion spring 2 sleeved on the hinge shaft at the hinge, easily completing the opening action of the operating door 1. The entire silent door of the incubator enables the operating door 1 to correspond to different mechanisms during the closing action and the opening action, so as to reduce the torsion of the locking catch 11 against which the operating door 1 resists during closing, reduce the collision force between the locking catch 11 and the door tongue 5 when the locking catch 11 returns, reduce noise, and provide a relatively comfortable and quiet cultivation environment for premature infants or sick infants in the incubator.

[0018] In addition, this set of silent door structure of the incubator is also applicable to the operation window of the incubator, only by changing the operating door to an operation window.

[0019] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement conditions, etc. between components in a certain specific posture (as shown in the drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0020] In addition, in the present invention, unless otherwise clearly specified and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be directly connected, or indirectly connected through an intermediate medium, or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
