Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment auxiliary tools, in particular to an auxiliary disassembly and assembly device for a fetal monitoring upper cover. Background Art

[0002] During fetal heart monitoring, in order to monitor the fetal heart rate, a fetal monitoring sensor is used on the mother's belly for sensing monitoring. When the fetal monitoring product is reused, it is necessary to repair the faulty fetal monitoring product and replace the top cover, battery, sensor or other parts of the fetal monitoring product. This requires the use of external tools to assist in disassembling and assembling the top cover of the fetal monitoring body.

[0003] Currently, some tire monitor cover opening / locking tools on the market consist of two parts: a fixed base and a rotating cover. Before opening and locking, the tire monitor device needs to be placed in the fixed base, and the rotating cover needs to be distinguished from the front and back. To open, the rotating cover needs to be snapped into the fixed base and then rotated to open. To lock, the rotating cover needs to be flipped over, with the other side snapped into the fixed base, and then rotated to lock. When the fixed base and rotating cover are snapped together, alignment and positioning are difficult and cumbersome, and the design and production process of the parts are complex and costly.

[0004] Furthermore, currently available cover opening / locking tools are composed of two parts, connected to the tire monitor via a snap-on fastener. The snap-on design and production process are complex, and the development cost of both parts is high. Currently available cover opening / locking tools can only rotate in one direction, not in both directions. When rotating in different directions, the front and back sides must be carefully considered, resulting in cumbersome and inefficient operation. Utility Model Content

[0005] The utility model provides an auxiliary disassembly and assembly device for a tire monitoring cover, aiming to solve the problems of complicated process and inconvenient operation of existing tools for opening and locking the cover.

[0006] The utility model provides an auxiliary disassembly and assembly device for a tire monitor upper cover, which is used for disassembling and assembling the upper cover of a tire monitor main body, comprising a disassembly and assembly shell, a gripping surface being provided on the top of the disassembly and assembly shell, a downward flange being provided on the bottom edge of the disassembly and assembly shell, the disassembly and assembly shell being matched and docked with the upper cover, the flange wrapping the outer edge of the upper cover, an upper cover convex edge being provided at one end of the upper cover, a slot being provided at a position where the flange is aligned with the upper cover convex edge, an unlocking position and a locking position being respectively formed at both ends of the slot, the unlocking position and the locking position being respectively located on both sides of the upper cover convex edge, and the disassembly and assembly shell being rotated so that the unlocking position or the locking position respectively rotates against the upper cover convex edge.

[0007] As a further improvement of the present invention, the unlocking position is provided with a first unlocking position and a second unlocking position, and the first unlocking position and the second unlocking position form a stepped structure. When unlocking, the first unlocking position rotates to contact the upper cover, and the second unlocking position rotates to contact the fetal monitoring body.

[0008] As a further improvement of the present invention, the vertical thickness of the first unlocking position is less than or equal to the thickness of the upper cover.

[0009] As a further improvement of the present invention, the distance of the second unlocking position relative to the first unlocking position in the horizontal direction is greater than or equal to the distance the upper cover rotates relative to the tire monitoring body when unlocked.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figures 1 to 4 As shown, an auxiliary disassembly and assembly device for a tire monitor upper cover of the present invention is used to disassemble and assemble the upper cover 2 of the tire monitor main body 1, including a disassembly and assembly shell 3, a gripping surface is provided on the top of the disassembly and assembly shell 3, a downward flange 4 is provided on the bottom edge of the disassembly and assembly shell 3, the disassembly and assembly shell 3 is matched and docked with the upper cover 2, the flange 4 wraps the outer edge of the upper cover 2, one end of the upper cover 2 is provided with an upper cover convex edge 21, a slot 5 is provided at the position where the flange 4 is aligned with the upper cover convex edge 21, and the flange 4 forms an unlocking position 41 and a locking position 42 at both ends of the slot 5, respectively. The unlocking position 41 and the locking position 42 are respectively located on both sides of the upper cover convex edge 21, and the disassembly and assembly shell 3 is rotated to make the unlocking position 41 or the locking position 42 rotate against the upper cover convex edge 21.

[0026] The bottom and flange 4 of the removable housing 3 form a contact surface with the upper cover 2, forming a wrapping shape. This increases the contact area between the removable housing 3 and the upper cover 2 when gripping and rotating the housing. A slot 5 is designed on the removable housing 3. The removable housing 3 engages the upper cover 2 of the tire monitor body 1 through the slot 5 to push the upper cover 2 for rotation. The unlocking and locking positions 41 and 42 correspond to the positions of contact with the upper cover 2 during unlocking and locking rotations, respectively. Rotating the removable housing 3 in the unlocking direction pushes the upper cover 2 to open it, while rotating the removable housing 3 in the locking direction pushes it to lock it.

[0027] The unlocking latch 41 includes a first unlocking latch 43 and a second unlocking latch 44, which form a stepped structure. During unlocking, the first unlocking latch 43 rotates until it contacts the upper cover 2, and the second unlocking latch 44 rotates until it contacts the fetal monitor body 1. When unlocking and rotating the housing 3, the first unlocking latch 43 first contacts the upper cover 2 and pushes it to rotate relative to the fetal monitor body 1. When the upper cover 2 rotates enough to release the connection with the fetal monitor body 1, the second unlocking latch 44 pushes against the fetal monitor body 1, thereby restricting further movement of the housing 3 and preventing damage to the connection structure caused by excessive rotation of the upper cover 2.

[0028] The vertical thickness of the first unlocking latch 43 is less than or equal to the thickness of the upper cover 2. The thickness of the first unlocking latch 43 is designed to ensure that it just contacts the upper cover 2 without simultaneously contacting the tire monitor body 1. Otherwise, the first unlocking latch 43 would hit the tire monitor body 1, preventing the disassembly housing 3 from further rotation to unlock the upper cover 2.

[0029] The horizontal distance between the second unlocking position 44 and the first unlocking position 43 is greater than or equal to the distance that the upper cover 2 rotates relative to the tire monitoring body 1 when unlocked. This distance ensures that after the upper cover 2 is unlocked, the second unlocking position 44 restricts the disassembly housing 3 from excessive rotation, serving as an unlocking stop.

[0030] The locking latch 42 is provided with a first locking latch 45 and a second locking latch 46. The first locking latch 45 and the second locking latch 46 form a stepped structure. When locked, the first locking latch 45 rotates to contact the upper cover 2, and the second locking latch 46 rotates to contact the fetal monitor body 1. When the housing 3 is rotated for assembly and disassembly, the first locking latch 45 first contacts the upper cover 2 and pushes the upper cover 2 to rotate relative to the fetal monitor body 1. When the upper cover 2 rotates to lock onto the fetal monitor body 1, the second locking latch 46 pushes against the fetal monitor body 1, thereby restricting further movement of the housing 3 and preventing damage to the locking structure between the upper cover 2 and the fetal monitor body 1 caused by excessive rotation of the upper cover 2.

[0031] The vertical thickness of the first locking latch 45 is less than or equal to the thickness of the upper cover 2. The thickness of the first locking latch 45 is designed to ensure that it just contacts the upper cover 2 without simultaneously contacting the fetal monitor body 1. Otherwise, the first locking latch 45 would hit the fetal monitor body 1, preventing the disassembly housing 3 from further rotation to complete the locking of the upper cover 2.

[0032] The horizontal distance between the second locking position 46 and the first locking position 45 is greater than or equal to the distance that the upper cover 2 rotates relative to the fetal monitoring body 1 when locked. This distance ensures that after the upper cover 2 is locked, the second locking position 46 restricts the excessive rotation of the disassembly housing 3, serving as a locking stop.

[0033] The side of the disassembly shell 3 is provided with a protrusion 6. The disassembly shell 3 is designed with two protrusions 6 shape features, the function of which is to meet the need of the hand to better grip the tool and exert better strength when the tool is pushed and rotated, which is very consistent with the human body aesthetic design.

[0034] The middle part of the disassembly shell 3 is provided with a hollow hole 7. A circular hollow feature is designed in the middle position of the disassembly shell 3 to reduce the contact area between the middle position of the disassembly shell 3 and the upper cover 2, which can effectively reduce friction and make the rotation operation easier.

[0035] The bottom of the disassembly shell 3 is provided with a grid-like rib 8. The rib 8 structure with a grid-like weaving feature is designed on the bottom surface of the disassembly shell 3. Its function is to improve the adhesion between the tool and the upper cover 2, prevent the tool from slipping off the upper cover 2 during rotation, and make the operation more stable.

[0036] The top grip surface of the removable housing 3 is etched with a sand-grained process, which effectively reduces fingerprints and stains, while also protecting the housing and facilitating cleaning. The shape, size, and height of the removable housing 3 are designed to mimic the shape of a human hand, providing a very comfortable grip.

[0037] The operating principle of the auxiliary disassembly and assembly device of the tire monitor upper cover is: hold the tire monitor main body 1 with your left hand, hold the disassembly and assembly shell 3 with your right hand and press it in the direction of the tire monitor main body 1, rotate the disassembly and assembly shell 3 in the unlocking direction and push the upper cover 2 to open it, and rotate the disassembly and assembly shell 3 in the locking direction to lock the upper cover 2.

[0038] This utility model designs a tire monitor cover 2 opening / locking tool that is compatible with existing PHILIPS tire monitors and can replace the original Philips tire monitor cover 2 opening / locking tool. It focuses on achieving a simple production process, reduced production costs, and simpler operation. The disassembly shell 3 is composed of a single part and is connected and fixed to the tire monitor body 1 without the use of screws or snaps. The design method is to hold the tire monitor body 1 tightly with one hand and the disassembly shell 3 tightly with the other hand and press it toward the tire monitor body 1. The disassembly shell 3 is rotated to achieve the opening or locking function of the cover 2. The disassembly shell 3 does not need to be distinguished between the front and back sides and can be easily rotated without the aid of any tools, making it easy to operate.

[0039] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
