Description

Technical Field

[0001] This utility model relates to the field of motion coordination technology for medical housings, specifically a mechanical motion limiting structure between composite material housings of medical devices. Background Technology

[0002] There is relative movement between the outer shells of this medical device. The upper part is fixed and stationary, while the lower part rotates. The resin-based composite material is prone to deformation, and it is impossible to guarantee that there will be no scratches or bumps during the movement of the outer shells. Scratches and bumps between the outer shells during movement affect the aesthetics of the outer shell assembly, affect the patient's mentality, and thus lead to inaccurate test data.

[0003] Existing methods mainly rely on the selection of more expensive raw materials. However, due to the inherent characteristics of resin-based composite materials, deformation still occurs, resulting in relatively complex internal structures. These overly complex structures significantly increase the risk of maintenance.

[0004] To eliminate the adverse effects of movement of medical device housings, we propose a mechanical movement limiting structure between composite material housings of medical devices. Utility Model Content

[0005] The purpose of this invention is to provide a mechanical movement limiting structure between composite material shells of medical devices, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mechanical motion limiting structure between composite material shells of medical devices, including a rotating lower shell, an upper stationary product connected inside the rotating lower shell, and a rotating limiting component disposed inside the rotating lower shell, wherein an anti-detachment component is disposed inside the rotating limiting component.

[0007] Preferably, the rotation limiting component includes an adhesive positioning fixture disposed above the rotating lower shell, a guide plate disposed on the outside of the upper stationary product, a guide plate disposed above the guide plate, and an internal hexagon countersunk screw sleeved inside the guide plate.

[0008] Preferably, the anti-detachment component includes a mounting hole formed on the top surface of the guide sliding pressure plate, a limiting groove formed on the inner wall of the mounting hole, a first magnetic plate fixedly installed inside the limiting groove, a second magnetic plate slidably arranged inside the limiting groove, and an anti-detachment ring fixedly installed on the outer wall of the second magnetic plate.

[0009] Preferably, the guide plate is made of POM material, and the guide pressure plate is made of galvanized carbon steel sheet, which improves the sliding performance under their constraints.

[0010] Preferably, the outer walls of the guide plate and the guide pressure plate are provided with slots, and the guide plate and the guide pressure plate are connected by countersunk hexagon screws. Under their constraint, the guide plate and the guide pressure plate can be quickly combined.

[0011] Preferably, the anti-loosening ring is made of a non-slip material and is sleeved on the outer wall of the internal hexagon countersunk screw. The non-slip material of the anti-loosening ring can increase its friction coefficient with the internal hexagon countersunk screw, thus preventing the internal hexagon countersunk screw from falling off.

[0012] Preferably, the second magnetic plate and the first magnetic plate are magnetically repelled, and the second magnetic plate and the first magnetic plate are arranged in parallel. Under the restriction of magnetic repulsion, the anti-loosening ring can be pushed upward, so that the anti-loosening ring pushes the internal hexagon countersunk screw, so that the outer thread of the internal hexagon countersunk screw is locked with the mounting hole, thus preventing the internal hexagon countersunk screw from loosening.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The mechanical motion limiting structure between the composite material shells of this medical device uses a rotation limiting component bonded to the upper stationary product via structural adhesive. After assembly, the rotating lower shell and the parts have a certain overlap distance. During movement, the rotating lower shell rotates along the central axis, while the upper stationary product remains stationary. Rotation is limited by the rotation limiting component, which mainly consists of a guide plate, a guide pressure plate, and countersunk head hexagon screws. The guide plate is made of POM material and machined. POM has excellent guiding performance, but its surface tension is high, resulting in poor adhesion. Therefore, the guide pressure plate is made of galvanized carbon steel. The guide plate and guide pressure plate are combined using countersunk head hexagon screws and then bonded to the upper stationary product. After prolonged use, when the guide plate wears out, the countersunk head hexagon screws are removed, and the guide plate is replaced. During product rotation, even if the moving parts deform, the deformation can be corrected by the support of the rotation limiting component. Furthermore, due to… The rotating limiting component uses POM material, ensuring that even if scratches occur during rotation, there will be no noise, guaranteeing a better experience for patients during treatment. Furthermore, the rotating limiting component corrects product deformation, ensuring the product's aesthetic appearance. It also facilitates on-site replacement after prolonged wear. This structure can be used in similar medical devices, significantly reducing the difficulty of product manufacturing. Using an adhesive positioning fixture, six lines are marked on the product. After marking, the adhesive positioning fixture is removed. Guide plates and countersunk hexagonal screws are then fabricated. The two guide plates and the guide plate are installed together using countersunk hexagonal screws. The rotating limiting component is positioned and bonded according to the marked positions. Note that only the guide plate is bonded. The thickness is controlled during bonding; the thickness is the movement gap between the rotating lower shell and the upper stationary product. During installation, the rotating lower shell is first installed on the device, followed by the upper stationary product. After installation, the device can be rotated for relevant testing.

[0015] 2. The mechanical movement limiting structure between the composite material shells of this medical device, when the hexagonal countersunk screw is needed to connect the guide plate and the guide slide, prevents the hexagonal countersunk screw from loosening. An anti-loosening component prevents the hexagonal countersunk screw from loosening. When the hexagonal countersunk screw is installed into the mounting hole, it contacts and presses against the anti-loosening ring, causing the second magnetic plate fixedly mounted on the outer wall of the anti-loosening ring to slide within the limiting groove. This causes the second magnetic plate to slide towards the first magnetic plate. Due to the magnetic repulsion between the first and second magnetic plates, the second magnetic plate is pushed upwards, applying a thrust to the hexagonal countersunk screw and the mounting hole, making the connection between the hexagonal countersunk screw and the mounting hole more secure. Because the anti-loosening ring is made of anti-slip material, it increases the coefficient of friction between the hexagonal countersunk screw and the anti-loosening ring, thus achieving an anti-loosening effect.

Detailed Implementation

[0022] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0023] Example 1: A preferred embodiment of the mechanical movement limiting structure between composite material shells of medical devices provided by this utility model. Figures 1 to 5 As shown: A mechanical motion limiting structure between composite material shells of a medical device, including a rotating lower shell 1;

[0024] The upper stationary product 3 is connected inside the rotating lower shell 1;

[0025] And a rotation limiting component 2 is provided inside the rotating lower shell 1. The rotation limiting component 2 includes an adhesive positioning fixture 4 provided above the rotating lower shell 1. A guide plate 21 is provided outside the upper stationary product 3. A guide plate 22 is provided above the guide plate 21. An internal hexagon countersunk screw 23 is sleeved inside the guide plate 22.

[0026] In this embodiment, the rotation limiting component 2 is bonded to the upper stationary product 3 with structural adhesive. After assembly, the rotating lower shell 1 and the parts have a certain overlap distance. During movement, the rotating lower shell 1 rotates along the central axis, while the upper stationary product 3 remains stationary. The rotation is limited by the rotation limiting component 2. The rotation limiting component 2 mainly consists of a guide plate 21, a guide pressure plate 22, and a countersunk head screw 23. The guide plate 21 is made of POM material and machined. POM has excellent guiding performance, but its surface tension is relatively high, so its adhesion is poor. Therefore, the guide pressure plate 22 is made of galvanized carbon steel. The guide plate 21 and the guide pressure plate 22 are combined using countersunk head screws 23 and then bonded to the upper stationary product 3. After long-term use, when the guide plate 21 wears out, the countersunk head screws 23 are removed and the guide plate 21 is replaced. During the product rotation process, even if the moving parts deform, the deformed product can be corrected by the support of the rotation limiting component 2. At the same time, due to the rotation limiting... Component 2 is made of POM material, ensuring that even if scratches occur during rotation, there will be no noise, thus guaranteeing a better experience for patients during treatment. Furthermore, the rotation limiting component 2 corrects product deformation, ensuring the product's aesthetic appearance. It also facilitates on-site replacement after prolonged wear. This structure can be used for similar medical devices, greatly reducing the difficulty of product manufacturing. Using the adhesive positioning fixture 4, six lines are marked on the product. After marking, the adhesive positioning fixture 4 is removed. Guide plates 21 and countersunk hexagon screws 23 are then fabricated. The two guide plates 21 and guide plate 22 are installed together using countersunk hexagon screws 23. The rotation limiting component 2 is positioned and bonded according to the marked positions. Note that only the guide plate 22 is bonded. The thickness is controlled during bonding; the thickness is the movement gap between the rotating lower shell 1 and the upper stationary product 3. During installation, the rotating lower shell 1 is first installed on the device, and then the upper stationary product 3 is installed. After installation, the device can be rotated for relevant testing.

[0027] Furthermore, the guide plate 21 is made of POM material, and the guide pressure plate 22 is made of galvanized carbon steel sheet, which makes the sliding performance better under their constraints.

[0028] Furthermore, the outer walls of the guide plate 21 and the guide pressure plate 22 are provided with holes and slots. The guide plate 21 and the guide pressure plate 22 are connected by internal hexagon countersunk screws 23. Under their constraint, the guide plate 21 and the guide pressure plate 22 can be quickly combined.

[0029] Example 2: Based on Example 1, a preferred embodiment of the mechanical motion limiting structure between composite material shells of medical devices provided by this utility model is as follows: Figures 1 to 5 As shown: The anti-detachment component 5 includes a mounting hole 51 opened on the top surface of the guide sliding pressure plate 22. A limiting groove 52 is opened on the inner wall of the mounting hole 51. A first magnetic plate 53 is fixedly installed inside the limiting groove 52. A second magnetic plate 54 is slidably arranged inside the limiting groove 52. An anti-detachment ring 55 is fixedly installed on the outer wall of the second magnetic plate 54.

[0030] In this embodiment, when the countersunk head screw 23 is needed to connect the guide plate 22 and the guide slide plate 21, to prevent the countersunk head screw 23 from loosening, the anti-loosening component 5 can be used to prevent the countersunk head screw 23 from loosening. When the countersunk head screw 23 is installed into the mounting hole 51, the countersunk head screw 23 contacts and presses against the anti-loosening ring 55, causing the second magnetic plate 54, which is fixedly installed on the outer wall of the anti-loosening ring 55, to slide inside the limiting groove 52, so that the second magnetic plate 54... The plate 54 slides towards the first magnetic plate 53. Since the first magnetic plate 53 and the second magnetic plate 54 are magnetically repelled, the second magnetic plate 54 can be pushed upward under its constraint, which applies a thrust to the interior of the hexagon countersunk screw 23 and the mounting hole 51, making the connection between the hexagon countersunk screw 23 and the mounting hole 51 more secure. Since the anti-slip ring 55 is made of anti-slip material, it can increase the friction coefficient between the hexagon countersunk screw 23 and the anti-slip ring 55, so as to achieve the anti-loosening effect of the hexagon countersunk screw 23.

[0031] Furthermore, the anti-slip ring 55 is made of anti-slip material and is fitted onto the outer wall of the internal hexagon countersunk screw 23. The anti-slip material of the anti-slip ring 55 can increase the friction coefficient between it and the internal hexagon countersunk screw 23, thus preventing the internal hexagon countersunk screw 23 from falling off.

[0032] In addition, the second magnetic plate 54 and the first magnetic plate 53 are magnetically repulsive. The second magnetic plate 54 and the first magnetic plate 53 are arranged in parallel. Under the restriction of magnetic repulsion, the anti-loosening ring 55 can be pushed upward, so that the anti-loosening ring 55 pushes the internal hexagon countersunk screw 23, so that the outer thread of the internal hexagon countersunk screw 23 is locked with the mounting hole 51, thus preventing the internal hexagon countersunk screw 23 from loosening.

[0033] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
