Description

Technical Field

[0001] This utility model relates to the field of hospital infusion and curtain track, and in particular to a track corner component. Background Technology

[0002] To facilitate the hanging of IV poles or curtains, hospitals typically install IV or curtain tracks in the ceiling. Rollers are installed within the tracks, and the IV pole or curtain is fixed below the rollers. The position of the IV pole or the opening and closing of the curtain is achieved by the sliding of the rollers within the tracks.

[0003] The infusion and curtain track consists of three parts: the X-axis track, the Y-axis track, and track corner components. The X-axis and Y-axis tracks have identical structures, the difference being that one allows the rollers to move along the X-axis, while the other allows them to move along the Y-axis. The track corner components facilitate a smooth transition of the rollers from the X-axis to the Y-axis or vice versa. Existing tracks are of two types: single-suspension tracks (such as...) Figure 1 (as shown) and double-suspension tracks (as shown) Figure 2 (As shown). Existing track corner fittings are divided into four types: 1. Enabling operation in both the X and Y axes; 2. Ensuring operation in both the X and Y axes while adding an X-axis interface or a Y-axis interface to achieve three-way connection; 3. Ensuring operation in both the X and Y axes while simultaneously adding an X-axis interface and a Y-axis interface to achieve four-way connection. To accommodate single-suspension and double-suspension tracks, the existing four structures of the track corner fittings are further divided into two types: a single-plug interface for single-suspension tracks and a double-plug interface for double-suspension tracks.

[0004] Because there are two types of tracks and eight types of track corner fittings, production and inventory costs remain consistently high. Furthermore, the applicant has observed during actual installations that installers frequently use a grinder to cut off the X-axis or Y-axis interfaces (or both) of the four-interface track corner fittings used for directional expansion. This method wastes materials and results in low installation efficiency.

[0005] How to reduce production costs, inventory costs, and installation costs by changing the structure of the track corner components is the issue that the applicant in this case is committed to solving. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model provides a track corner component.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a track corner component, wherein the lower part of the track corner component is provided with an arc-shaped pulley cavity for the pulley to turn 90 degrees; the track corner component has an interface one for locking and fixing the track at the port in the X-axis direction; the track corner component has an interface two for locking and fixing the track at the port in the Y-axis direction; characterized in that, one interface has a plug interface one that cooperates with the T-shaped suspension arm of the single suspension part; one interface has a plug interface two that cooperates with the double T-shaped suspension arm of the double suspension part; the two plug interfaces of the plug interface two are symmetrically arranged on both sides of the plug interface one; the plug interface two adopts the same plug interface one and plug interface two as the interface one; the right angle of the track corner component is provided with a mounting groove for fixing the expansion interface; the expansion interface is detachably fixed at the mounting groove to realize the track corner component to expand unidirectionally in the X-axis direction or unidirectionally in the Y-axis direction or simultaneously in both the X-axis and Y-axis directions; the expansion interface adopts the same plug interface one and plug interface two as the interface one.

[0008] After adopting the above method, it is compatible with single-suspension tracks via connector one and with double-suspension tracks via connector two. Expansion interfaces allow for expansion in only the X-axis direction, only the Y-axis direction, or both directions simultaneously. Alternatively, expansion can be avoided by not installing the expansion interfaces. This integrates the original eight track corner components into one, reducing mold development costs from a production perspective and reducing inventory pressure from an inventory perspective. It also improves installation efficiency.

[0009] Further improvements include: the width of the first insertion interface is the same as the width of the vertical plate of the single suspension unit; the height of the second insertion interface is equal to the distance from the bottom surface of the horizontal plate of the double suspension unit to the top surface of the vertical plate; the width of the insertion interface of the second insertion interface is the same as the width of the vertical plate of the double suspension unit; and the height of the second insertion interface is equal to the distance from the bottom surface of the horizontal plate of the double suspension unit to the top surface of the vertical plate. This mutual cooperation achieves a fixed connection after insertion.

[0010] Further improvements include expansion interfaces: single-interface and dual-interface. The single-interface includes a fixing part and interface three; interface three uses the same structure as interface one, insert interface one and insert interface two. The dual-interface includes a fixing part and two vertically distributed interfaces four; interface four uses the same structure as interface one, insert interface one and insert interface two. When expansion is needed in the X-axis or Y-axis direction, the single-interface can be expanded along the X-axis or Y-axis direction on the mounting slot. When expansion is needed in the X-axis or Y-axis direction, the dual-interface can be fixed on the mounting slot.

[0011] A further improvement involves providing a through hole on the fixing part; a threaded hole corresponding to the through hole is provided in the mounting groove; the fixing part is secured to the mounting groove by a screw passing through the through hole and engaging with the threaded hole. This screw-fixing method is convenient, quick, and cost-effective.

[0012] Further improvements include an upper limit post in the mounting slot; the two side walls of the fixing part of the expansion interface abut against the upper limit post and the side wall of the mounting slot, respectively; the upper limit post is used to limit the deflection of the expansion interface. The upper limit post effectively blocks and limits any possible deflection of the expansion interface, ensuring stability when connected to the track.

[0013] Further improvements include an arc-shaped maintenance window above the track corner component; the two ends of the arc-shaped maintenance window extend to interface one and interface two respectively; an arc-shaped cover plate matching the shape of the arc-shaped maintenance window is detachably fixed to the arc-shaped maintenance window; the arc-shaped cover plate is used to completely cover the arc-shaped maintenance window. The arc-shaped maintenance window allows for cleaning and maintenance of the interior of the arc-shaped pulley cavity, ensuring smooth rotation of the rollers. The arc-shaped cover plate prevents dust and other substances from entering the pulley cavity and causing unnecessary damage.

[0014] Further improvements include a mounting slot at the curved maintenance window; the curved cover plate is fixed in the slot with screws; and the upper surface of the curved maintenance window and the upper surface of the curved cover plate are on the same plane. This ensures the product's aesthetic appeal.

[0015] A further improvement is the addition of a support surface extending outwards from the bottom of the track corner piece to support the ceiling. This support surface can be directly used to support the ceiling, eliminating the need for separately manufactured accessories to support the ceiling.

[0016] Further improvements include symmetrical limit blocks located below both interface one and interface two; these limit blocks abut against the outer wall of the track to prevent it from deflecting. The design of these limit blocks effectively prevents the track from deflecting to either side. Attached Figure Description

[0022] The preferred embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figures 3 to 5As shown, a track corner fitting has an arc-shaped pulley cavity 1 at its bottom, allowing the pulley to turn 90 degrees; a support surface 20 for supporting the ceiling extends outward from the bottom surface of the track corner fitting. The track corner fitting has an interface 2 at its X-axis end for engaging and fixing the track; and an interface 3 at its Y-axis end for engaging and fixing the track; symmetrical limiting blocks 21 are provided below both interfaces 1 and 2; these limiting blocks abut against the outer wall of the track to prevent deflection. An arc-shaped maintenance window 17 is provided above the track corner fitting; the two ends of the arc-shaped maintenance window extend to interfaces 1 and 2 respectively; an arc-shaped cover 18, matching the shape of the arc-shaped maintenance window, is detachably fixed to the arc-shaped maintenance window; the arc-shaped cover completely covers the arc-shaped maintenance window. The curved maintenance window is provided with a mounting slot 19; the curved cover plate is fixed in the slot with screws; the upper surface of the curved maintenance window and the upper surface of the curved cover plate are on the same plane.

[0024] One interface is provided with a first interface 4 that mates with the T-shaped suspension arm of the single suspension unit; another interface is provided with a second interface 5 that mates with the double T-shaped suspension arm of the double suspension unit; the two interfaces of the second interface are symmetrically arranged on both sides of the first interface; the second interface adopts the same structure as the first interface, the first interface and the second interface; the right angle of the track corner piece is provided with a mounting groove 6 for fixing the expansion interface; the upper limit post 16 of the mounting groove; the two side walls of the fixing part of the expansion interface abut against the side walls of the limit post and the mounting groove, respectively; the limit post is used to limit the deflection of the expansion interface.

[0025] The expansion interface is detachably fixed to the mounting slot to enable unidirectional expansion of the track corner component in the X-axis direction, unidirectional expansion in the Y-axis direction, or bidirectional expansion in both the X-axis and Y-axis directions simultaneously. The expansion interface uses plug-in interface one and plug-in interface two, which have the same structure as interface one. The width of plug-in interface one is the same as the width of the vertical plate 7 of the single suspension part; the height of plug-in interface one is equal to the distance from the bottom surface of the horizontal plate 8 of the single suspension part to the top surface of the vertical plate. The width of plug-in interface two is the same as the width of the vertical plate of the double suspension part; the height of plug-in interface two is equal to the distance from the bottom surface of the horizontal plate of the double suspension part to the top surface of the vertical plate.

[0026] The expansion interface includes a single interface 9 and a dual interface 10; the single interface includes a fixing part 11 and an interface three 12; the interface three adopts the same structure as interface one, using plug-in interface one and plug-in interface two; the dual interface includes a fixing part and two vertically distributed interfaces four 13; the interfaces four adopt the same structure as interface one, using plug-in interface one and plug-in interface two. The fixing part is provided with a through hole 14; the mounting groove is provided with a threaded hole 15 corresponding to the through hole; the fixing part is fixed to the mounting groove by screws passing through the through hole and engaging with the threaded hole.

[0027] To better illustrate the technical solution of this application, the use of the track corner component will now be further explained.

[0028] When using a single-suspension rail, insert the T-shaped suspension arm of the rail into connector one. Since the width of connector one is the same as the width of the vertical plate of the T-shaped suspension arm, and the height of connector one is the same as the distance from the bottom surface of the horizontal plate of the T-shaped suspension arm to the top surface of the rail, full insertion allows for a secure connection between the rail and the rail corner fittings through mutual cooperation. The rail fixing method for a double-suspension rail is the same as for a single-suspension rail and will not be described further.

[0029] When expansion along the X or Y axis is required, a single interface can be fixed in the mounting slot with screws to allow the track corner component to expand in either the X or Y axis direction. When expansion along both the X and Y axes is required simultaneously, a dual interface can be fixed in the mounting slot with screws to allow the track corner component to expand in either the X or Y axis direction at the same time.

[0030] By adopting the above method, the original eight designs for track corner components—including those for single-suspension tracks (no extension, X-axis extension, Y-axis extension, and simultaneous X-axis and Y-axis extension), double-suspension tracks (no extension, X-axis extension, Y-axis extension, and simultaneous X-axis and Y-axis extension), and single-suspension tracks (no extension, X-axis extension, Y-axis extension, and simultaneous X-axis and Y-axis extension)—have been streamlined into a single design. This achieves cost reduction and efficiency improvement across all three stages: processing, warehousing, and installation, while also significantly enhancing installation efficiency.

[0031] The above embodiments are merely preferred embodiments of this utility model, but this embodiment is not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of this utility model shall be considered equivalent substitutions and shall fall within the protection scope of this utility model.
