Description

Technical Field

[0001] This utility model relates to the field of door and window technology, specifically to a sliding door track closure device. Background Technology

[0002] PD doors, also known as PT doors, are doors that can be both pushed and pulled or opened. The design concept originated in Singapore and has become very popular in China in recent years. PT doors completely overcome the limitation of traditional sliding doors that can only be opened halfway. They are mainly used in kitchens, living rooms, balconies, and shop entrances, offering advantages such as easy opening, large space utilization, aesthetics, and durability, making them highly favored by consumers.

[0003] The sliding track of the PT door consists of two parts: a fixed track fixed to the upper part of the door frame and a moving track fixed to the top of the hinged door leaf. The ends of the moving track and the fixed track are equipped with a closing device that can be connected to each other, allowing the sliding door leaf to slide between the fixed track and the moving track. When it is necessary to fully open, the sliding door leaf needs to slide to the moving track with the help of the fixed track and the closing device, overlap with the hinged door leaf, and then rotate outward to open.

[0004] In existing technology, both the fixed and moving parts of the door closer have the same pulley cavity structure as the fixed and moving tracks, allowing the pulley at the top of the sliding door to slide through when the fixed and moving parts are engaged. However, the connection between the fixed and moving parts of the door closer is a beveled joint, requiring a certain gap for the swing door to open. This causes the pulley at the top of the sliding door to vibrate when passing through the gap, affecting the smoothness of the sliding door and reducing the user experience. Utility Model Content

[0005] The purpose of this utility model is to provide a sliding door track closer, which aims to solve the problem in the prior art where there is a gap after the fixed part and the moving part of the closer are connected, causing the pulley at the top of the sliding door to vibrate when passing through the gap.

[0006] To achieve the above objectives, this utility model provides a sliding door track closure device, including a movable part and a fixed part for cooperative use. Both the movable part and the fixed part have internal pulley mounting cavities that communicate with each other when engaged. The bottom of each pulley mounting cavity is provided with a pulley track. The movable part has a first extension at the end of the pulley track; the fixed part has a second extension at the end of the pulley track. The first extension and the second extension form a splicing track when engaged, and the splicing track is connected to the pulley track.

[0007] Furthermore, the end faces of the pulley tracks on the moving part and the fixed part that cooperate with each other are inclined surfaces that are inclined in the same direction, and the end faces of the first extension and the second extension are inclined surfaces that are inclined in the same direction.

[0008] Furthermore, the first extension and the pulley track on the movable part are integrally formed.

[0009] Furthermore, the second extension and the pulley track on the fixed part are integrally formed.

[0010] Furthermore, the widths of the first extension and the second extension are smaller than the width of the pulley track.

[0011] Furthermore, the movable part is provided with a locking block on one side of the pulley mounting cavity, and the fixed part is provided with a locking member that cooperates with the locking block on one side of the pulley mounting cavity.

[0012] Furthermore, the outer end face of the moving part is provided with a first closed baffle, and the outer end face of the fixed part is provided with a second closed baffle. When the moving part and the fixed part are engaged and connected, the first closed baffle and the second closed baffle are arranged opposite to each other.

[0013] Furthermore, the moving part and the fixed part are provided with screw connection holes for connecting with the profile.

[0014] This utility model provides a sliding door track closer, which, compared to existing technologies, completely fills the gap between the fixed and moving parts by setting a first extension and a second extension to form a continuous spliced ​​track. When the sliding door pulley passes through the closer, the spliced ​​track and the pulley track form a continuous guide surface without breaks, effectively avoiding longitudinal displacement and lateral shaking caused when the pulley passes through the gap, and significantly improving the stability and smoothness of the door sliding process.

[0022] The present invention will be described in detail below with reference to specific embodiments.

[0023] In this utility model, when directional terms appear, they are used to facilitate the description of this utility model and simplify the description, rather than indicating or implying that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this utility model.

[0024] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] like Figures 1 to 3 As shown, a sliding door track closure includes a movable part 10 and a fixed part 20 used in conjunction. The movable part 10 and the fixed part 20 are both provided with pulley mounting cavities 30 that are communicative when they are in conjunction. The bottom of the pulley mounting cavity 30 is provided with a pulley track 31.

[0026] The movable part 10 is provided with a first extension 11 at the end of the pulley track, and the fixed part 20 is provided with a second extension 21 at the end of the pulley track. When the first extension 11 and the second extension 21 are engaged, they form a spliced ​​track, which is connected to the pulley track 31.

[0027] In practical implementation, the moving part 10 is installed at the port of the moving track profile at the top of the hinged door leaf, and the fixed part 20 is installed at the port of the fixed track profile at the top of the door frame. The moving part 10 moves with the hinged door leaf as it opens. When the hinged door leaf is closed, the moving part 10 and the fixed part 20 engage and connect, forming a continuous splicing track with the pulley track 31 through the first extension part 11 and the second extension part 21, filling the gap in the fit between the fixed part 20 and the moving part 10. When the pulley of the sliding door leaf passes the closure device, the splicing track and the pulley track 31 form a continuous guide surface without breaks, effectively avoiding longitudinal displacement and lateral shaking caused when the pulley passes through the gap, significantly improving the stability and smoothness of the door leaf pushing and pulling process.

[0028] In this embodiment, the end faces of the pulley tracks 31 on the moving part 10 and the fixed part 20 that cooperate with each other are inclined surfaces that are inclined in the same direction, and the end faces of the first extension 11 and the second extension 21 are inclined surfaces that are inclined in the same direction.

[0029] In practical implementation, the end faces of the pulley tracks 31 on the moving part 10 and the fixed part 20 are relatively fitted inclined surfaces, and the end faces of the first extension part 11 and the second extension part 21 are relatively fitted inclined surfaces, so that the swing door can effectively complete the swing opening action without causing structural obstruction.

[0030] In this embodiment, the first extension 11 and the pulley track 31 on the moving part 10 are integrally formed, and the second extension 21 and the pulley track 31 on the fixed part 20 are integrally formed, which facilitates integral demolding, effectively improves production efficiency, and reduces assembly steps.

[0031] In this embodiment, the width of the first extension 11 and the second extension 21 is less than the width of the pulley track 31. Alternatively, the width of the first extension 11 and the second extension 21 joined together is equal to the width of the pulley track 31. This allows the pulley to pass smoothly and steadily.

[0032] In this embodiment, a locking block 12 is provided on one side of the pulley mounting cavity 30 on the movable part 10, and a locking member 22 that cooperates with the locking block 12 is provided on one side of the pulley mounting cavity 30 on the fixed part 20. The locking block 12 and the locking member 22 have various cooperative structural forms in the prior art, which will not be described in detail here.

[0033] In this embodiment, the outer end face of the moving part 10 is provided with a first closing baffle 13, and the outer end face of the fixed part 20 is provided with a second closing baffle 23. When the moving part 10 and the fixed part 20 are engaged, the first closing baffle 13 and the second closing baffle 23 are arranged opposite to each other.

[0034] In practical implementation, when the moving part 10 and the fixed part 20 are connected, the seams on both sides of the closure can be covered by the first closing baffle 13 and the second closing baffle 23, which can improve the visual appearance.

[0035] In this embodiment, the moving part 10 and the fixed part 20 are provided with screw connection holes 32 for connecting with the profile. The screw connection holes 32 are used to connect the fixed track profile and the moving track profile.

[0036] Where there is no conflict, the above embodiments and features can be combined with each other.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
