Description

Technical Field

[0001] The utility model belongs to the field of locking mechanisms, and in particular relates to a lightweight slide rail for machines. Background Art

[0002] Aircraft interiors contain a wide variety of electronic components. To prevent unwanted objects from entering, some are stored together in large cabinets, while others are individually housed in smaller cabinets. Regardless of the placement method, the electronic components must be contained within a sealed space and protected. Maintenance of electronic components in confined spaces can be difficult, so a combination of mounting plates and slide rails is typically used to remove them from the space for easy maintenance and installation.

[0003] A slide rail is a sliding guide composed of a track and bearings that restricts the trajectory of movement, allowing mechanical components to follow a specific path. Slide rails must possess a certain load capacity, low friction and stability during movement, and maintain stable guidance accuracy over time, even under high-speed movement and emergency stops. A baseplate is installed between a pair of slide rails, supporting and securing the object being moved.

[0004] The current slide rails are not suitable for the aerospace or aircraft fields, and the existing slide rails are prone to sliding and cannot be limited. Since they are easy to slide, it is impossible to repair electronic components directly on the bottom plate, and it is easy to cause electronic components to fall or be damaged. Summary of the Invention

[0005] The purpose of the utility model is to provide a lightweight slide rail for machines to solve the problems that the existing slide rails are prone to sliding and cannot be limited. Due to the easy sliding, electronic components cannot be directly repaired on the bottom plate, and the electronic components are easily caused to fall or be damaged.

[0006] The utility model adopts the following technical solution: a lightweight slide rail for a machine, comprising:

[0007] an outer track, the side of which is mounted on the machine body;

[0008] The middle track is set inside the outer track and can slide along the direction of the outer track;

[0009] The inner track is sleeved inside the middle track and can slide along the middle track; its inner side is used to install the support plate; one end of the inner track is the inner end, and the other end is the outer end;

[0010] The fixed bracket is fixedly connected to the inner end of the inner track and is used to clamp the inner track when the middle track extends out of the outer track and the inner track is fully extended from the middle track, forcing the inner track to remain in a fully extended state, thereby allowing the support plate installed on the inner track to extend outward and present the items carried on the support plate.

[0011] Furthermore, the cross section of the outer rail is "U"-shaped, and is composed of a first side plate and two first ear plates connected in one piece, and the inner walls of the two first ear plates are provided with first grooves;

[0012] The cross-section of the middle rail is "U"-shaped, and is composed of a second side plate and two second ear plates connected as one body. The outer walls of the two second ear plates are provided with a second groove; the second groove and the first groove cooperate with each other to form a first accommodating area for accommodating multiple first steel balls, and each first steel ball is used to reduce the friction between the outer rail and the middle rail.

[0013] Furthermore, a third groove is provided on the inner walls of the two second ear plates, and a fourth groove is provided at a position on the inner rail corresponding to the third groove. The third groove and the fourth groove cooperate with each other to form a second accommodating area for accommodating multiple second steel balls, and each second steel ball is used to reduce the friction between the inner rail and the middle rail.

[0014] Furthermore, a first stopper is fixedly connected to an opening at one end of the outer track, and the first stopper is used to prevent the middle track from sliding out of the inner cavity of the outer track. A second stopper is fixedly connected to an opening at one end of the middle track, and the second stopper is used to prevent the inner track from sliding out of the inner cavity of the middle track.

[0015] Furthermore, both ends of the first accommodating area and the second accommodating area are provided with fixing pins for preventing the first steel ball and the second steel ball from overflowing from the first accommodating area and the second accommodating area.

[0016] Furthermore, the fixing bracket is located in the middle section of the middle track, and the fixing bracket includes:

[0017] a limiting plate, one end of which is fixedly connected to the inner end of the inner track;

[0018] The trigger rod is hinged at its middle part to the other end of the limit plate; the trigger rod is arranged along the direction of the inner track and is used to abut against the other end of the outer track, thereby clamping the middle track and preventing the middle track and the inner track from retracting into the inner cavity of the outer track.

[0019] Furthermore, an elastic member receiving groove is provided on the trigger rod, and the end of the limit plate extends outward and wraps around the trigger rod and then extends inward toward the axis of the track to form a third receiving area for receiving the trigger rod; the two ends of the trigger rod are a free end and a limit end respectively;

[0020] The mounting bracket also includes:

[0021] One end of the first elastic member extends into the elastic member receiving groove, and the other end is fixedly connected to the corresponding limiting plate. The first elastic member is used to force the limiting end of the trigger rod to approach the middle rail and abut against the end of the outer rail after it is separated from the outer rail.

[0022] Furthermore, the free end of the trigger rod is also used to press it along the axis direction of the inner rail, and force the limiting end of the trigger rod to move away from the middle rail and outside the outer rail, thereby moving with the inner rail when the inner rail and the middle rail shrink.

[0023] The beneficial effects of the utility model are:

[0024] The utility model has light weight and good stability. When the inner rail is fully extended, the fixed bracket is activated and the inner rail will not be retracted due to sliding, thereby completing the locking of the inner rail, which is convenient for direct upgrading and maintenance of electronic components. When the fixed bracket needs to be retracted, the free end of the trigger rod is pressed, so that the limit end of the trigger rod is away from the middle rail and located outside the outer rail, and then moves with the inner rail when the inner rail and the middle rail are retracted.

[0036] The utility model discloses a light-weight slide rail for a machine. Figure 1 and 4 As shown, it includes an outer rail 10 , a middle rail 20 , an inner rail 30 , and a fixing bracket 40 .

[0037] The outer rail 10 is installed on the side of the machine body; the middle rail 20 is sleeved inside the outer rail 10 and can slide along the direction of the outer rail 10; the inner rail 30 is sleeved inside the middle rail 20 and can slide along the direction of the middle rail 20; the inner side of the inner rail 30 is used to install the support plate; one end of the inner rail 30 is the inner end, and the other end is the outer end.

[0038] The fixing bracket 40 is fixedly connected to the inner end of the inner rail 30. The fixing bracket 40 is used to clamp the inner rail 30 after the middle rail 20 extends out of the outer rail 10 and the inner rail 30 fully extends out of the middle rail 20, forcing the inner rail 30 to remain in a fully extended state, thereby allowing the support plate installed on the inner rail 30 to extend outward and present the items carried on the support plate.

[0039] The cross section of the outer rail 10 is U-shaped. The outer rail 10 is composed of a first side plate 11 and two first ear plates 12 connected as one body. The inner walls of the two first ear plates 12 are provided with first grooves 13 .

[0040] The cross-section of the middle rail 20 is "U"-shaped. The middle rail 20 is composed of a second side plate 21 and two second ear plates 22 connected as one body. The outer walls of the two second ear plates 22 are provided with a second groove 23; the second groove 23 and the first groove 13 cooperate with each other to form a first accommodating area for accommodating multiple first steel balls, each of which is used to reduce the friction between the outer rail 10 and the middle rail 20.

[0041] A third groove is provided on the inner walls of the two second ear plates 22, and a fourth groove 31 is provided on the inner rail 30 at a position corresponding to the third groove. The third groove and the fourth groove 31 cooperate with each other to form a second accommodating area for accommodating multiple second steel balls, each of which is used to reduce the friction between the inner rail 30 and the middle rail 20.

[0042] A first stopper 14 is fixedly connected to an opening at one end of the outer rail 10, and the first stopper 14 is used to prevent the middle rail 20 from sliding out of the inner cavity of the outer rail 10. A second stopper 25 is fixedly connected to an opening at one end of the middle rail 20, and the second stopper 25 is used to prevent the inner rail 30 from sliding out of the inner cavity of the middle rail 20.

[0043] Both ends of the first accommodating area and the second accommodating area are provided with fixing pins for preventing the first steel ball and the second steel ball from overflowing from the first accommodating area and the second accommodating area.

[0044] The fixing bracket 40 is located in the middle section of the middle track 20. Figure 2 As shown, the fixing bracket 40 includes a limiting plate 41 and a trigger rod 42 .

[0045] One end of the limit plate 41 is fixedly connected to the inner end of the inner rail 30; the middle part of the trigger rod 42 is hinged to the other end of the limit plate 41; the trigger rod 42 is arranged along the direction of the inner rail 30, and the trigger rod 42 is used to abut against the other end of the outer rail 10, thereby clamping the middle rail 20 and preventing the middle rail 20 and the inner rail 30 from retracting into the inner cavity of the outer rail 10.

[0046] like Figure 3 As shown, an elastic member accommodating groove is provided on the trigger rod 42, and the end of the limit plate 41 extends outward and wraps around the trigger rod 42 and then extends toward the axis of the inner track 30 to form a third accommodating area, which is used to accommodate the trigger rod 42; the two ends of the trigger rod 42 are respectively a free end and a limit end 43.

[0047] The fixing bracket 40 also includes: a first elastic member, one end of the first elastic member extends into the elastic member receiving groove, and the other end of the first elastic member is fixedly connected to the corresponding limiting plate 41. The first elastic member is used to force the limiting end 43 of the trigger rod 42 to approach the middle rail 20 and abut against the end of the outer rail 10 after it is separated from the outer rail 10.

[0048] The free end of the trigger rod 42 is also used to press the inner rail 30 along the axial direction of the inner rail 30, and force the limiting end 43 of the trigger rod 42 to move away from the middle rail 20 and be located outside the outer rail 10, thereby moving with the inner rail 30 when the inner rail 30 and the middle rail 20 are contracted.

[0049] During use, the present invention installs a support plate between the two inner rails 30 and places electronic components on the support plate. The rails of the present invention are installed in multiple cavities arranged from top to bottom on a mounting frame. Therefore, each pair of slide rails needs to be installed with a support plate, and different electronic components are placed on them respectively.

[0050] The slide rail of the present invention is provided with two mirror-image outer rails 10, middle rails 20, and inner rails 30. The two outer rails 10, middle rails 20, and inner rails 30 are arranged opposite each other and installed in the same accommodating cavity. The installation position of the first elastic member in the present invention should be biased towards the limiting end of the trigger lever 42. This allows the limiting end to more easily approach the middle rail 20 and abut the end of the outer rail 10. It also facilitates the limiting end of the trigger lever 42 to abut against the outer rail 10 after the free end of the trigger lever 42 loses force.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
