Description

Technical Field

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

[0002] There are all kinds of electronic components inside the aircraft. In order to prevent the entry of unnecessary objects, some need to be placed in large cabinets, while others need to be placed separately in small cabinets. Regardless of the placement method, the electronic components should be placed in a closed space and protected. In a closed space, it will be difficult to maintain electronic components. Generally, a combination of a mounting base and a slide rail is used to pull the electronic components out of the space for maintenance and installation.

[0003] A slide rail is a sliding guide composed of a track and a bearing that can limit the trajectory of movement and move mechanical parts along a specific path. The slide rail needs to have a certain load-bearing capacity, small and stable friction when moving, and can maintain the guiding accuracy for a long time even under high-speed movement and emergency stop conditions. A base plate is installed between a pair of slide rails so that the base plate can carry and fix the object to be moved.

[0004] The current slide rails are not applicable to the aerospace or aircraft fields, and the existing slide rails are prone to sliding and cannot be limited. Since they are easy to slide, electronic components cannot be repaired directly on the bottom plate, and the electronic components are prone to falling or being damaged. Summary of the invention

[0005] The purpose of the present invention is to provide a lightweight slide rail for machines to solve the problem that the existing slide rail is easy to slide 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 present invention 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 in the middle track and can slide along the middle track; the inner side of the inner track 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 fully extends out of 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, and 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 gear lever is fixedly connected to an opening at one end of the outer track, and the first gear lever is used to prevent the middle track from sliding out of the inner cavity of the outer track. A second gear block is fixedly connected to an opening at one end of the middle track, and the second gear block 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 the first accommodating area and the second accommodating area.

[0016] Further, 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 has its middle part hinged with 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 the trigger rod and then extends toward the axis of the inner track to form a third receiving area, and the third receiving area is used to receive the trigger rod; the two ends of the trigger rod are a free end and a limit end respectively;

[0020] The fixing bracket also includes:

[0021] The first elastic member has one end extending into the elastic member receiving groove and the other end 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 track and abut against the end of the outer track after leaving the outer track.

[0022] Furthermore, the free end of the trigger rod is also used to press the inner rail along the axial direction thereof, and force the limiting end of the trigger rod to be away from the middle rail and located outside the outer rail, thereby moving with the inner rail when the inner rail and the middle rail are contracted.

[0023] The beneficial effects of the present invention are:

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

[0036] The present invention discloses a portable slide rail for a machine, such as 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 body at the side; the middle rail 20 is sleeved in the outer rail 10 and can slide along the outer rail 10; the inner rail 30 is sleeved in the middle rail 20 and can slide along 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 fixed bracket 40 is fixedly connected to the inner end of the inner rail 30. The fixed 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 in one piece. 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 second grooves 23; the second grooves 23 and the first grooves 13 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 10 and the middle rail 20.

[0041] A third groove is formed on the inner walls of the two second ear plates 22, and a fourth groove 31 is formed 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, and each second steel ball is used to reduce the friction between the inner rail 30 and the middle rail 20.

[0042] A first gear lever 14 is fixedly connected to an opening at one end of the outer track 10, and the first gear lever 14 is used to prevent the middle track 20 from sliding out of the inner cavity of the outer track 10. A second gear block 25 is fixedly connected to an opening at one end of the middle track 20, and the second gear block 25 is used to prevent the inner track 30 from sliding out of the inner cavity of the middle track 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 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 limiting 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 a free end and a limiting end 43 respectively.

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

[0048] The free end of the trigger rod 42 is also used to press the inner rail 30 along the axial direction thereof and force the limiting end 43 of the trigger rod 42 to be away from the middle rail 20 and 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 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 respectively.

[0050] The outer rail 10, the middle rail 20, and the inner rail 30 of the slide rail of the present invention are mirror-imaged, and the two outer rails 10, the middle rail 20, and the inner rail 30 are arranged opposite to each other and installed in the same accommodating cavity. The installation position of the first elastic member in the present invention should be biased toward the limit end of the trigger rod 42, so that the limit end can be closer to the middle rail 20 and abut against the end of the outer rail 10, and it is also more conducive to the limit end of the trigger rod 42 being attached to the outer rail 10 after the free end of the trigger rod 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 substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
