Description

Technical Field

[0001] This utility model belongs to the field of home furnishing manufacturing, and specifically relates to a drawer slide device with a fully synchronized function. Background Technology

[0002] Three-section drawer slides are a common type of furniture hardware, widely used in furniture with drawers. Three-section slides have a longer draw distance than two-section slides, allowing the drawer to be fully extended, thus making them more practical. Three-section slides mainly consist of a fixed rail, a middle rail, and a top rail. Rolling elements are installed between the fixed rail and the middle rail, and between the middle rail and the top rail, to ensure smooth sliding. These rolling elements are mounted on cages. Typically, the middle rail also has a gear that engages with the racks on the cages of the two sets of rolling elements to ensure the synchronization of the middle and top rail's drawer movement.

[0003] However, the load-bearing capacity of the existing three-section drawer slides needs to be improved, and when the drawer moves too fast, it is prone to wobbling in the left-right or up-down directions, which makes the drawer slide in and out unevenly and unsmoothly. Therefore, the stability of the existing three-section drawer slides also needs to be further improved. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a drawer slide device with a fully synchronized function. The drawer slide device has a stable and smooth pull-out and closing effect, which can greatly extend the service life of the slide.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is:

[0006] A drawer slide device with fully synchronized function includes slides disposed on both sides of the drawer and a synchronized drive mechanism disposed between the slides on both sides. Each slide includes a bracket, a lower rail disposed on the bracket, a middle rail disposed on the lower rail, and an upper rail disposed on the middle rail. The synchronized drive mechanism includes synchronized drive components disposed on both sides of the drawer and a connecting shaft for connecting the synchronized drive components on both sides. Each synchronized drive component includes a fixed frame and a connecting arm disposed on the fixed frame. One end of the connecting arm is connected to the upper rail, and the other end is connected to the fixed frame via a gear and rack mechanism. The gear and rack mechanism includes a rack disposed on the fixed frame and a gear disposed on the connecting arm. The gear is rotatably connected to the connecting arm and meshes with the rack. The gear between the synchronized drive components on both sides is connected via the connecting shaft.

[0007] Preferably, a sliding guide mechanism is provided between the connecting arm and the fixed frame. The sliding guide mechanism includes a slide rail disposed on the fixed frame and a slider disposed on the fixed frame. The slide rail is disposed on the inner side of the fixed frame, and the slider is mounted on the connecting arm and cooperates with the slide rail.

[0008] Preferably, the connecting arm is provided with a limiting slot, which engages with the outer side of the fixing frame.

[0009] Preferably, the upper surface of the upper rail is provided with a first mounting slot, and the connecting arm is provided with a first locking tongue that cooperates with the first mounting slot.

[0010] Preferably, the outer side of the upper rail is provided with a second mounting slot, and the connecting arm is provided with a second locking tongue that cooperates with the second mounting slot.

[0011] Preferably, the outer side of the lower rail is provided with several sets of third locking tongues, and the fixing frame is provided with a third latch that cooperates with the third locking tongues.

[0012] Preferably, both the bracket and the fixing frame are L-shaped.

[0016] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0017] In this invention's fully synchronized drawer slide device, the upper rail moves, driving the connecting arm, which in turn drives the gear to crawl on the rack. The rotation of the gear simultaneously drives the connecting shaft, causing the gears on both sides to rotate synchronously. This synchronization ensures that the connecting arms and upper rails on both sides move synchronously, allowing the drawer to be pulled out horizontally. This design ensures a stable and smooth drawer slide device with full synchronization, significantly extending the lifespan of the slide. Attached Figure Description

[0059] See Figures 1-16 The lower rail 13 includes a first lower rail piece arranged horizontally and second lower rail pieces arranged on both sides of the first lower rail piece. The second lower rail piece on the left extends vertically upward and bends inward in an arc shape to form a third lower rail piece; the second lower rail piece on the right extends vertically upward and bends inward horizontally to form a fourth lower rail piece that extends horizontally.

[0060] See Figures 1-16 The center rail 12 includes a first center rail connector arranged horizontally and second center rail connectors arranged on both sides of the first center rail connector; the second center rail connectors on both sides extend vertically upward and bend horizontally outward to form a third center rail connector extending horizontally; wherein, a fourth center rail connector is arranged between the second center rail connector on the left and the first center rail connector, the fourth center rail connector being an arc segment, the upper end of which is connected to the bottom of the second center rail connector on the left, and the lower end of which is connected to the first center rail connector; a fifth center rail connector is arranged between the second center rail connector on the right and the first center rail connector, the fifth center rail connector being attached to the first center rail connector, and one end of which is connected to the bottom of the second center rail connector, and the other end of which is arc-connected to the first center rail connector.

[0062] See Figures 1-16 The first upper load-bearing component includes a first upper load-bearing frame and a first upper load-bearing wheel assembly 14 disposed on the first upper load-bearing frame. The first upper load-bearing frame is mounted on the middle rail 12. The first upper load-bearing wheel assembly 14 is rotatably connected to the first upper load-bearing frame, and the top of the first upper load-bearing wheel assembly 14 contacts the upper rail 5.

[0063] See Figures 1-16 The second upper load-bearing component includes a second upper load-bearing wheel set 15 disposed on the middle rail 12. The second upper load-bearing wheel set 15 is rotatably connected to the middle rail 12, and the upper end of the second upper load-bearing wheel set 15 is in contact with the upper rail 5.

[0064] See Figures 1-16The third upper load-bearing component 21 includes a third upper load-bearing frame 211, a third upper load-bearing wheel assembly 212 disposed in the middle of the third upper load-bearing frame 211, and a fourth upper load-bearing wheel assembly 213 disposed on the left and right sides of the third upper load-bearing frame 211. The third upper load-bearing wheel assembly 212 is located in the second mounting groove B; the fourth upper load-bearing wheel assembly 213 on the left is installed in the first mounting groove A, and the fourth upper load-bearing wheel assembly 213 on the right is installed in the third mounting groove C.

[0065] See Figures 1-16 The first lower load-bearing component includes a first lower load-bearing frame and a first lower load-bearing wheel assembly 16 disposed on the first lower load-bearing frame. The first lower load-bearing wheel assembly 16 is rotatably connected to the first lower load-bearing frame, and the bottom of the first lower load-bearing wheel assembly 16 contacts the lower rail 13. The middle rail 12 is provided with a clearance groove for avoiding the first lower load-bearing wheel assembly 16.

[0066] See Figures 1-16 The second lower load-bearing component 20 includes a second lower load-bearing frame 201, a second lower load-bearing wheel assembly 202 disposed in the middle of the second lower load-bearing frame 201, and a third lower load-bearing wheel assembly 203 and a fourth lower load-bearing wheel assembly 204 respectively disposed on the left and right sides of the second lower load-bearing frame 201. The second lower load-bearing wheel assembly 202 is located in the fifth mounting groove E; the third lower load-bearing wheel assembly 203 is located in the fourth mounting groove D; and the fourth lower load-bearing wheel assembly 204 is located in the sixth mounting groove F.

[0067] See Figures 1-16 The third upper support frame 211 is provided with an upper guide wheel assembly 214, which is located in the first mounting groove A and the third mounting groove C respectively; the second lower support frame 201 is provided with a lower guide wheel assembly 205, which is located in the fourth mounting groove D.

[0068] In this embodiment, the first upper load-bearing roller group 14, the second upper load-bearing roller group 15, the third upper load-bearing roller group 212, the fourth upper load-bearing roller group 213, the first lower load-bearing roller group 16, the second lower load-bearing roller group 202, and the third lower load-bearing roller group 203 are all load-bearing rollers; all load-bearing rollers are vertically arranged; the fourth lower load-bearing roller group 204 is a ball bearing; the upper guide roller group 214 and the lower guide roller group 205 are both guide rollers, and all guide rollers are horizontally arranged.

[0069] By setting the first upper load-bearing roller group 14, the second upper load-bearing roller group 15, the third upper load-bearing roller group 212, the fourth upper load-bearing roller group 213, the first lower load-bearing roller group 16, the second lower load-bearing roller group 202, the third lower load-bearing roller group 203, and the fourth lower load-bearing roller group 204, the upper rail 5 and the middle rail 12 can be supported and limited vertically, so that the drawer slide rail device with complete synchronization function of this utility model has sufficient load-bearing capacity; at the same time, since the upper guide roller group 214 and the lower guide roller group 205 are set, the upper rail 5 and the middle rail 12 can be limited horizontally, thereby ensuring that the drawer slide rail device with complete synchronization function of this utility model has better stability during operation.

[0070] See Figures 1-16 A gear and rack transmission mechanism is provided between the middle rail 12 and the upper rail 5, and between the middle rail 12 and the lower rail 13. The gear and rack transmission mechanism includes a transmission gear 17 on the middle rail 12, a first transmission rack 18 on the upper rail 5, and a second transmission rack 19 on the lower rail 13. The first transmission rack 18 meshes with the upper end of the transmission gear 17, and the second transmission rack 19 meshes with the lower end of the transmission gear 17.

[0071] The drawer slide device with fully synchronized function of this utility model has a gear and rack transmission mechanism between the upper rail 5 and the middle rail 12 and between the middle rail 12 and the lower rail 13. Therefore, through the constraint relationship of the gear and rack transmission mechanism, the movement of the upper rail 5 and the middle rail 12 can be mutually constrained, thereby avoiding problems such as overlapping sliding, collision, or misalignment of the middle rail 12, thus ensuring the stability and reliability of the drawer slide device with fully synchronized function of this utility model.

[0072] In addition, limiting members are provided at both ends of the upper rail 5, the middle rail 12 and the lower rail 13. The limiting members can be used to limit the maximum extension stroke of the drawer slide device with full synchronization function of this utility model, and at the same time, they can prevent the upper load-bearing wheel mechanism and the lower load-bearing mechanism from dislodging from the upper rail 5, the middle rail 12 and the lower rail 13.

[0073] (2) Height adjustment device IV

[0074] See Figures 17-27 The height adjustment device IV includes an adjustment member mounted on the upper rail 5, an adjustment mechanism for adjusting the height of the adjustment member, and a locking mechanism for fixing the height of the adjustment member.

[0075] The adjusting component includes a horizontal support plate 4, and a first guide support portion 8 is provided at the bottom of the horizontal support plate 4; the first guide support portion 8 is inclined; in this embodiment, there are three sets of the first guide support portions 8, and the three sets of the first guide support portions 8 are arranged side by side; the surface of the upper rail 5 is provided with a clearance groove 502 for avoiding the horizontal support plate 4 and the adjusting mechanism, and the upper rail 5 is provided with a first guide support plate 501 that extends downward inclined toward the clearance groove 502, and the inclination angle of the first guide support plate 501 is the same as the inclination angle of the first guide support portion 8;

[0076] The adjustment mechanism includes a second guide support plate 3 disposed on one side of the horizontal support plate 4 and a push plate 2 for driving the second guide support plate 3 to move. The second guide support plate 3 is connected to the side of the upper rail 5 via a sliding guide mechanism. The sliding guide mechanism is used to cause the horizontal support plate 4 to move in the opposite direction to the first guide support plate 501 along the extension direction of the first guide support plate 501, so as to cause the horizontal support plate 4 to tilt and lift in a horizontal state. The push plate 2 is mounted on the second guide support plate 3.

[0077] See Figures 17-27 The sliding guide mechanism includes a guide shaft disposed on the side of the upper rail 5 and a guide groove 301 disposed on the second guide support plate 3. The guide groove 301 extends obliquely upward, and its extension angle is the same as the oblique angle of the second guide support plate 3. One end of the guide shaft is mounted on the side of the upper rail 5, and the other end passes through the guide groove 301 and is connected to the limiting block 6. The outer diameter of the limiting block 6 is larger than the width of the guide groove 301, thereby preventing the guide shaft from coming out of the guide groove 301.

[0078] See Figures 17-27The locking mechanism includes a locking groove 503 disposed on the upper rail 5 and a locking block 9 disposed on the push plate 2 that cooperates with the locking groove 503. The locking groove 503 is in multiple sets, disposed on the side of the upper rail 5 and arranged sequentially along the extension direction of the guide groove 301. The locking block 9 cooperates with one set of locking grooves 503. In this embodiment, along the arrangement direction of the locking grooves 503, the inclination angle of the front side of the locking groove 503 is smaller than the inclination angle of the rear side of the locking groove 503. Thus, when the push plate 2 is pushed to cause the second guide support plate 3 to tilt upwards, the locking block 9 on the push plate 2 contacts the front side of the locking groove 503, allowing the locking block 9 to climb along the front side of the locking groove 503 and enter the corresponding locking groove 503 (i.e., the front side). The locking block 9 is blocked by the rear side of the locking groove 503, preventing it from entering the locking groove 503 in the opposite direction. This effectively confines the locking block within the corresponding locking groove 503. The push plate 2 and the second guide support plate 3 are flexibly connected. When the drawer height needs to be adjusted downwards, the installer pushes the push plate 2 upwards, causing the locking block 9 on the push plate 2 to separate from the locking groove 503 on the upper rail 5. Then, the installer pushes the push plate 2 in the opposite direction, thereby causing the second guide support plate 3 to tilt downwards, which in turn causes the horizontal support plate 4 to tilt downwards in a horizontal state. When the horizontal support plate 4 falls to the appropriate height, the push plate 2 is released, and the locking block 9 in the push plate 2 is once again locked in the corresponding locking groove 503, stabilizing the horizontal support plate 4 at a fixed height.

[0079] See Figures 17-27 A first limiting block 7 is provided on the inner side of the upper rail 5. The first limiting block 7 is installed on the push plate 2, and the gap between the first limiting block 7 and the push plate 2 forms a limiting groove. The side wall of the upper rail 5 is located in the limiting groove. The width of the limiting groove is greater than or equal to the wall thickness of the side wall of the upper rail 5. Since the push plate 2 and the second guide support plate 3 are flexibly connected, the push plate 2 is prone to horizontal torsion when the installer pushes the push plate 2 to drive the second guide support plate 3 to tilt. Therefore, by setting the first limiting block 7, the limiting groove formed between the first limiting block 7 and the push plate 2 can clamp the side wall of the upper rail 5, thereby limiting the horizontal torsion of the push plate 2. In this way, the force applied by the installer to the push plate 2 can only push the push plate 2 to tilt, thereby better driving the second guide support plate 3 to move, and thus realizing the adjustment of the height of the horizontal support plate 4, and improving the user experience.

[0080] See Figures 17-27The horizontal support plate 4 has a second limiting block 10 at its end away from the first guide support plate 501. The second limiting block 10 includes a first limiting part 1001 and a second limiting part 1002 disposed at the bottom of the first limiting part 1001. The first limiting part 1001 is vertically disposed, and the second limiting part 1002 is inclined, with the inclination angle being the same as the inclination angle of the first guide support plate 501. The upper and lower sides of the first guide support plate 501 are located between the first guide support part 8 and the second limiting part 1002. By setting the second limiting block 10, the horizontal support plate 4 can be limited so that it can only move along the inclined direction of the first guide support plate 501. In other words, the first guide support part 8 of the horizontal support plate 4 and the first limiting part 1001 and the second limiting part 1002 in the second limiting block 10 together constitute a guide groove; while the first guide support plate 501 constitutes a guide part that cooperates with the guide groove, thereby enabling the two to slide relative to each other. During the sliding process, the horizontal support plate 4 always moves along the inclined direction of the first guide support plate 501, and when the horizontal support plate 4 moves in an inclined direction, the surface of the horizontal support plate 4 always maintains a horizontal posture.

[0081] See Figures 17-27 A damping buffer 1 is provided between the upper rail 5 and the fixed rail; the housing of the damping buffer 1 is provided with a second guide support part 101 at a position corresponding to the second guide support plate 3, and the inclination angle of the second guide support part 101 is the same as the inclination angle of the guide groove 301; by providing the second guide support part 101, the movement of the second guide support plate 3 can be guided and supported, thereby ensuring the adjustment accuracy of the adjustment mechanism for the height adjustment of the horizontal support plate 4.

[0082] See Figures 17-27 The working principle of the degree adjustment device of this utility model is as follows:

[0083] When the height of the drawer needs to be adjusted upwards, the installer can push the push plate 2, which will cause the second guide support plate 3 to tilt upwards, and then cause the horizontal support plate 4 to tilt upwards in a horizontal state. After adjusting to a suitable height, the push plate 2 is released, and the locking block 9 in the push plate 2 is locked in the corresponding locking groove 503, thereby locking the second guide support plate 3 and stabilizing the horizontal support plate 4 at a fixed height.

[0084] When the drawer height needs to be adjusted downwards, the installer pushes the push plate 2 upwards, causing the locking block 9 on the push plate 2 to separate from the locking groove 503 on the upper rail 5. Then, the installer pushes the push plate 2 in the opposite direction, thereby causing the second guide support plate 3 to tilt downwards, which in turn causes the horizontal support plate 4 to tilt downwards in a horizontal posture. When the horizontal support plate 4 falls to the appropriate height, the push plate 2 is released, and the locking block 9 in the push plate 2 is once again locked in the corresponding locking groove 503, so that the horizontal support plate 4 is stabilized at a fixed height again.

[0085] (3) Drawer multi-directional adjustment device II

[0086] See Figures 28-34 The drawer multi-directional adjustment device II includes a base 22, a cover plate 23 disposed on the base 22, an X-axis adjustment mechanism for driving the base 22 and the cover plate 23 to move relative to each other along the X-axis, and a Y-axis adjustment mechanism for driving the base 22 and the cover plate 23 to move relative to each other along the Y-axis.

[0087] The base 22 is mounted on the drawer, and the cover plate 23 is mounted on the movable rail in the slide rail;

[0088] The Y-axis adjustment mechanism includes an adjustment seat 29 disposed between the base 22 and the cover plate 23, and a Y-axis adjustment wheel 27 disposed on the adjustment seat 29. The Y-axis adjustment wheel 27 is rotatably connected to the adjustment seat 29, and a first spiral adjustment block is disposed on the Y-axis adjustment wheel 27. The first spiral adjustment block extends spirally along the circumferential direction of the Y-axis adjustment wheel 27, and the diameter of the first spiral adjustment block gradually increases. The base 22 is provided with multiple sets of first driving blocks 31 at positions corresponding to the first spiral adjustment blocks. The multiple sets of first driving blocks 31 are arranged equidistantly in a straight line along the Y-axis direction. In this embodiment, a Y-axis guide mechanism is disposed between the adjustment seat 29 and the base 22. The Y-axis guide mechanism consists of multiple sets.

[0090] See Figures 28-34 A locking structure is provided between the cover plate 2 and the movable rail. The locking structure includes a first locking block 25, a second locking block 26, and an unlocking member 24 for driving the first locking block 25 to move along the X-axis to separate the first locking block 25 and the second locking block 26. The movable rail is provided with a locking groove 30 that cooperates with the first locking block 25 and the second locking block 26. The first locking block 25 is slidably connected to the cover plate 23 and is connected to the cover plate 23 by a spring. The spring force causes the first locking block 25 to move toward the second locking block 26. The unlocking member 24 is rotatably connected to the cover plate 2 and is provided with a lever. The first locking block 25 is provided with a drive groove at a position corresponding to the lever, and the lever is located in the drive groove.

[0091] The specific operation is as follows: Move the unlocking component 24 to drive the first locking block 25 to move along the X-axis direction, causing the first locking block 25 and the second locking block 26 to separate. Then, fasten the second locking block 26 into the locking groove 30 of the movable rail. Subsequently, release the locking component, causing the first locking block 25 to move towards the second locking block 26 under the spring force, thereby locking the movable rail. When it is necessary to unlock the movable rail, the operation is as follows: Move the unlocking component 24 to drive the first locking block 25 to move along the X-axis direction, causing the first locking block 25 and the second locking block 26 to separate. Then, remove the second locking block 26 from the locking groove 30 of the movable rail.

[0092] See Figures 28-34 The working principle of the drawer multi-directional adjustment device in this utility model is as follows:

[0093] The installer installs the multi-directional drawer adjustment device of this utility model on the drawer and the sliding rail. Specifically, the base 22 is installed on the drawer, and the cover plate 23 is installed on the sliding rail through the locking mechanism. The specific operation is as follows: the unlocking member 24 is moved to drive the first locking block 25 to move along the X-axis direction to separate the first locking block 25 and the second locking block 26. Then, the second locking block 26 is fastened into the locking groove 30 of the sliding rail. Then, the locking member is released, so that the first locking block 25 moves towards the second locking block 26 under the elastic force of the spring, thereby locking the sliding rail.

[0094] When the drawer position needs to be adjusted up and down, rotate the Y-axis adjusting wheel 27. When the Y-axis adjusting wheel 27 rotates, the first spiral adjusting block set on the Y-axis adjusting wheel 27 also rotates. The first spiral adjusting block is inserted between two adjacent sets of first driving blocks 31. At this time, if the cover plate 23 is used as a reference, that is, the movable rail is the fixed end, the rotation of the Y-axis adjusting wheel 27 can drive the base 22 to move along the Y-axis direction, thereby realizing the up and down adjustment of the drawer position.

[0095] When the drawer position needs to be adjusted left or right, rotate the X-axis adjusting wheel 28. When the X-axis adjusting wheel 28 rotates, the second spiral adjusting block set on the X-axis adjusting wheel 28 also rotates. The second spiral adjusting block is inserted between two adjacent sets of second driving blocks 32. At this time, if the cover plate 23 is still used as a reference, the rotation of the X-axis adjusting wheel 28 can drive the adjusting seat 29 and the base 22 connected to the adjusting seat 29 to move, thereby realizing the left or right adjustment of the drawer position.

[0096] (4) Synchronous drive mechanism III

[0097] See Figures 35-40 The synchronous drive mechanism III includes synchronous drive components disposed on both sides of the drawer and a connecting shaft 38 for connecting the synchronous drive components on both sides; wherein, the synchronous drive component includes a fixing frame 34 and a connecting arm 36 disposed on the fixing frame 34; the fixing frame 34 is L-shaped; one end of the connecting arm 36 is connected to the upper rail 5, and the other end is connected to the fixing frame 34 through a gear and rack mechanism; the gear and rack mechanism includes a rack 35 disposed on the fixing frame 34 and a gear 37 disposed on the connecting arm 36; the gear 37 is rotatably connected to the connecting arm 36, and the gear 37 meshes with the rack 35; the gear 37 between the synchronous drive components on both sides is connected through the connecting shaft 38.

[0098] When the upper rail 5 moves, it drives the connecting arm 36 to move, and the connecting arm 36 drives the gear 37 to crawl on the rack 35. As the gear 37 rotates, it drives the connecting shaft 38 to rotate, so that the gears 37 on both sides rotate synchronously. This keeps the gears 37 on both sides synchronized, so that the connecting arms 36 on both sides and the upper rails 5 on both sides also move synchronously, thus allowing the drawer to be pulled out horizontally.

[0099] See Figures 35-40 A sliding guide mechanism is provided between the connecting arm 36 and the fixed frame 34. The sliding guide mechanism includes a slide rail and a slider disposed on the fixed frame 34. The slide rail is disposed on the inner side of the fixed frame 34. The slider is mounted on the connecting arm 36 and cooperates with the slide rail. This arrangement allows the sliding guide mechanism to guide the movement of the connecting arm 36, thereby improving the movement accuracy of the connecting arm 36. Simultaneously, the cooperation between the slider in the connecting arm 36 and the slide rail on the fixed frame 34 prevents the connecting arm 36 from swaying left and right during movement.

[0100] See Figures 35-40 The connecting arm 36 is provided with a limiting slot 45, which engages with the outer side of the fixing frame 34. Through the above arrangement, the limiting slot 45 of the connecting arm 36 can be engaged with the fixing frame 34, thereby preventing the connecting arm 36 from swaying up and down during movement.

[0101] See Figures 35-40 The upper surface of the upper rail 5 is provided with a first mounting slot 39, and the connecting arm 36 is provided with a first locking tongue 40 that cooperates with the first mounting slot 39; the outer side of the upper rail 5 is provided with a second mounting slot 41, and the connecting arm 36 is provided with a second locking tongue 42 that cooperates with the second mounting slot 41; through the above configuration, one end of the connecting arm 36 can be fixedly connected to the upper rail 5, thereby causing the connecting arm 36 and the upper rail 5 to move synchronously.

[0102] See Figures 35-40 The outer side of the lower rail 13 is provided with several sets of third locking tongues 43, and the fixing frame 34 is provided with third bayonets 44 that cooperate with the third locking tongues 43. Through the above arrangement, the fixing frame 34 can be fixedly connected to the bracket 11. In this embodiment, there are at least two sets of third bayonets 44, and the two sets of third bayonets 44 are respectively arranged in the fixing frame 34 located on the front and rear sides of the lower rail 13, and the opening directions of the two sets of third bayonets 44 are opposite, so as to limit and fix the lower rail 13.

[0103] The above are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
