Description

Technical Field

[0001] The utility model relates to a load-bearing slide rail, in particular to a load-bearing slide rail mechanism component. Background Art

[0002] In the prior art, when installing the drawer type slide rail, a pair of slide rails is installed on the left and right sides respectively, which are used to pull out objects, and are pulled out when in use and pushed in after use.

[0003] The existing design of drawer-type slide rails is to install one pair on each side of the drawer, and install them longitudinally. They can only bear longitudinal force, and the load-bearing capacity is small. The rails are easily damaged. They are only suitable for bearing longitudinal loads, and the overall cost is relatively high. If only two pairs of existing drawer-type slide rails are installed horizontally at the bottom of the drawer-type object, because the existing drawer-type slide rail structure has no effective surrounding support on the outer track side, the internal ball bearing fixing structure is relatively thin, and the limit device is too far back, resulting in no effective surrounding support around the upper slide rail, and the internal ball bearing fixing is relatively thin. When pulled out to the maximum length, even if only a small amount of objects are placed in the drawer, the drawn drawer itself will bend and fall downward.

[0004] After testing, two sets of drawer-type slide assemblies available on the market were installed at the bottom of the object. After the lower slide was fixed, the upper slide was pulled out, and a battery pack weighing 35KG was placed on top of the upper slide. The upper slide directly slipped off the lower fixed slide track, and the upper slide was bent, deformed and damaged. The battery pack and the upper slide fell to the ground, causing injuries to people and damage to the battery pack. Summary of the invention

[0005] In view of the above existing technical problems, the utility model provides a load-bearing slide rail mechanism component. The slide rail component is a high-strength transverse slide rail that can bear a large weight and only requires one pair of slide rails, thereby reducing the space occupied by the slide rails and reducing costs.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions: a load-bearing slide rail mechanism component, including an upper slide rail and a lower slide rail; the left and right sides of the lower slide rail are bent to form a slide groove, and the top is a semi-enclosed structure, the front and rear ends of the lower slide rail are open for the upper slide rail to pass through, a lower limit device is provided at the front end of the lower slide rail, and a plurality of screws for fixing are provided on the lower slide rail; the upper slide rail is a U-shaped slide plate, a plurality of lower rollers are provided on both sides, an upper limit device is provided at the middle and rear end of the upper slide rail, the upper slide rail is slidably arranged in the lower slide rail, and the lower roller slides in the slide groove, and the upper slide rail is limited from escaping from the lower slide rail by the upper limit device and the lower limit device, and a plurality of screws for fixing are provided on the upper slide rail.

[0007] Furthermore, the utility model provides that the upper limit device is a limit plate, the lower limit device is a stop block, the upper slide rail has a through hole, the bottom of the limit plate extends into the through hole, and when the upper slide rail is pulled out, the stop block blocks the limit plate and restricts the upper slide rail from continuing to slide outward.

[0008] The utility model further provides upper rollers on the upper left and right sides of the rear portion of the upper slide rail, and the tops of the upper rollers protrude upward from the upper slide rail.

[0009] The utility model further has a top portion of the upper roller protruding from the upper slide rail by 1.7 mm, and a bottom portion of the lower roller protruding from the upper slide rail by 1.5 mm.

[0010] Furthermore, in the utility model, anti-wear rings are arranged on the left and right sides of the end of the upper slide rail.

[0011] Furthermore, the top of the slideway groove is bent upward by 90 degrees.

[0012] Furthermore, the screw of the utility model is a cross groove spring flat washer combination screw.

[0013] The beneficial effects of adopting the above technical scheme are as follows: the utility model is used for bottom installation and fixing, and is a high-strength transverse slide rail. The upper slide rail is bent multiple times to form a semi-enclosed slide groove, and the structure is firm and reliable. The upper slide rail is used to install the drawer tray, and the drawer tray moves with the upper slide rail. The bottom screw of the lower slide rail is fixed in the chassis or on the furniture firmly and reliably. The multiple screws above the upper slide rail are used to fix the drawer tray for placing heavy objects. The tray can be adjusted according to the size of the object. The slide rail assembly only needs one pair of slide rails, which reduces the space occupied by the slide rails, has low cost, and can bear a large weight. And after a part of the upper slide rail of the utility model is pulled out, there is a limit device to prevent it from being pulled out too much. The upper slide rail will not bend and deform due to insufficient support points. This mechanism can withstand heavy objects. A row of precision small rollers are installed on the lower sides of the upper slide rail. When the upper slide rail is pulled out, it can slide effectively and smoothly, and the front and back push and pull are smooth. The upper slide rail will not be deformed and fall out due to the lack of effective support after the object is too heavy, thereby preventing heavy objects from falling and being damaged on the slide rail, protecting the safety of personnel and equipment.

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] An embodiment of the present utility model: Figure 1 and Figure 2 As shown, a load-bearing slide rail mechanism assembly includes an upper slide rail 2 and a lower slide rail 3; the left and right sides of the lower slide rail 3 are bent to form a slide groove 7, and the top is a semi-enclosed structure. The front and rear ends of the lower slide rail 3 are open for the upper slide rail 2 to pass through, and a lower limit device 1 is provided at the front end of the lower slide rail 3, and a plurality of screws 5 for fixing are provided on the lower slide rail 3; the upper slide rail 2 is a U-shaped slide plate, and a plurality of lower rollers 6 are provided on both sides, and an upper limit device 4 is provided at the middle and rear ends of the upper slide rail 2. The upper slide rail 2 is slidably set in the lower slide rail 3, and the lower rollers 6 slide in the slide groove 7. The upper slide rail 2 is restricted from escaping from the lower slide rail 3 by the upper limit device 4 and the lower limit device 1, and a plurality of screws 5 for fixing are provided on the upper slide rail 2. The utility model is used for bottom installation and fixation, and is a high-strength transverse slide rail. The lower slide rail 3 is bent multiple times to form a semi-enclosed slide groove, and the structure is sturdy and reliable. The upper slide rail 2 is used to install a drawer tray, and the drawer tray moves with the upper slide rail. Figure 5As shown, the screws 5 at the bottom of the lower slide rail 3 are fixed firmly and reliably in the chassis or on the furniture, and the multiple screws 5 above the upper slide rail 2 are used to fix the drawer tray for placing heavy objects. The tray can be adjusted according to the size of the object. Usually, the slide rail assembly only needs one pair of slide rails, which reduces the space occupied by the slide rails, reduces the cost, and can bear a large weight.
