[0001] The utility model relates to the technical field of slide rails, in particular to an anti-sinking slide rail structure. Background Art

[0002] Slide rails, also known as guide rails and slideways, refer to hardware connection parts fixed to the cabinet of furniture for the movement of drawers or cabinet panels of furniture. Slide rails are suitable for connecting drawers of wooden and steel drawers such as cabinets, furniture, document cabinets, bathroom cabinets, etc. Guide rails are grooves or ridges made of metal or other materials, which can bear, fix, guide moving devices or equipment and reduce their friction.

[0003] The existing public patent (publication number is CN 213992979 U) discloses an anti-sinking slide rail structure, comprising a drawer body for storing items, an inner slide rail and an outer slide rail that help the relevant drawer device to be slidably connected to the cabinet, the inner slide rail being arranged on both sides of the drawer body, and the outer slide rail being fixedly connected to the cabinet. With this anti-sinking slide rail structure, when the drawer is pulled out of the cabinet body or pushed in and closed with the cabinet body, part of the inner slide rail is in a completely suspended state, the load in the drawer is too heavy, or the user applies uneven force, resulting in the inner slide rail sinking, and scratches are likely to occur between the upper drawer and the lower drawer, or between the drawer and the cabinet body, affecting the effect of free and smooth pushing and pulling. At this time, the corresponding hand wheel is rotated as needed, the screw is screwed in along the threaded hole, the push plate is moved to push the steel ball group and the inner slide rail to rise, avoiding the phenomenon of scratches and collisions between the upper drawer and the lower drawer, or between the drawer and the cabinet body caused by the sinking of the inner slide rail, thereby improving the effect of free and smooth pushing and pulling of the drawer.

[0004] Although the above slide rail structure can solve the sinking problem, the structure is complex, which makes the installation and removal of the slide rail more complicated. A simple limit structure can achieve the anti-sinking effect of the above slide rail. Therefore, the utility model proposes an anti-sinking slide rail structure to improve the above problem. Utility Model Content

[0005] The utility model aims to provide an anti-sinking slide rail structure to solve the problems in the above background technology that the existing anti-sinking slide rail structure is complex in composition, difficult to implement, and reduces the practicality of the slide rail itself.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-sinking slide rail structure, comprising a drawer for storing things and a guide rail fixed to the edge of the drawer; the guide rail comprises a guide block fixed to the tail of the drawer side, a positioning strip for fixing the guide block, and a mounting block fixed to the outer end of the positioning strip; the two positioning strips are arranged in parallel, and the positioning strips are fitted on the inner wall of the drawer groove, the guide block is embedded in the end of the positioning strip and is provided with a roller, and the bottom of the drawer is symmetrically provided with a balance bar, and a guide rod is inserted in the balance bar, and the inner end of the guide rod is fixed to the inner wall of the drawer groove.

[0007] Preferably, a panel is fixed to the outer end of the drawer, the panel is buckled into the opening of the drawer groove, and the edge of the panel is arranged in a groove shape.

[0008] Preferably, the mounting block is embedded in the inner wall of the drawer slot, the bottom of the balancing bar is in contact with the bottom side of the drawer slot, and the circular channel in the middle of the balancing bar is in transitional fit with the guide rod.

[0009] Preferably, the groove arranged on the side of the positioning strip cooperates with the raised edge of the guide block, and the inner wall of the guide block fits with the outer wall of the positioning strip.

[0010] Preferably, the roller is fixed to the raised end of the guide block, and the circumference of the roller is movably fitted to the groove surface of the positioning strip.

[0011] Preferably, the positioning bar is a hollow structure, and the positioning bar and the guide rod are arranged in parallel.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model provides a guide rail structure, so that the drawer can slide normally and avoid sinking in the slid-out state, which is convenient for the use of the drawer. The overall structure of the slide rail is simple, and the double limit of the guide rail and the guide rod is used to achieve the movement balance of the drawer, avoid sinking, and facilitate loading and unloading. Compared with the existing slide rail structure, it can not only achieve the purpose of preventing sinking, but also improve its own practicality with a simplified structure.

[0014] During actual use, when the drawer in the initial state is pulled outward along the drawer groove, the guide block fixed relative to the drawer slides relative to the positioning bar. During the sliding process, the rollers installed on the protrusions of the guide block rotate synchronously, and the balance bar fixed at the bottom of the drawer also moves relative to the guide rod. As the drawer is continuously pulled out, the gravity generated by the part of the drawer that is separated from the drawer groove will cause the guide block to tend to sink, but due to the snap fit between the protruding part of the guide block and the groove of the positioning bar, and the auxiliary support of the guide rod to the balance bar, the guide block cannot produce an actual sinking displacement, and can thus move along a straight line, making it convenient for the drawer to move in and out directly.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example

[0021] See also Figure 1-3 , as shown in the figure: This embodiment is a preferred implementation of the technical solution, an anti-sinking slide rail structure, including a drawer 1 for storing things and a guide rail fixed to the edge of the drawer 1; the guide rail includes a guide block 4 fixed to the tail of the side of the drawer 1, a positioning strip 3 for fixing the guide block 4, and a mounting block 5 fixed to the outer end of the positioning strip 3; the two positioning strips 3 are arranged in parallel, and the positioning strips 3 are arranged in a close contact with the inner wall of the drawer groove, the guide block 4 is embedded in the end of the positioning strip 3 and is provided with a roller, and the bottom of the drawer 1 is symmetrically provided with a balance bar 6, and the balance bar 6 is inserted with a guide rod 7, and the inner end of the guide rod 7 is fixed to the inner wall of the drawer groove;

[0022] It should be noted that the anti-sinking slide rail structure involved in the present application is used for the movable pulling and drawing of the drawer 1. By setting the guide rail structure, the drawer 1 can slide normally and avoid sinking in the sliding out state, which is convenient for the use of the drawer 1. In specific use, when the drawer 1 in the initial state is pulled outward along the drawer groove, the guide block 4 fixed relatively to the drawer 1 slides relative to the positioning bar 3. During the sliding process, the rollers installed at the protrusions of the guide block 4 rotate synchronously, and the balance bar 6 fixed at the bottom of the drawer 1 also moves relative to the guide rod 7. As the drawer 1 is continuously pulled out, the gravity generated by the part of the drawer 1 that is separated from the drawer groove will cause the guide block 4 to have a sinking tendency. However, due to the buckling effect of the protruding part of the guide block 4 and the groove of the positioning bar 3, and the auxiliary support effect of the guide rod 7 on the balance bar 6, the guide block 4 cannot produce an actual sinking displacement, so that it can move along a straight line, which is convenient for the drawer 1 to go in and out directly.

[0023] Among them Figure 1 As shown, a panel 2 is fixed to the outer end of the drawer 1, the panel 2 is buckled into the opening of the drawer slot, and the edge of the panel 2 is arranged in a groove shape;

[0024] It should be noted that the panel 2 is used to cover the end of the drawer 1 and to cover the internal structure of the drawer groove. The groove area provided on the edge of the panel 2 is used to facilitate the user to pull out and open the drawer 1.

[0025] Among them Figure 2 As shown, the mounting block 5 is embedded in the inner wall of the drawer slot, the bottom of the balancing bar 6 is in contact with the bottom side of the drawer slot, and the circular channel in the middle of the balancing bar 6 is in transitional fit with the guide rod 7;

[0026] It should be noted that: the mounting block 5 is used to fix the position of the positioning bar 3, so that the positioning bar 3 and the drawer groove remain fixed, and the embedded mounting block 5 can reduce the space occupied by the drawer groove. After the balancing bar 6 is fitted with the bottom of the drawer groove, the friction damping generated between the drawer groove and the balancing bar 6 is used to assist in balancing the position of the drawer 1. The transition fit between the circular channel in the middle of the balancing bar 6 and the guide rod 7 will reduce the damping of the balancing bar 6 when it moves with the drawer 1, and will not affect the stability between the guide rod 7 and the balancing bar 6.

[0027] Among them Figure 3 As shown, the groove arranged on the side of the positioning strip 3 cooperates with the raised edge of the guide block 4, and the inner wall of the guide block 4 fits with the outer wall of the positioning strip 3; the roller is fixed to the raised end of the guide block 4, and the circumference of the roller is movably fitted to the groove surface of the positioning strip 3; the positioning strip 3 is a hollow structure, and the positioning strip 3 is arranged parallel to the guide rod 7;

[0028] It should be noted that the groove arranged on the side of the positioning strip 3 is of irregular shape. When the protrusion of the guide block 4 cooperates with the groove, the guide block 4 cannot be offset from the positioning strip 3 in the vertical direction and can only move in a straight line along the direction of the positioning strip 3. At the same time, to facilitate the linear displacement of the guide block 4 relative to the positioning strip 3, a roller is arranged in the gap between the protrusion of the guide block 4 and the groove of the positioning strip 3. The roller is used to assist the movement of the guide block 4 and reduce the friction damping of the guide block 4 during the movement. In order to increase the space utilization, the inner wall of the guide block 4 is fitted with the side of the positioning strip 3. At the same time, in order to reduce the load-bearing of the guide rail structure, the positioning strip 3 is set to a hollow structure. The drawer 1 moves stably in a straight line under the dual restrictions of the positioning strip 3 and the guide rod 7.

[0029] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make some simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
