Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mounting combined devices, in particular to a drawer slide rail with a locking function. Background Art
[0002] Traditional slide rails generally include an upper rail, a middle rail, and a lower rail. The lower rail is installed on the left and right sides of the cabinet, and the upper rail is installed on the left and right sides of the drawer. The middle rail serves as a load-bearing rail, which is slidably connected between the upper rail and the lower rail to extend the range of motion of the drawer to stretch outward.
[0003] However, traditional slide rails have the following shortcomings in practical applications:
[0004] 1) As the application of slide rails becomes more and more extensive, the length of slide rails in many large drawer applications is getting longer and longer, resulting in a large inertial impact force during the opening process of the slide rails, causing loud noise, and even unbalanced supporting force on both sides of the slide rails. Long-term uneven force operation causes different degrees of wear on both sides of the slide rails, reducing the smoothness and stability of the slide rails opening and closing.
[0005] 2) Although the drawer is large, it only needs to be opened a short distance during many uses. However, it is still subject to inertial impact during the opening process. At the same time, due to the lack of support from the front section, long-term use will cause the upper rail to deform, affecting the normal opening and closing of the product.
[0006] 3) During actual use, the drawer will move back and forth due to the action of the slide rail, making it inconvenient to take out. Utility Model Content
[0007] The purpose of the invention of the utility model is to overcome the shortcomings of the prior art and provide a drawer slide with a locking function. The drawer slide has a simple structure and has a front and rear locking effect to prevent front and rear movement, making it convenient to take items, and effectively solve the problem of loud noise caused by inertial impact force, thereby improving the smoothness and stability of operation, reducing the probability of deformation during use, and ensuring the normal operation of the product.
[0008] The invention objective of the utility model is achieved as follows: a drawer slide rail with a locking function comprises an upper rail, a middle rail and a lower rail which are slidably connected in sequence, wherein a locking device is arranged between the upper rail and the lower rail, the locking device comprises a locking block, a front stop block and a rear stop block, the locking block is mounted on the lower rail, the front stop block and the rear stop block are respectively mounted on the front end portion and the rear end portion of the upper rail, and the front stop block and the rear stop block are locked and connected with the locking block or unlocked and separated while being squeezed and deformed as the upper rail slides.
[0009] According to the above optimization, the front and rear ends of the locking block are respectively provided with a front buckle part, a locking protrusion and a rear buckle part, the front buckle part is buckled on the front port of the lower rail, and one side of the lower rail is provided with a buckle block that is buckled with the rear buckle part, the locking protrusion is arranged between the front buckle part and the rear buckle part, and the locking protrusion moves relative to the upper rail to be locked and connected or unlocked and separated with the front stop block or the rear stop block.
[0010] According to the above optimization, guide protrusions are respectively provided between the locking protrusion and the front buckle portion and the rear buckle portion for the front stop block and the rear stop block to slide in a directional manner to the locking protrusion.
[0011] According to the above optimization, one side of the upper rail is provided with a front clamping block and a rear clamping block for buckling with the front stop block and the rear stop block, and the front stop block and the rear stop block are respectively provided with assembly buckles for buckling with the front clamping block and the rear clamping block.
[0012] According to the above optimization, the front stop block and the rear stop block are respectively provided with a deformable elastic stop portion which can be deformed up and down by being squeezed, and the deformable elastic stop portion is locked and connected with or unlocked and separated from the stop block as the upper rail moves.
[0013] According to the above optimization, the deformable elastic stop portion has a buffer space for multi-stage buffer deformation.
[0014] The advantages of the utility model are:
[0015] 1) The locking block, front stop block and rear stop block of the locking device are coordinated, and the structure is simple. During the opening and closing of the drawer, the upper rail moves accordingly, so that the front stop block or the rear stop block is connected or unlocked and separated from the locking block lock, which has a front and rear locking effect, prevents front and rear movement, and is convenient for taking items.
[0016] 2) With the structural coordination of the front stop block and the rear stop block, a locking function can be provided when a larger drawer is opened a short distance. At the same time, the front support force is assisted to prevent the upper rail from deforming due to a large load, thereby meeting the use requirements of a larger drawer and ensuring the normal opening and closing of the product.
[0017] 3) The front and rear stop blocks have their own structural characteristics, which effectively solves the problem of high noise caused by inertial impact force. Combined with the structure of the locking block, the smoothness and stability of the opening and closing of the slide rail are guaranteed, thereby ensuring the quality of product use.

[0024] The utility model is further described below in conjunction with the accompanying drawings.
[0025] According to the attached Figures 1 to 6 As shown, the drawer slide rail with locking function of the utility model comprises an upper rail 1, a middle rail 2 and a lower rail 3 which are slidably connected in sequence. A locking device is provided between the upper rail 1 and the lower rail 3. The locking device comprises a locking block 4, a front stop block 5 and a rear stop block 6. The locking block 4 is installed on the lower rail 3. The front stop block 5 and the rear stop block 6 are installed at the front end and the rear end of the upper rail 1 respectively. The front stop block 5 and the rear stop block 6 are locked and connected with the locking block 4 or unlocked and separated while being squeezed and deformed as the upper rail 1 slides.
[0026] The locking device has a simple structure with the locking block 4, the front stop block 5 and the rear stop block 6. The upper rail 1 can move with it during the opening and closing of the drawer, so that the front stop block 5 or the rear stop block 6 is locked or unlocked and separated with the locking block 4, which has a front and rear locking effect, prevents front and rear movement, facilitates the taking of items, and effectively solves the problem of loud noise caused by inertial impact force, ensures the smoothness and stability of the opening and closing of the slide rail, and ensures the quality of product use.
[0027] Reference Figures 1 to 6 As shown, in further detail, the front and rear ends of the locking block 4 are respectively provided with a front buckle 41, a locking protrusion 42 and a rear buckle 43. The front buckle 41 is buckled on the front end of the lower rail 3, and one side of the lower rail 3 is provided with a buckle block 31 that is buckled with the rear buckle 43. The locking protrusion 42 is arranged between the front buckle 41 and the rear buckle 43, and the locking protrusion 42 moves relative to the upper rail 1 to be locked and connected with the front stop block 5 or the rear stop block 6 or unlocked and separated.
[0028] The front stop block 5 and the rear stop block 6 are respectively provided with a deformable elastic stop portion 10 which can be deformed up and down by being squeezed. The deformable elastic stop portion 10 is locked and connected with the stop block 4 or unlocked and separated as the upper rail 1 moves.
[0029] When the drawer is opened, the upper rail 1 moves accordingly. When the drawer is opened to a short distance, the deformable elastic stopper 10 of the front stopper 5 is squeezed and deformed by the locking protrusion 42 of the locking block 4, so that the deformable elastic stopper 10 of the front stopper 5 is locked on the locking protrusion 42, so that the drawer obtains an effective locking function, and at the same time has support assistance, reducing the probability of deformation of the upper rail 1 due to a large load. When the drawer continues to be opened, a sufficiently large external force is applied to pull the drawer outward, so that the deformable elastic stopper 10 of the front stopper 5 can be deformed and separated from the locking protrusion 42 of the locking block, thereby achieving unlocking. At this time, the drawer can be further pulled outward, so that the deformable elastic stopper 10 of the rear stopper 6 is squeezed and deformed by the locking block, so that the full stopper is locked on the locking protrusion 42 of the locking block, achieving the locking function and having the assistance of the rear section support force, strengthening the structural stability, and extending the service life of the product.
[0030] In addition, the deformable elastic stopper 10 has a buffer space 11 for multi-stage buffer deformation, which effectively solves the problem of high noise caused by inertial impact force.
[0031] Reference Figures 1 to 6 As shown, in further detail, guide protrusions 44 are provided between the locking protrusion 42 and the front buckle 41 and the rear buckle 43, respectively, for the front stop block 5 and the rear stop block 6 to slide to the locking protrusion 42 in a directional manner, thereby improving the smoothness and stability of the slide rail and enhancing the locking effect.
[0032] In addition, one side of the upper rail 1 is provided with a front clamping block 7 and a rear clamping block 8 for buckling with the front stop block 5 and the rear stop block 6, and the front stop block 5 and the rear stop block 6 are respectively provided with an assembly buckle position 9 for buckling with the front clamping block 7 and the rear clamping block 8.
[0033] The structure of the locking block 4 can make it easy to disassemble and assemble the locking block 4 on the lower rail 3, and the assembly is convenient, the structure is stable, and the locking effect is ensured.
[0034] The above specific embodiments are only specific implementation methods with better effects of the utility model. Any structure that is the same or equivalent to the drawer slide rail with locking function of the utility model is within the protection scope of the utility model.
