[0018] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0019] Reference Figure 1-5 The utility model is a splicing grille with automatic telescopic function, which includes: a grille plate 1, a plurality of protrusions 4 arranged in an orderly manner are arranged on the lower surface of the grille plate 1, and the protrusions 4 form an orderly groove structure on the lower surface of the grille plate 1, so as to reduce the contact area between the grille plate 1 and its installation position, and improve the drainage effect of the grille plate 1 after installation. When docking the grilles, multiple grille plates 1 are in close contact, and the contacting sides of multiple grille plates 1 are all provided with a mother-and-child docking mechanism 2, which is composed of a docking opening 10 and a docking buckle 11, and the docking buckle 11 is fixedly connected to the grille plate 1, and the docking buckle 11 is staggered with the docking opening 10. Distribution, a protrusion 12 is fixedly connected to the docking buckle 11 at a position away from the center point of the grille plate 1, and the sum of the width of the protrusion 12 and the docking buckle 11 is greater than the width of the docking opening 10. The parent-child docking mechanism 2 cooperates with the protrusion 12 to provide a stretching and separation range for the grille after docking, thereby improving the flexibility and convenience of the grille when in use. The detachable mechanism can reduce the stress concentration effect of the grille when in use, and can extend the service life of the grille. The protrusion 12 serves as a limiter of the docking buckle 11, thereby limiting the stretching range of the grille and avoiding the situation where the stability of the grille is reduced due to excessive stretching of the grille.

[0020] Two limiting sleeves 8 are arranged at the lower end of the grille plate 1. When the grille is docked, the docking buckle 11 is located inside the limiting sleeve 8. The limiting sleeve 8 and the block 7 are both made of modified plastic. The material of the connecting plate 9 is the same as that of the grille plate 1. The limiting sleeve 8 directly receives the docking buckle 11 to limit the range of movement of the docking buckle 11, ensuring that the docking buckle 11 can only slide in translation during the process of stretching the grille, thereby reducing the sliding deviation of the grille during the process of stretching and separating, and improving the smoothness of separating the grille. A connecting plate 9 is fixedly connected between the two limiting sleeves 8 to connect The upper end of the plate 9 is slidably connected to the protrusion 4, and the connecting plate 9 integrates the two limit sleeves 8 to improve the convenience of moving the limit sleeves 8. The connecting plate 9 is fixedly connected with an adjusting member 3 at a position away from the center point of the grille plate 1. When docking the grilles, the end of the adjusting member 3 away from the connecting plate 9 is clamped with the connecting plate 9 in the other grille plate 1. The adjusting member 3 utilizes the characteristics of the spring rod 6 to facilitate the user to change the position of the limit sleeve 8 externally, wherein the limit sleeve 8, the connecting plate 9, and the adjusting member 3 cooperate with each other to form a reinforcement assembly to improve the sliding stability of the grilles during the stretching and separation of multiple grilles.

[0021] The adjusting member 3 is composed of a telescopic rod 5 and two spring rods 6. The two spring rods 6 are fixedly connected to both ends of the telescopic rod 5. One end of the spring rod 6 away from the telescopic rod 5 is fixedly connected with a clamping block 7. The clamping block 7 is located inside the connecting plate 9. The side surface of the spring rod 6 is provided with a limiting groove 13, and the protrusion 4 is located inside the limiting groove 13. The telescopic rod 5 part of the adjusting member 3 is convenient for changing the position of the limiting sleeve 8 outside the grille, and the existence of the spring rod 6 provides bending ability for the telescopic rod 5 and the limiting sleeve 8 after docking, thereby reducing the influence of the telescopic rod 5 on the function of the spliced ​​grille to be stretched on all four sides at the same time, wherein the telescopic rod 5 has its own return groove.

[0022] Working principle: firstly, the grille plate 1 is docked by using the parent-child docking mechanism 2 and the adjusting part 3, and then the adjusting part 3 is clamped with the connecting plate 9 of another grille plate 1, and the telescopic rod 5 is used to drive the connecting plate 9 to slide in the direction of the contraction of the telescopic rod 5, so that the limit sleeve 8 is close to and accommodates the docking buckle 11, thereby limiting the range of motion of the docking buckle 11 and reducing the displacement of the grille when the docking grille is stretched and separated, and the telescopic rod 5 can move with the separation of the grille, thereby reducing the influence of the reinforcement component on the smoothness of the grille separation, and when the grille is stretched on all four sides, the spring rods 6 at both ends of the telescopic rod 5 are tilted by the force, thereby reducing the influence of the inability of the telescopic rod 5 to bend on the stretching effect of the grille on all four sides.

[0023] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
