[0021] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0022] like Figure 1 As shown, this embodiment of the guardrail provides a specific implementation, including: a telescopic frame 1, the telescopic frame 1 having at least two symmetrical telescopic rods 103. A fixed guardrail 2 and a movable guardrail 3 are provided between the two telescopic rods 103, the fixed guardrail 2 being fixedly connected to one end of the telescopic rod 103, and the movable guardrail 3 being slidably connected between the two telescopic rods 103.
[0023] Specifically, in this embodiment, the telescopic frame 1 further includes an upper crossbeam 101 and a lower crossbeam 102, with the fixed sections and telescopic ends of two symmetrical telescopic rods 103 respectively connected to the upper crossbeam 101 and the lower crossbeam 102. The upper end of the fixed guardrail 2 is fixedly connected to the upper crossbeam 101.
[0024] like Figure 2 As shown, the movable guardrail 3 has an open state that overlaps at least partially with the fixed guardrail 2.
[0025] like Figure 1 , Figure 3 As shown, in this embodiment, both the fixed guardrail 2 and the movable guardrail 3 have at least a portion of metal mesh. The fixed guardrail 2 has protrusions 201. When the movable guardrail 3 is opened, the protrusions 201 engage with the mesh openings of the metal mesh of the movable guardrail 3, thereby fixing the movable guardrail 3 in place. Figure 2 The state shown is the on state.
[0026] Of course, the above description is not limiting. In some alternative embodiments, at least a portion of the movable guardrail 3 is a metal mesh, and the fixed guardrail 2 has protrusions 201 that engage with the mesh openings of the metal mesh when the movable guardrail 3 is opened. Additionally, in some alternative embodiments, at least a portion of the fixed guardrail 2 is a metal mesh, and the movable guardrail 3 has protrusions 201 that engage with the mesh openings of the metal mesh when the movable guardrail 3 is opened.
[0027] like Figure 1 , Figure 3 As shown, in this embodiment, the protrusion 201 is a structure formed by bending one of the metal strips of the metal mesh. Specifically, the metal mesh includes longitudinal metal strips 4, the extension direction of which is parallel to the sliding direction of the movable guardrail 3, and the protrusion 201 is formed on at least a portion of the longitudinal metal strips 4. This arrangement facilitates the protrusion 201 to be inserted into the mesh openings of the metal mesh through deformation. After the protrusion 201 is inserted into the mesh openings, it generates a certain fastening force, making the movable guardrail 3 tightly connected to the fixed structure.
[0028] Furthermore, in this embodiment, the longitudinal metal strip 4 with the protrusion 201 is staggered from the other longitudinal metal strips 4. This arrangement prevents interference between the longitudinal metal strip 4 with the protrusion 201 and the other longitudinal metal strips 4 when the movable guardrail 3 moves.
[0029] like Figure 1As shown, in this embodiment, the metal mesh includes horizontal metal strips 5, the extension direction of which is perpendicular to the sliding direction of the movable guardrail 3. This arrangement, with the horizontal metal strips 5 and the vertical metal strips 4 forming a grid structure, significantly enhances the overall rigidity of the metal mesh.
[0030] Furthermore, in this embodiment, at least some of the transverse metal strips 5 have hook structures 6 formed at both ends, and the hook structures 6 are slidably connected to the telescopic rod 103. This arrangement simplifies the connection process between the metal mesh and the telescopic rod 103. During installation, the worker only needs to slip the hooks onto the telescopic rod 103 and slide them into place to complete the connection.
[0031] like Figure 4 As shown, in this embodiment, hook structures 6 are formed at both ends of the horizontal metal strip 5 near the movable guardrail 3 of the fixed guardrail 2. This arrangement allows the end of the fixed guardrail 2 near the movable guardrail 3 to slide relative to the telescopic rod 103. Therefore, when the telescopic rod 103 extends or retracts, the fixed guardrail 2 can move synchronously with the telescopic rod 103.
[0032] like Figure 5 As shown, in this embodiment, the movable guardrail 3 has hook structures 6 formed at both ends of the two horizontal metal bars 5 near the fixed guardrail 2 and at the ends away from the fixed guardrail 2. This arrangement allows the movable guardrail 3 to slide stably on the telescopic rod 103.
[0033] like Figure 4 , Figure 5 As shown, in this embodiment, the diameter of the transverse metal strip 5 used to form the hook structure 6 is larger than the diameter of the other transverse metal strips 5. The increased diameter helps improve the overall rigidity of the movable guardrail 3. This enhanced rigidity allows the movable guardrail 3 to more effectively resist bending and twisting when subjected to external forces, maintaining its original shape and position. This improves the efficiency of the connection between the movable guardrail 3 and the fixed guardrail 2. When the protrusion 201 on the fixed guardrail 2 comes into contact with the transverse metal strip on the movable guardrail 3, the elastic deformation of the protrusion can reduce the deformation of the thicker transverse metal strip 5.
[0034] like Figure 1 , Figure 4 As shown, in this embodiment, the protrusions 201 are located at the end of the fixed guardrail 2 away from the movable guardrail 3, and there are two protrusions spaced apart. This arrangement improves the stability of locking the movable guardrail 3.
[0035] In addition, in some alternative embodiments, the movable guardrail 3 has a plurality of protrusions spaced apart at one end away from the fixed guardrail 2, and the line connecting the plurality of protrusions 201 is perpendicular to the sliding direction of the movable guardrail 3.
[0036] Working principle: like Figure 1 As shown, when the movable guardrail 3 slides down to close, it can remain closed under the action of gravity.
[0037] like Figure 2 As shown, when the movable guardrail 3 slides upward to open, the protrusion 201 engages with the mesh of the metal mesh, maintaining this open state and facilitating pet entry and exit. In this state, sliding the movable guardrail 3 downward to pop the protrusion 201 out of the mesh of the metal mesh restores the movable guardrail 3 to its closed state.
[0038] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the present invention.
