Description

Technical Field

[0001] This utility model belongs to the technical field of windproof curtains or tents, and in particular relates to a lifting and guiding device for windproof curtains. Background Technology

[0002] Currently, windproof curtains used in workshops or tents are installed on both sides within guide grooves on the side columns (equivalent to door frames) to prevent lateral movement of the windproof curtain and achieve the purpose of wind protection and blocking. However, since the guide grooves are formed by installing separate mounting columns on the columns, and the installation and positioning of the mounting columns are achieved by manual measurement, measurement errors can easily lead to errors in the mounting columns or grooves on both sides, causing the windproof curtain to be obstructed from sliding up and down, thus affecting the normal use of the windproof curtain. Summary of the Invention

[0003] The purpose of this invention is to provide a lifting and guiding device for a windproof curtain with accurate positioning of the mounting column.

[0004] The purpose of this utility model is to solve the following problem:

[0005] A lifting and guiding device for a windproof curtain includes a frame consisting of a crossbeam and columns. Each of the two opposite sides of two adjacent columns is provided with one or more vertical grooves or protrusions. The inner side of the mounting column is provided with protrusions or grooves that cooperate with the vertical grooves or protrusions, and the outer side is provided with vertical sliding grooves on the lower ends of the windproof curtain, allowing the sliders to slide up and down inside. After the protrusions or grooves of the mounting column are engaged with the vertical grooves or protrusions of the columns, the mounting column is fixed to the columns by screws or bolts.

[0006] As a further optimization of the above technical solution, the crossbeam has four beams connected in sequence to form a rectangular frame, and the uprights extending downwards are installed at the four corners of the rectangular frame.

[0007] As a further optimization of the above technical solution, one or more vertical grooves or protrusions are provided on each of the adjacent two sides of the column. The inner side of the mounting column is provided with a protrusion or groove that cooperates with the vertical groove or protrusion, and the outer side is provided with a vertical sliding groove on the side of the windproof curtain that can slide up and down inward. After the protrusion or groove of the mounting column is engaged with the vertical groove or protrusion of the column, the mounting column is fixed to the column by screws or bolts. The lower end face of the column is provided with a base.

[0008] In a further optimization of the above technical solution, the column is provided with threaded holes at intervals in the vertical direction, and the mounting column is provided with mounting holes at intervals in the vertical direction opposite to the threaded holes. Screws or bolts pass through the mounting holes and are screwed into the threaded holes to fix the mounting column to the column.

[0009] As a further optimization of the above technical solution, the outer side of the mounting hole is enlarged to form a groove into which the large head of the screw or bolt is embedded.

[0010] As a further optimization of the above technical solution, the sliders on both sides of the roller shutter or telescopic windproof curtain are slidably installed in two grooves on the mounting columns of two adjacent columns.

[0011] As a further optimization of the above technical solution, the curtain fabric of the windproof curtain is a mesh screen.

[0012] As a further optimization of the above technical solution, the mounting column is made of profiles made of aluminum alloy, stainless steel, ordinary carbon steel, or engineering plastics.

[0013] As a further optimization of the above technical solution, the column is made of profiles made of aluminum alloy, stainless steel, ordinary carbon steel, or engineering plastic materials.

[0014] The advantages of this invention compared to the prior art are:

[0015] 1. The crossbeam and the column of this utility model are fixedly connected, which ensures the verticality or parallelism of the columns on both sides. Since the vertical groove or protrusion on the column is engaged in the protrusion or vertical groove of the mounting column, the verticality or parallelism of the sliding groove on the mounting column on both sides is also ensured, thereby making the windproof curtain slide smoothly up and down along the sliding groove.

[0016] 2. Because the upright and the mounting column are positioned by the interlocking of the vertical groove and the protrusion, the stability of the lateral positioning of the mounting column relative to the upright is increased.

[0017] 3. This utility model has a simple structure, is easy to install, and has good positioning stability, making it suitable for the lifting and guiding of windproof curtains. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figures 1-5 :

[0024] A lifting and guiding device for a windproof curtain includes a frame consisting of a crossbeam 40 and a column 10. Each of the two opposite sides 12 of two adjacent columns 10 has one or more vertical grooves 13 or protrusions. The inner side 21 of the mounting column 20 has protrusions 23 or vertical grooves that cooperate with the vertical grooves 13 or protrusions, and the outer side 22 has vertical sliding grooves 24 on which sliders 31 at both ends of the lower side of the windproof curtain can slide up and down. After the protrusions 23 or vertical grooves of the mounting column 20 are engaged with the vertical grooves 13 or protrusions of the column 10, the mounting column 20 is fixed to the column 10 by screws or bolts. The relative limiting of the vertical grooves and protrusions improves the stability of the lateral positioning of the column and the mounting column, reducing the force required for the screws or bolts to limit the movement. The screws or bolts are merely connecting elements and do not bear the thrust of the windproof curtain on the mounting column; instead, the force is transmitted through the protrusions or vertical grooves on the mounting column to the vertical grooves or protrusions on the column.

[0025] As a further optimization of the above technical solution, the crossbeam 40 has four beams connected sequentially to form a rectangular frame (see...). Figure 1 The rectangular frame has downward-extending columns 10 installed at its four corners.

[0026] As a further optimization of the above technical solution, the two adjacent sides 11 and 12 of the column 10 are provided with one or more vertical grooves 13 or protrusions. The inner side of the mounting column 20 is provided with a protrusion 23 or vertical groove that cooperates with the vertical groove 13 or protrusion. The outer side 22 is provided with a vertical sliding groove 24 for the slider 31 of the windproof curtain to slide up and down. After the protrusion 23 or vertical groove of the mounting column 20 is engaged with the vertical groove 13 or protrusion of the column 10, the mounting column 20 is fixed to the column 10 by screws or bolts. The lower end face of the column 10 is provided with a base 50.

[0027] In a further optimization of the above technical solution, the column 10 is provided with threaded holes at intervals in the vertical direction, and the mounting column 20 is provided with mounting holes at intervals in the vertical direction opposite to the threaded holes. Screws or bolts pass through the mounting holes and are screwed onto the threaded holes to fix the mounting column 20 to the column 10.

[0028] As a further optimization of the above technical solution, the outer side of the mounting hole is enlarged to form a groove into which the large head of the screw or bolt is embedded.

[0029] As a further optimization of the above technical solution, the sliders on both sides of the roller shutter or telescopic windproof curtain are slidably installed in two grooves 24 on the mounting columns 20 of the two adjacent columns 10.

[0030] As a further optimization of the above technical solution, the curtain of the windproof curtain is a mesh screen, which has a certain wind-blocking performance and can also block some dust and / or mosquitoes and flies.

[0031] As a further optimization of the above technical solution, the mounting column 20 is a profile made of aluminum alloy, stainless steel, ordinary carbon steel, or engineering plastic.

[0032] As a further optimization of the above technical solution, the column 10 is a profile made of aluminum alloy, stainless steel, ordinary carbon steel, or engineering plastic material.

[0033] In use, the roller blind or telescopic curtain is placed in the mounting cavity on the lower end face of the crossbeam 40. The lower edge of the curtain is fixed on the lower crossbar 30. The sliders 31 at both ends of the lower crossbar 30 are slidably placed in the sliding groove 24. Pulling the lower crossbar 30 up and down can move the curtain up and down to open or close the side door.
