Description

Technical Field

[0001] The utility model relates to the technical field of safety warning isolation devices, in particular to a safety warning isolation device for chemical safety. Background Art

[0002] In the production process of chemical plants, in order to separate the production area and prevent non-staff from entering the production area, fiberglass fences are generally used to isolate the production area. Fiberglass fences are made of pultruded fiberglass as structural profiles combined with fiberglass molded products. They have the advantages of high strength and corrosion resistance, and can adapt well to the chemical plant environment.

[0003] When the crossbars and posts of the existing FRP fence are assembled, the crossbars and posts are fixed by rivets. The stainless steel rivets produce an isolation film on the surface. Under normal circumstances, the stainless steel rivets are unlikely to corrode and rust. However, during the actual installation and use, the isolation film on the surface of the stainless steel rivets is easily damaged. Therefore, after the FRP fence is assembled, when it is used in a chemical plant, the stainless steel rivets are easily corroded and rusted, resulting in the service life of the FRP fence being affected. Based on this, a safety warning isolation device for chemical safety is provided. Utility Model Content

[0004] The purpose of the utility model is to provide a safety warning isolation device for chemical safety in order to solve the problems in the above background.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a safety warning isolation device for chemical safety, comprising a glass fiber reinforced plastic fence composed of a crossbar and a column, the top of the crossbar is provided with a mounting groove for the column to penetrate, and both sides of the outer wall of the column are provided with positioning holes matching the number of the crossbar in the vertical direction, and a buckle assembly is installed inside the mounting groove, and the buckle assembly is used to realize the connection and fixation between the crossbar and the column;

[0006] The buckle assembly includes a clamping unit and a shielding unit;

[0007] The clamping unit is clamped with the positioning hole to achieve the connection and fixation between the cross bar and the column;

[0008] The shielding unit is used to shield the clamping unit, so that the positioning hole on the outside of the column can smoothly pass through the clamping unit, so that the column can pass through multiple cross bars in sequence.

[0009] As a further solution of the utility model: the clamping unit includes an upper T-shaped rectangular sleeve, an S-shaped spring sheet, and a locking protrusion;

[0010] The S-shaped spring piece is symmetrically fixed on both sides of the bottom of the upper T-shaped rectangular sleeve, and the upper T-shaped rectangular sleeve is clamped to the inner side of the installation groove from the top of the cross bar. The S-shaped spring piece is clamped with the inner wall of the installation groove by the deformation reset of the arc-shaped part of the upper half, so as to realize the installation limit of the upper T-shaped rectangular sleeve and the cross bar;

[0011] The locking protrusion is symmetrically fixed on one side of the arc-shaped parts of the lower halves of the two S-shaped spring sheets that are close to each other. The column is squeezed against the locking protrusion during the process of passing through the upper T-shaped rectangular sleeve, causing the arc-shaped part of the lower half of the S-shaped spring sheet to deform. When the positioning hole is aligned with the locking protrusion, the locking protrusion is inserted into the positioning hole under the action of the resetting elastic force of the arc-shaped part of the lower half of the S-shaped spring sheet, thereby realizing the connection and fixation between the column and the cross bar.

[0014] The downward convex rectangular sleeve is clamped on the inner side of the installation groove from the bottom of the cross bar, and the shielding sleeve contacts and presses the locking protrusion. When the locking protrusion is aligned with the positioning groove, it is clamped into the positioning groove to achieve the initial position fixation of the downward convex rectangular sleeve. The blocking sleeve blocks the locking protrusion, so that the positioning hole on the column can smoothly pass through the area where the locking protrusion is located.

[0015] As a further solution of the utility model: the shielding unit further includes a through groove;

[0016] The through grooves are symmetrically arranged on both sides of the outer wall of the shielding sleeve, and the through grooves are located below the positioning grooves and penetrate to the inner side of the shielding sleeve;

[0017] When the lower convex rectangular sleeve is pushed to continue to move upward so that the locking protrusion is aligned with the through groove, the locking protrusion passes through the through groove and engages with the positioning hole to fix the position of the column.

[0018] As a further solution of the utility model: the upper T-shaped rectangular sleeve, S-shaped spring piece, and locking protrusion are integrally formed by injection molding, and the lower convex rectangular sleeve, shielding sleeve, positioning groove, and through-groove are integrally formed by injection molding.

[0026] 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 described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0027] See also Figures 1 to 4 In the embodiment of the utility model, a safety warning isolation device for chemical safety includes a glass fiber reinforced plastic fence 1 composed of a cross bar 101 and a column 102. The top of the cross bar 101 is provided with a mounting groove 103 for the column 102 to pass through. Both sides of the outer wall of the column 102 are provided with positioning holes 104 in the vertical direction that match the number of the cross bar 101. A buckle assembly 2 is installed on the inner side of the mounting groove 103. The buckle assembly 2 is used to realize the connection and fixation between the cross bar 101 and the column 102;

[0028] The buckle assembly 2 includes a clamping unit and a shielding unit;

[0029] The clamping unit is clamped with the positioning hole 104 to achieve the connection and fixation between the crossbar 101 and the column 102;

[0030] The shielding unit is used to shield the clamping unit, so that the positioning hole 104 on the outside of the column 102 can smoothly pass through the clamping unit, so that the column 102 can pass through the multiple cross bars 101 in sequence;

[0031] The clamping unit includes an upper T-shaped rectangular sleeve 201, an S-shaped spring piece 202, a locking protrusion 203, and a through slot 207;

[0032] The S-shaped spring piece 202 is symmetrically fixed on both sides of the bottom of the upper T-shaped rectangular sleeve 201. The upper T-shaped rectangular sleeve 201 is clamped to the inner side of the installation groove 103 from the top of the cross bar 101. The S-shaped spring piece 202 is clamped to the inner wall of the installation groove 103 by the deformation reset of the upper arc part, which is used to realize the installation limit of the upper T-shaped rectangular sleeve 201 and the cross bar 101.

[0033] The locking protrusion 203 is symmetrically fixed to the side where the arc-shaped parts of the lower halves of the two S-shaped spring sheets 202 are close to each other. When the column 102 passes through the upper T-shaped rectangular sleeve 201, it is squeezed by the locking protrusion 203, so that the arc-shaped part of the lower half of the S-shaped spring sheet 202 is deformed. When the positioning hole 104 is aligned with the locking protrusion 203, the locking protrusion 203 is clamped into the positioning hole 104 under the action of the resetting elastic force of the arc-shaped part of the lower half of the S-shaped spring sheet 202, so as to realize the connection and fixation between the column 102 and the crossbar 101;

[0034] The shielding unit includes a downward convex rectangular sleeve 204, a shielding sleeve 205, and a positioning groove 206;

[0035] The shielding sleeve 205 is fixed to the top of the downward convex rectangular sleeve 204, and the positioning groove 206 and the through groove 207 are symmetrically arranged on both sides of the outer wall of the shielding sleeve 205. The through groove 207 is located below the positioning groove 206 and penetrates to the inner side of the shielding sleeve 205;

[0036] The downward convex rectangular sleeve 204 is clamped to the inner side of the installation groove 103 from the bottom of the cross bar 101, and the shielding sleeve 205 contacts and presses the locking protrusion 203. When the locking protrusion 203 is aligned with the positioning groove 206, it is clamped into the positioning groove 206 to achieve the initial position fixation of the downward convex rectangular sleeve 204. The shielding sleeve 205 blocks the locking protrusion 203, so that the positioning hole 104 on the column 102 can smoothly pass through the area where the locking protrusion 203 is located.

[0037] When the downward convex rectangular sleeve 204 is pushed to continue to move upward to align the locking protrusion 203 with the through slot 207 , the locking protrusion 203 passes through the through slot 207 and engages with the positioning hole 104 to fix the position of the column 102 .

[0038] In this embodiment, it should be supplemented that: the crossbar 101 and the column 102 are made of glass fiber reinforced plastics, the mounting groove 103 and the positioning hole 104 are formed by later drilling, and the mounting groove 103 on the bottom crossbar 101 only penetrates the top of the crossbar 1, but not the bottom of the crossbar 1;

[0039] When assembling the crossbar 101 and the column 102, the buckle assembly 2 can be installed in the installation groove 103, and the operation steps are as follows:

[0040] First, insert the upper T-shaped rectangular sleeve 201 from the top of the cross bar 101 into the installation groove 103. At this time, the upper arc-shaped part of the S-shaped spring piece 202 is squeezed and deformed, so that the S-shaped spring piece 202 can be smoothly inserted into the cross bar 101. Then, the upper arc-shaped part of the S-shaped spring piece 202 is reset under its own elastic force, and the upper arc-shaped part of the S-shaped spring piece 202 is clamped with the edge of the installation groove 103 of the cross bar 101, so that the T-shaped rectangular sleeve 201 is installed and fixed;

[0041] Then, the downward convex rectangular sleeve 204 is inserted into the installation groove 103 from the bottom of the cross bar 101. At this time, the shielding sleeve 205 contacts and squeezes the end of the locking protrusion 203, so that the arc-shaped portion of the lower half of the S-shaped spring piece 202 is deformed. When the shielding sleeve 205 moves up to the positioning groove 206 and is aligned with the locking protrusion 203, the locking protrusion 203 is inserted into the positioning groove 206 under the resetting elastic force of the arc-shaped portion of the lower half of the S-shaped spring piece 202. At this time, the preliminary installation of the downward convex rectangular sleeve 204 is completed (it should be noted that: at this time, there is still a certain space between the bottom edge of the downward convex rectangular sleeve 204 and the lower surface of the cross bar 101);

[0042] After all the buckle components 2 are installed, the column 102 can be installed (it should be noted that: the installation groove 103 on the bottom crossbar 101 is only installed with the upper T-shaped rectangular sleeve 201), and the column 102 is inserted from the first crossbar 101 into the bottom crossbar 101. During this process, since the locking protrusions 203 in the upper crossbars 101 are blocked by the blocking sleeve 205, the column 102 can smoothly pass through the upper crossbars 101. Finally, the bottom of the column 102 is inserted into the crossbar 101. At this time, the column 102 and the locking protrusion 203 are formed. The arc-shaped portion of the lower half of the S-shaped spring piece 202 is squeezed to deform, so that the bottom of the column 102 can pass through the middle of the two locking protrusions 203. When the bottom of the column 102 fits with the bottom of the crossbar 101, the bottommost positioning hole 104 on the column 102 is aligned with the locking protrusion 203. At this time, the arc-shaped portion of the lower half of the S-shaped spring piece 202 is reset to make the locking protrusion 203 snap into the positioning hole 104, so that the connection between the column 102 and the bottommost crossbar 101 is achieved (it should be noted that at this time, the other positioning holes 104 on the column 102 are respectively aligned with the locking protrusions 203 in other crossbars 101);

[0043] Then, the lower convex rectangular sleeve 204 is pushed upward to align the through slot 207 with the locking protrusion 203. The locking protrusion 203 passes through the through slot 207 and other positioning holes 104 on the column 102 under the action of the elastic force of the arc-shaped portion of the lower half of the S-shaped spring piece 202 to be fixed, thereby achieving the connection and fixation of the column 102 with other cross bars 101.

[0044] Through the coordination of the above multiple parts, the column 102 and the cross bar 101 can be conveniently installed. Compared with the rivet fixing method, the installation efficiency is faster. The snap assembly 2 is made of corrosion-resistant plastic material as a whole, which can effectively avoid the problem of rivet corrosion and rust affecting the service life of the fiberglass fence, and thus better adapt to the production environment of the chemical plant.

[0045] Please refer to Figures 1 to 4 The upper T-shaped rectangular sleeve 201, the S-shaped spring piece 202, and the locking protrusion 203 are integrally formed by an injection molding process, and the lower convex rectangular sleeve 204, the shielding sleeve 205, the positioning groove 206, and the through groove 207 are integrally formed by an injection molding process.

[0046] In this embodiment, the processing technology of the buckle assembly 2 is simple, which is convenient for popularization and use, and effectively improves the assembly efficiency of the fiberglass reinforced plastic fence 1.

[0047] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
