Description

Technical Field

[0001] The present invention relates to the field of molds, and particularly to a fireproof plugging mold for cable trays. Background Art

[0002] During the electrical installation construction process of building engineering, there is no simple and effective plugging method for steel cable trays passing through fire partitions. There are often problems such as poor sealing and falling of fire pillows, or the fireproof boards cut and clamped in the cable trays are prone to breakage and falling off, making it difficult to guarantee the quality of fireproof plugging, and the forming effect is poor. If the fireproof plugging is not tight, a chimney effect will occur in the cable tray during a fire, causing the fire to spread rapidly to other areas, seriously affecting people's lives and property safety. Using this fireproof plugging tool can effectively solve the problems of poor sealing, unattractive appearance, and difficult-to-guarantee fireproof plugging quality. Therefore, we propose a fireproof plugging mold for cable trays. Summary of the Invention

[0003] The main purpose of the present invention is to provide a fireproof plugging mold for cable trays, which can effectively solve the problems in the background art.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0005] A fireproof plugging mold for cable trays, comprising:

[0006] A cable tray, with guard plates installed on both inner walls thereof, and two screw rods connected between the two groups of guard plates by bolts;

[0007] A cable, which passes through between the cable tray and the screw rods, and

[0008] Metal clamping plates, several groups of metal clamping plates are arranged side by side between the two groups of guard plates, and the metal clamping plates are sleeved outside the two screw rods through through-holes opened on their surfaces.

[0009] Preferably, a strong magnetic plate is installed inside the guard plate, and the strong magnetic plate adsorbs on the inner wall of the cable tray.

[0010] Preferably, the diameter of the screw rod is equal to the width of the through-hole.

[0011] Preferably, two parallel limiting plates are connected between the two groups of guard plates, and the two limiting plates are respectively located above and below the metal clamping plates, and the metal clamping plates are in an "I" shape.

[0012] Preferably, anti-slip pads are bonded to the sides of the two limiting plates facing the metal clamping plates.

[0013] Preferably, an elastic band is installed at one end of the metal clamping plate facing the inner side of the cable tray, and an airbag is installed inside the elastic band, and connecting bands are adhered to the outside of the multiple groups of elastic bands.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] First, it is made by using galvanized steel sheets, through screws, and neodymium magnets. First, select the appropriate type of fireproof plugging tool according to the specifications of the cable tray. After the cables in the cable tray are laid, select the appropriate type of fireproof plugging tool, clamp the fireproof plugging tool at the part of the cable tray that needs fireproof plugging for profiling. After profiling, cut off the protruding part. After cutting, the width of the fireproof plugging tool is the same as the depth of the cable tray. Clamp it in the cross-section of the cable tray and fix it on the inner side wall of the cable tray by the adsorption of neodymium magnets, and the installation of the fireproof plugging tool for this cable tray is completed;

[0016] Second, by setting an elastic band at one end of the metal splint and a connecting band outside the elastic band, the fit between the metal splint and the surface of the cable can be improved, thereby ensuring the mold accuracy of the mold production. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Among them, the same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0024] Referring to Figures 1-4 as shown, a fireproof plugging mold for a cable tray includes:

[0025] A cable tray 1, on both inner walls of which guard plates 2 are installed, and two groups of screws 3 are connected between the two groups of guard plates 2 by bolts;

[0026] A cable 6 passes through between the bridge 1 and the lead screw 3, and

[0027] Metal clamping plates 4, several groups of metal clamping plates 4 are arranged side by side between two groups of protective plates 2, and the metal clamping plates 4 are sleeved outside two groups of lead screws 3 through through grooves opened on their surfaces.

[0028] Refer to Figure 2 As shown, a strong magnetic plate 7 is installed inside the protective plate 2 and is adsorbed on the inner wall of the bridge 1 by the strong magnetic plate 7.

[0029] Refer to Figure 3 and Figure 4 The diameter of the lead screw 3 is equal to the width of the through hole.

[0030] Refer to Figure 1 and Figure 4 As shown, two groups of parallel limiting plates 5 are connected between two groups of protective plates 2, and the two groups of limiting plates 5 are respectively located on the upper and lower sides of the metal clamping plate 4, and the metal clamping plate 4 is in an "I" shape.

[0031] Refer to Figure 1 One side of the two groups of limiting plates 5 facing the metal clamping plate 4 is bonded with an anti-slip pad.

[0032] Refer to Figure 4 As shown, one end of the metal clamping plate 4 facing the inner side of the bridge 1 is provided with an elastic band 8, and an airbag 9 is installed inside the elastic band 8, and connecting bands 10 are adhered to the outside of multiple groups of elastic bands 8.

[0033] During use, make the cable 6 (or other items) to be blocked pass through between the lead screw 3 and the bridge 1, and then push the metal clamping plate 4 towards the cable 6, so that the metal clamping plate 4 is distributed around the surface of the cable 6. After completion, it forms a shape as shown in Figure 2 After that, cut off the protruding part of the metal clamping plate 4. After cutting, the formed shape of the metal clamping plate 4 is the same as the surface shape of the cable 6. Secondly, when the position between the metal clamping plates 4 changes, due to the self-elastic force of the elastic band 8 outside the metal clamping plate 4, it can not only block the gap between the metal clamping plates 4, but also make the connecting band 10 outside the metal clamping plate 4 fit the outer wall of the cable 6, avoiding that a certain metal clamping plate 4 cannot fit tightly with the surface of the cable 6, and further improving the sealing performance between the metal clamping plate 4 and the cable 6.
