Description

Technical Field

[0001] This utility model belongs to the field of power distribution cabinet installation technology, and specifically relates to a fireproof putty installation tool for power distribution cabinets. Background Technology

[0002] As a core device for power distribution and control, the lighting power supply box typically houses electrical components such as two-phase circuit breakers, single-phase fuses, and AC contactors. Power is transmitted and distributed via 2x2.5mm² cables. To ensure the safety of the electrical system and prevent the spread of fire, fire-retardant sealant must be used to seal the cable openings at the bottom of the lighting power supply box. This sealant not only effectively blocks flames and high temperatures, preventing fire from spreading to other areas through gaps in the box or cable openings, but also seals the cable openings, preventing dust and moisture from entering the box and affecting the normal operation of electrical components.

[0003] The conventional installation methods for fire-retardant putty have significant drawbacks. Traditionally, workers primarily use manual methods to apply the fire-retardant putty to the wire holes. This installation method is extremely inefficient, as each wire hole requires a significant amount of time for kneading and stacking the putty, which severely impacts construction progress, especially in large-scale projects or electrical cabinet installations with numerous wire holes. Furthermore, manual stacking makes it difficult to ensure the fire-retardant putty has a uniform shape, resulting in gaps between the putty and the wire holes, reducing its fire-resistant and sealing effects. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a fireproof putty installation tool for power distribution cabinets. This utility model achieves efficient, convenient, reliable, and highly applicable fireproof putty installation through a detachable jacket structure, convenient connecting components, adjustable diameter design, and special shell shape.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A fireproof putty installation tool for a power distribution cabinet includes a first sleeve and a second sleeve, which are detachably connected by a rotating connection assembly. The first sleeve and the second sleeve are mirror images of each other and form a shell structure with openings at the bottom and top. A first handle is connected to the first sleeve and a second handle is connected to the second sleeve.

[0007] Preferably, the rotating connection assembly includes a first connecting arm and a second connecting arm. The first connecting arm is provided with a socket, and the second connecting arm is provided with a post, which cooperates with the socket.

[0008] Preferably, the upper part of the socket is provided with a trumpet-shaped guide surface.

[0009] Preferably, the bottom of the insert has a tapered mating surface that is adapted to the flared guide surface.

[0010] Preferably, the top of the shell structure is detachably provided with an adjustment ring, which includes a first arc ring and a second arc ring. The adjustment ring is used to change the diameter of the opening at the top of the shell structure.

[0011] Preferably, magnets are provided at the bottom of the first and second arc-shaped rings.

[0012] Preferably, the first arc ring is connected to the first sleeve by bolts, and the second arc ring is connected to the second sleeve by bolts.

[0013] Preferably, the inner diameter of the shell structure gradually decreases from bottom to top.

[0014] The present invention can achieve the following beneficial effects:

[0015] 1. This utility model, through a shell structure composed of a first and second jacket, combined with a first and second gripping rod, changes the traditional method of manually applying fireproof putty. Operators can easily control the jackets by holding the gripping rods, quickly filling and shaping the fireproof putty into the wire holes, significantly saving time compared to manual operation. Simultaneously, the rotating connection component adopts a detachable connection method with a plug-in and plug-in hole, making installation simple and quick, requiring no additional tools, and allowing for flexible assembly within the confined space of the distribution cabinet, effectively improving installation efficiency.

[0016] 2. The design of the inner diameter of the shell structure gradually decreasing from bottom to top can exert a squeezing effect on it when filling the fireproof putty, so that the fireproof putty adheres more tightly to the wire hole and the cable surface, effectively expelling internal air, reducing air bubbles and gaps, improving the density of the fireproof putty, and reducing the risk of cracking; the flared guide surface of the insertion hole matches the conical mating surface of the insertion post, ensuring a stable jacket connection, reducing shaking and gaps at the connection point, ensuring tool stability during installation, thereby ensuring the quality of fireproof putty installation and improving fireproof and sealing performance.

[0017] 3. The detachable top adjustment ring consists of a first arc ring and a second arc ring. By installing, disassembling, and adjusting the combination, the opening diameter of the top of the housing structure can be changed to accommodate different sizes of wire holes and changes in the number of cables in the distribution cabinet or lighting power supply box. At the same time, the adjustment ring provides two fixing methods: magnetic adsorption and bolt connection. It can meet the needs of rapid installation and ensure stability in complex working conditions, making the tool suitable for diverse installation scenarios and expanding its application range.

Detailed Implementation

[0026] Example 1:

[0027] This tool is used inside a lighting power supply box, which contains a two-phase circuit breaker, a single-phase fuse, an AC contactor, and 2x2.5mm² cables. Its circuit diagram is shown in Figure 5. The cables in this lighting power supply box are threaded through wire holes at the bottom of the box. Fireproof putty is installed between the cables and the wire holes. On the one hand, the fireproof putty effectively blocks flames and high temperatures, preventing fire from spreading to other areas through gaps in the box or cable holes; on the other hand, it seals the wire holes in the lighting power supply box. The conventional method of installing fireproof putty is for workers to manually pile it into the wire holes. This operation is time-consuming, and the piled-up shape is irregular. Furthermore, the fireproof putty piled by hand is not dense enough and is prone to cracking.

[0028] Preferred solutions include Figs. 1 to 4 As shown, a fireproof putty installation tool for a power distribution cabinet includes a first sleeve 1 and a second sleeve 2. The first sleeve 1 and the second sleeve 2 are detachably connected by a rotating connecting assembly 3. The first sleeve 1 and the second sleeve 2 are mirror images of each other, forming a shell structure with openings at the bottom and top. A first handle 4 is connected to the first sleeve 1, and a second handle 5 is connected to the second sleeve 2.

[0029] The two sleeves are detachably connected via a rotating connecting assembly. This allows them to fit into the limited space of the distribution cabinet and enables flexible assembly and disassembly to suit different usage scenarios and needs, facilitating portability and storage. The shell structure, with openings at both the bottom and top, is specifically designed for fire-retardant putty installation. The bottom opening allows it to fit over the wire hole, confining the fire-retardant inside the shell; the top opening facilitates the filling and shaping of the fire-retardant. The first and second grips provide operators with excellent gripping points, allowing for easier and more stable control of the sleeves and adjustment of the fire-retardant's position and shape. Compared to traditional manual operation, this significantly improves the convenience and efficiency of installation.

[0030] Furthermore, the rotating connection assembly 3 includes a first connecting arm 301 and a second connecting arm 302. The first connecting arm 301 is provided with a socket 303, and the second connecting arm 302 is provided with a post 304, which cooperates with the socket 303.

[0031] In practice, when connecting the first and second jackets, simply align the pin on the second connecting arm with the socket on the first connecting arm and insert it. The operation is simple and quick, requiring no additional tools. This connection method ensures a secure connection between the two jackets, preventing them from easily separating when using installation tools to work with the fireproof putty, thus ensuring smooth installation. Simultaneously, the fit between the pin and the socket allows the jackets to rotate to a certain extent, facilitating adjustments by the operator based on the actual position and angle of the wire hole for optimal installation results.

[0032] Furthermore, the upper part of the socket 303 is provided with a trumpet-shaped guide surface 303.1.

[0033] The design of the 303 socket greatly reduces the difficulty of aligning the plug and the socket, and improves the efficiency and success rate of the connection.

[0034] Furthermore, the bottom of the insert 304 is provided with a tapered mating surface 304.1, which is adapted to the flared guide surface 303.1.

[0035] When the insert is inserted into the socket, the tapered mating surface fits tightly against the flared guide surface, forming a good sealing and positioning effect, making the connection between the first and second jackets more stable and reducing the shaking and gaps at the connection point.

[0036] Furthermore, the top of the shell structure is detachably provided with an adjustment ring 6, which includes a first arc ring 601 and a second arc ring 602. The adjustment ring 6 is used to change the diameter of the opening at the top of the shell structure.

[0037] In actual distribution cabinets or lighting power boxes, the size of the wire holes and the number of cables vary. The existence of the adjusting ring allows the installation tool to adapt to different sizes of wire holes and cable arrangements. By installing or removing the adjusting ring, and adjusting the combination of the first and second arc rings, the diameter of the opening at the top of the housing structure can be changed. The fixing methods of the first arc ring 601 and the second arc ring 602 include at least the following two:

[0038] The first type has magnets at the bottom of the first arc ring 601 and the second arc ring 602. When installing the adjustment ring, simply bring the first and second arc rings with magnets close to the top of the housing structure, and the magnets will automatically adhere to the housing, eliminating the need for cumbersome fixing operations using bolts or other tools.

[0039] In the second method, the first arc-shaped ring 601 is connected to the first clamping sleeve 1 by bolts, and the second arc-shaped ring 602 is connected to the second clamping sleeve 2 by bolts. Besides the auxiliary fixing method using magnets, using bolts to connect the first and second arc-shaped rings to the first and second clamping sleeves provides a more secure and reliable fixing method for the adjusting ring.

[0040] Furthermore, the inner diameter of the shell structure gradually decreases from bottom to top. This is used to extrude the fireproof putty into a conical shape.

[0041] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
