Description

Technical Field

[0001] The utility model relates to the technical field of maintenance auxiliary tools, in particular to a maintenance device for preventing screws from falling off. Background Art

[0002] With the development of industrial intelligence, the level of automation of production lines in cigarette factories is also increasing. In order to ensure production efficiency, the equipment inspection and maintenance cycle is short, especially the maintenance of circuit control cabinets is more frequent. For example, when conducting secondary wiring of current and voltage transformers or integrated automatic devices, in some cases, the space where the threaded holes are located is small, and the installation and removal of screws often need to be completed with one hand, and the screws are easy to fall off. In order to solve this problem, magnetic screwdrivers are currently widely used to use magnets to absorb the screws to complete installation and removal. However, when actually tightening the screws, the screws often fall off the screwdriver due to shaking of the hands or improper force. Sometimes the fallen screws are difficult to find and collect, posing a safety hazard to the normal operation of the equipment. Utility Model Content

[0003] In view of this, the purpose of the utility model is to provide a maintenance device for preventing screws from falling off, so as to solve the problem in the prior art that fallen screws are difficult to collect during the maintenance of circuit and electric control cabinets.

[0005] Optionally, the anti-drop net structure is connected to the connecting piece by an elastic rope, and the elastic rope can be used to adjust the spacing between adjacent anti-drop net components so that obstacles can pass through.

[0006] Optionally, a plurality of long slots are provided along the side of the anti-drop net structure away from the insulating tube, and one end of the elastic rope passes through the long slot and is connected to the other end, and both are connected to the connecting piece, so that the connecting piece can be freely moved along the long slot by the elastic rope. By sliding the elastic rope in the long slot, the spacing of the connecting piece can be adjusted to facilitate the passage of obstacles.

[0007] Optionally, telescopic extension rods are provided at both ends of the insulating tube, one end of which is slidably connected in the insulating tube, and the other end is hinged to the support. The regional position of the entire protective net assembly can be adjusted by the telescopic extension rod, and at the same time, the applicability of the device to electric control cabinets of different specifications is also improved.

[0008] Optionally, the support is a magnetic base. Using the magnetic base for adsorption installation is convenient and quick.

[0009] Optionally, the anti-dropping net structure is made of insulating material. Insulating material is used to prevent electrostatic hazards.

[0010] Optionally, a plurality of limit blocks are provided axially on one side of the insulating tube. By surrounding the anti-drop net structure on the insulating tube, the mesh of the anti-drop net structure is clamped on the limit blocks during the surrounding process, so as to prevent the anti-drop net structure from being entangled, and facilitate the storage and portability of the device.

[0011] Optionally, a plurality of micro permanent magnets are provided on the anti-drop net structure. The micro permanent magnets are provided so that some areas of the anti-drop net structure have a certain magnetic adsorption force, so that among the dropped screws, part of the screw thread segments are stuck in the mesh holes, and part of the screws are adsorbed by the micro permanent magnets. When the device is removed after maintenance, the remaining movable screws on the anti-drop net structure are adsorbed by the micro permanent magnets or the thread segments are stuck in the mesh holes and cannot fall, thereby achieving the purpose of preventing the screws from falling and collecting them.

[0018] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can understand the advantages and effects of the present invention from the contents disclosed in this specification. It should be noted that the illustrations provided in the following embodiments are only for exemplary descriptions, and they are only schematic diagrams, not physical diagrams, and cannot be understood as limitations on the present invention.

Therefore, the terms describing the positional relationship in the figures are only used for illustrative purposes and cannot be understood as limitations on the present invention. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0020] like Figure 1-Figure 3 As shown in FIG. 1 , a screw anti-dropping maintenance device of the utility model is provided, comprising at least two anti-dropping net components installed in parallel, such as Figure 1 As shown, in the present embodiment, there are three anti-drop net components installed in parallel, including two anti-drop net components with anti-drop net structures 3 set on one side, and one anti-drop net component with two anti-drop net structures 3 set on the opposite side, which are connected in sequence. Specifically, the anti-drop net component includes an insulating tube 1, and both ends of the insulating tube 1 are connected with a support 2 for detachable connection with the electric control cabinet body, and one side or the opposite side of the insulating tube 1 is connected with an anti-drop net structure 3. The anti-drop net structure 3 is made of insulating flexible material, and the size of its mesh is determined according to actual use. For example, the most commonly used screw size for electricians is M4, and the nut size is about 7.22mm, so the permeable size of the mesh can be set to 7mm. In order to better absorb the fallen screws, several micro permanent magnets can be glued to the anti-drop net structure 3, so that some areas of the anti-drop net structure 3 have a certain magnetic adsorption force, so that among the fallen screws, part of the screw thread segments are stuck in the mesh holes, and part of the screws are absorbed by the micro permanent magnets. When the maintenance is completed and the device of the utility model is removed, the remaining movable screws on the anti-drop net structure 3 are absorbed by the micro permanent magnets or the thread segments are stuck in the mesh holes and cannot fall.

[0021] like Figure 1As shown, in this embodiment, six connectors 4 are provided on the side of the anti-drop net structure 3 away from the insulating tube 1, and adjacent anti-drop net components are connected by corresponding connectors 4. Specifically, the anti-drop net structure 3 and the connector 4 are connected by elastic ropes 41, and three long slots 31 are provided along the side direction of the anti-drop net structure 3 away from the insulating tube 1. One end of the elastic rope 41 passes through the long slot 31 and is connected to the other end, and is connected to the connector 4 together, so that the connector 4 can move freely along the long slot 31 through the elastic rope 41, and there are two connectors 4 in each long slot 31 that slide freely. Since cables, busbars, etc. will pass through the middle of some electric control cabinets, the anti-drop net structure 3 cannot be designed as a whole, and needs to be assembled in blocks. According to actual conditions, the spacing of the connectors 4 is controlled by the sliding of the elastic rope 41, and the elastic rope 41 itself can be extended and retracted in the length direction to allow different obstacles to pass through, and then connected by snap fasteners.

[0022] like Figure 2 As shown, in this embodiment, the connecting member 4 is a sub-buckle 42 or a female buckle 43. When the connecting member 4 of one anti-net-dropping component is a sub-buckle, the connecting member 4 of the adjacent anti-net-dropping component is a female buckle 43, and the corresponding settings are sufficient.

[0023] like Figure 3 As shown, in the present embodiment, the support 2 is a magnetic seat, which is convenient for being directly adsorbed on the inner wall of the electric control cabinet body to complete the fixation of the insulating tube 1; telescopic extension rods are also provided at both ends of the insulating tube 1, one end of the telescopic extension rod is slidably connected in the insulating tube 1, and the other end is hinged to the support 2. The telescopic extension rod is provided to adapt to electric control cabinets of different sizes. Since the support 2 and the insulating tube 1 are rotatably hinged through the pin shaft, the installation direction of the support 2 can be adjusted according to actual conditions to adapt to the use scenarios of more equipment.

[0024] To facilitate the storage and portability of the device, two limit blocks 11 are axially provided on one side of the insulating tube 1. When storing, the anti-drop net structure 3 can be wrapped around the insulating tube 1, and the mesh of the anti-drop net structure 3 can be stuck on the limit blocks 11 when wrapping, so as to prevent the anti-drop net structure from being entangled.

[0025] The working principle of the utility model is as follows:

[0026] Before maintenance of the electric control cabinet, the overall length of the insulating tube 1 is adjusted by the telescopic extension rod according to the size of the electric control cabinet and the passage of cables, busbars, etc. inside the electric control cabinet, and the adjacent anti-drop net components are connected by the male and female buckles. The spacing of the connector 4 is controlled by sliding the elastic rope 41, and the elastic rope 41 itself can be extended and retracted in the length direction to allow different obstacles (cables, busbars, etc.) to pass. Finally, the support 2 is installed correspondingly below the working area in the electric control cabinet.

[0027] The above embodiments are only used to illustrate the technical solution of the utility model and are not intended to limit it. Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
