Detailed Implementation

[0019] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0022] Example 1 The equipment maintenance device provided in this application can be used to maintain and repair the transparent paper conveying assembly of cigarette packaging equipment to ensure normal production operation.

[0023] See Figures 1 to 5 As shown, the equipment maintenance device provided in this application includes a positioning mechanism and a rotary wrench 101. The positioning mechanism includes a positioning element 102, which is detachably connected to the equipment. The rotary wrench 101 includes a gripping rod 103, a connecting rod 104, and a guide assembly. The connecting rod 104 is detachably connected to the part to be inspected on the equipment to allow the part to be inspected to rotate. The positioning element 102 is sleeved on the connecting rod 104, and the connecting rod 104 can rotate relative to the positioning element 102. One end of the gripping rod 103 is movably connected to the connecting rod 104, and the guide assembly is installed between the gripping rod 103 and the connecting rod 104 so that the other end of the gripping rod 103 can swing unidirectionally relative to the connecting rod 104.

[0024] Specifically, before the operator can rotate and lock the part under inspection, the positioning element 102 can be connected to the equipment. Since the positioning element 102 is sleeved on the connecting rod 104, it can provide stable support and axial positioning for the connecting rod 104, reducing slippage or displacement during operation. The connecting rod 104 is used for detachable connection with the part under inspection to rotate and lock the part under inspection. The connecting rod 104 can rotate relative to the positioning element 102 so that the setting of the positioning element 102 does not affect the locking function of the rotary wrench 101.

[0025] When the operator locks the part under inspection by rotation, the gripping rod 103 can only swing in one direction relative to the connecting rod 104. In the opposite direction, the gripping rod 103 and the connecting rod 104 are fixed to each other. For ease of understanding, the gripping rod 103 is designed to swing only clockwise relative to the connecting rod 104. When the gripping rod 103 swings counterclockwise, the gripping rod 103 and the connecting rod 104 are fixedly connected, causing the connecting rod 104 to rotate, thereby locking the part under inspection by rotation. Within a certain spatial range, when the gripping rod 103 drives the connecting rod 104 to rotate counterclockwise to a certain angle, making it difficult for the operator to operate, there is no need to separate the workpiece from the part under inspection to change the angle. The gripping rod 103 can be rotated clockwise relative to the connecting rod 104 to adjust the angle position of the gripping rod 103, thus allowing the part under inspection to continue to rotate. The operator can complete the continuous rotation of the part under inspection without frequently adjusting the angle, which can improve maintenance efficiency.

[0026] The equipment maintenance device provided in this application can reliably connect to the equipment during equipment maintenance, improving operational stability, reducing operational difficulty, and increasing the efficiency of equipment maintenance, thereby improving the production efficiency of the equipment.

[0027] In an optional embodiment, the positioning component 102 includes a positioning block 105 and a limiting block 106; the limiting block 106 is connected to the positioning block 105; the device is provided with a limiting hole, and the limiting block 106 is inserted into the limiting hole; the positioning block 105 has a positioning hole 107, the positioning hole 107 is opposite to the position of the part to be inspected, and the connecting rod 104 passes through the positioning hole 107 to connect with the part to be inspected.

[0028] In this embodiment, such as Figure 1 and Figure 2As shown, the limiting block 106 has a cubic structure and can be inserted into a matching square limiting hole to fix the relative position of the positioning member 102 and the equipment. The connecting rod 104 is located in the positioning hole 107 of the positioning block 105, which can support and position the rotating wrench 101. The cubic structure of the limiting block 106 ensures that the positioning member 102 will not move with the rotating wrench 101. Furthermore, the positioning hole 107 is positioned opposite to the part to be inspected, which ensures that the connecting rod 104 is directly and accurately positioned and connected to the part to be inspected, reducing the difficulty of operation and simplifying the operation steps.

[0029] In an optional embodiment, the positioning mechanism further includes a first magnetic suction member 108; the positioning member 102 is provided with a first mounting cavity, and the first magnetic suction member 108 is installed in the first mounting cavity to magnetically connect with the device.

[0030] In this embodiment, specifically, a mounting groove is provided in the middle of the positioning member 102, and the first magnetic member 108 is installed in the mounting groove to magnetically connect with the device, further improving the fixing effect of the positioning member 102. The magnetic connection method allows the positioning member 102 to be quickly fixed to the device without the need for screws or other fasteners, greatly simplifying the installation process. Furthermore, the positioning member 102 can be easily removed from the device, improving operational flexibility and efficiency.

[0031] In an optional embodiment, the connecting rod 104 includes a rod body 109 and at least one connecting part 110; one end of the rod body 109 is connected to the gripping rod 103; any connecting part 110 is detachably connected to the other end of the rod body 109 so that the connecting part 110 is adapted to the drive structure of the part to be inspected.

[0032] In this embodiment, the present application can select a suitable connecting part 110 to connect with the rod body 109 according to the specific driving structure and specifications of the part to be inspected. For example, when the part to be inspected is an internal hexagonal bolt, a connecting part 110 with a hexagonal prism can be inserted into the groove of the internal hexagonal bolt to achieve rotational locking of the internal hexagonal bolt; when the part to be inspected is an external hexagonal bolt, a connecting part 110 with a hexagonal groove can be selected, and the external hexagonal bolt can be inserted into the hexagonal groove to achieve rotational locking of the external hexagonal bolt. In addition, the corresponding connecting part 110 can also be selected according to the specifications of the part to be inspected. This design greatly improves the compatibility of the device with different parts and reduces the need to prepare multiple special tools due to changing the object to be inspected.

[0033] Optionally, such as Figure 3 As shown, the rod body 109 and the connecting part 110 are threaded together.

[0034] In an optional embodiment, the connecting rod 104 further includes a second magnetic member 111; the connecting part 110 is provided with a second mounting cavity, and the second magnetic member 111 is installed in the second mounting cavity to magnetically connect with the part to be inspected.

[0035] In this embodiment, specifically, the connecting part 110 is provided with a mounting groove, and the mounting groove is located at the end of the connecting part 110 connected to the rod body 109. The second magnetic suction member 111 is installed in the mounting groove, which can hide the second magnetic suction member 111. When the connecting part 110 is docked with the part to be inspected, the connecting part 110 can be magnetically connected to the part to be inspected, ensuring a more accurate relative position between the connecting part 110 and the part to be inspected. The magnetic connection method allows the connecting part 110 to be quickly fixed to the part to be inspected, and the connecting part 110 can also be easily removed from the part to be inspected, improving the flexibility and efficiency of operation.

[0036] Example 2 The equipment maintenance device in this second embodiment is an improvement based on the above embodiments. The technical content disclosed in the above embodiments will not be described again, and the content disclosed in the above embodiments also belongs to the content disclosed in this second embodiment.

[0037] See Figure 4 and Figure 5 As shown, in an optional embodiment, the guide assembly includes a ratchet 112, a pawl 113, and an elastic element 114; the ratchet 112 is connected to the connecting rod 104; one end of the pawl 113 is connected to the gripping rod 103, and the other end of the pawl 113 is engaged with the ratchet 112; the elastic element 114 is installed between the pawl 113 and the gripping rod 103 so that the pawl 113 has a tendency to engage with the tooth groove of the ratchet 112.

[0038] In this embodiment, the cooperation of the ratchet 112, pawl 113, and spring ensures that the gripping lever 103 can only move in one direction relative to the connecting lever 104. Figure 4 The lever 103 can be swung in the direction A shown in the diagram, thereby adjusting the angular position of the grip lever 103 relative to the connecting lever 104 for easier operation by the operator. Figure 4 As shown, the ratchet 112 connected to the connecting rod 104 remains stationary. When the gripping rod 103 swings clockwise, the pawl 113 slides sequentially across the teeth of the ratchet 112, thereby adjusting the angle of the gripping rod 103. When the gripping rod 103 needs to swing in the opposite direction, the pawl 113 connected to the gripping rod 103 will continuously engage with the teeth of the ratchet 112 under the action of the spring. When the part to be inspected is rotated and locked, it can be ensured that the gripping rod 103 and the connecting rod 104 rotate synchronously. Moreover, the meshing mechanism of the ratchet 112 and the pawl 113 can achieve precise positioning tooth by tooth, ensuring that the gripping rod 103 can stably stop at each tooth position, improving the accuracy and reliability of the operation.

[0039] Alternatively, the guide assembly can also be configured as a wedge-type one-way locking structure, which can also enable the gripping rod 103 to swing in one direction relative to the connecting rod 104. However, its structure is more complex than that of a ratchet mechanism, and its production cost is higher.

[0040] In an optional embodiment, the equipment maintenance device further includes a connector 115; the end of the connecting rod 104 is provided with a connecting protrusion 116, and the ratchet 112 is sleeved on the connecting protrusion 116; the connecting protrusion 116 is provided with a connecting hole 117; the connector 115 passes through one end of the gripping rod 103 to connect with the connecting hole 117; and the other end of the gripping rod 103 can rotate relative to the connector 115.

[0041] In this embodiment, such as Figure 5 As shown, the connecting protrusion 116 is provided with a key, and the ratchet 112 is provided with a corresponding keyway. The ratchet 112 is sleeved on the connecting protrusion 116 so that the key and the keyway cooperate, thereby reliably fixing the ratchet 112 to the end of the connecting rod 104. A threaded hole is provided in the middle of the connecting protrusion 116. The gripping rod 103 is connected to the threaded hole by a bolt, but the bolt does not lock the gripping rod 103 to the connecting rod 104, so that the gripping rod 103 can swing relative to the connecting rod 104, thereby adjusting the angle position of the gripping rod 103.

[0042] In an optional embodiment, the end of the gripping rod 103 is provided with a first receiving cavity and a second receiving cavity; the first receiving cavity is provided with an opening, and the connecting protrusion 116 and the ratchet 112 are placed in the first receiving cavity through the opening; an movable gap is provided between the ratchet 112 and the first receiving cavity; the second receiving cavity is connected to the first receiving cavity; the pawl 113 and the elastic member 114 are located in the second receiving cavity; the second receiving cavity forms a reserved space, and the pawl 113 can bounce within the reserved space.

[0043] In this embodiment, the ratchet 112, pawl 113, and elastic element 114 are integrated into the first and second receiving cavities, providing support and fixation for the aforementioned components. This internal integration design results in a cleaner appearance and improves the product's aesthetics. Furthermore, the receiving cavity design provides physical protection for the components, reducing the impact of the external environment and extending their service life.

[0044] Specifically, such as Figure 5As shown, the grip lever 103 includes a handle 118 and a cover plate 119. The handle 118 has a receiving hole 120. The handle 118 is plate-shaped, and the receiving hole 120 is a circular hole that penetrates both sides of the handle 118. The end face of the connecting rod 104 is circular, and the diameter of the end face of the connecting rod 104 is larger than the diameter of the receiving hole 120. On the plate facing the connecting rod 104, the edge of the receiving hole 120 fits against the end face of the connecting rod 104, allowing the end face of the connecting rod 104 to position the handle 118 and enabling the ratchet 112 to be placed within the receiving hole 120.

[0045] In addition, the handle 118 is provided with a receiving groove 121, which is located on the side of the handle 118 opposite to the connecting rod 104. The pawl 113 and the elastic element 114 are located in the receiving groove 121. Specifically, a pin 122 is provided at the bottom of the receiving groove 121, and the pawl 113 is mounted on the pin 122 and can rotate relative to the handle 118. A recess 123 is provided on the wall of the receiving groove 121, and a spring is installed between the pawl 113 and the recess 123. The cover plate 119 is connected to the side of the handle 118 opposite to the connecting rod 104. The cover plate 119 is provided with a slightly larger through hole, and the connector 115 passes through the through hole to connect the handle 118 to the connecting rod 104, and the handle 118 can rotate relative to the connector 115. The cover plate 119 and the receiving hole 120 form a first receiving cavity, and the cover plate 119 and the receiving groove 121 form a second receiving cavity. This allows the guide assembly to be integrated and enclosed between the handle 118 and the cover plate 119, making the overall device more compact. The cover plate 119 also facilitates the assembly and disassembly of the guide assembly.

[0046] In an optional embodiment, the handle 118 has a notch 124 on the side opposite to the connecting rod 104, and the cover plate 119 is embedded in the notch 124. The embedded design of the cover plate 119 makes it flush with the surface of the handle 118, resulting in a cleaner and more aesthetically pleasing appearance. Furthermore, the notch 124 can limit the position of the cover plate 119, increasing the reliability of the connection.
