[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A connecting rod and a positioning block are connected to the counterweight ring, and a T-shaped handle is provided on the positioning block. Multiple positioning rods are installed on the counterweight ring at equal intervals outside the connecting rod.

[0009] Furthermore, a preferred structure is that the positioning block has a square cross-section, and the cross-sectional area of ​​the positioning block is larger than the cross-sectional area of ​​the connecting rod.

[0010] In addition, a preferred structure is that the insertion rod assembly includes a handle block, a plurality of limiting insertion rods are installed at equal intervals on the bottom of the handle block, and an insertion hole is opened in the movable baffle at the limiting insertion rod, and a slot for inserting the insertion rod assembly is opened on the fixed base two.

[0011] In addition, a preferred structure is that an extension plate is installed on one side of the T-shaped handle, and a magnetic sealing plug is provided on one side of the extension plate at the corresponding slot.

[0012] In addition, a preferred structure is that the movable baffle has a through hole at the positioning block, and the end face of the movable baffle is provided with a magnetic layer with the opposite polarity to the magnetic sealing plug, and the bottom of the movable baffle has a positioning groove at the positioning rod.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-6 A coupler component with a protective mechanism includes a coupler component body 1, which includes a pusher. An anti-jump component 2 is provided on the coupler component body 1 and located at the pusher. The anti-jump component 2 includes a first fixed seat 21 and a second fixed seat 22. The first fixed seat 21 and the second fixed seat 22 are respectively located on both sides above the pusher. A movable limiting plate 23 is rotatably mounted on the first fixed seat 21. An avoidance groove is provided at the other end of the movable limiting plate 23 and located at the second fixed seat 22. A movable insert rod 24 that can pass through the second fixed seat 22 is slidably provided inside the movable limiting plate 23 on the side near the second fixed seat 22. The movable insert rod 24 and the second fixed seat 22 are connected and limited by an insert rod assembly 25.

[0025] Meanwhile, a movable part 26 is slidably disposed inside the fixed base 22, and a movable baffle 27 for limiting the insertion rod assembly 25 is movably sleeved outside the movable part 26. A movable cavity is opened inside the fixed base 22 at the movable baffle 27.

[0026] The movable component 26 includes a counterweight ring 263, which is slidably disposed within the fixed base 22. A connecting rod 262 and a positioning block 261 are connected to the counterweight ring 263. A T-shaped handle is provided on the positioning block 261. Multiple positioning rods 264 are installed at equal intervals on the counterweight ring 263 outside the connecting rod 262.

[0027] Furthermore, the positioning block 261 has a square cross-section, and the cross-sectional area of ​​the positioning block 261 is larger than the cross-sectional area of ​​the connecting rod 262.

[0028] Meanwhile, the insertion rod assembly 25 includes a handle block, with multiple limiting insertion rods installed at equal intervals at the bottom of the handle block, and insertion holes are opened in the movable baffle 27 at the limiting insertion rods, and slots for insertion of the insertion rod assembly 25 are opened on the fixed base 22.

[0029] Furthermore, an extension plate is installed on one side of the T-shaped handle, and a magnetic sealing plug 265 is provided on one side of the extension plate at the corresponding slot.

[0030] Furthermore, a through hole is provided inside the movable baffle 27 at the positioning block 261, and a magnetic layer with the opposite polarity to the magnetic sealing plug 265 is provided on the end face of the movable baffle 27, and a positioning groove is provided at the bottom of the movable baffle 27 at the positioning rod.

[0031] Furthermore, an auxiliary insertion hole is provided inside the movable insertion rod 24 at the limit insertion rod.

[0032] The specific structure, connection method and working principle of the above-mentioned coupler component body 1 are all existing technologies that are currently publicly available on the market, so they will not be described in detail.

[0033] In this embodiment, the movable limiting plate 23 is rotated to be above the push iron, and its movable insertion rod 24 is aligned with the fixed base 22 for insertion. When the movable limiting plate 23 rotates, it is necessary to ensure that one end of its movable insertion rod 24 is away from its fixed base 22.

[0034] After the movable plug rod 24 is inserted, the plug rod assembly 25 is inserted to limit the movable plug rod 24 and the fixed seat 22. Then, holding the T-shaped handle, the movable part 26 is moved away from the fixed seat 22, and the positioning block 261 of the movable part 26 is moved away from the fixed seat 22 until it can no longer move. At this time, its counterweight ring 263 is in contact with the movable baffle 27, and its positioning plug rod is inserted into the positioning groove of the movable baffle 27. Then the movable part is rotated until its magnetic sealing plug 265 is aligned with its slot. At this time, its movable baffle 27 limits the plug rod assembly 25, and the movable part 26 is moved towards the fixed seat 22 until its magnetic sealing plug 265 is magnetically connected to the movable baffle 27. Thus, the anti-jump component 2 limits the push iron, preventing the push iron from moving upward and preventing the coupler component body 1 from disengaging.

[0035] When the anti-jump component 2 is not needed, move the movable part 26 away from the fixed base 22 until it can no longer move. At this time, its counterweight ring 263 is in contact with the movable baffle 27, and its positioning rod is inserted into the positioning groove of the movable baffle 27. Then rotate the movable part until its magnetic sealing plug 265 is away from its slot. Take out the rod assembly and move one end of the movable rod 24 away from its fixed base 22. Then the movable limit plate 23 can be rotated until it is away from the push iron, so as not to hinder the normal use of the push iron, nor to hinder the normal use of the coupler component body 1.

[0036] In this utility model, by providing an anti-jump component 2 on the coupler components, the pusher can be prevented from jumping up accidentally, and the coupler components can be prevented from detaching. Moreover, the anti-jump component 2 is easy to operate.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
