[0019] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0020] In this disclosure, unless otherwise stated, directional words such as "up, down, left, right, front, back" are used based on the Figure 1The XYZ coordinate system in the figure is defined. Specifically, the X direction refers to the front-to-back direction, the Y direction refers to the left-to-right direction, and the Z direction refers to the up-down direction. "Inside" and "outside" refer to the inside and outside of each component's own outline. The terms "first" and "second" are used to distinguish one element from another and do not have a sequential or significant meaning. In addition, when referring to the figures below, the same reference numerals in different figures represent the same or similar elements, which are not repeated in this disclosure.

[0021] According to some embodiments of the present disclosure, there is provided an external locking lubricating oil injection device, referring to Figure 1 and Figure 2 As shown in the figure, the external locking lubricating oil filling device includes an oil storage pot 1, a protective cover 2 and a mounting bracket 3. The oil storage pot 1 is arranged on the upper part of the protective cover 2 and has an oil filling nozzle 4 extending into the protective cover 2. The mounting bracket 3 is connected to the protective cover 2 and is located at the rear side of the oil filling nozzle 4. The protective cover 2 has a first baffle 21 located in front of the oil filling nozzle 4. The projection of the oil filling nozzle 4 in the up and down directions falls into the projection of the first baffle 21 in the up and down directions.

[0022] Through the above technical solution, in the external locking lubricating oil filling device provided by the present invention, the first baffle 21 in the protective cover 2 can provide protection for the oil filling nozzle 4 from the front side of the oil filling nozzle 4, preventing external rainwater and dust from contacting the oil filling nozzle 4 from the front side of the oil filling nozzle 4, thereby solving the technical problem that the oil filling nozzle 4 is easily exposed to rainwater and dust.

[0023] It should be noted that the mounting bracket 3 can be connected to the locking frame of the external lock, and the present disclosure does not limit this.

[0024] In some embodiments of the present disclosure, reference Figure 1 and Figure 2 As shown in FIG, the protective cover 2 can have two second baffles 22 spaced apart in the left-right direction. The two second baffles 22 are connected to the left and right sides of the first baffle 21, and the vertical projection of the oiling nozzle 4 falls into the vertical projection of the second baffles 22. In this way, the two second baffles 22 can provide protection for the oiling nozzle 4 from both sides, preventing rainwater and dust from reaching the oiling nozzle 4 from the left and right sides. This further solves the technical problem of the oiling nozzle 4 being easily exposed to rainwater and dust, and achieves windproof, dustproof, and sandproof protection for the oiling nozzle 4.

[0025] In some embodiments of the present disclosure, reference Figure 1 and Figure 2As shown in , the mounting bracket 3 can be rotatably connected to the protective cover 2 around a rotation axis extending in the left-right direction. A connecting structure 5 can be provided between the mounting bracket 3 and the first baffle 21, and the mounting bracket 3 is detachably connected to the first baffle 21 via the connecting structure 5. Here, the rotatable connection between the mounting bracket 3 and the protective cover 2 can facilitate the cleaning of the oiling nozzle 4 in the protective cover 2, wherein the provision of the connecting structure 5 can detachably connect the first baffle 21 and the mounting bracket 3. When the two are connected together, the stability of the externally locked lubricating oiling device can be improved.

[0026] In some embodiments of the present disclosure, reference Figure 1 As shown in , the mounting frame 3 may be provided with a connecting post 51 extending in the front-to-back direction. The front end of the connecting post 51 is inserted through the first baffle 21 and has an external thread. The connecting structure 5 includes a nut 52 threadedly connected to the front end. In this way, the threaded connection between the thread and the front end can achieve a detachable connection between the mounting frame 3 and the first baffle 21, which is simple in structure and easy to operate.

[0027] In some embodiments, reference Figure 1 As shown in FIG, the first baffle 21 may be provided with a downwardly opening mating slot 211 for the front end to be inserted into the first baffle 21. The mating slot 211 has a width in the left-right direction, and the width of the mating slot 211 gradually decreases from bottom to top. This facilitates inserting the connecting column 51 into the mating slot 211 from bottom to top.

[0028] In some embodiments, reference Figure 1 As shown in , the front end is also provided with a matching hole positioned at the front side of the external thread, and a stop pin 53 is provided in the matching hole. Like this, the stop pin 53 can also prevent the nut 52 from being accidentally loosened.

[0029] In some embodiments, reference Figure 1 As shown in , the left and right sides of the mounting frame 3 can be respectively provided with connecting columns 51. In this way, the stability of the mounting frame 3 after being connected to the first baffle 21 can be improved.

[0030] In some embodiments, the connecting post 51 may be fixedly connected to the mounting bracket 3. This may improve the connection strength between the two.

[0031] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments.
