[0002] An electric control cabinet is a control cabinet (box) that assembles switchgear, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements. Its layout should meet the requirements for the normal operation of the power system, be convenient for maintenance, and not endanger the safety of personnel and surrounding equipment.

[0003] For example, a Chinese patent with the authorization announcement number CN 212626634 U discloses a new cabinet door for an electric control cabinet, including a cabinet door body and a connecting device for connecting the cabinet door body to the cabinet body of the electric control cabinet; the connecting device includes a first connecting rod and a second connecting rod. One end of the first connecting rod is hinged to a fixed ear provided on the inner wall of one side of the cabinet body of the electric control cabinet through a pin shaft, and the other end is hinged to one end of the second connecting rod through a pin shaft. The other end of the second connecting rod is connected to the inner side wall of the cabinet door body through a horizontal movement structure, and the cabinet door body can move horizontally towards one side of the cabinet body of the electric control cabinet through the horizontal movement structure.

[0004] However, there are still some problems in the above patent.

[0073] In a further embodiment, when the lock core has been used for a long time or is in a humid environment for a long time, in order to avoid the situation that the electric cabinet door cannot be opened due to rust on the lock core, at this time, most operators inject lubricating oil into the lock core from the outside to the inside. Here, the inside refers to the inside of the lock core, and the outside refers to the outside of the lock core. By injecting lubricating oil from the outside of the lock core to the inside of the lock core, due to the small lock hole of the lock core, a large amount of lubricating oil fails to flow into the lock core, resulting in waste of lubricating oil.

[0074] To solve the above problems, the door frame gluing assembly 1 of the present device is provided with a receiving cavity and a lubrication unit 9 located in the receiving cavity; the lubrication unit 9 can inject lubricating oil into the area where the lock core is located in the triangular core lock body 20; the lubrication unit 9 includes an oiling assembly 91 provided on the door frame gluing assembly 1, an adjusting assembly 92 connected to the oiling assembly 91, an oil outlet assembly 93 connected to the adjusting assembly 92, and an oil storage tank detachably connected to the oil outlet assembly 93; an oil filling port is provided on the oil storage pipe, and a plug for sealing the oil filling port, the plug having a predetermined deformation ability, an oil injection port is provided on the triangular core lock body 20, and the oil injection port is used to connect the oil outlet end 918 of the oil outlet assembly 93 and the space where the lock core is located, so that the lubricating oil can be transported from the oil outlet assembly 93 to the lock core; through the oil outlet assembly 93, the lubricating oil can be injected from the inside of the lock core, avoiding waste of lubricating oil when injecting from the outside.

[0075] In a further embodiment, most of the existing lubricating oil adding methods are to place the lubricating oil in an injection plastic bottle, squeeze the plastic bottle to make it deform, and then let the lubricating oil flow out of the plastic bottle. By making the oil outlet position of the injection plastic bottle located in a predetermined area, the addition work of the lubricating oil is completed. However, during the squeezing process, the squeezing force is difficult to control, resulting in an excessive amount of hydraulic oil being extruded, and the lubricating oil after extrusion is difficult to collect, thus causing waste of lubricating oil.

[0076] To solve the above problems, an oiling assembly 91 is provided in this device. The oiling assembly 91 includes a mounting seat 911 connected to the door frame gluing assembly 1, a transport seat 913 provided on the mounting seat 911, a drive shaft 914 for connecting the transport seat 913 and the mounting seat 911, a first knob 912 provided at one end of the drive shaft 914, a waist-shaped transport cavity opened on the transport seat 913, a drive gear 915 sleeved on the drive shaft 914 and located in the transport cavity, a driven gear 916 meshing with the drive gear 915, and an oil inlet end 917 and an oil outlet end 918 provided on the transport seat 913; wherein two grooves are further opened on the inner wall of the transport cavity, and the two grooves are respectively communicated with the oil inlet end 917 and the oil outlet end 918. When performing the oiling work, rotate the first knob 912. The moving first knob 912 can drive the drive shaft 914 to rotate, and then the moving drive shaft 914 can drive the drive gear 915 to rotate. Furthermore, the moving drive gear 915 can drive the driven gear 916 to move in the opposite direction, and the lubricating oil can be located between the tooth grooves of the drive gear 915 and the driven gear 916. With the movement of the drive gear 915 and the driven gear 916, the lubricating oil can flow out from the oil outlet end 918. During this process, the oil output of the oil outlet end 918 is related to the rotation angle of the first knob 912. As the first knob 912 rotates, the tooth grooves on the drive gear 915 or the driven gear 916 can rotate by the same angle, and the lubricating oil is located in the tooth grooves, so that the amount of added lubricating oil can be controlled, avoiding excessive addition of lubricating oil and waste of lubricating oil.

[0077] In a further embodiment, since the addition of lubricating oil in this device is achieved by placing the lubricating oil in the gear grooves and then rotating the gears to position the lubricating oil in the gear grooves. Due to the small size of the gear grooves or the rotation speed of the gears being controlled by the first knob 912, and the first knob 912 being manually operated, it will lead to poor control of the injection flow rate. Also, during the rotation of the gears, the lubricating oil may not be able to fully fill each gear groove, resulting in difficulty in controlling the injection amount of the lubricating oil.

[0078] To solve the above problems, an adjustment assembly 92 is provided in the present device. The adjustment assembly 92 includes a connection seat 921 connected to the transport seat 913, a first channel 922, a second channel 923, and a third channel 9211 formed in the connection seat 921. One end of the third channel 9211 away from the first channel 922 extends in a direction away from the second channel 923 to form an extension tube with an external thread, a cap nut 924 screwed onto the extension tube, a second knob 925 screwed onto the top of the cap nut 924, an adjustment rod 926 provided on the second knob 925, a connecting plate 927 screwed onto the adjustment rod 926, a spring 928 connected to the connecting plate 927 and sleeved on the adjustment rod 926, a seal seat 929 connected to the other end of the spring 928, and a seal block 9210 provided on the seal seat 929. The bottom of the third channel 9211 is funnel-shaped. The first channel 922 communicates with the second channel 923 through the third channel 9211. Before adding lubricating oil, first place the seal block 9210 and the seal seat 929 in the third channel 9211, then rotate the cap nut 924 to adjust its position on the extension tube, adjust the position of the connecting plate 927 in the third channel 9211 to make the spring 928 in a compressed state, and then rotate the second knob 925. The moving second knob 925 can drive the adjustment rod 926 to move, thereby adjusting the position of the connecting plate 927 and changing the deformation of the spring 928, so as to change the pressure of the seal block 9210 on the bottom of the third channel 9211. Then when the operator rotates the first knob 912, at this time, the lubricating oil can flow into the first channel 922 from the oil outlet end 918 on the transport seat 913. As the operator continues to rotate, the lubricating oil can fill the first channel 922. Then continue to rotate the first knob 912. At this time, the oil pressure can generate a thrust on the seal block 9210, making it move away from the bottom of the third channel 9211. Further, the lubricating oil can move from the first channel 922 to the third channel 9211 and be transported along the third channel 9211 to the second channel 923, so that the lubricating oil can flow out from the oil outlet assembly 93, completing the addition of the lubricating oil. At the same time, when adding hydraulic oil through the above device, since the second channel 923 is filled with lubricating oil and then the operator continues to rotate the first knob 912, the lubricating oil can push the seal block 9210 to move, giving it a certain initial velocity. When it flows into the lock core, the lubricating oil can collide with the lock core, causing the lubricating oil to disperse into multiple oil droplets, thereby increasing the lubrication area of the lubricating oil.

[0079] In a further embodiment, while the device is refueling, first, the connecting plate 927 can be rotated to move it on the adjusting rod 926 to adjust the distance between it and the free end of the adjusting rod 926, or the cap nut 924 can be rotated to adjust the overlapping area between the cap nut 924 and the extension pipe, or the second knob 925 can be rotated to adjust the position of the adjusting rod 926 in the third channel 9211, thereby changing the area where the connecting plate 927 is located. By the above method, the deformation amount of the spring 928 is changed, and the oil pressure required for the sealing block 9210 to be away from the bottom of the third channel 9211 is adjusted, so that the lubricating oil can enter the third channel 9211 at a predetermined speed. At the same time, when there is no lubricating oil in the oil storage pipe, the position of the connecting plate 927 can be adjusted by rotating the second knob 925 at this time, thereby changing the deformation amount of the spring 928, so that there is a gap between the sealing block 9210 and the bottom of the third channel 9211, and then the lubricating oil located in the first channel 922 can be injected into the lock core.

[0080] In a further embodiment, by the above method of meshing the driving gear 915 with the driven gear 916, by blocking its oil outlet end 918, the lubricating oil can flow out at a certain speed. However, there are still some problems with this method. When the deformation amount of the spring 928 is too large, the extrusion force between the sealing block 9210 and the bottom of the third channel 9211 is too large, which can seal the lubricating oil. However, due to the excessive extrusion force, the oil pressure in the first channel 922 will be too large, which will cause damage to the gear or the sealing block 9210. When the sealing block 9210 is damaged, the lubricating oil will leak; when the deformation amount of the spring 928 is too small, there will be a gap between the sealing block 9210 and the third channel 9211, and the lubricating oil will flow out of the lock core along this gap, causing pollution of the cabinet door and waste of the lubricating oil.

[0081] To solve the above problems, an oil outlet assembly 93 is provided in this device. The oil outlet assembly 93 includes an oil outlet housing 931, a rotating shaft 933 connected to the oil outlet housing 931, a third knob 932 provided at one end of the rotating shaft 933, a locking block 934 provided at the other end of the rotating shaft 933 and located inside the oil outlet housing 931, an oil outlet nozzle 936 connected to the oil outlet housing 931, and a discharge pipe 935 provided in the oil outlet housing 931. One end of the discharge pipe 935 is located in the second channel 923, and the other end of the discharge pipe 935 is located at the oil outlet nozzle 936. The locking block 934 is of an elliptical structure. By rotating the third knob 932, the moving third knob 932 can drive the rotating shaft 933 to rotate, thereby changing the position of the locking block 934. In the non-oiling state, the long-axis region of the elliptical locking block 934 abuts against the discharge pipe 935 and deforms the discharge pipe 935, so as to clamp the discharge pipe 935 and prevent the lubricating oil from flowing out of the discharge pipe 935. Conversely, the elliptical locking block 934 does not abut against the discharge pipe 935, and the discharge pipe 935 is in a normal oil discharge state, avoiding the problem of lubricating oil leakage in the non-oiling state.

[0082] Description of working principle: The assembly of the crossbeam profile 8, column profile 10, and elbow profile 12 is completed by gluing the connecting elbow and inserting it into the avoidance cavity 56, while enabling the closed-loop docking of the protective sealing U-shaped groove 45 and the conductive shielding U-shaped groove 46. Then, the installation of the inner panel 17, the fire-retardant foam board door core 18, and the outer panel 16 is carried out, thus completing the installation of the electric control cabinet door. Then, the door frame gluing assembly 1 is placed in a special sealing device for suction and elimination of air bubbles in the glue, homogenizing the glue adhesion layer, and rapid curing of the glue. After the door frame gluing assembly 1 is completely glued and cured, machining of the required installation holes is carried out, such as the opening of the lock body fixing hole 41, the nameplate installation hole 42, and the female hole 58 for installing the wire insert 19, etc. After machining, surface painting or spraying treatment is carried out, and then the wire insert 19 is installed in the female hole 58 for installing the wire insert 19, keeping the upper end faces flush, and breaking off the remaining head at the bottom of the wire insert 19 to keep the wire insert 19 self-locking; when closing and locking the door, the triangular core of the triangular core lock body 20 is rotated 90° clockwise or counterclockwise with the triangular hollow key 21, and then the linkage mechanism drives the damping lock core and the lock tongue 25 to rotate 90° synchronously. Then, the key is rotated a certain angular displacement, while the damping lock core and the lock tongue 25 no longer follow the angular displacement but perform a linear displacement to press against the inner door frame of the cabinet until pre-tightening is in place and damping self-locking occurs. Reverse operation is carried out for decompression and unlocking; when installing the door hinge assembly 3, first, the installation between the hinge seat 29 and the hinge movable body 30 is completed by using the hinge shaft 31, and the fixing of the hinge seat 29 and the hinge movable body 30 is completed by turning the fastening screw 34 of the hinge shaft 31. Then, through the tapered countersunk screw installation hole provided on the hinge movable body 30 and the cylindrical countersunk screw installation hole located on the hinge seat 29, the glued door can be installed on the cabinet to complete the installation of the glued door; when lubricating, turning the first knob 912, the moving first knob 912 can drive the drive shaft 914 to rotate, and then the moving drive shaft 914 can drive the drive gear 915 to rotate. Furthermore, the moving drive gear 915 can drive the driven gear 916 to move in the opposite direction, and the lubricating oil can be located between the tooth grooves of the drive gear 915 and the driven gear 916. With the movement of the drive gear 915 and the driven gear 916, the lubricating oil can flow out from the oil outlet end 918. During this process, the oil output of the oil outlet end 918 and the rotation angle of the first knob 912 are related. As the first knob 912 rotates, the tooth grooves on the drive gear 915 or the driven gear 916 can rotate by the same angle, and the lubricating oil is located in the tooth grooves, so that the amount of lubricating oil added can be controlled to avoid excessive addition of lubricating oil and waste of lubricating oil;Before adding lubricating oil, first place the sealing block 9210 and the sealing seat 929 in the third channel 9211, then rotate the cover nut 924 to adjust its position on the extension pipe, adjust the position of the connecting plate 927 in the third channel 9211 to make the spring 928 in a compressed state, and then rotate the second knob 925. The moving second knob 925 can drive the adjusting rod 926 to move, thereby adjusting the position of the connecting plate 927, changing the deformation amount of the spring 928, and thus changing the pressure of the sealing block 9210 on the bottom of the third channel 9211. Then when the operator rotates the first knob 912, at this time, the lubricating oil can flow into the first channel 922 from the oil outlet end 918 on the transport seat 913. As the operator continues to rotate, the lubricating oil can fill the first channel 922. Then continue to rotate the first knob 912. At this time, the oil pressure can generate a thrust on the sealing block 9210, causing it to move away from the bottom of the third channel 9211. Furthermore, the lubricating oil can move from the first channel 922 to the third channel 9211 and be transported along the third channel 9211 to the second channel 923, so that the lubricating oil can flow out from the oil outlet assembly 93, completing the addition of the lubricating oil. At the same time, when adding hydraulic oil through the above device, since the second channel 923 is filled with lubricating oil and then the first knob 912 is continuously rotated, it will cause the lubricating oil to push the sealing block 9210 to move, giving it a certain initial velocity. When it flows into the lock core, the lubricating oil can collide with the lock core, causing the lubricating oil to be dispersed into multiple oil droplets, thereby increasing the lubrication area of the lubricating oil. When the oil outlet assembly 93 works, rotate the third knob 932. The moving third knob 932 can drive the rotating shaft 933 to rotate, thereby changing the position of the locking block 934. In the non-oil-adding state, the long-axis region of the elliptical locking block 934 abuts against the discharge pipe 935 and deforms the discharge pipe 935, thereby performing the clamping work on the discharge pipe 935 to prevent the lubricating oil from flowing out from the discharge pipe 935. On the contrary, the elliptical locking block 934 does not abut against the discharge pipe 935, and the discharge pipe 935 is in a normal oil-discharging state, avoiding the problem of lubricating oil leakage in the non-oil-adding state.
