DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] For example, see Figures 1 to 6 The utility model provides a micro switch type automobile central door lock, comprising an upper housing 1 and a lower housing 2, wherein the surface of the upper housing 1 is connected to a lock output shaft 18 for fixed axis rotation, and the surface of the upper housing 1 is provided with a refueling component for quantitatively adding lubricating oil to the lock output shaft 18;

[0027] A fixing block 6 is fixedly mounted on the inner wall of the lower housing 2 of the locker, and an insertion rod 5 is fixedly connected to the inner wall of the upper housing 1 of the locker. A fixing component for fixing the insertion rod 5 is arranged in the fixing block 6.

[0028] The refueling component includes a shell 19 fixedly connected to the inner wall of the upper shell 1 of the lock, and a notch is provided on the surface of the shell 19 for the output shaft 18 of the lock to pass through. The lower surface of the shell 19 is evenly provided with a plurality of oil leakage grooves 17 distributed in a circumferential array.

[0029] More specifically, when this embodiment is used, Figure 5 As shown, by regularly adding lubricating oil into the housing 19, the lubricating oil can slide through the multiple oil leakage grooves 17 to the surface of the lock output shaft 18. As the lock output shaft 18 rotates during operation, the lubricating oil can be dispersed to various transmission components in the lock to complete the lubrication of the transmission components.

[0030] Furthermore, the surface of the upper shell 1 of the lock is fixedly connected with an oil delivery pipe 14, the end of the oil delivery pipe 14 extends into the shell 19 and is fixedly connected thereto, the upper surface of the oil delivery pipe 14 is fixedly connected with a funnel 16, the upper surface of the funnel 16 is fixedly connected with an oil storage pipe 13, and the upper surface of the oil storage pipe 13 is fixedly connected with an oil tank 3;

[0031] The surface of the oil storage tube 13 is connected to a rotating rod 12 for fixed axis rotation. The surface of the rotating rod 12 is fixedly connected to four shifting plates 11 distributed in a circumferential array. The end of the rotating rod 12 extending out of the oil storage tube 13 is fixedly connected to a rotating column 4.

[0032] like Figure 5 and Figure 6 As shown, by rotating the rotating column 4 to drive the rotating rod 12 to rotate 90 degrees, the four paddles 11 in the oil storage tube 13 can be rotated 90 degrees, so that the lubricating oil stored between two adjacent paddles 11 can fall into the funnel 16 below, and the lubricating oil in the funnel 16 will enter the housing 19 through the oil delivery pipe 14, and then can fall onto the surface of the output shaft 18 of the lock, so as to lubricate the multiple transmission structures in the lock, thereby extending the service life of the automobile central control door lock.

[0033] Furthermore, the surface of the rotating column 4 is provided with anti-skid patterns, and the surface of the rotating column 4 is fixedly connected with four index fingers 15 distributed in a circular array.

[0034] The upper surface of the oil tank 3 is fixedly connected with a filling pipe, and a sealing plug is provided at the end of the filling pipe.

[0035] It is worth noting that the provision of the anti-skid texture on the surface of the rotating column 4 can increase the friction between the user's hand and the rotating column 4, so that the rotating column 4 can be better rotated. By observing the positions pointed to by the four index fingers 15, the degree of each rotation of the rotating rod 12 can be accurately calculated to 90 degrees. At this time, the amount of lubricating oil dropped between two adjacent shift plates 11 can be just enough to lubricate multiple transmission structures in the lock once, so that quantitative lubrication can be performed, avoiding waste of lubricating oil and making it more practical.

[0036] Embodiment 2, based on the above embodiment,

[0037] Furthermore, the fixing component in the first embodiment is disclosed, and the fixing component includes a circular groove 7 opened on the surface of the fixing block 6 for inserting the insertion rod 5, the inner wall of the circular groove 7 is opened with a rectangular groove, the inner wall of the rectangular groove is provided with a telescopic rod 8, the end of the telescopic rod 8 is fixedly connected with an arc block 10, and a spring 9 is jointly provided between the arc block 10 and the inner wall of the rectangular groove.

[0038] The surface of the insert rod 5 is provided with a sliding groove for the arc block 10 to slide into, and two groups of rectangular notches are provided, and are symmetrically provided with respect to the center of the circular notch 7 .

[0039] More specifically, when this embodiment is used, Figure 3 and Figure 4 As shown, when the upper shell 1 of the lock needs to be installed with the lower shell 2 of the lock, the multiple insertion rods 5 on the inner wall of the upper shell 1 of the lock correspond to the multiple fixing blocks 6 in the lower shell 2 of the lock and are inserted. As the insertion rod 5 is inserted into the circular groove 7, when the insertion rod 5 contacts the arc block 10, the arc block 10 will be squeezed in the direction close to the rectangular groove, and the spring 9 will be compressed. As the insertion of the insertion rod 5 continues, when the slide groove on the surface of the insertion rod 5 contacts the arc block 10, the arc block 10 can be pushed into the slide groove under the action of the elastic potential energy of the spring 9, so that the insertion rod 5 can be fixed in the fixing block 6, so as to complete the fixed installation between the upper shell 1 of the lock and the lower shell 2 of the lock. Compared with the traditional installation method of fixing bolts, the operation is simple and the disassembly is more convenient, which provides convenience for the inspection and replacement of parts in the lock, is more practical, and is worthy of promotion and use.
