Detailed Implementation

[0016] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed description of a lock for use in mines.

[0017] like Figures 1-5 As shown, this utility model discloses a lock for use in mines, comprising a lock body 1; a lock cylinder 2 is disposed inside the lock body 1; a lock tongue 3 is connected to the upper end of the lock cylinder 2; a lock beam 4 is slidably disposed on the upper side of the lock body 1; the lock beam 4 is U-shaped in general; lock pins 5 are disposed on both sides of the lock beam 4 extending into the lock body 1; one lock pin 5 of the lock beam 4 is longer than the other lock pin 5; a first return spring 6 is disposed between the longer lock pin 5 and the lock body 1; a second return spring 66 is disposed between the lock tongue 3 and the lock body 1; a latch 7 is disposed on the shorter lock pin 5 opposite to the lock tongue 3; the shorter lock pin 5 is engaged with the lock tongue 3 through the latch 7; a keyhole 8 is disposed at the lower end of the lock cylinder 2; a rubber sealing sleeve 9 is disposed on the outside of the keyhole 8 on the lock body 1; the rubber sealing sleeve 9 is a sleeve shape with a circular upper part and a flat lower part; an arc-shaped opening 10 with both sides fitting is disposed at the lower end of the rubber sealing sleeve 9; the arc-shaped opening 10 is opposite to the keyhole 8.

[0018] Combination Figures 1-5 As shown, when this lock is used in locations such as power control boxes in mines, a rubber sealing sleeve 9 is provided on the outside of the keyhole 8 on the lower side of the lock body 1. The keyhole 8 is sealed by the arc-shaped opening 10 on both sides of the lower end of the rubber sealing sleeve 9, preventing water vapor, dust, harmful gases and other pollutants in the air from entering the interior of the lock body 1 through the keyhole 8, preventing the internal parts of the lock body 1 from rusting or being corroded, extending the service life of the lock, and maintaining the good performance and reliability of the lock. When the lock is opened with a key, the key is inserted into the arc-shaped opening 10 of the rubber sealing sleeve 9, the two sides of the arc-shaped opening 10 are pushed open, and then the key is inserted into the keyhole 8 opposite to the arc-shaped opening 10. Turning the key drives the lock cylinder 2 to rotate, causing the lock tongue 3 to compress the second return spring 66. The lock tongue 3 disengages from the latch 7, and the lock pin 5 rises under the push of the first return spring 6, completing the opening of the lock. After that, the key is pulled out, and the two sides of the arc-shaped opening 10 on the lower side of the rubber sealing sleeve 9 are re-adhered, resealing the keyhole 8.

[0019] A soft rubber collar 11 is provided on the outer side of the two locking pins 5 at the upper end of the lock body 1. The soft rubber collar 11 fits against the outer wall of the locking pin 5. The soft rubber collar 11 at the upper end of the lock body 1 on the outer side of the two locking pins 5 seals the gap at the connection between the lock body 1 and the locking pin 5, preventing pollutants such as moisture, dust and harmful gases in the air from entering the interior of the lock body 1 through the gap at the connection between the lock body 1 and the locking pin 5. This further protects the parts inside the lock body 1, prevents the parts inside the lock body 1 from rusting or being corroded, increases the stability of the lock, and reduces the maintenance cost of the lock.

[0020] The soft rubber sleeve 11 is vertically provided with a plurality of flow guide grooves 12 on the outer side, when there are condensed water droplets on the lock post 5, in the process of pressing the lock post 5 into the lock body 1 to close, the water droplets on the lock post 5 are blocked by the soft rubber sleeve 11, preventing the water droplets from entering the inside of the lock body 1, the blocked water droplets flow down along the flow guide grooves 12, in the process of moving the lock post 5 up and down, the flow guide grooves 12 provided on the soft rubber sleeve 11 can adjust the tightness of the soft rubber sleeve 11, facilitating the smooth up and down movement of the lock post 5, preventing the lock post 5 from being stuck by the soft rubber sleeve 11.

[0021] The top end of the soft rubber sleeve 11 oppositely provided on the shorter side of the lock post 5 extends inwardly and is provided with a plurality of fan-shaped protective rubber sheets 13, the plurality of protective rubber sheets 13 are combined into a circle and have the same diameter as the inner diameter of the soft rubber sleeve 11, when the lock is in an open state, the shorter side of the lock post 5 will move away from the lock body 1, and the lock body 1 will have a lock hole in the open state relative to the position of the shorter side of the lock post 5, at this time, the plurality of protective rubber sheets 13 will be combined into a circle to seal the position of the lock hole, preventing the lock from being polluted by water vapor, dust, harmful gas and other pollutants through the open lock hole into the inside of the lock, so that the lock has better moisture-proof sealing performance in different use scenarios of closing and opening.

[0022] It can be understood that the utility model is described through some embodiments, and those skilled in the art know that various changes or equivalent replacements can be made to these features and embodiments without departing from the spirit and scope of the utility model.In addition, under the guidance of the utility model, these features and embodiments can be modified to adapt to specific conditions and materials without departing from the spirit and scope of the utility model.Therefore, the utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application belong to the scope protected by the utility model.
