Technical Field

[0001] The utility model relates to the technical field of vehicle lock devices, specifically a dust-proof accessory for a bicycle lock. Background Art

[0002] A bicycle lock is a mechanical locking device specifically used to lock a bicycle, which mainly serves the purpose of anti-theft and preventing the bicycle from accidentally sliding. Since the bicycle is often placed outdoors for a long time when not in use, the bicycle lock will also be in an outdoor environment full of dust for a long time. The bicycle lock placed outdoors for a long time will accumulate a lot of dust, which affects the normal use of the lock. Therefore, it is very necessary to install a dust-proof accessory for the bicycle lock.

[0003] The prior art with the publication number CN209891891U provides a bicycle lock, including: a lock shell; a motor disposed inside the lock shell; an operating member, the motor can drive the operating member to move up and down inside the lock shell; a lock ring, the lock ring includes a first clamping arm and a second clamping arm, the first clamping arm and the second clamping arm form a clamping structure, and the operating member can drive the first clamping arm and the second clamping arm to open or close. The bicycle lock provided by the utility model, the lock ring is composed of two parts, namely the first clamping arm and the second clamping arm, and the first clamping arm and the second clamping arm form a clamping structure. This clamping structure is relatively stable when the bicycle lock is locked or opened, improving the service life and safety of the lock.

[0004] In the above patent, mainly the motor is used to drive the two clamping arms to swing, so as to achieve the purpose of stably opening and closing the bicycle lock. However, this way of opening and closing the bicycle lock uses an electronic opening and closing method, and electronic products need to rely on electric energy to operate. When there is no electric energy supply to the motor, the entire bicycle lock is directly in a state where it cannot be used, and no dust-proof and dust-removing operations are performed on the entire bicycle lock, greatly reducing the practicability of the bicycle lock. Summary of the Utility Model

[0005] In view of the above problems, the utility model provides a dust-proof accessory for a bicycle lock, which is used to solve technical problems such as containing electronic devices and the inability of the bicycle lock to prevent and remove dust.

[0006] To achieve the above object, the present utility model is realized through the following technical solutions: A dust-proof accessory for a bicycle lock, including a lock body of the bicycle lock. An internal component is nested and installed inside the lower end of the lock body. A dust-proof groove is opened on the outer side of the lock body at the position of the internal component in a circular shape. A dust-proof cover is nested and installed on the dust-proof groove. A plurality of dust outlets are opened on the outer side of the lock body near the side of the internal component. The internal component includes an adjusting column and a moving column. Two horizontal shafts penetrate through the moving column. Friction plates are fixedly installed at the upper and lower ends of the two horizontal shafts together. A plurality of the friction plates are fixedly attached with a fitting strip on the side away from the lock body of the bicycle lock, which is used to cooperate with the dust outlets to remove dust. A dust-proof cover is nested and installed on the dust-proof groove for dust-proofing when the bicycle lock is not in use.

[0007] Furthermore, the fitting strip is made of rubber material. This enables the fitting strip to closely adhere to the inner wall of the inner chute of the bicycle lock during sliding, improving the quality of dust removal.

[0008] Furthermore, a layer of nylon fabric is fixedly attached to the surface of the friction plate. This increases the friction when the friction plate contacts the inner wall of the inner chute of the bicycle lock, so that all the dust on the inner wall of the inner chute of the bicycle lock can adhere to the friction plate, improving the quality of dust removal.

[0009] Furthermore, a fastening bolt is fixedly penetrated at a position slightly below the middle of the moving column. The side of the fastening bolt away from the bolt head is fixedly connected with a steel pipe for locking the lower end of the lock body of the bicycle lock.

[0010] Furthermore, a threaded groove is opened in the adjusting column, and a mating thread is opened in the moving column. The outer side of the mating thread is in spiral rotation fit with the inner side of the threaded groove. This allows the adjusting column to rotate and drive the moving column below it to rotate together, improving the operability of the internal structure of the bicycle lock.

[0011] Furthermore, a number of transverse through holes penetrate through the outer surface of the moving column. A bottom groove is opened at the bottom of the moving column. Dome-shaped parts are nested and installed on both sides of the bottom groove. The two dome-shaped parts are connected by a shaft body with a groove around the middle. A number of inner rotating balls are placed in the groove of the shaft body. The outer side of the inner rotating balls is slidably connected with an outer wheel, and the outer wheel can rotate in the bottom groove. Beneficial Effects

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] The utility model slides the friction plate on the inner wall of the lock body through an adjusting column, so as to scrape all the dust on the inner wall of the lock body from the dust outlet, and cooperate with the dust-proof cover always located at the upper end of the built-in component, so that the bicycle lock can perform dust-proof operation whether it is used or not, effectively avoiding the influence on the subsequent normal operation caused by the bicycle lock that cannot dust-proof the sliding groove.

[0022] As Figures 1-5 shown,

[0023] The present utility model provides a dust-proof accessory for a bicycle lock. A dust-proof accessory for a bicycle lock includes a lock body 5 of the bicycle. An internal component 1 is nested and installed inside the lower end of the lock body 5. A dust-proof groove 3 is formed in the outer circle of the lock body 5 at the position of the internal component 1. A dust-proof cover 2 is nested and installed on the dust-proof groove 3. A plurality of dust outlets 4 are formed on the outer side of the lock body 5 near the side of the internal component 1. The internal component 1 includes an adjusting column 11 and a moving column 13. Two horizontal axes penetrate through the moving column 13. Friction plates 14 are fixedly installed up and down at both ends of the two horizontal axes. A fitting strip 15 is fixedly attached to the side of the plurality of friction plates 14 away from the lock body 5 for cooperating with the dust outlets 4 to remove dust. The fitting strip 15 is made of rubber material. A layer of nylon fabric is fixedly attached to the surface of the friction plate 14. A fastening bolt 12 is penetrated and fixed at a position slightly below the middle of the moving column 13. A steel pipe 16 is fixedly connected to the side of the fastening bolt 12 away from the bolt head for locking the lower end of the lock body 5. A threaded groove 111 is formed in the adjusting column 11. A mating thread 131 is formed in the moving column 13. The outer side of the mating thread 131 and the inner side of the threaded groove 111 are in screw rotation fit. A plurality of horizontal through holes 132 penetrate through the outer surface of the moving column 13. A bottom groove 133 is formed at the bottom of the moving column 13. Dome-shaped members 136 are nested and installed on both sides of the bottom groove 133. The two dome-shaped members 136 are connected by a shaft body with a groove in the middle. A plurality of inner rotating balls 134 are placed in the groove of the shaft body. The outer side of the inner rotating balls 134 is slidably connected to an outer wheel 135. The outer wheel 135 can rotate in the bottom groove 133.

[0024] Among them, the inner diameter of the thread in the threaded groove 111 and the outer diameter of the thread of the mating thread 131 are the same and can cooperate with each other, so that the adjusting column 11 can be smoothly screwed into the mating thread 131.

[0025] Among them, when the user rotates the adjusting column 11, it is necessary to press the adjusting column 11 forcefully towards the direction of the bicycle lock, so that the adjusting column 11 does not displace relative to the bicycle lock, but instead makes an idle rotation without displacement. When the adjusting column 11 is operating, it is not fully screwed into the mating thread 131 for fixation, but only screwed in halfway, so that when the user rotates the adjusting column 11, the height of the friction plate 14 can be adjusted, thereby adjusting the height of cleaning dust.

[0026] Among them, at the position inside the outer wheel 135 near the inner rotating ball 134, there is a circular inner groove that is consistent with the outer side of the dome 136, so that a plurality of inner rotating balls 134 are all located in the annular groove formed by the outer wheel 135 and the shaft body groove connecting the dome 136, so as to enable the outer wheel 135 to rotate around the shaft body connecting the dome 136.

[0027] Among them, there are no any electronic components inside the bicycle lock, so that the bicycle lock can be used conveniently and can also be used continuously for a long time to the maximum extent.

[0028] The working principle of the present utility model is described as follows: When the bicycle lock is not in use, the user directly covers the dust cover 2 on the dust slot 3. At this time, the dust cover 2 can completely cover the arc-shaped groove on the surface of the bicycle lock, preventing dust from entering the bicycle lock. Thus, it serves as a dust-proof accessory for the bicycle lock. When the bicycle lock is in use, the user first directly removes the dust cover 2 from the dust slot 3. Then, the user grabs the adjustment column 11 and swings it up and down along the arc-shaped groove on the bicycle lock first, and finally swings it downward until the steel pipe 16 is inserted into the key socket at the other end of the bicycle lock and then stops. At this time, the steel pipe 16 will directly be inserted into the locking structure for fixation until the user inserts the key into the key socket to unlock. Since the key locking structure is a very mature existing technology, the present utility model does not elaborate on it. The user can rotate the adjustment column 11 according to the specific usage situation. The rotated adjustment column 11 cannot move up and down due to the inward pressure of the user. It rotates along the outer circle of the thread 131 through the thread groove 111, causing the moving column 13 to move up and down, thereby achieving the purpose of adjusting the height for cleaning dust. When the adjustment column 11 slides in the inner groove of the bicycle lock, since its bottom always contacts the bottom of the inner groove of the bicycle lock, the outer wheel 135 can rotate around the connecting shaft of the two domes 136 through the inner rotating ball 134, thereby improving the smoothness of the movement of the adjustment column 11 driving the steel pipe 16. During the process of the adjustment column 11 sliding in the inner groove of the bicycle lock, the two friction plates 14 always contact the inner side walls of the inner groove of the bicycle lock and generate friction, and the fitting strips 15 can fit more closely to the inner side walls of the inner groove of the bicycle lock until the friction plates 14 and the fitting strips 15 cooperate to send all the dust in the inner groove of the bicycle lock out from the dust outlet 4, and complete the dust-proof and dust-removing treatment of the entire bicycle lock.

[0029] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0030] Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
