Description

Technical Field

[0001] The utility model relates to a lock, in particular to a door lock with a key lubrication function. Background Art

[0002] A door lock is a device used to lock a door to prevent others from opening it. There are many types of door locks, and the requirements for door locks are different in different occasions. In the civilian field, door locks can be roughly divided into mechanical door locks and smart door locks. Among them, mechanical door locks are widely used because of their reliable structure, high safety and low cost. Traditional mechanical door locks are mainly composed of a panel, a handle arranged on the front side of the panel, a keyhole, and a lock core arranged on the back side of the panel. Among them, the keyhole is linked to the lock core. When the matching key is inserted into the keyhole and rotated at a corresponding angle, the door lock can be switched to an unlocked state. At this time, turning the handle can drive the lock tongue to retract to achieve the door opening action. For example, the utility model patent with announcement number CN208236140U discloses a similar mechanical door lock.

[0003] The above-mentioned mechanical door lock is prone to wear and dust jam as the key and keyhole are used for a longer period of time, causing jams when inserting and removing the key. In severe cases, it may affect the normal use of the door lock, so there is room for improvement. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a door lock with a key lubrication function. By inserting the insertion portion of the key into the cavity, the insertion portion can produce relative displacement with the bristles on both sides of the cavity, so that the lubricant on the bristles can be filled to the outer surface of the insertion portion, thereby lubricating the insertion portion of the key, thereby improving the unlocking experience and efficiency.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A door lock with a key lubrication function comprises a panel, a handle arranged on the front side of the panel, a keyhole, and a key. The handle comprises a driving rod rotatably arranged on the panel and a holding rod vertically arranged at one end of the driving rod away from the panel. A cavity is provided at a position of the holding rod away from the driving rod, and bristles are provided on both side walls of the cavity parallel to the length direction of the holding rod, and lubricant is distributed on the bristles. An insertion hole is provided at one end of the holding rod away from the driving rod for an insertion portion of the key to enter the cavity along the length direction of the holding rod. When the insertion portion of the key is inserted into the cavity through the insertion hole, the insertion portion can produce relative displacement with the bristles, so that the lubricant on the bristles is replenished to the outer surface of the insertion portion.

[0007] By adopting the above scheme, when the key gets stuck during use, the insertion part of the key is inserted into the cavity through the insertion hole, which can cause relative displacement between the insertion part and the bristles on both sides of the cavity, so that the lubricant on the bristles can be filled to the surface of the insertion part, thereby lubricating the insertion part, thereby improving the unlocking experience and efficiency.

[0008] Preferably, a feeding port connected to the containing cavity is provided on the upper surface of the holding rod, and a sealing cover is provided on the feeding port.

[0009] With the above solution, the feeding port can facilitate users to add lubricant to the bristles in the cavity, and the cover can seal the feeding port to prevent external dust from entering the cavity and prevent the lubricant in the cavity from spilling out.

[0010] Preferably, two side walls in the cavity corresponding to the bristles are vertically slidably clamped with mounting plates, and the two groups of bristles are respectively arranged on opposite plate surfaces of the two mounting plates.

[0011] The above solution can facilitate users to disassemble and clean the bristles, and also facilitate users to add lubricants.

[0012] Preferably, both sides of the side walls of the cavity corresponding to the bristles are vertically provided with sliding grooves for slidingly engaging the two side edges of the mounting plate.

[0013] By adopting the above solution, the sliding groove and the two side edges of the mounting plate are engaged with each other in a sliding manner, and the structure is simple. This can not only realize the efficient disassembly and assembly of the mounting plate, but also ensure the stability of the mounting plate after installation.

[0014] Preferably, both downstream corners of the mounting plate are rounded.

[0015] With the above solution, the rounded corners can play a guiding role, thereby improving the installation efficiency and convenience of the installation plate.

[0016] Preferably, the upper side of the mounting plate is fixed to the covering surface of the cover.

[0017] By adopting the above solution, when the cover is opened, the mounting plate can be taken out from the corresponding slide slot simultaneously, eliminating the trouble of removing the mounting plate separately, and further improving the operation efficiency and convenience.

[0018] Preferably, an elastic connector is connected between the mounting plate and the cover so that the mounting plate tends to be perpendicular to the covering surface of the cover and the mounting plate can be expanded outwards under the action of external force.

[0019] With the above solution, the elastic connector can facilitate the user to flip the mounting plate outward, thereby facilitating the user to add lubricant to the bristles. At the same time, when the external force is removed, the elastic connector can drive the mounting plate to return to a state perpendicular to the cover surface, so that the mounting plate can be installed in the corresponding slide groove with the cover, further improving the operation efficiency and convenience.

[0020] Preferably, a gripping piece is provided on the upper surface of the cover.

[0021] By adopting the above solution, the gripping piece is more easily stressed, further improving the efficiency and convenience of disassembly and assembly of the cover.

[0022] Preferably, a sealing plug is provided on the socket.

[0023] By adopting the above solution, the sealing plug can improve the sealing performance of the plug hole, prevent the lubricant in the cavity from leaking out of the plug hole, and is more humane.

[0024] The utility model has a significant technical effect due to the adoption of the above technical solution: when the key is stuck during use, the insertion part of the key is inserted into the cavity through the insertion hole, which can cause relative displacement between the insertion part and the bristles on both sides of the cavity, so that the lubricant on the bristles can be filled to the surface of the insertion part, thereby lubricating the insertion part, thereby improving the unlocking experience and efficiency.

DETAILED DESCRIPTION

[0033] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] like Figures 1 to 4 As shown, the present embodiment discloses a door lock with a key lubrication function, comprising a panel 1, a handle 2 arranged on the front side of the panel 1, a keyhole 3, and a key 4 matched with the keyhole 3. Specifically, the handle 2 comprises a driving rod 5 rotatably arranged on the panel 1 and a holding rod 6 vertically arranged at the end of the driving rod 5 away from the panel 1. A rectangular cavity 7 is provided at a position of the holding rod 6 away from the driving rod 5. Bristles 8 are provided on both side walls of the cavity 7 parallel to the length direction of the holding rod 6. Lubricant is distributed on the bristles 8, and the lubricant is preferably graphite powder. An insertion hole 11 is provided at the end of the holding rod 6 away from the driving rod 5 for the insertion portion 10 of the key 4 to enter the cavity 7 along the length direction of the holding rod 6. The insertion hole 11 is in a vertical strip shape, so that the insertion portion 10 of the key 4 can enter the cavity 7 in a longitudinal posture, so that the two side surfaces of the insertion portion 10 can fully contact the bristles 8 on both sides of the cavity 7. In this embodiment, when the insertion portion 10 of the key 4 is inserted into the cavity 7 through the insertion hole 11, the insertion portion 10 can produce relative displacement with the bristles 8, so that the lubricant on the bristles 8 is replenished to the outer surface of the insertion portion 10, thereby lubricating the insertion portion 10 of the key 4.

[0035] like Figure 2 As shown, in order to facilitate the user to add lubricant to the bristles 8 in the cavity 7, a rectangular feeding port 12 connected to the cavity 7 is provided on the upper surface of the gripping rod 6, and a rectangular cover 13 is covered on the feeding port 12. The size of the cover 13 is larger than the feeding port 12, so that it can completely cover the feeding port 12, thereby ensuring its sealing performance.

[0036] like Figure 3 As shown, in order to facilitate the cleaning of the bristles 8 and the addition of lubricant, the two side walls corresponding to the bristles 8 in the cavity 7 are vertically slidably connected with mounting plates 14, and the two groups of bristles 8 are respectively arranged on the opposite plate surfaces of the two mounting plates 14. Specifically, the two sides of the side walls corresponding to the bristles 8 in the cavity 7 are vertically opened with slide grooves 15 for the two side edges of the mounting plates 14 to slide and connect.

[0037] like Figure 3As shown, in order to improve the efficiency and convenience of disassembly and assembly of the mounting plate 14, two corners at the downstream of the mounting plate 14 are provided with rounded corners 16. The upper side of the mounting plate 14 is fixed to the covering surface of the cover 13.

[0038] like Figure 5 and Figure 6 As shown, in order to facilitate the user to add lubricant to the bristles 8, an elastic connector 17 is connected between the mounting plate 14 and the cover 13 so that the mounting plate 14 has a tendency to be perpendicular to the covering surface of the cover 13, and the mounting plate 14 can be expanded outward under the action of external force. The elastic connector 17 is preferably a stainless steel spring and is integrally arranged with the cover 13 and the mounting plate 14.

[0039] like Figure 2 As shown, in order to improve the efficiency and convenience of disassembly and assembly of the cover 13 and the mounting plate 14, a gripping member 18 is provided on the upper surface of the cover 13, and the gripping member 18 is a pull ring pivotally connected to the upper surface of the cover 13. It can not only ensure the force effect of the cover 13, but also realize the storage of the gripping member 18, thereby reducing the space occupied by the gripping member 18.

[0040] like Figure 2 and Figure 7 As shown, in order to improve the sealing performance of the jack 11, a sealing plug 19 is provided on the jack 11. Specifically, the sealing plug 19 includes a rubber plug 20 inserted into the jack 11 by interference fit and a rubber sealing sheet 21 integrally connected to the rubber plug 20 and covering the end of the gripping rod 6 away from the driving rod 5.

[0041] The specific usage process is as follows:

[0042] When the key 4 is stuck during use, first pull out the rubber plug 20 from the socket 11 with the help of the rubber sealing sheet 21, then completely insert the insertion part 10 of the key 4 into the cavity 7 through the socket 11, and allow the key 4 to be inserted and pulled back and forth in the socket 11, so that the insertion part 10 can repeatedly produce relative displacement with the bristles 8 on both sides of the cavity 7, so that the lubricant on the bristles 8 can be filled to the surface of the insertion part 10, and then the insertion part 10 of the key 4 is lubricated. After lubrication, pull out the insertion part 10 of the key 4 from the cavity 7 and the socket 11, and re-cover the sealing plug 19. At this time, the lubricated key 4 will cooperate more smoothly with the keyhole 3 on the front side of the panel 1, thereby improving the user experience and efficiency.

[0043] When the lubricant on the bristles 8 is exhausted, the cover 13 is lifted with the help of the gripping member 18 to drive the two mounting plates 14 on the cover 13 to be lifted at the same time, thereby realizing the disassembly of the mounting plates 14 and the bristles 8. After the bristles 8 are disassembled, the mounting plates 14 are unfolded outwards by overcoming the elastic force of the elastic connector 17 to expose the bristles 8 on the mounting plates 14, and then the lubricant (graphite powder) is sprayed on the bristles 8. When the bristles 8 on the two mounting plates 14 are all lubricated, the elastic connector 17 drives the mounting plates 14 to return to a state perpendicular to the covering surface of the cover 13. At this time, the two mounting plates 14 on the cover 13 can be slidably engaged in the corresponding slide grooves 15 respectively with the help of the fillets 16, and then the cover 13 is pressed down to drive the two mounting plates 14 to completely enter the receiving grooves, and the covering of the cover 13 is completed at the same time. In this state, the cover 13 can stably cover the feeding port 12 by means of the interference fit between the edge of the mounting plate 14 and the slide groove 15 , thereby completing the installation of the mounting plate 14 and the cover 13 .
