Description

Technical Field

[0001] This utility model relates to the field of anti-loosening mounting bracket technology, and in particular to an anti-loosening mounting bracket for magnetic locks. Background Technology

[0002] A magnetic lock mounting bracket is a tool used to install magnetic locks on top of wooden or heavy metal doors. It assists the magnetic lock in locking and unlocking the door, ensuring the safety of the interior. However, during the operation of the magnetic lock, the mounting bracket is subjected to vibrations from opening and closing the door. Over time, this can cause wear on the bolts securing the bracket. Furthermore, the bolt connections are exposed to air and are susceptible to corrosion from unknown corrosive particles, leading to oxidation and rust. This results in reduced bolt preload, loosening of the bolts, and ultimately, instability of the magnetic lock mounting bracket, preventing the magnetic lock from opening and closing. Utility Model Content

[0003] In view of the above-mentioned problems in the prior art, this utility model is proposed.

[0004] The purpose of this utility model is to provide a mounting bracket for preventing loosening of magnetic locks, which aims to solve the problem that after long-term use, the bolt connection of the bracket will oxidize and rust, leading to loosening of the bolts and instability of the bracket.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a mounting bracket for preventing loosening of a magnetic lock, comprising a bracket housing and a bottom shell including bolts and hinged to the bottom of the bracket housing;

[0006] The oiling unit includes an oil delivery assembly disposed on the top right side of the bottom shell, a rotating wiping assembly disposed between the bracket housing and the bolt, and an oil spraying assembly disposed on the top of the oil delivery assembly;

[0007] The oil supply unit includes an oil tank located at the top front side of the bottom shell and an oil inlet pipe that penetrates and is fixedly connected to the front side of the support housing.

[0008] As a preferred embodiment of the present invention for a magnetic lock anti-loosening mounting bracket, the oil supply assembly includes: a pressure cylinder disposed between the bottom shell and the bolt; a semi-annular hollow plate symmetrically disposed at the bottom of the bolt; an oil supply hose sleeved between the pressure cylinder and the semi-annular hollow plate; a piston rod slidably disposed on the right side of the pressure cylinder; a push rod disposed at the right end of the piston rod for squeezing and pushing; a piston rod disposed between the left inner wall of the pressure cylinder and the piston rod; and a one-way valve disposed between the output end of the pressure cylinder and the input end of the oil supply hose.

[0009] The right end of the push rod penetrates and slides through the inner wall of the bracket housing.

[0010] As a preferred embodiment of the present invention for a magnetic lock anti-loosening mounting bracket, the rotating wiping assembly includes an L-shaped fixing rod symmetrically and fixedly connected to the right end of the piston rod, a first inclined triangular slider symmetrically arranged on the top right side of the bottom shell, a second inclined triangular slider slidably arranged on the inclined surface of the first inclined triangular slider, a semi-toothed groove-shaped slide rod arranged on the top of the second inclined triangular slider, a fixing block slidably arranged on the lower cylindrical outer wall of the semi-toothed groove-shaped slide rod, an annular slide rail symmetrically arranged between one side of the inner top wall of the bracket housing and the bolt thread surface, an arc-shaped slider slidably arranged on the outer wall of the annular slide rail, a semi-annular toothed rack meshing with one side of the top toothed groove of the semi-toothed groove-shaped slide rod, and a wiping plate embedded in the inner ring wall of the semi-annular hollow plate;

[0011] The right side of the fixing block is fixedly connected to the inner wall of the bracket housing, the outer ring wall of the semi-annular hollow plate is fixedly connected to the inner ring wall of the semi-annular rack, and both sides of the semi-annular hollow plate are fixedly connected to the arc-shaped slider.

[0012] As a preferred embodiment of the present invention for a magnetic lock anti-loosening mounting bracket, the oil spraying assembly includes: an angled slide rod 1 extending and symmetrically arranged in the inner cavity of the semi-annular hollow plate; an angled slide rod 2 slidably arranged on the top inclined surface of the angled slide rod 1; a tension spring 1 arranged between the inner bottom wall of the oil spraying assembly and the top inclined triangular head of the angled slide rod 1; a tension spring 2 arranged between one end of the inclined triangular head of the angled slide rod 2 and the inner wall of the semi-annular hollow plate; a square slider 1 fixedly connected to one end of the angled slide rod 2; a square slider 2 slidably arranged on one side of the square slider 1; an angled slide rod 3 arranged on one side of the square slider 2; and a tension spring 3 arranged between the inclined triangular head of the angled slide rod 3 and the inner wall of the oil spraying assembly.

[0013] As a preferred embodiment of the present invention for the anti-loosening mounting bracket of magnetic lock, the oil supply unit further includes an oil sealing cap disposed on the top of the oil inlet pipe, an oil delivery hose II sleeved on the output end of the oil tank, and a one-way valve II disposed between the output end of the oil delivery hose II and the inner wall of the front side of the pressure cylinder.

[0014] The beneficial effects of this utility model for the anti-loosening mounting bracket of magnetic locks are as follows:

[0015] 1. By setting up an oil-pushing unit, under the pressure of the push rod, the piston rod can be driven to indirectly push the lubricating oil in the oil cylinder into the inner cavity of the semi-annular hollow plate. This allows the oil spraying nozzle assembly to spray the molybdenum disulfide oil used for lubrication onto the connection between the bolt and the bracket housing. Under the indirect push of the L-shaped fixing rod, the semi-annular hollow plate can drive the wiping plate to rotate and wipe along the surface of the bolt, thus achieving the effect of spraying and wiping. This achieves lubrication and maintenance of the bolt connection, avoiding the problems of oxidation, rust, severe wear, and bolt loosening caused by the bolts being tightened in the bracket housing for a long time due to the infiltration of unknown corrosive particles in the air. It reduces the corrosion of corrosive particles in the air, improves the service life of the bolt surface, enhances the strength of the bolts to tighten the bracket housing without rust, and improves the effect of bolts not loosening.

[0016] 2. By setting up an oil supply unit, under the action of the compression spring's rebound force, the piston rod can be indirectly driven to draw molybdenum disulfide oil from the oil tank through the second oil supply hose. Then, the second oil supply hose guides the molybdenum disulfide oil into the pressure cylinder, thereby realizing the oil replenishment operation. This avoids the problem that the molybdenum disulfide oil cannot be replenished for lubrication after the bolt has been used for a long time after the first lubrication. After the molybdenum disulfide oil in the oil tank is used up, the oil inlet can be opened by turning the knob to seal the oil cap, thereby improving the efficiency of bolt lubrication replenishment.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0032] Example 1

[0033] Reference Figures 1 to 5 As shown, this is the first embodiment of the present utility model. This embodiment provides a mounting bracket for preventing loosening of a magnetic lock, including a bracket housing 1 and a bolt 11 that passes through the bracket housing 1. The bolt 11 is used to fix the bracket housing 1 to the top of the door frame.

[0034] The oil-pushing unit 2 includes an oil delivery assembly 21 disposed on the top of the bracket housing 1, a push rod 211 that penetrates the bottom outer wall of the bracket housing 1, a piston rod 212 fixedly disposed at one end of the push rod 211, a pressure cylinder 213 slidably disposed at one end of the piston rod 212, two sets of oil delivery hoses 214 sleeved on the output end of the pressure cylinder 213, an arc plate 215 sleeved on the output end of the oil delivery hoses 214, an oil nozzle assembly 23 embedded in the inner ring surface of the arc plate 215, the output port of the oil nozzle assembly 23 being located at the connection between the bracket housing 1 and the bolt 11, and a rotating wiping assembly 22 disposed between the bracket housing 1 and the bolt 11. The pushing and pulling force of the push rod 211 is generated by the door opening and closing action.

[0035] The oil supply unit 3 includes an oil tank 33 disposed on the inner wall of the front side of the bracket housing 1, and an oil supply hose 34 sleeved on the output end of the oil tank 33.

[0036] The oil delivery assembly 21 also includes a one-way valve 217 disposed between the output end of the oil cylinder 213 and the input end of the oil delivery hose 214, and a one-way valve 35 disposed between the output end of the oil delivery hose 34 and the inner wall of the front side of the oil cylinder 213. The one-way valve 217 is used to control the oil inlet process of the oil delivery hose 214, and the one-way valve 35 is used to control the oil delivery process of the oil delivery hose 34.

[0037] It should be noted that the oil in the oil tank 33 and the pressure cylinder 213 is molybdenum disulfide oil. Molybdenum disulfide oil is used to lubricate the connection between the bolt 11 and the bracket housing 1, increasing the wear resistance and oxidation resistance of this connection. The right end of the push rod 211 penetrates and slides through the inner wall of the bracket housing 1, while the left end of the push rod 211 is fixedly connected to the piston rod 212. The outer surface of the piston rod 212 penetrates and slides through the right side of the pressure cylinder 213, and the left side of the piston rod 212 is fixedly connected to the compression spring 216. The left end of the spring 216 is fixedly connected to the left inner wall of the oil cylinder 213. The output end of the oil cylinder 213 is connected to both oil delivery hoses 214. At the same time, the output end of the oil delivery hoses 214 is connected to the bottom of the arc plate 215 through and fixedly connected. The purpose is to guide the molybdenum disulfide oil in the oil cylinder 213 into the arc plate 215 to complete the oil delivery operation. The one-way valve 217 is fixedly connected to the passage position between the input end of the oil delivery hose 214 and the output end of the oil cylinder 213. The purpose is to control the output dosage of the molybdenum disulfide oil.

[0038] When in use, first open the bottom of the bracket housing 1, place the required parts in the preset position inside the bracket housing 1, then close the bottom of the bracket housing 1, then place the bracket housing 1 on the top of the door frame where the magnetic lock is to be installed, then penetrate the bracket housing 1 with the bolt 11 and nail it with a hammer to complete the fastening operation of the bracket housing 1. At this time, the right end of the push rod 211 is flush with the outside side of the door frame.

[0039] When the door is closed, it presses the push rod 211 to the left, causing the push rod 211 to push the piston rod 212 into the inner cavity of the pressure cylinder 213. At the same time, the piston rod 212 presses the compression spring 216 to the left to retract and store force, and the piston rod 212 can squeeze the molybdenum disulfide oil in the pressure cylinder 213 to the one-way valve 217. At this time, the small ball in the one-way valve 217 can gradually open the inlet of the one-way valve 217 under the action of the leftward flow force of the molybdenum disulfide oil. The molybdenum disulfide oil can then be squeezed by the piston rod 212 into the two oil delivery hoses 214, and further, the two oil delivery hoses 214 can guide the molybdenum disulfide oil into the two arc plates 215, thereby completing the oil delivery operation.

[0040] When the door is opened, the right end of the compression spring 216, which is in the compression storage phase, starts to push the piston rod 212 to slide to the right. At this time, the piston rod 212, which moves to the right, can form a suction state on the sealed inner cavity at the left end of the pressure cylinder 213. This suction space in the pressure cylinder 213 can pull the small ball in the one-way valve 217 to gradually block the inlet of the one-way valve 217, so that the space in the oil hose 214 and the space in the pressure cylinder 213 form a temporary closed isolation state.

[0041] In summary, the push rod 211 powerfully pushes the piston rod 212, which in turn indirectly pushes the molybdenum disulfide oil agent in the oil cylinder 213 into the arc plate 215. This ensures that the oil can be conveyed in a certain amount during the oil delivery process, reducing the problem of unstable output of molybdenum disulfide oil agent and improving the delivery efficiency and accuracy of molybdenum disulfide oil agent.

[0042] like Figures 1 to 5As shown, in a preferred embodiment, the rotating wiping assembly 22 includes an L-shaped fixing rod 221 symmetrically arranged at the right end of the piston rod 212, a first inclined triangular slider 222 symmetrically arranged at one end of the L-shaped fixing rod 221, a second inclined triangular slider 223 slidably arranged on the inclined surface of the first inclined triangular slider 222, a semi-toothed slide rod 225 arranged at the top of the second inclined triangular slider 223, a fixing block 224 slidably arranged on the lower cylindrical outer wall of the semi-toothed slide rod 225, an annular slide rail 228 symmetrically arranged between one side of the inner top wall of the bracket housing 1 and the threaded surface of the bolt 11, an arc-shaped slider 229 slidably arranged on the outer wall of the annular slide rail 228, a semi-annular rack 226 meshing with one side of the top toothed groove of the semi-toothed slide rod 225, and a wiping plate 227 embedded in the inner annular wall of the arc plate 215.

[0043] The right side of the fixed block 224 is fixedly connected to the inner wall of the bracket housing 1, the outer ring wall of the arc plate 215 is fixedly connected to the inner ring wall of the semi-annular rack 226, and both sides of the arc plate 215 are fixedly connected to the arc slider 229.

[0044] It should be noted that the ends of the two L-shaped fixing rods 221 near the push rod 211 are fixedly connected to the piston rod 212, and the other end of the L-shaped fixing rod 221 is fixedly connected to the right side of the first inclined triangular slider 222. The inclined surface of the first inclined triangular slider 222 is slidably connected to the second inclined triangular slider 223. The top of the second inclined triangular slider 223 is fixedly connected to the bottom of the slide rod of the semi-toothed slide rod 225. The toothed part at the top of the semi-toothed slide rod 225 is engaged with the semi-annular rack 226. The side of the annular slide rail 228 near the bolt 11 is fixedly connected to the inner wall of the bracket housing 1. The side of the annular slide rail 228 near the arc plate 215 is slidably engaged with the arc slider 229.

[0045] In use, as the piston rod 212 moves to the left, it pulls the second inclined triangular slider 223 to the left, causing the second inclined triangular slider 223 to push the first inclined triangular slider 222 to the left. This force gradually compresses the second inclined triangular slider 223, causing it to move upwards along the inclined surface of the first inclined triangular slider 222. Simultaneously, the second inclined triangular slider 223 pushes the semi-toothed grooved slide rod 225 upwards, causing the lower part of the semi-toothed grooved slide rod 225 to slide upwards along the inner wall of the fixed block 224, further causing the semi-toothed grooved slide rod 225 to... The toothed portion at the top of the slide bar 225 can engage and push the semi-annular rack 226 to rotate. This causes the semi-annular rack 226 to drive the arc plate 215 to rotate, which in turn drives the wiping plate 227 to rotate. As the wiping plate 227 rotates, it can wipe along the threaded surface of the bolt 11, further wiping away dust and impurities from the surface of the bolt 11 and the bolt connection, thus preparing for oil spraying and lubrication. This reduces the interference of excess impurities on the bolt connection and improves the sensitivity of the bolt connection without damage.

[0046] In summary, under the pulling force of the L-shaped fixing rod 221 driven by the piston rod 212, the L-shaped fixing rod 221 can indirectly drive the arc plate 215 to rotate the wiping plate 227. This allows the wiping surface of the wiping plate 227 to be in close contact with the surface of the bolt 11 and the connection part of the bolt 11 for the first rotational wiping operation, thereby enhancing the strength of the bolt 11 to fasten the bracket housing 1 without damage.

[0047] like Figures 1 to 5 As shown, in a preferred embodiment, the fuel injector assembly 23 includes an angled slide bar 231 that extends and is symmetrically disposed within the inner cavity of the arc-shaped plate 215; an angled slide bar 233 that is slidably disposed on the top inclined surface of the angled slide bar 231; a tension spring 232 disposed between the inner bottom wall of the fuel injector assembly 23 and the top triangular head of the angled slide bar 231; a tension spring 234 disposed between one end of the triangular head of the angled slide bar 233 and the inner wall of the arc-shaped plate 215; a square slider 235 fixedly disposed at one end of the angled slide bar 233; a square slider 236 slidably disposed on one side of the square slider 235; an angled slide bar 237 disposed on one side of the square slider 236; and a tension spring 238 disposed between the triangular head of the angled slide bar 237 and the inner wall of the fuel injector assembly 23.

[0048] It should be noted that both angled sliders 231 penetrate and are slidably connected to the inner wall of the fuel injector assembly 23. A tension spring 232 is fixedly connected to the bottom of the upper triangular head of one of the angled sliders 231. The lower end of the tension spring 232 is fixedly connected to the inner bottom wall of the fuel injector assembly 23. The inclined surface of the upper triangular head of the angled slider 231 is slidably connected to the angled slider 233. One side of the triangular head of the angled slider 233 is fixedly connected to the inner wall of the fuel injector assembly 23 by a tension spring 234. The side of the square slider 235 closest to the inner wall of the fuel injector assembly 23 is fixedly connected to the tension spring 234. The outer surface of slider 1 235 is slidably connected to the fuel injector assembly 23 at the fuel injector port. The outer surface of square slider 2 236 is slidably connected to the fuel injector assembly 23 at the fuel injector port. Square slider 1 235 and square slider 2 236 are symmetrically distributed. The side of square slider 2 236 near the inner wall of the fuel injector assembly 23 is fixedly connected to the angled slider 3 237. The two ends of tension spring 3 238 are fixedly connected to one side of the triangular head of angled slider 3 237 and the inner wall of the fuel injector assembly 23, respectively. The inclined surface of the triangular head of angled slider 3 237 is slidably connected to another angled slider 1 231.

[0049] In use, the piston rod 212 pushes the molybdenum disulfide oil in the hydraulic cylinder 213 into the arc plate 215 under the leftward thrust of the push rod 211. Under the continuous thrust of the piston rod 212, the arc plate 215 delivers the molybdenum disulfide oil to the nozzle assembly 23. The nozzle assembly 23 then sprays the molybdenum disulfide oil onto the surface of the bolt 11 and the bolt connection, achieving localized lubrication. The rotation of the arc plate 215 ensures that the nozzle assembly 23 evenly sprays the molybdenum disulfide oil onto the surface of the bolt 11 and the bolt connection. Simultaneously, the wiping action of the wiping plate 227 spreads the sprayed molybdenum disulfide oil evenly, forming a complete anti-oxidation layer on the bolt connection, thus achieving lubrication and maintenance of the bolt connection. As a result, under the continuous flow of molybdenum disulfide oil in the inner cavity of the arc plate 215, the thrust generated by the continuous flow of molybdenum disulfide oil can push the two angled slide rods 1 231 upward, thereby causing the two angled slide rods 1 231 to simultaneously push the angled slide rod 233 to slide to the left and the angled slide rod 3 237 to slide to the right. This allows the angled slide rod 233 to push the square slider 1 235 to slide to the left, and the angled slide rod 3 237 to push the square slider 236 to move to the right. Therefore, the square sliders 1 235 and 236 sliding in opposite directions will gradually merge the nozzles of the oil injection assembly 23, thereby controlling the dosage of molybdenum disulfide oil sprayed from the oil injection assembly 23, avoiding excessive spraying of molybdenum disulfide oil and causing waste, improving the sensitivity of the oil injection operation of the oil injection assembly 23, and enhancing the oil injection lubrication force of the oil injection assembly 23.

[0050] In summary, under the continuous pushing and squeezing action of the push rod 211, the piston rod 212 can indirectly push the lubricating oil in the oil cylinder 213 into the inner cavity of the arc plate 215. This allows the oil spray nozzle assembly 23 to spray the molybdenum disulfide oil used for lubrication onto the connection part of the bolt 11. Under the indirect pushing of the L-shaped fixing rod 221, the arc plate 215 can drive the wiping plate 227 to rotate and wipe the connection part of the bolt 11 along the surface, thus achieving the effect of spraying and wiping. This achieves lubrication and maintenance of the connection part of the bolt 11, avoiding the problem of oxidation, rust, severe wear, and loosening of the bolt 11 connection part due to the contamination of unknown corrosive particles in the air after the bolt 11 has been tightened for a long time. It reduces the corrosion of corrosive particles in the air, improves the service life of the bolt 11 surface, enhances the strength of the bolt 11 to fasten the bracket housing 1 without rust, and improves the effect of the bolt 11 without loosening.

[0051] like Figure 2 and Figure 5As shown, in a preferred embodiment, the oil supply unit 3 further includes an oil sealing cap 31 disposed on the top of the oil inlet pipe 32, and an oil inlet pipe 32 sleeved on the top of the oil tank 33.

[0052] It should be noted that the oil tank 33 is fixedly connected to the front inner wall of the bracket housing 1, the top of the oil tank 33 is fixedly connected to the output end of the oil inlet pipe 32, the outer surface of the oil inlet pipe 32 penetrates the bracket housing 1 and is fixedly connected to the input end of the oil inlet pipe 32, and the oil sealing cap 31 is threadedly connected to it. The output end of the oil tank 33 is fixedly connected to the second oil delivery hose 34, the front outer wall of the pressure cylinder 213 is fixedly connected to the output end of the second oil delivery hose 34, and the second check valve 35 is fixedly connected to the passage position between the input end of the first oil delivery hose 214 and the output end of the pressure cylinder 213.

[0053] When using, first unscrew the oil cap 31, then inject molybdenum disulfide oil into the output end of the oil inlet pipe 32. Under the guidance of the pipe inside the oil inlet pipe 32, the oil inlet pipe 32 can guide the injected molybdenum disulfide oil into the inner cavity of the oil tank 33. After the inner cavity of the oil tank 33 is full, stop the liquid injection operation, and then manually unscrew the oil cap 31 to seal the inlet of the oil inlet pipe 32.

[0054] When the door is opened, the piston rod 212 is continuously pushed back to the right by the compression spring 216, causing the cavity in the oil cylinder 213 to form a suction state. Therefore, the suction in the oil cylinder 213 can attract the small ball in the one-way valve 35 to gradually open the output port of the one-way valve 35, so that the oil delivery hose 34 can generate suction at the same time. This allows the oil delivery hose 34 to guide the molybdenum disulfide oil in the oil tank 33 into the oil cylinder 213, thereby realizing the oil replenishment operation. When the compression spring 216 fully pushes the left end of the piston rod 212 out to be in close contact with the inner wall of the right end of the oil cylinder 213, the oil delivery hose 34 stops the oil delivery operation. At this time, the inner cavity of the oil cylinder 213 is full of oil.

[0055] When the door is closed, the push rod 211 indirectly pushes the molybdenum disulfide oil in the oil cylinder 213 to the left under the action of the push rod 211. Under the action of the leftward flow force of the molybdenum disulfide oil, the ball in the one-way valve 25 gradually seals the inlet of the one-way valve 25, so that the oil hose 234 and the inner cavity of the oil cylinder 213 are isolated.

[0056] In summary, under the action of the spring 216, the piston rod 212 is indirectly driven to draw the molybdenum disulfide oil from the oil tank 33 into the oil delivery hose 34, and then the oil delivery hose 34 guides the molybdenum disulfide oil into the pressure cylinder 213, thereby realizing the oil replenishment operation. This avoids the problem that the molybdenum disulfide oil cannot be replenished for lubrication after the bolt 11 has been used for a long time after the first lubrication. After the molybdenum disulfide oil in the oil tank 33 is used up, the oil inlet pipe 32 can be opened by turning the knob to seal the oil cap 31 to perform the replenishment operation, thereby improving the efficiency of lubrication replenishment of the bolt 11.
