The L-shaped lock hook is hooked onto the fixed lock hook seat, and the fixed rod is inserted into the interior of the fixed hole seat, securing the electricity meter box to the mounting bracket.

[0004] However, the current mounting bracket has the following problems: the mounting bracket is prone to errors during installation, resulting in the meter box not being in the center of the mounting bracket, which will cause the meter box to be unbalanced and affect the stability of the meter box, thereby causing the meter box to be installed loosely and easily affected by external forces and fall and be damaged. Therefore, we propose a meter box mounting bracket. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides an electric meter box mounting bracket, which solves the problem that the existing mounting bracket proposed in the above background technology is prone to errors during the installation process, resulting in the electric meter box not being in the center position of the mounting bracket, which will cause the electric meter box to be unbalanced and affect the stability of the electric meter box, thereby causing the electric meter box to be installed loosely and easily affected by external forces and fall and be damaged.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an electric meter box mounting bracket, comprising a mounting plate, a mounting frame fixed to the left and right sides of the back of the mounting plate, and also comprising a mounting device, a protective device, a lubricating device and a waterproof device; The two lever arm is pivotally connected to the bottom of the swing arm, and the two lever arm is pivotally connected to the bottom of the swing arm, and the two lever arm is pivotally connected to the bottom of the swing arm for swinging.

[0007] According to the above technical solution, the installation device also includes four rollers, two clamping belts, two friction wheels, two L-shaped scrapers, and a friction rod. A through-hole is opened on the back of the two pressure plates. The four rollers are rotatably installed above and below the inner walls of the through-holes of the two pressure plates. The two clamping belts are respectively connected to the outside of the two adjacent rollers. The two friction wheels are respectively fixed on the backs of the two lower rollers. The friction rod is fixed on the top back of the lower clamping plate, and the top surface of the friction rod is in contact with the outer wall of the friction wheel. The two L-shaped scrapers are respectively fixed on the positive and negative surfaces of the two pressure plates. The L-shaped scraper contacts the outer wall of the clamping belt. At the same time, when the pressure plate moves, the pressure plate drives the roller and the friction wheel to move. Under the action of the friction force between the friction wheel and the friction rod, the friction rod pushes the friction wheel to rotate, and the friction wheel drives the roller to rotate. The two rollers drive the clamping belt to rotate. The clamping belt increases the friction between the pressure plate and the meter box, thereby improving the stability of the pressure plate clamping the meter box. At the same time, the L-shaped scraper scrapes off foreign matter adhered to the surface of the clamping belt, thereby avoiding the problem of uneven stress distribution between the pressure plate and the meter box caused by foreign matter, which leads to mechanical damage to the pressure plate or the meter box.

[0008] The U-shaped shaft is fixed to the front of the mounting bracket, and the U-shaped shaft is fixed to the middle of the front of the mounting bracket. The two swinging plates are rotatably mounted on the outside of the U-shaped shaft, and a torsion spring is provided between the two swinging plates and the U-shaped shaft. The two arc plates are respectively fixed to one end of the two swinging plates away from the U-shaped shaft, and the two fixing columns are respectively fixed to the top of the two arc plates. The through-slot rod is slidably mounted on the top of the semi-arc plate, and through-slots are provided on the left and right sides of the top of the through-slot rod. The two fixing columns are both slidably mounted inside the through-slot of the through-slot rod. Before the mounting bracket is installed by bolts, the through-slot rod is pushed toward the back of the mounting bracket. At the same time, the two curved plates form a shield at the front position of the mounting frame, thereby expanding the protection range of the bolts.

[0009] The stabilizing arc plates are respectively fixed on the side of the stabilizing arc plates away from the mounting holes of the mounting bracket, and one end of the four L-shaped rods is respectively fixed on the inner wall of the two arc plates, and the other end of the four L-shaped rods is respectively slidably installed inside the four groove rods. When the two arc plates swing toward the sides of the U-shaped shaft rod, the arc plate drives the L-shaped rod to swing, and the L-shaped rod slides along the inside of the groove rod. The L-shaped rod pushes the groove rod to drive the stabilizing arc plate away from the mounting holes of the mounting bracket. When the arc plate is reset, the L-shaped rod pushes the groove rod to drive the stabilizing arc plate close to the mounting holes of the mounting bracket, and the stabilizing arc plate clamps and fixes the bolts, thereby improving the stability of the bolts after installation and avoiding the problem of the bolts loosening after installation.

[0010] According to the above technical solution, the lubrication device includes two lubricating oil tanks, four L-shaped pressing pieces, four contact plates, and two nozzle rings. The two lubricating oil tanks are respectively fixed on the front of the mounting frame, the four L-shaped pressing pieces are respectively fixed on the left and right sides of the two lubricating oil tanks, the four contact plates are respectively fixed on the front of the L-shaped pressing pieces, and the contact plates are located on the movement trajectory of the arc plate. The two nozzle rings are respectively embedded in the back of the mounting frame, and the two nozzle rings are respectively located at the two mounting holes of the mounting frame, and the two nozzle rings are connected to the two lubricating oil tanks through hoses. The L-shaped pressing piece is used to control the lubricating oil in the lubricating oil tank to be transferred to the nozzle ring through the hose for spraying. When the two arc plates swing to both sides of the U-shaped shaft, the arc plates push the contact plates to squeeze the L-shaped pressing piece. The L-shaped pressing piece controls the lubricating oil in the lubricating oil tank to be transferred to the nozzle ring through the hose for spraying. The sprayed lubricating oil will be sprinkled into the mounting hole of the mounting bracket. When the bolt is installed, the lubricating oil in the mounting hole of the mounting bracket will adhere to the bolt. The lubricating oil can form a protective film on the surface of the bolt to prevent air and moisture from contacting the metal surface, thereby reducing the risk of corrosion and oxidation of the bolt.

[0011] According to the above technical solution, the lubrication device also includes four folding bags, four L-shaped frames, and two jet rings. The four L-shaped frames are respectively fixed on the front sides of the two lubricating oil tanks, one end of the four folding bags is respectively fixed on the inner walls of the four L-shaped frames, and the other ends of the four folding bags are respectively fixed on the outer walls of the four resistance plates. The two jet rings are respectively fixed on the outer walls of the two nozzle rings, and the two jet rings are connected to the four folding bags by hoses. At the same time, when the resistance plate squeezes the L-shaped pressing piece, the resistance plate stretches the folding bag. When the arc plate is reset, it drives the resistance plate to reset, and the resistance plate squeezes the folding bag. The gas in the folding bag is transmitted to the jet ring through the hose and sprayed out. The sprayed gas will blow the lubricating oil in the mounting hole of the mounting frame, so that the lubricating oil can fully contact the bolt.

[0012] According to the above technical solution, the waterproof device includes a U-shaped frame, an inclined plate, and two triangular plates. The U-shaped frame is fixed between the tops of the two mounting frames, the inclined plate is fixed to the top of the U-shaped frame, and the two triangular plates are respectively fixed to the left and right sides of the top of the inclined plate. On rainy days, the inclined plate will direct rainwater to the wall, thereby avoiding the problem of rainwater falling directly on the mounting frame, causing the mounting frame to be corroded and damaged by rainwater, thereby improving the service life of the mounting frame; at the same time, the triangular plate will gather the rainwater falling on the inclined plate to the middle of the inclined plate, thereby avoiding the problem of rainwater overflowing at the mounting frame.

[0013] According to the above technical solution, the waterproof device also includes two rubber plates, two threaded plates, and two threaded rods. The two threaded plates are respectively fixed on the left and right sides of the bottom surface of the inclined plate. The two rubber plates penetrate and are slidably installed on the left and right sides of the back of the inclined plate. The two threaded rods are respectively rotatably installed on the front sides of the two rubber plates, and the outer sides of the two threaded rods are respectively connected to the inner threads of the two threaded plates. At the same time, after the mounting frame is installed, the threaded rod is rotated, and the threaded rod is restricted by the threaded plate. The threaded plate pushes the rubber plate against the wall, so that the rubber plate is close to the wall, thereby reducing the gap between the inclined plate and the wall, thereby further avoiding the problem of rainwater overflowing at the mounting frame.

[0014] The present invention provides an electric meter box mounting bracket. It has the following beneficial effects: (1) The present invention arranges the installation device so that the clamping plate, the bidirectional screw and the telescopic hinge rod cooperate to drive the pressure plate to push the meter box toward the center of the installation plate, thereby ensuring that the meter box is in the center of the installation plate during the installation process, avoiding the problem of unbalanced installation of the meter box, affecting the stability of the meter box, and causing the meter box to be installed loosely; at the same time, the pressure plate, the roller, the friction wheel, the roller and the clamping belt cooperate to increase the friction between the pressure plate and the meter box, thereby improving the stability of the pressure plate clamping the meter box, and at the same time, the L-shaped scraper scrapes off foreign matter adhered to the surface of the clamping belt, thereby avoiding the problem of uneven stress distribution between the pressure plate and the meter box caused by foreign matter, causing mechanical damage to the pressure plate or the meter box.

[0015] (2) The present invention provides a protective device so that the semi-arc plate shields the bolts at the mounting holes of the mounting frame, thereby preventing rainwater from falling directly on the bolts, which would cause the bolts to be easily damaged by moisture and corrosion. At the same time, the two arc plates shield the front of the mounting frame, thereby expanding the protection range of the bolts. The arc plate, L-shaped rod, groove rod, stable arc plate and mounting frame cooperate to drive the stable arc plate to clamp and fix the bolts, thereby improving the stability of the bolts after installation and avoiding the problem of the bolts becoming loose after installation.

[0016] (3) The present invention sets a lubricating device so that the arc plate and the contact plate cooperate to squeeze the L-shaped pressing piece. The L-shaped pressing piece controls the lubricating oil in the lubricating oil tank to be transmitted to the nozzle ring through a hose for spraying. The sprayed lubricating oil will be sprinkled in the mounting hole of the mounting frame. When the bolt is installed, the lubricating oil in the mounting hole of the mounting frame will adhere to the bolt. The lubricating oil can form a protective film on the surface of the bolt to prevent air and moisture from contacting the metal surface, thereby reducing the risk of corrosion and oxidation of the bolt; at the same time, the contact plate, the L-shaped pressing piece and the folding bag cooperate to make the contact plate squeeze the folding bag, and the gas in the folding bag is transmitted to the jet ring through a hose for spraying. The sprayed gas will blow the lubricating oil in the mounting hole of the mounting frame, so that the lubricating oil can fully contact the bolt.

[0017] (4) The present invention provides a waterproof device. On rainy days, the inclined plate will guide rainwater to the wall, thereby avoiding the problem of rainwater falling directly on the mounting frame, which will cause the mounting frame to be corroded and damaged by rainwater, thereby improving the service life of the mounting frame; at the same time, the triangular plate will gather the rainwater falling on the inclined plate to the middle of the inclined plate, thereby avoiding the problem of rainwater overflowing at the mounting frame; at the same time, after the mounting frame is installed, the threaded rod is rotated, and the threaded rod is restricted by the threaded plate, and the threaded plate pushes the rubber plate against the wall, so that the rubber plate is close to the wall, thereby reducing the gap between the inclined plate and the wall, thereby further avoiding the problem of rainwater overflowing at the mounting frame.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-9 , one embodiment of the present invention is: an electric meter box mounting bracket, comprising a mounting plate 1, a mounting frame 11 being fixed to the left and right sides of the back of the mounting plate 1, and further comprising a mounting device 2 and a protective device 3; Among them, the mounting device 2 includes two splints 21, a bidirectional screw 22, two telescopic hinged rods 23, and two pressure plates 24. A long slot is opened in the middle of the front side of the mounting plate 1, and the bidirectional screw 22 is rotatably mounted inside the long slot of the mounting plate 1. The two splints 21 are respectively threadedly connected to the upper and lower sides of the outside of the bidirectional screw 22, and the two pressure plates 24 are respectively slidably mounted on the top left and right sides of the lower splint 21. One end of the two telescopic hinged rods 23 is hinged to the left and right sides of the bottom of the upper splint 21, and the other ends of the two telescopic hinged rods 23 are hinged to the top of the two pressure plates 24. At the same time, when the two splints 21 move toward the center direction of the bidirectional screw 22, the upper splint 21 pushes the telescopic hinged rod 23 to drive the pressure plate 24 to move, and the pressure plate 24 pushes the electric meter box to move toward the center of the mounting plate 1, thereby ensuring that the electric meter box is in the center position of the mounting plate 1 during the installation process, avoiding the problem of unbalanced installation of the electric meter box, affecting the stability of the electric meter box, and causing the electric meter box to be installed loosely.

[0022] The mounting device 2 also includes four rollers 25, two clamping belts 26, two friction wheels 27, two L-shaped scrapers 28, and a friction rod 29. A through hole is opened on the back of the two pressure plates 24. The four rollers 25 are rotatably mounted above and below the inner walls of the through holes of the two pressure plates 24. The two clamping belts 26 are respectively connected to the outside of the two adjacent rollers 25. The two friction wheels 27 are respectively fixed to the back of the two lower rollers 25. The friction rod 29 is fixed to the top back of the lower clamping plate 21, and the top surface of the friction rod 29 is in contact with the outer wall of the friction wheel 27. At the same time, when the pressure plate 24 moves, the pressure plate 24 drives the rollers 25 and the friction wheels 27 to move. Under the action of the friction between the wheel 27 and the friction rod 29, the friction rod 29 pushes the friction wheel 27 to rotate, the friction wheel 27 drives the roller 25 to rotate, and the two rollers 25 drive the clamping belt 26 to rotate. The clamping belt 26 increases the friction between the pressure plate 24 and the meter box, thereby improving the stability of the pressure plate 24 clamping the meter box. The two L-shaped scrapers 28 are respectively fixed on the front of the two pressure plates 24, and the L-shaped scrapers 28 are in contact with the outer wall of the clamping belt 26. At the same time, the L-shaped scrapers 28 scrape off foreign matter adhered to the surface of the clamping belt 26, thereby avoiding the problem of uneven stress distribution between the pressure plate 24 and the meter box caused by foreign matter, resulting in mechanical damage to the pressure plate 24 or the meter box.

[0023] The protective device 3 includes a through-slot rod 31, two fixing columns 32, a semi-arc plate 33, two arc plates 34, a U-shaped shaft rod 35, and two swing plates 36. The semi-arc plate 33 is fixed to the top of the front of the mounting frame 11. Through the arrangement of the semi-arc plate 33, the semi-arc plate 33 forms a shield for the bolts at the mounting holes of the mounting frame 11, thereby preventing rainwater from falling directly on the bolts, causing the bolts to be easily damaged by moisture corrosion. The U-shaped shaft rod 35 is fixed to the middle of the front of the mounting frame 11, and the two swing plates 36 are respectively rotatably mounted on the outer sides of the U-shaped shaft rod 35. The two arc plates 34 are respectively fixed to one end of the two swing plates 36 away from the U-shaped shaft 35, and the two fixing columns 32 are respectively fixed to the top of the two arc plates 34. The through-slot rod 31 is slidably mounted on the top of the semi-arc plate 33, and through-slots are provided on the left and right sides of the top of the through-slot rod 31. The two fixing columns 32 are both slidably mounted inside the through-slot of the through-slot rod 31. At the same time, the two arc plates 34 form a shield at the front position of the mounting frame 11, thereby expanding the protection range of the bolts.

[0024] The protective device 3 also includes four L-shaped rods 37, four stabilizing arc plates 38, and four groove rods 39. The four stabilizing arc plates 38 are respectively slidably installed on the front side of the mounting frame 11. Two stabilizing arc plates 38 form a group. A group of stabilizing arc plates 38 are all located at the mounting holes of the mounting frame 11. The four groove rods 39 are respectively fixed on the side of the stabilizing arc plates 38 away from the mounting holes of the mounting frame 11. One end of the four L-shaped rods 37 is respectively fixed on the inner wall of the two arc plates 34, and the other end of the four L-shaped rods 37 is respectively slidably installed inside the four groove rods 39. When the arc plate 34 is reset, the L-shaped rod 37 pushes the groove rod 39 to drive the stabilizing arc plate 38 close to the mounting hole of the mounting frame 11. The stabilizing arc plate 38 clamps and fixes the bolts, thereby improving the stability of the bolts after installation and avoiding the problem of the bolts loosening after installation.

[0025] When in use, fix the mounting frame 11 to the wall or distribution cabinet with bolts, place the meter box on the lower clamping plate 21, rotate the bidirectional screw 22, and the bidirectional screw 22 drives the two clamping plates 21 to move toward the center of the bidirectional screw 22, so that the two clamping plates 21 clamp and fix the meter box, thereby realizing the installation operation of the meter box. At the same time, when the two clamping plates 21 move toward the center of the bidirectional screw 22, the upper clamping plate 21 pushes the telescopic hinge rod 23 to drive the pressing plate 24 to move along the top surface of the lower clamping plate 21 toward the center of the mounting plate 1, and the pressing plate 24 pushes the meter box toward the center of the mounting plate 1, thereby ensuring that the meter box is in the center position of the mounting plate 1 during the installation process, avoiding uneven installation of the meter box. The balance affects the stability of the meter box, resulting in the problem of loose installation of the meter box; at the same time, when the pressure plate 24 moves, the pressure plate 24 drives the roller 25 and the friction wheel 27 to move with it, and under the action of the friction force between the friction wheel 27 and the friction rod 29, the friction rod 29 pushes the friction wheel 27 to rotate, and the friction wheel 27 drives the roller 25 to rotate, and the two rollers 25 drive the clamping belt 26 to rotate, and the clamping belt 26 increases the friction force between the pressure plate 24 and the meter box, thereby improving the stability of the pressure plate 24 clamping the meter box. At the same time, the L-shaped scraper 28 scrapes off foreign matter adhered to the surface of the clamping belt 26, thereby avoiding the problem of uneven stress distribution between the pressure plate 24 and the meter box caused by foreign matter, which leads to mechanical damage to the pressure plate 24 or the meter box.

[0026] When the bolts are installed on the mounting bracket 11, the slotted rod 31 is pushed to move toward the back side of the mounting bracket 11, and the fixing post 32 slides along the slot inside the slotted rod 31, and the slotted rod 31 pushes the fixing post 32 to drive the two curved plates 34 and the swing plate 36 to swing to the sides of the U-shaped shaft rod 35 around the U-shaped shaft rod 35. At this time, the two curved plates 34 do not form a blockage at the mounting hole of the mounting bracket 11, and the bolts are installed on the mounting bracket 11. When the slotted rod 31 is not pushed, the slotted rod 31 no longer applies force to the fixing post 32, and under the action of the torsion spring corresponding to the swing plate 36, the swing plate 36 drives the curved plate 34 to return to its original position, and the curved plate 34 is again blocked at the mounting hole of the mounting bracket 11. Through the setting of the semi-arc plate 33, the semi-arc plate 33 is aligned with the mounting hole of the mounting bracket 11 The bolts are shielded, thereby preventing rainwater from falling directly on the bolts, which would cause the bolts to be easily damaged by moisture corrosion. At the same time, the two curved plates 34 form a shield at the front position of the mounting bracket 11, thereby expanding the protection range of the bolts. When the two curved plates 34 swing to both sides of the U-shaped shaft rod 35, the curved plates 34 drive the L-shaped rod 37 to swing, and the L-shaped rod 37 slides along the inside of the groove rod 39. The L-shaped rod 37 pushes the groove rod 39 to drive the stabilizing curved plate 38 away from the mounting hole of the mounting bracket 11. When the curved plate 34 is reset, the L-shaped rod 37 pushes the groove rod 39 to drive the stabilizing curved plate 38 close to the mounting hole of the mounting bracket 11. The stabilizing curved plate 38 clamps and fixes the bolts, thereby improving the stability of the bolts after installation and avoiding the problem of the bolts becoming loose after installation.

[0027] See also Figure 1-9 , based on the above embodiment, another embodiment of the present invention further includes a lubricating device 4 and a waterproof device 5; The lubrication device 4 includes two lubricating oil tanks 41, four L-shaped pressing members 42, four contact plates 43, and two nozzle rings 44. The two lubricating oil tanks 41 are respectively fixed to the front of the mounting frame 11, and the four L-shaped pressing members 42 are respectively fixed to the left and right sides of the two lubricating oil tanks 41. The four contact plates 43 are respectively fixed to the front of the L-shaped pressing members 42. The contact plates 43 are located on the movement trajectory of the arc plates 34. When the two arc plates 34 swing to both sides of the U-shaped shaft 35, the arc plates 34 push the contact plates 43 to squeeze the L-shaped pressing members 42. The two nozzle rings 44 are respectively embedded in the back of the mounting frame 11, and the two nozzle rings 44 are respectively fixed to the left and right sides of the two lubricating oil tanks 41. They are respectively located at the two mounting holes of the mounting bracket 11, and the two nozzle rings 44 are connected to the two lubricating oil tanks 41 through hoses. The L-shaped pressing piece 42 is used to control the lubricating oil in the lubricating oil tank 41 to be transferred through the hose to the nozzle ring 44 for spraying. The L-shaped pressing piece 42 controls the lubricating oil in the lubricating oil tank 41 to be transferred through the hose to the nozzle ring 44 for spraying. The sprayed lubricating oil will be sprinkled into the mounting holes of the mounting bracket 11. When the bolts are installed, the lubricating oil in the mounting holes of the mounting bracket 11 will adhere to the bolts. The lubricating oil can form a protective film on the surface of the bolts to prevent air and moisture from contacting the metal surface, thereby reducing the risk of corrosion and oxidation of the bolts.

[0028] The lubricating device 4 also includes four folded bags 45, four L-shaped frames 46, and two jet rings 47. The four L-shaped frames 46 are respectively fixed on the front sides of the two lubricating oil tanks 41, one end of the four folded bags 45 is respectively fixed on the inner walls of the four L-shaped frames 46, and the other ends of the four folded bags 45 are respectively fixed on the outer walls of the four contact plates 43. At the same time, when the contact plate 43 squeezes the L-shaped pressing piece 42, the contact plate 43 stretches the folded bags 45. When the arc plate 34 is reset, it drives the contact plate 43 to reset, and the contact plate 43 squeezes the folded bags 45. The two jet rings 47 are respectively fixed on the outer walls of the two nozzle rings 44, and the two jet rings 47 are connected to the four folded bags 45 by a hose. The gas in the folded bags 45 is transmitted to the jet ring 47 through the hose and sprayed out. The sprayed gas will blow the lubricating oil in the mounting hole of the mounting frame 11, so that the lubricating oil can fully contact the bolt.

[0029] The waterproof device 5 includes a U-shaped frame 51, an inclined plate 52, and two triangular plates 53. The U-shaped frame 51 is fixed between the tops of the two mounting frames 11, and the inclined plate 52 is fixed on the top of the U-shaped frame 51. On rainy days, the inclined plate 52 will guide rainwater to the wall, thereby avoiding the problem of rainwater falling directly on the mounting frame 11, causing the mounting frame 11 to be corroded and damaged by rainwater, thereby improving the service life of the mounting frame 11. The two triangular plates 53 are respectively fixed on the left and right sides of the top of the inclined plate 52. At the same time, the triangular plates 53 will gather the rainwater falling on the inclined plate 52 to the middle of the inclined plate 52, thereby avoiding the problem of rainwater overflowing at the mounting frame 11.

[0030] The waterproof device 5 also includes two rubber plates 54, two threaded plates 55, and two threaded rods 56. The two threaded plates 55 are respectively fixed on the left and right sides of the bottom surface of the inclined plate 52. The two rubber plates 54 pass through and are slidably installed on the left and right sides of the back of the inclined plate 52. The two threaded rods 56 are respectively rotatably installed on the front sides of the two rubber plates 54, and the outer sides of the two threaded rods 56 are respectively connected to the inner threads of the two threaded plates 55. At the same time, after the mounting frame 11 is installed, the threaded rods 56 are rotated, and the threaded rods 56 are restricted by the threaded plates 55. The threaded plates 55 push the rubber plates 54 against the wall, so that the rubber plates 54 are close to the wall, thereby reducing the gap between the inclined plate 52 and the wall, thereby further avoiding the problem of rainwater overflowing at the mounting frame 11.

[0031] When in use, when the two curved plates 34 swing to both sides of the U-shaped shaft 35, the curved plates 34 push the contact plates 43 to squeeze the L-shaped pressing pieces 42. The L-shaped pressing pieces 42 control the lubricating oil in the lubricating oil tank 41 to be transmitted through the hose to the nozzle ring 44 for spraying. The sprayed lubricating oil will be sprinkled into the mounting hole of the mounting frame 11. When the bolt is installed, the lubricating oil in the mounting hole of the mounting frame 11 will adhere to the bolt. The lubricating oil can form a protective film on the surface of the bolt to prevent air and moisture from contacting the metal surface, thereby reducing the risk of corrosion and oxidation of the bolt; at the same time, when the contact plates 43 squeeze the L-shaped pressing pieces 42, the contact plates 43 stretch the folding bags 45. When the curved plates 34 are reset, the contact plates 43 will be driven to reset. The contact plates 43 squeeze the folding bags 45. The gas in the folding bags 45 is transmitted through the hose to the jet ring 47 for spraying. The sprayed gas will blow the lubricating oil in the mounting hole of the mounting frame 11, so that the lubricating oil can fully contact the bolt.

[0032] At the same time, on rainy days, the inclined plate 52 will guide rainwater to the wall, thereby avoiding the problem of rainwater falling directly on the mounting frame 11, causing the mounting frame 11 to be corroded and damaged by rainwater, thereby improving the service life of the mounting frame 11; at the same time, the triangular plate 53 will gather the rainwater falling on the inclined plate 52 to the middle part of the inclined plate 52, thereby avoiding the problem of rainwater overflowing on the mounting frame 11; at the same time, after the mounting frame 11 is installed, the threaded rod 56 is rotated, and the threaded rod 56 is restricted by the threaded plate 55, and the threaded plate 55 pushes the rubber plate 54 against the wall, so that the rubber plate 54 is close to the wall, thereby reducing the gap between the inclined plate 52 and the wall, thereby further avoiding the problem of rainwater overflowing on the mounting frame 11.

[0033] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
