Description

Technical Field

[0001] This utility model relates to the field of disinfection equipment technology, and in particular to a mobile disinfection vehicle equipped with a germicidal lamp holder. Background Technology

[0002] The mobile disinfection cart equipped with a germicidal lamp holder is a practical device that combines efficient disinfection with flexible mobility. Its professional germicidal lamp holder stably secures ultraviolet germicidal lamps and other disinfection light sources. By releasing ultraviolet light of specific wavelengths, it can quickly destroy the DNA structure of bacteria and viruses, achieving deep disinfection of air and object surfaces with a high sterilization rate, effectively reducing the risk of cross-infection. Meanwhile, the cart is equipped with flexible casters at the bottom, making it easy and effortless to move between living rooms and bedrooms, shops, offices, and hospital wards and corridors. No fixed installation is required; it can be moved wherever disinfection is needed, making disinfection work more convenient and efficient, and providing flexible and reliable hygiene protection for various spaces.

[0003] Existing mobile disinfection vehicles use manual latches to adjust the height of the germicidal lamps. To adjust, the latch is pulled outwards, the lamp holder is adjusted to the desired height, and the latch is inserted into the corresponding hole. However, the latch's fixation depends on pre-set holes, and height adjustment is limited to a fixed position between two adjacent holes, preventing continuous, stepless fine-tuning. Current technology uses sliding grooves on the frame, with the germicidal lamp holder passing through these grooves and secured to the frame by a rotating rod. To adjust the height, the rotating rod is loosened, allowing the lamp holder to slide up or down along the groove to the desired height. The lamp holder is then secured back to the frame by the rotating rod. However, the lamp holder's stability depends entirely on the tightness of the rotating rod, lacking a mechanical locking mechanism, increasing safety risks. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a mobile disinfection vehicle with a germicidal lamp holder, aiming to improve the problem that the stability of the lamp holder in the prior art is entirely determined by the tightness of the screw, without a mechanical locking structure to prevent it from increasing safety hazards.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 5 An embodiment of this utility model is provided: a mobile disinfection vehicle with a germicidal lamp bracket, including a base 1, an adjustment mechanism 2 installed on the top of the outer wall of the base 1, the adjustment mechanism 2 being used to adjust the height of the germicidal lamp, and a quick-release mechanism 3 fixedly connected to the top of the outer wall of the base 1, the quick-release mechanism 3 being used to quickly detach and install the adjustment mechanism 2.

[0034] The adjustment mechanism 2 includes a support column 201, which is installed on the top of the outer wall of the base 1. A lifting column 202 is slidably connected inside the support column 201. An installation groove 203 is provided at the front end of the upper middle part of the lifting column 202. A drive assembly 204 is installed at the bottom end of the support column 201.

[0035] The drive assembly 204 includes a motor 2041, model MSME102G1V. Its working principle is that when DC current is applied to the armature winding, the current is subjected to Ampere force in the magnetic field. Under the action of force, the armature winding drives the rotor to rotate. However, due to the cooperation of the commutator and brushes, the current direction in the winding will automatically reverse every time the rotor rotates half a revolution, ensuring that the rotor is continuously subjected to torque in the same direction and realizing continuous rotation. The motor 2041 is installed at the bottom end of the support column 201. The output end of the motor 2041 is fixedly connected to a worm 2042. A worm wheel 2043 is installed on the left side of the outer wall of the worm 2042. The right side of the outer wall of the worm 2042 is meshed with the left side of the outer wall of the worm wheel 2043. A threaded rod 2044 is fixedly connected to the middle part of the worm wheel 2043. The bottom end of the outer wall of the threaded rod 2044 is rotatably connected to the bottom end of the inner part of the support column 201. The outer wall of the threaded rod 2044 is threadedly connected to the lower inner wall of the lifting column 202.

[0036] Specifically, starting the motor 2041 causes the output end to drive the worm gear 2042 to rotate. Through the meshing of the worm gear 2042 and the worm wheel 2043, the worm wheel 2043 drives the threaded rod 2044 welded in the middle to rotate at the bottom end inside the support column 201. The rotation of the threaded rod 2044 allows the lifting column 202 to slide vertically inside the support column 201. The height of the germicidal lamp in the installation slot 203 can be adjusted by raising and lowering the lifting column 202 to adapt to the sterilization range requirements of different disinfection scenarios. The self-locking structure of the worm wheel 2043 and the worm gear 2042 achieves mechanical locking, reducing safety hazards.

[0037] Reference Figure 4 , Figure 6 and Figure 7 The quick-release mechanism 3 includes a fixing frame 301, which is fixedly connected to the top of the outer wall of the base 1. The top of the fixing frame 301 is provided with multiple sliding grooves 302. The interior of the sliding grooves 302 is slidably connected to the bottom of the outer wall of the support column 201. A fixing component 303 is installed in the middle of the fixing frame 301. A limiting component 304 is fixedly connected to the rear end of the fixing component 303.

[0038] The fixing component 303 includes a knob 3031, which is installed in the middle of the fixing frame 301. A rotating shaft 3032 is fixedly connected to the rear side of the outer wall of the knob 3031. The outer wall of the rotating shaft 3032 is rotatably connected to the inside of the fixing frame 301. A plurality of first helical gears 3033 are fixedly connected to the middle of the outer wall of the rotating shaft 3032. A second helical gear 3034 is installed on the left side of the outer wall of each of the plurality of first helical gears 3033. A transmission shaft 3035 is fixedly connected to the middle of the second helical gear 3034. A plurality of double gears 3036 are fixedly connected to the top of the outer wall of the transmission shaft 3035. A double rack 3037 is installed on the outer wall of each of the plurality of double gears 3036. The outer walls of the double gears 3036 and the outer walls of the double racks 3037 are meshed. A support frame 3038 is slidably connected inside the double rack 3037. The top of the outer wall of the support frame 3038 is fixedly connected to the top of the inner wall of the fixing frame 301.

[0039] The limiting component 304 includes a ratchet 3041, which is fixedly connected to the front end of the fixing component 303. The middle part of the ratchet 3041 is fixedly connected to the front end of the outer wall of the rotating shaft 3032. A pawl bracket 3042 is installed on the outer side of the ratchet 3041, and the rear end of the outer wall of the pawl bracket 3042 is rotatably connected to the rear side of the inner wall of the fixing frame 301.

[0040] Specifically, rotating the knob 3031 allows the shaft 3032 on the rear side of its outer wall to rotate inside the fixed frame 301, thereby driving the two first helical gears 3033 welded to the outer wall to rotate. Through the meshing of the first helical gear 3033 and the second helical gear 3034, the second helical gear 3034 drives the transmission shaft 3035 in the middle to rotate, thereby causing the two double gears 3036 at the top of the transmission shaft 3035 to rotate as well. Through the meshing of the double gears 3036 and the double rack 3037, the double rack 3037 is moved, moving one end of the double rack 3037 to the bottom of the support column 201, thus quickly fixing the adjustment mechanism 2. At the same time, the cooperation between the ratchet 3041 and the pawl holder 3042 can restrict the rotation of the shaft 3032 from reversing. When it is necessary to disassemble the adjustment mechanism 2, simply lift the pawl holder 3042 and rotate the knob 3031 in the opposite direction to quickly remove the adjustment mechanism 2.

[0041] Reference Figure 1 , Figure 2 and Figure 3 Multiple universal brackets 4 are fixedly connected to the bottom of the outer wall of the base 1. Each of the multiple universal brackets 4 is equipped with wheels 5. The top of the lifting column 202 is rotatably connected to a germicidal lamp tube 6. The outer wall of the germicidal lamp tube 6 is slidably connected to the inside of the mounting groove 203. Multiple support rods 7 are fixedly connected to the rear end of the top of the outer wall of the base 1. A crossbar 8 is fixedly connected to the top of the outer wall of the support rod 7.

[0042] Specifically, multiple universal brackets 4 are installed at the bottom of the base 1, each with wheels 5 inside, allowing the base 1 to move flexibly. A germicidal lamp 6 is installed at the top of the lifting column 202 and the two are rotatably connected. The germicidal lamp 6 can adjust the irradiation angle to expand the sterilization range. The germicidal lamp 6 can be rotated into the mounting slot 203. Multiple support rods 7 are provided at the rear end of the base 1, and a crossbar 8 is fixed at the top of them to enhance the functionality of the overall structure. The various components cooperate with each other to ensure both the ease of movement of the base 1 and the stable operation of the germicidal lamp 6 and the practicality of the overall structure.

[0043] Working principle: When the motor 2041 is started, its output end can drive the worm gear 2042 to rotate. Through the meshing of the worm gear 2042 and the worm wheel 2043, the worm wheel 2043 drives the threaded rod 2044 welded in the middle to rotate at the bottom end inside the support column 201. The rotation of the threaded rod 2044 can make the lifting column 202 slide vertically inside the support column 201. The height of the germicidal lamp in the installation slot 203 can be adjusted by raising and lowering the lifting column 202 to adapt to the sterilization range requirements of different disinfection scenarios. The self-locking structure of the worm wheel 2043 and the worm gear 2042 achieves mechanical locking, reducing safety hazards.

[0044] Rotating the knob 3031 allows the shaft 3032 on the rear side of its outer wall to rotate inside the fixed frame 301, thereby driving the two first helical gears 3033 welded to the outer wall to rotate. Through the meshing of the first helical gear 3033 and the second helical gear 3034, the second helical gear 3034 drives the transmission shaft 3035 in the middle to rotate, thereby causing the two double gears 3036 at the top of the transmission shaft 3035 to rotate as well. Through the meshing of the double gears 3036 and the double rack 3037, the double rack 3037 is moved, moving one end of the double rack 3037 to the bottom of the support column 201, thus quickly fixing the adjustment mechanism 2. At the same time, the cooperation between the ratchet 3041 and the pawl holder 3042 can restrict the rotation of the shaft 3032. When it is necessary to disassemble the adjustment mechanism 2, simply lift the pawl holder 3042 and rotate the knob 3031 in the opposite direction to quickly remove the adjustment mechanism 2.
