Description
Technical Field
[0001] The utility model relates to the technical field of office accessory devices, in particular to a conveniently movable office environment gas purification device. Background Art
[0002] As we all know, a portable office environment gas purification device is an auxiliary device used inside an office to purify the air so as to better maintain a fresh environment inside the office. It has been widely used in the field of office.
[0003] Although the office environment gas purifier can be moved to a suitable position to play a better gas purification role by installing moving wheels at the bottom, the brakes equipped on the four rollers at the bottom of the office environment gas purifier are all independent and need to be locked in turn by stepping on them. During the stepping process, the other wheels are still in an active state, which can easily cause the main body of the device to move or rotate, affecting the use effect and poor convenience. Utility Model Content
[0004] The utility model mainly provides a conveniently movable office environment gas purification device which can synchronously lock all moving wheels to ensure the stability of the gas purifier.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a convenient and mobile gas purification device for office environment, including a purifier body, the bottom of the purifier body near the four corners are rotatably connected with a rotating gear, the bottom center of the rotating gear is fixedly connected with a connecting column, the bottom of the connecting column is fixedly connected with a wheel frame, and the inner surface walls of the wheel frame are rotatably connected with a moving wheel through a rotating shaft, and the bottom of the purifier body near the rotating gear is fixedly connected with a group of mounting frames, and the bottom of each group of the mounting frames is fixedly connected with an electric push rod, the telescopic end of the electric push rod is fixedly connected with a connecting plate, the outer surface of the connecting plate is fixedly connected with an engaging block, the outer surface of the engaging block is meshingly connected to the outer surface of the rotating gear, and the electric push rod is electrically connected to the control panel of the purifier body.
[0006] Preferably, telescopic rods are fixedly connected to the top of the wheel frame near the four corners, and conical sleeves are fixedly connected between the tops of the multiple telescopic rods. The conical sleeves are connected to the top of the wheel frame through the telescopic rods, so that they can move up and down within a certain stroke and will rotate with the wheel frame.
[0007] Preferably, the outer surface of the connecting column passes through the interior of the conical sleeve, and a plurality of springs are fixedly connected between the outer surfaces of the conical sleeve and the wheel frame. The plurality of springs are respectively arranged on the outside of a plurality of telescopic rods. The springs are mainly used to provide an upward thrust so that the conical sleeve is always in a high position when there is no pressure above it. When the conical sleeve is moved downward under pressure, the springs are squeezed and compressed at the same time.
[0008] Preferably, a plurality of connecting frames are fixedly connected at equal intervals to the bottom of the conical sleeve near the edge, and a connecting ring is fixedly connected between the bottom ends of the plurality of connecting frames. The connecting frames are mainly used to connect the connecting ring and the conical sleeve, so when the conical sleeve moves downward, the connecting frames will drive the connecting ring to move downward synchronously.
[0009] Preferably, a rubber pad is bonded to the bottom of the connecting ring, and the connecting frame is bent. After the connecting ring follows the conical sleeve to move to the lowest point, the connecting ring will be slightly higher than the bottom of the moving wheel and maintain a state of not contacting the ground. At this time, the rubber pad at the bottom of the connecting ring will be slightly lower than the bottom of the moving wheel, and will be deformed under the squeezing of the connecting ring and the ground, maintaining a large friction with the ground. In this state, the rubber pad is difficult to rotate. At this time, with the cooperation of the connecting frame, conical sleeve, telescopic rod and wheel frame, the stability of the moving wheel will be further improved.
[0010] Preferably, a wedge block is fixedly connected to the bottom of the engagement block, and the wedge block is L-shaped. When the engagement block moves in the direction of the rotating gear under the push of the electric push rod and the connecting plate, it will synchronously drive the wedge block to move.
[0011] Preferably, the right side of the wedge block is tilted upward, and the right side of the wedge block slides and fits with the top of the conical sleeve. When the wedge block moves in the direction of the rotating gear, its inclined surface will fit with the inclined surface of the conical sleeve. As the two get closer, the wedge block will generate an oblique downward force on the conical sleeve, causing the conical sleeve to move downward.
[0012] Compared with the prior art, the advantages and positive effects of the utility model are:
[0013] 1. In the utility model, after the electric push rod is started and the connecting plate drives the meshing block and the wedge block to approach the rotating gear, the meshing block and the rotating gear are meshed so that the wheel frame and the moving wheel cannot rotate. The wedge block squeezes the conical sleeve and generates a downward force to push the conical sleeve downward. At this time, the rubber pad can be in conflict with the ground under the action of the connecting frame and the connecting ring, so that the moving wheel cannot drive the purifier body to move, and then the device can stay stably in the specified position. The overall operation is convenient, and the function of convenient movement of the gas purification device in the office environment is retained, and the stability after movement is ensured, and the use effect is better.
[0014] 2. In the utility model, when it is necessary to move again, the electric push rod is started to cooperate with the connecting plate to drive the meshing block and the wedge block away from the rotating gear. After the meshing block and the rotating gear are released from the meshing state, the wedge block synchronously moves away from the conical sleeve. At this time, the spring rebound can drive the conical sleeve, the connecting frame and the rubber pad to move upward and off the ground. Then, under the action of the wheel frame and the moving wheels, the purifier body can be driven to move freely in the office. BRIEF DESCRIPTION OF THE DRAWINGS

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0022] See also Figure 1-Figure 4The utility model provides a technical solution: a convenient and mobile gas purification device for office environment, including a purifier body 1, the bottom of the purifier body 1 is rotatably connected to a rotating gear 3 near the four corners, the bottom center of the rotating gear 3 is fixedly connected to a connecting column 31, the bottom of the connecting column 31 is fixedly connected to a wheel frame 32, and the inner surface walls of the wheel frame 32 are rotatably connected to a moving wheel 33 through a rotating shaft. The bottom of the purifier body 1 near the rotating gear 3 is fixedly connected to a group of mounting frames 2, and the bottom of each group of mounting frames 2 is fixedly connected to an electric push rod 21, the telescopic end of the electric push rod 21 is fixedly connected to a connecting plate 22, the outer surface of the connecting plate 22 is fixedly connected to an engaging block 23, the outer surface of the engaging block 23 is meshed with the outer surface of the rotating gear 3, and the electric push rod 21 is electrically connected to the control panel of the purifier body 1.
[0023] like Figure 1-Figure 4 As shown, telescopic rods 41 are fixedly connected to the top of the wheel frame 32 near the four corners, and conical sleeves 4 are fixedly connected between the tops of the multiple telescopic rods 41. The conical sleeves 4 are connected to the top of the wheel frame 32 through the telescopic rods 41, so that they can move up and down within a certain stroke and will rotate with the wheel frame 32.
[0024] like Figure 1-Figure 4 As shown, the outer surface of the connecting column 31 passes through the interior of the conical sleeve 4, and a plurality of springs 42 are fixedly connected between the outer surfaces of the conical sleeve 4 and the wheel frame 32. The plurality of springs 42 are respectively sleeved on the outside of the plurality of telescopic rods 41. The springs 42 are mainly used to provide an upward thrust so that the conical sleeve 4 is always located at a high position when there is no pressure above it. When the conical sleeve 4 is pressed and moves downward, the springs 42 are squeezed and compressed at the same time.
[0025] like Figure 1-Figure 4 As shown, a plurality of connecting frames 43 are fixedly connected at equal intervals near the edge of the bottom of the conical sleeve 4, and a connecting ring 44 is fixedly connected between the bottom ends of the plurality of connecting frames 43. The connecting frames 43 are mainly used to connect the connecting ring 44 and the conical sleeve 4. Therefore, when the conical sleeve 4 moves downward, the connecting frames 43 will drive the connecting ring 44 to move downward synchronously.
[0026] like Figure 1-Figure 4 As shown, a rubber pad 45 is bonded to the bottom of the connecting ring 44, and the connecting frame 43 is bent. After the connecting ring 44 moves to the lowest point following the conical sleeve 4, the connecting ring 44 will be slightly higher than the bottom of the moving wheel 33 and maintain a state of not contacting the ground. At this time, the rubber pad 45 at the bottom of the connecting ring 44 will be slightly lower than the bottom of the moving wheel 33, and will be deformed under the squeezing of the connecting ring 44 and the ground, maintaining a large friction with the ground. In this state, the rubber pad 45 is difficult to rotate. At this time, with the cooperation of the connecting frame 43, the conical sleeve 4, the telescopic rod 41 and the wheel frame 32, the stability of the moving wheel 33 will be further improved.
[0027] like Figure 1-Figure 4 As shown, a wedge block 24 is fixedly connected to the bottom of the engagement block 23. The wedge block 24 is L-shaped. When the engagement block 23 moves toward the rotating gear 3 under the push of the electric push rod 21 and the connecting plate 22, it will synchronously drive the wedge block 24 to move.
[0028] like Figure 1-Figure 4 As shown, the right side of the wedge block 24 is tilted upward, and the right side of the wedge block 24 slides and fits with the top of the tapered sleeve 4. When the wedge block 24 moves toward the rotating gear 3, its inclined surface will fit with the inclined surface of the tapered sleeve 4. As the two get closer, the wedge block 24 will generate an oblique downward force on the tapered sleeve 4, causing the tapered sleeve 4 to move downward.
[0029] The method of use and working principle of the device: When moving the purifier body 1 in the office, just push the purifier body 1 to cooperate with the moving wheel 33 at the bottom. When the purifier body 1 moves to the specified position, start the four electric push rods 21 through the control panel. After the electric push rods 21 are started, they will push the meshing block 23 to move in the direction of the rotating gear 3 through the connecting plate 22. When the two are engaged, the freely rotating rotating gear 3 cannot rotate. At this time, the moving wheel 33 installed and connected at the bottom through the connecting column 31 and the wheel frame 32 cannot rotate at the same time and can only continue to roll. As the meshing block 23 moves, the wedge block 24 will synchronously move in the direction of the conical sleeve 4, and its inclined surface will fit with the inclined surface of the conical sleeve 4. As the two get closer, the wedge block 24 will generate an oblique downward force on the conical sleeve 4 and cause the conical sleeve 4 to move downward. When the conical sleeve 4 moves downward, it will squeeze The telescopic rod 41 and the spring 42 contract and drive the connecting ring 44 and the rubber pad 45 to move downward through the connecting frame 43. When the rubber pad 45 is tightly fitted to the ground, it cannot move due to the friction force, so that the device can stay stably in the specified position. The overall operation is convenient, and the function of convenient movement of the gas purification device in the office environment is retained. The stability after movement is also ensured, and the use effect is good. When it needs to be moved again, the electric push rod 21 is started to cooperate with the connecting plate 22 to drive the meshing block 23 and the wedge block 24 away from the rotating gear 3. After the meshing block 23 and the rotating gear 3 are released from the meshing state, the wedge block 24 synchronously moves away from the conical sleeve 4. At this time, the spring 42 rebounds to drive the conical sleeve 4, the connecting frame 43 and the rubber pad 45 to move upward and off the ground, and then the purifier body 1 can be driven to move freely in the office under the action of the wheel frame 32 and the moving wheel 33.
