Description

Technical Field

[0001] This utility model relates to the field of liquefied petroleum gas (LPG) cylinder technology, specifically a fixed bracket for LPG cylinders with pressure warning function. Background Technology

[0002] Liquefied petroleum gas (LPG), as a clean and efficient energy source, is widely used in various fields such as home cooking, the catering industry, and industrial production. Its storage and transportation mainly rely on LPG cylinders. As high-pressure containers, LPG cylinders typically store liquefied petroleum gas inside, with operating pressures generally between 0.5 and 1.6 MPa. In the event of leaks, spills, or abnormal pressure, they can easily cause fires, explosions, and other safety accidents, posing a serious threat to the lives and property of the public.

[0003] In practical use, the safety of liquefied petroleum gas (LPG) cylinders has always been a focus of public concern. Firstly, the stability of the cylinder's mounting is fundamental to ensuring safety. Currently, there are many types of LPG cylinder mounting brackets on the market, but most have simple structures and limited functions, making them inconvenient for securing LPG cylinders of different sizes and thus inconvenient to use.

[0004] Therefore, we urgently need to provide a liquefied gas cylinder fixing bracket with pressure warning function. Utility Model Content

[0005] The purpose of this utility model is to provide a liquefied gas cylinder fixing bracket with pressure warning function, so as to solve the problem mentioned in the background art that the existing device is inconvenient to fix liquefied gas cylinders of different specifications and is inconvenient to use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a liquefied gas cylinder fixing bracket with pressure warning function, comprising a base plate and uprights, wherein the uprights are fixedly installed on the top left and right sides of the base plate, and a fixing device is provided above the base plate, wherein the fixing device includes a clamping mechanism, a pressing mechanism and an adjusting mechanism.

[0007] The clamping mechanism is located on the top of the base plate, the pressing mechanism is located above the base plate, and the adjusting mechanism is located above the base plate.

[0008] The clamping mechanism includes a movable block, a connecting shaft, an arc-shaped clamping plate, a rotating block, a threaded rod, a limiting rod, a mounting block, an arc-shaped clamping plate, a support frame, a motor, a rotating shaft, and gears. The movable block is sleeved on the outside of the two left and right uprights. The connecting shaft is fixedly installed on the adjacent side of the two movable blocks. The arc-shaped clamping plate is fixedly installed between the two connecting shafts. There are two rotating blocks, with one end of each rotating block rotatably connected to the outside of the connecting shaft. The threaded rod is rotatably connected to the front of the left rotating block. The limiting rod is fixedly installed on the front of the right rotating block. There are two mounting blocks, with the left mounting block threadedly connected to the outside of the threaded rod and the right mounting block slidably connected to the outside of the limiting rod. The arc-shaped clamping plate is fixedly installed between the two mounting blocks. One end of the support frame is fixedly installed on the outside of the rotating block, and the other end is slidably connected to the outer wall of the mounting block. The motor is fixedly installed on the top of the rotating block. The rotating shaft is fixedly installed at the output end of the motor. The gears are fixedly installed on the outside of the rotating shaft and the threaded rod, and the two gears mesh with each other.

[0009] Preferably, the base plate is equipped with casters on the back, and the upper side door of the upright is equipped with a pressure sensor. The pressure sensor is electrically connected to the controller and the alarm. By connecting the pressure sensor hose to the cylinder valve, the pressure sensor can detect the internal pressure of the cylinder in real time and transmit the signal to the controller. The controller processes the pressure signal, and when the pressure exceeds the preset safety range, the controller controls the alarm to emit an audible and visual alarm signal.

[0010] Preferably, the two gears mesh with each other, and rubber pads are installed on the inner sides of the second and first arc-shaped clamps. When fixing the liquefied gas cylinder, the cylinder is placed on top of the base plate, and then the second arc-shaped clamp is flipped downwards and rotated around the connecting shaft to a horizontal position via the rotating block. Then, the motor is started to drive the rotating shaft to rotate, which, in conjunction with the meshing transmission of the two gears, drives the first threaded rod to rotate and connect with the threaded block, thereby bringing the second arc-shaped clamp close to the cylinder and clamping it securely. When it is necessary to remove the cylinder, the motor is reversed to move the second arc-shaped clamp away from the cylinder, and the second arc-shaped clamp is flipped upwards so that it is positioned above the cylinder, thus avoiding obstruction of the cylinder removal by the second arc-shaped clamp and facilitating the fixing and removal of the liquefied gas cylinder.

[0011] Preferably, the mounting block has a protrusion on its side, and the support frame has a groove at the connection with the mounting block. The groove is slidably connected to the inner wall of the protrusion. When the arc-shaped clamping plate moves, the support frame cooperates with the protrusion to limit the movement of the arc-shaped clamping plate.

[0012] Preferably, the clamping mechanism includes a bracket, a threaded rod II, a pressure plate, a fixed hook, and a movable hook. The bracket is fixedly installed on the outside of the support frame, the threaded rod II is threadedly connected to the inside of the upper end of the bracket, the pressure plate is fixedly installed at the bottom of the threaded rod II, the fixed hook is fixedly installed on the upper side of the upright, and the movable hook is rotatably connected to the left and right sides of the bracket.

[0013] Preferably, the adjusting mechanism includes a spring, a disc, a locking rod, and a pull rod. One end of the spring is fixedly installed on the inner wall of the movable block, the disc is fixedly installed on the other end of the spring, the locking rod is fixedly installed on the end of the disc away from the spring, and the pull rod is fixedly installed on the side of the disc away from the locking rod.

[0014] Preferably, the side of the upright has equally spaced slots, and the diameter of the slots is equal to the diameter of the clamping rod. By engaging the clamping rod with the slots at different positions, the height of the arc-shaped clamp can be adjusted, thereby facilitating the fixing of liquefied gas cylinders of different heights.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This LPG cylinder fixing bracket with pressure warning function, through the setting of a clamping mechanism, when fixing the LPG cylinder, places the cylinder on top of the base plate, then flips the arc-shaped clamping plate two downwards and rotates it to a horizontal position around the connecting shaft via a rotating block. Then, the motor is started to drive the rotating shaft to rotate, and with the meshing transmission of two gears, the threaded rod one rotates and connects with the threaded block, thereby bringing the arc-shaped clamping plate two close to the cylinder and clamping it in place. When it is necessary to remove the cylinder, the motor is reversed to move the arc-shaped clamping plate two away from the cylinder, and the arc-shaped clamping plate two is flipped upwards so that it is positioned above the cylinder, thus avoiding the arc-shaped clamping plate two obstructing the removal of the cylinder, and facilitating the fixing and removal of LPG cylinders of different specifications.

[0017] 2. The LPG cylinder fixing bracket with pressure warning function has an adjustment mechanism that allows for height adjustment of the arc-shaped clamp by engaging the lever with slots at different positions. This facilitates fixing LPG cylinders of different heights and improves the flexibility of the device. Attached Figure Description

[0024] 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.

[0025] Example 1:

[0026] Due to the inconvenience of using existing technologies to secure liquefied petroleum gas (LPG) cylinders of different sizes, please refer to [link / reference needed]. Figures 1-5 This embodiment provides a liquefied petroleum gas (LPG) cylinder fixing bracket with pressure warning function, which facilitates the fixing and removal of LPG cylinders of different specifications. The LPG cylinder fixing bracket with pressure warning function includes a base plate 1 and uprights 2. The uprights 2 are fixedly installed on the top left and right sides of the base plate 1. Casters 7 are installed on the back of the base plate 1. A pressure sensor 3 (PT500-35MPa) is installed on the upper side door of the uprights 2. The pressure sensor 3 is electrically connected to a controller and an alarm. By connecting the hose of the pressure sensor 3 to the cylinder valve, the pressure sensor 3 detects the internal pressure of the cylinder in real time and transmits the signal to the controller. The controller processes the pressure signal, and when the pressure exceeds a preset safety range, the controller controls the alarm to emit an audible and visual alarm signal. The controller model is UDC1200DIN, and the alarm model is KJT-LV105. A fixing device is provided above the base plate 1, which includes a clamping mechanism, a pressing mechanism, and an adjusting mechanism.

[0027] The clamping mechanism is located at the top of the base plate 1, the pressing mechanism is located above the base plate 1, and the adjusting mechanism is located above the base plate 1.

[0028] The clamping mechanism includes a movable block 401, a connecting shaft 402, an arc-shaped clamping plate 403, a rotating block 404, a threaded rod 405, a limiting rod 406, a mounting block 407, an arc-shaped clamping plate 408, a support frame 409, a motor 410, a rotating shaft 411, and a gear 412. The movable block 401 is sleeved on the outside of the two left and right uprights 2. The connecting shaft 402 is fixedly installed on the adjacent side of the two movable blocks 401. The arc-shaped clamping plate 403 is fixedly installed between the two connecting shafts 402. There are two rotating blocks 404, and one end of each rotating block 404 is rotatably connected to the outside of the connecting shaft 402. The threaded rod 405 rotates... Connected to the front of the left rotating block 404, the limiting rod 406 is fixedly installed on the front of the right rotating block 404, limiting the start-up of the arc-shaped clamping plate 408. There are two mounting blocks 407: the left mounting block 407 is threaded to the outside of the threaded rod 405, and the right mounting block 407 is slidably connected to the outside of the limiting rod 406. A protrusion is provided on the side of each mounting block 407, and a groove is provided at the connection between the support frame 409 and the mounting block 407, with the groove slidably connected to the inner wall of the protrusion. When the arc-shaped clamping plate 408 moves, the support frame 409, in cooperation with the protrusion, limits the movement of the arc-shaped clamping plate 408. 8 is fixedly installed between the left and right mounting blocks 407. One end of the support frame 409 is fixedly installed on the outside of the rotating block 404, and the other end is slidably connected to the outer wall of the mounting block 407. The motor 410 is fixedly installed on the top of the rotating block 404. The motor 410 is a YN60-6C model and has forward and reverse rotation functions. The rotating shaft 411 is fixedly installed on the output end of the motor 410. The gear 412 is fixedly installed on the outside of the rotating shaft 411 and the threaded rod 405. The two gears 412 mesh with each other. Rubber pads are installed on the inner sides of the arc-shaped clamping plate 408 and the arc-shaped clamping plate 403. When fixing the liquefied gas cylinder, the cylinder is placed on top of the base plate 1, and then... The second curved clamp 408 is tilted downwards and rotated to a horizontal position around the connecting shaft 402 via the rotating block 404. Then, the motor 410 is started to drive the rotating shaft 411 to rotate. With the meshing of two gears 412, the threaded rod 405 is driven to rotate and connect with the mounting block 407. This allows the second curved clamp 408 to come close to the gas cylinder and clamp and fix it. When it is necessary to remove the gas cylinder, the motor 410 is reversed to move the second curved clamp 408 away from the gas cylinder and tilt the second curved clamp 408 upwards so that the second curved clamp 408 is above the gas cylinder. This avoids the second curved clamp 408 obstructing the removal of the gas cylinder and facilitates the fixing and removal of the liquefied gas cylinder.

[0029] To prevent the LPG cylinders from jumping during transportation and to further improve the stability of the cylinder fixation, this device is also equipped with a clamping mechanism. The clamping mechanism includes a bracket 501, a threaded rod 502, a pressure plate 503, a fixed hook 504, and a movable hook 505. The bracket 501 is fixedly installed on the outside of the support frame 409. The threaded rod 502 is threadedly connected to the inside of the upper end of the bracket 501. By rotating the threaded rod 502 and the screwed connection with the bracket 501, the pressure plate 503 moves down to press against the upper end of the LPG cylinder, thereby preventing the LPG cylinder from jumping. The pressure plate 503 is fixedly installed at the bottom of the threaded rod 502. The fixed hook 504 is fixedly installed on the upper side of the upright 2. The movable hook 505 is rotatably connected to the left and right sides of the bracket 501.

[0030] Example 2:

[0031] Based on Example 1, please refer to Figures 1-5 To enable the fixing of liquefied petroleum gas cylinders of different heights and improve the flexibility of the device, an adjustment mechanism is also provided. The adjustment mechanism includes a spring 601, a disc 602, a locking rod 603, and a pull rod 604. One end of the spring 601 is fixedly installed on the inner wall of the movable block 401, the disc 602 is fixedly installed on the other end of the spring 601, and the locking rod 603 is fixedly installed on the end of the disc 602 away from the spring 601. The side of the upright rod 2 has equally spaced slots, and the diameter of the slots is equal to the diameter of the locking rod 603. By engaging the locking rod 603 with the slots at different positions, the height of the arc-shaped clamp 403 can be adjusted, thereby facilitating the fixing of liquefied petroleum gas cylinders of different heights. The pull rod 604 is fixedly installed on the side of the disc 602 away from the locking rod 603.

[0032] In use, tilt the device backward so that the caster 7 contacts the ground, and push the device to the desired position. Then place the liquefied gas cylinder on top of the base plate 1. Then rotate the movable hook 505 away from the fixed hook 504, and pull the pull rod 604 outward to drive the locking rod 603 out of the slot opened on the upright 2. At this time, the arc-shaped clamping plate 403 can be pushed up and down along the upright 2 to a suitable height. Then release the pull rod 604, and under the action of the spring 601, push the locking rod 603 to engage with the slot, fixing the position of the arc-shaped clamping plate 403. Then flip the arc-shaped clamping plate 408 downward and rotate it to a horizontal position around the connecting shaft 402 via the rotating block 404. Then start the motor 410 to drive the rotating shaft 411 to rotate, which, in conjunction with the meshing transmission of the two gears 412, drives the screw... The threaded rod 405 rotates and connects to the mounting block 407, thereby bringing the arc-shaped clamp 408 closer to the cylinder and clamping it in place. Then, the threaded rod 502 rotates to move the pressure plate 503 down and press it against the cylinder. Next, the hose of the pressure sensor 3 is connected to the cylinder valve. The pressure sensor 3 detects the internal pressure of the cylinder in real time and transmits the signal to the controller. The controller processes the pressure signal. When the pressure exceeds the preset safety range, the controller controls the alarm to issue an audible and visual alarm signal to remind the staff to deal with it in time. When it is necessary to remove the cylinder, the reverse motor 410 is reversed to move the arc-shaped clamp 408 away from the cylinder and flips the arc-shaped clamp 408 upward so that it is above the cylinder. Then, the arc-shaped clamp 408 can be removed.
