[0026] To facilitate understanding by those skilled in the art, Figure 1-6 , the technical solution of the utility model is further described in detail.

[0027] As attached Figure 1-6 As shown, the utility model is a fire extinguisher bracket for the driver's seat of a household car, which mainly includes a fixing device, a lifting device, a protection device, and a safety pin unlocking device.

[0028] As attached Figure 1 、 2 The fixing device shown includes a telescopic rod 28, a first connecting rod 5 and a second connecting rod 3. The telescopic rod 28 is provided with three and consists of a telescopic inner rod 4 and a telescopic outer rod 2. The telescopic inner rod 4 includes a main telescopic inner rod 41 and a secondary telescopic inner rod 42. The telescopic outer rod 2 includes a main telescopic outer rod 21 and a secondary telescopic outer rod 22. The end side of the main telescopic inner rod 41 and one end of the two secondary telescopic inner rods 42 are connected to the first connecting rod 5. The other ends of the main telescopic inner rod 41 and the secondary telescopic inner rod 42 are provided with external threads 15, and correspond one-to-one with the main telescopic outer rod 21 and the secondary telescopic outer rod 22 with internal threads 16 at one end. The length of the entire telescopic rod 28 can be adjusted to fix the entire bracket in the storage compartment of the driver's door of the car. The length of the telescopic rod is adjusted by the external threads 15 and the internal threads 16 to adapt to the different designs of the side walls of the storage compartments of the driver's door of different cars.

[0029] The main telescopic outer rod 21 is slidably connected to the second connecting rod 3, and the second connecting rod 3 is slidably connected to the two secondary telescopic outer rods 22. The three telescopic rods 28 are connected to each other through the second connecting rod 3 to enhance the stability of the fixing device. The unthreaded end of the telescopic outer rod 2 is provided with a rubber pad 1, and the first connecting rod 5 is covered with two sections of rubber sleeves 27. When the utility model is fixed in the storage compartment, the rubber pad 1 and the rubber sleeve 27 in contact with the inner wall of the storage compartment can play an anti-slip role and enhance the stability of the fixed structure. The rubber material is elastic and can absorb vibration, further increase the stability of the bracket, and protect the surface material of the storage compartment from being scratched. The main telescopic inner rod 41 has a larger diameter than the secondary telescopic inner rod 42, and the main telescopic outer rod 21 has a larger diameter than the secondary telescopic outer rod 22. A rolling bearing 14 is fixed on the end side of the main telescopic inner rod 41 connected to the first connecting rod 5.

[0030] As attached Figure 3 The lifting device shown includes a bearing seat 6 and a pillar 7 that can be adapted to a rolling bearing 14. The rolling bearing 14 can rotate freely. The bearing seat 6 is sleeved with the rolling bearing 14 and the lower end is fixed to the top of the pillar 7. A T-shaped rack groove 23 with a sealed bottom is provided on one side of the pillar 7. An I-shaped rack 13 is slidably provided in the rack groove 23. A tooth section is provided on one side of the rack 13, and there is no tooth for 2 cm at the upper end of this side. The rack 13 can slide up and down along the rack groove 23. An electric motor 10 is fixed to the bottom end of the pillar 7. The output shaft of the electric motor 10 is fixedly sleeved with a gear 9. The gear 9 is engaged with the teeth provided on the rack 13. When the motor 10 is started, the rack 13 can be driven to move upward along the rack groove 23 through the gear 9. The lifting height can be set in advance by the manufacturer through the motor.

[0031] Combined with attachment Figure 6 As shown, an electronic device box 8 is embedded in the bottom side of the pillar 7, and the electronic device box 8 includes a power supply 19, a smoke sensor unit 20, a controller unit 21, and a buzzer unit 22. The controller unit 21 is provided on one side of the smoke sensor unit 20 and is electrically connected. The controller unit 21 is electrically connected to the power supply 19 and the buzzer unit 22 respectively. The power supply 19 is electrically connected to the motor 10. The power supply 19 supplies power to the electronic components in the electronic device box 8 and the motor 10. When a car catches fire due to a car accident or other reasons and produces smoke, the smoke sensor unit 20 receives the smoke signal and transmits the signal to the controller unit 21. The controller unit 21 controls the buzzer unit 22 to emit an alarm sound, and at the same time controls the start power supply 19 to supply power to the motor 10, so that the motor 10 starts to rotate and output power. The power is transmitted to the rack 13 through the gear 9, causing the rack 13 to move upward.

[0032] As attached Figure 4As shown, the protection device includes a limiting collar 11 and a sleeve 12. The limiting collar 11 is provided on one side of the pillar 7 where a rack slot 23 is provided. Both ends of the limiting collar 11 are fixedly connected to the two side walls of the pillar 7. The limiting collar 11 is used to sleeve the fire extinguisher. Six vertically and evenly arranged anti-collision strips 24 are provided on the inner side of the limiting collar 11. The anti-collision strips are made of elastic material and can buffer the fire extinguisher 29 through the anti-collision strips. A sleeve concentrically arranged with the limiting collar 11 is fixed on one side of the rack 13. The sleeve 12 has an open top for fixing the fire extinguisher 29. The inner side of the sleeve 12 is provided with a shock-absorbing layer 25. The shock-absorbing layer 25 is made of elastic material and the inner side adaptably fits the fire extinguisher 29, which is used to generate a certain damping for the fire extinguisher 29 to prevent it from falling off easily. The outer diameter of the sleeve 12 is slightly smaller than the inner diameter of the limiting collar 11. When the rack 13 drives the sleeve 12 to rise, the sleeve 12 can pass through the center of the limiting collar 11, automatically raising the height of the fire extinguisher 29 and exposing the handle for the driver to use it conveniently.

[0033] As attached Figure 5 As shown, the safety pin unlocking device is mainly composed of an elastic rope 18 and a safety pin 17. An elastic rope 18 is fixed to one side of the top of the limiting collar 11. The elastic rope 18 is elastic. A safety pin 17 is provided at the other end of the elastic rope 18. A plug 26 is provided at one end of the safety pin 17. When the device is installed, the fire extinguisher 29 is placed in the sleeve 12, the original safety pin of the fire extinguisher 29 is pulled out, the safety pin 17 is inserted, and the safety pin 17 is inserted into the plug 26. The plug 26 is made of rubber and has a large friction coefficient. It can prevent the safety pin 17 from falling off due to the bumps of the car, and the safety pin 17 can be easily pulled out when taking the fire extinguisher 29.

[0034] The working principle of this utility model:

[0035] The fixing device is placed in the storage compartment, and the main telescopic outer rod 21 is rotated to extend the entire telescopic rod until both ends of the telescopic rod are clamped. Then, the auxiliary telescopic inner rod 22 is adjusted to fix the utility model in the vehicle door. Subsequently, the fire extinguisher 29 is placed in the sleeve 12. Due to the action of gravity, the sleeve 12 where the fire extinguisher 29 is placed will drive the rack 13 to move downward until the toothless section reaches the bottom of the rack slide groove 23. The gear 9 and the rack 13 are in meshing state. At this time, the lower end of the fire extinguisher 29 is placed in the sleeve 12, and the upper end of the fire extinguisher 29 is surrounded and protected by the limiting collar 11 to prevent the fire extinguisher 29 from sliding out of the sleeve 12. In addition, the upper end of the lifting device is connected to the bearing 14 through the bearing seat 6, so that the entire lifting device drives the protective device to rotate freely. Due to the action of gravity, the bottom of the sleeve 12 can always point to the ground, preventing the fire extinguisher 29 from falling off and injuring the driver when the car is overturned due to a car accident. When a fire occurs inside the car and smoke is generated, the smoke sensor unit 20 in the electronic device box 8 will transmit a signal to the controller unit 21. Then the controller unit 21 will send an alarm command to the buzzer unit 22, causing the buzzer to sound an alarm to remind or wake up the driver in a coma. At the same time, the controller unit 21 sends a power-on command to the power supply 19. The power supply 19 supplies power to the motor 10, and the motor 10 starts to output power. The power is transmitted to the rack 13 through the gear 9, driving the rack 13 and the sleeve 12 to move upward, and the fire extinguisher 29 moves upward accordingly. At the same time, the elastic rope 18 is continuously tightened. When the elastic force on the elastic rope 18 is greater than the friction force between the plug 26 and the safety pin 17, the safety pin 17 will be pulled out of the safety position of the fire extinguisher 29 by the elastic rope, making the fire extinguisher 29 usable. At this time, the driver only needs to pick up the fire extinguisher 29 with one hand and press the switch with his thumb to make the fire extinguisher 29 spray the fire extinguishing medium. It is convenient, fast and easy to operate.

[0036] Except for the technical features described in the specification, all other technical features are known technologies to those skilled in the art.

[0037] In the present invention, "up", "down", "left", "right", "front" and "back" are relative positions used to conveniently describe positional relationships, and therefore cannot be understood as absolute positions to limit the scope of protection.

[0038] The above content is merely an example and explanation of the structure of the present utility model. Technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the scope of protection of the present utility model.
