Description

Technical Field

[0001] The utility model relates to the technical field of vehicle manufacturing and logistics transportation, and more specifically, to a trailer for multi-type police modular equipment. Background Art

[0002] In border areas, the vast territory and complex and changeable terrain together constitute a unique geographical picture. There are high mountains, deep canyons, vast deserts and vast grasslands. Each terrain challenges local police work in its own unique way. This geographical environment not only greatly increases the difficulty of patrolling and law enforcement for police officers, but also puts forward higher requirements for the rapid response and efficient handling capabilities of police work. Against this background, the traditional police equipment management method is particularly stretched. In traditional practices, the equipment of various police types is often stored in their respective police stations. Although this method meets the needs of daily patrols and law enforcement to a certain extent, it exposes many inconveniences in management. First of all, due to the decentralized storage of equipment, it is difficult to carry out unified scheduling and management. When a station is short of equipment or damaged, it is difficult to allocate and transport the required equipment from other stations in time, which undoubtedly affects the timeliness and effectiveness of police work. Secondly, the decentralized storage of equipment management method also increases the risk of loss and damage of equipment, especially in border areas. In such a harsh natural environment as the Xinjiang region, the equipment faces even more severe tests. Extreme weather conditions such as wind and rain erosion, sandstorms, and alternating high and low temperatures may cause damage to the equipment, and decentralized storage makes these equipment more susceptible to these factors. At the same time, due to the lack of unified management and maintenance, the risk of equipment loss also increases accordingly. What is more serious is that the border areas have heavy tasks, complex and changeable situations, and very limited police resources. In this case, a policeman often needs to assume a variety of different police duties. For example, public security police must manage social security and traffic management responsibilities. This diversified duty requirement makes the equipment required for different police types different. However, in an emergency, the decentralized storage equipment management method will seriously reduce the response speed and efficiency of police work, because police officers need to run between different sites to find and deploy the required equipment, which may not only delay the rescue time and cause unnecessary losses, but also endanger the lives of police officers. Therefore, it needs to be improved and optimized. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 7 As shown, the utility model provides a multi-type police modular equipment trailer, including a body 1, a mobile frame 6 is arranged on the top of the body 1, a pulling mechanism is arranged on the inner wall of the mobile frame 6, the pulling mechanism has four groups including a rotating rod 7 rotatably installed on the inner wall of the mobile frame 6, two connecting rods 8 are fixedly sleeved on the outer wall of the rotating rod 7, a placing frame 9 is rotatably installed on one side of the two connecting rods 8 close to each other, and two connecting rods 2 10 are hingedly installed on the outer wall of the placing frame 9, and the two connecting rods 2 10 are hinged to the inner wall of the mobile frame 6.

[0024] By operating the rotating rod 7 to rotate it, the rotation of the rotating rod 7 will drive the connecting rod 1 8 to move, and then drive the placement frame 9 to move. At the same time, the connecting rod 2 10 serves as a stabilizing structure to ensure the stability and safety of the placement frame 9 during movement. Compared with traditional devices, the design of this modular equipment trailer significantly improves the user's operating experience. In the past, the user may need to manually move or adjust the placement frame 9 located on the top of the vehicle body 1, which is not only time-consuming and labor-intensive, but also may increase the difficulty of operation and safety risks. Now, by setting a pulling mechanism, the user only needs to simply operate the rotating rod 7 to easily adjust the position of the placement frame 9. This operation method is not only convenient and fast, but also reduces the user's labor intensity and operation difficulty, and greatly improves the flexibility and practicality of the trailer.

[0025] The user can open the door panel by pushing the top of the door panel 19 upwards, and the telescopic rod 20 will extend as the door panel 19 is opened, ensuring that the door panel 19 can be smoothly opened to the desired angle. The user can slide the circular block 15 as needed to adjust the position of the partition 14, thereby separating goods in different areas. Before sliding the circular block 15, the user needs to press the pressing groove 16 to move the L-shaped block 17 to both sides and compress the spring 18 to release the locked state. After sliding the circular block 15 to the desired position, the pressing groove 16 is released, and the L-shaped block 17 automatically returns to the locked state under the action of the spring 18, fixing the circular block 15 and the partition 14 in the new position, and the height of the placement frame 9 is achieved by starting the motor 3. Adjustment, the output shaft of the motor 3 rotates to drive the bevel gear 1 4 to rotate, the bevel gear 1 4 is engaged with the bevel gear 2 5 to drive the bevel gear 2 5 to rotate, and the bevel gear 2 5 drives the movable frame 6 to rotate. According to the principle of threaded transmission, when the threaded rod 2 rotates, the movable frame 6 will move along the axial direction of the threaded rod 2, thereby adjusting the height of the placement frame 9 to prevent it from touching the items placed at the bottom. When the height of the placement frame 9 is too high and it is inconvenient for the user to take the items in the placement frame 9, at this time, the user pulls the pull rod 11 downward, and the pull rod 11 drives the rotating rod 7 to rotate. The rotation of the rotating rod 7 will drive the connecting rod 1 8 to move, thereby driving the placement frame 9 to move, so that the height of the placement frame 9 becomes lower, which is convenient for the user to take the items.

[0026] Among them, two rectangular bars 13 are fixedly installed on the top of the car body 1, and two round-shaped blocks 15 are slidably installed on the outer walls of the two rectangular bars 13. A partition 14 is fixedly installed on the side where the two round-shaped blocks 15 are close to each other. A snap mechanism is provided inside each round-shaped block 15. The snap mechanism includes a pressing groove 16 opened on the front side of the round-shaped block 15, and the pressing groove 16 runs through the round-shaped block 15. Two L-shaped blocks 17 are slidably installed on the inner wall of the pressing groove 16. The side where the two L-shaped blocks 17 are close to each other is elastically connected by a spring 18.

[0027] By setting up the buckle mechanism, when the position of the circular block 15 needs to be adjusted, the user only needs to press the pressing groove 16 to move the L-shaped block 17 to both sides and compress the spring 18. At this time, the L-shaped block no longer locks the rectangular bar 13, and the user can slide the circular block 15 to a new position. After releasing the pressing groove 16, the L-shaped block automatically returns to the locked state under the action of the spring 18, fixing the circular block 15 in the new position. The combined design of the rectangular bar, the circular block, the partition and the buckle mechanism realizes the convenience and safety of cargo separation, fixation and position adjustment.

[0028] Among them, a threaded rod 2 is rotatably installed on the top of the car body 1, the threaded rod 2 passes through the moving frame 6 and is threadedly connected to the moving frame 6, a bevel gear 2 5 is fixedly sleeved on the outer wall of the threaded rod 2, a motor protection shell 12 is fixedly installed on the top of the car body 1, a motor 3 is fixedly installed on the inner wall of the front side of the motor protection shell 12, a bevel gear 1 4 is fixedly sleeved on the output shaft of the motor 3, and the bevel gear 1 4 is meshed with the bevel gear 2 5.

[0029] By starting the motor 3, the output shaft of the motor 3 rotates to drive the bevel gear 1 4 to rotate, the bevel gear 1 4 engages with the bevel gear 2 5 to drive the bevel gear 2 5 to rotate, and the bevel gear 2 5 drives the threaded rod 2 to rotate. According to the principle of thread transmission, when the threaded rod 2 rotates, the movable frame 6 will move along the axial direction of the threaded rod 2.

[0030] Among them, a pull rod 11 is fixedly installed at the bottom of the placement frame 9, and there are four pull rods 11, which is the same as the number of the movable frame 6.

[0031] By providing the pull rod 11, the pull rod 11 provides the user with an intuitive and easy-to-operate power source. The user does not need to rely on additional equipment or tools, and can effectively move the entire placement frame 9 and the goods thereon by simply holding and pulling the pull rod 11.

[0032] A tooth groove 22 is formed on the top of the rectangular strip 13 , and the tooth groove 22 is matched with the two L-shaped blocks 17 .

[0033] By setting the tooth groove 22, the tooth groove 22 is a specific structure opened at the top of the rectangular bar 13, which perfectly adapts to the shape of the L-shaped block 17. When the L-shaped block 17 is inserted into the tooth groove 22, it can be accurately locked in the preset position to form a stable and strong connection, ensuring that the connection between the L-shaped block 17 and the tooth groove 22 is both accurate and strong, and effectively preventing loosening or misalignment.

The bottom ends of the four telescopic rods 20 are hingedly mounted with the outer wall of the vehicle body 1 .

[0037] The hinged design of the door panel 19 and the telescopic rod 20 makes the opening and closing operation of the door panel more convenient. When loading or unloading goods, the door panel can be quickly opened to form a wide opening for easy access of goods. Due to the existence of the telescopic rod 20, the door panel 19 can be adjusted in opening degree as needed, and the opening degree of the door panel can be changed by adjusting the length of the telescopic rod 20 to meet different loading requirements, making the device more adaptable and flexible.

[0038] The working principle and use process of this utility model:

[0039] The user can open the door panel by pushing the top of the door panel 19 upwards, and the telescopic rod 20 will extend as the door panel 19 is opened, ensuring that the door panel 19 can be smoothly opened to the desired angle. The user can slide the circular block 15 as needed to adjust the position of the partition 14, thereby separating goods in different areas. Before sliding the circular block 15, the user needs to press the pressing groove 16 to move the L-shaped block 17 to both sides and compress the spring 18 to release the locked state. After sliding the circular block 15 to the desired position, the pressing groove 16 is released, and the L-shaped block 17 automatically returns to the locked state under the action of the spring 18, fixing the circular block 15 and the partition 14 in the new position, and the height of the placement frame 9 is achieved by starting the motor 3. Adjustment, the output shaft of the motor 3 rotates to drive the bevel gear 1 4 to rotate, the bevel gear 1 4 is engaged with the bevel gear 2 5 to drive the bevel gear 2 5 to rotate, and the bevel gear 2 5 drives the movable frame 6 to rotate. According to the principle of threaded transmission, when the threaded rod 2 rotates, the movable frame 6 will move along the axial direction of the threaded rod 2, thereby adjusting the height of the placement frame 9 to prevent it from touching the items placed at the bottom. When the height of the placement frame 9 is too high and it is inconvenient for the user to take the items in the placement frame 9, at this time, the user pulls the pull rod 11 downward, and the pull rod 11 drives the rotating rod 7 to rotate. The rotation of the rotating rod 7 will drive the connecting rod 1 8 to move, thereby driving the placement frame 9 to move, so that the height of the placement frame 9 becomes lower, which is convenient for the user to take the items.
