Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and in particular to a protective device for special-purpose vehicle operation. Background Technology

[0002] In the field of special-purpose vehicles, vehicles face various complex working conditions and environmental factors during operation, such as severe weather, dust pollution, and mechanical collisions. These can damage the key components of the vehicle and affect its normal operation and service life. In order to ensure the safety, reliability and stability of special-purpose vehicles during operation, the use of protective devices is particularly important. Among them, vehicle protective covers are a common protective device and are widely used in the protection of special-purpose vehicles.

[0003] Traditional vehicle protective covers mostly adopt a one-piece molding design. While this design can provide relatively complete protection to a certain extent, its large size brings many inconveniences to transportation and carrying. In actual use scenarios, special vehicles often need to move frequently between different work sites, and large protective covers may take up too much space during transportation, increasing transportation costs. At the same time, due to its size and weight limitations, it is also more laborious for personnel to carry and install the protective cover, resulting in low operating efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a protective device for special vehicle operation.

[0005] This utility model is achieved by the following technical solution: a protective device for special vehicle operation, including a protective cover one and a protective cover two. An assembly plug is fixedly connected to the surface of the protective cover one, a positioning seat is fixedly connected to the surface of the assembly plug, and a rod mechanism is fixedly connected to the upper surface of the positioning seat. An embedding groove is opened on the surface of both the assembly plug and the positioning seat, and a protective inner layer is provided on the inner wall of both the protective cover one and the protective cover two.

[0006] The insertion rod mechanism includes an installation cylinder, an extension spring is fixedly connected to the inner wall of the installation cylinder, a contact ring is fixedly connected to the bottom of the extension spring, a locking pin is fixedly connected to the lower surface of the contact ring, and a pull rod is fixedly connected to the upper surface of the contact ring.

[0007] The above technical solution features a modular design for quick assembly and disassembly, facilitating transportation and carrying. This avoids the problems of bulky and inconvenient-to-carry integrated protective covers, reduces the workload of assembly and disassembly, and improves efficiency.

[0008] As a further improvement to the above solution, the mounting cylinder is fixedly connected to the upper surface of the positioning seat, and the locking pin is adapted to the embedding groove.

[0009] As a further improvement to the above solution, the surfaces of the first and second protective covers are provided with aluminum film, and the material of the inner protective layer is high-density PP cotton.

[0010] Through the above technical solutions, the aluminum film provides additional protective functions and extends the service life of the protective cover. The high-density PP cotton inner protective layer is soft and comfortable, effectively protecting the surface of the special vehicle.

[0011] As a further improvement to the above solution, several reinforcing rods are fixedly connected to the surface of the protective cover, and the reinforcing rods are evenly distributed symmetrically around the center of the right end surface of the protective cover.

[0012] The above technical solutions improve the overall strength of the protective cover, prevent deformation or damage during use, enhance the durability of the protective cover, and adapt to various usage environments.

[0013] As a further improvement to the above solution, the surface of the second protective cover is provided with several limiting grooves, which are concentric with the reinforcing rod.

[0014] The reinforcing rod and the limiting groove are adapted to each other, and the positioning seat has a cavity inside, which is adapted to the assembly plug.

[0015] The above technical solutions improve the fitting accuracy between the assembly insert and the positioning seat.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model adopts a modular design, using the combination of assembly blocks and positioning seats to achieve quick assembly and disassembly. Personnel pull the rod to raise the contact ring and locking pin, compressing the telescopic spring and causing the locking pin to disengage from the insertion slot, thus easily inserting or separating the assembly block and positioning seat. This avoids the problems of large size and inconvenience of traditional one-piece molded protective covers, while reducing the amount of labor involved in assembly and disassembly, improving efficiency. The modular structure makes the protective cover more compact during transportation and storage, and can be quickly assembled into a complete protective cover when in use, improving portability and functionality. In addition, the protective inner layer made of aluminum film and high-density PP cotton further enhances the protective performance, ensuring that the surface of the special vehicle is protected from external environmental damage.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0026] Please combine Figure 1-5 The special vehicle operation protection device of this embodiment includes a protective cover 1 and a protective cover 2. An assembly plug 3 is fixedly connected to the surface of the protective cover 1. A positioning seat 4 is fixedly connected to the surface of the assembly plug 3. A plug rod mechanism 5 is fixedly connected to the upper surface of the positioning seat 4. An embedding groove 6 is opened on the surface of both the assembly plug 3 and the positioning seat 4. A protective inner layer 7 is provided on the inner wall of both the protective cover 1 and the protective cover 2.

[0027] The insertion mechanism 5 includes an installation cylinder 501. A telescopic spring 502 is fixedly connected to the inner wall of the installation cylinder 501. A contact ring 503 is fixedly connected to the bottom of the telescopic spring 502. A locking pin 504 is fixedly connected to the lower surface of the contact ring 503. A pull rod 505 is fixedly connected to the upper surface of the contact ring 503. The protective cover 1 and the protective cover 2 are connected by the cooperation of the assembly block 3 and the positioning seat 4. During assembly, the pull rod 505 is lifted, which drives the contact ring 503 and the locking pin 504 to rise, compressing the telescopic spring 502. After the assembly block 3 is inserted into the positioning seat 4, the pull rod 505 is released, the telescopic spring 502 returns to its original position, and the locking pin 504 descends and passes through the embedding groove 6 to fix the assembly block 3. During disassembly, the pull rod 505 is lifted again, so that the locking pin 504 disengages from the embedding groove 6, separating the assembly block 3 and the positioning seat 4.

[0028] The mounting cylinder 501 is fixedly connected to the upper surface of the positioning seat 4, and the locking pin 504 is adapted to the embedding groove 6. The locking pin 504 and the embedding groove 6 are adapted to ensure that the assembly plug 3 can be accurately locked under the action of the telescopic spring 502.

[0029] The surfaces of protective cover 1 and protective cover 2 are covered with aluminum film. The inner layer 7 is made of high-density PP cotton. The aluminum film provides waterproof and sun protection functions. The inner layer 7 is made of high-density PP cotton, which provides a soft lining and protects the surface of the special vehicle from scratches.

[0030] Several reinforcing rods 8 are fixedly connected to the surface of the protective cover 1. The reinforcing rods 8 are symmetrically and evenly distributed around the center of the right end surface of the protective cover 1. The fixed connection of the reinforcing rods 8 to the surface of the protective cover 1 increases the structural strength and stability of the protective cover.

[0031] The surface of the protective cover 2 has several limiting grooves 9, which are concentric with the reinforcing rod 8.

[0032] The reinforcing rod 8 and the limiting groove 9 are compatible. The positioning seat 4 has a cavity 10 inside, which is compatible with the assembly plug 3. The positioning seat 4 has a cavity 10 inside, which is compatible with the assembly plug 3, to ensure that the assembly plug 3 can be accurately inserted and fixed.

[0033] The implementation principle of the special vehicle operation protection device in this embodiment is as follows: During assembly, the operator first aligns the assembly plug 3 on the surface of the protective cover 1 with the positioning seat 4 on the surface of the protective cover 2. Before insertion, the operator holds the pull rod 505 in the plug mechanism 5 and lifts it upward. Since the pull rod 505 is fixedly connected to the contact ring 503, it will drive the contact ring 503 to rise, thereby compressing the telescopic spring 502 on the inner wall of the mounting cylinder 501. As the contact ring 503 rises, the locking pin 504 fixed on its lower surface will also move upward, thereby causing the locking pin 504 to disengage from the embedding groove 6 inside the positioning seat 4. At this time, the operator inserts the assembly plug 3 into the interior of the positioning seat 4. When the assembly plug 3 is fully installed, the embedding groove 6 on its surface coincides with the embedding groove 6 on the surface of the positioning seat 4. Then, the operator releases the pulling force on the pull rod 505. Under the reset action of the telescopic spring 502, the contact ring 503 and the locking pin 504 will descend, and the locking pin 504 will... The mounting blocks 3 and the positioning seat 4 are respectively inserted into the grooves 6, which fix the position of the mounting blocks 3, so that the protective cover 1 and the protective cover 2 are firmly assembled together. When disassembling, the personnel only need to pull the lever 505 again to disengage the locking pin 504 from the groove 6, and then the mounting blocks 3 and the positioning seat 4 can be easily separated to complete the disassembly of the protective cover 1 and the protective cover 2. In addition, the surfaces of the protective cover 1 and the protective cover 2 are provided with aluminum film, which can provide waterproof and sun protection functions. The inner protective layer 7 of the inner wall is made of high-density PP cotton material, which provides a soft lining for the surface of the special vehicle and effectively prevents scratches. At the same time, the reinforcing rod 8 on the surface of the protective cover 1 matches the limiting groove 9 on the surface of the protective cover 2, further enhancing the structural strength and stability of the protective cover. The cavity 10 opened inside the positioning seat 4 matches the mounting blocks 3, ensuring that the mounting blocks 3 can be accurately inserted and fixed, improving the assembly accuracy and reliability of the entire protective cover.

[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
