A rapid descent device for high-altitude training of police dogs

Abstract

This utility model relates to the technical field of police dog training equipment, and discloses a rapid descent device for high-altitude training of police dogs. It includes a base plate, a base, a column, and a buffer mechanism. The base is fixedly connected to the top of the base plate, and the column is slidably connected inside the base. The buffer mechanism is fixedly connected to the top of the base plate. The mechanism includes an outer plate, a plate, and a spring. The core of this utility model lies in the fact that the outer plate has a groove and a slot communicating with the groove. The plate is connected to a sliding shaft. By inserting a stop block into the slot, the sliding shaft displacement can be physically blocked, keeping the device in a hard landing fixed state. When the stop block is pulled out, the plate is compressed, causing the sliding shaft to slide and compressing the spring, achieving a soft landing buffer state. This utility model solves the problem that existing devices cannot flexibly switch between soft and hard landing modes, leading to easy injury to police dogs or poor training adaptability. It also has excellent sealing and dustproof performance, extending the service life of the equipment.

Description

Technical Field

[0001] This utility model relates to the field of police dog training equipment technology, and in particular to a rapid descent device for high-altitude training of police dogs. Background Technology

[0002] In the police dog training system, high-altitude rappelling is a core subject, designed to develop the police dogs' courage, physical coordination, and adaptability to complex environments. To simulate real high-altitude working environments, specialized rappelling landing devices are typically used to assist the police dogs in descending from heights to the ground.

[0003] However, existing police dog rappelling landing devices are typically structurally fixed and lack effective cushioning and energy absorption designs. When a police dog descends rapidly from a height and lands on the device surface, the enormous impact directly affects the dog's limb joints. Prolonged, high-intensity, rigid landings can easily lead to bone damage or joint diseases, shortening the dog's service life. While some devices use entirely soft materials to protect the dog, this prevents them from simulating real hard ground environments, resulting in insufficient adaptability for the dogs when facing hard surfaces in combat. In other words, current technology struggles to simultaneously meet the needs of both "protective training" and "combat-ready training" within a single device.

[0004] Therefore, this utility model proposes a rapid descent device for high-altitude training of police dogs to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the fact that existing police dog rappelling landing devices generally lack an adjustable buffer mechanism, which makes it impossible to flexibly switch between soft and hard landing modes during training, easily causing joint damage to police dogs and failing to meet the needs of actual combat simulation, and that the height adjustment mechanism is susceptible to environmental corrosion when used outdoors, resulting in low reliability, this utility model aims to provide a police dog high-altitude training rappelling device with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a rapid descent device for high-altitude training of police dogs, comprising: a base plate, a base fixedly connected above the base plate, a column slidably connected inside the base, a buffer mechanism fixedly connected above the base plate, the buffer mechanism comprising an outer plate and a plate rotatably connected to the outer plate, a spring for buffering being provided between the plate and the outer plate; and a groove assembly, a sliding shaft, a slot, and a stop block.

[0007] The outer panel has a groove assembly on its inner wall, which includes a sliding groove. The outer wall of the outer panel also has a sliding shaft that slides within the sliding groove. The outer panel also has a slot communicating with the sliding groove and a stop block that cooperates with the slot.

[0008] Furthermore, the plate, the sliding shaft, and the stop block are combined through a specific positional engagement relationship: when the plate is not under pressure, the stop block is aligned with and inserted into the slot to a preset position, and the stop block is located below the sliding shaft to prevent the sliding shaft from displacing, thus fixing the plate in a fixed state; when the stop block disengages from the slot, the plate is under pressure, causing the sliding shaft to slide within the groove and compress the spring, thus placing the plate in a buffered state.

[0009] Preferably, the groove assembly further includes a circular groove formed in the outer plate, and the plate is fixedly connected to a limiting post. When the plate is pressed, the limiting post slides in the circular groove, and the circular groove provides displacement space for the limiting post.

[0010] Preferably, the spring is sleeved on the limiting post, with one end of the spring abutting against the plate and the other end abutting against the outer plate.

[0011] Preferably, the column body has a spiral pattern, the base has multiple positioning threads, and a fixing bolt is also included. The fixing bolt is screwed into the positioning threads and cooperates with the spiral pattern to fix the column body at different heights on the base.

[0012] Preferably, the base has a groove on its upper surface and also includes a sealing mechanism, which includes a sealing ring placed in the groove.

[0013] Preferably, the sealing mechanism further includes a semi-circular cover and a protrusion fixedly connected to the semi-circular cover. The base has an inverted T-shaped fixing groove. The protrusion is aligned with the fixing groove and slides into the final fixing point of the fixing groove to fix the sealing ring and seal the height adjustment points of the base and the column.

[0014] Preferably, when the protrusion reaches the preset position of the fixing groove, it slides into the final fixing point of the fixing groove under the action of gravity.

[0015] Preferably, the base plate provides support, and the base is fixedly connected above the base plate.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model, by setting a buffer mechanism above the base plate, utilizes the sliding groove inside the outer plate in conjunction with the sliding shaft on the plate, and combines the insertion and removal operation of the stop block, to solve the problem of existing police dog training devices having a single function and being unable to adapt to the needs of different training stages. It achieves the technical effect of flexibly switching between "soft landing" and "hard landing" modes. In soft landing mode, the spring can effectively absorb impact force and protect the police dog's joints, suitable for buffering after initial training or high-intensity training; in hard landing mode, the stop block physically locks the plate displacement, simulating a real hard ground, suitable for combat simulation training.

[0018] 2. This utility model solves the problem of outdoor training device lifting and adjusting mechanisms easily jamming or being damaged by dust and rainwater intrusion by setting a sealing mechanism on the top of the base. This is achieved through a sealing ring in the groove, a semi-circular cover with protrusions, and an inverted T-shaped fixing groove on the base. This results in excellent sealing and dustproof performance. Simultaneously, the structure utilizes the self-locking characteristic of the protrusions sliding into the bottom of the fixing groove under gravity, enabling convenient quick disassembly and maintenance without tools.

[0019] 3. This utility model solves the problems of inconvenient height adjustment or unstable fixation of traditional devices by using the spiral pattern and positioning thread between the column and the base, combined with the locking of the fixing bolts. It achieves the technical effect of being able to achieve precise height adjustment at multiple levels and stable locking according to the size of the police dog and the needs of the training subjects.

[0030] 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.

[0031] Example:

[0032] Reference Figures 1 to 5 This utility model provides a rapid descent device for high-altitude training of police dogs, which aims to solve the problems of existing training devices being unable to simultaneously accommodate soft landing buffering and hard landing fixed training modes, as well as the poor sealing performance of the height adjustment area leading to easy damage to the equipment.

[0033] like Figure 1 and Figure 2 As shown, the device includes a base plate 1 and a base 2 fixedly connected to the base plate 1. The base plate 1 serves as the basic load-bearing component of the entire device, providing a stable mounting surface for other mechanisms. The base 2 is vertically fixed to the base plate 1, and its interior is hollow to form a receiving space. A column 3 is slidably connected inside the base 2. The column 3 can move vertically up and down relative to the base 2, thereby adjusting its height according to training needs and providing training scenarios of different heights for police dogs.

[0034] A buffer mechanism 4 is also fixedly connected above the base plate 1. The buffer mechanism 4 is located on one side of the base plate 1 and is used to provide a landing platform for the police dog. The buffer mechanism 4 is mainly composed of an outer plate 41 and a plate 44. The outer plate 41 is fixedly connected to the base plate 1, and the plate 44 serves as the direct force-bearing surface. It is installed on the outer plate 41 through a specific movable connection method, so that the plate 44 can generate action feedback when under pressure, thereby cooperating with the internal components to achieve the function of buffering or fixed support.

[0035] Reference Figure 2 and Figure 3The inner wall of the outer plate 41 in the buffer mechanism 4 is provided with a groove assembly 48, which specifically includes a sliding groove 481 and a circular groove 482. Both the sliding groove 481 and the circular groove 482 are located inside the side wall of the outer plate 41 to provide a guide trajectory. The plate 44 is rotatably connected to the outer plate 41, and a sliding shaft 47 is fixedly connected to the outer wall of the plate 44. At the same time, a limiting post 45 is also fixedly connected to the plate 44. In the assembled state, the sliding shaft 47 slides in the sliding groove 481, and the limiting post 45 slides in the circular groove 482. The design of the circular groove 482 provides the necessary displacement space for the limiting post 45, so that the plate 44 is constrained by the dual trajectories of the sliding groove 481 and the circular groove 482 during movement, ensuring the stability of the movement.

[0036] A spring 46 is installed between the outer plate 41 and the plate 44. The spring 46 is sleeved on the outer periphery of the limiting post 45, with one end abutting against the inner wall of the outer plate 41 and the other end abutting against the plate 44. When the plate 44 is subjected to the impact force of the police dog falling, the plate 44 will drive the sliding shaft 47 to slide in the sliding groove 481, and at the same time drive the limiting post 45 to move in the circular groove 482 and compress the spring 46. The elastic potential energy of the spring 46 is used to absorb the impact force, realizing the soft landing training mode.

[0037] The outer plate 41 also has a slot 42 that communicates with the slide groove 481, and is equipped with a stop block 43 that cooperates with the slot 42. When it is necessary to fix the plate 44, in the uncompressed state of the plate 44, the stop block 43 is aligned and inserted into the slot 42 to the preset position. At this time, the end of the stop block 43 extends into the path of the slide groove 481 and is located below the slide shaft 47. The stop block 43 forms a physical block on the slide shaft 47, effectively preventing the slide shaft 47 from moving downward, thereby locking the plate 44 and preventing it from compressing the spring 46, thus achieving a hard landing fixed support effect.

[0038] Reference Figure 4 An adjustment mechanism for height adjustment is provided between the base 2 and the column 3. The column 3 has one or more axially oriented spiral threads 53, or a series of adjustment holes, while the side wall of the base 2 has multiple vertically oriented positioning thread holes 52. The fixing bolt 51 can be screwed into the positioning threads 52 and engages with the spiral threads 53 inside the column 3. When a fixed height is required, the spiral threads 53 inside the column 3 are aligned with the positioning threads 52 on the base 2, and the fixing bolt 51 is tightened, thereby achieving a fixed connection between the column 3 and the base 2 at a preset height. This threaded engagement structure ensures that the column 3 will not slip when subjected to vertical loads, ensuring safety during training.

[0039] Reference Figure 5A sealing mechanism 5 is provided above the base 2. The sealing mechanism 5 includes an annular groove 54 formed on the top end face of the base 2, and a sealing ring 55 is tightly embedded in the groove 54. The sealing mechanism 5 is also equipped with a semi-circular cover 56 and a protrusion 57 fixedly connected to the bottom of the semi-circular cover 56. A corresponding inverted T-shaped fixing groove 58 is formed on the outer wall of the base 2. The semi-circular cover 56 covers the top of the base 2 and presses the sealing ring 55, achieving fixation through the cooperation of the protrusion 57 and the fixing groove 58. Specifically, the protrusion 57 slides into the vertical entrance section of the fixing groove 58, and then slides horizontally into the bottom slot of the fixing groove 58. Because the fixing groove 58 is inverted T-shaped and the bottom slot is low, the protrusion 57 slides in under gravity and remains at the final fixing point of the fixing groove 58, achieving self-locking and preventing detachment, thereby firmly pressing the semi-circular cover 56 onto the sealing ring 55, achieving excellent sealing and dustproof effect.

[0040] The implementation principle of this embodiment is as follows: When the height of the device needs to be adjusted, the operator loosens the fixing bolt 51, causing the column 3 to slide vertically within the base 2 to the desired height, aligning the spiral thread 53 inside the column 3 with the corresponding positioning thread 52 on the base 2. Then, the fixing bolt 51 is tightened to lock the height. At this time, to protect the adjustment gap, the sealing ring 55 is placed in the groove 54 at the top of the base 2, and the semi-circular cover 56 is placed on top, aligning the protrusion 57 with the inverted T-shaped fixing groove 58. The protrusion 57 slides into the bottom locking point of the fixing groove 58 under gravity, completing the sealing installation.

[0041] When conducting police dog rappelling training, either a soft landing or hard landing mode is selected based on the training objective. For a soft landing to protect the dog's joints, the operator removes the stop block 43 from the slot 42, leaving the plate 44 movable. When the dog lands on the plate 44, the plate is compressed, causing the sliding shaft 47 to slide downwards within the slide groove 481, simultaneously moving the limiting post 45 within the circular groove 482. During this process, the spring 46 is compressed, utilizing its elastic damping to absorb impact energy and achieve cushioning. For a hard landing to simulate a hard surface, the operator inserts the stop block 43 into the slot 42 to a preset position with the plate 44 uncompressed. The stop block 43 is positioned below the sliding path of the sliding shaft 47, physically blocking it. When the plate 44 is compressed, the sliding shaft 47 is held in place by the stop block 43 and cannot slide downwards, preventing the spring 46 from being compressed. This keeps the plate 44 in a fixed, rigid state, achieving hard landing training.
