Description

Technical Field

[0001] The present invention relates to the technical field of prison fences, in particular to an anti-escape fence reinforcement device for prisons. Background Art

[0002] With the continuous development of society and the increasing complexity of public security, prison security management faces increasingly stringent requirements. To prevent prisoner escapes and external vandalism, prisons typically use sturdy fencing systems as the first line of defense. These fencing systems, often composed of steel stanchions and transverse fencing panels, are highly resistant to impact and provide high security. However, with the continuous advancement of technology, some prisoners have begun to exploit structural flaws in the fencing to sabotage or escape. For example, they may weaken the fencing's stability and integrity by rocking it back and forth, repeatedly striking it, or exploiting its elasticity to amplify force.

[0003] While existing prison fences boast a certain degree of robustness in terms of material and structure, they remain inadequate for withstanding the constant and repeated back-and-forth swaying and impacts inflicted by prisoners. For one thing, traditional fences lack effective cushioning and shock absorption measures. This prolonged swaying can cause fatigue and loosening of support pillars, ultimately leading to structural damage or easy breaching. Furthermore, many existing fencing systems lack specialized cushioning devices, failing to absorb and disperse the impact loads inflicted by prisoners, increasing maintenance costs and posing safety risks. Summary of the Invention

[0004] (1) Technical problems solved In view of the deficiencies in the prior art, the present invention provides an anti-escape fence reinforcement device for prisons to solve the above problems.

[0005] (2) Technical solution To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an anti-escape fence reinforcement device for prisons, comprising a vertical fixing frame, a sliding card cavity being provided inside the vertical fixing frame, a sliding card frame that can slide back and forth being installed inside the sliding card cavity, two upper and lower fence support connecting rods being provided in front of the sliding card frame, the lower fence support connecting rod being installed at the bottom end of the front face of the sliding card frame, the upper fence support connecting rod being connected to a lifting and lowering adjustment member provided inside the sliding card frame, a first mounting groove being provided at the upper and lower ends of the sliding card cavity, and spring buffer members connected to the sliding card frame being installed inside the upper and lower first mounting grooves.

[0006] As the preferred technical solution of the present invention, the lifting and adjusting part specifically includes a driving screw, a screw sleeve and a rotating driving part. The driving screw is rotatably installed inside the sliding clamping frame. The screw sleeve is threadedly sleeved on the driving screw. A rotating driving part that drives the driving screw to rotate is installed at the bottom end of the sliding clamping frame. The upper fence support connecting rod is specifically connected to the front pipe wall of the screw sleeve.

[0007] As a preferred technical solution of the present invention, the rotating drive component includes a transmission gear, a driving gear, a mounting plate, a swivel and a rotary disk. The transmission gear is connected to the bottom end of the driving screw rod, the mounting plate is installed on the front side of the sliding clamping frame near the bottom end, the driving gear is installed on the mounting plate and meshes with the transmission gear, the swivel is connected to the driving gear, and the rotary disk is connected to the front end of the Susonghu swivel.

[0008] As a preferred technical solution of the present invention, the spring buffer includes a guide slide, a sliding sleeve and a buffer spring. The guide slide is installed inside the first mounting groove, the sliding sleeve is slidably sleeved on the guide slide, the guide slide is connected to the sliding clamping frame, and the buffer spring has two corresponding sliding sleeves on the front and rear ends of the guide slide and the center end is pressed tightly against the front and rear end surfaces of the sliding sleeve.

[0009] As a preferred technical solution of the present invention, second installation grooves are provided on both side walls of the sliding clamping cavity near the upper and lower ends, and a damping buffer member is installed inside each second installation groove to assist the sliding clamping frame in buffering operations.

[0010] As a preferred technical solution of the present invention, the damping buffer includes a buffer pad and a connecting slider. The connecting slider is slidably engaged in the second mounting groove and fixedly connected to the side wall of the sliding engaging frame. The buffer pad is installed on the front and rear end surfaces of the connecting slider.

[0011] As a preferred technical solution of the present invention, the front end of the fence support connecting rod is configured as a clamp capable of locking the prison fence support.

[0012] As a preferred technical solution of the present invention, a fixing seat is installed at the bottom end of the vertical fixing frame, and the fixing seat is fixed to the ground outside the fence through positioning bolts provided at four corner ends.

[0013] Compared with the prior art, the present invention provides an anti-escape fence reinforcement device for prisons, which has the following beneficial effects: This anti-escape fence reinforcement device effectively absorbs and cushions the force of the fence's back-and-forth swaying by providing a sliding engagement cavity within a vertical fixed frame, housing a sliding engagement frame that slides back and forth within it. This, combined with spring buffers at the top and bottom ends and damping buffers on both sides, effectively absorbs and cushions the force of the fence's back-and-forth swaying. The spring buffers utilize the elastic deformation of guide posts and buffer springs to ensure smooth movement of the sliding engagement frame in the intended direction while quickly and effectively absorbing impact loads applied by prisoners. This reduces concentrated force on the fence's support connecting rods and overall structure, preventing fatigue damage to the fence caused by prolonged swaying.

[0014] The damping buffer works together with the connecting slider through the buffer pad to further suppress the vibration and resonance of the sliding card frame, preventing the spring buffer from continuously following the shaking rhythm of the prisoner, improving the response sensitivity and durability of the buffer system, and effectively extending the service life of the fence reinforcement device.

[0015] Furthermore, the lifting and lowering mechanism, combined with the rotary drive, allows for precise height adjustment of the fence post connecting rod, allowing the reinforcement to adapt to fence posts of varying heights. This ensures the clamp securely locks onto the fence post, enhancing the stability and safety of the overall connection. The fixing base is securely attached to the ground outside the fence using positioning bolts, ensuring that the entire reinforcement does not shift when subjected to stress, further enhancing the overall structural strength.

[0016] In summary, this reinforcement device, through its organic combination of multiple buffering and adjustment mechanisms, effectively addresses the problem of prisoners attempting to break and escape by continuously rocking the fence back and forth. Its rational structure and excellent buffering properties significantly enhance the fence's resistance to damage and safety, ensuring the long-term stability of prison fences. This device not only enhances the fence's physical strength but also adapts to different fence environments through intelligent adjustment. It has broad application prospects and promotional value, providing a solid technical foundation for prison security management. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] See also Figure 1-6 A prison anti-escape fence reinforcement device includes a vertical fixing frame 1. A sliding clamping cavity 11 is provided within the fixing frame 1, within which a sliding clamping frame 2 is mounted, capable of sliding forward and backward. Two upper and lower fence post connecting rods 3 are located in front of the sliding clamping frame 2. The lower fence post connecting rod 3 is mounted at the bottom end of the front face of the sliding clamping frame 2, while the upper fence post connecting rod 3 is connected to a lifting and lowering adjustment member 4 provided within the sliding clamping frame 2.

[0023] The upper and lower ends of the sliding clamping cavity 11 are both provided with a first mounting groove 12, and a spring buffer 5 connected to the sliding clamping frame 2 is installed inside the first mounting groove 12. The spring buffer 5 includes a guide slide 51, a sliding sleeve 52 and a buffer spring 53. The guide slide 51 is installed inside the first mounting groove 12, and the sliding sleeve 52 is slidably sleeved on the guide slide 51, and the guide slide 51 is connected to the sliding clamping frame 2. There are two buffer springs 53, which are respectively slidably sleeved on the front and rear ends of the guide slide 51, and their respective center ends are pressed against the front and rear end surfaces of the sliding sleeve 52. The guide slide 51 ensures that the sliding sleeve 52 moves smoothly in the predetermined direction, and the buffer spring 53 absorbs the impact load during the sliding process through elastic deformation, thereby effectively absorbing the force of the prisoner's shaking back and forth, and effectively protecting the safety and stability of the fence.

[0024] The lifting and lowering adjustment member 4 specifically comprises a drive screw 41, a screw sleeve 42, and a rotary drive member 43. The drive screw 41 is rotatably mounted within the sliding clamping frame 2, and the screw sleeve 42 is threadedly mounted on the drive screw 41. The rotary drive member 43 is mounted at the bottom end of the sliding clamping frame 2 to rotate the drive screw 41. The upper fence post connecting rod 3 is connected to the pipe wall in front of the screw sleeve 42 at the top, allowing it to be adjusted according to the actual height of the prison fence side posts, so that the fence post connecting rod 3 can be positioned at the upper and lower ends of the fence posts when it is raised and lowered.

[0025] The rotary drive member 43 includes a transmission gear 431, a drive gear 432, a mounting plate 433, a swivel 434, and a rotary disk 435. The transmission gear 431 is connected to the bottom end of the drive screw 41. The mounting plate 433 is mounted on the front of the sliding clamping frame 2 near the bottom end. The drive gear 432 is mounted on the mounting plate 433 and meshes with the transmission gear 431. The swivel 434 is connected to the drive gear 432. The rotary disk 435 is connected to the front end of the swivel 434.

[0026] Second mounting slots 13 are provided on both sides of the sliding clamping cavity 11, near the upper and lower ends. Damping buffers 6 are installed within the second mounting slots 13 to assist in the buffering operation of the sliding clamping frame 2. The damping buffers 6 include a buffer block 61 and a connecting slider 62. The connecting slider 62 slides and engages within the second mounting slots 13 and is fixedly connected to the side walls of the sliding clamping frame 2. The buffer blocks 61 are mounted on the front and rear end surfaces of the connecting slider 62. The damping buffers 6 installed in the second mounting slots 13 provided on both sides of the sliding clamping cavity 11 further enhance the force of the sliding clamping frame 2 when absorbing the back and forth swaying of the fence, thereby preventing the spring buffer 5 from continuously swaying back and forth with the prisoner.

[0027] The front end of the fence support connecting rod 3 is provided with a clamp that can lock the prison fence support, which is used to stabilize the fence support and achieve effective connection. The reinforcement device can be added behind each support of the fence, thereby achieving an overall improvement in the safety and escape-proof performance of the fence.

[0028] A fixing base 7 is installed at the bottom end of the vertical fixing frame 1. The fixing base 7 is fixed to the ground outside the fence through positioning bolts 71 provided at four corner ends to ensure the stability of the overall structure.

[0029] The anti-escape fence reinforcement device operates as follows: First, the fixing base 7 is secured to the ground outside the prison fence using positioning bolts 71 at the four corners to ensure the overall structural stability. Then, depending on the actual height of the fence posts, the operator rotates the rotary disk 435, driving the rotary shaft 434 and the drive gear 432. The drive gear 432 engages with the transmission gear 431, driving the drive screw 41 to rotate. The drive screw 41, through its threaded action, drives the screw sleeve 42 up and down, adjusting the position of the upper fence post connecting rod 3. This, in turn, locks the clamps at the front ends of the upper and lower fence post connecting rods 3 to the upper and lower ends of the corresponding fence posts, achieving a secure connection.

[0030] After installation, the sliding clamping frame 2 can slide back and forth within the sliding clamping cavity 11. When a prisoner attempts to rock the fence back and forth, the rocking force is transmitted to the connected fence post connecting rod 3, which then transmits the force to the sliding clamping frame 2. At this point, the sliding clamping frame 2 slides in the predetermined direction within the sliding clamping cavity 11. The spring buffers 5 at the upper and lower ends begin to function. The guide slide 51 ensures that the sliding sleeve 52 moves smoothly in the predetermined direction. The buffer spring 53 absorbs the impact load through elastic deformation, effectively buffering the force generated by the prisoner's rocking.

[0031] At the same time, the damping buffers 6, located within the second mounting slots 13 on either side of the sliding engagement cavity 11, also absorb impact during movement, further reducing vibration during the swinging of the sliding engagement frame 2 and preventing the spring buffers 5 from continuously following the prisoner's swinging movements, thereby enhancing the overall stability and safety of the fence. The entire structural design effectively resists the prisoner's continuous back-and-forth swinging, ensuring that the fence is sturdy, secure, and difficult to damage or break through.
