Abstract
Description
Technical Field
[0001] This utility model relates to the field of fence technology, specifically to an arched fence with a locking structure. Background Technology
[0002] Arched fences, with their graceful curves and excellent structural mechanical properties, are widely used in courtyards, parks, municipal engineering, and isolation and protection applications. Traditional arched fences are mainly manufactured using either integral bending or segmented welding. The integral bending process requires sophisticated production equipment, necessitating large-radius bending machines to process large arcs, resulting in high production costs. Furthermore, the resulting arched components are bulky and highly susceptible to damage and deformation during transportation and storage, leading to extremely high logistics costs. In addition, integral structures require complete replacement after partial damage, resulting in substantial maintenance costs. Therefore, an arched fence with a locking mechanism is designed to address these issues. Utility Model Content

[0014] 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.
[0015] Please see Figure 1-5 This utility model provides a technical solution: an arched fence with a locking structure, comprising: a fence base 1, on which fences 2 are fixedly connected in an array on the inner upper surface of the fence base 1, and horizontal fences 3 are arranged between parallel fences 2. The horizontal fences 3 are welded and fixed to the parallel fences 2. At the corners, the fences 2 are fixedly connected to both sides of the fences 2, and the fences 2 at the corners are also connected to the fences 2 at the horizontal position through the connecting mechanism 4. The connecting mechanism 4 includes a left connecting rod 41, the right side of the left connecting rod 41 has a triangular docking groove 42, the right side of the left connecting rod 41 has a right connecting rod 43, the left side of the right connecting rod 43 is triangular and inserts into the docking groove 42, and the connection between the left connecting rod 41 and the right connecting rod 43 has a fixing hole 44, into which a pin 45 is inserted.
[0016] When using, such as Figure 1 As shown, the left and front sections form a horizontal fence 2, while the section of fence 2 that forms an arc at the junction of these two sections is a corner fence 2. Take a section of fence 2 that needs to be installed at the corner; its end is already fixed with the left connecting rod 41 of the connecting mechanism 4. Take another section of fence 2 in a horizontal position; its end is fixed with the right connecting rod 43. During installation, align the wedge-shaped triangular block on the left side of the right connecting rod 43 with the mating groove 42 on the left connecting rod 41, and gently push the right connecting rod 43 into the mating groove 42 of the left connecting rod 41 along the direction of the wedge-shaped slope. Due to the guiding effect of the inclined plane, the two will automatically correct their positions until the left end face of the right connecting rod 43 is completely in contact with the bottom of the docking groove 42. At this time, the axes of the two rods form the required predetermined angle, forming a smooth arched transition. Take out a pin 45, align its small diameter end with the aligned fixing hole 44, and gently tap the tail of the pin 45 with a rubber mallet or wooden mallet. Repeat this process until the next horizontal position of the fence 2 is reached. After connecting with another horizontal section of the fence 2, install it in the sleeve inside the fence base 1 and pour cement to fix it.
[0017] like Figure 1-5As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the fixing hole 44 and the pin 45 are generally conical, and the front end diameter of the fixing hole 44 and the pin 45 is larger than the rear end diameter.
[0018] Analysis of the above structure shows that it facilitates the insertion of the pin 45 into the fixing hole 44.
[0019] like Figure 1-5 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the four outer corners of the docking groove 42 and the four outer corners of the left end of the right connecting rod 43 are all arc-shaped.
[0020] Analysis of the above structure shows that when subjected to external impact, it can reduce the stress at the corners and reduce the probability of tearing.
[0021] like Figure 1-5 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, a slot is provided on the right side of the docking groove 42, and a protrusion is provided on the left side of the right connecting rod 43. The left protrusion of the right connecting rod 43 is inserted and connected to the slot on the right side of the docking groove 42.
[0022] Analysis of the above structure shows that when subjected to external impact, the left protrusion of the right connecting rod 43 will impact the slot on the right side of the mating groove 42, reducing the risk of tearing at the connection.
[0023] like Figure 1-5 As shown, this utility model embodiment provides an implementation method in which the pin 45 and the fixing hole 44 are interference fit.
[0024] Analysis of the above structure shows that the pin 45 and the fixing hole 44 are interference fit, which can increase friction and make the connection more secure.
[0025] like Figure 1-5 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the rear end of the pin 45 has an axially slit, making it hollow and expandable. A plastic tube 46 is inserted and connected inside the rear end hole of the pin 45. The interior of the plastic tube 46 is conical. A bolt 47 is provided at the rear end of the pin 45. An expansion sleeve 48 is wrapped around the rear end of the bolt 47. The expansion sleeve 48 is inserted and connected to the interior of the plastic tube 46. The end of the bolt 47 is connected to the interior of the pin 45 by threads.
[0026] Analysis of the above structure shows that after the pin 45 is inserted, the bolt 47 is inserted and tightened. The expansion sleeve 48 will be inserted into the plastic tube 46 and expand the plastic tube 46 outward, causing the rear end of the pin 45 to deform slightly, further enhancing the friction at the connection between the pin 45 and the fixing hole 44.
[0027] like Figure 1-5 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the left connecting rod 41, the right connecting rod 43, and the pin 45 are all made of carbon steel and their outer surfaces are coated with waterproof paint.
[0028] Analysis of the above structure shows that the left connecting rod 41, the right connecting rod 43, and the pin 45 are all made of carbon steel, which can ensure their strength, while the waterproof paint coating on the outer surface can reduce the probability of rust.
