Description

Technical Field

[0001] This utility model relates to the field of fence design technology, specifically a conveniently assembled wall fence. Background Technology

[0002] With the acceleration of urbanization and the development of modern architectural concepts, the functional requirements of fences and walls, as an important part of the building envelope, are increasing. Traditional fixed fences generally adopt welding or integral casting processes. Although they perform well in terms of structural stability, they have significant drawbacks such as high transportation costs, long installation cycles, and poor spatial adaptability. According to statistics, the damage rate of integral fences in the logistics process is as high as 12%-15%, and the transportation space utilization rate of a standard 3-meter fence section is less than 40%, resulting in serious waste of resources.

[0003] In the existing technology, although the segmented fence proposed by patents such as CN2082028U has improved the convenience of transportation, it still has problems such as complex connection nodes and high requirements for on-site assembly precision. In particular, its hinge mechanism mostly adopts an external design, which makes key components susceptible to environmental corrosion and the average service life is less than 5 years.

[0004] In terms of construction efficiency, traditional fence installation requires 3-4 professional workers to complete, with an average time of about 45 minutes per linear meter. Existing quick-installation fences, due to insufficient component positioning accuracy, still require 20-30 minutes per linear meter for installation. At the same time, most detachable structures lack effective storage design, resulting in component scattering and loss rates as high as 18% during periods of inactivity. These technical bottlenecks severely restrict the promotion and application of prefabricated fences in temporary buildings, landscape projects, and other fields. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model proposes the following technical solution:

[0006] A conveniently assembled fence includes a base on which a main body is fixedly mounted. A left connecting rod is rotatably mounted at the end of the main body away from the base, and a right connecting rod is rotatably mounted at the end of the main body away from the base. The left and right connecting rods are respectively installed in different grooves on the main body. Multiple horizontal bars are rotatably mounted at the end of the main body near the base. The horizontal bars are arranged symmetrically on the base and are located in grooves on the main body.

[0007] Furthermore, the left connecting rod, right connecting rod, and crossbar are provided with multiple mounting slots, in which fence bars are movably installed. One end of the fence bar is provided with an upper end cap, and the end of the fence bar near the upper end cap is provided with a recessed slot. The recessed slot is used to fix the position of the fence bar on the left connecting rod and right connecting rod. The fence bar can also be installed in the mounting slot on the crossbar.

[0008] Furthermore, a right pressure block is slidably installed inside the left connecting rod, and a right bolt rod is rotatably installed on the right connecting rod. The right bolt rod and the right pressure block are connected by threads. A rotating block is rotatably installed at the end of the left connecting rod away from the base. The rotating block protrudes out of the outside of the right connecting rod. A protrusion is also provided at the end of the right connecting rod where the rotating block is located. The protrusion can be embedded in the right connecting rod on the adjacent base. A recessed circular groove is provided on the protrusion.

[0009] Furthermore, a left pressure block is slidably installed inside the left connecting rod, a locking groove is provided on the inner side of the end of the left connecting rod away from the base, a left bolt rod is threadedly installed on the end of the left connecting rod away from the base, the left bolt rod is rotatably connected to the left pressure block, and a top block is fixedly installed on the end of the left bolt rod inside the left connecting rod, the top block being made of hard rubber.

[0010] Furthermore, the main body is cross-shaped, and the four grooves on the cross shape of the main body are used to accommodate the extension parts of the device.

[0011] The advantages of this utility model compared with the prior art are: (1) This device can reduce the space required for storage or transportation by storing the rotatable left and right connecting rods in the groove on the base. At the same time, the separate design of the fence allows the device to be quickly assembled when needed. (2) This device can be quickly assembled when used by fitting the fence with the left and right connecting rods. In addition, the left and right connecting rods can be tightly connected by multiple fastening devices, which improves the installation efficiency. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] like Figure 1 , Figure 2 , Figure 8 , Figure 9 As shown, a conveniently assembled fence includes a base 101 with multiple bolt mounting holes. The base 101 is fixed to the ground with bolts during use. In locations requiring movement, a weight can be placed on the base 101 to hold it in place. A main body 102 is fixedly mounted on the base 101. The main body 102 is cross-shaped, with four grooves on the cross shape to accommodate the extension parts of the device. A reflective warning top is provided at the end of the main body 102 away from the base 101. The warning top can be replaced with different shapes according to customer needs, such as a sharp top or a top with special symbols, which can be welded onto the warning top or the main body 102.

[0025] like Figure 1 , Figure 2 , Figure 8 , Figure 9 As shown, a left connecting rod 201 is rotatably mounted on the end of the main body 102 away from the base 101, and a right connecting rod 202 is rotatably mounted on the end of the main body 102 away from the base 101. The left connecting rod 201 and the right connecting rod 202 are respectively installed in different grooves on the main body 102. A plurality of crossbars 103 are rotatably mounted on the end of the main body 102 near the base 101. The crossbars 103 are arranged in grooves on the main body 102 and are symmetrically arranged on the base 101.

[0026] As Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 10 shown, multiple mounting grooves are provided on the left connecting rod 201, the right connecting rod 202, and the cross bar 103. A railing 104 is movably installed in the mounting groove. An upper end cover 105 is provided at one end of the railing 104. L-shaped blocks are provided at the parts of the upper end cover 105 that contact the left connecting rod 201 and the right connecting rod 202 to stabilize the position of the railing 104 on the left connecting rod 201 and the right connecting rod 202. A recessed card slot is provided at one end of the railing 104 close to the upper end cover 105. The recessed card slot is used to fix the position of the railing 104 on the left connecting rod 201 and the right connecting rod 202. The railing 104 can also be installed in the mounting groove on the cross bar 103.

[0027] As Figures 1 to 7 shown, a right pressing block 204 is slidably installed in the left connecting rod 201. One side of the right pressing block 204 can fit into the recessed card slot on the railing 104. After the right bolt rod 205 fits into the recessed card slot, the position of the railing 104 is stuck on the right connecting rod 202. A right bolt rod 205 is rotatably installed on the right connecting rod 202. The right bolt rod 205 is threadedly connected to the right pressing block 204. A cross slot is provided at one end of the right bolt rod 205 outside the right connecting rod 202 to facilitate the user to drive the right bolt rod 205 to rotate with a cross screwdriver. The rotation of the right bolt rod 205 is used to drive the right pressing block 204 to slide in the right connecting rod 202. A rotating block 203 is rotatably installed at one end of the left connecting rod 201 away from the base 101. The rotating block 203 protrudes outside the right connecting rod 202. A return torsion spring is provided between the rotating block 203 and the right connecting rod 202. The function of the rotating block 203 is to be inserted into the left connecting rod 201 on the other side of the base 101 to connect two adjacent bases 101. The rotating block 203 is in the shape of the Chinese character 'eight' in the normal state. A convex block 209 is also provided at one end of the right connecting rod 202 where the rotating block 203 is provided. The convex block 209 can be inserted into the right connecting rod 202 on the adjacent base 101 to increase the rigidity when two adjacent bases 101 are connected. A recessed round slot is provided on the convex block 209.

[0028] As Figures 1 to 7As shown, a left pressure block 206 is slidably installed inside the left connecting rod 201. The function of the left pressure block 206 is the same as that of the right pressure block 204, both being designed to limit the position of the fence post 104. A locking groove is provided on the inner side of the end of the left connecting rod 201 away from the base 101, which can engage with the rotating block 203. A left bolt rod 207 is threadedly installed on the end of the left connecting rod 201 away from the base 101. A cross groove is provided on the end of the left bolt rod 207 outside the left connecting rod 201. The left bolt rod 207 is rotatably connected to the left pressure block 206. A top block 208 is fixedly installed at one end of the left bolt rod 207 inside the left connecting rod 201. The top block 208 is made of hard rubber and is used to press the rotating block 203 so that the rotating block 203 fits into the locking groove and can limit the position of the rotating block 203 to prevent the rotating block 203 from detaching from the left connecting rod 201. At the same time, the rotating block 203 can also fit into the recessed circular groove on the protrusion 209 to limit the position of the protrusion 209.

[0029] This device is for use when not in use. Figure 8 , Figure 9 In the state shown, the left connecting rod 201, right connecting rod 202, and crossbar 103 are retracted into the groove of the main body 102. This state facilitates the storage or transportation of the device. At the same time, the multiple fence bars 104 of the device can also be bundled together for storage or transportation. When the device is used in some flexible locations, the base 101 is usually pressed to the ground by a heavy object. When the device is used in some fixed locations, bolt posts are usually pre-embedded in the concrete according to the bolt holes on the base 101, and then the base 101 is fixed to the ground by bolt installation. Alternatively, expansion bolts can be used to replace the pre-embedded bolt posts.

[0030] After installing the base 101, the left connecting rod 201, right connecting rod 202, and crossbar 103 on the main body 102 can be unfolded by rotating the left connecting rod 201, right connecting rod 202, and crossbar 103 by 90 degrees. At the same time, adjacent bases 101 can be installed. After the adjacent bases 101 are unfolded, as... Figure 1 and Figure 2In the state shown, the left connecting rod 201 and right connecting rod 202 on the adjacent base 101 can be assembled. During assembly, first, the rotating block 203 needs to be manually pressed to retract it. Then, the retracted rotating block 203 is inserted into the adjacent right connecting rod 202, allowing it to enter. After releasing the pressure on the rotating block 203, it will rotate via the return torsion spring, thus allowing... The rotating block 203 enters the locking groove in the left connecting rod 201, allowing it to engage with the left connecting rod 201 and lock it in place. Simultaneously, as the rotating block 203 enters the left connecting rod 201, the protrusion 209 also enters it, allowing the protrusion 209 and the rotating block 203 to connect the left connecting rod 201 and the right connecting rod 202. After the initial connection of the left connecting rod 201 and the right connecting rod 202 is established... After step 2, the crossbars 103 on the two adjacent bases 101 will also align. Then, the fence bars 104 can be inserted into the mounting slots on the left connecting rod 201 and the right connecting rod 202 in sequence. When installing the fence bars 104, attention must be paid to the installation direction of the fence bars 104. The recessed slots on the fence bars 104 should be aligned with the right pressure block 204. After installing each fence bar 104, the right bolt rod 205 and the left bolt rod 207 can be rotated using the Phillips head screws to make one end of the right pressure block 204 and the left pressure block 206 engage in the recessed slots on the fence bars 104. This will fix the position of the fence bars 104. At the same time, the rotation of the left bolt rod 207 will also make the top block 208 engage with the recessed circular groove on the protrusion 209, thus fixing the position of the protrusion 209. The top block 208 will also be positioned between the two rotating blocks 203, thus preventing the rotating blocks 203 from rotating. The device is now installed in this state.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
