Description

Technical Field

[0001] This utility model relates to the field of construction fence technology, specifically a construction fence that is easy to disassemble. Background Technology

[0002] Construction fences are safety protection facilities used at construction sites. They are mainly used for isolation and warning, effectively isolating the construction site and preventing unauthorized personnel from entering, thereby ensuring the safe and smooth progress of construction. They are commonly used in construction site foundation pits, road renovation, and road construction enclosures.

[0003] Existing patent application number: 201721849163.2 A construction fence frame and construction fence, including side posts, fastening posts, and connecting parts consisting of a union, a snap fastener and a base. The union is ring-shaped and fits onto the side post, allowing it to rotate freely around the side post and move up and down along the side post. The snap fastener is arc-shaped with a central angle greater than 180°.

[0004] The aforementioned patent describes a construction fence. Commercially available construction fences have inserts and sleeves on both sides, allowing adjacent fences to be spliced ​​together. However, due to their simple connection structure, it is difficult to lock the connection angle, resulting in poor overall structural stability of the spliced ​​fence. There is also a fence structure on the market that uses hinges. The angle of this fence can be locked by the friction of the hinges, making the overall structure of the fence more stable and less prone to deformation. However, hinge connections make it difficult to disassemble on-site, making it difficult to separate the fence for storage and transportation, and making recycling work troublesome. Therefore, we propose a construction fence that is easy to disassemble to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a construction fence that is easy to disassemble, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a construction fence that is easy to disassemble, comprising a fence body, a support frame, and a quick-release connection structure. The fence body has supports welded to its bottom left and right sides. The fence body has quick-release connection structures on its left and right side walls. Each quick-release connection structure includes a sleeve, a slot, an elbow connector, a rod, a ring bearing, a lower threaded groove, an upper threaded groove, a screw, and an adjusting knob. A sleeve is welded to the right side wall of the fence body, with a slot longitudinally extending through the sleeve. An elbow connector is welded to the left side wall of the fence body, with a rod at its bottom end. The rod can engage with the inside of the slot. The elbow connector is longitudinally inserted, and an annular bearing is installed between the elbow connector and the insert rod. The inner ring of the annular bearing is connected to the elbow connector, and the outer ring of the annular bearing is connected to the insert rod. The insert rod is rotatably connected to the elbow connector through the annular bearing. The insert rod has a longitudinally penetrating lower threaded groove, and the elbow connector has an upper threaded groove at its bottom end. The inner diameter of the upper threaded groove and the lower threaded groove are the same, and the upper threaded groove and the lower threaded groove are on the same axial line. A screw is threadedly connected inside the lower threaded groove. The top end of the screw passes through the inner ring of the annular bearing and is threadedly connected to the upper threaded groove. The bottom end of the screw extends out of the lower threaded groove and is fixed to the adjusting knob.

When the connection angle between the fence bodies needs to be adjusted, the adjustment knob is turned in the opposite direction to release the angle lock of the screw on the elbow connector and the plug rod, thus adjusting the connection angle between the fence bodies. After adjustment, the adjustment knob is turned in the forward direction to control the screw to screw upward into the inner side of the upper thread groove. The screw locks the elbow connector and the plug rod at the current angle, thus completing the angle locking operation. When the fence bodies need to be separated, the fence body is simply lifted upward until the plug rod slides out from the inside of the slot, thus completing the disassembly. The disassembly action is completed in one step, simple and quick, greatly facilitating the recycling of the fence body. Attached Figure Description

[0020] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0021] Please see Figure 1 This utility model provides a construction fence that is easy to disassemble, including a fence body 1, a support 2 and a quick-release connection structure 3. The support 2 is welded to the bottom left and right sides of the fence body 1, and the quick-release connection structure 3 is provided on the left and right side walls of the fence body 1.

[0022] Please see Figure 2-5This utility model provides a construction fence that is easy to disassemble. The quick-release connection structure 3 includes a sleeve 31, a slot 32, an elbow connector 33, a rod 34, a ring bearing 35, a lower threaded groove 36, an upper threaded groove 37, a screw 38, and an adjusting knob 39. The sleeve 31 is welded to the right side wall of the fence body 1, and the slot 32 is longitudinally provided inside the sleeve 31. The elbow connector 33 is welded to the left side wall of the fence body 1, and the bottom end of the elbow connector 33 is provided with a rod 34. The rod 34 can be longitudinally inserted into the inside of the slot 32. A ring bearing 35 is installed between the elbow connector 33 and the rod 34, and the inner ring of the ring bearing 35 is connected to the elbow. The components 33 are connected together. The outer ring of the ring bearing 35 is connected to the insert rod 34. The insert rod 34 is rotatably connected to the elbow connector 33 through the ring bearing 35. The insert rod 34 has a longitudinally through-hole lower threaded groove 36. The elbow connector 33 has an upper threaded groove 37 at the bottom. The upper threaded groove 37 and the lower threaded groove 36 have the same inner diameter and are on the same axial line. The lower threaded groove 36 is threadedly connected to a screw 38. The top of the screw 38 passes through the inner ring of the ring bearing 35 and is threadedly connected to the upper threaded groove 37. The bottom of the screw 38 extends out of the lower threaded groove 36 and is fixedly installed with the adjusting knob 39.

[0023] To further explain, the slot 32 and the insertion rod 34 have the same cross-sectional shape and are both polygonal structures, which locks the angle of the insertion rod 34 after it is inserted into the inside of the slot 32 and prevents it from rotating.

[0024] To further explain, the length of the insert 34 is greater than the length of the slot 32, ensuring that the insert 34 can completely pass through the slot 32, thus preventing the adjustment knob 39 from being stuck inside the slot 32 and becoming unusable.

[0025] To further explain, the length of the upper threaded groove 37 is not less than 2cm, so as to ensure that the screw 38 and the upper threaded groove 37 have sufficient connection length and are not easy to fall off accidentally.

[0026] To further explain, the length of the screw 38 is greater than the sum of the lengths of the lower threaded groove 36 and the upper threaded groove 37, ensuring that the screw 38 can be fully screwed into the inner side of the lower threaded groove 36 and the upper threaded groove 37 to lock the angle of the elbow connector 33 and the insert rod 34.

[0027] To further explain, the outer diameter of the adjusting knob 39 is smaller than the inner diameter of the slot 32, ensuring that the insert rod 34 can slide out of the inside of the slot 32 without obstruction, making disassembly convenient and requiring no additional action.

[0028] The working principle is as follows:

[0029] First, the main body 1 of the fence is placed on the ground using the bracket 2. Adjacent fence bodies 1 can be connected by a quick-release connection structure 3 to better surround and isolate the construction site.

[0030] Second, when adjacent fence bodies 1 are connected, the insertion rod 34 of the right fence body 1 is aligned with the insertion sleeve 31 of the left fence body 1, and then the insertion rod 34 is inserted from top to bottom through the slot 32. The fence bodies 1 on both sides can be connected by the insertion rod 34 and the insertion sleeve 31. The cross-sectional shape of the slot 32 and the insertion rod 34 is a polygonal structure. After they are inserted into each other, the angle is locked and cannot be rotated, making the overall structure of the fence bodies 1 after connection more stable and less prone to deformation.

[0031] Third, when it is necessary to adjust the connection angle between the main bodies 1 of the fence, turn the adjustment knob 39 in the opposite direction to control the screw 38 to rotate downward out of the upper threaded groove 37, so that the top of the screw 38 retracts into the lower threaded groove 36, thereby releasing the angle lock of the screw 38 on the elbow connector 33 and the insert rod 34, so that the ring bearing 35 returns to the active state, and the connection angle between the main bodies 1 of the fence can be adjusted. After the adjustment is completed, turn the adjustment knob 39 in the forward direction to control the screw 38 to rotate upward into the inner side of the upper threaded groove 37, and lock the elbow connector 33 and the insert rod 34 at the current angle through the screw 38, thus completing the angle locking operation.

[0032] Fourth, when it is necessary to separate the main body 1 of the fence, simply lift the main body 1 upwards until the insert 34 slides out from the inside of the slot 32, and the disassembly can be completed in one step. This is simple, quick and easy, and greatly facilitates the recycling of the main body 1 of the fence.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
