TECHNICAL FIELD

[0001] The utility model belongs to the technical field of safety protection fence, specifically relates to an angle adjustable protection fence. BACKGROUND

[0002] In the modern engineering construction process, the safety protection fence of construction area is extremely common, along with the higher and higher safety civilized construction requirement standard, the quality requirement and applicable scene requirement of protection fence are also higher and higher.

[0003] However, at present, the conventional vertical protection fence cannot effectively protect the critical region of high-altitude falling objects because its protection surface is perpendicular to the ground. Although the top of some vertical protection fences has a certain inclination, it can protect some high-altitude falling objects, but the inclination angle is not adjustable, so the critical range of protecting high-altitude falling objects is not adjustable, and the adaptability is poor. UTILITY MODEL CONTENTS

[0004] In view of the above problems, the application provides an angle adjustable protection fence, which solves the problems of ordinary vertical protection fence that cannot protect high-altitude falling objects and the critical range of high-altitude falling objects being not adjustable.

[0005] The technical scheme adopted is as follows:

[0006] An angle adjustable protection fence comprises:

[0007] A plurality of connecting sleeves are coaxially and spaced apart, and a plurality of clamping grooves are spaced apart in the direction of the arc on each connecting sleeve;

[0008] A plurality of protection fences are fixedly connected with connecting pipes at the lower ends of each protection fence, and a cooperating groove is arranged at both ends of each connecting pipe, the connecting pipes of the plurality of protection fences are rotatably inserted into the connecting sleeves, and the cooperating grooves at both ends are overlapped with the clamping grooves by rotating the protection fence;

[0009] A clamping pin is used to be inserted into the clamping groove and the cooperating groove when the cooperating groove and the clamping groove are overlapped.

[0010] Optionally, a plurality of bases are further arranged, and the plurality of connecting sleeves are fixedly connected with the bases.

[0011] Optionally, a clamping ring is further arranged on the base, and the clamping ring and the protection fence are connected by a steel wire rope.

[0012] Optionally, an anchoring hole is further arranged on the base.

[0013] Optionally, the plurality of connecting sleeves are fixedly connected with the upper end of the vertical fence.

[0014] Optionally, the multiple card slots are distributed in 10° increments within an angular range.

[0015] Optionally, the length of the locking pin is at least greater than the wall thickness of the connecting sleeve.

[0016] Optionally, the length of the locking pin is greater than or equal to the sum of the wall thicknesses of the connecting sleeve and the connecting tube.

[0017] Optionally, the shape and size of the mating groove are the same as the shape and size of the card slot.

[0018] Optionally, the shape and size of the pin inserted into the slot and mating groove are the same as the shape and size of the slot.

[0019] This utility model of an adjustable-angle protective fence has the following beneficial effects:

[0020] (1) The adjustable angle protective fence adopts a modular splicing method. The connection between each component does not require welding. The range of protection against falling objects from height can be adjusted by adjusting the angle, which is conducive to promotion and is especially suitable for construction protection needs where the work surface moves quickly.

[0021] (2) The adjustable angle protective fence adopts a steel wire rope pulling structure and base anchoring structure, which provides multiple insurance and enhances the overall stability and reliability of the adjustable angle protective fence.

[0022] (3) When the adjustable angle protective fence is used, the wire rope pulling surface is the front of the protective surface. When carrying out edge protection during earthwork slope construction, the extended base foot plate can be covered with earthwork first. At this time, the combined protective fence can play the role of a cantilever retaining wall. The more earthwork falls from above, the better the overall stability of the fence and the better the protection effect.

[0023] (4) The structural features of the adjustable angle protective fence determine its advantage of saving land. It can be placed on the outer side of the slope support surface as much as possible. The inner extension base provides reliable anchoring stability. After adjusting the angle, its protective surface can even extend beyond the outer side of the edge. It can play a targeted and irreplaceable protective role in some narrow working areas.

[0024] (5) The adjustable angle protective fence can be disassembled without damage, has a high reuse rate, and greatly reduces the cost of use.

[0025] (6) This adjustable angle protective fence can also be applied to the top of a vertical fence. By adjusting the angle, the range of protection against falling objects from heights can be adjusted. Attached Figure Description

[0034] The embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art will recognize that the described embodiments can be modified in various ways or combinations thereof without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims. Furthermore, in this specification, the drawings are not drawn to scale, and the same reference numerals denote the same parts.

[0035] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. "Rotary connection" refers to a connection where the components can rotate relative to each other after connection. The directional terms mentioned in the embodiments of this application, such as "upper," "lower," "inner," and "outer," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0036] This application provides an adjustable angle protective fence, which can be used alone, for example, anchored to a support surface below a slope, or installed on the upper part of a vertical fence. Through the cooperation of slots and pins, the tilt angle of the fence can be adjusted to facilitate the adjustment of the critical range of the fence for protecting against falling objects from heights.

[0037] The adjustable-angle protective fence of this embodiment includes a connecting sleeve 10, slots 2, locking pins 3, and a fence 6. The connecting sleeve 10 is a cylindrical tube, and multiple slots are spaced apart along an arc direction on the connecting sleeve 10. The arc is a segment of the circumference of the connecting sleeve 10. The slots can be, for example, square, circular, or strip-shaped. This embodiment uses a strip-shaped slot as an example. Multiple strip-shaped slots 2 are spaced apart along an arc direction on the connecting sleeve 10, and the slots 2 penetrate the tube body of the connecting sleeve 10.

[0038] The fence has a conventional structure, for example, it may include multiple horizontal bars and connecting rods at both ends of the horizontal bars. There are no restrictions on the specific structure of the fence; any shape and structure is acceptable. A connecting pipe 61 is connected to the lower end of the fence 6, with both ends extending beyond the fence to be inserted into the corresponding connecting sleeve 10. A mating groove 62 is provided at both ends of the connecting pipe 61. The shape and size of the mating groove 62 are the same as the slot 2. For example, if the slot 2 is circular, the mating groove 62 is also circular; if the slot is strip-shaped, the mating groove is also strip-shaped. The connecting pipe 61 is inserted into the connecting sleeve 10 and is rotatably connected to the connecting sleeve 10. By rotating the connecting pipe 61, the mating groove 62 can be aligned with one of the multiple slots 2.

[0039] The lower end of the locking pin 3 has the same shape and size as the locking groove 2, allowing the locking pin 3 to be inserted into the locking groove 2. Furthermore, the length of the locking pin 3 should be at least greater than the wall thickness of the connecting sleeve 10, so that the lower end of the locking pin 3 can pass through the connecting sleeve 10 and into the mating groove 62. Preferably, the length of the locking pin 3 is greater than or equal to the sum of the wall thicknesses of the connecting sleeve 10 and the connecting tube 61, allowing the lower end of the locking pin 3 to simultaneously enter both the locking groove 2 and the mating groove 62, thereby reliably limiting the relative rotation of the connecting sleeve and the connecting tube.

[0040] In some embodiments, the angle range of the card slots 2 can be set in 10° increments, with a maximum adjustable angle of 80°, such as... Figure 2As shown, nine slots 2 are set within an 80° angle range. When the mating slot 62 coincides with one of the slots 2, the locking pin 3 is inserted into the slot 2 and the mating slot 62, thus restricting the relative rotation between the connecting sleeve 10 and the connecting pipe 61, and consequently limiting the tilt angle of the fence 6. Pulling out the locking pin 3 and rotating the connecting pipe 61 so that its mating slot 62 coincides with another slot allows the fence 6 to rotate by one angle, increasing the critical range of protection against falling objects. Continuing to rotate the connecting pipe 61 so that its mating slot 62 coincides with the next slot allows the fence 6 to rotate by another angle, further increasing the critical range of protection against falling objects.

[0041] The connecting sleeve and base 1 can be fixedly connected. For example, the connecting sleeve 10 can be welded to the base 1. Two bases are needed for one fence, three bases for two fences, and N+1 bases for N fences. By inserting the connecting pipe 61 of the fence 6 into the connecting sleeve on the corresponding base, and inserting the locking pin 3 into the slot and mating groove, the fence and base can be connected as one unit. To achieve a consistent protective effect, all fences can adopt the same tilt angle. That is, the mating groove 62 of the connecting pipe 61 of the fence 6 mates with the slot at the same position on the connecting sleeve, so that all fences maintain the same tilt angle.

[0042] Furthermore, a retaining ring 5 is also provided on the base 1 as an anchor point for the wire rope. The retaining ring 5 can be connected to the fence by the wire rope 4. Specifically, one end of the wire rope 4 is connected to the upper end of the fence, and the other end is connected to the retaining ring 5, which can enhance the stability of the modular fence.

[0043] Furthermore, the base 1 is also provided with anchoring holes 7, which can be used to insert temporary anchoring components such as steel bars or nails as needed to anchor the base 1 to the support surface below the slope, thereby further enhancing the stability and impact resistance of the protective fence.

[0044] The following explains how to use this adjustable angle protective fence. In use, it can be done as follows: Figure 3As shown, base 1 is anchored to the support surface below the slope, allowing the fence to extend from the support surface and thus protect personnel below. Multiple adjustable-angle protective fences can be made according to the length of the slope support surface. During the anchoring of base 1, the connecting pipe 61 at the bottom of the fence is inserted into the connecting sleeve 10, the slot and the mating groove are aligned, and then a locking pin is inserted into the slot and the mating groove to form a temporary assembly structure connecting the fence and the base. As needed, the mating groove can be adjusted to align with different slots to adjust the fence angle. In actual use, steel wire ropes and anchoring holes can be selectively used according to the impact resistance requirements. The steel wire rope is anchored to the locking ring 5 of the base and the upper end of the fence to enhance the stability of the combined fence. The anchoring holes can be used to insert temporary anchoring components such as steel bars or nails to anchor the base to the support surface below, thereby further enhancing the stability and impact resistance of the protective fence.

[0045] Furthermore, this application does not limit the application of this adjustable-angle protective fence to construction sites; it can also be used on fences in residential areas, scenic spots, and other similar locations. The connecting sleeve is fixedly connected to the upper end of the vertical fence, for example... Figure 3 As shown, it can be welded to the vertical fence 100. The adjustable angle protective fence located at the top of the vertical fence can also be adjusted to change its tilt angle to provide different critical ranges for protecting against falling objects from heights.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
