DETAILED DESCRIPTION

[0043] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0044] As described in the background, workers will use a chain to connect adjacent fences together, in this way, since the number of fences is large, a large number of chains need to be purchased, resulting in an increase in construction cost, and the chain locking and unlocking operation is complicated, workers need to spend a lot of time to unlock and lock one by one, resulting in an increase in labor and time cost.

[0045] Based on this, the present application provides a combined fence, aiming at solving the technical problem of complicated connection between adjacent fences.

[0046] Reference Figure 1 and Figure 6 A combined fence, comprising: at least two fences 10; a connecting piece 20, provided with at least two hole sites 30, the hole sites 30 being used for inserting the support legs 100 of the fences 10 to connect the adjacent fences 10; a support leg 100, comprising an adjusting mechanism 1000 and at least two sub-support legs 1001, the adjusting mechanism 1000 and the sub-support legs 1001 being connected, used for adjusting the included angle between different sub-support legs 1001 to adapt to the spacing of different hole sites 30; a clamping piece 40, comprising a first clamping plate 401 and a second clamping plate 402, the opposite ends of the first clamping plate 401 being provided with a first arc structure 4010, the opposite ends of the second clamping plate 402 being provided with a second arc structure 4020, the first arc structure 4010 and the second arc structure 4020 cooperating to form a clamping structure for clamping the fence 10.

[0047] The fence 10 is used to isolate the construction site and the surrounding environment, and the staff performs construction work in the circle surrounded by the fence 10 or the semi-open range. The connecting piece 20 is provided with a plurality of hole positions 30, and the supporting legs 100 can be inserted to make the fence 10 stand up to play a blocking role. The supporting legs 100 of the adjacent two fences 10 are inserted into the same connecting piece 20, which realizes the convenient and fast connection of the two fences 10. When the connection between the adjacent two fences 10 is disconnected, only the supporting legs 100 need to be pulled out of the hole positions 30, which is simple to operate and saves time and effort, thereby improving the work efficiency during construction and installation.

[0048] Reference Figure 1 It is obvious that one connecting piece 20 can connect two fences 10. When the number of fences 10 is much greater than 2, in one case, the number of fences 10 is n, and the number of connecting pieces is n, so that the same number of settings makes the finally formed combined fence can surround a circle; in another case, the number of fences 10 is n, and the number of connecting pieces 20 is n-1. Since the fence 10 usually includes two supporting legs 100, the two fences 10 on the outermost side of the combined fence have a suspended supporting leg 100, which does not need to be inserted into the connecting piece 20, and can be placed close to the wall or building facilities to form a door opening and closing mechanism with the supporting leg 100 inserted into the connecting piece 20 as a fulcrum, so that the staff can enter and exit the construction site; in another case, the number of fences 10 is n, and the number of connecting pieces 20 is n+1. Such a setting makes each supporting leg 100 of the combined fence inserted into the connecting piece 20, and the combined fence can be arranged into a corresponding shape according to the actual construction site range.

[0049] Reference Figure 2 When the supporting leg 100 has one sub-supporting leg 1001, i.e., only one supporting leg 100, it only needs to be inserted into any hole position 30; when the supporting leg 100 has a plurality of sub-supporting legs 1001, the angle between different sub-supporting legs 1001 can be adjusted by the adjusting mechanism 1000, so that different sub-supporting legs 1001 can be accurately inserted into the corresponding hole positions 30, avoiding the problem that the fixed angle between different sub-supporting legs 1001 cannot be smoothly inserted, thereby improving the stability of the sub-supporting leg 1001.

[0050] In some embodiments, reference Figure 2 The supporting leg 100 has three sub-supporting legs 1001, and the angle between the three sub-supporting legs 1001 is adjusted by the adjusting mechanism 1000, so that the range of the angle is 45° to 75°. The sub-supporting leg 1001 after such adjustment can adapt to the spacing of different hole positions 30 and be accurately inserted into the hole positions 30.

[0051] Preferably, reference Figure 3The combination fence further comprises a sliding mechanism 50 and a locking mechanism (not shown in the figure); the fence 10 comprises a first sub-fence 11 and a second sub-fence 12, the top end of the second sub-fence 12 is provided with a handle part 120, the second sub-fence 12 is moved along the height direction of the first sub-fence 11 by pulling the handle part 120 through the sliding mechanism 50; when moved to a preset height position, the second sub-fence 12 is locked on the first sub-fence 11 by using the locking mechanism; wherein the initial position is that the feet 100 of the first sub-fence 11 and the second sub-fence 12 respectively maintain a preset distance.

[0052] With reference to Figure 3 The sliding mechanism 50 comprises a sliding rail and a sliding block (both not shown in the figure), the sliding block is arranged in one of the first sub-fence 11 and the second sub-fence 12, and the sliding rail is arranged in the other one of the first sub-fence 11 and the second sub-fence 12. In the initial state, the second sub-fence 12 is arranged higher than the first sub-fence 11, and the feet 100 of the second sub-fence 12 and the feet 100 of the first sub-fence 11 maintain a preset distance, so that the staff can pull the second sub-fence 12 through the handle part 120 to move the second sub-fence 12 up and down along the height direction of the first sub-fence 11, avoiding the problem that the second sub-fence 12 and the first sub-fence 11 overlap to cause the pulling of the handle part 120 to be not smooth.

[0053] In some embodiments, the locking mechanism comprises a fixing block (not shown in the figure) arranged on the side of the second sub-fence 12 close to the first sub-fence 11, for locking the second sub-fence 12 on the first sub-fence 11 after the second sub-fence 12 reaches the designated position, so that the second sub-fence 12 cannot continue to move.

[0054] With reference to Figure 1 and Figure 8 After the feet 100 of the fence 10 are inserted into the hole positions 30, in order to further ensure the stability of the connection, first, the first clamping plate 401 is placed behind the fence 10 post, and then the second clamping plate 402 is placed in front of the fence 10 post, so that the first arc-shaped structure 4010 and the second arc-shaped structure 4020 cooperate to form a clamping structure to clamp the fence 10 post located therein. In actual application, the clamping part 40 is arranged between two fences 10 arranged close to each other, the left clamping structure clamps the left fence 10, and the right clamping structure clamps the right fence 10, so as to achieve the effect of reinforcing the connection between the fences 10 and improve the fixing ability between the fences 10.

[0055] Preferably, with reference to Figure 1 and Figure 6 The shape of the hole position 30 is determined according to the shape of the feet 100.

[0056] In some embodiments, the foot 100 is in a cylindrical structure, and the hole 30 is a circular hole with a radius slightly smaller than the cross-sectional radius of the foot 100. In this way, the foot 100 needs to bear a certain resistance when inserted into the circular hole, so that the foot 100 can be stably inserted into the circular hole.

[0057] In some embodiments, the foot 100 is in a cuboid structure, and the hole 30 is a circular hole with a radius slightly smaller than the diagonal length of the cross-sectional rectangle of the foot 100. Alternatively, the hole 30 can be a rectangular hole that matches the size of the cross section of the foot 100.

[0058] In some embodiments, the cross section of the foot 100 is approximately rectangular, and the hole 30 is a waist-shaped hole. In some cases, the foot 100 with a cylindrical structure or a cuboid structure is also suitable in size and can be inserted into the waist-shaped hole.

[0059] Preferably, the hole 30 penetrates the connector 20, and the depth of the hole 30 is not greater than the length of the foot 100.

[0060] If the depth of the hole 30 is less than the length of the foot 100, the foot 100 will be partially inserted into the hole 30, and the other part will be exposed, causing the foot 100 to be unbalanced when subjected to external force, and prone to shaking, which is not conducive to improving the stability of the fence connection. Therefore, the depth of the hole 30 is set to be greater than or equal to the length of the foot 100, so that the foot 100 is inserted into the hole 30 as a whole, ensuring the stability of the assembled fence.

[0062] The cuboid structure facilitates the direct placement of the connector 20 on the ground. When the foot 100 is inserted into the connector 20, pressure is applied to the connector 20, increasing the friction between the connector 20 and the ground, ensuring that the connector 20 will not be easily displaced. At the same time, the arc-shaped surfaces 200 facilitate the worker's grip to place the connector 20 on the ground before the connection operation and to pick it up after the disconnection operation.

[0063] Preferably, referring to Figures 4 to 6 , the hole 30 includes a first hole 300 and a second hole 301, and the first hole 300 and the second hole 301 are different in shape; the first hole 300 and the second hole 301 are arranged into at least two hole groups, and the hole groups are symmetrically arranged at opposite ends of the connector 20.

[0066] In some embodiments, referring to Figure 6 The fence 10 has a cylindrical structure. Two adjacent fences 10 are connected by inserting the leg 100 of the left fence 10 into the first hole 300 at the upper left corner and inserting the leg 100 of the right fence 10 into the first hole 300 at the upper right corner. It should be noted that the figure is only an example. In actual application, the leg 100 can be inserted into any first hole 300. If the size and shape of the leg 100 are appropriate, the leg 100 can also be inserted into any second hole 301.
