Description

Technical Field

[0001] The invention relates to the technical field of building electrical construction, and in particular to a pre-buried wiring device used for building electrical construction. Background Art

[0002] In building electrical construction, pre-buried wiring equipment is a crucial link, which is directly related to the safety, stability and convenience of subsequent maintenance of the building electrical system. With the continuous development of modern building technology, the role of electrical systems in buildings is becoming increasingly important. Traditional building electrical installation is often carried out after the construction of the building structure is completed, which can easily cause problems such as inconvenient pipeline laying, increased leakage risks, and poor aesthetics. The pre-buried wiring technology embeds electrical pipelines into the building structure in advance, which can effectively solve these problems, improve construction efficiency, reduce maintenance costs, and reduce leakage risks. However, the existing pre-buried wiring technology did not fully consider the convenience of later wire maintenance at the beginning of the design. During the wire maintenance process, staff often need to use various maintenance tools to open the wire box. This process is not only cumbersome, but also may cause unnecessary damage to the cable when opening the wire box, increasing the difficulty and risk of maintenance.

[0003] The patent document with Chinese patent authorization announcement number CN113629648A discloses a pre-buried wiring device for building electrical construction, including a wiring box, a first protective cover, a second protective cover and a threaded column; the first protective cover and the second protective cover are installed and fixedly connected to the wiring box through the threaded column, and the first protective pads arranged at both ends of the wiring box can ensure the sealing of the contact between the ends of the wiring box, and the second protective pads arranged on the side walls of the first protective cover and the second protective cover can ensure the sealing of the contact between the first protective cover and the second protective cover. The protective cover is designed in half, and when performing partial cable inspection and replacement work, only partial removal is required, and the protective cover does not need to be removed as a whole, thereby reducing workload and improving work efficiency.

[0004] In actual application, the above patent mainly uses threaded columns to firmly install and connect the first protective cover and the second protective cover to the wiring box. However, when testing cables, it is necessary to remove multiple sets of threaded columns one by one before separating the first protective cover and the second protective cover. This process is relatively cumbersome. In addition, there is no support between the first protective cover and the second protective cover, which makes the device prone to deformation or damage when impacted by external force, affecting the safety of use.

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] See also Figures 1 to 12 As shown, the present invention provides a pre-buried wiring device for building electrical construction, including a wiring box 1 and a box cover 2, the box cover 2 is installed on the top of the wiring box 1 by bolts, a wiring block 3 is arranged on the box cover 2, a branching groove for cables to be inserted is opened on the wiring block 3, a wire clamping assembly 4 for fixing the cables is arranged on the wiring block 3, splicing assemblies 5 for assembling the wiring box 1 are arranged on both sides of the wiring box 1, a maintenance assembly 6 is arranged on the box cover 2, the maintenance assembly 6 includes a maintenance cover 61 for easy opening during maintenance and a clamping component for closing the maintenance cover 61, and an impact-resistant assembly 7 for enhancing the impact resistance of the box cover 2 is also arranged at the bottom of the box cover 2.

[0034] By fixing the wiring box 1 at the predetermined position required for the building electrical construction. After the cable is introduced into the branching groove of the wiring block 3, the cable is fixed by the wire clamping assembly 4 to prevent the cable from moving or loosening during the wiring process, thereby ensuring the stability and reliability of the electrical connection. In the case of larger-scale or more complex wiring, the wiring box 1 can be assembled with other wiring boxes 1 through the splicing assemblies 5 on both sides thereof, so that the wiring box 1 can flexibly adapt to different wiring requirements and improve the construction efficiency. When the cables inside the wiring box 1 need to be inspected or replaced, the inspection cover 61 can be easily opened, and the clamping component ensures that the inspection cover 61 can be firmly fixed on the box cover 2 when closed to prevent accidental opening, thereby ensuring the safety and stability inside the wiring box 1. During construction or use, if the wiring box 1 is subjected to external impact or vibration, the impact-resistant assembly 7 can effectively absorb and disperse these impact forces, thereby protecting the wiring box 1 and the cables inside the wiring box 1 from damage.

[0035] See also Figures 4 to 7 As shown, the clamping component includes an extension block 62; an inspection opening is provided on the top of the box cover 2, and the inspection cover 61 is rotatably set on the inspection opening, and the extension block 62 is installed on one side of the inspection cover 61; an extension groove 64 capable of being plugged and matched with the extension block 62 is provided on the top of the box cover 2 located on one side of the inspection opening, and a cylindrical groove is provided on the side of the box cover 2 located on the extension groove 64, and a fixed column 65 is slidably provided in the cylindrical groove, and a first abutting portion is provided at one end of the fixed column 65, and a pulling block 66 is provided on the top of the fixed column 65, and a second spring 67 is provided on the inner wall of the cylindrical groove, and one end of the second spring 67 abuts against the other end of the fixed column 65, and a first plug-in groove capable of being plug-matched with the first abutting portion is provided on the extension block 62.

[0036] When it is necessary to inspect or replace the cables inside the wiring box 1, the pull block 66 is pulled, and the pull block 66 drives the fixed column 65 to move, and the fixed column 65 squeezes the second spring 67 until the first abutment portion of the fixed column 65 is pulled out of the first plug-in slot of the extension block 62. At this time, the inspection cover 61 can be opened by rotation, so as to facilitate maintenance by the staff.

[0037] See also Figure 4 As shown, a handle 63 is provided on the top of the inspection cover 61 .

[0038] The handle 63 is disposed on the top of the inspection cover 61 , thereby providing a component that is easy for the user to hold and operate, so that the inspection cover 61 can be opened or closed more easily.

[0039] See also Figures 8 to 11As shown, the impact-resistant component 7 includes a buffer column 71 and a side plate 76; the buffer column 71 is arranged at the bottom of the box cover 2, a limiting plate 73 is arranged at one end of the buffer column 71, a buffer sleeve 72 is sleeved on the outer side of the limiting plate 73, the limiting plate 73 is slidably arranged in the buffer sleeve 72, a third spring 74 is arranged inside the buffer sleeve 72, one end of the third spring 74 abuts against the bottom of the limiting plate 73, the other end of the third spring 74 abuts against the inner wall of the buffer sleeve 72, an abutting rod 75 is arranged at the bottom of the buffer sleeve 72, and a second abutting portion is arranged at one end of the abutting rod 75; the side plate 76 is arranged on the inner wall of the wiring box 1, a second plug-in groove which can be plugged with the second abutting portion is arranged at the bottom of the side plate 76; a fixing component for fixing the abutting rod 75 is arranged on the side plate 76.

[0040] When the box cover 2 is installed on the top of the wiring box 1 by bolts, the fixing parts on the side plate 76 will fix the abutment rod 75. When the box cover 2 is impacted by external force, the impact force will be transmitted to the buffer column 71. The buffer column 71 will move downward after being impacted, and at the same time drive the limit plate 73 and the abutment rod 75 to move together. In this process, the third spring 74 will be further compressed to absorb and disperse the impact force, thereby improving the impact resistance of the wiring box 1 and ensuring the stability and safety of the wiring box 1 after being impacted.

[0041] See also Fig.11 As shown, the fixed component includes a moving block 710, a plug-in column 711 and a plug-in rod 712; the moving block 710 is provided with two and can move toward or away from each other and is arranged on the side plate 76, and a driving component for driving the two moving blocks 710 to move is arranged on the inner wall of the wiring box 1; the plug-in rod 712 is arranged on one side of the rightmost moving block 710; the plug-in column 711 is arranged on one side of the leftmost moving block 710, and the plug-in column 711 is provided with a third plug-in groove for inserting the plug-in rod 712; the abutment rod 75 is provided with a through hole for the plug-in rod 712 and the plug-in column 711 to move.

[0042] When it is necessary to lock the abutment rod 75, the drive assembly will start, and the two moving blocks 710 will be driven by the drive assembly to move toward each other. With the movement of the moving block 710, the plug rod 712 will gradually approach the plug post 711. When the plug rod 712 is close enough to the plug post 711, the plug rod 712 will be inserted into the third plug slot of the plug post 711 to achieve the locking of the two moving blocks 710. At this time, since the plug rod 712 and the plug post 711 both pass through the perforation on the abutment rod 75 and are locked to each other, the abutment rod 75 is also firmly fixed on the side plate 76 and cannot be easily moved. When it is necessary to unlock the abutment rod 75, the drive assembly will start again to drive the two moving blocks 710 to move back to each other. With the movement of the moving block 710, the plug rod 712 will gradually be pulled out from the third plug slot of the plug post 711. Thereby, the abutment rod 75 is no longer restricted by the plug rod 712 and the plug post 711.

[0043] See also Figures 8 to 11 As shown, the driving assembly includes a bidirectional screw rod 77 and a rack 714; a rectangular groove is provided on the inner wall of the wiring box 1, a bidirectional screw rod 77 is horizontally arranged in the rectangular groove, a driving block 78 is arranged on the bidirectional screw rod 77, a horizontal plate 79 is provided on one side of the driving block 78, one end of the horizontal plate 79 is connected to the moving block 710, a receiving groove is provided on one side of the rectangular groove of the wiring box 1, one end of the bidirectional screw rod 77 passes through one side of the rectangular groove and extends into the receiving groove, and a gear 713 is provided at the extended end of the bidirectional screw rod 77; the rack 714 is arranged at the bottom of the box cover 2 on both sides of the buffer column 71.

[0044] When the box cover 2 is closed, the rack 714 at the bottom of the box cover 2 will be inserted into the receiving grooves on both sides of the wiring box 1. As the box cover 2 continues to close, the rack 714 will push the gear 713 in the receiving groove to rotate, and the rotation of the gear 713 will drive the two-way screw rod 77 to rotate. The rotation of the two-way screw rod 77 causes the two driving blocks 78 to move toward each other, and the movement of the driving block 78 will drive the moving block 710 to move through the cross plate 79, thereby achieving the effect of driving the moving block 710 to move toward each other or away from each other.

[0045] See also Fig.12 As shown, the wire clamping assembly 4 includes a slider 42; cavities 41 are provided on both sides of the wiring block 3 on which the wire distribution groove is located, the slider 42 is slidably provided in the cavity 41, a connecting rod 43 is provided on the top of the slider 42, a pull rod 44 is connected to the top of the connecting rod 43, a first spring 45 is also sleeved on the connecting rod 43, one end of the first spring 45 abuts against the top of the slider 42, and the other end of the first spring 45 abuts against the inner wall of the cavity 41, a fixing rod 46 is provided at the bottom of the pull rod 44, and a pressure block 47 is provided at one end of the fixing rod 46.

[0046] When the cable needs to be clamped, the staff manually pulls the pull rod 44 upward. The upward movement of the pull rod 44 drives the slider 42 to slide upward in the cavity 41 through the connecting rod 43. The first spring 45 is squeezed by the sliding of the slider 42, and the cable is introduced into the branching groove of the wiring block 3. By loosening the pull rod 44, the first spring 45 restores its elastic deformation, and the restoring force of the first spring 45 pushes the slider 42 and the pull rod 44 to move downward. In this process, the pressure block 47 at one end of the fixed rod 46 will move accordingly and press on the cable, thereby completing the clamping operation of the cable and ensuring the stability and reliability of the cable in the wiring block 3.

[0047] See also Fig.12 As shown, a protective layer is attached to the bottom of the pressing block 47, and the protective layer is made of rubber material.

[0048] The rubber protective layer at the bottom of the pressing block 47 improves the clamping effect of the pressing block 47 on the cable, and because the rubber material has a certain elasticity and friction, the protective layer can absorb part of the clamping force, thereby reducing the direct pressure on the cable and protecting the cable from damage.

[0049] See also Fig.10 As shown, the splicing assembly 5 includes a splicing block 51; the splicing blocks 51 are arranged on both sides of the wiring box 1, a connecting block 52 is arranged on one side of the splicing block 51, a splicing plate 53 is arranged on the side of the splicing block 51 away from the connecting block 52, and a fourth plug-in slot for inserting the connecting block 52 is arranged in the splicing plate 53.

[0050] By aligning the connection block 52 on the wiring box 1 with the fourth plug-in slot in the splicing plate 53 on another wiring box 1 and pushing the wiring box 1 so that the connection block 52 is fully inserted into the fourth plug-in slot, flexible splicing and connection between the wiring boxes 1 is achieved.

[0051] See also Fig.10 As shown, threaded holes for bolts to be inserted are provided on the splicing plate 53 and the connecting block 52 .

[0052] After the connecting block 52 is completely inserted into the splicing plate 53, the bolts are passed through the threaded holes on the splicing plate 53 and the connecting block 52. The bolts are tightened, thereby strengthening the stability and reliability of the connection between the splicing plate 53 and the connecting block 52.

[0053] By fixing the wiring box 1 at the predetermined position required for the building electrical construction. After the cable is introduced into the branching groove of the wiring block 3, the staff manually pulls the pull rod 44 to move upward. The upward movement of the pull rod 44 drives the slider 42 to slide upward in the cavity 41 through the connecting rod 43. And through the sliding of the slider 42, the first spring 45 is squeezed, and the cable is introduced into the branching groove of the wiring block 3. By loosening the pull rod 44, the first spring 45 restores the elastic deformation, and the restoring force of the first spring 45 pushes the slider 42 and the pull rod 44 to move downward. In this process, the pressing block 47 at one end of the fixing rod 46 will move accordingly and press on the cable, thereby completing the clamping operation of the cable and ensuring the stability and reliability of the cable in the wiring block 3. In the case of larger scale or more complex wiring, the connection block 52 on the wiring box 1 is aligned with the fourth plug-in slot in the splicing plate 53 on another wiring box 1. And push the wiring box 1 so that the connection block 52 is fully inserted into the fourth plug-in slot, thereby realizing flexible splicing and connection between the wiring boxes 1. When it is necessary to inspect or replace the cables inside the wiring box 1, by pulling the pull block 66, the pull block 66 drives the fixed column 65 to move, and the fixed column 65 squeezes the second spring 67 until the first abutment portion of the fixed column 65 is pulled out from the first plug-in slot of the extension block 62. At this time, the inspection cover 61 can be opened by rotation, so as to facilitate the staff to inspect. When the box cover 2 is installed on the top of the wiring box 1 by bolts, the rack 714 at the bottom of the box cover 2 will be inserted into the receiving slots on both sides of the wiring box 1. As the box cover 2 continues to close, the rack 714 will push the gear 713 in the receiving slot to rotate, and the rotation of the gear 713 drives the two-way screw 77 to rotate. The rotation of the two-way screw 77 causes the two drive blocks 78 to move toward each other. The movement of the drive block 78 will drive the moving block 710 to move through the cross plate 79. As the moving block 710 moves, the plug rod 712 will gradually approach the plug column 711. When the plug-in rod 712 is close enough to the plug-in column 711, the plug-in rod 712 will be inserted into the third plug-in slot of the plug-in column 711 to achieve the locking of the two moving blocks 710. At this time, since the plug-in rod 712 and the plug-in column 711 both pass through the perforations on the abutment rod 75 and are locked with each other, the abutment rod 75 is also firmly fixed on the side plate 76 and cannot be easily moved. When the box cover 2 is impacted by an external force, the impact force will be transmitted to the buffer column 71. The buffer column 71 will move downward after being impacted, and at the same time drive the limit plate 73 and the abutment rod 75 to move together. In this process, the third spring 74 will be further compressed to absorb and disperse the impact force, thereby improving the impact resistance of the wiring box 1 and ensuring the stability and safety of the wiring box 1 after being impacted.

[0054] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
