Description

Technical Field

[0001] The utility model relates to the technical field of supports for pre-buried indoor electric boxes, in particular to an internal support device for pre-buried indoor electric boxes in concrete shear walls. Background Art

[0002] In current building construction projects, the quality control of pre-embedded indoor electrical boxes in concrete shear walls presents numerous challenges. In particular, the inward deformation of the box housing during concrete pouring has become a pressing issue. This not only impacts the installation quality of the box but also the overall quality and safety of the project. The following are specific construction methods currently available:

[0003] 1) Using block foam filling is a common method. Foam is chosen for its light weight, easy formability, and low price. By filling the space around the electrical box, it provides support and prevents the casing from deforming under pressure during concrete pouring. However, in practice, this method is affected by multiple factors, including human factors, material quality, and construction techniques. For example, uneven or insufficient foam filling and negligence by construction workers can lead to ineffective protection.

[0004] 2) Internal support using wooden planks. As a traditional support material, wooden planks are widely used in engineering projects. However, this method is also subject to numerous uncontrollable factors. The selection of the planks, their processing accuracy, and their installation location all directly impact their support effectiveness. Furthermore, because wood is inherently hygroscopic, changes in ambient humidity can weaken its support, thereby affecting the stability of the electrical box housing. Despite implementing these two measures, inward collapse of the electrical box housing still occurs frequently in actual construction. Utility Model Content

[0005] The purpose of the utility model is to provide an internal support device for a pre-buried indoor electrical box in a concrete shear wall, thereby ensuring stable support for the pre-buried indoor electrical box during use, thereby avoiding deformation of the electrical box.

[0033] The present invention is described in detail below with reference to the various embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in this field based on these embodiments are all within the scope of protection of the present invention.

[0034] Refer to the attached Figure 1-5 As shown, the internal support device of the indoor electrical box embedded in the concrete shear wall in this embodiment includes an electrical box 1 and a rotating shaft 2 provided through the electrical box 1; in order to cleverly utilize the rotating shaft 2 to generate power, it also includes a horizontal support mechanism 6 and a vertical support mechanism 5 located in the electrical box that are simultaneously linked with the rotating shaft 2, and then the rotating shaft 2 is synchronously linked to drive the horizontal support mechanism 6 and the vertical support mechanism 5 to perform horizontal telescopic movement and vertical lifting movement respectively, so as to support the electrical box 1; and then when the electrical box 1 is deformed, its overall stability is ensured by horizontal and vertical support.

[0035] In this embodiment, in order to ensure the support and stabilization effect after adjustment, a locking mechanism 4 is also included which is connected to the rotating shaft 2 and moves synchronously therewith. The locking mechanism 4 also includes a knob 45 which extends out of the electrical box 1 and controls the locking mechanism. The knob 45 locks or unlocks the locking mechanism 4, driving the rotating shaft 2 to stop moving or resume moving.

[0036] In this embodiment, the horizontal and vertical support mechanisms provide a more stable and reliable support effect. This design effectively reduces the risk of deformation of the distribution box due to squeezing during the pouring process, thereby ensuring construction quality and safety.

[0037] In this embodiment, in order to save space as much as possible, the rotating shaft 2 is used as the entire driving mechanism, and then the horizontal support mechanism and the vertical support mechanism are connected to the rotating shaft through meshing. During rotation, the rotational direction of movement is changed to linear direction movement through meshing, and the synchronous driving of movements in different directions is achieved.

[0038] The following is an introduction to the horizontal support structure and the vertical support mechanism.

[0039] First, the horizontal support is introduced as follows:

[0040] Refer to the attached Figure 1As shown in Figures 2-3, the horizontal support mechanism 6 includes a first gear 61 mounted on the rotating shaft 2. The first gear 61 engages with a first rack 62 and a second rack 63 symmetrically arranged horizontally. The rotating shaft then drives the first gear 61 to rotate, causing the two racks to move closer or further away from each other, thereby shortening or lengthening them horizontally to match the different horizontal support lengths within the electrical box.

[0041] In order to ensure more stable contact with the electrical box, the two ends of the horizontal support mechanism 6 are vertically connected to connecting rods 64, and a support rod 65 is provided at the upper or lower part of each connecting rod 64. At this time, the ends of the connecting rods 64 are vertically thickened, so that the connecting rods 64 can contact the inner wall of the electrical box to provide better support.

[0042] Since the horizontal length is generally long, a pressure plate can be added. In this case, a sliding sleeve 66 is provided on the support rod 65, and a pressure plate 7 is provided below the sliding sleeve 66 to provide support. This is suitable for long electrical boxes. Of course, to prevent the end of the pressure plate from being smooth and causing instability, a number of anti-slip protrusions 71 are provided on the end of the pressure plate 7 to improve the stability of the contact with the inner wall of the electrical box.

[0043] At this time, the working principle of the horizontal support mechanism is as follows:

[0044] The horizontal support mechanism 6 includes a first gear 61 formed by a horizontal gear, which is mounted on the rotating shaft 2 formed by the central axis. Two horizontal sleeves 66 are provided in the electrical box, and a horizontal support rod 65 is slidably fitted in the two horizontal sleeves. The support rod is connected to a connecting rod 64, and the two connecting rods are respectively connected to a horizontal left rack and a horizontal right rack, and the horizontal left rack and the horizontal right rack are meshed with the horizontal gear. During support, the horizontal support mechanism realizes precise lateral support adjustment through gear rack transmission, and the anti-slip protrusions on the pressure plate enhance the stability of the support. This design improves the stability and adjustment accuracy of the support device. In this embodiment, a scale can also be set on the support rod 65, and then a visual window is added to the electrical box 1, so that the extended length can be observed with the naked eye.

[0045] Secondly, the vertical support mechanism is introduced as follows:

[0046] Refer to the attached Figure 1 and 4 As shown, the vertical support mechanism 5 in this embodiment includes a second gear 51 mounted on the rotating shaft 2. The second gear 51 is engaged with a third rack 52 and a fourth rack 53 arranged symmetrically in the vertical direction. In this case, the rack is perpendicular to the horizontal direction, thereby achieving height adjustment in another direction.

[0047] The vertical support mechanism comprises a second gear 51, a vertical left rack, and a vertical right rack. This structure is identical to the horizontal support mechanism, but the two are mounted at a different angle, at a 90° angle. This effectively supports the electrical box from top to bottom, as well as from side to side. The vertical and horizontal support mechanisms are perpendicular to each other, ensuring stable support in multiple directions. This structural layout enhances the all-around stability of the support mechanism.

[0048] Again, the one-way locking in this embodiment is introduced.

[0049] In this embodiment, the locking mechanism 4 includes a ratchet 41 fixed to the rotating shaft 2, and a pawl 43 with a torsion spring 44 fixed in the electrical box 1. In this embodiment, the locking mechanism 4 includes a ratchet 41 fixed to the rotating shaft 2, and a pawl 43 fixed in the electrical box 1. When the ratchet 41 rotates, the ratchet 41 and the pawl 43 are tangentially aligned in the same direction, so that the ratchet 41 is always in a rotating state. When locking is required, it is only necessary to turn the knob so that the pawl, which was originally aligned with the ratchet, faces the slot between adjacent gears on the ratchet. At this time, the ratchet is clamped and cannot rotate, completing the one-way locking.

[0050] Furthermore, to facilitate control, the knob 45 is connected to a rotating rod 42, and the pawl 43 is sleeved on the rotating rod 42 and connected to a torsion spring 44 on the rotating rod 42. The torsion spring is provided on the rotating rod to fix and limit the movement of the pawl. At this time, it is in a stationary state. However, when the knob 45 is rotated, the rotating rod 42 rotates synchronously, causing the pawl to move under force. Once the knob is rotated in the opposite direction, the pawl and torsion spring reset, and the ratchet wheel continues to rotate, completing the unlocking.

[0051] Specifically, to prevent the inner support from loosening during tightening, the one-way locking mechanism includes a ratchet 41, a pawl 43, and a rotating rod 42. The ratchet is fixed to the central shaft, and the ratchet, vertical gear, and horizontal gear are coaxial. The rotating shaft is rotatably connected to the mounting box. The upper end of the rotating shaft is provided with a knob 45, and the lower end of the rotating shaft is fixedly connected to the pawl. A torsion spring is provided between the pawl and the mounting box. The torsion spring 44 enables the pawl to cooperate with the ratchet, and turning the knob can separate the pawl from the ratchet. The one-way locking mechanism effectively prevents the support device from loosening during the tightening process through the cooperation of the ratchet and pawl, thereby improving the safety and reliability of use. This design enhances the stability and durability of the support device.

[0052] In this embodiment, an inner box 8 can be added, and then the movement of the locking mechanism is limited in the inner box 8. At the same time, the two racks in the horizontal support mechanism and the two racks in the vertical support mechanism are respectively passed through the inner box 8. The inner box 8 can form further intermediate protection. Of course, there is no need to add the inner box 8 and the assembly can be carried out directly.

[0053] Finally, the assembly of the handle and the rotating shaft is introduced.

[0054] Refer to the attached Figure 1 It can be seen that the handle assembly 3 for controlling the movement direction of the rotating shaft 2 is also included. The handle assembly 3 includes a rotating rod 31 sleeved on the rotating shaft, and a hand-held rod 32 on the side of the rotating rod.

[0055] In this embodiment, the end of the rotating rod 31 is provided with a mounting hole that mates with the rotating shaft 2. The gripping rod, which forms the hand-held handle, is rotatably connected to the end of the rotating rod, with the gripping rod located at the end away from the mounting hole. The handle design allows the operator to more conveniently rotate the rotating shaft, thereby easily adjusting the support device. This improvement enhances user experience and ease of operation.

[0056] To ensure stable rotation, a bearing seat 7 is located at the bottom of the electrical box 1, and the rotating shaft 2 is assembled on this bearing seat 7. The bearing seat provides stable rotational support for the rotating shaft, ensuring smoothness and precision during adjustment of the support device. This design helps improve the overall performance and durability of the support device.

[0057] The working process in this embodiment is described as follows:

[0058] First, place the entire installation box of the internal support device inside the electrical box that needs to be supported. Make sure that the rotating shaft 2 formed by the central axis can rotate freely in the electrical box 1 through the bearing seat 7. Rotate the handle assembly 3 on the rotating shaft 2 to drive the first gear to rotate through the central axis. The rotation of the first gear will drive the horizontal left rack and the horizontal right rack to move to both sides of the electrical box because they are engaged with the horizontal gear. The movement of the horizontal rack pushes the horizontal support rod to slide in the horizontal sleeve through the connecting rod until the pressure plate fits tightly against the inner wall of the electrical box. The anti-slip protrusions on the pressure plate can enhance the support stability and prevent sliding. Similarly, by rotating the central axis, the vertical gear will drive the vertical left rack and the vertical right rack to move up and down. The movement of the rack will support the upper and lower parts of the electrical box, providing stable support in the vertical direction.

[0059] Once the horizontal and vertical supports are adjusted, they must be locked with a one-way locking mechanism to prevent them from loosening. The ratchet in the one-way locking mechanism rotates synchronously with the central shaft. When the desired support position is reached, the pawl, acting under the action of a torsion spring, automatically engages the ratchet's tooth groove, preventing the central shaft from rotating. To unlock and adjust the support position, rotate the knob, which disengages the pawl from the ratchet via the rotating shaft. Ensure that all mechanisms and components are adjusted and locked in place, ensuring that the electrical box is stably supported both horizontally and vertically.

[0060] When support is no longer needed, first unlock the one-way locking mechanism using the knob. Reverse the handle to retract the horizontal and vertical supports, then remove the entire internal support assembly from the electrical box. With these steps, the internal support assembly for the indoor electrical box embedded in a concrete shear wall effectively provides stable support for the box and prevents it from loosening or shifting during support.

[0061] In this embodiment, the horizontal and vertical support mechanisms can be adjusted synchronously by rotating the shaft, achieving fast and uniform support adjustment. This design makes the operation of the support device simpler and more efficient.
