Description

Technical Field

[0001] The utility model relates to the technical field of movable board houses, in particular to a wall panel connection structure used for movable board houses. Background Art

[0002] As a new type of prefabricated building model, prefabricated houses have been widely used and recognized in many fields due to their advantages such as stable structure, high efficiency and convenience, green environmental protection, flexibility and diversity, and neat appearance. At present, common prefabricated houses usually have four L-shaped connecting plates as the pillars of the house, and wall panels are installed between these L-shaped connecting plates to complete the construction. However, the existing wall panels and L-shaped connecting plates are mostly connected by bolts, which is relatively cumbersome for prefabricated houses that need to be frequently disassembled and installed.

[0003] In order to solve the above problems, the patent with patent announcement number CN220225721U discloses a mobile house connection device, including an L-shaped connection plate, both side walls of the L-shaped connection plate are provided with slots, both slots are inserted with wall panels, and a fixing mechanism is provided between the wall panel and the L-shaped connection plate, the fixing mechanism includes two limiting holes and a cross plate, the two limiting holes are respectively provided on both sides of the wall panel, the cross plate is placed on one side of the L-shaped connection plate, and a moving mechanism is provided between the cross plate and the L-shaped connection plate. The connection device can fix the wall panel inserted in the slot of the side wall of the L-shaped connection plate through the fixing mechanism, and when the wall panel needs to be disassembled, it only needs to turn the handle.

[0004] However, the above scheme still has some shortcomings in the implementation process. Since the depth of the wall panel inserted into the L-shaped connecting plate is limited, the wall panel still needs to be supported after insertion to prevent the wall panel from falling out of the L-shaped connecting plate, thereby ensuring that the limit rod can be smoothly inserted into the limit hole. In addition, components such as threaded rods, cross plates and handles are all exposed on the surface of the L-shaped connecting plate. After long-term use, these components are easily affected by environmental factors such as sun and rain, thereby greatly shortening their service life. Utility Model Content

[0018] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment: A wall panel connection structure for a mobile house, such as Figure 1-Figure 4 As shown, it includes a base 1, an L-shaped connecting plate 2 and a wall panel 3. An L-shaped connecting plate 2 is welded and fixed on the top of the base 1. A through cavity is opened in the middle of the L-shaped connecting plate 2. The wall panel 3 is slidably arranged on the right and rear sides of the L-shaped connecting plate 2. It also includes a locking assembly, an unlocking assembly and a protective shell 60. The front and left sides of the L-shaped connecting plate 2 are provided with a locking assembly for locking the wall panel 3, an unlocking assembly for unlocking the locking assembly and a protective shell 60. The front and left sides of the L-shaped connecting plate 2 are fixed with the protective shell 60 by bolts. The protective shell 60 is a shell close to the L-shaped connecting plate and the lower end opening. The locking assembly and the unlocking assembly are both located on the inner side of the protective shell 60.

[0020] like Figure 2 and Figure 3As shown, the unlocking assembly includes a fixing seat 41, a rack 42, a stud 43, a gear 44 and a mounting plate 45. Since the front side and the left side of the L-shaped connecting plate 2 are both provided with locking assemblies for locking the wall panel 3, and the locking assemblies at the two locations are the same, the locking assembly located on the front side of the L-shaped connecting plate 2 is described as an example. Two fixing seats 41 are welded and fixed at intervals on the front side of the L-shaped connecting plate 2, and a rack 42 is slidably connected between the two fixing seats 41. Two studs 43 are embedded and rotatably connected at intervals on the front side of the L-shaped connecting plate 2. The two studs 43 are fixedly connected with gears 44 on one side close to the L-shaped connecting plate 2. The rack 42 is only provided with spur teeth at a position close to the two gears 44, and the gear 44 and the rack 42 are meshed with each other. The two studs 43 are threadedly connected with a mounting plate 45 on the side away from the L-shaped connecting plate 2. The rack 42 is not sufficient to drive the gear 44 to rotate under the action of its own gravity.

[0021] like Figure 2 , Figure 3 and Figure 4 As shown, the locking assembly includes a sliding cylinder 51, a trapezoidal limit block 52 and a compression spring a53. The sliding cylinder 51 is symmetrically welded and fixed on the side wall of the mounting plate 45 close to the L-shaped connecting plate 2. The rear side of the sliding cylinder 51 can penetrate the L-shaped connecting plate 2 and just contact with its inner cavity. Trapezoidal limit blocks 52 are slidably arranged in the sliding cylinder 51. The side of the trapezoidal limit blocks 52 away from the mounting plate 45 is provided with an inclined surface, and the wall panel 3 can retract the trapezoidal limit blocks 52 into the sliding cylinder 51 by squeezing the inclined surface. Two compression springs a53 are connected between the trapezoidal limit blocks 52 and the adjacent mounting plates 45. Trapezoidal card grooves 54 are provided on the surface of the wall panel 3 corresponding to the trapezoidal limit blocks 52, and the trapezoidal limit blocks 52 can be inserted into the trapezoidal card grooves 54.

[0022] First, the staff slides the two wall panels 3 into the cavity in the middle of the L-shaped connecting plate 2 respectively. In the process of the wall panel 3 sliding toward the inside of the L-shaped connecting plate 2, the edge of the wall panel 3 contacts the inclined surface of the trapezoidal limit block 52. As the wall panel 3 continues to slide, the trapezoidal limit block 52 is lifted up and retracted into the sliding cylinder 51. At this time, the compression spring a53 is gradually compressed. When the trapezoidal groove 54 set on the wall panel 3 slides to the position corresponding to the trapezoidal limit block 52, under the resetting action of the compression spring a53, the trapezoidal limit block 52 extends out from the inside of the sliding cylinder 51 again and is stuck in the trapezoidal groove 54, thereby locking and limiting the wall panel 3. In this way, the connection of the wall panel 3 is completed, and there is no need to support and adjust the wall panel 3, which saves time and effort. When the wall panel 3 needs to be removed, When the rack 42 moves downward, the stud 43 is driven to rotate by cooperating with the gear 44, thereby moving the mounting plate 45 away from the L-shaped connecting plate 2. In this way, the sliding cylinder 51 will slide outward, causing the trapezoidal limit block 52 to disengage from the trapezoidal slot 54, thereby releasing the locking limit of the wall panel 3. At this time, the wall panel 3 can be pulled out of the cavity in the middle of the L-shaped connecting plate 2. After pulling out the wall panel 3, the staff will push the rack 42 upward to reset the mounting plate 45, the sliding cylinder 51 and the trapezoidal limit block 52, so as to install the wall panel 3 next time. During use, the protective shell 60 will surround the stud 43, the gear 44 and the rack 42 and other components inside it, thereby preventing these components from being damaged by sun and rain.

[0023] like Figure 2 As shown, an L-shaped connecting rod 6 and a pedal 61 are also included. The L-shaped connecting rod 6 is welded and fixed between the lower ends of the two racks 42, and the pedal 61 is welded and fixed in the middle of the L-shaped connecting rod 6.

[0024] By providing the L-shaped connecting rod 6 and the pedal 61, when the wall panel 3 needs to be removed from the L-shaped connecting plate 2, the staff can step on the pedal 61 to pull the two racks 42 downward at the same time. In this way, the staff does not need to bend down to operate the two racks 42 separately, which saves time and effort.

[0025] like Figure 2 and Figure 4 As shown, it also includes a sliding plate 7 and a compression spring b71. The sliding plates 7 are slidably arranged on the right side and the rear side of the internal cavity of the L-shaped connecting plate 2. A plurality of compression springs b71 are connected to the inner side walls of the two sliding plates 7 and the L-shaped connecting plate 2 in an upper and lower interval manner. The compression springs b71 respectively connected to the two sliding plates 7 are staggered, so that the compression springs b71 will not affect each other.

[0026] By setting the sliding plate 7 and the compression spring b71, when the wall panel 3 is not installed in the L-shaped connecting plate 2, the compression spring b71 is in a naturally straightened state. At this time, the two sliding plates 7 are respectively located at the position where the cavity in the middle of the L-shaped connecting plate 2 is connected to the external environment (such as Figure 2 As shown), the cavity in the middle of the L-shaped connecting plate 2 can be closed to prevent external debris from entering. When the wall panel 3 is installed, the wall panel 3 will push the sliding plate 7 to compress the compression spring b71. When the wall panel 3 is removed, the two sliding plates 7 will also be reset respectively under the reset action of the compression spring b71.

[0027] like Figure 2 As shown, a sealing plate 8 is also included, and the sealing plate 8 is welded and fixed to the lower part of the rack 42.

[0028] By providing the sealing plate 8 , the lower end opening of the protective shell 60 can be sealed to prevent foreign matter from entering the interior of the protective shell 60 .

[0029] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
