Description

Technical Field

[0001] This utility model relates to the field of concealed handle technology, specifically a concealed handle with a self-locking structure for mobile modular housing. Background Technology

[0002] Prefabricated container houses are a new concept of environmentally friendly and economical mobile homes, using light steel frames, sandwich panels as enclosure materials, and standardized modular series for spatial assembly. The components are connected by bolts. Originating in the United States, their roots can be traced back to early automobile and electric road travel, stemming from travel trailers. These houses emerged to meet the need for mobility.

[0003] Currently, most mobile container houses use protruding handles, but these protruding handles are prone to colliding with the side of the container, causing damage to the surface of the container and deformation of the handles. They are also prone to damage during handling and transportation. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a concealed handle with a self-locking structure for mobile container houses, thereby solving the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a concealed handle with a self-locking structure for a mobile container house. A movable seat is fixedly installed on the inner side of the outer shell. A main shaft is movably installed on the inner side of the movable seat. A pressing plate is fixedly installed on the front of the main shaft. A movable ring is sleeved on the outer side of the main shaft. A limiting ring is fixedly installed on the outer side of the main shaft behind the movable ring. A fixing ring is fixedly installed on the outer side of the main shaft behind the limiting ring. An unlocking block is sleeved on the rear side of the fixing ring on the outer side of the main shaft. A fixing block is fixedly installed on the rear side of the main shaft. A fixing seat is provided on the outer side of the fixing block. A telescopic rod is fixedly installed on the inner side of the fixing seat. A locking block is fixedly installed at the telescopic end of the telescopic rod. A spring is fixedly installed on the outer side of the telescopic rod.

[0008] Preferably, the front side of the outer casing has a groove.

[0009] Preferably, the movable seat has a fixing groove on its front side and a limiting groove on its rear side.

[0010] Preferably, the front of the fixing seat is provided with a locking groove, and the top surface of the locking groove is provided with a telescopic rod groove.

[0011] Preferably, the rear side of the unlocking block is provided with a slope, and the front side of the unlocking block is provided with a through hole.

[0012] Preferably, the front side of the fixing block is provided with a concave surface.

[0013] Compared with the prior art, this utility model provides a concealed handle with a self-locking structure for mobile container houses, which has the following advantages:

[0014] 1. This mobile container uses a concealed handle with a self-locking structure. First, the movable base is installed inside the door, and the fixed base is installed on the door frame. When the door is pushed, the fixed block may first extend into the lock groove. When the locking block contacts the curved surface on the back of the fixed block, it will retract upwards, and the spring will also retract at the same time. After the fixed block extends to a certain depth, the locking block will pop out and lock the fixed block. The spring will pop out. When it is necessary to unlock the door, insert your finger into the inside of the outer shell and press the button. At this time, the button will push the main shaft backwards. The fixed groove prevents the movable ring from moving to the rear side, and the limiting groove can limit the displacement distance of the limiting ring to avoid excessive movement that will prevent unlocking.

[0015] 2. This mobile container uses a concealed handle with a self-locking structure. After being pushed a certain distance, the rear side of the limiting ring will contact the rear side of the limiting groove, at which point it cannot be pushed further back. The bottom surface of the locking block will slide across the inclined surface, causing the rear side of the locking block to contact the front of the unlocking block. After releasing the button, the locking groove is pulled outwards, and the locking block will retract upwards along the front surface of the unlocking block and slide over the surfaces of the unlocking block and the fixed block before popping downwards to reset, completing the unlocking process. The lock groove allows the fixed block to contact the locking block and be locked, completing the door's self-locking process. The telescopic rod groove provides sufficient space for the telescopic rod to extend and retract, completing both unlocking and self-locking. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-2 As shown, this utility model provides a technical solution: a concealed handle with a self-locking structure for a mobile container. A movable base 2 is fixedly installed on the inner side of the outer shell 1. A main shaft 3 is movably installed on the inner side of the movable base 2. A pressing plate 4 is fixedly installed on the front of the main shaft 3. A movable ring 5 is sleeved on the outer side of the main shaft 3. A limiting ring 6 is fixedly installed on the outer side of the main shaft 3 behind the movable ring 5. A fixing ring 7 is fixedly installed on the outer side of the main shaft 3 behind the limiting ring 6. An unlocking block 8 is sleeved on the rear side of the fixing ring 7 on the outer side of the main shaft 3. A fixing block 9 is fixedly installed on the rear side of the main shaft 3. A fixing base 10 is provided on the outer side of the fixing block 9. A telescopic rod 11 is fixedly installed on the inner side of the fixing base 10. A locking block 12 is fixedly installed on the telescopic end of the telescopic rod 11. A spring 13 is fixedly installed on the outer side of the telescopic rod 11.

[0021] Furthermore, a groove 101 is provided on the front side of the outer casing 1.

[0022] With the above technical solution, when the groove 101 is in use, the user can easily open the door after pressing the button 4 to unlock it.

[0023] Furthermore, a fixing groove 201 is provided on the front of the movable seat 2, and a limiting groove 202 is provided on the rear side of the fixing groove 201.

[0024] Through the above technical solution, the fixed groove 201 prevents the movable ring 5 from moving to the rear side, and the limiting groove 202 can limit the displacement distance of the limiting ring 6, avoiding excessive movement that would prevent unlocking.

[0025] Furthermore, a locking groove 1001 is provided on the front side of the fixing base 10, and a telescopic rod groove 1002 is provided on the top surface of the locking groove 1001.

[0026] Through the above technical solution, the lock groove 1001 allows the fixing block 9 to contact the lock block 12 and be locked to complete the door's self-locking process, and the telescopic rod groove 1002 allows the telescopic rod 11 to have enough space to extend and retract to complete unlocking and self-locking.

[0027] Furthermore, the rear side of the unlocking block 8 is provided with a bevel 801, and the front side of the unlocking block 8 is provided with a perforation 802.

[0028] Through the above technical solution, the inclined surface 801 allows the locking block 12 to move upward after contacting the unlocking block 8, and the locking block 9 is released through the front of the unlocking block 8 to complete the unlocking.

[0029] Furthermore, the front side of the fixing block 9 is provided with a concave surface 901.

[0030] Through the above technical solution, the concave surface 901 can fit against the surface of the inclined surface 801, so that the unlocking block 8 will not slide when it is released from the fixing block 9.

[0031] Working principle: The movable seat 2 is installed inside the door, and the fixed seat 10 is installed on the door frame. When the door is pushed, the fixed block 9 first extends into the lock groove 1001. When the locking block 12 contacts the curved surface on the rear side of the fixed block 9, it will retract upwards. At the same time, the spring 13 will also retract. After the fixed block 9 extends to a certain depth, the locking block 12 will pop out and lock the fixed block 9. The spring 13 will then pop out. When it is necessary to unlock the door, insert your finger into the inside of the outer casing 1 and press the button 4. Plate 4 will push the spindle 3 backward. After being pushed a certain distance, the rear side of the limiting ring 6 will contact the rear side of the limiting groove 202. At this point, it can no longer be pushed backward. The bottom surface of the locking block 12 will slide across the inclined surface 801, so that the rear side of the locking block 12 contacts the front side of the unlocking block 8. After releasing the pressing plate 4, it will be pulled outward by holding the groove 101. The locking block 12 will retract upward along the front surface of the unlocking block 8 and slide across the surface of the unlocking block 8 and the fixing block 9 before popping downward to reset, thus completing the unlocking.
