Abstract
Description
Technical Field
[0001] This application relates to the field of lock technology, and more particularly to door locks and housings. Background Technology
[0002] In some factories, automated devices, such as robotic arms, are housed within enclosures. These enclosures have operable doors that allow personnel to enter the enclosure if the automated devices malfunction. For safety reasons, the door must remain open once a person is inside, allowing for easy exit.
[0003] In existing technology, door locks are usually located in the middle of the door and generally require drilling holes in the door for installation.
[0004] However, in some scenarios, the door is made of glass, making it impossible to drill holes in the door, which prevents the installation of door locks that require drilling in the existing technology. Utility Model Content
[0005] This application provides a door lock and a housing to solve the technical problem in the prior art that a hole needs to be drilled in the door to install the door lock.
[0006] In a first aspect, the door lock provided in this application is used to lock or unlock a door of a housing, the door lock comprising:
[0007] A fixing seat is configured to be fixedly disposed at the bottom of the housing of the outer casing, the fixing seat having a longitudinally extending guide portion and a longitudinally extending through hole formed thereon;
[0008] A foot pedal having a connecting groove, the foot pedal being vertically and flexibly mounted on the guide portion via the connecting groove;
[0009] A shaft, connected to the foot pedal and passing through the through hole; and
[0010] An elastic element is connected to the shaft to apply an upward force to the shaft;
[0011] The door lock has a locked state and an unlocked state.
[0012] When the door lock is in the locked state, the upper end of the shaft extends out from the upper end of the through hole under the action of the elastic element and is located in the locked position. In the locked position, the upper end of the shaft is higher than the lower edge of the door.
[0013] When the door lock is in the unlocked state, the upper end of the shaft moves downward under the action of the foot pedal, descending from the locked position to the unlocked position. In the unlocked position, the upper end of the shaft is lower than the edge of the door.
[0014] Secondly, the casing provided in this application includes:
[0015] case;
[0016] A door, movably mounted on the housing, having a lock hole at its lower edge; and
[0017] The door lock described in the first aspect is disposed at the bottom of the housing, and the upper end of the shaft can extend into the lock hole or be separated from the lock hole.
[0018] Compared with the prior art, this application includes at least the following beneficial effects:
[0019] The mounting base is located at the bottom of the housing, placing the lock at the bottom of the housing rather than on the door, thus eliminating the need for drilling holes in the door. Furthermore, the lock's state can be changed by foot, for example, switching from locked to unlocked, and a spring-loaded element can reset the lock, switching it back from unlocked to locked. When the door is in the open position and the foot leaves the foot pedal, the upper end of the pivot is higher than the lower edge of the door, preventing the door from moving from the open to the closed position, ensuring the door remains open and guaranteeing personal safety.

[0031] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0032] like Figure 1 and Figure 2 As shown, the outer casing includes a housing 10 and a door 20. The housing 10 is typically located on the ground. The door 20 is movably mounted on the housing 10, for example, the door 20 is rotatably or translationally mounted on the housing 10. The number of doors 20 is not limited; there can be one, two, or more. Figure 1 The image shows two rotatable ground doors 20.
[0033] like Figure 1 and Figure 2As shown, the housing also includes a door lock 30. Unlike the door lock 30 in the prior art that is mounted on the door 20, the door lock 30 in this embodiment is located at the bottom of the housing 10, that is, the door lock 30 is not mounted on the door 20, so it is not necessary to drill holes in the door 20 to install the door lock 30. Therefore, even a door 20 made of glass can be fitted with the door lock 30 of this embodiment. However, this does not preclude the installation of the door lock 30 of this embodiment on a door 20 made of other materials.
[0034] like Figure 2 As shown, a lock hole 21 is provided on the lower edge of the door 20. The door lock 30 can be inserted into the lock hole 21 to lock the door 20 in the closed position. In addition, the door lock 30 can be separated from the lock hole 21, so that the door 20 can be moved from the closed position to the open position.
[0035] like Figure 3 and Figure 4 As shown, the door lock 30 includes a fixed base 31, a foot pedal 32, a shaft 33, and a resilient element 34. The fixed base 31 is fixedly disposed at the bottom of the housing 10 (see Figure 10). Figure 2 The fixed base 31 has a longitudinally extending guide portion 311, and the foot pedal 32 is vertically and flexibly mounted on the guide portion 311 via a connecting groove 321. Furthermore, as... Figure 4 As shown, a longitudinally extending through hole 312 is provided on the guide portion 311, and the shaft 33 passes through the through hole 312 to allow it to move up and down within the through hole 312. Furthermore, the shaft 33 is connected to the foot pedal 32. When the foot pedal 32 moves downward (for example, when a person's foot is on the foot pedal 32), the foot pedal 32 can drive the shaft 33 to move downward synchronously. Additionally, an elastic element 34 is connected to the shaft 33 to apply an upward force to the shaft 33 so that after the person's foot leaves the foot pedal 32, the shaft 33 is driven to move upward.
[0036] The door lock 30 of this application embodiment has a locked state and an unlocked state.
[0037] Figure 2 A schematic diagram is shown where the door lock 30 is in the locked state. (As shown) Figure 2 As shown, when the door lock 30 is in the locked state, the upper end of the shaft 33 extends out from the upper end of the through hole 312 under the action of the elastic element 34, and the upper end of the shaft 33 extends into the lock hole 21, locking the door 20 in the closed position. In this embodiment, the position of the upper end of the shaft 33 when the door lock 30 is in the locked state is defined as the locked position, such as... Figure 2As shown, in the locked position, the upper end of shaft 33 extends into the lock hole 21, meaning the upper end of shaft 33 is higher than the lower edge of door 20. Therefore, if door 20 is in the closed position and door lock 30 is in the locked state, door 20 is locked in the closed position by door lock 30; if door 20 is in the open position and door lock 30 is in the locked state, the lower edge of door 20 is lower than the upper end of shaft 33, and door 20 cannot pass over shaft 33 to enter the closed position, meaning door 20 can only be in the open position.
[0038] When the door lock 30 is in the unlocked state, the upper end of the shaft 33 moves downward under the action of the foot pedal 32, descending from the locked position to the unlocked position. In the unlocked position, the upper end of the shaft 33 is lower than the edge of the door 20. Therefore, there is no interference between the door 20 and the shaft 33, and the door 20 can move freely between the closed and open positions.
[0039] In summary, the door lock 30 of this application embodiment is located at the bottom of the housing 10. The state of the door lock 30 can be changed by stepping on it, for example, switching from the locked state to the unlocked state. The door lock 30 can also be reset by the elastic element 34, that is, switching back from the unlocked state to the locked state.
[0040] like Figure 3 and Figure 4 As shown, the guide portion 311 includes a plate 3111 and a cylindrical body 3112 connected to the plate 3111, with a through hole 312 located in the cylindrical body 3112. Corresponding to the guide portion 311, the connecting groove 321 includes a first groove 3211 connected to the plate 3111 and a second groove 3212 connected to the cylindrical body 3112. When the foot pedal 32 moves up and down, the first groove 3211 and the plate 3111, as well as the second groove 3212 and the cylindrical body 3112, move up and down synchronously. Furthermore, as... Figure 4 As shown, the first groove 3211 is a strip-shaped groove, which fits the plate 3111. The second groove 3212 is a circular groove, which fits the cylinder 3112. This ensures good guiding effect between the guide part 311 and the connecting groove 321.
[0041] like Figure 3 As shown, the foot pedal 32 is located on the side near the fixed base 31. Figure 3 The left side of the middle section is provided with a longitudinally extending first guide block 322 and a second guide block 323 (see...). Figure 1 The first guide block 322 is disposed on the first side of the guide portion 311, and the second guide block 323 is disposed on the second side of the guide portion 311 opposite to the first side. By providing the first guide block 322 and the second guide block 323, the length of the connecting groove 321 is further increased, so that the foot pedal 32 and the guide portion 311 have a better guiding effect.
[0042] like Figure 4 As shown, the mounting base 31 includes a first substrate 313 and a second substrate 314. The second substrate 314 and the first substrate 313 are separately formed, meaning that the first substrate 313 and the second substrate 314 are first processed and formed separately, and then connected together to form the mounting base 31. The first substrate 313 is fixedly disposed at the bottom of the housing 10, and the plate 3111 mentioned above is a part of the substrate. The second substrate 314 is fixedly disposed on the plate 3111, and the cylindrical body 3112 mentioned above is a part of the second substrate 314. By dividing the mounting base 31 into the first substrate 313 and the second substrate 314, it is beneficial to the processing and manufacturing of the mounting base 31 and reduces processing costs.
[0043] like Figure 3 and Figure 4 As shown, a first connector 331 is provided at the lower end of the shaft 33. The first connector 331 is located below the foot pedal 32. The size of the first connector 331 is larger than the size of the connecting groove 321 so that the first connector 331 can abut against the lower surface of the foot pedal. As an example, the first connector 331 can be a protrusion provided at the lower end of the shaft 33.
[0044] Alternatively, the lower end of shaft 33 can be fixedly connected to foot pedal 32, for example, by welding the lower end of shaft 33 to foot pedal 32. In this way, foot pedal 32 can also drive shaft 33 to move downward.
[0045] like Figure 3 and Figure 4 As shown in the embodiment of this application, the elastic element 34 is a spring, and the spring is sleeved in the middle of the shaft 33.
[0046] Furthermore, such as Figure 3 As shown, in order to fix the spring, the guide part 311 is provided with a first connecting surface, the middle part of the shaft 33 is provided with a second connecting surface, the lower end of the spring abuts against the first connecting surface, and the upper end of the spring abuts against the second connecting surface.
[0047] As an example of the first connecting surface, such as Figure 3 As shown, the guide portion 311 has two cylindrical bodies 3112 arranged vertically and horizontally, and the first connecting surface is the upper surface of the lower cylindrical body 3112.
[0048] As an example of the second connecting surface, such as Figure 3 As shown, a second connector 332 is fixedly installed in the middle of the shaft 33, and the lower surface of the second connector 332 is the second connecting surface.
[0049] Although this application has been described in detail above with general descriptions, specific embodiments, and experiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this application fall within the scope of protection claimed in this application.
