The invention relates to the technical field of door latch devices, and discloses a
latch for latching a tempered glass door for swimming pools.
With the continuous improvement of people's living standards, swimming pools
become more and more popular in people's lives as places of amusement and recreation.
In the prior art, tempered glass doors surrounding a swimming pool are usually arranged
around the swimming pool. Without affecting the appearance, the tempered glass doors
can prevent small animals or children from accidentally entering the swimming pool,
or some flying objects, such as footballs, from flying into the swimming pool to result
in danger. In the prior art, among the tempered glass doors surrounding the swimming
pool, there is usually a tempered glass door that is movable so that the personnel can
walk in or out from this door. Latches such as glass latches and locks may be arranged
on this movable tempered glass door, by which this tempered glass door can be latched
with the tempered glass doors beside it, to realize opening or closing. There are two
kinds of such latches in the prior art: latches with a locking structure and latches without
a locking structure. The latches with a locking structure are complex in structure and
difficult to detach, and their lock cylinders are usually made of metal. In spite of
compactness and good fixation effect, a mating key is required for unlocking. It is very
difficult to unlock the latch if the key is accidentally lost. Thus, they are not convenient
to use. In spite of convenient use, the latches without a locking structure can prevent
only children who did not develop intellectually from entering the swimming pool.
Fasteners, such as pins, are unable to prevent children, who have developed
intellectually to some extent, for example, those just in elementary schools, from
entering the swimming pool, because the children can enter the swimming pool by pulling the pin in a correct direction. Thus, there are still some potential problems when such locks are used.
Accordingly, the invention provides a latch for latching a tempered glass door for swimming pools.
To solve the above technical problems, the invention employs the following technical solution. A latch for latching a tempered glass door for swimming pools is
provided, comprising a first latch and a second latch, wherein the first latch comprises
a first latch plate, a second latch plate, and a connecting screw that connects the first latch plate and the second latch plate together, with a spacing reserved between the first
latch plate and the second latch plate for mounting a tempered glass door; a first holding
portion is arranged on the sidewall of a side of the first latch plate, and a connecting column having a circular cross section is arranged on a top surface of the first holding
portion, with one end of the connecting column running into the first holding portion
downward and vertically and the other end of the connecting column extending from
the top surface of the first holding portion upward and vertically; a sealing cover, a lock cylinder, a lock block and a magnetic column are successively and downward arranged
in the connecting column, the sealing cover is arranged at a top end of the connecting
column by interference fit, and a through hole is formed on the sealing cover; the lock cylinder is movably connected in the connecting column, a hexagonal blind hole is
formed on a top surface of the lock cylinder, and a meshing gear is arranged on a bottom
surface of the lock cylinder; the lock block is movably connected in the connecting column, a meshing slot is formed on the lock block, and the meshing slot is meshed
with the meshing gear; the magnetic column is movably connected in the connecting
column, a first stopper is arranged at an end of the magnetic column close to the side of the lock block, and the other end of the magnetic column runs through the connecting
column vertically and downward and out of the first holding portion; the second latch has an h-shaped cross section, a second holding portion is arranged on the sidewall of
a long side of the second latch, a first stopping slot is formed on a top surface of the second holding portion, and magnetic material is coated in the first stopping slot. Preferably, the through hole is arranged concentrically to the hexagonal blind hole, and the through hole has a shape greater than that of the hexagonal blind hole. Preferably, the connecting column is in sliding connection to a first holding block.
Preferably, a second stopper is arranged on an outer wall of the lock cylinder, a third stopper is arranged on an inner wall of the connecting column, and the second
stopper and the third stopper are fitted in position. Preferably, a second stopping slot is formed on an inner wall of the connecting
column, and the second stopping slot has a shape and a size matched with those of the
lock block. Preferably, a first stopping step is formed on the inner wall of the connecting
column, the first stopping step is arranged on the bottom of the lock block, and the
surface of the first stopping step is in sliding connection to the bottom surface of the lock block.
Preferably, a second stopping step is formed on the inner wall of the connecting
column, at a position close to the bottom end, and the second stopping step has, in its
middle, a linear distance less than the diameter of the first stopper. Preferably, the connecting column, the sealing cover, the lock cylinder and the lock
block are all made of plastic material.
Preferably, a spring, one end of which is fixedly connected to the first stopper and the other end is fixedly connected to the bottom of the connecting column, is sheathed
on the magnetic column.
Compared with the prior art, the invention has the following advantages: 1. In the invention, a through hole is formed on the sealing cover and a hexagonal
blind hole is formed on the top surface of the lock cylinder. By inserting the mating key
into the hexagonal blind hole from the through hole and rotating the key, the lock cylinder is rotated. The lock block starts sliding, for the purpose of locking or unlocking.
When the key is lost, due to better adaptability of the hexagonal blind hole compared with the metal keyhole in the prior art, a hexagonal tool, for example a hex key, can be
inserted into the hexagonal blind hole for the purpose of unlocking. Furthermore, the sealing cover is arranged in the connecting column by interference fit. Therefore, when there is no hexagonal tool, a small tool, for example a screwdriver, can be used. In this case, the screw rod is inserted into the through hole to remove the sealing cover, and then the lock cylinder is taken out. In this way, the lock can be detached to open the tempered glass door of the swimming pool. Meanwhile, the aforementioned tools are tools that are difficult for children to obtain. Thus, it is ensured that the tempered glass doors can be used normally, but cannot be opened by children easily. Compared with the latches with a locking structure in the prior art, the latch provided in the invention has the advantages of simple structure and convenient use.
2. In the utility mode, a magnetic column, a first stopping slot, a lock cylinder, a lock block and a second stopping slot are arranged. The magnetic column can, when
magnetically attracted, run into the first stopping slot. The first stopping slot can prevent
the magnetic column from moving up and down. Then, the lock cylinder is rotated so that the lock block can run into the second stopping slot. In this way, the back-and-forth
movement of the connecting column is stopped. It is thus ensured that it is difficult to
pull out the connecting column outward from the first holding portion, and further
ensured that the magnetic column will not be pulled out because the connecting column is pulled out. Accordingly, this ensures the tightness between the tempered glass doors
of the swimming pool. The children are well prevented from bringing themselves in
danger by entering the swimming pool after damaging the latch, due to the poor tightness between the tempered glass doors of the swimming pool.

The second latch (2) has an h-shaped cross section. During the mounting, the first latch 1 is mounted on a movable tempered glass door of the swimming pool, and the second latch 2 is inserted to a fixed tempered glass door of the swimming pool.
A first holding portion (3) is arranged on a sidewall of a side of the first latch plate (100) in the first latch 1. The first holding portion (3) is convenient for an operator to
hold the first latch 1. In this embodiment, the first holding portion 3 is made of plastic material whose surface is frosted to ensure it is less likely to slip from the hand when
the operator holds the first latch. A connecting column (4) having a circular cross
section is arranged on a top surface of the first holding portion (3), and the bottom of the connecting column 4 is enclosed. One end of the connecting column (4) runs into
the first holding portion (3) downward and vertically and the other end of the
connecting column (4) extends from the top surface of the first holding portion (3) upward and vertically. The connecting column 4 is in sliding connection to the first
holding portion 3, so that the connecting column 4 can vertically move up and down on
the first holding portion 3. A sealing cover (5), a lock cylinder (6), a lock block (7) and
a magnetic column (8) are successively and downward arranged in the connecting column (4), the sealing cover (5) is arranged at a top end of the connecting column (4)
by interference fit, and a through hole (9) is formed on the sealing cover (5). The lock
cylinder (6) is movably connected in the connecting column (4). A hexagonal blind hole (10) is formed on a top surface of the lock cylinder (6). The hexagonal blind hole (10)
is arranged concentrically to the through hole (9), and the hexagonal blind hole (10) has
a shape less than that of the through hole (9). A meshing gear (11) is arranged on a bottom surface of the lock cylinder (6). The lock block (7) is movably connected in the
connecting column (4), a meshing slot (12) is formed on the lock block (7), and the
meshing slot (12) is meshed with the meshing gear (11). When the latch cylinder 6 is rotated, the lock block 7 moves back and forth. The magnetic column (8) is movably
connected in the connecting column (4), a first stopper (13) is arranged at an end of the magnetic column (8) close to the side of the lock block (7), and the other end of the
magnetic column (8) runs through the connecting column (4) vertically and downward and out of the first holding portion (3). A spring (21), one end of which is fixedly connected to the first stopper (13) and the other end is fixedly connected to the bottom of the connecting column (4), is sheathed on the magnetic column (8). By the spring 21, the magnetic column 8 can be retracted automatically, and it is thus convenient to use.
A second holding portion 14 is arranged on the sidewall of a long side of the second latch 2, a first stopping slot 15 is formed on a top surface of the second holding portion
14, and magnetic material is coated in the first stopping slot 15. The position of the first stopping slot 15 enables the magnetic column 8 running out of the first holding portion
3 can be inserted into the first stopping slot 15.
A third stopper (17) is arranged on an inner wall of the connecting column (4), a second stopper (16) is arranged on an outer wall of the lock cylinder (6), and the second
stopper (16) and the third stopper (17) are fitted in position. The fitting of the second
stopper (16) and the third stopper (17) can limit the rotation angle of the lock cylinder 6 in the connecting column 4. A second stopping slot (18) is formed on an inner wall of
the connecting column (4), and the second stopping slot (18) has a shape and a size
matched with those of the lock block (7). A first stopping step (19) is formed on the
inner wall of the connecting column (4), the first stopping step (19) is arranged on the bottom of the lock block (7), and the surface of the first stopping step (19) is in sliding
connection to the bottom surface of the lock block (7). The first stopping step (19) is
used to support the lock block 7. A second stopping step (20) is formed on the inner wall of the connecting column (4), at a position close to the bottom end, and the second
stopping step (20) has, in its middle, a linear distance less than the diameter of the first
stopper (13). The second stopping step (20) is used to limit the travel of the magnetic column 8.
The connecting column (4), the sealing cover (5), the lock cylinder (6) and the
lock block (7) are all made of plastic material. Making them of plastic material can reduce the cost, and is also more convenient to detach them.
When in use of the latch of the invention, the first latch 1 and the second latch 2 are mounted on a proper tempered glass door for a swimming pool, respectively. The
first latch 1 and the second latch 2 are adjusted in distance and position, so that the magnetic column 8 can be inserted into the first stopping slot 15 when being attracted by the magnetic material coated in the first stopping slot 15, and it is ensured that the spring 21 is in the compressed state. Then, the key m is inserted into the through hole 9. The key m is inserted into the hexagonal blind hole 10 from the through hole 9. Then, the key m is turned. The lock cylinder 6 starts rotating, so that the lock block 7 slides on the first stopping step 19 and the lock block 7 is inserted into the second stopping slot 18. At this moment, the tempered glass door for the swimming pool is locked by the lock of the invention, and the connecting column 4 cannot be pulled out due to the lock block 7 and the second stopping slot 18. When it is required to unlock the lock, the key m is inserted into the hexagonal blind hole 10 from the through hole 9. Then, the key m is turned. The lock cylinder 6 starts rotating, so that the lock block 7 slides on the first stopping step 19 and the lock block 7 is removed from the second stopping slot
18. At this moment, the connecting column 4 is pulled outward, the connecting column 4 moves outward, and the first stopping step 19 moves together. The first stopping step
19 can get the first stopper 13 stuck, to drive the first stopper 13 to move together, in
order to enable the magnetic column 8 to move together. The magnetic column 8 comes
out of the first stopping slot 15 due to an external force and the elasticity of the spring 21. At this moment, the tempered glass door for the swimming pool is unlocked by the
lock of the invention.
