Description

Technology Field

[0001] The present invention relates to a multi-water lock clamp equipped with a torsion spring, and more specifically, to a technology that allows firefighters to quickly and conveniently connect a nozzle and a fire hose by pressurizing the outer side of the fire hose when extension is required during firefighting operations, thereby restricting the movement of water or firefighting agent inside the fire hose, and ensuring that the fire hose remains fixed and does not detach outward from its position when pressurized. Background Technology

[0002] Typically, when suppressing a fire, a fire hose connected to a fire hydrant or fire truck is used; in this case, a nozzle must be connected to the fire hose.

[0003] Meanwhile, in the process of connecting the nozzle and the hose, if water or fire extinguishing agent is not moving through the fire hose, the fire hose and the nozzle can be easily connected.

[0004] However, when water or fire extinguishing agent is moving through the fire hose, a firefighter or other worker stops the operation of the fire hydrant pump or the vehicle motor, connects a nozzle to the fire hose, and restarts the pump or motor for use.

[0005] This conventional method requires a lot of labor and takes a very long time at fire suppression sites where every second counts. However, by using a clamp that pressurizes the outside of the fire hose to restrict the movement of water or fire extinguishing agent, it has the advantage of allowing firefighters or workers to use it without the hassle of stopping the pump or motor.

[0007] First, if we look at conventional technology,

[0008] This is a technology relating to a fire hose clamp registered under registration number 20-0081482 (actual), comprising a fixed body connected to a central axis, a movable body connected to a connecting axis, a handle connected to the upper side of a fixed member fixed to the fixed body via a central bolt to allow for easy rotation, a release piece having a toothed locking mechanism formed on the front of the middle part of the movable body connected to a fixed axis to allow for easy rotation, a spring that supports the release piece between the release piece and the movable body, and a locking piece of the handle connected to the toothed locking mechanism of the release piece to enable the clamping and unlocking of the movable body.

[0009] The aforementioned conventional technology has a problem in that, when pressurizing a hose, it is configured with a structure in which one side is not wrapped rather than completely enclosing the hose, so the hose may detach from the clamp due to external factors such as impact to the clamp or pressure of the hose during operation.

[0010] If the above hose detaches from the clamp, water is discharged by the force transmitted from the pump or motor, which can lead to water being wasted or cause safety accidents of varying severity. The problem to be solved

[0011] The present invention was devised to solve the problems of the aforementioned conventional technology. It focuses on providing a multi-water lock clamp equipped with a torsion spring that prevents the fire hose from detaching by completely wrapping and pressurizing the outer surface of the hose to temporarily block the movement of water inside the fire hose without stopping the operation of the pump or motor when connecting a nozzle to the fire hose. It also includes an additional fixing means to prevent the clamp's pressure from releasing due to the water pressure, and ensures that the fire hose can be connected while remaining fixed without detaching from the outside of the clamp when pressurizing the fire hose, thereby enabling stable operation and convenience. means of solving the problem

It is configured with a locking member (40) having one side connected to the second hinge shaft (13) and the other side having a fourth hinge shaft (41) formed thereon to engage with the locking groove (23); so that when the second handle bar (20) is unfolded outward, a space (g) is formed between the first handle bar (10) and the connecting bar (30), and a fire hose (h) is positioned therein, so that when the second handle bar (20) is restored to its original state, the first handle bar (10) and the connecting bar (30) press the outside of the fire hose (h) to restrict the movement of water or fire extinguishing agent, and on the other side of the first and second handle bars (10, 20) where the locking member (40) is configured, so that the first and second handle bars (10, 20) are fixed without spreading apart while the fire hose (h) is pressed. A fixing means (50) in the shape of a U is configured, and a locking projection (15, 25) is formed on the outer side of each of the first and second handle bars (10, 20), and both sides of the fixing means (50) are fixed by being caught on the locking projections (15, 25), and a gap (y) is provided so that the fire hose (h) is not short-circuited when a fire hose (h) is positioned between the first handle bar (10) and the connecting bar (30) and pressurized, and the fire hose (h) is provided with a gap (y) so that the fire hose (h) is not short-circuited, and the fourth hinge shaft (41) of the locking member (40) is configured to rotate in place so as to minimize friction when sequentially engaging the outer part of the second handle bar (20) and the inner side of the locking groove (23), and a guide groove (33) is formed in the longitudinal direction on the upper side of the connecting bar (30), and on the lower side of the second handle bar (20) the A protruding guide (26) corresponding to a guide groove (33) is formed, and when a fire hose (h) is positioned in the space (g) and pressurized, the protruding guide (26) is fitted into the guide groove (33) to prevent twisting of the clamp. A torsion spring in-in groove (12) is formed on one side of the first handle bar (10), and a fixed shaft (14) is formed that is positioned in the torsion spring in-in groove (12) and extends to the inner side of the first handle bar (10). One side of the torsion spring (17) is fitted with the fixed shaft (14) so ​​that when the water lock clamp is in a folded state, it pushes the connecting bar (30) to fix it so that it does not shake due to the gap (y) between each component of the water lock clamp.

Specific details for implementing the invention

[0024] The present invention provides a multi-water lock clamp configured with a torsion spring that, when firefighters need to extend a fire hose during firefighting operations, pressurizes the outer side of the fire hose to restrict the movement of water or firefighting agent moving inside the fire hose, thereby enabling the connection between the nozzle and the fire hose to be performed quickly and conveniently, and allows the fire hose to be pressurized while remaining fixed without detaching outward from its position when the fire hose is pressurized.

[0026] Hereinafter, the preferred configuration and operation of the present invention for achieving the above objective in relation to the attached drawings will be described with reference to FIGS. 1 to 18 as follows.

[0028] First, before describing the present invention, the configuration thereof is examined with reference to FIGS. 1 to 3. The invention comprises a multi-water lock clamp configured with a torsion spring, wherein the first handle bar (10) is formed long in the longitudinal direction, and first and second hinge shafts (11, 13) are formed at the central and end portions, and a torsion spring (17) is formed to limit the sliding of a hose (h) located in the space (g) between the first and second hinge shafts (11, 13) when pressure is applied; and a second handle bar (20) positioned parallel to the first handle bar (10), wherein a third hinge shaft (21) is formed at the portion facing the second hinge shaft (11), and a locking groove (23) is formed on the other side where the third hinge shaft (21) is formed. It is configured with a connecting bar (30) formed between the first and second handle bars (10, 20), connected to a first hinge shaft (11) on one side and connected to a third hinge shaft (21) on the other side; and a locking member (40) having one side connected to the second hinge shaft (13) and a fourth hinge shaft (41) formed on the other side to be caught in the locking groove (23); so that when the second handle bar (20) is unfolded outward, a space (g) is formed between the first handle bar (10) and the connecting bar (30), and a fire hose (h) is positioned in the space, and when the second handle bar (20) is restored to its original state, the first handle bar (10) and the connecting bar (30) press the outside of the fire hose (h) to restrict the movement of water or fire extinguishing agent.

[0030] As shown in FIGS. 1 to 5, the first handle bar (10) is formed to be long in the longitudinal direction, and has first and second hinge shafts (11, 13) formed at the center and end portions. With respect to the first hinge shaft (11), one longitudinal portion is substantially the part that the user holds with their hand, and the other portion is the part that presses against the outside of the fire hose (h). More preferably, the upper portion is configured to press against the outside of the fire hose (h).

[0031] Here, the first handle bar (10) is configured with a torsion spring (17) that limits the hose (h) located in the space (g) between the first and second hinge shafts (11, 13) from being pushed when pressurized.

[0032] To explain the coupling structure of the torsion spring (17) in more detail, a torsion spring inlet groove (12) is formed on one side of the first handle bar (10), and a fixed shaft (14) is formed that is positioned in the torsion spring inlet groove (12) and extends to the inner side of the first handle bar (10). One side of the torsion spring (17) is fitted into the fixed shaft (14) so ​​that when the water lock clamp is in a folded state, the connecting bar (30) is pushed to fix it so that it does not shake due to the gap (y) between each component of the water lock clamp. When the water lock clamp is unfolded, it is pulled out upward so that the hose (h) located in the space (g) is fixed without being dislodged outward when pressurized.

[0033] In other words, the torsion spring (17) is hinge-connected to the first handle bar (10), the second handle bar (20), and the connecting bar (30), and according to the fluid structure, certain gaps are naturally formed between the facing surfaces. By pushing these parts together through the sliding properties of the torsion spring (17), the twisting of the first handle bar (10), the second handle bar (20), and the connecting bar (30) can be prevented.

[0034] In addition, when the torsion spring (17) is unfolded, as shown in FIGS. 16 and 17, when the hose (h) is pressed against the connecting bar (30), the hose (h) is not dislodged outwardly and is stably seated by the first handle bar (10) and the torsion spring (17) so that the hose (h) is joined to the connecting bar (30) and pressed without being pushed.

[0036] That is, the torsion spring (17) can perform the role of ensuring smooth pressurization without being pushed in one direction when pressurizing the hose (h), and also minimize shaking and twisting due to the gap between the first handle bar (10), the second handle bar (20), and the connecting bar (30), thereby increasing the fixing force.

[0038] As illustrated in FIG. 18, a protective cover (19) is configured between the second handle bar (20) and the connecting bar (30), with one side formed to surround the third hinge shaft (21) and coupled to the second handle bar (20), and the other side coupled to one side of the second handle bar (20) spaced apart from the third hinge shaft (21) at a certain distance, so as to minimize impact and damage caused by frequent collisions with the second handle bar (20) or the connecting bar (30) when the torsion spring (17) is pulled out.

[0039] The protective cover (19) has an end portion that comes into contact with the protective cover (19) when the torsion spring (17) is pulled out and pulled in, thereby preventing the torsion spring (17) from directly colliding with the second handle bar (20) or the connecting bar (30), and thus preventing damage to the second handle bar (20) or the connecting bar (30).

[0040] Generally, when frequent friction occurs in materials such as plastic and metal, the frictional part is damaged and a groove is formed. In the present invention, a protective cover (19) is configured to compensate for this problem so that it can be used for a long time and safety can be ensured.

[0041] In addition, the water lock multi clamp of the present invention must have good handling and be lightweight for convenience of use, so it must achieve maximum efficiency with minimal material. If the end of the torsion spring (17) is perforated due to continuous friction with the connecting bar (30), damage to the third hinge shaft (21) connecting the connecting bar (30) and the second handle bar (20) may occur, resulting in safety accidents of varying severity.

[0042] Here, the fire hose (h) is pressurized to restrict the movement of water, and if the connection between the second handle bar (20) and the connecting bar (30) is released while the fire hose (h) is being pressurized due to damage to the third hinge shaft (21), the fire hose (h) that is pressurized will expand again due to the pressure of the moving water, and due to that sudden expansion, other components of the clamp may be ejected and strike the worker's body, and considering the characteristics of the metal material, a fracture may occur, so the role of the protective cover (19) is very important.

[0044] As shown in FIGS. 1, 2, 3, 6, and 7, the second handle bar (20) is positioned parallel to the first handle bar (10), and a third hinge shaft (21) is formed in the part facing the second hinge shaft (11), and a catch groove (23) is formed on the other side where the third hinge shaft (21) is formed.

[0045] As the second handle bar (20) is positioned parallel to the first handle bar (10), the part extending backward relative to the center is the part that the user directly grips with their hand, and a locking groove (23) is formed on the other side.

[0047] As shown in FIGS. 6 and 7, on one side of the second handle bar (20), a groove (27) is formed that can be loosened or tightened while wrapping around the outside of the fire hydrant, and a hook (29) is formed at a certain distance from the groove (27) so that when the nozzle and the fire hose (h) are combined, the protrusion of the nozzle can be hooked to tighten and loosen.

[0048] The above-mentioned groove (27) is formed in a rectangular shape so as to be able to loosen or tighten the fire hydrant, and the reason the above-mentioned groove (27) is formed in a rectangular shape is that the fire hydrant is generally formed in a rectangular shape.

[0049] Meanwhile, although the above-mentioned groove (27) has been described and illustrated as a rectangular shape in the present invention, it may be formed as a polygon as needed and is not limited to the embodiments of the present invention.

[0051] In the case of the above-mentioned hook (29), when connecting the nozzle and the fire hose (h), the purpose is to prevent the fire hose (h) from detaching from the nozzle by tightening the nozzle strongly after connecting the fire hose (h).

[0052] As described above, since the groove (27) and the hook (29) are formed respectively, the worker (firefighter) can conveniently perform the work without carrying other tools for loosening and tightening the fire hydrant and the nozzle.

[0054] As shown in FIGS. 1, 2, 3, 8, and 9, the above connecting bar (30) is configured between the first and second handle bars (10, 20), connected to the first hinge shaft (11) on one side and connected to the third hinge shaft (21) on the other side, and is configured to pressurize by coming into contact with the upper part of the fire hose (h) located in the space (g).

[0055] At this time, as shown in FIG. 2, the fire hose (h) is positioned between the first handle bar (10) and the connecting bar (30) and is configured to have a clearance (y) so that the fire hose (h) is not short-circuited when pressurized.

[0056] In the case of the above clearance (y), since the fire hose (h) has some thickness when positioned in the space (g) and fully pressurized, it is desirable to form the clearance slightly smaller than that thickness.

[0058] As shown in FIGS. 1, 2, 3, and 10, the above fixing member (40) has one side connected to the second hinge shaft (13) and the other side formed with a fourth hinge shaft (41) that is caught in the catch groove (23). When the fourth hinge shaft (41) is caught in the catch groove (23) after the fire hose (h) is finally positioned in the space (g), the fire hose (h) is positioned in the space (g) and the outer side of the fire hose (h) is completely wrapped around, and the outer side can be pressurized, so even if it is pushed to one side, it will only move slightly within the space (g) and can be fundamentally prevented from being ejected from the space (g).

[0060] Here, an expansion groove (43) is formed on the inner side of the above-mentioned catch member (40) so that the space (g) can be expanded to minimize collision with the fire hose (h) when the fire hose (h) is positioned in the space (g), thereby preventing damage to the fire hose (h) and ensuring stability of the pressurization.

[0061] In addition, the connecting portion where the expansion groove (43) of the above-mentioned locking member (40) is formed is rounded so that there are no sharp parts at all, thereby further improving its stability.

[0063] Meanwhile, the fourth hinge shaft (41) of the above-mentioned locking member (40) is configured to rotate in place to minimize friction when sequentially engaging the outer part of the second handle bar (20) and the inner side of the locking groove (23).

[0064] That is, when the fire hose (h) is positioned in the space (g) and pressurized, a force stronger than that pressure must be applied, so that when the hooking groove (21) is hooked onto the fourth hinge shaft (41), it is naturally induced to be hooked without requiring a lot of force due to the pressure, thereby making it easy to hook and promoting convenience for the worker.

[0065] In addition, the outer side of the second handle bar (20) and the portion extending from the locking groove (21) are formed in a rounded shape so that the fourth hinge shaft (41) moves like a roller.

[0067] As shown in FIG. 12, on the other side of the first and second handle bars (10, 20) on which the locking member (40) is configured, so that the first and second handle bars (10, 20) can be fixed without spreading apart while the fire hose (h) is pressurized, " A fixing means (50) in the shape of a ruler is configured.

[0068] That is, the above fixing means (50) is configured to completely fix the other end of the first and second handle bars (10, 20) that pressurize the fire hose (h) without spreading apart, so that the clamp does not come loose due to external factors such as pressure, thereby further increasing stability.

[0070] At this time, as shown in FIG. 12, a locking projection (15, 25) is formed on the outer side of each of the first and second handle bars (10, 20), and both sides of the fixing means (50) can be fixed by being caught on the locking projections (15, 25) respectively.

[0071] Additionally, although not illustrated, one side of the fixing means (50) may be configured to be hinge-connected to the first handle bar (10) or the second handle bar (20) so as to be rotatable, and the other side may be configured to be fixed to the catch of the first handle bar (10) or the second handle bar (20).

[0073] Meanwhile, as shown in FIG. 11, a guide groove (33) is formed in the longitudinal direction on the upper part of the connecting bar (30), and a protruding guide (26) corresponding to the guide groove (33) is formed on the lower part of the second handle bar (20). When the fire hose (h) is positioned in the space (g) and pressurized, the protruding guide (26) is fitted into the guide groove (33) to prevent twisting of the clamp, thereby ensuring stability against the pressure of water moving inside the fire hose (h).

[0075] According to the multi-water lock clamp configured with a torsion spring of the present invention, while maintaining the original purpose of the multi-water lock clamp, stable operation is possible by fundamentally preventing the fire hose from detaching through a structure that completely wraps around the outer side of the fire hose and a double fixing structure that prevents the clamp from loosening. Furthermore, it is a useful invention that prevents damage to the fire hose by securing more space for the fire hose to be positioned, and enables quick and accurate locking by minimizing friction between the locking groove and the shaft fitted into the locking groove when the fire hose is positioned after the clamp is unfolded and restored to its original state.
