Description

Technical Field

[0001] This utility model relates to the field of anti-theft technology, specifically to a lock bar and an anti-theft lock. Background Technology

[0002] Anti-theft locks are a type of lock that enhances security through different lock cylinder principles. The main types include pin tumbler locks, wafer locks, magnetic locks, IC card locks, and fingerprint locks. U-locks (common U-locks are either pin tumbler locks or wafer locks) are typically used to lock movable vehicles such as bicycles and electric scooters.

[0003] A U-shaped lock consists of a U-shaped locking rod and a long, narrow lock body. The outer wall of the lock body has lock holes that fit the two ends of the locking rod. By creating limiting notches on the outer walls at both ends of the locking rod, once both ends of the locking rod are inserted into the two lock holes simultaneously, the limiting blocks of the lock cylinder inside the lock body jam the notches, preventing the locking rod from being removed from the lock body, thus achieving the purpose of locking and restricting the movement of the vehicle.

[0004] During use, there are instances where thieves use force to damage the lock bar (such as cutting it with a cutting machine or hydraulic shears) to eliminate the U-lock's restrictive function and move the vehicle to commit theft. While some locks with positioning functions are available in the current technology, these locks typically rely on their internal positioning modules (such as GPS or BeiDou positioning modules) to transmit location information wirelessly for positioning.

[0005] However, when used indoors or in areas with signal obstruction (such as underground parking garages), it is easy to cause positioning failure, or after the positioning module is forcibly removed and discarded, it is difficult to track the thief's driving trajectory and recover the stolen vehicle. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a locking bar and an anti-theft lock to solve the problem that it is difficult to track the thief's driving trajectory and recover the stolen vehicle after the existing locks are forcibly dismantled and discarded.

[0007] This utility model is achieved through the following technical solution:

[0008] A locking bar includes a hollow bar with an open end, wherein a cover for covering and sealing the opening of the bar is detachably fixed to the open end of the bar, and a warning medium is stored inside the bar.

[0009] Furthermore, a valve is provided on the outside of the closed end of the rod, and the output end of the valve is fixedly connected to the end face of the rod, and the output end of the valve is connected to the inside of the rod.

[0010] Furthermore, an air guide tube is provided inside the rod body. One end of the air guide tube is connected to the output end of the valve nozzle, and the other end extends along the length of the rod body and is connected to the inside of the rod body.

[0011] A flow channel for warning of medium flow is provided between the outer wall of the air guide tube and the inner wall of the rod.

[0012] Furthermore, one end of the air guide tube has a hollow structure and the open end of the air guide tube is connected to the valve nozzle, and a connection hole is provided on the side wall of the closed end of the air guide tube.

[0013] Furthermore, a storage cavity for placing the air guide tube is provided in the middle of the rod body, and the inner diameters at both ends of the rod body are smaller than the radial dimension of the storage cavity along the rod body.

[0014] One end of the receiving cavity is connected to the valve stem output end, and the other end is connected to the rod body opening end;

[0015] The air guide tube is embedded in the receiving cavity, with one end of the air guide tube abutting against the end wall of the receiving cavity facing the valve, and the other end abutting against the other end wall of the receiving cavity.

[0016] Furthermore, both ends of the air guide tube are coaxially fixedly connected with annular protrusions, and the outer circular surface of the annular protrusions is in contact with the inner wall of the receiving cavity.

[0017] The annular protrusion at the closed end of the air duct has a through hole extending axially toward the air duct.

[0018] Furthermore, a protrusion is provided on the outer wall of the air guide tube. One end of the protrusion is fixedly connected to the outer wall of the air guide tube, and the other end extends radially toward the air guide tube and abuts against the inner wall of the rod.

[0019] Furthermore, multiple sets of protrusions are provided on the outer wall of the air guide tube, and the multiple sets of protrusions are evenly arranged along the length direction of the air guide tube.

[0020] Furthermore, each group of protrusions contains multiple protrusions, which are evenly arranged around the circumference of the air guide tube, and a flow channel for warning the flow of medium is provided between two adjacent protrusions.

[0021] An anti-theft lock includes the aforementioned lock rod and lock body. The lock body has a lock cylinder inside. The outer wall of the lock body has two lock holes that correspond one-to-one with the two ends of the lock rod. When the two ends of the lock rod are inserted into the two lock holes and locked by the lock cylinder, the cover and valve are completely embedded in the corresponding lock holes.

[0022] The beneficial effects of this utility model are as follows:

[0023] This lock bar and anti-theft lock feature a hollow structure. The internal space stores a warning medium. When the bar is violently broken, cut, or sheared, the inner and outer sides connect, causing the warning medium to leak out and adhere to the vehicle's surface or the thief's body. This provides a conspicuous marker for tracking the thief or vehicle's movement, facilitating the recovery of the stolen vehicle. Furthermore, the cap is detachably connected to the open end of the bar, allowing the cap to be removed and the amount or material of the warning medium added freely, reducing the impact of medium deterioration on its effectiveness.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] In the above description of this utility model, it should be noted that the terms "one side," "the other side," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0039] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0040] Please see Figure 1-9 This utility model provides a technical solution: a locking rod, including a rod body 1 with a hollow structure and an open end, a cover 2 for covering and sealing the opening of the rod body 1 is detachably fixed to the open end of the rod body 1, and a warning medium 3 is stored inside the rod body 1.

[0041] In this solution, the pole 1 is designed as a hollow structure, and the internal space is used to store the warning medium 3. When the pole 1 is violently broken, cut, or sheared, the inner and outer sides of the pole 1 are connected, and the warning medium 3 leaks out and adheres to the surface of the vehicle (such as the frame, tires, etc.) or the body of the thief (such as limbs, clothing, etc.), providing a conspicuous marker for subsequent tracking of the movement trajectory of the thief or the vehicle (such as retrieving surveillance footage to quickly locate the thief or the vehicle), so as to facilitate the recovery of the stolen vehicle.

[0042] Meanwhile, the cap 2 is detachably fixed to the open end of the rod 1, allowing the cap 2 to be removed and the quantity or material of the warning medium 3 to be freely added, reducing the impact of deterioration of the warning medium 3 on the warning effect.

[0043] The rod 1 can be made of a hard material (such as metal steel) or a soft material (such as high-strength nylon), with a preference for a hard material.

[0044] Warning medium 3 is preferably a liquid medium, and the liquid medium includes, but is not limited to, the following four types:

[0045] 1. Fluorescent dye solution (Rhodamine B): strong fluorescence and color development; can still be tracked by ultraviolet light at night or in the dark; strong adhesion; difficult to wash; easily stains clothes / skin.

[0046] 2. Oil-based pigments (red ink), high viscosity, not easily volatile, and can adhere to the surface of objects for a long time;

[0047] 3. Invisible ink (UV reactive type): normally colorless, requires ultraviolet light detection, and has strong concealment.

[0048] 4. Odorous liquids (such as thiol compounds) can release strong, pungent odors, making them easy for police dogs to track or for people to identify.

[0049] Additionally, the outer circumference of the open end of the rod 1 is provided with external threads, and the cap 2 has a hollow structure with one open end, and the inner circumference of the open end is provided with internal threads that match the external threads on the rod 1. The open end of the rod 1 is inserted into the open end of the cap 2 and fixedly connected by the threaded engagement, thereby achieving the purpose of covering and sealing the opening of the rod 1 and preventing the warning medium 3 inside the rod 1 from moving out.

[0050] Meanwhile, a sealing gasket (such as a rubber gasket or silicone gasket) can be placed inside the closed end of the cap 2. When the cap 2 is tightened, the sealing gasket is squeezed and deformed by the end face of the open end of the rod body 1 and the end face of the closed end of the cap 2, which improves the sealing performance and further limits the loss of the warning medium 3 (such as evaporation) or the entry of moisture in the outside air into the inside of the rod body 1, causing the warning medium 3 to deteriorate.

[0051] Warning medium 3 can also be selected as a solid powder medium, which includes, but is not limited to, the following two types:

[0052] 1. Fluorescent powder (zinc sulfide) is lightweight and easily dispersed, adhering to clothing or skin, and developing color under ultraviolet light.

[0053] 2. The dyeing powder (methylene blue powder) turns color when it comes into contact with water, and requires multiple washes to remove it from the skin after it gets on it.

[0054] When the solid medium is loaded into the rod 1, during the process of the thief using a cutting machine or other tools to cut and destroy it, the high-speed rotation of the cutting blade of the cutting machine can roll up the solid medium and throw it into the air, causing the solid medium to move a long distance so that it can adhere to the thief's body or the surface of the vehicle.

[0055] Users can freely select and fill the aforementioned warning medium 3 into the rod body 1 to achieve different warning effects. For example, oily pigments and odorous liquids can be mixed and used to provide warnings simultaneously through visual and olfactory means.

[0056] In this embodiment: a valve 4 is provided outside the closed end of the rod 1, the output end of the valve 4 is fixedly connected to the end face of the rod 1, and the output end of the valve 4 is connected to the inside of the rod 1.

[0057] In this design, with the cap 2 sealing the opening of the sealing rod 1, a sealed chamber for storing the warning medium 3 is formed inside the rod 1. The valve 4 is normally closed and is used to connect to an external inflation device (such as an air pump / pump), making the valve 4 the only channel for air to flow into the rod 1. The external inflation device forces air into the rod 1, increasing the internal pressure and creating a high-pressure state. When the rod 1 is violently damaged, the pressure will force the warning medium 3 out and spray it, allowing it to travel a longer distance and cover a larger area compared to natural flow or discharge.

[0058] However, the pressure inside rod 1 needs to be controlled to avoid excessive or insufficient pressure. This can be adjusted by observing the pressure gauge on the air pump. For example, the safe pressure range is 0.3-0.6 MPa (hard metal rod 1) and 0.1-0.3 MPa (soft composite rod 1).

[0059] Among them, valve 4 is a mature existing technology, widely used in bicycle tires, car tires, etc., mainly used to inflate and deflate the tire to adjust the pressure. It is kept in a normally closed state, which can keep the internal pressure of the tire stable. The operating principle of valve 4 in this device is similar to that of valve 4 on a tire. There is no improvement or separate design in its structure and principle, so it will not be described in detail here.

[0060] In this embodiment: an air guide tube 5 is provided inside the rod body 1. One end of the air guide tube 5 is connected to the output end of the valve 4, and the other end extends along the length of the rod body 1 and is connected to the inside of the rod body 1.

[0061] A flow channel for warning medium 3 is provided between the outer wall of the air guide pipe 5 and the inner wall of the rod 1.

[0062] In this design, the air duct 5 is used to transport and store air, and the flow channel formed between the outer wall of the air duct 5 and the inner wall of the rod 1 is used to store the warning medium 3. High-pressure air is stored inside the air duct 5. When the rod 1 is violently damaged, the flow channel connects to the outside of the rod 1. Driven by the high-pressure air inside the air duct 5, the warning medium 3 in the flow channel is continuously forced out or blown out, reducing the probability that the warning medium 3 would be difficult to force out or blow out if the damaged area is an air storage area and the high-pressure air leaks out directly.

[0063] Meanwhile, the air duct 5 can be made of metal, so that even if the rod 1 is damaged and broken, the air duct 5 can still play a supporting and locking role.

[0064] In this embodiment: one end of the air guide tube 5 is hollow and the open end of the air guide tube 5 is connected to the valve 4. A connection hole 51 is provided on the side wall of the closed end of the air guide tube 5.

[0065] In this design, a piston can be installed inside the air duct 5. The piston slides and seals against the air duct 5 along its length. The piston isolates the air and the warning medium 3 (liquid medium) within the air duct 5. The pressure difference drives the piston to slide, thereby forcing the warning medium 3 out of the air duct 5 and further out through the damaged section of the rod 1. The piston's shape can be designed according to the internal shape of the air duct 5. For example, a spherical shape allows the piston to slide within the curved section of the air duct 5, providing a large stroke. A cylindrical shape provides better sealing, but it can only slide within a straight section near the opening of the rod 1.

[0066] The size of the connection hole 51 allows the liquid medium to flow in or out freely. For example, when the height of the liquid medium outside the air guide pipe 5 does not exceed the position of the connection hole 51, the liquid medium can flow into the air guide pipe 5 through the connection hole 51 and at the same time force the air in the air guide pipe 5 out.

[0067] When adding liquid medium (warning medium 3) into rod 1, the steps are as follows:

[0068] Step 1: Add the liquid medium into the syringe, remove the cap 2, place the open end of the rod 1 vertically upward, and insert the syringe needle into the flow channel between the outer wall of the air tube 5 and the inner wall of the rod 1 through the opening of the rod 1.

[0069] Step 2: Push the syringe plunger to inject liquid medium to fill the flow channel. When the liquid level is higher than the height of the connection hole 51, the liquid medium will automatically flow into the air guide tube 5 to fill the internal space of the air guide tube 5 (the space where the piston faces away from the opening of the rod body 1). When the liquid level completely covers the connection hole 51, tighten the cap 2. The section of the piston facing the opening of the rod body 1 will retain a space for storing air.

[0070] Step 3: Connect valve 4 to external inflation equipment, and inflate air into air guide tube 5. The piston slides away from the opening end of rod 1 under the push of air, squeezing out the liquid medium in air guide tube 5, filling or nearly filling the external space of air guide tube 5. Continue to inject air to gradually form a high pressure state until the target pressure value is reached, then stop inflation and end the injection.

[0071] In this embodiment: a receiving cavity 11 for placing the air guide tube 5 is provided in the middle of the rod body 1, and the inner diameters at both ends of the rod body 1 are smaller than the radial dimension of the receiving cavity 11 along the rod body 1.

[0072] One end of the receiving cavity 11 is connected to the output end of the valve 4, and the other end is connected to the open end of the rod 1.

[0073] The air guide tube 5 is embedded in the receiving cavity 11. One end of the air guide tube 5 is attached to the end wall of the receiving cavity 11 facing the valve 4, and the other end is against the other end wall of the receiving cavity 11.

[0074] In this design, the rod 1 is composed of two symmetrical metal strips spliced ​​together to facilitate the production and processing of the internal structure of the rod 1. After the air duct 5 is installed, it is fixedly connected by welding or other methods.

[0075] A sealing gasket (rubber gasket, silicone gasket, etc.) can be installed on the opening end of the air guide tube 5. By using the abutment and compression of the two end walls of the receiving cavity 11, a seal is formed between the end face (sealing gasket) of the opening end of the air guide tube 5 and the end face of the receiving cavity 11, thus restricting the air injected from the valve 4 from overflowing out of the air guide tube 5.

[0076] In this embodiment: both ends of the air guide tube 5 are coaxially fixedly connected with annular protrusions 52, and the outer circular surface of the annular protrusions 52 is in contact with the inner wall of the receiving cavity 11.

[0077] The annular protrusion 52 at the closed end of the air guide tube 5 is provided with a through hole 53 extending axially toward the air guide tube 5.

[0078] In this design, the annular protrusion 52 supports both ends of the air delivery tube 5, making the connection between the air delivery tube 5 and the rod body 1 more stable. The closed end of the air delivery tube 5 covers and blocks the input channel at the open end of the rod body 1, allowing the exchange of warning medium 3 (liquid medium) or air only through the through hole 53. The through hole 53 is used to guide the needle insertion of the syringe to facilitate the addition of warning medium 3.

[0079] Multiple through holes 53 are provided. When the needle is inserted into one of the through holes 53, the air inside the rod body 1 can be discharged from the other through holes 53, which further facilitates the operation of adding the warning medium 3.

[0080] In this embodiment: a protrusion 54 is provided on the outer wall of the air guide tube 5. One end of the protrusion 54 is fixedly connected to the outer wall of the air guide tube 5, and the other end extends radially toward the air guide tube 5 and abuts against the inner wall of the rod body 1.

[0081] In this design, the protrusion 54 serves as a support structure between the outer wall of the air guide tube 5 and the inner wall of the rod body 1, which can improve the stability of the connection between the two and make the overall structure of the locking rod more compact and stronger.

[0082] In this embodiment, multiple sets of protrusions 54 are provided on the outer wall of the air guide tube 5, and the multiple sets of protrusions 54 are evenly arranged along the length direction of the air guide tube 5.

[0083] In this scheme, multiple sets of protrusions 54 are used to form multiple points of support along the length of the air pipe 5, so that the air pipe 5 and the rod 1 interact and support each other, thereby improving the rod 1's resistance to compression (shear).

[0084] In this embodiment: each group of protrusions 54 contains a plurality of protrusions 54, the plurality of protrusions 54 are evenly arranged around the circumference of the air guide tube 5, and a flow channel for the warning medium 3 to flow through is provided between two adjacent protrusions 54.

[0085] In this design, multiple protrusions 54 arranged around the circumference of the air guide tube 5 are grouped together. This not only improves the stability of the connection between the air guide tube 5 and the rod 1, but also plays a centering role for the air guide tube 5, so as to facilitate the installation of the air guide tube 5.

[0086] An anti-theft lock includes the aforementioned lock rod and lock body 6. The lock body 6 has a lock cylinder inside. The outer wall of the lock body 6 has two lock holes 61 that correspond one-to-one with the two ends of the rod 1. When the two ends of the rod 1 are respectively inserted into the two lock holes 61 and locked and fixed by the lock cylinder, the cover 2 and the valve 4 are completely embedded in the corresponding lock holes 61.

[0087] In this solution, by increasing the thickness of the outer wall of the lock body 6 or increasing the depth of the lock hole 61, the two ends of the rod body 1 are inserted into the two lock holes 61 respectively and locked by the lock cylinder. The cover 2 and the valve 4 are completely embedded in the corresponding lock hole 61, which avoids the cover 2 and the valve 4 being exposed outside the lock body 6 and being damaged by violence, which would make it difficult for the warning medium 3 to be pressed out and diffused, thus affecting the warning effect.

[0088] Among them, the specific model of lock body 6 can be selected as Zhejiang Zhongli U-shaped lock 82908.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
