Description

Technical Field

[0001] The invention relates to the technical field of automobile auxiliary tools, in particular to a tire detection and cleaning tool. Background Art

[0002] When a car is driving, foreign objects such as stones, glass, and iron filings are easily crushed into the tread seams of the car tires or into the rubber layer of the tire crown. In particular, since the tire tread is elastic, it is difficult for foreign objects to fall off by themselves after being stuck in the tire tread. These foreign objects will increase tire wear, produce tire noise, and even affect the car's braking ability. In severe cases, they may even cause a tire blowout.

[0003] Existing "tire cleaning tools" generally include: simple curved hooks; multi-tooth tire stone cleaning hooks, welded teeth type; multi-tooth tire tooth picks; and combined tools with replaceable hook teeth.

[0004] The above special tools can easily remove foreign objects such as stones embedded in the tire pattern, but the hook teeth of these special tools, including replaceable hook teeth, are relatively fixed in the direction of the hook teeth and the position of the handle when used, which is only suitable for cleaning foreign objects such as stones embedded in the tire pattern, and it is not easy to remove tiny hard foreign objects that are embedded in the rubber surface of the tire crown, such as sharp stones, metal chips, glass slag, etc. In particular, when the passenger car tire is in the state of a complete vehicle, the crown surface is not easy to observe, and some tiny sharp hard foreign objects are embedded in the rubber surface of the crown, resulting in very small notches. Under natural light conditions, the inner part of the tire is darker, and these small notches are also difficult to be found; under insufficient light conditions, it is even more difficult to observe. When the car is driving on an uneven road, the local impact force will cause the sharp foreign objects to pierce deeper and deeper, which is very harmful to the tire. Therefore, there is an urgent need for a foreign body cleaning tool for automobile tires that can solve the above defects. Summary of the invention

[0005] The specific technical solution of the present invention is to provide a tire detection and cleaning tool to solve the problem that foreign matter in existing automobile tires is difficult to clean.

[0034] Figure 1 FIG. 1 is a schematic diagram of the structure of a tire inspection and cleaning tool according to an embodiment of the present invention. Figure 1 As shown, the tire detection and cleaning tool of the embodiment of the present invention comprises: a sheath 1, a knob 2 and a universal tooth 3; the universal tooth 3 comprises a universal tooth body and a curved hook section 16, and the curved hook section 16 is extended at the bottom of the universal tooth body; the knob 2 and the sheath 1 are threadedly sleeved on the universal tooth body in sequence along the axial direction of the universal tooth body; as shown Figure 2 As shown, a first light source is mounted on the sheath 1 and faces the hook section 16 .

[0035] It should be noted that the light-emitting element of the first light source may be an LED light source, or other small light sources such as a miniature bulb, which is not specifically limited here.

[0036] It should be noted that the inner hole of the sheath 1 has an internal thread, the inner hole of the knob 2 has an internal thread, and the outer diameter of the universal tooth body has an external thread; the universal tooth body and the sheath 1, the universal tooth body and the knob 2 form a thread pair through threaded cooperation, which can be locked with each other. Among them, the universal tooth can rotate the angle and adjust the extension length through threaded cooperation in the sheath 1, and can be locked and fixed by the knob 2.

[0037] like Figure 4 , Figure 5 as well as Figure 6 As shown, the hook section 16 is formed by taking the bottom of the universal tooth body as the starting end and extending in the direction away from the bottom of the universal tooth body. In order to enhance the structural strength, the hook section 16 and the bottom of the universal tooth body can be an integrated structure.

[0038] It can be understood that, in order to facilitate the cleaning of foreign objects, the convex side of the curved hook section 16 is in a convex arc shape 17 , and the concave side of the curved hook section 16 is provided with a tiny notch 18 .

[0039] In the embodiment of the present invention, the universal tooth body and the sheath 1 move relative to each other to adjust the rotation angle and extension length of the hook section 16, and finally the sheath 1, the knob 2 and the universal tooth body remain relatively still by tightening the knob 2. The tire detection and cleaning tool provided by the embodiment of the present invention has a self-illumination function, and the direction and extension length of the hook section are adjustable. It can not only conveniently detect and clean foreign objects that are stuck in the rubber surface of the tire crown, but also clean foreign objects such as stones embedded in the tire pattern; it is not affected by the brightness of the environment, and can conveniently use the self-contained lighting device to observe the surface condition of the tire crown and accurately find small wounds on the crown.

[0040] Based on the above embodiments, Figure 7 As shown, the hook section 16 is matched with the sheath 1 so that the hook section 16 is received inside the sheath 1 .

[0041] It should be noted that, through the relative movement between the universal tooth body and the sheath 1, the hook section 16 moves toward the sheath 1, the hook section 16 is located inside the sheath 1, and the hook section 16 is fixed inside the sheath 1 by the locking knob 2 to prevent the hook section 16 from scratching objects. The size of the hook section 16 needs to be compatible with the inner diameter of the sheath 1.

[0042] Based on the above embodiments, Figure 4 , Figure 5 as well as Figure 6 As shown, a limit mark 19 is provided at the junction of the universal tooth body and the curved hook section 16 .

[0043] It should be noted that the limit mark 19 can be a fluorescent coating or a scale mark. The limit mark 19 is provided to indicate that the depth of the foreign body is close to the inner wall of the tire.

[0044] On the basis of the above embodiment, a fixing ring 6 is sleeved on the outer wall of the sheath 1 , and the first light source is located on the fixing ring 6 .

[0045] It should be noted that the fixing ring 6 in an annular structure and the sheath 1 may be in an integrated structure.

[0046] It can be understood that the first light source can be installed inside the fixing ring 6, and a transparent lampshade 5 is installed outside the first light source, and the transparent lampshade 5 and the fixing ring 6 are sealed to prevent dust and water stains from entering the inside of the fixing ring 6. The central axis of the first light source and the central axis of the sheath 1 can be arranged in parallel.

[0047] On the basis of the above embodiment, the first light source is in an annular structure and is coaxially arranged with the sheath 1 .

[0048] It should be noted that, in order to improve the lighting effect, the first light source may be in a ring structure, and the light of the first light source directly surrounds the curved hook section 16 for illumination.

[0049] On the basis of the above embodiment, the tire detection and cleaning tool further comprises a connecting rod 4 connected to the sheath 1 , and a second light source facing the hook section 16 is mounted on the connecting rod 4 .

[0050] It should be noted that the left end of the connecting rod 4 is connected to the outer wall of the sheath 1, the second light source is located inside the connecting rod 4, and a transparent lampshade 5 is installed outside the second light source. The transparent lampshade 5 and the connecting rod 4 are sealed to prevent dust and water stains from entering the interior of the connecting rod 4.

[0051] Based on the above embodiments, Figure 2 As shown, a light shield 13 for shielding light away from the hook section 16 is installed at the second light source.

[0052] It should be noted that a through groove is provided on the connecting rod 4, the transparent lampshade 5 is located in the through groove, and a light shield 13 is installed near the transparent lampshade 5. The light shield 13 located in the through groove can prevent the light emitted by the second light source from causing glare, thereby affecting the user's observation of the curved hook section 16 and the actual working conditions.

[0053] It is understandable that the shading cover 13 and the connecting rod 4 can be an integrated structure, and the shading cover 13 and the transparent lampshade 5 are sealed and installed.

[0054] On the basis of the above embodiment, the angle between the central axis of the second light source and the central axis of the connecting rod 4 is 20° to 80°.

[0055] It should be noted that when the second light source is powered on and emits light, due to the provision of the light shield 13, the curved hook section 16 is within the coverage of the illuminated area 15 of the second light source, and the light emitted by the second light source will not dazzle the user.

[0056] Based on the above embodiments, Figure 3 As shown, the tire detection and cleaning tool further comprises a handle 7 sleeved on the outer wall of the connecting rod 4 , and a third light source facing the hook section 16 is mounted on the handle 7 .

[0057] It should be noted that the handle 7 is sleeved on the right end of the connecting rod 4. The third light source is located inside the handle 7, and a transparent lampshade 5 is installed outside the third light source. The transparent lampshade 5 and the handle 7 are sealed to prevent dust and water from entering the handle 7.

[0058] It can be understood that the connecting rod 4 and the handle 7 are both hollow structures, the third light source is installed at the head end of the handle 7, the power supply 12 is installed inside the handle 7, and the tail end of the handle 7 is equipped with a power supply compartment cover 8; the power supply compartment cover 8 is equipped with a power switch 9 and a switch retainer 10, and the switch retainer 10 is arranged around the power switch 9. The power supply 12 in the handle 7 is connected to the power switch 9 on the power supply compartment cover 8. Among them, the handle 7 is connected to the connecting rod 4 to facilitate the layout of the wire 11. The head end of the handle 7 is the end close to the sheath 1, and the tail end of the handle 7 is the end away from the sheath 1.

[0059] In the embodiment of the present invention, the light source 14 includes one or more of the first light source, the second light source and the third light source, that is, the first light source, the second light source and the third light source can be arranged separately or two or three can be arranged at the same time. The following is an example in which the light source 14 includes the first light source, the second light source and the third light source at the same time, and the corresponding wire 11 includes the first wire, the second wire and the third wire.

[0060] A first light source and a first wire connected to the first light source are installed inside the fixing ring 6, a second light source and a second wire connected to the second light source are installed inside the connecting rod 4, a third light source and a third wire connected to the third light source are installed inside the handle 7, and the first wire, the second wire and the third wire are connected in parallel to the power switch 9.

[0061] It is understandable that the first light source, the second light source and the third light source may be powered and controlled independently, which is not specifically limited here.

[0062] The working process of the tire detection and cleaning tool is described in detail below.

[0063] like Figure 2 , Figure 8 , Fig. 9 as well as Fig.10As shown, after pressing the switch 9, the power supply 12 is turned on, and the light source 14 is powered on to emit light, which can illuminate the area 15 around the hook section 16. Move the handle 7, and use the light emitted by the light source 14 to observe whether there are punctures or foreign objects embedded on the surface of the tire crown; according to the direction of the notch in the tire crown punctured by the foreign object, adjust the direction of the hook section 16 to the corresponding direction, and appropriately adjust the extension length of the hook section 16. After the adjustment of the hook section 16, lock it with the knob 2; hold the handle 7 with one hand, and push the front end of the connecting rod 4 or the knob 2 with the other hand, so that the hook section 16 is inserted into the notch 21 in the rubber layer 22 of the tire crown punctured by the foreign object 20 ; After the hook section 16 is inserted into the notch 21 on the surface of the tire crown pierced by the foreign object, when the hook section 16 contacts the foreign object 20, a slight touch (slight vibration) will be felt on the hand, indicating that there is a hard foreign object in the notch 21; if no slight touch is felt, it indicates that there is no hard foreign object in the notch 21; the hook section 16 is gently shaken (front and back, left and right) along the edge of the foreign object 20, inserted into the side of the foreign object 20, and pried upward and sideways, and the foreign object 20 is expelled outward with the help of the elasticity of the tire rubber;

[0064] For foreign objects such as stones embedded in the crown groove, the hook section 16 can be adjusted to the corresponding direction according to the general direction of the crown groove of the tire, and locked with the knob 2, and the hook section 16 is inserted into one side of the foreign object and pried upward to remove the embedded foreign object;

[0065] The hook section 16 has a limit mark 19, which is a warning mark. When the depth of the foreign object 20 embedded in the tire crown rubber layer 22 reaches the limit mark 19, it indicates that the foreign object 20 has approached the inner wall of the tire, and the tire may leak. It is necessary to have a professional tire maintenance shop check, repair or replace the tire with a new one;

[0066] After the tire inspection and cleaning tool is used, the power supply 12 is turned off, the hook section 16 can be stored in the sheath 1, and the hook section 16 is fixed in the sheath 1 by the knob 2 to prevent the hook section 16 from scratching objects.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
