Description

Technical Field

[0001] The utility model relates to the technical field of automobile lamp adjustment tools, and more specifically, to an adjustment tool for the optical axis of a vehicle headlight. Background Art

[0002] The light axis of a car headlight refers to the direction of the light beam projected by the vehicle's headlights, which is divided into horizontal and vertical axes. The correct setting of the light axis of the headlight is very important because it affects the lighting effect of the vehicle on the road when driving at night, as well as the illumination of other vehicles and pedestrians.

[0003] According to the current staff input and work efficiency requirements of the inspection line, the adjustment of the vehicle headlight axis is generally performed by one person on two cars of different models at the same time, and the headlight axis of the two cars is adjusted to the qualified range within a limited working time.

[0004] Since the optical axis adjustment screw structures of different car models are usually different, operators need to frequently switch at least two different screwdrivers to adjust different optical axis adjustment screws according to different car models. In addition, the existing screwdrivers are generally straight-line in shape, and the linear screwdrivers need to keep their axes on the same straight line when in use, which limits the operating angle of the screwdriver. When using the linear screwdriver, operators need to frequently disengage the screwdriver head from the adjustment screw to adjust the grip angle of the screwdriver, and cannot continuously screw and adjust the adjustment screw. More hand movements are required to complete the same screwing task, which increases the complexity of the operation and consumes more physical effort. The above two situations will result in longer working hours and reduce the adjustment efficiency of the optical axis of the car headlights. Utility Model Content

[0005] In view of the problem that in the above-mentioned prior art, when adjusting the light axis of the headlights of cars of different models, it is necessary to frequently switch different screwdrivers, and the screwdrivers cannot continuously tighten the screws, resulting in low efficiency in adjusting the light axis of the headlights of the cars, the utility model provides a tool for adjusting the light axis of the headlights of cars, which can be used for adjusting the light axis of the headlights of two models of cars at the same time, reducing the switching frequency of the tools, and can continuously tighten the screws, shortening the working hours.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is:

[0007] A tool for adjusting the light axis of a car headlight comprises a first cylinder, one end of which is provided with a first cutting head; a connecting piece and a second cylinder, the other end of the first cylinder being connected to the connecting piece; one end of the second cylinder is provided with a second cutting head having a structure different from that of the first cutting head, the other end of the second cylinder being connected to the connecting piece, and the axes of the first cylinder and the second cylinder are parallel to each other.

[0008] In the above technical scheme, when adjusting the light axis of the headlight of one type of car, after the first cutter head is connected with the adjusting screw of the light axis of the car headlight, the operator can hold the first cylinder with one hand to keep the axis of the first cylinder in the same straight line, and hold the second cylinder with the other hand, and shake the second cylinder with the first cylinder as the rotation axis, so that the entire tool rotates around the axis of the first cylinder, thereby screwing and adjusting the adjusting screw of the light axis of the car headlight. When it is necessary to adjust the light axis of the headlight of another type of car, the second cutter head is replaced and the adjusting screw of the car of the same type is screwed in the same way. The tool has two cutter heads, so that the tool can adjust the light axis of the headlight of two different types of cars, which can reduce the switching frequency of the tool. Moreover, the tool does not need to leave the first / second cutter head from the position of the adjusting screw during use. The function of continuous rotation of the tool can be achieved by continuously shaking the first cylinder or the second cylinder. Its rotation and operation are more convenient and flexible, which can reduce the hand movements of the staff, reduce the fatigue of the wrist and arm, and is conducive to improving the adjustment efficiency of the light axis of the car headlight.

[0009] Preferably, the connecting member comprises a first straight rod portion, an oblique rod portion and a second straight rod portion, the axis of the first straight rod portion and the axis of the second straight rod portion are parallel to each other, one end of the first straight rod portion and one end of the second straight rod portion are respectively connected to two ends of the oblique rod portion; the first column is coaxially connected to the first straight rod portion, and the second column is coaxially connected to the second straight rod portion. Such a connecting member has a simple structure, is light in weight, and is easy to process.

[0010] Wherein, the axis of the oblique rod portion and the axis of the first straight rod portion may form an acute angle, a right angle or an obtuse angle. Preferably, the axis of the oblique rod portion and the axis of the first straight rod portion form an obtuse angle, and the distance between the end of the first column and the end of the second column is greater than the sum of the lengths of the first column and the second column. It is understandable that when the axis of the oblique rod portion and the axis of the first straight rod portion form an obtuse angle, the axis of the second straight rod portion also forms an obtuse angle with the axis of the oblique rod portion. In this way, the first column and the second column can maintain a certain distance in the axial direction of one of them, so that the two hands of the staff can maintain a certain distance when using the tool, avoiding the interference of the two hands of the staff.

[0011] Preferably, the first column is provided with a first anti-slip cover on the outside, and the second column is provided with a second anti-slip cover on the outside. Both the first anti-slip cover and the second anti-slip cover can effectively reduce the slippage caused by sweat or grease on the hands, and reduce the risk of accidental injury to workers or damage to auto parts caused by the tool falling.

[0012] Preferably, the first column is provided with a first limiting portion and a second limiting portion, and the two ends of the first anti-slip sleeve are respectively abutted against the first limiting portion and the second limiting portion; the second column is provided with a third limiting portion and a fourth limiting portion, and the two ends of the second anti-slip sleeve are respectively abutted against the third limiting portion and the fourth limiting portion. The first limiting portion and the second limiting portion can limit the sliding of the first anti-slip sleeve in the axial direction of the first column, and the third limiting portion and the fourth limiting portion can limit the sliding of the second anti-slip sleeve in the axial direction of the second column, so as to avoid the first anti-slip sleeve and the second anti-slip sleeve from suddenly sliding or falling off during the use of the tool, so as to facilitate the staff to control the tool more stably.

[0013] Preferably, the first anti-slip cover and the second anti-slip cover are provided with a plurality of first grooves and a plurality of second grooves on their exteriors, respectively, a first protrusion is formed between two adjacent first grooves, and a second protrusion is formed between two adjacent second grooves. In this way, the roughness of the surfaces of the first anti-slip cover and the second anti-slip cover can be increased, further reducing the risk of the staff's hands slipping, and the outer surfaces of the first anti-slip cover and the second anti-slip cover are cylindrical surfaces as a whole, and neither of them will cause obvious impact on the staff's hands when rolling on the hands of the staff.

[0014] Wherein, the first anti-slip cover and the second anti-slip cover can be made of sponge, silicone, rubber or other materials with anti-slip function. Preferably, the first anti-slip cover and the second anti-slip cover are both made of rubber material. Rubber has good anti-slip performance and high wear resistance, and can withstand long-term use without being easily worn, which is conducive to improving the life of the first anti-slip cover and the second anti-slip cover. In addition, the rubber material is soft and elastic, and can provide a comfortable grip.

[0015] The first cutter head and the second cutter head can be two of a cross head, an equilateral hexagonal head, a square head, a triangular head, a Y-shaped head, etc. In one preferred solution, the first cutter head is an equilateral hexagonal head, and the second cutter head is a cross head. It should be noted that both the cross head and the equilateral hexagonal head are prior art, so the specific structures of the two are not described in detail here.

[0016] Preferably, the first column, the connecting piece and the second column are all made of stainless steel. The first column, the connecting piece and the second column made of stainless steel have high strength and hardness, good corrosion resistance and long service life.

[0017] Preferably, the first column and the second column are both welded to the connecting piece. The welding connection can provide a higher connection strength between the first / second column and the connecting piece, ensuring that the tool is not prone to loosening or breaking during use. Moreover, the welding connection method can simplify the structure of the tool, reduce parts, and reduce manufacturing costs.

[0018] The beneficial effects of the utility model are as follows: the tool is provided with two cutter heads with different structures, which can be used for adjusting the light axis of the headlights of two types of vehicles, thereby reducing the switching frequency of the tool; during the use of the tool, there is no need to move the first / second cutter head away from the position of the adjusting screw, and the continuous rotation function of the tool can be achieved by continuously shaking the first column or the second column. The rotation and operation are more convenient and flexible, which can reduce the hand movements of the staff and reduce the fatigue of the wrist and arms, which is conducive to shortening the working hours and improving the adjustment efficiency of the light axis of the car headlights.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0025] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0026] Example 1

[0027] like Figure 1 The tool shown is a tool for adjusting the light axis of a car headlight, which includes a first cylinder 1, and a first cutter head 2 is provided at one end of the first cylinder 1; the tool also includes a connecting piece 3 and a second cylinder 4, and the other end of the first cylinder 1 is connected to the connecting piece 3; one end of the second cylinder 4 is provided with a second cutter head 5 with a structure different from that of the first cutter head 2, and the other end of the second cylinder 4 is connected to the connecting piece 3, and the axes of the first cylinder 1 and the second cylinder 4 are parallel to each other.

[0028] The working principle or workflow of this embodiment is as follows: when adjusting the light axis of the headlight of one type of car, after the first cutter head 2 is connected to the adjusting screw of the light axis of the car headlight, the operator can hold the first column 1 with one hand to keep the axis of the first column 1 in the same straight line, and hold the second column 4 with the other hand, and shake the second column 4 with the first column 1 as the rotation axis, so that the whole tool rotates around the axis of the first column 1, thereby screwing and adjusting the adjusting screw of the light axis of the car headlight. When it is necessary to adjust the light axis of the headlight of another type of car, the second cutter head 5 is replaced and the adjusting screw of the car of the same type is screwed in the same way.

[0029] The beneficial effects of this embodiment are as follows: the tool is provided with two cutter heads with different structures, which can be used to adjust the light axis of the headlights of two types of vehicles, thereby reducing the switching frequency of the tool and shortening the operation time; the tool does not need to move the first / second cutter head away from the position of the adjusting screw during use, and the tool can be continuously rotated by continuously shaking the first column or the second column, and its rotation and operation are more convenient and flexible, which can reduce the hand movements of the staff and reduce the fatigue of the wrist and arms, which is conducive to shortening the operation time and improving the adjustment efficiency of the light axis of the car headlights.

[0030] Example 2

[0031] This embodiment further describes the connector 3 based on the embodiment 1. Figure 1 and Figure 2 As shown, the connecting member 3 includes a first straight rod portion 301, an oblique rod portion 302, and a second straight rod portion 303. The axis of the first straight rod portion 301 and the axis of the second straight rod portion 303 are parallel to each other, and one end of the first straight rod portion 301 and one end of the second straight rod portion 303 are respectively connected to the two ends of the oblique rod portion 302; the first column 1 is coaxially connected to the first straight rod portion 301, and the second column 4 is coaxially connected to the second straight rod portion 303. Such a connecting member 3 has a simple structure, is light in weight, and is easy to process.

[0032] Furthermore, an obtuse angle is formed between the axis of the oblique rod 302 and the axis of the first straight rod 301, and the distance between the end of the first column 1 and the end of the second column 4 is greater than the sum of the lengths of the first column 1 and the second column 4. It is understandable that when an obtuse angle is formed between the axis of the oblique rod 302 and the axis of the first straight rod 301, an obtuse angle is also formed between the axis of the second straight rod 303 and the axis of the oblique rod 302. In this way, a certain distance can be maintained between the first column 1 and the second column 4 in the axial direction of one of the two, so that the two hands of the staff can be kept at a certain distance when using the tool, and the two hands of the staff are prevented from interfering with each other.

[0033] The other features, working principles and beneficial effects of this embodiment are consistent with those of Embodiment 1.

[0034] Example 3

[0035] This embodiment is based on embodiment 2. Figure 1 and Figure 3 As shown, the first column 1 is covered with a first anti-skid cover 6, and the second column 4 is covered with a second anti-skid cover 7. Both the first anti-skid cover 6 and the second anti-skid cover 7 can effectively reduce the slippage caused by sweat or grease on the hands, and reduce the risk of accidental injury to workers or damage to automobile parts caused by the tool falling.

[0036] Furthermore, the first column 1 is provided with a first limiting portion 101 and a second limiting portion 102, and the two ends of the first anti-slip sleeve 6 are respectively abutted against the first limiting portion 101 and the second limiting portion 102; the second column 4 is provided with a third limiting portion 401 and a fourth limiting portion 402, and the two ends of the second anti-slip sleeve 7 are respectively abutted against the third limiting portion 401 and the fourth limiting portion 402. The first limiting portion 101 and the second limiting portion 102 can limit the sliding of the first anti-slip sleeve 6 in the axial direction of the first column 1, and the third limiting portion 401 and the fourth limiting portion 402 can limit the sliding of the second anti-slip sleeve 7 in the axial direction of the second column 4, so as to avoid the first anti-slip sleeve 6 and the second anti-slip sleeve 7 from suddenly sliding or falling off during the use of the tool, so that the staff can control the tool more stably.

[0037] Furthermore, the first anti-slip cover 6 and the second anti-slip cover 7 are respectively provided with a plurality of first grooves 601 and a plurality of second grooves 701 on their exteriors, a first protrusion 602 is formed between two adjacent first grooves 601, and a second protrusion 702 is formed between two adjacent second grooves 701. In this way, the roughness of the surface of the first anti-slip cover 6 and the second anti-slip cover 7 can be increased, and the risk of the staff's hands slipping can be further reduced. Moreover, the outer surfaces of the first anti-slip cover 6 and the second anti-slip cover 7 are cylindrical surfaces as a whole, and neither of them will cause obvious impact on the staff's hands when rolling on the hands of the staff.

[0038] Furthermore, the first anti-slip cover 6 and the second anti-slip cover 7 are both made of rubber material. Rubber has good anti-slip performance and high wear resistance, and can withstand long-term use without being easily worn, which is conducive to improving the life of the first anti-slip cover 6 and the second anti-slip cover 7. In addition, the rubber material is soft and elastic, and can provide a comfortable grip.

[0039] Specifically, the first cutter head 2 is an equilateral hexagonal head, and the second cutter head 5 is a cross head. It should be noted that both the cross head and the equilateral hexagonal head are prior art, so the specific structures of the two are not described in detail here.

[0040] Furthermore, the first column 1, the connecting piece 3 and the second column 4 are all made of stainless steel. The first column 1, the connecting piece 3 and the second column 4 made of stainless steel have high strength and hardness, good corrosion resistance and long service life.

[0041] Furthermore, the first column 1 and the second column 4 are both welded to the connecting member 3. The welding connection can provide a high connection strength between the first / second column and the connecting member 3, ensuring that the tool is not prone to loosening or breaking during use. Moreover, the welding connection method can simplify the structure of the tool, reduce parts, and reduce manufacturing costs.

[0042] The other features, working principles and beneficial effects of this embodiment are consistent with those of Embodiment 2.

[0043] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description, and it is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
