Description

Technical Field

[0001] This utility model relates to the field of measuring device technology, specifically a door drag chain gap measuring device. Background Technology

[0002] Door cable chains play a crucial role in vehicle door systems, providing cable support and ensuring safe movement during door opening and closing. However, the size of the gap between the door cable chain and the door directly affects the performance and safety of the entire door system. If the gap is too small, the door cable chain can easily interfere with and pull on the door during opening and closing, potentially breaking the internal circuitry and seriously compromising driving safety.

[0003] Currently, measuring door chain drag chains faces numerous challenges. On one hand, door chain drag chains have many measurement parameters, and the measurement gaps are located outside a plane, resulting in extremely limited measurement space, making it impossible to fit conventional measuring tools for accurate measurements. On the other hand, current methods primarily rely on visual inspection to estimate gap sizes, which has serious limitations and significantly impacts measurement accuracy. In practice, if visual inspection reveals parameters outside the required range, the door chain drag chain needs adjustment. After adjustment, the parameters are rechecked; if still unsatisfactory, further adjustments are required, repeating this "adjust-measure-adjust" process. This not only consumes significant time and manpower but also severely affects the efficiency and accuracy of measurement and adjustment, failing to meet the demands of modern vehicle door systems for high-quality, high-efficiency measurements. Utility Model Content

[0004] In order to overcome the problems existing in the prior art, the purpose of this utility model is to provide a door drag chain gap measuring device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a door drag chain gap measuring device, comprising:

[0006] Handheld lever and measuring block;

[0007] The measuring block is provided with a measuring part and a fixing part. The fixing part is detachably connected to the hand handle. The measuring part is provided with measuring steps of different thicknesses. The measuring steps of different thicknesses are inserted into the gap between the car door and the cable chain to measure the gap.

[0008] Main working principle: This door cable chain clearance measuring device mainly consists of two parts: a handheld lever and a measuring block. The measuring block is further divided into a measuring section and a fixing section. The fixing section is responsible for the detachable connection with the handheld lever. This design allows the measuring block to be easily attached and detached from the handheld lever, facilitating the replacement of the measuring block according to different measurement needs, or for maintenance, calibration, and other operations. The measuring section is the core area of ​​the entire device that enables its measuring function. It is equipped with measuring steps of different thicknesses, which are key elements for accurately measuring the clearance between the door and the cable chain.

[0009] Before conducting measurements, operators need to select appropriate measuring blocks based on the actual measurement scenario and requirements, and install them onto the handheld rod via the fixing part. Ensure the connection is secure and reliable to prevent the measuring blocks from loosening or falling off during measurement, which could affect the accuracy and safety of the measurement. Simultaneously, a visual inspection of the measuring device should be performed to confirm that the measuring steps of the measuring part are free from damage, wear, or deformation, and that the handheld rod is free from bending, breakage, or other abnormalities, ensuring the device is in good working order.

[0010] The operator, holding the measuring rod with the measuring block installed, slowly and accurately inserts the measuring step of the measuring unit into the gap between the door and the cable chain. During insertion, the measuring device must be kept stable to avoid inaccurate measurements or damage to the cable chain and door due to shaking or excessive force. As the measuring step is gradually inserted into the gap, the contact between the cable chain and the measuring step is observed. Because the measuring unit has measuring steps of different thicknesses, when the cable chain makes contact with a measuring step of a specific thickness, it indicates that the thickness of that measuring step is equal to the size of the gap between the door and the cable chain. This is because the measuring steps are manufactured to specific precision and specifications, and their thickness represents different gap size standards. Once the contact between the cable chain and a particular measuring step is determined, the operator can determine the size of the gap between the door and the cable chain based on the thickness value of that measuring step. After measurement, the operator removes the measuring device from the gap and records the measured gap value. The measurement results are then compared with the pre-set standard range for door and cable chain gaps. If the measured value is within the standard range, it means that the gap between the door and the cable chain meets the requirements and the door system can operate normally. If the measured value exceeds the standard range, it indicates that the gap is too small or too large, which may affect the normal movement of the cable chain, or even cause problems such as interference or wear between the cable chain and the door. The door or cable chain needs to be adjusted in time to ensure the safety and reliability of the door system.

[0011] Preferably, the measuring part has a bonding surface on both sides and measuring steps of different thicknesses on both sides, and the number of steps of the measuring steps is not less than two. The bonding surface is bonded to the car door, and the measuring part extends into the gap. When the cable chain contacts any of the measuring steps, the measurement can be completed.

[0012] Preferably, the measuring part extends along a straight line away from the fixing part, and the thickness of the measuring step gradually decreases along the direction away from the fixing part, and the contact surface of the measuring part is in contact with the door bracket.

[0013] Preferably, the measuring part extends to both sides of the fixing part, and the measuring parts on both sides are respectively provided with two measuring steps of different thicknesses.

[0014] Preferably, the bonding surface is arc-shaped and is bonded to the door hinge of the vehicle door.

[0015] Preferably, the measuring part extends in a direction away from the fixing part and is curved, and the contact surface is in contact with the door stem of the car door.

[0016] Preferably, the thickness of the measuring step gradually decreases along the direction away from the fixing part.

[0017] Preferably, the fixing part is provided with a threaded hole, and the fixing part is connected to the hand handle through the threaded hole.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention features measuring steps of varying thicknesses in its measuring section. During measurement, when a measuring step of a specific thickness contacts the cable chain, the gap between the door and the cable chain can be directly and accurately determined. Compared to traditional visual estimation methods, this avoids errors caused by human factors and provides reliable data support for the design and adjustment of the door system. The measuring steps of different thicknesses form a clear quantitative standard, ensuring consistent and repeatable measurement results. Regardless of the operator, as long as the correct operating method is followed, the same gap value can be obtained, which is beneficial for standardized management and quality control of door cable chain gaps. The device is equipped with a handheld lever, allowing operators to conveniently hold and measure without complex installation and debugging processes. In the confined space inside a car door, the handheld design allows operators to flexibly adjust the measuring position and angle, quickly completing the measurement task. For example, when inspecting door cable chains in a repair shop, repair personnel can use this device to quickly measure gaps in different areas, improving work efficiency. The measuring block's fixing part and the handheld lever are detachably connected. This not only facilitates the replacement of measuring blocks of different specifications to meet different measurement needs, but also makes it convenient to maintain and calibrate the measuring blocks. When the measuring block is worn or damaged, a new measuring block can be replaced in a timely manner to ensure measurement accuracy; at the same time, regular calibration of the measuring block is also more convenient and quick.

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0027] Example 1

[0028] This embodiment discloses a door drag chain clearance measuring device, such as... Figures 1-3As shown, the device includes a handheld lever 1 and a measuring block 2. The measuring block 2 is further subdivided into a measuring section 20 and a fixing section 21. The fixing section 21 is designed to be detachably connected to the handheld lever 1. This design allows the measuring block 2 to be easily attached and detached from the handheld lever 1, facilitating the replacement of the measuring block 2 according to different measurement needs, or the maintenance and calibration of the measuring block 2. The measuring section 20 is the core area of ​​the entire device for realizing the measurement function. It is provided with measuring steps 200 of different thicknesses. These measuring steps 200 are key elements for accurately measuring the gap between the car door and the cable chain.

[0029] Before conducting measurements, the operator needs to select a suitable measuring block 2 based on the actual measurement scenario and requirements, and install it onto the handheld rod 1 via the fixing part 21. Ensure the connection is secure and reliable to prevent the measuring block 2 from loosening or falling off during the measurement process, which could affect the accuracy and safety of the measurement. Simultaneously, a visual inspection of the measuring device should be performed to confirm that the measuring steps 200 of the measuring part 20 are free from damage, wear, or deformation, and that the handheld rod 1 is free from bending, breakage, or other abnormalities, ensuring the device is in good working order.

[0030] The operator holds the handheld lever 1 with the measuring block 2 installed and slowly and accurately inserts the measuring step 200 of the measuring unit 20 into the gap between the car door and the cable chain. During insertion, the measuring device must be kept stable to avoid inaccurate measurements or damage to the cable chain and car door due to shaking or excessive force. As the measuring step 200 gradually penetrates the gap, the contact between the cable chain and the measuring step 200 is observed. Since the measuring unit 20 has measuring steps 200 of different thicknesses, when the cable chain makes contact with a measuring step 200 of a specific thickness, it indicates that the thickness of that measuring step 200 is equal to the size of the gap between the car door and the cable chain. This is because the measuring step 200 is manufactured to a certain precision and specification, and its thickness represents different gap size standards. Once it is determined that the cable chain is in contact with a certain measuring step 200, the operator can determine the size of the gap between the car door and the cable chain based on the thickness value of that measuring step 200. After the measurement is completed, the operator removes the measuring device from the gap and records the measured gap value. The measurement results are compared according to the pre-set standard range for the door cable chain clearance. If the measured value is within the standard range, it means that the clearance between the door and the cable chain meets the requirements and the door system can operate normally. If the measured value exceeds the standard range, it indicates that the clearance is too small or too large, which may affect the normal movement of the cable chain, or even cause problems such as interference or wear between the cable chain and the door. The door or cable chain needs to be adjusted in time to ensure the safety and reliability of the door system.

[0031] In some optional embodiments, the measuring part 20 has a mating surface 201 on each side and measuring steps 200 of different thicknesses and at least two steps on each side. During measurement, the mating surface 201 of the measuring part 20 is first tightly fitted to the surface of the car door to ensure that the relative position of the measuring device and the car door is fixed. Then, the measuring part 20 is slowly inserted into the gap between the car door and the cable chain. As the measuring part 20 goes deeper, the measuring steps 200 of different thicknesses enter the gap in sequence. When the cable chain contacts any measuring step 200, it indicates that the thickness of the measuring step 200 matches the gap size. The gap size can then be determined based on the thickness of this measuring step 200, thus completing the measurement.

[0032] In some alternative embodiments, such as Figure 1 As shown, the measuring part 20 extends along a straight line away from the fixing part 21, and the thickness of the measuring step 200 gradually decreases in this direction, with the contact surface 201 contacting the door bracket. The operator accurately attaches the contact surface 201 of the measuring part 20 to the door bracket, providing a stable reference for measurement. Then, the measuring part 20 is inserted linearly into the gap between the door and the cable chain. Due to the gradual change in thickness of the measuring step 200, during insertion, the thinner measuring step 200 passes directly through the gap, while the thicker measuring step 200 contacts it. By determining which measuring step 200 contacts the cable chain, the gap size can be accurately determined, and this linear extension and gradual thickness design facilitates accurate measurement in a specific direction.

[0033] In some alternative embodiments, such as Figure 3 As shown, the measuring part 20 extends to both sides of the fixing part 21, and each measuring part 20 on both sides is provided with two measuring steps 200 of different thicknesses. During operation, the appropriate measuring part 20 can be selected for measurement according to the specific position and direction of the gap between the door and the cable chain. The contact surface 201 of the selected measuring part 20 is attached to the corresponding part of the door, and then the measuring part 20 is inserted into the gap. When the cable chain contacts a certain measuring step 200 of the measuring part 20 on that side, the size of the gap can be determined according to the thickness of this measuring step 200, meeting the needs of different measurement scenarios.

[0034] In some optional embodiments, the contact surface 201 of the measuring part 20 is arc-shaped and fits against the door hinge of the vehicle door. Since the door hinge of a vehicle door is usually arc-shaped, designing the contact surface 201 of the measuring part 20 to be arc-shaped allows it to fit better against the door hinge, ensuring the relative position of the measuring device and the vehicle door is stable and reducing measurement errors. During measurement, the arc-shaped contact surface 201 is tightly fitted onto the door hinge, and then the measuring part 20 is inserted into the gap. The contact between the cable chain and the measuring step 200 improves the accuracy of gap measurement near the door hinge.

[0035] In some alternative embodiments, such as Figure 2As shown, the measuring part 20 extends in an arc shape in the direction opposite to the fixing part 21, and the contact surface 201 is in contact with the door stem of the vehicle door. The arc-shaped design of the measuring part 20 better adapts to the shape of the door stem, allowing the contact surface 201 to fit tightly with the door stem, providing a stable reference for measurement. During measurement, the contact surface 201 is attached to the door stem, and the measuring part 20 is inserted into the gap. As the measuring part 20 goes deeper, the cable chain will contact the measuring steps 200 of different thicknesses. The gap size is determined according to the thickness of the contacted measuring steps 200, thus achieving accurate measurement of complex gaps near the door stem.

[0036] In some optional embodiments, the thickness of the measuring step 200 gradually decreases along the direction away from the fixing part 21. During measurement, the contact surface 201 of the measuring part 20 is attached to the door frame, and the curved portion of the measuring part 20 is inserted into the gap between the door and the cable chain. Because the thickness of the measuring step 200 gradually changes, during insertion, the thinner measuring step 200 will pass directly through the gap, while the thicker measuring step 200 will contact it. As the gap changes, it will sequentially contact even thicker measuring steps 200. By determining which measuring step 200 the cable chain contacts, the gap size can be determined more accurately. This design facilitates more detailed measurements during the insertion of the curved measuring part 20 into the gap.

[0037] In some optional embodiments, the fixing part 21 is provided with a threaded hole 210, through which it connects to the handheld rod 1. This threaded connection method enables a detachable connection between the handheld rod 1 and the measuring block 2. During installation, the threaded end of the handheld rod 1 is screwed into the threaded hole 210 of the fixing part 21 of the measuring block 2, and the two are tightly connected by rotation, ensuring the stability of the device during measurement. During disassembly, the handheld rod 1 can be separated from the measuring block 2 by rotating it in the opposite direction, facilitating the replacement of the measuring block 2 or maintenance and cleaning of various parts of the device.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
