Description

Technical Field

[0001] This utility model relates to the field of feeler gauge technology, specifically a feeler gauge calibration device. Background Technology

[0002] A feeler gauge is a tool mainly used for measuring gaps and distances. It is widely used in the process of measuring the gaps between parts. A flat feeler gauge is composed of thin steel sheets with a thickness of 0.05-1.00 mm. It is simple to operate and has a wide range of applications.

[0003] In response, Chinese patent application number CN202420162359.8 discloses a feeler gauge that is easy to store, including a feeler gauge and a U-shaped mounting shell. The feeler gauge is rotatably mounted on a hinge shaft, which is located at one end of the opening of the mounting shell. A protective shell, also U-shaped, is fitted over the outside of the mounting shell, with its open end rotatably mounted on the hinge shaft. A locking mechanism is provided at the end of the protective shell, and Velcro is provided on the protective shell. A storage stop is detachably mounted on the side of the protective shell. After using the feeler gauge, the storage stop is inserted, forming a storage box with the protective shell. The mounting shell and any loose feeler gauge are then stored inside the protective shell. The locking mechanism prevents relative rotation between the mounting shell and the protective shell, and the Velcro is wrapped around the outer layer of the protective shell to secure the feeler gauge. This reduces the likelihood of bending or deformation of the feeler gauge during transport and prevents damage to the feeler gauge.

[0004] The device can protect the feeler gauge by setting a protective shell. However, in actual use, the slight bending of the feeler gauge body is not very obvious and therefore difficult to detect. In subsequent use, when the two feeler gauge bodies are used together, the ends of the two feeler gauge bodies will be separated in a figure-eight shape, which will affect the judgment of the results.

[0005] Therefore, in order to solve the above problems, a feeler gauge calibration device is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a feeler gauge calibration device to solve the problem mentioned in the background art that the device can protect the feeler gauge by setting a protective shell, but in actual use, the feeler gauge body is not very obvious when it is slightly bent, so it is difficult to detect. In subsequent use, when the two feeler gauge bodies are used in close contact, the ends of the two feeler gauge bodies will be separated in a figure-eight shape, which will affect the judgment of the result.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a feeler gauge calibration device, comprising: a protective shell, a hinge shaft installed at the left end of the protective shell, a ruler body installed on the inner side of the protective shell, and a sliding groove formed on the right end surface of the protective shell;

[0008] The inner side of the protective shell is equipped with a verification structure, which includes a fixing block. The fixing block is fixedly installed on the right side of the inner side of the protective shell, and the top surface of the fixing block is provided with a verification groove.

[0009] A positioning sleeve is slidably installed on the inner side of the groove.

[0010] Preferably, the thickness of the ruler body decreases from top to bottom, and the length of the ruler body decreases from top to bottom.

[0011] Preferably, the ruler pieces are fitted together, and the ends of the ruler pieces are engaged inside the calibration slot.

[0012] Preferably, the number of ruler pieces is the same as the number of calibration slots, and the size of the ruler pieces corresponds one-to-one with the size of the calibration slots.

[0013] Preferably, the surface of the positioning sleeve is provided with a rubber pad, and the positioning sleeve is fitted on the outside of the ruler body.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the ruler body of this utility model has different lengths, and with the multiple sets of calibration slots on the fixing block, the shape of the ruler body can be detected. When the ruler body is bent and deformed, the ruler body will be stuck on the protective shell, the fixing block or an adjacent set of ruler bodies, and thus cannot be stored in the calibration slot. The shape of the ruler body can be quickly detected. The structure is simple and the practicality is strong.

[0015] This invention features a verification structure and a positioning sleeve. Pulling the positioning sleeve moves it from the left end to the right end inside the groove, thus removing it from the outside of the ruler body and releasing it from the protective shell. The ruler body can then be removed from the protective shell for use. For storage, the ruler bodies are overlapped and screwed inside the protective shell. Pulling the positioning sleeve moves it from the right end to the left end inside the groove, securing it to the outside of the ruler body and fixing it to the protective shell. The inner side of the shell is for carrying and transferring. When the straightness of the ruler body needs to be checked, the protective shell is placed vertically with the groove facing upward. The ruler body is pulled out from the protective shell and then lowered in order from thickest to thinnest. When the ruler body bends and deforms, the end of the ruler body will extend to the upper side of the protective shell or fixing block due to bending. Therefore, the end of the ruler body will be stuck on the top surface of the protective shell or fixing block when it is lowered and cannot be moved stably into the inspection groove. The straightness of the ruler body can then be checked. The operation is convenient, the structure is simple, and the practicality is strong. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 An embodiment of a feeler gauge calibration device provided by this utility model:

[0024] The protective shell 1, hinge shaft 11 and ruler body 12 used in this application are products that can be purchased directly on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0025] A feeler gauge calibration device includes: a protective housing 1, a hinge shaft 11 installed at the left end of the protective housing 1, a ruler body 12 installed on the inner side of the protective housing 1, and a sliding groove 13 formed on the right end surface of the protective housing 1.

[0026] A calibration structure 2 is installed on the inner side of the protective housing 1. The calibration structure 2 includes a fixing block 21, which is fixedly installed on the right side of the inner side of the protective housing 1. A calibration groove 22 is provided on the top surface of the fixing block 21.

[0027] A positioning sleeve 3 is slidably installed on the inner side of the slide groove 13. The length of the ruler body 12 is different. With the cooperation of multiple sets of inspection grooves 22 on the fixing block 21, the shape of the ruler body 12 can be detected. When the ruler body 12 is bent and deformed, the ruler body 12 will be stuck on the protective shell 1, the fixing block 21 or an adjacent set of ruler bodies 12, and thus cannot be stored inside the inspection groove 22. The shape of the ruler body 12 can be quickly inspected. The structure is simple and the practicality is strong.

[0028] Furthermore, the thickness of the ruler body 12 decreases from top to bottom, and the length of the ruler body 12 decreases from top to bottom. The ruler body 12 with different thicknesses can be used in different application scenarios, thus improving the practicality of the device.

[0029] Furthermore, the ruler body 12 is fitted together, and the end of the ruler body 12 is locked inside the calibration groove 22. The calibration groove 22 provides protection for the end of the ruler body 12 to prevent wear.

[0030] Furthermore, the number of ruler body 12 is the same as the number of inspection slots 22, and the size of the ruler body 12 corresponds one-to-one with the size of the inspection slot 22. When the ruler body 12 is bent, it cannot be stored in the inspection slot 22, and the deformation of the ruler body 12 can be determined.

[0031] Furthermore, the surface of the positioning slide sleeve 3 is provided with a rubber pad. The positioning slide sleeve 3 is sleeved on the outside of the ruler body 12. The rubber pad can increase the friction between the positioning slide sleeve 3 and the slide groove 13, prevent the positioning slide sleeve 3 from shifting, and ensure the positioning effect of the ruler body 12.

[0032] Working principle: When in use, pull the positioning sleeve 3 so that the positioning sleeve 3 moves from the left end to the right end inside the slide groove 13, and the positioning sleeve 3 can be moved away from the outside of the ruler body 12, which can release the fixation of the ruler body 12 inside the protective shell 1, and the ruler body 12 can be pried out from the inside of the protective shell 1 for use.

[0033] When storing, overlap the ruler body 12 and rotate it to the inside of the protective shell 1. Pull the positioning sleeve 3 so that the positioning sleeve 3 moves from the right end to the left end inside the groove 13. The positioning sleeve 3 can then be fitted onto the outside of the ruler body 12, thus fixing the ruler body 12 to the inside of the protective shell 1 for carrying and transfer.

[0034] When the straightness of the ruler body 12 needs to be checked, the protective shell 1 is placed vertically with the slide groove 13 facing upward. The ruler body 12 is pulled out from the protective shell 1 and then lowered in order from thickest to thinnest. When the ruler body 12 bends and deforms, the end of the ruler body 12 will extend to the upper side of the protective shell 1, the fixing block 21, or an adjacent group of ruler bodies 12 due to bending. Therefore, the end of the ruler body 12 will be stuck on the top surface of the protective shell 1 or the fixing block 21 when it is lowered, and cannot move stably into the inspection groove 22. The straightness of the ruler body 12 can then be checked. The operation is convenient, the structure is simple, and the practicality is strong.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
