Technical Field
[0001] This utility model relates to the field of borehole inner diameter detection technology, and in particular to a portable rapid borehole inner diameter detection device. Background Technology
[0002] The rapid bore diameter detection device is a key measuring tool that can quickly and accurately measure the inner diameter of a hole, providing reliable data support for product quality control, production process monitoring, and subsequent process adjustments.
[0003] Traditional rapid hole diameter testing often relies on the classic measuring tool, the micrometer. When using it, the operator holds the micrometer and places it at the location of the part to be tested. Then, the measuring end of the micrometer is slowly inserted into the inner hole of the part. Subsequently, the operator slowly and evenly adjusts the micrometer, gradually moving the two measuring ends away from each other until they are in close contact with the inner wall of the part. Once the measuring ends are in stable contact with the inner wall, the operator can quickly and intuitively understand the inner hole diameter of the part by observing the distance scale between the two ends on the micrometer. However, traditional micrometers for rapid bore diameter measurement are often slender and smooth during transport. When carried by a person, most of the micrometer's structure is exposed to the external environment, making it prone to accidental collisions with passing objects. The impact force from these collisions can cause the micrometer to slip and fall to the ground, resulting in damage or deformation. Furthermore, because the micrometer is a one-piece design, it requires complete replacement and repair during later maintenance, significantly increasing the cost of use. Utility Model Content
[0004] To overcome the problems of existing micrometers for rapid internal diameter measurement, which are typically long and thin with smooth surfaces, when carried by personnel, not only is most of the micrometer's structure exposed to the external environment, but it is also prone to accidental collisions with passing objects. The impact force from these collisions can easily cause the micrometer to slip and fall to the ground, resulting in damage or deformation. Furthermore, since the micrometer is a one-piece design, it requires complete replacement and repair during later maintenance, which greatly increases the cost of use.

The handle makes it easy for personnel to carry, and the outer shell and cover in the protective component can isolate the detection component from the external environment during carrying. At the same time, the detection component is located in the inner cavity of the filled foam. The filling foam is elastic and can buffer external impact forces, further protecting the detection component from damage, thereby reducing the possibility of device damage due to collision. Furthermore, the scale plate and sliding sleeve of the detection component are modularly movable, so there is no need to replace the whole unit when it wears out, which greatly reduces the cost of use.

The buckle is fixedly connected to both sides of the front side of the cover, and the latch is fixedly connected to both sides of the front side of the outer casing.
[0009] Preferably, a rubber pad is fixedly connected to the top of the sliding sleeve, and a finger groove is provided on the top of the rubber pad.
[0010] Preferably, a slide bar is fixedly connected to the inner cavity of the sliding sleeve, and a sliding groove is provided at the bottom of the scale plate. The slide bar is located in the inner cavity of the sliding groove and is slidably connected to the inner cavity of the sliding groove.
[0011] Preferably, the fastening assembly includes a threaded sleeve, a screw threaded into the inner cavity of the threaded sleeve, and an anti-slip pad fixedly connected to one end of the screw.
[0012] Preferably, the threaded sleeve is fixedly connected to the front of the sliding sleeve, one end of the screw passes through the threaded sleeve and the sliding sleeve and extends into the inner cavity of the sliding sleeve, the anti-slip pad is located in the inner cavity of the sliding sleeve, and one side of the sliding sleeve is in contact with the scale plate.
[0013] The beneficial effects of this utility model are as follows: the handle makes it easy for personnel to carry, and the outer shell and cover in the protective component can isolate the detection component from the external environment during carrying. At the same time, the foam filling provides fixation and protection for the detection component, effectively preventing damage from collisions during carrying and ensuring the safety of the detection component. Furthermore, the scale plate and sliding sleeve of the detection component are modularly movable, so there is no need to replace the whole component when it wears out, which greatly reduces the cost of use.

Detailed Implementation
[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0017] Example 1 Please see Figure 1 , Figure 2 , Figure 3 and Figure 4This utility model provides an embodiment of a portable rapid hole inner diameter detection device, comprising: a protective component 100, including an outer shell 110, a cover 120 hinged to the top of the outer shell 110, a filling foam 130 fixedly connected to the bottom of the inner cavity of the outer shell 110, and a handle 111 fixedly connected to the front of the outer shell 110 and the cover 120; and a detection component 200, including a scale plate 210, a sliding sleeve 220 sleeved on the surface of the scale plate 210, a first contact end 230 fixedly connected to the left side of the back of the scale plate 210, a second contact end 240 fixedly connected to the left side of the sliding sleeve 220, and a fastening component 250 disposed on the front of the sliding sleeve 220. The detection component 200 is located in the inner cavity of the filling foam 130 and is movably connected to the inner cavity of the filling foam 130. The scale plate 210 penetrates the inner cavity of the sliding sleeve 220 and is slidably connected to the inner cavity of the sliding sleeve 220.
[0018] During operation, the detection component 200 is first placed inside the outer casing 110, where the foam 130 cavity is filled. Personnel can then carry the detection component 200 to the desired testing location via the handle 111. During transport, the outer casing 110 and the cover 120 isolate the detection component 200 from the external environment. The elastic foam 130 cushions external impacts, further protecting the detection component 200 from damage and reducing the likelihood of damage due to collisions, significantly improving safety during transport. Upon arrival at the location, the latches and buckles of the locking element 121 are opened, the cover 120 is opened, and the detection component 200 is removed from the foam 130 cavity. During measurement, the first contact of the detection component 200 is... The first contact end 230 and the second contact end 240 are placed into the hole to be tested. The first contact end 230 contacts one side of the inner wall of the hole. Then, the sliding sleeve 220 is slid until the second contact end 240 contacts the inner wall of the hole. By rotating the screw 252 in the fastening assembly 250, the screw 252 rotates in the thread of the screw sleeve 251, pushing the anti-slip pad 253 to move towards the scale plate 210 until the anti-slip pad 253 is in close contact with the scale plate 210, generating sufficient friction to fix the sliding sleeve 220 on the scale plate 210, preventing the sliding sleeve 220 from sliding and affecting the accuracy of the measurement data. Finally, by reading the scale on the scale plate 210, the distance between the first contact end 230 and the second contact end 240, i.e., the inner diameter of the hole, can be seen intuitively, thus realizing the detection operation.
[0019] Example 2 Please see Figures 1-5The outer casing 110 and the cover 120 are provided with locking members 121. Locking members 121 include buckles and latches. The latches are fixedly connected to both sides of the front of the cover 120, and the buckles are fixedly connected to both sides of the front of the outer casing 110. The top of the sliding sleeve 220 is fixedly connected with a rubber pad, and the top of the rubber pad is provided with a finger groove. The inner cavity of the sliding sleeve 220 is fixedly connected with a slide bar 221. The bottom of the scale plate 210 is provided with a slide groove 211. The slide bar 221 is located in the inner cavity of the slide groove 211 and is slidably connected to the inner cavity of the slide groove 211.
[0020] The locking element 121 consists of a latch and a buckle, which are respectively fixed to the front sides of the outer casing 110 and the cover 120. This design makes the opening and closing of the outer casing 110 and the cover 120 very convenient, while ensuring the firmness after closing. When carrying the device, it can effectively prevent the cover 120 from being accidentally opened, avoiding the internal detection component 200 from falling out and being damaged. When the detection component 200 needs to be used, the cover 120 can be quickly opened for access. The rubber pad on the top of the sliding sleeve 220 has a certain degree of elasticity and anti-slip properties, and the finger groove on the top is ergonomically designed. When the operator slides the sliding sleeve 220 to perform the measurement... During measurement, the fingers can be comfortably placed in the finger groove, increasing the friction between the hand and the sliding sleeve 220, making it easier to control the sliding of the sliding sleeve 220 more accurately and making the measurement operation more stable. The sliding strip 221 is fixed in the inner cavity of the sliding sleeve 220, and the sliding groove 211 is opened at the bottom of the scale plate 210. The sliding strip 221 slides in the sliding groove 211. This structure ensures the smoothness and straightness of the sliding sleeve 220 on the scale plate 210, reduces the shaking and deviation during the sliding process, and makes the measurement results more accurate and reliable.
[0021] Example 3 Please see Figure 3 , Figure 4 and Figure 6 The fastening assembly 250 includes a threaded sleeve 251, a screw 252 threaded into the inner cavity of the threaded sleeve 251, and an anti-slip pad 253 fixedly connected to one end of the screw 252. The threaded sleeve 251 is fixedly connected to the front of the sliding sleeve 220. One end of the screw 252 passes through the threaded sleeve 251 and the sliding sleeve 220 and extends into the inner cavity of the sliding sleeve 220. The anti-slip pad 253 is located in the inner cavity of the sliding sleeve 220, and one side of the sliding sleeve 220 is in contact with the scale plate 210.
[0022] The fastening assembly 250, through the cooperation of the threaded sleeve 251, the screw 252, and the anti-slip washer 253, can securely fix the sliding sleeve 220 at a specific position on the scale plate 210. When measuring the inner diameter of the hole, after the sliding sleeve 220 drives the second contact end 240 to a suitable position in contact with the inner wall of the hole, the screw 252 is rotated. Utilizing the principle of thread transmission, the screw 252 moves within the threaded sleeve 251, pushing the anti-slip washer 253 into close contact with the scale plate 210, generating sufficient friction to prevent the sliding sleeve 220 from slipping, thereby ensuring the accuracy of the measurement data. At the same time, the anti-slip washer 253 is made of a soft and elastic material. When in contact with the scale plate 210, it not only increases the friction but also prevents the screw 252 from directly contacting the scale plate 210 and causing wear, thus protecting the scale plate 210 and extending the service life of the detection assembly 200.
[0023] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
