[0038] Embodiment 1

[0039] Existing cap height measuring heads, such as Figure 1 As shown, it includes a conical head 1', a contact 2' and a screw 3'. The small end of the conical head 1' is provided with a contact 2', and the contact 2' contacts the bottom wall of the bottle cap to measure the corresponding data of the corresponding point of the bottle cap measurement point. The large end of the conical head 1' is provided with a screw 3' threadedly connected to the bottle cap height measuring device. Since each bottle cap needs to be tested at least three times to obtain the final height data of each bottle cap, the detection workload is large and the efficiency is low.

[0040] In order to solve the above problems, this embodiment provides a bottle cap height measuring device, combined with Figure 2-Figure 4 As shown, the bottle cap height measuring device includes a body and a bottle cap height measuring head. An internal thread is provided on the connecting end of the body (not shown in the figure). The bottle cap height measuring head includes a connecting piece. The connecting piece includes a screw 31. The screw 31 cooperates with the internal thread to realize a detachable connection between the bottle cap height measuring head and the bottle cap height measuring device, which is convenient for replacing different types of bottle cap height measuring heads to adapt to the measurement of different types of bottle caps, and has good versatility.

[0041] Furthermore, if Figure 3 and Figure 4 As shown, the bottle cap height measuring head also includes a body 1 and a contact disk 2, one end of the contact disk 2 is arranged at one end of the body 1, a screw 31 is arranged at the other end of the body 1 away from the contact disk 2, a contact ring 21 is arranged at the edge of the end surface of the other end of the contact disk 2, the contact ring 21 is coaxially arranged with the contact disk 2, the diameter of the contact disk 2 is less than or equal to the diameter of the contact ring 21, the diameter of the contact ring 21 matches the diameter of the bottle cap, and the end surface of the contact ring 21 covers all the detection points of the bottle cap.

[0042] It can be understood that, in this embodiment, by setting the current point contact form contact to a surface contact form contact ring 21, the contact ring 21 and the contact plate 2 extend into the opening of the bottle cap until they abut against the bottom wall of the bottle cap. Only one measurement is needed to cover all the measuring points on the bottom wall of the bottle cap, thereby directly obtaining the maximum height without repeated measurements. The detection workload is greatly reduced and the efficiency is improved.

[0043] Specifically, Figure 3 As shown, the contact disc 2, the contact ring 21, the body 1 and the screw 31 are an integrated structure. The integrated structure has good integrity, high strength, and is not easy to deform. The connecting edge of the screw 31 and the body 1 and the connecting edge of the contact disc 2 and the body 1 are both provided with rounded corners, and the edge of the body 1 away from the contact disc 2 and the edge of the contact disc 2 away from the contact ring 21 are both provided with chamfers, so as to prevent the operator from being accidentally injured by the edges when adjusting the bottle cap height measuring head, and the safety is good.

[0044] For example, the diameter of the screw 31 of the present embodiment is 2.5mm, and the pitch is 0.45mm. In other embodiments, the diameter specification can also be 1.4mm, 1.7mm, 2m or 2.3mm, etc., which is not specifically limited in the present embodiment, but the caliber of the corresponding internal thread is adapted to maintain an adaptive relationship therewith. The length of the contact disc 2, the contact ring 21 and the body 1 in the axial direction of the present embodiment is 5mm, which can also be 4mm, 6mm, 7mm or 8mm, etc. in other embodiments, which is not specifically limited in the present embodiment, and can be replaced and debugged according to the model of the bottle cap. In addition, the diameter of the contact disc 2 and / or the contact ring 21 of the present embodiment is 30mm, which can also be 25mm, 28mm, 32mm or 35mm, etc. in other embodiments, which is not specifically limited in the present embodiment, and can be replaced and debugged according to the model of the bottle cap.

[0045] In another embodiment, Figure 4 As shown, in order to facilitate the bottle cap height measuring head to adapt to different types of bottle caps, the contact disk 2, the main body 1 and the connecting piece are an integrally formed structure, and the contact ring 21 is magnetically connected to the contact disk 2. By replacing the contact rings 21 of different sizes, the contact ring 21 matching the corresponding model can be adsorbed on the contact disk 2, thereby improving the application range of the bottle cap height measuring head. Compared with disassembly and replacement by screwing the screws 31, the convenience of matching the bottle cap height measuring head with the corresponding model of bottle cap is further improved.

[0046] In addition, the contact plate 2, the contact ring 21, the body 1 and the connecting piece are made of metal. The contact plate 2 and the contact ring 21 are preferably made of iron, which can be magnetized and maintain good magnetism, or nickel or cobalt, etc. The body 1 and the screw 31 are preferably made of stainless steel, which is not easy to rust and has good wear resistance.

An elastic member is provided inside the groove 321, one end of the elastic member abuts against the bottom wall of the groove 321, and the other end of the elastic member is provided with a block 323 slidably connected to the groove 321. The connecting rod 32 is inserted into the connecting end of the body, and a through hole 324 communicating with its inner cavity is provided on the peripheral side of the connecting end, and the block 323 is movably connected to the through hole 324. By way of example, the elastic member in this embodiment is a spring 322.

[0049] like Figure 5 As shown, when installing the bottle cap height measuring head, press the block 323 so that the block 323 is embedded in the embedding groove 321 as a whole, and at the same time squeeze the spring 322 so that the spring 322 is in a compressed state, and insert the connecting rod 32 into the connecting end of the body until the position of the block 323 and the through hole 324 remain corresponding. Under the action of the spring 322, the block 323 partially extends into the through hole 324, thereby realizing the connection between the connecting rod 32 and the connecting end, which has a simple structure and is easy to operate.
