Description

Technical Field

[0001] The utility model relates to a length measuring tool, in particular to a metal carrier inner core length measuring tool, belonging to the technical field of length measurement. Background Art

[0002] The inner core of the metal carrier is not integrated inside the carrier, but is divided into sections of different lengths according to the needs of the production task. This will result in a wide variety of carriers, and it is difficult to distinguish the internal length by appearance, so as to classify and distinguish them. Once a production error occurs, the products will be mixed together. The pores in the inner core of the metal carrier are very narrow, about 1.3mm;

[0003] The existing technology for distinguishing is to use a small metal stick to penetrate into the hole until it encounters an obstacle, and then use a ruler to measure the length of the measuring rod that penetrates into the carrier after encountering the obstacle. Each end needs to be measured once, and then the length of the blank part in the middle is subtracted. In this way, the length of the metal carrier core can be obtained. Another reason is that the length of the blank area inside the carrier is not a fixed value. Sometimes, the measurement by this method still cannot get an accurate value. It brings difficulties to the distinction work, and it is impossible to quickly obtain the length of the metal carrier core.

[0004] Therefore, there is an urgent need to improve the existing metal carrier core length measurement tools to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide a tool for measuring the length of the inner core of a metal carrier, which can solve the problems raised in the background technology.

[0006] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include: a metal carrier inner core length measuring tool, including a measuring rod, a measuring head is welded at the lower end of the measuring rod, a straightening component is arranged on the surface of the measuring rod, and the measuring head is in the shape of a water drop.

[0007] Preferably, the measuring head is made of tough metal wire, the surface of the measuring rod is provided with scale marks, and a handle is provided at one end of the measuring rod.

[0008] Preferably, the straightening assembly comprises a straightening groove, the straightening groove is arranged on the surface of the measuring rod, a mounting seat is arranged at the lower end of the straightening groove, and a supporting rod is movably mounted on the mounting seat.

[0009] Preferably, a groove is formed at one end of the supporting rod, and a pulley is detachably and rotatably mounted inside the groove.

[0010] Preferably, the surface of the straightening groove is movably sleeved on an adjustment ring seat, and movable support rods are movably mounted on both sides of the adjustment ring seat, and one end of the movable support rod is movably connected to the supporting rod.

[0011] Preferably, an activity groove is formed inside the measuring rod, a moving plate is movably installed inside the activity groove, and the moving plate is connected to the adjusting ring seat.

[0012] Preferably, a guide rod is movably inserted through the middle of the moving plate, both ends of the guide rod are fixedly connected to the inner wall of the activity groove, a support spring is sleeved on the surface of the guide rod, and the upper end of the support spring is fixedly connected to the moving plate.

[0013] Preferably, sliding grooves are formed on both sides of the straightening groove, the sliding grooves are connected to the activity groove, a slider penetrates through the inside of the sliding groove, and both ends of the slider are fixedly connected to the adjusting ring seat and the moving plate respectively.

[0014] The utility model at least has the following beneficial effects:

[0015] 1. In the utility model, the length of the inner core of the metal carrier is measured. The water-drop-shaped measuring head enters the narrow small hole of the inner core of the metal carrier, and the metal thin wire deforms and generates friction with the inner wall of the hole to form resistance. When the resistance disappears, that is, the measuring head has passed through the hole, read the scale value on the measuring rod, which is the corresponding length of the inner core of the metal carrier.

[0016] 2. In the utility model, when the measuring head and the measuring rod are inserted into the metal carrier, the support spring supports the moving plate, the moving plate supports the adjusting ring seat through the slider, and the adjusting ring seat supports the supporting rod through the movable support rod, so that the supporting rod unfolds. As the measuring rod is inserted, the supporting rod contacts the inner wall of the metal carrier, and the measuring rod can be kept in the middle of the metal carrier, which is convenient for the measuring rod and the measuring head to be inserted, and prevents the measuring head from contacting the inner wall of the metal carrier when it is not inserted into the inner core of the metal carrier, affecting the measurement.
