Description
Technical Field
[0001] The utility model belongs to the technical field of rod cores, in particular to a combined rod core. Background Art
[0002] The rod core is a cylindrical component similar to a tubular structure, mainly composed of an inner core and an outer shell, wherein the inner core contains components such as an inductor coil and a capacitor, and the outer shell is a protective and supporting structure. The role of the rod core is similar to that of a cable that transmits current. It can transmit signals in the circuit to achieve a variety of functions. Today's rod cores are widely used in: electronic communications, computer networks, medical equipment and other fields, and have become an important part of modernization. There are many types of combined rod cores currently available on the market, but there are still some disadvantages;
[0003] For example, in actual use, a general combination rod core, which is used in combination with an inner core and an outer shell, may have an unstable combination, which may cause the inner core to loosen. At the same time, it is very inconvenient to disassemble the general combination rod core. Once a problem occurs with the inner core, it is difficult to disassemble and separate the inner core and the outer shell, which is not conducive to the inspection and maintenance of the inner core. In addition, the combination rod core will also be affected by external vibration and internal overheating, which will greatly reduce the service life of the combination rod core. Therefore, we propose a combination rod core to solve the above problems. Utility Model Content

The combined use of the inner core and the outer shell may lead to an unstable combination, which may cause the inner core to loosen. At the same time, it is very inconvenient to disassemble the combined rod core. Once the inner core has a problem, it is difficult to disassemble and separate the inner core and the outer shell, which is not conducive to the inspection and maintenance of the inner core. In addition, the combined rod core may also be affected by external vibration and internal overheating, which may greatly reduce the service life of the combined rod core.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a combined rod core, comprising: an upper shell, an inner core is arranged at the lower part of the upper shell; further comprising: a locking mechanism is arranged inside the upper shell and the lower shell, wherein the locking mechanism comprises an inner core, a spring, a connecting block, a pushing block and a moving ball block, a spring is arranged outside the right side of the inner core, and a connecting block is fixedly installed at the right end of the inner core, and the left side of the spring is fixedly connected to the right side of the upper shell and the lower shell, and the right side of the spring is fixedly connected to the left side of the connecting block;

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: the combined rod core is provided with a locking mechanism so that the inner core and the outer shell of the combined rod core are firmly locked together, thereby avoiding the inner core from loosening and causing damage to the inner core. At the same time, a detachable mechanism is provided so that the inner core and the outer shell of the combined rod core are easy to disassemble and separate, and the inner core is easy to inspect and repair. In addition, a heat dissipation and anti-vibration mechanism is provided so that the combined rod core can quickly dissipate heat, which will greatly extend its service life; an inner core, a spring, a connecting block and a pushing block are provided, and the inner core is installed inside the upper outer shell and the lower outer shell. A spring is provided on the outside of the right side of the inner core, and the right end of the inner core is fixedly connected to the connecting block.

When the connecting block is pushed manually, the connecting block will push the inner core and the pushing block to move to the left, and the spring outside the right side of the inner core will shrink. At this time, the pushing block and the moving ball block will separate from tightly fitting, and the moving ball block will move inward. At this time, the inner core and the upper outer shell and the lower outer shell will become loose. When the hand pushing the connecting block is released, the spring will rebound, that is, the inner core and the pushing block will move to the right and reset. At this time, the pushing block will be in close contact with the moving ball block, so that the moving ball block will move outward, that is, the inner core and the upper outer shell and the lower outer shell will be firmly locked, thereby avoiding the loosening of the inner core, which will cause damage to the inner core.
[0013] An upper shell, a lower shell, a fixing block and bolts are provided. The upper shell is provided above the inner core, and the lower shell is provided below the inner core. The upper shell and the lower shell are connected by snapping. At the same time, the fixing block is installed by symmetrical rotation of the upper shell in the front and back directions. The fixing block and the lower shell are firmly fixed by bolts, that is, the upper shell and the lower shell are wrapped around the outer side of the inner core. When the inner core is damaged, the bolts fixing the fixing block and the lower shell are first loosened, and the bolts are pulled out from the lower shell and the fixing block, that is, the upper shell and the lower shell can be separated from each other up and down, so that the inner core inside the upper shell and the lower shell can be inspected.
[0014] A lower rubber pad, an upper rubber pad, a heat dissipation hole and a filter are provided. A card slot is opened inside the lower rubber pad, and a card block is fixedly installed below the upper rubber pad, that is, the card block and the card slot can be firmly snapped together, and the lower rubber pad and the upper rubber pad are fixedly wrapped on the outside of the inner core, which can reduce the damage of the inner core caused by external vibration. At the same time, heat dissipation holes are opened inside the upper shell and the lower shell, and the heat dissipation holes can quickly dissipate the heat of the inner core, which will greatly extend its service life. In addition, a filter is provided inside the heat dissipation hole, and the filter can prevent dust from falling from the heat dissipation hole to the inner core. BRIEF DESCRIPTION OF THE DRAWINGS
