Further, the pin includes a pin head section, a load-bearing section, a guide rail section and a locking key section, the spring and the positioning slider are sleeved on the guide rail section, the positioning slider is located behind the spring, and the diameter of the bearing section is It is larger than the pin head section and the guide rail section, and steps are respectively formed between the pin head section and the guide rail section.

Further, the lock key segment is provided with a snap ring, and the snap ring and the load-bearing segment jointly restrict the detachment of the positioning slider and the spring from the guide rail segment.

Further, the positioning slider includes a sliding sleeve, a connecting plate is arranged above the sliding sleeve, and the connecting hole is arranged on the connecting plate.

Further, the side wall of the beam is provided with a long hole, and bolts are arranged in the long hole to connect the connecting plate.

Further, an insulating layer is provided on the surface of the spring.

The quick-installed detachable pin with the above-mentioned structure has the following advantages:

When the utility model is fixed in the installation groove of the crossbeam, the fixing of the detachable pin is completed by fixing the positioning slide block on the side wall of the crossbeam through bolts, and the operation is very convenient.

When the utility model is disassembled from the crossbeam, only the bolts at the positioning slide block can be disassembled to withdraw from the installation groove, and the operation is also very convenient.

The surface of the spring of the utility model is provided with an insulating layer, which can prevent the generation of static electricity and avoid electric corrosion to the beam.

Detailed ways

In order to further explain the technical means and effects of the utility model to achieve the intended technical purpose, the structure, features and effects of the utility model will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

The structure of the beam 6 and column 7 assembled using the utility model is shown in Figure 5, Figure 6, Figure 7, and Figure 8. The inner wall of the beam 6 is symmetrically provided with a C-shaped installation groove 6-1, and the wall of the column 7 is provided with There are mounting holes, which can be used for the pin 1 to be inserted.

The quick-fit detachable pin described in this embodiment has a structure as shown in Fig. 1 and Fig. 2, and specifically includes a pin post 1, and a push spring 2 and a positioning slider 3 are sheathed on the pin post 1, and the positioning slider 3 There is a connection hole on the top, after the detachable pin is installed in the installation groove 6-1 of the beam 6, the positioning slider 3 extends out of the connection hole from the C-shaped mouth of the installation groove 6-1, and the positioning slider 3 is fixed on the Promptly complete the fixing of detachable pin on the side wall of crossbeam 6.

As shown in Figure 2 and Figure 3, the pin 1 includes a pin head section 1-1, a load-bearing section 1-2, a guide rail section 1-3 and a locking key section 1-4, and the spring 2 and the positioning slider 3 are worn on the On the guide rail section 1-3, the positioning slider 3 is located behind the spring 2, and the bearing section 1-2 has a diameter larger than that of the pin head section 1-1 and the guide rail section 1-3, and is the same as the pin head section 1-1 and the guide rail section 1-3 Steps are formed between them.

When the pin 1 is inserted into the mounting hole of the column 7, it can only be inserted to an appropriate length due to the restriction of the steps, and the spring 2 can be compressed to form a pre-tightening force, so that the assembly of the beam 6 and the column 7 is more stable without any loose.
