Detailed description of the invention
For further setting forth the utility model for the technological means that reaches predetermined technique object and take and effect, below in conjunction with accompanying drawing and preferred embodiment, structure of the present utility model, feature and effect are described in detail as follows.
Use the utility model to carry out the structure of the crossbeam 3 and column 4 assembled as shown in Fig. 3, Fig. 6, Fig. 7, Fig. 8, crossbeam 3 inwall is symmetrically arranged with C type mounting groove 3-1, the wall of column 4 is provided with installing hole, this installing hole can insert for pin 1.
embodiment 1
The removable pin of fast-assembling described in the present embodiment, structure is as Fig. 1, Fig. 2, Fig. 4, shown in Fig. 5, specifically comprise pin 1, the goring push spring 2 be connected with pin 1, spring 2 tail end is provided with calabash shape or U-shaped clamping ear 2-2, clamping ear 2-2 is bent to form by spring steel wire, clamping ear 2-2 protruding spring 2 periphery, the width of clamping ear 2-2 is greater than crossbeam 3 mounting groove C type mouth width, with mounting groove C type interruption-forming tight fit, the wall of crossbeam 3 mounting groove arranges one-sided breach 3-2, as Fig. 6, shown in Fig. 7, clamping ear 2-2 ejects at mounting groove breach 3-2 place and namely completes the fixing of removable pin.Here ejection refers to that clamping ear 2-2 ejects from mounting groove C type mouth and springs into breach 3-2 part spring steel wire under the effect of self-recovery power, thus is stuck in breach 3-2 place.
One-sided breach 3-2 set on the wall of crossbeam 3 mounting groove, can use the milling cutter processing of small-sized location.
As shown in Figure 4, Figure 5, pin 1 comprises plunger section 1-1, load section 1-2 and connector 1-3, is greater than plunger section 1-1, between two sections, forms step by connector 1-3 linking springs 2, load section 1-2 diameter.When in the installing hole that pin 1 inserts column 4, by the restriction of step, can only suitable length be inserted, and can holddown spring 2, form pretightning force, make crossbeam 3 more firm with the assembling of column 4, can not produce loosening.
As shown in Figure 4, Figure 5, spring 2 and pin 1 link diameter diminish, with the connector 1-3 clamping of pin 1.
As shown in Fig. 2, Fig. 5, U-shaped clamping ear 2-2 comprises the section of stretching out 2-2-1, load section 2-2-2, introduction segment 2-2-3 and rear 2-2-4, and introduction segment 2-2-3 and rear 2-2-4 forms hyperbolic waveform.Introduction segment 2-2-3 is a depressed part, adapts to the C type mouth cambered surface of mounting groove 3-1, facilitates removable pin to push mounting groove 3-1, with rear 2-2-4 acting in conjunction, can effectively prevent clamping ear 2-2 in progradation from ejecting from C type mouth.
The section of stretching out 2-2-1 is straightway, and load section 2-2-2 is segmental arc.The section of stretching out 2-2-1 and load section 2-2-2 can form suitable elastic force, makes clamping ear 2-2 and mounting groove C type interruption-forming resilient engagement.
After crossbeam 3 and column 4 are assembled, if adopt Conventional springs, spring can often slide in mounting groove 3-1; also result in the generation of electrostatic thus; spring 2 surface in the present embodiment is provided with insulating layer, can effectively prevent electrostatic from producing, and avoids causing galvano-cautery to crossbeam.
When removable pin described by the present embodiment is dismantled from crossbeam 3, the instruments such as screwdriver can be used to compress the introduction segment 2-2-3 of clamping ear 2-2, by clamping ear 2-2 reduced width, make clamping ear 2-2 can reenter mounting groove C type mouth, namely removable pin can be exited from mounting groove 3-1, very convenient.
embodiment 2
As shown in Figure 9, Figure 10, calabash shape clamping ear 2-2 also comprises the section of stretching out 2-2-1, load section 2-2-2, introduction segment 2-2-3 and rear 2-2-4, and introduction segment 2-2-3 and rear 2-2-4 forms hyperbolic waveform.Introduction segment 2-2-3 is a depressed part, adapts to the C type mouth cambered surface of mounting groove 3-1, facilitates removable pin to push mounting groove 3-1, with rear 2-2-4 acting in conjunction, can effectively prevent clamping ear 2-2 in progradation from ejecting from C type mouth.
Load section 2-2-2 is segmental arc, the Breadth Maximum of load section 2-2-2 is greater than the spacing between the section of stretching out 2-2-1 and introduction segment 2-2-3, the section of stretching out 2-2-1 and load section 2-2-2 can form suitable elastic force, makes clamping ear 2-2 and mounting groove C type interruption-forming resilient engagement.
Described just in order to the utility model is described above, be construed as the utility model and be not limited to above embodiment, meet the various variants of the utility model thought all within protection domain of the present utility model.
