[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1-3 As shown, a quick-fixed insulator iron cap provided by an embodiment of the utility model comprises an insulator body 1, the insulator body 1 comprises an iron cap body 2, a porcelain piece 5 is fixed to the bottom of the iron cap body 2, a connecting rod 3 is fixed to the bottom of the porcelain piece 5, a cone 20 is integrally formed at the bottom end of the connecting rod 3, an installation cavity 4 is arranged inside the iron cap body 2, a slide rod 10 is fixed to the inside of the iron cap body 2, two sliders 9 are slidably connected to the outside of the slide rod 10, a clamping plate 12 is integrally formed on the top outer wall of the two sliders 9, a clamping tooth 13 is integrally formed on the top of the clamping plate 12, a spring 11 is sleeved on the outside of the slide rod 10, the spring 11 is located between the iron cap body 2 and the slider 9, and a plug-in hole 22 connected to the installation cavity 4 is arranged on the top of the iron cap body 2.

[0021] Specifically, in this embodiment, an insulator body 1 is included, and the insulator body 1 includes an iron cap body 2. A porcelain piece 5 is fixed to the bottom of the iron cap body 2. The porcelain piece 5 is made of ceramic material. A connecting rod 3 is fixed to the bottom of the porcelain piece 5. A cone 20 is integrally formed at the bottom end of the connecting rod 3. The cone 20 is an inverted cone. An installation cavity 4 is provided inside the iron cap body 2. A slide rod 10 is fixed inside the iron cap body 2. Two sliders 9 are slidably connected to the outside of the slide rod 10. A card plate 12 is integrally formed on the top outer wall of the two sliders 9. The two card plates 12 are symmetrical about the center line of the iron cap body 2. The top of the card plate 12 A latch tooth 13 is integrally formed, and a spring 11 is sleeved on the outside of the slide rod 10. The spring 11 is located between the iron cap body 2 and the slider 9. The spring 11 is used to apply elastic force to the slider 9 so that the two sliders 9 tend to approach each other. A plug-in hole 22 connected to the mounting cavity 4 is provided on the top of the iron cap body 2. When the two insulators need to be connected and fixed, the connecting rod 3 of one insulator is inserted into the plug-in hole 22 of the other insulator and pressed hard, so that the two insulators can be quickly fixedly connected. When multiple insulators are connected end to end for use, the assembly efficiency of the insulators is improved.

[0022] The utility model provides a quickly fixed insulator iron cap, which is provided with a spring 11, a cone 20 and a clamping plate 12. The spring 11 applies elastic force to the clamping plate 12, so that after the connecting rod 3 is inserted into the plug hole 22, the clamping teeth 13 of the clamping plate 12 can quickly block the cone 20, thereby achieving the effect that multiple insulators can be quickly fixed when connected, and improving the assembly efficiency of the insulators.

[0023] In another embodiment provided by the utility model, a connector 6 is integrally formed on the top outer wall of the porcelain part 5, which is a structure with an expanded top. A concave surface 7 is provided on the outer wall of the connector 6. An adhesive 8 is filled between the connector 6 and the iron cap body 2. The adhesive 8 is filled between the connector 6 and the iron cap body 2 to achieve the effect of fixing the connector 6 and the iron cap body 2. At the same time, the design of the concave surface 7 can increase the filling amount of the adhesive 8, so that the connector 6 and the iron cap body 2 are fixed more firmly; a sealing plug 16 is fixed inside the installation cavity 4, and the sealing plug 16 is located at the top of the connector 6. The sealing plug 16 divides the installation cavity 4 into two spaces, upper and lower, so that the adhesive 8 cannot enter the installation cavity 4 at the top of the sealing plug 16; a bevel 17 is provided on the top outer wall of the latch tooth 13, and the bevel 17 is adapted to the cone 20. The bevel 17 plays a guiding role, so that the latch tooth 13 and the cone 20 are connected faster and more smoothly. A buckle tooth 18 is integrally formed at the bottom of the latch tooth 13, and a buckle tooth 18 is provided on the top outer wall of the cone 20. The buckle groove 19 matched with the buckle tooth 18 is an annular structure. By setting the buckle tooth 18 and the buckle groove 19, the buckle tooth 18 on the clamping tooth 13 is matched with the buckle groove 19 of the cone 20, so that the two insulators are more firmly connected when connected, thereby making the assembly of the insulator more reliable; a guide column 14 is fixed to the outer wall of one side of the clamping plate 12, and one end of the guide column 14 extends to the outside of the iron cap body 2 and is hinged with a pull ring 15, and the guide column 14 can provide guidance for the movement of the clamping plate 12 The action of the clamping plate 12 makes the movement of the clamping plate 12 more stable. The clamping plate 12 can be pulled by the pull ring 15, thereby separating the latching tooth 13 from the cone 20, so that the two insulators can be disassembled after assembly; the top inner wall of the installation cavity 4 is provided with a blocking surface 21, which is adapted to the latching tooth 13. The blocking surface 21 can form a blocking latching tooth 13, so that the blocking surface 21 can provide support for the latching tooth 13, so that the latching tooth 13 can withstand the force of the cone 20.

[0024] Working principle: when it is necessary to connect and fix two insulator bodies 1, the connecting rod 3 of one insulator is inserted into the insertion hole 22 of the other insulator, and then the two insulators are squeezed so that the cone 20 is located at the bottom of the latch 13. At this time, the spring 11 applies elastic force to the slider 9, and the latch 13 blocks the cone 20, so that the connecting rod 3 of one insulator can be fixed inside the iron cap body 2 of the other insulator; when it is necessary to disassemble the two insulators, firstly, the two insulators are squeezed against each other so that the buckle teeth 18 are disengaged from the buckle grooves 19, and then the two pull rings 15 are pulled away from the iron cap body 2 so that the latch 13 does not block the cone 20, and the two insulators can be separated at this time.

[0025] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
