Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of railway turnout installation, and in particular relates to a high-strength buckled type insulating component. Background Art
[0002] During the installation of railway turnouts, the turnout square steel device needs to be insulated from the rails to maintain the operation of the track circuit.
[0003] Commonly used connection structures include T-irons or connectors with mounting holes. For connectors with mounting holes, insulating sheets are usually inserted from both ends of the mounting holes and then connected to the pull rods. The contact area between the split-insertion insulating sheets and the mounting holes is small, which is easy to wear during use, and the insulation level is also relatively low. Utility Model Content
[0004] The utility model provides a high-strength buckled insulating piece, which provides an insulating connection part for a pull rod by using a cover structure buckled up and down and an integral insulating structure formed by plugging, so as to solve the deficiencies mentioned in the prior art.
[0005] The technical solution adopted by the utility model is:
[0006] A high-strength buckle-type insulating component comprises an insulating upper cover and an insulating lower cover, which are buckled together to form an installation cavity, and the installation cavity is provided with an installation opening, an insulating protrusion I is provided on the inner wall of the insulating upper cover, and an insulating protrusion II is provided on the inner wall of the insulating lower cover, and the insulating protrusion II is inserted into the insulating protrusion I. The installation opening serves as a passage opening of the installation cavity for a pull rod to pass through, and the insulating protrusion I and the insulating protrusion II support the plug-in connection when the upper and lower covers are buckled together, so that the upper and lower insulating covers become a whole, and the pull rod is sleeved on the plugged insulating protrusion structure, which not only increases the creepage distance, but also increases the friction area, and can increase the overall thickness of the insulating tube wall and improve the strength.
[0007] As a preferred solution of the utility model, the contact end faces of the insulating protrusions I and II have a taper. The taper can ensure that the insulating protrusions I and II are in firmer contact and have a larger contact area. The overall thickness of the plugged insulating protrusions I and II is much greater than the thickness of the insulating sheet currently used, which effectively improves the force strength. Moreover, the contact area between the insulating protrusions I and II and the pull rod after plugging is larger. The setting of the taper can also play a waterproof role.
[0008] As a preferred solution of the utility model, the inner wall of the insertion hole of the insulating protrusion I is provided with a taper; the outer wall of the insulating protrusion II is provided with a taper.
[0009] As a preferred solution of the utility model, the outer wall of the insulating protrusion II is a structure that is small at the top and large at the bottom, and the inner wall of the insulating protrusion I matches it.
[0010] As a preferred solution of the utility model, the insulating upper cover includes an upper cover plate and an upper cover side plate, the upper cover side plates are vertically arranged on the three sides of the upper cover plate, the insulating protrusion I is arranged on the upper cover plate, and the protrusion direction of the insulating protrusion I is the same as the protrusion direction of the upper cover side plate; the upper cover side plate is buckled with the lower cover. The upper cover plate is arranged on the three sides of the upper cover plate, leaving a side without the upper cover side plate, which will form an installation opening of the installation cavity with the side of the lower cover plate without the lower cover side plate.
[0011] As a preferred solution of the utility model, the insulating lower cover includes a lower cover plate and a lower cover side plate, the lower cover side plates are vertically provided on the three sides of the lower cover plate, the insulating protrusion II is provided on the lower cover plate, and the protrusion direction of the insulating protrusion II is the same as the protrusion direction of the lower cover side plate; the lower cover side plate is buckled with the upper cover side plate and forms an installation cavity with the upper cover plate and the lower cover plate.
[0012] As a preferred solution of the utility model, a sinking part is provided on the inner side of the top of the upper cover side plate, and a sinking part is provided on the outer side of the top of the lower cover side plate. After the sinking part is provided, a step structure is formed, and the steps of the upper cover side plate and the lower cover side plate are in opposite directions and can be buckled together.
[0013] The utility model uses a snap-fitting upper and lower cover structure to replace the existing structure, and the insulating upper cover and the insulating lower cover are both insulating parts. The insulating protrusion structure inserted in the installation cavity serves as a structure connected to the pull rod, which not only increases the creepage distance, but also increases the friction area and the overall thickness of the insulating tube wall, and also improves the strength.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Example:
[0022] A high-strength buckle-type insulating member, such as Figure 1 As shown, it includes an insulating upper cover 1 and an insulating lower cover 2, both of which are made of insulating materials. The insulating upper cover 1 and the insulating lower cover 2 are buckled together to form a mounting cavity 3, and the mounting cavity 3 is provided with a mounting opening 4, an insulating protrusion I5 is provided on the inner wall of the insulating upper cover 1, and an insulating protrusion II6 is provided on the inner wall of the insulating lower cover 2, and the insulating protrusion II is inserted into the insulating protrusion I5.
[0023] Specifically, Figure 2 and 3 As shown, the insulating upper cover 1 includes an upper cover plate 100 and an upper cover side plate 101. The upper cover side plates 101 are vertically arranged on the three sides of the upper cover plate 100, leaving a side without an upper cover side plate. The insulating protrusion I5 is arranged on the upper cover plate 100, and the protrusion direction of the insulating protrusion I is the same as the protrusion direction of the upper cover side plate;
[0024] In addition, a sinking portion is provided on the inner side of the top of the upper cover side plate 101, and a step structure is formed after the sinking portion is provided.
[0025] like Figure 4 and 5 As shown, the insulating lower cover 2 comprises a lower cover plate 200 and a lower cover side plate 201. The lower cover side plates 201 are vertically arranged on the three sides of the lower cover plate 200, leaving a side without the lower cover plate. The insulating protrusion II is arranged on the lower cover plate 200, and the protrusion direction of the insulating protrusion II is the same as that of the lower cover side plate; a sinking part is arranged on the outer side of the top of the lower cover side plate 201. After the sinking part is arranged, a step structure is formed, and the steps of the upper cover side plate and the lower cover side plate are in opposite directions and can be buckled together.
[0026] The lower cover side plate 201 is buckled with the corresponding upper cover side plate 101 and forms an installation cavity with the upper cover plate and the lower cover plate. The side of the upper cover plate without the upper cover side plate and the side of the lower cover plate without the lower cover side plate form an installation opening of the installation cavity.
[0027] The installation opening serves as a channel opening of the installation cavity for the pull rod to pass through. The insulating protrusions I and II support the plug-in when the upper and lower covers are buckled together to make the insulating upper and lower covers a whole. The pull rod is sleeved on the plug-in insulating protrusion structure, which not only increases the creepage distance, but also increases the friction area, which can increase the overall thickness of the insulating tube wall and improve the strength.
[0028] Moreover, the contact end faces of the insulating protrusions I and II have a taper. In this embodiment, the inner wall of the jack of the insulating protrusion I is provided with a taper; the outer wall of the insulating protrusion II is provided with a taper, and the outer wall of the insulating protrusion II is a small upper and large lower structure, and the inner wall of the insulating protrusion I matches it. The taper can ensure that the insulating protrusions I and II are in firmer contact and have a larger contact area. The overall thickness of the plugged insulating protrusions I and II is much larger than the thickness of the existing insulating sheet, which effectively improves the force strength. Moreover, the contact area of the insulating protrusions I and II connected with the pull rod after plugging is larger. The setting of the taper can also play a waterproof role.
[0029] When in use, place the pull rod on the lower cover first and let the insulating protrusion II pass through the hole of the pull rod first, then buckle the upper cover onto the lower cover, insert the insulating protrusion II into the insulating protrusion I, and the outer wall of the insulating protrusion I will be partially inserted into the hole of the pull rod. After buckling, an integral insulating part connected to the pull rod is formed.
