Description

TECHNICAL FIELD

[0001] The utility model relates to track safety equipment technical field, especially a kind of connecting structure of brake rail and slide. BACKGROUND

[0002] The existing Chinese utility model patent with publication number CN215720127U and the name of a kind of brake rail bolt anti-loosening device, the device includes anti-loosening plate, hex head bolt with hole, anti-rotation nut, spring washer and split pin;Among them, the anti-loosening plate includes anti-loosening bottom plate and anti-rotation plate;Anti-loosening bottom plate is longitudinally distributed;The front and rear ends of anti-loosening bottom plate are respectively provided with one anti-loosening head;Two anti-loosening heads are symmetrically distributed front and rear;The top of each anti-loosening head is respectively provided with one anti-rotation plate;Among them, the central position of anti-rotation plate is provided with anti-rotation tooth through-hole;The periphery of anti-rotation tooth through-hole has a plurality of anti-rotation tooth grooves;The position of each anti-loosening head directly below anti-rotation tooth through-hole is provided with anti-loosening head through-hole;Among them, anti-rotation tooth through-hole is used to be sleeved on the hex head bolt with hole screw cap hexagonal outer side;The anti-loosening head through-hole on anti-loosening head is used to place the middle upper part of spring washer;Among them, the bottom of split pin is in contact with the top surface of anti-rotation plate.When brake rail bolt (i.e. hex head bolt with hole) is about to loosen under external force, anti-rotation nut is blocked on the anti-rotation table of brake clamp and cannot rotate, only hex head bolt with hole rotates, the rotation of hex head bolt with hole screw cap will rotate with anti-rotation plate, when the anti-rotation shaft on anti-rotation plate rotates to one side of long round hole (i.e. second anti-rotation shaft mounting through-hole) on anti-loosening bottom plate, it cannot rotate any more, thereby limiting the rotation of screw cap of hex head bolt with hole, and further limiting the rotation of entire hex head bolt with hole, finally achieving the effect and result of preventing hex head bolt with hole from loosening. However, the structure of anti-loosening plate is too complex, not only the cost is high, but also the on-site installation is relatively cumbersome. CONTENT OF UTILITY MODEL

[0003] The utility model aims at the deficiency of prior art, provide a kind of connecting structure of brake rail and slide, which is simple in structure, low in cost and convenient to install on site.

[0004] To achieve the above object, the technical scheme of the connecting structure of brake rail and slide of the utility model is as follows:

[0005] A kind of connecting structure of brake rail and slide, including brake rail, slide and a plurality of bolts and nuts, bolt and nut are connected as a whole by thread connection brake rail and slide, the brake rail can be detachably connected with a limiting member, for limiting the movement of bolt away from the direction of nut.Brake rail and slide are connected, and then the limiting member is installed on the brake rail.

[0006] Preferably, the limiting member includes a baffle, and the baffle is provided with a support leg on both sides for connecting the brake rail.

[0007] Preferably, the baffle is provided between the end face of the bolt head and the rubber pad.

[0008] Preferably, the spring washer and the flat washer are sequentially sleeved on the side of the bolt next to the head. The spring washer can also prevent the bolt from loosening.

[0009] Preferably, the nut is a rotation-preventing nut, and the sliding seat is provided with a limiting surface matched with the rotation-preventing nut. The outer surface of the rotation-preventing nut is attached to the limiting surface, and when the bolt is turned, the nut does not need to be additionally limited by a wrench or other tools, and the operation is more convenient.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] Only the limiting member can limit the movement of the bolt away from the nut, limit the relative movement between the bolt and the nut, that is, can play a loosening-preventing role, ensure the firm and reliable connection between the brake rail and the sliding seat, simple structure, low cost, and more convenient on-site installation. BRIEF DESCRIPTION OF DRAWINGS

[0012] Figure 1 is the three-dimensional view of the connecting structure of the brake rail and the sliding seat of the utility model.

[0013] Figure 2 is the side view of the connecting structure of the brake rail and the sliding seat of the utility model.

[0014] Figure 3 is Figure 2 A-A sectional view.

[0015] Figure 4 is Figure 3 the enlarged view of C.

[0016] Among them, 1 brake rail, 2 sliding seat, 21 limiting surface, 3 bolt, 4 nut, 5 spring washer, 6 flat washer, 7 limiting member, 71 baffle, 72 supporting leg, 8 rubber pad. DETAILED DESCRIPTION

[0017] The utility model will be further illustrated below in combination with the drawings and specific embodiments, and it should be understood that these embodiments are only used to illustrate the utility model and not used to limit the scope of the utility model, and after reading the utility model, the modification of various equivalent forms of the utility model by those skilled in the art falls within the scope defined by the claims attached to the present application.

[0018] As Figures 1-4As shown, a brake rail and slide connection structure, comprising brake rail 1, slide 2 and several bolts 3 and nuts 4, the bolt next to the head side in turn with spring washer 5 and flat washer 6, spring washer on the bolt can also play a anti-looseness effect, nut for anti-rotation nut, slide set with anti-rotation nut limit surface 21, the outer side of the anti-rotation nut and the limit surface, when the bolt is turned, no additional use wrench or other tools to limit the nut with the rotation, more convenient operation, bolt and nut thread connection will brake rail and slide connection as a whole, brake rail can be disassembled and connected to the limiting piece 7, used to limit the bolt movement away from the nut, limiting piece includes baffle 71, baffle both sides of the bending out of the foot 72, both sides of the foot through the screw and brake rail fixedly connected, to ensure the resistance of the baffle, baffle and bolt head between the end face is provided with rubber pad 8, rubber pad is bonded to the inner wall of the baffle, considering the manufacturing error, baffle is difficult to directly adhere to the bolt head in the assembly process, therefore, the use of rubber pad to fill the gap between the baffle and the bolt head, so that the baffle can be pressed on the bolt head, so as to reduce the manufacturing difficulty of the limiting piece, at the same time, the rubber pad can also hinder the rotation of the bolt.

[0019] A brake rail and slide connection structure of the specific working process and principle: after the outer wall of the anti-rotation nut and the limiting surface are adhered, the bolt with spring washer and flat washer is inserted through the through hole of the brake rail, and then is threadedly connected with the anti-rotation nut. At this time, only the bolt needs to be twisted. After the brake rail and the slide are fixedly connected, the limiting piece is covered on the top of the bolt, and the limiting piece is fixed on the brake rail through the screw. If the bolt is loose, the bolt will only move upwards of the brake rail. At this time, the limiting piece presses the bolt, and the bolt has no moving space, so the loosening phenomenon will not occur, thereby ensuring that the brake rail and the slide are firmly and reliably connected. Compared with the prior art structure, the structure is simpler, the cost is lower, and the assembly and disassembly are more convenient.
