DETAILED DESCRIPTION
[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0027] like Figures 1-7 As shown, this utility model provides an intermediate relay that is easy to assemble and disassemble, including a relay body 1, a slot 2 formed on the back of the relay body 1, and a fixing buckle 3 fixedly set on the top surface of the slot 2. It also includes: a first movable slot 5 formed on the bottom surface of the slot 2, and a second movable slot 6 connected to the bottom surface of the first movable slot 5; a telescopic buckle 7 movably inserted in the first movable slot 5, and a movable plate 8 inserted in the second movable slot 6, with a spring 9 abutting between the telescopic buckle 7 and the movable plate 8; a pull rod 10 fixedly set at the bottom of the telescopic buckle 7, and extending through the movable plate 8 and the bottom of the second movable slot 6 to the outside of the relay body 1; and an adjusting member 11 set on the movable plate 8 for adjusting the distance between the movable plate 8 and the bottom surface of the second movable slot 6 outside the relay body 1.
[0028] During installation, first tilt the relay body 1 upwards to lock the fixing clip 3 onto the top flange of the slide rail 14. Then, pull down the pull rod 10, causing the telescopic clip 7 to retract into the first movable groove 5. At this time, the spring 9 is compressed by the telescopic clip 7 and contracts. While maintaining the pulling force applied to the pull rod 10, tilt the relay body 1 downwards until the front of the slide rail 14 is completely in contact with the slot 2. Then, release the pull rod 10, and the spring 9 extends and returns to its original position, pushing the telescopic clip 7 out of the first movable groove 5 and locking it onto the bottom flange of the slide rail 14, cooperating with the fixing clip 3 to achieve the initial positioning of the relay body 1 on the slide rail 14. Finally, by adjusting the adjusting piece 11, the distance between the movable plate 8 and the bottom surface of the second movable groove 6 is increased, thereby further compressing the spring 9, increasing the pushing force applied by the spring 9 to the telescopic clip 7, and thus increasing the clamping force applied by the fixing clip 3 and the telescopic clip 7 to the slide rail 14, preventing the relay body 1 from easily sliding relative to the slide rail 14. For disassembly, simply reverse the above steps.
[0029] In one embodiment, flanges 12 are provided on both sides of the top of the first movable groove 5, and a baffle 13 for abutting against the bottom surface of the flanges 12 is fixedly provided at the bottom of the telescopic buckle 7.
[0030] With this design, the baffle 13 cannot slide out of the first movable groove 5 due to the blocking effect of the flange 12, thereby preventing the telescopic buckle 7 from being pushed out of the first movable groove 5 under the action of the spring force of the spring 9.
[0031] In an embodiment, the telescopic buckle 7 comprises a transverse abutting part 71 for abutting against the bottom surface of the slide rail 14 and a vertical telescopic part 72 inserted into the first movable slot 5, and the telescopic buckle 7 is in an overall L shape and has the same structure as the fixed buckle 3.
[0032] In this way, the contact area of the fixed buckle 3 and the telescopic buckle 7 with the slide rail 14 is increased, the stability of abutting is strengthened, and the difficulty of relative sliding of the relay main body 1 on the slide rail 14 is increased.
[0033] In an embodiment, the top of the first movable slot 5 is provided with a containing slot 15 for containing the transverse abutting part 71.
[0034] In this way, in the process of pulling down the pull rod 10 and driving the telescopic buckle 7 to retract into the first movable slot 5, the transverse abutting part 71 can be completely retracted into the containing slot 15, so as to ensure the flatness of the bottom surface of the clamping slot 2 and avoid interference with the process of clamping the slide rail 14 into the clamping slot 2.
[0035] In an embodiment, the adjusting member 11 comprises a screw rod 111 rotatably arranged at one end of the bottom of the movable plate 8 and extending to the outside of the relay main body 1 through the bottom of the second movable slot 6, and a screw handle 112 fixedly arranged at one end of the screw rod 111 extending out of the relay main body 1, and the screw rod 111 is threadedly connected with the relay main body 1.
[0036] In this way, the operator can easily rotate the screw rod 111 through the screw handle 112, so as to change the length of the screw rod 111 extending into the second movable slot 6. When the length of the screw rod 111 extending into the second movable slot 6 is increased, the movable plate 8 is pushed away from the bottom surface of the second movable slot 6 by the screw rod 111, so as to increase the distance between the movable plate 8 and the bottom surface of the second movable slot 6. When the length of the screw rod 111 extending into the second movable slot 6 is reduced, the movable plate 8 is pushed close to the bottom surface of the second movable slot 6 by the spring 9 under the pushing force of the spring 9 in the process of elongation and reset, so as to reduce the distance between the movable plate 8 and the bottom surface of the second movable slot 6.
[0037] In an embodiment, the bottom surface of the baffle 13 is fixedly provided with a first positioning column 16, the top surface of the movable plate 8 is fixedly provided with a second positioning column 17 corresponding to the first positioning column 16, and the spring 9 is sleeved between a set of corresponding first positioning columns 16 and second positioning columns 17.
[0038] In this way, the first positioning column 16 and the second positioning column 17 position both ends of the spring 9 and guide the telescopic deformation process of the spring 9, so as to prevent the spring 9 from tilting or deviating under stress and ensure the stability of the spring 9 in operation.
[0039] In an embodiment, the top surface of the transverse abutting part 71 is fixedly provided with the anti-skid rubber 4.
[0040] In this way, the static friction coefficient between the fixing buckle 3 and the telescopic buckle 7 and the slide rail 14 is increased, and the possibility of relative sliding of the relay main body 1 on the slide rail 14 is further reduced.
[0041] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and range of the equivalent elements of the claims are intended to be included in the present application.
[0042] It should be noted that if the present application embodiments involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain posture, and if the certain posture changes, the directional indications also change accordingly.
