Description

Technical Field

[0001] The utility model relates to the field of electrical information, in particular to a pipeline connection protection device for electricity and its automation. Background Technique

[0002] In the field of electricity and its automation, the pipeline connection protection device is an important component. Its design and research and development need to fully consider the characteristics and requirements of the electrical system to ensure the stable and safe operation of the electrical system.

[0003] During the process of pipeline connection, inserting the pipeline into the box is an important step. Specifically, it refers to inserting one end of the wire protection pipe into the junction box (also called the bottom box or concealed box) to ensure that the wires are properly protected and fixed inside the wall or under the ground. During the process of inserting the PVC pipeline into the box, it is required to be straight and not inserted obliquely. When the pipeline sleeve is adhered, the adhesive must be applied to the entire pipe wall and the end to ensure firm adhesion.

[0004] At present, during the process of connecting and fixing the PVC pipeline, although applying more adhesive can ensure the adhesion effect, in actual use, since the PVC pipe needs to be slowly pushed into the sleeve from one end of the sleeve during the process of the PVC pipe entering the sleeve, it is possible that the adhesive originally applied on the pipe wall is extruded during the process of the PVC pipe entering the sleeve, resulting in a poor fitting effect between the outer wall of the PVC pipe and the inner wall of the sleeve. Therefore, a pipeline connection protection device for electricity and its automation is proposed to solve the above problems. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a pipeline connection protection device for electricity and its automation, aiming to improve the problem that the PVC pipe may push the adhesive during the process of entering the sleeve in the prior art, resulting in a poor adhesion effect between the PVC pipe and the sleeve.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figure 1 . Figure 3 AndFigure 4 , an embodiment provided by the present utility model: a pipeline connection protection device for electricity and its automation, including a sleeve 1 and a PVC pipe 2. The outer wall of the PVC pipe 2 contacts the inner wall of the sleeve 1. The diameters of the upper and lower ends of the inner wall of the sleeve 1 fit the outer wall of the PVC pipe 2. A connection mechanism 3 is arranged inside the sleeve 1. The connection mechanism 3 includes a contact block 31. The shape of the contact block 31 is formed by connecting a cuboid and an arc. The inner diameter of the arc-shaped part of the contact block 31 fits the outer diameter of the PVC pipe 2. Through the shape setting of the contact block 31, it is ensured that after the contact block 31 contacts the PVC pipe 2, it can maintain a good fitting state. The outer wall of the contact block 31 is slidably connected to the inner wall of the sleeve 1. A storage bin 32 is opened inside the contact block 31, and an adhesive is filled in the storage bin 32.

[0033] Refer to Figure 2 - Figure 4 , a liquid outlet hole 33 is opened at one end of the contact block 31 close to the middle of the sleeve 1. A baffle 34 is fixedly connected to the inner wall of the liquid outlet hole 33. The baffle 34 is circular, and multiple cutouts are arranged in the middle of the baffle 34. The baffle 34 has the property of shape memory. The baffle 34 remains circular in the state without external force, and the cutouts are in a blocked state. Through the shape and property setting of the baffle 34, it is ensured that the adhesive is not easily in contact with the outside, so as to ensure that the adhesive is not easily dried and loses its viscosity. A turntable 35 is rotatably connected to the inner wall of the sleeve 1 outside the contact block 31. A chute 36 is opened in the inner wall of the turntable 35. The shape of the chute 36 is arc-shaped. Control blocks 37 are slidably connected to the inner walls of the sleeve 1 above and below the turntable 35. One end of the control block 37 close to the turntable 35 is fixedly connected to a control rod 38. The diameter of the control rod 38 fits the width of the chute 36. The control rod 38 is arranged inside the chute 36. Through the setting of the diameter of the control rod 38 and the width of the chute 36, it is ensured that the position of the control rod 38 can be changed after the chute 36 rotates. A pull bar 39 is fixedly connected to the outer wall of the turntable 35. A straight groove with a width fitting the width of the pull bar 39 is opened on the outer wall of the sleeve 1. One end of the control block 37 close to the middle of the sleeve 1 is fixedly connected to a push plate 310. The outer wall of the push plate 310 fits the inner wall of the storage bin 32. The outer wall of the push plate 310 is piston-connected to the inner wall of the storage bin 32.

[0034] Refer to Figure 3 - Figure 5, inside the sleeve 1, inside the contact block 31 and at one end of the push plate 310 close to the middle of the sleeve 1, a limiting component 4 is jointly provided. The limiting component 4 includes a sliding groove 41. The sliding groove 41 is opened on the inner wall of the contact block 31. A clamping block 42 is slidably connected to the inner wall of the sliding groove 41. The shape of the clamping block 42 is a cuboid. A control piece 43 is fixedly connected to the outer wall of the clamping block 42. The outer wall of the control piece 43 fits against the inner wall of the sliding groove 41. One end of the control piece 43 close to the push plate 310 is elastically connected to the inner wall of the sliding groove 41 through a spring 44. One end of the spring 44 is fixedly connected to one end of the control piece 43 close to the push plate 310, and the other end of the spring 44 is fixedly connected to the inner wall of the sliding groove 41. A triangular groove 45 is opened at one end of the clamping block 42 away from the middle of the sleeve 1. A triangular block 46 is fixedly connected to one end of the push plate 310 close to the middle of the sleeve 1. The shapes of the triangular groove 45 and the triangular block 46 are fitted. A clamping groove 47 is opened on the inner wall of the sleeve 1. The shape and size of the clamping groove 47 are fitted with the shape and size of the clamping block 42.

[0035] Working principle: When in use, the staff first inserts the PVC pipe 2 into the inside of the sleeve 1. When the PVC pipe 2 is moved to a suitable position, the staff moves the pull bar 39, so that the pull bar 39 drives the turntable 35 to rotate. Thus, during the rotation of the turntable 35 by the chute 36, the distance from the area at the same horizontal position as the control rod 38 to the midpoint of the sleeve 1 is closer. Therefore, the control rod 38 moves towards the middle of the sleeve 1 under the drive of the turntable 35 and the chute 36.

[0036] When the control rod 38 moves towards the middle of the sleeve 1, the control rod 38 drives the control block 37 to move towards the middle of the sleeve 1. At this time, since the clamping block 42 is inside the clamping groove 47, the contact block 31 cannot move relative to the sleeve 1. Therefore, at this time, the control block 37 pushes the push plate 310 to move towards the middle of the sleeve 1, so that the push plate 310 pushes out the adhesive inside the storage bin 32.

[0037] During the process of the adhesive being pushed out, the push plate 310 drives the triangular block 46 to move towards the triangular groove 45. After the inclined surface of the triangular block 46 contacts the inclined surface of the triangular groove 45, at this time, the clamping block 42 moves away from the clamping groove 47 due to the inclined surface of the triangular groove 45 being squeezed, so that the clamping block 42 leaves the clamping groove 47.

[0038] After the clamping block 42 leaves the clamping groove 47, the contact block 31 and the sleeve 1 can slide relative to each other at this time. Therefore, when the control rod 38 continues to drive the control block 37 to move towards the middle of the sleeve 1, the contact block 31 moves towards the middle of the sleeve 1 along with the control block 37, so that the contact block 31 with the adhesive attached to its surface fits against the surface of the PVC pipe 2. At this time, the staff manually fixes the pull bar 39 for an appropriate period of time, and then releases it after the contact block 31 and the surface of the PVC pipe 2 are well fixed. At this time, the PVC pipe 2 can be well fixed to the inner wall of the sleeve 1, so as to achieve a better effect of the wire pipe entering the box and ensure that the pipeline can be well protected.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
