Description

Technical Field

[0001] The utility model relates to a fastener, in particular to an embedded connecting fastener, belonging to the technical field of connecting fasteners. Background Art

[0002] A power strip, also known as a power strip or socket strip, is a mobile power distribution device with multiple sockets, used to connect multiple power plugs to save space and wiring. Power strips are consumables for daily use. They are very commonly used in daily life and work. With the popularization of electronic products and the increasing demand for electricity, the power strip market is also expanding. In homes, power strips are used to provide additional power sockets to meet the connection needs of various household appliances. In offices and industrial environments, power strips also play an important role. They are used to connect multiple devices and provide necessary power distribution. They are indispensable electrical equipment for people.

[0003] Existing power strips are generally assembled and fixed with fasteners during production. Most of the existing ones use metal screws to assemble and fix the power strip's shell and base plate, thereby enclosing the internal electrical components. However, the existing metal screws are generally directly connected to the power strip's shell through threads. After long-term use, the threaded connection is prone to loosening, resulting in an unstable connection. To this end, we provide an embedded connection fastener to solve the above problem. Utility Model Content

[0004] In order to solve the above problems, the present invention provides an embedded connection fastener to solve the above problems. The specific technical solution is as follows:

[0005] An embedded connection fastener comprises a plug-in connector, a sleeve is provided on the outside of the plug-in connector, and a fixing member is provided on the lower part of the plug-in connector; the plug-in connector comprises an outer rod, the sleeve comprises a sleeve, and the outer surface of the outer rod is threadedly connected to the inner wall of the sleeve; the fixing member comprises a deformation block, the upper part of the deformation block is connected to a protrusion, and the protrusion protrudes horizontally toward the outside of the deformation block; the inner walls of the deformation block and the protrusion are squeezed against the outer surface of the sleeve; the fixing member also comprises an inner rod, the inner wall of the outer rod is provided with a fixing hole, and the outer surface of the inner rod is threadedly connected to the outer rod.

[0006] Preferably, the connector further comprises a first rotating block, the lower surface of the first rotating block is fixedly connected to the outer rod, and a cross slot is formed on the upper portion of the first rotating block.

[0007] Preferably, the kit further comprises a top plate, the inner side of the top plate is fixedly connected to the sleeve body, and the upper surface of the top plate is in contact with the first rotating block.

[0008] Preferably, the lower portion of the sleeve is provided with slots, and the number of the slots is three.

[0009] Preferably, the fixing member further includes a second rotating block, the upper surface of the second rotating block is fixedly connected to the deformation block, and a cross groove is formed on the upper portion of the second rotating block.

[0010] Preferably, the upper surface of the second rotating block is also fixedly connected to the inner rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The embedded connection fastener is provided with components such as a plug-in piece and a fixing piece. During installation, the inner rod is inserted into the inside of the fixing hole. Under the action of the thread, the protrusion moves upward close to the extrusion sleeve, so that when the lower part of the sleeve is inserted into the inside of the protrusion and the deformation block, under the action of the extrusion force, the sleeve shrinks toward the middle and the deformation block expands outward. When they squeeze each other, the sleeve shrinks inward, making the sleeve more tightly fixed to the outer rod to prevent shaking during subsequent use, thereby increasing the firmness of the plug-in piece and the kit, achieving the effect of increasing stability, thereby solving the problem that the existing metal screws are generally directly connected to the power strip shell through threads, and the threaded connection is prone to loosening, resulting in unstable connection.

[0013] 2. The embedded connection fastener is provided with components such as slots and protrusions. The slots prevent the lower part of the sleeve from forming a complete ring, so that it can move closer to the center after being squeezed. The protrusions can block the socket bottom plate to increase the fixing effect. When the deformation block expands and deforms, the contact area between it and the socket bottom plate is increased to increase the fixing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will now be further described with reference to the accompanying drawings.

[0020] See also Figures 1-4 , including a connector 1, a sleeve 2 is provided on the outside of the connector 1, a fixing member 3 is provided at the lower part of the connector 1, the connector 1 includes an outer rod 101, the sleeve 2 includes a sleeve 201, and the outer surface of the outer rod 101 is threadedly connected to the inner wall of the sleeve 201;

[0021] The connector 1 also includes a first rotating block 103, the lower surface of which is fixedly connected to the outer rod 101. A cross slot is provided on the upper portion of the first rotating block 103. By inserting a screwdriver into the cross slot, the first rotating block 103 can be rotated, thereby driving the outer rod 101 to rotate for easy use. This is existing technology and will not be described in detail here.

[0022] Kit 2 also includes a top plate 203, the inner side of which is fixedly connected to the sleeve 201, and the upper surface of the top plate 203 contacts the first rotating block 103. During installation, the kit 2 is first passed through the upper surface of the power strip shell from above, so that the sleeve 201 is inserted into the inside of the power strip, and the top plate 203 remains outside. Then, by screwing the plug-in component 1 into the inside of the kit 2, the lower surface of the first rotating block 103 contacts and squeezes the upper surface of the top plate 203, thereby fixing the plug-in component 1 and the kit 2 together.

[0023] The lower portion of the sleeve 201 is provided with three slots 202 . The slots 202 prevent the lower portion of the sleeve 201 from forming a complete ring shape, thereby allowing it to move toward the center after being squeezed.

[0024] The fixing member 3 includes a deformation block 302, the upper part of which is connected to a protrusion 303, which protrudes horizontally toward the outside of the deformation block 302; the inner walls of the deformation block 302 and the protrusion 303 are pressed against the outer surface of the sleeve 201; the fixing member 3 also includes an inner rod 304, the inner wall of the outer rod 101 is provided with a fixing hole 102, and the outer surface of the inner rod 304 is threadedly connected to the outer rod 101.

[0025] The fixing member 3 also includes a second rotating block 301. The upper surface of the second rotating block 301 is fixedly connected to the deforming block 302. A cross slot is provided on the upper part of the second rotating block 301. The second rotating block 301 plays the same role as the first rotating block 103, both of which drive other components to rotate. No more details are given here. The upper surface of the second rotating block 301 is also fixedly connected to the inner rod 304. The inner rod 304 is fixed by the second rotating block 301. When the second rotating block 301 rotates, the inner rod 304 can be driven to rotate for easy installation.

[0026] The outer surfaces of the outer rod 101 and the inner rod 304 are both provided with threads for easy fixation. The first rotating block 103 and the outer rod 101 are an integrally formed structure, the sleeve 201 and the top plate 203 are also an integrally formed structure, the second rotating block 301 and the deforming block 302 and the protrusion 303 are also an integrally formed structure, the deforming block 302 and the sleeve 201 are both made of plastic and have a certain deformation ability. When the lower part of the sleeve 201 is inserted into the interior of the deforming block 302, under the action of the extrusion force, the sleeve 201 is reduced toward the middle and the deforming block 302 is expanded toward the outside, so as to squeeze each other.

[0027] During installation of the present invention, first, insert the sleeve 2 through the upper surface of the power strip shell from above, insert the sleeve 201 into the inside of the power strip, and leave the top plate 203 outside. Then, screw the connector 1 into the inside of the sleeve 2, so that the lower surface of the first rotating block 103 contacts and squeezes the upper surface of the top plate 203, thereby fixing the connector 1 and the sleeve 2 together. Then, buckle the power strip shell and the bottom plate together and align them. At the same time, make the sleeve 201 and the inner rod 304 penetrate the power strip shell and the bottom plate. Place the fixing member 3 on the bottom of the power strip bottom plate, so that the protrusion 303 remains on the lower surface of the power strip bottom plate, and align the inner rod 304 with the fixing hole 102. The sleeve 201 is located above the protrusion 303 and close to it. Then, screw the fixing member 3, while preventing the plug from The connector 1 rotates, so that the inner rod 304 is inserted into the interior of the fixing hole 102. Under the action of the thread, the protrusion 303 moves upward close to the extrusion sleeve 201, so that when the lower part of the sleeve 201 is inserted into the interior of the protrusion 303 and the deformation block 302, under the action of the extrusion force, the sleeve 201 shrinks toward the middle and the deformation block 302 expands outward. From the mutual squeezing, the deformation block 302 expands and deforms, thereby increasing its contact area with the socket bottom plate to increase the fixing effect. At the same time, the sleeve 201 shrinks inward, so that the sleeve 201 is more tightly fixed to the outer rod 101 to prevent shaking during subsequent use, thereby increasing the firmness of the connector 1 and the kit 2, achieving the effect of preventing loose fixation.
