Description

Technical Field

[0001] The present invention relates to the technical field of wire fixing, and particularly to an auxiliary fixing device for water, heating and electrical wires. Background Art

[0002] Water, heating, and electricity are all essential in people's lives and constantly affect the quality of people's lives. With the improvement of people's economic level and the gradual opening of concepts, the popularization of heating and smart homes has continuously improved people's living standards. However, in the installation of smart homes and water, heating, and electricity, they are all connected by wires. When installing, the wires are prone to being messy and entangled. Therefore, the currents will affect each other, thereby affecting their operation; for modern building construction, water and heating construction is the basis for achieving the engineering construction goals and functional goals. During the construction process of equipment such as water, heating, and electricity, since most of them involve the setting of wire lines, and these lines need to be fixed.

[0003] The existing wire fixing structure is combined by two semi-circular snap ring structures to clamp the wire; the two semi-circular snap rings are generally arranged on the left and right sides or the upper and lower sides. When the semi-circular snap rings on the left and right sides are combined, the wire needs to be placed between the two semi-circular snap rings from the upper side. However, there is no device to support the wire under the two semi-circular snap rings, so the wire is easily disengaged from the gap between the lower sides of the two semi-circular snap rings; through the semi-circular snap rings combined up and down, the semi-circular snap ring on the upper side will hinder the wire from being placed between the two semi-circular snap rings. In some occasions with a small installation space, the staff needs to pass the end of the wire through between the two semi-circular snap rings to fix the wire, and the operation is relatively cumbersome. Summary of the Invention

[0004] The purpose of the present invention is to provide an auxiliary fixing device for water, heating and electrical wires to solve the problems raised in the background art.

Detailed implementation manners

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments; in the drawings or descriptions, similar or identical parts are denoted by the same reference numerals, and in actual applications, the shapes, thicknesses or heights of the various components can be enlarged or reduced. The various embodiments listed in the present invention are only used to illustrate the present invention and are not intended to limit the scope of the present invention. Any obvious modification or change made to the present invention does not depart from the spirit and scope of the present invention.

[0028] In the following embodiments, the left-right, up-down positions of the various components shown in the drawings are only one arrangement method, and the specific positions are set according to specific needs.

[0029] In one embodiment, as Figures 1-4As shown in the figure, a water heating and electric circuit auxiliary fixing device includes a plurality of card seat mechanisms that can be detachably connected together. The card seat mechanism includes a fixed base 100 with a ground connection part 120 and an arc-shaped pressing cover 200 located on the upper side of the fixed base 100. A semi-circular wire groove 110 capable of correspondingly clamping the wire with the arc-shaped pressing cover 200 is arranged on the upper surface of the fixed base 100. Extension plate strips 210 are arranged on both side parts of the arc-shaped pressing cover 200. A locking cavity 140 is provided on one side part of the fixed base 100, and a locking unit 800 is arranged inside the locking cavity 140. A covering connection component 400 is arranged on one side of the upper surface of the fixed base 100, and the top of the covering connection component 400 is connected to one of the extension plate strips 210 through a pressing part 230. The covering connection component 400 includes a support rod 410, a rotating cylinder 420, and a lock body component. The rotating cylinder 420 is rotatably arranged on the surface of the fixed base 100, and the lower end of the rotating cylinder 420 extends into the locking cavity 140. The support rod 410 slidably penetrates through the rotating cylinder 420 and is in a relative position with the locking unit 800. The rotating cylinder 420 is connected to the pressing part 230 through a releasing and fixing spring part 430. The lock body component is arranged at the bottom of the support rod 410. The lock body component can be inserted into the locking unit 800 and is locked and fixed by the locking unit 800. Two side pressing components 300 are further arranged on the upper surface of the fixed base 100, respectively located on both sides of the semi-circular wire groove 110. The side pressing components 300 are connected to the upper surface of the fixed base 100 in a damped sliding manner. The side surface of the side pressing component 300 facing the semi-circular wire groove 110 can be pressed against the surface of the wire inside the semi-circular wire groove 110 in a rolling manner. When the arc-shaped pressing cover 200 presses on the wire from the top, the two extension plate strips 210 can abut against the side parts of the side pressing components 300 away from the semi-circular wire groove 110 to limit the side pressing components 300 from moving away from the semi-circular wire groove 110.

[0030] In the embodiment of the present invention, in the initial state, the side pressure component 300 extends beyond the edge of the semicircular wire groove 110 toward one side of the semicircular wire groove 110 by a small distance, that is, the distance between the two side pressure components 300 is slightly smaller than the diameter of the semicircular wire groove 110. Since the rotating cylinder 420 is rotatable, the arc-shaped pressure cover 200 is located at the front side or the rear side of the semicircular wire groove 110, and the wire is placed inside the semicircular wire groove 110 from the middle part thereof to avoid interference with the arc-shaped pressure cover 200. When the wire is placed in the semicircular wire groove 110, the arc-shaped pressure cover 200 is placed in the semicircular wire groove 110. 0, the two side pressure components 300 are pressed against the side surface of the upper half of the wire from the side, so that before the arc-shaped pressure cover 200 is not covered, the wire can be restricted from coming out of the semicircular wire groove 110; when the arc-shaped pressure cover 200 is covered, the staff rotates the arc-shaped pressure cover 200 and makes the arc-shaped pressure cover 200 rotate to a position opposite to the semicircular wire groove 110, presses the arc-shaped pressure cover 200 and makes the arc-shaped pressure cover 200 close to the semicircular wire groove 110, the support rod 410 moves downward and the lock body assembly is gradually closed. The locking unit 800 is gradually inserted into the locking unit 800, and the locking unit 800 locks the lock body assembly to limit the rotation and upward bounce of the support rod 410. At this time, the arc-shaped pressure cover 200 covers the wire and presses the wire to effectively fix the wire. At the same time, the extension strip 210 also presses on the side of the corresponding side pressure component 300 away from the semicircular wire groove 110, so that the side pressure component 300 is restricted to move toward the side away from the semicircular wire groove 110, thereby effectively fixing the wire without the need for the wire to be placed in the semicircular wire groove 110 from the end. and the arc-shaped pressure cover 200, thereby improving the convenience of operation for the staff; when disassembling, the locking unit 800 releases the lock on the lock body assembly, and the support rod 410 automatically moves up under the elastic force of the release spring part 430, so that the arc-shaped pressure cover 200 moves up and no longer covers the top of the wire, and the arc-shaped pressure cover 200 and the support rod 410 are rotated, thereby facilitating the removal of the fixation of the wire and facilitating the maintenance of the line; wherein, the central angle corresponding to the curvature of the arc-shaped pressure cover 200 is less than 180 degrees.

[0031] In one embodiment, Figures 2-5As shown, two side plate members 130 are provided on the upper surface of the fixed base 100, which are respectively located on both sides of the semi-circular wire groove 110. The side pressing member 300 includes a movable plate 310 and a side pressing roller member 320. The bottom of the movable plate 310 is slidably connected to the upper surface of the fixed base 100. The movable plate 310 is located between the side plate member 130 and the semi-circular wire groove 110, and the movable plate 310 is connected to the side plate member 130 by a side pressing spring 340. The side pressing roller member 320 is rotatably provided on the side surface of the movable plate 310 facing the semi-circular wire groove 110, and the axis of the side pressing roller member 320 is parallel to the center line of the semi-circular wire groove 110. The surface of the side pressing roller member 320 is provided with circumferential damping strips 330 distributed along its axis direction. In the embodiment of the present invention, in the initial state, under the elastic force of the side pressing spring 340, the movable plate 310 approaches the semi-circular wire groove 110, and the distance between the side pressing roller members 320 in the two side pressing members 300 is less than the diameter of the semi-circular wire groove 110, so that the wire can be easily pressed into the semi-circular wire groove 110 from between the two side pressing roller members 320. Then, the two side pressing roller members 320 abut against the upper part of the wire from both sides, restricting the wire from coming out to a certain extent. When the arc-shaped pressing cover 200 covers the top of the wire, the side pressing roller member 320 abuts against the side of the wire, and the plurality of circumferential damping strips 330 restrict the wire from moving along the axial direction of the semi-circular wire groove 110, preventing the wire from moving due to pulling.

[0032] In one embodiment, as Figures 2-5 shown, inclined surface abutting portions 220 are provided at the bottoms of the two outer extension plate strips 210. An upper abutting plate 350 facing away from the side pressing roller member 320 is provided at the top of the movable plate 310. The end of the upper abutting plate 350 away from the movable plate 310 is inclined downward. When the arc-shaped pressing cover 200 covers the wire, the inclined surface abutting portion 220 abuts against the upper abutting plate 350 in the direction of inclined surface contact. In the embodiment of the present invention, after the arc-shaped pressing cover 200 covers the top of the wire, due to the abutment of the inclined surface abutting portion 220 and the upper abutting plate 350, the inclined surface abutting portion 220 can restrict the side pressing member 300 from moving away from the semi-circular wire groove 110 and apply a driving force to the side pressing member 300 in the direction towards the semi-circular wire groove 110, ensuring that the side pressing roller member 320 presses the side of the wire tightly.

[0033] In one embodiment, as Figures 2-7As shown, the lock body assembly includes a fixed disk 440, a lower top-opening part 450, and an upper top-opening part 460. The fixed disk 440 is fixed on the support rod 410. The upper top-opening part 460 is slidably arranged on the support rod 410, and a gap spring part 470 is connected between the upper top-opening part 460 and the fixed disk 440. The lower top-opening part 450 is fixed at the bottom of the support rod 410. The lower surface of the lower top-opening part 450 is an inclined surface and the upper surface of the upper top-opening part 460 is an inclined surface. The locking unit 800 includes a locking cylinder 810 and two rebound limiting parts. The locking cylinder 810 is arranged inside the locking cavity 140 and is in a position corresponding to the rotating cylinder 420. The outer wall of the locking cylinder 810 is fixedly connected to the inner wall of the locking cavity 140 through at least one hollow connecting part 820. The rebound limiting part is arranged inside the hollow connecting part 820 in an elastic damping manner, and one end of the rebound limiting part can extend into the locking cylinder 810. In the embodiment of the present invention, when the bottom of the support rod 410 moves down to the inside of the locking cylinder 810, the lower top-opening part 450 first contacts the end of the rebound limiting part inside the locking cylinder 810, and the lower top-opening part 450 completely presses the rebound limiting part into the hollow connecting part 820. Until the lower top-opening part 450 is completely below the rebound limiting part, the rebound limiting part automatically rebounds between the upper top-opening part 460 and the lower top-opening part 450. The rebound limiting part can block the backward movement of the lower top-opening part 450. At this time, the arc-shaped cover 200 covers the upper side of the wire. When disassembling, the staff continues to press the top of the support rod 410. The upper top-opening part 460 acts on the rebound limiting part and makes the rebound limiting part retract into the hollow connecting part 820. At this time, the rebound limiting part also acts on the upper side of the upper top-opening part 460 and makes the upper top-opening part 460 approach the lower top-opening part 450. Thus, the lower top-opening part 450 and the upper top-opening part 460 are attached to each other and form a rotating body with a bulge in the middle and conical surfaces at both ends. Thus, the end of the rebound limiting part contacts the conical surface at the top of the rotating body. Then, under the elastic force of the unlocking spring part 430, the support rod 410 moves upward, the lower top-opening part 450 and the upper top-opening part 460 disengage from the locking cylinder 810, and further, the arc-shaped cover 200 releases the covering of the wire.

[0034] In one embodiment, as Figures 2-7As shown, the lower top-opening part 450 and the upper top-opening part 460 are both conical bodies. The conical surface of the lower top-opening part 450 faces downward and the conical surface of the upper top-opening part 460 faces upward. The rebound limiting part includes a limiting movable part 830 and a check blocking part 860. The limiting movable part 830 is slidably arranged inside the hollow connecting part 820, and the check blocking part 860 is arranged at the end of the limiting movable part 830 facing the center of the locking cylinder 810. The upper surface of the check blocking part 860 is an inclined surface; the other end of the limiting movable part 830 extends to the outside of the fixed base 100 and is provided with an outer plate member 840. The outer plate member 840 is connected to the outer wall of the fixed base 100 through a locking spring member 850; in the embodiment of the present invention, when the supporting rod 410 moves downward, the lower surface of the lower top-opening part 450 contacts the upper surface of the check blocking part 860. The lower top-opening part 450 can exert a lateral pushing force on the check blocking part 860. The check blocking part 860 is stressed and pushes the limiting movable part 830 to move toward the side away from the center of the locking cylinder 810. At this time, the locking spring member 850 is stretched; when the lower top-opening part 450 is below the check blocking part 860, under the elastic force of the check blocking part 860, the check blocking part 860 moves back to the inside of the locking cylinder 810 and the upper surface of the lower top-opening part 450 contacts the lower surface of the check blocking part 860. The check blocking part 860 blocks the upward movement of the lower top-opening part 450; when the upper top-opening part 460 moves downward, the edge of the upper top-opening part 460 contacts the upper surface of the check blocking part 860. The check blocking part 860 is stressed and pushes the limiting movable part 830 to move toward the side away from the center of the locking cylinder 810. The check blocking part 860 retracts into the locking cylinder 810. When the upper top-opening part 460 is below the check blocking part 860, the end of the check blocking part 860 contacts the upper surface of the upper top-opening part 460. The check blocking part 860 exerts a downward pressure on the upper top-opening part 460. The upper top-opening part 460 moves downward and fits with the lower top-opening part 450. Thus, the upper top-opening part 460 and the lower top-opening part 450 fit together to form a rotating body with conical surfaces at both ends. When the staff releases the top of the supporting rod 410, under the elastic force of the unlocking spring part 430, the supporting rod 410 quickly moves upward, driving the lower top-opening part 450 and the upper top-opening part 460 to move upward. Since the upward movement of the upper top-opening part 460 will laterally push the check blocking part 860 and make it retract into the hollow connecting part 820, the check blocking part 860 will not limit the upward movement of the lower top-opening part 450; thus, automatic unlocking is achieved.

[0035] In one embodiment, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 8As shown, one side of the fixed base 100 is provided with a plug fastening groove 500 and the other side is provided with a fastening plug cavity 600. Between two adjacent card seat mechanisms, the plug fastening groove 500 on one fixed base 100 can be inserted into the fastening plug cavity 600 of another fixed base 100. Two guiding grooves 610 are provided on the outer wall of the fixed base 100, and the lower ends of the guiding grooves 610 extend into the fastening plug cavity 600. The top of the guiding groove 610 communicates with the locking cavity 140. A clamping member 700 is arranged inside the guiding groove 610. When the plug fastening groove 500 is inserted into the corresponding fastening plug cavity 600, the clamping member 700 can clamp the plug fastening groove 500 to prevent the plug fastening groove 500 from disengaging from the fastening plug cavity 600. In the embodiment of the present invention, between two adjacent card seat mechanisms, after the plug fastening groove 500 is inserted into the fastening plug cavity 600 and fastened by the clamping member 700, the two card seat mechanisms can be connected together, and multiple wires can be fixed side by side. At the same time, after the clamping member 700 releases the fixation of the plug fastening groove 500, the two card seat mechanisms can be separated, which is convenient for adjusting the number of card seat mechanisms according to the number of wires.

[0036] In one embodiment, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 8As shown, two braking grooves 510 are provided on the upper surface of the plug fastening groove 500. The clamping member 700 includes two limiting insertion rods 720. The two limiting insertion rods 720 are respectively slidably arranged inside the corresponding guiding grooves 610, and a relief inclined surface 730 facing the socket of the fastening insertion cavity 600 is provided at the bottom of the limiting insertion rod 720. The tops of the two limiting insertion rods 720 are fixedly connected through a connecting rod member 710, and an upper guiding rod 740 penetrating the top wall of the locking cavity 140 is provided on the connecting rod member 710. A top plate portion 760 is provided at the top of the upper guiding rod 740, and the top plate portion 760 is connected to the upper surface of the fixed base 100 through a fastening spring portion 750. In the embodiment of the present invention, when the plug fastening groove 500 starts to be inserted into the fastening insertion cavity 600, the front end of the plug fastening groove 500 acts on the relief inclined surface 730 to move the limiting insertion rod 720 upward, so that the upper guiding rod 740 moves upward and the fastening spring portion 750 is stretched. When the plug fastening groove 500 is completely inserted into the fastening insertion cavity 600, the relief inclined surface 730 corresponds to the braking groove 510. Under the elastic force of the fastening spring portion 750 restoring deformation, the upper guiding rod 740 and the two limiting insertion rods 720 move downward, so that the bottom of the limiting insertion rod 720 is inserted into the braking groove 510, thereby restricting the plug fastening groove 500 from detaching from the fastening insertion cavity 600. An upper pressing portion 240 is provided on the side of the pressing portion 230 on the upper side of the covering connection assembly 400. The upper pressing portion 240 corresponds to the upper guiding rod 740. When the arc-shaped cover 200 covers the electric wire inside the semi-circular wire groove 110, the upper pressing portion 240 presses on the upper guiding rod 740, thereby restricting the upward movement of the upper guiding rod 740, and further restricting the upward movement of the limiting insertion rod 720, ensuring the connection tightness between the plug fastening groove 500 and the fastening insertion cavity 600.

[0037] The above embodiment provides an auxiliary fixing device for water heating electric lines, wherein, since the rotating cylinder 420 is rotatable, the arc-shaped pressing cover 200 is located at the front side or the rear side of the semicircular wire groove 110, and the wire is placed inside the semicircular wire groove 110 from the middle part thereof to avoid interference with the arc-shaped pressing cover 200. When the wire is placed inside the semicircular wire groove 110, the two side pressure components 300 press against the side surface of the upper half of the wire from the side, thereby limiting the wire from escaping from the semicircular wire groove 110 before the arc-shaped pressing cover 200 is closed; when closing the arc-shaped pressing cover 200, the staff rotates the arc-shaped pressing cover 200 and rotates the arc-shaped pressing cover 200 to a position opposite to the semicircular wire groove 110, presses the arc-shaped pressing cover 200 and makes the arc-shaped pressing cover 200 approach the semicircular wire groove 110, the support rod member 410 moves downward, and the lock body assembly is gradually inserted into the locking unit 800, and the lock is locked. The fixing unit 800 locks the lock body assembly to limit the support rod member 410 from rotating and bouncing upward. At this time, the arc-shaped pressure cover 200 covers the wire and presses the wire to effectively fix the wire. At the same time, the extended plate 210 also presses on the side of the corresponding side pressure component 300 away from the semicircular wire groove 110, so that the side pressure component 300 is restricted from moving toward the side away from the semicircular wire groove 110, thereby effectively fixing the wire and there is no need to place the wire from the end between the semicircular wire groove 110 and the arc-shaped pressure cover 200, thereby improving the convenience of operation for the staff; when disassembling, the locking unit 800 releases the lock of the lock body assembly, and the support rod member 410 automatically moves upward under the elastic force of the release spring part 430, so the arc-shaped pressure cover 200 moves upward and no longer covers the top of the wire, and the arc-shaped pressure cover 200 and the support rod member 410 are rotated, thereby facilitating the removal of the fixation of the wire and facilitating the maintenance of the line.

[0038] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
