Description

Technical Field

[0001] The invention relates to the field of pipeline installation, in particular to a push-type fastener for quick installation of pipelines. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Some pipelines, such as the water outlet pipes of fire-fighting pipelines, need to be fixed at a high place, so that the water outlet pipes are not only stably fixed under normal conditions, but also can stably discharge water when water is needed. In the prior art, a first fastener and a second fastener are usually provided for fire-fighting pipelines. The second fastener is provided with screws to fasten the first fastener. When in use, the screws need to be loosened, and then the first fastener is fastened to the square tube. The two ends of the square tube are fixed. After the pipeline is fastened to the first fastener, the first fastener is fastened by the second buckle. The second fastener is provided with screws to fasten the first fastener and the second fastener. The inventor found that the existing fasteners have the following problems:

[0004] In the prior art, when installing the pipeline, the second fastener needs to be opened relative to the first fastener, and then the pipeline is placed. After the pipeline is placed, the first fastener is closed by the second fastener, and the corresponding screws are tightened, so that the installation time of the pipeline is relatively long;

[0005] The screws at the second fastener need to be loosened and then tightened during installation, which may cause the worker to use too much force and cause the thread to slip. Once the thread slips, the entire device needs to be replaced, which prolongs the overall installation time.

[0006] The screws at the second fastener are prone to falling off during installation, which also prolongs the installation time of the pipeline.

[0007] Thus, the fastener structure in the prior art is not set reasonably, which easily leads to a long installation time for a single pipeline, and some pipelines, such as fire protection pipelines, are set in large quantities in a building, resulting in a long overall installation time for the pipelines. Summary of the invention

[0008] In view of the deficiencies in the prior art, an object of the present invention is to provide a push-on fastener for quick installation of pipelines, which can achieve quick installation of pipelines.

[0009] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0010] A push-type fastener for quick installation of pipelines, comprising a U-shaped frame, wherein the U-shaped frame is provided with a first slot along a first direction thereof so that a support frame can be arranged through the first slot, and the U-shaped frame is provided with a second slot along a second direction thereof so that a pipeline to be installed can be inserted into the second slot, the first direction and the second direction are arranged perpendicularly or intersectingly, a screw rod passes through one side of the U-shaped frame into the first slot and is movably connected with a slider, the shape of a side of the slider away from the screw rod is adapted to the shape of the pipeline to be installed, the central axis of the screw rod is arranged obliquely outwardly relative to the support frame, the screw rod is threadedly connected to the U-shaped frame, and the screw rod is rotated to move the slider so that the pipeline to be installed is quickly fixed to the support frame.

[0011] A push-on fastener for fastening pipes as described above, wherein an inclined surface is provided on one side of the U-shaped frame, a convex portion is provided on the inclined surface, a threaded hole is provided on the convex portion, and the screw rod passes through the convex portion and is connected to the threaded hole through a threaded structure, so that the screw rod can rotate relative to the U-shaped frame;

[0012] The size of the sliding block is larger than the diameter of the threaded hole, so as to effectively prevent the sliding block from being separated from the threaded hole.

[0013] A push-type quick-installation fastener for pipes as described above, wherein the length of the side where the screw is located in the U-shaped frame is greater than the length of the other side, and the width of the side where the screw is located in the U-shaped frame is greater than the width of the other side, so as to effectively enhance the strength of the side where the screw is located in the U-shaped frame;

[0014] The inner side wall of the U-shaped frame cooperates with the side surface of the slider to limit the moving direction of the slider, so that the rotational movement of the slider is restricted by the U-shaped frame, and the moving path of the slider is restricted by the U-shaped frame under the drive of the screw.

[0015] A push-type fastener for quick installation of pipelines as described above, wherein a first groove is provided on the side of the slider, a guide rail matching the first groove is provided on the inner side wall of the U-shaped frame, and first grooves are provided on opposite sides of the slider, and the first grooves are provided along the length direction of the slider;

[0016] Alternatively, in another embodiment, a protrusion is provided on the side wall of the slider, and a second groove cooperating with the protrusion is provided on the inner side wall of the U-shaped frame, and the protrusion is provided along the length direction of the slider.

[0017] As described above, a push-type fastener for quick installation of pipelines, because the pipeline to be installed is usually a circular pipeline, the contact area between the slider and the pipeline is limited, and a section of the slider away from the screw rod is set as a tip section, and a third groove is set at the tip section to contact the pipeline to be installed, and the height of the third groove is the same as the height of the slider;

[0018] The third groove is a V-shaped groove or an arc-shaped groove. The provision of the third groove enables the slider to be in close contact with the pipeline to be installed during the movement toward the pipeline to be installed, thereby effectively ensuring the stability of the pipeline.

[0019] As described above, a push-type quick-installation fastener for pipelines has an inverted T-slot on one side where the slider is connected to the screw rod, and a fixing plate is provided at one end of the screw rod. The diameter of the fixing plate is larger than the diameter of the screw rod. The fixing plate is located at the wider part of the inverted T-slot to facilitate fixing the screw rod and being movably connected to the screw rod. The two sides of the inverted T-slot are open so that the screw rod and the fixing plate can enter the inverted T-slot of the slider.

[0020] In the push-type quick-installation pipe fastener as described above, the screw is located on the outer side of the U-shaped frame and a locking nut is arranged in an annular direction. The setting of the locking nut facilitates the rotation of the screw. After the screw is rotated into place, the screw is locked by the locking nut.

[0021] A push-type fastener for quick installation of pipelines as described above, wherein the U-shaped frame comprises a first U-frame, a second U-frame and a third U-frame connected in sequence, the length of the second U-frame is less than the length of the third U-frame, the length of the third U-frame is less than the length of the first U-frame, the length of the first U-frame is greater than the length of the third U-frame, and the width of the first U-frame is greater than the width of the third U-frame, so that the strength of the U-shaped frame at the screw setting position is effectively guaranteed, and the moving range of the slider is guaranteed;

[0022] The screw rod is arranged through the side of the first U frame.

[0023] According to the push-type fastener for quick installation of pipelines as described above, the first U-frame and the third U-frame are respectively provided with fixing parts to support both sides of the first U-frame and the third U-frame, and the distance between the fixing parts and the middle connecting section of the first U-frame and the third U-frame is greater than the width of the support frame. The fixing parts are provided to support both sides of the first U-frame or the third U-frame, enhance the strength of the first U-frame and the third U-frame, and prevent the deformation problem of the U-frame;

[0024] A connecting plate is provided at one end of the first U frame away from the supporting frame, so as to effectively enhance the structural strength of the first U frame.

[0025] In a second aspect, the present invention further provides a method for installing a fire protection pipeline, using the push-type quick installation pipeline fastener, comprising the following contents:

[0026] The support frame is passed through a push-type quick-installation pipeline fastener through the first clamping slot;

[0027] Both ends of the support frame are fixed by side brackets;

[0028] Insert the water outlet pipe of the fire protection pipeline into the second slot;

[0029] Compared with the U-shaped frame rotating screw, since the slider is movably connected to the screw, the U-shaped frame restricts the slider to rotate with the screw, thereby converting the rotational motion of the screw into the linear motion of the slider, so that the slider is stably abutted against the water outlet pipe, realizing the rapid installation of the fire protection pipeline.

[0030] The beneficial effects of the present invention are as follows:

[0031] 1) In the present invention, only one U-shaped frame is provided, and no other fasteners are provided. The structure is simple. The screw rod and the slider are fixed to the U-shaped frame before the pipeline is installed. When the pipeline is installed, it is only necessary to insert the pipeline into the second slot, and adjust the screw rod relative to the U-shaped frame so that the slider abuts against the pipeline to be installed. The pipeline can be stably fixed to the U-shaped frame, that is, stably fixed to the support frame. The installation speed is faster than that of two fasteners in the prior art.

[0032] 2) In the present invention, before the pipeline is installed and inserted into the second slot, it is not necessary to loosen the screw, because a certain space is reserved. The screw is rotated only after the pipeline is installed and inserted. Even if too much force is used during the screw rotation, it will not cause the U-shaped frame and the screw to slip. Finally, the screw can be locked with a locking nut. Even if the problem of slipping occurs, there is no need to replace the U-shaped frame; the screw passes through one side of the U-shaped frame and is connected to the slider. The size of the slider is larger than the diameter of the threaded hole, which effectively avoids the problem of accidental falling off of the screw from the threaded hole and avoids the problem of long installation time caused by screw slipping or falling off.

[0033] 3) The second slot in the present invention can be engaged with the pipeline to be installed to preliminarily fix the pipeline to be installed. The central axis of the screw is inclined outward relative to the support frame to press the pipeline to be installed from the outside, thereby ensuring stable fixation of the pipeline to be installed under the premise of rapid installation.

[0034] 4) In the present invention, the inner side wall of the U-shaped frame cooperates with the side of the slider, and the two can cooperate with each other in the form of a guide rail groove or a groove protrusion, effectively ensuring the moving path of the slider and effectively preventing the slider from accidentally falling off from the U-shaped frame.

[0035] 5) The slider structure of the present invention is reasonably arranged. A third groove is arranged on the side of the slider away from the screw rod to contact with the pipeline to be installed, thereby ensuring a close fit between the slider and the pipeline to be installed. An inverted T-shaped groove is arranged on the other side of the slider, and the fixing plate is located at the wider part of the inverted T-shaped groove to facilitate fixing the screw rod and being movably connected with the screw rod.

[0036] 6) The U-shaped frame structure of the present invention is reasonably arranged, the length and width of the first U-shaped frame are greater than the length and width of the third U-shaped frame, which effectively ensures the strength of the U-shaped frame at the screw setting position, and is conducive to setting a guide rail or a second groove on the inner wall of the first U-shaped frame to ensure the moving range of the slider;

[0037] Furthermore, fixing parts are respectively arranged at the first U-frame and the third U-frame to enhance the strength of the first U-frame and the third U-frame and prevent deformation of the U-frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0053] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless otherwise explicitly stated in the present invention, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof;

[0054] As introduced in the background technology, the structure of the fasteners for pipe installation in the prior art is unreasonable, resulting in the problem that the pipe installation time is not fast enough. In order to solve the above technical problems, the present invention proposes a push-type quick installation fastener for pipes.

[0055] Embodiment 1

[0056] In a typical embodiment of the present invention, reference is made to Figure 1 , Figure 2 As shown, a push-type fastener for quick installation of pipelines includes a U-shaped frame 2, a first card slot 5 is arranged along the first direction of the U-shaped frame 2 so that the support frame 2 can be arranged through the first card slot 5, and a second card slot 4 is arranged along the second direction of the U-shaped frame 2 so that the pipeline to be installed can be inserted into the second card slot 4, the first card slot is arranged along the depth direction of the U-shaped frame, and the second card slot is arranged along the height direction of the U-shaped frame, the first direction and the second direction are arranged perpendicularly so that the pipeline to be installed can be perpendicular to the support frame, a screw rod 1 passes through one side of the U-shaped frame 2 into the first card slot and is movably connected to a slider 3, the shape of the side of the slider away from the screw rod is adapted to the shape of the pipeline to be installed, the central axis of the screw rod is arranged obliquely outward relative to the support frame, the screw rod is threadedly connected to the U-shaped frame, and the screw rod is rotated to move the slider to quickly fix the pipeline to be installed on the support frame.

[0057] It should be noted that a slope is provided on one side of the U-shaped frame 2, and a convex portion 2-5 is provided on the slope, the convex portion protrudes from the slope, and a threaded hole is provided on the convex portion 2-5. Of course, the slope is provided with an opening corresponding to the threaded hole. The setting of the convex portion effectively enhances the strength of the U-shaped frame at this point, and is also conducive to ensuring the height of the threaded hole, effectively avoiding the problem of thread slippage in the threaded structure here. The screw is vertically arranged with the slope, and the screw passes through the convex portion and is connected to the threaded hole through the threaded structure, so that the screw can rotate relative to the U-shaped frame;

[0058] The size of the slider 3 specifically refers to that the width and thickness of the slider are greater than the diameter of the threaded hole to effectively prevent the slider from detaching from the threaded hole, and the thickness of the slider, that is, the height of the slider, is adapted to the height of the first slot in the U-shaped frame.

[0059] It should be noted that the inner wall of the U-shaped frame 2 cooperates with the side of the slider to limit the moving direction of the slider 3, so that the rotational movement of the slider is restricted by the U-shaped frame 2, and the moving path of the slider is restricted by the U-shaped frame under the drive of the screw.

[0060] Specifically, refer to Figure 3 and Figure 5 As shown, a first groove is provided on the side of the slider 3 (the upper side and the lower side of the slider when in use), and a guide rail 2-6 matching with the first groove 3-4 is provided on the inner side wall of the U-shaped frame 2. The guide rail can be inserted into the first groove 3-4. The shape of the guide rail is compatible with the shape of the first groove. The first groove 3-4 is provided on both opposite sides of the slider 3. The first groove is provided along the length direction of the slider 3. The cooperation between the slider and the guide rail also prevents the slider from accidentally falling off from the U-shaped frame.

[0061] It is understandable that there is an angle between the length direction of the guide rail and the length direction of the support frame to ensure that the screw drives the slider to press the pipeline to be installed from the outside.

[0062] Because the pipeline to be installed is usually a circular pipeline, the contact area between the slider and the pipeline is limited, and a section of the slider away from the screw is set as a tip section 3-2, that is, the width of the slider away from the screw gradually decreases, and a third groove 3-1 is set at the tip section to contact the pipeline to be installed. The height of the third groove is the same as the height of the slider, and the end of the slider away from the screw is a straight section on both sides of the third groove;

[0063] Specifically, the third groove 3-1 is a V-shaped groove. Figure 6 As shown, the third groove is an arc groove. The setting of the tip section of the third groove can make the slider closely contact with the pipeline to be installed during the movement toward the pipeline to be installed, effectively ensuring the stability of the pipeline.

[0064] refer to Figure 7As shown, an inverted T-shaped groove 3-3 is provided on one side where the slider 3 is connected to the screw rod, and the inverted T-shaped groove 3-3 is provided along the width direction of the slider; Figure 8 As shown, the screw 1 is provided with an external thread structure 1-2 in an annular direction, and a fixing plate 1-3 is provided at one end of the screw. The diameter of the fixing plate is larger than the diameter of the screw. The fixing plate is located at the wider part of the inverted T-slot to facilitate fixing the screw and being movably connected with the screw. The two sides of the inverted T-slot 3-3 are openly provided so that the screw and the fixing plate can enter the inverted T-slot of the slider.

[0065] The screw 1 is located on the outer side of the U-shaped frame and a locking nut 1-1 is arranged in an annular direction. The locking nut 1-1 can be a butterfly nut. The setting of the locking nut facilitates the rotation of the screw. After the screw is rotated into place, the screw is locked by the locking nut.

[0066] In addition, refer to Figure 1 As shown, the U-shaped frame includes a first U-frame 2-1, a second U-frame 2-2 and a third U-frame 2-3 connected in sequence, the length of the second U-frame is less than the length of the third U-frame, the width of the second U-frame (along the length direction of the support frame) is adapted to the outer diameter of the pipeline to be installed, the width of the second U-frame is greater than the widths of the first U-frame and the third U-frame, the length of the third U-frame (along the width direction of the support frame) is less than the length of the first U-frame, and the width of the first U-frame is greater than the width of the third U-frame, so that the strength of the U-shaped frame at the screw setting position is effectively guaranteed, and the moving range of the slider is guaranteed;

[0067] It can be understood that the screw rod is arranged through the side of the first U frame, so that a slope is arranged on the side of the first U frame away from the second U frame, and the screw rod is arranged through the slope of the first U frame.

[0068] In addition, during manufacturing, the first U-frame, the second U-frame and the third U-frame are manufactured as one body to form a U-shaped frame.

[0069] The first U-frame and the third U-frame are respectively provided with fixing parts to support both sides of the first U-frame and the third U-frame. The distance between the fixing parts and the middle connecting sections of the first U-frame and the third U-frame is greater than the width of the support frame. The fixing parts are provided to support both sides of the first U-frame or the third U-frame, enhance the strength of the first U-frame and the third U-frame, and prevent the deformation of the U-frame.

[0070] In this embodiment, openings are respectively provided on both sides of the first U frame and the third U frame, and the fixing member can be a fixing pin 10. The fixing pin 10 can select an existing grooved retaining spring pin. The grooved retaining spring pin passes through the openings on both sides of the first U frame or the third U frame and is locked by the retaining spring.

[0071] It should be noted that a connecting plate 2-4 is provided at one end of the first U frame away from the supporting frame, and the connecting plate is perpendicular to the two side surfaces of the first U frame, thereby effectively enhancing the structural strength of the first U frame.

[0072] The fastener provided in the present embodiment is only provided with one U-shaped frame, and no other fastener is provided. The structural setting is simple. The screw and the slider are fixed to the U-shaped frame in advance before the pipeline is installed. When the pipeline is installed, it is only necessary to insert the pipeline into the second slot, and adjust the screw relative to the U-shaped frame so that the slider abuts against the pipeline to be installed. The pipeline can be stably fixed to the U-shaped frame, that is, stably fixed to the support frame, so that a single pipeline can be quickly installed.

[0073] Embodiment 2

[0074] The difference between this embodiment and the first embodiment is that:

[0075] The two opposite side walls of the slide block facing the U-shaped frame are respectively provided with protrusions, the inner side wall of the U-shaped frame is provided with a second groove matched with the protrusion, and the protrusion is arranged along the length direction of the slide block.

[0076] Embodiment 3

[0077] This embodiment provides a method for installing a fire protection pipeline. Figure 4 As shown, a push-type quick-installation pipeline fastener described in Embodiment 1 or Embodiment 2 is used, including the following contents:

[0078] When a push-type fastener for quick installation of pipelines is factory set, the slider 3 is located inside the first U frame and will not enter the second slot, so that it is convenient to insert the pipeline to be installed into the second slot;

[0079] The support frame is arranged through a push-type quick-installation pipeline fastener through the first card slot, so that the U-shaped frame and the support frame are located in the same plane, and the support frame 6 can be a square tube;

[0080] The two ends of the support frame 6 are fixed by side brackets 9, and the side brackets 9 are used to fix the two ends of the square tube in the prior art;

[0081] Insert the water outlet pipe 7 of the fire-fighting pipeline into the second clamping groove 4, the water outlet end of the water outlet pipe 7 is arranged below the U-shaped frame 2, and the top end of the water outlet pipe 7 is connected to the metal hose 8;

[0082] Compared with the U-shaped frame rotating screw, since the slider is movably connected to the screw, the U-shaped frame restricts the slider to rotate with the screw, thereby converting the rotational motion of the screw into the linear motion of the slider, so that the slider is stably abutted against the water outlet pipe, realizing the rapid installation of the fire protection pipeline.

[0083] Furthermore, when installing the fire-fighting pipeline, the directions of the first clamping slot and the second clamping slot are perpendicular to each other.

[0084] It needs to be explained that the push-type quick-installation pipe fastener provided in the first or second embodiment can be used not only for the installation of fire-fighting pipes, but also for the installation of other pipes.

[0085] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
