Abstract
Description
Technical Field
[0001] This utility model relates to the field of fastener technology, and in particular to a pipe clamp. Background Technology
[0002] Pipe clamps are mechanical fittings used to fix, support, or connect pipelines, and are widely used in industries such as manufacturing, construction, shipbuilding, and automotive. Their main function is to ensure stable pipeline operation and prevent damage or leakage caused by vibration, displacement, or external forces. Depending on the application scenario, U-shaped pipe clamps are typically used for temporary fixing or frequent disassembly of pipelines. U-shaped pipe clamps consist of a U-shaped clamp and bolts, primarily used to fix and connect pipelines, providing stable support and a secure fastening effect.
[0003] Existing U-shaped pipe clamps typically use a U-shaped clamp and lock it to a base plate with bolts. The locking point is usually the open end of the U-shaped clamp, which is then secured to the base plate with bolts. In this locking process, the positioning point is located at the connection point between the base plate and the U-shaped clamp; that is, the positioning point is the connection point. Using bolts to connect the two can easily cause excessive pressure on the positioning / connection point, thus limiting the load-bearing capacity of this type of U-shaped pipe clamp.
[0004] For those skilled in the art, the usual way to improve load capacity is to add reinforcing ribs or protrusions at the load position. However, for U-shaped pipe clamps, since the load position is the connection point, designing reinforcing ribs and protrusions at the threaded connection position will interfere with the thread setting. Even if the design avoids this, it will cause difficulties in the processing of the parts and increase production costs.
[0005] Therefore, how to further improve the structure of U-shaped pipe clamps to enhance their strength and load-bearing capacity, while also making them easier to position, assemble, and connect, has become the current design focus. Utility Model Content
[0006] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides a pipe clamp, which designs the U-shaped clamp as a split part and strengthens the split part to make it have better strength and tensile strength, while being convenient and reliable to combine with the base plate.
[0007] The technical solution adopted by this utility model to solve its technical problem is: a pipe clamp, including a lower base plate and a U-shaped clamp, wherein the U-shaped clamp includes two symmetrically arranged clamping pieces; each clamping piece includes, from top to bottom, a clamping head, an upper arc-shaped part, and a lower clamping plate part connected in sequence; each clamping head of the clamping piece has a through hole, and the inner wall of the through hole of any clamping piece has an internal thread; the clamping heads of the two clamping pieces are connected and fixed by a fastening bolt that is threaded into the through hole and connected to the internal thread; when the two clamping pieces are connected at the clamping heads, the two clamping pieces... The upper arc-shaped part and the lower clamping plate part form a U-shaped structure with the opening facing downwards; the inner wall of the lower clamping plate part is concave inwards to form a raised cavity, and the raised cavity protrudes outwards relative to the outer wall of the lower clamping plate part; the lower end of the lower clamping plate part has an inverted T-shaped structure, including a vertical part and a horizontal part connected sequentially from top to bottom, and the two sides of the horizontal part have upper hooks respectively; the lower bottom plate is a groove-shaped structure, and the two sides of the groove opening of the groove-shaped structure are folded downwards to form a lower folded edge; the upper hooks and the lower folded edge hooks cooperate with each other.
[0008] In the above solution, the U-shaped clamp is designed as a split unit. The connection between the U-shaped clamp and the lower base plate is achieved through the engagement of the upper hook and the lower folded edge hook. The top of the U-shaped clamp is locked by a thread to complete the overall clamping and positioning. Separating the connection point and locking point between the U-shaped clamp and the lower base plate effectively improves the overall load-bearing capacity of the pipe clamp. Furthermore, the design of the U-shaped clamp incorporates a raised cavity on the lower clamp plate, effectively increasing the surface area at the lower clamp plate, further distributing the stress, and further improving the strength and tensile strength of the clamp.
[0009] Furthermore, the raised chamber is an inverted T-shaped chamber, comprising a vertical chamber and a horizontal chamber that run sequentially from top to bottom. The horizontal chamber is located within the horizontal portion of the lower clamping plate. The raised chamber is designed to mimic the shape of the lower clamping plate, and a chamber is designed at the mating position between the clamping piece and the lower base plate to further increase the surface area, thereby improving the bonding strength.
[0010] Preferably, the vertical top section of the raised chamber has an isosceles trapezoidal structure with a wider top and narrower bottom. This change in cross-section at the top of the vertical section of the raised chamber further enhances the strength at the top position.
[0011] Furthermore, a lower support plate is embedded and fitted at the opening of the lower base plate corresponding to the opening of the U-shaped clamp. The lower support plate is supported and positioned within the opening of the U-shaped clamp, which can effectively engage and position the front and rear sides of the groove. On the other hand, when the pipe clamp is connected to the pipe fitting, it can also serve as a support at the groove position, providing effective support and limiting for the pipe fitting.
[0012] Furthermore, the lower support plate has alternating staggered protrusions with reinforcing ribs on its upper and lower end faces, which further improves the strength of the lower support plate.
[0013] Furthermore, the front and rear ends of the clamping head of the clamping piece are folded and extended with outward folded edges. The design of the outward folded edges can effectively improve the strength of the clamping head and prevent deformation when the two clamping heads are joined together.
[0014] Furthermore, the front and rear ends of the clamping piece corresponding to the upper arc-shaped part and the lower clamping plate part are respectively fitted with rubber bushings to provide further protection for the front and rear ends of the clamping piece.
[0015] The beneficial effects of this utility model are as follows: The pipe clamp provided by this utility model has a reasonable structural design. The U-shaped clamp adopts a split design. On each clamp piece, there is an outwardly raised cavity, which can effectively increase the surface area of the clamp piece and improve its tensile strength. The shape of the raised cavity is also reasonably distributed. An upper hook is designed at the open end of the clamp piece, which is used to hook and lock with the lower folded edge of the bottom plate. On the one hand, it plays a role in opposing pull positioning; on the other hand, this hook design effectively increases the connection area between the clamp piece and the bottom plate, further enhancing the load-bearing capacity. At the same time, the split design means that the clamp piece and the bottom plate are mated at the bottom, and the positioning and fastening position is at the top. The separation of the two parts can effectively distribute the positioning force on the clamp piece, avoiding tearing caused by force on a single position. The internal thread designed on the clamp head of the clamp piece also makes the threaded connection internal. The two clamp pieces can be positioned and fixed by fastening bolts without the need for additional nuts, which effectively simplifies the assembly process and makes disassembly and assembly more convenient.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components relevant to the present invention. Orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.
[0023] Example 1:
[0024] like Figures 1 to 4 The pipe clamp shown is an embodiment of this utility model.
[0025] The pipe clamp includes a lower base plate 5 and a U-shaped clamp, the U-shaped clamp including two symmetrically arranged clamping pieces 6. Each clamping piece 6, from top to bottom, includes a clamping head 61, an upper arc-shaped portion 62, and a lower clamping plate portion 63 connected in sequence. The clamping head 61 is used to engage with the fastening bolt 1 for locking and fixing. When the two clamping pieces 6 are connected at the clamping heads 61, the upper arc-shaped portion 62 and the lower clamping plate portion 63 of the two clamping pieces 6 form a U-shaped structure with the opening facing downwards. Specifically, each clamping head 61 of each clamping piece 6 has a through hole, and the inner wall of the through hole of any clamping piece 6 has an internal thread 611. The clamping heads 61 of the two clamping pieces 6 are connected and fixed by a fastening bolt 1 that is threaded into the through hole and connected to the internal thread 611.
[0026] like Figure 4 As shown, the inner wall of the lower clamping plate portion 63 is concave outward to form a raised cavity, which protrudes outward relative to the outer wall of the lower clamping plate portion 63. The lower end of the lower clamping plate portion 63 has an inverted T-shaped structure, including a vertical portion 631 and a horizontal portion 634 connected sequentially from top to bottom. The horizontal portion 634 of the lower clamping plate has upper hook portions 635 on both sides. The lower bottom plate 5 has a groove-shaped structure, and the groove edges on both sides of the groove opening are folded downward to form lower folded edges 51. The upper hook portions 635 and the lower folded edges 51 are hooked together.
[0027] The raised chamber is an inverted T-shaped chamber, comprising a vertical cavity 632 and a transverse cavity 633 running sequentially from top to bottom. The transverse cavity 633 is located within the transverse portion 634 of the lower clamping plate portion 63. The vertical cavity 632 is located within the vertical portion 631 and is positioned at the midpoint in the front-to-back direction. The top cross-section of the vertical portion 631 of the raised chamber has an isosceles trapezoidal structure with a wider top and narrower bottom. In production, the chamber can be integrally formed on the clamping plate 6 by stamping or casting during production. By varying the surface area and conforming to the shape of the lower clamping plate portion 63, the increased surface area forms the chamber, thereby improving the bonding strength.
[0028] This pipe clamp design features a split U-shaped clamp. The U-shaped clamp is connected to the lower base plate 5 via a hook engagement between the upper hook 635 and the lower folded edge 51. The top of the U-shaped clamp is locked by a thread to complete the overall clamping and positioning. Separating the connection point and locking point between the U-shaped clamp and the lower base plate 5 effectively improves the overall load-bearing capacity of the pipe clamp. The clamping piece 6 engages with the lower base plate 5 at the bottom, while the positioning and fastening point is at the top. This separation effectively distributes the positioning force across the clamping piece 6, preventing tearing caused by stress on a single location.
[0029] Meanwhile, the split design allows the internal thread 611 on the clamp head 61 of the clamping plate 6 to be internally threaded, so that the two clamping plates 6 can be positioned and fixed by the fastening bolt 1 without the need to add a nut, which effectively simplifies the assembly process and makes disassembly and assembly more convenient.
[0030] In the design of the U-shaped clamp, the raised chamber design on the lower clamp plate effectively increases the surface area of the clamping piece 6, improves the tensile strength, and the shape of the raised chamber is also reasonably distributed.
[0031] Furthermore, a hook 635 is designed at the open end of the clip 6. The hook 635 is used to hook and buckle with the folded edge 51 of the lower base plate 5. On the one hand, it plays a role in opposite pulling and positioning. On the other hand, this hook and buckle design effectively increases the connection area between the clip 6 and the lower base plate 5, which further enhances the load-bearing effect.
[0032] Example 2:
[0033] like Figures 1 to 3 The pipe clamp shown is a second embodiment of this utility model. The second embodiment adds a lower support plate 4 to the first embodiment.
[0034] Specifically, a lower support plate 4 is fitted into the opening of the lower base plate 5 at the opening position corresponding to the opening position of the U-shaped clamp. The upper and lower end faces of the lower support plate 4 are alternately staggered with reinforcing ribs 41.
[0035] The reinforcing rib 41 can effectively improve the strength of the lower support plate 4. When the lower support plate 4 is supported and set at the position corresponding to the opening of the U-shaped clamp, it can effectively be embedded and tied to the front and rear sides of the groove for positioning. On the other hand, when the pipe clamp is connected to the pipe fitting, it can also serve as a support at the groove position, providing effective support and limiting for the pipe fitting.
[0036] Example 3:
[0037] like Figures 1 to 4 The pipe clamp shown is a third embodiment of this utility model. Based on the first embodiment, the clamp head 61 has been further improved in the third embodiment.
[0038] Specifically, the front and rear ends of the clamping head 61 of the clamping piece 6 are folded and extended with outward folded edges 612. Since the locking position is located at the clamping head 61 in this design, the clamping head 61 needs to withstand a high load when locked. The design of the outward folded edges 612 can effectively increase the strength of the clamping head 61, making it less prone to deformation when the two clamping heads 61 are joined together.
[0039] Example 4:
[0040] like Figures 1 to 3 The pipe clamp shown is a fourth embodiment of this utility model. Based on the first embodiment, the fourth embodiment has rubber bushings 2 respectively engaged and fitted at the front and rear ends of the clamping piece 6 corresponding to the upper arc-shaped part 62 and the lower clamping plate part 63, providing further protection for the front and rear ends of the clamping piece 6.
[0041] For ease of installation, the rubber bushing 2 should avoid the mating position between the upper hook 635 and the lower folded edge 51 of the lower base plate 5, leaving a gap at that position and not installing the rubber bushing 2.
[0042] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
