Description

Technical Field

[0001] This application relates to the technical field of rod connection, and in particular to a connecting piece for rods. Background Art

[0002] A rod is a basic component commonly used for making guardrails and large tent supports.

[0003] In the prior art, when connecting the ends of two rods, generally, connecting pieces such as snap fasteners or bolts are used to fix the two rods. Subsequently, when the user disassembles and assembles the connecting piece between the two rods, special tools such as snap pliers or screwdrivers must be used, making the disassembly and assembly of the connecting piece for rods rather troublesome.

[0004] In view of this, a connecting piece for rods is needed. Utility Model Content

[0005] In order to solve the problem that the connecting piece for rods in the prior art must use special tools for disassembly and assembly, and the disassembly and assembly is rather troublesome, this application provides a connecting piece for rods.

[0006] This application provides a connecting piece for rods, adopting the following technical solution: including a clamping sleeve, a first connecting rod, and a second connecting rod. One end of the clamping sleeve is sleeved on the first connecting rod and connected to the first connecting rod, and the port at the other end of the clamping sleeve forms an insertion port;

[0007] One end of the second connecting rod can be inserted into the insertion port to abut against the first connecting rod, and the second connecting rod can be clamped with the clamping sleeve.

[0008] By adopting the above technical solution, when it is necessary to connect the first connecting rod and the second connecting rod, the user can first align the second connecting rod with the insertion port, and then insert one end of the second connecting rod into the insertion port until it abuts against the end of the first connecting rod, so that the second connecting rod can be connected to the first connecting rod by clamping with the clamping sleeve, thereby realizing the quick connection between the first connecting rod and the second connecting rod; when it is necessary to disassemble the first connecting rod and the second connecting rod, the user can directly pull out the second connecting rod from the clamping sleeve, so that the user can disassemble and assemble the first connecting rod and the second connecting rod by hand without using special tools, thus facilitating the user to disassemble and assemble the rods.

[0009] Specifically, a first annular clamping groove is circumferentially formed on the rod body of the first connecting rod, and a first annular groove clamping member is provided on the inner wall of the clamping sleeve. The first annular groove clamping member can be inserted into the first annular clamping groove and abut against the groove wall of the first annular clamping groove;

[0010] A second annular clamping groove is circumferentially formed on the rod body of the second connecting rod, and a second ring groove clamping member is provided on the inner wall of the clamping sleeve. The second ring groove clamping member can be inserted into the second annular clamping groove and abut against the groove wall of the second annular clamping groove.

[0011] By adopting the above technical solution, the clamping sleeve can be clamped with the first connecting rod through the cooperation of the first ring groove clamping member and the first annular clamping groove, and can also be clamped with the second connecting rod through the cooperation of the second ring groove clamping member and the second annular clamping groove.

[0012] Furthermore, both the first ring groove clamping member and the second ring groove clamping member are a row of clamping teeth.

[0013] By adopting the above technical solution, the clamping sleeve can clamp the first annular clamping groove through a row of clamping teeth, and can also clamp the second annular clamping groove through another row of clamping teeth.

[0014] Furthermore, it further includes an outer sleeve. The clamping sleeve is circumferentially provided with a plurality of vertical grooves. Each vertical groove is axially provided on the clamping sleeve, and one end of each vertical groove extends to the insertion port and forms an opening at the insertion port;

[0015] An external thread is provided on the outer wall of the clamping sleeve, and an internal thread adapted to the external thread is provided on the outer sleeve. The outer sleeve can be sleeved on the clamping sleeve and screwed through the internal thread and the external thread.

[0016] By adopting the above technical solution, the arrangement of the vertical grooves enables the diameter of the insertion port to undergo elastic deformation, facilitating the insertion of the second connecting rod into the insertion port; after the second connecting rod is clamped with the insertion port, the user can screw the outer sleeve and the clamping sleeve together, which can not only enhance the stability of the connection between the first connecting rod and the second connecting rod, but also prevent the diameter of the insertion port from expanding, making it difficult for the second connecting rod to escape from the clamping sleeve.

[0017] Furthermore, a first groove is axially formed on the rod body of the first connecting rod. One end of the first groove extends to one end of the first connecting rod and forms a first inlet opening leading to the inside of the first groove at the end of this end. A first groove clamping block adapted to the first groove is provided on the inner wall of the clamping sleeve. The first groove clamping block can pass through the first inlet opening and be inserted into the first groove and abut against the side wall extending along the length direction in the first groove;

[0018] A second groove is axially formed in the rod body of the second connecting rod. One end of the second groove extends to one end of the second connecting rod, and a second inlet block opening leading to the inside of the second groove is formed at the end of this end. A second groove clamping block adapted to the second groove is provided on the inner wall of the clamping sleeve. The second groove clamping block can pass through the second inlet block opening and be inserted into the second groove, and abut against the side wall extending along the length direction of the second groove.

[0019] By adopting the above technical solution, the first groove clamping block can abut against the side wall extending along the length direction of the first groove, so as to limit the rotation of the clamping sleeve on the first connecting rod through the cooperation of the first groove clamping block and the first groove, thereby ensuring that when the user rotates the outer sleeve, the situation that the clamping sleeve cannot be screwed into the outer sleeve due to the rotation of the clamping sleeve on the first connecting rod will not occur; the second groove clamping block can abut against the side wall extending along the length direction of the second groove, so as to limit the rotation of the clamping sleeve on the second connecting rod through the cooperation of the second groove clamping block and the second groove, thereby ensuring that when the user rotates the outer sleeve, the situation that the clamping sleeve cannot be screwed into the outer sleeve due to the rotation of the clamping sleeve on the second connecting rod will not occur.

[0020] Furthermore, a buffer member is provided on the first connecting rod. When the second connecting rod is clamped with the clamping sleeve, the buffer member is abutted between the first connecting rod and the second connecting rod.

[0021] By adopting the above technical solution, the buffer member can form a buffer between the clamping sleeves and absorb the impact force conducted between the clamping sleeves.

[0022] Furthermore, the buffer member is a buffer pad.

[0023] By adopting the above technical solution, the buffer pad can form a buffer between the clamping sleeves and absorb the impact force conducted between them, playing a role in shock absorption and sound absorption.

[0024] Furthermore, the buffer member includes a reed and a fixing bolt. Two screw interfaces are oppositely arranged on the end port of one end of the first connecting rod. Waist-shaped holes are axially formed at both ends of the reed along the length direction of the reed;

[0025] The fixing bolts correspond to the waist-shaped holes one by one, and each fixing bolt can pass through the corresponding waist-shaped hole and be screwed with the corresponding screw interface, and abut the reed between the fixing bolt and the first connecting rod.

[0026] By adopting the above technical solution, when the clamping sleeve is connected to the first connecting rod and the second connecting rod, the reed can not only deform and form a buffer between the first connecting rod and the second connecting rod, but also prevent the first connecting rod and the second connecting rod from shaking up and down in the clamping sleeve, avoiding the generation of noise caused by the up and down shaking of the first connecting rod and the second connecting rod in the clamping sleeve.

[0027] In summary, the present application includes the following beneficial technical effects:

[0028] It includes a clamping sleeve, a first connecting rod and a second connecting rod. One end of the clamping sleeve is sleeved on the first connecting rod and connected to the first connecting rod. The port at the other end of the clamping sleeve forms an insertion port. One end of the second connecting rod can be inserted into the insertion port to abut against the first connecting rod, and the second connecting rod can be clamped with the clamping sleeve. When it is necessary to connect the first connecting rod and the second connecting rod, the user can first align the second connecting rod with the insertion port, and then insert one end of the second connecting rod into the insertion port until it abuts against the end of the first connecting rod, so that the second connecting rod can be connected to the first connecting rod by clamping with the clamping sleeve, thereby realizing the rapid connection between the first connecting rod and the second connecting rod. When it is necessary to disassemble the first connecting rod and the second connecting rod, the user can directly pull out the second connecting rod from the clamping sleeve, so that the user can disassemble and assemble the first connecting rod and the second connecting rod by hand without using special tools, thus facilitating the user to disassemble and assemble the rods.

Detailed Description of the Invention

[0033] The following combines the attached Figure 1 - Attached Figure 3For further illustration:

[0034] Refer to Figure 1 and Figure 2 In the first embodiment, a connecting member for a rod provided in the present application includes: a clamping sleeve 1, an outer sleeve 4, a first connecting rod 2 and a second connecting rod 3. One end port of the clamping sleeve 1 forms an insertion port 11. Two vertical slots 12 are oppositely provided along the axial direction of the clamping sleeve 1 on the insertion port 11. One end of each vertical slot 12 is located at the insertion port 11 and forms an opening, and the other end of each vertical slot 12 extends to the middle of the clamping sleeve 1. The insertion port 11 is divided by the two vertical slots 12 into two fitting members 111 with approximately semi-circular cross-sections, and the ends of the two fitting members 111 far from the clamping sleeve 1 can approach or move away from each other, thereby changing the diameter of the insertion port 11 to facilitate the user to insert the rod into the insertion port 11.

[0035] Refer to Figure 2 and Figure 3 On the inner wall of the clamping sleeve 1, there are provided two first annular groove clamping members 15, four second annular groove clamping members 16, two first groove clamping blocks 13 and two second groove clamping blocks 14. The two first groove clamping blocks 13 are located between the two first annular groove clamping members 15 and the insertion port 11. The two second groove clamping blocks 14 are located between the two first groove clamping blocks 13 and the insertion port 11. The four second annular groove clamping members 16 are located between the two second groove clamping blocks 14 and the insertion port 11.

[0036] Refer to Figure 2 and Figure 3 On the rod body of the first connecting rod 2, two first annular clamping grooves 21 are circumferentially provided. Each first annular clamping groove 21 corresponds to a first annular groove clamping member 15, and each first annular groove clamping member 15 can be inserted into a corresponding first annular clamping groove 21 and abutted against the groove wall of the first annular clamping groove 21, so as to be able to clamp the clamping sleeve 1 and the first connecting rod 2 through the cooperation of the first annular groove clamping member 15 and the first annular clamping groove 21; on the rod body of the first connecting rod 2, two first grooves are also circumferentially and equidistantly provided. Both first grooves are provided along the length direction of the first connecting rod 2, and one end of each first groove extends to one end of the first connecting rod 2 and forms a first inlet opening leading to the inside of the first groove at the end of this end; on the inner wall of the clamping sleeve 1, two first groove clamping blocks 13 are oppositely provided along the axial direction. Each first groove corresponds to a first groove clamping block 13, and each first groove clamping block 13 can pass through a corresponding first inlet opening and be inserted into the first groove and abutted against the side wall extending along its length direction in the first groove, so as to be able to limit the relative rotation between the clamping sleeve 1 and the first connecting rod 2 through the cooperation of the first groove and the first groove clamping block 13.

[0037] Refer to Figure 2 and Figure 3, two second annular clamping grooves 31 are circumferentially formed on the rod body of the second connecting rod 3. Each second annular clamping groove 31 corresponds to two second annular groove clamping members 16. Two second groove clamping blocks 14 are provided on each fitting member 111. Each second annular groove clamping member 16 can be inserted into a corresponding second annular clamping groove 31 and abutted against the groove wall of the second annular clamping groove 31, so that the clamping sleeve 1 can be clamped with the second connecting rod 3 through the cooperation of the second annular groove clamping member 16 and the second annular clamping groove 31. Two second grooves are also circumferentially and equidistantly formed on the rod body of the second connecting rod 3. Both second grooves are formed along the length direction of the second connecting rod 3, and one end of each second groove extends to one end of the second connecting rod 3 and forms a second inlet opening leading to the inside of the second groove at the end of this end. Two second groove clamping blocks 14 are axially and oppositely provided on the inner wall of the clamping sleeve 1. One second groove clamping block 14 is provided on each fitting member 111, and the connection line of the two second groove clamping blocks 14 is perpendicular to the connection line of the two first groove clamping blocks 13. Each second groove corresponds to one second groove clamping block 14. Each second groove clamping block 14 can pass through a corresponding second inlet opening and be inserted into the second groove and abutted against the side wall extending along its length direction in the second groove, so as to be able to limit the relative rotation between the clamping sleeve 1 and the second connecting rod 3 through the cooperation of the second groove and the second groove clamping block 14.

[0038] Specifically, the first annular groove clamping member 15 can be an annular convex block or a row of clamping teeth arranged circumferentially along the inner wall of the clamping sleeve 1; the second annular groove clamping member 16 can be a semi-annular convex block or a row of clamping teeth arranged in a semi-circular shape.

[0039] See Figure 2 and Figure 3 , an external thread is provided on the outer wall of the clamping sleeve 1, an internal thread 41 adapted to the external thread is provided on the outer sleeve 4, and the outer sleeve 4 can be sleeved on the clamping sleeve 1 and screwed with the external thread through the internal thread 41, so as to not only enhance the stability of the connection between the first connecting rod 2 and the second connecting rod 3, but also prevent the diameter of the insertion port 11 from expanding, so that the second connecting rod 3 is not easily detached from the clamping sleeve 1.

[0040] The using process of a connecting member for a rod provided by this application is as follows:

[0041] When it is necessary to connect the first connecting rod 2 and the second connecting rod 3, the user can first insert the first connecting rod 2 into the end port of the clamping sleeve 1 away from the insertion port 11, so that the clamping sleeve 1 is clamped with the first connecting rod 2. Then, align the second connecting rod 3 with the insertion port 11, and insert one end of the second connecting rod 3 into the insertion port 11 until it abuts against the end of the first connecting rod 2, so that the second connecting rod 3 can be connected to the first connecting rod 2 by clamping with the clamping sleeve 1. Finally, tighten the outer sleeve 4 on the clamping sleeve 1 so that the outer sleeve 4 can wrap the insertion port 11, thereby realizing the quick connection between the first connecting rod 2 and the second connecting rod 3; when it is necessary to disassemble the first connecting rod 2 and the second connecting rod 3, the user can first unscrew the outer sleeve 4 from the insertion port 11, and then directly pull out the second connecting rod 3 from the clamping sleeve 1, so that the user can disassemble and assemble the first connecting rod 2 and the second connecting rod 3 by hand without using special tools, thus facilitating the user to disassemble and assemble the rods.

[0042] See Figure 3 , in the second embodiment, a buffer member 5 is provided on both the first connecting rod 2 and the second connecting rod 3. When the second connecting rod 3 is clamped with the clamping sleeve 1, the two buffer members 5 are abutted between the first connecting rod 2 and the second connecting rod 3. The buffer member 5 can be a buffer pad (not shown in the figure) adhered to the end of the first connecting rod 2 or the second connecting rod 3. The buffer pad can be made of rubber material to form a buffer between the first connecting rod 2 and the second connecting rod 3 and absorb the impact force conducted between the first connecting rod 2 and the second connecting rod 3.

[0043] Preferably, the buffer member 5 can also be two reed pieces 51. Waist-shaped holes are formed at both ends of each reed piece 51 along the length direction of the reed piece 51. Two screw interfaces for screwing and fixing bolts 52 are oppositely formed at the end of the first connecting rod 2. Each fixing bolt 52 can pass through a corresponding waist-shaped hole and be screwed with a corresponding screw interface, and the first reed piece 51 is abutted between the fixing bolt 52 and the first connecting rod 2; two screw interfaces for screwing and fixing bolts 52 are also formed at the end of the second connecting rod 3. The fixing bolt 52 cooperates with the screw interface to abut the second reed piece 51 between the fixing bolt 52 and the second connecting rod 3. The length direction of the first reed piece 51 is perpendicular to the length direction of the second reed piece 51. When the clamping sleeve 1 is connected to the first connecting rod 2 and the second connecting rod 3, on the one hand, the two reed pieces 51 will deform and form a buffer between the first connecting rod 2 and the second connecting rod 3; on the other hand, due to process limitations, the clamping between the first connecting rod 2 and the clamping sleeve 1 and the clamping between the second connecting rod 3 and the clamping sleeve 1 are likely to cause shaking in the axial direction of the clamping sleeve 1. The two reed pieces 51 can apply force to the first connecting rod 2 and the second connecting rod 3, so that the first annular groove clamping member 15 can abut against the groove wall on the side far from the clamping sleeve 1 in the first annular clamping groove 21, and the first annular groove clamping member 15 can also abut against the groove wall on the side far from the clamping sleeve 1 in the second annular clamping groove 31. As a result, the second connecting rod 3 and the second connecting rod 3 are not likely to shake up and down in the clamping sleeve 1, and the noise generated by the shaking of the second connecting rod 3 and the second connecting rod 3 along the axial direction of the clamping sleeve 1 in the clamping sleeve 1 is avoided.

[0044] It should be noted that if a rod connecting member is used for building an industrial guardrail or a large tent bracket, the materials of the clamping sleeve 1 and the outer sleeve 4 can be fiber-reinforced materials, such as fiber-reinforced nylon materials. This material can not only meet the use strength requirements, but also is not easy to deform and has good durability; if a rod connecting member is used for building a truss structure, the materials of the clamping sleeve 1 and the outer sleeve 4 can be metal materials, such as aluminum alloy, etc.

[0045] The working principle of a rod connecting member of the present application during use is specifically as follows:

[0046] When it is necessary to connect the first connecting rod 2 and the second connecting rod 3, the user can first insert the first connecting rod 2 into the end port of the clamping sleeve 1 away from the insertion port 11, so that the clamping sleeve 1 is clamped with the first connecting rod 2. Then, align the second connecting rod 3 with the insertion port 11, and insert one end of the second connecting rod 3 into the insertion port 11 until it abuts against the end of the first connecting rod 2, so that the second connecting rod 3 can be connected to the first connecting rod 2 by being clamped with the clamping sleeve 1. Finally, tighten the outer sleeve 4 on the clamping sleeve 1 so that the outer sleeve 4 can wrap the insertion port 11, thereby realizing the quick connection between the first connecting rod 2 and the second connecting rod 3; when it is necessary to disassemble the first connecting rod 2 and the second connecting rod 3, the user can first unscrew the outer sleeve 4 from the insertion port 11, and then directly pull out the second connecting rod 3 from the clamping sleeve 1, so that the user can disassemble and assemble the first connecting rod 2 and the second connecting rod 3 by hand without using special tools, thus facilitating the user to disassemble and assemble the rods.

[0047] It should be noted that the above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
