DETAILED DESCRIPTION

[0033] The utility model is further described below in conjunction with the accompanying drawings.

[0034] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0035] like Figure 1-6 As shown, the utility model provides a clamp structure.

[0036] The clamp structure includes a first arc-shaped clamp 7 and a second arc-shaped clamp 3. The first end of the first arc-shaped clamp 7 and the first end of the second arc-shaped clamp 3 are hinged. The second end of the first arc-shaped clamp 7 and the second end of the second arc-shaped clamp 3 are detachably connected through a locking structure. The second end of the first arc-shaped clamp 7 and the second end of the second arc-shaped clamp 3 are opened and closed to fix the pipe 6.

[0037] In the present application, the locking structure includes a spring clamping groove 71, a special-shaped spring 1 and a spring wrench 2, the spring wrench 2 includes a fixed end and a movable end, the special-shaped spring 1 includes a connecting end 13 and a mating end 11, the connecting end 13 and the mating end 11 are connected by an elastic arm 12, the fixed end of the spring wrench 2 is hinged to the second end of the second arc-shaped clamp 3, the movable end of the spring wrench 2 and the connecting end 13 of the special-shaped spring 1 are hinged, and the spring clamping groove is arranged at the second end of the first arc-shaped clamp 7; the spring clamping groove 71, the special-shaped spring 1 and the spring wrench 2 are combined to form a spring buckle structure, and the spring buckle structure formed by the spring clamping groove 71, the special-shaped spring 1 and the spring wrench 2 can realize the rapid opening and closing of the clamp.

[0038] The outer surface of the second arc-shaped clamping plate 3 is provided with a wrench hidden groove 32 and a spring hidden groove 31. When the mating end 11 of the special-shaped spring 1 is matched with the spring clamping groove 71 and the spring wrench 2 abuts against the wrench hidden groove 32, the clamp is in a self-locking state;

[0039] The movable end of the spring wrench 2 extends to a side away from the fixed end to form a pressing portion 21. When the clamp is in a self-locking state, the special-shaped spring 1 abuts against the spring hidden groove 31, and the pressing portion 21 is located on the side of the spring wrench 2 away from the spring clamping groove 71. Combined with the aforementioned extension of the movable end of the spring wrench 2 to a side away from the fixed end to form the pressing portion 21, it can be obtained that when the clamp is in a self-locking state, the movable end of the spring wrench 2 is located on the side of the fixed end away from the spring clamping groove 71, and only the pressing portion 21 of the spring wrench 2 is higher than the outer surface of the second arc-shaped clamping plate 3 with the largest radius;

[0040] By pushing the pressing portion 21 in the reverse assembly direction, the spring wrench 2 can be rotated, thereby releasing the engagement between the engagement end of the special-shaped spring 1 and the spring clamping groove 71 .

[0041] In this embodiment, the special-shaped spring 1 is formed by bending a metal rod body in one piece, and has two bent rods and a buckle rod. The two bent rods are arranged in parallel as elastic arms 12, and the ends of the two bent rods are bent to one side to form a connecting end 13, and the buckle rod connects the head ends of the two bent rods to form a matching end 11. The two bent rods are arranged in parallel as elastic arms 12. When the clamp is in a self-locking state, the two bent rods abut in the spring hidden groove 31; the ends of the two bent rods are bent to one side to form a connecting end 13 to be hinged with the spring wrench 2; the buckle rod is used as a matching end 11 to connect the head ends of the two bent rods to match the spring clamp groove 71. Since the special-shaped spring 1 here is formed by bending a metal rod body in one piece, the spring hidden groove 31 corresponding to the two bent rods is more convenient to process during implementation and occupies less space.

[0042] In this embodiment, each bent rod end is bent toward the direction close to the other bent rod to form a connecting end 13, and the spring hidden groove 31 is provided on both sides of the axial direction of the second arc clamping plate 3. Each bent rod end is bent toward the direction close to the other bent rod. In this way, the two bent rods are at the most side positions in the width of the special-shaped spring 1; in combination with this, the spring hidden groove 31 is provided on both sides of the axial direction of the second arc clamping plate 3, which makes real-time processing more convenient.

[0043] In this embodiment, the two end surfaces of the pressing part 21 of the spring wrench 2 are provided with insertion holes 211 for the connection end 13 of the special-shaped spring 1 to be hinged. The connection end 13 of the special-shaped spring 1 is hinged on the pressing part 21 of the spring wrench 2. Specifically, the two end surfaces of the pressing part 21 are provided with insertion holes 211, so as to facilitate the driving of the spring wrench 2 as a whole when the pressing part 21 is applied with force.

[0044] Furthermore, the insertion holes 211 on both end surfaces of the pressing portion 21 are connected, which is convenient for processing, and one-time processing can ensure that the insertion holes 211 on both end surfaces are coaxially arranged.

[0045] In this embodiment, the fixed end of the spring wrench 2 is hinged in the wrench hidden groove 32 at the second end of the second arc-shaped clamping plate 3 through the first pin 41. The fixed end of the spring wrench 2 and the wrench hidden groove 32 have corresponding openings for the first pin 41 to connect to realize the hinge connection between the two, and the structure is simple.

[0046] In this embodiment, a groove or a bump is formed at the first end of the first arc-shaped clamping plate 7 , and a bump or a groove is correspondingly provided at the first end of the second arc-shaped clamping plate 3 . The first end of the first arc-shaped clamping plate 7 and the first end of the second arc-shaped clamping plate 3 are connected by a second pin 42 .

[0047] In this embodiment, the first end of the first arc-shaped clamping plate 7 and the first end of the second arc-shaped clamping plate 3 are respectively formed with grooves or protrusions to achieve a snap-fit ​​connection between the two, and then the first end of the first arc-shaped clamping plate 7 and the first end of the second arc-shaped clamping plate 3 are connected by the second pin 42. The connection structure is simple and avoids exposure of the connecting parts, thereby improving the overall integrity.

[0048] In the present embodiment, the first arc-shaped splint 7 and the second arc-shaped splint 3 are both semicircular splints. Preferably, the first arc-shaped splint 7 and the second arc-shaped splint 3 are both semicircular splints, and only the first arc-shaped splint 7 and the second arc-shaped splint 3 are needed to realize the opening and closing of the clamp. Obviously, in some embodiments, the arc-shaped splint is not limited to a semicircular shape, for example, the first arc-shaped splint 7 is a quarter circle, and the second arc-shaped splint 3 is a three-quarter circle. The second arc-shaped splint 3 includes two parts, a semicircular splint and a quarter-circular splint, which are interconnected. The quarter-circular splint is hinged on the semicircular splint as the second end of the second arc-shaped splint 3, and the end of the semicircular splint away from the quarter-circular splint serves as the first end of the second arc-shaped splint 3.

[0049] In this embodiment, both axial sides of the first arc-shaped clamping plate 7 and the second arc-shaped clamping plate 3 extend inward to form a limiting portion 5, so as to facilitate the matching and limiting of the joint surface of the fixed pipe 6.

[0050] In this embodiment, after the pressing portion 21 is in place, the contact position between the special-shaped spring 12 and the spring clamping groove 71 is used as the rotation point. Specifically, in this application, the axial position of the mating end 11 of the special-shaped spring 12 is used. The straight line from the rotation point to the pressing portion 21 of the spring wrench 2 is the force arm. The force arm is below the surface of the clamp. The elastic force of the contraction of the special-shaped spring 1 tightly pulls the spring wrench 2. At this time, the clamp is in a self-locking state. Compared with the existing clamp, the clamp structure in this application is specially designed with a wrench hidden groove 32 and a spring hidden groove 31. Therefore, after the clamp structure is self-locked, the locking structure protrudes less from the outer surface of the clamp, reducing the risk of damage to the locking structure due to interference, and the entire clamp is closer to a cylinder and more beautiful. In addition, during the closing process, when the spring wrench 2 is in place, it collides with the surface of the clamp, producing a "click" sound, which not only brings a more comfortable acoustic experience to the user, but also serves to remind the user that the closure is in place.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
