DETAILED DESCRIPTION

[0030] The following descriptions of the embodiments refer to the attached drawings to illustrate specific embodiments that can be used to implement the present invention.

[0031] The utility model provides a pipe clamp for fixing a wire harness with a corrugated pipe, and its structure is as follows Figure 1 and Figure 2 As shown, the pipe clamp body 1 includes a fixed half pipe clamp 11, a movable half pipe clamp 12 and a plurality of clamp rings 13 distributed along the central axis of the pipe clamp body 1, wherein the clamp ring 13 includes a plurality of clamp ring segments 131 respectively fixedly distributed on the fixed half pipe clamp 11 and the movable half pipe clamp 12. Specifically, the pipe clamp body 1 is formed by one-time injection molding.

[0032] Compared with the prior art, the utility model provides a wire harness fixing pipe clamp with a corrugated tube. When in use, multiple clamping rings 13 can be clamped into different grooves on the surface of the corrugated tube to clamp and position the corrugated tube radially and axially, thereby fixing the wire harness with the corrugated tube.

[0033] In order to facilitate demoulding after injection molding, according to an embodiment of the utility model, the clamping ring segments 131 of adjacent clamping rings 13 are staggered.

[0034] Please continue to refer to Figure 1 or Figure 2 According to an embodiment of the utility model, the pipe clamp body 1 further includes a flexible connection belt 14 and a pipe clamp locking structure 15, wherein one end of the fixed half pipe clamp 11 is fixedly connected to one end of the movable half pipe clamp 12 through the flexible connection belt 14; the pipe clamp locking structure 15 is used to lock the fixed half pipe clamp 11 and the movable half pipe clamp 12 in a closed state after closing. In order to facilitate production and processing, the fixed half pipe clamp 11, the movable half pipe clamp 12, the clamp ring 13, the flexible connection belt 14 and the pipe clamp locking structure 15 are processed by a one-time injection molding process.

[0035] Specifically, the pipe clamp locking structure 15 includes a toothed belt 151, a stop arm 152 and a reverse latch tooth 153, wherein the toothed belt 151 is fixedly arranged on the end of the movable half-pipe clamp 12 away from the fixed half-pipe clamp 11; the stop arm 152 is fixedly arranged on the outer side of the end of the fixed half-pipe clamp 11 away from the movable half-pipe clamp 12, and is fixedly connected to the fixed half-pipe clamp 11; a slot 150 for inserting the toothed belt 151 is formed between the stop arm 152 and the fixed half-pipe clamp 11; the reverse latch tooth 153 is fixedly arranged on the surface of the stop arm 152 close to the fixed half-pipe clamp 11.

[0036] It can be understood that the toothed belt 151 is engaged with the reverse latch teeth 153, so as to maintain the fixed half-tube clamp 11 and the movable half-tube clamp 12 in a closed state; and by adjusting the depth of the toothed belt 151 inserted into the slot 150, so that different positions of the toothed belt 151 are engaged with the reverse latch teeth 153, the tightening range can be adjusted according to the outer diameter size of the wire harness, and the versatility is strong.

[0037] In order to facilitate the insertion of the toothed belt 151 into the slot 150, or to pull the toothed belt 151 in the engaged and locked state out of the slot 150 so that the pipe clamp body 1 can be released from the locked state, according to an embodiment of the utility model, the pipe clamp locking structure 15 also includes a first hand-held push plate 154 and a second hand-held push plate 155, wherein the first hand-held push plate 154 is fixedly arranged at one end of the toothed belt 151 close to the movable half-pipe clamp 12; the second hand-held push plate 155 is fixedly arranged at one end of the barrier arm 152 close to the fixed half-pipe clamp 11.

[0038] It can be understood that by providing the first hand-held push plate 154 and the second hand-held push plate 155 , the convenience of operating the pipe clamp body 1 is improved.

[0039] In order to prevent the toothed belt 151 from shaking relative to the reverse clamping teeth 153 in the axial direction and disengaging from the reverse clamping teeth 153, according to an embodiment of the utility model, the pipe clamp locking structure 15 further includes a plurality of anti-loosening ears 156, and the two ends of the anti-loosening ears 156 are respectively fixedly connected to the blocking arm 152 and the fixed half pipe clamp 11. As a specific embodiment, the plurality of anti-loosening ears 156 are distributed on both sides of the slot 150.

[0040] It can be understood that the anti-loosening ear 156 can block the toothed belt 151 from the axial direction of the pipe clamp body 1 to prevent the toothed belt 151 from moving axially relative to the reverse latch tooth 153 and disengaging from the reverse latch tooth 153, thereby improving the reliability and stability of the fixed half-pipe clamp 11 and the movable half-pipe clamp 12 in the closed state.

[0041] Since one end of the blocking arm 152 is fixedly connected to the end of the fixed half-pipe clamp 11 away from the movable half-pipe clamp 12, the other end of the blocking arm 152 is a suspended end, which will affect the rigidity of the blocking arm 152. In order to prevent the toothed belt 151 from disengaging from the reverse latch tooth 153 due to the small rigidity of the blocking arm 152, according to one embodiment of the utility model, at least one anti-loosening ear 156 is arranged at the open end of the slot 150 to limit the opening size of the slot 150 to ensure the stability of the engagement between the toothed belt 151 and the reverse latch tooth 153.

[0042] In order to prevent the toothed belt 151 from being inserted too deeply into the slot 150, which would cause the flexible connecting belt 14 to be subjected to a large tensile force and break, according to an embodiment of the utility model, a limiting hole 110 is provided at one end of the fixed half-pipe clamp 11 close to the flexible connecting belt 14, and the pipe clamp body 1 also includes a limiting block 16 fixed on one end of the movable half-pipe clamp 12 close to the flexible connecting belt 14, and the shape of the limiting block 16 matches the shape of the limiting hole 110.

[0043] It can be understood that the limit block 16 and the limit hole 110 cooperate with each other to limit the insertion depth of the toothed belt 151 in the slot 150, so as to limit the minimum tightening range of the pipe clamp body 1, thereby preventing the flexible connecting belt 14 from being broken due to a large tensile force.

[0044] In order to be able to fix the pipe clamp body 1 on the vehicle body, according to an embodiment of the utility model, the pipe clamp for fixing the wire harness with a corrugated tube also includes a vehicle body connection structure 2 fixed on the fixed half-pipe clamp 11. Specifically, the vehicle body connection structure 2 is a quick-insert structure or a snap-on structure. It should be noted that in addition to the quick-insert structure or the snap-on structure, the vehicle body connection structure 2 can also be other structures, as long as the pipe clamp body 1 can be fixed on the vehicle body. In actual situations, the vehicle body connection structure 2 can be specifically set according to the vehicle body structure. For example, when a sheet metal hole is opened on the vehicle body, the vehicle body connection structure 2 can be a snap-on structure that matches the sheet metal hole.

[0045] In summary, when the pipe clamp for fixing a wire harness with a corrugated tube provided by the utility model is in use, the multiple clamping rings 13 can be clamped into different grooves on the surface of the corrugated tube to clamp and position the corrugated tube radially and axially, thereby fixing the wire harness with the corrugated tube; by providing the first hand-held push plate 154 and the second hand-held push plate 155, the fixed half-pipe clamp 11 and the movable half-pipe clamp 12 can be locked in a closed state and released from the closed state through the pipe clamp locking structure 15, thereby improving the convenience of operating the pipe clamp body 1.

[0046] It should be noted that although the present invention is disclosed as above with specific embodiments, the above embodiments are not intended to limit the present invention. Ordinary technicians in this field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
