Preferably, the groove shape of the accommodating groove provided on the opposite side of the first sealing member 103 and the second sealing member 104 matches the outer circumference or pipe diameter of the wire harness 102, thereby further improving the sealing performance of the sealer. In order to raise the tightness of the threading hole 1001 as high as possible without any influence on the wire harness 102 itself, the first sealing member 103 and the second sealing member 104 are abutted by providing the first sealing member 103 in the form of including the first fixing member 1031 and the first sealing block 1032, and the second sealing member 104 in the form of including the second fixing member 1041 and the second sealing member 104, and at the same time, the first fixing member 1031 and the second fixing member 1041 are abutted. Corresponding grooves are provided at the mating sides of the first and second fixtures 1031 and 1041, respectively, and corresponding grooves are provided at the mating sides of the first and second seal blocks 1032 and 1042, respectively, and as shown in fig. 1, the grooves provided at the fixtures and the grooves provided at the seal blocks communicate in the axial direction of the wire harness 102. The mode of setting simultaneously is that bottom plate 100 is down, then sealed piece, then the mounting, in order to further improvement sealing performance, so fix the sealed piece between the two through the fixed form of mounting and bottom plate 100 to impel it to seal the through wires hole 1001 who sets up on bottom plate 100 when hugging closely pencil 102, especially in abominable engineering environment, can effectively improve air and the comfort level in the driver's cabin, thereby avoid factors such as dust to cause the uncomfortable of operator, or cause interference or damage to the precision instruments in the driver's cabin.

First, the two fixing members and the two sealing blocks may be the sealing blocks that tightly embrace the wire harness 102 and seal the threading hole 1001, and the fixing members only serve to fix and press the sealing blocks. Alternatively, the sealing block and the fixing member may jointly embrace the wire harness 102 and seal the threading hole 1001, and the fixing member also plays a role of fixing and compressing the sealing block. This embodiment is not particularly limited thereto.

Secondly, the shape of the accommodating groove can be adaptive to the wire harness 102, or the sealing block can be pressed tightly by the fixing piece to deform the wire harness 102 adaptively, so as to complete the functions of holding and sealing. This embodiment is not particularly limited thereto.

Third, in this embodiment, the material, shape, etc. of the sealing block and the fixing element are not specifically limited, and may be, for example, square, circular, etc., as long as both of them can perform corresponding functions.

Fourth, the fixing form of the fixing member and the bottom plate 100 in this embodiment is not particularly limited, and may be, for example, an adhesive, or may be fastened by a fastening member in the subsequent embodiments. Meanwhile, in order to further fix the sealing block, other fixing measures for fixing the sealing block can be added.

Fifth, whether the first fixing member 1031 and the second fixing member 1041 are symmetrically arranged through the wire harness 102 is not specifically limited in the present application, for example, as shown in fig. 1, the first fixing member 1031 and the second fixing member 1041 are symmetrically arranged (that is, the first fixing member 1031 and the second fixing member 1041 are completely symmetrical), or the first fixing member 1031 is larger, a groove body arranged thereon is also larger, the second fixing member 1041 is smaller, and the groove body arranged thereon is also smaller, and the two are aligned together. And the same applies to the first sealing block 1032 and the second sealing block 1042. The following third fixing element 1033 and fourth fixing element 1043 are also the same, and this application does not specifically limit them.

Optionally, in the involution state of the first sealing element 103 and the second sealing element 104, a distance a between two groove bottoms of the first fixing element and the second fixing element is greater than a distance b between two groove bottoms of the first sealing block and the second sealing block.

For example, in order to prevent the first fixing part 1031 and the second fixing part 1041 from being tightly combined with the wire harness 102 after the first sealing member 103 and the second sealing member 104 are combined, so that the wire harness 102 is interfered or damaged by the first fixing part 1031 and the second fixing part 1041, as shown in fig. 2, a distance a between two groove bottoms of the first fixing part and the second fixing part is set to be greater than a distance between two groove bottoms of the first sealing block 1032 and the second sealing block 1042, thereby achieving that the wire harness 102 is tightly embraced by the first sealing block 1032 and the second sealing block 1042 without directly contacting with the first fixing part 1031 and the second fixing part 1041, and further improving the protection capability of the wire harness 102 on the premise of achieving effective sealing performance. Meanwhile, fixing pieces with the same size can be used conveniently to fix the pipe diameters or diameters of the wire harnesses 102 with different sizes, and the problem of sealing performance can be solved only by replacing different sealing blocks.

First, the distance a between the two bottoms of the first fixing member and the second fixing member is the distance between the bottom ends of the tank bodies respectively disposed on the first fixing member 1031 and the second fixing member 1041, that is, the farthest distance between the bottom walls of the tank bodies (as shown in fig. 2).

Secondly, the distance b between the two groove bottoms of the first sealing block and the second sealing block is the distance between the bottom ends of the grooves respectively arranged on the first sealing block 1032 and the second sealing block 1042, i.e. the farthest distance between the bottom walls of the two grooves (as shown in fig. 2).

Optionally, the sealer further includes a fastener, and the first fixing member 1031 and the second fixing member 1041 are respectively provided with an insertion hole, and the fastener penetrates through the insertion holes to respectively fasten the first fixing member 1031 and the second fixing member 1041 to the base plate 100.

For example, in order to ensure the stability of the first fixing member 1031 and the second fixing member 1041 fixed on the base plate 100 and ensure the effective sealing performance of the first sealing block 1032 and the second sealing block 1042 at all times, insertion holes are respectively formed in the first fixing member 1031 and the second fixing member 1041, and a fastener is inserted through the insertion holes to fasten the first fixing member 1031 and the second fixing member 1041 on the base plate 100 respectively. Meanwhile, due to the mode of independently using the fastening piece, the detachable mode can be realized, and the convenience of installation and removal is further improved.

It should be noted that, first, the number of the insertion holes arranged on the first fixing member 1031 and the second fixing member 1041 may be three, four, five, and so on, and the distribution manner may be, as shown in fig. 2, uniformly distributed on the first fixing member 1031 and the second fixing member 1041, or randomly arranged, which is not specifically limited in this application.

Secondly, the above-mentioned fastener may be the bolt 105 in the following embodiments, and may also be a plurality of forms such as a clamping strip.

Optionally, the fastener is a bolt 105.

For example, as shown in fig. 3, the fastening member may be a bolt 105, so as to further reduce the manufacturing cost, and the bolt 105 fastening itself has higher stability and the manufacturing process thereof is more mature. The generalizability of the sealer in the application is further improved.

Optionally, the first sealing member 103 further includes a third fixing member 1033 disposed between the first sealing block 1032 and the bottom plate 100, and the third fixing member 1033 is fixedly connected to the first fixing member 1031 to clamp the first sealing block 1032; the second sealing member 104 further includes a fourth fixing member 1043 disposed between the second sealing block 1042 and the bottom plate 100, and the fourth fixing member 1043 is fixedly connected to the second fixing member 1041 to clamp the second sealing block 1042.

For example, as shown in fig. 3, a third fixing member 1033 is further disposed between the first sealing block 1032 and the bottom plate 100, and a fourth fixing member 1043 is further disposed between the second sealing block 1042 and the bottom plate 100, wherein in order to further cooperate and fix the sealing blocks and simultaneously play a good supporting role for the sealing blocks, a preferable solution is that the third fixing member 1033 and the fourth fixing member 1043 are disposed in an involutory manner, and a groove body is disposed on an involutory side. Meanwhile, the third fixing member 1033 and the first fixing member 1031 are arranged, and the fourth fixing member 1043 and the second fixing member 1041 are respectively matched to clamp the first sealing block 1032 and the second sealing block 1042, so that the stability of the first sealing block 1032 and the second sealing block 1042 in the clamping process is improved, and meanwhile, the stability of the sealing performance of the sealing blocks can be further ensured.

It should be noted that, when the first fixing member 1031 is fixed on the bottom plate 100, for example, a fastening member is used, the fastening member may be a fastening member that directly fixes the first fixing member 1031 on the bottom plate 100 and indirectly fixes the third fixing member 1033 by pressing the third fixing member 1033 by the first fixing member 1031, or a fastening member that respectively passes through the first fixing member 1031 and the third fixing member 1033 to more stably fix both the first fixing member 1031 and the third fixing member 1033 on the bottom plate 100 (as shown in fig. 3), or different fastening members that respectively fix both the first fixing member 1031 and the third fixing member 1033 on the bottom plate 100, and other fixing forms are not limited in this application. The second fixing element 1041 and the fourth fixing element 1043 are similar in structure, and therefore, detailed description is omitted.

Optionally, a protrusion 106 facing the bottom plate 100 is formed on the third fixing member 1033 near the involution side, so as to form a chamber for accommodating the first sealing block 1032 between the first fixing member 1031 and the third fixing member 1033; a protrusion 106 facing the bottom plate 100 is formed on the fourth fixing member 1043 near the involution side, so as to form a cavity between the second fixing member 1041 and the fourth fixing member 1043 for accommodating the second sealing block 1042; the chamber has an opening facing the apposition side.

Illustratively, as shown in fig. 3, the protrusions 106 are formed at the positions of the third fixing member 1033 and the fourth fixing member 1043 close to the involution side, so that a chamber for accommodating the first sealing block 1032 and the second sealing block 1042 is formed between the first fixing member 1031 and the third fixing member 1033, and between the second fixing member 1041 and the fourth fixing member 1043, respectively. That is, the opening of the chamber formed between the first holder 1031 and the third holder 1033 faces the direction of the wire harness 102, and the opening of the chamber formed between the second holder 1041 and the fourth holder 1043 faces the direction of the wire harness 102. The protrusion 106 is disposed in a manner that after the upper and lower layers of fixing members are fixed, because the side away from the opening is in a closed state after the upper and lower layers of fixing members are fixed, the first sealing block 1032 and the second sealing block 1042 are urged to approach the wire harness 102, and finally the wire harness 102 is tightly embraced, so that the sealing performance of the first sealing block 1032 and the second sealing block 1042 is effectively ensured.

It should be noted that, in order to further improve the sealing capability of the first sealing block 1032 and the second sealing block 1042, after the first fixing member 1031 and the third fixing member 1033, and the second fixing member 1041 and the fourth fixing member 1043 are fixed up and down, since the side far away from the chamber opening is in a sealed state, stable sealing is realized under the pushing of the chamber sidewall, and the first fixing member 1031 and the second fixing member 1041 may also be provided with corresponding protrusions 106 far away from the direction of the bottom plate 100.

Optionally, the protrusion 106 is correspondingly engaged with the threading hole 1001 of the base plate 100.

For example, as shown in fig. 3, the protrusion 106 is correspondingly clamped in the threading hole 1001 of the bottom plate 100, that is, the protrusion 106 located on the third fixing member 1033 and the fourth fixing member 1043 adapts to the shape of the threading hole 1001 of the bottom plate 100 after the two are closed, and is correspondingly clamped in the threading hole 1001, so that the first positioning function can be performed in the subsequent installation of the first sealing block 1032, the second sealing block 1042, the first fixing member 1031, and the second fixing member 1041, and meanwhile, the stability of the sealer and the bottom plate 100 in the present application is further improved, so that the damage caused by collision between the sealer and the bottom plate 100 during vibration or displacement is prevented. It should be noted that, the protrusion 106 is preferably matched with the wall thickness of the threading hole 1001, so that the threading hole 1001 can be filled as far as possible without affecting the operation of other components.

Optionally, in a fixed state of the first fixing member 1031 and the third fixing member 1033, a distance d between the first fixing member and the third fixing member is smaller than a natural thickness c of the first sealing block; when the second fixing member 1041 and the fourth fixing member 1043 are in a fixed state, a distance between the second fixing member 1041 and the fourth fixing member 1043 is smaller than a natural thickness of the second sealing block 1042.

In the example, for further improvement of the holding of the first sealing block 1032 and the second sealing block 1042 to the wire harness 102 and the sealing performance of the threading hole 1001, the application range of the sealer in the present application is simultaneously improved, and for different wire harnesses 102 with similar sizes, the two sealing blocks are deformed by squeezing the sealing blocks between the upper and lower layers of fixing members under the condition that the fixing members and the sealing blocks are not replaced, so that the wire harness 102 is held tightly and the threading hole 1001 is sealed at the same time. As shown in fig. 4, in order to ensure the above feasibility, it is necessary to ensure that the first fixing member 1031 and the third fixing member 1033 are in the fixed state.

It should be noted that, firstly, the first fixing member 1031 and the third fixing member 1033 are completely fixed together in the fixing state, and only one opening facing the wiring harness 102 is formed in the chamber (as shown in fig. 4). The second fixing element 1041 and the fourth fixing element 1043 are similar in structure, and therefore not described in detail.

Second, the distance d between the first fixing member and the third fixing member is the maximum distance between the closest side walls of the first fixing member 1031 and the third fixing member 1033 after the first fixing member and the third fixing member are fixed, that is, as shown in fig. 4. The second fixing element 1041 and the fourth fixing element 1043 are similar in structure, and therefore not described in detail.

Third, the natural thickness c of the above-described first seal block is a thickness of the first seal block 1032 in the direction of the openings of both ends of the slot body through which the wire harness 102 passes in an original state without being pressed or compressed, as shown in fig. 4. The second sealing block 1042 has the same structure, and therefore, will not be described in detail.

Optionally, the first sealing block 1032 and the second sealing block 1042 are both rubber blocks.

For example, in order to further reduce the manufacturing cost of the sealer in the present application, the materials of the first sealing block 1032 and the second sealing block 1042 may be selected to be rubber blocks. It has elastic deformation and also has the advantages of wear resistance and the like.
