DETAILED DESCRIPTION

[0036] To further clarify the technical means and effects taken by the present application to achieve the predetermined purposes, the specific embodiments, structures, features and effects thereof according to the present application are described in detail below in combination with the drawings and preferred embodiments. In the following description, different "an embodiment" or "embodiments" do not necessarily refer to the same embodiment. In addition, the specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0037] The present application provides a sealing and fixing device (referred to as "fixing device" for short) for providing unilateral operation. By using the fixing device to perform unilateral operation on one side of the plate or wall, the assembly can be sealed and fixed in the mounting hole of the plate or wall, without the need for assembly operation from both sides of the plate or wall. The operation is simple, convenient to use and reliable to install.

[0038] The assembly can be a wire harness, a bearing or a sleeve, etc. In specific embodiments, the assembly is taken as an example of a wire harness to provide unilateral operation sealing and fixing for the wire harness running through the mounting hole of the plate or wall by using the fixing device.

[0039] As Figure 1As shown, the fixing device disclosed in the present application specifically comprises a fixing base 1, a deformable sealing member 2 and a locking member 3 detachably assembled with the fixing base 1. The fixing base 1 comprises a base body 11 with a receiving channel and a fixing ring groove 12 arranged around the outer side of the base body 1, and the base body 11 is provided with an adjusting slot 112 in the length direction so that the fixing ring groove 12 has a variable radial size; the deformable sealing member 2 is arranged in position in the receiving channel of the base body 11 and comprises a sealing body 21 provided with a first through hole 210 through which an assembly passes; the locking member 3 comprises an extrusion rod 31 provided with a second through hole 313 and a locking structure connected with the fixing base 1 in a locked manner, and the extrusion rod 31 is inserted into the receiving channel to extrude the sealing body 21 in the length direction, so that the sealing body 21 is deformed in the first radial direction towards the outer diameter and in the second radial direction towards the inner diameter, the first radial deformation of the sealing body 21 extrudes the inner wall of the receiving channel in the radial direction outwards to make the adjusting slot 112 smaller, so that the radial size of the base body 11 is increased, and at the same time, the second radial deformation of the sealing body 21 in the radial direction inwards makes the hole diameter of the first through hole 210 smaller, so as to seal the assembly (for example, the assembly is a wire harness) inserted into the first through hole 210.

[0040] In combination with Figure 2 , Figure 3A and Figure 3B , as shown. In order to facilitate the sealing and fixing of the assembly when one end of the fixing base 1 is inserted into the mounting hole of the plate or wall, one end of the base body 11 can be provided as an insertion end 111 with a slightly smaller size, and the base body 11 is inserted into the mounting hole from one side of the plate or wall through the insertion end 111 until the fixing ring groove 12 of the base body 11 is aligned with the groove wall of the mounting hole, and the radial size of the fixing ring groove 12 can be adjusted through the adjusting slot 112, so that the groove wall of the mounting hole is clamped into the fixing ring groove 12, and the fixing base 1 can be clamped and fixed with the mounting hole of the plate or wall by the fixing ring groove 12.

[0041] The adjusting slot 112 is mainly used to adjust the radial size at the fixing ring groove 12, and after the sealing body 21 is extruded in the length direction by the end of the extrusion rod 31, the first radial deformation of the sealing body 21 pushes the outer diameter of the base body 11 to increase, so that the adjusting slot 112 is smaller, so that the size of the fixing ring groove 12 of the fixing base 1 is adapted to the mounting hole of the plate or wall, and the fixing ring groove 12 can be clamped and fixed with the mounting hole of the plate or wall. Therefore, the adjusting slot 112 is arranged at the insertion end 111 and extends at least to the fixing ring groove 12, so that the first radial deformation of the sealing body 21 is used to reduce the adjusting slot 112, and the radial size of the fixing ring groove 12 is increased correspondingly.

[0042] In order to limit the deformable seal 2 in the containing channel of the seat body 11, a limiting cavity 13 is arranged in the containing channel, which is matched with the deformable seal 2 and has a stop wall 131 opposite the slot of the containing channel. When the extruding rod 31 is inserted into the containing channel to extrude the seal body 21 in the length direction, the stop wall 131 can stop the end face of the deformable seal 2 to make the seal body 21 radially deform.

[0043] The locking member 3 is detachably assembled with the fixing seat 1 by a locking structure, and the end of the extruding rod 31 of the locking member 3 abuts against the seal body 21 and is fixed with the locking member 3, so that the seal body 21 is maintained in a reliable radially deformed state.

[0044] In order to prevent the deformable seal 2 from rotating with the extruding rod 31 in the limiting cavity 13 during assembly and fixation, a rotation stopping groove 14 is arranged on the slot wall of the containing channel. Correspondingly, the deformable seal 2 also comprises a rotation stopping protrusion 22 arranged on the outer side of the seal body 21, and the end of the rotation stopping protrusion 22 extends into the rotation stopping groove 14 to form a radially limiting fit.

[0045] In order to put the deformable seal 2 into the limiting cavity 13 of the fixing seat 1, there are various embodiments.

[0046] For example, the radial dimension of the containing channel of the fixing seat 1 is greater than the radial dimension of the deformable seal 2, so that the deformable seal 2 can be put into from the entrance of the containing channel until it enters the limiting cavity 13 at the bottom end of the containing channel and is stopped by the stop wall 131 so that it cannot fall out from the other end of the containing channel.

[0047] The fixing seat 1 and the deformable seal 2 can be materials with different hardness or materials with the same or different hardness. Preferably, the fixing seat 1 is made of a plastic with higher hardness, and the deformable seal 2 is made of a plastic, silica gel or rubber with slightly lower hardness and better deformation ability.

[0048] As shown in Figure 4A The fixing seat 1 is formed by relatively splicing a first seat body part 101 and a second seat body part 102, and the two seat body parts 101 and 102 are connected by a flexible connecting part 103 on one same side, and one of the two seat body parts 101 and 102 is provided with a buckle 104, and the surface of the other one is provided with a plurality of holding positions 16, and the buckle 104 is connected with the holding positions 16 by buckling. In this way, the deformable seal 2 can be conveniently limited and assembled into the limiting cavity 13, and then the outer diameter of the seat body 11 is fixed by buckling the buckle 104 with the holding positions 16, so that the extruding rod 31 can extrude the deformable seal 2 in the length direction when it is inserted into the containing channel of the seat body 11.

[0049] The flexible connecting portion 103 can be made of the same material as the seat body 11, and has a small thickness so as to have excellent bending performance when connected between the first seat body portion 101 and the second seat body portion 102. Of course, the flexible connecting portion 103 can also be made of the same material as the sealing body 21 so as to have better bending performance.

[0050] Further, as shown in Figure 4B , the first seat body portion 101 and the second seat body portion 102 can be completely separated, and the same side edges of the two are respectively buckled to the buckling positions 16 provided on the surface of the other portion by a buckle 104. Alternatively, the first seat body portion 101 and the second seat body portion 102 are relatively spliced, and a limiting ring is sleeved on the outer side surface so that the outer diameter size of the seat body 11 is fixed.

[0051] As shown in Figure 4A , Figure 4B , the structure of the fixed seat 1 can be designed such that even if the radial size of the accommodating through groove is not greater than the radial size of the deformable sealing member 2, the deformable sealing member 2 can be first placed in one of the first seat body portion 101 and the second seat body portion 102, and then the other one is relatively spliced, so that the deformable sealing member 2 can be conveniently limited in the limiting cavity 13 of the accommodating through groove, and the deformable sealing member 2 cannot fall off from the accommodating through groove, thereby avoiding the influence on use caused by falling off during use.

[0052] Further combining Figure 5 and Figure 6 , the deformable sealing member 2 includes a sealing body 21 having a first through hole 210, and the two opposite end surfaces of the sealing body 21 in the length direction are respectively a pushing surface 211 and a stopping surface 212. The pushing surface 211 abuts against the extrusion rod 31 of the locking member 3, and the stopping surface 212 abuts against the stopping wall 131 in the accommodating through groove of the fixed seat 1.

[0053] When the extrusion rod 31 at the end is extruded towards the stopping wall 131 through the pushing surface 211, the sealing body 21 is radially deformed: the sealing body 21 generates a first radial deformation in the outward radial direction to expand the groove wall of the accommodating through groove in the radial outward direction, so as to make the adjusting gap 112 on the seat body 11 smaller and thus increase the radial size of the seat body 11; at the same time, the sealing body 21 also generates a second radial deformation in the inward radial direction towards the central axis of the first through hole 210, and the second radial deformation makes the inner diameter of the first through hole 210 smaller, thereby sealing the assembly passing through the first through hole 210.

[0054] In order to improve the deformation of the sealing body 21 in the radial direction, a deformation cavity 23 can be arranged in the sealing body 21, which is located between the two opposite end faces of the sealing body 21 in the length direction, i.e. between the pushing face 211 and the abutting face 212. When the pushing face 211 is pressed by the pressing rod 31 towards the abutting face 212, the pushing face 211 deforms towards the abutting face 212, and the length direction of the deformation cavity 23 between the pushing face 211 and the abutting face 212 is compressed. In the process of compression of the deformation cavity 23, a second radial deformation with a larger deformation degree can be generated towards the first through hole 210, and the outer peripheral portion of the deformation cavity 23 is extruded in the radial direction to generate a first radial deformation with a larger deformation degree.

[0055] In order to improve the sealing performance of the first through hole 210 of the sealing body 21 to the assembly, the inner diameter of the first through hole 210 should not be too large relative to the assembly. In order to facilitate the assembly to pass through the first through hole 210 of the sealing body 21, in some embodiments, as shown in Figure 7A and Figure 7B the deformable sealing member 2 includes a first sealing member 201 and a second sealing member 202 that are combined together, and a first through hole 210 for the assembly to pass through is formed between the first sealing member 201 and the second sealing member 202 when they are combined together. One side of the first sealing member 201 and the second sealing member 202 can be connected together, as shown in Figure 7A , and the first sealing member 201 and the second sealing member 202 can also be completely separated, as shown in Figure 7B .

[0056] In addition, the end of the first through hole 210 close to the abutting face 212 is provided with a flared groove 213. The flared groove 213 provides guidance for the assembly such as the wire harness, so that the wire harness is not easy to be pulled off during the process of wire pulling and turning due to the guidance provided by the flared groove 213 after passing out of the first through hole 210.

[0057] Further combining Figure 8 , Figure 9A and Figure 9B , the pressing rod 31 has an operating portion 32 at one end, and the second through hole 313 also penetrates the operating portion 32. Through the operating portion 32, the user can easily lock and fix the locking member 3 and the fixing seat 1 by using the locking structure.

[0058] The shape of the operating portion 32 is not limited, and it is only required to be convenient for the user to operate and use. For example, the operating portion 32 is cylindrical, and the outer surface is provided with a non-slip pattern.

[0059] The end face of the pressing rod 31 away from the operating portion 32 is a pressing face 311, and the pressing face 311 abuts against the pushing face 211 of the sealing body 21.

[0060] The locking member 3 can be a whole structure or can be composed of two parts, i.e., a first locking part 301 and a second locking part 302. Figure 9A As shown in FIG. 2, the two parts can be completely separable. Figure 9B As shown in FIG. 3, the two parts can be connected together.

[0061] As shown in FIG. 1 and FIG. 2, the locking member 3 is provided with a first through hole 310 and a second through hole 313. Figure 6 As shown in FIG. 1 and FIG. 2, the locking member 3 is provided with a first through hole 310 and a second through hole 313. Figure 10 As shown in FIG. 1 and FIG. 2, the locking member 3 is provided with a first through hole 310 and a second through hole 313. As shown in FIG. 1 and FIG. 2, the locking member 3 is provided with a first through hole 310 and a second through hole 313.

[0062] When the extrusion rod 31 generates an extrusion force F0 towards the sealing body 21, the pushing surface 211 of the sealing body 21 is in abutment with the extrusion surface 311, and the pushing surface 211 decomposes the extrusion force F0 into a first extrusion component F1 along the pushing surface 211 towards the radial outside of the sealing body 21 and a second extrusion component F2 perpendicular to the pushing surface 211 towards the radial inside of the sealing body 21. The first extrusion component F1 causes the outer circumferential part of the sealing body 21 to generate a first radial deformation towards the radial outside, so as to increase the radial dimension of the fixing ring groove 12 of the fixing seat 1. The second extrusion component F2 causes the inner diameter part of the sealing body 21 to generate a second radial deformation towards the inner diameter, so as to reduce the hole diameter of the first through hole 210, and thus the hole wall of the first through hole 210 firmly seals and fixes the assembly passing therethrough.

[0063] It can be understood that the hole diameter r2 of the second through hole 313 can be smaller than r1, as long as the extrusion rod 31 can generate an insertion direction extrusion force on the sealing body 21 through the extrusion surface 311 when inserted into the accommodating through groove of the seat body 11, so that the sealing body 21 is deformed by extrusion.

[0064] In addition, the locking structure has many implementation forms, such as a buckling structure or a threaded structure. A buckle is provided on the locking member 3, and the buckle is buckled with a buckling site provided on the fixing seat 1.

[0065] In the embodiment shown in the drawings, the locking structure includes an outer thread 312 provided on the outer side surface of the extrusion rod 31 and an inner thread 15 provided on the groove wall of the accommodating through groove of the seat body 11. The locking member 3 is fixed by screwing the outer thread 312 with the inner thread 15 of the seat body 11.

[0066] The accommodating through groove of the seat body 11 is shaped to match the extrusion rod 31, and the extrusion rod 31 can be cylindrical or frustoconical.

[0067] Further in combination Figures 11-13 As shown, the sealing fixing of the wire harness 8 through the plate 9 is provided by using the fixing device of the present application to perform a one-side assembly operation. It can be understood that the mounting hole is a through hole formed in the plate 9, and the wire harness 8 needs to pass through the mounting hole from one side of the plate 9 to the other side.

[0068] The wire harness 8 wiring fixing operation is as follows: first, the wire harness 8 is passed into the receiving through slot of the seat body 11, and further passed through the first through hole 210 of the deformable sealing element 2 and then passed out from the insertion end 111 of the seat body 11; then, the outer diameter size of the insertion end 111 of the fixing seat 1 is appropriately adjusted, the insertion end 111 of the fixing seat 1 is inserted from one side of the plate 9 to the mounting hole of the plate 9, until the fixing ring groove 12 of the fixing seat 1 is just clamped into the mounting hole of the plate 9, as shown in Figure 12 Finally, the extrusion rod 31 of the locking element 3 is inserted into the receiving through slot of the seat body 11, and then the outer thread 312 of the extrusion rod 31 is screwed with the inner thread 15 of the inner wall of the receiving through slot, as the extrusion rod 31 is screwed into the receiving through slot, the extrusion surface 311 of the extrusion rod 31 abuts against the pushing surface 211 of the deformable sealing element 2, and the pushing surface 211 generates an extrusion force on the deformable sealing element 2, which causes the sealing body 21 to generate a first radial deformation in the outer diameter direction and a second radial deformation in the inner diameter direction. The first radial deformation generates a radial outward extrusion force on the inner wall of the receiving through slot, which makes the adjusting gap 112 smaller, thereby increasing the radial size of the seat body 11 and increasing the outer diameter of the fixing ring groove 12 to match the inner diameter of the mounting hole of the plate 9, so that the fixing seat 1 is clamped and fixed in the mounting hole of the plate 9 through the fixing ring groove 12; the second radial deformation of the sealing body 21 in the radial direction makes the hole diameter of the first through hole 210 smaller, thereby sealing the wire harness 8 passing through the first through hole 210.

[0069] During the entire operation process, whether the insertion end 111 of the fixing seat 1 is inserted into the mounting hole of the plate 9 or the subsequent operation of the locking element 3 cooperating with the fixing seat 1 to generate an extrusion force on the deformable sealing element 2, it is a one-side operation on the same side of the plate 9, thereby facilitating the user's operation and use.

[0070] Furthermore, after the locking element 3 is locked with the fixing seat 1 through the locking structure, the locking element 3 will not be unlocked relative to the fixing seat 1 without external force, so that the fixing device of the present application can reliably seal and fix the wire harness wiring.

[0071] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
