As shown in fig. 1 to 8, the present embodiment provides a split type housing including a first housing 100, a second housing 200 and a decorative housing 300, wherein the first housing 100 and the second housing 200 are connected and fixed together by an auxiliary module 400 for assembly.
Wherein the rib plate 101 is provided on the first housing 100, the mounting hole 201 is provided on the second housing 200, and the auxiliary module 400 for assembly is used to connect the first housing 100 and the second housing 200 to be connected together.
The auxiliary module for assembly includes: the expansion device comprises a mounting seat 1, an expansion part 2 and bolts 3, wherein two sides of the mounting seat 1 are provided with fixed limiting parts 11; the expansion member 2 has an installation portion 21 and two expansion portions 22 provided on the installation portion 21, a threaded through hole (not shown) is provided on the installation portion 21, the two expansion portions 22 are arranged opposite to each other, the threaded through hole is located between the two expansion portions 22, the installation portion 21 is provided on the installation seat, and the expansion member 2 is located between the two fixed limiting portions; the bolt 3 is in threaded connection in the threaded through hole;
wherein the rib plate 101 is positioned between the fixed limiting part 11 and the expansion part 22 which are oppositely arranged, and the bolt 3 passes through the mounting hole 201; when the bolt 3 is screwed down, the bolt 3 is inserted between the two expansion portions 22, and the rib plate 101 is clamped between the corresponding side fixing stopper portion 11 and the expansion portion 22.
In the actual use process, when the first casing 100 and the second casing 200 need to be connected and assembled, the bolt 3 is first inserted into the mounting hole 201 formed on the second casing 200, and then the threaded portion of the bolt 3 is screwed into the threaded through hole on the mounting portion 21; inserting the rib plate 101 formed on the first housing 100 into the clamping space formed by the fixed limit part 11 and the expansion part 22; finally, the bolts 3 are tightened to complete the assembly.
While in the process of tightening the bolt 3, the bolt 3 is turned in the threaded through hole, and the end of the bolt 3 is inserted between the two expansion portions 22. In the process of inserting the bolt 3 between the two expansion parts 22, the expansion parts 22 at the two sides expand towards the two sides under the action of the bolt 3, so that the expansion parts 22 move towards the fixed limiting part 11. In this way, during the tightening of the screw 3, the second housing 200 is brought into close contact with the mounting base 1, and the rib 101 is clamped between the fixing and limiting portion 11 and the expansion portion 22, so that the first housing 100 and the second housing 200 are reliably connected together.
In the assembly process, after the first housing 100 and the second housing 200 are coupled together, the mounting holes 201 are shielded by the decorative case 300 in order that the entire appearance does not expose the mounting holes 201 and the bolts since the mounting holes 201 on the second housing 200 can be seen from the housing after the first housing 100 and the second housing 200 are fixedly coupled together.
Wherein, for the connection process between the decorative case 300 and the second case 200, specifically: the decoration shell 300 is installed and fixed on the second housing 200 in a clamping manner, and the installation hole 201 is shielded by the decoration shell 300, so that the installation hole 201 can not be seen by the housing assembly outside, and the appearance effect of the whole bolt-free exposure is achieved.
In some embodiments, for the interface region between the decorative shell 300 and the first housing 100, the edge of the decorative shell 300 is designed to align with the edge of the first housing 100, thereby reducing the size of the connection gap created by the decorative shell 300 and the first housing 100 at the interface region.
In other embodiments, the decorative case 300 covers the outer surface of the second housing 200, and in particular, the decorative case 300 can cover the second housing entirely on the outside of the second housing, thereby optimizing the visual effect of the appearance.
In some embodiments, the outer shapes of the first housing 100, the second housing 200 and the decorative case 300 may be designed according to the actual product needs applied thereto.
The outer contours of the first housing 100, the second housing 200 and the decorative case 300 may be designed in a cambered surface, or the outer contours of the first housing 100, the second housing 200 and the decorative case 300 may be designed in a flat plate structure, which is not limited thereto.
In addition, the number of connection points between the first and second cases 100 and 200 and the number of connection points between the decorative case 300 and the second case 200 are designed mainly according to the overall size of the case assembly.
In some embodiments, the mount is of unitary construction with the expansion member 2. Specifically, the mounting seat and the expansion member 2 are taken as an integral part, and the expansion member 2 is directly formed on the mounting seat, so that the connection strength between the mounting seat and the expansion member 2 is higher. And when in actual use, the expansion part 2 is not required to be additionally assembled with the mounting seat, so that the operation personnel can use the expansion part conveniently.
Wherein, in order to facilitate the connection between the bolt 3 and the expansion member 2, a first mounting hole 12 may be further provided on the mounting seat, the first mounting hole 12 is coaxial and communicated with the threaded through hole, and the bolt 3 passes through the first mounting hole 12 and is screwed in the threaded through hole. Specifically, the bolt 3 sequentially passes through the mounting hole 201 and the first mounting hole 12 to be connected in the threaded through hole, and in the process of screwing the bolt 3, the second housing 200 can be tightly attached to the mounting seat 1, so that the positioning and supporting contact surface of the second housing 200 is increased, and the connection reliability is further improved.
In the case of the mounting base and the expansion member 2 having the integrated structure, the mounting portion 21 is integrally and fixedly mounted on the mounting base, and in the case of the expansion portion 22, since it is required to be movable with respect to the fixed limiting portion 11, the expansion portion 22 is suspended from the mounting base.
In another embodiment, the mounting seat and the expansion member 2 are of a split type structure. Specifically, in order to facilitate the attachment of the expansion member 2 to the mount, a second attachment hole (not shown) may be provided in the mount, and the attachment portion 21 may be provided in the second attachment hole. For example: the second mounting hole is a screw-threaded through hole, and the outer circumference of the mounting portion 21 is formed with an external screw thread, so that the mounting portion 21 can be screw-coupled in the second mounting hole. At the same time, the second mounting hole will be coaxial and in communication with the threaded through hole.
As a preferred embodiment, in order to enable the two expansion portions 22 to be reliably pushed up and expanded by the bolt 3, the opposed surfaces of the two expansion portions 22 are formed with grooves 221, and the depth and/or width of the grooves 221 is gradually reduced in a direction away from the mounting portion 21. Specifically, a channel for the entry of the bolt 3 is formed between the grooves 221 in which the two expansion portions 22 are oppositely arranged, and during the tightening of the bolt 3, the bolt 3 enters between the two expansion portions 22 and moves along the grooves 221. And since the depth and/or width of the groove 221 becomes gradually smaller in a direction away from the mounting portion 21, the two expansion portions 22 are simultaneously expanded and unfolded after the bolt 3 is continuously inserted between the two expansion portions 22.
In one embodiment, in order to improve the connection reliability, a connection portion 121 may be disposed between the free ends of the two expansion portions 22, specifically, the connection portion 121 is connected between the free ends of the two expansion portions 22, so that when a force is applied to the expansion portions 22 by the bolts 3, the free ends of the two expansion portions 22 are not displaced, and thus, deformation occurs in the middle region of the expansion portions 22, so that the expansion portions 22 apply a more uniform clamping force to the rib plate 101.
In some embodiments, in order to improve the clamping reliability of the rib plate 101, tooth structures are respectively provided on opposite surfaces of the fixing limiter 11 and the expansion portion 22. Specifically, the fixed limiting portion 11 is provided with the first tooth structure 10, the expansion portion 22 is provided with the second tooth structure 220, and after the rib plate 101 is clamped by the fixed limiting portion 11 and the expansion portion 22, the first tooth structure 10 and the second tooth structure 220 on two sides of the rib plate 101 can deform by a certain amount due to extrusion, so that the first tooth structure 10 and the second tooth structure 220 are more tightly attached to the rib plate 101. Meanwhile, the first tooth structures 10 and the second tooth structures 220 arranged on two sides of the rib plate 101 can uniformly apply pressure to the rib plate 101 along the length direction of the rib plate 101, so that the connection reliability is improved more effectively.
In another embodiment, regarding the structural form of the mounting base 1 and the expansion member 2, the fixing and limiting portion 11 disposed on the mounting base 1 is integrally formed in a plate-like structure, and the expansion member 2 may be integrally formed in the form of an expansion tube, which is not limited herein.
In an embodiment, in order to facilitate the operator to quickly complete the connection and assembly between the decorative shell and the second shell 200 on site, a first clamping portion is disposed on the inner wall of the decorative shell 300, and a second clamping portion is disposed on the outer wall of the second shell 200, where the first clamping portion and the second clamping portion are clamped together.
Specifically, the first clamping portion and the second clamping portion are matched with each other, so that the decorative shell 300 can be quickly and conveniently assembled on the second shell 200.
Meanwhile, the clamping connection part is shielded by the decorative case 300 due to the clamping mode, so as to optimize the appearance effect.
In some embodiments, the first clamping portion and the second clamping portion have various structural forms. The following is an example.
The first clamping portion comprises a claw 301, the second clamping portion comprises a clamping groove 202, and the claw 301 is clamped in the clamping groove 202.
Specifically, when the decorative case 300 is coupled to the second case 200 by snap-fitting, the claws 301 are snapped into the grooves 202, and the claws 301 are engaged with the grooves 202 to couple the decorative case 300 to the second case 200.
In order to improve the connection strength, the first clamping portion further includes an insertion tongue 302, the second clamping portion further includes a positioning groove 203, and the insertion tongue 302 is inserted into the positioning groove 203.
Specifically, in assembly, the insert tongue 302 is inserted into the positioning groove 203 to pre-position the decorative shell 300 and the second housing 200, and then the claw 301 is clamped in the clamping groove 202 to complete the assembly between the decorative shell 300 and the second housing 200.
Wherein, the opening directions of the positioning groove 203 and the clamping groove 202 are arranged back to back. In this way, the connection portion formed by the insert tongue and the clamping groove 202 and the connection portion formed by the insert tongue 302 and the positioning groove 203 are matched with each other, so that the decorative shell 300 can be firmly and reliably installed and fixed on the outer wall of the second shell 200.
In another embodiment, since the claws 301 and the insert tongues 302 are located on the inner wall of the decorative case 300, the inner wall of the decorative case 300 is matched with the outer wall of the second housing 200 when assembled, so that it is difficult for an operator to insert the insert tongues 302 into the positioning grooves 203 accurately.
For this, a first guide chute 204 and a second guide chute 205 may be provided on the outer surface of the second housing, the first guide chute 204 extending to the clamping groove 202 and the second guide chute 205 extending to the positioning groove 203.
In particular, during assembly, the operator may first place the pawl 301 in the first guide chute 204 while having the tongue disposed in the second guide chute 205.
Then, the operator will slide the decorative case 300 along the first guide chute 204 and the second guide chute 205 so that the insert tongue 302 is accurately inserted into the positioning groove 203 and finally the claw 301 is caught in the catching groove 202.
Under the guiding action of the first guiding chute 204 and the second guiding chute 205, the guiding chute can cooperate with the insert tongue 302 and the claw 301 to guide the decorative shell 300 to slide.
Further, in the initial stage of installation, the decorative shell 300 and the second shell 200 may be further separated from each other, so that an operator can observe the positions of the claw 301 and the insert tongue 302 conveniently, and further ensure that the claw 301 and the insert tongue 302 are accurately placed in the corresponding guide sliding groove.
Then, the distance between the decorative case 300 and the second housing 200 becomes smaller gradually during the sliding along the guiding chute, and the operator relies on the guiding action of the guiding chute to ensure that the insert tongue 302 is inserted into the positioning slot 203 first.
Finally, the claws 301 are engaged in the slots 202, so that the decorative shell 300 and the second housing 200 are firmly connected together.
In another embodiment, to facilitate positioning and assembling the first and second housings 100 and 200, a groove 103 may be provided on the rib 101, and an edge of the second housing 200 is caught in the groove 103.
Specifically, during the assembly of the first and second cases 100 and 200, the first and second cases 100 and 200 may be preassembled by inserting the edge of the second case 200 into the groove 103.
Then, the relative position between the first housing 100 and the second housing 200 is adjusted so that the mounting hole 201 is aligned with the threaded through hole.
Finally, a bolt is passed through the mounting hole 201 and screwed in the screw through hole, so that the first housing 100 and the second housing 200 are firmly and reliably assembled together.
Wherein, in order to accurately position the positional relationship between the first housing 100 and the second housing 200, the assembly accuracy is improved. A step surface 104 may be provided on the inner wall of the first housing 100, and a positioning rib 206 may be provided on the outer wall of the second housing 200, where the positioning rib 206 abuts against the step surface 104.
Specifically, in assembling the first and second cases 100 and 200, the above-described process of performing the pre-positioning through the groove 103 is referred to, so that the first case 100 and the second case 200 are pre-assembled together. Meanwhile, after the edge of the second housing 200 is inserted into the groove 103, the positioning rib 206 on the second housing 200 will abut against the step surface 104, so that the first housing 100 and the second housing 200 can be accurately positioned, and the overall assembly quality of the housing assembly can be improved.
In a preferred embodiment, in order to further improve connection reliability, a shield 207 extending to the outside may be provided at an edge of the second housing 200. Specifically, at the time of assembly, the auxiliary module 400 for assembly may be assembled in advance to the second housing 200, that is, the mount 1 is engaged with the mounting groove formed by the shroud 207, the expansion member 2 is mounted on the mount 1, and the bolt 3 passes through the second housing 200 via the mounting hole 201 and is screwed into the screw through hole. At this time, the bolt 3 is simply screwed at the front end portion in the screw through hole, so that the clamping space formed between the fixing stopper portion 11 and the expansion portion 22 is large, to facilitate the operator to insert the rib plate 101 into the clamping space. Then, the position between the first housing 100 and the second housing 200 is adjusted so that the rib 101 is inserted into the holding space and so that the edge of the shroud 207 abuts against the inner wall of the first housing 100. Finally, the first housing 100 and the second housing 200 are aligned and the bolts are tightened. At this time, on the one hand, the first housing 100 and the second housing 200 are connected together by the auxiliary module 400 for assembly, and on the other hand, the cover 207 can play a role of supporting and positioning the first housing 100 and the second housing 200, and the cover 207 can also position and protect the auxiliary module for assembly, thereby improving connection reliability.
The above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be apparent to one skilled in the art that modifications may be made to the technical solutions described in the foregoing embodiments, or equivalents may be substituted for some of the technical features thereof; such modifications and substitutions do not depart from the spirit and scope of the corresponding technical solutions.
