Description
Technical Field
[0001] The invention relates to the field of household appliances, and in particular to a wire tube connector and a wire tube connecting assembly. Background Art
[0002] When installing wire conduits, it is often necessary to connect the ends of two wire conduits based on the spatial structure of the equipment or building.
[0003] When two wire tubes need to be connected, the wire tubes to be connected are connected at both ends through a larger connecting tube in the middle. In this way, a three-section wire tube is connected successfully. However, this method currently has certain limitations. For example, when the length of the wire tube at the other end is not enough, or the wire tube is too long after installation, you can only replace the wire tube or connect another wire tube to the end of the wire tube or cut off the wire tube, which is more troublesome. Summary of the invention

The wire tube connector includes: a connecting body, a first docking structure arranged at the first end of the connecting body, and a second docking structure arranged at the second end of the connecting body. The first docking structure is used to connect to the first wire tube with a selectable clamping length from the axial direction, and the second docking structure is used to squeeze the inner wall of the second wire tube for connection.

[0008] The plurality of first wire tube limiting structures can be selectively arranged at different positions of the plurality of first connection limiting structures so that the docking member can adjust its axial position on the wire tube connector.
[0009] Preferably, the first wire tube limiting structure is a first limiting step, and the first connection limiting structure is a first limiting groove; or, the first wire tube limiting structure is a first limiting groove, and the first connection limiting structure is a first limiting step.
[0010] Preferably, the first limiting step is an annular step structure, the first limiting groove is an annular groove structure, and the docking piece is formed by docking a first half docking piece and a second half docking piece.
[0011] Preferably, the butting surfaces of the first half butting piece and the second half butting piece are step surfaces.
[0012] Preferably, the second docking structure is a hook body protruding from the outer periphery of the second end of the wire tube connector.
[0013] Preferably, the hook body is detachably arranged on the outer periphery of the second end of the wire tube connector.
[0014] Preferably, an accommodating cavity for mounting the hook body is provided on the outer periphery of the second end of the wire tube connector.
[0015] Preferably, the hook body is further provided with: a hook body mounting portion and a first limiting end located at the first end of the hook body mounting portion; the hook body is arranged at the second end of the hook body mounting portion, and the hook body mounting portion is arranged in the accommodating cavity, and the accommodating cavity includes a first limiting surface located on the inner wall of the cavity corresponding to the first limiting end, a second limiting surface corresponding to the second end of the hook body mounting portion, and an opening for exposing the hook body.

[0018] Furthermore, in this embodiment, the docking piece adopts a half-structure setting. There is no need to rotate the wire tube during installation. It is directly connected to the first limiting groove or step of the wire tube connector by docking the two halves, thereby coping with the situation where the L-shaped wire tube cannot rotate.

[0027] DETAILED DESCRIPTION
[0028] The specific implementation of the socket and the power-on / off structure of the present invention is further described below in conjunction with the embodiments given in the accompanying drawings. The socket and the power-on / off structure of the present invention are not limited to the description of the following embodiments.
[0029] like Figure 1 As shown, this embodiment provides a wire tube connector for connecting a first wire tube and a second wire tube 4. Specifically, the wire tube connector 2 includes: a connecting body, a first docking structure 21 arranged at the first end of the connecting body, and a second docking structure 22 arranged at the second end of the connecting body. The first docking structure 21 is used to connect with the first wire tube 1 from an axial direction with a selectable clamping length, and the second docking structure 22 is used to squeeze the inner wall of the second wire tube 4 for connection.
[0030] In this embodiment, the connection body is a columnar structure, which may be cylindrical or non-cylindrical. Of course, based on the fact that both the first wire tube and the second wire tube 4 are cylindrical, it is a better embodiment to adopt a cylindrical structure for the connection body.
[0031] In this embodiment, combined with Figure 1-3 As shown, the first docking structure 21 is a plurality of first connection limiting structures 211 arranged on the periphery of the first end of the connecting body, the connecting end of the first wire tube is provided with a docking piece 10, and the inner wall of the docking piece 10 is provided with at least a first wire tube limiting structure 101.
[0032] In this embodiment, the plurality of first wire tube limiting structures 101 can be selectively disposed at different positions of the plurality of first connection limiting structures 211 so that the docking member 10 can adjust its axial position on the wire tube connector 2 .
[0033] As a specific implementation method, Figure 4 and Figure 5As shown, the first wire tube limiting structure 101 is a first limiting step, the first connection limiting structure 211 is a first limiting groove, and the first limiting step 101 and the first limiting groove 211 can be engaged with each other to form a mutual limit. It can be seen that if the first limiting steps 101 are arranged at the same distance and the first limiting grooves 211 are also arranged at the same distance, the length of the setting area of the first limiting step 101 is smaller than the length of the setting area of the first limiting groove 211 (axial direction), so that the docking member 10 can be adjusted in the axial direction of the wire tube connector 2.
[0034] Specifically, the first limiting step 101 is an annular step structure, the first limiting groove 211 is an annular groove structure, and the docking piece 10 is formed by docking a first half docking piece 11 and a second half docking piece 12. The annular groove structure can be formed by a plurality of step structures arranged in parallel along the axial direction, or it can be directly formed by the outer peripheral wall of the wire tube connector 2 being recessed inward. When the first limiting groove 211 is an annular groove, the docking piece 10 can only be installed in the first limiting groove 211 by docking two halves, otherwise the first limiting step 101 cannot be engaged with the first limiting groove 211. This method is particularly suitable when facing an L-shaped wire tube, because the L-shaped wire tube cannot be rotated during installation, so the method of docking two halves is particularly suitable.
[0035] Of course, when both ends of the wire tube are rotatable or one end is rotatable, if the first limiting groove 211 is provided with a notch in the axial direction, and the length of the first limiting step 101 is the same as or less than the length of the notch, the first limiting step 101 and the first limiting groove 211 can be inserted and rotated in the direction of the notch to form an engagement.
[0036] In this embodiment, the first half docking member 11 and the second half docking member 12 can be connected by a clamp.
[0037] For further information, see Figure 1 and Figure 5 The butt joint surfaces of the first half butt joint part 11 and the second half butt joint part 12 are step surfaces (not shown in the figure), and the use of step surfaces for butt joint can form accurate multi-directional positioning (radial and circumferential).
[0038] As another specific implementation, the first wire tube limiting structure 101 may be a first limiting groove, and the first connection limiting structure 211 may be a first limiting step, that is, the structures of the two may be swapped and still have the same positioning effect.
[0039] In this embodiment, if Figure 3As shown, the second docking structure 22 is a hook body 220 protruding from the outer periphery of the second end of the wire tube connector 2. The hook body 220 is used to embed into the inner surface 42 of the second wire tube 4 during docking to form an axial limit so that the second wire tube 4 cannot be separated. The hook body 220 can be one or more.
[0040] As a further improvement, the hook body 220 is detachably arranged on the outer periphery of the second end of the wire tube connector 2. The detachable structure allows the wire tube connector 2 to still be used when the hook body 220 is damaged (for example, when the second wire tube 4 needs to be removed again), and only the hook body 220 needs to be replaced.
[0041] Specific, combined Figure 6 As shown, a receiving cavity 24 for installing the hook body 220 is provided on the outer periphery of the second end of the wire tube connector 2 .
[0042] Among them, combined Figure 7 As shown, the hook body 220 is further provided with: a hook body mounting portion 221 and a first limiting end 222 located at the first end of the hook body mounting portion 221; the hook body 220 is arranged at the second end of the hook body mounting portion 221, and the hook body mounting portion 221 is arranged in the accommodating cavity 24, and the accommodating cavity 24 includes a first limiting surface 241 located on the inner wall of the cavity corresponding to the first limiting end 222, a second limiting surface 242 corresponding to the second end of the hook body mounting portion 221, and an opening 243 for exposing the hook body 220. When docking and installing with the second wire tube 4, the hook body 220 will not easily fall out of the accommodating cavity 24 under the pressure of the inner surface 42 of the second wire tube 4.
[0043] In this embodiment, the hook bodies 220 are arranged in pairs on the outer periphery of the second end of the wire tube connector 2 and are symmetrically arranged to each other, so that the force on the second wire tube 4 is more uniform and the docking reliability is better.
[0044] The process of installing the first wire tube and the second wire tube 4 by the wire tube installation member 2 of this embodiment is as follows:
[0045] When installing the wire tube, first install the hook body 220, first install the first limiting end 222 of the hook body installation part 221 into the accommodating cavity 24 of the wire tube connector 2, push the hook body 220 so that the first limiting end 222 of the hook body installation part 221 contacts the first limiting surface 241, and at the same time, the other end of the hook body installation part 221 also enters the accommodating cavity 24, and the other end of the hook body installation part 221 contacts the second limiting surface 242, and the hook body 220 exposes the opening 243;
[0046] After the hook body 220 is installed, the wire tube connector 2 is installed into the docking piece 10 of the first wire tube. The first limiting groove 211 cooperates with the first limiting step 101 of the docking piece 10 to control the position of the wire tube connector 2 in the docking piece 10, and the first half docking piece 11 and the second half docking piece 12 are docked and fixed. In this way, the first wire tube is connected to the wire tube connector 2. Next, the second wire tube 4 is connected. Since the hook body 220 has been installed in the accommodating cavity 24 of the wire tube connector 2 in advance, The hook body 220 will be higher than the outer surface of the wire tube connector 2. At this time, the other end of the wire tube connector 2 is inserted into the inner surface 42 of the second wire tube 4. Since the hook body 220 is higher than the outer surface of the wire tube connector 2, as the second wire tube 4 and the wire tube connector 2 are matched, the hook body 220 will be embedded in the inner surface 42 of the second wire tube 4. Since the hook body 220 is squeezed in the accommodating cavity 24, the hook body 220 is fixed in the accommodating cavity, so the first wire tube and the second wire tube 4 are assembled.
[0047] When the position of the second wire tube 4 needs to be adjusted, it is only necessary to adjust the position of the wire tube connector 2 in the docking member 10 to adjust the position of the second wire tube 4. Such a matching structure can conveniently adjust the position of the second wire tube 4 without adding or reducing wire tubes, so that the problem of insufficient or too long length of the wire tube after installation can be easily solved.
[0048] The present invention also provides a wire pipe connection assembly for connecting a first wire pipe and a second wire pipe 4, comprising the wire pipe connector 2 and the docking member 10 as described in the above embodiment.
[0049] In the wire tube connection assembly of the embodiment of the present invention, the multiple first connection limiting structures on the outer periphery of the first end of the connecting body can be adjusted in installation position with the first wire tube limiting structure provided on the inner wall of the docking piece, so that the position of the connected wire tube can be adjusted at any time during installation, thereby solving the problem of insufficient or too long length of the wire tube after installation.
[0050] Furthermore, in this embodiment, the docking piece adopts a half-structure setting. There is no need to rotate the wire tube during installation. It is directly connected to the first limiting groove or step of the wire tube connector by docking the two halves, thereby coping with the situation where the L-shaped wire tube cannot rotate.
[0051] It should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right", "inner", "outer", etc. indicate directions or positional relationships based on directions or positional relationships shown in the accompanying drawings, or directions or positional relationships that are usually placed when in use, and are only for the convenience of description, rather than indicating that the device or element referred to must have a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish descriptions, and cannot be understood as indicating relative importance.
[0052] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
