[0003] Generally, a door handle includes a handle part and a connecting part fixed to the door panel. In the prior art, the connecting part is generally fixed to the door panel by screws or preset in the door panel, and the door panel is provided with a through hole corresponding to the connecting part. When the staff needs to disassemble, replace, or repair, they need to use a variety of tools, and the disassembly is relatively cumbersome. Utility Model Content

[0004] In order to improve the disassembly and assembly efficiency of the door handle, this application provides a door handle that can be quickly disassembled and assembled.

[0005] The door handle that can be quickly disassembled and assembled provided by this application adopts the following technical solutions:

[0006] A door handle that can be quickly disassembled and assembled includes a handle part and a connecting part. The connecting part includes a fixing block for fixing to the door panel, a connecting column inserted and matched with the fixing block, and a locking component. Two groups of limiting blocks are arranged at intervals along the axial direction of the connecting column. The fixing block is provided with an installation groove into which the connecting column is inserted. The side wall of the installation groove is provided with a circumferential sliding groove for the limiting block to rotate. The locking component is arranged on the side wall of the circumferential sliding groove. When the connecting column rotates, the limiting block drives the locking piece to slide along the axis of the fixing block and lock with the connecting column.

[0007] By adopting the above technical solutions, when using the above door handle, first fix the fixing block on the door panel, then connect and fix the handle part and the connecting column, and then insert the connecting column into the installation groove of the fixing block. After the connecting column is inserted to the bottom, rotate the handle part circumferentially, so that the limiting block slides in the circumferential sliding groove. The limiting block abuts against the locking component and drives the locking component to slide axially. When the locking component slides, it locks with the fixing block, realizing the locking of the connecting column and the fixing block. The operation is convenient and the structure is simple.

[0008] Optionally, the locking component includes a locking slider, a locking spring sleeved on the locking block, and a locking plug slidably arranged at one end of the locking block. The locking plug slides along the radial direction of the connecting column. The side wall of the connecting column has a locking groove for the locking plug to insert.

[0009] By adopting the above technical solution, the structural composition of the locking component is disclosed. The locking slider slides axially within the fixed block. After the block to be locked and the locking groove correspond to each other, the locking block and the locking groove are inserted and matched to achieve axial and radial fixation of the connecting column, with stable connection and relatively ideal connection strength.

[0010] Optionally, the locking slider is provided with an insertion block chute for the sliding of the locking block, and an elastic member is arranged in the insertion block chute of the locking slider.

[0011] By adopting the above technical solution, due to the setting of the insertion block chute, before the connecting column is installed, the whole locking block shrinks and is located within the insertion block chute. After the block to be locked and the locking groove correspond to each other, the locking block automatically inserts into the locking slot under the action of the elastic member to achieve automatic locking.

[0012] Optionally, the locking slider is provided with a first guiding surface for the pushing of the limiting block, and the locking block is provided with a second guiding surface for guiding expansion and contraction.

[0013] By adopting the above technical solution, the setting of the first guiding surface facilitates the limiting block to push the locking slider, making the locking operation more labor-saving. When the handle unlocks, the locking slider resets towards the circumferential chute under the action of the locking spring. The setting of the second guiding surface facilitates the locking block to retract back into the insertion block chute again, ensuring that the end of the limiting block is located in the circumferential chute when the connecting column is installed next time.

[0014] Optionally, an unlocking column for unlocking the locking component is arranged on the connecting column. The connecting column is provided with an unlocking chute for the sliding of the unlocking column and an unlocking spring sleeved on the unlocking column, and the unlocking chute communicates with the locking groove.

[0015] By adopting the above technical solution, the setting of the unlocking column facilitates the operator to disengage the locking block from the locking groove, achieving axial fixation of the connecting column and the fixed block. The unlocking structure is simple and the operation is convenient.

[0016] Optionally, a sealing elastic ring is arranged between the inner wall of the unlocking chute and the side wall of the unlocking column.

[0017] By adopting the above technical solution, the setting of the sealing elastic ring can seal the unlocking chute, reducing the probability of external water vapor and impurities entering the fixed block and ensuring the service life of the locking component.

[0018] Optionally, the unlocking column and the unlocking chute are rotationally matched. An unlocking limit block is arranged at the end of the unlocking column, and a pressing groove adapted to the unlocking limit block is arranged on the side wall of the connecting column.

[0019] By adopting the above technical solution, the unlocking column is rotatably installed in the unlocking chute, and the setting of the unlocking limit block can keep it in the locked state all the time when the connecting column is not disassembled. When the handle needs to be disassembled or assembled, rotate the unlocking column to make the unlocking limit block correspond to the pressing groove.

[0020] Optionally, the handle member includes a first handle part and a second handle part. The connecting columns are arranged on both the first handle part and the second handle part. The first handle part is provided with a handle insertion block, and the second handle part is provided with a handle insertion slot for the handle insertion block to insert into. The unlocking direction of the first handle part is away from the handle insertion slot.

[0021] By adopting the above technical solution, the handle member is integrally divided into two parts, and the two handle parts are respectively locked with the connecting member. When both the first handle part and the second handle part are locked, the handle insertion block just cooperates with the handle insertion slot to realize the locking of the two handle parts.

[0022] Optionally, the handle member is provided with a connecting threaded groove for installing the connecting column.

[0023] By adopting the above technical solution, the connecting column is fixed to the handle member through the connecting threaded groove, which has the effects of convenient operation and stable connection.

[0024] Optionally, a covering sleeve is arranged on the first handle part. The covering sleeve includes a fixed cylinder fixed to the first handle part and a sliding cylinder slidably installed in the fixed cylinder. The sliding cylinder is provided with a fixed buckle, and the second handle part is provided with a fixed buckle groove for cooperating with the fixed buckle.

[0025] By adopting the above technical solution, the setting of the covering sleeve can cover the matching part of the handle insertion slot and the handle insertion block, and at the same time, through the covering sleeve, the connection strength between the first handle part and the second handle part is improved.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] Through the setting of the limit block and the locking component, the present application realizes the quick locking of the connecting column and the fixed block, with convenient operation and high connection strength;

[0028] Through the setting of the unlocking column, the present application facilitates the operator to disengage the locking insertion block from the locking groove, and the unlocking structure is simple and the operation is convenient;

[0037] The following will Figures 1-6 make a further detailed description of the present application in conjunction with the attached

[0038] An embodiment of the present application discloses a door handle with quick disassembly and assembly.

[0039] Referring to Figure 1 and Figure 2 , a door handle with quick disassembly and assembly includes a handle member 1 and a connecting member 2. The connecting member 2 includes a fixing block 3 for fixing to the door panel, a connecting column 4 inserted and matched with the fixing block 3, and a locking assembly 5. The handle member 1 is a U-shaped handle, which includes a first handle part 11 and a second handle part 12.

[0040] The fixing block 3 is integrally rectangular, and one end face thereof has a mounting groove 31 for inserting the connecting column 4. A plurality of supporting ear parts 32 are integrally arranged on the outer side wall of the fixing block 3, and through holes penetrating through both end faces are provided on the supporting ear parts 32. The fixing block 3 is first inserted into the groove of the door panel, and then bolted to the door panel through the supporting ear parts 32.

[0041] Referring to Figure 2 , Figure 3 and Figure 4 , both the first pulling part 11 and the second pulling part 12 are L-shaped, and connecting threaded grooves 111 for installing the connecting column 4 are provided at the ends away from each other. The connecting column 4 has a threaded part that is fixedly fitted with the connecting threaded groove 111. The two pulling parts are first fixed to the connecting column 4, and then inserted and fixed to the fixing block 3 on the door panel.

[0042] The first pulling part 11 is provided with a pulling hand inserting block 112 at one end facing the second pulling part 12, and the second pulling part 12 has a pulling hand inserting slot 121 for inserting the pulling hand inserting block 112. Among them, the pulling hand inserting slot 121 is located on one side of the locking direction of the first pulling part 11, that is, the locking directions of the first pulling part 11 and the second pulling part 12 are opposite, so that when the first pulling part 11 and the second pulling part 12 are locked, the pulling hand inserting slot 121 and the pulling hand inserting block 112 are in an inserted and mated state, and at this time, the overall shape of the two pulling parts is U-shaped.

[0043] A covering sleeve 13 for covering the pulling hand inserting slot 121 is further installed on the first pulling part 11. The covering sleeve 13 includes a fixed cylinder 131 fixed to the first pulling part 11 and a sliding cylinder 132 slidably installed in the fixed cylinder 131. A fixing buckle is arranged inside the sliding cylinder 132, and the structure of the fixing buckle is the same as that of the hook structure in the prior art (not marked in the figure), and a fixing buckle groove 122 for the fixing buckle 1321 to be inserted into is provided on the second pulling part 12.

[0044] Referring to Figure 3 , the connecting column 4 is a circular cylinder, and two groups of limiting blocks 41 are arranged at intervals on the side wall along the axial direction thereof, and the two groups of limiting blocks 41 are located on the same axis. The fixing block 3 is provided with a positioning slot 311 corresponding to the limiting blocks 41 for insertion on the inner wall of the mounting groove 31, and the fixing block 3 is provided with a circumferential sliding groove 312 for the two groups of limiting blocks 41 to slide circumferentially in the positioning slot 311. The two circumferential sliding grooves 312 are respectively located at opposite ends of the positioning slot 311. When the connecting column 4 is completely inserted into the mounting groove 31, the two groups of limiting blocks 41 respectively correspond to the two circumferential sliding grooves 312, and then the connecting column 4 is rotated to make the limiting blocks 41 slide in the circumferential sliding grooves 312 to realize the preliminary fixing of the connecting column 4 and the fixing block 3.

[0045] Combined with Figure 4 and Figure 5, Two groups of limit blocks 41 are respectively engaged with a group of locking components 5. The two groups of locking components 5 are arranged on the side wall of the circumferential chute 312, and the fixed block 3 has a receiving groove 33 for arranging the locking components 5. The receiving groove 33 extends along the axial direction of the connecting column 4.

[0046] The locking component 5 includes a locking slider 51, a locking spring 52 sleeved on the locking slider 51, and a locking plug 53 slidably installed at one end of the locking slider 51. The whole locking slider 51 slides along the extending direction of the receiving groove 33, and one end of the receiving groove 33 communicates with the circumferential chute 312. The fixed block 3 is provided with an extension plate in the receiving groove 33 for fixing one end of the locking spring 52, and the other end of the locking spring 52 is fixed to the side wall of the locking slider 51. In the normal state of the locking spring 52, one end of the locking slider 51 passes out of the receiving groove 33 and is arranged in the circumferential chute 312. Among them, in order to facilitate the limit block 41 to push the locking slider 51, the locking slider 51 is provided with a first guiding surface 511 at one end facing the circumferential chute 312.

[0047] The locking slider 51 is provided with a plug chute 512 for the locking plug 53 to slide at one end far from the first guiding surface 511, and the locking plug 53 slides in the plug chute 512 along the radial direction of the connecting column 4. The locking slider 51 is provided with an elastic member 513 in the plug chute 512, and the elastic member 513 is a spring member. Through the setting of the elastic member 513, before the limit block 41 pushes the locking slider 51, the whole locking plug 53 is in the plug chute 512, and the elastic member 513 is in a compressed state.

[0048] The outer side wall of the connecting column 4 has a locking groove 42 for the locking plug 53 to insert, and the fixed block 3 communicates the other end of the receiving groove 33 with the locking groove 42, so that after the connecting column 4 rotates, the locking plug 53 moves towards the locking groove 42, and the locking plug 53 automatically inserts into the locking groove 42 under the action of the elastic member 513, realizing the final fixation of the connecting column 4 and the fixed block 3, and at the same time fixing the axial and circumferential directions of the connecting column 4, with stable connection and relatively stable strength.

[0049] For the convenience of disassembly and assembly, an unlocking column 43 for unlocking the locking component 5 is arranged on the connecting column 4. The connecting column 4 has an unlocking chute 44 for the unlocking column 43 to slide and an unlocking spring 45 sleeved on the unlocking chute 44, and the unlocking chute 44 communicates with the locking groove 42. The connecting column 4 is provided with a contact plate for fixing one end of the unlocking spring 45 on the inner wall of the unlocking chute 44, and the other end of the unlocking spring 45 abuts against the unlocking column 43. The fixed block 3 has an operation through hole 34 corresponding to the unlocking chute 44 and communicating with the installation groove 31.

[0050] When it is necessary to remove the connecting column 4, the operator presses down the unlocking column 43 at the operation through hole 34, so that the unlocking insertion block retracts back into the insertion block sliding groove 512 again, releasing the circumferential limit of the unlocking assembly on the connecting column 4, and then reversely rotates the connecting column 4, so that the limiting block 41 slides from the circumferential sliding groove 312 to the positioning slot 311. Wherein, second guiding surfaces 531 are further arranged on one side of the two locking insertion blocks 53 away from each other. The arrangement of the second guiding surfaces 531 facilitates the locking insertion blocks 53 to return to the accommodating groove 33 again under the action of the locking spring 52 when the connecting column 4 is unlocked and rotated.

[0051] Referring to Figure 4 and Figure 6 , in order to reduce the situation where the unlocking column 43 is pressed due to misoperation, an unlocking limiting block 431 is further arranged at the end of the unlocking column 43, and the unlocking column 43 is also rotationally matched with the connecting column 4. The unlocking limiting block 431 is integrally strip-shaped, and the end of the unlocking sliding groove 44 has a pressing groove 441 that cooperates with the unlocking limiting block 431. When the unlocking limiting block 431 and the pressing groove 441 are staggered and do not coincide in the radial direction, the unlocking column 43 as a whole cannot be pressed. Rotate the unlocking column 43 so that the unlocking limiting block 431 and the pressing groove 441 correspond, and the unlocking limiting block 431 and the pressing groove 441 coincide in the radial direction. At this time, the unlocking column 43 can be pressed to achieve unlocking. The fixing block 3 is provided with an operating rod 35 for controlling the rotation of the unlocking column 43 at the operation through hole 34. The end face of the operating rod 35 is provided with a cross slot to facilitate the operator to rotate the unlocking column 43. The supporting ear part 32 is located on the side of the operating rod 35 close to the door panel.

[0052] Wherein, a sealing elastic ring 46 is further installed between the outer wall of the unlocking column 43 and the inner wall of the unlocking sliding groove 44. The outer side of the sealing elastic ring 46 is fixed to the inner wall of the unlocking sliding groove 44, and the inner side is in sealing contact with the outer wall of the unlocking.

[0053] The implementation principle of a quickly detachable door handle in an embodiment of the present application is as follows: The fixing block 3 is installed on the door panel by bolts, and the handle part 1 and the connecting column 4 are fixedly connected by threads; then the connecting column 4 is inserted into the installation groove 31 of the fixing block 3. After the connecting column 4 is inserted to the bottom, the first handle part 11 and the second handle part 12 are rotated circumferentially, so that the limiting block 41 slides in the circumferential sliding groove 312, and the locking insertion block 53 is inserted into the locking groove 42 to realize the fixation of the connecting column 4 and the fixing block 3.

[0054] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
