Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, and in particular to a knob locking structure applied to a snow melting machine and the snow melting machine. Background Art

[0002] During the use of the snow melter, the fixation and sealing of the loading bucket are crucial. The existing loading bucket design generally adopts the liquid storage form. In order to facilitate cleaning and maintenance, it is usually designed as a detachable component. This design requires that the connection between the loading bucket and the machine must have good sealing performance to prevent liquid leakage. Silicone sealing rings are widely used at this interface to ensure sealing. However, while ensuring sealing, it is also necessary to ensure that the loading bucket will not loosen during use. Therefore, the connection between the loading bucket and the machine must have a reliable locking structure.

[0003] There are two common locking solutions currently used in the market:

[0004] The first is a screw fixing solution, which uses screws and nuts to fasten the loading barrel to the machine. Although this method can provide a reliable locking effect, its operation process is relatively cumbersome. The user needs to rotate the screws multiple times to ensure sufficient tightening, and usually needs to operate the screws on the left and right sides separately. This not only increases working time, but also places higher demands on the user's patience and hands-on ability.

[0005] The second is a snap-on fixing solution, which has a snap position designed on the front of the loading barrel. The user needs to push the loading barrel to the snap position to fix it. Although this design reduces the operating steps to a certain extent, due to the presence of the sealing ring, a large interference fit needs to be overcome during assembly to ensure sealing. This requires greater force for the loading operation, and some users, especially those with less strength, may find it difficult to complete assembly and disassembly smoothly.

[0006] Both of the above solutions have the problem of inconvenient operation in actual use. Although the screw fixing solution is stable, it requires multiple rotation operations, and the whole process takes a long time, and requires users to have certain hands-on skills. For situations where frequent disassembly and assembly are required, this method is particularly inconvenient. Although the snap fixing solution reduces the number of operating steps, it requires overcoming a large reaction force during assembly, which makes it difficult for some users, especially those with insufficient strength, to operate. This not only affects the user experience, but may also lead to incorrect operations and affect the service life of the equipment.

[0007] The present invention is proposed in view of the deficiencies in the prior art. Utility Model Content

[0008] The locking structure on the snow melter in the prior art mentioned above has the technical problem of being inconvenient to operate.

[0009] The technical solution adopted by the utility model to solve its technical problems is:

[0010] A knob locking structure used on a snow melter includes knobs provided on both sides of the snow melter body and first limiting components provided on both sides of a loading bucket. Both knobs are rotatably provided on the snow melter body. A second limiting component corresponding to the first limiting component is provided on the knob. When the knob is turned, the knob can drive the second limiting component to cooperate with the first limiting component to lock the loading bucket on the snow melter body.

[0011] As described above, a knob locking structure is applied to a snow melter, each of the first limiting components includes a first limiting column, each of the second limiting components includes a limiting groove, and an opening communicating with the limiting groove is provided on the side wall of the knob, the first limiting column can enter and exit the limiting groove through the opening, and the first limiting column can be close to or against the inner side wall of the limiting groove.

[0012] In the knob locking structure applied to a snow melter as described above, the inner diameter of the limiting groove gradually decreases from the end with the opening to the end without the opening.

[0013] In the knob locking structure applied to a snow melter as described above, the limiting groove includes a first arm, a top connecting section, and a second arm connected in sequence, and the opening is located between the first arm and the second arm.

[0014] In the knob locking structure used on a snow melter as described above, the limiting groove is U-shaped, the length of the first arm is shorter than the length of the second arm, and the opening is inclined on the side wall of the knob.

[0015] The knob locking structure applied to the snow melter as described above further includes a limit assembly provided between the knob and the snow melter body, and the limit assembly can limit the rotation angle of the knob.

[0016] As described above, a knob locking structure applied to a snow melter, the limiting assembly includes a limiting groove provided on the knob and a second limiting column provided on the snow melter body, the limiting groove has a limiting channel, the second limiting column extends into the limiting groove and can move relatively in the limiting channel.

[0017] As described above, a knob locking structure applied to a snow melter, the limiting groove includes a ring-like segment and an elastic segment, one end of the elastic segment is connected to one end of the ring-like segment, and the other end of the elastic segment is at a certain distance from the other end of the ring-like segment, and the elastic segment can move on the ring-like segment toward or away from the second limiting column, and a moving space for the elastic segment to move is provided in the knob, and a limiting protrusion is provided on the side of the elastic segment facing the limiting channel, and the limiting channel includes a locking area and a moving area connected to each other, and the moving area can allow the second limiting column to move relatively therein, and the inner side wall of the locking area can cooperate with the limiting protrusion to lock the second limiting column in the locking area.

When assembling a charging barrel, the user aligns the charging barrel with the installation position on the snow melter body and easily inserts it. Then, by rotating the knobs arranged on both sides of the snow melter body, the knobs drive the second limiting member to rotate until the second limiting member is tightly matched with the first limiting member, and finally the charging barrel and the snow melter body are locked. Due to the precise fit between the limiting members, the knob locking structure can ensure the stability and sealing of the charging barrel without requiring much force. Compared with traditional screw locking and snap locking solutions, since the design of the knob takes the force transmission efficiency into consideration, the tight fit of the limiting member can be achieved through the rotation operation. The user only needs to easily rotate the knob to complete the fixing or disassembly of the charging barrel, which greatly simplifies the operating steps and improves the convenience of use.

[0030] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings.

[0031] like Figures 1 to 7 As shown, the present embodiment is a knob locking structure applied to a snow melter, comprising knobs 3 respectively arranged on both sides of the snow melter body 1 and first limiting members 4 respectively arranged on both sides of the charging bucket 2. The two knobs 3 are both rotatably arranged on the snow melter body 1, and the knob 3 is provided with a second limiting member 5 corresponding to the first limiting member 4. When the knob 3 is screwed, the knob 3 can drive the second limiting member 5 to cooperate with the first limiting member 4 to lock the charging bucket 2 on the snow melter body 1.

[0032] Specifically, the knobs 3 are provided on both sides of the snow melter body 1 and can rotate freely around their axes. The design of the knobs 3 makes it easy to turn manually, and the user can lock or unlock the knobs by rotating them. The second limiting member 5 is provided on the knob 3, and the first limiting member 4 is fixedly mounted on both sides of the charging bucket 2. When the user turns the knob 3, the second limiting member 5 will move relative to the first limiting member 4 as the knob rotates, so that the two can cooperate to achieve a stable connection between the charging bucket and the snow melter body.

[0033] Specifically, when assembling the charging bucket 2, the user aligns the charging bucket with the installation position on the snow melter body 1 and easily inserts it. Then, by rotating the knobs 3 set on both sides of the snow melter body 1, the knobs 3 drive the second limiting member 5 to rotate until the second limiting member 5 is tightly matched with the first limiting member 4, and finally the charging bucket 2 and the snow melter body 1 are locked. Due to the precise fit between the limiting members, the knob locking structure can ensure the stability and sealing of the charging bucket without requiring much force. Compared with traditional screw locking and snap locking solutions, users only need to easily rotate the knob to complete the fixing or disassembly of the charging bucket, which greatly simplifies the operation steps and improves the convenience of use.

[0034] Since the design of the knob takes the efficiency of force transmission into consideration, the tight fit of the limiting components can be achieved through rotation, which reduces the requirement for user strength and is especially suitable for users with less strength.

[0035] Furthermore, the positioning member has high matching accuracy and can achieve a good locking effect under a relatively small operating force, thereby ensuring that the charging barrel does not loosen during use while guaranteeing sealing performance.

[0036] like Figures 1 to 7 As shown, each of the first limiting members 4 of this embodiment includes a first limiting column, and each of the second limiting members 5 includes a limiting groove. An opening 31 communicating with the limiting groove is provided on the side wall of the knob 3. The first limiting column can enter and exit the limiting groove through the opening 31. The design of the limiting groove allows the first limiting column to freely enter and exit during assembly and disassembly, which is convenient for locking and unlocking.

[0037] When the knob 3 is rotated until the first limiting column is close to or abuts against the inner side wall of the limiting groove, the charging barrel 2 is locked on the snow melter body 1.

[0038] The user aligns the charging bucket 2 with the snow melter body 1 and inserts it. Then, the user rotates the knob 3. As the knob rotates, the limiting groove in the second limiting member 5 gradually aligns with the first limiting column. When the first limiting column enters the limiting groove through the opening 31, the first limiting column gradually abuts against the inner side wall of the limiting groove. At this time, the charging bucket 2 is locked on the snow melter body 1, ensuring the stability and sealing of the connection.

[0039] When the user rotates the knob 3 in the opposite direction, the first limiting post can be moved out of the limiting groove through the opening 31. By rotating the knob in the opposite direction, the first limiting post leaves the limiting groove, and the charging barrel 2 can be disassembled smoothly.

[0040] This design ensures that the first limit column can quickly cooperate with the limit groove during the rotation of the knob. The locking process is simple and efficient. In addition, the user only needs to rotate the knob to complete the locking and unlocking. The operation is simple and does not require additional tools and force. It is suitable for various user groups.

[0041] Furthermore, the coordinated design of the first limiting column and the limiting groove improves the stability of the charging barrel during use and avoids loosening problems caused by vibration or other external forces.

[0042] Preferably, in other embodiments, the first limiting column is close to the inner wall of the limiting groove, and the distance between the two is to provide a surplus for the sealing component 8. When the charging barrel 2 is inserted into the snow melter body 1, the sealing component 8 will be compressed. When the force on the charging barrel 2 is removed, the sealing component 8 will elastically recover, and at this time, the charging barrel 2 will be driven to move away from the snow melter body 1, thereby driving the first limiting column to compress the limiting groove. The design of setting the first limiting column close to the inner wall of the limiting groove and a certain distance between the two is to avoid the first limiting column from excessively compressing the limiting groove, thereby causing damage to the first limiting column or the limiting groove. A suitable design can be selected according to actual conditions.

[0043] like Figures 1 to 7 As shown, the inner diameter of the limiting groove of this embodiment gradually decreases from the end with the opening 31 to the end without the opening. With such a design, the size of the opening 31 is larger, which facilitates the first limiting column to enter the limiting groove through the opening. The larger opening 31 design allows users to not have to deliberately align during assembly, reducing the technical difficulty of the operation. The user only needs to rotate the knob normally to make the first limiting column easily enter the limiting groove, greatly improving the installation efficiency of the loading barrel and avoiding assembly difficulties caused by size mismatch. By adopting a larger opening 31, the user is more relaxed during operation and does not need to work hard to align. It is suitable for various user groups, especially users with less strength or insufficient operating experience.

[0044] Furthermore, after the first limiting column enters the limiting groove, as the knob is further rotated, the inner diameter of the limiting groove gradually decreases, so that the first limiting column can gradually approach the inner wall of the limiting groove until the inner wall of the limiting groove is against the first limiting column, which not only improves the locking stability, but also enhances the sealing of the connection to prevent liquid leakage.

[0045] like Figures 1 to 7As shown, the limiting groove of this embodiment includes a first arm 51, a top connecting section 52 and a second arm 53 connected in sequence. The top connecting section 52 connects the first arm 51 and the second arm 53 to form a connecting area of the limiting groove to maintain the overall structural strength of the limiting groove. The opening 31 is located between the first arm 51 and the second arm 53. Specifically, when the first limiting column abuts against the first arm 51, the loading bucket 2 is locked on the snow melter body 1. When the knob rotates in the reverse direction and the first limiting column abuts against the second arm 53, the knob can no longer rotate in the reverse direction, thereby avoiding excessive rotation of the knob.

[0046] Specifically, the user inserts the charging bucket 2 into the snow melter body 1, and rotates the knob 3 to make the first limiting column enter the limiting groove through the opening 31. When the knob continues to rotate, the first arm 51 approaches the first limiting column until it abuts against the first limiting column. At this time, the charging bucket 2 is locked on the snow melter body 1 to ensure stability.

[0047] With such a design, the first arm 51 and the second arm 53 form a double locking mechanism, ensuring that the charging barrel can be firmly locked when the knob is rotated into place, and preventing it from loosening or falling off due to reverse rotation.

[0048] like Figures 1 to 7 As shown, the limiting groove of this embodiment is U-shaped, with two arms, namely a first arm 51 and a second arm 53, and a top connecting section 52 connecting the two. The U-shaped structure design can provide a clear path for the first limiting column, thereby ensuring that the locking and unlocking process is smooth and reliable.

[0049] Specifically, the length of the first arm 51 is shorter than the length of the second arm 53. The short length design of the first arm 51 makes the locking process faster. When the first limit column is against the first arm 51, the locking action is completed immediately, shortening the operation time. Moreover, since the first arm 51 is shorter, the user only needs to rotate the knob a little bit to complete the locking, which greatly improves the operating efficiency.

[0050] The longer length of the second arm 53 is used to limit excessive rotation of the knob when unlocking, providing more buffer space to ensure that the knob will not be damaged or the locking effect will not be affected due to excessive rotation, thereby improving the overall service life and safety of the knob.

[0051] The opening 31 is arranged at an angle on the side wall of the knob 3. This inclined design makes the first limiting column more natural when inserted, reduces the difficulty of alignment, and ensures that the limiting column can slide smoothly into the limiting groove, thereby improving the smoothness of operation.

[0052] like Figures 1 to 7As shown, the knob locking structure of this embodiment further includes a limiting component 6 provided between the knob 3 and the snow melter body 1 , and the limiting component 6 can limit the rotation angle of the knob 3 .

[0053] When the user rotates the knob 3, the limit assembly 6 allows the knob to rotate normally within the set angle range to complete the locking or unlocking operation of the charging barrel. Once the knob rotates to the preset limit position, the limit assembly 6 will prevent the knob from continuing to rotate, thereby avoiding damage or misoperation caused by excessive rotation of the knob.

[0054] Preferably, the limit assembly 6 can work in conjunction with the limit groove, and the limit groove is locked and unlocked through the first arm 51 and the second arm 53 inside it, and the limit assembly further ensures that the knob can only rotate within a specific range, doubly ensuring the reliability and safety of the operation.

[0055] In other embodiments, the knob locking structure may also adopt a single structure of the limiting component 6 or the second arm 53 to prevent the knob 3 from over-rotating. A suitable design may be selected according to actual conditions.

[0056] like Figures 1 to 7 As shown, the limiting assembly 6 of this embodiment includes a limiting groove 61 provided on the knob 3 and a second limiting column 62 provided on the snow melter body 1, wherein the limiting groove 61 has a limiting channel 63, and the second limiting column 62 extends into the limiting groove 61 and can move relatively within the limiting channel 63.

[0057] Specifically, the limiting groove 61 is a groove structure located on the inner surface or side wall of the knob 3. The groove extends along the rotation direction of the knob to form a limiting channel 63 that can cooperate with the second limiting column 62. The limiting channel 63 is a path of a specific length and shape. The design of the channel determines the range in which the second limiting column 62 can move when the knob is rotated, thereby limiting the rotation angle of the knob.

[0058] Specifically, the second limiting column 62 is fixed on the snow melter body 1 and extends vertically or obliquely into the limiting groove 61. The function of the limiting column is to contact the inner wall of the limiting groove 61 when the knob is rotated to a certain position, and to limit the rotation range of the knob by moving in the limiting channel 63.

[0059] Specifically, when the user rotates the knob 3, the second limit column 62 can move relatively in the limit channel 63. When it rotates to the preset locking position, the second limit column 62 reaches the end of the limit channel 63, preventing the knob from continuing to rotate, ensuring that the knob stops at the locking position, and cooperates with the first arm 51 and the first limit column to complete the locking of the loading barrel, and can prevent the knob 3 from continuing to rotate in the same direction, causing the first arm 51 to over-press the first limit column.

[0060] When the knob is rotated in the reverse direction, the second limiting column 62 can move relatively in the limiting channel 63 in the opposite direction.

[0061] In other embodiments, when the knob is rotated in the opposite direction, the second limit column 62 can move relatively in the opposite direction within the limit channel 63. When the knob reaches the unlocked position, the second limit column 62 can move to the other end of the limit channel 63 to prevent the knob from continuing to rotate, thereby ensuring that the loading barrel is unlocked without over-rotation.

[0062] Specifically, through the precise design of the limit channel 63, the limit assembly can control the rotation of the knob within a specific range, avoiding mechanical failure or misoperation caused by excessive rotation, and during the movement of the second limit column 62 relative to the limit groove 61, the limit channel 63 can provide stable mechanical feedback to ensure smooth operation of the knob and avoid shaking or loosening that may occur during rotation.

[0063] Furthermore, the limit assembly effectively prevents over-rotation due to improper user operation, making locking and unlocking operations safer, especially providing additional safety protection in cases of fast operation or unskilled operation.

[0064] like Figures 1 to 7 As shown, the limiting groove 61 of this embodiment includes a ring-like segment 611 and an elastic segment 612, one end of the elastic segment 612 is connected to one end of the ring-like segment 611, and the other end of the elastic segment 612 is at a certain distance from the other end of the ring-like segment 611. The elastic segment 612 can move on the ring-like segment 611 toward or away from the second limiting column 62, and a moving space 32 for the elastic segment 612 to move is provided in the knob 3. A limiting protrusion 613 is provided on the side of the elastic segment 612 facing the limiting channel 63, and the limiting channel 63 includes a locking area 631 and a moving area 632 connected to each other. The moving area 632 can allow the second limiting column 62 to move relatively therein, and the inner side wall of the locking area 631 can cooperate with the limiting protrusion 613 to lock the second limiting column 62 in the locking area 631.

[0065] Specifically, the annular segment 611 is the main part of the limiting groove and is partially annular, and the elastic segment 612 is connected to both ends of the annular segment 611 to form a movable structure. The annular segment 611 and the elastic segment 612 are combined to form the limiting groove 61.

[0066] Specifically, when the knob is gradually turned to the preset locking position and the second limiting column 62 gradually enters the locking area 631, the second limiting column 62 can gradually force the limiting protrusion 613, thereby causing the elastic section 612 to elastically deform and move away from the second limiting column 62. When the second limiting column 62 completely enters the locking area 631, the second limiting column 62 no longer forces the limiting protrusion 613. At this time, the elastic section 612 elastically recovers, and the inner side wall of the elastic section 612, part of the side wall of the limiting protrusion 613 and the inner side wall of the locking area 631 are close to or against the second limiting column 62, so that the second limiting column 62 is locked in the locking area 631, preventing the knob from continuing to rotate, thereby completing the locking of the loading barrel.

[0067] When the user rotates the knob in the opposite direction, the second limit column 62 moves in the opposite direction relative to the limit channel 63. At this time, the second limit column 62 can gradually force the limit protrusion 613, so that the elastic section 612 elastically deforms and moves away from the second limit column 62. When the second limit column 62 completely escapes from the locking area 631 and completely enters the moving area 632, the second limit column 62 no longer forces the limit protrusion 613. At this time, the elastic section 612 elastically recovers. At this time, the inner side walls of the moving area 632 are close to or against the second limit column 62, thereby releasing the lock, and under the restriction of the inner side walls of the moving area 632, the knob is allowed to continue to rotate to the unlocked position.

[0068] Specifically, the cooperation between the limiting protrusion 613, the elastic section 612 and the locking area 631 provides a stable locking mechanism, ensuring that the knob will not rotate accidentally due to external force when in the locked position. The design of the elastic section 612 makes the operation of the knob smoother during the locking and unlocking process, reducing mechanical shock and wear. The movable design of the elastic section provides a certain degree of operational flexibility, and the locking and unlocking operations can still be carried out smoothly even in the case of slight deviation.

[0069] like Figures 1 to 7 As shown, the cross-sectional shape of the limiting protrusion 613 of this embodiment is arc-shaped. Specifically, the two sides of the limiting protrusion 613 respectively have a first arc surface 614 and a second arc surface 615. The first arc surface 614 is located in the locking area 631, and the second arc surface 615 is located in the moving area 632. Such a design can reduce the friction between the second limiting column 62 and the limiting protrusion 613 during the locking and unlocking process, and achieve smooth locking or unlocking through progressive contact of the arc surface, thereby improving the smoothness of the operation and preventing sudden jamming or jumping.

[0070] like Figures 1 to 7 As shown, a linkage shaft 7 is provided between the two knobs 3 of this embodiment to enable the two to rotate synchronously.

[0071] Specifically, the linkage shaft 7 is arranged between the two knobs 3 as a connecting component between the two. One end of the linkage shaft is connected to the first knob 3, and the other end is connected to the second knob 3. This connection method ensures the synchronous operation of the knobs. When the user rotates one of the knobs, the linkage shaft 7 will transmit the rotational force to the other knob, ensuring that the two knobs rotate synchronously at the same speed and angle, thereby ensuring that the two knobs always maintain synchronous movement. This ensures that during the locking and unlocking operations, the two knobs complete the corresponding operations at the same time, and there will be no situation where a single knob is not completely locked or unlocked. The design of the linkage shaft effectively prevents the situation where a single knob is operated incorrectly when locking or unlocking, ensuring that the charging barrel can be reliably locked or unlocked in each operation.

[0072] Furthermore, users only need to rotate one knob to complete the synchronous operation of the two knobs, which reduces the operation steps and improves the convenience and efficiency of the operation.

[0073] like Figures 1 to 7 As shown, a snow melter of the present embodiment includes a snow melter body 1, a charging barrel 2 and a knob locking structure as described in any one of the above items. A sealing assembly 8 is provided between the snow melter body 1 and the charging barrel 2. When the charging barrel 2 is locked on the snow melter body 1 through the knob locking structure, the sealing assembly 8 can seal the snow melter body 1 and the charging barrel 2.

[0074] Specifically, the snow melter body 1 is the core part of the entire device, and it contains various mechanical and electronic components used for snow melting operations. The snow melter body 1 is designed with an interface for connecting the loading bucket 2, and an installation component that cooperates with the knob locking structure. The loading bucket 2 is used to hold snow or ice to be processed. Through the knob locking structure, the loading bucket 2 can be firmly fixed on the snow melter body 1 and can be easily disassembled after the operation is completed.

[0075] Specifically, the sealing assembly 8 is an important sealing component between the charging barrel 2 and the snow melter body 1. It is usually made of elastic materials, such as silicone rings, rubber pads, etc. The assembly is located around the barrel mouth of the charging barrel 2 and corresponds to the connection port of the snow melter body 1. When the charging barrel 2 is locked on the snow melter body 1 through the knob locking structure, the sealing assembly 8 is pressed between the two to form an effective sealing layer to prevent leakage of melted snow or other liquids.

[0076] Specifically, the user places snow or ice into the loading bucket 2, then aligns the bucket opening with the interface of the snow melter body 1. By rotating the knob 3, the linkage shaft 7 drives the two knobs to rotate synchronously, and the knob locking mechanism securely fixes the loading bucket 2 to the snow melter body 1. When the loading bucket 2 is securely locked by the knob locking mechanism, the sealing assembly 8 is automatically compressed between the loading bucket and the snow melter body. The elastic material of the sealing assembly deforms under pressure, completely filling the gap between the loading bucket 2 and the snow melter body 1, forming a reliable seal.

[0077] After the operation is completed, the user rotates the knob 3 to unlock the charging barrel 2, and the sealing assembly 8 returns to its original state. The charging barrel can be easily removed and cleaned or reloaded.

[0078] Through the knob locking structure, the user can easily complete the installation and disassembly of the charging barrel, and the automatic sealing function of the sealing component 8 reduces the user's operating burden.

[0079] Preferably, a rotation channel 11 for assembling the linkage shaft 7 is provided on the snow melter body 1 . The rotation channel 11 runs through both sides of the snow melter body 1 , so that both ends of the linkage shaft 7 are connected to the knob 3 respectively.

[0080] The above examples are merely used to further illustrate the technical content of the present invention for easier understanding by the reader. However, they do not limit the implementation of the present invention to these examples. Any technical extension or reinvention based on the present invention is protected by the present invention. The scope of protection of the present invention shall be determined by the claims.
