In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise specifically defined.

Existing electrical equipment such as an electric fan used for air supply or a table lamp used for lighting usually includes a useful electric main body and a support base, wherein the support base includes a base and a supporting mechanism installed on the base. However, the support base of the electrical equipment either cannot be stored, thereby occupying too much indoor space, making the indoor layout seem too messy, or it can only be stored by disassembling the support mechanism and the chassis, which is very troublesome. Therefore, it is desired to have a support base that can not only be stored to improve space utilization, but also can stably support an electric main body such as an electronic device or an electric device after being unfolded. Among them, electronic devices include but are not limited to mobile phones, tablet computers, notebook computers, etc., and electrical devices include but are not limited to fans, desk lamps, projectors, etc.

In the present invention, a storage slot is provided on the chassis and/or the main body of the electricity consumption as a whole, and then the support mechanism is rotatably installed on the chassis, and at the same time, a locking mechanism for locking and unlocking the chassis and the support mechanism is configured, so that when When the support mechanism is in the use position, the chassis and the support mechanism can be locked by the locking mechanism, so that the support mechanism cannot rotate relative to the chassis, so as to remain in the use position without shaking; and the locking mechanism can also release the chassis and the support mechanism Locking enables the support mechanism to be rotated from the use position to the storage position, and when the support mechanism is in the storage position, the support mechanism is stored in the storage slot of the chassis and/or the main body of electricity.

In some possible implementations, the locking force between the support mechanism and the chassis can be adjusted to achieve stable support for the power user under different application environments, and avoid the power user from shaking or turning over.

By rotatably setting the support mechanism on the chassis, and cooperating with a locking mechanism that can lock and unlock the support mechanism and the chassis, when the support base needs to be stored, the chassis and the support mechanism can be unlocked by the locking mechanism, and then Rotate the support mechanism to store the support mechanism into the storage slot of the chassis and/or the main body of electricity to reduce the space occupied by the support base during storage; and when the support base needs to be unfolded for use, rotate the support mechanism relative to the base to an appropriate angle , That is, after rotating to the use position of the supporting mechanism, the supporting mechanism and the chassis are locked by the locking mechanism, so that the supporting mechanism is fixed with respect to the chassis, so as to stably support the fan main body/table lamp main body and other electric main bodies.

Several optional implementation manners are described below in conjunction with the drawings.

Example 1

This embodiment provides a support seat, as shown in Figures 1 to 4, which includes a chassis 1, a support mechanism, and a locking mechanism 31, wherein a receiving groove 133 is provided on the top of the chassis 1, and the bottom end of the support mechanism can be Rotatingly mounted on the chassis 1, the locking mechanism 31 is configured to lock and unlock the supporting mechanism and the chassis 1. The top end of the supporting mechanism is used to install the main body of electricity.

In this embodiment, the supporting mechanism may be a rod with a fixed length, or may be a telescopic mechanism 5 that can be telescoped, or may also be a folding mechanism that can be folded and can be manually locked or self-locked when opened, for example, A linkage mechanism similar to a three-section stick is selected as the folding mechanism. When the linkages are in the same straight line, the linkages can be manually or automatically locked.

In order to make the description more concise, in this embodiment and other embodiments, the telescopic mechanism 5 will be used as an example to describe the technical solution of this embodiment, but those skilled in the art should understand that as long as the length of the supporting mechanism is the same as the length of the receiving slot 133 Adaptation, even if the length of the support mechanism is fixed, it can also be stored, and the volume of the support base after storage is compared to the volume of the support base that cannot be stored or is occupied by the support base without the storage slot 133 The volume is significantly reduced, thereby improving space utilization.

The telescopic mechanism 5 has two states: storage and use. In the storage state, the telescopic mechanism 5 is in the storage position, and in the use state, the telescopic mechanism 5 is in the use position. Specifically, when the telescopic mechanism 5 is in the storage state, it is accommodated in the storage groove 133 formed on the top surface of the chassis 1. When the telescopic mechanism 5 is in use, the locking mechanism 31 can lock it with the chassis 1. In this way, the telescopic mechanism 5 is maintained at the use position so that the main body of electricity can be used normally. The use position may be a position where the support mechanism is perpendicular to the chassis 1, for example.

Exemplarily, as shown in FIGS. 1 and 2, the chassis 1 includes a top shell 11, which is a cylindrical structure with an opening at the top. Of course, in other examples, it can also be oval or polygonal. Cylindrical structure. A plurality of anti-skid pads or pulleys can be arranged on the bottom of the chassis 1.

The top shell 11 has an accommodation space 131, and an installation boss 14 is provided in the accommodation space 131. A part of the mounting boss 14 forms a receiving groove 133, and the receiving groove 133 communicates with the accommodating space 131; another part of the mounting boss 14 forms a mounting groove 132, and the mounting groove 132 and the receiving groove 133 pass through. Exemplarily, the width of the mounting groove 132 may be smaller than the width of the receiving groove 133 as shown in FIG. 1, or the width of the mounting groove 132 may be the same as or larger than the width of the receiving groove 133.

The telescopic mechanism 5 includes an inner sleeve 51 and a telescopic rod 53 that can be telescoped. When the support mechanism is a folding mechanism, the support mechanism may include an inner sleeve 51 and a folding rod that can be folded. The hinged end (bottom end in Figure 2) of the inner sleeve 51 is rotatably connected to the chassis 1, the plug-in end (top end in Figure 2) of the inner sleeve 51 has an opening, and the connecting end of the telescopic rod 53 (the bottom end in Figure 2 is The bottom end) is inserted into the inner sleeve 51 from the opening at the top end of the inner sleeve 51 and is firmly connected to the inner sleeve 51. The installation end of the telescopic rod 53 (the top end in FIG. 2) is equipped with an electrical main body, and The electricity main body can be turned upside down. The structure of the telescopic rod 53 can be the same as that of the prior art, and will not be repeated here.

As shown in FIGS. 2 and 3, in some possible implementation manners, the telescopic rod 53 may be firmly connected to the inner wall of the inner sleeve 51 through a connecting head 52 provided at the bottom end. A corresponding limit structure can also be provided between the inner sleeve 51 and the telescopic rod 53 to avoid the risk of shaking that may occur when the telescopic rod 53 with a smaller radial size is inserted into the inner sleeve 51 with a larger radial size. , In order to improve the stability of the main body of electricity.

2 and 3, the bottom end of the inner sleeve 51 extends to one side or both sides to form a rotating shaft 511, it is easy to understand that when two rotating shafts 511 are provided at the bottom end of the inner sleeve 51, this The two rotating shafts 511 are usually coaxially arranged. In order to facilitate the electrical connection between the circuit board, battery, etc. installed in the boss 14 and the electrical main body installed at the top of the telescopic mechanism 5, one or both ends of the rotating shaft 511 can be set in a hollow structure to facilitate the passage of the connecting wire. The hollow rotating shaft 511 can also be provided with reinforcing ribs 512 extending along the axial direction of the rotating shaft 511 to improve the structural strength of the rotating shaft 511 and avoid damage to the rotating shaft 511 when it is externally squeezed, thereby improving the inner sleeve The service life of the barrel 51.

As shown in Figure 2, one or two mounting shaft holes 141 are formed in the mounting groove 132 of the mounting boss 14, and the rotating shaft 511 is rotatably mounted in the mounting shaft hole 141, so that the telescopic mechanism 5 can rotate along The rotation axis of the shaft 511 rotates to be received in the receiving groove 133 provided on the mounting boss 14. It should be understood that, in other examples, a rotating shaft 511 may also be provided on the groove wall of the mounting groove 132, and a corresponding mounting shaft hole 141 for installing the rotating shaft 511 is provided on the inner sleeve 51. It can be understood that by arranging the rotating shaft 511 on the inner sleeve 51, the structural strength of the telescopic mechanism 5 can be improved, so as to stably support the electrical equipment installed at the top of the telescopic rod 53 to avoid shaking or turning over.

Exemplarily, a damping washer 4 may be further provided between the rotating shaft 511 and the mounting shaft hole 141 to increase the frictional force of the rotating shaft 511 when rotating in the mounting shaft hole 141. The damping washer 4 may be an annular structure fitted on the rotating shaft 511, or a C-shaped structure fastened in the rotating shaft 511 or the mounting shaft hole 141 or other structures. For example, Figures 2 and 3 show an achievable structure of the damping washer 4, which includes a plate-shaped portion contacting the shaft and four feet contacting the mounting shaft hole 141. The four feet can be set At the four corners of the rectangular plate-shaped part. By arranging the damping washer 4, when the weight or volume of the electrical main body mounted on the top of the telescopic rod 53 is small, the telescopic mechanism 5 can be rotated to any position, and can be used in the direction of the friction provided by the damping washer 4. Fixed relative to chassis 1.

As shown in Figures 1 to 4, the present embodiment is also equipped with a locking mechanism 31 for locking and unlocking the inner sleeve 51 and the chassis 11, and the inner sleeve 51 and the chassis 11 can be locked by the locking mechanism 31, so as to expand and contract. The mechanism 5 can stably support the electrical main body to avoid the risk of shaking or rollover caused by only the damping washer 4, and because the locking mechanism 31 has a large locking force on the chassis 1 and the inner sleeve 51, it also It can increase the weight and/or volume of the electric main body supported by the top of the telescopic rod 53 and ensure the safe use of the electric main body without the risk of tipping or damage caused by the fact that the telescopic rod 53 is not locked relative to the chassis 1 .

As shown in Figures 1 to 4, the locking mechanism 31 includes: a first locking member 313, an outer sleeve 311, and a limiting structure. The outer sleeve 311 is sleeved on the inner sleeve 51 and can rotate relative to the inner sleeve 51 to lock or unlock the inner sleeve 51 and the chassis 1. The limiting structure is installed on the inner sleeve 51 and located above the outer sleeve 311, and the limiting structure is used to limit the outer sleeve 311 to move on the inner sleeve 51. The first locking member 313 is sleeved on the inner sleeve 51 and located below the outer sleeve 311.

It should be noted that when the outer sleeve 311 rotates relative to the inner sleeve 51 and approaches the chassis 1, the outer sleeve 311 abuts the first locking member 313 on the chassis 1 to lock the inner sleeve 51, thereby making it stretchable The mechanism 5 is locked with the chassis 1; when the outer sleeve 311 rotates relative to the inner sleeve 51 and moves away from the chassis 1, the outer sleeve 311 releases the first locking member 313, and then releases the lock of the inner sleeve 51, so This also unlocks the telescopic mechanism 5 and the chassis 1 so as to drive the telescopic mechanism 5 to rotate relative to the chassis 1. In addition, it should also be pointed out that the first locking member 313 and the limiting structure are not the restrictive structure of the locking mechanism 31 of this embodiment. In some examples, any or all of the locking member and the limiting structure may be omitted. These can be clearly understood through the following description.

Illustratively, as shown in FIGS. 2-4, the outer surface of the inner sleeve 51 is provided with an external thread 513, and the inner surface of the outer sleeve 311 is provided with a corresponding internal thread. The outer sleeve 311 can be locked and fixed to the inner sleeve 51 through the thread structure matched with the inner sleeve 51, that is, through the thread structure of the outer sleeve 311 and the inner sleeve 51, and the outer sleeve 311, The pressing effect of a locking member 313 and the mounting boss 14 can firmly fix the inner sleeve 51 on the chassis 1 to prevent it from shaking, thereby ensuring that the electrical main body installed on the top of the telescopic rod 53 does not shake or When turned sideways, even if the main power user has a relatively large weight and/or volume, the telescopic mechanism 5 can still stably support the main power user.

Further, by rotating the outer sleeve 311, the pressing force between the outer sleeve 311, the first locking member 313 and the chassis 1 can also be adjusted to quickly adjust the locking force between the inner sleeve 51 and the chassis 1 so as to adapt to The electric main body with different weight and/or different volume avoids shaking or turning over of the electric main body installed at the top of the telescopic rod 53.

For example, when the weight and/or volume of the electrical main body mounted on the top of the telescopic rod 53 is large, when the outer sleeve 311 is rotated downward, the outer sleeve 311 can be rotated down a little more distance to increase the application of the outer sleeve 311 on The pressing force of the first locking member 313 increases the locking force between the inner sleeve 51 and the mounting boss 14 and avoids shaking or turning over of the electrical main body; and the weight of the electrical main body installed at the top of the telescopic rod 53 And/or when the volume is small, when rotating the outer sleeve 311 downwards, you can rotate it down a little bit less, so as to reduce the pressing force of the outer sleeve 311 on the locking member, thereby reducing the first locking The pressing force between the member 313 and the mounting boss 14 prevents the locking member from crushing the rotating shaft 511 arranged in a hollow structure under the premise of ensuring that the electrical main body does not shake, thereby improving the service life of the inner sleeve 51.

It can be seen that the support seat of this embodiment cooperates with each other through the thread locking action between the outer sleeve 311 and the inner sleeve 51 and the pressing action between the outer sleeve 311, the first locking member 313 and the chassis 1 , Thereby realizing the locking between the telescopic mechanism 5 and the chassis 1, avoiding the electric main body shaking or turning over due to insufficient friction between the rotating shaft of the inner sleeve 51 and the mounting shaft hole 141 of the mounting boss 14 In addition, in this embodiment, the locking force between the inner sleeve 51 and the mounting boss 14 can be adjusted by rotating the outer sleeve 311 downward, so as to adapt to electrical main bodies with different weights and/or volumes. .

In this embodiment, the first locking member 313 may be provided separately from the outer sleeve 311 or formed as an integral structure. Taking FIG. 2 and FIG. 3 as an example, an annular groove is provided on the outer sleeve 311, and correspondingly, a slider slidably disposed in the annular groove is provided on the first locking member 313. With this arrangement, when the locking member abuts the chassis 1, the pressing force of the outer sleeve 311, the locking member and the chassis 1 can also be adjusted by rotating the outer sleeve 311. In some possible implementations, a plurality of sliders evenly arranged along the circumferential direction of the inner sleeve 51 may be provided on the first locking member 313.

It should be noted that the first locking member 313 may be a circular, oval or polygonal ring-shaped member sleeved on the outer sleeve 311, or may be a C-shaped member installed at the bottom end of the outer sleeve 311. Taking FIGS. 2 and 3 as an example, in some possible implementations, the first locking member 313 includes an annular locking portion 3131 and an orienting portion 3133, wherein the annular locking portion 3131 is configured to have a substantially rectangular shape, and the orienting portion The 3133 extends downward from the locking portion 3131 so as to be inserted into the receiving groove 133 to restrict the first locking member 313 to follow the outer sleeve 311 to rotate. Specifically, when the outer sleeve 311 is rotated downwards, the first locking member 313 assembled at the bottom end of the outer sleeve 311 moves downward. When the positioning portion of the first locking member 313 is inserted into the receiving groove 133, due to the orientation portion 3133 interferes with the groove wall of the receiving groove 133, even if the frictional resistance between the outer sleeve 311 and the first locking member 313 is greater than the frictional force between the first locking member 313 and the surface of the mounting boss 14, the first locking member 313 is also It does not follow the rotation of the outer sleeve 311, so that the guiding effect is achieved to a certain extent. Yes, the first locking member 313 is always maintained at this position to ensure that the locking portion 3131 and the chassis 1 always have a larger contact area , Thereby improving the locking effect of the chassis 1 and the inner sleeve 51.

It should also be pointed out that the first locking member 313 is not an essential part of the outer sleeve 311 to realize the locking of the inner sleeve 51 and the chassis 1. In some examples, the first locking member 313 may not be provided, but only through the outer sleeve. The bottom surface of the sleeve 311 abuts against the surface of the mounting boss 14, and the inner sleeve 51 and the mounting boss 14 can also be locked. It can be understood that by providing the first locking member 313, the first locking member 313 with different shapes can be conveniently used to increase the contact area with the mounting boss 14, so as to improve the locking between the inner sleeve 51 and the mounting boss 14. And when the first locking member 313 is further provided with the directional portion 3133, the locking member can also be prevented from rotating with the outer sleeve 311, thereby ensuring that the contact area between the first locking member 313 and the mounting boss 14 is maximized to improve Compaction effect. Based on the foregoing knowledge, in this embodiment, since the area of the bottom surface of the first locking member 313 is larger than the area of the bottom surface of the outer sleeve 311, the locking force between the locking mechanism 31 and the chassis 1 can be increased, thereby increasing the inner sleeve Locking function between 51 and chassis 1.

As shown in FIGS. 2 to 4, the limiting structure provided on the inner sleeve 51 includes a holding ring 317 and a lock ring 315, wherein the lock ring 315 and the holding ring 317 are snap-fitted and assembled.

For example, referring to FIG. 4, a first locking hole 517 and a first slot 515 are provided on the upper end of the inner sleeve 51, and a first locking block 3175 is provided on the holding ring 317. When the holding ring 317 and the inner sleeve 51 are assembled, the first locking block 3175 is assembled with the first locking hole 517 to realize the assembly between the holding ring 317 and the inner sleeve 51. The first slot 515 on the inner sleeve 51 can be provided in multiple, and the wall part between two adjacent first slots 515 can be elastically deformed. Correspondingly, the inner wall of the holding ring 317 is provided with a The top protrusion 3177 is used to squeeze the wall part between the two adjacent first slots 515 of the inner sleeve 51, so that the wall part is elastically deformed to clamp and insert the inner sleeve. The telescopic rod 53 in the sleeve 51. A second locking hole 3173 is provided on the holding ring 317, and a second locking block 3153 and a longitudinally extending protrusion 3151 are protrudingly provided on the inner wall of the locking ring 315. When assembling the lock ring 315 and the holding ring 317, first insert the protruding strip 3151 into the longitudinal opening 3171, and then cooperate with the second lock hole 3173 through the second lock block 3153 to realize the assembly between the lock ring 315 and the holding ring 317 .

In some possible implementations, flanges can also be provided at the bottom of the holding ring 317 and/or the lock ring 315 to further improve the limiting effect of the outer sleeve 311. Specifically, when the outer sleeve 311 rotates upward to abut against the flanging of the holding ring 317 and the lock ring 315 or both, the outer sleeve 311 can no longer continue to move upward.

Please continue to refer to FIGS. 2 to 4. In some examples, at least one arc-shaped groove 531 may be provided on the telescopic rod 53, and an arc-shaped protrusion 3155 is provided on the lock ring 315. The arc-shaped protrusion 3155 and the arc The fit of the shaped groove 531 makes the telescopic rod 53 and the lock ring 315 closely fit and position. Since the lock ring 315 closely fits with the inner sleeve 51 through the holding ring 317, it ensures that the telescopic rod 53 and the inner sleeve Close assembly between 51.

In some possible implementations, at least two longitudinal arc-shaped grooves 531 are provided on the telescopic rod 53 at intervals. Correspondingly, two arc-shaped protrusions 3155 are provided on the lock ring 315 to match the two arc-shaped grooves. The grooves 531 cooperate. For example, one arc-shaped groove 531 is provided on the left and right sides of the telescopic rod 53, or one arc-shaped groove 531 is provided on the front and rear sides of the telescopic rod 53, that is, two The arc-shaped grooves 531 are symmetrically arranged with respect to the axis of the telescopic rod 53 to improve the stability of the telescopic rod 53 when it is extended and contracted.

It should be pointed out that in some examples, the limiting structure may not be provided or the limiting structure may be different from the above-mentioned holding ring 317 and lock ring 315. For example, the top end of the inner sleeve 51 may be formed with an outward flange or The wall thickness of the top end of the inner sleeve 51 is increased to realize the limiting effect when the outer sleeve 311 rotates upward.

When the support base of this embodiment needs to be unfolded, first pull the telescopic rod 53 obliquely upward, so that the telescopic rod 53 drives the inner sleeve 51 to turn upward about 90° around the rotation axis of the rotating shaft 511 until the inner sleeve 51 Rotate to a predetermined angle relative to the chassis 1, for example, vertical, and then turn the outer sleeve 311 downward, so that the outer sleeve 311 drives the locking member to abut against the mounting boss 14, thereby locking the inner sleeve 51 perpendicular to the chassis 1. When you need to fold and store, first rotate the outer sleeve 311 upward to unlock the locking member and the mounting boss 14, and then push the telescopic rod 53 diagonally downward, so that the telescopic rod 53 drives the inner sleeve 51 around the axis of rotation The rotation axis of the 511 is turned downward by about 90° so as to receive the telescopic rod 53 and the inner sleeve 51 in the receiving groove 133.

That is, in these examples, there is no partial or complete storage slot 133 shown in FIGS. 5-10. When the fan main body 9 or the lamp main body 10 is flipped and stacked on the main chassis 1, the telescopic rod 53 and the inner sleeve 51 are stored in the fan main body 9 or the receiving slot 133 of the lamp main body.

Example 2

This embodiment is a modification made on the basis of any of the above embodiments, and mainly changes the locking and fitting manner of the inner sleeve 51 and the chassis 1 in the support base.

Figures 13-15 show a foldable fan, including a support base and a fan body 9 mounted on the top end of the telescopic rod 53 through a turning and locking mechanism 7, the turning and locking mechanism 7 is used to realize the fan body 9 and the telescopic rod 53 Between rotation and locking. Wherein, the fan body 9 includes a rear cover 97, and the back of the rear cover 97 is provided with an annular protruding strip 973. The annular protruding strip 973 can be integrally formed with the rear cover 97 and surrounds the rear cover 97 to form a receiving cavity 975. When the foldable fan is folded and stored, the locking structure and the telescopic mechanism 5 are stored in the storage cavity 975. The flip lock mechanism 7 may be the structure in any of the above embodiments, or may be obtained by simple deformation of any structure.

The following mainly introduces the structure of the support base, so as to understand the main difference between this embodiment and other embodiments more clearly, and the same or similar structures will not be repeated.

As shown in Figures 13-15, the chassis 1 includes a top case 11 and a bottom cover 12, the top case 11 is provided on the bottom cover 12, so that the top case 11 and the bottom cover 12 are enclosed for mounting such as circuit boards 155, Storage space for batteries and counterweight 16.

Exemplarily, the top shell 11 has a side wall extending downward, and the bottom cover 12 is substantially a circular plate-shaped structure. A first mounting seat 19 and a control switch 151 may be installed on the top shell 11. The first mounting seat 19 may be, for example, a cylindrical structure protruding from the top shell 11 as shown in FIG. 15. Of course, in some examples, the first mounting seat 19 may also be provided on the bottom surface of the bottom cover 12.

A mounting groove for installing the inner sleeve 51 and an escape opening for avoiding when the inner sleeve 51 rotates are provided in the first mounting seat 19, so that when the outer sleeve 311 moves down to the first mounting seat 19 When there is an overlapping part, the inner sleeve 51 and the chassis 1 are locked, see Fig. 13; when the outer sleeve 311 moves upward and away from the mounting seat, the inner sleeve 51 and the chassis 1 are unlocked, see Fig. 14, at this time, The inner sleeve 51 can rotate around the central axis of the rotating shaft 511 to be received in the receiving cavity 975 of the rear cover 97. It can be seen that by providing the first mounting seat 19, even if the outer sleeve 311 does not abut the chassis, the chassis 1 and the inner sleeve 51 can still be locked.

Exemplarily, the first mounting seat 19 may also be provided with a threaded portion 191, and the outer sleeve 311 is threadedly connected with the threaded portion 191 to further improve the locking force of the outer sleeve 311 to the chassis 1 and the inner sleeve 51.

In some possible implementation manners, the first mounting seat 19 is an annular protrusion extending upward from the mounting boss 14, and the annular protrusion has an escape opening toward the center of the chassis 1. Exemplarily, the threaded portion 191 is an external thread provided on the outer surface of the protrusion. When the outer sleeve 311 rotates downward, the inner thread provided on the inner surface of the outer sleeve can be threaded with the outer thread on the outer surface of the protrusion. In order to lock the inner sleeve 51 and the chassis 1.

In other possible implementation manners, the first mounting seat 19 is a circular recessed portion formed by the mounting boss 14 recessed downward, and the circular recessed portion has an escape opening toward the center of the chassis 1. Exemplarily, the threaded portion 191 is an internal thread provided on the inner wall of the recessed portion. Correspondingly, an external thread matching the internal thread is provided on the outer surface of the outer sleeve 311, so that when the outer sleeve 311 rotates downward , The external thread provided on the outer surface thereof can be threadedly connected with the internal thread provided on the inner wall of the recess, so as to lock the inner sleeve 51 and the chassis 1.

In some other possible implementation manners, the above-mentioned annular protrusion and annular recess can be used in combination to strengthen the locking force of the inner sleeve 51 and the chassis 1.

It should be pointed out that if the receiving slot 133 is provided on the chassis 1, the receiving slot 133 can communicate with the escape opening. If the receiving slot 133 is provided on the main body of the electricity, when the main body of the electricity is turned over and stacked on the chassis 1, The receiving groove 133 provided on the power consumption main body communicates with the escape opening.

The support seat of this embodiment can realize the locking of the inner sleeve 51 and the chassis 1 through the interference effect of the outer sleeve 311 and the first mounting seat 19, and can also be increased by further pushing the outer sleeve 311 against the chassis 1 Locking force to improve the locking effect. When the inner sleeve 51 and the chassis 1 are locked by the threaded connection of the outer sleeve 311, the inner sleeve 51 and the mounting boss 14, it can have a good locking effect and can ensure that the telescopic rod 53 can be stable. Supporting the power consumption main body installed at the top end thereof, even if the power consumption main body has a relatively large weight and/or volume, the power consumption main body can still be prevented from shaking or turning over.

Example 3

This embodiment provides a support base, and the main difference from the first embodiment is that the locking mechanism is different.

As shown in Figures 16-18, the locking mechanism 33 of this embodiment is installed in an assembly cavity 519 provided at one end of the rotating shaft 511. The locking mechanism 33 includes a fixed head 331, a fixed piece 333, an adjusting bolt 335, and an adjusting片337. The fixed head 331 is clamped and installed in the assembly cavity 519 and can rotate synchronously with the rotating shaft 511.

For example, in some implementations, the fixing head 331 is provided with a clamping protrusion 3311 extending into the assembly cavity 519, and the assembly cavity 519 is provided with abutting upper and lower surfaces of the clamping protrusion 3311. The limiting rib 514 is used to make the fixed head 331 rotate synchronously with the rotating shaft 511. In other implementations, the fixed head 331 may be fastened and installed in the assembly cavity 519 by means of screwing, bonding or any other suitable fastening method, or may also be integrally formed with the rotating shaft 511 as One-piece structure.

One end of the fixing piece 333 is fixedly installed on the chassis 1. For example, the fixing piece 333 can be firmly connected to the mounting boss 14 provided in the chassis 1 by screwing, riveting, bonding or integral molding. The other end of the fixing piece 333 extends in the axial direction of the rotating shaft 511, and a through hole coaxial with the rotating shaft 511 is provided on the fixing piece 333.

The adjusting piece 337 is disposed between the fixing piece 333 and the fixing head 331, and/or between the fixing piece 333 and the adjusting bolt 335, and the adjusting piece 337 is used to increase the friction resistance. In some implementations, the adjustment piece 337 has a rough surface.

The adjusting bolt 335 passes through the adjusting piece 337, the fixing piece 333 and the fixing head 331 for screw assembly, and the adjusting bolt 335 is used to adjust the friction between the fixing piece 333 and the fixing head 331.

In the support base of this embodiment, the compression force between the fixing head 331, the fixing piece 333, and the adjusting piece 337 can be adjusted by adjusting the tightness of the connection between the bolt 335 and the fixing head 331, so as to realize the alignment between the inner sleeve 51 and the chassis 1 The adjustment of the interlocking force in order to adapt to the electric main body with different weight and/or volume. For example, when the weight and/or volume of the electrical main body is large, the adjusting bolt 335 is tightened to make the pressing force between the fixing piece 333, the adjusting piece 337 and the fixing head 331 larger, so as to increase the inner sleeve. The locking force between 51 and the chassis 1 ensures that the telescopic rod 53 will not shake or roll over; when the weight and/or volume of the electrical main body is small, loosen the adjusting bolt 335 to make the fixing piece 333 and the adjustment The pressing force between the piece 337 and the fixed head 331 is reduced to reduce the locking force between the inner sleeve 51 and the chassis 1 and avoid excessive wear and tear of the adjusting piece 337 that may cause the electric main body to shake or roll over. risk.

In some possible implementations, an elastic member such as an elastic rubber or a spring may be provided between the adjusting bolt 335 and the adjusting piece 337, and/or between the fixing head 331 and the adjusting piece 337, so as to prevent The adjusting piece 337 exerts a certain pre-tightening force to ensure that the adjusting piece 337 can always be in close contact with the fixed piece 333 and/or the fixed head 331, thereby avoiding friction between the adjusting piece 337 and the fixed piece 333 and/or the fixed head 331 The force is reduced due to the wear of the adjustment piece 337.

It can be seen that by arranging the fixing head 331 on the rotating shaft 511 and the fixing piece 333 on the chassis 1, and allowing the adjusting bolt 335 to pass through the coaxial bolt holes provided on the fixing head 331 and the fixing piece 333, The rotating shaft 511 and the chassis 1 are rotatably connected together, so that the locking force between the inner sleeve 51 and the chassis 1 can be adjusted, and then the inner sleeve 51 can be rotated to any position relative to the chassis 1 The chassis 1 is locked and then kept in this position without shaking or turning over under the influence of the weight and/or volume of the electrical main body mounted on the top of the telescopic rod 53.

Furthermore, adjusting pieces 337 may be provided on both sides of the fixing piece 333 to further increase the friction resistance, so that the supporting mechanism can more stably support a heavy and/or larger power consumer.

It is easy to understand that, in some examples, the adjusting bolt 335 can be integrally formed on the fixed head 331 or the fixed piece 333, or can be manufactured separately, and then fastened to the fixed head 331 or the fixed head 331 or by using bolts, rivets or other fastening methods.
