[0001] The present application relates to the technical field of shell assembly, and in particular to a cover plate disassembly and assembly component and an industrial computer. Background Art

[0002] Electronic devices generally include a housing and a circuit structure installed inside the housing. The housing not only serves as a mounting carrier for the internal circuit structure, but also provides good protection for the internal circuit structure. The housing is generally composed of multiple separate parts assembled together. After the circuit structure is installed inside, the multiple parts are assembled and fixed to each other.

[0003] Taking an industrial computer as an example, its outer shell usually includes a chassis and a cover. One end of the chassis is open for disassembly and assembly of the circuit structure, and the cover is closed at the opening to cover and protect the internal circuit structure.

[0041] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0042] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0043] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists, A and B exist at the same time, and B exists. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0045] In the description of the embodiments of the present application, the technical terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the embodiments of the present application.

[0046] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0047] The outer shell of electronic equipment such as computers and servers usually consists of a chassis and a cover. The internal circuit structure is installed in the chassis, and the cover is detachably fixed to the chassis by screws.

[0048] Take industrial computers as an example. They are special computers used in industrial environments. In order to better protect the internal circuit structure, most industrial computers use fanless shell heat dissipation, that is, cooling fins are set on the cover to increase the heat dissipation area. The internal heat is dissipated to the outside through the chassis and the cover. The cover is generally connected to the chassis at the edge with multiple screws.

[0049] Whether it is an industrial computer or other types of electronic equipment, when hardware upgrades or maintenance are required, the cover must be removed before performing corresponding operations. The screw connection method not only requires an appropriate screwdriver, but also takes a long time to disassemble, which makes the cover disassembly and assembly operations complicated and time-consuming, affecting the efficiency of hardware upgrades or maintenance.

[0050] In this regard, the present application proposes a cover plate disassembly and assembly assembly, in which the base is responsible for the overall installation and fixation on the chassis, and the base is provided with a lifting mechanism and a clamping mechanism that are mutually connected through a transmission mechanism, wherein the clamping mechanism is responsible for clamping with the buckle on the cover plate to achieve quick assembly and fixation of the cover plate on the chassis. When removing the cover plate, the lifting mechanism will rise and lift the cover plate, while the transmission mechanism will be used to drive the clamping mechanism to move to release the clamping connection between the clamping mechanism and the buckle on the cover plate, so that the cover plate and the chassis can not only automatically release the assembly relationship, but also the cover plate will be automatically lifted by the lifting mechanism, so that the technicians can easily remove the cover plate and perform subsequent hardware-related operations in the chassis, so as to achieve easy and convenient disassembly and assembly of the cover plate.

[0051] The cover assembly provided in the present application includes but is not limited to applications in electronic devices such as industrial computers, computers, servers, and other devices whose housings are assembled in multiple parts. The following text and the accompanying drawings take the industrial computer as an example for explanation, which does not constitute a limitation on the specific application field of the cover assembly.

[0052] According to one aspect of the embodiment of the present application, an industrial computer is provided. Figure 1 , the figure shows the perspective structure of the industrial computer. As shown in the figure, the industrial computer 500 includes a cover plate disassembly assembly 100, a chassis 200 and a cover plate 300. In order to facilitate the structural display of the cover plate disassembly assembly 100 located inside the chassis 200, the chassis 200 is represented in a transparent form with gray double-dotted lines in the figure, and the same applies to the structures shown in the same way in other figures below.

[0053] The cover plate 300 is provided with a buckle 310, which is specifically provided on a side of the cover plate 300 facing the chassis 200. Figure 1The buckle 310 and the cover plate 300 are shown in an exploded state, and in the specific embodiment shown in the figure, the buckle 310 is provided with a connection hole 311, and the buckle 310 can be installed on the cover plate 300 by rivets, threaded fasteners, etc. Of course, the buckle 310 can also be an integral structure with the cover plate 300. The cover plate 300 can be provided with heat dissipation fins 320 as shown in the figure, and of course it can also be a conventional flat plate body.

[0054] The cover assembly 100 is disposed on the chassis 200, and the cover 300 is detachably connected to the chassis 200 through the cooperation of the buckle 310 and the cover assembly 100. The specific cooperation between the buckle 310 and the cover assembly 100 will be described in detail below, and will not be repeated here.

[0055] According to another aspect of the embodiment of the present application, a cover plate disassembly assembly 100 applicable to the industrial computer 500 provided in the above embodiment is provided. Figure 1 Further combining Figures 2 to 5 , the figure shows the structures of different parts of the cover plate disassembly assembly 100. The cover plate disassembly assembly 100 includes a base 110, a lifting mechanism 120, a transmission mechanism 130 and a clamping mechanism 140.

[0056] like Figure 1 As shown, the base 110 is used to be installed on the chassis 200 to serve as a carrier for mounting and fixing other mechanisms. The base 110 can adopt a shell structure as shown in the figure, and of course can also adopt a bracket, mounting plate, mounting block and other structural forms, which are not limited here.

[0057] like Figure 2 and Figure 3 As shown, the lifting mechanism 120 includes a lifting member 121 and a locking member 122. It should be noted that Figure 3 In the specific structure shown, the lifting member 121 is represented by a transparent gray double-dotted line, and the locking member 122 is covered inside the lifting member 121. The lifting member 121 is connected to the base 110 in a liftable manner along the direction shown by the z-axis, and the locking member 122 is movably connected to the base 110.

[0058] Please combine again Figure 1When installing the cover plate 300, first place the cover plate 300 downward along the z-axis direction, the bottom of the cover plate 300 will abut against the top of the lifting member 121, and the lifting member 121 will drop under the pressure of the cover plate 300. After the lifting member 121 drops into place, that is, after the cover plate 300 is installed in place, the locking member 122 moves to a state where the lifting member 121 is locked, so that it can no longer be raised or lowered, ensuring that the cover plate 300 will not be affected by the force of the lifting member 121 after being assembled. On the contrary, when removing the cover plate 300, the locking member 122 is operated to move to a state where the lifting member 121 is unlocked, so that the lifting member 121 rises and lifts the cover plate 300.

[0059] For the lifting mechanism 120, Figure 2 and Figure 3 In the illustrated embodiment, the base 110 includes a button seat 111, and a lifting member 121 is buckled on the button seat 111 and is lifted and lowered in cooperation with the outer wall of the button seat 111. For example, a slider and a slide groove, a slider and a slide rail, a roller and a slide rail, etc. can be adopted to lift and lower and slide in cooperation, and the specific details are not limited here. A lifting elastic member 123 is connected between the lifting member 121 and the button seat 111. The lifting elastic member 123 is used to provide an upward elastic force to the lifting member 121 along the direction shown by the z-axis. The lifting elastic member 123 can be a compression spring as shown in the figure, or a spring sheet, an elastic soft rubber block, etc.

[0060] An installation cavity 1111 is formed inside the button seat 111, and an opening 1112 is provided on the side wall of the button seat 111. When the lifting member 121 is lowered into place, a locking portion 1211 is provided at a position opposite to the opening 1112. In the figure, the locking portion 1211 is a bayonet, and of course it can also be a slot, a cam, etc. in other embodiments.

[0061] The locking member 122 includes a locking rod 1222 rotatably disposed in the installation cavity 1111 via a first rotating shaft 1221, and one end of the locking rod 1222 has a locking protrusion 12221. In the specific embodiment shown in the figure, in order to improve the stability of limiting the lifting member 121, there are two locking rods 1222 and they are arranged in mirror symmetry. In other embodiments, more or only one locking rod 1222 can also be provided, and the principles are the same.

[0062] For locking of the lifting member 121, Figure 4aAs shown in the locking state from a top-down perspective, when the lifting member 121 is lowered into place, that is, when the cover plate 300 is installed in place, the locking rod 1222 on the right side rotates in a clockwise direction relative to its first rotating shaft 1221, and the locking rod 1222 on the left side rotates in a counterclockwise direction relative to its first rotating shaft 1221 (hereinafter, only the movement relationship of the locking rod 1222 on the right side is explained, and the locking rod 1222 on the left side moves in an opposite state), the locking protrusion 12221 passes through the opening 1112 and engages with the locking portion 1211, limiting the lifting member 121 from rising, and ensuring that the cover plate 300 is not subjected to the force of the lifting member 121 after installation.

[0063] Please continue reading Figure 4a A button 124 is also provided on the button seat 111. The button 124 cooperates with the end of the locking rod 1222 that is away from the locking protrusion 12221. Specifically, it can be matched through the inclined surface friction shown in the figure, or it can be matched flexibly by means of a thick hole and a thin shaft. The specific matching method is not limited here, as long as it is ensured that when the button 124 is pressed, the button 124 can drive the locking rod 1222 on the right side to rotate in the counterclockwise direction.

[0064] For unlocking the lifting member 121, specifically, Figure 4b As shown in the unlocked state from a top-down perspective, when the button 124 is pressed inward, the button 124 drives the locking rod 1222 on the right to rotate counterclockwise, and the locking protrusion 12221 is separated from the locking portion 1211, that is, the locking protrusion 12221 and the locking portion 1211 are released from the clamping relationship, and the lifting limit of the lifting member 121 is released, so that under the elastic force of the lifting elastic member 123, the lifting member 121 will drive the cover plate 300 to rise to lift it.

[0065] Furthermore, if Figure 4b As shown, a locking elastic member 125 can be arranged between the locking rod 1222 and the button seat 111, and the locking elastic member 125 is used to provide a reset elastic force to rotate in a clockwise direction to the right locking rod 1222, so that when the lifting member 121 is lowered into place and the button 124 is not pressed, the locking protrusion 12221 remains in a state of being engaged with the locking portion 1211, thereby ensuring that the cover plate 300 and the chassis 200 remain in a state of being assembled and fixed to each other.

[0066] In the embodiment shown in the accompanying drawings, a button switch is used to unlock the lifting member 121, which makes it easier to remove the cover 300 from the chassis 200. Specifically, when removing the cover 300, no auxiliary tools are required. Only the button 124 needs to be pressed by hand, and the cover 300 will automatically pop up under the action of the lifting member 121. Then, the cover 300 can be easily removed to replace or maintain the internal circuit structure.

[0067] The above is the specific structure and working principle of the lifting mechanism 120 provided in the embodiment corresponding to the accompanying drawings, and the specific implementation of the lifting mechanism 120 is not limited thereto. For example, the lifting member 121 is a spring pin that can be elastically extended relative to the base 110, and the locking member 122 is a latch that can slide relative to the base 110, a baffle that can rotate relative to the base 110, etc. In the unlocked state, the spring pin extends relative to the base 110. When the cover 300 is placed, the cover 300 presses down the spring pin to shrink it. After being pressed down to the right position, the latch or baffle can be moved to a locked state that is connected to the spring pin and limits it through an electric drive member, an elastic reset member or manual operation, ensuring that the cover 300 will not be affected by the force of the spring pin after being assembled. When it is necessary to remove the cover 300, the latch or baffle is reversely operated to release the extension and contraction restriction of the spring pin, and the spring pin automatically extends and lifts the cover 300 to facilitate the subsequent removal and removal of the cover 300.

[0068] For the transmission mechanism 130 and the clamping mechanism 140, please combine Figures 2 to 6 In the specific embodiment shown in the figure, the clamping mechanism 140 can be slidably connected to the base 110. Figure 2 As shown, the outer wall of the lifting member 121 is provided with a driving rack 1212 extending along the lifting direction (i.e., the direction shown by the z-axis in the figure), and the transmission mechanism 130 includes a gear set 131 and a transmission slider 132. Figures 2 to 6 As shown, the transmission slider 132 is connected to the clamping mechanism 140 , a driven rack 1321 is provided on the transmission slider 132 , and the gear set 131 is transmission-connected between the driving rack 1212 and the driven rack 1321 .

[0069] like Figure 1 and Figure 6 As shown, the base 110 further includes a sliding seat 112, and the sliding seat 112 is disposed on at least one side of the button seat 111. Figure 5 and Figure 6 As shown, the clamping mechanism 140 is slidably connected to the sliding seat 112 along a first direction (the direction shown by the x-axis in the figure), and the transmission slider 132 is slidably connected to the sliding seat 112 along a second direction (the direction shown by the y-axis in the figure). The transmission slider 132 and the clamping mechanism 140 are frictionally matched through an inclined surface, and a first elastic member 143 is connected between the side of the clamping mechanism 140 away from the transmission slider 132 and the sliding seat 112, and the first elastic member 143 is used to provide an elastic force for the clamping mechanism 140 to slide toward the transmission slider 132.

[0070] like Figure 5 and Figure 6 As shown, the locking mechanism 140 includes a locking slider 141 ( Figure 5The locking slider 141 and the locking block 142 are arranged relatively along the direction indicated by the x-axis, and are both slidably connected to the sliding seat 112 along the direction indicated by the x-axis.

[0071] A first elastic member 143 is connected between the side of the block 142 facing away from the locking slider 141 and the sliding seat 112, a second elastic member 144 is connected between the block 142 and the locking slider 141, and the transmission slider 132 and the side of the locking slider 141 facing away from the second elastic member 144 are frictionally engaged through inclined surfaces (the first inclined surface 1322 and the second inclined surface 1411 in the figure).

[0072] like Figure 2 and Figure 3 As shown in , the gear set 131 can use helical gear transmission to convert the lifting movement of the lifting member 121 along the z-axis direction into the sliding movement of the transmission slider 132 along the y-axis direction, and can also be configured with gears of different diameters to mesh with each other to achieve the purpose of speed reduction and torque increase. In other embodiments, a worm gear, a lead screw module and other mechanisms can also be used to convert the lifting movement of the lifting member 121 into the sliding movement of the transmission slider 132 in different directions.

[0073] Please combine Figures 1 to 6 When the cover plate 300 is installed, the lifting member 121 is pressed down along the z-axis by the pressure of the cover plate 300, and the driving rack 1212 drives the transmission slider 132 through the gear set 131 and the driven rack 1321. Figure 5 14. The locking block 142 is configured to be movable along the direction indicated by the first and second inclined surfaces 1322 and 1411, and the locking block 142 is configured to be movable along the direction indicated by the second and second inclined surfaces 1323 and 1414. When the locking block 142 is movable along the direction indicated by the second and second inclined surfaces 1324 and 1415, the locking block 142 is configured to be movable along the direction indicated by the second and second inclined surfaces 1325 and 1416. When the locking block 142 is movable along the direction indicated by the second and second inclined surfaces 1326 and 1417, the locking block 142 is configured to be movable along the direction indicated by the second and second elastic surfaces 1327 and 1418, and the locking block 142 is configured to be movable along the direction indicated by the second and second elastic surfaces 1328 and 1419. Figure 6 and Figure 7 Status shown.

[0074] Furthermore, in order to ensure that the cover plate 300 can still be conveniently installed on the chassis 200 under the influence of manufacturing and assembly tolerances, Figure 6As shown, a slope surface 1421 may be provided on the top of the block 142. During the process of pressing down the cover 300 for assembly, when the lifting member 121 fails to timely drive the block 142 to avoid the buckle 310 through the intermediate transmission component, the slope surface 1421 will be subjected to the pressure of the buckle 310. At this time, the block 142 will squeeze the second elastic member 144 and stretch the first elastic member 143 to slide toward the lock slider 141, thereby avoiding the buckle 310 and allowing the buckle 310 to continue to descend. When the buckle 310 is lowered into place, the slope surface 1421 is no longer subjected to pressure. At this time, the first elastic member 143 and the second elastic member 144 will restore their deformation to keep the elastic force on the block 142 balanced, that is, the block 142 will slide in the direction away from the lock slider 141, so that the block 142 and the buckle 310 are connected, and the cover 300 is fixed on the chassis 200.

[0075] The above is the scheme of the embodiment corresponding to the attached drawings. In addition, in some other embodiments, the clamping mechanism 140 may only be provided with a clamping block 142 and a first elastic member 143. The first elastic member 143 is also provided between the clamping block 142 and the sliding seat 112 to provide the clamping block 142 with elastic force for sliding unlocking. And the clamping block 142 directly cooperates with the transmission slider 132 through the inclined surface friction. Figure 5 From the perspective, when the transmission slider 132 slides backward along the y-axis, the friction between the inclined surfaces drives the block 142 to slide right along the x-axis and engage with the buckle 310. When the transmission slider 132 slides forward along the y-axis, the block 142 slides left along the x-axis under the elastic force of the first elastic member 143 and releases the engagement with the buckle 310.

[0076] Considering that it is difficult to stably assemble and fix the cover plate 300 on the chassis 200 by a single-point clamping, Figure 1 As shown in , the sliding seats 112 and the clamping mechanisms 140 can be arranged on both sides of the button seat 111 along the direction shown by the x-axis, and the transmission slider 132 is respectively engaged with the clamping mechanisms 140 on both sides through the inclined surface friction. After such arrangement, not only can the cover plate 300 be clamped and fixed with the clamping mechanisms 140 at multiple points through the buckle 310, but also only one button 124 is needed to simultaneously unlock the buckles 310 at multiple points, thereby improving the assembly stability of the cover plate 300 and ensuring convenient operation during disassembly.

[0077] exist Figure 1 In the specific embodiment shown, although only one latching mechanism 140 is provided on each side of the button seat 111, based on the fact that the transmission slider 132 slides in the direction indicated by the y-axis, and the latching mechanism 140 slides in the direction indicated by the x-axis after the transmission slider 132 is frictionally engaged with the inclined surface, even if multiple latching mechanisms 140 are provided on each side of the button seat 111, the same transmission slider 132 can also drive each latching mechanism 140 to slide at the same time.

[0078] Furthermore, if Figure 1 As shown in the figure, a button seat 111 can be set on each of the opposite sides of the chassis 200, and a clamping mechanism 140 can be set on both sides of each button seat 111, so that a multi-point clamping is formed between the cover 300 and the chassis 200 at the opposite sides and close to the end points, the assembly is stable and reliable, and the multiple clamping points on each side are simultaneously controlled to be unlocked by a button 124, so that the cover 300 is easy to disassemble.

[0079] In addition, the transmission slider 132 and the clamping mechanism 140 can further simplify the overall structure without using the inclined surface friction fit. Specifically, the clamping mechanism 140 is only provided with the clamping block 142, and the sliding directions of the transmission slider 132 and the clamping block 142 are both set to the direction shown by the x-axis, and the transmission slider 132 is fixedly connected to the clamping block 142. Figure 2 and 3 On the basis of the embodiment shown in the figure, the helical gear transmission in the gear set 131 is eliminated, and the extension direction of the driven rack 1321 on the transmission slider 132 is adaptively adjusted so that the original sliding direction of the transmission slider 132 along the y-axis is changed to along the x-axis. Figure 5 From the perspective of the perspective, the transmission slider 132 and the block 142 will slide rightward along the x-axis, and the block 142 will engage with the buckle 310. When removing the cover 300, the lifting member 121 rises, driving the transmission slider 132 and the block 142 to slide leftward along the x-axis, and the block 142 will release the engagement with the buckle 310, so that the cover 300 can be lifted up normally and removed.

[0080] In order to prevent the unlocking part of the lifting mechanism 120 from being accidentally touched, causing the cover plate 300 to pop up accidentally, thereby causing risks such as equipment damage, the present application also has an anti-accidental touch design for the lifting mechanism 120 and the clamping mechanism 140. For details, please refer to Figure 1 As shown in the figure, the cover disassembly assembly 100 also includes a switch mechanism 150, which can be movably connected to the base 110. The switch mechanism 150 is used to be detachably limitedly connected to the transmission mechanism 130 to lock or unlock the lifting mechanism 120 and the clamping mechanism 140.

[0081] Specifically, the switch mechanism 150 can use a slidingly arranged latch, a rotatably arranged lock, or other mechanisms to achieve a detachable limited connection with the transmission mechanism 130 .

[0082] After the cover 300 is installed, the switch mechanism 150 is operated to a state of limited connection with the transmission mechanism 130. At this time, if the unlocking component on the lifting mechanism 120 is accidentally touched, the lifting mechanism 120 and the clamping mechanism 140 will not move due to the restriction of the switch mechanism 150 on the movement of the transmission mechanism 130, thereby avoiding the situation where the cover 300 is accidentally opened due to accidental touching.

[0083] When the switch mechanism 150 is accidentally triggered to unlock the transmission mechanism 130, the cover plate 300 will not be accidentally opened because the unlocking component on the lifting mechanism 120 is not triggered. It can be seen that when the cover plate 300 needs to be removed, the switch mechanism 150 needs to be unlocked first, and then the unlocking component on the lifting mechanism 120 needs to be triggered. The probability of accidentally touching the switch mechanism 150 and the unlocking component on the lifting mechanism 120 at the same time is extremely low, so the cover plate 300 can be effectively prevented from being accidentally opened.

[0084] against Figure 1 In the embodiment shown, the cover plate 300 is assembled by multiple snap connections at four end corners. The present application proposes a specific implementation of the switch mechanism 150. First, as shown in FIG. Figure 1 As shown in FIG. 1 , the cover assembly 100 is used to be symmetrically arranged on two opposite side walls of the chassis 200 along the direction shown by the y-axis.

[0085] Please further combine Figures 8 to 10 , Figure 8 FIG. 4 shows a perspective structure of the switch mechanism 150 on the chassis 200. Fig. 9 and Fig.10 The structures of a part of the switch mechanism 150 are shown respectively.

[0086] like Figure 8 As shown in FIG. 1 , the base 110 includes a switch seat 113, and the switch seat 113 is used to be installed on the side wall of the chassis 200 along the direction shown by the x-axis. The switch mechanism 150 includes a rotating block 151, a switch dial block 152 (in Figure 8 The perspective state is shown in the figure, and the entity state can be found in Figure 1 ) and two sets of limiting members 153, the limiting members 153 include a connecting rod 1531, a sliding rod 1532 and a limiting rod 1533.

[0087] like Figure 8 and Fig. 9 As shown in the figure, the rotating block 151 is rotatably arranged on the switch seat 113 relative to the second rotating shaft 1511, and the switch block 152 is used to be slidably arranged on the outside of the chassis 200. The switch block 152 passes through the wall of the chassis 200 and is movably connected to the rotating block 151. The switch block 152 is used to drive the rotating block 151 to rotate when sliding.

[0088] Specifically, the sliding direction of the switch block 152 can be the direction shown by the y-axis, and the switch block 152 and the rotating block 151 can be Fig. 9 A in the middle is movably matched with the thick hole and the thin shaft, so that when the switch block 152 slides left and right along the direction indicated by the y-axis, the rotating block 151 is driven to rotate in the counterclockwise or clockwise direction.

[0089] like Fig. 9 As shown in , two sliding rods 1532 are slidably disposed on both sides of the switch base 113 along the direction shown by the y-axis, and on each side, the connecting rod 1531 is hinged between the sliding rod 1532 and one end of the rotating block 151.

[0090] like Figure 8 and Fig.10 As shown, two limit rods 1533 are respectively arranged on two opposite sides of the two sliding rods 1532, and the two limit rods 1533 are slidably arranged along the direction shown by the x-axis. On each side, the limit rod 1533 is in transmission cooperation with the sliding rod 1532, and a limit portion 133 is arranged at a position opposite to the limit rod 1533 on the transmission mechanism 130, and the limit portion 133 can be, for example, a clamping groove, a clamping hole, a clamping block, etc.

[0091] When the transmission mechanism 130 is locked in position, Fig. 9 In the perspective shown, the switch block 152 is toggled to the right, so that the rotating block 151 rotates in the clockwise direction, and the two sliding rods 1532 slide away from each other under the transmission of their respective connecting rods 1531. Fig.10 From the perspective, the sliding rod 1532 slides to the left, and the left end of the sliding rod 1532 can be frictionally matched with the limiting rod 1533 through the inclined surface. Under the squeezing action of the inclined surface, the limiting rod 1533 slides upward, and the top end extends into the limiting part 133 on the transmission mechanism 130. At this time, the top end of the limiting rod 1533 forms a card connection with the limiting part 133, and the transmission mechanism 130 is restricted and can no longer move.

[0092] like Fig.10 As shown, the base 110 may also include a mounting seat 114 disposed on the side wall of the chassis 200, the limiting rod 1533 is slidably disposed on the mounting seat 114, and a limiting elastic member 1534 is connected between the limiting rod 1533 and the mounting seat 114, and the limiting elastic member 1534 is used to provide an elastic force for the limiting rod 1533 to slide toward the sliding rod 1532, so that Fig. 9 After the switch block 152 is moved to the left in the viewing angle, Fig.10 The sliding rod 1532 slides to the right and releases the friction fit with the limiting rod 1533. The limiting rod 1533 slides downward under the elastic force of the limiting elastic member 1534. The end of the limiting rod 1533 away from the sliding rod 1532 is separated from the limiting portion 133 on the transmission mechanism 130, thereby releasing the movement restriction on the transmission mechanism 130.
