[0002] Two originally independent objects, in order to be able to be assembled into one, need to adopt process to realize connection, for example: welding, screw fastener connection, flange connection, glue bonding and the like. Among them, welding, bonding and the like are suitable for one-time connection and do not need to be disassembled, and the use scene is less. Other connection methods also have their respective limitations. The application scenario in the present application needs to connect the first object and the second object outside, wherein the first object adopts a fixed frame form, and the second object adopts a movable cover form. A third-party device applies pressure to the fixed frame and the movable cover, so that the two can be reliably pressed together, thereby providing shielding protection for the originally open space in the fixed frame through the movable cover. In other cases, the pressure is removed by the third-party device, thereby forming a gap between the fixed frame and the movable cover and mutually loosening, and then the movable cover can be moved relative to the fixed frame and stored, and at the same time the space in the fixed frame is exposed.

[0003] Related document 1 of the above application scenario example, refer to patent CN217415587U, discloses a adjustable support assembly, including carriage and fixed cover plate, further comprising: first fixed frame, provided at the bottom of the fixed cover plate, a lock rod is movably provided on the first fixed frame; side type frame, fixed on the inner side boundary of the carriage; second fixed frame, including a stop position clamped on the side type frame, and a pressing position matched with the first fixed frame, the stop position cooperates with the side type frame profile and limits the vertical movement of the second fixed frame, the pressing position is provided with a strip-shaped hole for the lock rod to pass through, the lock rod is pressed on the carriage with the fixed cover plate and passes through the strip-shaped hole; fixed assembly, the fixed assembly is used for being screwed on the lock rod after the lock rod passes through the strip-shaped hole, so as to press the first fixed frame on the second fixed frame, facilitating the assembly of the fixed cover plate.

[0004] The related literature 2 of the above application scenario example, refer to the patent CN216783239U, discloses a convenient operation's carriage cover fixing structure, including the frame that sets up longitudinally, with the lock latch connected with the frame, and the fixed assembly, the lock latch is equipped with the mounting seat for the fixed assembly arrangement, the fixed assembly includes: screw rod, the mounting seat is equipped with the channel for the screw rod transversely to set in it, the channel is equipped with a plurality of with screw rod cooperation's limiting rib; The rotating rod, one end of the rotating rod is equipped with the hinge joint connected with the screw rod, the two limiting rib between constitutes the adjusting area, the rotating rod moves in the adjusting area towards the frame before and after;The rotating rod other end is equipped with the clamping assembly, the rotating rod rotates relative to the screw rod, so that the clamping assembly cooperates with the carriage, facilitates installation and reduces the shift.

[0005] The related literature 1 and the related literature 2 in the prior art can be adjusted in the vertical direction to tighten or release the carriage cover, but there are certain defects in the use process, for example: different vehicle models have different vehicle sizes, specifically, the shape, thickness and other sizes of the carriage side wall have certain differences.For example, if the carriage cover fixing structure product (lock latch) with a smaller distance is applied to a thicker carriage side wall, the clamping and fixing functions cannot be realized;if the carriage cover fixing structure product (lock latch) with a larger distance is applied to a smaller carriage side wall, there will be defects such as loose fit and inability to clamp. Therefore, in the prior art, each carriage cover fixing structure product (lock latch) has only one mounting hole (equivalent to a receiving groove) along the horizontal direction (generally transverse), so the position of the clamping block (clamping assembly) in the horizontal direction (generally transverse) in a single product is unique, which leads to a unique distance between the clamping block and the carriage side wall during use, thereby causing a single product to be suitable for use only on a specific vehicle. Therefore, multiple products of different sizes need to be customized to meet the needs of different vehicle models, resulting in a significant increase in production and use costs.

[0006] On the other hand, assuming that multiple mounting holes are provided in a single product, but if the mounting holes need to be switched, the relevant accessories need to be disassembled and assembled, which is very inconvenient to operate, and repeated disassembly and assembly can easily lead to a decrease in fitting accuracy, affecting the reliability of use.

[0048] Example one

[0049] Reference Figures 1-11The application discloses a clamping device for a cover with a dismount-free gear shifting function, a first direction frame 11 and a second direction frame 12, which are used for matching a cover 13; a latch member 14, one end of which is connected to the first direction frame 11 and the other end of which is connected to the second direction frame 12, so that the latch member 14, the first direction frame 11 and the second direction frame 12 are assembled into an integrated whole frame 1; the cover 13 is generally fixed on the whole frame 1, so that the cover 13 and the whole frame 1 can realize synchronous movement in the process of dismounting. When the whole frame 1 with the cover 13 is assembled to an open carriage wall (an external support 4), the open carriage can be shielded and protected. The material of the cover 13 is not limited, for example, the cover 13 can be made of plastic, leather, metal or rubber. A clamping assembly 2 is used for clamping the whole frame 1 to the external support 4. When the whole frame 1 is placed on the open carriage, although the whole frame 1 and the external support 4 have contacted, the relative displacement is prone to occurring in the absence of connection and limiting, so the clamping assembly 2 can clamp the whole frame 1 to the external support 4.

[0050] It is particularly emphasized that the application is not limited to the embodiments described herein Figures 1-6 The difference between the application and the prior art mainly lies in that the application further comprises a gear pin assembly 3 which is connected with the clamping assembly 2; the latch member 14 is provided with two or more gear slots 141 and a gear shifting channel slot 142 along the second direction, the gear shifting channel slot 142 is communicated with each gear slot 141 respectively, and each gear slot 141 has different distances L with the first direction frame 11 or / and the second direction frame 12. In use, the user can selectively assemble the clamping assembly 2 into a more suitable gear slot 141 according to the own demand (for example, the thickness of the carriage of the own vehicle), so as to match the distance L between the clamping assembly 2 and the external support 4, ensure that the clamping assembly 2 can stably and reliably clamp the whole frame 1 to the external support 4, and eliminate the defects of too large clearance and too small clearance.

[0051] On the other hand, it is worth mentioning that the gear pin assembly 3 can move along the gear shifting channel slot 142 together with the clamping assembly 2, and after the movement, the gear pin assembly 3 can enter any one of the gear slots 141. It should be understood that the gear pin assembly 3 can be moved and switched from one gear slot 141 to another gear slot 141 through the gear shifting channel slot 142 without dismounting, the operation is more convenient, and the assembly precision between parts is ensured, so that the whole product has a continuous and reliable function performance.

[0052] It is particularly emphasized that the application is not limited to the embodiments described herein Figure 11, preferably, the shift passage slot 142 is in the shape of "T" in the cross section along the first direction, and the shift slot 141 penetrates the shift passage slot 142 along the first direction.

[0053] Embodiment Two

[0054] On the basis of the structural scheme of Embodiment One, this embodiment provides a more preferred structure, which is as follows:

[0055] I. Regarding the shift pin assembly 3: the shift pin assembly 3 comprises a shift-on pin member 31 and a movable collar 32; wherein the movable collar 32 is movably arranged in the shift passage slot 142, the movable collar 32 is sleeved on the shift-on pin member 31, and the movable collar 32 is connected with the clamping assembly 2; the shift-on pin member 31 can move along the shift passage slot 142 together with the movable collar 32, and the shift-on pin member 31 can enter or exit any one of the shift slots 141. It can be understood that the cooperation of the shift-on pin member 31 and the shift slot 141 mainly plays a shift-on role; the movable collar 32 plays a role of structural series connection and support with the shift-on pin member 31, and the movable collar 32 can play a role of movement guidance and preventing the shift-on pin member 31 from deviating from the normal working area.

[0056] II. Regarding the clamping assembly 2: referring to Figure 4 , the clamping assembly 2 at least comprises a connecting rod 21, a connecting pin member 22 assembled on the upper end of the connecting rod 21, and a clamping block 23 sleeved on the connecting rod 21; wherein the connecting rod 21 is provided with a connecting hole 33 matched with the movable collar 32, and the connecting shaft member is assembled into the connecting hole 33, so that the connecting rod 21 is connected with the movable collar 32 through the connecting pin member 22.

[0057] The working principle of the clamping assembly 2 is as follows: referring to Figures 1-3 , when the clamping assembly 2 is moved along the second direction, the connecting pin member 22 contacts with the movable collar 32 and forms a transmission cooperation, so that the clamping assembly 2 drives the shift-on pin member 31 to move along the second direction. On the other hand, referring to Figure 5 , when a rotating force is applied to the connecting rod 21 (with the axis line of the connecting shaft member as the rotating force center), the connecting rod 21 will rotate alone (with the axis line of the connecting shaft member as the rotating center) relative to the movable collar 32 (the connecting shaft member). At the same time, the clamping block 23 can clamp the overall frame 1 to the external support 4.

[0058] III. Operation mode: referring to Figures 4-9The clamping block 23 is provided with a through hole 231, and the connecting rod 21 is at least partially arranged in the through hole 231. It should be noted that the connecting rod 21 and the through hole 231 are in a non-fixed relationship. The clamping assembly 2 further comprises an operation handle 25, the operation handle 25 is provided with a rotating hole 251, the rotating hole 251 is arranged in a rotating shaft 26, and the rotating shaft 26 is provided with a threaded adjusting hole 261. The connecting rod 21 is provided with a threaded section 211, the threaded section 211 is in threaded connection with the threaded adjusting hole 261. The rotating shaft 26 is arranged in a horizontal manner. The length of the threaded section 211 is greater than the depth of the threaded hole.

[0059] With reference to Figure 9 , when the operation handle 25 is operated with the axis of the rotating shaft 26 as the rotation center, the operation handle 25 can be independently rotated relative to the clamping block 23. With reference to Figure 8 , when the operation handle 25 is operated with the axis of the rotating shaft 26 as the rotation center, the operation handle 25 drives the clamping block 23 (the connecting rod 21) to rotate together.

[0060] On the other hand, when the operation handle 25 drives the clamping block 23 to rotate together, the threaded connection relationship will change. With the latch member 14 as a fixed reference, the actual contact position of the threaded adjusting hole 261 and the threaded section 211 changes, so that the clamping block 23 approaches or moves away from the latch member 14, so as to meet the thickness size matching requirements of different external supports 4 or frames or coverings 13.

[0061] In addition, with reference to Figure 7 , the different cooperation degrees between the threaded section 211 and the threaded adjusting hole 261 can change the distance between the clamping block 23 and the latch member 14 (the covering 13) in the third direction, so as to adapt to different size requirements.

[0062] Embodiment three

[0063] With reference to Figure 5 , Figure 10 , regarding the optional structure scheme of the latch member 14 in the present disclosure, the latch member 14 is further provided with a receiving groove 143 distributed along the first direction, the receiving groove 143 is in communication with the shifting channel groove 142, and the inner wall of the receiving groove 143 is provided with a limiting rib 1431. More specifically, the connecting pin member 22 is fixedly connected with the movable collar 32, and the connecting pin member 22 and the connecting rod 21 form a gap cooperation, so that the connecting rod 21 can be independently rotated relative to the movable collar 32 with the axis of the connecting pin member 22 as the rotation center, thereby enabling the connecting rod 21 to enter or exit the receiving groove 143.

[0064] As mentioned in Embodiment Two, when the operating handle 25 is operated with the axis of the non-rotating shaft 26 as the rotation center, the operating handle 25 rotates the connecting rod 21 together, and the connecting rod 21 can enter the receiving groove 143, at this time, the limiting rib 1431 can abut against the connecting rod 21 and play a limiting role to prevent the connecting rod 21 from falling off, at this time, the clamping block 23 (operating handle 25) is parallel to the cover 13, and the clamping block 23 will not play a clamping role, so that the operating handle 25 and the clamping assembly 2 as a whole are in a storage form.

[0065] If the clamping assembly 2 needs to play a clamping role, when the operating handle 25 is controlled again to be reversely rotated with the axis of the non-rotating shaft 26 as the rotation center, the connecting rod 21 overcomes the resistance of the limiting rib 1431 and leaves the receiving groove 143, so that the subsequent operation of the clamping block 23 can realize the function of clamping the overall frame 1 to the external support 4.

[0066] Optionally, the receiving groove 143 is arranged along a first direction, and the blocking groove 141 is arranged along a third direction. Preferably, taking the drawings as an example, the first direction is a longitudinal direction, the second direction is a transverse direction, and the third direction is a vertical direction. Of course, the first direction, the second direction and the third direction can also refer to other directions, which are not specially limited herein.

[0067] Embodiment Four

[0068] In this embodiment, referring to Figures 4-10 , the preferred component structure scheme of the blocking pin member 31 and the connecting pin member 22 in the present disclosure is provided, which is specifically as follows:

[0069] I. The blocking pin member 31 comprises a blocking screw 311 and a blocking nut 312, the blocking screw 311 is screwed through the movable collar 32 and is threadedly connected with the blocking nut 312, and the sizes of the screw head of the blocking screw 311 and the blocking nut 312 are both greater than the opening size of the side wall of the shifting channel groove 142, so that the blocking screw 311 and the blocking nut 312 are limitedly matched with the side wall of the shifting channel groove 142.

[0070] II. The connecting pin member 22 comprises a connecting screw 221 and a connecting nut 222, the connecting screw 221 is screwed through the connecting hole 33 and is threadedly connected with the connecting nut 222, and the sizes of the screw head of the connecting screw 221 and the connecting nut 222 are both greater than the hole diameter size of the connecting hole 33, so that the connecting screw 221 and the connecting nut 222 are limitedly matched with the side wall of the movable collar 32.

[0071] It is worth noting that other technical schemes of the present application are all prior art, and thus are not described herein.

[0072] The above merely describes preferred embodiments of the present application, and it should be noted that, for those skilled in the art, without departing from the concept of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as falling within the scope of the present application.
