Description

TECHNICAL FIELD

[0001] The utility model relates to fastening device's technical field especially a covering piece clamping device of adjustable interval. BACKGROUND

[0002] Two originally independent objects, in order to be able to assemble into one, need to adopt process to realize connection, for example: welding, screw fastener connection, flange connection, glue bonding etc. Among them, welding, bonding etc. are suitable for one-time connection and do not need to disassemble, 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 external first object and the second object, wherein the first object adopts the form of fixed frame, and the second object adopts the form of movable cover. 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, 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, the first fixed frame is movably provided with a lock rod; 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 screwing 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] Reference 2 to the above application scenario example, see patent CN216783239U, which discloses an easy-to-operate vehicle cover fixing structure, including a longitudinally arranged frame, a latch connected to the frame, and a fixing component. The latch is provided with a mounting seat for arranging the fixing component. The fixing component includes: a screw rod, the mounting seat is provided with a channel for the screw rod to pass through laterally, the channel is provided with multiple limiting ribs that cooperate with the screw rod; a rotating rod, one end of the rotating rod is provided with a hinge joint connected to the screw rod, and the two limiting ribs form an adjustment area, the rotating rod moves back and forth toward the frame in the adjustment area; the other end of the rotating rod is provided with a clamping component, the rotating rod rotates relative to the screw rod so that the clamping component cooperates with the vehicle body, which facilitates installation and reduces movement.

[0005] In existing related documents 1 and 2, the distance can be adjusted vertically to tighten or loosen the cargo cover. However, both have certain drawbacks in use. For example, different vehicle models have different dimensions, specifically variations in the shape and thickness of the cargo cover sidewalls. For instance, if a cargo cover fixing structure (latch) with a smaller spacing is applied to a thicker cargo cover sidewall, it cannot achieve the clamping and fixing function; conversely, if a cargo cover fixing structure (latch) with a larger spacing is applied to a smaller cargo cover sidewall, it will result in a loose fit and failure to clamp. Therefore, in existing technologies, each cargo cover fixing structure (latch) has only one mounting hole (equivalent to a storage slot) along the horizontal direction (generally transverse). Consequently, the position of the clamping block (clamping component) in a single product is unique in the horizontal direction (generally transverse), resulting in a unique distance between it and the cargo cover sidewall during use. This means that a single product can only be used with a specific vehicle. Therefore, multiple products of different sizes need to be customized to meet the needs of different car models, which leads to a significant increase in production and usage costs.

[0027] Preferably, the locking member and the cover plate are provided with matched fixing holes and positioning holes, the fixing holes are located at the middle positions of the open slots, and the positioning holes are symmetrically distributed on the two sides of the open slots.

DETAILED DESCRIPTION

[0046] The utility model will be further explained below in combination with the drawings and specific embodiments. It should be explained that the embodiment is only the specific elaboration of the utility model, and the purpose is to let the person skilled in the art better understand the technical scheme of the utility model, and should not be regarded as the limitation of the utility model.

[0047] In the description of the utility model, it should be explained that, if the terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "internal", "external" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as the limitation of the utility model.

[0048] In the description of the utility model, it should be explained that, unless otherwise explicitly specified and limited, if the terms such as "installation", "connection" and "connection" are broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected;It can be mechanically connected, or it can be electrically connected;It can be directly connected, or indirectly connected through an intermediate medium;It can be the communication inside two elements. For the person skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0049] Example one

[0050] Reference Figures 1-12A distance-adjustable cover clamping device, comprising: a first direction frame 1 and a second direction frame 2, both used for matching a cover 3; preferably, the first direction is longitudinal direction and the second direction is transverse direction, of course, the first direction and the second direction can also refer to other directions, which are not specially limited here. A latch member 4, one end of which is connected to the first direction frame 1 and the other end of which is connected to the second direction frame 2, so that the latch member 4, the first direction frame 1 and the second direction frame 2 are assembled into an integrated whole frame; the cover 3 is generally fixed on the integrated whole frame, so that the cover 3 and the integrated whole frame can realize synchronous movement during disassembly and assembly. When the integrated whole frame with the cover 3 is assembled to the wall of the open carriage (external support 6), it can shield and protect the open carriage. The material of the cover 3 is not limited, which can be made of plastic, leather, metal, rubber, etc. A clamping assembly 5 acts on the integrated whole frame, when the integrated whole frame is placed on the open carriage, although the two have contacted, but in the absence of connection and limiting, it is easy to produce relative displacement, therefore, the integrated whole frame can be clamped to the external support 6 by the clamping assembly 5.

[0051] It needs to be emphasized that the main difference from the prior art is that the latch member 4 has two or more accommodating cavities 41, the clamping assembly 5 is detachably connected to any one of the accommodating cavities 41, and different distances L are formed between each accommodating cavity 41 and the first direction frame 1 / second direction frame 2. When used by the user, the clamping assembly 5 can be selectively assembled into a more suitable accommodating cavity 41 according to the user's own needs (such as the thickness of the vehicle's carriage), so as to match the distance L between the clamping assembly 5 and the external support 6, and ensure that the clamping assembly 5 can stably and reliably clamp the integrated whole frame to the external support 6, eliminating the defects of too large gap and loosening, too small gap and unable to clamp.

[0052] It is worth mentioning that the end of the latch member 4 close to the first direction frame 1 forms a sliding block end 42, the first direction frame 1 is provided with a sliding groove 11, and the sliding block end 42 extends into the sliding groove 11 and forms a sliding fit, so as to adjust the longitudinal (first direction) position of the second direction frame 2 (latch member 4) relative to the first direction frame 1, and meet different needs. After adjustment, the clamping function is realized by the clamping assembly 5.

[0053] Embodiment two

[0054] Reference Figures 1-12 On the basis of the structural scheme of embodiment one, this embodiment provides a more preferred structure, which is as follows:

[0055] I. About accommodating cavity 41: reference Figures 11-12Each of the accommodating cavities 41 comprises a large-diameter section 411 and a small-diameter section 412 in communication, the large-diameter section 411 has a first opening 4111 at one end away from the small-diameter section 412, the small-diameter section 412 has a second opening 4121 at one end away from the large-diameter section 411, and the small-diameter section 412 has a third opening 4122 at a lower end, which is at least partially identical to the large-diameter section 411.

[0056] II. Regarding the clamping assembly 5: referring to Figures 3-6 The clamping assembly 5 comprises at least a connecting rod 51, a pivot shaft 52 assembled on the upper end of the connecting rod 51, and a clamping block 53 sleeved on the connecting rod 51.

[0057] The pivot shaft 52 is installed into the large-diameter section 411 through the first opening 4111 to achieve the installation of the pivot shaft 52. It should be noted that there is a certain play between the pivot shaft 52 and the large-diameter section 411, so that the rotation function can be achieved. On the other hand, the connecting rod 51 can enter the small-diameter section 412 through the second opening 4121 to achieve the installation of the connecting rod 51. Further, the connecting rod 51 and the pivot shaft 52 cooperate to achieve the rotation function, and the connecting rod 51 can switch positions between the second opening 4121 and the third opening 4122.

[0058] Further, the clamping assembly 5 further comprises an operating handle 54, which acts on the clamping block 53 to adjust the relative position relationship between the clamping block 53 and the latch member 4. Due to the limitation of shape, it is difficult for the user to hold and operate the connecting rod 51 or the clamping block 53, so the operating handle 54 is provided to facilitate the user to hold and simply and effectively drive the clamping block 53.

[0059] More specifically, the clamping block 53 is provided with a through hole, and the connecting rod 51 is at least partially arranged in the through hole. It should be noted that the connecting rod 51 and the through hole are in a non-fixed relationship. The operating handle 54 is provided with a rotating hole 541, and a rotating shaft 55 is inserted into the rotating hole 541, so that when the operating handle 54 operates with the axis line 55a of the rotating shaft 55 as the rotation center, the operating handle 54 can rotate independently relative to the clamping block 53; if the operating handle 54 operates with (perpendicular to) the axis line 55a of the non-rotating shaft 55 as the rotation center, the operating handle 54 drives the clamping block 53 to rotate at this time.

[0060] On the other hand, referring to Figures 4-6The rotating shaft 55 is provided with a threaded adjusting hole 551531, the connecting rod 51 is provided with a threaded section 511, and the threaded section 511 is in threaded connection with the threaded adjusting hole 551531. The rotating shaft 55 is horizontally arranged. The length of the threaded section 511 is greater than the depth of the threaded hole. When the operating handle 54 rotates together with the clamping block 53, the threaded connection changes, the actual contact position of the threaded adjusting hole 551531 and the threaded section 511 changes, the clamping block 53 moves close to or away from the latch member 4, and the thickness matching requirement of the external support 6, the frame or the cover 3 is met.

[0061] Embodiment three

[0062] In this embodiment, a more preferred structure of the operating handle 54 is provided, which is specifically as follows: Figure 13 The operating handle 54 is provided with a movable locking buckle 56, which acts on the clamping block 53 to form an interference limiting state 56a and a non-interference state 56b between the locking buckle 56 and the clamping block 53. In the interference limiting state 56a, the movement of the operating handle 54 is limited, and specifically, the operating handle 54 cannot be flipped (with the axis line 55a of the rotating shaft 55 as the rotation center) relative to the clamping block 53. In the non-interference state 56b, the operating handle 54 is released, and specifically, the operating handle 54 can be flipped (with the axis line 55a of the rotating shaft 55 as the rotation center) relative to the clamping block 53. On the other hand, the operating handle 54 can have at least a clamping state and a relaxed state relative to the clamping block 53 (for specific principles, refer to patent document CN117889127A). In the clamping state, the clamping block 53 cannot move to ensure that it continuously and reliably plays a clamping function. In the relaxed state, the clamping block 53 is movable, thereby realizing the subsequent disassembly function.

[0063] The specific working principle is as follows:

[0064] When the locking buckle 56 and the clamping block 53 are in the interference limiting state 56a, the operating handle 54 cannot rotate relative to the clamping block 53, thereby limiting the switching of the operating handle 54 between the clamping state and the relaxed state.

[0065] When the locking buckle 56 and the clamping block 53 are in the non-interference state 56b, the operating handle 54 can rotate relative to the clamping block 53, thereby enabling the operating handle 54 to switch between the clamping state and the relaxed state.

[0066] It is worth mentioning that, referring to Figure 12The inner wall of the small-diameter section 412 is provided with a limiting convex rib 4123, which divides the small-diameter section 412 into a small-diameter receiving section 4124 and a small-diameter working section 4125. The limiting convex rib 4123 is in interference fit with the connecting rod 51, so that when the user operates, a certain force needs to be applied to overcome the resistance, so that the connecting rod 51 can pass through the limiting convex rib 4123 and move between the small-diameter receiving section 4124 and the small-diameter working section 4125. More specifically, when the connecting rod 51 is in the small-diameter receiving section 4124, the clamping block 53 is parallel to the cover 3, and the clamping block 53 will not clamp, so that the operating handle 54 and the clamping assembly 5 are in a receiving mode as a whole; when the connecting rod 51 is in the small-diameter working section 4125, the clamping block 53 is perpendicular to the cover 3, and the clamping block 53 can clamp the overall frame to the external support 6.

[0067] Embodiment four

[0068] In this embodiment, a partial component assembly structure scheme is provided, which is specifically as follows: Figures 9-12 The latch member 4 is provided with an open slot 43, which is communicated with the first opening 4111 of each accommodating cavity 41, and the open slot 43 is detachably assembled with the cover plate 7; when the cover plate 7 is assembled on the open slot 43, the cover plate 7 covers the plurality of first openings 4111 to prevent the pivot shaft 52 from falling off; when disassembly is needed, the cover plate 7 is first disassembled from the open slot 43, and at this time the first opening 4111 of each accommodating cavity 41 is exposed to the outside, so as to facilitate the user to disassemble the pivot shaft 52.

[0069] Preferably, the latch member 4 and the cover plate 7 are provided with matched fixing holes 44 and positioning holes 45, the fixing holes 44 are located at the middle position of the open slot 43, and the positioning holes 45 are symmetrically distributed on both sides of the open slot 43. During assembly, a positioning pin 71 is first inserted into the positioning hole 45, so that the cover plate 7 and the latch member 4 are in pre-positioning connection; then a fastener 72 (preferably a screw) is inserted into the fixing hole 44, so that the cover plate 7 and the latch member 4 are in fixed connection. Under the action of the positioning pin 71, the quick positioning function is realized; one fastener 72 (in the traditional structure, there is no positioning pin 71, and generally two fasteners 72 are needed) is matched with the positioning pin 71, so that the quick fixing effect is realized.

[0070] Preferably, the positioning pin 71 and the cover plate 7 are made of the same material and are integrally formed, so that the production and assembly are more efficient.

[0071] It is worth noting that other technical schemes of the utility model belong to the prior art, and therefore are not described in detail.

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