In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0048] Please also read Figures 1 to 4 , the counterweight block provided in the embodiment of the present application is now described. The counterweight block 1000 includes a base body 1, a cover body 2 and a weight 3. The base body 1 has a receiving cavity 100 for placing the weight 3 therein. One side of the base body 1 is provided with a take-in and put-out port 101 connected to the receiving cavity 100, and the weight 3 can be placed in the receiving cavity 100 through the take-in and put-out port 101. The cover body 2 covers the side of the base body 1 provided with the take-in and put-out port 101, and is used to cover the take-in and put-out port 101, so as to prevent the weight 3 in the receiving cavity 100 from falling out of the base body 1. The number of the weight 3 is at least one, and all the weights 3 are arranged in the receiving cavity 100, playing the main role of counterweight.

[0049] The counterweight block 1000 provided in the present application is different from the existing counterweight blocks. The counterweight block 1000 provided in the present application can adjust the weight of the entire counterweight block 1000 by adjusting the number of weights 3 in the accommodating cavity 100 of the seat body 1. When installing, only the counterweight block 1000 needs to be installed as a whole, and each weight 3 does not need to be installed on the device separately. Of course, multiple counterweight blocks 1000 provided in the present application can be installed on the device at the same time.

[0050] The equipment can be land-based equipment or underwater equipment. Alternatively, the equipment can be mechanical equipment or electronic equipment.

[0051] Specifically, a receiving cavity 100 is provided on the base body 1, and a corresponding number of weights 3 are placed in the receiving cavity 100 according to the counterweight requirement. The weights 3 are placed into the receiving cavity 100 through the taking-in and putting-out port 101 of the base body 1, and then the taking-in and putting-out port 101 is covered with the cover body 2 to prevent the weights 3 in the receiving cavity 100 from falling out, thereby forming a counterweight block 1000 as a whole. The counterweight block 1000 can be installed as a whole on the required equipment, which is convenient to use and easy to carry.

[0052] In another embodiment of the present application, the number of weights 3 placed in the accommodating cavity 100 is determined according to the weight balancing requirement, and may be one, two, three, four or even more.

[0053] In another embodiment of the present application, in order to facilitate the rapid matching of weights 3 of appropriate weights according to the weighting requirements, the weight of each weight 3 can be set to a uniform standard weight, such as, the weight of each weight 3 is 100 grams, or the weight of each weight 3 is 200 grams, etc. Of course, in other embodiments, multiple weights 3 can also be configured to have several different weights, such as, the weight of some weights 3 is 50 grams, the weight of some weights 3 is 100 grams, and the weight of the remaining weights 3 is 200 grams, etc.

[0054] In another embodiment of the present application, the weight 3 can be a metal block or a stone. In addition, the shape of the weight 3 is not limited here, and it can be placed in the accommodating cavity 100.

[0055] In another embodiment of the present application, please refer to Figure 3 and Figure 4 A plurality of partitions 102 are arranged in the base body 1 , and the plurality of partitions 102 divide the accommodating cavity 100 into a plurality of compartments, each of which can be used for placing the weight 3 .

[0056] The accommodating cavity 100 is divided into several compartments by using partitions 102. The compartments of specific sizes can better limit the weights 3 and avoid collision and damage between the weights 3. The weights 3 can also be placed in the compartments at corresponding positions according to different needs, so that the weights 3 are placed in specific positions to meet the equipment's requirements for counterweights, and the application scenarios are more flexible.

[0057] Specifically, the number of the partitions 102 can be two, three, four, five or even more. When the number of the partitions 102 is two, the accommodating chamber 100 is divided into three compartments, and so on. Of course, in other embodiments, the number of the partitions 102 can also be one, and one partition 102 divides the accommodating chamber 100 into two compartments.

[0058] Each partition 102 is arranged at intervals, and two adjacent partitions 102 can be set to the same interval or different intervals. In the present embodiment, some adjacent partitions 102 have the same interval, and some adjacent partitions 102 have different intervals. Thus, three weights 3 can be placed in some compartments, two weights 3 can be placed in some compartments, and one weight 3 can be placed in some compartments.

[0059] In another embodiment of the present application, please continue to refer to Figure 3 and Figure 4, a convex strip 103 is arranged on the inner wall of the compartment. When the weight 3 is placed in the compartment, the convex strip 103 abuts against the outer side of the weight 3, thereby further limiting and fixing the weight 3 to prevent the weight 3 from shaking in the compartment. The convex strips 103 are arranged in pairs on two opposite inner walls of the compartment. The number of convex strips 103 in each compartment is determined according to the number of weights 3 that can be placed in the compartment. For example, when two weights 3 can be placed in the compartment, two pairs of convex strips 103 are correspondingly arranged on the two opposite inner walls of the compartment.

[0060] In another embodiment of the present application, please refer to Figures 1 to 4 The seat body 1 includes a container seat 10, a mounting seat 11 and a fixing assembly 12. The accommodating cavity 100 and the access opening 101 are both opened in the container seat 10, and the cover body 2 covers the container seat 10. The mounting seat 11 is detachably connected to the side of the container seat 10 away from the access opening 101. The fixing assembly 12 is used to realize the installation and fixing of the container seat 10 and the mounting seat 11.

[0061] The mounting seat 11, the container seat 10 and the cover body 2 are stacked in sequence to form a whole.

[0062] When the counterweight block 1000 provided in the present application needs to be installed on a device, the mounting seat 11 is first fixed to the device, and after the corresponding number of weights 3 are configured in the container seat 10, the cover body 2 and the container seat 10 are covered to form a combination, and finally the combination is fixed to the mounting seat 11 through the fixing component 12.

[0063] Therefore, when the weight requirement of the equipment changes, there is no need to remove the mounting seat 11 from the equipment. Instead, the container seat 10 only needs to be removed from the mounting seat 11 and the weight 3 in the container seat 10 needs to be replaced.

[0064] In another embodiment of the present application, the container seat 10 is specifically a structure with a hollow interior and an opening on one side, the hollow interior forms the aforementioned accommodating cavity 100, and the aforementioned partitions 102 are arranged in parallel inside the container seat 10, that is, a plurality of compartments are formed inside the container seat 10. The opening on one side of the container seat 10 forms the aforementioned access opening 101.

[0065] In another embodiment of the present application, please refer to Figure 3 and Figure 4 A clamping member 104 is provided on the side adjacent to the access opening 101 of the container seat 10, and one side of the clamping member 104 is fixed to the container seat 10. A clamping slot 20 is provided on the cover body 2. When the cover body 2 is covered on the access opening 101 of the container seat 10, the other side of the clamping member 104 is clamped into the clamping slot 20 of the cover body 2, thereby realizing the clamping fixation of the container seat 10 and the cover body 2. In addition, the container seat 10 and the cover body 2 can also be fastened by fasteners to enhance the installation reliability. The fasteners can specifically be bolts.

[0066] In another embodiment of the present application, please continue to refer to Figure 3 and Figure 4 The cover 2 is provided with a water hole 21, which is used to fill or drain water from the container seat 10. Therefore, the counterweight block 1000 provided in the embodiment of the present application can be used not only on land equipment but also on underwater equipment. When the counterweight block 1000 is used on underwater equipment, when entering water, the container seat 10 can be quickly filled with water through the water hole 21 to avoid buoyancy affecting the counterweight effect. After leaving the water, the water in the container seat 10 can be quickly discharged through the water hole 21.

[0067] In another embodiment of the present application, please refer to Figure 1 and Figure 2 The fixing assembly 12 includes a buckle 120 , which is disposed on the container seat 10 . A buckle groove 110 is correspondingly formed on the mounting seat 11 , and the buckle 120 is buckled with the buckle groove 110 .

[0068] The mounting seat 11 and the container seat 10 are fixedly mounted by means of the buckling member 120 and the buckling groove 110 . The buckling member 120 only needs to be buckled into the buckling groove 110 . The operation is simple and the installation efficiency is high.

[0069] In another embodiment of the present application, please refer to Figure 5 and Figure 6 The fastener 120 includes a connecting portion 1200 and an abutting portion 1201, and the two ends of the connecting portion 1200 are respectively connected to the container seat 10 and the abutting portion 1201. The buckle groove 110 includes an inserting groove 1100 and a limiting groove 1101 that are interconnected. The fastener 120 can slide between the inserting groove 1100 and the limiting groove 1101. The inserting groove 1100 can be provided for the connecting portion 1200 and the abutting portion 1201 to pass through, and the limiting groove 1101 is only provided for the connecting portion 1200 to pass through, so that the fastener 120 can be limited in the buckle groove 110.

[0070] When installing and fixing the container seat 10 and the mounting seat 11, first move the container seat 10 close to the mounting seat 11, and place the abutting portion 1201 and the connecting portion 1200 of the buckle into the insertion groove 1100 in sequence until the container seat 10 abuts against the mounting seat 11, push the container seat 10 sideways to make the buckle slide to the limiting groove 1101, at this time, the connecting portion 1200 is inserted into the limiting groove 1101, and the abutting portion 1201 is stuck in the limiting groove 1101 (that is, in the stacking direction of the container seat 10 and the mounting seat 11, the abutting portion 1201 abuts against the groove wall of the limiting groove 1101), thereby realizing the buckle connection between the container seat 10 and the mounting seat 11.

[0071] Specifically, the connecting portion 1200 is vertically connected to the abutting portion 1201, presenting an inverted "L"-shaped structure. The length of the buckle groove 110 is greater than the length of the buckle member 120. Along the length direction of the buckle groove 110, the buckle groove 110 is divided into an insertion groove 1100 and a limiting groove 1101. The length of the insertion groove 1100 is at least the length of a buckle member 120 to ensure that the buckle member 120 can pass through the insertion groove 1100. A blocking piece 1102 is provided on the end of the limiting groove 1101 close to the container seat 10. The width of the blocking piece 1102 is less than the width of the buckle groove 110, so that a gap is formed between the blocking piece 1102 and the groove wall. The width of the gap is greater than or equal to the width of the connecting portion 1200 and less than the width of the connecting portion 1200. Therefore, after the fastener 120 is inserted into the insertion groove 1100, when the latch is slid, the connecting portion 1200 can move in the gap of the limiting groove 1101, and the abutting portion 1201 moves on the side of the blocking piece 1102 away from the container seat 10, so that the fastener 120 is limited in the fastening groove 110.

[0072] In another embodiment of the present application, please refer to Figure 2 and Figure 5 The number of the buckle members 120 is multiple, and the number and position of the buckle slots 110 are set correspondingly. In the embodiment of the present application, the number of the buckle members 120 is four, which are evenly distributed on the container seat 10.

[0073] In another embodiment of the present application, please refer to Figure 2 and Figure 7 The fixing assembly 12 further includes a locking structure 121 , which is used to limit the buckle from sliding between the insertion groove 1100 and the limiting groove 1101 .

[0074] After the container seat 10 and the mounting seat 11 are buckled together, the locking structure 121 is used to limit the sliding of the buckle 120 between the insertion groove 1100 and the limit groove 1101, which can prevent the container seat 10 and the mounting seat 11 from moving relative to each other and causing the buckle to slide into the insertion groove 1100, thereby causing the container seat 10 and the mounting seat 11 to accidentally disengage, thereby ensuring that the container seat 10 is firmly installed on the mounting seat 11.

[0075] In another embodiment of the present application, please refer to Figure 2 and Figure 7 The locking structure 121 includes a locking block 1210 , which is slidably arranged on the container seat 10 along the connecting line direction between the container seat 10 and the mounting seat 11 . The mounting seat 11 is provided with a locking groove 111 , and a portion of the locking block 1210 can be slidably placed in the locking groove 111 .

[0076] By providing a locking block 1210 that can only slide along the line connecting the container seat 10 and the mounting seat 11, when locking is required, a part of the locking block 1210 is slid into the locking groove 111. Since the locking block 1210 cannot slide relative to the locking groove 111 along the line connecting the insertion groove 1100 and the limiting groove 1101, the container seat 10 and the mounting seat 11 cannot move relative to each other along the line connecting the insertion groove 1100 and the limiting groove 1101. The buckle connection between the buckle and the slot 20 and the matching connection between the locking block 1210 and the locking groove 111 make the installation and fixation between the container seat 10 and the mounting seat 11 more reliable.

[0077] In another embodiment of the present application, please refer to Figure 7 The side of the container seat 10 is provided with an installation groove 105, and the installation groove 105 is for the installation of the lock block 1210. The lock block 1210 is provided with a safety lock 122, and the side of the safety lock 122 close to the container seat 10 is provided with a lock buckle groove 1222, and the groove wall of the installation groove 105 is provided with a lock buckle 123, and the lock buckle 123 is buckled with the lock buckle groove 1222 to limit the lock block 1210 from sliding out of the lock groove 111, so as to prevent the lock block 1210 from being accidentally pushed and the container seat 10 and the installation seat 11 from being separated.

[0078] In another embodiment of the present application, please refer to Figure 7 and Figure 8 The safety lock 122 includes a lock catch portion 1220 and a toggle portion 1221 that are integrally connected. The lock catch portion 1220 is located on a side close to the container seat 10, and correspondingly, the toggle portion 1221 is located on a side away from the container seat 10. The lock catch groove 1222 is provided on the side of the lock catch portion 1220 close to the container seat 10, and the lock catch groove 1222 is "L"-shaped. The lock catch groove 1222 is opened through the connection direction of the container seat 10 and the mounting seat 11, so that the lock catch 123 can be inserted into the lock catch groove 1222, and by sliding the safety lock 122, the top of the lock catch 123 abuts against the groove wall of the lock catch groove 1222 and is restricted in the lock catch groove 1222, thereby restricting the lock block 1210 from sliding out of the lock groove 111. The locking block 1210 is provided with a shifting groove 124, through which the shifting portion 1221 can pass, but the locking portion 1220 is restricted from passing therethrough, and the shifting groove 124 is longer than the shifting portion 1221, so that the shifting portion 1221 can slide left and right in the shifting groove 124, so that the locking portion 123 can slide in the locking groove 1222, so as to make the locking portion 123 and the locking portion 1220 buckled or release the buckled state.

[0079] In other embodiments, a mounting groove 105 is provided on the side of the container seat 10, and the mounting groove 105 is provided for the locking block 1210 to be installed. An elastic member (not shown in the figure) is provided between the groove wall of the mounting groove 105 and the locking block 1210, and the expansion and contraction direction of the elastic member is the same as the stacking direction of the container seat 10 and the mounting seat 11 (i.e., the connection direction of the container seat 10 and the mounting seat 11). Under normal circumstances, the locking block 1210 is located in the mounting groove 105 and the locking groove 111 at the same time. When the container seat 10 and the mounting seat 11 need to be separated, the locking block 1210 is pressed until the locking block 1210 is completely separated from the locking groove 111. With this structure, the locking block 1210 can be fixed in the mounting groove 105, and it is not easy to be lost. After pressing the locking block 1210, the locking block 1210 can be automatically restored to the locking groove 111 through the elastic member.

[0083] In another embodiment of the present application, the adhesive layer 1120 is formed by coating strong glue on the mounting side 112 of the mounting seat 11 .

[0084] In another embodiment of the present application, please refer to Figure 1 and Figure 2 The side of the seat body 1 facing away from the cover body 2 is set as the installation side 112, specifically, the side of the mounting seat 11 facing away from the cover body 2 is the installation side 112, and an adjustment block 1121 is detachably provided on the installation side 112, and the adjustment block 1121 is used to adjust the shape of the installation side 112.

[0085] A detachable and replaceable adjustment block 1121 is provided on the installation side 112, so that the adjustment block 1121 of corresponding shape and size can be configured according to the shape and size of the corresponding installation surface of the device, so that the counterweight block 1000 can be better fitted to the installation surface of the device for installation.

[0086] In another embodiment of the present application, the mounting side 112 is provided with two opposite adjustment slots, and an adjustment block 1121 is installed on each adjustment slot, so that the two adjustment blocks 1121 cooperate with the mounting side 112 to form a mounting surface of the counterweight 1000. An adhesive layer is provided on the mounting surface for bonding and fixing with the device.

[0087] When the installation surface of the device is a plane, the two adjustment blocks 1121 are set as rectangular blocks. At this time, the installation surface of the counterweight block 1000 is a plane, so that it can fit well with the installation surface of the device.

[0088] When the installation surface of the device is a curved surface, the two adjustment blocks 1121 are set as trapezoidal blocks, and the surface of the adjustment block 1121 (the side facing away from the mounting base 11) is a curved surface. By adjusting the height of the side of the two adjustment blocks 1121 that are away from each other, curved surfaces with different degrees of curvature can be adjusted so that they can fit well with the installation surface of the device.

[0089] In another embodiment of the present application, the adjustment block 1121 is elastic, which can enable the adjustment block 1121 to better fit the surface of the device on the one hand, and on the other hand, enables the counterweight block 1000 provided in the present application to be used on devices with similar mounting surface curvature without replacing the adjustment block 1121.

[0090] The present application also provides an underwater photography device, which includes a body 2000 and a lens 3000 installed on the body 2000. The lens 3000 is provided with a counterweight block 1000 provided in an embodiment of the present application. The counterweight block 1000 is used to balance the buoyancy center of gravity of the lens 3000 so that the underwater photography device can maintain a horizontal state underwater.

[0091] The underwater photographic equipment provided in the present application adopts the counterweight block 1000 provided in the present application, because the lens part of the underwater photographic equipment is tilted up due to the influence of buoyancy when the underwater photographic equipment is used underwater. The weight of the counterweight block 1000 can be adjusted according to the counterweight requirement, and the counterweight block 1000 is installed at a suitable position of the lens 3000. This can balance the buoyancy center of gravity of the underwater photographic equipment, so that the underwater photographic equipment can maintain a horizontal state underwater, and the counterweight requirement of the underwater photographic equipment can be quickly and conveniently solved.

[0092] In another embodiment of the present application, please refer to Figures 9 and 10 The device is specifically a wide-angle photographic device. Since the lens barrel of the wide-angle photographic device is large in size, the buoyancy is greater underwater, which will cause the balance to be destroyed, causing the lens of the underwater photographic device to tilt, thereby affecting normal shooting. Therefore, when the wide-angle photographic device is used underwater, by installing the counterweight block 1000 provided by the present application at the lens of the underwater photographic device, the lens of the underwater photographic device can be balanced, so that the underwater photographic device can be kept balanced.

[0093] When in use, the mounting seat 11 is fixed to a suitable position of the underwater photographic equipment (such as the lens barrel) using the adhesive layer 1120, and weights 3 of a suitable number and weight are placed in the container seat 10 according to the counterweight requirements of the underwater photographic equipment. The cover body 2 is covered with the container seat 10, and then the container seat 10 is fixed to the mounting seat 11 by the fixing assembly 12. The buoyancy center of gravity of the underwater photographic equipment can be adjusted by the counterweight block 1000 to prevent the lens part of the underwater photographic equipment from tilting up when the underwater photographic equipment is used underwater, so that the underwater photographic equipment is in an ideal balanced state underwater.

[0094] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
