Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of water meters and relates to a foot clamping structure of a meter cover. Background Art
[0002] Among the various components that make up the water meter, the meter cover is one of the indispensable structures. It is mainly locked on the base by screws and nuts, and covers the glass, dial, counter and other components installed on the base to achieve a protective effect.
[0003] Specifically, the watch cover is cylindrical and has through-going ends, the top of which is used for hinged cover plate, and the watch cover is sleeved on the base through the opening at the bottom, and further, a plurality of protruding blocks arranged at intervals along the circumference of the watch cover are integrally injection-molded on the inner wall of the watch cover, and each protruding block is provided with a hexagonal hole for a nut to be clamped, and at the same time, a mounting hole structure is provided on the outer wall of the top of the watch cover corresponding to each hexagonal hole, and during subsequent assembly, the worker only needs to put the screws into each mounting hole in turn, and tighten them down with a screwdriver, so that the screws are respectively screwed and locked with the nuts and the threaded holes on the base, so as to ensure that the watch cover can be firmly positioned on the base.
[0004] But in fact, since the size of the hexagonal hole on the protruding block is fixed, when workers select nuts before assembly, they not only need to match the inner hole of the nut with the outer diameter of the screw, but also need to match the size of the nut with the size of the hexagonal hole, resulting in poor adaptability of the watch cover. Summary of the invention
[0005] The purpose of the utility model is to solve the above problems in the prior art and to propose a foot clamping structure for a watch cover. The technical problem to be solved by the utility model is to improve the adaptability of the watch cover.
[0006] The purpose of the utility model can be achieved through the following technical solutions: a foot structure of a watch cover, the watch cover includes a cylindrical cover body, a mounting hole is opened on the top of the cover body, and it is characterized in that the foot structure includes two blocks whose tops are fixedly connected to the cover body and arranged opposite to each other, a slot is formed between the two blocks, and the slot is located directly below the mounting hole.
[0007] The mounting holes on the cover body are used for inserting screws. The advantage of the foot structure of the present watch cover over the prior art is that two blocks are arranged in the cover body, and the tops of the two blocks are fixedly connected to the inner wall of the cover body and arranged opposite to each other, thereby forming a slot for inserting nuts between the two blocks. On this basis, the present watch cover can be installed with nuts of different models. It should be emphasized that the nuts of different models and sizes targeted by this case refer to nuts with slightly larger outer diameters, which are not applicable to all types of nuts on the market. Specifically, the nuts with slightly larger outer diameters can push the two blocks outward during the process of inserting into the slots, so that the nuts can be normally embedded in the slots, while the side walls of the two blocks (i.e., the slot walls of the slots) can clamp the nuts, thereby ensuring that a wider range of nut models can be selected when the watch cover is assembled, rather than the fixed models specified in the prior art, thereby achieving the effect of ensuring the adaptability of the watch cover and controlling the assembly cost.
[0008] In the above-mentioned foot structure of the watch cover, the two clamping blocks are in the shape of long strips and the opposite side is a clamping surface, and each clamping surface is V-shaped. In the process of inserting the nut into the clamping slot, the existence of the clamping surface can increase the contact area between each clamping block and the nut, thereby achieving the purpose of reducing the pressure and preventing the clamping block from bending or even breaking during the deformation process. Secondly, the existence of the clamping surface can also improve the installation stability of the nut.
[0009] In the above-mentioned foot structure of the watch cover, the upper wall of the cover body has a vertically long protrusion with a hollow interior to form a receiving groove, the mounting hole is located directly above the receiving groove, the lower end of the protrusion is provided with a notch connected to the receiving groove, the tops of the two blocks are fixedly connected to the lower end of the protrusion, and the slot is located directly below the notch. The positions of the mounting hole, the receiving groove, the notch and the slot are in a straight line to ensure the installation of nuts and screws and the subsequent assembly of the watch cover. The presence of the protrusion can ensure that the installation position of the two blocks is lower, so as to ensure that the fixing points of the screw and the nut and the fixing points of the screw and the base are closer during the subsequent installation, preventing the shear force on the screw from acting on the block to cause the block to deform or even break.
[0010] In the above-mentioned foot structure of the watch cover, the bottom wall of the receiving groove has an arc-shaped guide surface along the length direction of the protrusion, which guides the screw during installation, so that the rod of the screw can quickly pass through the notch and be screwed with the nut in the groove.
[0011] In the above-mentioned foot structure of the watch cover, the notch is U-shaped, so that the notch can guide the installation of the screw and avoid the defect that the round hole is difficult to align.
[0012] In the above-mentioned foot structure of the watch cover, there are a plurality of mounting holes arranged at intervals along the circumference of the cover body, and the inner wall of the cover body has a plurality of protrusions located below the mounting holes along the circumference, and the lower end of each protrusion is fixedly connected to two blocks forming the slots. There can be a plurality of slots formed in the cover body, and during subsequent assembly, a plurality of screws and a plurality of nuts can be used to ensure the stability of the cover assembly.
[0013] Compared with the prior art, the foot structure of the watch cover has the following advantages:
[0014] The nut is engaged through the slot formed between the two relatively arranged clamping blocks. For nuts with larger sizes, the two clamping blocks can deform in shape to expand the slot during the insertion process, thereby ensuring that the nut can be clamped while being able to accommodate more types of nuts. This ensures that a wider range of nut models can be selected when the watch cover is assembled, thereby improving the adaptability of the watch cover. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0021] like Figure 1-3As shown, in the foot structure of the watch cover, the watch cover includes a cover body 1 which is cylindrical and has upper and lower ends passing through it, two mounting holes 11 are provided on the edge of the top surface of the cover body 1, and the two mounting holes 11 are arranged at intervals along the circumference of the cover body 1, and two long strip-shaped and vertically arranged protrusions 13 are integrally formed on the inner wall of the cover body 1, the two protrusions 13 correspond to the two mounting holes 11 in position, and each protrusion 13 is hollowed out to form a receiving groove 131 located directly below the mounting hole 11, and a guide surface 1311 in the form of an arc is provided on the inner bottom wall of each receiving groove 131 along the length direction of the protrusion 13.
[0022] Combination Figure 4 A U-shaped notch 132 is provided at the bottom of each protrusion 13, and two strip-shaped and oppositely arranged clamping blocks 12 are provided at the bottom of each protrusion 13 by means of integral injection molding, and a clamping groove 121 located directly below the notch 132 is formed between the two clamping blocks 12. It is worth mentioning that in the two clamping blocks 12 fixed at the bottom of the same protrusion 13, the side surfaces of the two clamping blocks 12 opposite to each other are clamping surfaces 122, and each clamping surface 122 is bent into a V-shape or an L-shape.
[0023] In the scheme disclosed in this embodiment, the number of mounting holes 11 and protrusions 13 is two, and the number of blocks 12 formed on the ground of each protrusion 13 is two groups (that is, the number of blocks 12 is four, and two blocks 12 form a group), but the actual number can be three, four or even more.
[0024] Assembly principle: Before putting the cover body 1 on the base, the worker clamps the nut into the clamping groove 121 and clamps the nut through the clamping surfaces 122 of the two clamping blocks 12, then puts the cover body 1 on the base of the water meter, inserts the screw from the mounting hole 11, and passes through the receiving groove 131, where the guide surface 1311 guides the screw. After passing through the receiving groove 131, the rod of the screw passes through the notch 132 and is screwed to the nut and the threaded hole on the base in turn, while the head of the screw is pressed against the groove wall at the bottom of the receiving groove 131.
[0025] When installing nuts of different sizes and models, workers clamp the nut into the slot 121 by hard clamping. At this time, due to the large size of the nut, the outer wall of the nut applies force to the clamping surface 122 of the two clamping blocks 12, so that the two clamping blocks 12 are slightly bent outward by the extrusion force, so that the volume of the slot 121 is increased. At this time, the nut can be completely clamped into the slot 121. At the same time, the reverse force of the bending deformation of the two clamping blocks 12 clamps the nut through the clamping surface 122, so that the nut is firmly clamped and positioned in the slot 121.
[0026] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
[0027] Although the terminology such as cover body 1, mounting hole 11, clamping block 12, clamping slot 121, clamping surface 122, protrusion 13, receiving slot 131, guide surface 1311, notch 132 is used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for the purpose of more conveniently describing and explaining the essence of the utility model; interpreting them as any additional limitation is contrary to the spirit of the utility model.
