Description

Technical Field

[0001] This application relates to the technical field of knockout holes, and particularly to a housing and a thermostat with a knockout hole structure. Background Art

[0002] In the fields of industrial design and electronic product manufacturing, structural design often needs to consider the diversity and adaptability of the installation environment. To ensure that the device can flexibly respond to different installation positions and wire outlet requirements, referring to Figure 1 , designers usually set multiple knockout holes at the four peripheral edges of the product. These knockout holes allow cables to enter and exit from different directions, increasing the flexibility of the design to meet the wiring requirements in various installation scenarios.

[0003] However, such a design also brings certain problems. Especially in precision devices such as thermostats, the wire outlet requirements are usually relatively fixed, perhaps limited to 1 - 2 specific directions. This means that the other unused knockout holes will not only not be utilized but may instead become aesthetic flaws on the appearance, affecting the overall beauty of the product. Utility Model Content

[0004] For this reason, this application provides a housing with a knockout hole structure to solve the problem that the unused knockout holes in the prior art affect the product appearance.

[0005] To achieve the above object, this application provides the following technical solutions:

[0006] A housing with a knockout hole structure, wherein the inner wall of the housing is made into a groove at a position corresponding to the preset knockout hole contour line, and the outer wall of the housing in the area corresponding to this groove maintains its original complete form. This groove serves as a weak area of the housing to form the knockout hole structure.

[0007] Optionally, the groove is a V-shaped groove.

[0008] Optionally, the groove is formed by a glue-reducing treatment process.

[0009] Optionally, the knockout hole contour line is located at the lower part of the side surface of the housing and is connected to the bottom surface of the housing. A relief hole for facilitating the insertion of a tool into the housing to remove the knockout hole structure is provided in the corresponding adjacent area of the bottom surface of the housing.

[0010] Optionally, both ends of the relief hole are aligned with both ends of the corresponding knockout hole structure.

[0011] Optionally, the knockout hole structures are provided on multiple side surfaces of the housing.

[0012] Optionally, the minimum distance between the bottom of the groove and the outer surface of the housing is 0.8 mm.

[0013] A thermostat, the housing of which adopts the housing with knock-out hole structure described above.

[0014] Optionally, a knock-out hole structure is provided at one place on each of two adjacent sides of the housing of the thermostat.

[0015] Compared with the prior art, the present application has at least the following beneficial effects:

[0016] 1. While a groove is provided inside the housing, the outer surface of the housing corresponding to the knock-out hole structure can be ensured to be flat (maintaining the original complete form) without forming a hollow structure, so that the position where the product does not need to route wires can maintain a good appearance surface, avoiding affecting the appearance of the product.

[0017] 2. The design of the avoidance hole makes it more convenient to insert one end of a tool such as a long-nose pliers or a side-cutting pliers into the housing, and then remove the knock-out hole structure at the corresponding position of the groove. Description of the Drawings

[0024] The following further details the present application through specific embodiments in conjunction with the drawings.

[0025] In the description of the present application: Unless otherwise specified, "a plurality of" means two or more. Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0026] In this application, terms such as "upper", "lower", "left", "right", "middle", etc. are usually used to indicate the general relative position for intuitive understanding with reference to the attached drawings, rather than absolute limitations on the position relationship in the actual product.

[0027] Embodiment 1

[0028] A housing with a knock-out hole structure 2, referring to Figure 2 And Figure 3 , the material of the housing is selected from materials such as PC material, ABS material or acrylic material that can meet the injection molding requirements, and an integral injection molding process is adopted. In this embodiment, the housing is of a rectangular or square structure, and a groove 1 is formed at a position on the inner wall of the housing corresponding to the preset knock-out hole contour line. Then, this groove 1 serves as a weak area of the housing to form a knock-out hole structure 2.

[0029] Since the housing in this embodiment adopts an integral injection molding process, therefore, the groove 1 is formed by a process of local glue reduction. It should be noted during the processing that only the inner wall of the housing is locally reduced in glue, ensuring that the area of the outer wall of the housing corresponding to this groove 1 maintains its original complete form, making its outer surface smooth without holes, and appearing as a whole from the outside, improving the appearance quality of the product and being different from the outer wall hollow structure of the prior art.

[0030] Specifically, the groove 1 is of a V-shaped groove 1 structure. V-shaped means that the width of the groove 1 gradually decreases from the groove opening to the groove bottom, the two side groove walls can be asymmetric, and the groove bottom does not have to be a strictly sharp shape, and can even be a trapezoidal structure with a flat groove bottom, as long as it is ensured that the width of the groove opening is greater than the width of the groove bottom, making the position of the housing corresponding to the groove 1 weak and easy to remove.

[0031] Among them, the minimum distance between the groove bottom of the groove 1 and the outer surface of the housing is 0.8 mm, that is, during the injection molding process, the part of the housing corresponding to the groove 1 is ensured to have a glue thickness of about 0.8 mm, which is not only convenient to remove this part during use, but also can prevent the accidental detachment of the knock-out hole structure 2 part.

[0032] Furthermore, the knock-out hole contour line is set at the lower part of the side of the housing and is connected to the bottom surface of the housing, and an avoidance hole 3 is provided in the adjacent area corresponding to the bottom surface of the housing to facilitate a tool (such as a pointed-nose pliers or a side-cutting pliers, etc.) to extend into the housing to remove the knock-out hole structure 2.

[0033] Specifically, the avoidance hole 3 penetrates the lower surface of the housing, and the tool can extend one end in from the bottom of the product. Through this setting method, not only is it convenient to remove the knock-out hole structure 2, but also since the position of the knock-out hole structure 2 cannot be seen from the outside of the product, the setting of the avoidance hole 3 plays a positioning effect, and the position of the knock-out hole structure 2 can be intuitively known.

[0034] To improve the accuracy of the avoidance hole 3, the length of the avoidance hole 3 is set to be consistent with the length of the knock-out hole structure 2, and the two ends of the avoidance hole 3 are aligned with the two ends of the knock-out hole structure 2 to more accurately remove the knock-out hole structure 2.

[0035] In addition to the knockout hole structure 2 being set at the bottom of the side of the shell in this embodiment, in other embodiments, the knockout hole structure 2 can also be set at the bottom of the shell or the middle of a side according to actual conditions. Correspondingly, the avoidance hole 3 is set at the position that interfaces with the knockout hole structure 2, as long as it is convenient to insert one end of the tool to complete the removal of the knockout hole structure 2. If the knockout hole structure 2 is set at the edge of the side of the shell, then there is no need to set the avoidance hole 3, and the knockout hole structure 2 can be directly removed from the edge using a tool during operation.

[0036] Furthermore, in order to improve the flexibility of the shell and adapt to the wire outlet positions in more situations, the knock-out hole structure 2 can be set on multiple sides of the shell. When in use, only the knock-out hole structure 2 at the corresponding position needs to be removed, and the remaining knock-out hole structures 2 remain unchanged without affecting the appearance of the product.

[0037] Embodiment 2

[0039] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.
