Description

Technical Field

[0001] This utility model belongs to the field of digital display technology, specifically relating to a digital display with a hook position that is reliably maintained. Background Technology

[0002] Currently, the hooks on smart valve gauges and pressure gauges used in HVAC repair lack damping, allowing the hooks to move freely. During use, once the hooks are opened, they cannot remain upright, requiring the user to hold the hook and hang the product on the air conditioning grille. After use, when removing the digital display gauge, the user typically holds the casing upwards, but due to the hook's free movement, gravity causes it to remain attached to the grille. Therefore, two hands are needed to remove the gauge; one hand holds the casing and the hook to remove it, making the process inconvenient. Retrieving the gauge with both hands while working at heights poses a safety hazard and increases the risk of accidents.

[0003] In addition, the thick bulge of the battery after long-term use also poses a safety hazard. Utility Model Content

[0004] This invention addresses the inconvenience caused by the lack of rotational resistance in the hooks of existing digital displays, by providing a digital display with a reliably maintained hook position. By generating damping between the hook and the watch case, the hook position can be maintained, making it easy to pick up and put down.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a digital display for reliably maintaining the hook position, wherein the digital display for reliably maintaining the hook position includes:

[0006] Case;

[0007] A swing assembly, which can swing up and down, is located on the rear side of the watch case and includes a hook;

[0008] The oscillating component forms a hook-and-hold structure with the watch case.

[0009] The present invention relates to a digital display watch with a reliably maintained hook position. The swing component and the watch case form a hook position holding structure, so that the hook can be reliably held in the hook position. Unlike the prior art where the hook moves freely and can be taken out or put back by operating the watch case without operating the hook, it is more convenient to take out and put back.

[0010] As an improvement, the oscillating component has rotational damping between itself and the watch case, forming the aforementioned hook position holding structure.

[0011] As an improvement, a left-right oscillation groove is formed on the watch case, and the oscillation assembly also includes an oscillation column disposed in the oscillation groove, with a compressed elastic damping element disposed on the oscillation column.

[0012] As an improvement, the elastic damping element is an O-ring; and / or,

[0013] There are two elastic damping elements located on the left and right sides of the connection between the hook and the swing column; and / or,

[0014] An annular groove is formed on the swing column, and an elastic damping element is installed in the annular groove; and / or,

[0015] The elastic damping element protrudes radially outward from the swing column.

[0016] As an improvement, the front of the oscillating groove is open for inserting the oscillating column, and the rear of the oscillating groove has a notch for inserting a hook. The digital display also includes a pressure block in the watch case that closes the opening of the oscillating groove. The watch case includes a front half and a rear half; or...

[0017] The rear side of the oscillating groove is open for the insertion of the oscillating column. The digital display also includes a pressure block in the case that closes the opening of the oscillating groove. The pressure block has a notch for the insertion of a hook. The case includes a front half and a rear half.

[0018] As an improvement, the pressure block is fixed to the watch case by screws; and / or,

[0019] A sealing ring is provided between the pressure block and the swing groove; and / or,

[0020] The pressure block abuts against the elastic damping component.

[0021] As an improvement, the swing assembly is engaged with the watch case to form the aforementioned hook position holding structure, with at least one engagement point located in the hook position of the hook.

[0022] As an improvement, a snap-fit ​​protrusion is formed on the watch case, and the oscillating assembly includes an oscillating column with multiple circumferential snap-fit ​​grooves formed on the oscillating column. The snap-fit ​​protrusion and the snap-fit ​​grooves cooperate to form the aforementioned hook position holding structure.

[0023] As an improvement, a storage position retention structure is formed on the back side of the watch case. The storage position retention structure includes an upper protrusion, a lower protrusion, and an elastic element provided on the upper protrusion. The gap between the upper protrusion and the lower protrusion is greater than the diameter of the hook, and the gap between the elastic element and the lower protrusion is smaller than the diameter of the hook.

[0024] As an improvement, a battery slot is formed in the watch case. The digital watch also includes a battery disposed in the battery slot and an elastic pressure plate for fixing the battery. The elastic pressure plate includes an H-shaped flat plate and L-shaped portions extending backward from the four corners of the flat plate. The L-shaped portions include horizontal portions and vertical portions. Mounting holes are provided on the four vertical portions, and screws are disposed in the mounting holes. Deformation grooves are formed between the two upper L-shaped portions and between the two lower L-shaped portions.

[0025] The beneficial effect of the digital display watch with reliable hook position retention of this utility model is that a hook position retention structure is formed between the swing component and the watch case, so that the hook can be reliably kept in the hook position, unlike the prior art where the hook moves freely and can be taken out and put back by operating the watch case without operating the hook, making it more convenient to take out and put back.

[0044] The technical solutions of the embodiments of this utility model are explained and described below. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model.

[0045] See Figures 1 to 9 The present invention relates to a digital display for reliably maintaining the hook position, comprising:

[0046] Case;

[0047] A swing assembly, which can swing up and down, is located on the rear side of the watch case and includes a hook;

[0048] The oscillating component forms a hook-and-hold structure with the watch case.

[0049] The present invention relates to a digital display watch with a reliably maintained hook position. The swing component and the watch case form a hook position holding structure, so that the hook can be reliably held in the hook position. Unlike the prior art where the hook moves freely and can be taken out or put back by operating the watch case without operating the hook, it is more convenient to take out and put back.

[0050] Example 1

[0051] See Figures 1 to 8 The digital display for reliably maintaining the position of the hook 21 in Embodiment 1 of this utility model includes:

[0052] Case 1;

[0053] The swing assembly 2 is disposed on the rear side of the watch case 1 and can swing up and down, including a hook 21;

[0054] Among them, the swing component 2 and the watch case 1 form a hook position holding structure.

[0055] In this embodiment, the swing assembly 2 and the watch case 1 have rotational damping, forming the aforementioned hook position holding structure. The rotational damping allows the swing assembly 2, including the hook 21, to remain at any position rather than a set of fixed positions.

[0056] In this embodiment, a swing groove 121 in the left-right direction is formed on the watch case 1. The swing assembly 2 also includes a swing column 22 disposed in the swing groove 121. A compressed elastic damping element 3 is disposed on the swing column 22. The elastic damping element 3 is located between the swing column 22 and the watch case 1.

[0057] In this embodiment, an anti-detachment groove 222 is formed on the swing column 22, and an anti-detachment protrusion is formed at the upper end of the hook 21. The anti-detachment groove 222 is a stepped groove, and most of the anti-detachment protrusion is located in the anti-detachment groove 222. An avoidance groove is formed on the watch case 1 to avoid the anti-detachment protrusion.

[0058] In this embodiment, the elastic damping element 3 is an O-ring. O-rings are mature products, readily available, and inexpensive.

[0059] In this embodiment, there are two elastic damping elements 3 located on the left and right sides of the connection between the hook 21 and the swing column 22, which has a reasonable structure and symmetrical force distribution.

[0060] In this embodiment, an annular groove is formed on the swing column 22, and the elastic damping element 3 is installed in the annular groove, with the elastic damping element 3 protruding radially outward from the swing column 22. In other embodiments, the elastic damping element 3 may also be disposed between the left and right end faces of the swing column 22 and the watch case 1.

[0061] In this embodiment, the front side of the swing groove 121 is open for the swing column 22 to be inserted, and the rear side of the swing groove 121 has a notch for the hook 21 to be inserted. The digital display also includes a pressure block 4 in the case 1 that closes the opening of the swing groove 121. The case 1 includes a front half case 11 and a rear half case 12.

[0062] In other embodiments, the rear side of the swing groove 121 is open for the insertion of the swing column 22. The digital display also includes a pressure block 4 disposed in the watch case 1 to close the opening of the swing groove 121. The pressure block 4 has a notch for the hook 21 to be inserted. The watch case 1 includes a front half 11 and a rear half 12. In this case, the hook 21 and the swing column 22 can also be integrally formed.

[0063] In other embodiments, a damping structure may not be used. For example, the oscillating component 2 may be engaged with the watch case 1 to form the aforementioned hook position holding structure, with at least one engagement point located at the hook position of the hook 21. The oscillating component 2 and the watch case 1 may have multiple hook position engagement points. Specifically, a toothed structure may be used.

[0064] In this embodiment, the pressure block 4 is fixed to the watch case 1 by screws, and the screws connecting the pressure block 4 and the watch case 1 are installed from front to back.

[0065] In this embodiment, a sealing ring 5 is provided between the pressure block 4 and the swing groove 121 to seal the pressure block 4 and the watch case 1.

[0066] In this embodiment, the pressure block 4 abuts against the elastic damping element 3.

[0067] In this embodiment, a storage position holding structure is formed on the rear side of the watch case 1. The storage position holding structure includes an upper protrusion 81, a lower protrusion 82, and an elastic member 83 disposed on the upper protrusion 81. The gap between the upper protrusion 81 and the lower protrusion 82 is greater than the diameter of the hook 21, and the gap between the elastic member 83 and the lower protrusion 82 is smaller than the diameter of the hook 21.

[0068] See Figure 8 In this embodiment, a battery slot 123 is formed in the casing 1. The digital display also includes a battery 6 disposed in the battery slot 123 and an elastic pressure plate 7 for fixing the battery 6. The elastic pressure plate 7 is generally vertically H-shaped. The length direction of the battery 6 is consistent with the left-right direction of the digital display. The elastic pressure plate 7 includes an H-shaped flat plate portion 71 and L-shaped portions 72 extending rearward from the four corners of the flat plate portion 71. The L-shaped portions 72 include a horizontal portion and a vertical portion. Mounting holes are formed on the four vertical portions, and screws are installed in the mounting holes. The elastic pressure plate 7 also includes a reinforcing rib extending rearward from the center of the flat plate portion 71. A deformation groove 73 is formed between the two upper L-shaped portions 72 and between the two lower L-shaped portions 72, which facilitates the deformation of the elastic pressure plate 7 to accommodate the bulging battery 6, reduce the force on the bulging battery 6, and reduce safety risks.

[0069] In this embodiment, a positioning post is also formed on the case 1, and a positioning hole is formed on the elastic pressure plate 7, with the positioning post positioned in the positioning hole. There are two positioning posts and positioning holes. Both the positioning hole and the mounting hole can be oblong holes, which is more conducive to the deformation of the elastic pressure plate 7.

[0070] In this embodiment, the swing angle of the swing component 2 is approximately 180°.

[0071] In this embodiment, the watch case 1 includes a front half-case 11 and a rear half-case 12, and the swing assembly 2 is mounted on the rear half-case 12. The screen is mounted on the front half-case 11.

[0072] In this embodiment, the digital display includes a meter body assembly 01 and a valve body assembly 02. The meter body assembly 01 includes a meter case 1 and an oscillating component 2, etc. A sensor is provided in the meter case 1, and the valve body assembly 02 includes a valve seat, etc. The sensor has an external thread, and the valve seat has a threaded hole 1. The external screw of the sensor is screwed into the threaded hole 1, and the front half shell 11 and the rear half shell 12 of the meter case 1 hold the sensor.

[0073] In this embodiment, during assembly, the two elastic damping elements 3 are first installed on the swing column 22, then the swing column 22 is placed into the swing groove 121, and then the anti-detachment part of the hook 21 is inserted into the anti-detachment groove 222 of the swing column 22. Finally, the pressure block 4 is used to press down the swing column 22 and fix it in the swing groove 121.

[0074] The beneficial effects of the digital display watch with reliably maintained hook 21 position according to Embodiment 1 of this utility model are as follows: A hook position holding structure is formed between the swing component 2 and the watch case 1, so that the hook 21 can be reliably held in the hook position, unlike the prior art where the hook 21 moves freely and can be taken out and put back by operating the watch case 1 without operating the hook 21, making it more convenient to take out and put back; The use of elastic damping component 3 allows the hook 21 to be held in any position; The elastic damping component 3 uses an O-ring; A sealing ring 5 is provided between the pressure block 4 and the watch case 1 to achieve sealing at this point; The elastic pressure plate 7 that fixes the battery 6 is deformable. When the battery 6 bulges (usually the thickness dimension increases by 10%), the deformation of the elastic pressure plate 7 can reduce the force on the battery 6 and reduce safety hazards.

[0075] Example 2

[0076] See Figure 9 In this embodiment, the swing component 2 is engaged with the watch case 1 to form the aforementioned hook position holding structure, and at least one engagement point is located at the hook position of the hook 21.

[0077] In this embodiment, a snap-fit ​​protrusion 122 is formed on the watch case 1, and the swing assembly 2 includes a swing post 22. A plurality of circumferential snap-fit ​​grooves 223 are formed on the swing post 22. The snap-fit ​​protrusion 122 and the snap-fit ​​grooves 223 cooperate to form the aforementioned hook position holding structure. The cross-sections of both the snap-fit ​​protrusion 122 and the snap-fit ​​grooves 223 are arc-shaped.

[0078] The difference between Embodiment 2 and Embodiment 1 is that the elastic damping element 3 is removed, and the position of the hook 21 is maintained by the snap-fit ​​protrusion 122 on the watch case 1 and the snap-fit ​​groove 223 of the swing column 22 of the swing assembly 2.
