Description

Technical Field

[0001] The utility model relates to the field of pressure gauges, in particular to a novel pressure gauge structure. Background Art

[0002] A jack is a lightweight lifting device that uses a rigid lifting member as a working mechanism, lifting heavy objects within a short stroke using a top support or bottom claw. Jacks are primarily used in factories, mines, transportation, and other sectors for vehicle repair and other lifting and support tasks. Currently, tensioning jacks are primarily used in coal mines and construction to tension strands or rebar, using anchors for pre-tensioning. These jacks require a hydraulic pump station for pressure supply and automatic or manual valve control. The pre-tension force is displayed on a pressure gauge.

[0003] In the existing pressure gauge structure of the mining jack, the battery is usually a snap-on connection structure. When encountering bumps or falls, the vibration force will be transmitted to the battery, causing the snap-on connection structure between the battery and the pressure gauge body to loosen, resulting in the battery often detaching from the pressure gauge body when the pressure gauge is bumped or falls, thereby affecting the use effect and structural stability of the pressure gauge. It is necessary to improve it. Summary of the Invention

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts, any modifications, equivalent replacements, improvements, etc., shall be included in the scope of protection of the present invention.

[0023] like Figures 1 to 4 As shown, this embodiment discloses a new type of pressure gauge structure, including a pressure gauge body 1, a battery cavity 101 is provided on the pressure gauge body 1, and a battery component 2 is installed through the battery cavity 101; the battery cavity 101 is in the shape of a rectangular column cavity with one end open, the battery component 2 is a rectangular column structure, and one end of the battery component 2 is fixedly connected to an end cover 201; a limiting ridge 102 is provided on the inner wall of the battery cavity 101, and the length direction of the limiting ridge 102 is consistent with the length direction of the battery cavity 101, and a limiting groove 202 adapted to the limiting ridge 102 is provided on the outer wall of the battery component 2, and the battery component 2 is inserted into the battery cavity 101 from the port position of the battery cavity 101 and the limiting ridge 102 is inserted into the corresponding limiting groove 202; a snap groove 103 is provided at one end of the limiting ridge 102 close to the port of the battery cavity 101, and an elastic snap 203 is provided at one end of the limiting groove 202 close to the end cover 201, and a control button 206 is provided on one side of the end cover 201, which is connected to the elastic snap 203 and controls the protruding state of the elastic snap 203; when the battery component 2 is inserted into the battery cavity 101, the elastic snap 203 is engaged with the snap groove 103 to prevent the battery component 2 from escaping from the battery cavity 101; when the control button 206 is pressed, the engagement between the elastic snap 203 and the snap groove 103 can be released.

[0024] The battery cavity 101 is provided with a limiting ridge 102 in the middle of the four side walls, and the battery component 2 is provided with a limiting groove 202 adapted to the limiting ridge 102 on the four side walls; the limiting ridges 102 on the left and right inner walls of the battery cavity 101 are provided with a snap groove 103 at one end, and the battery component 2 is provided with an elastic snap 203 corresponding to the snap groove 103 on the left and right side walls, and the two elastic snaps 203 are connected to the control button 206.

[0025] After the battery component is inserted into the battery cavity, there is a certain gap between the inner wall end face of the limiting ridge and the end face of the limiting groove. That is to say, the coordinated design of the limiting ridge and the limiting groove only realizes the position limitation between the battery component and the battery cavity. The limiting ridge does not support the inner wall of the battery component. The battery component is mainly supported in the battery cavity by four arc ridges.

[0026] The end of the limiting ridge 102 close to the battery cavity 101 port is configured as an inclined guide structure, and the inclined guide structure gradually becomes smaller from the position away from the battery cavity 101 port to the position close to the battery cavity 101 port in the thickness direction of the limiting ridge 102.

[0027] This design facilitates the accurate and rapid insertion of the limiting ridge into the limiting groove when the battery component is inserted into the battery cavity, thereby improving the assembly convenience between the battery component and the pressure gauge body.

[0028] Arc bosses are provided at the prism positions around the battery component 2, and the length direction of the arc bosses is consistent with the length direction of the battery component 2; arc grooves 104 are provided at the corners around the battery cavity 101, and the length direction of the arc grooves 104 is consistent with the length direction of the battery cavity 101; when the battery component 2 is inserted into the battery cavity 101, the outer side of the arc bosses is embedded in the arc grooves 104.

[0029] The arc boss is composed of a plurality of cylindrical boss sections 204 , which are arranged at equal intervals along the length direction of the battery component 2 . The length direction of the boss sections 204 is consistent with the length direction of the battery component 2 , and blocking intervals 205 are provided between adjacent boss sections 204 .

[0030] The boss section 204 is a boss section with a rubber structure or a boss section with a plastic structure.

[0031] The blocking interval can block the transmission of vibration force to adjacent convex column sections. At the same time, designing the convex column section as a rubber structure can effectively reduce the vibration force during the transmission process of the vibration force, thereby achieving a certain vibration buffering effect.

[0032] The depth of the arc groove 104 is smaller than the diameter of the convex column section 204; when the battery component 2 is inserted into the battery cavity 101, the outer side of the convex column section 204 is embedded in the arc groove 104, and a heat dissipation gap 105 is formed between the outer wall of the battery component 2 and the inner wall of the battery cavity 101; the pressure gauge body 1 is provided with a heat dissipation hole connected to the heat dissipation gap 105, and the heat dissipation gap 105 is connected to the outside world through the heat dissipation hole.

[0033] The heat dissipation holes include a first heat dissipation hole 106 and a second heat dissipation hole 207. The first heat dissipation hole 106 is arranged on the end wall of one end of the battery cavity 101 in the longitudinal direction, and the second heat dissipation hole 207 is arranged on the end cover 201 at one end of the battery component 2; the first heat dissipation hole 106 and the second heat dissipation hole 207 are arranged correspondingly.

[0034] Through the design of the heat dissipation gaps and heat dissipation holes, the temperature generated by the battery components during operation can be dissipated, so that the higher temperature generated by the battery components during operation can be discharged to the outside through the heat dissipation gaps and heat dissipation holes, thereby achieving a heat dissipation effect on the battery components; at the same time, the design of the first heat dissipation holes and the second heat dissipation holes can achieve air convection at both ends of the heat dissipation gap, thereby improving its air circulation effect and thus improving its heat dissipation effect.

[0035] After the utility model is installed, the battery component is inserted into the battery cavity of the pressure gauge body, the limiting convex strips on the inner wall of the battery cavity are inserted into the limiting grooves on the battery component, the arc convex columns on the prisms around the battery component are inserted into the arc grooves on the corners around the battery cavity, and the elastic buckles are engaged with the buckle grooves; at this time, the battery component is supported in the battery cavity by the arc convex columns and is in a suspended state. When the pressure gauge is bumped or dropped, the vibration force will be transmitted from the pressure gauge body to the corners of the battery component through the arc convex columns, and will not affect the buckle structure at the side wall of the battery component, thereby avoiding the buckle loosening and separation between the battery component and the pressure gauge body, and improving the structural stability of the pressure gauge;

[0036] Moreover, by configuring the arc boss to be composed of a plurality of boss sections, the vibration force cannot be transmitted to the adjacent boss section structure through the boss section, thereby achieving a vibration force blocking effect and further avoiding the vibration force from affecting the snap connection structure of the battery component. At the same time, since the structural strength of the corners is the highest in the design structure of the battery, the vibration force will not have any effect on the internal structure of the battery component when it is transmitted to the corners of the battery component through the arc boss, thereby avoiding damage to the internal structure of the battery component when it is bumped or dropped, extending the service life of the battery component, and improving the use effect of the pressure gauge.
