DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0021] Please refer to Figures 1 to 3 The utility model provides a technical scheme: a heat dissipation type pressure gauge, including pressure gauge 1, pressure gauge 1 bottom surface fixedly connected with mounting thread 2, pressure gauge 1 surface is slidably connected with a plurality of fins 3 above mounting thread 2, and the fin 3 side is provided with adjusting assembly 4;

[0022] Adjusting assembly 4 includes fixed frame 41 fixedly connected to the surface of pressure gauge 1, and the inner wall of fixed frame 41 is rotatably connected with bidirectional threaded rod 42, and the one end of bidirectional threaded rod 42 extends out fixed frame 41 and is fixedly connected with knob 43, and the inner wall of fixed frame 41 is fixedly connected with guide rod 44 on the one side of bidirectional threaded rod 42, and the surface of bidirectional threaded rod 42 is screw-connected with a plurality of adjusting seats 45, and adjusting seat 45 and guide rod 44 are slidably connected, and the one end of adjusting seat 45 is rotatably connected with first transmission rod 46, and the one side of first transmission rod 46 is rotatably connected with second transmission rod 47, and first transmission rod 46 and second transmission rod 47 are rotatably connected between second transmission rod 47 and adjusting seat 45, between adjacent two first transmission rods 46 and between adjacent two second transmission rods 47, and the one side of first transmission rod 46 and second transmission rod 47 close to pressure gauge 1 is fixedly connected with connecting rod 48, and connecting rod 48 and fin 3 are fixedly connected.

[0023] Through mounting thread 2, pressure gauge 1 can be connected to the surface of the object to be measured, and the heat dissipation of pressure gauge 1 can be realized by matching a plurality of fins 3 in the process of daily use, so that the accuracy of measurement is prevented from being affected due to the high temperature, and even the problem of internal structural components being melted and damaged is prevented.

[0024] When the spacing between a plurality of fins 3 needs to be adjusted according to actual conditions, knob 43 is rotated, and cooperating with bidirectional threaded rod 42, fixed frame 41, adjusting seat 45, first transmission rod 46, second transmission rod 47 and connecting rod 48 drives fin 3 to slide along the surface of pressure gauge 1, so that the spacing between a plurality of fins 3 can be adjusted, so that pressure gauge 1 can be applied to different working environments, and the subsequent cleaning and maintenance of fin 3 are facilitated.

[0025] Please refer to Figures 1 to 4The utility model provides a technical scheme: the top fixedly connected with observation rod 5 has the scale fixedly connected with observation rod 5 surface, the scale surface is coated with fluorescent layer, and the top of fixed frame 41 is located above observation rod 5 and is provided with the hole 6 for making room. When adjusting seat 45 moves along the surface of bidirectional screw rod 42, the observation rod 5 fixed to its top will be lifted in the hole 6 for making room provided in the top of fixed frame 41, and the scale fixed to the surface of observation rod 5 is convenient for accurately adjusting the spacing between several radiating fins 3, and since the scale surface is coated with fluorescent layer, the scale can be clearly read in dim light.

[0026] The top of fixed frame 41 is movably connected with magnifying glass 7 on one side of observation rod 5, and magnifying glass 7 is fixed between fixed frame 41 through bolt. The scale on the surface of observation rod 5 is read through magnifying glass 7, and since magnifying glass 7 is fixed between fixed frame 41 through bolt, magnifying glass 7 can be detached from the surface of fixed frame 41.

The center of hole 6 for making room and the center of observation rod 5 are located on the same vertical line, and the diameter of hole 6 for making room is slightly larger than the diameter of observation rod 5, so that observation rod 5 will not rub against hole 6 for making room when it is lifted in hole 6 for making room. Thus, the scale on the surface of observation rod 5 is prevented from being abraded.

[0028] The top of radiating fin 3 is in the shape of a circular truncated cone, and the inner wall of radiating fin 3 is attached to the surface of pressure gauge 1. The top of radiating fin 3 is in the shape of a circular truncated cone, so that the dust falling on the top of radiating fin 3 can be guided to the outside of pressure gauge 1, thereby reducing the accumulation of dust on the surface of radiating fin 3 and improving the heat dissipation effect of radiating fin 3. The inner wall of radiating fin 3 is attached to the surface of pressure gauge 1, so that the inner wall of radiating fin 3 has sufficient contact area with pressure gauge 1, thereby ensuring the heat dissipation effect of radiating fin 3 on pressure gauge 1.

[0029] Fixed frame 41 is in the shape of "L", and the length of fixed frame 41 is greater than the radius of radiating fin 3. Fixed frame 41 is in the shape of "L", and the length of fixed frame 41 is greater than the radius of radiating fin 3, so that radiating fin 3 will not contact fixed frame 41 during adjustment, thereby reducing the abrasion between fixed frame 41 and radiating fin 3 during use.

[0030] Specific implementation: pressure gauge 1 is connected to the surface of the object to be measured through mounting thread 2 fixed to the bottom surface of pressure gauge 1. During daily use, pressure gauge 1 can be cooled through several radiating fins 3 connected to the surface of pressure gauge 1 through sliding connection, thereby preventing the accuracy of measurement from being affected due to high temperature, and even preventing the internal structural components from being melted and damaged.

[0031] When it is necessary to adjust the spacing between the plurality of heat dissipation fins 3 according to the actual situation, the knob 43 is rotated, the knob 43 will drive the two-way threaded rod 42 connected with it to rotate in the fixed frame 41 fixed on one side of the pressure gauge 1, and then drive the plurality of adjusting seats 45 to move along the surface of the two-way threaded rod 42, and then drive the first transmission rod 46 and the second transmission rod 47 connected on one side of the adjusting seat 45 to rotate, and then drive the connecting rod 48 connected on one side of the first transmission rod 46 and the second transmission rod 47 to move, and then drive the heat dissipation fins 3 fixed on one end of the connecting rod 48 to slide along the surface of the pressure gauge 1, that is, the spacing between the plurality of heat dissipation fins 3 can be adjusted, so that the pressure gauge 1 can be applied to different working environments, and the heat dissipation fins 3 are convenient for subsequent cleaning and maintenance.

[0032] In addition, it should be understood that, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be combined appropriately to form other embodiments that those skilled in the art can understand.
