Description

Technical Field

[0001] The utility model relates to the field of fire extinguishers, in particular to a fire extinguisher testing tool. Background Art

[0002] A fire extinguisher is a portable fire-fighting tool. Chemicals are placed inside the fire extinguisher to extinguish fires. Fire extinguishers are one of the common fire-fighting equipment. During the production process of fire extinguishers, the internal air tightness needs to be tested. At this time, a test tool is needed. During the test, the fire extinguisher must first be fixed on the table using a clamping mechanism, and then the gas pipe is connected to the fire extinguisher for subsequent air tightness testing.

[0003] Existing fire extinguisher air tightness tests mostly use a clamping mechanism to fix the fire extinguisher in a certain position. The traditional clamping mechanism is that the staff rotates the threaded rod, so that the threaded rod drives the threaded sleeve to slide and push, thereby completing the limit clamping of the fire extinguisher. However, this clamping process is mostly done manually, which wastes too much manpower and material resources. It is difficult for the staff to control the clamping force. Once the clamping is excessive, it is easy to cause the fire extinguisher shell to deform, thereby affecting subsequent use.

[0004] In summary, the above device wastes too much manpower and material resources during the testing process, and is very likely to cause deformation of the fire extinguisher shell, thereby affecting subsequent use. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a fire extinguisher testing tool to solve the technical problems of excessive waste of manpower and material resources during the testing process, and at the same time easily causing deformation of the fire extinguisher shell, thereby affecting subsequent use.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a fire extinguisher testing tool, comprising a test bench, a placement groove is provided on the top of the test bench, and a placement plate is slidably arranged inside the placement groove, the bottom of the placement plate passes through the test bench and is elastically provided with a gear column, and a fixed gear is meshed on one side of the gear column, a threaded rod that cooperates with the fixed gear is rotatably arranged in the test bench, and clamping plates that cooperate with the threaded rod are symmetrically arranged on both sides of the placement plate.

[0007] By adopting the above technical solution, the placement plate slides downward under the action of the fire extinguisher's own gravity. During this process, the gear column drives the fixed gear on one side to rotate, and drives the threaded rod to rotate under the action of the transmission mechanism, and at the same time drives the clamping plate to clamp the outer wall of the fire extinguisher, thereby accelerating the overall disassembly and assembly efficiency, effectively reducing the testing burden of the staff, and thus ensuring that the outer wall of the fire extinguisher will not be damaged during the clamping process.

[0008] The utility model is further configured such that an arc-shaped clamping plate is elastically connected to the inner side of the clamping plate, and a sliding rod is provided at one end of the arc-shaped clamping plate, a socket is provided on the sliding rod, and an insertion rod matching the socket is provided on the clamping plate.

[0009] By adopting the above technical solution, in the process of the clamping plate driving the arc clamping plate to clamp the fire extinguisher, the compression spring on one side of the arc clamping plate will be gradually compressed, and then when the socket on the slide rod moves to the bottom of the insertion rod, the insertion rod completes the limiting work of the slide rod. At this time, the arc clamping plate itself is in a compressed state. Then, after the air tightness test of the fire extinguisher is completed, the staff pulls out the insertion rod and takes out the fire extinguisher by swinging it left and right, and the arc clamping plate is reset under the reset action of the compression spring. In this process, the fire extinguisher can be quickly disassembled and assembled.

[0010] The present invention is further configured such that transmission mechanisms are symmetrically provided on both sides of the fixed gear, and the other end of the transmission mechanism is connected to the threaded rod.

[0011] By adopting the above technical solution, when the gear column slides downward through the placement plate, it will drive the fixed gear on one side to rotate, and at the same time realize the rotation of the transmission mechanism, so that the threaded rod at the other end rotates.

[0012] The utility model is further configured such that a threaded sleeve is slidably provided on the outer wall of the threaded rod, a support frame is provided on the top of the threaded sleeve, and the other end of the support frame is connected to the clamping plate.

[0013] By adopting the above technical solution, during the rotation of the threaded rod, the threaded sleeve will slide to one side. During this process, the threaded sleeve and the support frame cooperate to drive the clamping plate to slide to one side, thereby completing the limited clamping work of the fire extinguisher.

[0014] The utility model is further configured as follows: the transmission mechanism includes a driving disc, a transmission belt and a driven disc, the driving disc and the driven disc are connected by a transmission belt, one end of the fixed gear is connected to the driving disc, and one end of the driven disc is connected to the threaded rod, and the diameter of the driving disc in the transmission mechanism is larger than the diameter of the driven disc.

[0015] By adopting the above technical solution, when the placement plate drives the gear column to move downward, the fixed gear will rotate, thereby driving the active disk to rotate, and through the action of the transmission belt, the driven disk drives the threaded rod to rotate accordingly. Since the diameter of the active disk in the transmission mechanism is larger than the diameter of the driven disk, when the fixed gear drives the active disk to rotate several times, the driven disk will drive the threaded rod at one end to rotate several times.

[0016] The utility model is further configured such that the top of the placement plate is provided with a rough surface.

[0017] By adopting the above technical solution, the provision of the rough surface facilitates increasing the sliding friction between the placement plate and the fire extinguisher, thereby ensuring the stability of the fire extinguisher on the placement plate.

[0018] The present invention is further configured such that limiting mechanisms are provided on both sides of the threaded sleeve in the test bench.

[0019] By adopting the above technical solution, the limiting mechanism prevents the threaded sleeve from rotating during the rotation of the threaded rod, thereby further improving the sliding stability of the clamping plate itself.

[0020] In summary, the present invention has the following beneficial effects:

[0021] The utility model places the fire extinguisher to be tested on the top of the placement plate, and then slides the placement plate downward under the action of the fire extinguisher's own gravity. During this process, the gear column drives the fixed gear on one side to rotate, and drives the threaded rod to rotate under the action of the transmission mechanism, and at the same time drives the clamping plate to clamp the outer wall of the fire extinguisher, thereby accelerating the overall disassembly and assembly efficiency, effectively reducing the testing burden of the staff, and thus ensuring that the outer wall of the fire extinguisher will not be damaged during the clamping process.

[0027] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] The following describes an embodiment of the present invention based on its overall structure.

[0029] Example 1

[0030] A fire extinguisher test tool, such as Figure 1-Figure 3 As shown, it includes a test bench 1, a test mechanism, a transmission mechanism 5, a clamping mechanism and a reset mechanism. A placement slot 2 is provided on the top of the test bench 1, and a placement plate 3 is slidingly provided inside the placement slot 2. The staff places the fire extinguisher to be tested on the top of the placement plate 3, and then the placement plate 3 slides downward under the action of the fire extinguisher's own gravity. Since the bottom of the placement plate 3 passes through the test bench 1 and is elastically provided with a gear column 7, and a fixed gear 6 is engaged on one side of the gear column 7, the placement plate 3 drives the gear column 7 to slide downward, and the fixed gear 6 is driven to rotate in the process of the fixed gear 6 being driven by the gear column 7. Transmission mechanisms 5 are symmetrically provided on both sides of the fixed gear 6, and the other end of the transmission mechanism 5 is connected to the threaded rod 9. In the process of the gear column 7 rotating, the transmission mechanism 5 is rotated at the same time, so that the threaded rod 9 at the other end is rotated. The cam 10 is connected to the support frame 8 at the other end thereof, and the cam 10 is connected to the support frame 8 at the other end thereof. When the cam 10 is in rotation, the cam 10 slides to one side. During this process, the cam 10 cooperates with the support frame 8 to drive the cam 4 to slide to one side, thereby completing the limit clamping of the fire extinguisher. The fire extinguisher is then tested for air tightness by the testing mechanism. After the test is completed, the fire extinguisher is taken out, and the gear column 7 drives the placement plate 3 to slide upward under the action of the elastic component, so as to facilitate the subsequent air tightness test of the next group of fire extinguishers, thereby accelerating the overall disassembly and assembly efficiency, effectively reducing the testing burden of the staff, and thus achieving the goal of not causing damage to the outer wall of the fire extinguisher during the clamping process.

[0031] See also Figure 2 The transmission mechanism 5 includes a driving disc, a transmission belt and a driven disc. The driving disc is connected to one end of the fixed gear 6, and one end of the driven disc is connected to the threaded rod 9. When the placement plate 3 drives the gear column 7 to move downward, the fixed gear 6 will rotate, thereby driving the driving disc to rotate. Under the action of the transmission belt, the driven disc drives the threaded rod 9 to follow and rotate. Since the diameter of the driving disc in the transmission mechanism is larger than the diameter of the driven disc, when the fixed gear 6 drives the driving disc to rotate several times, the driven disc will drive the threaded rod 9 at one end to rotate several times.

[0032] Example 2

[0033] like Figure 4The fire extinguisher testing tool shown in the figure has an overall structure similar to that of Example 1, wherein the inner side of the clamping plate 4 is elastically connected with an arc-shaped clamping plate 14, and a sliding rod 12 is provided at one end of the arc-shaped clamping plate 14, a socket 15 is opened on the sliding rod 12, and an insertion rod 11 cooperating with the socket 15 is provided on the clamping plate 4. In the process of the clamping plate 4 driving the arc-shaped clamping plate 14 to clamp the fire extinguisher, the compression spring 13 on one side of the arc-shaped clamping plate 14 will gradually compress. Then, when the socket 15 on the sliding rod 12 moves to the bottom of the insertion rod 11, the insertion rod 11 completes the limiting work of the sliding rod 12. At this time, the arc-shaped clamping plate 14 itself is in a compressed state. Then, after the air tightness test of the fire extinguisher is completed, the staff pulls out the insertion rod 11 and takes out the fire extinguisher by swinging it left and right, and the arc-shaped clamping plate 14 is reset under the reset action of the compression spring 13. In this process, the fire extinguisher can be quickly disassembled and assembled.

[0034] The working principle of the present invention is as follows: when in use, the fire extinguisher to be tested is placed on the top of the placement plate 3, and then the placement plate 3 is driven to move downward under the action of the fire extinguisher's own gravity, thereby driving the gear column 7 to move downward, so that the fixed gear 6 engaged on one side rotates. In this process, the threaded rod 9 is driven to rotate under the action of the transmission mechanism 5, thereby driving the clamping plate 4 to limit and clamp the fire extinguisher, thereby completing the air tightness test of the fire extinguisher. The subsequent staff directly takes out the fire extinguisher, and under the action of the elastic component, the gear column 7 drives the placement plate 3 to reset and slide upward, which is convenient for the subsequent air tightness test of the next group of fire extinguishers.
